Description

Technical Field

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

[0002] Modular transportation of bicycles after leaving 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 machine head and head tube need to be disassembled and transported in batches. After disassembly, since the brake line is in a "broken lotus" 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 scooters packaged in batches, after installation, they also need to re-debug the brake structure of the scooter, 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 modular brake system. When transported to the destination, the consumer only needs to recouple the quick-release female and male connectors before connecting the machine head and the head pipe to directly achieve the factory debugging state without the need for manual adjustment and debugging again.

[0004] Technical solution: To achieve the above-mentioned purpose, a modular brake system of the present invention includes a brake handle, a head, a head pipe, a front wheel frame, and a front wheel brake actuator on a scooter;

[0005] It comprises a brake line of section a and a brake line of section b; the machine head is detachably connected to the head tube; the lower end of the head tube is connected to the upper end of the front wheel frame; the brake line of section a shuttles through a threading channel in the machine head, and the brake line of section b shuttles through a threading channel in the head tube; the ends of the brake line of section a and the brake line of section b that are close to each other are synchronously coupled through a quick-release female-female connector in the connection between the machine head and the head tube, and the ends of the brake line of section a and the brake line of section b that are far away from each other are respectively pulled and connected to the brake handle and the brake line connection end of the front wheel brake actuator.

[0006] Furthermore, the connection between the machine head and the head pipe is locked by a plurality of transverse locking bolts on the basis of a mutually detachable sleeve connection.

[0007] Furthermore, the quick-release female-female connector includes a female head connected to the end of the brake line of section a and a male head connected to the end of the brake line of section b; the female head and the male head are detachably buckled with each other.

[0008] Furthermore, the male head is fixedly connected to section B brake line through a connecting column, and the outer diameter of the connecting column is smaller than the outer diameter of the male head; one side of the female head is provided with a male head slot and a connecting column slot that are connected to each other; in the coupled state, the male head and the connecting column are respectively embedded in the male head slot and the connecting column slot.

[0009] Furthermore, when the male head and the female head are in a coupled state, the outer coaxial movable sleeve of the combined structure formed by the male head and the female head is provided with an anti-drop sleeve.

[0010] Furthermore, an end wall is provided at one end of the anti-drop sleeve away from the brake line of section b, a brake line passing hole is provided at the axis of the end wall, and the end of the brake line of section a movably passes through the brake line passing hole.

[0011] Furthermore, a spring support sleeve is fixed on section a of the brake line, and a thrust spring is provided on the outer sleeve of section a of the brake line between the spring support sleeve and the end wall, and the thrust spring forms an elastic thrust on the end wall of the anti-drop sleeve.

[0012] Furthermore, a fixed sleeve is provided outside the movable sleeve of the brake line of section b, and the fixed sleeve is fixedly connected to the upper end of the inner wall of the head tube through a fixed arm; an electric retractor is fixedly installed parallel to the fixed sleeve, and during normal use of the scooter and when the brake handle is in the released state, the end of the telescopic rod of the electric retractor contacts or gap fits the end face of the female head.

[0013] Beneficial effect: After the manufacturer of the present invention has completed production and debugged the brake system in the assembled state, in order to transport it in a modular manner, the machine head and the head pipe need to be disassembled again and then transported in batches. During disassembly, it is only necessary to decouple and separate the quick-release parent-child connector at the connection between the machine head and the head pipe to achieve complete separation of the machine head and the head pipe. The section a brake line and the section b brake line respectively follow the separated machine head and head pipe, thereby modularizing the brake system. When transporting to the destination, the consumer only needs to recouple the quick-release parent-child connector before connecting the machine head and the head pipe to directly reach the debugging state at the factory without the need for manual adjustment and debugging again.

[0022] The present invention will be further described below in conjunction with the accompanying drawings.

[0023] As attached Figures 1 to 8 A modular brake system as shown Figure 1 and 2 The scooter includes a brake handle 9, a nose 11, a head tube 12, a front wheel frame 14, and a front wheel brake actuator 15. The front wheel brake actuator 15 of this case is a conventional line disc brake structure, characterized in that it also includes a section a brake line 7 and a section b brake line 5; the brake handle 9 is installed on the nose 11, and the lower end of the nose 11 is detachably connected to the upper end of the head tube 12; the lower end of the head tube 12 is connected to the upper end of the front wheel frame 14 through a folding structure 13; the section a brake line 7 shuttles through the threading channel in the nose 11, and the section b brake line 5 shuttles through the threading channel in the head tube 12; the ends of the section a brake line 7 and the section b brake line 5 that are close to each other are synchronously coupled in the connection 8 of the nose 11 and the head tube 12 through a quick-release female-female connector 6, and the ends of the section a brake line 7 and the section b brake line 5 that are far away from each other are respectively pulled to connect the brake handle 9 and the brake line connection end of the front wheel brake actuator 15.

