[0055] As described in the background, in the related art wall-mounted floodlight, the elastic rubber plug at the mounting hole of the bottom cover of the power cabin for mounting the bolt is prone to fall off, thereby easily causing the bolt to fail to prevent water. The inventor has found that the specific reason is that the inner wall of the cabin body of the power cabin is provided with a mounting column, and one end of the screw rod of the bolt is threadedly connected with the mounting column after penetrating through the hole bottom of the mounting hole. In order to ensure the connection reliability, the end face of the mounting column is sealingly fitted with the bottom wall of the mounting hole, and the head of the bolt is fitted on and abuts against the bottom wall of the mounting hole, so that the gas in the mounting hole cannot be discharged through the hole bottom of the mounting hole. When the elastic rubber plug is inserted into the mounting hole, the gas in the mounting hole is compressed, resulting in a relatively large gas pressure in the mounting hole, and thus the elastic rubber plug is prone to fall off.

[0056] Please refer to Figure 1 and Figure 2 , an embodiment of the present application provides a power cabin assembly 100, which is applied to a wall-mounted floodlight 10.

[0057] Please refer to the combination Figures 3-4 The power cabin assembly 100 comprises a power cabin 110 and a power board 120. The power cabin 110 comprises a cabin body 111, a bottom cover 112, a first bolt 113 and an elastic plug 114.

[0058] Please refer to Figure 9 One end of the cabin body 111 has an opening 111a for the power board 120 to enter the cabin body 111. The bottom cover 112 is connected with the cabin body 111 and covers the opening 111a.

[0059] Please refer to the combination Figures 5-7 The bottom cover 112 is provided with a mounting hole 101, and the bottom wall 101a of the mounting hole 101 is provided with a connecting hole 102.

[0060] The shank of the first bolt 113 is threaded through the connecting hole 102 and is threadedly connected with the cabin body 111, and the head of the first bolt 113 is attached to and abuts against the bottom wall 101a of the mounting hole 101.

[0061] The bottom wall 101a of the mounting hole 101 is provided with a ventilation groove 103, and the ventilation groove 103 penetrates the bottom wall 101a of the mounting hole 101 to communicate the mounting hole 101 with the cabin body 111, wherein the ventilation groove 103 is at least partially located outside the contour range of the head of the first bolt 113.

[0062] The elastic plug 114 is interference-fitted with the mounting hole 101 to seal the mounting hole 101.

[0063] The power cabin assembly 100 described above, one end of the shank of the first bolt 113 penetrates the connecting hole 102 on the bottom wall 101a of the mounting hole 101 and enters the inside of the cabin body 111 to be threadedly connected with the cabin body 111. The head of the first bolt 113 is attached to and abuts against the bottom wall 101a of the mounting hole 101 to achieve the fixed connection of the bottom cover 112 with the cabin body 111. The elastic plug 114 is interference-fitted with the mounting hole 101 to seal the mounting hole, and the elastic plug 114 is located at the end of the head of the first bolt 113 away from the shank, so that the elastic plug 114 can seal the mounting hole 101 to achieve waterproofing of the mounting hole 101. The bottom wall 101a of the mounting hole 101 is provided with a ventilation groove 103. Since the ventilation groove 103 penetrates the bottom wall 101a of the mounting hole 101, and the ventilation groove 103 is at least partially located outside the contour range of the head of the first bolt 113, the ventilation groove 103 can communicate the mounting hole 101 with the cabin body 111. In this way, when the elastic plug 114 is inserted into the mounting hole 101 and squeezes the gas in the mounting hole 101, the gas in the mounting hole 101 can enter the cabin body 111 through the ventilation groove 103, so as to reduce the air pressure in the mounting hole 101, and thus avoid the elastic plug 114 from falling off due to excessive air pressure in the mounting hole 101.

[0064] Please refer to Figures 5-7 In an embodiment, the extending direction of the vent groove 103 is along the radial direction of the connecting hole 102, and one end of the vent groove 103 communicates with the connecting hole 102. That is, the direction from one end of the vent groove 103 to the other end is along the radial direction of the connecting hole 102 outward.

