[0060] The technical solutions in the embodiments of the present application will be described below in conjunction with the drawings in the embodiments of the present application. In the description of the embodiments of the present application, unless otherwise specified, " / " means or, for example, A / B can mean A or B; "and / or" in this article is only a description of the association relationship of associated objects, indicating that there can be three relationships, for example, A and / or B can mean: A exists alone, A and B exist at the same time, and B exists alone. In addition, in the description of the embodiments of the present application, "multiple" means two or more than two.

[0061] In the following, the terms "first" and "second" are used for descriptive purposes only and are not to be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features.

[0062] As mentioned in the background technology section, the tree lamp in the related art includes a lamp housing at the top and a base at the bottom. The lamp housing is detachably connected to the base. When the connection between the lamp housing and the base is easily loosened, the lamp housing will rotate or shake around the axis of the base. In this way, the angle of the lamp housing changes randomly, which is not conducive to the normal use of the product and has low reliability.

[0063] Based on this, the embodiment of the present application provides a tree lamp 10 to avoid or reduce the rotation and shaking of the lamp housing 100 when it is installed on the base 200.

[0064] Combined with reference Figure 1 and Figure 2 The embodiment of the present application provides a tree lamp 10, which includes a lamp housing 100 and a base 200. The lamp housing 100 is configured to have a tree shape, and the tree shape can make the lamp housing 100 play a decorative role. The lower end of the lamp housing 100 is provided with a mounting portion 110, and the top surface of the base 200 is provided with a mounting groove 210 adapted to the mounting portion 110. The mounting portion 110 is detachably mounted in the mounting groove 210, so that the lamp housing 100 can be detachably mounted on the base 200, which is convenient for storage, carrying and separate maintenance.

[0065] Combined with reference Figure 3 , Figure 4 , Figure 5 and Figure 6 The mounting portion 110 and / or the mounting slot 210 is provided with a limiting structure 300. When the mounting portion 110 is installed in the mounting slot 210, the limiting structure 300 abuts against the mounting portion 110 or the mounting slot 210 to limit the rotation of the mounting portion 110 relative to the mounting slot 210 in at least one direction.

[0066] Specifically, the mounting portion 110 is a columnar structure, the mounting groove 210 is a circular groove, and the mounting portion 110 can be connected to the base 200 by rotating relative to the mounting groove 210. It can be understood that in other embodiments, the mounting portion 110 can be set on the base 200, and the mounting groove 210 adapted to the mounting portion 110 can be set on the lamp housing 100, that is, the mounting portion 110 and the mounting groove 210 are interchanged.

[0067] The user can install and disassemble the lamp housing 100 and the base 200 by rotating the mounting portion 110 relative to the base 200. The installation and disassembly process is easy to operate, saving time and effort. It can be understood that in other embodiments, the mounting portion 110 and the mounting groove 210 can also be set to other shapes. For example, the mounting portion 110 is set to a conical structure, and the mounting groove 210 is a corresponding conical groove.

[0068] Continue to refer Figures 3 to 6 , Figure 4 yes Figure 3 A partial enlarged view of the mounting portion 110 in area A, Figure 6 yes Figure 5 A partial enlarged view of the mounting groove 210 in area B.

[0069] In one embodiment, the limiting structure 300 includes a first protrusion 310 and a second protrusion 320. The first protrusion 310 is formed on the outer wall of the mounting portion 110 and extends along the circumference of the mounting portion 110. The second protrusion 320 is formed on the inner wall of the mounting groove 210 and extends along the axial direction of the mounting groove 210. When the mounting portion 110 is inserted into the mounting groove 210 and rotated to a preset angle, the side edge of the first protrusion 310 abuts against the side edge of the second protrusion 320, and the clockwise or counterclockwise rotation of the mounting portion 110 along its circumference is limited by the second protrusion 320, so as to avoid the mounting portion 110 from rotating too much, causing the mounting portion 110 to be stuck in the mounting groove 210, and preventing the lamp housing 100 from being detached from the base 200. In addition, the second protrusion 320 can limit the further rotation of the first protrusion 310, and can avoid or reduce the rotation or shaking of the lamp housing 100 relative to the base 200.

