[0041] The present application provides a battery anti-theft mechanism for locking a battery in a battery compartment to prevent the battery from being stolen. The battery anti-theft mechanism includes a lower support 1, a positioning seat 2, a locking member 3, a cam 4 and a driver 5. Figure 1 and Figure 2 As shown. A locking groove 11 is provided on the inner side of the lower support 1. A sliding cavity 22 is provided inside the positioning seat 2, and the sliding cavity 22 has a lateral opening 21. The locking member 3 is slidably arranged in the sliding cavity 22, and the locking member 3 can be controlled to move in the sliding cavity 22 and a part of the locking member 3 can extend from the lateral opening 21. The cam 4 is arranged in the sliding cavity 22 and is located on the side of the locking member 3 away from the lateral opening 21. The outer side of the cam 4 is provided with a protrusion 41, as shown in FIG. Figure 2 and Figure 3The driver 5 is connected to the positioning seat 2, and the driver 5 is drivingly connected to the cam 4. The driver 5 can drive the cam 4 to rotate so that the protrusion 41 pushes the locking member 3 to move in the sliding cavity 22 and partially extend out of the lateral opening 21.

[0042] When the battery anti-theft mechanism is applied to the field of battery anti-theft, the lower support 1 is fixedly arranged below the battery 7, and the positioning seat 2 can be fixed in the battery compartment. When the battery 7 is placed in the battery compartment, the lower support 1 is located on the positioning seat 2, and at this time, the lateral opening 21 of the slide cavity 22 is arranged opposite to the locking groove 11 of the lower support 1. Then, the control driver 5 is operated, and the cam 4 is driven to rotate so that the protrusion 41 pushes the locking member 3 to move in the slide cavity 22 and partially extends from the lateral opening 21 and then inserts into the locking groove 11, thereby locking the battery 7 in the battery compartment. Since the lower support 1 and the positioning seat 2 are located below the battery 7, the locking structure can be hidden, thereby improving the anti-theft performance.

[0043] like Figure 2 As shown, the size of the lateral opening 21 is smaller than the size of the sliding cavity 22, and the locking member 3 includes a connected positioning block 31 and a sliding seat 32, and the size of the positioning block 31 is smaller than the size of the sliding seat 32. Among them, the sliding seat 32 is located on the side close to the cam 4, and the positioning block 31 is located on the side close to the lateral opening 21. The size of the sliding seat 32 is adapted to the size of the sliding cavity 22, and the sliding seat 32 is slidably connected to the inner wall of the sliding cavity 22, which can improve the stability of movement. The size of the positioning block 31 is adapted to the size of the lateral opening 21, and the positioning block 31 is slidably connected to the inner wall of the lateral opening 21, which can further improve the stability of movement and improve the reliability of locking. When the driver 5 drives the cam 4 to rotate, the protrusion 41 pushes the sliding seat 32 to move in the sliding cavity 22, thereby pushing the positioning block 31 to move inside and outside the lateral opening 21. When the locking member 3 is locked with the locking groove 11, the slide seat 32 is limited in the slide cavity 22 by the inner walls on both sides of the lateral opening 21, and part of the positioning block 31 extends from the lateral opening 21 and is inserted into the locking groove 11, thereby preventing the locking member 3 from escaping from the slide cavity 22 and improving the stability of the locking.

[0044] See also Figure 2 As shown, the battery anti-theft mechanism also includes an elastic reset member 6. The elastic reset member 6 is arranged in the slide cavity 22 and installed between the slide seat 32 and the inner wall of the slide cavity 22. In the process of the locking member 3 moving outward and inserting into the locking groove 11, the distance between the slide seat 32 and the inner wall of the slide cavity 22 is gradually shortened to compress the elastic reset member 6. When the driver 5 drives the cam 4 to rotate in the reverse direction, the protrusion 41 separates from the slide seat 32, and the elastic reset member 6 pushes the slide seat 32 to make the locking member 3 move back to the slide cavity 22 as a whole to disengage from the locking groove 11, thereby completing the removal of the battery.

[0045] See also Figure 2As shown, the inner wall of the slide cavity 22 is provided with a guide groove 23, and the slide seat 32 is provided with a limit slider 33. The width and height of the limit slider 33 are consistent with the width and height of the guide groove 23, and the limit slider 33 is slidably connected in the guide groove 23, and is used to slide and guide the positioning block 31 and the slide seat 32 when they are moved and adjusted, which is conducive to improving the stability of the sliding adjustment positioning of the positioning block 31 and the slide seat 32, and is convenient for improving the stability of the insertion and positioning of the positioning block 31 and the locking groove 11. Preferably, the guide grooves 23 can be provided on both sides of the inner wall of the slide cavity 22, and the limit sliders 33 are provided on both sides of the slide seat 32. The two sides of the slide seat 32 are slidably connected with the guide groove 23 through the limit sliders 33, which further improves the stability of the sliding adjustment positioning, and the stability of the insertion and positioning of the positioning block 31 and the locking groove 11.

