[0033] As people's living standards improve, they pay more and more attention to a healthy lifestyle and are more actively involved in physical exercise. Outdoor camping can be both relaxing and exercising, so it is loved by many people. In order for camping to proceed smoothly and safely at night, camping lights are essential. Camping lights are a kind of movable lighting tool that can provide lighting in the camp, deter wild animals, indicate the location of the camp, etc. When used in the wild, camping lights can be placed on the ground, hung in the air, held in hand, or even worn on the body. In these various usage scenarios, the angle of the light needs to be set differently.
[0034] Currently, the lamps on the market that can be rotated and adjusted and angled are generally fastened with screws. This method requires operation of the screws, which has a poor feel and is not convenient to use. In addition, the screws are prone to failure after being used for a long time, affecting the hovering effect.
[0035] In the related art, a rotating shaft structure with a damping function is connected to the lamp. Relying on the damping effect, the rotatable lamp body can freely stop at any position and angle. Generally, a damping member is added to the rotating shaft structure to achieve the damping function. However, the existing damping rotation mechanism is usually complex in structure, has many parts, and is cumbersome to assemble.
[0036] The present application embodiment provides a damping rotation mechanism 1, referring to Figure 1 , Figure 2 and Figure 3 The damping rotation mechanism 1 includes: a first rotating member 11, a second rotating member 12, a damping member 13 and a rotating shaft 14. The first rotating member 11 is provided with a hinge hole 111; the damping member 13 is accommodated in the hinge hole 111, and the damping member 13 is axially provided with an axial hole 131; the rotating shaft 14 is connected to the second rotating member 11, the rotating shaft 14 passes through the axial hole 131, the rotating shaft 14 is coaxially arranged with the axial hole 131 and the hinge hole 111, and the rotating shaft 14 and the damping member 13 are interference fit and rotatably connected, so that the first rotating member 11 and the second rotating member 12 are rotatably connected.
[0037] In this way, one of the first rotating member 11 or the second rotating member 12 can be used to fix the position, which can meet the needs of fixing with different objects, and the other of the second rotating member 12 or the first rotating member 11 can be used to be fixedly connected with the product body, so that the product body can adjust the rotation angle and position, which can meet the convenience of using the product body in various environments; the first rotating member 11 is provided with a hinge hole 111, for the damping member 13 and the rotating shaft 14 to pass through and connect with the first rotating member 11; the damping member 13 is accommodated in the hinge hole 111, which is used to fix the damping member 13 and the first rotating member 11 to generate a circumferential force, and the damping member 13 is simple, with only one component, and is easy to assemble; the damping member 13 is provided with an axial hole 131 in the axial direction , the rotating shaft 14 is connected to the second rotating member 12, the rotating shaft 14 passes through the shaft hole 131, the rotating shaft 14 is coaxially arranged with the shaft hole 131 and the hinge hole 111, so that the rotating shaft 14 is connected to the first rotating member 11, the rotating shaft 14 and the damping member 13 are rotatably connected, the rotating shaft 14 drives the second connecting member 12 to rotate, the damping member 13 drives the first rotating member 11 to rotate, so that the first rotating member 11 and the second rotating member 12 are rotatably connected, and the rotating shaft 14 and the damping member 13 are interference fit, so that the rotating shaft 14 and the damping member 13 can generate a damping force, and the rotating shaft 14 is connected to the second rotating member 12, so that the first rotating member 11 and the second rotating member 12 are rotatably connected, so that the first rotating member 11 and the second rotating member 12 can be freely stopped at any position and angle. Therefore, the damping rotation mechanism 1 provided in the embodiment of the present application has a simple structure, few parts, simple assembly, and a wide range of applications.
[0038] It should be noted that, refer to Fig.10 The damping rotation mechanism 1 can be applied to a variety of products, and the products here are not limited, and can be household appliances, electronic products, mechanical products, etc. For example, it can be used for lamps, fans, laptops, and various brackets. Among them, one of the first rotating member 11 or the second rotating member 12 is used for fixing the position, which can meet the fixation with different objects in different scenes. For example, one of the first rotating member 11 or the second rotating member 12 can be placed on the ground, on a desktop, hung on a tree, hung on a tent, or fixed on a wearable device, and the fixation of one of the first rotating member 11 or the second rotating member 12 with different objects can be fixed using a fastener or a connecting structure such as a clamping structure, which is not limited here; in addition, the other of the first rotating member and the second rotating member 12 is used to be fixedly connected to the product body, so that the product body can adjust the rotation angle and position, which can meet the convenience of use of the product body in various environments. For example, the product body can be a lamp. When the lamp needs to be placed on the ground, on a desktop, hung on a tree, hung on a tent, or fixed on a wearable device, different lighting angles are required. The lighting angle of the lamp can be adjusted to meet the use in various environments.
