[0023] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of the present application.

[0024] Refer to Figures 1-5 , including a front - rear linkage brake system and a bicycle applying the brake system. In addition to applying the brake system, the bicycle further includes a wheel 4 and a frame 1.

[0025] In an embodiment of the present application, the front - rear linkage brake system may specifically include a brake lever 2, a brake cable 3, a first brake module 5, and a second brake module 6. The brake cable 3 connects the brake lever 2, the first brake module 5, and the second brake module 6 in series. The brake lever 2 is used to drive the first brake module 5 to perform a braking movement through the brake cable 3; the first brake module 5 further includes a linkage mechanism 51, and the linkage mechanism 51 is used to synchronize at least part of the braking movement of the brake cable 3 and the first brake module 5 to the second brake module 6, thereby driving the second brake module 6 to perform a braking movement.

[0026] By adopting the above - mentioned technical solution, when the bicycle needs to brake, the user can press the brake lever 2 with one hand, and under the action of the brake cable 3, pull the first brake module 5 on the front wheel, so that the first brake module 5 performs a braking movement. When the first brake module 5 performs a braking movement, it will drive the brake cable 3 connected to the second brake module 6 to move, so that the second brake module 6 performs a braking movement, achieving the purpose of braking two wheels 4 with a single brake lever 2.

[0027] Specifically, since the first brake module 5 is provided with a linkage mechanism 51, the braking movement of the first brake module 5 will drive the brake cable 3 connected to the second brake module 6 behind to tighten through the linkage mechanism 51, thereby also realizing the braking movement of the second brake module 6. For the braking movement process of the second brake module 6, it is exactly the same as the braking movement process of the first brake module 5, and the present application will not elaborate here.

[0028] It should be noted that the above first braking module 5 and second braking module 6 are only for distinguishing different braking modules, and do not have a primary-secondary relationship or a front-back relationship like the first and the second.

[0029] In the embodiments of the present application, the first braking module 5 is used to be arranged adjacent to the front wheel or the rear wheel of the bicycle. The present application has no limitation on placing the first braking module 5 with a linkage mechanism on the front wheel and the rear wheel of the vehicle. It can be set arbitrarily according to actual needs. As long as a braking module of a bicycle includes a mechanism for linking the movement of another braking module, it is within the protection scope of the present application.

[0030] Similarly, the first braking module 5 and the second braking module 6 are respectively arranged on different wheels 4 of the same bicycle. Obviously, the first braking module 5 and the second braking module 6 have a physical connection relationship, and the first braking module 5 and the second braking module 6 can only be arranged on the same bicycle. When the first braking module 5 is arranged on the front wheel, the second braking module 6 is arranged on the rear wheel of the vehicle.

[0031] Of course, in some special examples, it may be applied in the case of a vehicle with three wheels, including two front wheels and one rear wheel. Or, one front wheel and two rear wheels. In this case, when the braking module arranged on one wheel can drive the braking module on another wheel to achieve a braking movement, or drive the braking modules on the other two wheels to achieve a braking movement, it is also within the scope of the present application. It can be known that for the above solutions, as long as the brake wire 3 connected to the linkage mechanism 51 is connected to two wheels 4 at the same time.

[0032] Figure 2 This utility model provides a schematic diagram of a brake wire including a front-back linkage braking system. As Figure 2 shown, the brake wire 3 mentioned in the above embodiments of the present application actually includes a first brake wire segment 31 and a second brake wire segment 32. Here, the first brake wire segment 31 and the second brake wire segment 32 can be a completely disconnected structure or an integral one.

[0033] In a specific example below, the brake wire 3 is completely disconnected, that is, the first brake wire segment 31 is used to connect the brake lever 2 and the first braking module 5, and the second brake wire segment 32 is used to connect the linkage mechanism 51 and the second braking module 6.

[0034] In the embodiments of the present application, the first braking module 5 can be any traditional brake. In the specific embodiments of the present application, a V-brake is specifically used for illustration. Refer to Figure 3, The V-brake includes a fixed end 56 connected to the vehicle frame, and the fixed end is located on the first brake arm 53 and the second brake arm 54 on the left and right sides of the vehicle. Among them, a common brake block 57 is provided on the first brake arm 53, and a linkage mechanism 51 is provided on the other brake arm 54. A brake block 58 is provided on the side of the linkage mechanism 51 close to the wheel 4.

[0035] Among them, the first brake line segment 31 drives the two brake arms 53 / 54 through an elastic drive structure 55, and drives the brake blocks 57 / 58 to brake the wheel. Since the brake block 58 is provided on the linkage mechanism 51, when the brake block 58 contacts the wheel 4, the brake block 58 will drive the second brake line segment 32 connected to the brake block 58 to move through the linkage mechanism 51, realizing the braking of the second brake module 6.

[0036] Figure 4 A linkage mechanism provided in this application includes a housing 511 and a slider 515. The interior of the housing 511 includes a sliding space 512 that matches the slider 515, and the slider 515 is provided in the sliding space 512. The aforementioned brake block 58 provided on the second brake module 6 is specifically provided on the slider 515. At the same time, an opening space 513 passing through the brake block 58 is provided on the housing 511.

