[0065] 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.

[0066] 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.

[0067] In the description of this embodiment, unless otherwise specified, "multiple" means two or more. The above content is only a specific implementation of the present application, but the protection scope of the present application is not limited thereto. Any changes or replacements within the technical scope disclosed in the present application should be included in the protection scope of the present application. Therefore, the protection scope of the present application shall be subject to the protection scope of the claims.

[0068] 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, a lamp is arranged on the lamp housing, a power supply unit is arranged in the base, and the power contact of the lamp housing contacts the conductive structure of the lamp holder so that the power supply unit supplies power to the LED lamp. When the contact between the power contact of the lamp housing and the conductive structure of the base becomes loose, the light-emitting body on the lamp housing will flicker or go out, affecting the lighting effect.

[0069] Based on this, the present application provides a tree lamp 10 to improve the stability of the electrical connection between the lamp housing 100 and the base 300 .

[0070] Combined with reference Figures 1 to 3 The embodiment of the present application provides a tree lamp 10, which includes a lamp housing 100, a light-emitting body 200 and a base 300. The lamp housing 100 is configured to have a tree shape, and the tree shape enables the lamp housing 100 to serve as a decoration. The light-emitting body 200 is arranged on the lamp housing 100. Specifically, the light-emitting body 200 can be arranged in the inner cavity of the lamp housing 100 or fixed on the outer surface of the lamp housing 100, and the lamp housing 100 is installed on the base 300.

[0071] Figure 2 and Figure 3It is shown that the lower end of the lamp housing 100 is formed with a mounting portion 110 and an electrical contact 120, the light-emitting body 200 is electrically connected to the electrical contact 120, the top surface of the base 300 is formed with a mounting groove 310, a conductive structure 313 is arranged in the mounting groove 310, a power supply unit 320 is arranged inside the base 300, and the conductive structure 313 is electrically connected to the power supply unit 320. The electrical contact 120 or the conductive structure 313 includes an elastic member 400, and when the mounting portion 110 is installed in the mounting groove 310, the electrical contact 120 contacts the conductive structure 313 and the elastic member 400 is compressed.

[0072] It can be understood that in the tree lamp 10 in the embodiment of the present application, the power contact 120 or the conductive structure 313 is provided with an elastic member 400. When the lamp housing 100 is installed on the base 300, the power contact 120 and the conductive structure 313 are in contact to realize the electrical connection between the power supply unit 320 and the light-emitting body 200, and at this time the elastic member 400 is in a compressed state. When the connection between the lamp housing 100 and the base 300 is slightly loose, that is, a gap appears between the power contact 120 and the conductive structure 313 or there is a tendency for a gap to appear, the elastic member 400 releases the elastic force to keep the power contact 120 and the conductive structure 313 in a state of abutting each other, and the electrical connection between the power supply unit 320 and the light-emitting body 200 is more stable.

[0073] The light-emitting body 200 is an object that can emit light when powered on, such as an incandescent lamp or an LED lamp. The light-emitting body 200 can be electrically connected to the power contact 120 through a wire 500 .

[0074] The electrical contact 120 and the conductive structure 313 are both made of conductors. For cost considerations, the conductors may be made of common metal conductors, such as copper, aluminum, nickel, etc.

[0075] Combined with reference Figures 4 to 9 , Figure 4 is a schematic diagram of the structure of a lamp housing in an embodiment, Figure 5 for Figure 4 Enlarged view of area A in the middle lamp housing. Figure 6 for Figure 4 The schematic diagram of the structure of the base in the embodiment shown, Figure 7 for Figure 6 A magnified view of the base B area. Figure 8 for Figure 4 A cross-sectional view of a tree light in the illustrated embodiment, Fig. 9 for Figure 8 An enlarged view of section view area C is shown.

[0076] In one embodiment, the conductive structure 313 includes an elastic member 400 . The elastic member 400 is disposed on the bottom wall of the mounting slot 310 and is electrically connected to the power supply unit 320 . Figure 7The elastic member 400 is schematically shown as the conductive structure 313. It can be understood that in other embodiments, the elastic member 400 can be used as a part of the conductive structure 313, and the manufacturer can freely set it according to needs.

[0077] There are two elastic members 400 , which are arranged at intervals, and the distances between the two elastic members 400 and the center of the mounting groove 310 are equal. There are two power contacts 120 , and the two power contacts 120 correspond to the elastic members 400 one by one.

