Description

Technical Field

[0001] This application relates to the field of damping structure technology, and in particular to a damping structure and support. Background Technology

[0002] Ball joint structures, due to their multi-degree-of-freedom adjustability, are widely used in vehicle mounts, gimbals, and other equipment. In related technologies, ball joint structures maintain posture through preset frictional damping between the ball and socket. This damping force depends on the static damping preset during assembly, making it inconvenient to adjust. In practical applications, the fixed damping force cannot meet diverse needs, making it difficult to adapt to the operational requirements of users with different physical characteristics, and also difficult to cope with the posture stability requirements under different working conditions, resulting in a poor user experience. Utility Model Content

[0003] This application provides a damping structure and support, which can solve the problem of inconvenient adjustment of the damping force of damping structures in related technologies.

[0004] In a first aspect, embodiments of this application provide a damping structure, the damping structure including a rotating member and a damping assembly, the rotating member including a ball head, the damping assembly including a base, an adjusting sleeve and a damping element, the adjusting sleeve being sleeved outside the base, the adjusting sleeve including a first connecting portion for a user to hold and drive the adjusting sleeve to move relative to the base to adjust the damping force; the adjusting sleeve and the base enclose to form a damping cavity for accommodating the damping element, the base also having a damping opening communicating with the damping cavity; wherein, the damping element has a damping groove communicating with the damping opening, a portion of the ball head being disposed in the damping groove and another portion passing through the damping opening.

[0005] Secondly, embodiments of this application provide a bracket, the bracket including the damping structure and the equipment bracket, the equipment bracket being detachably mounted on the adjusting sleeve, and the equipment bracket being used to support external equipment.

[0006] Based on the damping structure and bracket of this application embodiment, the ball head of the rotating component is connected to the base, and the adjusting sleeve is sleeved on the outside of the base. The user can hold and manually operate the first connecting part of the adjusting sleeve to drive the adjusting sleeve to move relative to the base. That is, by adjusting the relative position of the adjusting sleeve and the base, the space of the damping cavity can be squeezed or released. By adjusting the squeezing amount of the damping component, the force of the damping component pressing against the surface of the ball head is changed, thereby adjusting the magnitude of the damping force generated by the rotational movement of the ball head. The user can adjust the damping force of the resistance structure based on their own operational convenience and actual working conditions, improving the adjustment convenience of the damping structure. In addition, in the bracket of this application embodiment, the equipment bracket is detachably installed on the adjusting sleeve.

[0010] To make the objectives, technical solutions, and advantages of 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 not intended to limit the scope of this application.

[0011] In multi-angle adjustable sports equipment such as vehicle mounts, ball joint structures allow for flexible steering to meet diverse usage needs. The damping force of the ball joint structure directly affects the user's handling feel and equipment stability. For example, in complex conditions such as bumpy rides, a larger damping force is required to maintain stability; users with weaker hands or who prefer easier operation require a smaller damping force for adjustment. However, traditional ball joint structures have a fixed damping force, which cannot be flexibly adjusted according to the scenario and user needs, limiting the equipment's adaptability and causing operational difficulties or equipment instability for some users, thus affecting the user experience. Therefore, this application provides a damping structure and a mount.

[0012] Please see Figures 1-3 This application provides a damping structure 1, which includes a rotating member 10 and a damping assembly 20. The rotating member 10 includes a ball head 11, and the damping assembly 20 includes a base 21, an adjusting sleeve 22, and a damping element 23. The adjusting sleeve 22 is sleeved on the outside of the base 21 and includes a first connecting portion 221 for a user to hold and manually drive the adjusting sleeve 22 to move relative to the base 21. The adjusting sleeve 22 and the base 21 enclose a damping cavity for accommodating the damping element 23. The base 21 also has a damping opening 210 communicating with the damping cavity. The damping element 23 has a damping groove 230 communicating with the damping opening 210. A portion of the ball head 11 is disposed in the damping groove 230, and the other portion passes through the damping opening 210.

[0013] Based on the aforementioned damping structure 1, the damping element 23 covers at least a portion of the wall surface of the ball head 11. The base 21 and the adjusting sleeve 22 are configured to have an adjustable relative position. The user adjusts the relative position of the base 21 and the adjusting sleeve 22 through the first connecting part 221, squeezing or releasing the space of the damping cavity, thereby adjusting the amount of squeezing of the damping element 23 by the adjusting sleeve 22 and the base 21. In this way, the damping force acting on the surface of the ball head 11 is adjusted by controlling the covering pressure of the damping element 23 on the ball head 11. The adjusting sleeve 22 is sleeved outside the base 21, making it convenient for the user's hand to hold the first connecting part 221 of the adjusting sleeve 22 to adjust the relative position of the base 21 and the adjusting sleeve 22.

