Description

Technical Field

[0001] This application relates to the field of camera technology, and more particularly to a camera. Background Technology

[0002] Traditional security camera flip-folding structures primarily use silicone extrusion friction or plastic friction to achieve hinge damping, a design with significant technical drawbacks. First, silicone materials are prone to aging, and plastic parts are easily worn, causing the hinge torque to gradually decrease over time, severely impacting the long-term user experience. Second, due to differences in material properties and assembly processes, it's difficult to guarantee consistent hinge torque between different devices, and the operational feel of products from the same batch may vary significantly.

[0003] To address the aforementioned issues, existing technologies urgently need improvement. Utility Model Content

[0049] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0050] In existing technologies, the folding structure of security cameras generally uses silicone extrusion or plastic friction to provide rotational damping. These structures rely on the inherent properties of the materials to generate friction, but silicone is prone to aging and plastic to wear, causing the damping torque to decrease over time. In applications requiring frequent angle adjustments, users often encounter uneven rotational resistance and loose brackets after prolonged use, directly affecting the device's positioning accuracy and user experience.

[0051] To address these issues, research focused on eliminating material-dependent damping mechanisms. Analysis of the failure modes of traditional structures revealed that uneven pressure distribution on the friction surface and uncontrollable material deformation were the primary causes of torsional dispersion. Therefore, a design approach was proposed that decouple the damping effect from the connecting structure, employing independent damping components in conjunction with rigid connecting parts. This achieves a quantifiable and adjustable damping effect through mechanical coordination, replacing the traditional friction-based structure.

[0052] To resolve the above issues, please refer to Figures 1 to 14This application provides a camera 100, which includes a bracket 110, a camera assembly 20, and a first pivot assembly 30. The first pivot assembly 30 includes a first connecting part 31, a second connecting part 32, and a first damping member 34. The first damping member 34 is located between the first connecting part 31 and the second connecting part 32. The first connecting part 31 is connected to the camera assembly 20, and the second connecting part 32 is connected to the bracket 110. The first damping member 34 dampens the first connecting part 31 under the action of the second connecting part 32, so as to realize the folding of the bracket 110.

[0053] The first connecting part 31 is a mechanical structure that forms a rigid connection with the camera assembly 20. This design ensures that torque is effectively transmitted to the first damping element 34 during rotation. The second connecting part 32 is a load-bearing structure fixed to the bracket 110. Specifically, it can be a threaded sleeve that is interference-fitted with the bracket 110, and the clamping force on the damping element can be adjusted through the threaded connection. The first damping element 34 is an energy-dissipating element independent of the connecting structure, which generates uniform deformation under pressure to provide stable resistance. The first shaft 33 is a metal rod that supports the rotating parts. Specifically, it can be made of stainless steel and machined into a cylindrical rod, with a threaded section at one end to achieve axial constraint. The threaded connection means that the inner hole of the second connecting part 32 is machined with a thread structure that matches the external thread of the first shaft 33. Specifically, it can be machined using CNC machine tools or other methods to form a precision thread fit.

[0054] Specifically, when an external force is applied to the bracket 110, the second connecting part 32 applies axial pressure to the first damping member 34 through threaded tightening. This axial pressure causes the first damping member 34 to undergo elastic deformation. The first shaft 33, as the core load-bearing structure of the shaft assembly, constrains the first connecting part 31 and the second connecting part 32 onto the same axis through a sleeve connection. The threaded fit between the second connecting part 32 and the shaft allows adjustment of the damping member's compression amount through tightening operations, thereby precisely controlling the shaft torque. During folding, the relative rotation between the second connecting part 32 and the first connecting part 31 forces the first damping member 34 to continuously deform, converting mechanical energy into heat energy. The split structure allows for individual adjustment of the threaded depth of the second connecting part 32, precisely controlling the damping member's compression amount, thereby achieving standardized torque setting and ensuring the consistency of the shaft torque during long-term use of the camera 100. Compared with existing technologies, traditional solutions rely on the coefficient of friction between the silicone and plastic contact surfaces, which is significantly affected by temperature, humidity, and wear. This solution eliminates the uncertainty of material friction through a combination of rigid connections and independent damping components. The deformation of the damping component is linearly related to the axial pressure, and the torque parameter can be repeatedly set via thread adjustment. The interference fit of the connection avoids relative slippage, ensuring that the damping effect occurs only in the preset damping component area.

