Therefore, they should not be construed as limitations of the present invention.
[0037] The technical solution of the present invention will be further described below with reference to the accompanying drawings and specific embodiments.
[0038] Please see Figures 1 to 4 A waterproof display switch module is disclosed, comprising a base 1, an encoding unit 2, and a housing assembly 3. The housing assembly 3 is sleeved on the encoding unit 2. The encoding unit 2 is mounted on the base 1 and can slide up and down relative to the base 1. When the encoding unit 2 is pressed, the entire encoding unit 2 moves downward under the guidance of the base 1.
[0039] The housing assembly 3 includes a housing body 31, a transparent cover plate 32, and a waterproof double-sided adhesive 33. The top surface of the housing body 31 is provided with a sealing groove, the waterproof double-sided adhesive 33 is installed in the sealing groove, the transparent cover plate 32 covers the housing body 31 and the waterproof double-sided adhesive 33, and the edges of the housing body 31 are rounded.
[0040] The encoding unit 2 includes a display component 21. The display component 21 includes a display screen 211, a screen bracket 212, and a PCBA 213. The display screen 211 is correspondingly arranged with the transparent cover plate 32, the PCBA 213 is installed inside the screen bracket 212, and the display screen 211 is covered on the screen bracket 212.
[0041] Specifically, in practical use, the transparent cover 32 is attached to the outer shell 31 using waterproof double-sided adhesive 33. The outer shell assembly 3 covers the coding unit 2. The edges of the outer shell 31 are rounded, allowing water to flow downwards along the outer shell 31, preventing water from entering the product and achieving a waterproof function. Furthermore, it effectively prevents dust accumulation on the upper surface of the outer shell 31. The rounded edge design effectively disperses stress when the outer shell is subjected to localized impacts or scratches, preventing stress concentration that could cause the outer shell to crack and improving its service life.
[0042] PCBA213 receives command signals from the product control terminal and drives the display screen 211 to work. The display screen 211 is set to correspond with the transparent cover 32. Users can see the operation status of the selected function through the transparent cover 32 without the need for an additional display screen, thus improving the ease of use of the switch module.
[0043] Furthermore, the display component 21 also includes a diaphragm 214, which is attached to the display screen 211.
[0044] Furthermore, the encoding unit 2 also includes a rotating bracket assembly 22 and a base bracket assembly 23, with the rotating bracket assembly 22 rotatably mounted on the base bracket assembly 23 and the screen bracket 212 mounted on the rotating bracket assembly 22.
[0045] The rotating bracket assembly 22 includes a brush 221 and a rotating bracket 222. The brush 221 is disposed on the rotating bracket 222 and contacts the PCBA 213 and rotates on the PCBA 213.
[0046] In one optional embodiment, the brush 221 has a through hole, and a fastener is provided on the rotating bracket 222. The fastener passes through the through hole to fix the brush 221 to the rotating bracket 222. The fastener can be a screw or a bolt.
[0047] The rotating bracket 222 is located between the screen bracket 212 and the base bracket assembly 23. The screen bracket 212 and the base bracket assembly 23 are locked together by screws 24. The screen bracket 212, the base bracket assembly 23 and the PCBA 213 do not rotate. The outer shell 31 drives the rotating bracket 222 to rotate together. The PCBA 213 is fixed below the screen bracket 212. The brush 221 is fixed on the rotating bracket 222. The rotating bracket 222 drives the brush 221 to rotate. The PCBA 213 and the brush 221 rotate relative to each other to generate an encoded signal. The PCBA 213 feeds the encoded signal back to the product control terminal. The product control terminal controls the driving components inside the product to start working.
[0048] In an optional embodiment, the base support assembly 23 includes a base support 231 and a spring 232, with the spring 232 disposed on the base support 231. The surface of the rotating bracket 222 that contacts the spring 232 is a wave-shaped surface, and the spring 232 cooperates with the wave-shaped surface to generate a rotary gear feel. The rotation of the outer casing 31 generates a rotary gear feel and outputs an encoded signal. The entire product structure is simple and easy to assemble.
[0049] Furthermore, the spring piece 232 is a C-shaped component, with both ends of the spring piece 232 fixed to the base bracket 231, and an arc-shaped protrusion provided in the middle position of the spring piece 232.
[0050] The wave-shaped surface on the rotating bracket 222 includes multiple curved surfaces, and the arc-shaped protrusion slides on the wave-shaped surface and is locked between two adjacent curved surfaces according to the corresponding gear position.
[0051] Traditional button operation offers poor mechanical feedback and tactile experience, and its UI interaction is relatively simple. Some higher-end home appliances use hollow encoders to replace button operation to improve the tactile feel, but since hollow encoders do not have button confirmation functionality, an additional push-button switch function is required.
[0052] In an optional embodiment, PCBA213 includes a PCB board and a switch. The switch is attached to the PCB board, and a tip is provided on the base 1. When the encoding unit 2 is pressed down, the switch contacts the tip and outputs the pressing signal through the tip.
[0053] Furthermore, a spring 4 is provided inside the base 1, and the spring 4 is located between the base 1 and the switch. When the encoding unit 2 is pressed down, the spring 4 is compressed.
[0054] The base 1 remains stationary, while the encoding unit 2 is assembled and fitted with the base 1. The PCBA213 and the base 1 can slide up and down relative to each other. When the encoding unit 2 is pressed, the entire encoding unit 2 moves under the guidance of the base 1. The tip contacts the switch, generating a pressing sensation. Simultaneously, the switch is activated by the pressure from the tip, completing the output of the pressing signal. During the downward pressing of the encoding unit 2, the spring 4 is compressed, further enhancing the pressing sensation.
[0055] In one alternative implementation, PCBA213 includes a surface mount base with an opening for mounting a wire harness that connects to the product terminal. The opening facilitates easy access of the wire harness into the surface mount base, resulting in a compact and simple connection that helps minimize product size and optimize cost.
[0056] In summary, the switch module of this embodiment includes a base 1, a housing assembly 3, a display assembly 21, a rotating bracket assembly 22, and a base bracket assembly 23. A transparent cover 32 is attached to the housing 31. The rotating bracket 222 is located between the screen bracket 212 and the base bracket 231, which are locked together by threads. When the housing 31 is rotated, the rotating bracket 222 rotates to select the corresponding position. Pressing the transparent cover 32 causes the encoding unit 2 to slide up and down relative to the base 1, bringing the switch into contact with the tip and outputting a press signal to the product control terminal. The PCBA 213 receives the command signal from the product control terminal and drives the display screen 211 to display information. Waterproof double-sided adhesive 33 is provided between the housing 31 and the transparent cover 32, making the housing assembly 3 waterproof. The switch module of this embodiment is a multi-functional button integrating waterproofing, display, pressing, and rotation, offering high compatibility and a simple design, thus improving the ease of use of the product.