[0014] In practical use, users can flexibly adjust the damping force of the damping structure 1 according to hand strength and operating conditions (such as speed, temperature, vibration frequency, etc.). For example, the damping force can be reduced during normal operation or when hand strength is weak, making the rotation adjustment of the damping structure easier and smoother, reducing the difficulty of operation; the damping force can be increased in complex environments such as bumps and vibrations, making the ball joint connection structure stable, maintaining the stability of the equipment position, and improving the reliability of use.

[0015] Please continue reading. Figures 2-3 The base 21 includes a seat body 211 and a second connecting portion 212, the second connecting portion 212 protruding from the outer periphery of the damping opening 210 on the seat body 211. A first connecting portion 221 is sleeved on the outside of the second connecting portion 212 and connects with it. In the damping structure 1 of this embodiment, the seat body 211 is located outside the first connecting portion 221. Users can control the base 21 and the adjusting sleeve 22 to move away from or closer to each other by holding the seat body 211 and the first connecting portion 221 with both hands, without the need for additional tools. Through this simple operation, users can easily reduce or increase the amount of pressure applied to the damping element 23, achieving flexible adjustment of the damping force and improving the convenience and efficiency of user operation.

[0016] In some embodiments, the base 211 is provided with a damping opening 210, and the adjusting sleeve 22 further includes a support portion 222. The support portion 222 is connected to one end of the second connecting portion 212 away from the base 211, and the support portion 222 is used to support the equipment bracket. Optionally, the first connecting portion 221 is detachably connected to the support portion 222, or the first connecting portion 221 and the support portion 222 are integrally formed to improve the overall structural strength of the adjusting sleeve 22.

[0017] In this embodiment, the base 21 and the adjusting sleeve 22 adopt a partially nested structure. The damping element 23 reaches its maximum compression when the base 21 and adjusting sleeve 22 satisfy the condition that at least one of the second connecting portion 212 abuts against the support portion 222 and the first connecting portion 221 abuts against the seat body 211. Furthermore, in the design and manufacturing process, by controlling the dimensions of the second connecting portion 212 and the first connecting portion 221 along the axial direction X of the damping opening 210, the range of compression of the damping element 23 can be adjusted. Technical personnel can customize a suitable damping force adjustment range according to the usage requirements of different equipment, the operating habits of different users, and different usage scenarios.

[0018] In some embodiments, the adjusting sleeve 22 further includes a plurality of anti-slip protrusions 223, which are spaced apart circumferentially along the damping opening 210, and are all connected to the outer peripheral wall of the first connecting portion 221. The shapes of the anti-slip protrusions 223 include, but are not limited to, raised dots, wavy lines, straight stripes, and diagonal stripes. The plurality of anti-slip protrusions 223 are used to increase friction, facilitating user rotation and adjustment of the adjusting sleeve 22.

[0019] In some embodiments, in the axial direction X of the damping opening 210, the support portion 222 is disposed opposite to the damping opening 210, and the support portion 222 seals the end of the first connecting portion 221 away from the seat body 211 to prevent external dust from entering the mating interface between the damping groove 230 and the ball head 11. In the axial direction X of the damping opening 210, the surface of the damping member 23 contacts the surface of the seat body 211 and the surface of the support portion 222, respectively. Thus, when the base 21 and the adjusting sleeve 22 approach each other in the axial direction X of the damping opening 210, the seat body 211 and the support portion 222 approach synchronously and gradually compress the damping member 23. At the same time, the outer peripheral wall surface of the damping member 23 contacts the inner peripheral wall surface of the second connecting portion 212 to form a circumferential constraint on the damping member 23, suppressing the deformation of the damping member 23 in a direction away from the ball head 11, thereby driving the damping member 23 to further cover and compress the ball head 11, maintaining the performance of the damping member 23 in maintaining a stable shape during long-term use.

[0020] Optionally, the seat 211 and the support 222 are arranged opposite each other in the axial direction X of the damping opening 210. When they approach each other, they uniformly compress the damping member 23, reducing local stress concentration. The damping member 23 deforms radially uniformly, and the wall surface of the part where the ball head 11 mates with the spherical surface of the damping member 23 can be uniformly stressed. Both the seat 211 and the support 222 are flat, and their thickness direction is parallel to the axial direction X of the damping opening 210. Thus, the seat 211 and the support 222 occupy less space in the axial direction X of the damping opening 210, making the structure of the damping assembly 20 more compact.

