Abstract

The main objective is to develop the automatic jack system for 4 wheelers using an android app. To facilitate the repair during flat tire condition the jack is used to raise the rear and the front part of the car. Usually, a flat tire is not a pleasant condition for the people who prefer long drives and for aged people, whenever the flat tire takes place the person need to squat down or bend down to place the jack. To encounter placing the jack by manual method, the design resembles the automatic process just by controlling through an android device.

Introduction

In an automotive vehicle the cases of the flat tire are common, and in the in the traditional method of fixing the flat tire, first step is the detaching the wheel from an automotive vehicle which is a tough task in case if there are old people or an ill person is traveling in the car. It becomes risky for them to deal with the situation, this motivated us to come up with the idea of Automatic jack system for the automotive vehicles which is controlled by the Bluetooth with the help of an android app.

Usually, jack is used to lift the vehicle or heavy load or to apply the great force which is also a mechanical device. The various types of jacks are:

a) House jack or Screw jack

b) Hydraulic jack

c) Pneumatic jack

d) Screw jack

e) Scissor jack

These above jacks are usually operated manual, which includes the person to place the jack in the position where the flat tire takes place. There is the availability of electric scissor jack, which will be powered by the 12v battery to lift the car (Figure 1).

Features of Electric Jack:

• Ton Max Load Capacity (2,000 lbs) Max

• Button Push Button Controller with 12 Ft Cord

The mechanism of the electric jacks remains same compared to the normal jacks, but having the advantage to run on the electricity, which in this work power is usually supplied through the 12 V from the car battery itself. To perform a function in the electric jack it needs to combine both mechanical and electrical energy. And this process which includes the opening and closing the jack is controlled by the remote control. The lifting capacity varies from the different electric jack, which can lift up to 1tonne, 1.5 tonne and 2 tonne.

The factors which made us select the electric jack are:

a) High-quality

b) Saves time and energy

c) It can withstand high pressure

And also electric jacks come with warranty.

Related Work

In paper, Noor et al. [1] developed an auto car jack using the internal power which is the 12 V power supply. During the emergency required the work resembles acquiring the power supply from the internal cigarette lighter power (12 Volt). The jack preferred is the hydraulic jack by the advantage of the greater lift and also a powerful jack. To ensure the power is adequate and to increase the lifting power the gear ratio is being used.

In paper, Sainath et al. [2] designed the mechanical hydraulic jack. In this work, it represented the modification of the hydraulics jack, where two cylinders are connected and for the one cylinder the force is applied, if this process is executed then the equal pressure is generated in both the cylinder. With the large are of one cylinder the force produces in that area will be higher, although the force produced by these two cylinders will remain same. Two principles that hydraulic jack depends on: to move oil through cylinders they use plungers pump. And hence the plunger process is involved.

In paper, Mithil et al. [3] designed the fabrication of electrohydraulic jack. The paper describes mainly the conversion of conventional hydraulic jack into automatic hydraulic using linkage mechanism with the help of the motor. Without the application of impact force, the vehicles can be lifted. The authors used the principle of Pascal force the invention relates hydraulic jack and also specified that to the automobile jack system.

Implementation

Block diagram (Figure 2)

electrical-electronic-systems-representation

Figure 2: Block diagram representation.

Functional requirement:

a) Arduino UNO

b) Motors

c) Bluetooth module

d) Switches

e) Battery

f) Driver circuit

a) Arduino UNO: Arduino Uno is used to writing and upload computer code to the physical board here Arduino does not require a separate piece of hardware in order to load new code onto the board instead a USB cable is used also a simple c++ program is dumped onto the hardware.

b) Motors: In the case of our project model we have used two dc servomotors. When current flows through the windings of the armature it sets up a magnetic field opposing the field set up by the magnets this produces a torque on the rotor as the rotor rotates the brush and commutator assemblies switch the current to the armature so that the field remains opposed to the one set up by the magnets which result in the horizontal movement of jack and also the opening, closing movement of jack.

c) Bluetooth module: Here we have used Bluetooth for pairing the device with Arduino and then controlling the jack through navigation buttons present on the interface of the app by sending control signals via Arduino. Bluetooth is a wireless technology standard for exchanging data over short distances using short-wavelength UHF radio waves in the ISM band from 2.4 to 2.485 GHz.

d) Switches: Switch is used to indicate whether the power supply is on or off when the switch is turned on power is directly supplied from the battery for the circuit to function and when the switch is off there is no supply.

e) Battery: As the electric scissor jack runs on a 12 v battery so we have used a 12 v rechargeable battery which gets fully charged in 4 h. About the battery, it is modern SLI batteries which are the lead-acid type and provide 12 v nominally.

f) Driver circuit: Purpose of using a driver circuit is to regulate the current flowing through a circuit and integrated circuit that controls high power switches in switched mode power converters.

App description: We have used an app called smart jack app which is a wireless communication connectivity app which can be installed easily on a phone and after installing app the app is to be opened and Bluetooth has to be turned on because the app connects to the Arduino via Bluetooth so when Bluetooth is opened on phone we can find AC- 05 to which the phone is to be paired now about the interface of the app we have two options for operating the app, the first one on the app interface we can find four navigation buttons which are lifted up and release buttons, also for horizontal movement of jack, second option is tilt option so when the phone is tilted accordingly the movements are performed [4-6].

Results and Discussion

Our designed prototype will work as per the objectives. In our proposed prototype the jack has been placed at the center of the chassis itself considering the ground clearance( normal car ground clearance is 170 mm after the jack fixing ground clearance is 130 mm, which is acceptable ground clearance to the Indian roads). The jack is functioning too and pro movements very well on the rail according to our Bluetooth app commands, and also the jack will open and close as per the commands.

Initially the jack will be present at the centre of the chassis and this jack system need to be power up by the 12v battery supply (battery present in car), when the system is on, the Bluetooth of the jack system will trigger on and we need to turn on our mobile Bluetooth in settings, later we should open the android app named ‘BlueStick control’ and there we need to search for the particular Bluetooth name then pair with it. In our android app, there are two modes for commanding those are 1) BUTTON MODE (where in u can send commands to jack system by pressing buttons), 2) TILT MODE (where in u can send commands to jack system just by tilting the mobile in required direction). Once you select the mode and sends the commands through it, our system will function according to that,

When you press

a. Left arrow – the jack will move towards left

b. Right arrow – the jack will move towards right

c. Down arrow – the jack will open

d. Up arrow – the jack will close

Through these commands, we can place the jack in the required place (which side the flat tire happened) and lift the car (Figure 3). The approach of prototype design is done through the AUTOCAD 360 Software the approach of the 3-D model is designed through this software (Figures 4-6). Figure 3 will show the 3D model of chassis of proposed prototype this 3D model is done using “AUTODESK FUSION 360” software. Jack placed at required place and lifting the car according to commands (Figure 6) [7-12].

Conclusion

This concept can be implemented to all currently manufacture chassis and frame. With the present topology conditions jack movement takes place in the vertical leveling. By the use of car battery which is of 12 V, the sliding movement takes place. The android app can be carried by the user or can be installed/mounted in the dash board of the car for the user convenience. The present innovation, with the torque supplied it is more enough to lift the capacity of 2500 kg.
