Description

Technical Field

[0001] This application belongs to the field of mechanical braking technology, and specifically relates to a brake. Background Technology

[0002] Existing brakes include various structural types. One type of brake includes a housing, coil, armature, friction disc, tailplate, assemblies, and manual release assembly. This allows for manual release of the brake during power outages, for inspection, maintenance, and repositioning. The manual release assembly specifically includes a handle, ball bearings, a release pin, an elastic element, and a positioning pin. The ball bearings are located between the handle and the housing. The release pin passes through the housing along its axis and cooperates with the elastic element, abutting against the armature. The handle is fixedly connected to the release pin via the positioning pin. Rotating the handle moves the ball bearings outside the handle's groove, lifting the handle and causing the release pin to move away from the armature, allowing the friction disc to rotate freely.

[0003] However, the method of fixing the handle to the release pin via the positioning pin requires drilling a threaded hole in the release pin and matching the size of the positioning pin. Utility Model Content

[0004] The purpose of this application is to provide a brake that solves the technical problem in the prior art where the handle is fixedly connected to the release pin by a positioning pin, requiring a threaded hole to be made on the release pin and the size of the positioning pin to match.

[0005] To achieve the above objectives, the technical solution adopted in this application is as follows: This application provides a brake, comprising: a housing; an armature disposed adjacent to the housing; a friction disc disposed adjacent to the armature; a tailplate disposed adjacent to the friction disc and connected to the housing via an assembly; a coil disposed within the housing and facing the armature; and a manual release assembly disposed at the end of the housing away from the armature, comprising a handle, a ball, an elastic element, and a release pin; wherein the housing has a first limiting groove, the handle has a second limiting groove, the ball is disposed within the first limiting groove, and has a position within the first limiting groove. The first posture within the second limiting groove and the second posture outside the second limiting groove; the elastic element is disposed within the housing, the release post penetrates the housing and has a first limiting step that abuts against the elastic element; the handle is sleeved on the outer periphery of the release post, and the end of the release post away from the armature has a first riveting part. Before installation, the first riveting part can pass through the first central hole of the handle and protrude from the handle. After installation, the first riveting part deforms and abuts against the end of the handle away from the housing. When the coil is energized, it generates a magnetic field, causing the armature to move towards the housing against the elastic force of the elastic element. When the coil is not energized and the handle is not rotated, the ball is located in the second limiting groove, the elastic element is in close contact with the first limiting step, the first limiting step abuts against the armature, and the armature presses against the friction disc. When the handle is rotated, the ball is located outside the second limiting groove, the handle is lifted by the ball, the handle moves the release post away from the armature, the elastic element is squeezed by the first limiting step, and the friction disc is released.

[0006] In some possible implementations, the release post has a second limiting step that forms a third limiting groove together with the first riveting portion, and the handle abuts against the second limiting step in the axial direction.

[0007] In some possible implementations, the part of the handle that contacts the first riveting part has a plurality of first notches, and the first riveting part is embedded in the plurality of first notches.

[0008] In some possible implementations, the release post has a hollow structure, and the first central hole has a first chamfer on the edge of the hole wall near the first riveting part.

[0009] In some possible implementations, the release post has a columnar body, the first limiting step is an annular body fitted onto the columnar body, and the other end of the columnar body away from the first riveting part has a second riveting part that abuts against the first limiting step.

[0010] In some possible implementations, the portion where the first limiting step contacts the second riveting part has several second notches, and the second riveting part is embedded in several second notches.

[0011] In some possible implementations, the first limiting step has a second central hole fitted onto the columnar body, and the second central hole has a second chamfer on the edge of the hole wall near the second riveting part.

[0012] In some possible implementations, a gasket is provided between the elastic element and the first limiting step.

[0013] In some possible implementations, the outer periphery of the housing is provided with a first mounting lug, the outer periphery of the armature is provided with a second mounting lug, the outer periphery of the tailplate is provided with a third mounting lug, and the fitting is connected between the first mounting lug and the third mounting lug, and slides through the second mounting lug.

[0014] In some possible implementations, the tailplate has mounting ears on its outer periphery, and the brake further includes a mounting member connected to the mounting ears, the mounting member being configured to be fixedly connected to the target device.

[0015] The brake provided in this application has at least the following technical advantages compared with the prior art: When the handle is not rotated, the ball is located in the second limiting groove, the elastic element is in close contact with the first limiting step, the first limiting step abuts against the armature, and the armature presses against the friction disc, at which time the friction disc cannot rotate freely; when the handle is rotated, the ball is located outside the second limiting groove, the handle is lifted by the ball, the handle drives the release column away from the armature, the elastic element is squeezed by the first limiting step, the friction disc is released, and at this time the friction disc can rotate freely. This manual release method is simpler to operate, and the elastic element retains the traditional function of pushing the armature, and can also be driven by the release column to achieve the effect of manual release.

