[0001] The embodiments of the present application belong to the field of braking devices, and more specifically, to a braking device and a vehicle having the braking device. Background Art

[0002] Common two-wheeled vehicles include motorcycles, electric bicycles and bicycles. As we all know, for driving safety, all types of vehicles are equipped with braking systems.

[0003] The braking system, commonly known as the "brake" system, refers to a system device that can stop or slow down a running locomotive, vehicle, other transportation vehicle or machinery. Currently, common braking devices can be roughly divided into disc brakes and drum brakes. Disc brakes are also called disc brakes. Existing vehicles almost all have front and rear brake devices that work independently without interfering with each other, that is, the front brake device is used to provide braking force for the front wheels, and the rear brake device is used to provide braking force for the rear wheels.

[0004] At present, when the rear brake pedal of a straddle bike, underbone bike or scooter is operated alone, it can only provide braking force for the rear wheel brake independently; unless the user holds the front brake handle tightly with his hand while stepping on the rear brake pedal, the front and rear wheels can be braked at the same time. When encountering an emergency, most users of the existing brake device will step on the rear brake pedal first and easily forget to hold the front brake handle, especially those with poor psychological quality, which may easily lead to insufficient braking force of the vehicle and cause danger.

[0005] Therefore, in order to improve the braking efficiency of the vehicle, the existing braking device needs to be improved urgently. Summary of the invention

[0010] As a further improvement of the present application, the hydraulic mechanism includes a cylinder and a piston rod, one end of the cylinder is connected to the front brake, one end of the piston rod extends into the interior of the cylinder, a first elastic member is sleeved on the outside of the piston rod, one end of the first elastic member abuts against the cylinder, and the other end is connected to the outer wall of the piston rod, and the end of the piston rod away from the cylinder is hinged to the second rotating block.

[0011] As a further improvement of the present application, a refueling pipe is provided on the oil cylinder, one end of the refueling pipe is connected to the interior of the oil cylinder, and the other end of the refueling pipe is provided with a refueling port.

[0013] As a further improvement of the present application, the pedal resetting mechanism is a second elastic member, the second elastic member is connected to the rear brake rod, and the elastic force of the second elastic member is smaller than the elastic force of the first elastic member.

[0014] As a further improvement of the present application, it also includes a holding mechanism, and the holding mechanism is connected to the front brake.

[0016] With the technical solution of this application, when the user applies driving force to the brake pedal, the brake pedal drives the linkage mechanism to move, and the linkage mechanism drives the rear brake to work, providing braking force to the rear wheel; at the same time, the linkage mechanism transmits the driving force to the hydraulic mechanism, drives the hydraulic mechanism to work, and the hydraulic mechanism drives the front brake to work, providing braking force to the front wheel. This enables the front and rear brakes to achieve joint braking, improves braking efficiency, and ensures riding safety.

[0017] On the other hand, a first elastic member is provided in the hydraulic mechanism, and the elastic force of the first elastic member is greater than the elastic force of the second elastic member, so that when the user steps on the pedal, the hydraulic mechanism of the rear brake starts working first, that is, the rear brake is first provided with braking force by the front brake, which can prevent the front wheel from locking prematurely when the vehicle brakes, thereby further improving the safety of riding.

[0029] In order to enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only embodiments of a part of the present application, not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in the field without creative work should fall within the scope of protection of the present application.

[0030] Example 1

[0031] like Figure 1-4 As shown, a braking device includes a front brake 1, a holding mechanism 2, a rear brake 3, a brake pedal 4, a linkage mechanism and a hydraulic mechanism. Among them, the front brake 1 is a hydraulic butterfly brake, and the front brake 1 is used to provide braking force for the front wheel 17 of the vehicle; the rear brake 3 is a drum brake, and the rear brake 3 is used to provide braking force for the rear wheel 18 of the vehicle. The holding mechanism 2 is fixedly connected to the front brake 1 through an oil pipe, and the holding mechanism 2 is used to provide braking force for the front wheel 17 of the vehicle alone. The linkage mechanism can drive the rear brake 3 to work, the hydraulic mechanism is used to drive the front brake 1 to work, and the brake pedal 4 can drive the linkage mechanism to move. The linkage mechanism is connected to the brake pedal 4, the rear brake 3 and the hydraulic mechanism respectively, and the end of the hydraulic mechanism away from the linkage mechanism is connected to the front brake 1.

