[0049] The technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only some of the embodiments of the present application, but not all the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the scope of protection of the present application.

[0050] It should be noted that, in the description of the present application, if the terms “first”, “second”, etc. appear, “first”, “second” are only used for convenient description of different components or names, and cannot be understood as indicating or implying the order relationship, relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features with “first”, “second” can explicitly or implicitly include at least one of the features. In addition, if “and / or” appears throughout the text, it means that it includes three parallel schemes, for example, “A and / or B” includes A scheme, or B scheme, or A and B schemes are satisfied at the same time.

[0051] ​​​​​In order to realize the quick disassembly of the lamp body and the adapter, the disassembly structure is usually simple, which makes the user easy to touch by mistake and the children more likely to disassemble, for example, the children press or push some switch elements on the lamp body at will, and the lamp body can be separated from the adapter. At the moment when the lamp body and the adapter are separated, if the lamp body is not supported in time, the lamp body will fall to the ground and be damaged, and it is also easy to hit the user and cause safety hazards.

[0052] In view of this, the lamp body connection structure provided by the embodiments of the present application can realize the quick disassembly of the adapter and the lamp body, and can avoid the lamp body from falling easily and being damaged and reduce the safety risk.

[0053] Please refer to Figure 1 , Figure 5 , Figure 7 , Figure 10 and Figure 13 , the lamp body connection structure provided by the embodiments of the present application comprises an adapter 10 and a lamp body 20, one of the adapter 10 and the lamp body 20 is provided with a first electrical connector 31, and the other is provided with a second electrical connector 32 connected with the first electrical connector 31; the adapter 10 is provided with a first magnetic attraction member 33 and a first clamping structure (not marked), the lamp body 20 is provided with a second magnetic attraction member 34 and a second clamping structure 50, the first magnetic attraction member 33 is magnetically connected with the second magnetic attraction member 34, and the first clamping structure is clamped with the second clamping structure 50.

[0054] When the adapter 10 and the lamp body 20 are aligned, the first magnetic attraction member 33 and the second magnetic attraction member 34 are attracted together, so that the adapter 10 and the lamp body 20 are pre-installed, at this time, the lamp body 20 can be prevented from falling easily, which is beneficial to the subsequent operation of the lamp body 20. Then the first clamping structure and the second clamping structure 50 are clamped, so that the lamp body 20 is completely fixed to the adapter 10, at this time, the first electrical connector 31 and the second electrical connector 32 also realize electrical connection. When the adapter 10 is connected to the power supply through the power supply line, the power supply and the conductive connection of the first electrical connector 31 and the second electrical connector 32 can supply power to the electronic elements inside the lamp body 20.

[0055] When the lamp body 20 needs to be disassembled, the first clamping structure and the second clamping structure 50 are first separated, at this time, due to the attraction of the first magnetic attraction member 33 and the second magnetic attraction member 34, the lamp body 20 is still attached to the adapter 10, even if it is not supported by the hand, the lamp body 20 will not fall, only when a larger pulling force is applied, the lamp body 20 will be separated from the adapter 10. In this way, by using the first magnetic attraction member 33 and the second magnetic attraction member 34, the lamp body 20 can be prevented from falling easily during disassembly, thereby reducing the safety risk and avoiding the lamp body 20 from hitting the user.

[0056] In some embodiments, the adapter 10 is provided with a plurality of first magnetic members 33, and the lamp body 20 is correspondingly provided with a plurality of second magnetic members 34. The polarity of at least two first magnetic members 33 is opposite. In a specific embodiment, the adapter 10 is in the shape of a flat disc, and is provided with four first magnetic members 33. The four first magnetic members 33 are distributed on the same base circle, the center of the base circle coincides with the axis of the adapter 10, each two first magnetic members 33 form a group, and the two groups of magnetic members are centrally symmetrically arranged with the axis of the adapter 10 as the center. The distance between the two first magnetic members 33 in the same group is small, and the central angle of the two is less than 90°. The polarity of the two first magnetic members 33 in the same group can be the same, and the polarity of the first magnetic members 33 in different groups is opposite. In this way, by setting the polarity to be different, using the principle that same poles repel and opposite poles attract, only when the orientation of the lamp body 20 is correctly placed, the lamp body 20 can be attracted to the adapter 10, thereby achieving the effect of preventing mistakes. The purpose of providing a plurality of first magnetic members 33 and a plurality of second magnetic members 34 is to improve the adsorption force.

