[0040] The specific implementation of this application is described in more detail below in conjunction with specific embodiments:

[0041] Embodiment 1

[0042] Please also read Figures 1 to 6 The embodiment of the present application provides a lamp, including a lamp body 10 and a lamp holder 20 detachably mounted on the end of the lamp body 10. Based on this, it is convenient to achieve the purpose of having a lamp with different lighting effects by replacing different types of lamp holders 20, thereby greatly improving the application scenarios and usage performance of the lamp.

[0043] Among them, one of the lamp holder 20 and the lamp body 10 is provided with a concave first connecting component 21, and the other one is provided with a convex second connecting component 11 that can be inserted into the first connecting component 21, the first connecting component 21 is provided with a first locking structure 12, and the second connecting component 11 is provided with a second locking structure 22, and the second connecting component 11 can rotate relative to the first connecting component 21 until the second locking structure 22 is locked and matched with the first locking structure 12.

[0044] Based on this, the convex second connecting component 11 can be conveniently, quickly and efficiently controlled to be inserted into the concave first connecting component 21, and then the second connecting component 11 can be controlled to rotate relative to the first connecting component 21 until the second locking structure 22 and the first locking structure 12 are locked together, thereby completing the connection between the lamp holder 20 and the lamp body 10; conversely, the locking fit between the second locking structure 22 and the first locking structure 12 can be released by corresponding means, and then the convex second connecting component 11 can be controlled to be pulled out from the concave first connecting component 21, thereby realizing the detachability of the lamp holder 20 and the lamp body 10, which is convenient for disassembly and assembly, and convenient for replacing the lamp holder 20.

[0045] Based on this, the detachable connection between the lamp holder 20 and the lamp body 10 can be achieved by setting a convex second connecting component 11 to be inserted into the concave first connecting component 21 for rotation and locking, so that the stress of the connection between the lamp body 10 and the lamp holder 20 can be relatively evenly distributed on the entire first connecting component 21 and the entire second connecting component 11, so that the connection between the first connecting component 21 and the second connecting component 11 is more stable and reliable, that is, the connection between the lamp holder 20 and the lamp body 10 is more stable and reliable. Therefore, compared with the prior art that adopts the plug-in cooperation of locating pins and locating holes or the sliding cooperation of slide rails and slide grooves to achieve the detachable connection between the lamp holder 20 and the lamp body 10, the embodiment of the present application can obviously balance the stress between the lamp body 10 and the lamp holder 20, especially the gravity of the lamp holder 20, on the entire first connecting component 21 and the entire second connecting component 11, so as to reduce the risk of damage of the connection structure between the lamp body 10 and the lamp holder 20 due to stress concentration, greatly improve the connection stability and reliability between the lamp holder 20 and the lamp body 10, and greatly improve the performance of the lamp.

[0046] In summary, the lamp provided in the embodiment of the present application can conveniently, quickly and efficiently control the convex second connecting component 11 to be inserted into the concave first connecting component 21, and then control the second connecting component 11 to rotate relative to the first connecting component 21 until the second locking structure 22 is locked with the first locking structure 12, thereby completing the connection between the lamp holder 20 and the lamp body 10; conversely, the locking fit between the second locking structure 22 and the first locking structure 12 can be released by corresponding means, and then the convex second connecting component 11 can be controlled to be pulled out from the concave first connecting component 21, thereby realizing the detachability of the lamp holder 20 and the lamp body 10, which is convenient for disassembly and assembly, and facilitates the replacement of the lamp holder 20, thereby greatly improving the universal performance of the lamp, and the connection between the lamp holder 20 and the lamp body 10 is very stable and reliable, thereby greatly improving the performance of the lamp.

[0047] In addition, the lamp provided in the embodiment of the present application adopts a detachable connection between the lamp head 20 and the lamp body 10, which makes it convenient for users to achieve the purpose of lamps with different functions by replacing different lamp heads 20 as needed, greatly improving the universal performance of the lamp, and can effectively reduce the situation where users need to carry a variety of camera lamps when going out for shooting, which is inconvenient to carry; in addition, it can also effectively reduce the number of lamps with different functions purchased by users, and reduce the cost of purchasing lamps for users; in addition, the lamp head 20 and the lamp body 10 adopt a rotating detachable connection method, which makes it convenient to design the lamp body 10 into a cylinder, and then to install related lighting effect tools toward the cylindrical lamp body 10, further improving the application scenarios and usage performance of the lamp.