[0070] It should be noted that the "preset angle" in the entire application is not limited to a specific value. The "preset angle" depends on the position of the limiting structure 300 in the tree light 10. The manufacturer can freely set the position of the limiting structure 300 according to needs.

[0071] Specifically, Figure 6 It is shown that the mounting groove 210 is further provided with a third protrusion 330, which is extended along the circumference of the mounting groove 210 and is higher than the second protrusion 320. That is to say, in the height direction of the mounting groove 210, the third protrusion 330 and the second protrusion 320 are staggered, and the distance from the third protrusion 330 to the bottom of the groove is greater than the distance from the second protrusion 320 to the bottom of the groove. When the mounting portion 110 is inserted into the mounting groove 210 and rotated to a preset angle, the upper edge of the first protrusion 310 abuts against the lower edge of the third protrusion 330, and the movement of the mounting portion 110 along the axial direction is restricted, and the lamp housing 100 will not be separated from the base 200.

[0072] In this embodiment, the process of installing and removing the lamp housing 100 from the base 200 is as follows:

[0073] Insert the mounting part 110 into the mounting groove 210, and then rotate the lamp housing 100. When the lamp housing 100 drives the mounting part 110 to rotate until the upper edge of the first protrusion 310 contacts the lower edge of the third protrusion 330, the movement of the mounting part 110 along the axial direction is restricted. Continue to rotate the lamp housing 100. The lamp housing 100 drives the mounting part 110 to rotate until the side edge of the first protrusion 310 abuts against the side edge of the second protrusion 320. The second protrusion 320 restricts further rotation of the mounting part 110 along the circumferential direction. At this time, the lamp housing 100 rotates to the maximum angle, and the lamp housing 100 and the base 200 remain in a relatively fixed state. When the lamp housing 100 needs to be removed from the base 200, rotate the lamp housing 100 in the opposite direction, separate the side edge of the first protrusion 310 from the side edge of the second protrusion 320, and continue to rotate the lamp housing 100 until the upper edge of the first protrusion 310 and the lower edge of the third protrusion 330 are completely separated. At this time, the movement of the mounting part 110 along the axial direction is no longer restricted, and the lamp housing 100 can be removed from the base 200.

[0074] It can be understood that in the process of rotating the mounting portion 110 in a certain direction, when the mounting portion 110 rotates to the point where the upper edge of the first protrusion 310 contacts the lower edge of the second protrusion 320, the lamp housing 100 and the base 200 will be connected together, and the mounting portion 110 continues to be rotated. When the upper edge of the first protrusion 310 is separated from the lower edge of the third protrusion 330, the axial limit of the mounting portion 110 is cancelled, and the lamp housing 100 can be detached from the base 200, so that errors may occur during the assembly process of the lamp housing 100 and the base 200. For example, if the mounting portion 110 is rotated at an angle that is too large, the upper edge of the first protrusion 310 contacts the lower edge of the second protrusion 320 and then separates, resulting in failure to successfully connect the lamp housing 100 and the base 200; or, if the mounting portion 110 is rotated at a large angle, the contact area between the upper edge of the first protrusion 310 and the lower edge of the second protrusion 320 is small, resulting in a loose connection between the lamp housing 100 and the base 200.

[0075] In this embodiment, since the second protrusion 320 limits the maximum rotation angle of the mounting portion 110, when the lamp housing 100 is rotated until the side edge of the first protrusion 310 abuts against the side edge of the second protrusion 320, the upper edge of the first protrusion 310 abuts against the lower edge of the third protrusion 330, so as to avoid excessive rotation angle of the mounting portion 110 during the assembly of the lamp housing 100 and the base 200, thereby preventing the problem of unsuccessful connection or loose connection between the lamp housing 100 and the base 200.

