Description

Technical Field

[0001] The utility model relates to the technology of silica gel field, in particular to a silica gel keypad. Background Art

[0002] The remote control is a wireless transmitter that allows operators to remotely control the machine to perform various operations. The principle of the remote control is to encode the key information through modern digital coding technology, and transmit light waves through infrared diodes. The light waves are converted into electrical signals by the infrared receiver of the receiver, and then decoded by the processor, and the corresponding instructions are demodulated to achieve the required operation requirements of the control set-top box and other equipment.

[0003] After pressing the corresponding button, some remote controllers control the corresponding mechanical device to perform a certain function. At this time, the indicator light under the button will work and light up and transmit the light to the outside through the button. When the operator observes the button is lit, he can clearly know what state the corresponding mechanical device is currently in or what function it is performing. However, due to the advantages of heat resistance and cold resistance, silicone keys are widely used in electronic calculators, remote controllers, computer keyboards, etc. However, silicone is a light-transmitting material. When the indicator light under a button is working and shining, it is easy to transmit light to the adjacent button and transmit light from the adjacent button to the outside, thereby misleading the operator and causing inconvenience to production. Therefore, it is necessary to propose a new solution to improve the above problem. Utility Model Content

[0004] In view of this, the utility model aims to solve the deficiencies in the prior art and its main purpose is to provide a silicone button which can effectively solve the problem that when the indicator light under a button of the existing silicone button is working and lighting, it is easy to transmit light to the adjacent buttons and transmit light from the adjacent buttons to the outside world, thereby misleading the operator and causing inconvenience to production.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A silicone key, comprising a body, the body is made of a light-transmitting material, a keycap is convexly formed on the upper surface of the body, a groove is concavely formed on the lower surface of the body, the groove is located directly below the keycap, and a convex column extends downward from the top end of the groove; a positioning hole is opened at the front end of the body, and an opaque layer is coated on the peripheral side of the keycap to prevent the light emitted by the indicator light from being transmitted from the peripheral side of the keycap.

[0007] As a preferred solution, the side surfaces of the body are concave to form limiting grooves to prevent the body from being displaced during transportation when installed in the shell of the remote control.

[0008] As a preferred solution, a relief groove is recessed at the rear end of the main body. The housing of the remote control is mostly fixed and installed by screws, and the relief groove is designed to avoid the installation position of the screws.

[0009] As a preferred solution, there are multiple keycaps and correspondingly, there are also multiple slots, each of which is located directly below the corresponding keycap, and a protrusion extends downward from the top end of each slot.

[0010] As a preferred solution, the protrusion extends downward from the center of the top surface of the slot.

[0011] As a preferred solution, the main body is provided with a fixing groove, the inner wall surface of the fixing groove is convex to form an extension groove, the main body is installed in the shell of the remote control, and then packed for transportation. During the transportation and handling process, the remote control may flip over, and the main body will also flip over in the shell of the remote control. Therefore, a fixing groove is provided to be plugged and fixed with a fixing column in the shell to prevent the position of the main body from shifting up and down. The design of the extension groove is compatible with the fixing column, which can effectively increase the contact area between the main body and the fixing column, and increase the interference force of the fixing column on the main body.

[0012] As a preferred solution, the light-proof layer is made of a black light-proof material, and the black light-proof material has a stronger light-proof performance.

[0013] Compared with the prior art, the utility model has obvious advantages and beneficial effects. Specifically, it can be seen from the above technical solution that:

[0014] The silicone button is installed in the shell of the remote control, the keycap is exposed outside the shell through the remote control, and the indicator light of the substrate is located in the slot. When the operator presses the corresponding keycap to control the operation of the mechanical equipment, the corresponding indicator light is lit, and the light is projected through the upper end surface of the keycap, and the surrounding side surface of the keycap is coated with an opaque layer. The light cannot pass through the opaque layer and is transmitted outward from the adjacent keycap, thereby avoiding misleading the operator and bringing convenience to production.
