DETAILED DESCRIPTION

[0035] The following will be combined with the accompanying drawings in the embodiments of the present application to clearly describe the technical solutions in the embodiments of the present application. Obviously, the embodiments described are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field are within the scope of protection of this application.

[0036] The terms "first," "second," and the like in the specification and claims of this application are used to distinguish similar objects, and are not used to describe a specific order or precedence. It should be understood that the terms used in this manner are interchangeable where appropriate, so that the embodiments of this application can be implemented in an order other than that illustrated or described herein, and that the objects distinguished by "first," "second," and the like are generally of the same type, and do not limit the number of objects; for example, the first object can be one or more. In addition, the term "and / or" in the specification and claims refers to at least one of the connected objects, and the character " / " generally indicates that the objects connected are in an "or" relationship.

[0037] The rotating device and the lamp provided in the embodiments of the present application are described in detail below through specific embodiments and their application scenarios in conjunction with the accompanying drawings.

[0038] 1 to 24 , an embodiment of the present application provides a rotating device 300 , which may include a rotating arm 320 , a rotating disk 310 , a first rotating shaft mechanism 330 , and a second rotating shaft mechanism 340 .

[0039] The rotating arm 320 can be used to connect to the support 200 of the lamp, and the rotating disk 310 can be used to connect to the lamp base 100 of the lamp. As shown in FIG1 , the first end of the rotating arm 320 is rotatably connected to the rotating disk 310 via a first rotating shaft mechanism 330, and the second end of the rotating arm 320 is rotatably connected to the rotating disk 310 via a second rotating shaft mechanism 340. In this way, the first and second ends of the rotating arm 320 are rotatably connected to the rotating disk 310 via the first rotating shaft mechanism 330 and the second rotating shaft mechanism 340, respectively, so that the force on the rotating arm 320 is balanced during rotation.

[0040] It should be noted that the first end and the second end of the rotating arm 320 may be two ends of the rotating arm 320 located on its own rotation axis, where the rotation axis is the rotation axis of the rotating arm 320 relative to the rotating disk 310.

[0041] Here, the angle of the lamp head 100 can be adjusted by adjusting the relative angle between the rotating disk 310 and the rotating arm 320. As shown in FIG. 4 , the lamp head 100 rotates to a first angle. As shown in FIG. 5 , the lamp head 100 rotates to a second angle.

[0042] In addition, as shown in Figures 12 to 14, the first rotating shaft mechanism 330 and the second rotating shaft mechanism 340 may both include a rotating shaft 332 and a connecting member 333. The rotating shaft 332 may include a connecting portion 3321 and a rotating portion 3322. The rotating portion 3322 is connected to the connecting portion 3321. The connecting portion 3321 can be connected to the rotating arm 320, and the connecting member 333 can be connected to the rotating disk 310. The connecting member 333 is rotatably arranged on the rotating portion 3322. In this way, the rotating connection between the connecting member 333 and the rotating portion 3322 of the rotating shaft 332, and the connection between the connecting portion 3321 of the rotating shaft 332 and the rotating arm 320 can be achieved.

[0043] Furthermore, both the first rotating shaft mechanism 330 and the second rotating shaft mechanism 340 may further include an elastic member 334 and a locking member 335. The elastic member 334 may be sleeved outside the rotating portion 3322, and the connecting member 333 may be clamped between the connecting portion 3321 and the elastic member 334. Alternatively, the elastic member 334 may be located between the connecting portion 3321 and the connecting member 333. The locking member 335 may be connected to the rotating portion 3322 and used to lock the elastic member 334. The elastic member 334 may drive the connecting member 333 to abut against the connecting portion 3321. The locking action of the locking member 335 on the elastic member 334 maintains a certain preload force on the elastic member 334, thereby applying pressure to the connecting member 333, causing the connecting member 333 to abut against the connecting portion 3321 of the rotating shaft 332. In this way, during the rotation of the rotating arm 320 relative to the rotating disk 310, the connecting member 333 can limit the position of the rotating shaft 332, thereby preventing the rotating shaft 332 and the connecting member 333 of the first rotating shaft mechanism 330 and the second rotating shaft mechanism 340 from being offset in position, making it less likely that the rotating arm 320 will be offset in position. Therefore, the rotating arm 320 is not likely to contact and interfere with the rotating disk 310, and the problem of mutual wear between the rotating arm 320 and the rotating disk 310 is less likely to occur.