[0057] Please refer to Figure 9 , Figure 11 and Figure 13 In some embodiments, a first mounting cavity 10a is formed inside the adapter 10, and the first magnetic member 33 is embedded in the first mounting cavity 10a. Specifically, the adapter 10 includes a first shell 11 and a second shell 12, and the first shell 11 and the second shell 12 jointly form a receiving cavity 121. The inner wall of the first shell 11 or the second shell 12 is provided with an annular rib, and the space enclosed by the annular rib is the first mounting cavity 10a. The first mounting cavity 10a is a circular cavity, and therefore the first magnetic member 33 is also circular. The first magnetic member 33 and the annular rib can be in interference fit or glued. The annular rib not only realizes the installation of the first magnetic member 33, but also plays a role in strengthening the structure of the adapter 10. Furthermore, the first magnetic member 33 is hidden inside the adapter 10, which can avoid being exposed.

[0058] Please refer to Figure 6 , Figure 7 and Figure 8In some embodiments, the lamp body 20 is internally formed with a second mounting cavity 20a, and the second magnetic attraction member 34 is embedded in the second mounting cavity 20a. Specifically, the lamp body 20 includes an outer shell 21 and an insulating shell 22. The outer shell 21 is internally provided with a circuit board 60, and the insulating shell 22 is arranged on the circuit board 60 to cover the electronic components on the circuit board 60 and serve as an insulating protection. The side of the insulating shell 22 away from the circuit board 60 is formed with a concave cavity 221, and the inner wall of the outer shell 21 is provided with an annular protrusion 211. The space enclosed by the annular protrusion 211 and the concave cavity 221 opposite to each other jointly form a second mounting cavity 20a. Therefore, the second magnetic attraction member 34 is isolated from the electronic components by the insulating shell 22, and the influence on the electronic components can be avoided. Of course, in other embodiments, the second mounting cavity 20a can be formed by only the insulating shell 22 or the outer shell 21.

[0059] To realize the clamping of the lamp body 20 and the adapter 10, the specific structure has various forms. For example, the first clamping structure and the second clamping structure 50 are both clamping protrusions 41, and the two are clamped with each other. Alternatively, the first clamping structure is a groove, such as an L-shaped groove, and the second clamping structure 50 is a protrusion. First, the lamp body 20 is moved along the axial direction of the adapter 10, so that the second clamping structure 50 slides into a part of the L-shaped groove. Then, the lamp body 20 is rotated along the circumferential direction of the adapter 10, so that the second clamping structure 50 is turned to enter another part of the L-shaped groove.

[0060] For reference Figure 13 In some embodiments, the first clamping structure is provided with the clamping protrusion 41 and the handle portion 42, and the handle portion 42 is exposed outside the adapter 10. The second clamping structure 50 is a clamping groove or a clamping hole, and the first clamping structure can be translated relative to the adapter 10 under the action of an external force to be clamped with or separated from the second clamping structure 50. Specifically, by applying an external force on the handle portion 42, the first clamping structure is pushed to translate, so that the first clamping structure is separated from the second clamping structure 50. Conversely, when the handle portion 42 is subjected to an external force in the opposite direction, the first clamping structure translates in the opposite direction until the first clamping structure is clamped with the second clamping structure 50. Of course, to make the first clamping structure clamped with the second clamping structure 50, a spring return member 46 can also be provided to achieve this purpose.

[0061] Specifically, the first clamping structure includes the spring return member 46, one end of the spring return member 46 is fixed relative to the clamping protrusion 41, and the other end of the spring return member 46 is connected to the adapter 10. The clamping protrusion 41 can be translated to be clamped with the second clamping structure 50 under the action of the spring return member 46. When the first clamping structure and the second clamping structure 50 are separated from each other, the spring return member 46 is compressed. When the external force acting on the handle portion 42 disappears, the spring return member 46 restores the elastic deformation and pushes the first clamping structure to reset. The spring return member 46 can be a spring or a spring sheet.

