Description

Technical Field

[0001] This utility model relates to the field of scooter cable technology, specifically a cable for a two-to-two structure scooter. Background Technology

[0002] As a common short-distance transportation tool, the reliability and synchronization of the braking system of a scooter directly affect riding safety. Some mid-to-high-end scooter models employ a dual rear wheel design to improve riding stability, which requires the braking system to apply braking force to both rear wheels simultaneously and synchronously. Traditional scooter braking systems often use steel cables as the transmission medium, with the rear wheel brake activated by operating the handbrake handle.

[0003] Currently, the brake cables of most scooters on the market adopt a "one-to-one" or "one-to-two" structure, meaning that a single control end is connected to one or two actuator ends. While the "one-to-two" structure can achieve single-point control of both brakes, in actual use, it only allows for single-sided operation to control the front and rear braking. This means operation is only possible on the side with the brake handle. When the rider needs to switch hands, the same braking effect cannot be achieved, significantly reducing operational convenience. This design flaw limits the rider's operational flexibility and may affect the timeliness of braking in emergency situations. Utility Model Content

[0004] The purpose of this invention is to provide a cable in a two-to-two structure scooter to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: A cable in a two-to-two structure scooter includes The three-way connector has a double-ended flexible hose fixedly connected to one end and two single-ended flexible hoses fixedly connected to the other end. The tee connector is equipped with a synchronization mechanism inside; Both the double-ended hose and the single-ended hose have a fixing mechanism at the end away from the tee connector; The fixing mechanism works in conjunction with the synchronization mechanism.

[0006] Preferably, the synchronization mechanism includes two steel wire ropes slidably connected in a double-ended hose and two steel wire ropes slidably connected in two single-ended hoses. The adjacent ends of the two steel wire ropes slidably connected in a tee joint and fixedly connected by a connector. The adjacent ends of the two steel wire ropes slidably connected to the connector are also fixedly connected to the connector. Preferably, the fixing mechanism includes a mounting sleeve fixedly connected to the end of the double-ended hose and the single-ended hose away from the tee connector. The end of the mounting sleeve is fixedly connected to a threaded part. An adjusting ring is provided on the outside of the threaded part. A limiting ring is fixedly connected to the root of the threaded part. The adjusting ring is threadedly connected to the external threaded part and forms an axial constraint with the limiting ring. Preferably, both the first and second wire ropes have integrally formed post heads at their ends; Preferably, the two single-ended hoses are of different lengths, and the internal steel wire ropes are also of different lengths. Preferably, a pair of rolling shafts are provided on both sides of the inner side of the tee connector near the single-ended hose, and a shaft pin is provided on the inner wall of the tee connector near the single-ended hose. Each pair of rolling shafts is sleeved on the shaft pin through a bearing and makes rolling contact with a steel wire rope.

[0007] Compared with the prior art, the beneficial effects of this utility model are: This two-to-two structure scooter cable, through the use of the synchronization mechanism inside the three-way connector and the cooperation of double-headed hose and single-headed hose, enables the simultaneous braking action of the front and rear brakes to be independently controlled by the left and right operating ends. This solves the problem that the braking system can only be operated on one side in the existing technology, allowing riders to freely choose the operating side according to their usage habits, and significantly improving the convenience and flexibility of braking operation.

[0011] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0012] like Figure 1-4 As shown, this utility model provides a technical solution: A cable in a two-to-two structure scooter includes a three-way connector 1, one end of which is fixedly connected to a double-ended flexible hose 2, and the other end is fixedly connected to two single-ended flexible hoses 3. The three-way connector 1 has a synchronization mechanism inside, which includes two steel wire ropes 4 slidably connected to the double-ended flexible hose 2, and two steel wire ropes 5 slidably connected to the two single-ended flexible hoses 3. The ends of both steel wire ropes 4 and 5 are integrally formed with post heads 10. The adjacent ends of the two steel wire ropes 4 extend into the three-way connector 1 and are fixedly connected by connectors 11. The adjacent ends of the two steel wire ropes 5 are also fixedly connected to connectors 11. A fixing mechanism is provided at the end of the double-ended flexible hose 2 and the single-ended flexible hose 3 away from the three-way connector 1. The fixing mechanism includes... The device includes a mounting sleeve 6 fixedly connected to the end of the double-ended hose 2 and the single-ended hose 3 away from the tee connector 1. The end of the mounting sleeve 6 is fixedly connected to a threaded part 7. An adjusting ring 8 is provided on the outside of the threaded part 7. A limiting ring 9 is fixedly connected to the root of the threaded part 7. The adjusting ring 8 is threadedly connected to the external threaded part 7 and forms an axial constraint with the limiting ring 9. The fixing mechanism cooperates with the synchronization mechanism. The two single-ended hoses 3 are of different lengths, and the internal steel wire ropes 5 are also of different lengths. A pair of rolling shafts 12 are provided on both sides of the end of the tee connector 1 closest to the single-ended hose 3. A shaft pin is provided on the inner wall of the end of the tee connector 1 closest to the single-ended hose 3. Each pair of rolling shafts 12 is sleeved on the shaft pin through a bearing and rolls in contact with a steel wire rope 5 respectively. In this embodiment, by using the synchronization mechanism inside the three-way connector 1 in conjunction with the double-ended hose 2 and the single-ended hose 3, the synchronous braking action of the front and rear brakes can be independently controlled by the operating ends on both the left and right sides. This solves the problem that the braking system can only be operated on one side in the prior art, allowing riders to freely choose the operating side according to their usage habits, and significantly improving the convenience and flexibility of braking operation.

[0013] Furthermore, the rolling engagement between the rolling shaft 12 inside the three-way connector 1 and the steel wire rope 5 effectively reduces the frictional resistance of the steel wire rope when turning, ensuring that the brakes on both sides can achieve a completely synchronized braking effect, and improving the reliability and response speed of the braking system.

[0014] Working principle: When the operator pulls any one of the steel wire ropes 4 in the double-ended hose 2, the steel wire rope 4 drives the two steel wire ropes 5 to move synchronously through the connector 11. Since the two steel wire ropes 5 change their direction of movement through the rolling shaft 12 and are connected to the steel wire rope 5 in the single-ended hose 3, the rolling contact of the rolling shaft 12 effectively reduces the frictional resistance of the steel wire ropes 5, allowing the two steel wire ropes 5 to move synchronously with the same displacement, thereby simultaneously driving the two rear wheel brake assemblies to achieve synchronous braking; the fixing mechanism connects the double-ended hose 2 and the single-ended hose 3 to the handlebar braking mechanism and the rear wheel brake mechanism of the scooter respectively through the mounting sleeve 6. The wheel brake assembly is connected, and the rotating adjusting ring 8 can move axially along the threaded part 7. Through cooperation with the limiting ring 9, the tightness of the brake cable can be precisely adjusted to ensure that the braking system is always in the best working condition. Since the two single-ended hoses 3 are designed with one long and one short, and the internal steel wire ropes 5 are correspondingly set to one long and one short, the cable can adapt to the different installation positions of the rear wheel brake assemblies on both sides of the scooter. The post heads 10 at the ends of the steel wire ropes 4 and 5 are reliably fixed to the connecting parts of the brake assembly by a snap-fit ​​method to prevent the steel wire ropes from falling off during braking and to ensure the safety and reliability of the braking system.
