[0032] like Figures 1 to 4 As shown, an embodiment of the present invention provides a rotating assembly 1, comprising a first rotating member 11, a second rotating member 12, and a damping member 13. The second rotating member 12 is rotatably connected to the first rotating member 11, so that the first rotating member 11 and the second rotating member 12 can rotate relative to each other. According to different designs, the first rotating member 11 and the second rotating member 12 can form an axis-rotating structure similar to a wheel, or a point-rotating structure similar to a spherical hinge. The damping member 13 is connected to the first rotating member 11 and abuts against the second rotating member 12. The damping member 13 is used to at least squeeze the second rotating member 12 to apply frictional resistance to the second rotating member 12. A friction structure 131 for increasing frictional resistance is provided at least on the side where the damping member 13 abuts against the second rotating member 12. The friction structure 131 has a protrusion 1311 relatively close to the second rotating member 12 and a recessed portion 1312 relatively far away from the second rotating member 12.

[0033] Specifically, the damping member 13 is a component that can apply frictional resistance. The damping member 13 is usually made of a material with a soft texture and a large friction coefficient, such as plastic, rubber, etc. When the damping member 13 is connected to the first rotating member 11 and abuts against the second rotating member 12, it can apply frictional resistance to the second rotating member 12 to hinder the relative rotation between the first rotating member 11 and the second rotating member 12. During use, the user can apply external force to the first rotating member 11 and / or the second rotating member 12 as needed, so that the first rotating member 11 and the second rotating member 12 overcome the frictional resistance of the damping member 13 and rotate relative to each other. When the rotation reaches the specified relative position, the user stops applying force, and the first rotating member 11 and the second rotating member 12 can quickly stop relative rotation and maintain a certain relative position relationship under the friction of the damping member 13, thereby achieving the effect of adjusting and maintaining the relative position.

[0034] Optionally, the damping member 13 is connected to the first rotating member 11 in any manner, and may be abutted, relatively fixed detachable connection, integrally formed, etc. When the damping member 13 abuts the first rotating member 11, the damping member 13 is usually arranged between the first rotating member 11 and the second rotating member 12, so that it squeezes the first rotating member 11 and the second rotating member 12 at the same time, applying frictional resistance to both. When the damping member 13 is relatively fixed to the first rotating member 11, it is only necessary to ensure that the damping member 13 applies frictional resistance to at least the second rotating member 12. The above methods can achieve the effect of the damping member 13 hindering the relative rotation between the first rotating member 11 and the second rotating member 12.

[0035] Specifically, in order to further improve the damping performance of the damping member 13, as shown in FIG. Figure 2 and Figure 4As shown, the damping member 13 is further provided with a friction structure 131 on at least the side contacting the second rotating member 12. The friction structure 131 includes a raised portion 1311 relatively close to the second rotating member 12 and a recessed portion 1312 relatively far from the second rotating member 12. This design allows the friction structure 131 to form an uneven surface on the side contacting the damping member 13 and the second rotating member 12, thereby increasing the roughness of the contact surface and frictional resistance, further improving the damping performance of the damping member 13. This facilitates faster cessation of relative rotation between the first rotating member 11 and the second rotating member 12 when no external force is applied, reduces the influence of inertia, and improves the accuracy of the stopped position. On the other hand, the damping member 13 can abut against the second rotating member through the protrusion 1311 of the friction structure 131 and generate extrusion. During extrusion, the protrusion 1311 will deform inwardly. At this time, the space formed by the recessed portion 1312 can compensate for the deformation of the protrusion 1311, so that most of the deformation generated by the damping member 13 is concentrated on the friction structure 131, reducing the deformation of the main part of the damping member 13, and the overall shape change of the damping member 13 is smaller, which can reduce the fatigue effect of the damping member 13 under long-term and large-scale extrusion deformation, thereby increasing the durability of the damping member 13.

[0036] Optionally, when the damping member 13 is still in contact with the first rotating member 11, a friction structure 131 may be provided on the side of the damping member 13 in contact with the first rotating member 11 to increase the frictional resistance between the damping member 13 and the first rotating member 11. Optionally, the raised portions 1311 and recessed portions 1312 of the friction structure 131 may be arranged at regular intervals or in an irregular arrangement; the raised portions 1311 may be in the form of ridges, bumps, or the like, and the recessed portions 1312 may be in the form of grooves, pits, or the like between adjacent raised portions 1311, as long as the friction structure 131 forms an uneven surface and increases surface roughness. Optionally, to further increase frictional resistance, a similar friction structure may be provided on the second rotating member 12 to further increase the roughness of the contact surface between the damping member 13 and the second rotating member 12.