[0021] The support portion 222 has a first main wall surface and a second main wall surface disposed opposite each other in the axial direction X of the damping opening 210. The first main wall surface facing the damping opening 210 abuts against the damping member 23, and the second main wall surface facing away from the damping opening 210 faces the equipment bracket, which supports external equipment. The damping assembly 20 also includes a connector for connecting to the adjusting sleeve 22, the connector enabling a detachable connection between the adjusting sleeve 22 and the equipment bracket. Figure 2 As shown, the second main wall surface of the support 222 is provided with a mounting cavity, and the connector is provided in the mounting cavity and connected to the support 222. For example, the connector can be configured as a magnetic component, which can be detachably connected to the equipment bracket with magnetic attraction function. The flat support 222 provides a larger mounting position for the connector, so that the contact area between the magnetic component and the equipment bracket is larger.

[0022] In some embodiments, the damping element 23 is an elastic element. For example, the damping element 23 may be made of an elastomeric damping material, such as silicone, silicone rubber, or a rubber-plastic composite material. The damping element 23 is used to define the wall surface of the damping groove 230 as a spherical surface. The spherical surface includes, but is not limited to, a hemisphere, a spherical band, and a partial spherical surface that can achieve a spherical fit. The damping element 23 is used to define the wall surface of the damping groove 230 to be suitable for spherical fit with the ball head 11, so that a stable and smooth rotational connection is formed between the ball head 11 and the damping element 23.

[0023] Furthermore, the base 21 and the adjusting sleeve 22 approach each other along the axial direction X of the damping opening 210 to compress the damping element 23, causing it to deform. The elastic recovery tendency of the damping element 23 ensures that it consistently exerts a certain pressure on the ball head 11, thereby providing a continuous damping force. At least a portion of the damping element 23 abuts against the surface of the ball head 11 along a direction forming an angle with the axial direction of the damping opening 210. This multi-directional abutment increases the contact area and friction between the damping element 23 and the ball head 11, further enhancing the damping effect. When the ball head 11 rotates, the abutment forces in different directions can constrain the ball head 11 from multiple angles, making the rotation of the ball head 11 more stable.

[0024] In some embodiments, the base 21 and the adjusting sleeve 22 are configured to have an adjustable relative position in the axial direction X of the damping opening 210. That is, the size of the damping cavity is adjusted by adjusting the fitting depth of the two in the axial direction X of the damping opening 210, thereby adjusting the amount of compression of the damping member 23. Optionally, the first connecting portion 221 of the adjusting sleeve 22 and the second connecting portion 212 of the base 21 are fitted together in the axial direction X of the damping opening 210, and the two abut against each other in a direction perpendicular to the axial direction X of the damping opening 210. This limits the relative displacement of the base 21 and the adjusting sleeve 22 in the direction of the included angle in the axial direction X of the damping opening 210, so as to suppress the shaking, deflection or disengagement of the adjusting sleeve 22 during use.

[0025] In some embodiments, the second connecting part 212 is threadedly connected to the first connecting part 221. Under the mutual abutment of the adjusting sleeve 22 and the damping member 23, the relative positions of the adjusting sleeve 22 and the base 21 can be flexibly positioned by rotating the second connecting part 212 and the first connecting part 221 relative to each other. For example, the outer wall of the second connecting part 212 is provided with an external thread, and the inner wall of the first connecting part 221 is provided with an internal thread. The external thread of the second connecting part 212 and the internal thread of the first connecting part 221 are matched and tightened. The user can adjust the screw depth of the second connecting part 212 by rotating the adjusting sleeve 22, thereby changing the axial X relative position of the base 21 and the adjusting sleeve 22 in the damping opening 210.

[0026] In other embodiments, the second connecting portion 212 is slidably connected to the first connecting portion 221. Along the axial direction X of the damping opening 210, one of the outer walls of the second connecting portion 212 and the first connecting portion 221 is provided with a groove, and the other is provided with a slider, so as to facilitate sliding adjustment of the relative position of the base 21 and the adjusting sleeve 22. In this case, the damping assembly 20 also includes a positioning assembly, which is connected to the base 21 and the adjusting sleeve 22 respectively. The positioning assembly is used to fix the position of the base 21 and the adjusting sleeve 22 after the second connecting portion 212 and the first connecting portion 221 slide relative to each other to a preset position.

