Description
Technical Field
[0001] The utility model belongs to the technical field of riding equipment and relates to a brake and riding equipment. Background Art
[0002] In today's transportation landscape, bicycles and electric bicycles have become popular choices for short-distance travel due to their convenience, environmental friendliness, and other advantages. Braking systems are crucial components for cycling safety, and hydraulic brakes are widely used due to their excellent braking performance and responsiveness.
[0003] The existing hydraulic brake parking function of bicycles and electric bicycles is generally achieved by limiting the rebound of the brake handle. When the rider needs to park, after operating the brake handle, a specific device is used to limit the rebound of the handle to maintain the braking state. However, because the rebound of the brake handle is limited, the oil circuit inside the hydraulic brake is continuously in a pressurized state. During the parking period of the vehicle, it is very easy to cause the oil circuit to lose pressure due to various factors, such as temperature changes, slight deformation of brake components, and natural aging of seals. Once pressure loss occurs, the brake system can no longer maintain effective parking braking force, and the vehicle may move unexpectedly, leading to accidents such as vehicle collision and tipping, posing a huge threat to the personal safety of the rider and the safety of surrounding parked vehicles and pedestrians. Summary of the Invention
[0004] The utility model aims to solve the problems existing in the prior art and proposes a brake and a riding device, aiming to overcome the defect that the existing hydraulic brake is prone to pressure loss when the vehicle is parked for a long time, which poses a great safety hazard.
[0005] The utility model is achieved in this way:
[0006] A brake comprises a housing, wherein a first brake pad and a second brake pad are provided on the housing, and a hydraulic drive structure for driving the first brake pad is provided on the housing. The invention is characterized in that a wire drive structure for driving the second brake pad is provided on the housing.
[0007] The wire drive structure includes a swing arm, a driving member fixedly connected to the swing arm, and a transmission column arranged between the driving member and the second brake pad. A guide member is provided on the shell to cooperate with the driving member so that the driving member moves axially relative to the driving member when the driving member rotates.
[0008] The guide member and / or the driving member is provided with an inclined wall hole, and a ball is provided in the inclined wall hole. The inclined wall hole has a deeper first position and a shallower second position. When the ball is in the first position, the brake is in an unlocked state. When the ball is in the second position, the brake is in a braking state.
[0009] The shell includes a main shell and a second shell detachably mounted on the main shell. A limiting groove is provided on the guide member, and a limiting portion cooperating with the limiting groove is provided in the second shell.
[0010] The brake has at least two transmission columns, one end portion of the transmission column close to the driving member is in contact with the driving member, and the other end portion is offset from the transmission column.
[0011] A guide groove is defined in the second shell, and a portion of the transmission column and the driving member that is misaligned is embedded in the guide groove.
[0012] A riding device includes a brake handle and a parking handle, wherein the brake handle is connected to the hydraulic drive structure through a fluid path, and is characterized in that the parking handle is connected to the cable drive structure through a wiring harness.
[0013] The utility model has the following beneficial effects: With the powerful and stable hydraulic force, it achieves an efficient and sensitive braking effect, ensuring that the vehicle can slow down and stop in a short time, meeting the frequent braking needs in daily riding. Combined with the cable-driven structure, this dual-drive structure design ensures that even if the hydraulic system loses pressure due to long-term pressure or encounters a sudden hydraulic failure, the cable-driven second brake pad can still firmly lock the wheel and maintain the vehicle's parking state.

DETAILED DESCRIPTION
[0020] The following is a further detailed description of the specific implementation of the present invention in conjunction with the accompanying drawings to make the technical solution of the present invention easier to understand and grasp. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.
[0021] This embodiment provides a riding device, which can be a pedal bicycle or an electric bicycle. The riding device includes a brake handle, a parking handle and a brake. Figure 1-5 As shown, the brake includes a housing 100, on which a first brake pad 210 and a second brake pad 220 are mounted. A hydraulic drive structure 300 is mounted on the housing 100 to drive the first brake pad 210, and a cable drive structure 400 is mounted on the housing 100 to drive the second brake pad 220. The brake handle is connected to the hydraulic drive structure 300 via a hydraulic circuit, and the parking handle is connected to the cable drive structure 400 via a wiring harness. The first brake pad 210 and the second brake pad 220 are arranged in correspondence and can clamp the same brake disc.
[0022] The hydraulic drive structure 300 of this embodiment is used for deceleration and braking during driving, and the cable drive structure 400 is mainly used for parking when stopping. If necessary, the cable drive structure 400 can also be used for deceleration and braking during driving.
[0023] The brake body comprises a housing 100, on which are mounted a first brake pad 210 and a second brake pad 220. A hydraulic drive structure 300 is provided for the first brake pad 210. During normal braking, the hydraulic drive structure 300 plays a leading role. When the rider squeezes the brake handle, the hydraulic system responds quickly, precisely transmitting pressure through the oil circuit to drive the first brake pad 210 into close contact with the brake disc. This powerful and stable hydraulic force achieves efficient and sensitive braking, ensuring the vehicle can be decelerated and stopped in a short time, meeting the frequent braking needs of daily riding.
