[0044] The present invention will be further described below with reference to the accompanying drawings.

[0045] An outdoor power supply includes a control board, a battery pack, and an inverter. Water can easily enter the outdoor power supply in rainy or snowy weather, causing the control board and components on the control board to burn out. To address this problem, existing outdoor power supplies employ waterproof measures to protect the outdoor power supply, such as sealing the outdoor power supply to improve its waterproof performance.

[0046] However, after the outdoor power supply has been running for a long time, the components on the control board will generate a lot of heat, and the sealing of the outdoor power supply will cause a lot of heat to accumulate inside the power supply, causing damage to the control board of the outdoor power supply and the components on the control board.

[0047] In order to solve the above technical problems, at least one embodiment of the present application provides a control panel assembly for use in a power supply device, including a shell 10, a fan 20, a control panel 30, a first ventilation structure 40 and a second ventilation structure 50; the fan 20 is arranged in the shell 10; the control panel 30 is arranged in the shell 10; the first ventilation structure 40 is arranged in the shell 10; the second ventilation structure 50 is arranged in the shell 10; wherein, when the fan 20 is in a non-heat dissipation state, the first ventilation structure 40 and the second ventilation structure 50 can block the shell 10 to prevent water in the external space of the shell 10 from entering the control panel; when the fan 20 is in a heat dissipation state, the first ventilation structure 40 and the second ventilation structure 50 can be connected to the external space of the shell 10, so that the first ventilation structure 40, the shell 10 and the second ventilation structure 50 jointly form a heat dissipation channel for air flow to dissipate heat from the control panel.

[0048] As can be seen from the above, by providing the first ventilation structure 40 and the second ventilation structure 50, the control panel assembly has both waterproof and heat dissipation functions, ensuring that the product can be used in relatively harsh working conditions and improving the versatility of the product. The first ventilation structure 40 and the second ventilation structure 50 are used to seal the housing 10 when in the non-heat dissipation state to improve the waterproof performance of the product and prevent water from the external space from entering the housing 10, thereby protecting the control panel 30; the first ventilation structure 40 and the second ventilation structure 50 are used to connect the housing 10 with the external space when in the heat dissipation state to form a flowing heat dissipation channel, thereby improving the heat dissipation performance of the product and avoiding damage to the control panel 30 caused by a large amount of heat accumulation. The first ventilation structure 40 and the second ventilation structure 50 are switched between the waterproof and heat dissipation functions by the heat dissipation state and the non-heat dissipation state of the fan 20 to improve the performance of the product.

[0049] like Figure 1 、 Figure 2 As shown, the control panel assembly is used in a power supply device, and includes a housing 10 , a fan 20 , a control panel 30 , a first ventilation structure 40 and a second ventilation structure 50 .

[0050] The housing 10 includes a main body 110 and a lateral projection 120. The lateral projection 120 is located on the side of the main body 110 and is connected to the main body 110. It should be noted that the housing 10 can be made of plastic. It should also be noted that the main body 110 and the lateral projection 120 can be integrally molded to achieve connection. It should also be noted that the lateral projection 120 is located above the main body 110.

[0051] The fan 20 is disposed in the main body 110 . It should be noted that the fan 20 is connected to the inner wall of the main body 110 , and the cross-sectional area of ​​the fan 20 is equal to the cross-sectional area of ​​the main body 110 .

[0052] The control board 30 is disposed within the main body 110, and the fan 20 is located above the control board 30. It should be noted that the control board 30 is a printed circuit board, and electronic components are mounted on the control board 30. The control board 30 can control the operation of the power supply device and the fan 20.

[0053] The first ventilation structure 40 is disposed within the main body 110 and is located below the control panel 30. The second ventilation structure 50 is disposed on the side protrusion 120 and is located above the fan 20. The lower first ventilation structure 40 and the higher second ventilation structure 50 enhance air flow within the housing 10, thereby improving ventilation and heat dissipation.

