Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of non-motor vehicle brake accessories, in particular to a disc brake for preventing collision. BACKGROUND

[0002] Bicycles and electric bicycles have become more and more widely used as a means of transportation for people to travel due to their low price, flexible driving, and simple driving technology. The brake device, as an indispensable safety component of bicycles and electric bicycles, is directly related to the safety of people's lives.

[0003] At present, disc brakes are divided into mechanical disc brakes and oil pressure disc brakes. The mechanical disc brake relies on the pulling force of the brake wire to make the brake pad in the caliper rub and clamp the disc, thereby producing a braking effect. The mechanical disc brake is widely welcomed due to its convenience in compatibility, easy installation, and low maintenance cost in the later period. Therefore, it is generally configured to some small vehicles with relatively simple structure, and thus these vehicles mostly do not have excessive protective structures, especially at the brake installation position. When the vehicle falls or rolls over, the rocker arm and its fastening part of the disc brake protrude outward from the main body of the disc brake, which will directly impact the rocker arm or the rocker arm fastening part of the disc brake, thereby causing deformation of the disc brake rocker arm or damage to the internal driving mechanism connected thereto, and even causing brake failure.

[0004] For example, CN201721706699.9 disc brake for electric vehicle and electric vehicle, by setting a protective disc for blocking external objects from impacting the disc brake pad, external objects will impact the disc brake pad and cause deformation of the disc brake pad. For example, CN202022248974.5 disc brake for motor vehicle, by setting a high-strength layer to improve the overall strength and wear resistance, the disc brake has improved anti-collision strength when subjected to impact. The above structure improves the anti-collision performance of the disc brake, but the structure and production process are complex, and the overall cost is increased.

[0005] Therefore, it is urgent for a disc brake with a new anti-collision structure to overcome the above problems. SUMMARY

[0006] In view of the deficiencies of the prior art, the present application provides a disc brake for preventing collision, which solves the problem of deformation of the disc brake rocker arm or damage to the internal driving mechanism connected thereto caused by the impact of the vehicle falling or rolling over on the disc brake, which may even cause brake failure.

[0007] In order to achieve the above purpose, the present application is realized by the following technical scheme:

[0008] This invention relates to a novel anti-collision disc brake, comprising a disc brake body with a clamping portion on its main body. A first mounting portion and a second mounting portion are located on both sides of the clamping portion. Brake pads are located on the two opposite end faces of the clamping portion. A drive assembly is located within the first mounting portion, with one end abutting against the brake pads and the other end securely connected to a rocker arm. The disc brake body also features an anti-collision structure, which consists of a protruding structure on the outer end face of the first mounting portion and a limiting boss located below the protruding structure. The protruding structure extends beyond the top of the rocker arm, and the limiting boss is located outside the mounting base to prevent the protruding structure from being impacted and causing the disc brake body to move relative to the frame.

[0009] A further improvement is that the convex structure is formed by extending longitudinally or offset longitudinally by a distance from one side of the first mounting part.

[0010] A further improvement is that the extension height H of any of the convex structures is 10-20mm.

[0011] Further improvements include: the mounting base is symmetrically arranged laterally on both sides of the first mounting part and connected to the outward protrusion structure; the mounting base is provided with a limiting boss at the position adjacent to the outward protrusion structure; the mounting base is also provided with an elongated oval mounting hole and anti-slip protrusions; the anti-slip protrusions are evenly distributed on the surface of the mounting base; and the limiting boss is located above the mounting hole.

[0012] Further improvements include: the disc brake body is also provided with a brake cable adjustment arm, the adjustment arm is provided with a brake cable adjustment structure, one end of the rocker arm is provided with a polygonal mounting hole and is fastened to the outer end face of the first mounting part by bolts, the other end is bent in the opposite direction of the outward convex structure and adapted to the brake cable adjustment arm, and the bent end of the rocker arm is provided with a brake cable mounting structure.

[0013] Further improvements include: the first mounting part and the second mounting part are coaxially arranged; the second mounting part is provided with an adjustment device to adjust the relative gap of the brake pads; the outer side of the second mounting part is also provided with a set screw mounting threaded through hole; the adjustment device is an adjustment column fitted in the second mounting part; the outer side of the adjustment column is provided with threads to fit the second mounting part; and the inner end face of the adjustment column abuts against the brake pads.

