Obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the utility model.

[0023] Reference Figures 1-5 A battery front-mounted electric bicycle frame of anti-impact, including oblique battery support frame 1, the inside of oblique battery support frame 1 is provided with detachable portable battery 6, both ends of oblique battery support frame 1 are provided with lateral anti-collision column 4, oblique battery support frame 1 and lateral anti-collision column 4 are fixed with support cabin 5, the top of oblique battery support frame 1 is rotatably connected with L-shaped rotating part 3, the top of L-shaped rotating part 3 is fixed with head mounting pipe 2, the bottom of oblique battery support frame 1 is provided with buffer mechanism for buffering head mounting pipe 2;

[0024] The inside of support cabin 5 is provided with support assembly;

[0025] The buffer mechanism includes first circular plate 8 and second circular plate 9, oil cylinder 10 is arranged between first circular plate 8 and second circular plate 9, rigid spring 11 is arranged between first circular plate 8 and second circular plate 9 and outside oil cylinder 10, the bottom of first circular plate 8 is rotatably connected with transverse support column 7 through pin shaft, one end of transverse support column 7 close to oblique battery support frame 1 is fixedly connected with oblique battery support frame 1, the top of second circular plate 9 is rotatably connected with L-shaped rotating part 3 through pin shaft;

[0026] The inside of the L-shaped rotating piece 3 is fixed with a longitudinal rotating column 12, which is located inside the inclined battery support frame 1 and is rotationally connected with the inclined battery support frame 1 through a bearing. The longitudinal rotating column 12 is arranged to enable the L-shaped rotating piece 3 to rotate around the longitudinal rotating column 12, so that when the front wheel of the electric vehicle is impacted, the front wheel can be buffered, and the buffering performance of the electric bicycle frame is improved.

[0027] When the wheel is impacted, the L-shaped rotating piece 3 can rotate around the longitudinal rotating column 12, and the spacing between the first circular plate 8 and the second circular plate 9 can be changed through the rotation of the L-shaped rotating piece 3. The oil cylinder 10 and the rigid spring 11 are arranged to enable the wheel to be buffered after being impacted, prevent damage to the vehicle, and improve the anti-impact performance of the device.

[0028] The support assembly includes a buffer pad 13, and the top and bottom of both ends of the inclined battery support frame 1 are fixed with the buffer pad 13. One end of the buffer pad 13 is provided with a rectangular impact plate 14, one end of the rectangular impact plate 14 is provided with a transverse impact column 15, and one end of the transverse impact column 15 is fixed with a circular impact block 16.

[0029] The top and bottom of the support cabin 5 are symmetrically provided with arc-shaped buffer plates 17. The arc-shaped buffer plates 17 are fixedly connected with the inclined battery support frame 1 and the lateral anti-collision column 4.

[0030] The material of the arc-shaped buffer plate 17 is rubber, which is an elastic material that can deform greatly under external force. When subjected to force, rubber will compress or stretch and store a certain amount of elastic potential energy. When the external force is released, the rubber will quickly return to its original shape and release the stored energy. This elastic deformation enables rubber to effectively absorb impact energy and reduce damage to objects.

[0031] The material of the buffer pad 13 is a curved steel strip, which is commonly used in applications that require high impact resistance, support, and durability. The arc-shaped steel strip is made of steel, which has very high strength and rigidity. This enables the arc-shaped steel strip to withstand large impact forces and loads. In anti-collision applications, the rigidity of the steel strip can effectively disperse external impact forces and prevent excessive deformation, ensuring the integrity of the structure. When external force acts on the arc-shaped steel strip, the steel strip will bend to a certain extent to absorb the impact force. The bent steel strip can release the absorbed energy by returning to its original shape, reducing the impact of the impact on the target.

[0032] When the lateral anti-collision column 4 is impacted, the impact force can be effectively reduced by the arrangement of the two arc-shaped buffer plates 17, and the impact on the target is reduced, and when the lateral anti-collision column 4 is impacted to a certain extent, the circular impact block 16 is impacted, the buffer pad 13 can effectively absorb impact energy and reduce damage to the object, thereby improving the anti-impact performance of the lateral anti-collision column 4.

[0033] When the front wheel is impacted or vibrates violently, the impact force can be absorbed and relieved in real time, the vibration is reduced to other parts of the inclined battery support frame 1, the stability and comfort of the vehicle are improved, the lateral bearing capacity of the inclined battery support frame 1 is enhanced, the impact resistance of the lateral anti-collision column 4 in the case of lateral collision is further improved, and the safety of the portable battery 6 and the inclined battery support frame 1 is effectively protected.

[0034] Working principle: when the wheel is impacted, the L-shaped rotating part 3 can rotate around the longitudinal rotating column 12 as the center, the spacing between the first circular plate 8 and the second circular plate 9 can be changed through the rotation of the L-shaped rotating part 3, and through the arrangement of the oil cylinder 10 and the rigid spring 11, the wheel can be buffered after being impacted, and the damage of the vehicle is prevented, so as to facilitate the anti-impact performance of the device.

[0035] When the lateral anti-collision column 4 is impacted, the impact force can be effectively reduced by the arrangement of the two arc-shaped buffer plates 17, and the impact on the target is reduced, and when the lateral anti-collision column 4 is impacted to a certain extent, the circular impact block 16 is impacted, the buffer pad 13 can effectively absorb impact energy and reduce damage to the object, thereby improving the anti-impact performance of the lateral anti-collision column 4.

[0036] Although the embodiments of the utility model have been shown and described, it can be understood by those skilled in the art that various changes, modifications, replacements and variations can be made to these embodiments without departing from the principles and spirits of the utility model, the scope of the utility model is defined by the appended claims and its equivalents.
