AI Technical Summary
In the prior art, the handle of the manual release structure requires multiple slots, which complicates the manufacturing process.
The handle design features a number of grooves, which are formed by the first handle surface being recessed into the second handle surface and the second handle surface protruding away from the first handle surface. This replaces the traditional recessed holes and is processed by stamping or bending. The design of the stamping die simplifies the processing.
This eliminates the need for multiple slot and hole machining processes, preventing structural weakness, reducing machining costs, and making the handle thinner and lighter, thus improving structural strength and preventing deformation of the blank edge.

[0059] The positional relationship of first elastic member 262 and release column 263 can have multiple layout modes, for example, as Figure 8As shown, the first limiting hole 213 is a through hole, located at the center of the stator 21. The release pin 263 passes through the first limiting hole 213. A first elastic member 262 is provided and sleeved on the outer periphery of the release pin 263. One end of the first elastic member 262 abuts against the stepped abutment portion 214, and the other end abuts against the release step 2631. For example, as... Figure 9 As shown, multiple first elastic elements 262 and first limiting holes 213 are provided. The release post 263 passes through the central hole of the stator 21. Multiple blind-hole-shaped first limiting holes 213 are provided around the release post 263 on the stator 21. A first elastic element 262 is provided in each first limiting hole 213.

[0061] It is understood that the handle 10 and the release post 263 can be connected by means of a first fastener 265, snap-fit, welding, riveting, etc. The first fastener 265 can be a screw, bolt, rivet, etc. The number of first fasteners 265 can be one or more to ensure the connection stability between the handle 10 and the release post 263.
[0062] In addition, such as Figure 2 , Figure 3 , Figure 7 and Figure 10As shown, the handle 10 can be integrally formed with the force applying part 17 to facilitate the rotation of the handle 10, of course, as Figure 11 As shown, the release column 263, the handle 10 and the additional force applying part 266 can be connected together by fasteners, and the rotation of the handle 10 can also be realized by operating the force applying part 266.
[0063] The brake 20 provided by the embodiment of the utility model has at least the following technical effects: compared with the prior art, the handle 10 has a plurality of rib grooves 13, the rib groove 13 is recessed from the first handle surface 11 to the second handle surface 12 and the second handle surface 12 is convex in the direction away from the first handle surface 11, the rib groove 13 replaces the traditional nest groove hole, the machining process of processing a plurality of nest groove holes is omitted, the structural strength weakening caused by multiple punching is avoided, and the machining cost can also be reduced, since the rib groove 13 is formed by stamping, bending and the like of the handle 10 itself, the handle 10 can have a thinner thickness, the weight of the handle 10 is reduced, and then the weight of the brake 20 is reduced, and the shape of the rib groove 13 can improve the structural strength of the handle 10.
[0064] Please refer to Figures 7 to 11 In some embodiments, the end surface of the stator 21 away from the armature 22 is also provided with a mounting hole 212, and the manual release assembly 26 further comprises a limiting column 264, the limiting column 264 is arranged in the mounting hole 212 and can abut against the handle 10. Specifically, one part of the limiting column 264 is located in the stator 21, and the other part of the limiting column 264 is located outside the stator 21, the shape of the handle 10 is designed so that the handle 10 can abut against or separate from the limiting column 264 in the rotation process, for example, the handle 10 has a long force applying part 17, the force applying part 17 can abut against the limiting column 264 in the rotation process, of course, the limiting column 264 can be arranged on one side or both sides of the force applying part 17, and for another example, the handle 10 can have a special abutting part, the abutting part can abut against the limiting column 264 in the rotation process, and then the rotation angle of the handle 10 is limited.
[0065] Please refer to Figure 7 , Figure 10 and Figure 11 In some embodiments, the brake 20 further comprises a micro switch 27 arranged on the outer periphery of the stator 21, the micro switch 27 is connected in series with the coil 25, or connected in parallel with the coil 25, or configured to be connected with the controller, and the handle 10 can trigger the micro switch 27 in the rotation process. By arranging the micro switch 27, the handle 10 can transmit the signal that the friction disc 23 is released or pressed in the rotation.
[0066] Specifically, the micro switch 27 can be connected in series with the coil 25, in which case the micro switch 27 can control the energization and de-energization of the coil 25; the micro switch 27 can also be connected in parallel with the coil 25, in which case the micro switch 27 can adjust the current signal of the coil 25; the micro switch 27 can also be connected with the controller without being connected with the coil 25, and after being triggered by the handle 10, the micro switch 27 can provide a signal of the current posture of the handle 10 to the controller, so that the controller determines the opening and closing of the micro switch 27.
[0067] It can be understood that the handle 10 can be set to represent that the friction disc 23 is in the released posture when the micro switch 27 is triggered, and the handle 10 can be set to represent that the friction disc 23 is in the compressed posture when the micro switch 27 is triggered. The handle 10 can also be set to represent that the friction disc 23 is in the compressed posture when the micro switch 27 is triggered, and the handle 10 can be set to represent that the friction disc 23 is in the released posture when the micro switch 27 is triggered. The above triggering mode mainly depends on the initial posture of the handle 10.
[0068] In order to facilitate the handle 10 to trigger the micro switch 27, please refer to Figures 1 to 7 , Figure 10 and Figure 11 In some embodiments, the micro switch 27 has a sensing portion 271, and the handle 10 has a triggering portion 18, which can be in contact with or separated from the sensing portion 271. The sensing portion 271 can be in the form of a sheet, a block, a strip, a groove, etc., and the triggering portion 18 can be in the form of a sheet, a block, a strip, a groove, etc. During the rotation of the handle 10, the triggering portion 18 can be in contact with or separated from the sensing portion 271 to indicate that the friction disc 23 is in the released posture or the compressed posture.
[0069] For example, the handle 10 can be set to represent that the friction disc 23 is in the released posture when the micro switch 27 is triggered. Specifically, when the handle 10 is not rotated to release, the triggering portion 18 is away from the sensing portion 271; when the handle 10 is rotated to release, the triggering portion 18 gradually approaches the sensing portion 271; when the release is completed, the triggering portion 18 compresses the sensing portion 271, and the sensing portion 271 obtains a corresponding signal through mechanical or electronic communication to realize the on-off control of the micro switch 27.
[0070] In addition, please refer to Figures 12 to 17The utility model embodiment further provides a punch die 30 suitable for forming the handle 10 of any one of the above embodiments, comprising: an upper die plate 31 having a punch male die 311; a lower die plate 32 having a punch female die 321, the punch male die 311 and the punch female die 321 jointly forming the shape of the handle 10; and a flat die plate 33 arranged around the outer periphery of the punch male die 311 and stacked between the upper die plate 31 and the lower die plate 32, the flat die plate 33 being connected to the upper die plate 31 by a second fastener 34, and the flat die plate 33 and the upper die plate 31 having a preset gap X in the punching direction.