[0054] When the fan 20 is in the non-heat dissipation state, the first ventilation structure 40 and the second ventilation structure 50 can block the housing 10, thereby sealing the housing 10. It should be noted that the non-heat dissipation state refers to a state in which the fan 20 is not activated and the fan blades 20 are not rotating. The first ventilation structure 40 and the second ventilation structure 50 seal the housing 10 in the non-heat dissipation state, thereby improving the product's waterproof performance and preventing external water from entering the housing 10, thereby protecting the control board 30.

[0055] When the fan 20 is in the heat dissipation state, the first ventilation structure 40 and the second ventilation structure 50 can be connected to the external space of the housing 10, so that the first ventilation structure 40, the housing 10 and the second ventilation structure 50 together form a heat dissipation channel for air flow. It should be noted that the heat dissipation state refers to the state in which the fan 20 is started and the fan blades of the fan 20 are rotating. By connecting the housing 10 with the external space through the first ventilation structure 40 and the second ventilation structure 50 in the heat dissipation state, the fan 20 causes the heat on the control board 30 to flow upward in the heat dissipation state, enhancing the air flow and heat exchange in the housing 10, thereby forming a flowing heat dissipation channel, thereby improving the heat dissipation performance of the product and avoiding damage to the control board 30 caused by a large amount of heat accumulation.

[0056] The first and second ventilation structures 40, 50 provide the control panel assembly with both waterproofing and heat dissipation, ensuring the product's usability in relatively harsh operating conditions and improving its versatility. The first and second ventilation structures 40, 50 switch between waterproofing and heat dissipation by switching between the cooling and non-cooling states of the fan 20, thereby improving product performance.

[0057] like Figure 2As shown, in some embodiments, the bottom of the main body 110 has a first ventilation hole 130, and the minimum cross-sectional area of ​​the first ventilation hole 130 is smaller than the maximum cross-sectional area of ​​the first ventilation structure 40. It should be noted that the first ventilation hole 130 can be a cylindrical through hole or a frustum through hole. For example, the first ventilation hole 130 is a cylindrical through hole, and the cross-sectional area of ​​the first ventilation hole 130 is circular and the cross-sectional area is equal. By setting the cross-sectional relationship between the first ventilation hole 130 and the first ventilation structure 40, the first ventilation structure 40 can block the first ventilation hole 130, preventing the first ventilation structure 40 from falling out of the first ventilation hole 130.

[0058] When the fan 20 is in a non-heat dissipating state, the first ventilation structure 40 is at least partially located within the first ventilation hole 130, and the first ventilation structure 40 can block the first ventilation hole 130. It should be noted that the first ventilation hole 130 can be entirely located within the first ventilation hole 130. For example, when the first ventilation hole 130 is a frustum-shaped through hole that is larger at the top and smaller at the bottom, the first ventilation structure 40 can be entirely located within the first ventilation hole 130.

[0059] When the fan 20 is in the heat dissipation state, the first ventilation structure 40 can move toward the control board 30 to connect the housing 10 with the external space. It should be noted that when the fan 20 is in the heat dissipation state, the fan blades of the fan 20 rotate, and the fan blades drive the heat generated by the operation of the control board 30 to flow toward the top of the housing 10, making the air pressure below the fan 20 lower than the air pressure outside the housing 10, thereby forming a pressure differential. Under the action of the pressure differential, the first ventilation structure 40 moves upward, thereby creating a gap between the first ventilation structure 40 and the first ventilation hole 130, thereby connecting the housing 10 with the external space and forming a flowing heat dissipation channel.