[0076] Specifically, in one embodiment, the second protrusion 320 and the third protrusion 330 are an integrally formed continuous structure, which is L-shaped as a whole. When the side edge of the first protrusion 310 abuts against the side edge of the second protrusion 320, the contact area between the upper edge of the first protrusion 310 and the lower edge of the third protrusion 330 is the largest, and the connection is the strongest. In addition, the second protrusion 320 and the third protrusion 330 can also be a split structure arranged at intervals.

[0077] Furthermore, there are multiple third protrusions 330, which are arranged at intervals along the circumference of the mounting groove 210, and the number of first protrusions 310 is equal to the number of third protrusions 330 and the positions correspond to each other. When the lamp housing 100 is mounted on the base 200, the upper edge of each first protrusion 310 contacts the lower edge of a corresponding third protrusion 330. In this way, the force uniformity of the mounting portion 110 is improved, and the connection between the mounting portion 110 and the base 200 can be made more secure.

[0078] In this embodiment, the number of the second protrusion 320 is one, that is, only one second protrusion 320 can limit the first protrusion 310 from continuing to rotate, and there is no need to set up extra second protrusions 320. Of course, in other embodiments, the manufacturer can also set up multiple second protrusions 320 as needed, and this application does not limit this.

[0079] Further, the number of the third protrusions 330 may be three or four, and the plurality of third protrusions 330 may be evenly distributed along the circumference of the mounting groove 210. It is understood that the more the number of the third protrusions 330, the better the force uniformity of the mounting portion 110. However, if the number of the third protrusions 330 is too large, the size of the gap between two adjacent third protrusions 330 will be smaller, which makes it more difficult to insert the mounting portion 110 into the mounting groove 210. Therefore, the present application sets the number of the third protrusions 330 to three or four, which can not only make the mounting portion 110 have better force uniformity, but also make it easier for the mounting portion 110 to be inserted into the mounting groove 210.

[0080] In another embodiment, in conjunction with reference Figure 7 , Figure 8 , Fig. 9 and Fig.10 , Figure 8 yes Figure 7 A partial enlarged view of the mounting portion 110 in area C, Fig.10 yes Fig. 9 A partial enlarged view of the mounting groove 210 in area D.

[0081] The limiting structure 300 includes a first protrusion 310 and a limiting groove 340. The first protrusion 310 is formed on the side wall of the mounting portion 110 and extends along the axial direction of the mounting portion 110. The limiting groove 340 is an L-shaped groove and is formed on the inner wall of the mounting groove 210. The limiting groove 340 includes a first groove 341 extending along the axial direction of the mounting groove 210 and a second groove 342 extending along the circumferential direction of the mounting groove 210. During the process of installing the lamp housing 100 on the base 200, the first protrusion 310 enters the first groove 341 through the opening of the first groove 341 and then enters the second groove 342 and rotates to a preset angle along the circumferential direction. The side edge of the first protrusion 310 abuts against the side wall of the second groove 342 to limit the further rotation of the mounting portion 110. At the same time, the upper edge of the first protrusion 310 abuts against the upper edge of the second groove 342 to limit the movement of the mounting portion 110 along the axial direction.

[0082] Specifically, the number of the first protrusions 310 and the limiting grooves 340 are both two, the two limiting grooves 340 are evenly distributed along the circumference of the mounting groove 210, the two first protrusions 310 are evenly distributed along the circumference of the mounting portion 110, and the two first protrusions 310 correspond to the two limiting grooves 340 one by one. In this way, it is beneficial to improve the force uniformity of the mounting portion 110, and the connection between the mounting portion 110 and the base 200 can also be made more secure.