[0044] Here, due to the elastic effect of the elastic member 334 itself, the elastic member 334 can adjust the rotational torque of the connecting member 333 in real time, thereby controlling the torque of the connecting member 333 and further controlling the torque of the rotating shaft 332.

[0045] In one embodiment, the elastic member 334 may include a plurality of butterfly springs, and the plurality of butterfly springs are sequentially sleeved outside the rotating portion 3322 .

[0046] In addition, the locking member 335 can be connected to the part of the rotating part 3322 away from the connecting part 3321. Specifically, the locking member 335 can be a nut with an external thread provided at a position of the rotating part 3322 away from the connecting part 3321, and the nut is threadedly connected to the rotating part 3322.

[0047] In one embodiment, as shown in Figure 19, the connecting part 3321 may include a first connecting part 3324, which is coaxially connected to the rotating part 3322, and the diameter of the first connecting part 3324 is larger than the diameter of the rotating part 3322. The elastic member 334 can drive the connecting member 333 to abut against the first connecting part 3324.

[0048] In an optional embodiment of the present application, as shown in Figures 8, 10, and 11, a first opening 323 may be provided on the first end of the rotating arm 320, and a second opening 324 may be provided on the second end of the rotating arm 320. The connecting portion 3321 of the first rotating shaft mechanism 330 is at least partially located within the first opening 323, and the connecting portion 3321 of the second rotating shaft mechanism 340 is at least partially located within the second opening 324. In this way, compared to the embodiment described later in which the connecting portions 3321 of the first rotating shaft mechanism 330 and the second rotating shaft mechanism 340 do not extend into the rotating arm 320 but are directly connected to the rotating arm 320, the connection strength and stability of the rotating shaft 332 and the rotating arm 320 are better.

[0049] In other embodiments, the connection portion 3321 of the first rotating shaft mechanism 330 may not extend into the rotating arm 320, and may be directly connected to the first end of the rotating arm 320; the connection portion 3321 of the second rotating shaft mechanism 340 may not extend into the rotating arm 320, and may be directly connected to the second end of the rotating arm 320.

[0050] In one embodiment, the outer circumferential surface of the connecting portion 3321 of the first rotating shaft mechanism 330 can contact the hole wall of the first opening 323, and the two can cooperate at the circumferential upper limit of the connecting portion 3321. In this way, the rotating shaft of the first rotating shaft mechanism 330 and the rotating arm 320 can be relatively fixed in the circumferential direction.

[0051] The outer circumferential surface of the connecting portion 3321 of the second rotating shaft mechanism 340 can contact the hole wall of the second opening 324, and the two can cooperate at the circumferential upper limit of the connecting portion 3321. In this way, the rotating shaft 332 of the second rotating shaft mechanism 340 and the rotating arm 320 can be relatively fixed in the circumferential direction.

[0052] In this way, the rotating shaft 332 of the first rotating shaft mechanism 330 and the rotating arm 320 are relatively fixed in the circumferential direction, and the rotating shaft 332 of the second rotating shaft mechanism 340 and the rotating arm 320 are relatively fixed in the circumferential direction. Compared with the relative rotation of the connecting part 3321 of the first rotating shaft mechanism 330 and the hole wall of the first opening 323, and the relative rotation of the connecting part 3321 of the second rotating shaft mechanism 340 and the hole wall of the second opening 324 described later, it can be ensured that the rotating arm 320 has a certain torque.

