[0024] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0025] Embodiment 1

[0026] Please refer to Figures 1 to 7 , the present invention provides a technical solution: an electric bicycle frame structure, including a frame body 1, and a battery installation mechanism 2 is arranged inside the frame body 1;

[0027] The battery installation mechanism 2 includes a battery box assembly 21 arranged inside the frame body 1. A number of equally spaced first springs 22 are installed inside the battery box assembly 21. The top of each first spring 22 is commonly installed with a placing seat 23. Protection pads 24 are arranged around the inner wall of the placing seat 23. The protection pads 24 are made of rubber. Two symmetrically arranged connecting plates 25 are installed at the top of the placing seat 23. Fixed plates 26 are installed at the tops of the two connecting plates 25. Support pillars 27 are installed at the corners around the inside of the placing seat 23. The tops of each support pillar 27 are commonly installed with a bottom plate 28. The battery body 210 is located on the top of the bottom plate 28. A number of ventilation holes 29 are opened inside the bottom plate 28. A number of battery bodies 210 are arranged inside the placing seat 23. The top of the battery box assembly 21 is connected with a box cover 201 by bolts;

[0028] The battery box assembly 21 includes a box body 211 disposed inside the vehicle frame body 1. Two symmetrically arranged grooves 212, notch 213, and sliding grooves 214 are respectively formed at the top of the box body 211. The sliding groove 214 is located at the top of the notch 213. Two symmetrically arranged connecting grooves 215 are formed inside the notch 213. A second spring 216 is installed on one side inside the notch 213. One end of the second spring 216 is provided with a baffle 217. The baffle 217 is slidably connected inside the notch 213. The baffle 217 is located on the top of the fixing plate 26. Connecting blocks 219 are installed on both outer sides of the baffle 217. The connecting blocks 219 are located inside the connecting grooves 215 and are of a sliding connection structure. A push plate 218 is installed on the top of the baffle 217. The push plate 218 is located at the position of the sliding groove 214.

[0029] When the battery body 210 needs to be repaired or replaced, first use tools to remove several groups of bolts, and then remove the box cover 201. At this time, the user holds the two push plates 218 to drive the baffle 217 to move. The baffle 217 moves inside the notch 213 and compresses the second spring 216. When the baffle 217 is completely inside the notch 213, the baffle 217 disengages from the top of the fixing plate 26. At this time, several groups of first springs 22 are not compressed and bounce back upward to reset. The first springs 22 drive several groups of battery bodies 210 arranged inside the placement seat 23 to move upward. When the battery bodies 210 are higher than the inside of the battery box assembly 21, the staff can take out several groups of battery bodies 210 for repair or replacement.

[0030] When the battery body 210 needs to be fixed inside the battery box assembly 21, the staff holds the push plate 218 to place the baffle 217 inside the notch 213, and then presses down the battery body 210 to compress several groups of first springs 22 until the fixing plate 26 is located at the position of the groove 212 and at the bottom of the baffle 217. The staff then releases the push plate 218. At this time, due to the setting of the second spring 216, the baffle 217 bounces back forward, and the baffle 217 is located on the top of the fixing plate 26, so that the fixing plate 26 can be fixed at the position of the groove 212. Then, the box cover 201 can be fixed on the top of the battery box assembly 21 through several groups of bolts.

[0031] Embodiment 2

[0032] As Figures 1 to 7, in the second embodiment, other structures remain unchanged. Different from the first embodiment, the battery body 210 is located at the top of the bottom plate 28. The setting of the support column 27 leaves a certain gap between the battery body 210 and the placement seat 23. Moreover, several groups of ventilation holes 29 are provided inside the bottom plate 28. The setting of this structure facilitates the heat dissipation of the battery body 210. The protective pad 24 is made of rubber material to protect the battery body 210, prevent it from directly hitting the placement seat 23 due to vibration, and reduce the damage to the battery body 210.

[0033] It should be noted that in this article, relational terms such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the term "comprising", "including" or any other variation thereof is intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements not only includes those elements, but also includes other elements not expressly listed, or further includes elements inherent to such process, method, article or device.

[0034] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
