Description

Technical Field

[0001] The utility model relates to the technical field of electric bicycles, and particularly relates to an electric bicycle lithium battery with an anti-theft function. Background Art

[0002] An electric bicycle refers to a mechatronic personal transportation vehicle that uses a storage battery as an auxiliary energy source and is based on an ordinary bicycle, equipped with a motor, a controller, a storage battery, operating components such as a handlebar and a brake lever, and a display instrument system. It usually uses a lithium battery for power supply and drives the wheels through the motor to assist riding, making the riding easier and more labor-saving. Since the lithium battery needs to be frequently disassembled and replaced, it is mainly set in a detachable structure with the electric bicycle.

[0003] At present, most of the lithium batteries of electric bicycles are placed in the battery compartment under the pedal and pressed by a metal frame, and only bolts are used to lock between the pedal and the body frame. There is also a lack of additional anti-theft connection between the lithium battery with an integrated box structure and the battery compartment, making it easy for the lithium battery of the electric bicycle to be stolen when parked outdoors, and thus causing property losses to the owners of electric bicycles. Therefore, we propose an electric bicycle lithium battery with an anti-theft function. Content of the Utility Model

[0004] The main purpose of the utility model is to provide an electric bicycle lithium battery with an anti-theft function. An anti-theft mechanism is arranged at the lithium battery body. When the lithium battery body is stolen and disassembled at the battery compartment of the electric bicycle, the anti-theft mechanism installs a bottom connection plate at the bottom of the lithium battery body and cooperates with bolts with a special limiting structure at the bottom of the battery compartment. When a thief disassembles the pedal above the battery compartment and lifts the lithium battery body, the bottom connection plate below the lithium battery body is locked in the battery compartment and cannot be lifted out, realizing the anti-theft and anti-disassembly of the lithium battery body at the battery compartment below the electric bicycle. And when the bolts at the bottom of the battery compartment are found and disassembled by the thief, the thief does not know that the bolts are limited in the bottom connection plate and cannot rotate. When the thief finds that the bolts cannot rotate, they will also give up stealing the lithium battery body, which can effectively solve the problems in the background art.

A T-shaped groove 11 is centrally opened on the bolt body of the bolt 10, and the upper rod head and the vertical rod body of the T-shaped rod 9 are clamped into the T-shaped groove 11. A rubber sealing plate 12 covering the bottom slot hole of the T-shaped groove 11 is adhered to the head surface of the bolt 10.

[0027] Among them, heat dissipation grooves 13 penetrating the plate body of the bottom connecting plate 3 are opened on the surface of the bottom connecting plate 3, and heat dissipation grooves 13 penetrating the bottom connecting plate 3 are opened on the groove wall of the U-shaped groove 4;

[0028] By adopting the above technical solution, heat dissipation grooves 13 are provided at the bottom connecting plate 3 and the groove wall of the U-shaped groove 4, so that the bottom of the lithium battery body 1 can dissipate heat downward.

[0029] Among them, the size of the cavity of the battery compartment 14 is larger than the size of the block body after the lithium battery body 1 is fixed with the bottom connecting plate 3;

[0030] By adopting the above technical solution, the lithium battery body 1 pressing the bottom connecting plate 3 can be smoothly clamped into the battery compartment 14, and then some buffer rubber plates or foam plates can be filled in the gap between the battery compartment 14 and the lithium battery body 1.

[0031] Among them, the height of the side panel body of the rod head of the T-shaped rod 9 is less than the height of the ring body of the guiding ring 7, and the height of the ring body of the guiding ring 7 is less than the depth of the cavity of the U-shaped groove 4;

[0032] By adopting the above technical solution, the side panel body of the rod head of the T-shaped rod 9 can be pushed upward from the guiding ring 7 into the U-shaped groove 4, so that the bolt 10 can be normally screwed out downward from the vertical rotation hole 5 below the guiding ring 7.

