Description

Technical Field

[0001] This utility model relates to the field of brake technology, and in particular, to a multi-directional manually released brake. Background Technology

[0002] The applicant’s earlier Chinese patent, CN220101873U, describes a manually release brake, which discloses that the axial sliding of the handle is achieved by the cooperation of a rotating handle and a drive component, and the handle can drive the pull rod to pull the armature away from the friction plate to achieve manual release of the brake.

[0003] However, the aforementioned brakes only have a form of releasing the brake by rotating the handle, which cannot meet the need for multi-directional manual release of the brake. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of the prior art and provide a multi-directional manually released brake.

[0005] The objective of this utility model is achieved through the following technical solution: A multi-directional manually released brake includes a brake body, a rotating handle rotatably disposed at the end face of the brake body, a transmission component adapted between the rotating handle and the brake body, a pull rod connected between the rotating handle and the brake disc of the brake body, and an actuating handle further disposed between the rotating handle and the brake body. The actuating handle is adapted to form a support point with the brake body. Pressing the first end of the actuating handle causes the second end of the actuating handle to deflect around the support point, thereby pushing the rotating handle.

[0006] Preferably, the transmission assembly includes a transmission pin disposed on the end face of the brake body, and a corresponding drive groove is provided on the end face of the rotary handle. The drive groove extends in an arc shape and its depth gradually decreases, and the end of the transmission pin is inserted into the drive groove.

[0007] Preferably, the transmission pins and the drive grooves are arranged in several groups along the circumferential direction.

[0008] Preferably, a spring is provided between the end face of the brake body and the end face of the rotary handle.

[0009] Preferably, the lever handle has a through-hole for the spring to pass through.

[0010] Preferably, a connecting post is provided on the end face of the brake body, and the spring is sleeved on the outside of the connecting post.

[0011] Preferably, a pin hole is provided through the lever handle, and the transmission pin passes through the pin hole.

[0012] Preferably, the rotary handle includes a pushing part, a supporting part, and a pressing part in sequence, wherein the supporting part has a bent structure, thereby forming the support point at the bend of the supporting part.

[0013] Preferably, the pushing part is disc-shaped.

[0014] Preferably, the transmission pin has a cavity, and a through hole communicating with the cavity is formed on the top surface of the transmission pin. A capsule is disposed in the cavity, and the liquid outlet of the capsule extends into the through hole. A sponge is also disposed in the through hole. A squeezing plate is also slidably disposed in the cavity. A groove communicating with the cavity is formed on the side wall of the transmission pin, and a push rod extending from the groove is provided on the side wall of the squeezing plate. A protrusion is provided on the side wall of the lever. When the lever is deflected, the protrusion can push the push rod to drive the squeezing plate to squeeze the capsule. The beneficial effects of this invention are as follows: Driving the rotary handle to rotate can drive the transmission assembly to pull the brake disc away from the friction pads, thus manually releasing the brake; pressing the first end of the lever can drive its second end to lift the rotary handle, at which point the lever will also pull the brake disc away from the friction pads, thus manually releasing the brake. Compared with the prior art, this invention has two manual release methods: driving the rotary handle to rotate left and right, and pressing the first end of the lever to move it back and forth. The pressing-the-lever method is more suitable for temporary brake release, meeting various usage needs of the brake. Attached Figure Description

[0017] The technical solution of this utility model will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0018] See Figures 1 to 4 A multi-directional manually released brake includes a brake body 1, which may include a housing, a rotor rotatably disposed within the housing, and an axially movable brake disc. The brake disc is typically an armature. An electromagnet disposed within the housing is usually used to apply electromagnetic force to the armature, thereby driving the armature to press against or disengage from the friction pads of the rotor to achieve braking and releasing of the brake.

[0019] As described in Chinese Patent No. CN220101873U, a rotating handle 2 is rotatably mounted on the end face of the housing, and a transmission assembly 3 is adapted between the rotating handle 2 and the brake body 1. A pull rod 4 is also connected between the rotating handle 2 and the brake disc. After the rotating handle 2 is rotated, the rotating handle 2 will move axially under the drive of the transmission assembly 3, thereby driving the pull rod 4 to pull the brake disc away from the friction pad, thus realizing the manual release of the brake.

