The center of the motor rear shaft through hole (9) coincides with the center of the encoder mounting plate (8). The outer circular surface of the encoder mounting plate (8) is provided with multiple mounting plate lugs (10), and the front of the mounting plate lugs (10) is provided with a mounting plate lug through hole (11) that passes through both sides of the mounting plate lugs (10). After the mounting plate lug through hole (11) and the corresponding clamp lug through hole (6) are connected one by one, the encoder mounting plate (8) is fixedly installed on the back side of the clamp (4) by the support rod (12) and bolt (13). The encoder mounting plate (8) is located on the outside of the motor fan blade (14). The motor rear shaft (15) passes through the motor rear shaft through hole (9), and the end of the motor rear shaft (15) extends out of the outer side of the encoder mounting plate (8).

Since the brake motor handle has a stroke requirement when braking, the brake motor handle hole is a strip-shaped hole (the length is several times the width). With such a brake motor handle hole, the hands of the staff (such as equipment debugging and maintenance personnel) may be scratched by the metal burrs on the edge of the hole when operating the handle, which means that the safety of use is relatively poor. In addition, since the strip-shaped hole is relatively large, there is a certain probability that foreign objects (such as tools or small parts) may accidentally fall into the motor. Utility Model Content

[0003] Design objective: To design a rubber pad for the handle hole of a brake motor that not only has relatively good safety, but also prevents foreign objects (such as tools and small parts) from falling into the motor, and has a long service life.

[0004] Design scheme: To achieve the above design objectives.

[0005] 1. The perforated pad body is provided with slots around its four sides. The upper and lower end faces of the perforated pad body are respectively provided with a groove, and the distance between the bottom surfaces of the two grooves is 0.95mm-1.05mm. The bottom surface of the groove on the upper end face is provided with an "I"-shaped through hole, which extends downward and penetrates the bottom surface of the groove on the lower end face. The length of the "I"-shaped through hole matches the length of the groove, and the width of the "I"-shaped through hole is 0.45mm-0.55mm. The design of the perforated pad body being integrally molded from rubber is one of the technical features of this utility model. The purpose of this design is as follows: The perforated pad body has grooves around its four sides; the upper and lower ends of the perforated pad body each have a groove with a distance of 0.95mm-1.05mm between the bottom surfaces of the two grooves; the bottom surface of the groove on the upper end has an "I"-shaped through hole extending downwards through the bottom surface of the groove on the lower end; the length of the "I"-shaped through hole matches the length of the groove, and the width of the "I"-shaped through hole is 0.45mm-0.55mm; the perforated pad body is integrally molded from rubber. In use, a rubber pad for the brake motor handle hole passes through the brake motor handle hole. The edge and the slot are fitted together to fit inside the brake motor handle hole. This prevents workers (such as equipment debugging and maintenance personnel) from being scratched by the metal burrs on the edge of the hole when operating the handle, thus ensuring relatively good safety. In addition, the brake motor handle extends out of the brake motor handle hole through a "I"-shaped through hole. Because the rubber pad of the brake motor handle hole is made of rubber, it has good elasticity. This rubber pad of the brake motor handle hole can fill most of the gaps between the brake motor handle and the brake motor handle hole while ensuring the stroke requirements of the brake motor handle, preventing foreign objects (such as tools and small parts) from accidentally falling into the motor.

[0006] 2. The design of a 5.50mm thickness for the hole pad body and a 1.60mm width for the slot is the second technical feature of this utility model. The purpose of this design is to ensure a secure fit between the edge of the brake motor handle hole and the slot while controlling the production cost of the brake motor handle hole rubber pad.

[0007] 3. The design of using EPDM rubber as the rubber is the third technical feature of this utility model. The purpose of this design is that the rubber is EPDM rubber, and a brake motor handle hole rubber pad made of EPDM rubber not only has excellent weather resistance, but also excellent heat resistance, good water resistance and chemical resistance, as well as high elasticity and low permanent compression set, thus maintaining its performance for a long time, i.e., a long service life.

