Description

Technical Field

[0001] The present invention relates to the technical field of brake mechanisms, and in particular to a brake clutch device. Background Art

[0002] Existing brake devices cannot automatically and immediately stop the rotating shaft. In the fields of vehicle operation, elevators, electric wheelchairs, etc., the equipment often cannot stop immediately after the motor stops rotating, resulting in a safety hazard of the equipment continuing to move when the power is lost. In view of this, a new brake clutch device is needed that can automatically stop the equipment when the power is lost. Summary of the Invention

[0003] In order to solve the above technical problems, the present invention proposes a braking clutch device. In the clutch assembly of this technical solution, when the rotating part rotates a certain angle, the cam part rotates, thereby controlling the position of the connecting part, and then the connecting part can squeeze and lock the third rotating disk or achieve pressure-free contact between the connecting part and the third rotating disk.

[0004] Specifically, the present invention discloses a brake clutch device, comprising:

[0005] a first rotating disk, wherein the first rotating disk has a connecting portion for connecting to an external driving device;

[0006] a second rotating disk, wherein the second rotating disk is provided with a circular opening, wherein the axis of the circular opening and the axis of the first rotating disk are located on the same straight line, and the second rotating disk is provided with a receiving opening that is in communication with the circular opening;

[0007] a third rotating disk, the third rotating disk being rotatably disposed in the circular opening;

[0008] a connecting portion, the connecting portion being arranged in the accommodating opening via an elastic member;

[0009] a first fixing post, one end of which is fixed to the first rotating disk, and the other end of which extends into the receiving opening;

[0010] A clutch assembly is used to control the connecting part to squeeze and lock the third rotating disk. The clutch assembly includes a cam part and a rotating part. The cam part is rotatably set on the first fixed column, and the cam part is in contact with the connecting part. The rotating part is rotatably set on the third rotating disk, and one end of the cam part is hingedly set on the rotating part.

[0011] The technical effect of this technical solution is that when the rotating part rotates a certain angle, the cam part rotates, thereby controlling the position of the connecting part, and then the connecting part can squeeze and lock the third rotating disk or achieve pressure-free contact between the connecting part and the third rotating disk.

[0012] Furthermore, the cam portion is a waist-shaped component, and a waist-shaped hole is provided on the cam portion, and the transmission pin on the rotating portion can be slidably arranged in the waist-shaped hole.

[0013] Preferably, an annular groove is provided on a side of the third rotating disk facing away from the first rotating disk, and the rotating part is rotatably arranged in the annular groove. The technical effect of this solution is that it provides a structure for installing the rotating part.

[0014] Preferably, a shaft hole for installing a shaft is provided on the third rotating disk.

[0015] Preferably, the device further comprises an end cap having a mounting slot for rotatably mounting the second rotating disk, an arcuate opening extending through the mounting slot, and an adjustment disk rotatably mounted on the side of the end cap facing away from the first rotating disk. The rotating portion is fixed to the adjustment disk via a connector, and the connector is rotatably disposed in the arcuate opening. In this embodiment, rotating the adjustment disk drives the rotating portion to move synchronously, thereby triggering the rotation of the cam portion, thereby achieving adjustment of the connecting portion.

[0016] Preferably, an annular guide portion is provided on the side of the end cap facing away from the first rotating disk, wherein the annular guide portion is provided with an annular guide channel that is in communication with the arc-shaped opening. The adjustment disk is annular, and the axis of the adjustment disk and the annular guide channel coincide. The technical effect of this solution is that it provides an installation method for the adjustment disk.

[0017] Preferably, a plurality of snap-fit ​​portions are provided on the curved surface of the annular guide channel, and a snap-fitting groove portion is provided on a side of the adjustment disk facing the snap-fitting portions, with the snap-fitting portions and the snap-fitting groove portion being snap-fitted to each other. This is so that after the adjustment disk is rotated to a certain angle, the snap-fitting portions and the snap-fitting groove portion engage to limit the adjustment disk, and the adjustment disk will not rotate unless external force is applied to the adjustment disk.

