In addition, some aspects disclosed in the utility model can be used alone, or used in any appropriate combination with other aspects disclosed in the utility model.

[0023] Example 1

[0024] like Figure 1-4 As shown, it is the first embodiment of the utility model, which provides a novel rectangular spring for brake of a reduction motor, including an end seat 1, a brake disc 2 is arranged on the left side of the end seat 1, placement grooves 3 are opened around the left side of the end seat 1, a DC coil 4 is arranged in the inner cavity of the end seat 1, and a reset component 5 is arranged in the inner cavity of the placement groove 3;

[0025] The reset assembly 5 includes a connecting block 51, a rectangular spring 52 is fixedly connected to the right side of the inner cavity of the connecting block 51, and the other end of the rectangular spring 52 is fixedly connected to a movable plate 53, and one side of the movable plate 53 is fixedly connected to a movable block 54, and the rectangular spring 52 includes a substrate 521, a corrosion-resistant layer 522 and a wear-resistant layer 523.

[0026] like Figure 1 , 2As shown in Figure 4, the movable plate 53 and the movable block 54 can be pushed to one side by the reset elastic force of the rectangular spring 52, and the movable block 54 pushes the brake disc 2 so that the brake disc 2 can contact and rub with the brake pad to achieve the braking effect. The reset component 5 can be placed through the placement groove 3, and the brake disc 2 can be adsorbed by the end seat 1 in cooperation with the DC coil 4. During the adsorption, the brake disc 2 squeezes the movable block 54, so that the movable block 54 drives the movable plate 53 and the rectangular spring 52 to move and contract to one side, so that the rectangular spring 52 is deformed. The connecting block 51 can limit the rectangular spring 52 to ensure the stability of the rectangular spring 52, and the rectangular spring 52 is set as a rectangle, so that the force-bearing cross-section of the rectangular spring 52 is large, and the extrusion pressure can be well distributed and borne, thereby improving fatigue resistance and being able to maintain stable use for a long time. A protective layer is formed on the surface of the substrate 521 through the corrosion-resistant layer 522, which can improve the corrosion resistance of the rectangular spring 52, and the wear-resistant layer 523 can increase the roughness of the surface of the substrate 521, thereby enhancing the wear resistance of the rectangular spring 52.

[0027] Example 2

[0028] Reference Figure 1 and 2 , which is the second embodiment of the utility model, and this embodiment is based on the previous embodiment.

[0029] In this embodiment, the right side of the brake disc 2 contacts the end seat 1 , and the connecting block 51 is located in the inner cavity of the placement groove 3 and is movably connected to the inner cavity of the placement groove 3 .

[0030] A magnet sheet 511 is fixedly connected to the right side of the connection block 51 , and a side of the magnet sheet 511 away from the connection block 51 is magnetically connected to the inner wall of the placement slot 3 .

[0031] One end of the movable block 54 is fixedly connected with a rubber pad 541 , and a side of the rubber pad 541 away from the movable block 54 is in contact with the brake disc 2 .

[0032] like Figure 1 and 2 As shown, the magnet sheet 511 is driven into the inner cavity of the placement groove 3 by the connecting block 51, so that the magnet sheet 511 contacts the inner wall of the placement groove 3, and then the magnet sheet 511 is adsorbed on the inner wall of the placement groove 3 through ferromagnetic force, ensuring the stability of the placement of the connecting block 51 and preventing the connecting block 51 from automatically falling off. The rubber pad 541 contacts the brake disc 2, thereby protecting the brake disc 2 and alleviating the wear caused by the contact and collision between the movable block 54 and the brake disc 2.

[0033] Example 3

[0034] Reference Figure 3 and 4, which is the third embodiment of the utility model, and this embodiment is based on the previous two embodiments.

[0035] In this embodiment, both sides of the movable plate 53 are fixedly connected to the limiting blocks 531, and both sides of the inner cavity of the connecting block 51 are provided with limiting grooves 512. The limiting blocks 531 are located in the inner cavity of the limiting groove 512 and are slidably connected to the inner cavity of the limiting groove 512.

[0036] The corrosion-resistant layer 522 is sprayed on the surface of the substrate 521, and the wear-resistant layer 523 is sprayed on the side of the corrosion-resistant layer 522 away from the substrate 521. The wear-resistant layer 523 is a sandblasting coating, and the corrosion-resistant layer 522 is a polymer coating.

[0037] like Figure 3 and 4 As shown, the movable plate 53 can drive the limit block 531 to slide along the inner cavity trajectory of the limit groove 512 when moving, so as to limit the movable plate 53, and also ensure the stability of the rectangular spring 52 when deformed. The corrosion-resistant layer 522 is a polymer coating, so as to improve the corrosion resistance of the rectangular spring 52, and the wear-resistant layer 523 is a sandblasting coating, so as to improve the wear resistance of the rectangular spring 52, thereby extending the service life of the rectangular spring 52.

[0038] When in use, firstly, the DC coil 4 is powered to generate electromagnetic force, and the electromagnetic force can adsorb the brake disc 2, so that the brake disc 2 contacts the end seat 1. While being adsorbed, the brake disc 2 squeezes the movable block 54, so that the movable block 54 drives the movable plate 53 and the rectangular spring 52 to move and contract to one side, so that the rectangular spring 52 is deformed. During the deformation process, the connecting block 51 can limit the rectangular spring 52, so as to ensure the stability of the rectangular spring 52. Moreover, the rectangular spring 52 is set as a rectangle, so that the force-bearing cross-section of the rectangular spring 52 is large, and the extrusion pressure can be well distributed and borne. Thereby, fatigue resistance is improved, and stable use can be maintained for a long time. A protective layer is formed on the surface of the substrate 521 by the corrosion-resistant layer 522, which can improve the corrosion resistance of the rectangular spring 52, and the wear-resistant layer 523 can increase the roughness of the surface of the substrate 521, thereby enhancing the wear resistance of the rectangular spring 52. When the DC coil 4 is powered off, the electromagnetic force disappears, and the reset elastic force of the rectangular spring 52 can drive the movable plate 53 and the movable block 54 to one side, and the movable block 54 pushes the brake disc 2, so that the brake disc 2 can contact and rub with the brake pad, thereby achieving a braking effect.

The specific connection methods of each part adopt conventional means such as mature bolts, rivets, welding, etc. in the prior art. The machinery, parts and equipment all adopt conventional models in the prior art. The control method is automatic control through a controller. The control circuit of the controller can be implemented through simple programming by technicians in this field, which is common knowledge in the field. This application is mainly used to protect mechanical devices, so this application no longer explains the control method and circuit connection in detail.
