It should be noted that the fifth wall panel 20111 and the sixth wall panel are arranged opposite to each other.

[0053] Further, the first shock absorbing member 3 comprises: a connecting rod 303 and a shock absorbing spring 304, and the shock absorbing spring 304 is sleeved and limited on the connecting rod 303 in a slightly compressed state. The first connecting portion 301 is arranged at one end of the connecting rod 303, and the first connecting portion 301 has an annular structure. The first connecting portion 301 is arranged between the first wall plate 1011a and the second wall plate 1011b, and a through hole M is arranged on the first wall plate 1011a, and a limiting hole N is arranged on the second wall plate 1011b. The first connecting portion 301 is coaxially arranged with the through hole M and the limiting hole N so as to penetrate the connecting member 5, so as to realize that the first connecting portion 301 is connected with the first wall plate 1011a and the second wall plate 1011b by the connecting member 5, so as to complete the connection between the first shock absorbing member 3 and the frame 1. Preferably, the through hole M on the first wall plate 1011a is a circular hole, and the limiting hole N on the second wall plate 1011b is a rectangular hole.

[0054] The second connection part 302 is arranged at the other end of the connecting rod 303, and the second connection part 302 has an annular structure. The fifth wall plate 20111 also has a limiting hole N, and the limiting hole N can be coaxially arranged with the second connection part 302, so that the limiting hole N on the fifth wall plate 20111 is directly opposite to and connected with the second connection part 302, so as to penetrate another connecting member 5, and realize that the second connection part 302 is connected to the fifth wall plate 20111 by the connecting member 5, so as to complete the connection between the second shock absorbing member 4 and the rear fork 2. Preferably, the limiting hole N on the fifth wall plate 20111 is also a rectangular hole.

[0055] Furthermore, the structure of the second shock absorbing member 4 is the same as that of the first shock absorbing member 3. Figures 1 to 5 As shown, the connection mode between the third connection portion of the second shock absorbing member 4 and the second fixing portion 1021, and the connection mode between the fourth connection portion of the second shock absorbing member 4 and the sixth wall plate on the fourth fixing portion 2021 can refer to the specific description between the first shock absorbing member 3 and the frame 1 and the rear fork 2, which can be fully understood by those skilled in the art, and the same or similar contents will not be repeated. Similarly, a limit hole N is also provided on the sixth wall plate.

[0056] Preferably, the first wall panel 1011a, the second wall panel 1011b, the third wall panel and the fourth wall panel have the same thickness, and the thickness of the above four wall panels is preferably 2.5 mm. The fifth wall panel 20111 and the sixth wall panel have the same thickness, preferably 4 mm. The first shock absorbing component 3 and the first fixing portion 1011 are connected by a double-wall panel, and the first shock absorbing component 3 and the third fixing portion 2011 are connected by a single-wall panel. By thickening the thickness of the fifth wall panel 20111, the connection strength between the first shock absorbing component 3 and the rear fork 2 can be strengthened. At the same time, on the basis of ensuring the connection strength between the first shock absorbing component 3 and the frame 1, the first wall panel 1011a and the second wall panel 1011b are appropriately thinned, which helps to reduce the overall weight of the frame 1.

[0057] The second shock absorbing member 4 is similar to the frame 1 and the rear fork 2 .

[0058] Furthermore, the connecting member 5 includes: a fastener 501, an end cap 502, an anti-loosening ring 505 and a locking member 504, wherein the fastener 501 is specifically a bolt, the end cap 502 is a nut arranged at one end of the bolt, the locking member 504 is an anti-loosening nut that can be adapted to be connected or disassembled with the bolt, the anti-loosening ring 505 is arranged on the side of the locking member 504 facing away from the end cap 502, the anti-loosening ring 505 and the locking member 504 have an integral structure, and a washer is arranged in the anti-loosening ring 505, which can increase the stability between the locking member 504 and the fastener 501.

[0059] Furthermore, a limiting portion 503 is provided on the fastener 501. The limiting portion 503 is provided on the side of the end cap 502 facing the fastener 501. The limiting portion 503 is raised relative to the surface of the end cap 502. The limiting portion 503 is located between the end cap 502 and the fastener 501 and is provided around the fastener 501. Preferably, the end cap 502, the fastener 501 and the limiting portion 503 have an integrated structure. More preferably, the limiting portion 503 is square.

[0060] Furthermore, the shock absorbing structure of the two-wheeled electric vehicle further comprises a gasket 6 , which is sleeved on the fastener 501 , and the locking member 504 is on the side away from the anti-loosening ring 505 .

[0061] When using the connecting member 5 to connect the first connecting part 301 and the second fixing part 1021, the fastener 501 is sequentially passed through the limiting hole N on the second wall plate 1011b and the circular hole on the first wall plate 1011a, so that the end cap 502 fits against the outer wall surface of the second wall plate 1011b, and the limiting part 503 is clamped in the limiting hole N to ensure that the fastener 501 cannot rotate, and then a gasket 6 is sleeved on the end of the fastener 501 located on the outer side of the first wall plate 1011a, and finally the locking member 504 is used to lock it. As the locking member 504 is continuously rotated, the locking member 504 can contact with the gasket 6 and continue to squeeze the gasket 6. By setting the gasket 6, the contact area between the locking member 504 and the gasket 6 can be increased, the locking strength of the locking member 504 can be increased, and the locking member 504 can be prevented from loosening due to factors such as bumps and vibrations.

[0062] In addition, it should be noted that when the fastener 501 is assembled, the limit portion 503 is first clamped in the limit hole N, which has an anti-rotation effect. Therefore, when the locking member 504 is subsequently screwed, the locking member 504 can be manually assembled, and the connection and locking of the connecting component 5 can be completed without tools such as wrenches. The operation is simple, not affected by the environment, and can be conveniently operated outdoors.

[0063] At the same time, since the limiting portion 503 is clamped in the limiting hole N, the rotation of the fastener 501 due to factors such as bumps and vibrations is also reduced. It can be seen that the shock-absorbing structure of the two-wheeled electric vehicle provided in the present application can improve the connection strength and connection stability of the first shock-absorbing component 3 and the second shock-absorbing component 4 from two aspects of preventing the locking member 504 from loosening and the fastener 501 from loosening.

[0064] The connection process of the second shock absorbing member 4 and the frame 1 with other connecting members 5, the connection process of the first shock absorbing member 3 and the rear fork 2, and the connection process of the second shock absorbing member 4 and the rear fork 2 can refer to the above content, which can be fully understood by those skilled in the art and will not be elaborated here.

[0065] It should be noted that the above-mentioned limiting hole N is adapted to the shape of the limiting portion 503 and is also square. Preferably, the side length of the limiting hole N is preferably 10.2 mm. Preferably, the height of the limiting portion 503 is 2.3-2.5 mm, and the side length of the limiting portion 503 is preferably 10-10.1 mm, so as to ensure that the limiting portion 503 can be embedded in the limiting hole N, and at the same time, the limiting portion 503 will not interfere with the connection of the fastener 501.

[0066] To sum up, the shock-absorbing structure of the two-wheeled electric vehicle provided in the present application, by setting a connecting member 5, the connecting member 5 respectively completes the connection between the first shock-absorbing member 3, the second shock-absorbing member 4 and the frame 1 and the rear fork 2, which can effectively ensure the connection strength and connection stability of the first shock-absorbing member 3 and the second shock-absorbing member 4, and reduce the probability of the first shock-absorbing member 3 and / or the second shock-absorbing member 4 becoming loose.

[0067] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit it. Although the present application has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents.
