Description

Technical Field

[0001] This utility model relates to massage chair accessories, specifically a detachable damped hand controller bracket and its hand controller bracket damping structure. Background Technology

[0002] The controller bracket rotation mechanism of a massage chair is a key component for enhancing the user experience. It allows the controller to be positioned in various ways by rotating, making it convenient for users of different body types to operate. It can also be rotated away from the user to reduce interference with the user's activities.

[0003] To ensure greater stability after rotation, a damping structure is typically used to provide resistance to the rotation.

[0004] A utility model patent (CN210204073U) discloses a massage chair controller bracket rotation mechanism. In this design, the damping structure connector and outer cover are actually part of the massage chair armrest base. This means the damping component is installed inside the armrest base. If the damping component needs maintenance due to aging, the support rod and outer cover must be removed to access the internal damping component, which is inconvenient. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a disassembly damping hand controller bracket and its hand controller bracket damping structure, which can facilitate maintenance and make installation more convenient.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a hand controller bracket damping structure, including a screw cap and a bracket rod. The bracket rod is installed in a massage chair through the screw cap, and the bracket rod passes through the screw cap, forming a rotatable fit with the screw cap. A first damping element, a second damping element, and a clamping element are also connected to the bracket rod. The clamping element is installed on the bracket rod and is used to clamp the first and second damping elements together. The first damping element is circumferentially fixed to the bracket rod and rotates with the bracket rod. The second damping element's circumferential rotation is restricted by a limiting element. When the bracket rod rotates, it drives the first damping element to rotate, and it cooperates with the second damping element to form damping. The limiting element is fixedly connected to the massage chair.

[0007] As a further improvement of this utility model, a limiting step is provided on the bracket rod at the position corresponding to the first damping member. The limiting step cooperates with the tightening member to press the first damping member and the second damping member.

[0008] As a further improvement of this utility model, the limiting step and the first damping member form a keyway fit, so that the bracket rod can drive the first damping member to rotate circumferentially.

[0009] As a further improvement of this utility model, an elastic element is provided between the second damping element and the clamping element, and the clamping element clamps the first damping element and the second damping element together through the elastic element.

[0010] As a further improvement of this utility model, the first damping component, the second damping component, the elastic component, and the clamping component are all sleeved on the bracket rod.

[0011] As a further improvement of this utility model, a gasket is provided between the first damping member and the second damping member, which is used to eliminate frictional noise between the first damping member and the second damping member.

[0012] As a further improvement of this utility model, the limiting member is provided with a groove, and the second damping member is provided with a protrusion at the position corresponding to the groove. The second damping member restricts the circumferential rotation of the second damping member through the insertion and cooperation of the groove and the protrusion.

[0013] As a further improvement of this utility model, the limiting member is provided with a connecting hole for the insertion of the clamping member. The clamping member is inserted into the connecting hole and forms a rotatable fit with the connecting hole. The connecting hole, in conjunction with the clamping member, restricts the swing of the bracket rod.

[0014] As a further improvement of this utility model, the outer wall of the clamping member is provided with a plurality of protruding rings that extend circumferentially along the outer wall of the clamping member and are connected end to end. The protruding rings are used to cooperate with the inner wall of the connecting hole to form a rotational fit.

[0015] A detachable damped hand controller bracket includes a bracket body 9 and a hand controller bracket damping structure as described in any of the above improvements. The bracket body 9 is fixedly connected to a bracket rod. A limiting step is also provided on the cover, the position of which corresponds to the position of the first damping element. When the cover is connected to the massage chair, the limiting step restricts the first damping element, the second damping element, the clamping element, and the bracket rod from disengaging from the cover.

[0016] The advantages of this invention are that it is convenient to disassemble and maintain, and simple to install; the rotation angle of the bracket rod is not restricted, making it more flexible to use. Attached Figure Description

[0026] The present invention will now be described in further detail with reference to the embodiments shown in the accompanying drawings.