[0048] See also Figure 2 , Figure 3 In this embodiment, at least one rotating ear 111 is convexly provided on the circumferential side of the second connecting component 11, and an insertion portion 211 for inserting the rotating ear 111 is provided on the inner circumference of the first connecting component 21, and a rotating groove 222 extending along the circumferential direction and communicating with the insertion portion 211. The rotating ear 111 can slide into the rotating groove 222 from the insertion portion 211, and the rotating ear 111 moves in the rotating groove 222 when the second connecting component 11 rotates relative to the first connecting component 21.

[0049] By adopting the above scheme, when the rotating ear 111 of the second connecting component 11 is opposite to the insertion part 211 of the first connecting component 21, the second connecting component 11 is controlled to be inserted into the first connecting component 21, and at the same time, the rotating ear 111 is inserted into the insertion part 211; then, the second connecting component 11 is controlled to rotate relative to the first connecting component 21, and at the same time, the rotating ear 111 slides smoothly into the rotating groove 222 under the guidance of the insertion part 211, and moves in the rotating groove 222 until the second locking structure 22 is locked with the first locking structure 12, and the connection between the lamp holder 20 and the lamp body 10 is completed. In this way, under the joint action of the locking cooperation between the second locking structure 22 and the first locking structure 12 and the limiting effect of the rotating ear 111 by the rotating groove 222, the lamp holder 20 and the lamp body 10 are more stable in the locked state, and the connection between the lamp holder 20 and the lamp body 10 is more stable and reliable, further improving the performance of the lamp. On the contrary, by corresponding means, the locking fit between the second locking structure 22 and the first locking structure 12 is released, and then the second connecting component 11 is controlled to rotate relative to the first connecting component 21, and the rotating ear 111 is aligned with the insertion portion 211, and then the second connecting component 11 is controlled to be pulled out from the first connecting component 21, so that the lamp holder 20 and the lamp body 10 can be detachable.

[0050] See also Figure 5 , Figure 6In this embodiment, the inner circumferential wall of the first connecting component 21 is provided with a plurality of arc-shaped protrusions 223 spaced apart along the circumferential direction. Each protrusion 223 is spaced apart from the bottom wall of the first connecting component 21 and encloses a rotating groove 222, and an insertion portion 211 is formed between adjacent protrusions 223.

[0051] By adopting the above scheme, the rotation groove 222 can be formed by enclosing each convex edge 223 and the bottom wall of the first connecting component 21, and the insertion portion 211 can be formed between adjacent convex edges 223. In this way, the formation of the rotation groove 222 and the insertion portion 211 is very simple, and it is easy to achieve the connection between the insertion portion 211 and the rotation groove 222. The structure of the first connecting component 21 is very simple, which can effectively reduce the design and production costs of the lamp.

[0052] Of course, in other possible implementations, the insertion portion 211 and the rotation groove 222 may be groove-shaped structures directly opened on the inner circumferential wall of the first connecting component 21 , and this embodiment does not limit this.

[0053] Please also read Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 In this embodiment, a first elastic member 224 is provided on one side of the protruding edge 223 facing the bottom wall of the first connecting component 21 , and the first elastic member 224 is used to elastically resist the rotating ear 111 sliding into the rotating groove 222 .

[0054] By adopting the above scheme, when the lamp holder 20 and the lamp body 10 are in a locked state, the first elastic member 224 can elastically support the rotating ear 111 between it and the bottom wall of the first connecting component 21, so as to stabilize the position of the rotating ear 111, especially limit the axial movement of the rotating ear 111 in the first connecting component 21, thereby effectively ensuring the limiting effect of the rotating groove 222 on the rotating ear 111, making the lamp holder 20 and the lamp body 10 more stable in the locked state, further improving the stability and reliability of the connection between the lamp holder 20 and the lamp body 10, and further improving the performance of the lamp.

