Description

Technical Field

[0002] With the development of intelligent technology in two-wheeled vehicles (such as bicycles and motorcycles), people are increasingly concerned about safety, and the installation of parking brakes on two-wheeled vehicles is becoming increasingly common. Traditional parking brake systems mostly use a separate brake system. When the rear brake handle is squeezed, only the rear brake generates braking force, and a locking mechanism locks the rear brake handle to achieve parking. With the popularization of combined braking, squeezing the rear combined brake handle while using a two-wheeled vehicle generates braking force on both the front and rear brakes. Because the front brake uses a disc brake, hydraulic pressure is transmitted through a rubber hose to brake the front wheel, and the rear brake uses a drum brake, braking the rear wheel through brake pads, the rubber hose of the front disc brake can fail during prolonged parking, posing a safety hazard. Summary of the Invention

[0032] In the field of two-wheeled vehicle technology, with the popularization of combined braking, when the rear combined brake handle is squeezed during use, both the front and rear brakes will generate braking force. The front brake can be a drum brake or a disc brake, and the rear brake can be a drum brake. However, the inventor found that when the front brake is a disc brake and the rear brake is a drum brake, there are disadvantages in using a parking method that uses a combined brake handle to lock the front and rear brakes separately, because the front brake transmits the brake hydraulic pressure through a rubber tube. If the parking method of locking the combined brake handle is still used, the rubber tube of the front brake will continue to expand due to the hydraulic pressure when parking. In extreme cases, long-term parking of the two-wheeled vehicle may cause the rubber tube of the front brake to fail, posing a safety hazard.

[0033] Based on this, it is necessary to propose a parking brake device, a brake system and a two-wheeled vehicle to improve the problem of failure of the front brake rubber tube during long-term parking, so as to improve the safety of the two-wheeled vehicle.

[0034] See Figure 1 and Figure 2 The parking brake device 2 provided in one embodiment of the present application includes a fixed bracket 21, a brake mechanism 22 and a parking member 23. The fixed bracket 21 is used to be mounted on the handlebar 1. The brake mechanism 22 includes a brake member 221, a front brake output member 222 and a rear brake output member 223. The brake member 221 is rotatably connected to the fixed bracket 21. The front brake output member 222 and the rear brake output member 223 respectively pass through the fixed bracket 21 and are connected to the brake member 221. The parking member 23 is provided on the fixed bracket 21 and is close to the rear brake output member 223. The parking member 23 is provided with a first stop portion 231.

[0035] During the rotation of the brake member 221, the parking brake device 2 can be switched between a locked state and an unlocked state under the action of the first stop portion 231. In the locked state, the brake member 221 is located in the preset parking position, a first gap is formed between the brake member 221 and the front brake output member 222, and a second gap is formed between the brake member 221 and the rear brake output member 223. The first stop portion 231 is located within the second gap and abuts between the brake member 221 and the fixed bracket 21. The dimension of the first gap along the axis of the front brake output member 222 is smaller than the dimension of the second gap along the axis of the rear brake output member 223.

[0036] It should be noted that the fixing bracket 21 is detachably mounted to the handlebar 1 via bolts. The first retaining portion 231 can be rectangular, spherical, or in any other shape. The front brake output member 222 includes a front brake control line and a front control output terminal. The rear brake output member 223 includes a rear brake control line and a rear brake output terminal.

[0037] Specifically, when braking the two-wheeled vehicle, the brake member 221 is pinched by hand to generate braking force to the front brake output member 222 and the rear brake output member 223, so that the front wheel disc brake and the rear wheel drum brake are braked at the same time to slow down the two-wheeled vehicle. When parking for a long time, the first stopper 231 is pressed down and the brake member 221 is returned or rotated to the preset parking position. The first stopper 231 is located in the second interval and the first stopper 231 is in contact between the brake member 221 and the fixed bracket 21, so that the two-wheeled vehicle is in a locked state, that is, a parking state.