[0083] In this embodiment, the process of installing and removing the lamp housing 100 from the base 200 is as follows:

[0084] Insert the first protrusion 310 of the mounting part 110 into the first groove 341 of the limiting groove 340, and then rotate the lamp housing 100. When the upper edge of the first protrusion 310 contacts the upper groove wall of the second groove 342, the movement of the mounting part 110 along the axial direction is restricted. Continue to rotate the lamp housing 100. The lamp housing 100 drives the mounting part 110 to rotate until the side edge of the first protrusion 310 abuts against the side wall of the second groove 342. The side wall of the second groove 342 restricts further rotation of the mounting part 110 along the circumferential direction. At this time, the lamp housing 100 rotates to the maximum angle, and the lamp housing 100 and the base 200 maintain a relatively fixed connection state. When the lamp housing 100 needs to be removed from the base 200, rotate the lamp housing 100 in the opposite direction, separate the side edge of the first protrusion 310 from the side wall of the second groove 342, and continue to rotate the lamp housing 100 until the upper edge of the first protrusion 310 is completely separated from the upper edge of the second groove 342. At this time, the movement of the mounting part 110 along the axial direction is no longer restricted, and the lamp housing 100 can be removed from the base 200.

[0085] In summary, the tree lamp 10 in the embodiment of the present application forms a first protrusion 310 on the outer wall of the mounting portion 110, and forms a second protrusion 320 or a limiting groove 340 on the inner wall of the mounting groove 210. When the mounting portion 110 is inserted into the mounting groove 210 and rotated to a preset angle, the side edge of the first protrusion 310 abuts against the side edge of the second protrusion 320 or the side wall of the limiting groove 340 to limit the continued rotation of the first protrusion 310, thereby limiting the continued rotation of the mounting portion 110 in a certain direction relative to the base 200, so as to limit the rotation or shaking of the lamp housing 100 relative to the base 200.

[0086] It can be understood that the above embodiment is only an exemplary description of the limiting structure 300 and is not a limitation of the limiting structure 300 . The tree lamp 10 can also be provided with other forms of limiting structures 300 to limit the rotation or shaking of the lamp housing 100 relative to the base 200 .

[0087] For example, a first magnetic member is provided on the mounting portion 110, and a second magnetic member is provided at a corresponding position of the mounting groove 210. When the mounting portion 110 is rotated to a preset angle in the mounting groove 210, the first magnetic member is magnetically connected to the second magnetic member to limit further rotation of the mounting portion 110. At this time, the magnetic connection also limits the reverse rotation of the mounting portion 110. Alternatively, the first protrusion 310 and the second protrusion 320 are both composed of magnetic members. When the first protrusion 310 abuts against the second protrusion 320, the second protrusion 320 limits the continued rotation of the mounting portion 110. At the same time, the magnetic connection between the first protrusion 310 and the second protrusion 320 limits the reverse rotation of the mounting portion 110. The user needs to use a greater force to reversely rotate the mounting portion 110. That is, in some possible embodiments, the limiting structure 300 can simultaneously limit the forward and reverse rotation of the mounting portion 110.

[0088] refer to Figures 11 to 14 , in one embodiment, Fig.13 and Fig.14 The lamp housing 100 is shown as having a receiving cavity 120 disposed inside, the tree lamp 10 further comprising a light emitter 400 disposed in the receiving cavity 120, and the base 200 is provided with a power supply unit 220 for supplying power to the light emitter 400. The power supply unit 220 can be electrically connected to the light emitter 400 by connecting with a wire 600 or the like. Of course, in some possible embodiments, the light emitter 400 may not be disposed in the receiving cavity 120 inside the lamp housing 100, but may be directly fixed to the outer surface of the lamp housing 100.

[0089] Specifically, the mounting portion 110 is provided with an electrical contact 111 electrically connected to the light emitting body 400, and the mounting groove 210 is provided with a conductive structure 211 electrically connected to the power supply unit 220. When the mounting portion 110 is installed in the mounting groove 210, the electrical contact 111 contacts the conductive structure 211 to achieve electrical connection.

[0090] In the related art, the light emitting body 400 is directly connected to the power supply unit 220 through the wire 600, so that it is difficult to completely separate the upper lamp housing 100 and the bottom base 200. Even if the lamp housing 100 and the base 200 are separated, they will be constrained by the wire 600. In this way, when the base 200 needs to be repaired separately, it will be inconvenient.

