[0034] The following will be combined with the drawings in the embodiments of the present application to clearly describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments in the present application belong to the scope of protection of this application.

It should be understood that the data used in this way can be interchangeable under appropriate circumstances, so that the embodiments of the present application can be implemented in an order other than those illustrated or described here, and the objects distinguished by "first", "second", etc. are generally of one type, and the number of objects is not limited. For example, the first object can be one or more. In addition, "and / or" in the specification and claims represents at least one of the connected objects, and the character " / " generally indicates that the objects associated with each other are in an "or" relationship.

[0036] The rotating structure for a lamp and the lamp provided in the embodiment of the present application are described in detail below with reference to the accompanying drawings through specific embodiments and their application scenarios.

[0037] Please refer to Figure 1-Figure 14 The present application discloses a rotating structure for a lamp, which is used to connect a lamp body 120 and a lamp holder 110 of the lamp. Specifically, the rotating structure includes: a first connecting member 200, a second connecting member 300 and a rotating shaft 400.

[0038] One of the first connector 200 and the second connector 300 is used to connect to the lamp body 120, and the other is used to connect to the lamp holder 110. Specifically, for example, Fig.13 and Fig.14 As shown, when in use, the first connecting member 200 is connected to the lamp holder 110 , and the second connecting member 300 is connected to the lamp body 120 .

[0039] The first end of the rotating shaft 400 is rotatably connected to the first connecting member 200 around a first axis, and the second end of the rotating shaft 400 is rotatably connected to the second connecting member 300 around a second axis, and the first axis intersects or is not in the same plane as the second axis. Specifically, the first axis intersects the second axis, for example, the first axis is perpendicular to the second axis.

[0040] The rotating structure for the lamp provided in the embodiment of the present application is used by connecting the first connecting member 200 to the lamp body 120, and connecting the second connecting member 300 to the lamp holder 110, or connecting the first connecting member 200 to the lamp holder 110, and connecting the first connecting member 200 to the lamp body 120. Since the first end of the rotating shaft 400 is connected to the first connecting member 200 for rotation around the first axis, and the second end is connected to the second connecting member 300 for rotation around the second axis, and the first axis intersects or is not in the same plane as the second axis, the lamp holder 110 can rotate around the first axis and around the second axis, and the lamp holder 110 can rotate in at least two directions, so that the lamp is more convenient to use and can bring more experience to the user.

[0041] In another embodiment, if Figure 3 and Figure 5 As shown, the rotating structure further includes a first locking member 500, which is, for example, a nut. A first limiting step 410 is provided at the first end of the rotating shaft 400, and the first connecting member 200 is rotatably sleeved on the rotating shaft 400 and abuts against the first limiting step 410. The first locking member 500 is sleeved on the first end of the rotating shaft 400 and is threadedly connected to the rotating shaft 400, and a side of the first connecting member 200 that is away from the first limiting step 410 abuts against the first locking member 500. With such a configuration, the first locking member 500 is loosened and removed from the rotating shaft 400, and the first connecting member 200 can be disassembled and assembled. The first connecting member 200 is easy to replace, and the pre-tightening force applied by the first locking member 500 to the first connecting member 200 can be adjusted by rotating the first locking member 500. The greater the pre-tightening force, the greater the force required for the user to rotate the lamp head 110. Conversely, the smaller the pre-tightening force, the smaller the force required for the user to rotate the lamp head 110. In this way, the pre-tightening force can be adjusted according to user needs, thereby providing a better user experience.

[0042] In other embodiments, the first connecting member 200 may be sleeved on the rotating shaft 400 by means of interference fit, or may be directly connected to the rotating shaft 400 by means of snap-fit.

[0043] In another embodiment, if Figure 3 As shown, one of the rotating shaft 400 and the first connecting member 200 is provided with a first positioning portion 210, and the other is provided with a first limiting groove 420a along the circumference of the rotating shaft 400, the first positioning portion 210 is slidably matched with the first limiting groove 420a, and the two opposite side walls of the first limiting groove 420a in the circumference of the rotating shaft 400 can respectively abut against the first positioning portion 210. In this way, the relative rotation angle of the first connecting member 200 and the rotating shaft 400 can be limited by the cooperation of the first limiting groove 420a and the first positioning portion 210, and then the relative rotation angle of the lamp holder 110 and the lamp body 120 can be limited, so that the lamp holder 110 can rotate within a preset first angle range, avoiding interference between the lamp holder 110 and other components.

