M279520 八、新型說明： 【新型所屬之技術領域】 本創作係有關一種避震器，特別是一種可以調整車體高度之避震 器。 【先前技術】 為了提高搭乘汽車時的舒適性，通常都會在汽車底盤及輪胎間 B 加裝避震器，以降低汽車震動時的程度。第一 A圖顯示傳統汽車避 震器的示意圖。於車胎懸臂13的伸縮桿17上設有一固定扣環11， 且伸縮桿17上段設有一外套15,其頂端設有一可鎖固於汽車底盤 的脱套16 ;在固定扣環11與聣套16之間撐著一壓縮彈簧10，藉 著利用壓縮彈簧的回復力來使伸縮桿17可以在外套15内伸縮，以 達到緩衝避震之目的。 由於某些特殊的需求（如改裝賽車），必須將汽車本身的高度降低 以降低風阻，如此汽車就需要進行底盤高度的調整，傳統的調整高度 方式，係如第一 A圖和第一 B圖所示。首先在伸縮桿17的下段形成 一環槽12，並於環槽12上固設一扣環11A，接著配合壓縮彈簧10 作用力及長度的影響，如此即可將汽車底盤向下調整，達到調整汽車 高度之目的。然而，像這樣的調整結構，對使用者存在很多不方便和 困擾。例如： M279520 1.調整範圍有限 由於調整時需要先在伸縮桿17上形成環槽12 ，然考慮到環槽 12間強度及環槽12寬度的實際需求，並沒有辦法進行無段式的調 整；再加上伸縮桿17的上段設有壓縮彈簧10 ，一般人及工具無法 在這些部位形成環槽，所以只能在伸縮桿10的下段少數地方形成環 槽，所以可以調整的範圍非常有限。 φ 2.調整操作不易 由於避震器是用來連接在底盤和輪胎之間，如果每次調整避震器 時都要拆解整個底盤和輪胎，對操作者而言是非常大的負擔。因此一 般工作人員並不會去拆解避震器來調整，而是直接在伸縮桿17上形 成環槽12及扣環11來調整，如此不僅無法準確的調整到正確的位 置，同時在操作上也極為不便；且由於環槽12是屬於破壞性加工， 一旦出現錯誤就無法修改，對加工者而言是一大挑戰。 3.無法調整緩衝力 由於避震器上面並沒有適當的設計，因此當使用者改變環扣位置 時，整個底盤會跟著一起改變高度，而無法調整壓縮彈簧20的緩衝 避震效果，所以很難滿足一般使用者的需求。 鑑於上述的說明，現有的車子在高度調節上明顯存在著調整不 易，可調性差和調整範圍小等問題，會造成工作人員在調整及維 M279520 修上的不便，無形中提高了成本，降低經濟效益，所以有必要做 進一步的改良。 【新型内容】 為了改善先前技術的缺點，使車子能夠方便的調整高度，本創 作的主要目的在於解決現有的車子在高度調節上明顯存在調整不易， 可調性差和調整範圍小等問題。 本創作的另一目的在讓駕駛者不需要下車、拆解車體即可以調 整避震器的高度，只要扳動開關即可進行車高的調整，且提供無段式 的調整。 為了達到上述目的，本創作提供了一種新型的避震器裝置，其主要包含避 震器，以及固設於避震器上方的氣壓缸；此氣壓缸之頂端則承載及連接於 汽車之車體。空壓機將空氣灌進空氣儲存槽時，會將空氣儲存在空 氣儲存槽中。控制電磁閥組以打開空氣儲存槽到氣壓缸之間的閥 門，讓空氣灌進氣壓缸内，當氣壓缸的體積增大時，車體即被抬高。 控制電磁閥組以打開氣壓缸對外的閥門，讓該氣壓缸内的空氣排 出，當氣壓缸的體積減少時，車體的高度即會降低。 【實施方式】 第二圖顯示本創作實施例之系統功能方塊圖，其提供一種可用 以調整車子高度之裝置。本創作主要包含一氣壓缸21、一開關22、 M279520 空 25 壓機25 ;其中，開關22、 係用以控制氣壓缸21的伸 一電池閥組23、一空氣儲存槽24和一 電池閥組23、空氣儲存槽24和空壓機 縮，使得車身得以調高及回復。 在本實施财，電磁_23包含二電則 控制空氣儲存槽到氣壓缸21之間的閥 二雜 丁广日]阀Π田第一電磁閥打開時，第-兩# A a 當第-電磁g —4閥會Μ ;相反的， 田弟$磁閥關閉時，第二電磁閥會打開。 當開關22被調整到某一狀態時，第一 包磁閥打開，而第二電磁 =閉’㈣，空氣會經由空氣儲存槽24而灌進氣壓，使 ==梅料㈣以，進_車體的高㈣力"當開關 ^ °』'狀怨時，第-電磁閥關閉，第二電磁閥打開，此時， ::缸21因受車體重量之壓力’而將其内部的空氣排擠出，因而使 付乳昼缸21的體積和高度減少，進而使得車體的高度又回復 的高度。 ” 第- Α圖和第二Β圖顯示本創作實施例中避震器和氣壓缸之爆 、令刀解圖伸縮才于37藉由螺絲31h固定於車胎懸臂33，另外，伸 縮桿37上固設有-固以口環31。伸縮桿37的上段設有—外套％其 M279520 外撐著一壓縮彈簧30,可以藉由壓 弹貫3〇的回復力來使伸縮桿37 可以在外套35内伸縮，以達到緩 辰之目的。軋壓缸的組成主要 包含塾片31a、墊片31f、〇環3lb ^ 衣 31c、0 環 31d、套筒 31e、 螺絲31g、環狀空氣轨道38、氣 孔㈣第一（外）部份39a 第二（内）部份39b，氣壓缸的 以缸 一 甲間如由一中心桿3b穿過。冬处 氣經由排氣口 3a灌進和排出時，翁 ⑨壓㈣二部份39b内壁上的空氣 轨道38可以讓氣壓紅的受力更 孔 環㈣則可以防止空氣的㈣。^%311^環仏、〇 第四A圖和第四B圖分別顯示組合後的氣心於 體積變化情形。於第四八圖中 减排乳之 口 Y工虱由排氣孔3a進入，經由处裔私 道38將氣壓缸第一部份3 ； 他和乳壓叙第二部份39b撐 其體積和高度都增加，進 使M279520 8. Description of the new type: [Technical field to which the new type belongs] This creation relates to a shock absorber, especially a shock absorber that can adjust the height of the vehicle body. [Previous technology] In order to improve the comfort when riding a car, a shock absorber is usually installed between the chassis and the tire B of the car to reduce the degree of car vibration. The first diagram A shows a schematic diagram of a conventional automobile shock absorber. A fixed buckle 11 is provided on the telescopic rod 17 of the cantilever 13 of the tire, and an outer sleeve 15 is provided on the upper part of the telescopic rod 17, and a top sleeve 16 for locking the car chassis is provided at the top; A compression spring 10 is supported therebetween, and by using the restoring force of the compression spring, the telescopic rod 17 can be expanded and contracted in the outer casing 15 to achieve the purpose of buffering and absorbing shock. Due to some special requirements (such as modified racing cars), the height of the car itself must be lowered to reduce wind resistance, so the car needs to adjust the height of the chassis. The traditional method of adjusting the height is shown in Figures