[0036] In order to more clearly understand the above-mentioned objectives, features and advantages of the present disclosure, the scheme of the present disclosure will be further described below. It should be noted that the embodiments of the present disclosure and the features in the embodiments can be combined with each other without conflict.

[0037] In the following description, many specific details are set forth to facilitate a full understanding of the present disclosure, but the present disclosure may also be implemented in other ways different from those described herein; it is obvious that the embodiments in the specification are only part of the embodiments of the present disclosure, rather than all of the embodiments.

[0038] In the related art, a foldable lighting device may generally include a lamp holder and a lamp arm. The lamp holder and the lamp arm are rotationally connected via a rotating shaft. The battery is disposed on the lamp holder, and the lamp board is disposed on the lamp arm. Therefore, the wire needs to pass through the rotating shaft to realize electrical connection between the battery and the lamp board.

[0039] However, when the lamp arm rotates relative to the lamp holder, the rotating shaft rubs against the wire, causing the wire to be scratched.

[0040] To solve the above technical problems, please refer to Figure 1 The present application provides a foldable lighting device 100, which can be a foldable desk lamp, a foldable headlamp, a foldable flashlight, etc. For the convenience of description, the following embodiments are described by taking the foldable desk lamp as an example.

[0041] See also Figures 2 to 5 The foldable lighting device 100 may include a lamp holder 110, a lamp arm 120 and a rotating shaft 130. The lamp holder 110 may include a lamp holder shell 111 and a battery 119. The lamp holder shell 111 may include a lamp holder upper shell 1111 and a lamp holder lower shell 1112. The lamp holder upper shell 1111 is snap-connected with the lamp holder lower shell 1112. Specifically, the lamp holder upper shell 1111 and the lamp holder lower shell 1112 are snap-connected by a buckle 1113 and a slot. A first accommodating cavity 1101 is defined between the lamp holder upper shell 1111 and the lamp holder lower shell 1112. The battery 119 is located in the first accommodating cavity 1101.

[0042] Please continue reading Figures 2 to 5The lamp arm 120 may include a lamp arm housing 121 and a lamp board 126. The lamp arm housing 121 may include a lamp arm upper shell 1211 and a lamp arm lower shell 1212. The lamp arm upper shell 1211 and the lamp arm lower shell 1212 are snap-connected. Specifically, the lamp arm upper shell 1211 and the lamp arm lower shell 1212 can be snap-connected by a buckle 1113 and a slot. A second accommodating cavity 1201 is defined between the lamp arm upper shell 1211 and the lamp arm lower shell 1212. The lamp board 126 is located in the second accommodating cavity 1201. A light emitting opening 1213 is provided on the lamp arm upper shell 1211. Specifically, the lamp board 126 is snap-connected at the light emitting opening 1213, or the lamp board 126 is fixed by screw connection. The light emitting side of the lamp board 126 faces the light emitting opening 1213. A positioning rib 127 may also be provided on the circumferential outer side of the light emitting opening 1213. The positioning rib 127 is used to pre-position and prevent the lamp board 126 from loosening.

[0043] Among them, see Figures 3 to 6 The lower shell 1112 of the lamp holder may include a first connecting portion 140, the first connecting portion 140 is provided with a first opening 141 and a first through hole 142, the first opening 141 is communicated with the first accommodating cavity 1101; the lower shell 1212 of the lamp arm includes a second connecting portion 150, the second connecting portion 150 is provided with a second opening 151, a second through hole 152 and a wiring groove 153, the second opening 151 is communicated with the second accommodating cavity 1201, and the second through hole 152 is arranged opposite to the first through hole 142; the wiring groove 153 is arranged around the circumferential outer side of the second through hole 152, and is spaced apart from the second through hole 152, and the wiring groove 153 is communicated with the first opening 141 and the second opening 151 respectively; the rotating shaft 130 is passed through the first through hole 142 and the second through hole 152.

