Description

Technical Field

[0001] This invention relates to the field of damping structures, and more specifically to a rotary damping structure with a built-in switch. Background Technology

[0002] There are many types of damping structures on the market, mainly including friction damping structures, elastic damping, oil damping structures, and interference damping mechanisms. The advantages and disadvantages of these damping structures are quite obvious. Friction damping relies on friction, has a simple structure and low cost, but is subject to wear. Elastic damping has a buffering effect, but is prone to elastic fatigue. Oil damping has good shock absorption, but its structure is complex, requires high sealing, and cannot achieve instant stop. Interference damping has a simple structure, but the plastic is prone to aging, and the damping force is not adjustable. These damping structures can meet basic damping needs in various industries, but they cannot withstand external forces. For example, car mounts, laptop opening and closing mechanisms, and desk lamp adjustments all have basic damping forces, but once subjected to external forces, their adjusted angles will inevitably change. If used in windy outdoor locations, on equipment with severe vibrations, or on heavy lighting or instruments, the above damping forces will not be able to withstand them, and their adjustment angles will change or even fail with typhoons or frequent equipment vibrations. Damping structures on the market are all customized for specific products and cannot be used in other products or fields, nor can they be sold as standalone products on the market. Summary of the Invention

[0003] The purpose of this invention is to provide a rotary damping structure with a built-in switch to solve the above problems.

A switch knob is mounted on the end of the switch sleeve away from the switch shaft core. A bolt is provided on the inner side of the switch shaft core. A friction plate is provided between the rotating component and the fixed component of the product. The friction plate is located between the rotating component and the fixed component of the product. The bolt passes through the switch shaft core, the friction plate, and the rotating component of the product and is detachably connected to a nut. A reset component is provided between the switch shaft core and the switch knob.

A regular hexagonal structure is provided on the inner side of the switch shaft. The bolt passes through the central hole and one end of the bolt is embedded in the regular hexagonal structure.

[0007] Preferably, the selective synchronous rotation structure includes a gear coincidence limiting groove and a gear separation limiting groove formed on the inner side of the switch housing. The axial depth of the gear coincidence limiting groove is greater than the axial depth of the gear separation limiting groove. A limiting boss is fixedly connected to the outer side of the switch bushing. The limiting boss is selectively movable within the gear coincidence limiting groove and the gear separation limiting groove.

[0008] Preferably, a limiting rib is fixedly connected to one end of the switch knob near the switch sleeve, a limiting groove is formed on the outer side wall of the switch sleeve, the limiting rib is inserted into the limiting groove, and a baffle is fixedly connected to the center of one end of the switch knob near the switch sleeve, the baffle is inserted into the switch sleeve.

[0009] Preferably, the switch knob has several nut holes, and the switch bushing has several fixing nut holes. The switch knob is fixedly connected to the switch bushing via connecting bolts, the nut holes, and the fixing nut holes.

The friction between the rotating and fixed components provides damping and buffering. A bolt and nut lock the switch shaft onto the rotating component. The thickness of the friction plate is set slightly larger than the gap between the rotating and fixed components, ensuring that the friction plate is always under preload. The bolt and nut can be used to adjust the damping force. The switch knob can rotate the switch sleeve. A selective rotation limiting structure between the switch sleeve and the switch shaft allows the switch shaft to rotate synchronously or be locked relative to the switch sleeve. The selective synchronous rotation structure between the switch bushing and the switch housing is used to drive the connection and disengagement between the switch bushing and the switch shaft, thereby realizing synchronous or asynchronous rotation of the switch housing and the switch shaft. Since the switch shaft is mounted on the rotating component and the switch housing is mounted on the fixed component, when the switch shaft and the switch bushing can rotate relative to each other, the friction force of the friction plate is used to achieve damping. The reset component is used to provide axial reset force for the switch bushing. When the switch shaft and the switch bushing are connected together, the rotating component and the fixed component can be locked, which can effectively prevent the fixed angle from becoming unstable due to vibration or other reasons.

Detailed Implementation

[0018] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0019] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0020] Reference Figures 1 to 11 As shown, this embodiment provides a rotary damping structure with a built-in switch, including a switch shaft core 4, which is mounted on the rotating part of the product. A switch sleeve 3 is rotatably provided on the outside of the switch shaft core 4, and the switch sleeve 3 can move axially along the switch shaft core 4. A selective rotation limiting structure is provided between the switch shaft core 4 and the switch sleeve 3. A switch housing 2 is rotatably connected to the outside of the switch sleeve 3. A selective synchronous rotation structure is provided between the switch sleeve 3 and the switch housing 2. The switch housing 2 is mounted on the fixed part of the product. The selective rotation limiting structure and the selective synchronous rotation structure are configured such that the switch housing 2 and the switch shaft core 4 can rotate relative to each other or not rotate relative to each other. A switch knob 1 is installed at the end of the switch sleeve 3 away from the switch shaft core 4. A bolt 7 is provided on the inside of the switch shaft core 4. A friction plate 5 is provided between the rotating part and the fixed part of the product. The friction plate 5 is located between the rotating part and the fixed part of the product. The bolt 7 passes through the switch shaft core 4, the friction plate 5, and the rotating part of the product and is detachably connected to a nut 9. A reset component is provided between the switch shaft core 4 and the switch knob 1.

