Description

Technical Field

[0001] The utility model relates to the technical field of membrane switches, in particular to an embedded surface-touch membrane switch. Background Art

[0002] The membrane switch is an operating system that integrates key functions, indicating elements, and instrument panels. It consists of four parts: panel, upper circuit, isolation layer, and lower circuit. When the membrane switch is pressed, the contacts of the upper circuit deform downward and contact and conduct with the plates of the lower circuit. When the finger is released, the contacts of the upper circuit rebound, the circuit is disconnected, and the loop triggers a signal. However, since the membrane switch is generally directly embedded in the corresponding position, there will be a certain gap between the membrane switch and the installed position. Some oil and dust can easily penetrate from the gap and easily cause a certain impact on the membrane switch. For this reason, we propose an embedded surface touch membrane switch. Utility Model Content

[0003] In view of the problems in the prior art, the utility model provides an embedded surface-touch membrane switch.

[0004] The technical solution adopted by the utility model to solve the technical problem is an embedded surface-touch membrane switch, comprising a plate frame, the inner side of the top open end of the plate frame is equipped with a soft membrane layer for protection, and the bottom surface of the plate frame is embedded with a membrane switch body that is in contact with the soft membrane, and the bottom surface of the plate frame is equipped with a bottom bracket for preventing falling off through screws;

[0005] The outer surface of the plate frame is provided with a groove that can be used for connection, and a silicone pad that can be used for leakage prevention is bonded to the inner side of the groove. The outer surface of the silicone pad is provided with a frame groove that can be used for connection, and there are multiple groups of frame grooves. Memory cotton strips are bonded to the inner side of the frame groove, and the top surface of the silicone pad is integrally constructed with an adhesive layer that can be used for connection.

[0006] By adopting the above technical solution, when installing the membrane switch, the membrane switch body can be conveniently embedded directly on the inner side of the plate frame, and the plate frame can be conveniently embedded in the corresponding position. At the same time, the soft film layer at the top open end of the plate frame can protect the membrane switch body. At the same time, the soft film layer is convenient for tensioning and pressing, which is convenient for controlling the membrane switch body and making the membrane switch body operate more stably.

[0007] When the panel frame is embedded, the silicone pad on the top of the panel frame is convenient for improving the stability of the panel frame during installation, and can seal the gap between the panel frame and the installation position. At the same time, the adhesive layer on the top of the silicone pad is easy to stick, thereby improving the tightness between the silicone pad and the installation position, thereby further improving the tightness between the two, which is convenient for reducing the leakage of oil and dust, and the silicone pad is easy to press back into place. Since the memory cotton strip is assembled on the inner side of the frame groove, it is convenient to improve the rebound performance of the silicone pad, thereby improving the elasticity of the silicone pad, and the tightness of the panel frame during installation is effectively improved.

[0008] Specifically, a sponge pad for protection is bonded to one side of the base close to the membrane switch body, and vertical holes for heat dissipation are provided on the top surface of the sponge pad and the outer peripheral surface of the base, and there are multiple groups of vertical holes.

[0009] By adopting the above technical solution, the sponge pad can reduce the damage caused by friction between the base and the membrane switch body. At the same time, the multiple groups of vertical holes can allow the membrane switch body between the base and the plate frame to dissipate heat, so that it can operate more stably.

[0010] Specifically, a filter layer that can be used for protection is bonded to the bottom surface of the base.

[0011] By adopting the above technical solution, the filter layer can help reduce the situation where dust penetrates from the vertical holes into the space between the bottom bracket and the plate frame.

[0012] Specifically, a groove for wiring is provided on a side surface of an outer circumference of the plate frame, and a rubber seat for protection is clamped inside the groove.

[0013] By adopting the above technical solution, the groove and the rubber seat cooperate with each other, which facilitates the protection of the connection wires of the membrane switch body.

[0014] Specifically, a rubber strip that can be used to prevent leakage is bonded between the silicone pad and the plate frame.

[0015] By adopting the above technical solution, the rubber strip can be easily assembled in the gap between the silicone pad and the plate frame, so as to seal and protect it and reduce the infiltration of dust and oil.

[0016] Specifically, the top surface of the plate frame is provided with arc grooves that can be used for connection, and there are multiple groups of arc grooves. The bottom surface of the silicone pad is integrally constructed with arc strips that fit and connect with the arc grooves, and there are multiple groups of arc strips.

[0017] By adopting the above technical solution, the arc strip and the arc groove are fitted and connected with each other, which facilitates improving the stability of the silicone pad after installation.

[0019] 1.

At the same time, the soft film layer at the open end of the top of the plate frame can protect the membrane switch body. At the same time, the soft film layer is convenient for tensioning and pressing, which is convenient for controlling the membrane switch body and enables the membrane switch body to operate more stably.

[0020] 2. The technical solution of the present application is designed with grooves, silicone pads, frame grooves, adhesive layers and memory foam strips. When the plate frame is embedded, the silicone pad on the top of the plate frame is convenient for improving the stability of the plate frame during installation, and can also seal the gap between the plate frame and the installed position. At the same time, the adhesive layer on the top of the silicone pad is convenient for adhesion, thereby improving the tightness between the silicone pad and the installed position, thereby further improving the tightness between the two, which is convenient for reducing the leakage of oil and dust. The silicone pad is convenient to press back into place, and since the memory foam strip is assembled on the inner side of the frame groove, it is convenient to improve the rebound performance of the silicone pad, thereby improving the elasticity of the silicone pad, and the tightness of the plate frame during installation is effectively improved.