[0091] In this embodiment, the mounting portion 110 is provided with an electrical contact 111, and the mounting groove 210 is provided with a conductive structure 211. When the lamp housing 100 is mounted on the base 200, the light-emitting body 400 and the power supply unit 220 are electrically connected through the electrical contact 111, the conductive structure 211, etc., and the power supply unit 220 can provide electrical energy for the light-emitting body 400. When the lamp housing 100 is separated from the base 200, the electrical contact 111 is also separated from the conductive structure 211, so that the lamp housing 100 and the base 200 can be completely separated without being constrained, which can improve the convenience of the base 200 when it is repaired separately, and it is more convenient to store and carry.

[0092] The luminous body 400 is an object that can emit light when powered on, such as an incandescent lamp, an LED lamp, etc. The luminous body 400 can be electrically connected to the electrical contact 111 through a wire 600 .

[0093] The electrical contact 111 and the conductive structure 211 are both made of conductors. For cost considerations, the conductors may be made of common metal conductors, such as copper, aluminum, nickel, etc.

[0094] In one embodiment, in conjunction with reference Figures 3 to 6 The power contact 111 is arranged inside the mounting portion 110, and a first through hole 112 is arranged at the bottom of the mounting portion 110, and the first through hole 112 is used to expose the power contact 111. There is one power contact 111 and it is located at the center of the mounting portion 110. The conductive structure 211 is a conductive column 2111 arranged at the center of the mounting groove 210, and a socket 2111a for inserting the power contact 111 is arranged at one end of the conductive column 2111 close to the power contact 111.

[0095] In this embodiment, the power contact 111 is disposed inside the mounting portion 110, that is, the power contact 111 is built into the mounting portion 110. On this basis, the number of the power contact 111 is one and is located at the center of the mounting portion 110, and the conductive structure 211 is a conductive column 2111 disposed at the center of the mounting groove 210. Since the power contact 111 and the conductive column 2111 are both located at the center position, in this way, during the rotation of the mounting portion 110 relative to the mounting groove 210, the power contact 111 and the conductive structure 211 can always remain relative to each other up and down, and the contact relationship between the power contact 111 and the conductive structure 211 will not be affected by the rotation angle of the mounting portion 110.

[0096] In another embodiment, in conjunction with reference Figures 7 to 10 The electrical contact 111 is disposed at the bottom of the mounting portion 110. There are two electrical contacts 111, and the distances between the two electrical contacts 111 and the center of the mounting portion 110 are not equal. The conductive structure 211 is located at the bottom wall of the mounting groove 210. The conductive structure 211 includes a first conductive sheet 2112 and a second conductive sheet 2113. The first conductive sheet 2112 is a circular conductive sheet, and the second conductive sheet 2113 is an annular conductive sheet and is disposed around the first conductive sheet 2112. There is a gap between the first conductive sheet 2112 and the second conductive sheet 2113.

[0097] It can be understood that the two power contacts 111 are used to contact the first conductive sheet 2112 and the second conductive sheet 2113 respectively. Compared with the method of only providing one power contact 111 , such a configuration is conducive to reducing impedance, thereby reducing the energy consumption of the tree lamp 10 .

[0098] In addition, the distances between the two power contacts 111 and the center of the mounting portion 110 are not equal, wherein the power contact 111 with a smaller distance from the center of the mounting portion 110 is configured to contact the first conductive sheet 2112, and the power contact 111 with a larger distance from the center of the mounting portion 110 is configured to contact the second conductive sheet 2113. Since the first conductive sheet 2112 and the second conductive sheet 2113 are circular conductive sheets and annular conductive sheets, respectively, during the rotation of the mounting portion 110 relative to the mounting groove 210, the power contact 111 and the corresponding conductive sheet can always be opposite to each other up and down without misalignment, so that the contact relationship between the power contact 111 and the corresponding conductive sheet will not be affected by the rotation angle of the mounting portion 110.

