Description

Technical Field

[0001] This application relates to the technical field of waterproofing for control modules, and more particularly to a waterproof component for a power box control module. Background Art

[0002] Currently, the control of lighting lamps is mainly through button operations on the power box. Common power box buttons are made of silicone materials, and the internal PCB circuit board is triggered by the buttons to achieve control functions.

[0003] In order to fix the relative position of the silicone button and the PCB circuit board, generally, the method of opening holes in the silicone button is adopted. The positioning posts fixedly arranged on the PCB circuit board cooperate with the holes to achieve the positioning of the silicone button.

[0004] However, this design has poor waterproof performance. When the housing encounters water, moisture easily flows through the key holes of the housing to the silicone button, and then along the openings or holes on the silicone button, and further flows onto the PCB circuit board, resulting in short circuits or damage to the PCB circuit board. Utility Model Content

[0005] In order to improve the waterproof performance of the silicone button, this application provides a waterproof component for a power box control module.

[0006] This application provides a waterproof component for a power box control module, adopting the following technical solutions:

[0007] A waterproof component for a power box control module includes an inner housing and an inner waterproof pad. The circuit board is fixedly installed inside the inner housing. The inner waterproof pad is installed in the inner housing for waterproofing the circuit board. The inner housing is provided with an object-passing hole adapted to the component and allowing the component to pass through. The inner waterproof pad is provided with a waterproof groove surrounding the component. A waterproof strip is fixedly arranged on the inner side of the inner housing and is adapted to be inserted into the waterproof groove. The waterproof strip surrounds the edge of the object-passing hole.

[0008] By adopting the above technical solutions, by setting the inner housing and the inner waterproof pad, and making the inner waterproof pad surround the component to form a waterproof groove, the direct contact of moisture with the circuit board is effectively isolated, thereby improving the waterproof performance of the power box control module. The object-passing hole of the inner housing allows the component to pass through, and the design of the waterproof groove and the waterproof strip ensures that even if moisture enters the outer housing, it will not penetrate into the inner housing and the circuit board, preventing the risk of short circuits or circuit board damage.

[0009] Optionally, it further includes an outer housing and an outer waterproof pad. The inner housing is fixedly connected to the outer housing. The outer waterproof pad is installed between the inner housing and the outer housing. The outer waterproof pad is provided with a first component hole adapted to the component. The outer housing is provided with a second component hole adapted to the component.

[0010] By adopting the above technical solution, the outer shell and the outer waterproof pad are added to form a double-layer waterproof structure, further enhancing the waterproof effect.

[0011] Optionally, a water stop strip surrounding the second component hole is fixed on the outer shell.

[0012] By adopting the above technical solution, by fixing the water stop strip on the outer shell to surround the second component hole, the waterproof ability of the outer shell is further improved. The water stop strip can effectively prevent moisture from entering the interior of the outer shell through the second component hole, enhancing the sealing performance and waterproof effect of the entire power box control module.

[0013] Optionally, a limiting convex ring adapted to the outer waterproof pad is provided around the outer peripheral side of the inner shell.

[0014] By adopting the above technical solution, the limiting convex ring on the periphery of the inner shell is adapted to the outer waterproof pad, ensuring the stability of the fixation between the inner and outer shells, preventing the decline of the waterproof performance caused by the relative movement of the outer shell and the inner shell, and at the same time making the installation of the outer waterproof pad more firm.

[0015] Optionally, a chamfer is provided at the edge of the object passing hole of the inner shell.

[0016] By adopting the above technical solution, the chamfer design reduces the sharpness of the hole edge, preventing unnecessary cutting or abrasion of the waterproof material when the component passes through, and ensuring that the waterproof structure remains intact during long-term use.

[0017] Optionally, a groove is provided on the side of the outer waterproof pad facing the inner shell.

[0018] By adopting the above technical solution, the groove can achieve the purpose of weight reduction, material saving and reducing the contact area. It effectively prevents the problem that some parts are high and some parts are low, affecting the waterproof performance.

[0019] Optionally, a positioning convex ring surrounding the object passing hole is fixed on the outer side of the inner shell, and the positioning convex ring surrounds the edge of the object passing hole.

[0020] By adopting the above technical solution, the positioning convex ring on the outer side of the inner shell is fixed on the edge of the object passing hole, which can not only enhance the positioning accuracy of the component, but also play an auxiliary waterproof role to prevent moisture from penetrating along the edge of the component.

[0021] Optionally, the waterproof strip and the inner shell are of an integrally formed structure.

[0022] By adopting the above technical solution, the waterproof strip and the inner shell are integrally formed, ensuring the stability of the waterproof strip and not easy to fall off. At the same time, it simplifies the assembly process of the components and improves the production efficiency.

[0023] In summary, the present application includes at least one of the following beneficial effects:

[0024] 1. Since the present invention adopts the design of an inner housing and a double waterproof pad, it effectively prevents moisture from contacting the PCB circuit board through the keys or other components, thus significantly improving the waterproof performance and safety of the power box.