[0039] In addition, the damping member 13 can be fixed in the first rotating member 11, and the fixing method can use fasteners, adhesive connection or pin connection, but this requires the provision of holes or adhesives, which has high processing costs and complicated assembly.
[0040] In some embodiments, reference Figure 3 , Figure 5 and Figure 8 At least one first limiting structure 132 is radially arranged on the outer surface of the damping member 13, and at least one second limiting structure 1111 is arranged at a position corresponding to the first limiting structure 132 in the hinge hole 111. The first limiting structure 132 cooperates with the second limiting structure 1111 to fix the damping member 13 and the first rotating member 11 in position.
[0041] In this way, when the damping member 13 is assembled with the first rotating member 11 , the first limiting structure 132 can be directly matched with the second limiting structure 1111 , so the assembly is simple and convenient, and the damping member 13 is easy to process.
[0042] It should be noted that the first limiting structure 132 and the second limiting structure 1111 are engaged to limit the displacement of the damping member 13 in the circumferential and radial directions, so that the damping member 13 is fixedly limited with the first rotating member 11, and the first rotating member 11 is rotated to drive the damping member 13 to rotate, so that the damping member 13 rotates in the circumferential direction. The rotating shaft 14 is fixedly connected with the second rotating member 12, and the damping member 13 and the rotating shaft 14 are interference fit to generate a damping force, so that the first rotating member 11 and the second rotating member 12 can be rotated to any angle and can be maintained at a desired angle, and the product body connected to the first rotating member 11 and the second rotating member 12 can be suspended at a desired angle.
[0043] In addition, the first limiting structure 132 can be a protrusion or a groove, and the second limiting structure 1111 can also be a groove or a protrusion. The first limiting structure 132 and the second limiting structure 1111 are arranged correspondingly. For example, when the first limiting structure 132 is a protrusion, the second limiting structure 1111 is a groove, and when the first limiting structure 132 is a groove, the second limiting structure 1111 is a protrusion. The protrusion is accommodated in the groove so that the damping member 13 and the first rotating member 11 are fixedly limited.
[0044] In addition, a plurality of first limiting structures 132 may be provided on the outer surface of the damping member 13 along the radial direction, and a plurality of corresponding second limiting structures 1111 may be provided at positions in the hinge hole 111 corresponding to the first limiting structures 132 .
[0045] In some embodiments, reference Figure 3 , Figure 5 and Figure 8The outer surface of the damping member 13 is provided with two symmetrical first limiting structures 132, and two second limiting structures 1111 are provided in the hinge hole 111 at positions corresponding to the first limiting structures 132. In this way, the displacement of the damping member 13 along both sides of the radial direction can be better limited, and the two damping members 13 are easy to process, and the elastic deformation of the damping member 13 will not be affected.
[0046] In addition, the damping force generated by the interference fit between the damping member 13 and the rotating shaft 14 may have a weak supporting capacity when supporting a heavier product, and a larger opposite force needs to be generated between the damping member 13 and the rotating shaft 14 so that the damping member 13 generates a larger friction force with the rotating shaft 14 when moving in the circumferential direction, thereby increasing the damping force between the damping member 13 and the rotating shaft 14.
[0047] In some embodiments, reference Figure 3 , Figure 8 and Fig. 9 The hole wall portion of the shaft hole 131 is radially protruding with at least one abutment portion 1311, which abuts against the outer surface of the rotating shaft 14. During the rotation of the rotating shaft 14 relative to the damping member 13, the damping member 13 and the rotating shaft 14 generate a damping force.