[0044] In this way, by setting the wiring groove 153 and the second through hole 152 apart, the rotating shaft 130 and the wire 180 are not in contact, so that the collision between the rotating shaft 130 and the wire 180 can be avoided, and the wire 180 can be prevented from being scratched by the rotating shaft 130, thereby extending the service life of the wire 180 and further extending the service life of the foldable lighting device 100.

[0045] The rotating shaft 130 is passed through the first through hole 142 and the second through hole 152, so that the first connecting portion 140 can be rotatably connected relative to the second connecting portion 150, thereby allowing the lamp arm 120 to rotate relative to the lamp holder 110. Specifically, the first connecting portion 140 is located at one end of the lower shell 1112 of the lamp holder, and the second connecting portion 150 is located at one end of the lower shell 1212 of the lamp arm. The foldable lighting device 100 includes a buckled state (for example Figure 1 ) and the unfolded state (e.g. Figure 7), when the foldable lighting device 100 is in a buckled state, the lamp arm 120 and the lamp holder 110 are stacked, and the light-emitting side of the lamp panel 126 faces the lamp holder 110; when the foldable device is in an unfolded state, there is an unfolding angle between the lamp arm 120 and the lamp holder 110. Specifically, the maximum unfolding angle between the lamp arm 120 and the lamp holder 110 can be 90 degrees, 120 degrees, 150 degrees, 180 degrees, 360 degrees, etc.

[0046] In the specific implementation process, please refer to Figure 7 , and refer to Figure 2 The maximum expansion angle between the lamp arm 120 and the lamp holder 110 is 180 degrees, and the lamp arm 120 can rotate from 0 to 180 degrees relative to the lamp holder 110. A limiting protrusion 112 is provided on the lower shell 1112 of the lamp holder. When the lamp arm 120 and the lamp holder 110 are expanded to 180 degrees, the limiting protrusion 112 abuts against the second connecting portion 150, so that the expansion angle between the lamp arm 120 and the lamp holder 110 stops at 180 degrees.

[0047] In some embodiments of this application, please refer to Figure 6 The lower shell 1112 of the lamp holder may further include a third connecting portion 160, which is arranged opposite to the first connecting portion 140, and the second connecting portion 150 is located between the first connecting portion 140 and the third connecting portion 160. The third connecting portion 160 is provided with a third through hole 161, and the third through hole 161 is arranged opposite to the second through hole 152, and the rotating shaft 130 is passed through the first through hole 142, the second through hole 152 and the third through hole 161.

[0048] It is understandable that the first connection part 140 and the third connection part 160 are respectively arranged on both sides of the second connection part 150, which can ensure the stability of the second connection part 150 rotating relative to the first connection part 140 and the third connection part 160, and further ensure the stability of the lamp arm 120 rotating relative to the lamp holder 110.

[0049] In some embodiments of this application, please continue to refer to Figure 6 The lamp holder lower shell 1112 may further include a support plate 170, the support plate 170 is located between the first connection part 140 and the third connection part 160, one end of the support plate 170 is connected to the first connection part 140, and the other end of the support plate 170 is connected to the third connection part 160. Therefore, by arranging the support plate 170 between the first connection part 140 and the third connection part 160, the strength of the first connection part 140 and the second connection part 150 in the direction from the first connection part 140 to the second connection part 150 can be improved, and the stability of the rotation between the lamp arm 120 and the lamp holder 110 can be further ensured.

[0050] In this way, the first connection part 140, the third connection part 160 and the support plate 170 jointly define a U-shaped accommodating space for accommodating the second connection part 150, which is beneficial for the pre-positioning of the second connection part 150 when the lamp arm 120 and the lamp holder 110 are assembled, thereby reducing the assembly difficulty of the transfer personnel.

[0051] In some embodiments of this application, please refer to Figure 6 , and refer to Figure 3 The second connection portion 150 includes a first surface facing the first connection portion 140 , and the wiring groove 153 is formed by a portion of the first surface being recessed in a direction away from the first connection portion 140 . The open mouth 1531 of the wiring groove 153 is arranged opposite to the first opening 141 .

