Description

Technical Field

[0001] This utility model relates to the field of tricycle technology, specifically to a linkage braking structure and a tricycle. Background Technology

[0002] With the development of the times, the use of tricycles is becoming more and more popular. As one of the means of transportation in the urban-rural fringe, tricycles are indispensable because some rural roads are still rugged and uneven, so a quick-response braking mechanism is essential to avoid accidents.

[0003] Currently, most commercially available tricycle braking systems use drum brakes, which convert the kinetic energy of the wheel into heat energy through friction between the internal brake drum and brake pads, thereby achieving deceleration and braking. Drum brakes generate relatively weak braking force and have a longer braking distance. In the event of an emergency during operation, the sluggish braking can increase the risk of accidents, resulting in lower safety performance. Utility Model Content

[0004] (a) The technical problem solved by this utility model is: most existing tricycles use drum brakes, which generate weak braking force and have a long braking distance, resulting in low safety performance.

[0005] (II) Technical Solution To solve the above-mentioned technical problems, embodiments of this utility model provide a linkage braking structure for tricycles, including a foot brake, a foot brake cable, a disc brake mechanism, and a drum brake mechanism. The foot brake is connected to the disc brake mechanism, and the disc brake mechanism is connected to the front wheel of the tricycle. The foot brake can drive the disc brake mechanism to provide braking force to the front wheel. The foot brake is also connected to the foot brake cable, which is connected to the drum brake mechanism. The drum brake mechanism is connected to the two rear wheels of the tricycle respectively. The foot brake can drive the drum brake mechanism to provide braking force to the rear wheels through the foot brake cable.

[0006] Furthermore, the disc brake mechanism includes a linkage rod, a disc brake oil pump, and a disc brake caliper; The foot brake is connected to the linkage rod, which is connected to the disc brake pump. The disc brake caliper is located on the front wheel and is connected to the disc brake pump via a disc brake oil pipe. The linkage rod can drive the disc brake pump to deliver oil to the disc brake caliper.

[0007] Furthermore, the foot brake includes a pedal and a foot brake bend, with the pedal located at one end of the foot brake bend and the other end of the foot brake bend connected to the linkage rod.

[0008] Furthermore, a transmission rod is provided between the foot brake bend and the connecting rod.

[0009] Furthermore, the linkage braking structure also includes a handbrake, which is connected to the disc brake pump via a brake cable 205. The handbrake can drive the disc brake pump to deliver oil to the disc brake caliper.

[0010] Furthermore, the drum brake mechanism includes a brake linkage and a drum brake assembly; One end of the brake linkage is connected to the foot brake cable, and the other end is connected to the drum brake assembly, which is connected to the rear wheel.

[0011] Furthermore, a brake lever is provided between the brake linkage and the drum brake assembly.

[0012] Furthermore, the drum brake assembly includes a brake drum and brake shoes. The brake drum is mounted on the rear wheel and rotates synchronously with the rear wheel. The brake shoes are connected to the end of the brake lever opposite to the brake linkage.

[0013] Furthermore, the foot brake cable is equipped with a pull wire, one end of which is connected to the foot brake bend and the other end is connected to the brake linkage.

[0014] This utility model also provides a tricycle, including the above-mentioned linkage braking structure.

[0015] The beneficial effects of this utility model are: This utility model provides a linkage braking structure for tricycles, including a foot brake, a foot brake cable, a disc brake mechanism, and a drum brake mechanism. The foot brake drives the disc brake mechanism to provide braking force to the front wheel, while the foot brake cable drives the drum brake mechanism to provide braking force to the rear wheel. The disc brake mechanism provides strong braking force to the front wheel through the disc brake, thereby effectively shortening the braking distance, increasing the braking effect, and ultimately improving the safety performance during braking, making it easier to cope with various road conditions.

[0016] The tricycle provided by this utility model includes the aforementioned linkage braking structure. It brakes the front wheel with a disc brake and the rear wheel with a drum brake. The front wheel uses a disc brake to obtain strong braking force, which can effectively cooperate with the rear wheel drum brake to improve the overall braking effect and shorten the braking distance. This allows the tricycle to effectively adapt to various road conditions and improve the safety of emergency braking. Attached Figure Description

[0023] Example 1 like Figure 1 As shown, this utility model provides a linkage braking structure for a tricycle, including a foot brake 100, a foot brake cable 101, a disc brake mechanism, and a drum brake mechanism. The foot brake 100 is connected to the disc brake mechanism, which is connected to the front wheel of the tricycle. The foot brake 100 can drive the disc brake mechanism to provide braking force to the front wheel. The foot brake 100 is also connected to the foot brake cable 101, which is connected to the drum brake mechanism. The drum brake mechanism is connected to the two rear wheels of the tricycle respectively. The foot brake 100 can drive the drum brake mechanism to provide braking force to the rear wheels through the foot brake cable 101.