[0044] In other embodiments, the first positioning portion 210 and the first limiting groove 420 a may not be provided. In this case, the lamp holder 110 and the lamp body 120 may rotate 360 ​​degrees around the first axis, that is, the axis of the rotating shaft 400 .

[0045] Specifically, for example, a first positioning portion 210 is provided on the first connecting member 200, and a first limiting groove 420a is provided on the rotating shaft 400 along the circumference of the rotating shaft 400. More specifically, for example, Figure 3 As shown, the first end of the rotating shaft 400 protrudes radially outward to form a protrusion 420, and one side of the protrusion 420 is a first limiting step 410. The protrusion 420 is provided with the above-mentioned first limiting groove 420a along the circumference of the protrusion 420, and the first positioning portion 210 is provided on the side of the first connecting member 200 facing the protrusion 420. In this way, the first limiting step 410 and the first limiting groove 420a are both provided on the protrusion 420, and the protrusion 420 not only plays the role of axially positioning the first connecting member 200, but also limits the relative rotation angle between the first connecting member 200 and the rotating shaft 400, so that the rotating structure is more compact as a whole and has a smaller volume. Of course, in other embodiments, the first limiting step 410 and the first limiting groove 420a can also be respectively provided on the opposite sides of the first connecting member 200, and respectively provided on different parts of the rotating shaft 400.

[0046] Furthermore, if Figure 3As shown, the rotating structure further includes a first disc washer 600, which is sleeved on the first end of the rotating shaft 400, and is located between the first locking member 500 and the first connecting member 200, and is against the first locking member 500 and the first connecting member 200. The first disc washer 600 has good anti-loosening and anti-vibration performance. By adding the first disc washer 600 between the first locking member 500 and the first connecting member 200, the connection stability of the first locking member 500 can be improved, the loosening risk of the first locking member 500 can be reduced, and it is also beneficial to maintain the angle between the first connecting member 200 and the rotating shaft 400.

[0047] In other embodiments, the first disc washer 600 may not be provided, and the first locking member 500 directly abuts against the first connecting member 200 .

[0048] In another embodiment, if Figure 1 and Figure 4 As shown, the rotating structure further includes a threaded connector 700 and a second locking member 800. The second end of the threaded connector 700 passes through the rotating shaft 400 and the second connecting member 300 and is threadedly connected with the second locking member 800. The axis of the threaded connector 700 may be, for example, perpendicular to the axis of the rotating shaft 400. The rotating shaft 400 and the second connecting member 300 are both located between the first end of the threaded connector 700 and the second locking member 800, and one of the rotating shaft 400 and the second connecting member 300 abuts against the first end of the threaded connector 700, and the other abuts against the second locking member 800. In this arrangement, the rotating shaft 400 and the second connecting member 300 can be separated by loosening the second locking member 800 and removing the second locking member 800, which makes it easy to disassemble and assemble the second connecting member 300. In addition, as above, rotating the second locking member 800 can adjust the size of the pre-tightening force applied to the second connecting member 300. The greater the pre-tightening force, the greater the force required for the user to rotate the lamp head 110. Conversely, the smaller the pre-tightening force, the smaller the force required for the user to rotate the lamp head 110. By setting it in this way, the size of the pre-tightening force can be adjusted according to user needs, which makes the user experience of the lamp better.

[0049] In other embodiments, the rotating structure may include a connecting column, which passes through the rotating shaft 400 and the second connecting member 300 and is interference-fitted with the rotating shaft 400 and the second connecting member 300 .

[0050] Furthermore, if Figure 4As shown, one of the rotating shaft 400 and the second connecting member 300 is provided with a second positioning portion 310, and the other is provided with a second limiting groove 440a along the circumference of the threaded connecting member 700, the second positioning portion 310 is slidably matched with the second limiting groove 440a, and the two opposite side walls of the second limiting groove 440a in the circumference of the threaded connecting member 700 can respectively abut against the second positioning portion 310. In this way, the relative rotation angle of the second connecting member 300 and the rotating shaft 400 can be limited by the relative cooperation of the second limiting groove 440a and the second positioning portion 310, thereby limiting the relative rotation angle of the lamp holder 110 and the lamp body 120, so that the lamp holder 110 can rotate within a preset second angle range, avoiding interference between the lamp holder 110 and other components.