[0032] When the user steps on the brake pedal 4 and outputs the driving force to the brake pedal 4, the brake pedal 4 rotates to transmit the driving force to the linkage mechanism, which transmits the driving force to the rear brake 3, drives the rear brake 3 to work, and provides braking force for the rear wheel 18; in addition, when the driving force is greater than the holding force of the night-pressing mechanism, the linkage mechanism can drive the hydraulic mechanism to work, and the hydraulic mechanism drives the front brake 1 to work, providing braking force for the front wheel 17. Thus, the front and rear brakes are combined for braking, the braking efficiency is improved, and the riding safety of the user is guaranteed.

[0033] The brake pedal 4 includes a driving block 41, a rotating shaft 42 and a connecting block 43. The rotating shaft 42 is fixedly connected to one end of the connecting block 43 and one end of the driving block 41 respectively, and the other end of the connecting block 43 is rotatably limitedly connected to the linkage mechanism. In this embodiment, the driving block 41, the rotating shaft 42 and the connecting block 43 are integrally formed structures of metal materials; of course, in other embodiments, the driving block 41, the rotating shaft 42 and the connecting block 43 can also be independent components, which are fixedly connected together by bolts or other structures.

[0034] When the brake device is installed on a vehicle, the rotating shaft 42 is fixed on the vehicle frame and can rotate in place when working; the driving block 41 serves as the force point when the brake device is working, receives the user's braking driving force, and transmits the driving force to the connecting block 43 through the lever principle; the connecting block 43 is used to transmit the driving force to the linkage mechanism. When working, the user applies the braking driving force to the driving block 41, driving the rotating shaft 42 to rotate, thereby driving the connecting block 43 to rotate; the rotation of the connecting block 43 drives the linkage mechanism to move, thereby transmitting the driving force to the linkage mechanism.

[0035] In this embodiment, the angle between the orientation of the driving block 41 and the orientation of the connecting block 43 is less than 180°, that is, the driving block 41 and the connecting block 43 are not on the same straight line, which can ensure that the driving force of the brake can be more efficiently transmitted from the driving block 41 to the connecting block 43. Obviously, in other embodiments, the orientation of the driving block 41 and the orientation of the connecting block 43 can also be on the same straight line, as long as it can ensure that the driving block 41 can drive the connecting block 43 to rotate with the rotating shaft 41 as the central axis.

[0036] The linkage mechanism includes a first rotating member 5 and a second rotating member 6. One end of the first rotating member 5 is hinged to the side of the connecting block 43 away from the rotating shaft 42 through a pin 7, and the other end is fixedly connected to the rear brake 3 through a rear brake rod 8. The end of the rear brake rod 8 away from the rear brake 3 is hinged to the first rotating member 5. A clamping block 51 is provided on one side of the first rotating member 5 close to the connecting block 43. The clamping block 51 is clamped and limitedly connected to one end of the second rotating member 6. The other end of the second rotating member 6 is fixedly connected to the hydraulic mechanism.

[0037] During operation, the braking driving force is transmitted to the first rotating member 5 through the connecting block 43. Since the first rotating member 5 and the rear brake 3 are in a rigid connection, the braking driving force can be directly transmitted to the rear brake 3 to drive the rear brake 3 to work, thereby braking the rear wheel 18 of the vehicle; at the same time, a part of the driving force is transmitted to the second rotating member 6 to drive the hydraulic mechanism to work.

[0038] The second rotating member 6 includes a first rotating block 61, a second rotating block 62 and a central rotating shaft 63. The central rotating shaft 63 is fixedly connected to one end of the first rotating block 61 and one end of the second rotating block 62 respectively, and the first rotating block 61 and the second rotating block 62 can rotate synchronously with the central rotating shaft 63 as a base point. The end of the first rotating block 61 away from the central rotating shaft 63 is clamped with the clamping block 51, and the end of the second rotating block 62 away from the central rotating shaft 63 is fixedly connected to the hydraulic mechanism.

[0039] When working, when the first rotating member 5 transmits the driving force to the second rotating member 6 through the clamping block 51, the first rotating block 61 is driven to rotate, and the first rotating block 61 drives the central rotating shaft 63 to rotate, thereby driving the second rotating block 62 to rotate synchronously, and the second rotating block 62 transmits the driving force to the hydraulic mechanism. When the driving force is greater than the holding force of the hydraulic mechanism, the hydraulic mechanism is driven to work, and the hydraulic mechanism drives the front brake 1 to work, thereby braking the front wheels 17 of the vehicle.

[0040] In this embodiment, the central rotating shaft 63 is sleeved on the outer side of the rotating shaft 42, and the central rotating shaft 63 is movably limitedly connected with the rotating shaft 42. That is, the brake pedal 4 and the second rotating member 6 rotate on the same central axis, making the entire brake device structure more compact. In other embodiments, the central rotating shaft 63 and the rotating shaft 42 may not rotate on the same central axis, that is, the brake pedal 4 and the second rotating member 6 are staggered and distributed.