[0024] The connection 8 between the head 11 and the head pipe 12 is based on a mutually detachable sleeve connection. Figure 2 , locked by a plurality of transverse locking bolts 16; when the manufacturer has completed production and debugged the brake system in the assembled state, for modular transportation, the machine head 11 and the head tube 12 need to be disassembled again and transported in batches. During disassembly, it is only necessary to decouple and separate the quick-release female-female connector 6 at the connection between the machine head 11 and the head tube 12 to achieve complete separation of the machine head 11 and the head tube 12. The section a brake line 7 and the section b brake line 5 respectively follow the separated machine head 11 and the head tube 12, thereby modularizing the brake system.

[0025] When transported to the destination, the consumer only needs to recouple the quick-release female-female connector 6 before connecting the head 11 and the head pipe 12 to directly achieve the factory debugging state without manual adjustment and debugging again.

[0026] like Figures 3 to 7 As shown, the quick-release female-female connector 6 includes a female head 24 coaxially fixedly connected to the end of the section a brake line 7, and a male head 23 coaxially connected to the end of the section b brake line 5; the female head 24 and the male head 23 are detachably buckled with each other.

[0027] The male connector 23 is fixedly connected to the brake line 5 of section b through a connecting column 26, and the outer diameter of the connecting column 26 is smaller than the outer diameter of the male connector 23; one side of the female connector 24 is provided with a male connector slot 18 and a connecting column slot 19 which are connected to each other, and the outer contours of the male connector 23 and the connecting column 26 are respectively adapted to the inner contours of the male connector slot 18 and the connecting column slot 19; in the coupled state, the male connector 23 and the connecting column 26 are respectively embedded in the male connector slot 18 and the connecting column slot 19.

[0028] like Figure 4 and 6 When the male connector 23 and the female connector 24 are in a coupled state, the outer coaxial movable sleeve of the combined structure formed by the male connector 23 and the female connector 24 is provided with an anti-drop sleeve 17 .

[0029] An end wall 22 is provided at the end of the anti-detachment sleeve 17 away from the brake line 5 of section b, and a brake line passing hole 51 is provided at the axis of the end wall 22, and the end of the brake line 7 of section a can be movably passed through the brake line passing hole 51; a spring support sleeve 20 is fixedly provided on the brake line 7 of section a by interference fit or welding, and a thrust spring 21 is provided on the outer sleeve of the brake line 7 of section a between the spring support sleeve 20 and the end wall 22, and the thrust spring 21 forms an elastic thrust on the end wall 22 of the anti-detachment sleeve 17, so that the anti-detachment sleeve 17 is stably sleeved outside the combined structure formed by the male head 23 and the female head 24, thereby avoiding the mutual decoupling and separation of the male head 23 and the female head 24; when it is necessary to decouple and separate the quick-release female-sub connector 6, it is only necessary to push the anti-detachment sleeve 17 along the axial direction by hand and overcome the elastic force of the thrust spring 21, so that the anti-detachment sleeve 17 is relatively displaced along the axial direction and separated from the combined structure formed by the male head 23 and the female head 24, as shown in FIG. Figure 5 .

[0030] Based on the above structure, this scheme also proposes the following improved structure: Figure 8 As shown, the outer movable sleeve of the b-section brake line 5 is provided with a fixed sleeve 43, and the fixed sleeve 43 is fixedly connected to the upper end of the inner wall of the head tube 12 through a fixed arm; an electric telescopic device 42 is fixedly installed in parallel on the fixed sleeve 43. During normal use of the scooter, and when the brake handle 9 is in the released state, the end of the telescopic rod 41 of the electric telescopic device 42 just contacts or fits the end face of the female head 24 with clearance, and the telescopic movement of the electric telescopic device 42 is remotely controlled by the controller; when the user temporarily parks the scooter, or the parents do not want the child to use the temporarily parked scooter, the telescopic rod 41 of the electric telescopic device 42 is controlled to extend and push the female head 24 upward, so that the female head 24 moves upward with the male head 23, and the a-section brake line 7 is adaptively bent, thereby pulling the b-section brake line 5 to pull the brake line connection end of the front wheel brake actuator 15 alone, so that when the user does not squeeze the brake handle 9, the front wheel brake actuator 15 automatically performs a braking action, which plays the function of locking the vehicle in the parking state.

[0031] 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 principle of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