[0062] The first clamping structure achieving clamping or unclamping by translation is described in detail through two embodiments as follows:

[0063] Please refer to Figure 5 and Figure 13 In the first embodiment, the first clamping structure includes a driving member 43, a driven member 44 and a gear 45, the driving member 43 and the driven member 44 are respectively provided with sawtooth to mesh with the gear 45, and the driving member 43 and the driven member 44 are respectively provided with a clamping protrusion 41, and the lamp body 20 is provided with a second clamping structure 50 corresponding to each clamping protrusion 41. The driving member 43 is translated to drive the gear 45 to rotate and in turn drive the driven member 44 to translate, so as to make the clamping protrusion 41 clamp or unclamp with the second clamping structure 50. Specifically, the driving member 43 is provided with a handle part 42, and the driving member 43, the gear 45 and the driven member 44 are basically sequentially arranged, so that the clamping protrusions 41 on the driving member 43 and the clamping protrusions 41 on the driven member 44 are basically distributed on two opposite sides of the adapter 10. The driving member 43 is pushed towards the driven member 44, the driving member 43 moves towards the driven member 44, and the gear 45 is driven to rotate, the driven member 44 moves towards the driving member 43 under the action of the gear 45, that is, the driving member 43 and the driven member 44 simultaneously move towards each other, and the clamping protrusions 41 of the two are retracted and withdrawn from the second clamping structure 50. In this way, one handle part 42 can realize linkage of multiple clamping protrusions 41, which facilitates overall control.

[0064] Further, in this embodiment, one or more elastic reset members 46 are respectively arranged between the driving member 43 and the adapter 10 and between the driven member 44 and the adapter 10, when the driving member 43 and the driven member 44 move towards each other, the elastic reset members 46 are compressed; when the external force applied on the handle part 42 is removed, the elastic reset members 46 push the driving member 43 and the driven member 44 outward, so that the driving member 43 and the driven member 44 move away from each other.

[0065] In order to avoid large deviation of the first clamping structure when moving, further, the adapter 10 can be provided with a guide protrusion, and the first clamping structure is provided with a guide hole 431 for the guide protrusion to insert, so that the first clamping structure can be translated in a direction perpendicular to the protruding direction of the guide protrusion. Specifically to this embodiment, as Figure 9 and Figure 11As shown, the adapter 10 comprises a first shell 11 and a second shell 12, which together form a receiving cavity 121 in which the first clamping structure is received. The adapter 10 is provided with an avoiding hole 122 corresponding to any one of the clamping protrusions 41, and the clamping protrusion 41 can enter and exit the avoiding hole 122. The first shell 11 is provided with a first annular protrusion 123, and the second shell 12 is provided with a second annular protrusion 124. The first annular protrusion 123 is insertedly matched with the second annular protrusion 124, so that the first annular protrusion 123 and the second protrusion combine to form a guide protrusion. The driving member 43 is provided with a guide hole 431 for the first annular protrusion 123 and the second annular protrusion 124 to be inserted, and the driving member 43 can be translated in a direction perpendicular to the protruding direction of the first annular protrusion 123. That is, the driving member 43 is sleeved outside the first annular protrusion 123 and the second protrusion through the guide hole 431, and is simultaneously limited by the first shell 11 and the second shell 12 to avoid disengagement from the first annular protrusion 123 and the second protrusion.

[0066] In the embodiment, the first annular protrusion 123 and the second annular protrusion 124 have multiple functions: on the one hand, they provide guidance and limitation for the translation of the driving member 43; on the other hand, they play a positioning role for the assembly of the first shell 11 and the second shell 12; and on the other hand, they have a structural reinforcement effect for the first shell 11 and the second shell 12. As can be seen, the rotating member is not randomly provided with a protrusion to play a guiding function, but rather the structural features of the adapter 10 itself are comprehensively utilized, so that one structure has multiple functions, achieving rational utilization and facilitating structural simplification.