[0016] Furthermore, existing methods typically use connectors such as positioning pins for fixed connection between the handle and the release pin, which not only requires matching the size of the positioning pins but also necessitates drilling threaded holes in the handle, making the installation process and manufacturing steps more complex. In contrast, the brake provided in this application embodiment has a handle fitted around the outer periphery of the release pin. The release pin has a first riveting part, which, after deformation, abuts against the end of the handle away from the housing. The handle is installed primarily using the structural design of the release pin itself, eliminating the need for threaded holes in the handle and positioning pins, thus simplifying the installation process and manufacturing steps.

[0020] To make the technical problems, technical solutions, and beneficial effects to be solved by this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and are not intended to limit the scope of this application.

[0021] It should be noted that when an element is referred to as "fixed to," "fixed," "connected to," "connected to," "set on," "set on," or "fixed to" another element, an intervening element may or may not be present. Furthermore, when an element is referred to as "connected to" or "connected to" another element, it can be interpreted, according to the conventional understanding of those skilled in the art, as a mechanical connection, electrical connection, communication connection, etc. In this document, "multiple" refers to two or more items; "several" refers to one or more items.

[0022] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains.

[0023] Please refer to the following: Figures 1 to 9 The brake provided in the embodiments of this application will now be described.

[0024] Please see Figures 1 to 6 This application provides a brake 1, including: a housing 10; an armature 20, disposed adjacent to the housing 10; a friction disc 30, disposed adjacent to the armature 20; a tail plate 40, disposed adjacent to the friction disc 30 and connected to the housing 10 via an assembly 80; a coil 50, disposed inside the housing 10 and facing the armature 20; and a manual release assembly 60, disposed at the end of the housing 10 away from the armature 20, including a handle 61, a ball 62, an elastic element 63, and a release post 64; wherein the housing 10 has a first limiting groove 11, the handle 61 has a second limiting groove 611, and the ball 62 is disposed in the first limiting groove 11. The release post 64 is disposed within the housing 10 and has a first posture located within the second limiting groove 611 and a second posture located outside the second limiting groove 611. The elastic member 63 is disposed within the housing 10, and the release post 64 is disposed through the housing 10 and has a first limiting step 641 that abuts against the elastic member 63. The handle 61 is sleeved on the outer periphery of the release post 64. The end of the release post 64 away from the armature 20 has a first riveting part 642. Before installation, the first riveting part 642 can pass through the first central hole 612 of the handle 61 and protrude from the handle 61. After installation, the first riveting part 642 deforms and abuts against the end of the handle 61 away from the housing 10.

[0025] The ball bearing 62 is always located within the first limiting groove 11. The handle 61 can drive the release pin 64 to axially compress the elastic element 63. When the coil 50 is energized, it generates a magnetic field, causing the armature 20 to overcome the elastic force of the elastic element 63 and move towards the housing 10. When the coil 50 is not energized and the handle 61 is not started to rotate, the ball bearing 62 is located within the second limiting groove 611, the elastic element 63 is in close contact with the first limiting step 641, the first limiting step 641 abuts against the armature 20, and the armature 20 presses against the friction disc 30. At this time, the friction disc 30 cannot rotate freely. When the handle 61 starts to rotate, the ball bearing 62 is located outside the second limiting groove 611, the handle 61 is lifted by the ball bearing 62, the handle 61 drives the release pin 64 away from the armature 20, the elastic element 63 is compressed by the first limiting step 641, the friction disc 30 is released, and at this time the friction disc 30 can rotate freely.

[0026] It is understood that the number of coil 50, elastic element 63, ball 62, first limiting groove 11 and second limiting groove 611 can all be one or more, and there is no specific limitation on this. The positional relationship between release post 64 and elastic element 63 can be arranged in various ways. For example, release post 64 passes through the central hole of housing 10, and elastic element 63 is provided and sleeved on the outer periphery of release post 64. One end of elastic element 63 abuts against the first limiting step 641, and the other end abuts against the stepped abutment portion formed by the central hole of housing 10. As another example, there are multiple elastic elements 63. Release post 64 passes through the central hole of housing 10, and housing 10 is provided with multiple blind holes around the circumference of release post 64. One elastic element 63 is provided in each blind hole. One end of elastic element 63 abuts against the first limiting step 641, and the other end abuts against the blind end abutment portion of the blind hole. Of course, in other embodiments, while multiple elastic elements 63 can be provided on the housing 10, an elastic element 63 can also be sleeved on the outer periphery of the release post 64, without any specific limitation.

