Description

Technical Field

[0001] The present invention relates to the field of bicycle brake equipment, and more particularly to a tandem brake system. Background Art

[0002] Bicycles, as a common means of transportation, are increasingly popular, especially with growing awareness of environmental protection and health. For children, bicycles are not only a means of daily transportation but also an effective way to exercise and enhance physical fitness. However, the safety of children's bicycles has always been a concern, especially regarding the function and design of the brake system. A stable and reliable brake system not only ensures children's riding safety but also improves comfort and control during riding.

[0003] Existing brake systems suffer from a long brake stroke, which is particularly noticeable when used by children. Children's hands are smaller, and they often require a longer brake stroke to achieve effective braking. Consequently, these brake systems can result in a delayed brake response, increasing the risk of failure to stop the vehicle. In an emergency, due to children's limited hand strength, the longer brake lever stroke may prevent them from braking in time, compromising riding safety. Utility Model Content

[0004] In order to improve riding safety, the present application provides a tandem braking system.

[0005] In the first aspect, the present application provides a tandem brake system that adopts the following technical solutions:

[0006] A tandem braking system comprising:

[0007] A brake module, a brake line and a brake handle; the brake handle is connected to the brake line and connected to the brake module through the brake line for braking movement; the brake module includes a first brake module and a second brake module arranged on both sides of the same wheel; the brake line is fixedly connected to the first brake module and performs braking movement on the side where the first brake module is located. After being connected to the first brake module, the brake line also extends to the second brake module, so that the brake line is connected to the second brake module, and the brake line is also used to drive the second brake module to perform braking movement.

[0008] By adopting the above technical solution, a brake cable is fixedly connected to the first brake module and then connected in series to the second brake module. When braking both sides of the wheel through the first brake module and the second brake module, there is no gap in the brake cable travel, which reduces the brake handle travel during braking, ensuring that children can achieve rapid braking with only a short brake handle movement, adapting to the needs of children with smaller hand strength, and even in an emergency, it can ensure that children can effectively control the bicycle to stop, avoiding the phenomenon of failure to brake due to excessively long brake travel, thereby enhancing riding safety.

[0009] Preferably, the first brake module and the second brake module both include a guide base connected to the vehicle frame, a brake member arranged at one end of the guide base, and a driving mechanism movably mounted on the guide base and driving the brake member to move. The wire tube of the brake line is fixed on the guide base, and the wire core is connected to the driving mechanism to drive the driving mechanism through the brake line, so that the brake member realizes braking movement.

[0010] By adopting the above technical solution, when the rider needs to brake, by pulling the brake cable, the drive mechanism can be driven to operate, and then the brake part can be driven to achieve braking movement. Since the brake cable is directly connected to the drive mechanism, the braking action can be transmitted quickly, achieving a fast-response braking effect. The stable connection of the guide base and the close cooperation between the drive mechanism and the brake part ensure the stability and reliability of the entire braking system.

[0011] Preferably, the brake line includes a first brake line segment and a second brake line segment; the first brake line segment and the second brake line segment are connected to form a whole brake line; the first brake line segment and the second brake line segment respectively include a wire tube and a wire core, and the wire core is longer than the wire tube.

[0012] By adopting the above technical solution, the brake line is divided into a first brake line segment and a second brake line segment, and a connecting component is used to achieve a stable connection between the two brake modules. The first brake line segment and the second brake line segment form a whole brake line. Each brake line segment includes a wire tube and a wire core, and the wire core is longer than the wire tube. The wire core can move freely in the wire tube, while ensuring that the wire core can pass through the wire tube and be connected to the drive mechanism when needed, ensuring the stability and efficiency of the brake line in transmitting force, and ensuring that the brake line will not deviate or twist when transmitting force, thereby enhancing the accuracy of braking, achieving rapid vibration, and improving the safety of children when using it.

[0013] Preferably, one end of the brake wire is fixed on the guide base, and the wire core is connected to the driving mechanism, so that the driving mechanism is driven by the brake wire to make the brake member realize braking movement, specifically including:

[0014] The driving mechanism includes a transmission part and a driving part. The transmission part is fixedly connected to the brake line, and the driving part drives the brake part to move toward the wheel to realize the braking movement; the transmission part is provided with a fastener, and a threading hole is provided on the fastener for the brake line to pass through. After the brake line is passed through, it is fixed on the fastener to realize the fixation of the brake line.

[0015] By adopting the above technical solution, one end of the brake line is fixed on the guide base, and the other end is firmly connected to the transmission part through fixing screws and nuts, thereby enhancing the stability of the brake line and reducing the loosening or falling off that may occur during use. The fixed connection between the transmission part and the brake line and the close cooperation between the drive part and the brake part enable the braking action to be quickly and accurately transmitted to the brake part, thereby achieving an efficient braking effect.

