[0025] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0026] See also Figures 1 to 4 In the utility model: a bicycle battery box with anti-theft function, comprising an installation box 1, the top of the installation box 1 is open, a battery pack 2 is installed inside the installation box 1, the top of the installation box 1 is detachably connected to a top plate 4 by four bolts 3, an anti-theft cover 5 is arranged on the top of the top plate 4, an anti-theft lock 6 is installed on the left side of the anti-theft cover 5, the lock core of the anti-theft lock 6 is fixedly connected to a driving plate 7, a fixing box 8 is fixedly connected to the top of the top plate 4, a locking plate 9 slidably connected to the fixing box 8 is inserted on the right side of the fixing box 8, a trapezoidal block 10 is fixedly connected to the left side of the locking plate 9, two springs 11 are fixedly connected to the right side of the trapezoidal block 10, the other ends of the two springs 11 are fixedly connected to the fixing box 8, a vertical plate 12 is fixedly connected to the inner side of the anti-theft cover 5, and a lock hole 13 adapted to the locking plate 9 is opened on the vertical plate 12.

[0027] In the utility model, the bolt 3 fixes the top plate 4 to the opening at the top of the installation box 1, thereby locking and installing the battery pack 2. When the battery pack 2 is anti-theft, the user inserts the key into the keyhole of the anti-theft lock 6 and rotates the key. The key drives the lock cylinder to rotate, and the lock cylinder then drives the driving plate 7 to rotate. After the driving plate 7 rotates, it squeezes the trapezoidal block 10. After the trapezoidal block 10 is squeezed, it drives the locking plate 9 to deviate. The locking plate 9 approaches the vertical plate 12 fixedly connected to the inner side of the anti-theft cover 5 until the locking plate 9 is inserted into the lock hole 13 on the vertical plate 12. Then, the locking plate 9 locks the vertical plate 12, thereby realizing the anti-theft. The anti-theft cover 5 has a locking effect. When the key is pulled out, the anti-theft cover 5 will be locked on the top of the installation box 1. The protruding part on the inner side of the anti-theft cover 5 will block all the bolts 3, thereby achieving the anti-theft effect on the top plate 4, thereby effectively preventing the top plate 4 from being disassembled, and improving the anti-theft effect of the battery pack 2. When the battery pack 2 needs to be taken out, the user inserts the key and rotates the key in the opposite direction. At this time, the driving plate 7 will lose the squeeze on the trapezoidal block 10, and the elastic force of the spring 11 will drive the locking plate 9 to be pulled out of the key hole 13. At this time, the anti-theft cover 5 can be removed, and then the bolts 3 can be rotated to remove the top plate 4, and the battery pack 2 can be taken out for maintenance.

[0028] See also Figure 1 and 2 , wherein: the top of the battery pack 2 is electrically connected to a power display module 14 , and the power display module 14 is installed on the top of the anti-theft cover 5 ; the top of the battery pack 2 is electrically connected to a charging module 18 , and the charging module 18 is installed on the right side of the anti-theft cover 5 .

[0029] In the present invention, the power display module 14 can monitor and display the power usage of the battery pack 2, thereby facilitating the user to charge the battery pack 2 in a timely manner through the charging module 18.

[0030] See also Figures 1 to 3, wherein: a window 15 is provided on the right side of the anti-theft cover 5 , and a handle 16 is fixedly connected to the inner side of the window 15 .

[0031] In the present invention, the handle 16 provided on the window 15 can facilitate the user to carry the installation box 1 , thereby improving the portability of the battery pack 2 .

[0032] See also Figure 3 , wherein: four positioning rods 17 are fixedly connected to the top of the top plate 4, and the top ends of the four positioning rods 17 are inserted into the anti-theft cover 5 and slidably connected thereto.

[0033] In the utility model, the positioning rod 17 can not only position the anti-theft cover 5, but also limit the anti-theft cover 5, thereby improving the practicability of the device.

[0034] See also Figure 4 , wherein: a pressure sensor 19 is embedded on the outer side of the driving plate 7 , and a wear-resistant block 20 is fixedly connected to the outer side of the pressure sensor 19 .

[0035] In the utility model, when the anti-theft cover 5 is locked, squeezing will occur between the driving plate 7 and the trapezoidal block 10, and the pressure sensor 19 will detect a value. When the anti-theft cover 5 is unlocked or violently opened, the driving plate 7 will lose the squeezing of the trapezoidal block 10, and the pressure value detected by the pressure sensor 19 will disappear. By observing the change in the pressure value, the user can know whether the anti-theft cover 5 is locked or whether the battery pack 2 is likely to be stolen, and then the battery pack 2 can be checked at the first time to reduce the possibility of the battery pack 2 being stolen, thereby improving the anti-theft effect of the device.

[0036] The above are only preferred specific implementations of the utility model; however, the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solution and improved ideas of the utility model within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model.