[0053] In one embodiment, the connection portion 3321 of the first rotating shaft mechanism 330 may further include a second connection portion 3325. The second connection portion 3325 may be provided with a first flat surface. The walls of the first opening 323 and the second opening 324 may both be provided with a second flat surface, with the first flat surface and the second flat surface being aligned with each other. Here, the second connection portion 3325 of the connection portion 3321 of the first rotating shaft mechanism 330 is located within the first opening 323, and the second connection portion 3325 of the connection portion 3321 of the second rotating shaft mechanism 340 is located and extends into the second opening 324. In this way, the connection portion 3321 of the first rotating shaft mechanism 330 and the wall of the first opening 323 can be positioned in a limited manner along the circumference of the connection portion 3321, and the connection portion 3321 of the second rotating shaft mechanism 340 and the wall of the second opening 324 can be positioned in a limited manner along the circumference of the connection portion 3321.

[0054] Here, the second connection portion 3325 may be connected to the first connection portion 3324 . Specifically, the second connection portion 3325 and the first connection portion 3324 are an integrated structure.

[0055] In addition, the shape of the second connection portion 3325 can be a rectangle, a triangle, an ellipse with a plane, or other shapes with a plane. The first opening 323 and the second opening 324 can both be square holes or openings of other shapes.

[0056] In other embodiments, the connection portion 3321 of the first rotating shaft mechanism 330 extends into the first opening 323 and does not contact the wall of the first opening 323, and the two can rotate relative to each other in the circumferential direction of the connection portion 3321. The connection portion 3321 of the second rotating shaft mechanism 340 extends into the second opening 324 and does not contact the wall of the second opening 324, and the two can rotate relative to each other in the circumferential direction of the connection portion 3321.

[0057] In one embodiment, as shown in FIG6 , the connecting portion 3321 of the first rotating shaft mechanism 330 can be connected to the wall of the first opening 323 via a first fixing member 331, and the connecting portion 3321 of the second rotating shaft mechanism 340 can be connected to the wall of the second opening 324 via a second fixing member 341. Thus, through the fixing action of the first fixing member 331 and the second fixing member 341, the connecting portion 3321 of the first rotating shaft mechanism 330 and the rotating arm 320 are relatively fixed in both the axial direction and the circumferential direction of the rotating shaft 332, and the connecting portion 3321 of the second rotating shaft mechanism 340 and the rotating arm 320 are relatively fixed in both the axial direction and the circumferential direction of the rotating shaft 332. In one embodiment, this can prevent the rotating arm 320 from deviating from the axis of the rotating shaft 332 during rotation.

[0058] In one embodiment, as shown in Figures 8 and 9, a first fixing hole 325 may be provided on the hole wall of the first opening 323, a second fixing hole 326 may be provided on the hole wall of the second opening 324, and a threaded hole 3323 may be provided on the connecting portion 3321. The threaded hole 3323 of the connecting portion 3321 of the first rotating shaft mechanism 330 may be coaxially connected to the first fixing hole 325, and the threaded hole 3323 of the connecting portion 3321 of the second rotating shaft mechanism 340 may be coaxially connected to the second fixing hole 326. The first fixing member 331 may be a first screw, and the second fixing member 341 may be a second screw. The first screw may pass through the first fixing hole 325 and be connected to the threaded hole 3323 of the connecting portion 3321 of the first rotating shaft mechanism 330. The second screw may pass through the second fixing hole 326 and be connected to the threaded hole 3323 of the connecting portion 3321 of the second rotating shaft mechanism 340.

[0059] Here, the diameter of the head of the first screw may be larger than the diameter of the first fixing hole 325 , and the diameter of the head of the second screw may be larger than the diameter of the second fixing hole 326 .

[0060] In other embodiments, the connection portion 3321 of the first rotating shaft mechanism 330 can be only partially inserted into the first opening 323 and circumferentially limited by the hole wall of the first opening 323, and the connection portion 3321 of the second rotating shaft mechanism 340 can be only partially inserted into the second opening 324 and circumferentially limited by the hole wall of the second opening 324. When the cam 320 is in the unlocked position, the cam 320 will be in the unlocked position, and the cam 320 will be in the unlocked position.