[0016] Preferably, a clamping groove for the brake line to be clamped is provided at the bottom of the guide base of the first brake module. After the brake line is fixed to the fastener, it extends to the second brake module and passes through the clamping groove and is connected to the second brake module.

[0017] By adopting the above technical solution, a snap-in groove is set at the bottom of the guide base of the first brake module, which realizes the snap-in and extension of the brake line. By setting the snap-in groove, the connection between the first brake module and the second brake module is more stable, reducing the shaking or falling off of the brake line during driving, thereby improving the stability of the entire brake system, ensuring the smooth transmission of the braking action between the two brake modules, reducing the resistance during the transmission process, and thus improving the response speed and braking efficiency of the brake system.

[0018] Preferably, a slot for the brake line to pass through is provided on the top of the guide base, and the brake line passes through the top of the guide base and is connected to the transmission part.

[0019] By adopting the above technical solution, a slot is opened at the top of the guide base, so that the brake line can pass through more neatly and orderly and connect with the transmission part, which is beneficial to reduce the shaking and friction of the brake line during driving, thereby increasing the service life of the brake line. At the same time, it can effectively prevent the brake line from loosening or shifting during use, and ensure that the brake line will not deviate when transmitting force, further improving the safety during braking.

[0020] Preferably, a connector is further provided at the end of the wire tube, and the connector is detachably connected to the wire tube;

[0021] The wire tube is fixed to the guide base via a connector.

[0022] By adopting the above technical solution, the wire pipe and the guide base are fixed through the connecting parts, so that the wire pipe can be flexibly installed on brake modules of different models and specifications according to actual needs, thereby improving the adaptability and versatility of the product. The connecting parts and the wire pipe adopt a detachable connection method. When the wire pipe is worn or damaged, it can be easily replaced without large-scale disassembly of the entire brake system, which greatly reduces the maintenance cost and difficulty.

[0023] Preferably, the brake system is arranged adjacent to the front wheels or the rear wheels of the vehicle.

[0024] By adopting the above technical solution, the braking system is arranged adjacent to the front or rear wheels of the vehicle, which can shorten the braking distance, thereby ensuring that children can quickly brake the wheels and improve riding safety. At the same time, arranging the braking system near the wheels is conducive to the compactness and rationality of the entire vehicle structure.

[0025] Preferably, a bicycle is also included, wherein the bicycle comprises wheels, a frame and a brake system, and the brake system is as described in any one of the first aspects.

[0026] In summary, this application includes at least one of the following beneficial technical effects:

[0027] 1. After a brake cable is fixedly connected to the first brake module and then connected in series to the second brake module, there is no gap in the brake cable travel when braking both sides of the wheel through the first and second brake modules. The brake handle travel is reduced during braking, ensuring that children can achieve rapid braking with only a short brake handle movement. This adapts to the needs of children with smaller hand strength. Even in an emergency, it can ensure that children can effectively control the bicycle to stop, avoiding the phenomenon of the bicycle being unable to stop due to excessive brake travel, and enhancing riding safety.

[0033] The following is combined with Figure 1-4 This application is described in further detail.

[0034] The embodiment of the present application discloses a tandem brake system. Figure 1The tandem brake system includes a brake module 1 and a brake line 2. The brake module 1 includes a first brake module 11 and a second brake module 12 arranged on both sides of the wheel. The first brake module 11 and the second brake module 12 brake the wheel from both sides. The first brake module 11 and the second brake module 12 have the same structure and are arranged symmetrically.

[0035] Reference Figure 2 The brake line 2 is connected and fixed to the first brake module 11, and brakes the wheel on the side where the first brake module 11 is located. After the brake line 2 is fixed, it extends outward, wraps around the wheel and is connected and fixed to the second brake module 12. The first brake module 11 and the second brake module 12 are connected in series through the brake line 2, and brake the wheel on the side where the second brake module 12 is located, thereby reducing the braking stroke and improving the effective braking effect, thereby improving the safety of children when using it.

[0036] Reference Figure 1 Specifically, the brake line 2 includes a first brake line segment 22 and a second brake line segment 23. One end of the first brake line segment 22 is connected to the brake handle and the other end is connected to the guide base 111 of the first brake module 11, and is retracted by the movement of the brake handle; the two sections of the second brake line segment 23 are respectively connected to the first brake module 11 and the second brake module 12, and the two sections of the brake line are connected to form a whole brake line 2.

