本發明是有關於一種懸吊裝置，特別是指一種可調式懸吊裝置。 The invention relates to a suspension device, in particular to an adjustable suspension device.

近年來，城市內短程移動例如送貨、老年代步等的需求越來愈高，其中，微型電動車受到世界各地的都會通勤人士喜愛，而逐漸成為一大商機，使得許多車廠開始生產微型四輪電動車。參閱圖1，為一種習知的懸吊裝置5，包含一車輪51、一連接該車輪51的拖曳臂52、一設置於該拖曳臂52上的減震器53，及一設置於該拖曳臂52且與該減震器53相間隔設置的彈簧54。 In recent years, the demand for short-distance mobility in cities, such as delivery, old-fashioning, etc., has become higher and higher. Among them, micro-electric vehicles are loved by commuters from all over the world, and have gradually become a big business opportunity, making many car manufacturers begin to produce micro-four-wheels. Electric car. 1, it is a conventional suspension device 5, including a wheel 51, a trailing arm 52 connected to the wheel 51, a shock absorber 53 arranged on the trailing arm 52, and a trailing arm arranged on the trailing arm 52 and a spring 54 arranged spaced apart from the shock absorber 53.

然而，為了符合環保，就必須將電動車做得更輕，以減少耗能，但大部分車廠皆沿用如圖1所示之汽油車輛的懸吊裝置5，而造成該車輪51易歪斜、該拖曳臂52之結構較複雜、該減震器53與該彈簧54佔用空間較大且不易調整等問題，將不利於微型電動車操控。此外，微型電動車的使用者會有不同的懸吊硬點需求，例如貨運宅配、微型搬運等為高負荷需求，或是單人行使、通勤上 班等為低負荷需求，使得車廠必須配合不同需求而開發不同的懸吊結構，導致成本上升，因此上述缺失有待改善。 However, in order to comply with environmental protection, electric vehicles must be made lighter to reduce energy consumption. However, most car manufacturers still use the suspension device 5 of gasoline vehicles as shown in Figure 1, which causes the wheels 51 to be skewed and the The structure of the trailing arm 52 is relatively complex, the shock absorber 53 and the spring 54 occupy a large space and are difficult to adjust, which are not conducive to the control of the micro-electric vehicle. In addition, users of micro-electric vehicles have different suspension requirements, such as high-load requirements such as freight home delivery and micro-transportation, or single-person exercise and commuting. Due to the low-load demand of shifts, car manufacturers must develop different suspension structures to meet different needs, leading to increased costs. Therefore, the above-mentioned shortcomings need to be improved.

因此，本發明之目的，即在提供一種可針對不同需求而進行調整的可調式懸吊裝置。 Therefore, the purpose of the present invention is to provide an adjustable suspension device that can be adjusted for different needs.

In particular, it should be noted that each engaging member 43 is inserted through a different positioning hole 420, which will change the corresponding position between the suspension arm 31 and the adjusting member 42, thereby producing different positioning effects to meet different requirements. Demand.

