[0002] In most common lighting fixtures, the lamp head and the bracket can usually rotate relative to each other to adjust the direction of illumination. However, the rotational friction between the lamp head and the bracket in these fixtures is relatively high, resulting in low smoothness of rotation. Users usually need to apply considerable force to rotate them, causing inconvenience in using the fixtures and failing to adequately meet the need for smooth adjustment of the lighting direction.

[0030] like Figure 1 As shown, this embodiment of the present invention provides a rotating assembly 10, including a first rotating member 11, a second rotating member 12, a rotating shaft 13, and a protrusion 14. The second rotating member 12 has a connecting hole 121. One end of the rotating shaft 13 is connected to the first rotating member 11, and the other end of the rotating shaft 13 passes through the connecting hole 121 and connects to the second rotating member 12, thereby movably connecting the first rotating member 11 and the second rotating member 12. The protrusion 14 is disposed on the first rotating member 11 and / or the second rotating member 12, and the first rotating member 11 and the second rotating member 12 abut against each other through the protrusion 14. Moreover, along the axial direction of the rotating shaft 13, the area of ​​the abutting portion on the protrusion 14 is smaller than the area of ​​the overlapping portion of the first rotating member 11 and the second rotating member 12.

[0031] Specifically, the movable connection between the first rotating member 11 and the second rotating member 12 is a connection method that allows the first rotating member 11 and the second rotating member 12 to rotate relative to each other around the rotating shaft 13. To achieve the movable connection between the first rotating member 11 and the second rotating member 12, the connection between one end of the rotating shaft 13 and the first rotating member 11 can be varied, including a fixed connection, a movable connection, a detachable connection, a non-detachable connection, or the rotating shaft 13 and the first rotating member 11 can be integrally formed. When one end of the rotating shaft 13 is movably connected to the first rotating member 11, the connection between the other end of the rotating shaft 13 and the second rotating member 12 can be either a fixed connection or a movable connection. In other words, the movable connection between the first rotating member 11 and the second rotating member 12 can be achieved simply by making the rotating shaft 13 movably connected to at least one of them, providing a relatively flexible design.

[0032] Optionally, the protrusion 14 can be provided at the end of the first rotating member 11 facing the second rotating member 12, in which case the protrusion 14 abuts against the second rotating member 12. Alternatively, the protrusion 14 can be provided at the end of the second rotating member 12 facing the first rotating member 11, in which case the protrusion 14 abuts against the first rotating member 11. Furthermore, protrusions 14 can be provided on both the first rotating member 11 and the second rotating member 12, in which case the protrusion 14 on the first rotating member 11 abuts against the protrusion 14 on the second rotating member 12. With this arrangement, the first rotating member 11 and the second rotating member 12 abut against each other through the protrusions 14. It is understood that the contour shape of the protrusion 14 can typically be designed so that when the first rotating member 11 and the second rotating member 12 rotate relative to each other, they can maintain stable and uninterrupted contact through the protrusion 14, thereby improving the smoothness of rotation. The optional design schemes for the shape of the protrusion 14 will be described in detail in the following embodiments.

[0033] When the first rotating member 11 and the second rotating member 12 rotate relative to each other, the protrusion 14 and the abutting structure will rub against each other, generating a frictional force that hinders rotation. In order to reduce the frictional force, this embodiment of the invention adopts a method in which the area of ​​the abutting portion on the protrusion 14 is smaller than the area of ​​the overlapping portion of the first rotating member 11 and the second rotating member 12 along the axial direction of the rotating shaft 13. In other words, compared with the absence of the protrusion 14, the protrusion 14 acts as a gap, which also reduces the contact area between the first rotating member 11 and the second rotating member 12, thereby reducing the frictional force and making the rotation between the first rotating member 11 and the second rotating member 12 smoother.

[0034] It should be noted that although in theory it is generally believed that the magnitude of friction is independent of the contact area, in reality, changes in the contact area alter the pressure distribution and the material deformation between the two contacting structures. These changes indirectly lead to changes in the coefficient of friction between the two components, thus altering the magnitude of the actual friction. Therefore, the use of the protrusion 14 in this embodiment of the invention to reduce friction by decreasing the contact area is a practical and feasible solution.