[0067] In order to better guide the movement of the first clamping structure, the adapter 10 can further be provided with some guide grooves 125, and at least part of the first clamping structure is arranged in the guide grooves 125 to translate along the guide grooves 125. Specifically, the adapter 10 is further provided with a plurality of reinforcing ribs 126, and the guide grooves 125 are formed between adjacent two reinforcing ribs 126. At least part of the first clamping structure is arranged in the guide grooves 125 to translate along the guide grooves 125. The reinforcing ribs 126 not only have a guiding effect, but also achieve structural reinforcement of the adapter 10.

[0068] Please refer to Figure 14 and Figure 15 In the second embodiment, the first clamping structure comprises a handle portion 42 and an elastic reset member 46. The handle portion 42 is connected with the clamping protrusion 41, and when an external force is applied to the handle portion 42, the clamping protrusion 41 can be pushed along with the handle portion 42. Optionally, the adapter 10 is provided with two first clamping structures, and the two first clamping structures are distributed on two opposite sides of the adapter 10. Each of the first clamping structures is provided with one handle portion 42.

[0069] Specifically, the adapter 10 comprises a main housing 13 and a rotating plate 14. The main housing 13 is formed with a receiving cavity 121, an avoiding hole 122 and a sliding hole 134. The first clamping structure is received in the receiving cavity 121. The clamping protrusion 41 can enter and exit the avoiding hole 122. The handle portion 42 protrudes out of the main housing 13 from the sliding hole 134. The rotating plate 14 is provided with an avoiding gap 141. The rotating plate 14 is rotationally matched with the main housing 13 to have a first state and a second state. In the first state, the avoiding gap 141 is opposite to the handle portion 42 (as shown in Figure 14 FIG. 2), and the handle portion 42 can be moved along the radial direction of the sliding hole 134 to enter the avoiding gap 141. In the second state, the avoiding gap 141 is away from the handle portion 42, and the side edge of the rotating plate 14 is in abutment with the handle portion 42.

[0070] In the embodiment, the main housing 13 has a first outer surface 133. The sliding hole 134 penetrates through the first outer surface 133. The rotating plate 14 is stacked with the first outer surface 133. In the first state, the avoiding gap 141 and the handle portion 42 are distributed on the same radial direction of the rotating plate 14. Therefore, when the handle portion 42 is pushed, it can enter the avoiding gap 141, so that the first clamping structure and the second clamping structure 50 are disengaged. In the second state, the avoiding gap 141 and the handle portion 42 are staggered along the circumferential direction of the rotating plate 14. The side edge of the rotating plate 14 can prevent the handle portion 42 from being pushed by abutting with the handle portion 42, so that the first clamping structure and the second clamping structure 50 are kept clamped.

[0071] The radial direction of the sliding hole 134 refers to the direction perpendicular to the penetrating direction of the sliding hole 134. In the embodiment, the radial direction of the sliding hole 134 is parallel to the plate surface of the rotating plate 14.

[0072] For the convenience of operation, the side of the rotating plate 14 away from the first outer surface 133 is provided with a convex rib 142, which can be held by the user.

[0073] Please refer to Figure 15 and Figure 16 for further details. Further, the main housing 13 is further provided with a guide hole 1311 extending in the rotation direction of the rotating plate 14 in an arc shape. The rotating plate 14 is provided with a guide protrusion 143 inserted into the guide hole 1311. When the rotating plate 14 rotates, the guide protrusion 143 can slide along the length direction of the guide hole 1311, so that the rotating plate 14 maintains stable rotation and avoids deviation during rotation. Further, when the guide protrusion 143 contacts with the hole wall of the end portion of the guide hole 1311, the guide protrusion 143 cannot continue to slide. At this time, the rotating plate 14 stops rotating, so that the guide hole 1311 and the guide protrusion 143 also function as a stroke limiter.

[0074] In some embodiments, the main housing 13 comprises a third housing 131 and a fourth housing 132, which together form the accommodating cavity 121, the third housing 131 is provided with a guide hole 1311 and a foolproof hole 1312, and the fourth housing 132 is provided with a foolproof protrusion 1321 which is inserted into the foolproof hole 1312. Optionally, the guide hole 1311 and the foolproof hole 1312 are in communication, i.e. the foolproof hole 1312 is located at one end of the length direction of the guide hole 1311. The hole diameter of the foolproof hole 1312 is greater than or smaller than that of the guide hole 1311, so that the two can be distinguished. The design of the foolproof protrusion 1321 and the foolproof hole 1312 can ensure the correct installation of the first housing 11 and the second housing 12.

