[0021] In order to better understand the control system and control method thereof of the present invention, a gluing device for an end cover of a harmonic reducer of the present invention is further described in detail below in conjunction with the accompanying drawings.

[0022] like Figures 1 to 10 As shown, the present invention discloses a battery pack side locking mechanism, comprising: A battery pack guiding device 2 and a battery pack mounting slot, wherein the battery pack guiding device 2 is fixedly arranged at the upper end of the battery pack mounting slot. The battery pack mounting slot is used to place the battery pack 1, and the battery pack guiding device 2 includes at least two mounting slots 21. The number of battery packs 1 that can be placed in the battery pack mounting slot 2 is equal to the number of mounting slots 21. When the battery pack 1 is placed in the battery pack mounting slot, the battery pack guiding device 2 guides the battery pack 1. A limiting hole 211 is provided on the inner side wall of the mounting slot 21. The number of the limiting holes 211 is not fixed, and can be 1, 2, 3 or more.

[0023] In this embodiment, as a preferred solution, the number of the installation slots 21 is 3. However, the number of the installation slots 21 is not limited to 3, and may also be 2, 4, 5, etc.

[0024] The battery pack 1 includes a battery pack body, an electrical connector plug, a lower end cover, and an upper end cover 11. The lower end cover is fixedly arranged at the lower end of the battery pack body, the upper end cover 11 is fixedly arranged at the upper end of the battery pack body, and the electrical connector plug is embedded in the battery pack body. A buckle 111 adapted to a limiting hole 1211 is arranged on the outer wall of the upper end cover 11. When the battery pack 1 is placed in the battery pack installation slot, the buckle 111 is stuck in the limiting hole 1211. When the battery pack 1 is lifted from the battery pack installation slot, the buckle 111 is disengaged from the limiting hole 1211. The battery pack side locking mechanism locks the upper end cover 11 of the battery pack 1 with the battery pack guide device through the cooperation of the limiting hole 1211 and the buckle 111 to prevent the battery pack 1 from shaking in the battery pack installation slot.

[0025] The battery pack side locking mechanism further includes a battery pack handle 3. The battery pack handle 3 is mounted on the upper end of the upper end cover 11, and the battery pack handle 3 can rotate around the upper end cover 11 between a vertical plane and a horizontal plane.

When the battery pack handle 3 is rotated downward to a horizontal state, the second buckle 112 is clamped in the second limiting hole 311, and the battery pack handle 3 is fastened to the upper end of the battery pack 1, thereby playing a role in fastening the battery pack 1. At the same time, the battery pack hanging plate 5 drives the electric connector body 4 to move forward to the front end along the electric connector guide part 6, and the electric connector plug and the electric connector body 4 are in a tightly plugged state.

[0027] In this embodiment, as a preferred solution, the buckle 111 and the buckle 2 112 are an integrated part, and the integrated part is a plastic part. The plastic part is elastic and is made of elastic material.

[0028] Specifically, the buckle 112 includes a cantilever 1121 and a boss 1122 that cooperates with the limiting hole 2, the boss 1122 is located in the middle position of the cantilever 1121, and the upper end of the cantilever 1121 is fixed to the inner side of the upper end cover 11. The upper end surface of the cantilever 1121 is inclined, and the upper end surface is inclined upward from front to back. The inclined upper end surface can ensure that the buckle 112 is more susceptible to horizontal inward pressure during the downward rotation of the battery pack handle 3 from a vertical state, and the buckle 112 is easily compressed. When the battery pack handle 3 is in a horizontal state, the buckle 112 is more likely to enter the limiting hole 311 and firmly cooperate with the limiting hole 311, which is convenient and labor-saving.

[0029] The boss 1122 includes an upper end face 2, a lower end face 2, a front end face 2 and two side end faces, the upper end face 2 and the lower end face 2 are both inclined, the upper end face 2 is inclined upward from front to back, and the lower end face 2 is inclined downward from front to back. The shape of the second limiting hole 311 matches the shape of the second buckle 112, and the shape of the second limiting hole 311 is a quadrilateral groove.

[0030] The buckle 111 is fixed to the lower end of the cantilever 1121 , and a through hole is provided on the upper end cover 11 , and the buckle 111 passes through the through hole and extends to the inner side of the upper end cover 11 .