[0055] Through the above technical solution, this application achieves stable and controllable 100-fold damping of the camera. The independent damping component (first damping component 34) cooperates with the adjustable clamping structure (first connecting part 31 and second connecting part 32) to reduce the standard deviation of the factory torque value. The rigid connection design avoids structural gaps caused by long-term use, and the torque attenuation rate is reduced after multiple folding tests. The threaded engagement between the shaft and the second connecting part 32 replaces the traditional silicone friction method, making torque adjustment more precise and controllable, and unaffected by material aging.

[0056] Please see Figure 12 and Figure 13 In some embodiments of this application, the first damping member 34 includes a first gasket 341 and a second gasket 342. The first gasket 341 is in contact with the first connecting portion 31, and the second gasket 342 is located between the first gasket 341 and the second connecting portion 32 and is in contact with the second connecting portion 32. The first gasket 341 is rigid, and the second gasket 342 is elastic.

[0057] The first gasket 341 refers to the friction interface layer that directly contacts the first connecting part 31. Specifically, it can be made of a smooth metal sheet, a polymer composite material, polyoxymethylene (POM), or PA66 (polyamide 66), etc., distributing rotational friction evenly over a larger contact area through planar contact. The second gasket 342 refers to the intermediate buffer layer disposed between the first gasket 341 and the second connecting part 32. Specifically, it can be made of polyurethane or silicone rubber with elastic recovery properties, absorbing impact loads during rotation through material deformation.

[0058] Specifically, when the first rotating shaft assembly 30 is subjected to external force, a stable sliding friction interface is formed between the first gasket 341 and the first connecting portion 31, and the second gasket 342 undergoes elastic compression under the pressure of the second connecting portion 32. This layered structure decomposes the friction force transmission path into two stages: the first gasket 341 undertakes the main friction energy dissipation function, and the second gasket 342 compensates for the assembly gap and maintains a constant contact pressure through elastic deformation. During long-term use, the rigid material properties of the first gasket 341 can avoid the contact pressure attenuation caused by creep of traditional soft materials, while the elastic properties of the second gasket 342 can continuously compensate for the gap expansion caused by wear.

[0059] Compared to existing technologies, the traditional camera 100's hinge uses a single silicone or plastic gasket structure, which is prone to permanent deformation under continuous pressure, leading to a decrease in contact pressure. This solution, by setting a double-layer heterogeneous gasket structure, retains the high wear resistance of rigid materials while utilizing the self-compensating ability of elastic materials, thus resolving the technical contradiction that a single material cannot simultaneously maintain a stable coefficient of friction and long-term pressure retention.

[0060] Through the above technical solution, this application achieves long-term stability of the damping force of the pivot, avoids the torque attenuation caused by material aging, ensures that the bracket 110 of the camera 100 maintains a consistent damping feel during repeated folding operations, and extends the service life of the pivot assembly.

[0061] Please see Figure 14 In some embodiments of this application, the second gasket 342 includes a first surface 3421 facing the second connecting portion 32 and a second surface 3422 facing the first connecting portion 31. The second surface 3422 is a plane. The distance between the first surface 3421 and the second surface 3422 at the middle position of the second gasket 342 is greater than the distance between the first surface 3421 and the second surface 3422 at the edge position of the second gasket 342.

[0062] The second surface 3422 being planar means that it has a continuous and smooth geometric shape. This can be achieved by using mechanical grinding or other processes to create a flat contact surface. This design ensures that a uniform contact area is formed between the second gasket 342 and the first connecting part 31. The distance between the first surface 3421 and the second surface 3422 at the middle position is greater than the distance at the edge position. This means that the second gasket 342 exhibits a gradually changing thickness distribution in its axial cross-section, being thicker in the middle and thinner at the edges. This can be achieved by using stamping or other processes to form a centrally convex arc-shaped structure on the material of the second gasket 342. This structure allows the second gasket 342 to produce asymmetrical elastic deformation when under pressure.

