DETAILED DESCRIPTION

[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] See also Figures 1 to 7 In an embodiment of the utility model, a battery anti-theft device for an electric vehicle comprises a battery box 1, a box cover 2 and a plurality of batteries 8 arranged in the battery box 1, a locking plate 3 is provided between the box cover 2 and the battery 8, a locking assembly 4 is provided in the locking plate 3, the locking plate 3 is plugged and connected to the battery box 1 through the locking assembly 4, a hidden plate 5 is provided above the locking plate 3, the hidden plate 5 can hide the special-shaped lock hole 42, a slide rail 6 is fixedly connected to the inner wall at the bottom of the battery box 1, a slide groove 7 is provided on the bottom wall of the battery 8, the shape of the slide rail 6 and the slide groove 7 is a matching T-shape, the slide rail 6 and the slide groove 7 are plugged and connected, the slide rail 6 is provided with a vacant section 61 at a position opposite to one of the plurality of batteries 8, the battery 8 can only be installed and removed from the vacant section 61, and a clamping device 9 is fixedly connected to the inner wall on the right side of the battery box 1.

[0027] The battery box 1 and the box cover 2 are fixedly connected by a plurality of bolts. Two limit blocks 34 are provided below the locking plate 3, and the two limit blocks 34 are fixedly connected to the two side walls of the battery box 1 respectively.

[0028] like Figure 4 As shown, two second through holes 32 are respectively provided on the two side walls of the locking plate 3, and the two second through holes 32 are staggered up and down. The battery box 1 is respectively provided with locking grooves 11 at positions opposite to the two second through holes 32, and two guide plates 33 are fixedly connected to the locking plate 3.

[0029] The locking assembly 4 includes a gear 41, a special-shaped lock hole 42, a tooth plate 43, and a locking column 44. The gear 41 is rotatably connected to the locking plate 3. The gear 41 is provided with a special-shaped lock hole 42. The gear 41 is meshed with tooth plates 43 on both sides. The tooth plates 43 slide between the guide plate 33 and the side wall of the locking plate 3. The ends of the two tooth plates 43 away from each other are fixedly connected with a locking column 44. The locking column 44 is slidably connected to the second through hole 32, and the locking column 44 is plug-connected to the locking groove 11. When the locking assembly 4 needs to be unlocked, a specific tool needs to be inserted into the special-shaped lock hole 42, and the tool is rotated counterclockwise to drive the gear 41 to rotate. The gear 41 drives the tooth plates 43 on both sides to move inward, thereby driving the locking column 44 to move out of the locking groove 11 to release the lock.

[0030] like Figure 3 As shown, a first through hole 31 is provided on the top wall of the locking plate 3. The first through hole 31 is located opposite to the special-shaped locking hole 42 and is used for inserting a tool matched with the special-shaped locking hole 42 to unlock the lock.

[0031] like Figure 2 As shown, the hidden plate 5 is fixedly connected to the locking plate 3 by bolts.

[0032] like Figure 1 As shown, the clamping device 9 includes an internal threaded barrel 91, an external threaded rod 92 and a clamping plate 93. The internal threaded barrel 91 is fixedly connected to the right inner wall of the battery box 1. The internal threaded barrel 91 is internally threaded with the external threaded rod 92. The other end of the external threaded rod 92 is rotatably connected to the clamping plate 93. Both sides of the clamping plate 93 are slidably connected to the side wall of the battery box 1. Figure 7 As shown, an avoidance portion 94 is provided below the clamping plate 93 , and the avoidance portion 94 is arranged at a position opposite to the slide rail 6 to avoid interference between the clamping plate 93 and the slide rail 6 when the clamping plate 93 moves.

[0033] like Figure 5 As shown, the slide rail 6 is provided with a vacant section 61 at a position opposite to one of the multiple batteries 8. In the embodiment of the utility model, the vacant section 61 is provided at a position opposite to the second battery 8 on the left side.

[0034] When installing multiple batteries 8, it is first necessary to place the batteries 8 according to a specific order and operation. First, insert the first battery 8 from the empty section 61 into the battery box 1 to contact the bottom, then push the first battery 8 to the far left, plug the slide rail 6 and the slide groove 7 into connection, and fix it in the longitudinal direction. Then, insert the second battery 8 from the empty section 61 into the battery box 1, push it to the right, and plug it into the slide rail 6 on the right. In this way, install the subsequent batteries 8, and the last battery 8 is inserted into the battery box 1 from the empty section 61 and placed in the empty section 61; then, rotate the external threaded rod 92 by a tool to move the external threaded rod 92 to the left, drive the clamping plate 93 to move to the left to clamp the battery 8, thereby fixing the battery 8 in the horizontal direction. At the same time, the setting of the clamping device 9 can adapt to different numbers of batteries 8 in the battery box 1, and can be adjusted according to the needs of the electric vehicle.

[0035] The working principle of the utility model is as follows: the utility model sets multiple protections for the electric vehicle battery, which minimizes the possibility of the electric vehicle battery being stolen. When someone wants to open the battery box 1 to steal the internal battery 8, he first needs to open the box cover 2 by screwing the bolts. When the box cover 2 is opened, the thief sees the following situation: Figure 2 As shown, the battery 8 is not seen. If you want to continue the theft, you need to screw the bolt again to open the hidden plate 5. After opening the hidden plate 5, you will see the following situation: Figure 3 As shown, the battery 8 is still not seen. If one wants to continue opening the lock, a special tool compatible with the special-shaped lock hole 42 is needed to open the locking plate 3, which increases the difficulty of theft, thereby reducing the occurrence of some theft behaviors; if the thief opens the locking plate 3 and sees the battery 8, if he wants to take out the battery 8, he first needs to use a tool to release the clamping device 9 from the battery 8. If he does not carry a tool, he cannot take out the battery 8. After releasing the clamping device 9, if he wants to take out multiple batteries 8, he also needs to follow a specific order and operation to take out the batteries 8, that is, he needs to take out the second battery 8 on the left first, and then the batteries on the left and right sides slide to the empty section 61 in sequence, and after releasing the connection between the slide rail 6 and the slide slot 7, they are taken out from the empty section 61. If this specific order is not clear, the battery 8 cannot be taken out. Through the multiple protections in the structure of the utility model, the battery 8 can be effectively prevented from being stolen.

[0036] Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art may still modify the technical solutions described in the aforementioned embodiments, or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention shall be included in the protection scope of the present invention.