[0035] Alternatively, to further reduce friction, the protrusion 14 can be made of a material with a low coefficient of friction, or the surface of the protrusion 14 can be polished to reduce its surface roughness. Additionally, a lubricant or other medium can be filled between the protrusion 14 and the contacting structure; the specific design can be tailored to actual needs.

[0036] Understandably, as long as the requirement for smooth rotation is met, the friction force of rotation does not need to be set too low, so that the position remains stable after rotation adjustment and is not easily loosened. Of course, if the friction force is too low, the contact pressure of the protrusion 14 can be increased or the smoothness of the protrusion 14 can be reduced to control the friction force within a suitable range. This will ensure smooth adjustment while allowing for immediate stopping after adjustment without any change in position.

[0037] Optionally, the second rotating member 12 can usually be set horizontally, so it usually rotates on a horizontal plane relative to the first rotating member 11. This design makes it less susceptible to the influence of gravity on the position of the first rotating member 11 and the second rotating member 12 after relative rotation. There is no need to overcome the effect of gravity through friction to maintain the stability of the rotation position. Therefore, the requirement for the magnitude of the friction between the first rotating member 11 and the second rotating member 12 is lower, and the friction can be set to be smaller to ensure the smoothness of rotation.

[0038] The rotating assembly 10 provided in this embodiment includes a first rotating member 11, a second rotating member 12, a rotating shaft 13, and a protrusion 14. The two ends of the rotating shaft 13 are respectively connected to the first rotating member 11 and the second rotating member 12, thereby movably connecting the first rotating member 11 and the second rotating member 12 and enabling relative rotation of the first rotating member 11 and the second rotating member 12 around the rotating shaft 13. By setting the protrusion 14 on the first rotating member 11 and / or the second rotating member 12, and ensuring that the area of ​​the portion of the protrusion 14 used for abutment is smaller than the area of ​​the overlapping portion of the first rotating member 11 and the second rotating member 12 along the axial direction of the rotating shaft 13, the first rotating member 11 and the second rotating member 12 are spaced apart by the protrusion 14, reducing the contact area between them and thus reducing friction. Only a small force is needed to make the first rotating member 11 and the second rotating member 12 rotate relative to each other, improving the smoothness of rotation.

[0039] In the application of the rotating assembly 10, the first rotating member 11 and the second rotating member 12 are typically connected to two structures that need to rotate relative to each other, thereby driving the relative rotation of the two structures through the rotating members. Taking the application of the rotating assembly 10 in a lamp as an example, the first rotating member 11 and the second rotating member 12 can be connected to the lamp holder and the lamp head of the lamp respectively, enabling the lamp head to rotate relative to the lamp holder to adjust the lighting direction of the lamp. Of course, it is understandable that the rotating assembly 10 has a wide range of applications and is not limited to lamps.

[0040] In some embodiments, such as Figure 1 As shown, along the axial direction of the rotating shaft 13, the projected shape of the protrusion 14 is an arc or a circle. Optionally, when the projected shape of the protrusion 14 is an arc, multiple protrusions 14 can be provided, and the arc length of each protrusion 14 can be the same or different. Moreover, to ensure the smoothness of rotation, protrusions 14 are usually provided on opposite sides of the rotating shaft 13 perpendicular to the axial direction. For example, Figure 1 The projection shape of the protrusion 14 along the axial direction of the rotating shaft 13 is two semi-circular arcs of equal length. The two semi-circular protrusions 14 are located on opposite sides of the rotating shaft 13 perpendicular to the axial direction. This allows the protrusions 14 to contact and support each other on both sides of the rotating shaft 13, maintaining balance during rotation. Alternatively, only one semi-circular protrusion 14 can be provided, with the central angle of the arc greater than 180°. In this configuration, each protrusion 14 has portions located on opposite sides of the rotating shaft 13, which also effectively ensures smooth rotation.