[0021] This invention installs a friction plate 5 between the rotating and fixed parts of the product. The friction between the rotating and fixed parts of the friction plate 5 provides damping and buffering. The bolt 7 and nut 9 lock the switch shaft 4 onto the rotating part. The thickness of the friction plate 5 is set slightly larger than the gap between the rotating and fixed parts, ensuring that the friction plate 5 is always in a pre-compressed state. The damping force can be adjusted using the bolt 7 and nut 9. The switch knob 1 can drive the switch sleeve 3 to rotate. The selective rotation limiting structure between the switch sleeve 3 and the switch shaft 4 allows the switch shaft 4 to rotate synchronously or be locked relative to the switch sleeve 3. The selective synchronous rotation structure between the switch bushing 3 and the switch housing 2 is used to drive the connection and disengagement between the switch bushing 3 and the switch shaft 4, thereby realizing the synchronous or asynchronous rotation of the switch housing 2 and the switch shaft 4. Since the switch shaft 4 is mounted on the rotating component and the switch housing 2 is mounted on the fixed component, when the switch shaft 4 and the switch bushing 3 can rotate relative to each other, the friction force of the friction plate 5 is used to achieve damping. The reset component is used to provide axial reset force for the switch bushing 3. When the switch shaft 4 and the switch bushing 3 are connected together, the rotating component and the fixed component can be locked, which can effectively prevent the fixed angle from becoming unstable due to vibration or other reasons.

[0022] Further optimization of the scheme: the selective rotation limiting structure includes a gear 4-2 fixedly connected to the outside of the switch shaft core 4. The gear 4-2 is located at one end near the switch shaft sleeve 3. An internal gear ring 3-5 is fixedly connected to the inside of the switch shaft sleeve 3. The gear 4-2 is movably disposed inside the internal gear ring 3-5. The internal gear ring 3-5 is located at one end near the switch shaft core 4. A second limiting platform 4-4 is fixedly connected to the end face of the gear 4-2. A first limiting platform 3-4 is provided on the end face of the internal gear ring 3-5. The first limiting platform 3-4 and the second limiting platform 4-4 cooperate to limit the axial displacement distance of the switch shaft sleeve 3. A limiting platform 4-6 is provided on the switch shaft core 4. The limiting platform 4-6 is movably disposed inside the internal gear ring 3-5. The thickness of the limiting platform 4-6 is not less than the thickness of the internal gear ring 3-5.

[0023] Gear 4-2 can be selectively inserted into the internal gear ring 3-5. When gear 4-2 is inserted into the internal gear ring 3-5 inside the switch sleeve 3, gear 4-2 meshes with the internal gear ring 3-5. The switch shaft core 4 rotates simultaneously, driving the switch sleeve 3 to rotate synchronously, achieving a rigid connection. The switch sleeve 3 and the switch knob 1 are fixedly connected. Simultaneously, due to the selective synchronous rotation structure, the switch sleeve 3 and the switch housing 2 rotate synchronously, ensuring that the switch housing 2 cannot rotate relative to the switch shaft core 4, achieving a fixed state. The axial pressing action of the switch knob 1 can drive the switch sleeve 3 to overcome the spring force of the reset component and move slightly axially. Rotating the switch knob 1 further facilitates this process. At this time, the selective synchronous rotation structure... Under the action of the mechanism, the switch bushing 3 and the switch housing 2 rotate synchronously, the gear 4-2 and the internal gear ring 3-5 disengage from each other, the internal gear ring 3-5 can rotate relative to the switch shaft core 4, and further, the switch housing 2 can also rotate relative to the switch shaft core 4. At this time, the damping torque generated by the friction plate 5 is used to achieve adjustment. The first limiting platform 3-4 and the second limiting platform 4-4 are to prevent the switch shaft core 4 from coming out of the switch bushing 3. The end of the limiting platform 4-6 abuts against the through hole of the fixed component, which can limit the displacement of the switch shaft core 4 in the axial direction. That is, as the pressure of the friction plate 5 increases, the gear 4-2 on the switch shaft core 4 and the internal gear ring 3-5 will not be unable to disengage, thus preventing failure.