[0027] The brake 1 provided in this application embodiment has at least the following technical effects compared with the prior art: When the handle 61 is not started to rotate, the ball 62 is located in the second limiting groove 611, the elastic member 63 is in close contact with the first limiting step 641, the first limiting step 641 abuts against the armature 20, and the armature 20 presses the friction disc 30. At this time, the friction disc 30 cannot rotate freely. When the handle 61 is started to rotate, the ball 62 is located outside the second limiting groove 611, the handle 61 is lifted by the ball 62, the handle 61 drives the release column 64 away from the armature 20, the elastic member 63 is squeezed by the first limiting step 641, and the friction disc 30 is released. At this time, the friction disc 30 can rotate freely. This manual release method is simpler to operate, and the elastic member 63 retains the traditional function of pushing the armature 20, and can also be driven by the release column 64 to achieve the effect of manual release.

[0028] Furthermore, existing methods typically use connectors such as positioning pins to fix the handle 61 and release pin 64 together. This not only requires matching the size of the positioning pins but also requires threaded holes to be made in the handle 61, making the installation process and manufacturing steps more complex. In contrast, in the brake 1 provided in this application embodiment, the handle 61 is sleeved on the outer periphery of the release pin 64. The release pin 64 has a first riveting part 642, which, after deformation, abuts against the end of the handle 61 away from the housing 10. The installation of the handle 61 is achieved mainly by utilizing the structural design of the release pin 64 itself, eliminating the need for threaded holes in the handle 61 and positioning pins, thus simplifying the installation process and manufacturing steps.

[0029] And, as Figure 8 As shown, the release column 64 can be a solid structure, such as... Figure 7 As shown, the release post 64 can also be a hollow structure. When the release post 64 adopts a hollow structure, the overall weight of the brake 1 can be reduced, and the motor shaft can also pass through the brake 1 through the hollow structure, thereby increasing the application range of the brake 1.

[0030] The specific structure of the manual release component 60 is illustrated below, but it is not limited to the following embodiments.

[0031] Please see Figures 1 to 6 In some embodiments, the release post 64 has a second limiting step 644 that forms a third limiting groove 643 together with the first riveting portion 642, and the handle 61 abuts against the second limiting step 644 in the axial direction. In this embodiment, the second limiting step 644 is used to limit the handle 61 from facing the handle surface of the housing 10, and the first riveting portion 642 is used to limit the handle 61 from facing away from the handle surface of the housing 10.

[0032] The first riveting part 642 is integrally formed from the release post 64. When the handle 61 is not installed, the outer diameter of the first riveting part 642 is smaller than the outer diameter of the central hole of the handle 61. When installing the handle 61, the handle 61 is first fitted onto the outer circumference of the release post 64. At this time, the height of the portion of the release post 64 protruding from the handle 61 can be 1 mm to 2 mm. The riveting equipment applies pressure to the first riveting part 642 before deformation, causing the first riveting part 642 to deform, thereby tightening with the first central hole 612 of the handle 61. At the same time, the height of the portion of the first riveting part 642 protruding from the handle 61 decreases, and the cross-section of the portion of the first riveting part 642 protruding from the handle 61 increases. This cross-section is larger than the size of the first central hole 612 of the handle 61, thus realizing the riveting of the handle 61 and the release post 64. The installation process is simple and convenient. The above riveting method can be spin riveting, cold heading, cold pressing, drilling riveting, etc., without specific limitations.

[0033] Please see Figure 7 and Figure 8In some embodiments, the part of the handle 61 that contacts the first riveting part 642 has several first notches 613, and the first riveting part 642 is embedded in the several first notches 613. Specifically, the handle 61 may be provided with one or more first notches 613. During the riveting process, the first riveting part 642 deforms and fills into the first notches 613, so that the first riveting part 642 is embedded in the first notches 613. This can prevent relative rotation between the handle 61 and the release post 64 and ensure the installation reliability of the handle 61.

[0034] Please see Figure 7 The release post 64 has a hollow structure, and the first central hole 612 has a first chamfer 614 near the edge of the hole wall of the first riveting part 642. In this embodiment, the handle 61 is sleeved on the outer periphery of the release post 64 through the central hole, that is, the first central hole 612. The first chamfer 614 can be an angled corner or a rounded corner, which can increase the contact area between the handle 61 and the first riveting part 642, and facilitate the deformation of the first riveting part 642 during the riveting process, reducing the physical obstruction of the first riveting part 642 during the riveting process.