特別需要說明的是，參閱圖7與圖8並配合圖3，定義二分別通過該等身部321與該等懸吊臂31間之連接處，並分別垂直該等上框架22的輔助線L1。由於每一避震組件32的該身部321之一端定位於相對應之該懸吊臂31上，而該第二調整部322能在相對應之該通槽220內前後移動的機制，使得該等避震組件32能相對於該等懸吊臂31前後擺動，並經由該等鎖固件33鎖固而定位於該等上框架22。參閱圖9與圖10並配合圖8，每一避震組件32能對應不同負荷需求而調整與該輔助線L1之間的傾斜角度，在本實施例中，每一身部321之一延伸軸線L2與相對應之該輔助線L1間所形成的一夾角θ為0到10度，藉此產生不同懸吊硬點。舉例來說，當每一避震組件32位於圖9所示的位置時，該延伸軸線L2朝向該下框架21之方向傾倒，而該夾角θ為10度，此時，懸吊硬點較高而能滿足高載重負荷需求，使得該實施例能應用於搬運、貨運宅配或救援等； 當每一避震組件32為於圖10所示的位置時，該延伸軸線L2朝向該延伸框架23之方向傾倒，而該夾角θ為10度，此時，懸吊硬點較低而能配合負載需求較低的單人行駛；當每一避震組件32位於圖8所示的位置時，該延伸軸線L2位於該輔助線L1上而產生較適中的懸吊硬點，以至於能應用在城市接駁、共享交通等。因此，本實施例在車廠組裝時，能根據不同的載重需求及使用工況，來調整每一避震組件32與該車架單元2間的相對位置，再透過組裝人員鎖固相對應之該鎖固件33來完成定位，也就是說，藉由本實施例中能調整懸吊硬點的機制，即使是針對不同使用狀況，車廠依然能在同款移動載具中彈性地調整該懸吊單元3的設定，以達到高適應性的功效，且調整步驟較簡單，也不需要額外生產線來製造不同懸吊硬點的懸吊裝置，因而能省下大量的生產成本。 It should be noted that, referring to FIGS. 7 and 8 in conjunction with FIG. 3, definition two respectively pass through the connection between the bodies 321 and the suspension arms 31, and are respectively perpendicular to the auxiliary lines L1 of the upper frames 22. Since one end of the body portion 321 of each shock-absorbing component 32 is positioned on the corresponding suspension arm 31, and the second adjustment portion 322 can move back and forth in the corresponding through slot 220, the mechanism The shock-absorbing components 32 can swing back and forth relative to the suspension arms 31, and are locked by the locking members 33 to be positioned on the upper frames 22. Referring to FIGS. 9 and 10 in conjunction with FIG. 8, each shock-absorbing component 32 can adjust the inclination angle with the auxiliary line L1 in response to different load requirements. In this embodiment, each body 321 extends an axis L2 An included angle θ formed between the corresponding auxiliary line L1 is 0 to 10 degrees, thereby generating different suspension hard points. For example, when each shock-absorbing component 32 is at the position shown in FIG. 9, the extension axis L2 tilts toward the direction of the lower frame 21, and the included angle θ is 10 degrees. At this time, the suspension hard point is higher. It can meet the demand of high load, so that this embodiment can be applied to transportation, freight home delivery or rescue, etc.; When each shock-absorbing component 32 is in the position shown in FIG. 10, the extension axis L2 tilts toward the extension frame 23, and the included angle θ is 10 degrees. At this time, the suspension rigidity is low and can be matched. Single-person driving with a lower load demand; when each suspension assembly 32 is located at the position shown in FIG. 8, the extension axis L2 is located on the auxiliary line L1, resulting in a moderate suspension hard point, so that it can be used in City connection, shared transportation, etc. Therefore, when this embodiment is assembled in a car factory, the relative position between each shock absorber component 32 and the frame unit 2 can be adjusted according to different load requirements and operating conditions, and then the corresponding position can be locked by the assembler. The locking member 33 completes the positioning. That is to say, with the mechanism that can adjust the suspension hard point in this embodiment, even for different usage conditions, the car manufacturer can still flexibly adjust the suspension unit 3 in the same mobile vehicle. To achieve highly adaptable effects, and the adjustment steps are relatively simple, and no additional production line is needed to manufacture suspension devices with different suspension hard points, which can save a lot of production costs.

另外需要說明的是，重新參閱圖3與圖4，該等懸吊臂31彼此獨立設置，且結構較簡單而佔用車身空間較小，故能符合微型電動車的需求。每一彈簧323套設於該身部321的設計，不僅能減少占用車身空間，還能一同與該身部321擺動，在不同懸吊硬點之位置抵銷重量負載的功效。此外，重新參閱圖5與圖6，由於該防傾斜單元4能用來固定該等懸吊臂31的相對位置，能藉此防止該等後車輪11在行駛過程中歪斜，並能提升該等後車輪11在過彎時的接觸面積，進而增加抓地力及安全性。 In addition, it should be noted that, referring to FIGS. 3 and 4 again, the suspension arms 31 are arranged independently of each other, and have a simple structure and occupy less space in the vehicle body, so they can meet the requirements of a miniature electric vehicle. The design of each spring 323 sleeved on the body 321 not only reduces the space occupied by the body, but also oscillates with the body 321 together to offset the effect of weight load at different suspension hard points. In addition, referring again to Figures 5 and 6, since the anti-tilt unit 4 can be used to fix the relative positions of the suspension arms 31, it can prevent the rear wheels 11 from skewing during driving and can lift the The contact area of the rear wheels 11 when cornering, thereby increasing the grip and safety.

綜上所述，本發明可調式懸吊裝置透過該等避震組件32能分別在該等通槽220內移動，藉此改變懸吊硬點的機制，使得同款移動載具能針對不同的載重需求而調整，以獲得較佳的車體操作性。此外，該等懸吊臂31之佔車空間小、重量較輕而適用於輕型電動車，且受到該防傾斜單元4的限制，能避免該等後車輪11在行駛過程中歪斜的狀況發生，並能提升與地接觸的面積而增加摩擦力，達到安全行駛的功效，故確實能達成本發明之目的。 In summary, the adjustable suspension device of the present invention can be moved in the through slots 220 through the shock-absorbing components 32, thereby changing the mechanism of the suspension hard point, so that the same mobile vehicle can target different Adjust according to load demand to obtain better car body maneuverability. In addition, the suspension arms 31 have small vehicle space and light weight, and are suitable for light electric vehicles, and are restricted by the anti-tilt unit 4, which can prevent the rear wheels 11 from skewing during driving. And it can increase the area of contact with the ground to increase friction, and achieve the effect of safe driving, so it can indeed achieve the purpose of the invention.

惟以上所述者，僅為本發明之實施例而已，當不能以此限定本發明實施之範圍，凡是依本發明申請專利範圍及專利說明書內容所作之簡單的等效變化與修飾，皆仍屬本發明專利涵蓋之範圍內。 However, the above are only examples of the present invention, and should not be used to limit the scope of implementation of the present invention, all simple equivalent changes and modifications made in accordance with the scope of the patent application of the present invention and the content of the patent specification still belong to This invention patent covers the scope.