[0078] It can be understood that since the elastic member 400 accumulates elastic force after being compressed, thereby generating abutting force on the mounting portion 110, providing two elastic members 400 can improve the force uniformity of the mounting portion 110 and also make the connection between the mounting portion 110 and the base 300 more stable. In addition, compared with only providing one elastic member 400 electrically connected to the electrical contact 120, providing two elastic members 400 and two electrical contacts 120 in one-to-one correspondence is conducive to reducing impedance, thereby reducing the energy consumption of the tree lamp 10.

[0079] Specifically, 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. Figure 1 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.

[0080] Specifically, continue to refer to Figure 2 and Figure 3 The mounting portion 110 is detachably connected to the mounting groove 310, which enables the lamp housing 100 to be separated from the base 300. When the lamp housing 100 is separated from the base 300, the electrical contact 120 is also separated from the conductive structure 313, which enables the lamp housing 100 and the base 300 to be completely separated without being constrained by the wire 500, etc., making it convenient to repair the lamp housing 100 or the base 300 separately.

[0081] Specifically, the detachable connection between the mounting portion 110 and the mounting groove 310 can be a threaded connection, a magnetic connection, an interference fit, a snap connection, etc. Of course, in some other embodiments, the connection between the lamp housing 100 and the base 300 can be set to be non-detachable, such as glue bonding or welding.

[0082] In one embodiment, in conjunction with reference Figures 4 to 9 The inner wall of the mounting groove 310 is formed with a first protrusion 311, and the outer wall of the mounting portion 110 is formed with a limiting groove 111 adapted to the first protrusion 311. Figure 8 and Fig. 9It is shown that the mounting portion 110 can be inserted into the mounting groove 310 and at least part of the first protrusion 311 is embedded in the limiting groove 111 to limit the housing from being separated from the base 300. When the lamp housing 100 needs to be detached from the base 300, the user can hold the lamp housing 100 and use a large force to pull the mounting portion 110 out of the mounting groove 310 to separate the lamp housing 100 from the base 300. It can be understood that in other embodiments, the first protrusion 311 and the limiting groove 111 can be interchanged, that is, the first protrusion 311 is set on the outer wall of the mounting portion 110, and the corresponding limiting groove 111 is set on the inner wall of the mounting groove 310.

[0083] Specifically, there are two first protrusions 311, which are respectively located on opposite sides of the mounting portion 110, and there are two limiting grooves 111, which are respectively corresponding to the two first protrusions 311. Protrusions are provided on opposite sides of the mounting portion 110, which is conducive to improving the force stability of the mounting portion 110, and can also make the connection between the mounting portion 110 and the mounting groove 310 more secure, avoiding looseness caused by one side of the mounting portion 110 being tilted.

[0084] Combined with reference Figures 10 to 15 , Fig.10 This is a schematic diagram of the structure of a lamp housing in another embodiment of the present application. Fig.11 for Fig.10 An enlarged view of the lamp housing area D is shown, Fig.12 for Fig.10 The schematic diagram of the structure of the base in the embodiment shown, Fig.13 for Fig.12 An enlarged view of the base area E is shown, Fig.14 for Fig.10 A cross-sectional view of the tree light of the illustrated embodiment, Fig.15 for Fig.14 An enlarged view of section view area F is shown.

[0085] In another embodiment, a clamping groove 112 is formed on the outer wall of the mounting portion 110 , and a clamping block 312 matched with the clamping groove 112 is formed on the inner wall of the mounting groove 310 . Fig.14 and Fig.15 It is illustrated that the mounting portion 110 can be inserted into the mounting slot 310 and at least a portion of the block 312 is embedded in the slot 112. It is understood that in other embodiments, the block 312 and the slot 112 can be interchanged, that is, the slot 112 is arranged on the inner wall of the mounting slot 310, and the corresponding block 312 is arranged on the outer wall of the mounting portion 110.

[0086] Specifically, there are two clamping blocks 312, which are respectively located at opposite sides of the mounting groove 310, and there are two clamping grooves 112, and the clamping blocks 312 correspond to the clamping grooves 112 one by one. The clamping blocks 312 are simultaneously arranged on the inner walls of the opposite sides of the mounting groove 310, which is conducive to improving the force stability of the mounting portion 110, and can also make the connection between the mounting portion 110 and the mounting groove 310 more firmly, and avoid looseness caused by one side of the mounting portion 110 being tilted.