[0063] Specifically, when the second connecting portion 32 applies axial pressure to the second gasket 342, the greater thickness of the central region causes preferential compressive deformation in this area, forming a stress distribution that decreases from the center to the outer periphery. As the rotation continues, the smaller thickness of the edge region limits local deformation, preventing material fatigue due to excessive compression. The planar second surface 3422 maintains stable contact with the first connecting portion 31, preventing sliding friction during rotation. The thickness difference between the center and the edge creates a gradient damping effect, giving the shaft a higher torque threshold in the initial rotation stage while maintaining linear damping output during continuous rotation.

[0064] Compared to existing technologies, traditional damping shafts using uniformly thick shims cause stress concentration at the edges, leading to localized wear and torque attenuation after long-term use. This solution disperses stress to the central area through a gradually varying thickness design, utilizing the material's elastic deformation recovery characteristics to maintain damping stability. A flat contact surface replaces the traditional corrugated or uneven structure, eliminating torque fluctuations caused by surface irregularities.

[0065] Through the above technical solution, this application achieves a uniform distribution of damping force during shaft rotation, solving the problem of inconsistent torque caused by stress concentration in traditional structures. The gradient thickness design allows the gasket to maintain its elastic recovery ability after long-term pressure, avoiding damping attenuation due to material fatigue. The combination of a planar contact surface and a structure that is thicker in the middle and thinner at the edges ensures linear and controllable torque output during rotation, improving the consistency of the user's operating experience.

[0066] Please refer to it again. Figures 1 to 3 In some embodiments of this application, the first connecting part 31 and the second connecting part 32 are both in the shape of a polyhedron. The first connecting part 31 is connected to the camera assembly 20 by an interference fit, and the second connecting part 32 is connected to the bracket 110 by an interference fit, so as to realize the folding of the bracket 110.

[0067] Among them, the polyhedral connector refers to a connector with a polygonal cross-section, specifically a regular hexagonal or regular octagonal prism structure, which achieves mechanical interlocking through the corner faces. The interference fit connection refers to a connection hole size slightly smaller than the outer diameter of the mating component; specifically, a hydraulic press can be used to press the polyhedral connector into the corresponding mounting hole to form a zero-clearance assembly.

[0068] Specifically, the multi-faceted connector utilizes its angular surfaces to form multiple points of contact with the corresponding mounting holes, effectively improving torsional resistance compared to traditional cylindrical contact surfaces. The interference fit achieves a rigid connection between components through physical pressing, eliminating the risk of loosening inherent in traditional threaded fastening or adhesive bonding processes.

[0069] Compared to existing technologies, traditional shaft assemblies use cylindrical connecting surfaces with threaded fastening, which results in torque attenuation due to clearance. This solution combines multi-faceted contact surfaces with an interference fit to form a clearance-free mechanical interlocking structure, preventing loosening after long-term use. Through this technical solution, this application achieves precise control and long-term stability of the shaft assembly's torque value, ensuring torque consistency across products in mass production. The combination of multi-faceted connecting parts and interference fits simplifies the assembly process, eliminating the time-consuming steps of glue curing or thread tightening. The coaxial structure design of the shaft and connecting parts effectively improves the structural strength of the shaft assembly, preventing component deformation caused by uneven stress.

[0070] Please see Figures 1 to 4 In some embodiments of this application, the camera assembly 20 includes a camera 21 and a horizontal turntable 22. The camera 21 is rotatably connected to the horizontal turntable 22, and the horizontal turntable 22 is interference-fitted with the first connecting part 31.

[0071] The horizontal turntable 22 refers to a support component with a rotating structure. Specifically, it can be made of metal or engineering plastic to form a ring-shaped disc, and its edge is provided with a rotation limit structure to constrain the rotation range of the camera 21. The interference fit connection refers to the mechanical interference formed by the difference in the fit dimensions of the shaft and hole. Specifically, it can be implemented by a polygonal shaft and hole structure, so that the horizontal turntable 22 and the first connecting part 31 generate a preset contact pressure during assembly.

