Description

Technical Field

[0001] This utility model relates to the field of electric-assisted bicycle technology, specifically to a cable interface for electric-assisted bicycles. Background Technology

[0002] Electric-assisted bicycles are a new type of transportation that uses batteries as an auxiliary power source, is equipped with a motor, and has a power assistance system, enabling both human-powered riding and motor-assisted propulsion.

[0003] The plugs of existing electric bicycles use a common plug-in installation method when they are connected to the power supply interface. There is no external positioning structure between the plug and the interface. As a result, the plug often becomes loose or falls off the interface when it is subjected to external pulling force, causing the connection to be interrupted.

[0004] Therefore, in view of the above-mentioned problems, this technical solution proposes a cable interface for electric-assisted bicycles. Utility Model Content

[0005] The purpose of this invention is to provide a cable interface for electric-assisted bicycles to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a cable interface for an electric-assisted bicycle, including a power source and a connecting wire; a connecting interface is provided at one end of the power source, and a stepped plug is connected to the end of the connecting wire. The plug and the connecting interface are connected by a plug-in connection. A set of positioning members is oscillatingly provided on one side of the top of the connecting interface. The positioning members are used to axially position the plug inserted into the connecting interface, that is, to prevent the plug from loosening or detaching from the connecting interface when the connecting wire is subjected to tension.

[0007] The positioning component includes a positioning component swing groove on the top side wall of the connection interface. A set of swing shafts is rotatably connected inside the positioning component swing groove. A swing block is fixedly installed in the middle of the swing shaft. A rectangular telescopic cylinder plate is installed outward from the swing block. A telescopic plate is telescopically installed inside the telescopic cylinder plate away from the swing block. A vertically installed limit block is installed at the end of the telescopic plate. Adjusting the position of the telescopic plate in the telescopic cylinder plate adjusts the initial position of the limit block from the swing block. After the control plug is plugged into the connection interface, the stepped structure of the plug cooperates with the bottom of the limit block to restrict the axial movement of the plug.

[0008] Compared with the prior art, the beneficial effects of this utility model are: by setting a set of adjustable length limit blocks on one side of the top of the connection interface, the limit blocks are used to automatically axially position the connection interface after insertion, thereby reducing the risk of instability or detachment of the plug when it is subjected to tension. At the same time, the limit blocks are set to an adjustable length mode, making them suitable for plugs of different sizes to be inserted into the connection interface. Attached Figure Description

Thus, features defined with "first," "second," etc., may explicitly or implicitly include one or more of that feature. In the description of this utility model, unless otherwise stated, "a plurality of" means two or more.

[0016] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0017] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0018] Please see Figures 1-4 A cable interface for an electric-assisted bicycle includes a power source 10 and a connecting wire 11. A connecting interface 13 is provided on one end of the power source 10. A stepped plug 12 is connected to the end of the connecting wire 11. The plug 12 is plugged into the connecting interface 13. A set of positioning members is oscillatingly provided on one side of the top of the connecting interface 13. The positioning members are used to axially position the plug 12 plugged into the connecting interface 13, that is, to prevent the plug 12 from loosening or detaching from the connecting interface 13 when the connecting wire 11 is subjected to tension.

[0019] The positioning component includes a positioning component swing groove 14 opened on the top side wall of the connection interface 13. A set of swing shafts 16 are rotatably connected inside the positioning component swing groove 14. A swing block 15 is fixedly installed in the middle of the swing shaft 16. A rectangular telescopic cylinder plate 19 is installed outward from the swing block 15. A telescopic plate 20 is telescopically arranged inside the telescopic cylinder plate 19 away from the swing block 15. A vertically arranged limit block 18 is installed at the end of the telescopic plate 20. Adjusting the position of the telescopic plate 20 in the telescopic cylinder plate 19 adjusts the initial position of the limit block 18 from the swing block 15. After the control plug 12 is plugged into the connection interface 13, the stepped structure of the plug 12 cooperates with the bottom of the limit block 18 to restrict the axial movement of the plug 12.

[0020] Specifically, the bottom of the limiting block 18 is set with an inclined surface structure on the side away from the connection interface 13. When the plug 12 moves toward the inside of the connection interface 13, the plug 12 contacts the limiting block 18 and passes over the limiting block 18 smoothly using the inclined surface. When the connection interface 13 moves back, the vertical surface inside the limiting block 18 corresponding to the inclined surface blocks it, thereby achieving the positioning of the plug 12 after it is plugged into the connection interface 13.

[0021] In this embodiment of the invention, a rotating hole is provided in the inner wall of the positioning member swing groove 14 corresponding to both ends of the swing shaft 16. The swing shaft 16 is placed inside the rotating hole and rotates and is fitted with a spring 17. When the spring 17 is in a free state, the outer end of the swing block 15 is controlled to tilt downward at a certain angle to ensure that it passes the top side wall of the connection interface 13 after passing the limit block 18. Under the automatic tilting and swinging of the swing block 15, the limit block 18 is controlled to smoothly contact and position with the top side wall of the connection interface 13.

[0022] In one embodiment of the present invention, telescopic grooves 21 are symmetrically provided on both sides of the telescopic plate 20, and a tightening screw 22 is threadedly connected to one side of both sides of the telescopic cylinder plate 19 near the telescopic plate 20. The inner end of the tightening screw 22 extends into the interior of the telescopic cylinder plate 19. By rotating the tightening screw 22, the end of the screw is controlled to contact the telescopic groove 21, thereby restricting the telescopic movement of the telescopic plate 20 in the telescopic cylinder plate 19.

[0023] To increase the friction of the inner surface of the telescopic slide 21, its inner surface is made into a corrugated structure, which increases the sliding resistance between the inner end of the tightening screw 22 and the telescopic slide 21, thereby improving the strength of the tightening screw 22 in restricting the movement of the telescopic plate 20.

[0024] In a preferred embodiment of the present invention, in order to reduce the wear force on the connection interface 13 after the limiting block 18 comes into contact with the connection interface 13, a buffer pad is laid on the side of the limiting block 18 that comes into contact with the connection interface 13.

[0025] The preferred embodiments of the present invention have been described in detail above. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