[0052] It can be understood that when the lamp arm 120 rotates relative to the lamp holder 110, with the lamp holder 110 as a stationary reference, the second connection part 150 rotates relative to the first connection part 140, and the wire 180 passes through the first opening 141 and the open mouth 1531 of the wiring groove 153 in sequence to pass through the wiring groove 153. Since the wiring groove 153 is formed by a partial depression of the first surface, the open mouth 1531 is surrounded by the second through hole 152. When the second connection part 150 rotates, the second connection part 150 rotates relative to the wire 180 inside the wiring groove 153, and the wire 180 inside the wiring groove 153 is stationary relative to the lamp holder 110, thereby avoiding friction between the wire 180 and the first opening 141 during the rotation of the second connection part 150, further extending the service life of the wire 180 and the service life of the foldable lighting device 100.

[0053] In some embodiments of this application, please continue to refer to Figure 6 The outer wall of the wiring groove 153 is provided with a connection port 1532, which is arranged opposite to the second opening 151, that is, the wire 180 enters the wiring groove from the first opening 141 through the open opening 1531 of the wiring groove, and enters the second accommodation cavity 1201 through the connection port 1532 and the second opening 151. Thus, the wiring groove 153 is connected to the first accommodation cavity 1101 and the second accommodation cavity 1201.

[0054] Please continue to read Figure 6 The second opening 151 is formed on a side surface of the second connecting portion 150 facing the second accommodating cavity 1201, and the orthographic projection of the connecting port 1532 on the plane where the second opening 151 is located is located inside the second opening 151, that is, when the wire 180 enters the second opening 151 from the connecting port 1532, the wire 180 will not contact the side wall of the second opening 151, which can avoid friction between the wire 180 and the side wall of the second opening 151, further extending the service life of the wire 180 and the service life of the foldable lighting device 100.

[0055] In some embodiments of the present application, the second connection portion 150 includes a first side wall 155 and a second side wall 156, the first side wall 155 and the second side wall 156 are arranged opposite to each other in the extension direction of the second through hole 152, and the second through hole 152 is penetrated through the first side wall 155 and the second side wall 156. In this way, by arranging the first side wall 155 and the second side wall 156 at intervals, the material and weight of the second connection portion 150 can be reduced while ensuring that the shaft 130 penetrates the second connection portion 150, thereby saving raw materials and reducing the weight of the foldable lighting device 100.

[0056] The first surface is located on the first side wall 155 , and the wiring groove 153 is located on the first side wall 155 .

[0057] In some examples of this application, please continue to participate Figure 6 The second connection part 150 may further include a reinforcing rib 157, one end of which is connected to the first side wall 155, and the other end of which is connected to the second side wall 156. It can be understood that the reinforcing rib 157 is arranged at intervals from the second communicating hole, and thus, by providing the reinforcing rib 157, the strength of the second connection part 150 in the axial direction of the second communicating hole can be increased.

[0058] In some embodiments of the present application, a wire buckle 1114 is provided on a side surface of the lamp holder lower shell 1112 facing the first accommodating cavity 1101, and the wire 180 is adapted to be engaged with the wire buckle 1114. Thus, by providing the wire buckle 1114, the wire 180 can be prevented from moving in the first accommodating cavity 1101.

[0059] There may be multiple wire clips 1114 , and the multiple wire clips 1114 are spaced apart along the extension direction of the wire 180 , so as to further prevent the wire 180 from moving in the first accommodating cavity 1101 .

[0060] In some other embodiments of the present application, a wire buckle 1114 may also be provided in the second accommodating cavity 1201 to fix the wire 180 in the second accommodating cavity 1201 .

[0061] Among them, the space reserved for the battery 119 in the first accommodating cavity 1101 is relatively large, and the wire 180 needs to pass from under or over the battery 119. When the wire 180 passes from under the battery 119, the wire buckle 1114 is set on the lower shell 1112 of the lamp holder; when the wire 180 passes from over the battery 119, the wire buckle 1114 is set on the upper shell 1111 of the lamp holder.