[0072] Specifically, the camera 21 is rotatably connected to the horizontal turntable 22, allowing the camera 21 to be angled on a horizontal plane. The horizontal turntable 22 is fixed to the first connecting part 31 by an interference fit. During assembly, rigid contact is formed through the dimensional interference of the polygonal shaft hole structure, eliminating connection gaps. The constant contact pressure generated by this interference fit replaces the frictional damping of traditional silicone or plastic, allowing the rotating shaft assembly to maintain a preset torque value after multiple rotations. As an intermediate load-bearing component, the horizontal turntable 22 not only transmits the rotational freedom required for the adjustment of the camera 21 but also maintains connection stability through the rigid contact surface.

[0073] Compared to existing technologies, traditional solutions using silicone extrusion or plastic friction for damping suffer from torque decay due to material aging. This solution utilizes an interference fit structure, employing constant pressure generated by mechanical interference to replace the variable coefficient of friction, thus avoiding the impact of material property changes on torque stability. The polygonal shaft-hole structure ensures assembly precision while achieving torque consistency across batches through standardized dimensional control.

[0074] Through the above technical solution, this application solves the problem of torque attenuation caused by material wear at the connection between the camera 21 and the first rotating shaft assembly 30, and eliminates the shaking phenomenon caused by gaps in traditional rotating structures. The rigid interference fit structure between the horizontal turntable 22 and the first connecting part 31 ensures the long-term stability of the rotating shaft torque value and the consistency of batch products while maintaining the adjustment flexibility of the camera 21.

[0075] In some embodiments of this application, the horizontal turntable 22 includes a turntable 221, a first protrusion 222 and a connecting shaft 223. The first protrusion 222 is connected to the turntable 221, and the connecting shaft 223 is rotatably connected to the turntable 221. Under the action of external force, the camera 21 can rotate relative to the connecting shaft 223. The first protrusion 222 is interference-fitted with the first connecting part 31.

[0076] Among them, turntable 221 refers to the ring structure that supports the rotation of camera 21. It can be made of injection-molded engineering plastics, etc., and its outer edge is provided with guide 2211 (which can be a protrusion or a groove) to limit the rotation angle of camera 21.

[0077] The first protrusion 222 refers to a columnar structure that extends vertically from the surface of the turntable. Specifically, it can be integrally formed with the turntable 221 or a separate structure. It has polygonal through holes inside to form an interference fit with the first rotating shaft assembly 30.

[0078] The connecting shaft 223 is a structure that is fixedly connected to the turntable and rotatably connected to the camera 21. Specifically, it can be implemented using a columnar structure made of stainless steel (such as a threaded bolt). The camera 21 is threadedly connected to the connecting shaft 223 through the threaded connector 23, so as to drive the camera 21 to rotate horizontally around its axis.

[0079] Specifically, the turntable 221 forms a rotating pair with the camera 21 via the connecting shaft 223. When an external force is applied to the camera 21, the camera 21 rotates horizontally around the axis of the connecting shaft 223. Guide members 2211 (protrusions or grooves) on the edge of the turntable 221 engage with mating members 211 (grooves or protrusions) on the bottom of the camera 21, limiting the rotation angle of the camera 21 to the range of 0-360 degrees. The first protrusion 222 serves as the connection node between the turntable 221 and the first rotating shaft assembly 30. Its polygonal inner hole forms a surface contact with the polygonal structure on the outer surface of the first rotating shaft assembly 30. During the press-fit process, radial pressure is generated through the elastic deformation of the material, creating a rigid connection between the turntable and the rotating shaft assembly without relative displacement. This interference fit method eliminates the need for bolts or adhesives; assembly is completed simply by pressing the rotating shaft assembly vertically into the inner hole of the first protrusion 222, thus eliminating the risk of loosening due to long-term vibration.

[0080] Compared with existing technologies, traditional solutions use threaded connections or plastic friction to fix the turntable 221 and the first rotating shaft assembly 30, which have problems such as complex assembly processes and easy wear of the connecting surfaces. This solution uses a polygonal interference fit structure, which eliminates relative sliding between the mating surfaces and effectively avoids connection failure caused by material wear.

