Among them, the lighting assembly 100 includes an energy storage device and a first lighting lamp 110, and the energy storage device can power the first lighting lamp 110; the power box includes a box body 200 and a battery, the battery is installed in the box body 200, and a mounting cavity is opened on one side wall of the box body 200, the opening of the mounting cavity faces the outside of the box body 200, the lighting assembly 100 can be placed in the mounting cavity and electrically connected to the battery, and the first lighting lamp 110 faces the opening side of the mounting cavity; the locking assembly 300 includes a button 310, a first locking member 320 and a second locking member 330, the first locking member 320 and the second locking member 330 are respectively movably arranged on the opposite side walls of the mounting cavity, the button 310 is movably arranged on the box body 200, and the button 310 includes an unlocked position and a locked position. When the button 310 is in the locked position, the first locking member 320 and the second locking member 330 are both inserted into the lighting assembly 100, and when the button 310 is in the unlocked position, the first locking member 320 and the second locking member 330 are both detached from the lighting assembly 100.

[0043] Specifically, the lighting assembly 100 includes an energy storage device and a first lighting lamp 110. The first lighting lamp 110 can be lit by powering the energy storage device. A battery for powering the lighting assembly 100 is installed in the power supply box. The lighting assembly 100 is placed in the installation cavity. The battery can provide electrical energy to the energy storage device and / or the first lighting lamp 110. The locking assembly 300 is installed in the power supply box and is used to lock the lighting assembly 100. By switching the locking position and unlocking position of the button 310, the plug-in relationship between the first locking member 320 and the second locking member 330 and the lighting assembly 100 is changed. The first locking member 320 and the second locking member 330 are located on opposite sides of the lighting assembly 100, and the movement directions are always opposite. In this way, it is used to fix the lighting assembly 100 in the installation cavity.

[0044] The power pack can be considered a relatively heavy portable power source. Once assembled with the power pack, the lighting assembly 100, powered by a battery, can illuminate a specific area with a long battery life. The lighting assembly 100 can also be used independently for portable lighting, making it suitable for a wide range of scenarios.

[0045] Optionally, the lighting device further includes a lifting member 400 , which is installed on the bottom wall of the installation cavity. The lifting member 400 enables the lighting assembly 100 to always have a tendency to move toward the opening of the installation cavity.

[0046] Specifically, a mounting hole is provided in the bottom wall of the mounting cavity. The mounting hole is a blind hole, forming an opening in the bottom wall of the mounting cavity, and the axis of the mounting hole is consistent with the opening direction of the mounting cavity. The lifting member 400 is installed in the mounting hole, and the end of the lifting member 400 can extend out of the mounting hole and into the mounting cavity, exerting a force on the lighting assembly 100 toward the opening side of the mounting cavity. When the lighting assembly 100 switches from a locked state to an unlocked state in the mounting cavity, the lighting assembly 100 can be at least partially ejected from the mounting cavity under the action of the lifting member 400. In this way, the mounting cavity can be opened relatively deep, so that as much area of ​​the lighting assembly 100 as possible can be located in the mounting cavity. The mounting cavity not only provides protection for the lighting assembly 100, but also allows the lighting assembly 100 to be placed relatively stably in the mounting cavity.

[0047] Preferably, a plurality of lifting members 400 are provided, and at least two lifting members 400 can act on opposite ends of the lighting assembly 100 .

[0048] Optionally, the button 310 includes a first inclined surface 311 , and the first locking member 320 includes a second inclined surface 321 . The first inclined surface 311 and the second inclined surface 321 can slide relative to each other.

[0049] In this embodiment, the button 310 can move in a first direction relative to the housing 200 to switch between an unlocked position and a locked position, and the first locking member 320 can move in a second direction relative to the housing 200 to connect or disconnect with the lighting assembly 100. When the first inclined surface 311 abuts the second inclined surface 321 in the first direction, the force applied in the first direction can be redirected to the second direction, causing the first locking member 320 to move relative to the button 310 and the housing 200.

[0050] Optionally, the button 310 includes a third inclined surface 312 , and the second locking member 330 includes a fourth inclined surface 331 , and the third inclined surface 312 and the fourth inclined surface 331 are capable of sliding relative to each other.

[0051] In this embodiment, the second locking member 330 can move relative to the housing 200 in the second direction to connect or disconnect with the lighting assembly 100. When the third inclined surface 312 abuts against the fourth inclined surface 331 in the first direction, the force acting in the first direction can be redirected to the second direction, causing the second locking member 330 to move relative to the button 310 and the housing 200.

[0052] Optionally, the second locking member 330 includes a second plug-in portion 332, a connecting portion 333 and a sliding portion 334, the button 310 and the second plug-in portion 332 are located on opposite sides of the lighting assembly 100, the fourth inclined surface 331 is formed on the sliding portion 334, the second plug-in portion 332 is used to plug with the lighting assembly 100, and the connecting portion 333 connects the sliding portion 334 and the second plug-in portion 332.