[0061] In an optional embodiment of the present application, as shown in Figures 1 and 9, a wire threading hole 327 can be provided on the rotating arm 320. The wire threading hole 327 is used for the wire 400 to pass through and then be electrically connected to the light source in the lamp holder 100. In this way, the wire 400 can be avoided from being exposed, and the aesthetics and safety of the lamp can be improved. In addition, the wire threading hole 327 is located between the first opening 323 and the second opening 324. The rotating disk 310 can be provided with a wire trough 311. The wire trough 311 can be used to accommodate the excess part of the wire 400. In this way, the excess wire 400 can be avoided from being exposed. The groove wall of the wire trough 311 can be provided with an opening 312, and the wire threading hole 327 can be arranged opposite to the opening 312. In this way, it is convenient for the wire 400 to extend into the wire trough 311.

[0062] In other embodiments, the wire hole 327 may not be provided on the rotating arm 320, and the wire 400 may be electrically connected to the light source in the lamp holder 100 outside the rotating device 300. In addition, the rotating disk 310 may not be provided with the wire groove 311.

[0063] In one embodiment, as shown in FIG7 , the rotating disk 310 may be provided with a through hole 313, into which a portion of the rotating arm 320 extends. Furthermore, the rotating disk 310 may be provided with a first mounting slot 314 and a second mounting slot 315. The first mounting slot 314 and the second mounting slot 315 may be located on either side of the through hole 313. Both the first mounting slot 314 and the second mounting slot 315 may be connected to the through hole 313. The first rotating shaft mechanism 330 may be at least partially located within the first mounting slot 314, and the second rotating shaft mechanism 340 may be at least partially located within the second mounting slot 315. In this manner, the space occupied by the rotating device 300 may be reduced.

[0064] In addition, the first mounting groove 314 and the second mounting groove 315 can be set on the end surface where the rotating disk 310 is connected to the lamp holder 100. In this way, the first rotating shaft mechanism 330 and the second rotating shaft mechanism 340 can be avoided from being exposed, which can improve the aesthetics of the lamp.

[0065] In one embodiment, the first opening 323 and the second opening 324 can both be blind holes to prevent the first opening 323 and the second opening 324 from being connected to the wire threading hole 327, so as to prevent the connecting portion 3321 of the rotating shaft 332 from interfering with the wire 400 when connecting the connecting portion 3321 of the rotating shaft and the rotating arm 320.

[0066] In one embodiment, as shown in Figures 15 and 16, the connector 333 may include a connector sleeve 3331 and at least two fixing portions 3332. The connector sleeve 3331 may be sleeved over the rotating portion 3322 and may rotate relative to the rotating portion 3322. The fixing portions 3332 may be distributed along the circumference of the connector sleeve 3331, and each fixing portion 3332 may be connected to the connector sleeve 3331, and each fixing portion 3332 may be connected to the rotating disk 310. In this manner, compared to the method described below of connecting the rotating disk 310 and the connector sleeve 3331 via only one fixing portion 3332, the strength and stability of the connection between the connector 333 and the rotating disk 310 may be effectively improved.

[0067] In one embodiment, the connecting member 333 may include two fixing portions 3332, and the two fixing portions 3332 may be distributed along the circumference of the connecting sleeve 3331. The two fixing portions 3332 may be respectively located on both sides of the connecting sleeve 3331 and are both connected to the outer wall of the connecting sleeve 3331. In this way, during the long-term rotation of the rotating arm 320, the fixing effect of the two fixing portions 3332 can ensure that the force balance of the connecting sleeve 3331 is maintained.

[0068] In one embodiment, the fixing portion 3332 can be an L-shaped structure, the horizontal portion of the fixing portion 3332 of the first rotating shaft mechanism 330 can be connected to the bottom of the first mounting groove 314, and the vertical portion of the fixing portion 3332 of the first rotating shaft mechanism 330 can be connected to one side wall of the through hole 313; the horizontal portion of the fixing portion 3332 of the second rotating shaft mechanism 340 can be connected to the bottom of the second mounting groove 315, and the vertical portion of the fixing portion 3332 of the second rotating shaft mechanism 340 can be connected to the other side wall of the through hole 313.

[0069] In one embodiment, as shown in FIG6 , the fixing portion 3332 can be connected to the rotating disk 310 via a fixing nail 350. Specifically, the fixing portion 3332 can be provided with a mounting hole 3333, and the rotating disk 310 can be provided with a connecting hole. The fixing nail 350 can pass through the mounting hole 3333 and be threadedly connected to the connecting hole. Thus, using the fixing nail 350 to connect the fixing portion 3332 and the rotating disk 310 is structurally simple and can improve the connection strength between the connector 333 and the rotating disk 310.