[0081] Through the above technical solution, this application achieves rapid assembly and stable connection between the turntable 221 and the first rotating shaft assembly 30, eliminating displacement deviation between the turntable 221 and the first rotating shaft assembly 30 during the rotation of the camera 21. The mating structure of the guide member 2211 and the mating member 211 ensures that the camera 21 maintains a controllable motion trajectory during horizontal rotation, preventing cable entanglement due to excessive rotation angle. The interference fit ensures that the turntable 221 and the first rotating shaft assembly 30 maintain a constant connection strength during long-term use, avoiding loosening caused by vibration in traditional threaded connections.

[0082] In some embodiments of this application, the first connecting portion 31 includes a plurality of first connecting surfaces 311; the first protrusion 222 has a first connecting hole 224, the first connecting hole 224 is polygonal and has a plurality of first mating surfaces 2241, the first rotating shaft assembly 30 passes through the first connecting hole 224, and the first mating surfaces 2241 are interference-fitted with the first connecting surfaces 311.

[0083] In some embodiments of this application, the second connecting portion 32 includes a plurality of second connecting surfaces 321; the bracket 110 also includes a second protrusion 11, the second protrusion 11 having a second connecting hole 13, the second connecting hole 13 being polygonal and having a plurality of second mating surfaces 131; the second mating surfaces 131 are interference-fitted with the second connecting surfaces 321.

[0084] In this application, the polygonal first connecting hole 224 and second connecting hole 13 of the first protrusion 222 and the second protrusion 11 respectively mate with the polyhedral structure of the first connecting part 31 and the second connecting part 32 of the first rotating shaft assembly 30. This establishes a fixed connection through geometric constraints, eliminating the risk of loosening that may occur with traditional threaded connections. When the first rotating shaft assembly 30 is inserted into the polygonal connecting holes (first connecting hole 224, second connecting hole 13, and first receiving hole 14) of the horizontal turntable 22, multiple planes of the first connecting part 31 or the second connecting part 32 make surface contact with the corresponding planes of the inner walls of the first connecting hole 224 or the second connecting hole 13. Because the contact pressure generated by the interference fit is evenly distributed on each plane, multi-point rigid constraints are formed, effectively preventing relative rotation of the first connecting part 31 and the second connecting part 32 within the first connecting hole 224 and the second connecting hole 13, respectively. Compared with the prior art, the traditional solution uses a circular hole for friction damping, with a single cylindrical contact surface, which is prone to torque attenuation due to material wear. This solution establishes multi-plane contact through polygonal geometric constraints, resulting in a more uniform distribution of contact pressure. This not only avoids plastic deformation caused by local stress concentration but also solves the stability problem of the connection structure between camera 21 and bracket 110.

[0085] In some embodiments of this application, the turntable 221 has a guide member 2211, and the camera 21 has a mating member 211. The guide member 2211 and the mating member 211 cooperate to limit and guide the camera 21 when it rotates. Existing guide structures often use independent limiting parts. In this solution, the guide member 2211 is integrally formed with the turntable, reducing assembly steps while improving structural strength. Traditional interference fits rely on the friction of a single contact surface. This solution uses multi-plane contact to form geometric interlocking, reducing dependence on the material's coefficient of friction. The structural design of the guide member 2211 and the mating member 211 simplifies the assembly process and enables precise control of the rotation angle. The multi-plane contact interference fit improves the torsional resistance of the connection structure, ensuring the stability of damping characteristics during long-term use.

[0086] In some embodiments of this application, the bracket 110 further includes a third protrusion 12, which is positioned opposite to the second protrusion 11, and a first protrusion 222 is located between the second protrusion 11 and the third protrusion 12; the third protrusion 12 has a first receiving hole 14, and one end of the first shaft 33 away from the second connecting portion 32 is received in the first receiving hole 14 and is rotatable relative to the first receiving hole 14.

