[0026] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art in the technical field of the present invention. The terms used in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more related listed items.
[0027] like Figures 1 to 4 The brake device of the electric scooter shown in the figure comprises a brake assembly 1, wherein the brake assembly 1 comprises a brake pad 11 and a brake mechanism 12; the outer wall of the brake pad 11 is cooperatively connected with a wheel hub; the brake mechanism 12 is located at the outer edge of the brake pad 11, and is connected to a fixing member 3 arranged at one end of the handle through a brake line 2, and a handbrake handle 4 is movably connected to the inner wall of the fixing member 3; wherein the brake pad 11 comprises an inner ring 111 and an outer ring 112 which are arranged concentrically, the inner ring 111 and the outer ring 112 are arranged coaxially and are not coplanar in the radial direction, a plurality of strain beams 5 which are equidistantly distributed along the circumference are connected between the inner ring 111 and the outer ring 112, an axial hole is arranged at the center of the inner ring 111, and mounting holes 6 are arranged on the side wall of the inner ring 111 along the circumference.
[0028] The implementation process of the utility model is to install the brake pads of the device on the front and rear wheels of the electric scooter. After completion, the device can be used normally. When the electric scooter is running normally, if it is necessary to stop, first hold the handbrake handle 4 installed on the handle, and drive the brake mechanism 12 to work by pulling the brake line 2, thereby braking the brake pad 11, and then braking the wheels connected to stop moving forward. The beneficial effect of the utility model is that the device can be installed on the front and rear wheels of the electric scooter and can be used normally. The design of the strain beam disperses the stress generated by the brake pad during braking, making it difficult for the brake pad to break easily. At the same time, by setting air holes and heat dissipation grooves on the brake pad, the brake pad has a strong heat dissipation capacity.
[0029] In the utility model, the braking mechanism 12 includes an adjusting member 121 and an adjusting head. The adjusting member 121 is arranged at one end close to the brake line 2. A connecting member 7 is provided on one side of the adjusting member 121. A connecting head 8 is provided on the outer wall of the connecting member 7. The connecting head 8 extends to the interior of the connecting member 7 and is connected to the braking member 9. The back of the braking member 9 is fixedly connected to the brake pad 11. The adjusting member 121 is arranged at one end close to the brake line 2, so that the user can conveniently adjust the tension of the brake line by operating the adjusting member 121, thereby realizing fine adjustment of the braking performance, improving the flexibility and convenience of adjustment, and helping to adapt to the needs of different usage scenarios and driving habits; the adjusting member 121, the connecting member 7, the connecting head 8 and the brake member 9 are combined together through a compact design, which not only reduces the volume of the overall structure, but also optimizes the space utilization rate, which is particularly important for vehicles with limited space such as scooters, and helps to keep the vehicle body light and compact; the outer wall of the connecting member 7 is provided with a connecting head 8, and the connecting head 8 extends to the inside of the connecting member 7 and is connected to the brake member 9, which enhances the connection stability between the components and reduces the safety hazards caused by loose connection or falling off. At the same time, a stable connection also helps to ensure the stability and reliability of the braking performance.
[0030] In this solution, the outer ring 112 is penetrated by a plurality of heat dissipation grooves 1121, which are evenly distributed along the circumference of the outer ring 112, and the opening shape of the heat dissipation grooves 1121 is a long strip, and the length direction of the opening of the heat dissipation grooves 1121 is inclined to the direction of the diameter of the brake pad 11 passing through the midpoint. The heat dissipation grooves 1121 are evenly distributed along the circumference of the outer ring 112, which can ensure that the heat generated by the brake pad during the braking process can be quickly and evenly dissipated to the surrounding environment, which helps to reduce the temperature of the brake pad and prevent performance degradation or damage caused by overheating. The opening shape of the heat dissipation grooves 1121 is a long strip, and the length direction of the opening is inclined to the direction of the diameter of the brake pad 11 passing through the midpoint, which helps to form a more effective airflow channel when the brake pad rotates, so that air can flow through the heat dissipation grooves more smoothly, further accelerating the dissipation of heat.
[0031] As a preferred embodiment of the above, a plurality of air holes 1122 are evenly spaced circumferentially on the disk surface of the outer ring 112, and the air holes 1122 are spaced apart from the heat dissipation grooves 1121. The addition of the air holes 1122 further increases the heat exchange area between the outer ring 112 and the surrounding environment. When the brake pad generates heat during braking, the heat can not only be dissipated through the heat dissipation grooves 1121, but also be quickly transferred to the outside of the outer ring through the air holes 1122, thereby accelerating the heat dissipation process. This dual heat dissipation mechanism significantly improves the heat dissipation efficiency and helps to maintain a stable operating temperature of the brake pad; the interval arrangement of the air holes 1122 and the heat dissipation grooves 1121 helps to form a more complex and effective airflow channel. When the brake pad rotates, air can enter the inner part of the outer ring through the air holes 1122, and mix and exchange with the hot air in the heat dissipation grooves 1121, which helps to accelerate the transfer and dissipation of heat and further improve the heat dissipation effect.
[0032] In the present invention, the side of the outer ring 112 is provided with notches 10 for machining and positioning the brake pad 11 at intervals along the circumferential direction, and adjacent notches 10 are connected by arc surfaces. The notches 10 provide a clear positioning reference for machining the brake pad 11. During the manufacturing process, these notches can be used as reference points for fixtures or positioning tools to ensure that the brake pad can be accurately installed on the outer ring 112, thereby improving machining accuracy and efficiency and reducing errors and waste caused by inaccurate positioning.
[0033] As a preferred embodiment of the above, the notch 10 is V-shaped. The V-shaped notch design helps to better disperse stress when the brake pad is working. Compared with a straight or circular notch, the V-shaped notch can guide the stress to be gradually released along its two sides when subjected to force, avoiding the formation of a stress concentration point at the notch, helping to extend the service life of the brake pad and the outer ring, and improving the stability and reliability of the overall structure.
[0034] In the present invention, the mounting hole 6 on the side wall of the inner ring 111 is a countersunk hole. The countersunk hole allows the fastener to remain flush with the surface of the workpiece or slightly below the surface after installation, thereby avoiding collision and friction between the fastener head and other components, reducing interference problems during assembly, and improving assembly accuracy and quality.
[0035] In the present invention, the handbrake handle 4 is connected with the brake line 2 through the fixed part 3. The fixed part 3 serves as a connecting bridge between the handbrake handle 4 and the brake line 2, ensuring a stable connection between the two and avoiding the problem of brake failure caused by loose connection or falling off; the connection through the fixed part 3 makes the installation process of the handbrake handle 4 and the brake line 2 simpler and faster. At the same time, when maintenance or replacement of parts is required, it can also be conveniently disassembled and reassembled, which improves the efficiency and convenience of maintenance.
[0036] In the present invention, the strain beam 5 is connected to the inner side of the outer ring 112 through the connecting ring 13. The connecting ring 13, as a connecting medium between the strain beam 5 and the outer ring 112, can ensure a stable connection between the two, help enhance the stability of the entire structure, prevent loosening or deformation during the force process, thereby ensuring the normal operation of the equipment and the reliability of long-term use.
[0037] In the present invention, the fixing member 3 is connected to the handle through mutually symmetrical semicircular fixing plates, and the semicircular fixing plates are provided with connecting holes. The mutually symmetrical semicircular fixing plates can provide uniform supporting force, ensure that the connection between the fixing member 3 and the handle is stable and reliable, help to disperse the force, reduce the risk of damage caused by stress concentration, and thus improve the stability of the connection.

The above embodiments and the description are only for explaining the principle of the present invention.