[0037] Reference Figure 3 、 Figure 4 The first brake module 11 includes a guide base 111 connected to the vehicle frame. The guide base 111 is used to provide positioning support and ensure the stability of the first brake module 11, thereby better performing the braking operation. The guide base 111 can be made of aluminum alloy, steel, or other materials. In this embodiment, the guide base 111 is made of aluminum alloy, which is lightweight and high in strength. A slot 1112 for the brake cable 2 to be engaged is provided at the top of the guide base 111. A coupling slot 1111 for the brake cable 2 to be engaged is also provided at the bottom of the guide base 111. The coupling slot 1111 is used to secure the brake cable 2 to the guide base 111, ensuring the stability and reliability of the brake cable 2. The coupling slot 1111 is configured to be arc-shaped, with the specific arc being 0.6-0.7 times the full circle, allowing the brake cable 2 to be smoothly inserted and clamped, thereby ensuring that the brake cable 2 does not slip out. In this embodiment, the coupling slot 1111 can be configured as a notched circular tube welded to the bottom of the guide base 111.

[0038] Reference Figure 1 The first brake module 11 includes a brake member 112 disposed at one end of the guide base 111. The brake member 112 is used to brake the wheel to ensure that the wheel stops.

[0039] In addition, the first brake module 11 also includes a drive mechanism 113 movably mounted on the guide base 111 and driving the brake member 112 toward the wheel hub. Drive mechanism 113 is a mechanical drive mechanism 113, and its drive structure includes a transmission unit 1131 and a drive unit 1132. Transmission unit 1131 includes a fastener 11311, which defines a through hole 113111 for the brake cable 2 to pass through. Through hole 113111 is a through hole with a diameter of 2 mm, which precisely matches the diameter of the brake cable 2, allowing the brake cable 2 to pass through and be secured.

[0040] The drive unit 1132 is connected to the brake member 112 via gear teeth. Specifically, the brake member 112 is provided with a rack 1121 that matches the gear. The brake member 112 is tilted relative to the guide base 111. When the drive unit 1132 rotates (e.g., driven by rotational force), the gears drive the brake member 112 toward the wheel hub, achieving braking. The gear teeth of the drive unit 1132 can be made of high-strength materials such as steel or brass to ensure resistance to damage and a long service life.

[0041] Reference Figure 1 The brake line 2 is wrapped with a wire tube 21 on the outside of the section connecting the first brake module 11 and the second brake module 12. The brake line 2 is slidingly arranged with the inner wall of the wire tube 21. One end of the wire tube 21 is fixed at the card groove 1111 of the guide base 111 of the first brake module 11, and the other end is fixed at the card groove 1112 of the guide base 111 of the second brake module 12. The position of the wire tube 21 remains unchanged during braking. The wire tube 21 is made of highly elastic natural rubber material and has excellent wear resistance and good weather resistance. The wire tube 21 can effectively prevent the brake line 2 from being eroded by the external environment during use. The wire tube 21 is fixedly connected to the guide base 111 of the first brake module 11 and the second brake module 12 through a connector 211.

[0042] Connector 211 is made of stainless steel and secured with screws. When the cable conduit 21 becomes worn or damaged, it can be easily replaced by removing the connector 211, eliminating the need for extensive disassembly of the entire brake system. This not only extends the service life of the cable conduit 21 and reduces replacement costs, but also simplifies maintenance. This design not only enhances the ease of installation and replacement of the cable conduit 21, but also significantly improves the overall stability and safety of the brake system.

[0043] In another embodiment of the present application, Figure 1-2 The figure shows a bicycle, which is composed of wheels, a frame and a brake system. Of course, the bicycle may also have some other components, and the specific form of each component can be as shown in any other prior art. For the sake of simplicity, this application will not provide redundant descriptions. The brake system of the bicycle includes the above Figure 1-4As shown, this application will not be repeated here.

[0044] Those skilled in the art will appreciate that the brake system in this solution can be applied to any vehicle braking in addition to the bicycle described above. This application does not impose any restrictions on this.

[0045] The implementation principle of a tandem brake system in an embodiment of the present application is: after a brake line is fixedly connected to the first brake module, it is connected in series to the second brake module. When braking on both sides of the wheel through the first brake module and the second brake module, there is no gap in the brake line travel, which reduces the brake handle travel during braking, ensuring that children only need a short brake handle movement to achieve quick braking, adapting to the needs of children with smaller hand strength, and even in an emergency, it can ensure that children can effectively control the bicycle to stop, avoiding the phenomenon of failure to brake due to excessively long brake travel, thereby enhancing riding safety.

[0046] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