[0087] Further, Fig.15 The block 312 is shown to include a fixed end 3121 and a rotating end 3122 opposite to each other, the fixed end 3121 is connected to the inner wall of the mounting groove 310, and the base 300 is provided with an escape space 330 for the block 312 to rotate, and the escape space 330 is located on the side of the block 312 away from the mounting groove 310. When the mounting portion 110 is mounted in the mounting groove 310, the bottom of the mounting portion 110 presses the rotating end 3122, so that the rotating end 3122 is elastically deformed and rotates in a direction away from the mounting portion 110, and the mounting portion 110 continues to be inserted into the mounting groove 310 until the rotating end 3122 is aligned with the slot 112, and at least a portion of the rotating end 3122 is embedded in the slot 112.

[0088] refer to Fig.16 The lamp housing 100 includes a housing 101, a mounting portion 110 is disposed at the lower end of the housing 101, and an electrical contact 120 is disposed in the inner cavity of the mounting portion 110. It can be understood that in some embodiments, the electrical contact 120 may not be disposed in the mounting portion 110, but may be disposed at other positions of the housing 101.

[0089] Combined with reference Figures 16 to 18 In one embodiment, the electrical contact 120 includes a contact pin 121 and an elastic member 400. One end of the contact pin 121 is exposed to the mounting portion 110, and the opposite ends of the elastic member 400 are respectively connected to the contact pin 121 and the mounting portion 110. When the mounting portion 110 is installed in the mounting groove 310, the contact pin 121 contacts the conductive structure 313, and then the mounting portion 110 is inserted into the mounting groove 310. The elastic member 400 in the electrical contact 120 is compressed and accumulates elastic force, and finally the mounting portion 110 is fixed in the mounting groove 310.

[0090] Specifically, there are two contact pins 121 , one of which is located at the center of the mounting portion 110 , and the other is offset from the center of the mounting portion 110 . Fig.18The conductive structure 313 is illustrated as including a first conductive sheet 3131 and a second conductive sheet 3132, which are used to contact different contact pins 121. The first conductive sheet 3131 is a circular conductive sheet, and the second conductive sheet 3132 is an annular conductive sheet and is arranged around the first conductive sheet 3131. There is a gap between the first conductive sheet 3131 and the second conductive sheet 3132.

[0091] It can be understood that setting two contact pins 121 to contact two conductive sheets in a one-to-one correspondence is beneficial to reducing impedance compared to setting only one contact pin 121 to contact one conductive sheet, thereby reducing the energy consumption of the tree lamp 10.

[0092] In addition, since the first conductive sheet 3131 and the second conductive sheet 3132 are respectively a circular conductive sheet and an annular conductive sheet, in this way, during the rotation of the mounting portion 110 relative to the mounting slot 310, the contact pin 121 and the corresponding conductive sheet can always be relative to each other up and down without misalignment, so that the contact relationship between the contact pin 121 and the corresponding conductive sheet will not be affected by the rotation angle of the mounting portion 110. The first conductive sheet 3131 is set to be circular so that the area of ​​the first conductive sheet 3131 can be set to be relatively small, which is more conducive to the reasonable arrangement of the conductive sheet in a limited space.

[0093] Specifically, the mounting portion 110 is a sleeve structure 113, and the sleeve structure 113 is detachably sleeved on the lower end of the housing 101. Since the light-emitting body 200 and the power contact 120 need to be electrically connected through the wire 500 or other conductive methods, when assembling the lamp housing 100, the power contact 120 needs to be connected to the wire 500, etc., and the mounting portion 110 is set to be detachably connected to the housing 101, which can easily connect the wire 500 and facilitate assembly. In addition, it is convenient to repair or replace when the power contact 120 or the light-emitting body 200 is damaged. The detachable connection method between the sleeve structure 113 and the lower end of the housing 101 can be a snap connection, a threaded connection, etc.

[0094] Further, the sleeve structure 113 includes a barrel 1131 and a barrel cover 1132, the barrel cover 1132 is detachably connected to the barrel 1131, the barrel cover 1132 and the barrel 1131 enclose an inner cavity of the mounting portion 110, and the contact pin 121 and the elastic member 400 are arranged in the inner cavity of the mounting portion 110. The barrel cover 1132 and the barrel 1131 are detachable, which makes it more convenient to assemble and repair the electrical contact 120. The barrel 1131 and the barrel cover 1132 can be detachably connected in a snap-fit ​​connection, a threaded connection, etc.

