Description

Technical Field

[0001] This utility model relates to the field of motor technology, specifically to a braking structure. Background Technology

[0002] Electric motors are widely used in various industries such as automobiles, machine tools, military, and 3C products. They are essential for applications requiring vertical or oblique movement, emergency stops, and rapid positioning and precise control. A fast and accurate response is crucial for precise position control. Furthermore, the motor shaft should be locked in the event of a power outage or when the drive cannot provide braking, preventing accidents.

[0003] Currently, there is a lack of a braking structure that can achieve rapid response and braking of the motor by injecting gas, and is also easy to maintain. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a braking structure that facilitates rapid response of motor braking by injecting gas, thereby achieving braking, and also makes maintenance convenient.

[0005] This utility model achieves its purpose through the following technical solution:

[0006] A braking structure, characterized by comprising: a rotor; a brake ring disposed at the end of the rotor, the brake ring fitting the rotor, the brake ring having a set of evenly distributed stepped countersunk holes; a piston fitting the brake ring; a bottom cover fitting the piston, the bottom cover having a set of evenly distributed threaded holes and a set of evenly distributed brake air inlets; and a set of screws, each passing through a corresponding stepped countersunk hole and threadedly connected to a corresponding threaded hole. The piston moves upward, opening the brake ring to contact the rotor, thereby achieving a braking effect.

[0007] As a further limitation of this technical solution, the piston is provided with a shoulder, and the brake ring is provided with a conical surface, with the shoulder matching the conical surface. After the piston's shoulder contacts the conical surface, the shoulder opens the brake ring.

[0008] As a further limitation of this technical solution, the brake ring is provided with a set of evenly distributed expansion joints. This facilitates the restoration of the brake ring after it has been opened and the piston has been reset.

[0009] As a further limitation of this technical solution, the piston is provided with a set of spring holes, each of which contains a spring, and each spring contacts both the brake ring and the piston. The use of springs facilitates piston reset.

[0010] As a further limitation of this technical solution, the piston and the bottom cover form a sealed cavity, and a set of brake air inlets are respectively connected to the sealed cavity. The piston and the bottom cover are respectively provided with small O-rings and large O-rings corresponding to the sealed cavity. By injecting gas into the sealed cavity, the piston moves upward, expanding the brake rings to achieve the braking effect. O-rings are installed on both sides of the sealed cavity to achieve a seal and prevent air leakage.

[0011] As a further limitation of this technical solution, the bottom cover is provided with a small annular groove corresponding to the small O-ring, and the bottom cover is provided with a large annular groove corresponding to the large O-ring. The small and large annular grooves facilitate the installation of the O-ring.

[0012] Compared with related technologies, the brake structure provided by this utility model has the following beneficial effects:

[0013] (1) This device achieves braking effect by injecting gas into the sealed cavity, causing the piston to move upward and opening the brake ring;

[0014] (2) This device achieves sealing of the sealed cavity by installing O-rings on both sides of the sealed cavity to prevent air leakage;

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] A braking structure includes: a rotor 1; a brake ring 2 disposed at the end of the rotor 1, the brake ring 2 fitting to the rotor 1, the brake ring 2 having a set of evenly distributed stepped countersunk holes 14; a piston 7 fitting to the brake ring 2; a bottom cover 8 fitting to the piston 7, the bottom cover 8 having a set of evenly distributed threaded holes 16, and a set of evenly distributed brake air inlets 9; and a set of screws 4, each passing through a corresponding stepped countersunk hole 14 and threadedly connected to a corresponding threaded hole 16. When the piston 7 moves upward, it opens the brake ring 2 to contact the rotor 1, thereby achieving a braking effect.

[0025] The piston 7 is provided with a shoulder 11, and the brake ring 2 is provided with a conical surface 12. The shoulder 11 matches the conical surface 12. After the shoulder 11 of the piston 7 contacts the conical surface 12, the shoulder 11 opens the brake ring 2.

[0026] The brake ring 2 is provided with a set of evenly distributed expansion joints 15. This facilitates the restoration of the brake ring 2 after it has been opened and the piston 7 has been reset.

[0027] The piston 7 is provided with a set of spring holes 13, and a spring 3 is respectively provided in each spring hole 13. Each spring 3 contacts the brake ring 2 and the piston 7 respectively. By using springs 3, it is convenient to realize the return of piston 7.

[0028] The piston 7 and the bottom cover 8 form a sealed cavity 10. A set of brake air inlets 9 are connected to the sealed cavity 10. Small O-rings 5 ​​and large O-rings 6 are provided on the piston 7 and the bottom cover 8 corresponding to the sealed cavity 10. By injecting gas into the sealed cavity 10, the piston 7 moves upward, opening the brake ring 2 to achieve the braking effect. O-rings are installed on both sides of the sealed cavity 10 to seal it and prevent air leakage.

[0029] The bottom cover 8 is provided with a small annular groove 17 corresponding to the small O-ring seal 5, and the bottom cover 8 is provided with a large annular groove 18 corresponding to the large O-ring seal 6. The small annular groove 17 and the large annular groove 18 facilitate the installation of the O-ring seal.

[0030] The working principle of the brake structure provided by this utility model is as follows:

[0031] Install the small O-ring 5 and the large O-ring 6 into the small ring groove 17 and the large ring groove 18 respectively. Place the piston 7 on the bottom cover 8. Install the spring 3 into the spring hole 13 on the bottom cover 8. Then, use the screw 4 to lock the brake ring 2 onto the bottom cover 6.

[0032] When air is injected into the brake inlet 9, the piston 7 moves upward, expanding the brake ring 2 and widening the expansion joint 15. This causes friction between the brake ring 2 and the rotor 1, achieving the braking effect. When braking is no longer needed, the spring 3 returns to its original position, causing the piston 7 to return to its original position. Since the brake ring 2 is no longer subjected to the upward force of the piston 7, the expansion joint 15 returns to its original position, and the motor can then operate normally.

[0033] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