[0046] See also Figure 1 and Figure 2 As shown, the lower support 1 is provided with a receiving cavity 12, the receiving cavity 12 has a bottom opening, and the locking groove 11 is arranged on the side wall of the receiving cavity 12. The positioning seat 2 includes a base 24 and a boss 25 integrally formed above the base 24. The sliding cavity 22 is arranged in the middle of the boss 25. Among them, the transverse dimension of the boss 25 is smaller than the transverse dimension of the receiving cavity 12, the height of the boss 25 is less than or equal to the height of the receiving cavity 12, and the transverse dimension of the base 24 is larger than the transverse dimension of the receiving cavity 12. When the battery 7 is placed in the battery compartment, the boss 25 extends into the receiving cavity 12, and the lower support 1 is located above the base 24. At this time, the lateral opening 21 is arranged opposite to the locking groove 11. Therefore, the driver 5 can drive the locking member 3 to move out of the sliding cavity 22 and insert into the locking groove 11 to achieve locking of the battery 7.

[0047] See also Figure 1 and Figure 2 As shown, the base 24 includes a groove 241 with a bottom opening. The groove 241 is arranged below the sliding cavity 22 . The groove 241 is connected to the sliding cavity 22 through a connecting through hole 26 .

[0048] The driver 5 can be fixed in the groove 241 by bolts or the like, and the driving rod of the driver 5 extends into the sliding cavity 22 through the connecting through hole 26 and is connected to the cam 4. Thus, the driver 5 can drive the cam 4 to rotate. The driver 5 can be a structure such as a motor or a rotary cylinder that can drive the cam 4 to rotate. When the positioning seat 2 is installed in the battery compartment, the driver 5 can be hidden to prevent the driver 5 from being stolen or damaged.

[0049] In a preferred implementation, the lower support 1 is provided with two symmetrically arranged locking grooves 11, the sliding cavity 22 has two symmetrically arranged lateral openings 21, two symmetrically arranged locking members 3 are slidably arranged in the sliding cavity 22, and two protrusions 41 are symmetrically arranged on the outer side of the cam 4, and the cam 4 is arranged between the two locking members 3. Figure 1 and Figure 2 The structures of the lower support 1, the positioning seat 2, the locking member 3 and the sliding cavity 22 are the same as those in the above-mentioned manner, and will not be described in detail.

[0050] When the lower support 1 is placed on the positioning seat 2, the two lateral openings 21 are connected to the two locking grooves 11 respectively. The driver 5 drives the cam 4 to rotate forward 90 degrees so that the two protrusions 41 push the two locking members 3 to move respectively, and the two locking members 3 extend from the two lateral openings 21 and insert into the two locking grooves 11 respectively, thereby locking the battery 7. The locking operation is convenient and quick, and the locking stability can be further improved. When the driver 5 drives the cam 4 to rotate in the opposite direction by 90 degrees, the two locking members 3 are separated from the locking grooves 11 respectively under the action of the two elastic reset members 6, and the battery is disassembled.

[0051] In other implementations, a plurality of protrusions 41 may be provided on the cam 4 at equal angles along the circumference, a plurality of locking grooves 11 may be provided on the inner side wall of the lower support 1 at equal angles along the circumference, a plurality of lateral openings 21 may be provided on the sliding cavity 22 at equal angles along the circumference, and a plurality of locking members 3 may be provided in the sliding cavity 22. In other words, the number of protrusions 41, locking grooves 11, lateral openings 21, and locking members 3 are the same, and their positions correspond one to one. The driver 5 drives the cam 4 to rotate so that the plurality of protrusions 41 respectively push the plurality of locking members 3 to move, and the plurality of locking members 3 respectively extend from the plurality of lateral openings 21 and are inserted into the plurality of locking grooves 11, as shown in FIG. Figure 5 shown.

The positioning seat 2 can be fixed in the battery compartment by fasteners such as bolts passing through the threaded hole 27. The setting position of the threaded hole 27 does not affect the connection with the lower support 1. Preferably, the threaded hole 27 can be a countersunk hole, which is convenient for hiding the head of the bolt in the countersunk hole. After the positioning seat 2 is fixed in the battery compartment, one side of the boss 25 on the positioning seat 2 faces the outside of the battery compartment, which is convenient for the battery 7 to be placed in the battery compartment, so that the battery 7 is connected to the positioning seat 2 through the lower support 1, thereby being fixed in the battery compartment. The battery compartment can be on an electric vehicle, or it can be a battery compartment of a battery exchange cabinet.

[0054] The battery anti-theft mechanism can also be applied to other anti-theft items. For example, a safe. The lower support 1 can be fixed under the safe, and the positioning seat 2 can be fixed in a room or other place where the safe is placed. Thus, by locking the lower support 1 and the positioning seat 2, the safe can be fixed in a designated position.