[0051] In other embodiments, the second positioning portion 310 and the second limiting groove 440 a may not be provided. In this case, the lamp holder 110 and the lamp body 120 may rotate 360 ​​degrees around the second axis, that is, the axis of the threaded connector 700 .

[0052] Further, if Figure 4 As shown, the rotating structure further includes a second disc washer 900, which is sleeved on the threaded connector 700, and is located between the second locking member 800 and the second connector 300, and is against the second locking member 800 and the second connector 300. Like the first disc washer 600, the second disc washer 900 also has good anti-loosening and anti-vibration performance. By adding the second disc washer 900 between the second locking member 800 and the second connector 300, the connection stability of the second locking member 800 can be improved, the loosening risk of the second locking member 800 can be reduced, and it is also helpful to maintain the angle between the second connector 300 and the rotating shaft 400.

[0053] Furthermore, if Figure 5 As shown, the rotating shaft 400 includes: a shaft body 450 and a limiting sleeve 440. One end of the shaft body 450 is connected to the first connecting member 200, and the other end of the shaft body 450 is provided with a connecting portion 430, and the connecting portion 430 is provided with a receiving groove 430a. The second connecting member 300 is partially placed in the receiving groove 430a. The connecting portion 430 is provided with an opening, and the second end of the threaded connecting member 700 passes through the opening and the second connecting member 300 in sequence. The limiting sleeve 440 is sleeved on the threaded connecting member 700 and is located in the receiving groove 430a. The two ends of the limiting sleeve 440 are respectively against the bottom of the receiving groove 430a and the second connecting member 300. As shown in FIG. Figure 6 As shown, the outer wall of the threaded connector 700 is provided with a positioning surface 710, and the inner wall of the opening is provided with a first limiting surface. The positioning surface 710 is parallel to the first limiting surface and fits with it, so that the threaded connector 700 and the rotating shaft 400 are relatively fixed in the circumferential direction of the threaded connector 700; Figure 7As shown, the inner wall of the limiting sleeve 440 is provided with a second limiting surface 440b, and the positioning surface 710 is parallel to and fits with the second limiting surface 440b, so that the threaded connector 700 and the limiting sleeve 440 are relatively fixed in the circumferential direction of the threaded connector 700. In this way, the connection position of the rotating shaft 400 and the second connector 300 partially overlaps, which makes the thickness of the connection position of the rotating shaft 400 and the second connector 300 smaller, so that the required length of the threaded connector 700 is shorter, and the connection position of the rotating shaft 400 and the second connector 300 occupies less space, which can make the rotating structure more compact as a whole.

[0054] In other embodiments, the connection portion 430 of the rotating shaft 400 may not be provided with the receiving groove 430 a , and the second connection member 300 may be directly disposed on one side of the connection portion 430 .

[0055] Furthermore, refer to Figure 6 and Figure 7 As shown, the number of the positioning surfaces 710 is two, and the two positioning surfaces 710 are arranged in parallel and opposite to each other. Correspondingly, the number of the first limiting surface and the second limiting surface 440b are both two, and the first limiting surface corresponds to and fits with the positioning surface 710 one by one, and the second limiting surface 440b corresponds to and fits with the positioning surface 710 one by one. By increasing the number of the positioning surfaces 710, the first limiting surface, and the second limiting surface 440b, the resistance between the threaded connector 700 and the limiting sleeve 440 and the connecting portion 430 can be increased, thereby making it more difficult for the limiting sleeve 440 and the connecting portion 430 to rotate relative to the threaded connector 700. In other embodiments, the positioning surfaces 710, the first limiting surface, and the second limiting surface 440b can also be other numbers of more than two, which can be set according to actual needs.

[0056] More specifically, the second connecting member 300 is, for example, a connecting sheet.

[0057] Furthermore, if Figure 5 As shown, the cross-sectional area of ​​the connecting portion 430 is larger than the cross-sectional area of ​​the shaft body 450, the thickness of the portion of the connecting portion 430 where the receiving groove 430a is provided is smaller than the cross-sectional size of the shaft body 450, and a threading hole 430b is provided on the connecting portion 430, and the wire inside the lamp passes through the threading hole 430b to achieve its own positioning. In this way, there is no need to add threading holes 430b at other positions of the lamp, and the lamp as a whole is more compact and has a more convenient layout.