[0065] In the embodiment, the outer diameter of the head of the first bolt 113 is smaller than the outer diameter of the bottom wall 101a of the mounting hole 101. When the head of the first bolt 113 abuts against the bottom wall 101a of the mounting hole 101, the end of the vent groove 103 communicating with the connecting hole 102 is covered, and the end of the vent groove 103 away from the connecting hole 102 is not covered. In this way, when the elastic rubber plug 114 is inserted into the mounting hole 101 and the gas in the mounting hole 101 is squeezed, the gas in the mounting hole 101 can enter the cabin 111 through the end of the vent groove 103 away from the connecting hole 102.

[0066] Please refer to Figure 9 In combination Figure 4 In an embodiment, the inner wall of the cabin 111 is provided with a mounting column 1111, and the end surface of the mounting column 1111 abuts against the bottom wall 101a of the mounting hole 101. The end of the screw rod of the first bolt 113 away from the head is threadedly connected with the mounting column 1111.

[0067] Specifically, the mounting column 1111 is integrally formed with the inner wall of the cabin 111 and is part of the cabin 111.

[0068] Please refer to Figure 2 and Figure 5 In an embodiment, the power supply cabin assembly 100 further comprises a breathing membrane (not shown). The bottom cover 112 is provided with a breathable hole 104, and the breathing membrane is connected with the side of the bottom cover 112 facing the inside of the cabin 111 and covers the breathable hole 104.

[0069] Specifically, by arranging the breathing membrane, when the power supply board 120 works, the heat generated by the power supply board 120 causes the gas in the cabin 111 to be heated, and when the gas pressure increases, the gas in the cabin 111 can be discharged to the outside of the power supply cabin 110 through the breathing membrane and the breathable hole 104. At the same time, the breathing membrane can play a waterproof role, which can prevent water and foreign matter in the external environment from entering the cabin 111 through the breathable hole 104 and the breathing membrane as much as possible.

[0070] Please refer to Figures 2-4 In an embodiment, the power supply cabin assembly 100 further comprises a sealing rubber ring 130 arranged between the bottom cover 112 and the cabin 111 to seal the gap between the bottom cover 112 and the cabin 111. Thus, water and foreign matter in the external environment can be prevented from entering the inside of the power supply cabin 110 through the gap between the bottom cover 112 and the cabin 111 as much as possible.

[0071] Please refer to Figure 4 and Figure 9 In an embodiment, the inner circumferential side of the cabin body 111 near one end of the bottom cover 112 is provided with an annular stepped surface 1112. Please refer to Figure 4 The bottom cover 112 has an annular boss 1121 protruding towards the outside of the cabin body 111.

[0072] The sealing rubber ring 130 includes a first end ring 131, a first side ring 132, a second end ring 133, and a second side ring 134. The first end ring 131 covers the end surface of the end of the cabin body 111 provided with the opening 111a and the end surface of the annular boss 1121, the first side ring 132 is connected with the inner circumferential edge of the first end ring 131 and located on the inner circumferential side of the annular boss 1121. One end of the second side ring 134 is connected with the first end ring 131 and located between the outer circumferential surface of the bottom cover 112 and the inner circumferential surface of the cabin body 111. The second end ring 133 is connected with one end of the second side ring 134 away from the first end ring 131, and the second end ring 133 is located between the annular stepped surface 1112 and the annular boss 1121.

[0073] In actual use, the side of the first end ring 131 away from the cabin body 111 is attached to the wall, and the first end ring 131 and the wall are sealed by sealing rubber, so as to prevent as much as possible the water in the external environment from entering the junction box embedded in the wall, thereby achieving waterproof of the junction box.

[0074] Since the second side ring 134 is located between the outer circumferential surface of the annular boss 1121 and the inner circumferential surface of the cabin body 111, it can seal the space between the outer circumferential surface of the annular boss 1121 of the bottom cover 112 and the inner circumferential surface of the cabin body 111. The second end ring 133 can seal the space between the annular stepped surface 1112 of the cabin body 111 and the annular boss 1121 of the bottom cover 112. The first side ring 132 is located on the inner circumferential side of the annular boss 1121, so as to prevent as much as possible the water from entering the inner circumferential side of the annular boss 1121.

[0075] Please refer to Figure 4 , Figure 5 and Figure 8 In an embodiment, the sealing rubber ring 130 further includes a protruding portion 135, one end of the protruding portion 135 is connected with the side of the first end ring 131 towards the cabin body 111 and located radially outside the second side ring 134.