[0041] In this embodiment, the central shaft 63, the first rotating block 61 and the second rotating block 62 are an integrally formed structure of metal materials. In other embodiments, the central shaft 63, the first rotating block 61 and the second rotating block 62 may also be independent components fixed together by bolts or other structures.

[0042] In this embodiment, the overall structure of the second rotating member 6 is similar to a "windmill" shape, and the first rotating block 61 and the second rotating block 62 are similar to two "fan blades" and can rotate around the central shaft 63. Moreover, the angle between the orientation of the first rotating block 61 and the orientation of the second rotating block 62 is less than 180°, thereby ensuring the compactness of the structure of the braking device and improving the transmission efficiency of the braking force. Obviously, in other embodiments, the first rotating block 61 and the second rotating block 62 can also be in any other orientation.

[0043] The hydraulic mechanism includes a cylinder 9 and a piston rod 10. Hydraulic oil is provided in the cylinder 9. One end of the cylinder 9 is fixedly connected to the front brake 1 through an oil pipe. A sealing cover 11 is provided at the other end of the cylinder 9. One end of the piston rod 10 passes through the sealing cover 11 and extends into the cylinder 9. A first elastic member is sleeved on the outer side of the piston rod 10. In this embodiment, the first elastic member is a first elastic member 12. In other embodiments, the first elastic member can also be other mechanical structures with the same function. One end of the first elastic member 12 abuts against the sealing cover 11, and the other end is fixedly connected to the outer wall of the piston rod 10. The end of the piston rod 10 away from the cylinder 9 is hinged and fixed to the second rotating block 62.

[0044] During operation, when the driving force transmitted to the piston rod 10 by the second rotating block 62 is greater than the holding force of the first elastic member 12, the second rotating block 62 drives the piston rod 10 to squeeze the first elastic member 12, and the extension spring 12 is compressed. At the same time, the end of the piston rod 10 moves into the oil cylinder 9, squeezing the hydraulic oil inside the oil cylinder 9 to generate hydraulic pressure. The oil cylinder 9 transmits the hydraulic pressure to the front brake 1 through the oil pipe, thereby driving the front brake 1 to work and brake the front wheel 17 of the vehicle. When the braking driving force disappears, the first elastic member 12 quickly resets, thereby stopping the front brake 1 from generating braking force.

[0045] Insufficient hydraulic oil in the oil cylinder 9 will directly lead to insufficient braking force of the front brake 1, affecting riding safety. In order to ensure that the hydraulic oil in the oil cylinder 9 can generate sufficient hydraulic pressure, a refueling pipe 13 is provided on the oil cylinder 9, one end of which is connected to the inside of the oil cylinder 9, and a refueling port 14 is provided at the other end of the refueling pipe 13. When the hydraulic oil in the oil cylinder 9 is insufficient, hydraulic oil can be added to the oil cylinder 9 from the refueling port 14 to ensure that there is always sufficient hydraulic oil in the oil cylinder 9.

[0046] The linkage mechanism is provided with a pedal reset device. In the present embodiment, the pedal reset device is a second elastic member 15; in other embodiments, the pedal reset device may also be other elastic members with the same function. One end of the second elastic member 15 is fixedly connected to the rear brake rod 8, and the other end is fixedly connected to the frame of the vehicle. When the user steps on the brake pedal 4 and outputs a driving force to the brake pedal 4, and the driving force is greater than the elastic force of the second elastic member 15, the brake pedal 4 transmits the driving force to the linkage mechanism, thereby driving the rear brake rod 8 to move, driving the rear brake 3 to work, and stretching the second elastic member 15 at the same time. When the braking is completed, the user releases the brake pedal 4, and under the elastic force of the second elastic member 15, the rear brake rod 8 is reset, pulling the linkage mechanism to move, and the linkage mechanism drives the brake pedal 4 to reset quickly.

[0047] In order to prevent the front wheels 17 of the vehicle from locking prematurely during operation, the elastic force of the second elastic member 15 is smaller than the elastic force of the first elastic member 12 .