A and B. As shown. Firstly, a ring groove 12 is formed in the lower section of the telescopic rod 17, and a retaining ring 11A is fixed on the ring groove 12, and then the effect of the force and length of the compression spring 10 is adjusted, so that the chassis of the car can be adjusted downward to adjust the car. The purpose of height. However, the adjustment structure like this has a lot of inconvenience and trouble for the user. For example: M279520 1. The adjustment range is limited. Because the ring grooves 12 need to be formed on the telescopic rod 17 before adjustment, but considering the actual requirements of the strength between the ring grooves 12 and the width of the ring grooves 12, there is no way to perform stepless adjustment; In addition, the upper part of the telescopic rod 17 is provided with a compression spring 10, and ordinary people and tools cannot form ring grooves in these parts, so only a few places can be formed in the lower section of the telescopic rod 10, so the range of adjustment is very limited. φ 2. The adjustment operation is not easy Since the shock absorber is used to connect between the chassis and the tire, if the entire chassis and tire are disassembled every time the shock absorber is adjusted, it is a very heavy burden for the operator. Therefore, the general staff will not disassemble the shock absorber for adjustment, but directly form a ring groove 12 and a retaining ring 11 on the telescopic rod 17 for adjustment, so that not only cannot be accurately adjusted to the correct position, but also in operation It is also extremely inconvenient; and because the ring groove 12 is a destructive process, once an error occurs, it cannot be modified, which is a big challenge for the processor. 3. Unable to adjust the cushioning force. There is no proper design on the shock absorber, so when the user changes the position of the ring, the entire chassis will change along with it, and the cushioning and shock-absorbing effect of the compression spring 20 cannot be adjusted. Meet the needs of general users. In view of the above description, the existing vehicles have obvious problems in height adjustment, poor adjustability, and small adjustment range, which will cause inconvenience for staff to adjust and maintain M279520, which will increase costs and reduce economics. Benefits, so it is necessary to make further improvements. [New content] In order to improve the shortcomings of the prior art and enable the vehicle to adjust the height conveniently, the main purpose of this creation is to solve the problems of existing vehicles that are obviously difficult to adjust in height adjustment, poor adjustability and small adjustment range. Another purpose of this creation is to allow the driver to adjust the height of the shock absorber without getting off the vehicle and disassembling the vehicle body. The vehicle height can be adjusted as long as the switch is moved, and stepless adjustment is provided. In order to achieve the above purpose, this creation provides a new type of shock absorber device, which mainly includes a shock absorber and a pneumatic cylinder fixed above the shock absorber; the top of this pneumatic cylinder carries and is connected to the car body . When the compressor fills air into the air storage tank, it stores the air in the air storage tank. The solenoid valve group is controlled to open the valve between the air storage tank and the pneumatic cylinder