Description

Technical Field

[0001] This utility model relates to electric-assisted bicycles, and more particularly to a charging interface structure for electric-assisted bicycles. Background Technology

[0002] With the development of new electric-assist bicycle technology, the location of the charging port is generally determined by the installation position of the battery on the frame. The charging port is usually designed on the front right side of the downtube, or on the bottom left or rear side of the center tube. The charging connector is installed by setting a charging cut. In addition, some electric-assist bicycles have a charging port design on the motor hook. All of the above charging interface structures generally have problems such as exposed interfaces, difficulty in wiring, and insufficient waterproofing and wire protection. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide an electric-assisted bicycle charging interface structure with better waterproof performance and reasonable cable layout, in order to address the shortcomings of the existing technology.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution.

[0005] An electric-assisted bicycle charging interface structure includes a pivot bearing support, a screw sleeve, a fixing nut, and a charging connector. The pivot bearing support has a screw through hole, the screw sleeve passes laterally through the screw through hole, and the fixing nut is screwed onto the end of the screw sleeve to fix the charging connector in the screw through hole. The fixing nut has a plug clearance hole corresponding to the charging connector. The charging connector includes a lead wire, and the side of the screw sleeve has a lead wire through hole through which the lead wire passes.

[0006] Preferably, the device includes a lower fork, the front end of which is provided with two hinge joints, each hinge joint having a hinge hole. Both ends of the screw sleeve pass through the two hinge holes respectively, and the end of the screw sleeve away from the fixing nut is provided with a stop ring. The stop ring and the fixing nut respectively abut against the outer sides of the two hinge joints.

[0007] Preferably, two bearings are fitted on the outer side of the screw sleeve, and the bearings are sandwiched between the screw sleeve and the inner wall of the screw through hole.

[0008] Preferably, the inner wall of the screw sleeve is formed with an inner stepped ring, and the edge of the charging connector is formed with an outer stepped ring, the outer stepped ring being clamped between the fixing nut and the inner stepped ring.

[0009] Preferably, a charging port cover is detachably connected inside the fixing nut.

[0010] In the electric-assisted bicycle charging interface structure disclosed in this utility model, the frame of the electric-assisted bicycle includes a pivot bearing support, a fork, and a down tube. The down tube is used to install the battery. A screw sleeve is horizontally installed in the screw through hole on the pivot bearing support. The screw sleeve enables a hinged relationship between the fork and the pivot bearing support. At the same time, the charging connector is fixed in the screw through hole by the fixing nut. The fixing nut and the screw through hole protect the charging connector and enhance its waterproof capability. Meanwhile, the lead wire passes through the lead wire through hole and extends to connect to the battery in the down tube. The wiring method is reasonable and allows for reasonable cable layout.

[0016] The present invention will now be described in more detail with reference to the accompanying drawings and embodiments.

[0017] This utility model discloses a charging interface structure for an electric-assisted bicycle, combined with... Figures 1 to 5 As shown, it includes a pivot bearing support 1, a screw sleeve 2, a fixing nut 3, and a charging connector 4. The pivot bearing support 1 has a screw through hole 10. The screw sleeve 2 passes laterally through the screw through hole 10. The fixing nut 3 is screwed onto the end of the screw sleeve 2, and the charging connector 4 is fixed in the screw through hole 10 by the fixing nut 3. The fixing nut 3 has a plug clearance hole 30 corresponding to the charging connector 4. The charging connector 4 includes a lead wire 40. The side of the screw sleeve 2 has a lead wire through hole 20, and the lead wire 40 passes through the lead wire through hole 20.

[0018] In the above structure, the frame of the electric-assisted bicycle includes a pivot bearing support 1, a lower fork 5, and a lower tube 8. The lower tube 8 is used to install the battery. The screw sleeve 2 is horizontally installed in the screw through hole 10 on the pivot bearing support 1. The screw sleeve 2 enables the hinged relationship between the lower fork 5 and the pivot bearing support 1. At the same time, the charging connector 4 is fixed in the screw through hole 10 by the fixing nut 3. The fixing nut 3 and the screw through hole 10 protect the charging connector 4 and enhance its waterproof ability. Meanwhile, the lead wire 40 passes through the lead wire through hole 20 and extends to connect to the battery in the lower tube 8. The wiring method is reasonable and allows for reasonable cable layout.

[0019] Regarding the further structure of the frame, this embodiment includes a lower fork 5. The front end of the lower fork 5 is provided with two hinge joints 50. The hinge joints 50 are provided with hinge holes 51. The two ends of the screw sleeve 2 pass through the two hinge holes 51 respectively. The end of the screw sleeve 2 away from the fixing nut 3 is provided with a stop ring 21. The stop ring 21 and the fixing nut 3 respectively abut against the outside of the two hinge joints 50.

[0020] Under the constraint of the fixing nut 3 and the abutting convex ring 21, the two hinge joints 50 can be clamped on the outside of the pivot bearing support seat 1, thereby achieving a good hinged fit relationship.

[0021] To enable the screw sleeve 2 to rotate at a small angle, in this embodiment, two bearings 6 are sleeved on the outer side of the screw sleeve 2, and the bearings 6 are sandwiched between the screw sleeve 2 and the inner wall of the screw through hole 10.

[0022] For the preferred fixing method of the charging connector 4, please refer to [link / reference]. Figure 3 and Figure 5 The inner wall of the screw sleeve 2 has an inner stepped ring 22, and the edge of the charging connector 4 has an outer stepped ring 41. The outer stepped ring 41 is clamped between the fixing nut 3 and the inner stepped ring 22. Under the fixing action of the fixing nut 3, the outer stepped ring 41 is abutted from the outside. A sealing ring 23 can be clamped between the outer stepped ring 41 and the inner stepped ring 22, thereby achieving waterproof sealing. In addition, since the fixing nut 3 extends into the screw through hole 10 by a certain length, the charging connector 4 can be hidden in the screw through hole 10, resulting in better dustproof and waterproof performance.

[0023] Based on this, a charging port cover 7 is detachably connected inside the fixing nut 3. The charging port cover 7 has a covering function for the screw through hole 10.

[0024] In the aforementioned structure, this invention integrates the internal space design of the shock absorber pivot bearing support sleeve with the charging port device, completely concealing the main charging components (charging connector and wiring harness) within the frame pivot bearing sleeve. Simultaneously, the fixing nut is designed with threads that mate with the inner threads on the left side of the screw sleeve, preventing the charging port from being exposed. Furthermore, in addition to protecting the charging connector, the screw sleeve in this invention also serves as a hinge component for the shock absorber pivot structure, combining protection, waterproofing, and hinge functions.

[0025] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. All modifications, equivalent substitutions or improvements made within the technical scope of the present utility model should be included within the scope of protection of the present utility model.