[0062] In some embodiments of the present application, the rotating shaft 130 may include a bolt 131 and a nut 132, and the bolt 131 is inserted into the first through hole 142 and the second through hole 152. By providing the bolt 131 and the nut 132, the bolt 131 can be prevented from being separated from the first through hole 142 and the second through hole 152.

[0063] In some embodiments of this application, please refer to Figure 8 , and refer to Figure 2 The first accommodating cavity 1101 is also provided with a counterweight 1102, which is located on a side of the first accommodating cavity 1101 away from the first connecting portion 140. The lamp holder 110 includes a fixed end 113 and a first connecting end relative to each other. The first connecting portion 140 is located at the first connecting end, and the counterweight 1102 is located at the fixed end 113. When the foldable lighting device 100 is placed in the working position, the fixed end 113 is in contact with the workbench. The specific counterweight can be a metal block. The counterweight 1102 is used to lower the center of gravity of the lamp holder 110 and increase the stability of the foldable lighting device 100 when it is placed on the workbench.

[0064] Among them, see Figure 2 If the space in the first accommodating cavity 1101 allows, multiple batteries 119 can be placed, and the batteries 119 can be arranged close to the fixed end 113 to further lower the center of gravity of the lamp holder 110.

[0065] In some embodiments of this application, please refer to Figure 2 The side surface of the lamp holder upper shell 1111 facing away from the first accommodating cavity 1101 includes a first table top 115 and a second table top 116. The first table top 115 protrudes from the second table top 116. When the foldable lighting device 100 is in a buckled state, the lamp arm 120 is arranged opposite to the second table top 116. The first table top 115 is provided with an indicator 117, wherein the indicator 117 can be used to display whether the lamp board 126 is conductive. Specifically, the indicator 117 can be an indicator light. When the lamp board 126 is in a lighting state, the indicator light is on, and when the lamp board 126 is in an off state, the indicator light is off.

[0066] In some embodiments of this application, please refer to Figure 2 The first accommodating cavity 1101 may also include a circuit board 118, the circuit board 118 is opposite to the indicator 117, the indicator 117 is electrically connected to the circuit board 118, the battery 119 is electrically connected to the circuit board 118 through a wire 180, and the light board 126 is electrically connected to the circuit board 118 through a wire 180.

[0067] In some examples of this application, please continue to participate Figure 2The upper shell 1211 of the lamp arm can also include a transparent mask 122, which covers the light outlet opening 1213. The light emitted by the lamp board 126 can pass through the mask 122, and the mask 122 can be clamped at the light outlet opening 1213. In this way, by setting the mask 122, it can achieve dustproof and waterproof effects and protect the lamp board 126.

[0068] In some embodiments of this application, please continue to refer to Figure 2 A first magnetic member 123 is provided on the lamp arm 120, and a second magnetic member 114 is provided on the lamp holder 110. When the foldable lighting device 100 is in a buckled state, the first magnetic member 123 and the second magnetic member 114 are arranged relative to each other. It can be understood that the first magnetic member 123 and the second magnetic member 114 have the characteristic of magnetic attraction. When the unfolding angle between the lamp arm 120 and the lamp holder 110 is small, the lamp arm 120 can be driven to rotate toward the lamp holder 110 by arranging the first magnetic member 123 and the second magnetic member 114, so that the lamp arm 120 returns to the buckled position, that is, the unfolding angle between the lamp arm 120 and the lamp holder 110 is 0 degrees.

[0069] In this way, when the user does not return the lamp arm 120 to its original position, the lamp arm 120 can be driven to rotate to the locking position by providing the first magnetic member 123 and the second magnetic member 114 .

[0070] Among them, the lamp arm 120 may include a second connecting end 124 and a free end 125, the second connecting part 150 is located at the second connecting end 124, the first magnetic part 123 is located at the free end 125 of the lamp arm 120, and the second magnetic part 114 is located on the inner side of the second table top 116, so that when the unfolding angle between the lamp arm 120 and the lamp holder 110 is small, the first magnetic part 123 and the second magnetic part 114 can drive the lamp arm 120 to rotate to the snap-fit ​​position.
