Description

Technical Field

[0001] This utility model relates to the field of membrane keypad installation technology, specifically a membrane keypad panel. Background Technology

[0002] Membrane buttons are tactile switch panels made of flexible thin film materials, widely used in industrial control equipment (such as CNC machine tools and PLC control panels), medical instruments (patient monitors and infusion pumps), home appliances (microwave ovens and washing machines), automotive electronics (center consoles and dashboards), consumer electronics (POS machines and game controllers), and military and aerospace equipment. Their core advantages include, but are not limited to:

[0003] 1) Lightweight and compact, with a thickness of only 0.1-0.5mm, saving more than 80% of space;

[0004] 2) High sealing performance, achieving IP65 to IP67 protection rating through hot pressing or gluing processes, providing dust and water resistance;

[0005] 3) Ultra-long lifespan: silicone contacts support 500,000 to 1,000,000 presses, far exceeding mechanical buttons;

[0006] 4) Low cost and easy mass production; screen printing and laser cutting processes reduce costs by 30% to 50%.

[0007] 5) Flexible customization, can integrate backlight, multi-layer circuit and pressure sensing functions;

[0008] In addition, membrane buttons support blind operation feedback (such as tactile / light cues), which performs well in harsh scenarios such as medical and military applications. In the future, combined with flexible electronics technology, they will further expand intelligent interactive applications. The installation methods of membrane button panels are also diversified, such as adhesive, magnetic, snap-fit, and screw fixing.

[0009] Taking screw-fixed membrane buttons as an example, the membrane button panel is fixed by multiple screws. During subsequent use, dirt and grime accumulate at the contact points between the screws and the membrane buttons, and the corrosion from the user's sweat causes the screws to rust. When replacing the membrane buttons later, it is inconvenient to remove the screws, and the connection between the two is not easy to clean. Impurities will accelerate the wear of the membrane buttons, causing the membrane buttons to wobble and affecting the performance. Utility Model Content

[0010] To address the aforementioned issues, this application provides a membrane keypad panel that solves the problem that some membrane keypad panels are fixed with multiple screws, which are not protected and are easily corroded by sweat, affecting subsequent disassembly.

[0011] A membrane keypad panel includes a keypad panel body with multiple screw holes extending through its edge. Multiple protective rings are fixedly installed on the top of the keypad panel body, and the protective rings are coaxially installed with the screw holes. A cover plate is slidably inserted into the periphery of adjacent protective rings.

[0012] In addition, the protective ring and cover plate are made of rubber, and the inner side of the cover plate is frosted.

[0013] In addition, a protective post is slidably inserted into the middle of the protective ring, and a magnet is fixedly installed at the bottom of the adjacent protective posts. The magnet is attached to the bottom of the button panel body.

[0014] In addition, a protective cover is movably installed on the top of the button panel body. Multiple slots are opened on the inner side of the protective cover. The inner side of the slots is smooth, and the cover plate is slidably installed on the inner side of the slots.

[0015] In addition, the protective cover is made of transparent and rigid materials.

[0016] In addition, the inner diameter of the protective ring is larger than the maximum outer diameter of the screw.

[0017] In addition, the button panel body and the outer side of the cover are both covered with an anti-corrosion coating.

[0018] The beneficial effects of this utility model are as follows:

[0019] The membrane keypad described in this utility model adopts multiple installation methods. During long-term use, the keypad body is fixed with screws, and a cover plate is used to cover the protective ring, screw holes, and screws to prevent the screws from being corroded by the sweat of the staff during subsequent use. This makes it easy to disassemble the screws and also makes it difficult for dirt to accumulate in the screw holes, reducing the wear rate and making the keypad body less prone to loosening.

[0020] For temporary use, staff simply place the button panel and magnet on the metal plate of the device, smooth the button panel, and it is ready to use. It is convenient, quick, and easy to disassemble and install.

[0021] It is also equipped with a protective mechanism. When not in use, staff can cover the top and outer perimeter of the button panel with a protective cover to prevent dust from falling onto the button panel. When needed, the protective cover can be removed for immediate use without cleaning, thus improving work efficiency. Attached Figure Description

[0032] To more clearly illustrate the technical solutions in the embodiments of this utility model or the prior art, the present utility model will be briefly introduced below in conjunction with the accompanying drawings and descriptions of the embodiments or the prior art. Obviously, the following description of the structure of the accompanying drawings is only some embodiments of this utility model. For those skilled in the art, other drawings can be obtained based on these drawings without creative effort. It should be noted that the description of these embodiments is used to help understand this utility model, but does not constitute a limitation on this utility model.