[0027] Reference Figure 1-8 As shown,

[0028] A hand controller bracket damping structure includes a screw cap 1 and a bracket rod 2. The bracket rod 2 is installed in a massage chair (which can be the armrest of the massage chair) through the screw cap 1. The bracket rod 2 passes through the screw cap 1 and forms a rotatable engagement with the screw cap 1. A first damping element 3, a second damping element 4, and a clamping element 5 are also connected to the bracket rod 2. The clamping element 5 is installed on the bracket rod 2 and is used to clamp the first damping element 3 and the second damping element 4. The first damping element 3 is circumferentially fixed to the bracket rod 2 and rotates with the bracket rod 2. The second damping element 4 is restricted from circumferential rotation by a limiting element 6. When the bracket rod 2 rotates, it drives the first damping element 3 to rotate and cooperates with the second damping element 4 to form damping. The limiting element 6 is fixedly connected to the massage chair.

[0029] When the bracket rod 2 rotates, the first damping element 3 rotates synchronously with it, while the second damping element 4 remains stationary due to the fixing effect of the limiting element 6. The contact surface between the two generates damping friction, thereby controlling the rotation speed of the bracket rod 2 and maintaining its stable position. This design generates damping solely through the friction between the two damping elements, allowing the bracket rod 2 to rotate 360° without obstruction. The clamping element 5 can adjust the clamping force between the first damping element 3 and the second damping element 4 via axial pressure, thus adjusting the damping magnitude. The fixed connection between the limiting element 6 and the massage chair ensures that the second damping element 4 cannot rotate circumferentially. The limiting element 6 can be fixed to the massage chair with screws or clips, ensuring reliable connection.

[0030] The aforementioned first damping component 3, second damping component 4, clamping component 5, and bracket rod 2 can be installed on the massage chair in conjunction with the rotating cover 1, as can be referred to. Figure 2 and 3 The structure shown can be applied in two ways: the cap 1 can be directly and rotatably snapped onto the clamping member 5, or it can be rotatably snapped onto the bracket body 9 in the figure.

[0031] Based on any of the above installation methods, the first damping component 3, the second damping component 4, and the clamping component 5 in this solution are all installed on the bracket rod 2. Therefore, during disassembly and maintenance, it is only necessary to remove the cap 1 and take out the bracket rod 2 at the same time to remove the first damping component 3, the second damping component 4, and the clamping component 5, which is convenient for maintenance and installation.

[0032] In a further configuration, a limiting step 21 is provided on the bracket rod 2 at the position corresponding to the first damping component 3. This limiting step 21 cooperates with the clamping component 5 to press the first damping component 3 and the second damping component 4.

[0033] The limiting step 21 provides axial support for the clamping member 5. The clamping member 5 is connected to the bracket rod 2 by threads or elastic clips (or fasteners can be used for connection, such as...). Figure 3 and 6 As shown, by pre-drilling a threaded hole at the bottom of the bracket rod 2 and connecting the fastener to the threaded hole, the clamping member 5 is installed on the bracket rod 2, pressing the first damping member 3 and the second damping member 4 to ensure uniform transmission of damping force. The limiting step 21 further restricts the axial displacement of the first damping member 3 on the bracket rod 2, preventing the damping member from loosening due to long-term use.

[0034] To make the fit between the bracket rod 2 and the first damping element 3 more stable, a keyway fit is formed between the limiting step 21 and the first damping element 3, so that the bracket rod 2 can drive the first damping element 3 to rotate circumferentially.

[0035] The keyway, in conjunction with the support rod 2, transmits the rotational force of the bracket rod 2 to the first damping element 3, eliminating relative slippage between them and ensuring stable damping force. This structure also simplifies the installation process and enables rapid positioning through the guiding effect of the keyway.

[0036] The keyway fit in this solution can be referenced. Figure 8 As shown, the key is located on the first damping member 3 and is integrally formed with it, while the groove is located on the bracket rod 2. Specifically, the bracket rod 2 has a cylindrical structure with notches on its side forming a groove. The position of the corresponding notch on the first damping member 3 can be filled when the two are connected, and the filling part is the key. Of course, there can be multiple notches and multiple keys.

[0037] In a further configuration, a spring element 7 is provided between the second damping element 4 and the clamping element 5, and the clamping element 5 clamps the first damping element 3 and the second damping element 4 together through the spring element 7.

[0038] The elastic element 7 provides a continuous elastic preload to compensate for the gaps caused by wear of the damping element and maintain the damping force. The compression of the elastic element 7 can be steplessly adjusted by adjusting the position of the clamping element 5 to adapt to different working conditions.