[0033] Among them, the side panel body of the rod head of the T-shaped rod 9 is clamped into the horizontal cavity of the T-shaped groove 11 and the cavity of the T-shaped limiting groove 8;

[0034] By adopting the above technical solution, the side panel body of the rod head of the T-shaped rod 9 can be clamped into the horizontal cavity of the T-shaped groove 11 and the cavity of the T-shaped limiting groove 8, so that the bolt 10 is restricted from rotating.

[0035] Among them, vertical connection holes are provided in the middle of the ring pressing plate 6 and the guide ring 7, and a bolt 10 that rotates upward at the vertical rotation hole 5 passes through the vertical connection holes.

[0036] By adopting the above technical solution, the bolt 10 can penetrate into the vertical connection holes of the ring pressing plate 6 and the guide ring 7.

[0037] It should be noted that the present utility model is an electric bicycle lithium battery with an anti-theft function. An anti-theft mechanism 2's bottom connection plate 3 is arranged at the lithium battery body 1. After the ring pressing plate 6 is welded in the U-shaped groove 4 of the bottom connection plate 3, the guide ring 7 is welded on the surface of the ring pressing plate 6. The T-shaped rod 9 can be inserted downward into the T-shaped limiting groove 8 of the guide ring 7, so that the vertical rod body of the T-shaped rod 9 passes downward from the vertical rotation hole 5. Then, the bottom connection plate 3 can be welded to the metal shell at the bottom of the lithium battery body 1. At this time, the lithium battery body 1 can be placed in the battery compartment 14 of the electric bicycle with the bottom connection plate 3, so that the vertical rod body of the T-shaped rod 9 passes downward through the threaded bottom hole 15 of the battery compartment 14. Then, the bolt 10 is screwed into the threaded bottom hole 15 and screwed into the vertical rotation hole 5. When the bolt 10 is screwed into the guide ring 7, a metal rod is inserted into the T-shaped groove 11 of the bolt 10, so that the rod head of the T-shaped rod 9 drives the side panel body to move upward away from the T-shaped limiting groove 8. Then, the bolt body of the bolt 10 can enter the vertical connection holes of the ring pressing plate 6 and the guide ring 7. At this time, the metal rod is removed, and the rod head and side panel body of the T-shaped rod 9 can fall downward into the T-shaped limiting groove 8 and the T-shaped groove 11 of the bolt 10 for positioning. At this time, the bolt 10 is restricted by the T-shaped rod 9 and cannot rotate. The glue-sealing plate 12 can be bonded to the bottom surface of the head of the bolt 10 to block the vertical groove hole of the T-shaped groove 11. The glue-sealing plate 12 can be coated with color paint so that the color of the glue-sealing plate 12 is similar to the color of the bolt 10. When replacing the lithium battery body 1, only need to use a blade to cut away the glue-sealing plate 12 from the bottom surface of the head of the bolt 10, so that the vertical groove hole of the T-shaped groove 11 on the head of the bolt 10 is exposed. Then, use a metal rod to push the T-shaped rod 9 upward, so that the head and side panel body of the T-shaped rod 9 leave the T-shaped limiting groove 8 and the T-shaped groove 11. At this time, the bolt 10 can be unscrewed downward from the bottom connection plate 3, and then the lithium battery body 1 with the fixed bottom connection plate 3 can be taken out from the battery compartment 14 for replacement. When the lithium battery body 1 is stolen and disassembled at the battery compartment 14 of the electric bicycle, when the thief disassembles the pedal above the battery compartment 14 and lifts the lithium battery body 1, the bottom connection plate 3 below the lithium battery body 1 is locked in the battery compartment 14 and cannot be taken out. Even when the bolt 10 at the bottom of the battery compartment 14 is discovered and disassembled by the thief, the thief does not understand that the bolt 10 is limited in the bottom connection plate 3 and cannot rotate. Finding that the bolt 10 cannot rotate, the thief will give up stealing the lithium battery body 1.