[0027] In some embodiments, the positioning assembly includes a first positioning part and a second positioning part. The first positioning part has a pin hole and is disposed on the second connecting part 212. The second positioning part includes a rotating part and a pin post. The rotating part is rotatably mounted on the first connecting part 221. The pin post is disposed at one end of the rotating part. When it is necessary to allow the second connecting part 212 and the first connecting part 221 to slide relative to each other, the other end of the rotating part is acted upon to move the pin out of the pin hole and release the lock. When it is necessary to lock the relative position of the second connecting part 212 and the first connecting part 221, the rotating part is acted upon to insert the pin into the pin hole and lock the two together. Optionally, there are two sets of positioning assemblies. The two sets of positioning assemblies are arranged axially symmetrically about the axial direction of the damping opening 210 to improve the positioning stability of the second connecting part 212 and the first connecting part 221 when locked. Furthermore, the outer peripheral wall of the first connecting part 221 may be provided with a positioning groove for accommodating the second positioning part. When the pin is removed from the pin hole, the end of the rotating part with the pin is raised relative to the outer peripheral wall of the first connecting part 221. When the pin is inserted into the pin hole, the surface of the rotating part smoothly transitions with the outer peripheral wall of the first connecting part 221, preventing the rotating part from colliding with the external structure and improving the stability of the insertion.

[0028] Please see Figure 2 and Figure 4The rotating component 10 also includes a support rod 12, which is connected to the ball head 11 and is located outside the damping assembly 20. In some embodiments, the ball head 11 may be in the shape of a whole sphere, with a portion of the whole sphere located outside the damping cavity and connected to the support rod 12. The whole sphere shape of the ball head 11 can provide a larger range of rotation, making the angle adjustment of the damping structure 1 more flexible.

[0029] In other embodiments, to reduce the overall size of the damping structure 1, the ball head 11 may be configured as a spherical cap, thereby allowing for a reduction in the size of the damping element 23. See also... Figure 5 The ball head 11 is shaped like a spherical cap and includes a rotational surface and an end face. The rotational surface rotates and engages with the inner wall of the damping groove 230. The end face faces the support portion 222, and the support rod 12 is connected to the portion of the ball head 11 facing away from the end face. The extension direction of the support rod is set at an acute angle to the end face. The rotational surface is the spherical cap surface of the spherical cap, and the end face is the bottom surface of the spherical cap.

[0030] Correspondingly, the dimension of the damping member 23 in the axial direction X of the damping opening 210 can be reduced accordingly. The damping member 23 has a first surface 23A facing the support portion 222. The damping member is provided with a clearance opening 231 communicating with the damping groove 230. The clearance opening 231 extends to the first surface 23A in a direction away from the damping groove 230. The clearance opening 231 provides movement space for the ball head 11, which helps to improve motion interference. By providing the clearance opening 231, the ball head 11 is allowed to rotate in an axial direction X perpendicular to the damping opening 210, reducing the interference between the bottom surface of the ball head and the damping member 23 and the adjusting sleeve 22. When the ball head 11 rotates in the damping groove 230, its end face is arranged parallel to or at an angle to the first surface 23A.

[0031] In the axial direction X of the damping opening 210, the distance from the center of the ball head 11 to the first surface 23A is S, and the radius of the ball head 11 is R. S and R satisfy: S < R, that is, the first surface 23A intersects the entire spherical surface containing the rotational surface of the ball head 11. Compared with setting a fully spherical ball head 11, by setting a spherical notch-shaped ball head 11 and coordinating and controlling the size of the damping element 23, the size of the damping structure 1 can be reduced, which helps to improve the portability of the damping structure 1. It is understood that in the axial direction X of the damping opening 210, the depth of the clearance opening 231 will affect the position where the spherical notch interferes with the support part 222. Therefore, by designing the size of the spherical notch and the size of the clearance opening 231, the technicians can reduce the size of the damping structure 1 while meeting the required angle adjustment range of the product.

[0032] In some embodiments, the diameter of the opening of the damping groove 230 is less than or equal to the diameter of the ball head 11, so that the ball head 11 can be installed in the damping groove 230. The base 21 defines the surface of the damping opening 210 as an arc surface, which is tangential to or in contact with the outer wall surface of the ball head 11, so that the ball head 11 can rotate relative to the damping opening 210, and the rotation of the ball head 11 relative to the damping assembly 20 is smoother. The diameter of the portion of the damping opening 210 away from the damping member 23 is smaller than the diameter of the ball head 11, and the damping opening 210 can limit the ball head 11 in its axial direction to prevent the ball head 11 from coming out of the damping opening 210.

[0033] In some embodiments, the surface of the base 21 defining the damping opening 210 slides against the surface of the ball head 11, reducing the frictional resistance between the ball head 11 and the base 21 and reducing jamming. For example, the surface of the base 21 defining the damping opening 210 is a spherical surface, and this spherical surface mates with the outer spherical surface of the ball head 11.