[0038] It can be understood that the dimension of the first interval along the axial direction of the front brake output member 222 is smaller than the dimension of the second interval along the axial direction of the rear brake output member 223, that is, the spacing distance between the brake member 221 and the front brake output member 222 is smaller than the spacing distance between the brake member 221 and the rear brake output member 223. Under the resistance of the first resisting portion 231, at this time, the braking force of the front brake output member 222 is released as much as possible, and only the braking force of the rear brake output member 223 is maintained, so that the two-wheeled vehicle remains in a parking state, and the hydraulic pressure of the rubber tube of the front brake disc is reduced, thereby improving the problem of failure of the front brake rubber tube during long-term parking, thereby improving the safety of the two-wheeled vehicle.

[0039] It should be noted that the first gap specifically refers to the gap between the position where the front brake output member 222 just passes through the fixed bracket 21 and the brake member 221. The second gap specifically refers to the gap between the position where the rear brake output member 223 just passes through the fixed bracket 21 and the brake member 221. The preset parking position means that the brake member 221 is in a position that meets the parking requirements, that is, the second gap can accommodate the first stop portion 231, so that the braking force of the rear brake output member 223 is maintained and the braking force of the front brake output member 222 is close to zero.

[0040] The present application is provided with a parking member 23, and the parking member 23 is provided with a first resisting portion 231. When using combined braking, the brake member 221 is pinched to make the brake member 221 located in a preset parking position. The dimension of the first interval along the axial direction of the front brake output member 222 is smaller than the dimension of the second interval along the axial direction of the rear brake output member 223. Under the resisting action of the first resisting portion 231, the braking force of the front brake output member 222 is released as much as possible, and only the braking force of the rear brake output member 223 is maintained, so that the two-wheeled vehicle remains in a parked state, and the hydraulic pressure of the rubber tube of the front brake disc is reduced, and the rubber tube will not be expanded by the hydraulic pressure all the time, thereby improving the problem of failure of the front brake rubber tube during long-term parking and improving the safety of the two-wheeled vehicle.

[0041] In this example, please continue to refer to Figure 1 In the unlocked state, the brake member 221 is located at the initial position, the brake member 221 abuts against the fixing bracket 21 , and the first blocking portion 231 is located on one side of the brake member 221 .

[0042] It should be noted that the initial position refers to the position where the brake member 221 has not yet begun to rotate. When the parking brake device 2 is switched from the locked state to the unlocked state, the brake member 221 can be rotated and the first stop portion 231 of the parking member 23 can be pulled up, so that the brake member 221 directly contacts the fixed bracket 21. The first stop portion 231 is located on one side of the brake member 221, that is, the first stop portion 231 is located directly above or diagonally above the brake member 221.

[0043] In some embodiments, the front brake output 222 is closer to the handlebar 1 than the rear brake output 223 .

[0044] Specifically, when the front brake output member 222 and the rear brake output member 223 are respectively fixed to the fixed bracket 21, the front brake output member 222 is closer to the handlebar 1 than the rear brake output member 223, so that during the rotation of the brake member 221, the first interval along the axial direction of the front brake output member 222 is smaller than the second interval along the axial direction of the rear brake output member 223, that is, the interval distance between the brake member 221 and the front brake output member 222 is smaller than the interval distance between the brake member 221 and the rear brake output member 223, and under the resistance of the first resisting portion 231, the braking force of the front brake output member 222 is released as much as possible, and only the braking force of the rear brake output member 223 is maintained, so that the two-wheeled vehicle remains in a parked state, and the hydraulic pressure of the rubber tube of the front brake disc is reduced, thereby improving the problem of failure of the front brake rubber tube during long-term parking, thereby improving the safety of the two-wheeled vehicle.

[0045] In some embodiments, please refer to Figure 1 and Figure 2Braking member 221 includes a brake portion 2211 and a balancing portion 2212 connected to each other. Braking portion 2211 is rotatably connected to fixed bracket 21. One end of balancing portion 2212 is connected to front brake output member 222, and the other end is connected to rear brake output member 223. Balancing portion 2212 is used to distribute the braking force output by braking member 2211 to front brake output member 222 and rear brake output member 223.

[0046] In some embodiments, in the locked state, the balancing portion 2212 is located at a preset parking position, a first gap is formed between the balancing portion 2212 and the front brake output member 222, a second gap is formed between the balancing portion 2212 and the rear brake output member 223, the first blocking portion 231 is located in the second gap, and the first blocking portion 231 abuts between the balancing portion 2212 and the fixed bracket 21.