[0035] Of course, in other embodiments, the first chamfer 614 may not be provided on the wall of the first central hole 612, and there are no specific restrictions on this.

[0036] Please see Figures 9 to 11 In some embodiments, the release post 64 has a columnar body, and the first limiting step 641 is an annular body fitted onto the columnar body. The other end of the columnar body, away from the first riveting portion 642, has a second riveting portion 645 that abuts against the first limiting step 641. In this embodiment, the release post 64 is actually composed of a columnar body and an annular body, which are connected together by riveting. The first limiting step 641 is fitted onto the outer periphery of the columnar body, and the second riveting portion 645 locks the first limiting step 641. The riveting process of the first limiting step 641 is the same as the riveting process of the handle 61 described above, and will not be repeated here.

[0037] Understandably, the cylindrical body can be hollow or solid. The outer diameters at both ends of the cylindrical body can be the same or different. When the outer diameters at both ends of the cylindrical body are the same, rivet joints of the same size can be used. The release column 64 adopts a split structure, which can reduce raw material costs and processing volume, thereby reducing the overall production cost of the brake 1.

[0038] Of course, in other embodiments, the release post 64 can be an integral structure, that is, the first limiting step 641 and the columnar body of the release post 64 are formed as one piece.

[0039] Please see Figure 11In some embodiments, a plurality of second notches 6411 are provided at the contact points between the first limiting step 641 and the second riveting part 645, and the second riveting part 645 is embedded in the plurality of second notches 6411. Specifically, the first limiting step 641 may be provided with one or more second notches 6411. During the riveting process, the second riveting part 645 deforms and fills into the second notches 6411, ultimately making the second riveting part 645 embedded in the second notches 6411. This can prevent relative rotation between the first limiting step 641 and the columnar body, ensuring the installation reliability of the first limiting step 641.

[0040] Please see Figure 11 In some embodiments, the first limiting step 641 has a second central hole fitted onto the cylindrical body, and a second chamfer 6412 is provided on the edge of the hole wall near the second riveting part 645. The first limiting step 641 is fitted onto the outer periphery of the cylindrical body through the second central hole. The second chamfer 6412 can be an angled angle or a rounded corner, which can increase the contact area between the second riveting part 645 and the first limiting step 641, and facilitate the deformation of the second riveting part 645 during the riveting process, reducing physical obstruction during the riveting process.

[0041] Of course, in other embodiments, the first limiting step 641 may not have the second chamfer 6412, and there are no specific restrictions on this.

[0042] In some embodiments, a shim is provided between the elastic member 63 and the first limiting step 641. By providing the shim, the adverse effects of the release post 64 on the elastic member 63 during rotation can be reduced, extending the service life of the elastic member 63. In addition, a lubricating coating can be provided on one end face of the shim facing the first limiting step 641, or a lubricating coating can be provided on both end faces of the shim, which can make the rotation process of the release post 64 smoother.

[0043] Please see Figure 1 and Figure 2 In some embodiments, the handle 61 has a strip-shaped limiting hole 615, and the manual release assembly 60 also includes a limiting post 65. The limiting post 65 is connected to the housing 10 and extends out of the limiting hole 615, and can abut against the limiting hole 615 when the handle 61 is rotated. In this embodiment, the limiting post 65 is used to limit the rotation angle of the handle 61. The limiting hole 615 is a strip-shaped elongated hole. Since the limiting post 65 is connected to the housing 10 to maintain a stationary posture, when the handle 61 is rotated to the target angle, the limiting post 65 abuts against one end of the limiting hole 615, so that the handle 61 can no longer rotate.

[0044] To improve the versatility of parts, such as Figure 2As shown, for example, the housing 10 has a first positioning hole 12 and a second positioning hole 13, and a limiting post 65 is selectively disposed in either the first positioning hole 12 or the second positioning hole 13. The first positioning hole 12 and the second positioning hole 13 correspond to the two ends of the strip-shaped limiting hole 615, respectively. When it is necessary to rotate the handle 61 clockwise to limit the rotation angle, the limiting post 65 is disposed in the second positioning hole 13; when it is necessary to rotate the handle 61 counterclockwise to limit the rotation angle, the limiting post 65 is disposed in the first positioning hole 12, so as to adapt to installation environments with more rotation methods.

[0045] Of course, in other embodiments, the housing 10 may be provided with only one positioning hole, which is suitable for installation environments where the handle 61 is triggered by rotation in one direction.