[0024] In this embodiment, the linkage braking structure includes a foot brake 100, a foot brake cable 101, a disc brake mechanism, and a drum brake mechanism. The foot brake 100 drives the disc brake mechanism to provide braking force to the front wheels, while the foot brake cable 101 drives the drum brake mechanism to provide braking force to the rear wheels. The disc brake mechanism provides strong braking force to the front wheels through the disc brake, thereby effectively shortening the braking distance, increasing the braking effect, and ultimately improving the safety performance during braking, making it easier to cope with various road conditions.

[0025] According to one embodiment provided by this utility model, such as Figure 1 As shown, the disc brake braking mechanism includes a linkage 200, a disc brake oil pump 201, and a disc brake caliper 202; The foot brake 100 is connected to the linkage 200, which is connected to the disc brake pump 201. The disc brake caliper 202 is located on the front wheel and is connected to the disc brake pump 201 via the disc brake oil pipe 203. The linkage 200 can drive the disc brake pump 201 to deliver oil to the disc brake caliper 202.

[0026] In this embodiment, when the driver needs to brake during driving, they press the foot brake 100. Since the foot brake 100 is connected to the linkage 200, pressing the foot brake 100 will simultaneously rotate the linkage 200. The linkage 200 is connected to the disc brake pump 201. The rotation of the linkage 200 can drive the disc brake pump 201 to output oil, which is then delivered to the disc brake caliper 202 installed on the front wheel through the disc brake oil pipe 203. This allows the oil to transmit braking force to the disc brake caliper 202 through the disc brake oil pipe 203, thereby enabling the disc brake caliper 202 to obtain power under the push of the oil, powerfully pushing the brake pads so that they can fit tightly against the matching disc brake disc installed on the front wheel, braking the front wheel. Since the disc brake has high braking force, it can achieve efficient braking of the front wheel. The rear wheel is then braked synchronously by the drum brake mechanism.

[0027] According to one embodiment provided by this utility model, such as Figure 1 As shown, the foot brake 100 includes a pedal 102 and a foot brake bend 103. The pedal 102 is located at one end of the foot brake bend 103, and the other end of the foot brake bend 103 is connected to the linkage rod 200.

[0028] In this embodiment, the pedal 102 is located at the position where the driver's foot is placed to facilitate braking. At the same time, a foot brake bend 103 is connected to the back of the foot brake 100, and the other end of the foot brake bend 103 is connected to the linkage 200. Thus, when the driver presses the pedal 102, the foot brake bend 103 is moved backward, and the foot brake bend 103 drives the disc brake oil pump 201 to output oil to brake the front wheels.

[0029] Preferably, a top cover is fitted over the pedal 102. The pedal 102 and the top cover are placed into an integrated mold and stamped together. After forming, the top cover is pressed onto the pedal 102. The integrated stamping process can save costs and avoid the manual assembly of disassembled parts, thus preventing the problem of low production efficiency caused by the inconvenience of assembling disassembled parts. It can also effectively reduce labor intensity.

[0030] Of course, the top cover is made of 1mm thick aluminum sheet by stamping, which reduces overall production costs. At the same time, the top cover and pedal 102 are stamped as a single piece, reducing the number of molds and effectively saving costs. Correspondingly, multiple grooves are stamped on the top cover, and these grooves are evenly spaced. The design of these grooves increases friction when the user steps on the pedal 102, ensuring stability and safety during use.

[0031] According to one embodiment provided by this utility model, such as Figure 1 As shown, a transmission rod 204 is also provided between the foot brake bend 103 and the connecting rod 200.

[0032] In this embodiment, to further coordinate with the linkage 200 to drive the disc brake oil pump 201 to output oil, a transmission rod 204 is also provided between the foot brake bend 103 and the linkage 200. Preferably, the foot brake bend 103 and the linkage 200 are parallel to each other or located on the same straight line, and the transmission rod 204 is perpendicular to the linkage 200. That is, a connecting lug is provided on the chassis of the tricycle, and a rotating hole is opened on the connecting lug. The rotating hole can be a round hole or an oblong hole. The two ends of the transmission rod 204 are rotatably mounted. The corresponding rotating hole allows the transmission rod 204 to generate relative displacement or relative rotation relative to the chassis, thereby pulling the connecting rod 200. One end of the foot brake bend 103 is connected to the outer wall of the transmission rod 204, and the outer wall of the transmission rod 204 is connected to the end of the connecting rod 200 at the corresponding position according to actual use needs, thereby realizing the transmission path of the foot brake bend 103, the transmission rod 204 and the connecting rod 200, so that the driver can press the pedal 102 to apply disc brake to the front wheel.