[0041] It should be noted that when both the first rotating member 11 and the second rotating member 12 are provided with protrusions 14, the center of the protrusion 14 should generally be as close as possible to the axis of the rotating shaft 13. This arrangement can reduce the radial offset of the protrusion 14 during rotation, thereby better maintaining stable contact when the first rotating member 11 and the second rotating member 12 rotate relative to each other. In addition, when the shape of the protrusion is set to be arc-shaped, the arc length of the protrusion 14 should not be too short. It is necessary to ensure that the protrusion 14 on the first rotating member 11 and the protrusion 14 on the second rotating member 12 always maintain contact, avoiding the situation where the protrusions 14 of the two rotating members completely separate at a certain rotation angle.

[0042] With the above embodiment, when the first rotating member 11 and the second rotating member 12 rotate relative to each other, the protrusion 14 can rotate around the rotating shaft 13 at the same time to maintain a stable and uninterrupted contact between the first rotating member 11 and the second rotating member 12. When rotating to any angle within the preset rotation range, the rotation can be kept stable and it is not easy to cause problems such as jamming or misalignment, thus improving the smoothness of rotation.

[0043] In some embodiments, at least the portion of the surface of the protrusion 14 used for abutment is a smooth curved surface. Specifically, a smooth curved surface refers to a surface without sharp edges, allowing for a smooth transition at all points on the surface; for example, a sphere is a type of smooth curved surface. To form a smooth curved surface on the surface of the protrusion 14, a direct molding method or a method such as rounding the edges can be used; there are multiple ways to achieve this.

[0044] The above embodiment uses a smooth curved surface on the part of the protrusion 14 that is used for abutment, which helps to reduce the contact area of ​​the protrusion 14, reduce friction, and avoid collisions and scratches caused by sharp edges, thereby further improving the smoothness and stability of rotation.

[0045] In some embodiments, such as Figure 1 As shown, both the first rotating member 11 and the second rotating member 12 are provided with protrusions 14, which protrude relative to each other and abut against each other. With this arrangement, the first rotating member 11 and the second rotating member 12 do not need to be in direct contact, but are indirectly in contact through the provided protrusions 14. Therefore, the main structure of the first rotating member 11 and the second rotating member 12 will not be worn during rotation, which helps to improve the service life of the first rotating member 11 and the second rotating member 12.

[0046] To address wear on the protrusion 14, it is common practice to mount the protrusion 14 on a separate component, allowing for replacement of that component upon wear. For example, in one embodiment, the first rotating member 11 includes a first body 111 and a first friction member 112, with a rotating shaft 13 connected to the first body 111. The first friction member 112 is connected to the first body 111 and located on the side of the first body 111 facing the second rotating member 12, and has a protrusion 14. To ensure the connection between the rotating shaft 13, the first body 111, and the second rotating member 12 while the first friction member 112 is present, a through hole for the rotating shaft 13 to pass through can be provided in the first friction member 112. Alternatively, the shape of the first friction member 112 can be configured as a non-closed shape, such as a "C" shape, to create an opening for the rotating shaft 13 to pass through.

[0047] In the above scheme, the protrusion 14 is provided on the first friction member 112. The connection between the first friction member 112 and the first body 111 can be a detachable connection method such as a threaded connection, so that the first friction member 112 can be disassembled and replaced without replacing the entire first rotating member 11, which helps to reduce component costs and makes the replacement operation convenient.

[0048] Similarly, as in the above scheme, Figure 1 As shown, in some embodiments, the second rotating member 12 includes a second body 122 and a second friction member 123, with a connecting hole 121 formed on the second body 122. The second friction member 123 is connected to the second body 122 and is located on the side of the second body 122 facing the first body 111. A protrusion 14 is provided on the second friction member 123. It is understood that the second friction member 123 can be designed with reference to the first friction member 112 described above, and will not be elaborated here.

[0049] In the above embodiment, the protrusion 14 is provided on the second friction member 123. The connection between the second friction member 123 and the second body 122 can be a detachable connection method such as a threaded connection, so that the second friction member 123 can be disassembled and replaced without replacing the entire second rotating member 12, which helps to reduce component costs and makes the replacement operation convenient.