[0099] Further, one of the two power contacts 111 is located at the center of the mounting portion 110, and the other can be offset from the center of the mounting portion 110, or both power contacts 111 are offset from the center of the mounting portion 110. If one power contact 111 is located at the center of the mounting portion 110, the area of ​​the first conductive sheet 2112 can be set relatively small, which is more conducive to the reasonable arrangement of the conductive sheet in a limited space. If both power contacts 111 are offset from the center of the mounting portion 110, the area of ​​the first conductive sheet 2112 needs to be set relatively large, so that in the horizontal direction, the area of ​​the first conductive sheet 2112 can cover the position of one of the power contacts 111.

[0100] The lamp housing 100 may be made of a resin material, such as a thermosetting resin, so that the lamp housing 100 not only has good hardness, but also has good high temperature resistance and will not melt due to heat. Fig.11 It is shown that a plurality of simulated branches 130 may be disposed on the lamp housing 100 so as to make the lamp housing 100 resemble a tree in shape.

[0101] refer to Figure 11 to Figure 12 The lamp housing 100 includes a shell 101, a mounting portion 110 detachably connected to the lower end of the shell 101, an accommodating cavity 120 is located in the shell 101, the mounting portion 110 is a sleeve structure 113 and an electrical contact 111 is arranged on the sleeve structure 113, the lower end of the shell 101 is a hollow cylindrical structure 101c, the inner cavity of the cylindrical structure 101c is connected to the accommodating cavity 120 in the shell 101 or is regarded as a part of the accommodating cavity 120, and the sleeve structure 113 is detachably sleeved on the inner wall or outer wall of the cylindrical structure 101c.

[0102] Since the light emitting body 400 and the electrical contact 111 need to be electrically connected through the wire 600 or other conductive means, when assembling the lamp housing 100, the electrical contact 111 needs to be connected to the wire 600, etc., and the mounting portion 110 is set to be detachably connected to the housing 101, so that the wire 600 can be easily connected, which is convenient for assembly. In addition, when the electrical contact 111 or the light emitting body 400 is damaged, it is convenient to repair or replace.

[0103] Specifically, refer to Fig.11In this embodiment, the sleeve structure 113 is threadedly connected to the cylindrical structure 101c, and the sleeve structure 113 can be connected to or detached from the cylindrical structure 101c at the lower end of the shell 101 by rotating. The inner wall of the sleeve structure 113 is formed with an internal thread, and the outer wall of the cylindrical structure 101c is formed with an external thread matching the internal thread. The first protrusion 310 is located on the outer wall of the sleeve structure 113, and the sleeve structure 113 is sleeved on the outer wall of the cylindrical structure 101c.

It can be understood that in other embodiments, the block can be provided in the cylindrical structure 101c, the slot is provided in the sleeve structure 113, and the position of the first protrusion 310 is adjusted accordingly.

[0105] It should be noted that, in other embodiments, the sleeve structure 113 may also be detachably connected to the cylindrical structure 101c by other means, including but not limited to interference fit and magnetic connection.

[0106] In one embodiment, reference Fig.14 The power supply unit 220 includes a battery 221 and a circuit board 222, and the conductive structure 211 and the battery 221 are both electrically connected to the circuit board 222. A circuit is provided on the circuit board 222, and the battery 221 and the conductive structure 211 are both connected to the circuit, so that the battery 221 can power the light-emitting body 400.

[0107] In one embodiment, reference Fig.13The housing 101 includes a first housing 101a and a second housing 101b connected to each other. The first housing 101a and the second housing 101b can be manufactured and formed separately. Before connecting the first housing 101a and the second housing 101b, the light emitting body 400 can be assembled with the first housing 101a or the second housing 101b, and then the first housing 101a and the second housing 101b are connected together by screw connection, glue bonding, etc. In this way, when the light emitting body 400 in the housing 101 is damaged, the housing 101 can be disassembled to replace the light emitting body 400, which is convenient for maintenance.

[0108] Continue to refer Figure 1 The tree lamp 10 further includes a control switch 500, which is electrically connected to the circuit board 222.