[0014] A further improvement is that a return spring is provided between the rocker arm and the first mounting part, the drive assembly consists of a stroke cam, a push rod and a rolling element, a rolling element movement slide is provided between the stroke cam and the push rod, and the drive assembly is rotatably connected in the first mounting part.

[0015] A further improvement is that the disc brake body is a one-piece die-cast structure.

[0016] The beneficial effects of this invention are:

[0017] 1. The disc brake body has an outwardly extending convex structure with an anti-collision structure at one end of the rocker arm, and a limiting boss symmetrically set on the mounting base below the convex structure. When the vehicle falls or rolls over and impacts the disc brake, the outwardly extending convex structure beyond the top of the rocker arm is the first to be impacted, effectively protecting the rocker arm and the drive components connected to the rocker arm from damage. At the same time, due to the presence of the limiting boss on the mounting base, the disc brake body is prevented from deviating further from its original installation position relative to the frame after the impact, preventing the brake device from failing after the impact. This effectively prevents brake failure caused by accidents and extends the service life of the disc brake device.

[0018] 2. The mounting base surface is provided with anti-slip protrusions, which play a role in buffering and preventing slippage when the external protrusion structure is impacted, while also increasing the frictional resistance relative to the frame;

[0019] 3. The rocker arm is designed to bend towards the disc brake body, effectively preventing the rocker arm from being directly impacted and damaged.

[0020] The disc brake system features an outward-protruding structure, a limiting boss, anti-slip protrusions, and a bending rocker arm, which effectively prevent impacts and improve the overall safety and service life of the disc brake. Attached Figure Description

Detailed Implementation

[0028] To enhance understanding of the present invention, the invention will be further described in detail below with reference to the accompanying drawings. This embodiment is only used to explain the invention and does not constitute a limitation on the scope of protection of the invention.

[0029] In the description of this invention, it should be understood that the terms "center", "upper", "lower", "front", "rear", "left", "right", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the combination or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limiting this invention.

[0030] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments:

[0031] like Figures 1-5 An embodiment of an anti-collision disc brake is provided, including a disc brake body 1, a drive assembly 2, a brake pad 3, an adjustment device, a rocker arm 5, and a return spring 6. The disc brake body 1 is provided with a clamping part 11, and a first mounting part 12 and a second mounting part 13 are provided on both sides of the clamping part 11. The brake pad 3 is provided on the two opposite end faces of the clamping part 11. The drive assembly 2 is provided inside the first mounting part 12. One end of the drive assembly 2 abuts against the brake pad 3, and the other end is fastened to the rocker arm 5 and connected to the outer end face of the first mounting part 12. The disc brake body 1 is also provided with an anti-collision structure, which consists of an outward protrusion structure 14 provided on the outer end face of the first mounting part 12 and a limiting boss 15 provided below the outward protrusion structure 14. The outward protrusion structure 14 is formed by extending longitudinally from one side of the clamping part 11 of the first mounting part 12. The outward protrusion structure 14 extends beyond the top of the rocker arm 5 and the drive assembly 2. The limiting boss 15 is provided on the outside of the mounting seat 16 to prevent the outward protrusion structure 14 from being impacted and causing displacement of the disc brake body 1 relative to the frame. The disc brake body 1 has an anti-collision structure at one end of the rocker arm 5. The outwardly extending protruding structure 14 and the limiting protrusion 15 symmetrically arranged on the mounting base 16 below the protruding structure 14 are combined together. When the vehicle falls or rolls over and impacts the disc brake, the outwardly extending protruding structure 14, which is fixedly connected to the top of the rocker arm 5, is the first to be impacted, effectively protecting the rocker arm 5 and the drive assembly 2 connected to the rocker arm 5 from damage. At the same time, due to the presence of the limiting protrusion 15 on the mounting base 16, the disc brake body 1 is prevented from further deviating from its original installation position relative to the frame that is fixedly connected to it and from impacting the disc brake disc after the impact. This effectively prevents brake failure caused by the impact and extends the service life of the disc brake device.