[0033] According to one embodiment provided by this utility model, such as Figure 1 As shown, the linkage braking structure also includes a handbrake 104, which is connected to the disc brake pump 201 via a brake cable 205. The handbrake 104 can drive the disc brake pump 201 to deliver oil to the disc brake caliper 202.

[0034] In this embodiment, to assist the foot brake 100 in applying disc brakes to the front wheels, the handbrake 104 is also connected to the disc brake pump 201 via the brake cable 205. This allows the handbrake 104 to drive the disc brake pump 201 to deliver oil to the disc brake caliper 202 under the action of the brake cable 205, thus providing a certain degree of auxiliary braking function. When emergency braking is not required, or only a small braking force is needed, or only slow braking is required, the handbrake 104 can be used to apply disc brakes to the front wheels. When emergency braking is required, the handbrake 104 assists the foot brake 100 in quickly applying disc brakes to the front wheels. The driver can make judgments based on the actual road conditions and environment and then take corresponding actions, thereby effectively improving the versatility of braking to suit the driving needs of different drivers.

[0035] According to one embodiment provided by this utility model, such as Figure 1 As shown, the drum brake mechanism includes a brake linkage 300 and a drum brake assembly; One end of the brake linkage 300 is connected to the foot brake cable 101, and the other end is connected to the drum brake assembly, which is connected to the rear wheel.

[0036] In this embodiment, when the driver presses the pedal 102 while driving, the brake linkage 300 is driven by the foot brake cable 101, so that the brake linkage 300 can move or rotate relative to the chassis, thereby pulling the drum brake assembly to brake the rear wheels.

[0037] Optionally, a connecting ear is provided on the chassis, and a rotating hole is opened inside the connecting ear. The rotating hole can be a round hole or an oblong hole. The two ends of the brake linkage 300 can be rotatably installed in the corresponding rotating hole, so that the brake linkage 300 can generate relative displacement or relative rotation relative to the chassis inside, thereby pulling the drum brake assembly to brake.

[0038] According to one embodiment provided by this utility model, such as Figure 1 As shown, a brake lever 301 is provided between the brake linkage 300 and the drum brake assembly.

[0039] In this embodiment, in order to ensure the transmission effect between the brake linkage 300 and the drum brake assembly, a brake lever 301 is provided between the brake linkage 300 and the drum brake assembly. That is, a brake lever 301 is provided at each end of the brake linkage 300. When the brake linkage 300 generates relative displacement or relative rotation relative to the chassis during rotation, it can pull the brake levers 301 at both ends, thereby driving the drum brake assembly away from the end of the brake linkage 300 to perform drum brake braking on the rear wheels.

[0040] According to one embodiment of the present invention, the drum brake assembly includes a brake drum and brake shoes. The brake drum is mounted on the rear wheel and rotates synchronously with the rear wheel. The brake shoes are connected to the end of the brake lever 301 that is away from the brake linkage 300.

[0041] In this embodiment, each rear wheel is equipped with a brake drum that can rotate synchronously with the rear wheel. A brake rocker arm and a cam are also provided. The rocker arm is connected to the brake lever 301. The rocker arm can drive the cam to rotate. The cam can drive the shoe blocks to separate and apply drum brake to the rear wheel. A return spring is also provided between the two shoe blocks. When the braking is completed and the foot brake 100 is released, the return spring will drive the two shoe blocks to return to their original positions so that braking can be applied again.

[0042] Among them, the brake rocker arm, cam and shoe are all existing technologies of drum brakes. Those skilled in the art should know their specific structure and principle, so they will not be described in detail.

[0043] According to one embodiment provided by this utility model, such as Figure 1 As shown, the foot brake cable 101 has a pull wire inside, one end of which is connected to the foot brake bend 103, and the other end is connected to the brake linkage 300.

[0044] In this embodiment, in order to ensure the pulling effect of the foot brake cable 101 on the brake linkage 300, a pull wire is provided inside the foot brake cable 101. Preferably, the pull wire is made of iron wire, which can give it good strength, thereby ensuring its pulling effect on the brake linkage 300 and significantly improving its service life.

[0045] Example 2 This utility model also provides a tricycle, including the above-mentioned linkage braking structure.

[0046] In this embodiment, the tricycle includes the aforementioned linkage braking structure, which brakes the front wheel with a disc brake and the rear wheel with a drum brake. The front wheel uses a disc brake to obtain strong braking force, which can effectively cooperate with the rear wheel drum brake to improve the overall braking effect and shorten the braking distance. This allows the tricycle to effectively adapt to various road conditions and improve the safety of emergency braking.

[0047] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