[0087] When the first shaft 33 rotates, its threaded end is fixed by the second connecting part 32, and the free end rotates within the first receiving hole 14, forming a rotational structure constrained at both ends. This arrangement prevents axial displacement when the first shaft 33 rotates, ensuring that the first damping element 34 is always under uniform pressure, thereby maintaining the stability of the damping force. The symmetrical design of the third protrusion 12 and the second protrusion 11 also simplifies the assembly process; axial positioning can be completed simply by inserting the first shaft 33 into the first receiving hole 14.

[0088] Compared to existing technologies, traditional shaft assemblies employ only a single-sided support structure, and the lack of constraint on the free end of the shaft can easily lead to rotational misalignment, resulting in uneven stress on the damping components. This solution, however, utilizes symmetrical support formed by protrusions on both sides. The first shaft 33 is constrained at both ends by threaded connections and receiving holes, eliminating the risk of rotational misalignment while preserving rotational freedom through the clearance design of the receiving holes. Furthermore, existing technologies require additional positioning components for shaft assembly, while this solution utilizes the clearance fit between the receiving holes and the first shaft 33 to achieve self-positioning, reducing assembly steps.

[0089] Through the above technical solution, this application solves the problem of rotational offset caused by unilateral support in the shaft assembly, ensuring that the damping component maintains a uniform compression state when the shaft rotates, thereby improving the consistency of damping force. Simultaneously, the symmetrical layout of the third protrusion 12 and the second protrusion 11, combined with the receiving hole structure, eliminates the need for complex alignment operations during shaft assembly; positioning can be completed simply by insertion, significantly reducing assembly complexity.

[0090] In some embodiments of this application, the first shaft 33 is a screw, the first connecting part 31 is a rotating nut, and the second connecting part 32 is a fastening nut.

[0091] Please see Figures 1 to 4In some embodiments of this application, the camera 100 further includes a base 50 and a second pivot assembly 40. The structure of the second pivot assembly 40 is the same as that of the first pivot assembly 30. The second pivot assembly 40 includes a second shaft 41, a third connecting part 42, a fourth connecting part 43, and a second damping member 44. The second damping member 44 is located between the third connecting part 42 and the fourth connecting part 43. The third connecting part 42 is interference-fitted with the bracket 110, and the fourth connecting part 43 is interference-fitted with the base 50. The third connecting part 42 and the fourth connecting part 43 are respectively sleeved on the second shaft 41. Under the action of external force, the third connecting part 42 can rotate around the second shaft 41. The fourth connecting part 43 is threadedly connected to the second shaft 41. The first damping member 34 dampens the first connecting part 31 under the action of the second connecting part 32, so as to realize the folding of the bracket 110.

[0092] The second rotating shaft assembly 40 can be implemented using a combination of shafts, connecting parts, and damping components of the same size, used to achieve the folding function between the bracket 110 and the base 50. The second shaft 41 is a rigid support component that passes through the third connecting part 42 and the fourth connecting part 43, and can be formed from metal or similar materials, used to constrain the rotational trajectory of the connecting parts. The third connecting part 42 is a polyhedral structure fixed to the bracket 110, and can be an interference fit with the bracket 110 using a polygonal metal block, used to transmit rotational resistance. The fourth connecting part 43 is a polyhedral structure fixed to the base 50, and can be an interference fit with the base 50 using a polygonal metal block, and is connected to the second shaft 41 via threads, used to adjust the compression of the second damping component 44. The second damping component 44 is a friction assembly disposed between the third connecting part 42 and the fourth connecting part 43, and can be made of elastic pads or composite layered structures, used to generate stable rotational resistance.

[0093] Specifically, the second pivot assembly 40 replicates the structure of the first pivot assembly 30, ensuring that the rotational damping characteristics between the bracket 110 and the base 50 are consistent with those between the camera assembly 20 and the bracket 110. The interference fit between the third connecting part 42 and the bracket 110 forms a rigid connection, avoiding gaps caused by traditional snap-fit ​​or screw fixings and ensuring the initial positioning accuracy of the pivot assembly. The interference fit between the fourth connecting part 43 and the base 50 further enhances the stability of the overall structure. Simultaneously, its threaded connection design allows for adjustment of the axial position of the second shaft 41 by rotation, thereby changing the compression of the second damping element 44 and precisely controlling the rotational resistance. The second shaft 41, as the core load-bearing component, constrains the relative movement trajectory of the third connecting part 42 and the fourth connecting part 43, ensuring that the rotation process always proceeds along a predetermined axis. The second damping element 44 forms a uniform friction interface between the connecting parts, and, in conjunction with the preload adjustment function of the threaded connection, maintains torsional stability during long-term use.