[0020] What's particularly different is that a lever handle 5 is also provided between the end face of the rotary handle 2 and the housing, and a support point 6 is adapted to form between the lever handle 5 and the housing. When the first end 7 of the lever handle 5 is pressed, the second end 8 of the lever handle 5 will deflect around the support point 6, ultimately causing the second end 8 of the lever handle 5 to push the rotary handle 2 to make the same axial movement as described above. At this time, the pull rod 4 will also pull the brake disc to disengage from the friction pad to achieve manual release of the brake.

[0021] In some embodiments, a spring 11 may be provided on the end face of the housing. The spring 11 pulls the end face of the rotary handle 2, thereby causing the rotary handle 2 to tend to stay close to the housing, thus maintaining the tight braking of the brake disc and the friction plate. For example, a connecting post 13 may also be provided on the end face of the housing, and the spring 11 is sleeved on the outside of the connecting post 13. The connecting post 13 guides the direction of the force applied by the spring 11, making the movement of the rotary handle 2 more stable and reliable.

[0022] The rotating handle 2 may include a pushing part 15, a supporting part 16 and a pressing part 17 in sequence. The supporting part 16 may be a bent structure, thereby forming the aforementioned support point 6 at the bend of the supporting part 16. The pushing part 15 may be disc-shaped, and a connecting hole 12 for the spring 11 to pass through may be provided on the pushing part 15.

[0023] In a specific example, the transmission component 3 may include a transmission pin 9 disposed on the end face of the housing, and a corresponding drive groove 10 may be provided on the end face of the rotating handle 2. The drive groove 10 can be found in the drive groove of Chinese Patent No. CN220101873U, for example, the drive groove 10 extends in an arc shape and the depth gradually decreases, and the end of the transmission pin 9 is inserted into the drive groove 10.

[0024] When the rotary handle 2 is rotated, the transmission pin 9 changes its relative position in the drive groove 10 in the circumferential direction. Since the groove depth of the drive groove 10 changes in the circumferential direction, the transmission pin 9 and the drive groove 10 cooperate to push the rotary handle 2 to move axially.

[0025] For example, the transmission pins 9 and the drive grooves 10 can be arranged in groups along the circumference to ensure the stability of the rotary handle 2 during rotation and axial movement.

[0026] A pin hole 14 is provided through the part of the bent portion of the lever 5 that fits against the end face of the housing. A transmission pin 9 is adapted to pass through the pin hole 14, thereby providing a connection point between the lever 5 and the housing without the need for other connecting mechanisms to connect the lever 5 to the housing.

[0027] In some embodiments, the transmission pin 9 has a cavity 18, and a through hole 19 communicating with the cavity 18 is provided on the top surface of the transmission pin 9, and a groove 23 communicating with the cavity 18 is provided on the side wall of the transmission pin 9. A bladder 20 storing lubricating oil is provided inside the cavity 18, and the liquid outlet of the bladder 20 extends into the through hole 19.

[0028] Furthermore, a compression plate 22 is slidably disposed below the bladder 20 within the cavity 18, and a push rod 24 extending from the groove 23 is disposed on the side wall of the compression plate 22. A protrusion 25 is disposed on the side wall of the lever 5 corresponding to the push rod 24. It can be imagined that when the lever 5 is deflected, the protrusion 25 can push the push rod 24, thereby driving the compression plate 22 to compress the bladder 20, allowing lubricating oil to flow into the through hole 19. The lubricating oil in the through hole 19 can lubricate the frictional sliding between the transmission pin 9 and the drive groove 10, making the rotation of the rotating handle 2 smoother and more stable.

[0029] For example, a sponge 21 can be placed inside the through hole 19 to absorb the lubricating oil filled in, so that the lubricating oil is less likely to flow out from the through hole 19.

[0030] The above description is merely a preferred embodiment of this utility model. It should be understood that this utility model is not limited to the forms disclosed herein and should not be construed as excluding other embodiments. It can be used in various other combinations, modifications, and environments, and can be altered within the scope of the concept described herein through the above teachings or related technologies or knowledge. Modifications and variations made by those skilled in the art that do not depart from the spirit and scope of this utility model should be protected within the scope of the appended claims.
