7、汽車千斤頂是用來提高設備所有或車輛進入的空氣的一部分，以便于車輛的維護或故障修理。大多數(shù)人都熟悉的基本汽車千斤頂（手動操作），它包括作為最新汽車的標準設備。愿意更換輪胎的車主都是從前到后等等或者誰可能在春天冬天之前安裝雪地輪胎，并卸下它們需要使用千斤頂執(zhí)行工作[1]。卸下漏氣的輪胎是不是一個非常愉快的經(jīng)歷?，F(xiàn)今，各種汽車千斤頂已經(jīng)開發(fā)了用于從地面抬起汽車。但是，可用千斤頂通常是手動操作的，因此需用戶的大幅的體力。例如在特別的惡劣天氣條件

8、下，千斤頂對老人和殘疾人的使用非常困難[2]。鑒于這種固有的缺點，商用汽車維修及服務站通常配備大型高科技汽車升降機，其中該升降機是通過電供電系統(tǒng)升高和降低[3]。然而，由于其規(guī)模和采購成本高，維護電動力車升降機，這類升降機一般不提供給車主。這種電供便攜式千斤頂不僅能代替通過手動操作千斤頂起重汽車的艱巨任務，而且進一步降低維修汽車所需的時間。當需要修復的道路的側面或其它危險情況下的汽車[4]，這樣的功能特別有利。</p>&

9、lt;p>　　此外，還有報道關于汽車千斤頂而導致幾次嚴重的事故。指定額定托起1000公斤，但是由消費者事務進行的測試顯示，是失敗起重250公斤后的工作和可能千斤頂損壞的時候接近其額定載荷的重量[3]。試驗證明，該千斤頂有低于所承受的準備重量傾向，并且它不符合澳大利亞標準車輛千斤頂?shù)淖钚⌒阅艿囊骩5]。該項目的目的是開發(fā)一個容易操作、安全、能夠輕松提升和下降汽車并不涉及太多體力的汽車千斤頂。</p><p>

19、它會切換開關，然后電源流入電機和第二個繼電器，將直接進入到負極，電機轉動順時針。反之亦然，如果按下黑色按鈕[11]。</p><p><b>　　圖5：開關電路</b></p><p><b>　　結論</b></p><p>　　考慮到在市場上所有可用的千斤頂，這個原型可以通過在功能和設計上進行一些修改得到改善。目標是設

37、with using </p><p>　　internal cigarette lighter power (12volts). The automatic easy car-jack utilizes this power source </p><p>　　to save individuals having to exert any energy. To increase the

41、used to raise all or part of a vehicle into the air in order to </p><p>　　facilitate vehicle maintenances or breakdown repairs. Most people are familiar with the </p><p>　　basic car jack (manual

42、ly operated) and it’s included as standard equipment for most of the new cars. Vehicle owners who would like to rotate their tires themselves either front to </p><p>　　back and so forth or who may install sn

43、ow tires before the winter and remove them in the spring need to use a jack to perform the job [1]. Changing a flat tire is not a very pleasant </p><p>　　experience. Nowadays, a variety of car jacks have bee

44、n developed for lifting an automobile from a ground surface. Available car jacks, however, are typically manually operated and therefore require substantial laborious physical effort on the part of the user. Such jacks p

45、resent difficulties for the elderly and handicapped and are especially disadvantageous under bad weather conditions [2]. In light of such inherent disadvantages, commercial automobile repair and service stations are comm

46、only eq</p><p>　　There also reports on car jacks which lead to a serious number of accidents. A specified jack </p><p>　　purposed to hold up to 1000 kilograms, but tests undertaken by Consumer A

47、ffairs has </p><p>　　revealed that is fails to work after lifting 250 kilograms and may physically break when it </p><p>　　has a weight close to its 1000 kilograms capacity [3]. Tests have prove

48、n that the jack has the propensity to buckle well under the weight it is promoted to withstand, and it doesn’t meet the minimum or performance requirements of the Australian Standard for vehicle jacks [5]. The purpose of