[0095] In one embodiment, in conjunction with reference Fig.11 and Fig.13The outer wall of the mounting portion 110 is provided with a second protrusion 114, and the inner wall of the mounting groove 310 is formed with a guide groove 314 adapted to the second protrusion 114, and the opening of the guide groove 314 is connected to the top surface of the base 300. When the mounting portion 110 is mounted in the mounting groove 310, the second protrusion 114 is first aligned with the guide groove 314, and then the second protrusion 114 is inserted into the guide groove 314 along the opening of the guide groove 314, thereby driving the mounting portion 110 to enter the mounting groove 310.

[0096] Specifically, the number of the second protrusion 114 and the number of the guide groove 314 are both one. That is to say, only when the second protrusion 114 and the guide groove 314 are aligned, the mounting portion 110 can be inserted into the mounting groove 310. When the mounting portion 110 is reversed, the second protrusion 114 and the guide groove 314 are respectively located on opposite sides of the mounting portion 110, and the second protrusion 114 cannot be aligned with the guide groove 314. At this time, the mounting portion 110 cannot be inserted into the mounting groove 310. Therefore, the mounting portion 110 can only be installed in the mounting groove 310 along a specific direction (i.e., the extending direction of the guide groove 314), so as to avoid the lamp housing 100 being installed in the wrong direction when being installed on the base 300.

[0097] In one embodiment, in conjunction with reference Figure 5 and Fig. 9 The bottom of the mounting portion 110 is formed with an arc surface 115, the tangent of the arc surface 115 is arranged at an acute angle with the axis of the mounting portion 110, and the distance from the arc surface 115 to the axis of the mounting portion 110 decreases along the mounting direction of the mounting portion 110. When the mounting portion 110 is mounted in the mounting groove 310, the arc surface 115 plays a role in guiding the bottom of the mounting portion 110 to enter the mounting groove 310. It can be understood that the mounting direction of the mounting portion 110 refers to the direction in which the mounting portion 110 enters the mounting groove 310 from the opening of the mounting groove 310.

[0098] Specifically, there are two arc surfaces 115, which are respectively located on opposite sides of the mounting portion 110. Arranging arc surfaces 115 on both sides is more conducive to the installation of the mounting portion 110. It is understood that in other embodiments, the manufacturer can set other numbers of arc surfaces 115 or no arc surface 115 as needed.

[0099] In some embodiments, reference Fig.19 The base 300 includes an upper shell 340 and a lower cover plate 350. The lower cover plate 350 is detachably connected to the upper shell 340. The upper shell 340 and the lower cover plate 350 enclose an installation cavity, and the power supply unit 320 is located in the installation cavity. Specifically, the lower cover plate 350 can be connected to the upper shell 340 by screw connection, snap connection, etc. In this way, the lower cover plate 350 can be detached from the upper shell 340, which is convenient for repairing or replacing the power supply unit 320.

[0100] Specifically, in conjunction with reference Figure 1 and Figure 2 The power supply unit 320 includes a battery 321 and a circuit board 322, and the conductive structure 313 and the battery 321 are both electrically connected to the circuit board 322. A circuit is provided on the circuit board 322, and the battery 321 and the conductive structure 313 are both connected to the circuit, so that the battery 321 can supply power to the light-emitting body 200. Of course, in other embodiments, the circuit board 322 and the light-emitting body 200 can also be powered by an external power supply.

[0101] In one embodiment, the tree lamp 10 further includes a control switch 600, which is electrically connected to the circuit board 322, and is connected to the circuit where the conductive structure 313 and the battery 321 are located to control the conduction or disconnection of the circuit. Therefore, the control switch 600 can also be used to control the lighting and extinguishing of the light emitting body 200, the brightness of the light emitting body 200, etc.

[0102] In the description of this embodiment, unless otherwise specified, "multiple" means two or more. The above content is only a specific implementation of the present application, but the protection scope of the present application is not limited thereto. Any changes or replacements within the technical scope disclosed in the present application should be included in the protection scope of the present application. Therefore, the protection scope of the present application shall be subject to the protection scope of the claims.