[0048] In this way, during the rotation of the rotating shaft 14 relative to the damping member 13, the abutment portion 1311 abuts against the outer surface of the rotating shaft 14. The abutment portion 1311 is squeezed to cause the damping member 13 to undergo elastic deformation. At the same time, a greater radially opposite force is generated between the damping member 13 and the rotating shaft 14, clamping the rotating shaft 14. The interference fit generates a continuous damping force, which causes the damping member 13 to generate a greater friction force with the rotating shaft 14 when it moves in the circumferential direction, thereby increasing the damping force between the damping member 13 and the rotating shaft 14, so that the damping rotation mechanism 1 can support heavier products for angular suspension and support.
[0049] It should be noted that the abutment portion 1311 can be staggered with the first limiting structure 132, and the abutment portion 1311 is arranged in the middle position inside the shaft hole 131, and the abutment portion 1311 has a certain distance from the edges of the shaft hole 131 along the axial sides; and after the surface of the abutment portion 1311 abuts against the rotating shaft 14, the abutment portion 1311 elastically deforms, and the abutment portion 1311 wraps around the rotating shaft 14, the contact area becomes larger, and a greater damping force is generated.
[0050] A plurality of abutment portions 1311 are radially arranged in the inner radial direction of the shaft hole 131, which can be arranged as needed. The more abutment portions 1311 are arranged, the greater the damping force generated. However, too many abutment portions 1311 will make the processing of the damping member 13 complicated and increase the processing cost, and the damping may be too large, making it difficult to rotate the first rotating member 11.
[0051] In some embodiments, reference Figure 3 , Figure 8and Fig. 9 In a possible implementation provided by the embodiment of the present application, two corresponding abutment portions 1311 are radially arranged in the shaft hole 131 to abut against the outer surface of the rotating shaft 14. In this way, a suitable damping force can be generated, which can enable the damping rotation mechanism 1 to support a heavy product to suspend and support at an angle, and can also make it easier to rotate the first rotating member 11.
[0052] It should be noted that the two abutting portions 1311 and the two first limiting structures 132 can be evenly arranged along the circumferential direction of the damping member 13. For example, referring to Figure 8 The two abutting portions 1311 may be symmetrically arranged on the left and right sides of the shaft hole 131 , and the two first limiting structures 132 may be symmetrically arranged on the upper and lower sides of the outer surface of the damping member 13 .
[0053] In addition, when the abutment portion 1311 abuts against the outer surface of the rotating shaft 14, the abutment portion 1311 is squeezed, which will cause the damping member 13 to generate a radial outward force, and the damping member 13 will produce radial deformation after being squeezed. The damping member 13 is in the hinge hole 111, and the inner surface of the hinge hole 111 will limit the elastic deformation of the outer surface of the damping member 13 corresponding to the abutment portion 1311. The damping member 13 is squeezed, which may cause the damping force of the abutment portion 1311 and the rotating shaft 14 to be too large, making it difficult to rotate the first rotating member 11.
[0054] In some embodiments, reference Figure 3 , Figure 5 and Figure 8 A avoiding groove 1112 is provided at a position corresponding to the abutting portion 1311 and the hole wall of the hinge hole 111, so that when the abutting portion 1311 is squeezed, the damping member 13 can be partially accommodated in the avoiding groove 1112.
[0055] In this way, when the abutment portion 1311 abuts against the outer surface of the rotating shaft 14, when the abutment portion 1311 is squeezed, the outer surface of the damping member 13 corresponding to the abutment portion 1311 has enough radial space to deform, and a suitable damping force can be generated, making it easier to rotate the first rotating member 11.
[0056] It should be noted that the avoidance groove 1112 may be in various shapes. For example, the avoidance groove 1112 may be a rectangular, semicircular, or waist-shaped groove.
[0057] In addition, when there are multiple abutment portions 1311, multiple corresponding avoidance grooves 1112 are required. For example, two corresponding abutment portions 1311 are radially arranged in the shaft hole 131 to abut the outer surface of the rotating shaft 14, and two avoidance grooves 1112 are arranged in the corresponding hinge hole 111 at positions relative to the abutment portions 1311.
[0058] In addition, when the rotating shaft 14 passes through the axial hole 131 of the damping member 13, the abutment portion 1311 will abut against the surface of the rotating shaft 14, and the damping member 13 needs to be deformed to be able to be sleeved with the rotating shaft 14. A large friction force will be generated between the abutment portion 1311 and the surface of the rotating shaft 14, and the rotating shaft 14 and the damping member 13 are relatively difficult to assemble. One end of the rotating shaft 14 needs to pass through the axial hole 131, and the shape of one end of the rotating shaft 14 can be set to make it easier to pass through the axial hole 131.