[0094] Compared to existing technologies, traditional solutions rely on silicone or plastic friction for damping, which is prone to torque attenuation due to material aging. This solution, however, utilizes a second pivot assembly 40 with an interference fit structure to achieve multi-directional folding while ensuring consistent torque across all pivot nodes. Existing technologies using snap-fit ​​or screw-fixed connections are prone to assembly gaps, while this solution eliminates gap errors and improves structural rigidity through a polygonal interference fit. Furthermore, the combination of threaded connections and damping components replaces the traditional non-adjustable friction structure, allowing for precise torque calibration during assembly and long-term maintenance.

[0095] Through the above technical solution, this application solves the problem of insufficient stability of the damping shaft structure between the bracket 110 and the base 50 of the camera 100. It achieves multi-directional folding function through a symmetrical shaft assembly, and at the same time uses interference fit and threaded connection to ensure assembly accuracy and torque adjustability, thereby improving the consistency of shaft torque and extending service life.

[0096] Please see Figures 12 to 13 In some embodiments of this application, the second damping member 44 includes a third washer 441 and a fourth washer 442. The third washer 441 contacts the third connecting portion 42, and the fourth washer 442 is located between the third washer 441 and the fourth connecting portion 43 and contacts the fourth connecting portion 43. The third washer 441 is rigid, and the fourth washer 442 is elastic. The functions of the third washer 441 and the fourth washer 442 are the same as those of the first washer 341 and the second washer 342, respectively, and will not be described in detail here.

[0097] Please see Figure 14 In some embodiments of this application, the fourth gasket 442 includes a third surface 4421 facing the fourth connecting portion 43 and a fourth surface 4422 facing the third connecting portion 42. The fourth surface 4422 is planar. The distance between the third surface 4421 and the fourth surface 4422 at the middle position of the fourth gasket 442 is greater than the distance between the third surface 4421 and the fourth surface 4422 at the edge position of the fourth gasket 442. The structure of the fourth gasket being thicker in the middle and thinner at the edges has the same function as the structure of the fourth gasket 442 being thicker in the middle and thinner at the edges, and will not be described in detail here.

[0098] Please see Figures 8 to 13 In some embodiments of this application, the third connecting portion 42 includes a plurality of third connecting surfaces 421; the bracket 110 also includes a fourth protrusion 15, the fourth protrusion 15 having a third connecting hole 16, the third connecting hole 16 being polygonal and having a plurality of third mating surfaces 161, the second rotating shaft assembly 40 passing through the third connecting hole 16, and the third mating surfaces 161 and the third connecting surfaces 421 being interference-fitted.

[0099] Please see Figures 4 to 6In some embodiments of this application, the base 50 includes a first cover 51, on which a fifth protrusion 52 is provided. The fifth protrusion 52 is located on one side of the fourth protrusion 15. The fifth protrusion 52 has a fourth connecting hole 53. The fourth connecting hole 53 is polygonal and has a plurality of fourth mating surfaces 531. The fourth connecting part 43 includes a plurality of fourth connecting surfaces 431, and the fourth mating surfaces 531 are interference-fitted with the fourth connecting surfaces 431.

[0100] Please see Figures 4 to 6 In some embodiments of this application, a sixth protrusion 54 is provided on the first cover 51, the sixth protrusion 54 is positioned opposite to the fifth protrusion 52, and the fourth protrusion 15 is located between the fifth protrusion 52 and the sixth protrusion 54; the sixth protrusion 54 has a second receiving hole 55, and one end of the second shaft 41 away from the fourth connecting part 43 is received in the second receiving hole 55.

[0101] In some embodiments of this application, the second shaft 41 is a screw, the third connecting part 42 is a rotating nut, and the fourth connecting part 43 is a fastening nut.