to allow air to be filled into the pressure cylinder. When the volume of the pneumatic cylinder increases, the car body is lifted. The solenoid valve group is controlled to open the external valve of the pneumatic cylinder to allow the air in the pneumatic cylinder to be discharged. When the volume of the pneumatic cylinder is reduced, the height of the vehicle body is reduced. [Embodiment] The second figure shows a functional block diagram of the system of this creative embodiment, which provides a device that can be used to adjust the height of the car. This creation mainly includes a pneumatic cylinder 21, a switch 22, an M279520 air 25 compressor 25; among them, the switch 22 is used to control a pneumatic cylinder 21 to extend a battery valve group 23, an air storage tank 24, and a battery valve group 23 The air storage tank 24 and the air compressor are retracted, so that the body can be adjusted up and back. In this implementation, electromagnetic_23 includes Erdian, which controls the valve between the air storage tank and the pneumatic cylinder 21. When the first solenoid valve is opened, the second-## a a The g-4 valve will be M; conversely, when the Tiandi $ solenoid valve is closed, the second solenoid valve will be opened. When the switch 22 is adjusted to a certain state, the first package magnetic valve is opened, and the second solenoid = closed, the air will be filled with the intake pressure through the air storage tank 24, so that == plum material, enter the car The high pressure of the body " When the switch ^ ° `` ', the first-solenoid valve is closed and the second solenoid valve is opened, at this time, :: cylinder 21 is under the pressure of the weight of the vehicle body and the air inside it The row is squeezed out, so that the volume and height of the daytime feeding cylinder 21 are reduced, and the height of the vehicle body is restored again. Figures-A and 2B show the explosion of the shock absorber and the pneumatic cylinder in this creative embodiment, and the knife was retracted and fixed to the tire cantilever 33 by screws 31h. In addition, the telescopic rod 37 is fixed on It is provided with-fixed to the mouth ring 31. The upper section of the telescopic rod 37 is provided with an outer jacket. Its M279520 supports a compression spring 30 outside, and the telescopic rod 37 can be made in the outer casing 35 by pressing the restoring force of 30%. Retractable to achieve the purpose of slowing down. The composition of the rolling cylinder mainly includes the cymbal 31a, gasket 31f, 0 ring 3lb ^ clothing 31c, 0 ring 31d, sleeve 31e, screw 31g, annular air track 38, air hole The first (outer) part 39a and the second (inner) part 39b. The cylinder and the first part of the pneumatic cylinder pass through a center rod 3b. When the air in the winter is filled and discharged through the exhaust port 3a, The air track 38 on the inner wall of the second part 39b can make the pressure of the pressure red more porous, and can prevent the air from ㈣. ^% 311 仏 ring, the fourth picture A and the fourth picture B respectively show the combination Qi ’s enthusiasm for the volume change. In the 48th figure, the mouth of the mitigation milk Y lice entered through the exhaust hole 3a, and passed through the descent. The private channel 38 supports the first part 3 of the pneumatic cylinder; he and the second part 39b of the milk pressure support both increase the volume and height of the cylinder.