[0024] What is particularly critical is that a cable-driven structure 400 that drives the second brake pad 220 is added to the housing 100. When parking is required, by pulling the cable connected to it, the second brake pad 220 can be accurately driven to move toward the brake disc, so that it is in close contact with the brake disc and generates additional braking force. This dual-drive structural design can still lock the wheel steadily and maintain the vehicle's parking state even when the hydraulic system loses pressure due to long-term pressure or encounters a sudden hydraulic failure. In this way, the reliability and stability of parking are greatly improved, and vehicle accidents caused by parking failure are effectively avoided. The safety of cyclists when parking is fully guaranteed, making the use of bicycles and electric bicycles more worry-free.
[0025] Furthermore, the wire drive structure 400 includes a swing arm 410, a driving member 420 fixedly connected to the swing arm 410, and a transmission column 430 arranged between the driving member 420 and the second brake pad 220. The housing 100 is provided with a guide member 440 to cooperate with the driving member 420 so that the driving member 420 moves axially relative to the driving member 420 when the driving member 420 rotates.
[0026] The swing arm 410, a direct load-bearing component, is securely connected to a cable at one end. When the rider pulls the cable, the swing arm 410 pivots around a fixed pivot point. This rotation of the swing arm 410 drives the synchronous movement of the driver 420, which is fixed to it. Because the driver 420 is rigidly connected to the swing arm 410, the linkage between them is precise and rapid, ensuring efficient power transmission.
[0027] The guide member 440 cooperates with the driver 420, enabling the driver 420 to move axially relative to itself during rotation. This unique motion cleverly transforms the rotational motion transmitted by the swing arm 410 into a combined rotational and axial motion of the driver 420. The transmission post 430, positioned between the driver 420 and the second brake pad 220, receives the movement of the driver 420 and transmits it to the second brake pad 220, enabling the second brake pad 220 to move toward the brake disc.
[0028] The entire cable-driven structure 400 forms a stable and efficient power transmission link. Whether for daily short-term parking or longer-term parking, it can quickly and reliably execute parking tasks in the event of unexpected hydraulic system failures, effectively ensuring the vehicle is parked securely. This significantly improves the safety of bicycles and e-bikes in various usage scenarios and eliminates the worry of parking failure for riders.
[0029] The hydraulic drive structure 300 generally includes a piston. The brake handle drives the fluid in the fluid circuit to flow and drive the piston, and the piston pushes the first brake pad 210 .
[0030] like Figure 4 、 5 As shown, an inclined wall hole 450 is provided on the guide member 440 and the driving member 420, and a ball 460 is provided in the inclined wall hole 450. The inclined wall hole 450 has a deeper first position and a shallower second position. When the ball 460 is in the first position, the brake is in an unlocked state. When the ball 460 is in the second position, the brake is in a braking state.
[0031] The sloped hole 450 formed in the guide member 440 and the driver 420 has a gradually varying depth, with a deeper first position and a shallower second position. When the ball bearing 460 is in the deeper first position of the sloped hole 450, the brake is unlocked. This means that during normal riding, the ball bearing 460 poses no additional obstruction to the movement of the driver 420 or the entire brake system. The wheels can rotate freely, the vehicle travels smoothly, and the rider experiences no unusual resistance from the parking mechanism, ensuring a comfortable and smooth riding experience.
[0032] When parking is required, the pull cord is pulled to move the driver 420, causing the ball 460 in the inclined wall hole 450 to roll along the inclined wall to a shallower second position. When the ball 460 is in the second position, the inclined wall hole 450 is shallower and the guide member 440 is stationary, so the ball 460 pushes the driver 420 to move.
[0033] In other optional embodiments, the guide member 440 and the driving member 420 may also be in contact with each other through oblique walls to achieve conversion of rotation into axial movement.
[0034] like Figure 1 、 2 As shown, the housing 100 includes a main housing 110 and a second housing 120 that is removably mounted on the main housing 110. The guide member 440 is provided with a retaining groove 441, and the second housing 120 is provided with a retaining portion 122 that cooperates with the retaining groove 441. When the brake requires repair, maintenance, or component replacement after extended use, the user can simply remove the second housing 120 to quickly access the internal guide member 440 and related components of the cable drive structure 400, eliminating the need for complex disassembly of the entire brake, significantly reducing maintenance costs and difficulty. The retaining groove 441 and the retaining portion 122 prevent the guide member 440 from rotating relative to the second housing 120.
[0035] like Figure 2As shown, the brake has two transmission columns 430. One end of the transmission column 430 near the driving member 420 abuts the driving member 420, while the other end is offset from the transmission column 430. Compared to a single transmission column 430 structure, this multi-column design significantly improves the stability and balance of power transmission. The housing 100 has a guide hole, and the transmission column 430 is installed in the guide hole, allowing stable movement. In other optional embodiments, the transmission column 430 can also be one or more than two.
[0036] like Figure 3 As shown, the second housing 120 has a guide groove 121 therein, into which the portion of the transmission column 430 that is misaligned with the driver 420 is inserted. This effectively prevents the transmission column 430 from deviating from its intended trajectory during force transmission, preventing power transmission deviations caused by misalignment or shaking. This allows the parking force to be transmitted to the second brake pad 220 along the most optimized path, ensuring accurate and efficient power transmission.