[0048] Working principle:

[0049] like Figure 4-6 As shown, before braking, no force is applied to the driving block 41; at the initial stage of braking, when the force of the user stepping on the driving block 41 is less than the elastic force of the first elastic member 12 and greater than the elastic force of the second elastic member 15, the rear brake rod 8 moves to control the rear brake 3 to work and provide braking force for the rear wheel 18 of the vehicle; until the force of the user stepping on the driving block 41 is greater than the elastic force of the first elastic member 12, the hydraulic mechanism starts to work, controls the front brake 1 to work, and provides braking force for the front wheel 17 of the vehicle. This allows the braking device to meet the use requirements of front and rear wheel combined braking, and during each braking process, the rear brake 3 starts to work before the front brake 1, which can prevent the front wheel 17 from locking in advance and ensure riding safety.

[0050] In the embodiment of the present application, the holding mechanism 2 is a front brake grip, the first elastic member 12 is a delay spring, and the second elastic member 15 is a delay spring.

[0051] Example 2

[0052] like Figure 7 As shown, a vehicle including the above-mentioned braking device also includes a frame 16, a front wheel 17 and a rear wheel 18, the front wheel 17 and the rear wheel 18 are respectively fixed on the frame 16, the front brake 1 is installed on the front wheel 17, and the rear brake 3 is installed on the rear wheel 18. The oil cylinder 9 is fixedly connected to the frame 16, and the rotating shaft 42 in the brake pedal 4 and the central rotating shaft 63 on the second rotating member 6 are respectively fixed on the frame 16, so that the brake pedal 4 and the second rotating member 6 can be limitedly rotated relative to the frame 16. One end of the second elastic member 15 is fixedly connected to the rear brake rod 8, and the other end is fixedly connected to the frame 16, so as to ensure that after the user releases the brake pedal 4, the second elastic member 15 can quickly control the brake pedal 4 to reset.

[0053] When braking is required, the front brake 1 can be controlled to work independently through the holding mechanism 2 to provide braking force for the front wheel 17. By stepping on the driving block 41, when the braking driving force is output to the driving block 41, and the braking driving force is less than the elastic force of the first elastic member 12 and greater than the elastic force of the second elastic member 15, the rear brake rod 8 moves to control the rear brake 3 to work and provide braking force for the rear wheel 18 of the vehicle; until the braking driving force is greater than the elastic force of the first elastic member 12, the hydraulic mechanism starts to work, controls the front brake 1 to work, and provides braking force for the front wheel 17 of the vehicle. This allows the braking device to meet the use requirements of front and rear wheel combined braking, and each time the driving block 41 is stepped on for braking, the rear brake 3 starts to work before the front brake 1, which can prevent the front wheel 17 from locking in advance and ensure riding safety.

[0054] In the embodiment of the present application, the holding mechanism 2 is a front brake grip, the first elastic member 12 is a delay spring, and the second elastic member 15 is a delay spring.

[0055] like Figure 8 As shown, each embodiment of the present application generates a series of forces on the front brake 1 and the rear brake 3 through the brake pedal 4, which are distributed to the front brake 1 and the rear brake 3 in a certain proportion after spiral rotation, and there will be a certain delay effect when distributed to the front brake 1. In order to achieve the above-mentioned effect, the present application is internally composed of a set of rear brake drum brake kits and a set of hydraulic cylinders, wherein the rear brake drum brake kit connected to the rear brake 3 is controlled and output by the first rotating member 5, the rear brake pull rod 8, the first elastic member 15, etc.; in addition, the rear brake drum brake kit connected to the front The hydraulic mechanism of the brake 1 is controlled by the first rotating block 61, the piston rod 10, and the first elastic member 12. Before the hydraulic pressure distributed to the cylinder 9 by the first rotating block 61 is greater than the holding force of the first elastic member 12, no hydraulic pressure will be provided to the front brake 1; when the output hydraulic pressure is greater than the holding force of the first elastic member 12, the piston rod 10 moves backward, the valve body opens, and the output hydraulic pressure and the input hydraulic pressure are input and output in a 1:1 ratio, so there will be a certain delay effect when it is distributed to the front brake 1. The structure is simple, cost-saving, and easy to arrange.

[0056] Initially, when operating the brake pedal 4 to provide braking force to the front brake 1 and the rear brake 3, the first rotating member 5 rotates and the first rotating block 61 remains in its original state. The initial braking force only pulls the rear brake rod 8 to directly provide braking force to the rear brake 3. At this time, the piston rod 10 that transmits the braking force to the front brake 1 is not opened, and no hydraulic pressure is provided to the front brake 1; when the first rotating block 61 rotates to a certain angle, the hydraulic pressure entering the oil cylinder 9 is greater than the holding force of the first elastic member 12, and the piston rod 10 opens, the front brake 1 and the rear brake 3 provide braking force at the same time.

[0057] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit it. Although the present application has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present application.