[0018] Preferably, the buckle portion is a raised block, and the side of the raised block facing the adjustment disk is a curved surface. The technical effect of this solution is that under the action of external force, the raised block can slide into the slot and move out of the slot.

[0019] Preferably, the protruding block is arranged in the receiving groove of the annular guide portion through an elastic portion, which makes it easier for the protruding block to cooperate with the slot, so that the protruding block has a certain range of movement and can effectively extend into and out of the slot.

[0020] Preferably, the width of the accommodating opening gradually increases from the center toward the sides, and the diameter of the connecting portion is greater than the minimum width of the accommodating opening, and less than the maximum width of the accommodating opening. The technical effect of this solution is that the shape of the accommodating opening is designed to facilitate the movement of the connecting portion under the action of the elastic member or the first fixed column, thereby facilitating pressure contact between the connecting portion, the first fixed column, and the third rotating disk, thereby causing the three to rotate.

[0021] Preferably, a connecting portion is provided on each side of the first fixed column within the same receiving opening. The elastic member acts to push the connecting portion toward the first fixed column. Given this structure, it is obvious that whenever the first fixed column moves, one of the connecting portions will always move toward the center, thereby causing the connecting portion, the second rotating disk, and the third rotating disk to move synchronously.

[0022] Preferably, the elastic member is a spring or an elastic sheet.

[0023] Preferably, the number of the elastic members in the same receiving opening is two, and the two elastic members are arranged at both ends of the receiving opening. The effect of this solution is that it is easy to push the connecting portion toward the middle.

[0024] Preferably, the second rotating disk is provided with a receiving hole, and a second fixing post is fixed to the first rotating disk. The second fixing post extends into the receiving hole, and a movable gap is left between the second fixing post and the receiving hole. The technical effect of this solution is that the movable gap between the second fixing post and the receiving hole can limit the movement and displacement of the first fixing post in the receiving opening, thereby effectively limiting the deformation of the elastic member.

[0025] Preferably, an internal gear portion is provided on the side of the first rotating disk facing away from the second rotating disk. The technical effect of this technical solution is that it is convenient for the external motor to drive the first rotating disk to rotate through the external gear.

[0026] Furthermore, a first bearing is provided between the mounting hole of the first rotating disk and the rotating shaft. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0039] The present invention will be further described in detail below with reference to the accompanying drawings.

[0040] like Figures 1 to 9 As shown, one embodiment of the present invention discloses a brake clutch device, comprising:

[0041] a first rotating disk 11 , having a connecting portion 12 for connecting to an external driving device;

[0042] A second rotating disk 13 is provided with a circular opening 14, wherein the axis of the circular opening 14 and the axis of the first rotating disk 11 are located on the same straight line, and the second rotating disk 13 is provided with a receiving opening 15 that penetrates the circular opening 14;

[0043] a third rotating disk 16 rotatably disposed in the circular opening 14 ;

[0044] a connecting portion 17 , the connecting portion 17 being disposed in the accommodating opening 15 via an elastic member 19 ;

[0045] a first fixing post 18 , one end of which is fixed to the first rotating disk 11 , and the other end of which extends into the receiving opening 15 ;

[0046] The clutch assembly is used to control the connecting portion 17 to squeeze and lock the third rotating disk 16. The clutch assembly includes a cam portion 26 and a rotating portion 27. The cam portion 26 is rotatably arranged on the first fixed column 18, and the cam portion 26 is in contact with the connecting portion 17. The rotating portion 27 is rotatably arranged on the third rotating disk 16, and one end of the cam portion 26 is hingedly arranged on the rotating portion 27.

[0047] The technical effect of this technical solution is that when the rotating part 27 rotates a certain angle, Figure 9 As shown, the cam portion 26 rotates at this time, thereby controlling the position of the connecting portion 17 , thereby enabling the connecting portion 17 to squeeze and lock the third rotating disk 16 or achieve pressure-free contact between the connecting portion 17 and the third rotating disk 16 .