49、 this project is to develop a car jack which is easy to be operated, safe and able lift and lowering the car without involving much physical effort.</p><p>　　THE DEVELOPMENT</p><p>　　Figure 1 sh

50、ows the design of automatic car jacker where: </p><p>　　1. Original Scissor jack </p><p>　　2. Screw shaft </p><p>　　3. Power window motor </p><p>　　4. Pinion </p

52、k. The entire requirement from the drawing is then transform onto the real prototype. It also included a switch buttons system to raise and lowering the jack (Head load). Figure 1, shows the used scissor jack which has b

53、een collected from the junk yard and it still can be used. The scissor jack is the best jacks available in the market. According to Farhad, the pneumatic and hydraulic jack is not safe because usually need main</p>

54、<p>　　to stabilize the scissor jack. It is also good for flat surface when jacking the car [9].</p><p>　　Figure 1. Design from Solidwork</p><p>　　Figure 2.Developed prototype</p>&

55、lt;p>　　Figure 3. Gearing system</p><p>　　MECHANICAL PARTS</p><p>　　The mechanism lifting system was applied on the scissor jack. The scissor jack specific description is it can withstand the

56、maximum load of 850kg which is the best because the </p><p>　　test car for this project is a PERODUA Kancil® (682kg) [10].The test will be detailed explained in the result.No.3 is the motor which the or

57、iginal gear needed to be discarded because no. 4, pinion and no. 5, gear are manufactured using wire EDM cutting machine. All the specification of the gears according to the torque needed to be applied on the system [11]

58、. The gearing system is the crucial thing as it is the lifting mechanism powered from the motor. The torque from the motor will be supplied </p><p>　　By using the wire EDM cutting machine, the operator neede

59、d to insert the drawing that has </p><p>　　been made and then program the machine so it will work. After the no.4 pinion is fabricated, </p><p>　　it is inserted into the slot of the power window

60、 motor and welded. The no.6 frame is fabricated base on the design to hold the motor. It is fabricated using 3mm low carbon metal and then cut using grinder into small pieces according the dimensions [5]. The cut pieces

61、are then welded on the end of the scissor jack and welded together with other pieces as the picture shown.</p><p>　　The welding machine that involved is MIG machine (Metal Inert Gas).No 7 is the stabilizer b

62、ase which is made from the L iron bar [8]. The length of each iron bar is 30cm and then is screwed and welded on the base of the scissor jack. This is to stabilize the scissor jack with increasing of the surface area wil

63、l increase the stability [5]. Moreover, bending machine is also used to bend the cover for the gearing system and bend saw machine is used to cut the raw material for the gear. Fabricated g</p><p>　　Figure 4

64、. Fabricated gear</p><p>　　Base on Figure 5, switch for the scissor jack to be lifted and lowered are controlled by a 2 </p><p>　　buttons switch with ON/OFF. This switch circuit is to make the m

65、otor enabled to rotate clockwise and counter-clockwise without changing the terminal positive and negative. It </p><p>　　is time consumable to change the terminal every time when using this jack, so by using

66、 </p><p>　　this switch, it is more flexible and easier for the user. The switch also contains 2 relays </p><p>　　which will act when a lifting button is press it will actuate one of the relay an

67、d it will rotate </p><p>　　the motor to the desire level. The most important part is that when the button is release it will stop directly. Let say if the red button is pressed, then it will actuated the coi

68、l in relay 1 and then it will change over the switch and supply will flow to the motor and to the second relay which will go directly to negative terminal and the motor will rotate clock-wise. Vice versa, if the black bu

69、tton is pressed [11]</p><p>　　Figure 5: Switch circuit</p><p>　　CONSLUSIONS </p><p>　　Considering all available car jacks in the market, this prototype can be improved by a few modi

70、fications on the features and design. The objectives are to design a car jack that is safe, reliable and able to raise and lower the level, to develop a car jack that is powered by internal car power and automated with b

71、uttons system. Although this car jack was design only on PERODUA Kancil, by using higher torque it is able to lift more loads such as Proton Wira® and Proton Iswara® car. </p><p>　　Acknowledgments