[0059] In some embodiments, reference Figure 6 , Figure 7 and Fig. 9 The rotating shaft 14 has a first end 141 and a second end 142 located at opposite ends. The first end 141 of the rotating shaft is provided with an avoidance groove 1411 in the radial direction so that when the first end 141 of the rotating shaft 14 passes through the shaft hole 131, the abutment portion 1311 and the first end of the rotating shaft 14 are not squeezed.
[0060] In this way, when the first end portion 141 passes through the shaft hole 131, the abutting portion 1311 is accommodated in the avoidance groove 1411, and the abutting portion 1311 slides more easily along the avoidance groove 1411, making it easier for the first end portion 141 to pass through the shaft hole 131. It should be noted that the position of the avoidance groove 1411 corresponds to the position of the abutting portion 1311. The number of the avoidance grooves 1411 is also the same as the number of the abutting portions 1311. For example, referring to Figure 8 and Fig. 9 , two abutting portions 1311 are symmetrically arranged on the shaft hole 131, and two symmetrical avoidance grooves 1411 are also correspondingly arranged on the first end 141 of the rotating shaft 14. The avoidance grooves 1411 and the abutting portions 1311 are adapted to each other in radial height. The avoidance grooves 1411 can cooperate with the third limiting structure 143 at the first end 141. For example, referring to Fig. 9 The avoidance groove 1411 may be the third limiting structure 143 of the first end portion 141 , and the bottom surface of the avoidance groove 1411 may be connected to the fourth limiting structure 122 profile, so that the rotating shaft 14 and the second rotating member 12 are fixedly connected.
[0061] In addition, refer to Figure 6 , Figure 7 , Figure 8 and Fig. 9When assembling the rotating shaft 14, the first end 141 of the rotating shaft 14 can first pass through the fourth limiting structure 121 on one side of the second rotating member 12, then pass through the connecting hole 121 on one side of the second rotating member 12, and then pass through the shaft hole 131 of the damping member 13. At this time, the abutting portion 1311 in the shaft hole 131 contacts the bottom surface of the avoidance groove 1411 in the avoidance groove 1411, and the abutting portion 1311 slides along the avoidance groove 1411 toward the connecting hole 121 on the other side. Finally, the first end 141 passes through the connecting hole 121 on the other side of the second rotating member 12, and then the third limiting structure 143 on the second end 142 of the rotating shaft 14 is surface-connected with the fourth limiting structure 121 on this side of the second rotating member 12, and the third limiting structure 143 on the first end 141 of the rotating shaft 14 is surface-connected with the fourth limiting structure 122 on the other side of the second rotating member 12.
[0062] In addition, during assembly, when the rotating shaft 14 passes through the axial hole 131, the avoidance groove 1411 and the abutment portion 1311 slide in opposite directions, and the axial edge of the abutment portion 1311 will have a protrusion relative to the inner wall of the axial hole 131, and the edge of the avoidance groove 1411 will have a groove wall. The protrusion and the groove wall will abut against each other to limit the position, which may affect the abutment portion 1311 from passing through the axial hole 131, resulting in difficulty in assembling the abutment portion 1311 and the rotating shaft 14.
[0063] In some embodiments, reference Figure 3 , Figure 8 and Fig. 9 The groove wall of the avoidance groove 1411 arranged along the radial direction of the rotating shaft 14 forms a first guide surface 144, and the side wall of the abutment portion 1311 arranged along the radial direction of the rotating shaft 14 and close to the second end portion 142 of the rotating shaft 14 forms a second guide surface 1312. The first guide surface 144 and the second guide surface 1312 are inclined surfaces parallel to each other, so that when the first end portion 141 of the rotating shaft 14 passes through the shaft hole 131, the first guide surface 144 and the second guide surface 1312 are slidingly matched.