[0025] 2. The outer housing and the water stop strip preferably adopted in the present invention further enhance the waterproof effect. BRIEF DESCRIPTION OF THE DRAWINGS

[0037] The following further describes the present application in detail with reference to the drawings.

[0038] An embodiment of the present application discloses a waterproof component for a power box control module. Referring to Figure 1 , 2 , the waterproof component includes an outer housing 3, an inner housing 1, an outer waterproof pad 4, and an inner waterproof pad 2. The inner waterproof pad 2 is made of an elastic waterproof material such as silicone or rubber, is installed in the inner housing 1, and closely adheres to the inner side wall of the inner housing 1. The circuit board 6 is fixedly installed in the inner housing 1 and presses the inner waterproof pad 2 in the inner housing 1 for controlling various functions of the power box.

[0039] The inner housing 1 is installed in the outer housing 3, and the outer waterproof gasket 4 is pressed between the inner housing 1 and the outer housing 3 to further improve the waterproof performance of the power supply box.

[0040] Referring to Figure 2 , 3 , the inner housing 1 is provided with an object-passing hole 11 adapted to the component and through which the component passes. The component in this embodiment is a control module such as a button 22. The edge of the object-passing hole 11 is provided with a chamfer to ensure the smooth passing of the button 22. The inner waterproof gasket 2 has a silicone button 22 and an opening through which the display screen on the circuit board 6 passes.

[0041] Referring to Figure 3 , 4 , a waterproof groove 21 surrounding the button 22 is provided on the inner waterproof gasket 2. A waterproof strip 12 adapted to be inserted into the waterproof groove 21 is integrally injection-molded on the inner side of the inner housing 1. The waterproof strip 12 surrounds the edge of the object-passing hole 11 and is closely combined with the waterproof groove 21 to form an effective waterproof barrier to prevent moisture from seeping in through the gap between the button 22 and the inner housing 1.

[0042] When the user presses the button 22, the button 22 triggers the PCB circuit board 6 to achieve the control function. Due to the presence of the inner waterproof gasket 2 and the waterproof strip 12, even if the outer shell gets wet, moisture cannot enter the interior through the gap between the button 22 and the housing, thus effectively protecting the circuit board 6 from moisture.

[0043] Referring to Figure 3 , a first component hole 41 adapted to the button 22 and other related components is provided on the outer waterproof gasket 4 for the button 22 to pass through. At the same time, a second component hole 31 adapted to the button 22 and other related components is also provided on the outer housing 3. The button 22 passes through the first component hole 41 and the second component hole 31 in sequence and extends out of the surface of the outer housing 3 for operation.

[0044] Referring to Figure 3 , a water-stop strip 32 is also fixed on the outer housing 3. The water-stop strip 32 surrounds the edge of the second component hole 31. When the outer waterproof gasket 4 is pressed between the inner housing 1 and the outer housing 3, the water-stop strip 32 further presses tightly against the outer waterproof gasket 4. When moisture attempts to seep in through the second component hole 31, the water-stop strip 32 can effectively prevent the entry of moisture, thereby further improving the waterproof effect.

[0045] Referring to Figure 2, a limiting convex ring 13 adapted to the outer waterproof pad 4 is provided around the outer peripheral side of the inner housing 1, and a positioning convex ring 14 is fixed to the outer side of the inner housing 1 along the edge of the object passing hole 11 to surround the object passing hole 11. Both the limiting convex ring 13 and the positioning convex ring 14 are fixed to the inner housing 1 by integral injection molding. The positioning convex ring 14 and the limiting convex ring 13 provide a physical constraint, enabling the outer waterproof pad 4 to be accurately installed in a predetermined position, and also helping to maintain a tight fit between the outer waterproof pad 4 and the housing, thereby enhancing the waterproof performance.

[0046] Referring to Figure 3 , grooves 5 are formed on the inner sides of the inner waterproof pad 2 and the outer waterproof pad 4. The grooves 5 can achieve the purpose of reducing weight, saving materials and reducing the contact area. Effectively prevent the problem that some parts of the components are high and some are low, which affects the waterproof performance.

[0047] The implementation principle of this embodiment is as follows:

[0048] When the user presses the button 22, the button 22 triggers the circuit board 6 through the object passing hole 11 to achieve the control function. Due to the existence of the inner waterproof pad 2 and the waterproof strip 12, and the outer housing 3 and the outer waterproof pad 4, that is, the double housing and the double waterproof pads, even if the outer housing gets wet, it is difficult for water to enter the interior through the gap between the button 22 and the housing, thus effectively protecting the circuit board 6 from moisture.

[0049] The above are all the preferred embodiments of this application. The protection scope of this application is not limited accordingly. Therefore, all equivalent changes made according to the structure, shape and principle of this application should be covered within the protection scope of this application.