[0039] Elastic component 7 can be referenced. Figure 2 , 3 As shown in Figure 6, it is composed of two annular pads and an annular corrugated elastic pad between the two pads.

[0040] As an optional solution to further facilitate installation, the first damping component 3, the second damping component 4, the elastic component 7, and the clamping component 5 are all fitted onto the bracket rod 2.

[0041] All components are arranged along the axis of bracket rod 2, resulting in a compact structure and controllable axial dimensions. The sleeve design simplifies the assembly process, with the elastic element 7 restrained between bracket rod 2 and clamping element 5 to prevent displacement or detachment. It also allows for easy disassembly and direct exposure of all damping components, improving maintenance efficiency.

[0042] Optionally, a shim 8 is provided between the first damping member 3 and the second damping member 4, which is used to eliminate frictional noise between the first damping member 3 and the second damping member 4.

[0043] The gasket 8 is made of polytetrafluoroethylene, nylon, or rubber to eliminate frictional noise between the first damping element 3 and the second damping element 4. The gasket 8 also distributes pressure evenly, preventing localized stress concentration that could lead to deformation or uneven wear of the damping elements. The first damping element 3 and the second damping element 4 can be made of plastic, polytetrafluoroethylene, or nylon. When the first damping element 3 and the second damping element 4 are made of the same material and rub against each other, frictional noise is likely to occur. This solution uses the gasket 8 to eliminate this frictional noise.

[0044] This solution is only an optional solution, and the implementation of this solution will not be affected even without the gasket 8.

[0045] As an optional solution, the limiting member 6 is provided with a groove 61, and the second damping member 4 is provided with a protrusion 41 at the position corresponding to the groove 61. The second damping member 4 restricts the circumferential rotation of the second damping member 4 through the interlocking of the groove 61 and the protrusion 41.

[0046] The insertion and engagement of the groove 61 and the protrusion 41 form a mechanical lock, ensuring that the second damping member 4 remains stationary. Moreover, this engagement is convenient for installation, as the limiting member 6 is located on the massage chair, and the insertion and engagement of the protrusion 41 and the groove 61 can be completed during the process of installing the bracket rod 2 onto the massage chair.

[0047] In a further configuration, the limiting member 6 is provided with a connecting hole 62 for the insertion of the clamping member 5. The clamping member 5 is inserted into the connecting hole 62 and forms a rotatable fit with the connecting hole 62. The connecting hole 62, in conjunction with the clamping member 5, restricts the swing of the bracket rod 2.

[0048] The rotational engagement between the clamping member 5 and the connecting hole 62 allows the bracket rod 2 to rotate freely, while the inner wall of the connecting hole 62 restricts the radial displacement of the clamping member 5.

[0049] Preferably, the outer wall of the clamping member 5 is provided with a plurality of protruding rings 51 extending circumferentially along the outer wall of the clamping member 5 and connected end to end. The protruding rings 51 are used to form a rotational fit with the inner wall of the connecting hole 62.

[0050] The convex ring 51 reduces the contact area between the clamping part 5 and the connecting hole 62, thereby reducing frictional resistance. At the same time, it distributes the load evenly through multi-point contact, thus avoiding localized wear.

[0051] The above mainly introduces the damping structure. Applying it to the bracket can form the following solution: a detachable damping hand controller bracket, including a bracket body 9 and a hand controller bracket damping structure as described in any of the above improvements. The bracket body 9 is fixedly connected to the bracket rod 2. The cover 1 is also provided with a limiting step 2 11. The position of the limiting step 2 11 corresponds to the position of the first damping member 3. When the cover 1 is connected to the massage chair, the limiting step 2 11 restricts the first damping member 3, the second damping member 4, the clamping member 5, and the bracket rod 2 from disengaging from the cover 1.

[0052] The bracket body 9 is fixed to the bracket rod 2 by bolts or clips. In practical applications, the user can rotate the bracket body 9 to rotate the bracket rod 2. The limiting step of the cover 1 is axially aligned with the damping component. After the cover 1 is installed, it forms a mechanical barrier to prevent the bracket rod 2 from moving axially or the damping component from accidentally falling off. During maintenance, only the cover 1 needs to be loosened to remove the bracket rod 2 and the damping component as a whole, without disassembling other parts of the massage chair.

[0053] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