[0047] It should be noted that the braking portion 2211 specifically refers to the brake handle. One end of the balancing portion 2212 is connected to the front brake output member 222, and the other end is connected to the rear brake output member 223. The balancing portion 2212 is used to quantitatively distribute the braking force output by the braking portion 2211 to the front brake output member 222 and the rear brake output member 223 in varying proportions. This distribution ratio can be determined based on the lever ratio of the front and rear brake circuits.

[0048] Specifically, during the rotation of the braking part 2211, the balancing part 2212 is driven to rotate and different braking forces are distributed to the front brake output member 222 and the rear brake output member 223, so that the front wheel disc brake and the rear wheel drum brake are braked at the same time to slow down the two-wheeled vehicle. When you want to park for a long time, press the first resisting part 231, and return the braking part 2211 or rotate it so that the balancing part 2212 is located in the preset parking position, a first gap is formed between the balancing part 2212 and the front brake output member 222, and a second gap is formed between the balancing part 2212 and the rear brake output member 223, the first resisting part 231 is located in the second gap, and the first resisting part 231 is in contact between the balancing part 2212 and the fixed bracket 21, so that the two-wheeled vehicle is in a locked state, that is, a parking state.

[0049] It can be understood that when the parking brake device 2 is switched from a locked state to an unlocked state, the braking portion 2211 can be rotated and the first stop portion 231 of the parking member 23 can be pulled up so that the balancing portion 2212 is directly abutted against the fixed bracket 21. The first stop portion 231 is located on one side of the balancing portion 2212, that is, directly above or diagonally above the balancing portion 2212.

[0050] In some embodiments, please refer to Figure 1 and Figure 2The parking member 23 includes a base 232 and a parking portion 233. The parking portion 233 and the base 232 are rotatably connected. The base 232 is provided on the fixed bracket 21 and is close to the rear brake output member 223. The first blocking portion 231 is provided on the parking portion 233. The parking portion 233 is configured to enable the first blocking portion 231 to be located at or away from the second interval position so that the parking brake device 2 can be switched between a locked state and an unlocked state.

[0051] Specifically, the parking portion 233 specifically refers to the parking handle. When the brake portion 2211 is pinched and rotated, different braking forces are distributed to the front brake output member 222 and the rear brake output member 223 through the balancing portion 2212, thereby causing the front wheel disc brake and the rear wheel drum brake to brake simultaneously. By rotating the parking portion 233 counterclockwise, the first stop portion 231 is located between the balancing portion 2212 and the fixed bracket 21, and the brake portion 2211 is released, the balancing portion 2212 returns to the preset parking position, the first stop portion 231 is located in the second gap, and the first stop portion 231 abuts between the balancing portion 2212 and the fixed bracket 21, so that the two-wheeled vehicle is in a locked state, that is, a parking state.

[0052] Furthermore, when the parking brake device 2 is switched from the locked state to the unlocked state, the braking portion 2211 is rotated and the parking portion 233 is rotated clockwise to make the first resisting portion 231 leave the position between the balancing portion 2212 and the fixed bracket 21, and the braking portion 2211 is released, and the balancing portion 2212 returns to its initial position. The balancing portion 2212 directly abuts against the fixed bracket 21, and the first resisting portion 231 is located on one side of the balancing portion 2212, that is, the first resisting portion 231 is located directly above or obliquely above the balancing portion 2212.

[0053] In some embodiments, the parking portion 233 is detachably connected to the base 232. Specifically, the parking portion 233 and the base 232 are fixed by bolts, which is convenient for disassembly, replacement or installation.

[0054] In some embodiments, the parking portion 233, the first stop portion 231, and the second stop portion 234 are an integrated structure. The integrated structure refers to a structure that can be manufactured through an integrated molding process and can be made of aluminum alloy, with high plasticity in appearance.

[0055] In some embodiments, the parking member 23 further includes a first elastic member 235, one end of the first elastic member 235 being connected to the base 232 and the other end being connected to the parking portion 233. In the unlocked state, the first resisting portion 231 can be positioned outside the second gap due to the elastic force of the first elastic member 235.

[0056] Specifically, the first elastic member 235 can be a return torsion spring, one end of which is connected to the base 232 and the other end is connected to the parking portion 233. When the parking brake device 2 is switched from the locked state to the unlocked state, the braking portion 2211 is rotated to increase the spacing between the balancing portion 2212 and the rear brake output member 223. Under the elastic force of the return torsion spring, the first stop portion 231 can automatically spring up and leave the second spacing position, thereby facilitating operation and enabling single-handed unlocking.