[0076] The sealing rubber ring 130 is provided with a first wire passing groove 105, the first wire passing groove 105 is recessed from the side of the first end ring 131 away from the cabin body 111 to the inside of the protruding portion 135, and the first wire passing groove 105 penetrates the first end ring 131 and the protruding portion 135 along the radial direction of the sealing rubber ring 130.

[0077] The annular boss 1121 is provided with a second wire passing groove 106, which penetrates the annular boss 1121 along the radial direction of the annular boss 1121 and is in communication with the first wire passing groove 105.

[0078] The sidewall of the cabin body 111 is provided with a receiving groove 107, which penetrates the sidewall of the cabin body 111 along the radial direction of the cabin body 111 and receives the protruding part 135. The protruding part 135 is in sealing engagement with the groove wall of the receiving groove 107. In this way, the sealing rubber ring 130 can seal the power supply cabin 110 as much as possible at the first wire passing groove 105 and the second wire passing groove 106.

[0079] Please refer to Figure 5 The bottom cover 112 is provided with a wire passing hole 108, through which the wire connected to the power supply panel 120 can extend. The first wire passing groove 105 and the second wire passing groove 106 are used for the wire connected to the power supply panel 120 to pass through, and the wire is connected to the junction box on the wall, so as to realize the electrical connection between the power supply panel 120 and the junction box. A waterproof plug can be arranged at the wire passing hole 108, and the wire passes through the waterproof plug to extend out of the wire passing hole 108.

[0080] Please refer to Figure 5 and Figure 8 In an embodiment, the penetration direction of the first wire passing groove 105 is along the vertical direction and is located at the lower end of the sealing rubber ring 130.

[0081] Since the penetration direction of the first wire passing groove 105 is along the vertical direction and is located at the lower end of the sealing rubber ring 130, the penetration direction of the second wire passing groove 106 and the receiving groove 105 is also along the vertical direction and is located at the lower end of the sealing rubber ring 130. In this way, the first wire passing groove 105 and the second wire passing groove 106 not only have the function of passing wires, but also have the function of draining water. If water enters between the first end ring 131 and the wall due to poor sealing, the water entering between the first end ring 131 and the wall can be drained downward from the first wire passing groove 105 and the second wire passing groove 106 under the action of gravity, thereby minimizing or avoiding the water between the first end ring 131 and the wall from entering the junction box embedded in the wall.

[0082] Please refer to Figure 2 , Figure 3 and Figure 9 In an embodiment, the power supply cabin assembly 100 further comprises a mounting cylinder 140 and a connecting plate 150 and a second bolt (not shown). The connecting plate 150 is used for fixed connection with the junction box embedded in the wall.

[0083] The installation cylinder 140 is located inside the power supply cabin 110, and the extension direction of the installation cylinder 140 is along the axial direction of the power supply cabin 110. One end of the installation cylinder 140 is sealingly connected with the cabin body 111, and the other end of the installation cylinder 140 is sealingly connected with the bottom cover 112 through the waterproof silica gel ring 142. The inner circumferential side of the installation cylinder 140 has an annular supporting surface 141 facing away from the bottom cover 112. The shank of the second bolt is threaded through the installation cylinder 140 and is threadedly connected with the connecting plate 150, and the head of the second bolt abuts against the annular supporting surface 141.

[0084] Specifically, the installation cylinder 140 is hollow inside for the second bolt to pass through. The installation cylinder 140 and the cabin body 111 can be integrally formed. The outer circumferential side of the end of the installation cylinder 140 away from the bottom cover 112 is sealingly connected with the cabin body 111. The end of the installation cylinder 140 close to the bottom cover 112 is threaded through the bottom cover 112. The outer circumferential side of the end of the installation cylinder 140 close to the bottom cover 112 is sealingly connected with the bottom cover 112 through the waterproof silica gel ring 142. In this way, not only can the installation cylinder 140 be threaded along the axial direction in the power supply cabin 110, but also the inside of the installation cylinder 140 can be isolated from the inside of the power supply cabin 110, so that water from the external environment can be prevented from entering the inside of the power supply cabin 110 through the installation cylinder 140 as much as possible.

[0085] When connecting the power supply cabin assembly 100 with the junction box embedded in the wall, the connecting plate 150 can be first fixedly connected with the junction box.