[0032] More preferably: the mounting base 16 is laterally symmetrically arranged on both sides of the first mounting part 12 and connected to the outward protrusion structure 14. A limiting boss 15 is provided adjacent to the mounting base 16 and the outward protrusion structure 14. The mounting base 16 also has an elongated oval mounting hole 161 and anti-slip protrusions 162. The anti-slip protrusions 162 are evenly distributed on the surface of the mounting base 16, and the limiting boss 15 is located above the mounting hole 161. The laterally symmetrical arrangement of the mounting base 16 on both sides of the first mounting part 12 and connected to the outward protrusion structure 14 results in a compact and high-strength disc brake body 1. The anti-slip protrusions 162 provide cushioning and anti-slip protection when the outward protrusion structure 15 is impacted, while also increasing the frictional resistance relative to the frame. The elongated oval mounting hole 161 facilitates installation. The limiting boss 15 can be provided with spaced protrusions, and the height of the limiting boss 15 can provide cushioning and vibration damping.

[0033] More preferably, the disc brake body 1 is further provided with a brake cable adjustment arm 17, and the adjustment arm 17 is provided with a brake cable adjustment structure 8. One end of the rocker arm 5 is provided with a polygonal mounting hole and is fastened to the outer end face of the first mounting part 12 by bolts. The other end is bent at an angle towards the second mounting part 13 and is adapted to the brake cable adjustment arm 17. The bent end of the rocker arm 5 is provided with a brake cable mounting structure 7. The rocker arm 5 is set to bend towards the disc brake body 1, which effectively avoids the rocker arm 5 being directly impacted and damaged.

[0034] More preferably, the outer extension height H of the convex structure 14 is 10-20mm. This ensures that the convex structure 14 contacts the ground during a tipping impact; preferably, the top of the rocker arm 5 is installed on the inside of the line connecting the outermost end of the rocker arm 5 at the bend and the highest point of the convex structure 14, ensuring that the rocker arm 5 is protected from direct impact that could cause damage to the disc brake.

[0035] More preferably, the first mounting part 12 and the second mounting part 13 are coaxially arranged. The second mounting part 13 is provided with an adjusting device to adjust the relative gap of the brake pads 3. The outer side of the second mounting part 13 is also provided with a set screw 9 and a threaded through hole 131. The adjusting device is an adjusting column 4 fitted into the second mounting part 13. The outer side of the adjusting column 4 is threaded to fit the second mounting part 13, and the inner end face of the adjusting column 4 abuts against the brake pads 3. This ensures reliable and convenient adjustment of the brake gap.

[0036] More preferably, a return spring 6 is also provided between the rocker arm 5 and the first mounting part 12. The drive assembly 2 consists of a stroke cam 21, a push rod 22, and a rolling element 23. A movement slide for the rolling element 23 is provided between the stroke cam 21 and the push rod 22. The drive assembly 2 is rotatably connected within the first mounting part 12. This ensures reliable overall braking and reset of the disc brake.

[0037] Even better: The disc brake body 1 is a one-piece die-cast structure. The overall structure has high strength and is lightweight.

[0038] Example 2:

[0039] like Figure 5 As shown: Other structures are the same as in Embodiment 1, except that the outwardly protruding structure 14 is formed by extending longitudinally outward from one side of the clamping part of the first mounting part 12 by a certain distance. In this structure, the limiting boss 15 is directly formed by the offset part, which fits against the outer side of the disc brake body 1, resulting in a larger contact surface with the frame and better impact resistance. Furthermore, protrusions are provided at intervals at the contact position between the limiting boss 15 and the frame, which can play a role in buffering and damping vibration.

[0040] The brake pad 3 of this application is connected to the push rod 22 of the drive assembly 2 and the adjusting column 4 by a matching magnet and drives them back and forth. The anti-collision disc brake structure disclosed in this application is generally suitable for small vehicles, such as children's scooters, small electric vehicles, etc.

[0041] The same anti-collision structure can be applied to other disc brake bodies, such as disc brakes for bicycles, disc brakes for electric vehicles, or hydraulic pump disc brake structures.

[0042] The embodiments disclosed herein are preferred embodiments, but are not limited thereto. Those skilled in the art can readily grasp the spirit of the present invention based on the above embodiments and make different extensions and variations, but as long as they do not depart from the spirit of the present invention, they are all within the protection scope of the present invention.