[0033] like Figure 2 , Figure 3 , Figure 4 As shown, this utility model embodiment provides a membrane keypad panel, including a keypad panel body 1. Multiple screw holes 2 are provided through the edge of the keypad panel body 1 for installing screws to fix the keypad panel body 1. Multiple protective rings 3 are fixedly installed on the top of the keypad panel body 1. The protective rings 3 are coaxially installed with the screw holes 2. A cover plate 4 is slidably inserted into the periphery of adjacent protective rings 3. The protective rings 3 and the cover plate 4 are made of rubber. The inner side of the cover plate 4 is frosted to increase the friction between the cover plate 4 and the protective rings 3, making it less likely to fall off under non-human force. The protective rings 3 and the cover plate 4 work together to reduce the possibility of the screw holes 2 and screws being corroded by sweat.

[0034] In this embodiment, during long-term use, the operator places the button panel body 1 in the installation area, screws into the screw holes 2 to fix the button panel body 1, and uses a cover plate 4 to cover the protective ring 3, screw holes 2, and screws to prevent the operator's sweat from corroding the screws during subsequent use. This also makes subsequent screw removal easier, prevents dirt and grime from accumulating in the screw holes 2, reduces wear, and prevents the button panel body 1 from loosening.

[0035] Furthermore, such as Figure 5 , Figure 6 As shown, a protective post 5 is slidably inserted into the middle of the protective ring 3, and a magnet 6 is fixedly installed at the bottom of the adjacent protective post 5. This is used for quick installation and removal of the button panel body 1 for short-term use. The magnet 6 is attached to the bottom of the button panel body 1.

[0036] In this embodiment, when used temporarily, the staff can place the button panel body 1 and the magnet 6 on the metal plate of the equipment and smooth the button panel body 1 for use. It is convenient, quick and easy to disassemble and install. The protective post 5 fills the screw hole 2 and the protective ring 3, which can reduce the possibility of the two being squeezed, deformed or damaged during transportation.

[0037] For long-term use, the protective post 5 and magnet 6 can be removed and recycled for reuse.

[0038] Furthermore, such as Figure 2 , Figure 4 , Figure 7 As shown, a protective cover 7 is movably installed on the top of the button panel body 1. Multiple slots 8 are provided on the inner side of the protective cover 7. The inner side of the slots 8 is smooth, which reduces the friction between the slots 8 and the cover plate 4. When the protective cover 7 is removed, the cover plate 4 will not be pulled off. The cover plate 4 is slidably installed on the inner side of the slots 8.

[0039] In this embodiment, when not in use, the staff covers the top periphery of the button panel body 1 with the protective cover 7, so that external dust is not easy to fall on the button panel body 1. When it is used later, the protective cover 7 can be removed and it can be used immediately without cleaning, which improves work efficiency. The cover plate 4 is inserted into the slot 8, which makes the protective cover 7 more stable.

[0040] Furthermore, such as Figure 7 As shown, the protective cover 7 is made of transparent and rigid material, which makes it convenient for staff to check the condition of the button panel body 1 inside the protective cover 7, such as the flashing of the indicator lights on the button panel body 1.

[0041] Furthermore, such as Figure 3 As shown, the inner diameter of the protective ring 3 is larger than the maximum outer diameter of the screw. When the screw is screwed into the screw hole 2, it will not come into contact with the protective ring 3, so the protective ring 3 will not be damaged.

[0042] Furthermore, such as Figure 3As shown, the outer sides of the button panel body 1 and the cover plate 4 are covered with an anti-corrosion coating to reduce the corrosive effect of sweat and extend the service life.

[0043] Specific working methods:

[0044] For long-term use, the staff places the button panel body 1 in the installation area, removes the protective post 5 and magnet 6, which can be recycled and reused, screws into the screw hole 2 to fix the button panel body 1, and uses the cover plate 4 to cover the protective ring 3, screw hole 2 and screws to prevent the staff's sweat from corroding the screws during subsequent use, making it easy to remove the screws, and also making it less likely for dirt to accumulate in the screw hole 2, reducing the wear rate, and making the button panel body 1 less likely to loosen.

[0045] When not in use, the staff will cover the top periphery of the button panel body 1 with the protective cover 7, so that external dust will not easily fall onto the button panel body 1. When it is needed for subsequent use, the protective cover 7 can be removed and it can be used immediately without cleaning, which improves work efficiency. The cover plate 4 is inserted into the slot 8, which makes the protective cover 7 more stable.

[0046] When used temporarily, staff can place the button panel body 1 and magnet 6 on the metal plate of the equipment and smooth the button panel body 1 before use. It is convenient, quick and easy to disassemble and install. The protective post 5 fills the screw hole 2 and the protective ring 3, which can reduce the possibility of compression deformation and damage during transportation.

[0047] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the scope of protection of this utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the scope of protection of this utility model.
