[0021] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0022] As shown in the figure, a rear-seat battery mounting assembly for an electric bicycle includes a horizontally arranged support frame 1 and a battery mounting frame 2 connected to the upper side of the support frame 1. The battery mounting frame 2 includes a base plate 21, a connecting plate 22, and an upper cover 23. The base plate 21 is slidably snapped onto the support frame 1. The connecting plate 22 is fixed to the upper side of the base plate 21, and both sides of the connecting plate 22 are provided with inverted L-shaped snap-fit ​​strips 221 facing upwards. The upper cover 23 has an inverted U-shaped structure, and the bottom of the left and right sides is fixed to the corresponding outer side wall of the base plate 21. A seat cushion 3 is fixed to the upper side of the upper cover 23 by bolts. In this embodiment, the support frame 1 is fixed to the rear side of the electric bicycle frame above the rear wheel. The battery mounting bracket 2 is slidably snapped onto the upper side of the support frame 1. The battery 5 has a snap-fit ​​edge 51 corresponding to the snap-fit ​​strip 221. The battery 5 is slidably snapped onto the connecting plate 22 through the cooperation of the snap-fit ​​edge 51 and the snap-fit ​​strip 221, so that the battery 5 is installed in the battery mounting bracket 2. This device is installed at the rear seat position of the electric bicycle, which not only realizes the function of the rear seat of the bicycle, but also facilitates the installation and removal of the battery 5, making the function of the rear seat of the electric bicycle more diversified.

[0023] The support frame 1 includes two vertically spaced mounting plates 11. A support plate 12 is fixedly connected to the upper side of the two mounting plates 11. A horizontally penetrating snap-fit ​​groove 13 is provided at the middle of the front end of the support plate 12. The snap-fit ​​groove 13 is opened on the upper surface of the support plate 12. The bottom plate 21 is slidably snapped into the snap-fit ​​groove 13.

[0024] Reinforcing ribs 14 are fixedly connected between the bottom of the support plate 12 and the corresponding mounting plate 11 to enhance the support strength on both sides of the support plate 12.

[0025] The bottom of the base plate 21 has a snap-fit ​​protrusion 211 corresponding to the snap-fit ​​groove 13. L-shaped snap-fit ​​strips 212 are provided downwards on the left and right sides of the base plate 21. The snap-fit ​​protrusion 211 snaps into the snap-fit ​​groove 13, and the left and right ends of the support plate 12 snap into the corresponding snap-fit ​​strips 212. In this embodiment, the snap-fit ​​of the battery mounting bracket 2 onto the support frame 1 is achieved through the engagement of the snap-fit ​​protrusion 211 and the snap-fit ​​groove 13, as well as the engagement of the snap-fit ​​strips 212 and the edges of the support plate 12 on both sides.

[0026] Multiple slotted holes 224 are provided on the upper side of the connecting plate 22. A countersunk hole is provided at the bottom of the base plate 21 corresponding to each slotted hole 224. The base plate 21 and the connecting plate 22 are fixed together by bolt and nut pairs 24 and the corresponding countersunk holes and slotted holes 224. In this embodiment, after the bolt and nut pairs 24 are installed, the top of the bolt is still lower than the upper surface of the snap-fit ​​strip 221, ensuring that the battery 5 can be smoothly installed in the battery mounting bracket 2 by engaging the snap-fit ​​strip 221.

[0027] A mounting hole is provided at one edge of the bottom of the support plate 12, through which a lock head 6 is installed. A first through hole and a second through hole are provided on the base plate 21 and the connecting plate 22 respectively, corresponding to the lock cylinder of the lock head 6. The lock cylinder can pass through the first through hole and the second through hole to achieve locking between the base plate 21, the connecting plate 22 and the support plate 12.