[0024] The design is further optimized by fixing several cylindrical bosses 4-1 at the end of the switch shaft core 4 away from the switch shaft sleeve 3. The cylindrical bosses 4-1 are embedded in the rotating parts of the product. A central hole 4-2 is opened in the center of the switch shaft core 4. A regular hexagonal structure 4-5 is provided on the inner side of the switch shaft core 4. The bolt 7 is set through the central hole 4-2, and one end of the bolt 7 is embedded in the regular hexagonal structure 4-5.

[0025] The hexagonal structure 4-5 prevents the bolt 7 from rotating relative to the switch shaft 4, facilitating the adjustment of the locking force of the nut 9 and thus the adjustment of the resistance.

[0026] Further optimization of the scheme: the selective synchronous rotation structure includes a gear coincidence limiting groove 2-4 and a gear separation limiting groove 2-5 opened on the inner side of the switch housing 2. The axial depth of the gear coincidence limiting groove 2-4 is greater than the axial depth of the gear separation limiting groove 2-5. A limiting boss 3-2 is fixedly connected to the outer side of the switch bushing 3. The limiting boss 3-2 is selectively movable in the gear coincidence limiting groove 2-4 and the gear separation limiting groove 2-5.

[0027] The gear coincidence limiting groove 2-4 and the gear separation limiting groove 2-5 are designed to ensure that the switch housing 2 and the switch bushing 3 rotate synchronously. When the limiting boss 3-2 is located in the gear coincidence limiting groove 2-4, the gear 4-2 meshes with the internal gear ring 3-5. When the limiting boss 3-2 is located in the gear separation limiting groove 2-5, the gear 4-2 disengages from the internal gear ring 3-5, and the switch bushing 3 can rotate independently of the switch shaft core 4. Furthermore, the switch housing 2 can rotate relative to the switch shaft core 4, and the friction of the friction plate 5 provides resistance.

[0028] Further optimization of the scheme: a limiting rib 1-1 is fixedly connected to one end of the switch knob 1 near the switch sleeve 3; a limiting groove 3-1 is opened on the outer side wall of the switch sleeve 3; the limiting rib 1-1 is inserted into the limiting groove 3-1; a retaining wall 1-2 is fixedly connected to the center of one end of the switch knob 1 near the switch sleeve 3; the retaining wall 1-2 is inserted into the switch sleeve 3.

[0029] The setting of the limiting rib 1-1 and the limiting groove 3-1 can ensure the consistency of the switch sleeve 3 and the switch knob 1 in synchronizing during the rotation process, and avoid rotation lag or misalignment caused by assembly gap; the retaining wall 1-2 ensures the precise positioning of the switch knob 1 and the switch sleeve 3 in the axial direction.

[0030] The scheme is further optimized by providing several nut holes 1-3 on the switch knob 1 and several fixing nut holes 3-3 on the switch bushing 3. The switch knob 1 is fixedly connected to the switch bushing 3 by connecting bolts 13, nut holes 1-3 and fixing nut holes 3-3.

[0031] The design is further optimized by providing several nut holes 2-3 on the switch housing 2. The switch housing 2 is fixedly connected to the fixed component of the product by mounting bolts 12 and nut holes 2-3.

[0032] To further optimize the design, a conical spring 8 is provided between the nut 9 and the rotating parts of the product, and a friction plate 6 is provided between the conical spring 8 and the rotating parts of the product.

[0033] Friction plate 26 can be made of metal or engineering plastic and is mainly used to increase the force-bearing area of ​​the conical spring 8. The conical spring 8 is made of high-quality stainless steel and is the core component to ensure the long-term effectiveness of the damping structure. Its small hole diameter is slightly smaller than the diameter of the bolt's external thread. The conical spring is screwed into the external thread of the bolt 7. When it is screwed in and contacts friction plate 26, the screwing stops, and nut 9 is used to screw in and press the large end of the conical spring 8 to deform. The degree of deformation depends on the desired damping force of the product. The size of the damping force needs to be adjusted by the user according to the requirements. After the conical spring 8 is screwed in, it meshes with the external thread of the bolt 7. No matter how harsh the environment is later, the position of the conical spring 8 will not change. Once the surfaces of friction plates 1 and 26 are worn due to frequent rotation, the conical spring 8 will release its elasticity to ensure that the damping does not fail.

[0034] Further optimization of the scheme: the switch housing 2 is provided with switch mark 1 2-1 and switch mark 2-2, and a decorative piece 10 is installed on the side of the switch knob 1 away from the switch housing 2. The decorative piece 10 is provided with a switch indicator arrow 10-1.

[0035] The switch markings 1-2-1, 2-2, and 10-1 work together to indicate whether the damping structure is in the open or closed state.

[0036] The solution is further optimized so that the reset component is a compression spring 11, which is installed between the switch shaft core 4 and the switch knob 1.

[0037] The compression spring 11 is provided to provide a restoring force for the axial movement of the switch sleeve 3.