[0064] In this way, the first guide surface 144 and the second guide surface 1312 are in parallel contact and cooperate to slide in opposite directions, so as to guide the rotating shaft 14 to move axially, so that the abutting portion 1311 can be more easily inserted into the shaft hole 131, and the surface of the rotating shaft 14 can be abutted against the abutting portion. The protrusion and the groove wall will not abut against each other, so that the rotating shaft 14 can be more conveniently inserted into the shaft hole 131 and abutted against the abutting portion 1311, which facilitates the assembly of the rotating shaft 14 and the damping member 13.
[0065] It should be noted that a second guide surface 1312 can be provided at at least one connection between the axial side edges of the abutment portion 1311 and the inner surface of the shaft hole 131, so that the rotating shaft 14 can be inserted from either end of the shaft hole 131, and the second guide surface 1312 and the first guide surface 144 will cooperate.
[0066] In addition, the abutment portion 1311 abuts against the rotating shaft 14, which will cause the outer surface of the damping member 13 to deform in shape. However, if the deformed area of the damping member 13 is too large, the elastic deformation of the damping member 13 may be hindered. When the abutment portion 1311 is squeezed, the damping member 13 will undergo circumferential deformation after being squeezed, and a deformation space is required.
[0067] In some embodiments, reference Figure 3 and Figure 8 The damping member 13 is provided with at least one deformation groove 133 along the circumferential direction, and one side edge of the deformation groove 133 along the circumferential direction is adjacent to the abutting portion 1311, so that when the abutting portion 1311 is squeezed, the abutting portion 1311 is deformed toward the deformation groove 133. In this way, the deformation groove 133 along one side edge of the circumferential direction is adjacent to the abutting portion 1311, so that when the abutting portion 1311 is squeezed, the abutting portion 1311 can be deformed toward the deformation groove 133, and the deformation space in the circumferential direction is increased, so that the deformation area of the outer surface of the damping member 13 corresponding to the abutting portion 1311 can be reduced, and the outer surface of the damping member 13 is easier to deform, so that the abutting portion 1311 and the rotating shaft 14 generate appropriate damping force, making it easier to rotate the first rotating member 11.
[0068] It should be noted that the abutting portion 1311 may be provided with a deformation groove 133 on both sides of the circumferential edge, so that the abutting portion 1311 can be deformed toward the deformation grooves 133 on both sides, and there is deformation space when the abutting portion 1311 is squeezed toward the two sides of the circumferential deformation. If there are multiple abutting portions 1311, multiple deformation grooves 133 can be provided accordingly. For example, when n abutting portions 1311 are provided, 2n deformation grooves 133 are provided accordingly. For example, referring to Figure 3 and Figure 8 The damping member 13 is provided with four deformation grooves 133 along the circumferential direction, and the deformation grooves 133 are symmetrically arranged on the damping member 13 .
[0069] It should be noted that the two side edges of the deformation groove 133 along the axis are close to the two side edges of the abutment portion 1311 along the axis, and the two side edges of the deformation groove 133 along the circumferential direction are close to the edges of the first limiting structure 132 and the abutment portion 1311 .
[0070] In addition, the connection between the rotating shaft 14 and the second rotating member 12 can be a fixed connection, for example, a threaded connection can be used, the ends of the rotating shaft 14 have threads, and the inner wall of the connecting hole 121 has corresponding threads, but this method requires tools to assist in tightening the threads during assembly, which is laborious and the thread processing is troublesome, which increases the production cost.
[0071] In some embodiments, reference Figure 6 , Figure 7 and Fig. 9The second rotating member 12 is provided with at least one connecting hole 121, the rotating shaft 14 passes through the connecting hole 121 and is connected to the second rotating member 11, at least one end of the rotating shaft 14 is provided with a third limiting structure 143, the second rotating member 12 is provided with a fourth limiting structure 122, and the third limiting structure 143 is connected with the fourth limiting structure 122 in a profile connection so that the rotating shaft 14 is fixed to the second rotating member 12. In this way, it is easier to assemble the rotating shaft 14 with the second rotating member 12, and the rotating shaft 14 can be fixed to the second rotating member 12 only by profile connection without the assistance of tools, and the processing is relatively simple.