[0102] The third connecting hole 16 is polygonal, meaning its inner wall is composed of multiple planes. This can be achieved using a hexagonal or square polyhedral structure, increasing the mating area through planar contact. The interference fit between the third mating surface 161 and the third connecting surface 421 means there is dimensional interference between the inner wall plane of the connecting hole and the outer wall plane of the rotating shaft connection. This can be achieved through injection molding tolerance control, ensuring preload during assembly. The fourth connecting hole 53 is polygonal, meaning the connecting hole in the base 50 uses the same polyhedral structure as the connecting hole in the bracket 110. This can be achieved through mold processing to form a uniform hole shape. The second receiving hole 55 is a circular hole on the protrusion of the base 50, which can be machined using drilling technology. The inner diameter of the hole is slightly larger than the outer diameter of the shaft, allowing the shaft to rotate freely but restricting axial displacement.

[0103] Specifically, the third connecting part 42 and the fourth protrusion 15 of the bracket 110 achieve an interference fit through a polygonal third connecting hole 16. Multiple third mating surfaces 161 contact the third connecting surface 421 to form a uniform preload, preventing torque fluctuations caused by gaps during shaft rotation. The fourth connecting hole 53 of the fifth protrusion 52 of the first cover 51 and the fourth connecting part 43 adopt the same polygonal structure, forming a fixed connection through an interference fit during assembly to prevent loosening after long-term use. The sixth protrusion 54 and the fifth protrusion 52 are arranged opposite each other to form a clamping space, restricting the fourth protrusion 15 between them. The end of the second shaft 41 is inserted into the second receiving hole 55 of the sixth protrusion 54, allowing the shaft to rotate while restricting its axial movement. The standardized machining of the polygonal holes and connecting surfaces ensures that the dimensional tolerances of each connecting surface are consistent, thereby guaranteeing the consistency of shaft torque in mass production.

[0104] Compared to existing technologies, traditional solutions using silicone extrusion or plastic friction for damping suffer from torque attenuation due to material aging. This solution provides damping through an interference fit of a rigid structure, eliminating the impact of material deformation on torque. A polygonal connection structure replaces the traditional circular shaft-hole fit, preventing relative slippage during rotation and ensuring stable torque transmission. A receiving hole at the shaft end replaces the traditional threaded fixing method, simplifying assembly and reducing the precision requirements for component machining.

[0105] Through the above technical solution, this application achieves a rigid connection between the second shaft assembly 40, the bracket 110, and the base 50, ensuring that the shaft torque remains stable during long-term use. The polygonal interference fit structure eliminates the influence of assembly clearance on torque, ensuring a high degree of consistency in torque values ​​for batch products. The mating design of the shaft receiving hole and the clamping protrusion reduces assembly complexity, allowing the shaft to be fixed without the need for additional fasteners.

[0106] Please see Figures 4 to 6 In some embodiments of this application, the base 50 further includes a second cover 56, and the first cover 51 and the second cover 56 are detachably connected; the second cover 56 has a first clearance groove 561.

[0107] Please see Figures 15-16 When the bracket 110 is in the retracted state, it is housed within the first clearance groove 561. (See also...) Figures 1 to 2 When the bracket 110 is in the unfolded state, the end of the bracket 110 connected to the camera assembly 20 is outside the first clearance groove 561.

[0108] In some embodiments of this application, the fifth protrusion 52 and the sixth protrusion 54 extend from the first clearance groove 561.

[0109] In some embodiments of this application, the first cover 51 is provided with at least one third receiving hole 57; the camera 100 also includes a magnetic element 58, which is disposed within the third receiving hole 57, and the first cover 51 is magnetically connected to other external components through the magnetic element 58. The external components may be structures such as walls or baffles that have magnetic structures or are made of metal.

[0110] In some embodiments of this application, a seventh protrusion 59 is provided on the surface of the first cover facing the second cover, and a magnetic element 58 is housed in the seventh protrusion 59; the bracket 110 also includes a bracket body 17, which has a second clearance groove 171. When the bracket 110 is in the storage state, the second clearance groove 171 is used to avoid the seventh protrusion 59.