[0048] Furthermore, the cam portion 26 is a waist-shaped component, and a waist-shaped hole 37 is provided on the cam portion 26 , and the transmission pin 38 on the rotating portion 27 is slidably disposed in the waist-shaped hole.

[0049] As an implementation of this embodiment, the third rotating disk 16 has an annular groove on its side facing away from the first rotating disk 11, and the rotating portion 27 is rotatably disposed in the annular groove. The technical effect of this solution is that it provides a structure for installing the rotating portion 27.

[0050] As an implementation of this embodiment, a shaft hole for installing the shaft 22 is provided on the third rotating disk 16 .

[0051] As an implementation of this embodiment, an end cap 28 is further included. The end cap 28 has a mounting slot for rotatably mounting the second rotating disk 13. The end cap 28 is provided with an arc-shaped opening 30 that extends through the mounting slot. An adjustment disk 31 is rotatably mounted on the side of the end cap 28 facing away from the first rotating disk 11. The rotating portion 27 is fixed to the adjustment disk 31 via a connecting member 32, and the connecting member 32 is rotatably disposed in the arc-shaped opening 30. In this solution, rotating the adjustment disk 31 can drive the rotating portion 27 to move synchronously, thereby triggering the rotation of the cam portion 26, thereby achieving adjustment of the connecting portion 17.

[0052] As one implementation of this embodiment, an annular guide portion 33 is provided on the side of the end cap 28 facing away from the first rotating disk 11. An annular guide channel 34 is defined within the annular guide portion 33 and extends through the arc-shaped opening 30. The adjustment disk 31 is annular, and the axes of the adjustment disk 31 and the annular guide channel 34 coincide. This solution provides a convenient installation method for the adjustment disk 31.

[0053] As an implementation method of this embodiment, a plurality of latching portions 35 are provided on the curved surface of the annular guide channel 34. A latching groove 36 is provided on a side of the adjustment disk 31 facing the latching portions 35. The latching portions 35 are engaged with the latching groove 36. This is to ensure that when the adjustment disk 31 rotates a certain angle, the latching portions 35 and the latching groove 36 engage, thereby limiting the position of the adjustment disk 31. In the absence of external force on the adjustment disk 31, the adjustment disk 31 will not rotate.

[0054] As an implementation of this embodiment, the buckle portion 35 is a raised block, and the side of the raised block facing the adjustment disk 31 is a curved surface. The technical effect of this solution is that under the action of external force, the raised block is easy to slide into the slot and move out of the slot.

[0055] As an implementation method of this embodiment, the protruding block is arranged in the receiving groove of the annular guide portion 33 through an elastic portion. This makes it easier for the protruding block to cooperate with the card slot, so that the protruding block has a certain range of movement and can effectively extend into and out of the card slot.

[0056] As one implementation of this embodiment, the width of the receiving opening 15 gradually increases from the center toward the sides, and the diameter of the connecting portion 17 is greater than the minimum width of the receiving opening 15, while the diameter of the connecting portion 17 is less than the maximum width of the receiving opening 15. The technical effect of this solution is that the shape of the receiving opening 15 is designed to facilitate the movement of the connecting portion 17 under the action of the elastic member 19 and the first fixing post 18, thereby facilitating pressure contact between the connecting portion 17, the first fixing post 18, and the third rotating disk 16, thereby causing the three to rotate.

[0057] As one implementation of this embodiment, a connecting portion 17 is provided on either side of the first fixed post 18 within the same receiving opening 15. The elastic member 19 serves to push the connecting portion 17 toward the first fixed post 18. Given this structure, it is clear that whenever the first fixed post 18 moves, one of the connecting portions 17 will always move toward the center, thereby causing the connecting portions 17, the second rotating disk 13, and the third rotating disk 16 to move synchronously.

[0058] As an implementation of this embodiment, the elastic member 19 is a spring or an elastic sheet.

[0059] As an implementation of this embodiment, there are two elastic members 19 in the same receiving opening 15, and the two elastic members 19 are arranged at both ends of the receiving opening 15. The effect of this solution is that it is easy to push the connecting portion 17 toward the middle.