[0037] The rotating assembly 1 provided in the embodiment of the present invention includes a first rotating member 11, a second rotating member 12, and a damping member 13. The second rotating member 12 is rotatably connected to the first rotating member 11. The damping member 13 is connected to the first rotating member 11 and abuts against the second rotating member 12. The damping member 13 is provided with a friction structure 131 on at least one side abutting against the second rotating member 12. The present invention increases the surface roughness of the damping member 13 by providing the friction structure 131 on the damping member 13, thereby increasing the frictional resistance exerted by the damping member 13, improving the damping performance of the damping member 13, and improving the feel of the rotating assembly 1 during rotation adjustment and the stability of the position after adjustment. At the same time, the recessed portion 1312 of the friction structure 131 compensates for the extrusion deformation of the raised portion 1311, so that most of the extrusion deformation of the damping member 13 is concentrated on the friction structure 131, reducing the amplitude of the overall deformation of the damping member 13, thereby increasing the durability of the damping member 13.

[0038] In some embodiments, such as Figure 2 As shown, the rotating assembly 1 further includes an elastic member 14, which is disposed between the first rotating member 11 and the damping member 13, or may also be disposed between the second rotating member 12 and the damping member 13. The elastic member 14 is used to apply an elastic force to the damping member 13 to increase the rotational friction between the first rotating member 11 and the second rotating member 12.

[0039] Specifically, the elastic member 14 is an elastic member that applies an elastic force to the damping member 13 by generating elastic deformation. Optionally, the elastic member 14 can be a member that can apply an elastic force in a specified direction, such as a spring or an elastic gasket, or a member that can apply an elastic torque, such as a torsion spring. When the elastic member 14 is arranged between the first rotating member 11 and the damping member 13, the elastic force applied by the elastic member 14 can push the damping member 13 to further press against the second rotating member 12, or can twist the damping member 13 to increase its friction torque on the second rotating member 12, thereby increasing the resistance of the damping member 13 to the second rotating member 12. Optionally, when the damping member 13 abuts the first rotating member 11, the elastic member 14 can also be arranged between the second rotating member 12 and the damping member 13, and increase the resistance of the damping member 13 to the first rotating member 11 by applying an elastic force to the first rotating member 11.

[0040] The above embodiment can further increase the rotational friction between the first rotating member 11 and the second rotating member 12 by arranging the elastic member 14 between the first rotating member 11 and the damping member 13, or between the second rotating member 12 and the damping member 13, so that the rotational position adjustment between the first rotating member 11 and the second rotating member 12 is more accurate.

[0041] In some embodiments, such as Figure 2As shown, the elastic member 14 is an elastic gasket having a corrugated structure 141. The corrugated structure 141 defines a space between the corrugated structures for the elastic gasket to elastically deform. Specifically, the corrugated structure 141 is wavy. When the elastic member 14 elastically deforms, the undulating shape of the corrugated structure 141 tends to flatten and has a tendency to recover, thereby generating an elastic force.

[0042] In the above embodiment, the elastic member 14 adopts an elastic gasket with a corrugated structure 141. This design enables the elastic member 14 to have a larger contact surface than the spring, and can more fully contact the damping member 13 and transmit the elastic force. Moreover, compared with an ordinary flat gasket, the gasket with the corrugated structure 141 has more sufficient space when generating elastic deformation, and can better apply elastic force to the damping member 13.

[0043] In some embodiments, such as Figure 1 and Figure 2 As shown, the first rotating member 11 and the second rotating member 12 rotate relative to each other in a first direction. The first rotating member 11 is arranged to penetrate the second rotating member 12 along the first direction, or the second rotating member 12 is arranged to penetrate the first rotating member 11 along the first direction. Two damping members 13 are provided, and the two damping members 13 are respectively arranged on opposite sides of the second rotating member 12 along the first direction, and both of them abut against the second rotating member 12.

[0044] Specifically, the first direction can refer to the dotted line A in the figure, that is, the first rotating member 11 and the second rotating member 12 form a structure that rotates around the dotted line A. At this time, the first rotating member 11 can be arranged along the direction of the dotted line A to pass through the second rotating member 12, or the second rotating member 12 can be arranged along the direction of the dotted line A to pass through the first rotating member 11, so that one of the rotating members is placed between the other rotating member. In this way, when the two rotating members rotate relative to each other, one of the rotating members can have a limiting effect on the other rotating member, which can avoid the problem of the two rotating members moving and misaligning along the axis of rotation, and the rotation is smoother. Furthermore, there are two damping members 13, which are respectively located on the opposite sides of the second rotating member 12 along the dotted line A to simultaneously abut the two side positions of the second rotating member 12. This design makes the friction resistance applied by the damping member 13 to the second rotating member 12 more balanced and uniform, thereby increasing the stability of the relative rotation and adjustment of the relative position of the first rotating member 11 and the second rotating member 12. Further, when there are two damping members 13, such as Figure 2 As shown, elastic members 14 may be further provided between the two damping members 13 and the first rotating member 11 to apply elastic forces to the two damping members 13 , thereby further increasing the rotational friction between the first rotating member 11 and the second rotating member 12 .