[0055] Please also refer to 2. Figure 3 , Figure 4 , Figure 5 , Figure 6 In this embodiment, the second connecting component 11 is formed with a slideway 112 on one side of each rotating ear 111 for each flange 223 to slide therein, and a limiting column 113 is provided on the slideway 112, and the limiting column 113 is used to cooperate with any flange 223 to stop.

[0056] By adopting the above scheme, the second connecting component 11 is controlled to rotate relative to the first connecting component 21 until the second locking structure 22 is locked and matched with the first locking structure 12. At this time, the limit column 113 can stop one of the protruding edges 223 to locate the rotation position of the second connecting component 11 relative to the first connecting component 21. In this way, the operator can be promptly and effectively reminded that the connection between the first connecting component 21 and the first connecting component 21 has been completed, and the operator is prevented from further controlling the second connecting component 11 to rotate relative to the first connecting component 21, thereby effectively reducing the risk of the second connecting component 11 and the first connecting component 21 being too tightly connected and inconvenient to disassemble due to excessive force applied by the operator, or even causing damage to the second locking structure 22 and the first locking structure 12, thereby further ensuring and improving the performance of the lamp.

[0057] Please refer to 2. Figure 3 , Figure 4 , Figure 5 , Figure 6 In this embodiment, one of the first locking structure 12 and the second locking structure 22 is a locking column, and the other one of the two is a locking hole. The locking column can be limited in the locking hole to limit the relative rotation of the first connecting component 21 and the second connecting component 11; the inner end of the locking column is provided with a second elastic member 13 that elastically resists it, and the locking column is connected to an unlocking push button 14, which can drive the locking column to move in a direction close to the second elastic member 13 to release the cooperation between the locking column and the locking hole.

[0058] By adopting the above scheme, by controlling the second connecting component 11 to be inserted into the first connecting component 21, and controlling the second connecting component 11 to rotate relative to the first connecting component 21, when the locking column is rotated to be opposite to the locking hole, the locking column is timely and automatically extended into the locking hole under the elastic force of the second elastic member 13 and is limited in the locking hole, so as to realize the locking cooperation between the second locking structure 22 and the first locking structure 12, and the connection between the lamp holder 20 and the lamp body 10 can be completed; conversely, by controlling the unlocking push button 14 to drive the locking column along the direction close to the second elastic member 13, The second connecting component 11 is controlled to rotate relative to the first connecting component 21 to dislocate the locking column and the locking hole, and the rotating ear 111 is aligned with the insertion portion 211. The second connecting component 11 is controlled to be pulled out from the first connecting component 21, so that the lamp holder 20 and the lamp body 10 can be detachable. In this way, the operation of realizing and canceling the locking cooperation between the second locking structure 22 and the first locking structure 12 is very convenient and easy, which further improves the performance of the lamp and provides a good user experience.

[0059] Please also read Figure 2 , Figure 3 , Figure 5 , Figure 6 In this embodiment, the first connecting component 21 is provided with at least one first connector 225, and the second connecting component 11 is provided with at least one second connector 114. The first connector 225 and the second connector 114 are aligned and electrically connected when the second locking structure 22 is locked with the first locking structure 12.

[0060] By adopting the above scheme, while completing the mechanical connection between the first connecting component 21 and the second connecting component 11, the electrical connection between the first connector 225 and the second connector 114 can also be completed. That is, while completing the mechanical connection between the lamp holder 20 and the lamp body 10, the electrical connection between the lamp holder 20 and the lamp body 10 can also be completed. Therefore, while ensuring the performance of the lamp, the assembly process of the lamp holder 20 and the lamp body 10 can be effectively simplified, and the production cost of the lamp can be effectively reduced.