[0053] Exemplarily, the button 310 and the first locking member 320 are located on the same side of the mounting cavity in the second direction, and the second plug-in portion 332 of the second locking member 330 is located on the side of the mounting cavity opposite to the first locking member 320. The moving directions of the first locking member 320 and the second locking member 330 are always opposite, that is, the inclination directions of the first inclined surface 311 and the third inclined surface 312 are opposite, and the inclination directions of the second inclined surface 321 and the fourth inclined surface 331 are opposite, so as to complete the fixed grasping of the lighting assembly 100 in the second direction. The sliding portion 334 of the second locking member 330 is located on the same side of the mounting cavity as the button 310. When the button 310 moves along the first direction, the sliding portion 334 moves along the second direction, and the sliding portion 334 drives the second plug-in portion 332 to move together through the connecting portion 333.

[0054] Optionally, the locking assembly 300 also includes a third elastic member 360, the box body 200 is provided with a first abutment block 210, the connecting portion 333 is provided with a first waist-shaped avoidance hole and is provided with a second abutment block 3331, the first abutment block 210 is inserted into the first waist-shaped avoidance hole, the third elastic member 360 is clamped between the first abutment block 210 and the second abutment block 3331, and the third elastic member 360 makes the second plug-in portion 332 have a tendency to move toward one side of the installation cavity.

[0055] In this manner, the button 310 moves in the first direction from the locked position to the unlocked position. The third inclined surface 312 and the fourth inclined surface 331 cause the second locking member 330 to move relative to the housing 200 in the second direction. The first abutting block 210 and the second abutting block 3331 move closer to each other, squeezing the third elastic member 360. The third elastic member 360 accumulates energy, causing the second plug portion 332 to move away from the mounting cavity in the second direction, allowing the lighting assembly 100 to enter and exit the mounting cavity. When the button 310 loses the external force applied to it, the third elastic member 360 recovers its deformation, causing the first abutting block 210 and the second abutting block 3331 to move away from each other, allowing the second locking member 330 to re-enter the mounting cavity or be inserted into the lighting assembly 100.

[0056] It should be noted that, in the second direction, the first abutting block 210 is adjacent to the second plug portion 332 , and the second abutting block 3331 is adjacent to the button 310 .

[0057] Preferably, the box body 200 is further provided with a guide block 220, and the connecting portion 333 is further provided with a second waist-shaped avoidance hole. The guide block 220 is inserted into the second waist-shaped avoidance hole and can slide relative to the connecting portion 333 along the second direction.

[0058] Optionally, the locking assembly 300 includes a first elastic member 340 , and the first elastic member 340 enables the button 310 to always have a tendency to move from the unlocked position to the locked position.

[0059] Optionally, the locking assembly 300 further includes a second elastic member 350 , and the second elastic member 350 allows the first locking member 320 to always have a tendency to move toward one side of the installation cavity.

[0060] In this way, the energy storage state and the relaxed state of the first elastic member 340 , the second elastic member 350 and the third elastic member 360 are kept synchronous.

[0061] Optionally, the lighting assembly 100 includes a mounting frame 120, a swing arm 130 and a second lighting lamp 140. The swing arm 130 is hinged to the mounting frame 120, the second lighting lamp 140 is arranged on the mounting frame 120, and the first lighting lamp 110 is arranged on the swing arm 130. The swing arm 130 includes a storage state and an expansion state relative to the mounting frame 120. In the storage state, the swing arm 130 is close to the mounting frame 120 and the two are arranged in a straight line. In the expansion state, the swing arm 130 and the mounting frame 120 are cross-shaped and the first lighting lamp 110 and the second lighting lamp 140 can form an illumination area in the same direction, and the illumination areas do not overlap.

[0062] Specifically, when the lighting device needs to be placed in the installation cavity, the swing arm 130 is first stored in a side wall of the mounting frame 120 to reduce the space it occupies. When needed, the first lighting lamp 110 and / or the second lighting lamp 140 are selectively used for lighting according to the usage scenario. Generally, the second lighting lamp 140 has a relatively concentrated lighting area, while the first lighting lamp 110 has a relatively large lighting area.

[0063] For example, the second lighting lamp 140 is mounted on the top of the mounting frame 120, forming a flashlight, so that the mounting frame 120 can be held for illumination. In this case, the swing arm 130 is stored in the side wall of the mounting frame 120. When the lighting assembly 100 is needed for its warning function, the swing arm 130 is flipped to the extended state, and the first lighting lamp 110 flashes or uses other warning lights to alert pedestrians.

[0064] Optionally, a magnet is provided on the side of the mounting frame 120 facing away from the second lighting lamp 140. The magnet is used to adsorb the mounting frame 120 onto other metal bases to fix the lighting assembly 100.

[0065] Optionally, the mounting bracket 120 is provided with a hook on a side facing away from the second lighting lamp 140 .