[0070] In other embodiments, the connecting member 333 may include a connecting sleeve 3331 and a fixing portion 3332. The fixing portion 3332 is located on one side of the connecting sleeve 3331 and connected to the outer wall of the connecting sleeve 3331. The fixing portion 3332 is also connected to the rotating disk 310. In this way, the fixing portion 3332 only connects one side of the connecting sleeve 3331 to the rotating disk 310. During the long-term rotation of the rotating arm 320, the connecting member 333 may be easily deformed or broken due to unbalanced force, thereby causing the connecting member 333 to separate from the rotating disk 310.

[0071] In an optional embodiment of the present application, as shown in FIG18 , both the first rotating shaft mechanism 330 and the second rotating shaft mechanism 340 may include a limiter 336. The limiter 336 may be used to limit the rotation of the connecting member 333 relative to the rotating portion 3322. The limiter 336 may be sleeved outside the rotating portion 3322 and may cooperate with the rotating portion 3322 to limit the circumferential position of the rotating portion 3322. When the connecting member 333 rotates to a desired position relative to the rotating portion 3322, the limiter 336 may prevent the connecting member 333 and the rotating portion 3322 from further rotating relative to each other, thereby maintaining the connecting member 333 at the desired position and fixing the rotating disk 310 at the desired position.

[0072] In one embodiment, the limiting member 336 may be located between the connecting member 333 and the connecting portion 3321 , and the limiting member 336 may be fixedly connected to the connecting portion 3321 .

[0073] Alternatively, the limiting member 336 can be located between the elastic member 334 and the connecting member 333, a limiting plane can be set on the hole wall of the limiting member 336, and an anti-rotation plane can be set on the rotating part 3322, and the limiting plane is in contact with the anti-rotation plane to achieve the limiting cooperation between the limiting member 336 and the rotating part 3322 in the circumferential direction of the rotating part 3322.

[0074] In one embodiment, neither the first rotating shaft mechanism 330 nor the second rotating shaft mechanism 340 includes a limit member 336. When the connecting member 333 rotates to the desired position relative to the rotating portion 3322, the connecting member 333 and the rotating portion 3322 are prevented from continuing to rotate relative to each other by the squeezing effect of the elastic member 334 on the connecting member 333 and the connecting portion 3321 of the rotating shaft 332. However, if the elastic force of the elastic member 334 is small or the gravity of the rotating disk 310 is large, the connecting member 333 cannot be maintained in the desired position, and the rotating disk 310 cannot be fixed in the desired position.

[0075] In one embodiment, as shown in FIG18 , a limiting protrusion 3361 may be provided on the limiting member 336, and a limiting groove 3334 may be provided on the connecting member 333, as shown in FIG16 . The limiting protrusion 3361 may protrude toward the connecting member 333 and be embedded in the limiting groove 3334 to limit the relative rotation between the connecting member 333 and the rotating portion 3322. Thus, the limiting protrusion 3361 and the limiting groove 3334 cooperate to prevent the limiting member 336 and the connecting member 333 from further relative rotation. Furthermore, the limiting protrusion 3361 and the limiting groove 3334 cooperate to prevent the limiting member 336 and the rotating portion 3322 from further relative rotation. Furthermore, the limiting protrusion 3361 and the limiting groove 3334 provide a better degree of positioning than a method in which the contact end surface of the limiting member 336 and the connecting member 333 is provided with a frosted surface, making it less likely that the connecting member 333 will continue to rotate after it has been rotated to the desired position.

[0076] In one embodiment, the limiting protrusion 3361 may protrude toward the connecting member 333 , and the notch of the limiting groove 3334 may be disposed toward the limiting member 336 .

[0077] In other embodiments, the end surface of the limiting member 336 that contacts the connecting member 333 may be a frosted surface.