[0058] Furthermore, the protrusion 420 in the above embodiment is disposed on the shaft 450 .

[0059] refer to Figure 8-Figure 14As shown, the present application also discloses a lamp, comprising a lamp body 120, a lamp holder 110 and the aforementioned rotating structure, wherein one of the first connecting member 200 and the second connecting member 300 is connected to the lamp body 120, and the other is connected to the lamp holder 110. Fig.13 and Fig.14 As shown, the first connecting member 200 is connected to the lamp holder 110 , and the second connecting member 300 is connected to the lamp body 120 .

[0060] Furthermore, the number of lamp holders 110, first connectors 200 and rotating shafts 400 are at least two, the lamp holders 110 and first connectors 200 correspond to each other and are connected, the first connectors 200 and rotating shafts 400 correspond to each other, each first connector 200 is rotatably connected to the same second connector 300 through the corresponding rotating shafts 400, the second connector 300 is connected to the lamp body 120, and the second axes of each rotating shaft 400 are parallel. In this way, at least two first connectors 200 and rotating shafts 400 share one second connector 300, at least two lamp holders 110 are connected to the same lamp body 120, and there is no need to set the number of second connectors 300 and lamp holders 110 to be multiple, which can better save materials, reduce costs, and reduce the size of the lamp. Of course, in other embodiments, the lamp holder 110, the first connecting member 200, the rotating shaft 400, the second connecting member 300 and the lamp body 120 can be in a one-to-one correspondence. In this case, when the number of the lamp holder 110, the first connecting member 200 and the rotating shaft 400 are at least two, the number of the lamp body 120 and the second connecting member 300 also needs to be at least two.

[0061] Further, one of the first connector 200 and the second connector 300 is detachably connected to the lamp body 120, and the other is detachably connected to the lamp holder 110. Specifically, for example, screw connection can be used to achieve detachable connection. Of course, in other embodiments, one of the first connector 200 and the second connector 300 is connected to the lamp body 120 by gluing or welding, and the other is connected to the lamp body 120 by gluing or welding.

[0062] Furthermore, if Fig.13 and Fig.14 As shown, the lamp further includes a lamp pole 130 and a lamp holder 140, and the lamp body 120, the lamp pole 130 and the lamp holder 140 are connected in sequence.

[0063] As a specific implementation method, refer to Figure 10-Figure 14As shown, the lamp includes two lamp holders 110, and there are two lamp holders 110, two first connecting members 200, and two rotating shafts 400. The lamp holders 110 and the first connecting members 200 correspond to each other and are connected. The first connecting members 200 and the rotating shafts 400 correspond to each other. Each first connecting member 200 is rotatably connected to the same second connecting member 300 through its corresponding rotating shaft 400, and the second connecting member is connected to the lamp body 120. One of the lamp holders can rotate around at least one of the first axis and the second axis, and the other lamp holder can rotate around at least one of the third axis and the fourth axis. The third axis is parallel to the first axis, and the second axis is parallel to the fourth axis. When in use, Fig.10 As shown, the two lamp heads 110 can be rotated around the first axis and the third axis respectively, or as shown in Fig.11 and 12 As shown, the two lamp heads 110 can be rotated around the second axis and the fourth axis respectively, or one of the two lamp heads 110 can be rotated around the first axis or the third axis, and the other can be rotated around the second axis or the fourth axis. It should be noted that Figure 10-Figure 14 The direction indicated by the middle arrow is the rotation direction of the lamp holder 110 .

[0064] Furthermore, the lamp body 120 is provided with at least one of a light source module, a speaker module and a control module. More specifically, the light source module is, for example, an LED lamp, the speaker module is, for example, a speaker, and the control module is, for example, a control circuit board. With such a configuration, there is no need to add other components to install at least one of the light source module, the speaker module and the control module, which can make the lamp more compact as a whole, simpler in structure and lower in cost. In addition, by integrating at least one of the light source module, the speaker module and the control module into the lamp body 120, the functions of the lamp body 120 can be made more diverse, which can better meet the needs of users.

[0065] 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 the present application, ordinary technicians in this field can also make many forms without departing from the purpose of the present application and the scope of protection of the claims, all of which are within the protection of the present application.