[0057] In some embodiments, please refer to Figure 1 and Figure 2 The parking member 23 further includes a second resisting portion 234, which is provided at the parking portion 233 and close to the base 232. The second resisting portion 234 is used to abut against the base 232 when in the unlocked state, so that the parking portion 233 remains stationary relative to the base 232.

[0058] Specifically, the second resisting portion 234 can be in a rectangular block, spherical or other shapes. When in the unlocked state, the second resisting portion 234 abuts against the base 232, so that the parking portion 233 remains stationary relative to the base 232, preventing the parking portion 233 from moving.

[0059] In some embodiments, the brake mechanism 22 further includes a second elastic member (not shown) that is mounted to the rear wheel. One end of the second elastic member is connected to the rear wheel drum brake, and the other end is connected to the rear wheel mounting bracket. The rear brake output member 223 is connected to the drum brake.

[0060] It should be noted that the second elastic member can be a cable return spring. The control line of the rear brake output member 223 is connected to the drum brake. Therefore, while pinching the brake portion 2211 and rotating it, the first stopper 231 is pressed, and then the brake portion 2211 is released. Under the elastic action of the cable return spring, the control line of the rear brake output member 223 pulls the balancing portion 2212 back to the preset parking position, causing the first stopper 231 to abut between the balancing portion 2212 and the fixed bracket 21, thereby quickly locking the two-wheeled vehicle. In addition, to unlock the two-wheeled vehicle, pinching the brake portion 2211 and rotating it, and returning the first stopper 231 to its original position, and then releasing the brake portion 2211, the control line of the rear brake output member 223 pulls the balancing portion 2212 back to its initial position under the elastic action of the cable return spring, thereby quickly unlocking the two-wheeled vehicle.

[0061] The braking system provided by one embodiment of the present application includes the parking brake device 2 as described above, and the braking system also includes a disc brake controller and a drum brake controller. The disc brake controller is used to be installed on the front wheel, and the drum brake controller is used to be installed on the rear wheel. The disc brake controller is connected to the front brake output member 222, and the drum brake controller is connected to the rear brake output member 223. Specifically, the disc brake controller is connected to the control line of the front brake output member 222, and the drum brake controller is connected to the control line of the rear brake output member 223. When combined braking is used for parking, the front braking force is released as much as possible, and only the rear braking force is maintained, thereby improving the problem of failure of the rubber tube of the front brake during long-term parking.

[0062] A two-wheeled vehicle provided in one embodiment of the present application includes the brake system described above. A parking brake device 2 is mounted on a handlebar 1. By operating the parking brake device 2, combined front and rear wheel braking is achieved, allowing the vehicle to remain parked. During parking, the front braking force is minimized, maintaining only the rear braking force. This mitigates the issue of front brake rubber hose failure during prolonged parking, thereby improving the safety of the vehicle.

[0063] The present application is provided with a parking member 23, and the parking member 23 is provided with a first resisting portion 231. When using combined braking, the brake member 221 is pinched to make the brake member 221 located in a preset parking position. The dimension of the first interval along the axial direction of the front brake output member 222 is smaller than the dimension of the second interval along the axial direction of the rear brake output member 223. Under the resisting action of the first resisting portion 231, the braking force of the front brake output member 222 is released as much as possible, and only the braking force of the rear brake output member 223 is maintained, so that the two-wheeled vehicle remains in a parked state, and the hydraulic pressure of the rubber tube of the front brake disc is reduced, and the rubber tube will not be expanded by the hydraulic pressure all the time, thereby improving the problem of failure of the front brake rubber tube during long-term parking and improving the safety of the two-wheeled vehicle.

[0064] The technical features of the above-mentioned embodiments can be combined arbitrarily. In order to make the description concise, not all possible combinations of the technical features in the above-mentioned embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0065] The above-described embodiments merely represent several implementation methods of the present application. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that a person of ordinary skill in the art may make various modifications and improvements without departing from the spirit of the present application, and these modifications and improvements fall within the scope of protection of the present application. Therefore, the scope of protection of the present patent application shall be determined by the appended claims.