[0078] In one embodiment, the connecting member 333 may be provided with a plurality of limiting grooves 3334, which may be distributed along the circumference of the connecting sleeve 3331. The limiting protrusion 3361 may be inserted into any of the limiting grooves 3334. In this way, the limiting protrusion 3361 may be inserted into a specific limiting groove 3334 according to actual needs, and the connecting member 333 may be maintained in a desired position, thereby fixing the rotating disk 310 in a desired position, and thus allowing the lamp holder 100 to remain in that position after being rotated to a desired angle.

[0079] In one embodiment, as shown in FIG18 , the limiting protrusion 3361 can have a trapezoidal structure, and the cross-sectional area of ​​the limiting protrusion 3361 gradually decreases as it approaches the connecting member 333. And / or, as shown in FIG16 , the limiting groove 3334 can have a trapezoidal structure, and the cross-sectional area of ​​the limiting groove 3334 gradually increases as it approaches the limiting member 336. In this way, compared to the embodiment described below in which the limiting protrusion 3361 has a square structure and / or the limiting groove 3334 is a square groove, the limiting protrusion 3361 can easily slide out of the limiting groove 3334 when the rotating arm 320 is rotated, which helps save effort when rotating the rotating arm 320 or the rotating disk 310.

[0080] In an optional embodiment, the first edge of the limiting protrusion 3361 may be provided with a first guide surface, and the second edge of the limiting protrusion 3361 may be provided with a second guide surface, and the distance between the first guide surface and the second guide surface gradually decreases in the direction approaching the connecting member 333, and / or, a third guide surface and a fourth guide surface may be provided on the groove wall of the limiting groove 3334, and the distance between the third guide surface and the fourth guide surface gradually increases in the direction approaching the limiting member 336.

[0081] In other embodiments, the limiting protrusion 3361 may be a square structure, and / or the limiting groove 3334 may be a square groove.

[0082] Based on the rotating device 300 disclosed in this application, an embodiment of the present application further provides a lamp, as shown in Figures 4 and 5, which may include a lamp base 100, a support 200, and a rotating device 300 as described in any of the above embodiments. The lamp base 100 may be connected to the rotating disk 310 of the rotating device 300, and the rotating arm 320 of the rotating device 300 may be connected to the support 200.

[0083] The beneficial effects achieved by the lamp provided in the embodiment of the present application are consistent with the beneficial effects achieved by the rotating device 300 provided in the embodiment of the present application, and will not be repeated here.

[0084] In one embodiment, the support 200 can be connected to a base mounting surface, for example, the support 200 can be connected to a ceiling. Furthermore, a power supply unit can be disposed within the support 200, and the power supply unit can be used to electrically and mechanically connect to an external power source. A wire 400 connected to the power supply unit can pass through a wire hole 327 on the rotating arm 320, extend into the lamp holder 100, and be electrically and mechanically connected to the light source.

[0085] Alternatively, the support 200 may be attached to a wall.

[0086] Here, the lamp may be a chandelier or a wall lamp, or other forms of lamps.

[0087] In one embodiment, as shown in FIG8 , the rotating arm 320 may include a first rotating arm 321 and a second rotating arm 322 connected to the first rotating arm 321. The first rotating arm 321 may be rotatably connected to the support 200, and the second rotating arm 322 may be rotatably connected to the rotating disk 310 via a first rotating shaft mechanism 330 and a second rotating shaft mechanism 340. Furthermore, the second rotating arm 322 is offset from the axis of the first rotating arm 321. Specifically, the angle between the second rotating arm 322 and the axis of the first rotating arm 321 is an acute angle or an obtuse angle. This helps reduce the axial space occupied by the rotating arm 320, thereby helping reduce the axial space occupied by the lamp. Furthermore, it helps increase the position adjustment range of the lamp head 100 to accommodate different types of lamps.

[0088] It should be noted that the axial direction in the axial space here refers to the axial direction of the support 200 .

[0089] The embodiments of the present application are described above in conjunction with the accompanying drawings, but the present application is not limited to the above-mentioned specific implementation methods. The above-mentioned specific implementation methods are merely illustrative and not restrictive. Under the guidance of this application, ordinary technicians in this field can also make many forms without departing from the purpose of this application and the scope of protection of the claims, all of which are within the protection of this application.
