Description

Technical Field

[0001] This utility model relates to the field of disc brake technology, and in particular to an explosion-proof disc brake device. Background Technology

[0002] With the rise in popularity of cycling, disc brakes have become the mainstream configuration for modern mid-to-high-end road bikes. Continuous or frequent braking can cause the brake discs to overheat rapidly, potentially leading to them bursting.

[0003] At the same time, dust, mud and other contaminants easily adhere to the surface of the brake disc. These impurities will accelerate wear, affect braking stability, and even generate abnormally high temperatures due to changes in friction conditions. Utility Model Content

[0004] This invention provides an explosion-proof disc brake device, which solves the technical problem that continuous or frequent braking can cause the brake disc temperature to rise sharply, which may further lead to the brake disc bursting.

[0005] To achieve this technical objective, the present invention adopts the following solution: an explosion-proof disc brake device, comprising a brake disc body, a flow guiding mechanism, and a heat dissipation mechanism;

[0006] The brake disc body has a protrusion integrally formed in the middle, which is used to connect with the wheel hub.

[0007] The flow guiding mechanism is located on the brake disc body and is used to guide airflow and water flow;

[0008] The heat dissipation mechanism is located on the brake disc body and the boss.

[0009] Furthermore, the flow guiding mechanism includes a flow guiding ring groove and a connecting groove formed on the brake disc body;

[0010] The flow guide groove is located on the outer side of the bottom of the boss;

[0011] Multiple connecting grooves are arranged radially and connected to the flow guiding ring groove.

[0012] Furthermore, the heat dissipation mechanism includes heat dissipation cavities, which are formed on the side wall of the boss and extend radially along the boss, with multiple heat dissipation cavities distributed at equal intervals along the circumference of the boss.

[0013] The heat dissipation cavity has a through slot for communicating with the outside.

[0014] Furthermore, the heat dissipation mechanism also includes heat dissipation grooves formed on the brake disc body, which penetrate the brake disc body.

[0015] Furthermore, the heat dissipation grooves extend radially along the brake disc body, and multiple heat dissipation grooves are provided at equal intervals between adjacent connecting grooves.

[0016] Furthermore, the total area of ​​the heat dissipation grooves is greater than half the area of ​​the brake disc body.

[0017] Furthermore, the boss has multiple equally spaced screw holes.

[0018] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0019] The explosion-proof disc brake device disclosed in this utility model is equipped with a flow guiding mechanism. During the driving of a road vehicle, the flow guiding mechanism can guide the airflow to dissipate heat from the brake disc body, and can also guide the water flow to clean foreign objects from the brake disc body in rainy weather. By setting up a heat dissipation mechanism, the temperature of the brake disc body is further controlled to prevent the brake disc body from bursting. Attached Figure Description

[0024] To fully understand the purpose, features and effects of this utility model, the following specific embodiments will be used to describe this utility model in detail, but this utility model is not limited thereto.

[0025] like Figures 1 to 2 As shown, this utility model provides an explosion-proof disc brake device, including a brake disc body 1, a flow guiding mechanism 2, and a heat dissipation mechanism 3. A boss 4 is integrally formed in the middle of the brake disc body 1, which is used for connection with the wheel hub. The flow guiding mechanism 2 is disposed on the brake disc body 1 and is used to guide airflow and water flow.

[0026] The flow guiding mechanism 2 includes a flow guiding ring groove 21 and a connecting groove 22 formed on the brake disc body 1. The flow guiding ring groove 21 is located on the outer side of the bottom of the boss 4, and the multiple connecting grooves 22 are radial and communicate with the flow guiding ring groove 21.

[0027] During riding, the wind blowing from both sides of the bicycle creates airflow within the guide ring groove 21. This airflow exits the brake disc body 1 via the connecting groove 22, thereby accelerating airflow on the brake disc body 1 and effectively dissipating heat. In rainy weather, rainwater accumulates in the connecting groove 22. Under the centrifugal force of the rotating brake disc body 1, the rainwater exits through the connecting groove 22. During this process, foreign objects are carried away from the brake disc body 1 by the water flow, effectively cleaning the brake disc body 1 and preventing foreign objects from adhering to it and affecting braking performance in rainy weather.

[0028] A heat dissipation mechanism 3 is disposed on the brake disc body 1 and the boss 4. The heat dissipation mechanism 3 includes a heat dissipation cavity 31, which is formed on the side wall of the boss 4 and extends radially along the boss 4. Multiple heat dissipation cavities 31 are evenly distributed around the circumference of the boss 4. The heat dissipation cavity 31 is provided with a through groove 32 for communicating with the outside.

[0029] By setting the through slot 32 and the heat dissipation cavity 31, airflow can enter the interior of the boss 4, thereby dissipating heat from the boss 4.

[0030] Furthermore, the heat dissipation mechanism 3 also includes heat dissipation grooves 33 formed on the brake disc body 1, which penetrate the brake disc body 1. The heat dissipation grooves 33 extend radially along the brake disc body 1, and multiple heat dissipation grooves 33 are equally spaced between adjacent connecting grooves 22.

[0031] Preferably, the total area of ​​the heat dissipation grooves 33 is greater than half the area of ​​the brake disc body 1.

[0032] By setting up heat dissipation slots 33, the airflow velocity on the brake disc body 1 can be effectively increased, thereby improving heat dissipation capacity. At the same time, by setting up more heat dissipation slots 33, the force of the wind on the side of the vehicle on the brake disc body 1 can be effectively reduced, thereby effectively reducing the force of the crosswind on the vehicle and preventing the vehicle from being blown by the wind.

[0033] As a method of connecting the boss 4 to the wheel hub, the boss 4 has multiple equally spaced screw holes 41. In use, the boss 4 can be fixed in the predetermined position using bolts.

[0034] Finally, it should be noted that the above-listed embodiments are merely preferred embodiments of the present invention. Of course, those skilled in the art can make modifications and variations to the present invention. If such modifications and variations fall within the scope of the claims of the present invention and their equivalents, they should be considered as being within the protection scope of the present invention.