[0060] In some embodiments, the cross-section of the first ventilation hole 130 is circular, and the first ventilation structure 40 is a spherical structure. It should be noted that the first ventilation hole 130 can be a cylindrical through hole or a truncated cone through hole. It should also be noted that when the first ventilation structure 40 is a spherical structure, the maximum cross-section of the first ventilation structure 40 is the plane where the diameter is located. It should also be noted that the first ventilation structure 40 can be a hollow spherical structure to reduce the weight of the first ventilation structure 40, thereby ensuring that the first ventilation structure 40 can be pressed against the inner wall of the first ventilation hole 130 under the action of gravity, while ensuring that the first ventilation structure 40 can move towards the direction close to the control panel 30 under the action of the pressure difference, so that the first ventilation hole 130 opens.

[0061] like Figure 1 、 Figure 2As shown, in some embodiments, the side wall of the side convex portion 120 away from the main body portion 110 has a second ventilation hole 140, and the second ventilation structure 50 is partially located in the second ventilation hole 140. It should be noted that the number of the second ventilation holes 140 is equal to the number of the second ventilation structures 50, and the second ventilation holes 140 correspond to the second ventilation structures 50 one by one, and the second ventilation structures 50 are located in the corresponding second ventilation holes 140. It should also be noted that the second ventilation holes 140 can be circular holes or polygonal holes, for example, Figure 1 As shown, the second ventilation hole 140 is rectangular.

[0062] When the fan 20 is in a non-heat dissipating state, the second ventilation structure 50 can block the second ventilation hole 140. The second ventilation structure 50 blocks the second ventilation hole 140 to prevent water from entering the housing 10 through the second ventilation hole 140.

[0063] When the fan 20 is in the heat dissipation state, the second ventilation structure 50 can be opened to connect the housing 10 with the outside space. It should be noted that when the fan 20 is in the heat dissipation state, the fan blades of the fan 20 rotate, driving the heat on the control board 30 to flow above the fan 20 to the side convex portion 120. The air pressure in the side convex portion 120 is greater than the air pressure outside the housing 10, forming a pressure differential. Under the action of the pressure differential, the second ventilation structure 50 opens, thereby connecting the housing 10 with the outside space. Moreover, since the first ventilation hole 130 is opened when the fan 20 is in the heat dissipation state, a flow heat dissipation channel is formed to quickly discharge the heat in the housing 10 to the outside space. As the air flows, the temperature and air pressure in the housing 10 return to normal, and the fan 20 is closed and enters the non-heat dissipation state. The first ventilation structure 40 falls into the first ventilation hole 130 under the action of gravity to block the first ventilation hole 130, and the second ventilation structure 50 closes to block the second ventilation hole 140.

[0064] like Figure 3 As shown, in some embodiments, the second ventilation hole 140 includes an outer hole section 1401 and an inner hole section 1402; the outer hole section 1401 is disposed on the outer surface of the side wall; the inner hole section 1402 is disposed on the inner surface of the side wall, and the inner hole section 1402 is connected to the outer hole section 1401; wherein the maximum cross-sectional width of the outer hole section 1401 is smaller than the maximum cross-sectional width of the inner hole section 1402, thereby forming a step surface between the outer hole section 1401 and the inner hole section 1402. It should be noted that the outer hole section 1401 can be a cylindrical hole section, the maximum cross-sectional width of the outer hole section 1401 being equal to the diameter of the outer hole section 1401; the inner hole section 1402 can also be a cylindrical hole section, the maximum cross-sectional width of the inner hole section 1402 being equal to the diameter of the inner hole section 1402. The step surface provides a stop for the installation of the second ventilation structure 50, thereby facilitating the installation of the second ventilation structure 50.

[0065] like Figure 3 As shown, in some embodiments, the second ventilation structure 50 includes two sealing members 510 disposed opposite each other. The sealing members 510 include an outer sealing segment 5101 and an inner sealing segment 5102. The outer sealing segment 5101 is disposed within the outer bore segment 1401 and abuts the stepped surface. The inner sealing segment 5102 is disposed within the inner bore segment 1402, with one end of the inner sealing segment 5102 connected to the outer sealing segment 5101. It should be noted that the other end of the inner sealing segment 5102 is located outside the inner bore segment 1402. It should also be noted that a gap may be provided between the outer sealing segment 5101 and the inner wall of the outer bore segment 1401 to provide space for the outer sealing segment 5101 to move under the influence of a pressure differential. A gap may also be provided between the inner sealing segment 5102 and the inner wall of the inner bore segment 1402 to provide space for the inner sealing segment 5102 to move under the influence of a pressure differential.