[0060] As one implementation of this embodiment, the second rotating disk 13 is provided with a receiving hole 20, and a second fixing post 21 is fixed to the first rotating disk 11. The second fixing post 21 extends into the receiving hole 20, and a movable gap is left between the second fixing post 21 and the receiving hole 20. The technical effect of this solution is that the movable gap between the second fixing post 21 and the receiving hole 20 can limit the movement and displacement of the first fixing post 18 in the receiving opening 15, thereby effectively limiting the deformation of the elastic member 19.

[0061] As an implementation of this embodiment, an internal gear portion is provided on the side of the first rotating disk 11 facing away from the second rotating disk 13. The technical effect of this technical solution is that it is convenient for the external motor to drive the first rotating disk 11 to rotate through the external gear.

[0062] Furthermore, a first bearing 23 is provided between the mounting hole of the first rotating disk 11 and the rotating shaft 22 .

[0063] The working principle of the brake clutch device during power-off braking is as follows: When the adjustment disk 31 is in an active state, that is, there is no engagement between the buckle portion 35 and the slot portion 36. The working principle at this time is as follows:

[0064] In order to facilitate the description of the working principle of the brake clutch device, the present invention is attached with a working principle diagram, namely Figure 4 and Figure 5 In addition, the two connecting portions 17 are subdivided into a first connecting portion 24 and a second connecting portion 25 for easy distinction.

[0065] When the external motor drives the first rotating disk 11 to rotate in the forward direction, the first fixed column 18 rotates accordingly and squeezes the second connecting portion 25, thereby driving the second rotating disk 13 to rotate. Figure 7As shown, the second connecting portion 25 is in an active state at this time; at the same time, the spring pushes the first connecting portion 24 to move toward the first fixed column 18, so that the first connecting portion 24 locks the second rotating disk 13 and the third rotating disk 16, and the third rotating disk 16 rotates synchronously.

[0066] When the external motor suddenly loses power and stops rotating, the first rotating disk 11 and the first fixed column 18 stop moving, and the second rotating disk 13 continues to rotate forward under the action of inertia. Forward rotation is clockwise rotation, but the first fixed column has a counterclockwise relative motion with respect to the second rotating disk 13. At this time, the first fixed column 18 pushes the first connecting portion 24 and makes the first connecting portion 24 active. Figure 8 As shown, at the same time, the spring pushes the second engaging portion 25 toward the first fixing post 18, so that the second engaging portion 25 locks the second rotating disk 13 and the third rotating disk 16, thus achieving the function of self-locking when power is lost.

[0067] In addition, the present invention can also set a reset drive mechanism on the first fixed column 18, and the reset drive mechanism has two output ends that push the first connecting part 24 and the second connecting part 25 respectively. By controlling the reset drive mechanism, the first connecting part 24 and the second connecting part 25 can be both in an active state, thereby realizing the clutch of the present device.

[0068] When the external motor drives the first rotating disk 11 to rotate in the reverse direction, the working principle is similar to that when the first rotating disk 11 rotates in the reverse direction. Those skilled in the art should understand this and will not be described in detail here.

[0069] In the present invention, in the initial state, the first and second connecting portions 24, 25 are not in pressure contact with the third rotating disk 16 due to the action of the first fixing post 18. Therefore, the third rotating disk 16 can drive the rotating shaft 22 to move freely. Once the external drive drives the first rotating disk 11 to rotate, according to the above-mentioned operating principle, the rotating shaft 22 can only follow the external drive and move accordingly.

[0070] When the clutch function is realized, the adjusting disk 31 is rotated by a certain angle, and when the adjusting disk 31 is in a locked state, that is, the buckle portion 35 and the slot portion 36 are engaged, the adjusting disk 31 drives the rotating portion 27 to rotate synchronously by a certain angle, so that the cam portion 26 drives the first connecting portion 24 and the second driving portion 25 to move away from the first fixed column 18 respectively, and the clutch function is realized at this time.

[0071] For those skilled in the art, several variations and improvements can be made without departing from the inventive concept of the present invention, and all of these fall within the scope of protection of the present invention.