[0034] Please see Figures 6-7 This application provides a bracket, which includes a damping structure 1 and a device bracket 2. The device bracket 2 is used to support external devices, such as mobile phones, tablets, and other electronic devices. The device bracket 2 is detachably mounted on an adjusting sleeve 22, allowing the user to remove the device bracket 2 as needed to adjust the damping force of the damping component 20. In practical use, the device bracket 2 includes, but is not limited to, desktop wireless charging brackets, magnetic wireless charging brackets, etc. Users can disassemble and replace different types of device brackets 2 as needed, thus broadening the applicable scenarios and external devices.

[0035] In some embodiments, the damping component 20 is magnetically connected to the equipment bracket 2. This magnetic connection ensures stability and minimizes wear on both components, maintaining stability and reliability over long-term use. The equipment bracket 2 includes a support frame 31 and a first mating member 32 connected to the support frame 31. The support frame 31 provides support for external equipment. The damping component 20 also includes a second mating member 24, located on the surface of the adjusting sleeve 22 opposite to the damping opening 210. The first mating member 32 and the second mating member 24 are magnetically engaged, allowing the equipment bracket 2 to be detachably mounted on the adjusting sleeve 22.

[0036] Optionally, one of the first mating component 32 and the second mating component 24 can be a magnetic metal, and the other can be a magnetic element. The magnetic force of the magnetic metal and the magnetic element allows the damping assembly 20 to magnetically engage with the equipment bracket 2. For example, the first mating component 32 can be made of a magnetic metal, such as iron, nickel, or cobalt, while the second mating component 24 can be configured as a magnetic element, such as a magnet. In this way, when the equipment bracket 2 approaches the damping assembly 20, the first mating component 32 and the second mating component 24 will attract together due to the magnetic force, thus achieving a stable connection. Conversely, the second mating component 24 can also be made of a magnetic metal, while the first mating component 32 can be configured as a magnetic element. In this way, when the equipment bracket 2 approaches the damping assembly 20, the first mating component 32 and the second mating component 24 will attract together due to the magnetic force, also achieving a stable connection.

[0037] Optionally, both the first mating component 32 and the second mating component 24 are magnetic elements, and the magnetic force between the two magnetic elements enables the equipment bracket 2 and the damping assembly 20 to be magnetically connected. By rationally designing the position and strength of the first mating component 32 and the second mating component 24, the magnetic force distribution can be balanced, reducing connection instability caused by uneven magnetic force.

[0038] In some embodiments, the device bracket 2 is sleeved on the outside of the damping assembly 20, which helps to enhance the connection stability between the device bracket 2 and the damping structure 1, and the device bracket 2 avoids the surface of the base 21 having the damping opening 210, thus preventing the device bracket 2 from interfering with the movement of the rotating member 10.

[0039] In some embodiments, the bracket further includes a mounting assembly 3 for mounting on an external facility, and the rotating member 10 is movably connected to the mounting assembly 3. The rotating member 10 also includes a support rod 12 and a rotating part 13, with the two ends of the support rod 12 connected to a ball head 11 and the rotating part 13, respectively. The mounting assembly 3 includes a first mounting base 41, and the rotating part 13 is rotatably connected to the first mounting base 41. In actual use, the user can adjust the relative angle of the rotating part 13 with respect to the first mounting base 41, or adjust the relative angle of the ball head 11 with respect to the damping assembly 20, to adjust the position of the bracket.

[0040] Please see Figures 8-9 The mounting assembly 3 also includes a second mounting base 42, a first clamping member 43, and a second clamping member 44. The second mounting base 42 is connected to the first mounting base 41. The first clamping member 43 and the second clamping member 44 are both located at the end of the second mounting base 42 opposite to the first mounting base 41. The first clamping member 43 and the second clamping member 44 are used to clamp onto external facilities. The relative positions of the first clamping member 43 and the second clamping member 44 are adjustable to adjust the clamping space between them.

[0041] Optionally, the first clamping member 43 is fixedly connected to the second mounting base 42, and the second clamping member 44 is configured to be movable relative to the second mounting base 42. For example, the mounting assembly 3 also includes a screw pair 45, which is disposed in the second mounting base 42. The second mounting base 42 has a mounting opening, and one end of the second clamping member 44 passes through the mounting opening and is connected to the screw pair 45. The peripheral wall of the second mounting base 42 is hollowed out so that the user can rotate the screw pair 45. The screw pair 45 can then drive the second clamping member 44 to move relative to the second mounting base 42 and the first clamping member 43. By adjusting the clamping space between the first clamping member 43 and the second clamping member 44, the mounting assembly 3 can be installed on external facilities of different sizes.
