[0023] The following further elaborates and explains the present utility model in conjunction with specific embodiments and the accompanying drawings of the specification:

[0024] Please refer to Figures 1 to 2 The present utility model provides a battery installation structure, which includes a battery box 1, an electromagnetic lock 3, a mechanical lock 4 and a base 2.

[0025] Please refer to Figure 2 and Figure 6 As shown in and, one end of the battery box 1 is provided with an assembly part 11, and the other end is provided with a connection part 12. The assembly part 11 is provided with a first card slot 111, a buckle part 112, a limit post 113 and a handle groove. The buckle part 112 is arranged in the first card slot 111. One end of the buckle part 112 is hinged to the side wall of the first card slot ********** between the other end of the buckle part 112 and the bottom of the first card slot 111 is provided with a third elastic member. The third elastic member makes the other end of the buckle part 111 away from the assembly part. The buckle part 112 is provided with a step 1121. Preferably, in order to prevent the third elastic member from moving laterally, the bottom of the first card slot 111 is provided with a receiving hole for placing one end of the third elastic member, which is not shown in the drawings. The handle groove is arranged on the edge of the assembly part 11, and a handle 114 is arranged in the handle groove. The handle 114 is hinged to the side surface of the assembly part 11 and can be accommodated in the handle groove. The handle 114 is convenient for taking out the battery box 1.

[0026] Please refer to Figure 2 and Figure 5, one end of the base 2 is provided with a docking portion 21 that cooperates with the assembly portion 11, and the other end of the base 2 is provided with a support portion 22. The support portion 22 is connected to the connection portion 12 of the battery box 1 by snap connection or abutting connection or other connection methods. When the electromagnetic lock 3 and the mechanical lock 4 are not opened, the battery box 1 is not easily removed. The docking portion 21 is provided with a chute 211, and a second elastic member 212 for limiting the limiting post 113 is arranged in the chute 211. When the assembly portion 11 of the battery box 1 is engaged with the docking portion 21 of the base 2, the second elastic member 212 is used to abut against the limiting post 113 to improve the installation effect of the battery box 1 and the base 2.

[0027] The electromagnetic lock 3 and the mechanical lock 4 are arranged on the docking portion 21. In this embodiment, a hollow hole 213 is provided in the middle of the docking portion 21 for installing the electromagnetic lock 3, and the mechanical lock 4 is arranged on the side of the docking portion 21.

[0028] Please refer to Figure 3 and Figure 4, the electromagnetic lock 3 includes a first locking tongue 31, a dial 32, a first elastic member 33, a baffle 34, a lock body and a silicon steel sheet (not shown in the figure). The first locking tongue 31 and the dial 32 are driven by energizing or de-energizing the silicon steel sheet. Since the electromagnetic lock 3 is a mature technical solution, the connection structure between the silicon steel sheet and the lock body will not be elaborated here. The present utility model designs the connection structure of the first locking tongue 31, the dial 32, the first elastic member 33 and the baffle 34 of the electromagnetic lock 3 to make it have a linkage effect with the mechanical lock 4. Specifically, the first locking tongue 31 is provided with a tongue portion 311 and a shaft portion 312. The tongue portion 311 is Y-shaped and is used to correspond to the first card slot 111. When the tongue portion 311 extends into the first card slot 111, the tongue portion 311 straddles the step 1121 of the buckle member 112. The first card slot 111 and the step 1121 of the buckle member 112 are used to abut against the tongue portion of the first locking tongue 31, so as to prevent the battery box 1 from being taken out when the electromagnetic lock 3 is not unlocked. The dial 32 is sleeved on the shaft portion 312 and fixedly connected to the shaft portion 312. It can be fixedly connected by a clamping method, or by a connecting member such as a screw, or by welding. In other embodiments, it can also be fixedly connected by an integral molding method to make the first locking tongue 31 and the dial 32 move synchronously. A groove 321 is provided on the side of the dial 32. The baffle 34 is fixed on the docking portion 21 of the base 2. In this embodiment, the baffle 34 is provided with a hole for the tongue portion 311 of the first locking tongue 31 to pass through. The tongue portion 311 of the first locking tongue 31 and the dial 32 are respectively located on both sides of the baffle 34. The baffle 34 is used to limit the dial 32. In this embodiment, the first elastic member 33 is sleeved on the shaft portion 312 of the first locking tongue 31. One end of the first elastic member 33 abuts against the dial 32, and the other end abuts against the inside of the lock body and is in a compressed state inside the lock body. The first elastic member 33 causes the tongue portion 311 of the first locking tongue 31 to protrude outward. When the electromagnetic lock 3 is energized, the silicon steel sheet drives the dial 32 and the first locking tongue 31 to move, so that the first locking tongue 31 retracts against the elastic force of the first elastic member 33, and the electromagnetic lock 3 is in an unlocked state. This structure is locked by the elastic force of the first elastic member 33 when not energized, and has a good power-saving effect.

[0029] When installing the battery box 1, the connecting portion 12 of the battery box 1 and the supporting portion 22 of the base 2 are first connected by clamping. Push the other end of the battery box 1. Since the elastic member 33 has elasticity and can retract after being pressed, the assembly portion 11 of the battery box 1 can be pressed into the base 2. The tongue portion 311 of the first locking tongue 31 presses the buckle member 112, and the buckle member 112 presses down against the elastic force of the third elastic member. After the first locking tongue 31 straddles the buckle member 112, the buckle member 112 returns to its original position under the elastic force of the third elastic member, and the first locking tongue 31 is clamped by the buckle member 112. The installation is convenient, the clamping effect is good, and the clamping installation can also be sensed. In other embodiments, one end of the first elastic member 33 can also abut against the tongue portion 311 of the first locking tongue 311.

[0030] The mechanical lock 4 is provided with a second lock tongue 41, which extends into the groove 321 on the side of the paddle 32. In this embodiment, the second lock tongue 41 is an eccentric output structure of the mechanical lock 4, that is, when the mechanical lock 4 is opened, the second lock tongue 41 rotates. By utilizing the principle of its eccentric rotation, after rotating to a certain angle, it pushes the paddle 32 to overcome the elastic force of the first elastic member 33, driving the first lock tongue 31 to retract, thereby opening the first lock tongue 31 of the electromagnetic lock 3.

[0031] As a preferred embodiment, a gap is formed between the second lock tongue 41 of the mechanical lock 4 and the paddle 32. When the electromagnetic lock 3 drives the first lock tongue 31 to open, the second lock tongue 41 does not interfere with the movement of the first lock tongue 31 and the paddle 32. When the mechanical lock 4 is opened, the second lock tongue 41 of the mechanical lock 4 rotates to drive the first lock tongue 31 and the paddle 32 to overcome the elastic force of the first elastic member 33, causing the first lock tongue 31 to disengage from the first slot 111, thereby opening the electromagnetic lock 3. In this embodiment, the electromagnetic lock 3 and the mechanical lock 4 respectively control the first lock tongue 31 through the paddle 32, so that both the electromagnetic lock 3 and the mechanical lock 4 can independently unlock the battery.

[0032] It should be noted that the battery mounting structure proposed in this embodiment can be applied to an electric bicycle, which is provided with a rack for mounting the battery mounting structure.

[0033] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit the scope of protection of the utility model. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in this field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the essence and scope of the technical solution of the utility model.