[0061] Specifically, the lamp body 10 also includes a lamp body circuit board 17 installed inside its lamp body shell 16, and the lamp holder 20 also includes a lamp holder circuit board 26 installed inside its lamp holder body 23. The lamp body circuit board 17 and the lamp holder circuit board 26 are electrically connected via a first connector 225 and a second connector 114. In this way, after receiving a control signal from the lamp holder circuit board 26, the lamp holder circuit board 26 can be triggered to realize functions such as lighting of the lamp holder 20, so as to realize the performance of the lamp.

[0062] Please see also Figure 2 , Figure 3 , Figure 5 , Figure 6 In this embodiment, the first connector 225 is a probe and the second connector 114 is a contact.

[0063] In a possible embodiment, the contact is arranged at the center of the second connecting component 11. In this way, when the second connecting component 11 is inserted into the first connecting component 21 and rotated relative to the first connecting component, it can be ensured that the first connector 225 is always opposite to the second connector 114. In this way, it can be ensured that when the second connecting component 11 and the first connecting component 21 complete the mechanical connection, the first connector 225 and the second connector 114 complete the electrical connection, thereby effectively ensuring the performance of the lamp.

[0064] In another possible embodiment, the end face of the second connecting component 11 is provided with an arc groove 115 extending in the circumferential direction, and one end of the arc groove 115 is provided with a contact arranged at a distance from the center of the second connecting component 11, and the arc groove 115 is used for the probe to slide therein. Based on this, the arc groove 115 is used to limit the probe sliding therein, and when the second connecting component 11 is inserted toward the first connecting component 21 and rotates relative to the first connecting member, it can effectively ensure that the probe slides along the arc groove 115 and toward the contact, greatly reducing the risk of the probe deviating from the contact and failing to achieve electrical connection, which is conducive to ensuring that when the second connecting component 11 and the first connecting component 21 complete the mechanical connection, the probe is electrically connected to the contact in the arc groove 115, effectively ensuring the performance of the lamp.

[0065] In another possible embodiment, the end face of the second connecting component 11 is provided with an arc strip 116 extending along the circumferential direction, the arc strip 116 is provided with a plurality of contacts along its extension direction, the arc strip 116 has a protrusion 1161, and the end face of the first connecting component 21 is provided with a limiting groove 226 for limiting the protrusion 1161 therein. At the same time, the end face of the first connecting component 21 is also provided with an arc structure similar to the arc strip 116, and a plurality of probes are correspondingly arranged on the arc structure. Based on this, when the second connecting component 11 is inserted toward the first connecting component 21 and rotated relative to the first connecting component 21, the protrusion 1161 of the arc strip 116 is synchronously limited in the limiting groove 226 and moves along the limiting groove 226, and when the second connecting component 11 and the first connecting component 21 are locked, the protrusion 1161 can be limited in the limiting groove 226, so that each probe and each contact can be accurately and stably aligned and electrically connected. That is, it is more conducive to ensuring that when the second connecting component 11 and the first connecting component 21 complete the mechanical connection, the probe in the limiting groove 226 and the contacts of the arc strip 116 are more accurately and stably electrically connected, so as to more effectively ensure the performance of the lamp.

[0066] The above three implementation modes can be configured in a compatible manner, or one or both of them can be selected for configuration.

[0067] See also Figure 1 , Figure 4 In this embodiment, an installation cavity 15 for installing a battery 18 is recessed on the outer side of the lamp body 10, and the installation cavity 15 is provided with an opening on at least one side thereof in the circumferential direction.

[0068] By adopting the above solution, by installing the battery 18 in an open-designed installation cavity 15, the purpose of increasing the volume of the battery 18 can be achieved from several directions, so that the installation of the battery 18 is not limited by the space of the lamp body 10, which greatly improves the expandability of the battery 18 capacity, increases the application scenarios of the lamp, and effectively improves the performance of the lamp.

[0069] Specifically, the battery 18 installed in the installation cavity 15 is electrically connected to the lamp body circuit board 17 to achieve the purpose of the battery 18 supplying power to the lamp body circuit board 17, thereby achieving the performance of the lamp; of course, in other possible implementations, the lamp body circuit board 17 can also be electrically connected to an external power supply to achieve the purpose of the external power supply supplying power to the lamp body circuit board 17, thereby achieving the performance of the lamp.