[0050] In some embodiments, such as Figure 1 and Figure 2 As shown, the second body 122 has a shielding wall 1221 extending toward the first body 111. The shielding wall 1221 is arranged around the connecting hole 121 and together with the end face of the second body 122 where the connecting hole 121 is opened, it forms a receiving cavity 1222. The first friction member 112 and the second friction member 123 are both located in the receiving cavity 1222.

[0051] Specifically, such as Figure 2As shown, the shielding wall 1221 can typically be integrally formed onto the second body 122, eliminating the need for additional components for assembly. The receiving cavity 1222 formed by the end faces of the shielding wall 1221 and the second body 122 with connecting holes 121 primarily accommodates the first friction element 112 and the second friction element 123. It can also allow the rotating shaft 13 to pass through, connecting the first body 111 and the second body 122 by passing through the connecting holes 121. The height of the shielding wall 1221 only needs to cover the first friction element 112 and the second friction element 123. Therefore, the shielding wall 1221 and the first body 111 can typically be spaced apart to avoid contact friction between the shielding wall 1221 and the first body 111, preventing wear and noise.

[0052] The above embodiment employs a shielding wall 1221 on the second body 122 to form a receiving cavity 1222, and places the first friction member 112 and the second friction member 123 inside the receiving cavity 1222. With this design, the shielding wall 1221 covers the first friction member 112 and the second friction member 123, which can improve the aesthetics of the structure and protect the first friction member 112 and the second friction member 123. This can prevent external debris from entering between the first friction member 112 and the second friction member 123 and interfering with their relative rotation, thus ensuring the reliability of the structure.

[0053] In some embodiments, such as Figure 2 and Figure 3 As shown, the first rotating member 11 further includes a first limiting member 113 disposed on the first body 111, and the second rotating member 12 further includes a second limiting member 124 disposed on the second body 122. The first limiting member 113 and the second limiting member 124 abut against each other to limit the range of relative rotation between the first body 111 and the second body 122.

[0054] Specifically, when the first body 111 and the second body 122 rotate relative to each other, the first limiting member 113 moves relative to the second limiting member 124 until one end of the first limiting member 113 abuts against one end of the second limiting member 124, thus limiting the first extreme position of the relative rotation between the first body 111 and the second body 122. Similarly, when the other end of the first limiting member 113 abuts against the other end of the second limiting member 124, thus limiting the second extreme position of the relative rotation between the first body 111 and the second body 122. In this way, the range of relative rotation between the first body 111 and the second body 122 can be limited between the first extreme position and the second extreme position. According to actual needs, the position and shape of the first limiting member 113 and the second limiting member 124 can be designed to adjust the size of the specific limiting range.

[0055] Optionally, such as Figure 2 and Figure 3 As shown, the first limiting member 113 can be an arc-shaped protrusion surrounding the rotating shaft 13, and the second limiting member 124 can be a stop or baffle at the corresponding position. Alternatively, the first limiting member 113 can be a stop or baffle, and the second limiting member 124 can be an arc-shaped protrusion. The aforementioned arc-shaped protrusion can also be replaced by stops or baffles at both ends of the arc; the design is not unique and can be flexibly designed according to the actual situation.

[0056] The above embodiments, by setting the first limiting member 113 and the second limiting member 124, can reliably limit the range of relative rotation between the first body 111 and the second body 122, prevent excessive rotation between the first body 111 and the second body 122 from causing structural damage, and help maintain the reliability of the structure.

[0057] In some embodiments, such as Figure 1 As shown, the rotating assembly 10 also includes a connector 15, which is disposed at one end of the rotating shaft 13 that passes through the connecting hole 121 and is connected to the second body 122. That is, one end of the rotating shaft 13 that passes through the connecting hole 121 is connected to the second body 122 through the connector 15.

[0058] Optionally, the connector 15 can take the form of a snap-fit, snap ring, threaded fastener, etc., and the design scheme is not unique, as long as it can achieve the connection between the rotating shaft 13 and the second body 122. For example, when the connector 15 is in the form of a snap ring, a corresponding slot can be opened at the end of the rotating shaft 13 that passes through the connecting hole 121. Using snap ring pliers, the snap ring is snapped into the slot. In this way, by making the snap ring abut against the second body 122, the axial movement of the rotating shaft 13 relative to the second body 122 is restricted, thereby achieving the connection between the rotating shaft 13 and the second body 122.