[0045] In some embodiments, such as Figure 2 and Figure 4 As shown, the first rotating member 11 is provided with a connecting protrusion 111, and the damping member 13 is provided with a connecting groove 132; and / or, the first rotating member 11 is provided with a connecting groove 132, and the damping member 13 is provided with a connecting protrusion 111. The connecting protrusion 111 is inserted into the connecting groove 132 to connect the first rotating member 11 to the damping member 13.

[0046] Specifically, the connecting protrusions 111 and the connecting grooves 132 generally have matching shapes and corresponding numbers, so that each connecting protrusion 111 can be inserted into the connecting grooves 132 in a one-to-one correspondence, thereby relatively fixing the first rotating member 11 and the damping member 13. Optionally, only the connecting protrusions 111, only the connecting grooves 132, or both the connecting protrusions 111 and the connecting grooves 132 can be provided on the first rotating member 11 or the damping member 13. When both the connecting protrusions 111 and the connecting grooves 132 are provided, the connecting protrusions 111 and the connecting grooves 132 can be arranged at regular intervals or without a specific regularity. It is sufficient to ensure that the connecting structure provided on the first rotating member 11 and the connecting structure provided on the damping member 13 are compatible. Through the above design, the first rotating member 11 and the damping member 13 can be relatively fixedly connected through the cooperation of the connecting protrusions 111 and the connecting grooves 132. The connection is stable and reliable, the transmission effect is good, and the connection structure is simple and easy to manufacture and assemble.

[0047] like Figure 5 As shown, an embodiment of the present invention further provides a lamp, comprising a base 2, a connecting rod 3, a lamp holder 4, and the aforementioned rotating assembly 1. One end of the connecting rod 3 is connected to the base 2, and the other end of the connecting rod 3 is rotatably connected to the lamp holder 4 via the rotating assembly 1, so as to at least adjust the operating angle of the lamp holder 4. A first rotating member 11 is provided at the end of the connecting rod 3 connected to the lamp holder 4, and a second rotating member 12 is provided on the lamp holder 4; alternatively, the first rotating member 11 is provided on the lamp holder 4, and the second rotating member 12 is provided at the end of the connecting rod 3 connected to the lamp holder 4.

[0048] Specifically, the base 2 is used to provide support for the lamp and can be placed on a flat surface such as the ground or a table. The connecting rod 3 is used to connect the lamp head 4 to the base 2. The lamp head 4 is used to provide lighting. The rotating assembly 1 is at least provided between the connecting rod 3 and the lamp head 4, so that the connecting rod 3 and the lamp head 4 are rotatably connected through the rotating assembly 1, so that the lamp can at least adjust the angle of lighting provided by the lamp head 4. Optionally, the rotating assembly 1 can be arranged in such a way that the first rotating member 11 is arranged at the end of the connecting rod 3 connected to the lamp head 4, and the second rotating member 12 is arranged on the lamp head 4. Alternatively, the first rotating member 11 can be arranged on the lamp head 4, and the second rotating member 12 can be arranged at the end of the connecting rod 3 connected to the lamp head 4. Both arrangements can achieve the same effect.

[0049] Optionally, the connection method between the base 2 and the connecting rod 3 is not limited, and can be a fixed connection or a rotating connection, a detachable or non-detachable connection, connected by fasteners such as bolts, or connected to each other by structures such as snaps, etc.

[0050] The lamp provided in an embodiment of the present invention includes the aforementioned rotating assembly 1, a base 2, a connecting rod 3, and a lamp head 4, with the rotating assembly 1 being disposed at least between the connecting rod 3 and the lamp head 4 to enable the lamp to adjust the angle of illumination provided by the lamp head 4. In the lamp provided by the present invention, the rotating assembly 1 has advantages such as good rotational stability, quick and accurate adjustment response, and good durability. Thus, when adjusting the angle of the lamp head 4, the lamp incorporating the rotating assembly 1 has a better operating feel, can accurately adjust to the desired angle and maintain it stably, and provides a good user experience.