[0066] When the fan 20 is in a non-heat dissipation state, the two outer sealing segments 5101 abut against each other, and the two inner sealing segments 5102 at least partially abut against each other, thereby blocking the second ventilation hole 140. It should be noted that when the fan 20 is in a non-heat dissipation state, the two outer sealing segments 5101 abut against each other, and the sum of the cross-sections of the two outer sealing segments 5101 is greater than the cross-section of the inner hole segment 1402, thereby blocking the inner hole segment 1402. It should also be noted that the portions of the two inner sealing segments 5102 located within the inner hole segment 1402 abut against each other, and a gap is always present between the ends of the two inner sealing segments 5102 not located within the inner hole segment 1402.

[0067] When fan 20 is in the heat dissipation state, an outer gap is defined between the two outer sealing sections 5101, and an inner gap, communicating with the outer gap, is defined between the two inner sealing sections 5102, thereby connecting housing 10 to the outside. By connecting the inner and outer gaps, second ventilation structure 50 is opened, allowing heat from control panel 30 to be dissipated through the connected inner and outer gaps.

[0068] In some embodiments, the seal 510 is a silicone seal 510 or a rubber seal 510. The use of silicone or rubber materials to form the seal 510 not only ensures the sealing performance of the seal 510 and has good high and low temperature resistance, making it suitable for use in various working conditions, but also allows the silicone seal 510 and the silicone seal 510 to deform under the action of pressure difference, thereby ensuring that in the heat dissipation state, the two seals 510 no longer abut each other, forming a ventilation gap.

[0069] like Figure 2As shown, in some embodiments, the housing 10 includes a partition 150 connected to the side protrusion 120, and the partition 150 and the side protrusion 120 together form a waterproof groove 60; wherein, the second ventilation structure 50 is located above the partition 150. It should be noted that the partition 150 can be made of plastic, and the partition 150 and the side protrusion 120 can be integrally molded to achieve connection. Because the side protrusion 120 is located above the control board 30, to prevent water from flowing through the second ventilation hole 140 and damaging the control board 30, the waterproof groove 60 is provided to temporarily collect water entering the housing 10, thereby providing a waterproof effect.

[0070] like Figure 1 、 Figure 2 As shown, in some embodiments, a drainage hole 1201 is provided on the sidewall of the side protrusion 120 away from the main body 110. The drainage hole 1201 is located below the second ventilation structure 50 and is connected to the waterproof groove 60. It should be noted that the number of drainage holes 1201 is set according to actual needs and is not limited by this application. The drainage holes 1201 drain water temporarily stored in the waterproof groove 60, preventing the water level in the waterproof groove 60 from overflowing and flowing toward the control board 30, causing damage to the control board 30.

[0071] like Figure 4 As shown, at least one embodiment of the present application further provides a power supply device, comprising a housing 1, a battery 2 disposed in the housing 1, and a control panel assembly 3 as described in any embodiment of the present application, thereby having all the technical effects brought about by the technical solutions of the above embodiments. It should be noted that the power supply device includes but is not limited to an outdoor power supply. It should also be noted that a handle 4 is provided on the housing 1 to facilitate carrying the power supply device; a battery 2 compartment is provided in the housing 1, the battery 2 is located in the battery 2 compartment, and the control panel assembly 3 is connected to the battery 2 compartment.

[0072] While the present invention has been described with reference to preferred embodiments, various modifications may be made and equivalent components may be substituted without departing from the scope of the present invention. In particular, the various technical features described in the various embodiments may be combined in any manner, provided no structural conflicts exist.