[0059] In one implementation scheme, such as Figure 1 , Figure 4 and Figure 5As shown, the connector 15 includes a connecting nut 151, a spring piece 152, and a washer 153. The end of the rotating shaft 13 passing through the connecting hole 121 is threaded, and the connecting nut 151 is threaded into the thread. The spring piece 152 is sleeved on the end of the rotating shaft 13 passing through the connecting hole 121 and is located between the connecting nut 151 and the second body 122. The washer 153 is sleeved on the end of the rotating shaft 13 passing through the connecting hole 121. The washer 153 can be located at the end of the spring piece 152 opposite to the connecting nut 151, or between the spring piece 152 and the connecting nut 151, or both at the end of the spring piece 152 opposite to the connecting nut 151 and between the spring piece 152 and the connecting nut 151. In other words, the connector 15 can be in the form of a threaded fastener and is connected to the rotating shaft 13 by a threaded engagement. The spring 152 can effectively prevent the threaded connection from loosening, and the gasket 153 can buffer the compressive force, making this connection method more reliable, the connection more stable and less prone to loosening, and the extrusion and wear on the structure less.

[0060] For the washer 153 provided at the end of the spring piece 152 opposite to the connecting nut 151, one end of the washer 153 contacts the spring piece 152, and the other end can contact the second body 122 or the second friction member 123. For example, Figure 4 As shown, when the diameter of the connecting hole 121 on the second body 122 is large, the gasket 153 can pass through the connecting hole 121 and contact the second friction member 123. Conversely, as... Figure 5 As shown, when the diameter of the connecting hole 121 on the second body 122 is small, the gasket 153 does not pass through the connecting hole 121, but contacts the position on the second body 122 where the connecting hole 121 is located. When the gasket 153 is in direct contact with the second body 122, the structural strength of the second body 122 is usually higher than that of the second friction member 123, so the stability of the connection is usually better than when the gasket 153 is in contact with the second friction member 123, and the buffering protection effect on the spring 152 is better.

[0061] In the above scheme, to further improve the reliability of the connection, optionally, such as Figure 4 and Figure 5 As shown, multiple connecting nuts 151 can be provided, and the internal threads of some connecting nuts 151 can be turned in the opposite direction to the internal threads of other connecting nuts 151, so that when different connecting nuts 151 become loose, they rotate in opposite directions and inhibit each other, thereby achieving the effect of preventing loosening.

[0062] Optionally, such as Figure 6As shown, a groove 1511 can also be provided on the connecting nut 151. The tool for installing the connecting nut 151 can be inserted into the groove 1511, which makes it convenient for the operator to use the tool to install the connecting nut 151. The shape of the groove 1511 can be designed according to the tool used. For example, it can be set as a straight line or a cross shape.

[0063] like Figure 7 As shown, this embodiment of the utility model also provides a lamp 100, including a lamp holder 20, a lamp head 30, and the aforementioned rotating assembly 10. A first rotating component 11 is connected to either the lamp holder 20 or the lamp head 30, and a second rotating component 12 is connected to the other of the lamp holder 20 and the lamp head 30. Specifically, when the first rotating component 11 is connected to the lamp holder 20, the second rotating component 12 is connected to the lamp head 30. When the first rotating component 11 is connected to the lamp head 30, the second rotating component 12 is connected to the lamp holder 20. It can be understood that the aforementioned "connection" can be two separate components connected through an assembly operation; alternatively, the two structures can be molded into a single unit.

[0064] The lamp 100 provided in this embodiment of the present invention, by applying the above-mentioned rotating component 10, reduces the contact area between the first rotating component 11 and the second rotating component 12 by the protrusion 14 provided in the rotating component 10, thereby reducing the frictional force of the relative rotation of the first rotating component 11 and the second rotating component 12, thereby improving the smoothness of the rotation of the lamp head 30 relative to the lamp holder 20, and enabling smoother adjustment of the orientation of the lamp head 30, resulting in a better user experience for the lamp 100.

[0065] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
