The engaging piece 43 (only one is shown in FIG. 5 and FIG. 6 due to the angle of view). Each adjusting piece 42 extends from the fixing piece 41 toward the lower frame 21 , and forms a plurality of positioning holes 420 which are spaced apart from each other. Each engaging piece 43 is fixed on the second rod portion 312 of the corresponding suspension arm 31 , and detachably passes through one of the positioning holes 420 of the corresponding adjusting piece 42 , so that Each suspension arm 31 is positioned on the anti-tilting unit 4 to prevent the rear wheel 11 from tilting due to force during driving. It should be noted that, each engaging member 43 is inserted through different positioning holes 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 needs 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 FIG. 7 and FIG. 8 and in conjunction with FIG. 3 , define two auxiliary lines L1 that respectively pass through the joints between the body parts 321 and the suspension arms 31 and are respectively perpendicular to the upper frames 22 . Since one end of the body 321 of each shock absorber 32 is positioned on the corresponding suspension arm 31, and the second adjusting portion 322 can move back and forth in the corresponding through slot 220, the The shock-absorbing components 32 can swing back and forth relative to the suspension arms 31 , and are locked and positioned on the upper frames 22 by the locking members 33 . Referring to FIGS. 9 and 10 in conjunction with FIG. 8 , each shock absorber assembly 32 can adjust the inclination angle between the auxiliary line L1 and the auxiliary line L1 according to different load requirements. In this embodiment, an extension axis L2 of each body portion 321 An included angle θ formed with the corresponding auxiliary line L1 is 0 to 10 degrees, thereby generating different suspension hard points. For example, when each shock absorber 32 is located at the position shown in FIG. 9 , the extension axis L2 is tilted toward the lower frame 21 , and the included angle θ is 10 degrees, at this time, the suspension hard point is higher Therefore, it can meet the high load requirements, so that this embodiment can be applied to transportation, freight home delivery or rescue, etc. When each shock absorber assembly 32 is in the position shown in FIG. The direction is tilted, and the included angle θ is 10 degrees. At this time, the suspension hard point is lower and can be used for single-person driving with lower load requirements; when each shock absorber assembly 32 is located at the position shown in FIG. 8, the extension The axis L2 is located on the auxiliary line L1 to generate a relatively moderate suspension hard point, so that it can be used in urban connection, shared transportation, and the like. Therefore, when the present embodiment is assembled in a car factory, the relative position between each shock absorber assembly 32 and the frame unit 2 can be adjusted according to different load requirements and operating conditions, and then the corresponding The locking member 33 is used to complete 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 depot can still flexibly adjust the suspension unit 3 in the same mobile vehicle In order to achieve the effect of high adaptability, the adjustment steps are relatively simple, and additional production lines are not required to manufacture suspension devices with different suspension hard points, thus saving 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 FIG. 3 and FIG. 4 again, the suspension arms 31 are arranged independently of each other, and the structure is simple and occupies less space in the vehicle body, so it can meet the requirements of the miniature electric vehicle. The design of each spring 323 sleeved on the body 321 can not only reduce the space occupied by the vehicle body, but also swing together with the body 321 to offset the effect of weight load at different suspension hard points. In addition, referring to FIGS. 5 and 6 again, since the anti-tilt unit 4 can be used to fix the relative positions of the suspension arms 31 , the rear wheels 11 can be prevented from being tilted during driving, and the rear wheels 11 can be lifted. The contact area of the rear wheel 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。To sum up, the adjustable suspension device of the present invention can move within the through grooves 220 through the shock-absorbing components 32 respectively, thereby changing the mechanism of the suspension hard point, so that the same type of mobile vehicle can be used for different It can be adjusted according to the load requirements to obtain better vehicle body maneuverability. In addition, the suspension arms 31 are suitable for light-duty electric vehicles because of their small footprint and light weight, and are restricted by the anti-tilt unit 4 to prevent the rear wheels 11 from skewing during driving. And it can increase the contact area with the ground to increase the frictional force and achieve the effect of safe driving, so it can indeed achieve the purpose of the present 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 limit the scope of the present invention. Any simple equivalent changes and modifications made according to the scope of the application for patent of the present invention and the content of the patent specification are still within the scope of the present invention. within the scope of the invention patent.