[0037] At the same time, the second brake line segment 32 is also connected to the slider 515 of the linkage mechanism 51. The extending direction of the second brake line segment 32 is the same as the moving direction of the slider 515, and the second brake line 32 passes through the housing 511 and is connected to the second brake module 6.

[0038] In the embodiment of this application, an elastic element 516 is also provided between the slider 515 and the housing 511. In a specific example, the elastic element 516 can be a tension spring or a compression spring. For example, when the direction of the elastic element 516 is the same as the direction of the second brake line segment 32, the elastic element 516 is a tension spring; when the direction of the elastic element 516 is different from the direction of the second brake line segment 32, the elastic element 516 is a compression spring.

[0039] Figure 5 The figure shows a schematic diagram of the structure of a brake module in an embodiment of this application. Hereinafter, taking the second brake module 6 as an example for illustration, the second brake module 6 mainly includes a mounting base 61, a drive mechanism 62, a linkage mechanism 63, and a brake block 64. Among them, the mounting base 61 is the base part of the entire second brake module 6, and it is fixedly connected to the bicycle frame 1. Of course, it may also be movably connected to adjust the position of the second brake module 6. Structures such as the drive mechanism 62, the linkage mechanism 63, and the brake block 64 are all provided on the mounting base 61.

[0040] In a specific example of the embodiment of the present application, the linkage mechanism 63 is fixedly arranged relative to the mounting base 61, the brake block 64 is slidably arranged relative to the mounting base 61 and the linkage mechanism 51, and the driving mechanism 62 is rotatably arranged relative to the mounting base 61; the first brake wire segment 31 is connected to the driving mechanism 62 and drives the driving mechanism 62 to rotate, the driving mechanism 62 is connected to the brake block 64, and the rotational movement of the driving mechanism 62 will drive the sliding movement of the brake block 64.

[0041] In a particularly specific example, the driving mechanism 62 adopts a mechanical driving mechanism, and the driving structure 62 includes a transmission part and a driving part. The transmission part includes a fastener, and a through hole for the brake wire to pass through is formed in the fastener. In one example, the through hole is a through hole with a diameter of 2 mm, which just matches the diameter of the second brake wire 32, so that the second brake wire 32 can pass through and be fixed smoothly.

[0042] The driving part is connected to the brake block 64 through gear teeth. Specifically, the brake block 64 is provided with a rack adapted to the gear, and the brake block 64 is inclined relative to the mounting base 61. When the driving part (for example, driven by a rotational force) rotates, the brake block 64 is driven by the gear to move towards the wheel 4 to achieve braking. In one example, the gear tooth material of the driving part can adopt high-strength materials such as steel or brass to ensure that it is not easily damaged and has a long service life.

[0043] Those skilled in the art can know that the above specific structural settings of the second brake module 5 can not only be used for the second brake module 6, but also for the first brake module 5. For the convenience of description in the embodiment of the present application, repeated descriptions are made.

[0044] Those skilled in the art can also know that the above various specific structural descriptions of the first brake module 5 and the second brake module 6 are only examples of the specific embodiments of the present application. They can be used for various brake modules. The various specific structural designs are completely a specific description given based on the need to fully disclose the embodiments. Those skilled in the art can also give many other different specific implementation manners.

[0045] For such a setting method, on the one hand, it can reduce the difficulty of installing the device. But more importantly, it can enable the first braking module 5 to achieve a certain degree of braking movement, and then the second braking module 6 can enter the braking movement. It can be imagined that the brakes of a bicycle include ordinary deceleration requirements and stop requirements. Under the deceleration requirement, only a relatively light force is required to achieve braking. At this time, if the front and rear wheels are braked simultaneously, the vehicle may stop. Therefore, this problem can be avoided through the above-mentioned length setting. When the vehicle only needs to decelerate, only a relatively light force is required to achieve braking. At this time, the first braking module 5 brakes. Since there is some redundant line segment in the part where the second braking line segment 32 is connected to the first braking module 5, the second braking module 6 will not brake at this time. When it is necessary to stop the vehicle and the braking force is increased, at this time, the moving distance of the brake block 53 or the driving mechanism 52 in the first braking module 5 exceeds the redundancy amount. At this time, the second braking module 6 participates in braking simultaneously, achieving a rapid stop of the vehicle.

[0046] In another embodiment of the present application, as shown in the figure, a bicycle is provided. The bicycle is composed of components such as a wheel 4, a frame 1, and a braking system. Of course, the bicycle may also have some other components. The specific forms of each component can be as shown in any other existing technologies. For the sake of simplicity of the content of the present application, no redundant description will be made here. The braking system of the bicycle is as shown in the previous embodiment, and no repeated description will be made here.

[0047] In the description of the present utility model, it should be noted that unless otherwise clearly specified and limited, terms such as "installation", "provided with", "connection", etc. should be understood in a broad sense. For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific situations.

[0048] The above are only the preferred embodiments of the present application and are not used to limit the present application. Although the present application has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