[0072] It should be noted that the second rotating member 12 is provided with two connecting holes 121, and the rotating shaft 14 passes through the two connecting holes 121 and is connected to the second rotating member 12; and the third limiting structure 143 can be a limiting protrusion, and the shape of the radial surface of the limiting protrusion can be various, and there is no limitation here. For example, the limiting protrusion can be a semicircular, square, rectangular, triangular, polygonal or irregular shaped protrusion, and accordingly, the fourth limiting structure 122 is a limiting groove that is adapted to the contour of the third limiting structure 143, and the limiting groove can also be a semicircular, square, rectangular, triangular, polygonal or irregular shaped groove.
[0073] Among them, a third limiting structure 143 can be set at both ends of the rotating shaft 14, and the second rotating member 12 is provided with two corresponding fourth limiting structures 122, and the radial surface shapes of the limiting protrusions of the third limiting structures 143 at both ends of the rotating shaft 14 can be different, and the shapes of the limiting grooves corresponding to the two contours of the corresponding fourth limiting structures on the second rotating member 12 can also be different.
[0074] In addition, the third limiting structure 143 can be integrally formed with the rotating shaft 14 , or can be threadedly connected, clamped, etc. to the rotating shaft 14 .
[0075] In addition, if the third limiting structure 143 is formed integrally with the rotating shaft 14, the third limiting structures 143 at both ends may not exceed the radial edges of the rotating shaft 14, but the rotating shaft 14 may easily loosen and slide out along both sides of the axial direction during rotation. Therefore, the third limiting structure 143 at one end of the rotating shaft 14 may not exceed the radial edges of the rotating shaft 14 along the radial edge, so that the rotating shaft 14 can pass through the shaft hole 131 conveniently. Similarly, the third limiting structure 143 at the other end of the rotating shaft 14 may exceed the radial edges of the rotating shaft 14 along the radial edge. In this way, the rotating shaft 14 will not loosen and slide out along the axial direction during rotation, and the rotating shaft 14 may be limited on one side of the axial direction.
[0076] In addition, when the first rotating member 11 rotates relative to the second rotating member 12, it may rotate to a non-preset position, which may lead to unsafe fixation and placement, and even damage the damping rotation mechanism 1. When the second rotating member 12 is connected to the product body and the first rotating member 11 is parallel to the second rotating member 12, a device may be provided to fix the first rotating member 11 and the second rotating member 12 when the rotating shaft 14 needs to be stable and not rotated.
[0077] In some embodiments, reference Figure 1 , Figure 2 and Figure 3 The damping rotation mechanism 1 also includes a stopper 112, which is arranged on the first rotating member 11 or the second rotating member 12. When the first rotating member 11 rotates to a preset position relative to the second rotating member 12, the stopper 112 contacts both the second rotating member 12 and the first rotating member 11 to prevent the first rotating member 11 and the second rotating member 12 from moving relative to each other, and / or, the damping rotation mechanism 1 also includes a first clamping structure 124, which is arranged on the second rotating member 12, and a second clamping structure 113 corresponding to the position of the first clamping structure 124 is arranged on the first rotating member 11. When the first rotating member 11 and the second rotating member 12 rotate to be parallel to each other, the first clamping structure 124 and the second clamping structure 113 are clamped to clamp and fix the first rotating member 11 and the second rotating member 12.
[0078] In this way, the first rotating member 11 can better support the damping rotating mechanism 1 and the product body, and will not rotate to a non-preset position, causing unsafe fixing and placement, or even damaging the damping rotating mechanism 1. The first clamping structure 124 and the second clamping structure 113 are clamped, so that when the second rotating member 12 is connected to the product body, the first rotating member 11 and the second rotating member 12 are fixed when the product usage scenario requires the first rotating member 11 and the second rotating member 12 to be parallel and the rotating shaft 14 to be stable and not rotated, and the clamping structure is convenient to use.
[0079] It should be noted that the stop member 112 is arranged on the first rotating member 11 and extends radially along the hinge hole 111. The stop member 112 is arranged on the first rotating member 11 at a position close to the second rotating member 12. The first rotating member 11 rotates to a preset position. For example, when the first rotating member 11 rotates to a 90-degree position with the second rotating member 12, the stop member 112 abuts against the second rotating member 12.
[0080] In addition, the damping rotation mechanism can be used in a variety of machinery, electronic products, home appliances and other equipment, and is not limited here.

The damping rotation mechanism 1 is usually simple in structure, with few parts, simple to assemble, and has a wide range of applications. The lamp can be adapted to different usage scenarios.
