Description

Technical Field

[0001] The utility model belongs to the field of modular structures of scooters. Background Art

[0002] Modular transportation of bicycles after they leave the factory can greatly improve the space utilization and efficiency of goods. When the manufacturer has completed production and debugged the brake system in the assembled state, for modular transportation, the scooter handle and riser need to be disassembled and transported in batches. After disassembly, since the brake line is in a "broken lotus root" state, manufacturers generally give up modular batch transportation. If complete batch transportation is to be achieved, the brake line needs to be disassembled; and when consumers receive such batch-packaged scooters, after installation is completed, the brake structure of the scooter needs to be re-debugged, which affects the user experience of the modular transportation mode. Summary of the Invention

[0003] Purpose of the invention: In order to overcome the deficiencies in the prior art, the present invention provides a concealed brake line. When the modular scooter is transported to the destination, the consumer only needs to recouple the parent-child connector before connecting the scooter handle and the riser to directly reach the factory debugging state without the need for manual adjustment and debugging again.

[0004] Technical solution: To achieve the above-mentioned purpose, the utility model provides a hidden brake cable, comprising a first brake cable and a second brake cable; the first brake cable and the second brake cable are synchronously coupled at their respective ends adjacent to each other via a male-female connector;

[0005] The parent-child connector includes a coupling head a connected to the end of the first brake line and a coupling head b connected to the end of the second brake line; the coupling head a and the coupling head b are detachably coupled to each other.

[0006] Furthermore, the B coupling head is fixedly connected to the second brake line through a connecting column, and the outer diameter of the connecting column is smaller than the outer diameter of the B coupling head; one side of the A coupling head is provided with a B coupling head slot and a connecting column slot that are connected to each other; in the coupled state, the B coupling head and the connecting column are respectively embedded in the B coupling head slot and the connecting column slot.

[0007] Furthermore, when the coupling head b and the coupling head a are in a coupled state, the outer coaxial movable sleeve of the combined structure formed by the coupling head b and the coupling head a is provided with an anti-drop sleeve.

[0008] Furthermore, an end wall is provided at one end of the anti-drop sleeve away from the second brake line, a brake line passing hole is provided at the axis of the end wall, and the end of the first brake line is movable through the brake line passing hole.

[0009] Furthermore, a spring support sleeve is fixed on the first brake line, and a thrust spring is provided on a section of the first brake line sleeve between the spring support sleeve and the end wall. The thrust spring forms an elastic thrust on the end wall of the anti-drop sleeve.

[0010] Furthermore, ends of the first brake line and the second brake line that are away from each other are respectively pulled to connect the brake handle and the brake line connection end of the disc brake.

[0011] Beneficial effect: After the manufacturer has completed production and debugged the brake system in the assembled state, the scooter handle and the riser are disassembled and transported in batches. During disassembly, it is only necessary to decouple and separate the parent-child connectors at the connection between the scooter handle and the riser to completely separate the scooter handle and the riser. The first brake line and the second brake line respectively follow the separated scooter handle and riser, thereby modularizing the brake system. BRIEF DESCRIPTION OF THE DRAWINGS

[0015] The present invention will be further described below in conjunction with the accompanying drawings.

[0016] As attached Figure 1 、 2 3 shows a hidden brake line, the scooter includes a brake handle 9, a scooter handle 11, a riser 12, a scooter frame 14, and a disc brake 15. The disc brake 15 in this case is a conventional line disc brake structure, and also includes a first brake line 7 and a second brake line 5; the brake handle 9 is installed on the scooter handle 11, and the lower end of the scooter handle 11 is detachably connected to the upper end of the riser 12; the lower end of the riser 12 is connected to the upper end of the scooter frame 14 by a folding structure 13; the first brake line 7 shuttles through the threading channel in the scooter handle 11, and the second brake line 5 shuttles through the threading channel in the riser 12; the ends of the first brake line 7 and the second brake line 5 that are close to each other are synchronously coupled by a female-female connector 6 in the connection 8 of the scooter handle 11 and the riser 12, and the ends of the first brake line 7 and the second brake line 5 that are away from each other are respectively pulled to connect the brake handle 9 and the brake line connection end of the disc brake 15.

[0017] The connection 8 between the scooter handlebar 11 and the riser 12 is locked by a plurality of transverse locking bolts on the basis of a mutually detachable sleeve connection; after the manufacturer completes production and debugs the brake system in the assembled state, for modular transportation, the scooter handlebar 11 and the riser 12 need to be disassembled and transported in batches. During disassembly, it is only necessary to decouple and separate the female and male connectors 6 at the connection between the scooter handlebar 11 and the riser 12 to completely separate the scooter handlebar 11 and the riser 12. The first brake line 7 and the second brake line 5 follow the separated scooter handlebar 11 and the riser 12 respectively, thereby modularizing the brake system.

[0018] When transported to the destination, the consumer only needs to recouple the male and female connectors 6 before connecting the scooter handle 11 and the riser 12 to directly achieve the factory debugging state without the need for manual adjustment and debugging again.

[0019] The parent-child connector 6 includes a coupling head a 24 coaxially fixedly connected to the end of the first brake line 7 and a coupling head b 23 coaxially connected to the end of the second brake line 5; the coupling head a 24 and the coupling head b 23 are detachably coupled to each other.

[0020] The b coupling head 23 is fixedly connected to the second brake cable 5 through a connecting column 26, and the outer diameter of the connecting column 26 is smaller than the outer diameter of the b coupling head 23; one side of the a coupling head 24 is provided with a b coupling head slot 18 and a connecting column slot 19 that are connected to each other, and the outer contours of the b coupling head 23 and the connecting column 26 are respectively adapted to the inner contours of the b coupling head slot 18 and the connecting column slot 19; in the coupled state, the b coupling head 23 and the connecting column 26 are respectively embedded in the b coupling head slot 18 and the connecting column slot 19.

[0021] When the coupling head b 23 and the coupling head a 24 are in a coupled state, the outer coaxial movably sleeve of the combined structure formed by the coupling head b 23 and the coupling head a 24 is provided with an anti-drop sleeve 17 .

[0022] The end of the anti-slip sleeve 17 away from the second brake line 5 is provided with an end wall 22, and a brake line passing hole 51 is provided at the axis center of the end wall 22, and the end of the first brake line 7 is movably passed through the brake line passing hole 51; a spring support sleeve 20 is fixedly provided on the first brake line 7 by interference fit or welding, and a section of the first brake line 7 between the spring support sleeve 20 and the end wall 22 is provided with a thrust spring 21. The thrust spring 21 forms an elastic thrust on the end wall 22 of the anti-slip sleeve 17, thereby making the anti-slip sleeve 17 stably sleeved outside the combined structure formed by the b coupling head 23 and the a coupling head 24, thereby preventing the b coupling head 23 and the a coupling head 24 from decoupling from each other; when it is necessary to decouple the parent-child connector 6, it is only necessary to push the anti-slip sleeve 17 along the axial direction by hand and overcome the elastic force of the thrust spring 21, so that the anti-slip sleeve 17 is relatively displaced along the axial direction and disengaged from the combined structure formed by the b coupling head 23 and the a coupling head 24.

[0023] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications should also be regarded as within the scope of protection of the present invention.