[0046] Please see Figure 1 and Figure 2 In some embodiments, the brake 1 further includes a micro switch 70 disposed on the outer periphery of the housing 10. The micro switch 70 is connected in series with the coil 50, or in parallel with the coil 50, or configured to be connected to the controller. The handle 61 can trigger the micro switch 70 during rotation. By setting the micro switch 70, the handle 61 can transmit a state signal indicating that the friction disc 30 is released or pressed when rotated. As mentioned above, the handle 61 can be rotated clockwise to trigger the micro switch 70, or it can be rotated counterclockwise. The direction of rotation and the position of the limiting post 65 mainly depend on the set triggering method.

[0047] Specifically, the micro switch 70 can be connected in series with the coil 50, in which case the micro switch 70 can control the energization and de-energization of the coil 50; the micro switch 70 can also be connected in parallel with the coil 50, in which case the micro switch 70 can adjust the current signal of the coil 50; the micro switch 70 can also be connected to the controller instead of the coil 50, and after being triggered by the handle 61, it can provide the controller with a signal of the current posture of the handle 61, so that the controller can determine and control the opening and closing of the micro switch 70.

[0048] It is understandable that the handle 61 can be configured to indicate that the friction disc 30 is in a released state when the micro switch 70 is triggered, and that the friction disc 30 is in a pressed state when the handle 61 is removed from the micro switch 70; alternatively, the handle 61 can be configured to indicate that the friction disc 30 is in a pressed state when the micro switch 70 is triggered, and that the friction disc 30 is in a released state when the handle 61 is removed from the micro switch 70. The triggering method depends primarily on the initial position of the handle 61.

[0049] In this embodiment, a small-sized micro switch 70 can be used. The fixing holes of the micro switch 70 are spaced relatively close together. The micro switch 70 is aligned with the handle 61, and the two screws used to fix the micro switch 70 are located on the same distribution circle.

[0050] Please see Figure 1 , Figures 12 to 14 In some embodiments, the outer periphery of the housing 10 is provided with a first mounting lug 14, the outer periphery of the armature 20 is provided with a second mounting lug 21, and the outer periphery of the tailplate 40 is provided with a third mounting lug 41. The fitting 80 is connected between the first mounting lug 14 and the third mounting lug 41 and is slidably disposed through the second mounting lug 21. In this embodiment, the armature 20 needs to be movable in the axial direction; therefore, the fitting 80 and the second mounting lug 21 are slidably disposed.

[0051] Mounting holes are provided on the first mounting ear 14, the second mounting ear 21, and the third mounting ear 41. The mounting parts 80 are sequentially disposed in these mounting holes. It can be understood that these mounting holes can be closed structures or structures with circumferential notches. The coil 50 divides the end face of the housing 10 facing the armature 20 into an inner magnetic pole surface 15 and an outer magnetic pole surface 16. The mounting parts 80 are disposed on the outer side of the outer magnetic pole surface 16 of the housing 10, which reduces the number of openings on the outer magnetic pole surface 16, thereby allowing for a smaller radial thickness of the outer magnetic pole surface 16, less material to be used, and a lighter weight for the housing 10. The outer diameter of the friction disc 30 can be greater than or equal to the outer diameter of the housing 10, ensuring that, under the same torque, the outer diameter of the brake 1 is smaller and the overall weight is lighter.

[0052] Of course, in other embodiments, based on the above-described adaptation method of the handle 61 and the release post 64, the installation position and method of the accessory 80 can adopt the traditional drilling position and method. For example, the accessory 80 is set on the inner magnetic pole surface 15 or the outer magnetic pole surface 16, and holes are drilled in the housing 10, armature 20 and tail plate 40, etc., without specific restrictions.

[0053] Please see Figure 1 and Figure 14 In some embodiments, the tailplate 40 has a mounting ear 42 on its outer periphery, and the brake 1 further includes a mounting member 90 connected to the mounting ear 42, the mounting member 90 being configured to be fixedly connected to the target device 2. In this embodiment, the mounting ear 42 has a mounting hole, through which the mounting member 90 is locked onto the mounting surface of the target device 2. It is understood that the mounting hole can be a closed hole structure or a hole structure with a circumferential notch.

[0054] Of course, in other embodiments, based on the above-described adaptation method of the handle 61 and the release post 64, the installation position and method of the mounting component 90 can adopt the traditional drilling position and method. For example, the mounting component 90 is set on the inner magnetic pole surface 15 or the outer magnetic pole surface 16, and holes are drilled in the housing 10, armature 20 and tail plate 40, etc., without specific restrictions.

[0055] It is understood that the parts in the above embodiments can be freely combined or deleted to form different combined embodiments.