[0008] 4. The design of rounded corners on the four sides of the perforated pad body is the fourth technical feature of this utility model. The purpose of this design is that the rounded corners on the four sides of the perforated pad body facilitate installation and give it a softer appearance.

[0009] Technical solution: A rubber pad for a brake motor handle hole, comprising a pad body, wherein the pad body is provided with grooves around its four sides, and the upper and lower ends of the pad body are respectively provided with a groove, the distance between the bottom surfaces of the two grooves being 0.95mm-1.05mm. The bottom surface of the groove on the upper end is provided with an "I"-shaped through hole, which extends downward and penetrates the bottom surface of the groove on the lower end. The length of the "I"-shaped through hole matches the length of the groove, and the width of the "I"-shaped through hole is 0.45mm-0.55mm; the pad body is integrally molded from rubber.

[0010] Compared with the prior art, the rubber pad for the handle hole of the brake motor not only has relatively good safety, but also can prevent foreign objects (such as tools and small parts) from falling into the motor, and has a long service life. Attached Figure Description

[0016] Example 1: Refer to Appendix Figures 1-5 A rubber pad for a brake motor handle hole includes a pad body 1. The pad body 1 has grooves 2 around its perimeter. The upper and lower surfaces of the pad body 1 each have a recess 3, with a distance of 0.95mm-1.05mm between the bottom surfaces of the two recesses 3. The bottom surface of the recess 3 on the upper surface has an "I"-shaped through hole 4 extending downwards through the bottom surface of the recess 3 on the lower surface. The length of the "I"-shaped through hole 4 matches the length of the recess 3, and its width is 0.45mm-0.55mm. The pad body 1 is integrally molded from rubber. The thickness of the pad body 1 is 5.50mm, and the width of the grooves 2 is 1.60mm.

[0017] Preferably, the distance between the bottom surfaces of the two grooves 3 is 1.00 mm; the width of the "I"-shaped through hole 4 is 0.50 mm. The rubber is EPDM rubber. A brake motor handle hole rubber pad made of EPDM rubber has excellent weather resistance: it has strong resistance to ultraviolet rays, ozone, and weather changes, making it an ideal choice for outdoor applications; a brake motor handle hole rubber pad has excellent heat resistance: the continuous operating temperature range can reach -50°C to +150°C, fully meeting the heat environment generated during motor operation and braking; a brake motor handle hole rubber pad has good water resistance and chemical resistance: it has good stability against water, water vapor, cleaning agents, etc.; a brake motor handle hole rubber pad has high elasticity and low permanent compression deformation: it can maintain its performance for a long time.

[0018] The four corners of the hole pad body 1 are rounded to 5. This not only facilitates installation but also gives it a softer appearance. The rounded corners 5 on the hole pad body 1 are quarter-rounded, meaning that the two corners on the left are rounded to form semicircles, and the two corners on the right are rounded to form semicircles.

[0019] The following are the actual dimensions of a product developed by our company: the length of the hole pad body 1 is 69.00mm, the width of the hole pad body 1 is 24mm, the thickness of the hole pad body 1 is 5.50mm, the radius of the rounded corner 5 on the hole pad body 1 is 12.00mm, the width of the slot 2 is 1.60mm, and the distance from the slot 2 to the upper and lower end faces of the hole pad body 1 is equal, the depth of the slot 2 is 3.00mm, the two sides of the groove 3 in the length direction are straight edges and the two sides of the groove 3 in the width direction are semi-circular edges, the length of the straight edge is 45.00mm, the diameter of the semi-circular edge is 14.00mm, the depth of the groove 3 is 2.25mm, the distance between the bottom surfaces of the two grooves 3 is 1.00mm, the width of the "I"-shaped through hole 4 is 0.50mm, and the length of the "I"-shaped through hole 4 is 56.50mm.

[0020] It should be understood that although the above embodiments provide a relatively detailed textual description of the design concept of this utility model, these textual descriptions are merely simple textual descriptions of the design concept of this utility model, and not limitations on the design concept of this utility model. Any combination, addition, or modification that does not exceed the design concept of this utility model shall fall within the protection scope of this utility model.