[0051] In some embodiments, the end of the connecting rod 3 connected to the base 2 is rotatably connected to the base 2 via a rotating assembly 1, so that at least the connecting rod 3 and the lamp head 4 can be folded or unfolded. Specifically, a first rotating member 11 is disposed at the end of the connecting rod 3 connected to the base 2, and a second rotating member 12 is disposed on the base 2; or the first rotating member 11 is disposed on the base 2, and the second rotating member 12 is disposed at the end of the connecting rod 3 connected to the base 2.

[0052] Specifically, the rotating assembly 1 is not only arranged between the connecting rod 3 and the lamp head 4, but also can be arranged between the connecting rod 3 and the base 2, so that the connecting rod 3 can rotate relative to the base 2, thereby enabling the connecting rod 3 and the lamp head 4 to be folded. Figure 6 As shown, the space occupied by the lamp can be significantly reduced, making it convenient to carry or store. In addition, combined with the advantages of the rotating assembly 1, the angle between the connecting rod 3 and the base 2 can be adjusted. This adjustment process does not require the removal or tightening of any components, making the adjustment operation convenient, giving the lamp more adjustment freedom, more flexible adjustment methods, and a better user experience.

[0053] In some embodiments, such as Figure 5 As shown, the lamp also includes a support leg 5 for providing support. The support leg 5 is connected to the base 2. Specifically, the support leg 5 can be directly connected to the base 2 or rotatably connected to the base 2 via a rotating assembly 1. When the support leg 5 is rotatably connected to the base 2 via the rotating assembly 1, the first rotating member 11 is disposed on the support leg 5 and the second rotating member 12 is disposed on the base 2; alternatively, the first rotating member 11 is disposed on the base 2 and the second rotating member 12 is disposed on the support leg 5.

[0054] Specifically, the support legs 5 are used to provide support for the lamp, usually together with the base 2 to improve the stability of the support. Optionally, according to different designs, two or more support legs 5 can be provided. The support legs 5 can be connected to the base 2 directly to at least provide support, or they can be connected by rotation through the rotating assembly 1. When the support legs 5 are connected to the base 2 by rotation through the rotating assembly 1, the support legs 5 can rotate relative to the base 2 and can adjust the unfolding angle at will. The adjustment is convenient and flexible, can meet the needs of different scenes, and the adjustment operation feels good. At the same time, the support legs 5 can also be folded up, such as Figure 6 As shown, the lamp can be conveniently carried or stored.

[0055] In some embodiments, such as Figure 5 As shown, the base 2 is provided with a connecting rod receiving groove 21, which is used to accommodate at least the connecting rod 3 when the connecting rod 3 and the lamp head 4 are folded; and / or, the base 2 is provided with a supporting foot receiving groove 22, which is used to accommodate the supporting foot 5 when the supporting foot 5 is folded. In the above design, the provision of the connecting rod receiving groove 21 and / or the supporting foot receiving groove 22 on the base 2 can reduce the weight of the base 2 and further save space when the lamp is folded, making the lamp more portable.

[0056] In some embodiments, such as Figure 5 As shown, the interior of the support foot 5 has a cavity, and a reinforcing rib 51 connected to the support foot 5 is provided in the cavity. Specifically, the support foot 5 can be set as a hollow structure, which can reduce the weight of the support foot 5 and make the lamp lighter. At the same time, in order to ensure that the support foot 5 has a stable supporting effect, the reinforcing rib 51 is provided inside the support foot 5. Optionally, the reinforcing rib 51 can be integrally formed with the support foot 5 or fixed by welding, or can be provided in other ways. The reinforcing rib 51 can be provided as follows Figure 5 The mesh structure shown has a better supporting effect. It can also be set in other styles, as long as the supporting effect of the support legs 5 meets the requirements. Through the above design, the support legs 5 can reduce their own weight while ensuring stable support, making the lamp lighter.

[0057] In some embodiments, such as Figure 5As shown, the connecting rod 3 comprises a plurality of coaxial, movably connected connecting sub-rods 31. Each connecting sub-rod 31 is movable along its axis to adjust the length of the connecting rod 3. Specifically, the connecting sub-rods 31 can be telescoped, and the actual usable length of the connecting rod 3 is determined by the length of the extended portion of each connecting sub-rod 31. Locking structures can be provided between the connecting sub-rods 31. When the connecting rod 3 is adjusted to the appropriate length, the connecting sub-rods 31 can be locked to maintain the current length of the connecting rod 3. This design allows for flexible adjustment of the length of the connecting rod 3, thereby making the height of the lamp adjustable and further increasing the freedom and flexibility of lamp adjustment.

[0058] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
