AI Technical Summary

Benefits of technology

This patented technology allows easy connection or disconnection of both the seat pad support system (S) and the fixing frames used with them without leaving any holes that could allow criminals to turn around their chairs while still being able to use this device effectively. Additionally, there're no parts like batteries inside these systems which might get damaged during operation due to collisions caused by external forces. Overall, this innovative design enhances security measures against pickpockets attacks.

Problems solved by technology

This patented technical problem addressed by the current design for electrical bike structures involves making sure they are securely locked when charging or discharged without being able to turn them back on again if needed due to their placement close enough together with other components like the seat pad. Additionally, there may exist gaps where repeated collision occurs causing noisy sounds from the battery's movement inside the electric vehicle body.

Embodiment Construction

[0011] As shown in the figure, the device includes a seat cushion bracket installed on the front top of the battery 1 of the electric bicycle. The seat cushion bracket is composed of a fixed frame 2 and a movable frame 3 that is hinged with the fixed frame and can be turned forward. A seat cushion 4 is installed on the frame, and the bottom of the fixed frame is connected with an intubate 6 that can be inserted into the insertion hole 5 on the vehicle frame. Such as image 3 As shown, a lock body 7 is installed on the movable frame 3, and the lock body has a dead bolt 8 that can be controlled by a key to expand and contract. When dead bolt 8 stretches out in the groove 9, movable frame can't turn over.

[0012] The lower end surface of the intubation tube 6 is an inclined plane, and a wedge nut 10 is arranged below the intubation tube. The top surface of the wedge nut is an inclined plane corresponding to the lower end surface of the intubation tube, and a long screw rod 11 pass

Abstract

The invention relates to an anti-theft device of an electric bicycle battery. The device comprises a seat cushion bracket which is arranged on the front upper side of the electric bicycle battery, wherein the seat cushion bracket consists of a fixing frame and a movable frame which can be hinged with the fixing frame and turned forwards; the movable frame is provided with a seat cushion; the bottom of the fixing frame is connected with a spile which can be inserted into a splicing hole on a vehicle frame; the movable frame is provided with a lock body, and the lock body is provided with a bolt which can be controlled to extend or retract by a key; the fixing frame is provided with a groove which can be matched with the extended bolt; and when the bolt extends into the groove, the movable frame can not be turned over. The anti-theft device has the advantages of convenient use and good anti-theft effect and can alleviate the bump and the vibration between the battery and the vehicle frame.