[0028] It also includes a limiting frame 4, which includes two parallel connecting rods 41. An inverted U-shaped limiting plate 42 is fixed upward between the front ends of the two connecting rods 41. The two connecting rods 41 overlap the upper side of the connecting plate 22, and one of the connecting rods 41 has a third through hole 43 corresponding to the lock cylinder, into which the lock cylinder can be inserted. The rear end of the other connecting rod 41 has a limiting block 44 that abuts against the rear end of the connecting plate 22. The distance between the bottom end of the limiting block 44 and the upper surface of the connecting rod 41 is less than the distance between the upper surface of the snap-fit ​​strip 221 and the upper surface of the connecting plate 22. The depth of the lock cylinder extending into the third through hole 43 is greater than the distance between the upper surface of the connecting rod 41 and the lower surface of the battery 5 when the connecting rod 41 is attached to the upper side of the connecting plate 22. This ensures that when the battery 5 is installed, after the lock cylinder locks the connecting rod 41 together with the connecting plate 22, the base plate 21 and the support plate 12, the limiting frame 4 will not be pulled out from the battery mounting bracket 2, thereby ensuring the safety of the battery 5 and playing an anti-theft role. In this embodiment, the lock head 6 is a conventional structure with a lock cylinder having a columnar upper part. No improvements have been made to the lock head 6, therefore, its internal structure is not described in detail here.

[0029] A crossbar 25 is fixedly connected to the rear opening of the upper cover 23, and a handle 26 is fixedly connected to the rear side of the crossbar 25. The crossbar 25 limits the rear end of the battery 5. The handle 26 is set so that it is easy to pick up after the battery mounting bracket 2 is removed. You can hold the bottom front side of the battery mounting bracket 2 with one hand and hold the handle 26 with the other hand to transfer the battery mounting bracket 2 with the battery 5. If the battery 5 is removed from the battery mounting bracket 2, you can hold the handle 26 with one hand to transfer the battery mounting bracket 2.

[0030] Multiple perforated holes 231 are provided on both the left and right sides of the upper cover 23, which achieves the effect of reducing weight and saving materials while ensuring rigid support.

[0031] Multiple strip-shaped protrusions 15 are provided on the upper and lower side walls of the support plate 12 where they contact the base plate 21, which serve to prevent slipping and reduce wear.

[0032] The upper side of the connecting plate 22 is also fixed to a support platform 222 by multiple vertically arranged and spaced connecting strips 223. The support platform 222 supports the battery 5. In this embodiment, the bottom end of the connecting strip 223 is fixed to the upper side of the connecting plate 22, and the top end is fixed to the bottom of the support platform 222. The support platform 222 further improves the support stability of the battery 5 and effectively reduces the stress generated when the snap-fit ​​strip 221 supports the battery 5. At the same time, the connecting strip 223 also acts as a fin to dissipate heat to a certain extent.

[0033] The working process of this embodiment is as follows: During installation, the support frame 1 is placed on the left side of the electric bicycle frame above the rear wheel, and the mounting plate 11 is fixed to the frame. Then, the battery mounting bracket 2 is snapped onto the support plate 12 of the support frame 1 through the engagement of the engagement boss 211 and engagement groove 13, as well as the engagement of the engagement strip 212 and the two sides of the support plate 12. The battery 5 is slidably snapped onto the connecting plate 22 through the engagement of the engagement edge 51 and engagement strip 221. Then, the two connecting rods 41 of the limiting frame 4 are inserted from front to back into the gap between the battery 5 and the connecting plate 22, so that the front side of the limiting block 44 abuts against the rear end of the connecting plate 22. At this time, the limiting plate 42 is located in the middle of the front side of the battery 5. Finally, the locking head 6 is locked by the key of the locking head 6, that is, by rotating the lock cylinder with the key, the lock cylinder moves upward until it passes through the first through hole and the second through hole in sequence and is inserted into the third through hole 43, thus realizing the fixation between the limiting frame 4, the battery mounting bracket 2 and the support frame 1.

[0034] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