[0075] For reference Figures 2 to 5 In some embodiments, the lamp body 20 is provided with a receiving groove 23, the groove wall of which is provided with a second clamping structure 50, and the adapter 10 is flat and is received in the receiving groove 23. Therefore, the protruding height of the adapter 10 outside can be reduced, so that the combination of the lamp body 20 and the adapter 10 is flat as a whole. Optionally, the outer surface of the lamp body 20 is further provided with a protruding edge 24 which surrounds the receiving groove 23.

[0076] In some embodiments, the lamp body 20 is generally flat, such as a flat cuboid, which has a relatively long length, a relatively narrow width, and a thickness much smaller than the width. The lamp body 20 has two outer sides which are distributed in the thickness direction and are opposite to each other, and the protruding edge 24 is arranged on one of the outer sides.

[0077] Optionally, the protruding edge 24 is circular, and the adapter 10 is also generally disc-shaped.

[0078] For reference Figures 10 to 12Further, the adapter 10 is provided with a first accommodating hole 16, and the side of the adapter 10 facing the lamp body 20 is provided with a protective shell 15, which is a plastic part and surrounds the first accommodating hole 16, and the first electric connector 31 is arranged in the first accommodating hole 16 and extends into the protective shell 15. In this embodiment, the first accommodating hole 16 penetrates through the adapter 10, so that the first electric connector 31 can be inserted from the outside into the adapter 10 and then pass through the adapter 10. Alternatively, the protective shell 15 protrudes outside the first electric connector 31, that is, the first electric connector 31 does not pass through the protective shell 15, so that the protective shell 15 can better protect the first electric connector 31. In this embodiment, the adapter 10 is a metal part, for example, an aluminum alloy, and specifically, the first shell 11 and the second shell 12 are metal parts, or the third shell 131 and the fourth shell 132 are metal parts, which are used as appearance parts and have greater strength. The protective shell 15 is an insulating part, which surrounds the first electric connector 31 to provide insulation protection for the first electric connector 31.

[0079] For reference Figures 5 to 8 In some embodiments, the lamp body 20 includes a shell 21 and an insulating shell 22, the shell 21 is provided with a second accommodating hole 25, and the insulating shell 22 is located in the shell 21 and has an insulating protrusion 222 surrounding the second accommodating hole 25. The second electric connector 32 is arranged on the circuit board 60 and extends into the insulating protrusion 222. The protective shell 15 is inserted into the annular gap between the insulating protrusion 222 and the hole wall of the second accommodating hole 25. In this embodiment, the insulating protrusion 222 provides insulation protection for the second electric connector 32. After the protective shell 15 is inserted into the annular gap, the protective shell 15 and the insulating protrusion 222 jointly act on the outer periphery of the first electric connector 31 and the second electric connector 32, and surround the first electric connector 31 and the second electric connector 32 in the circumferential direction, thereby providing good insulation and protection for the first electric connector 31 and the second electric connector 32, avoiding collision between the first electric connector 31 and the second electric connector 32 and other structures, and maintaining the stability of the electrical connection of the first electric connector 31 and the second electric connector 32.

[0080] In some embodiments, the first electric connector 31 is a type-c male head 31, and the second electric connector 32 is a type-c female head 32. Therefore, when the lamp body 20 is removed alone, the lamp body 20 can be directly plugged with the type-c female head 32 with the first electric connector 31 of other power supply devices, so that the lamp body 20 can be used alone and is not dependent on the adapter 10.

[0081] In other embodiments, the first electric connector 31 and the second electric connector 32 adopt a PIN pin contact connection structure.

[0082] The application further provides a lamp, which can be a desk lamp or a floor lamp, and the like, without being specifically limited. Please refer to the above embodiments for details. Figure 1 The lamp comprises a detachable electrical connection structure, a support base 70, and a connecting rod 80.
