Description

an elevator button

technical field

The utility model relates to a button switch, in particular to an elevator button.

Background technique

The elevator button is mainly composed of a shell with an opening, a light-transmitting plate installed in the shell, a force-transmitting component and a circuit board assembly, wherein the circuit board assembly is located at the bottom of the shell, and the circuit board assembly includes a light-emitting component connected by a conductor and As for the switch component, the light-transmitting plate is slidably installed in the casing above the circuit board, and a force transmission component is arranged between the light-transmission plate and the circuit board, and the force transmission component is opposite to the switch component. When the user presses the light-transmitting plate, the light-transmitting plate moves downward, and transmits the action force to the switch part through the force transmission part, so that the switch part is turned on or off, and the command signal is sent to the elevator. At the same time, the light-emitting part is controlled to be turned on or off. Disconnect, to show the user his operating status. At present, the force transmission part generally adopts a plunger, such as a light-emitting button disclosed in Chinese patent 200520062980.4, the upper end of the plunger is stepped, and a boss with holes is arranged on the bottom surface of the light-transmitting plate, and the upper end of the plunger is inserted into the boss in the hole. Since the thickness of the light-transmitting plate at the boss is greater than that of other parts, and the plunger will also block the light entering the light-transmitting plate, when the light-emitting component emits light, the corresponding light-transmitting plate at the contact point of the plunger and the light-transmitting plate will There are black spots or dim light in the position, which will affect the display effect.

Contents of the invention

The purpose of the utility model is to provide an elevator button that does not appear black spots and emits uniform light when emitting light, so as to improve the display effect of the elevator button.

In order to achieve the above object, the technical solution adopted by the utility model is:

An elevator button, comprising a housing with an opening, a circuit board assembly, a force transmission component, and a light-transmitting assembly arranged in the housing, wherein the circuit board assembly includes a light-emitting component and a switch component connected through a conductor, and the light-transmitting component The component is slidably arranged on the side of the circuit board component close to the opening, a force transmission component is provided between the light-transmitting component and the switch component, and the light-transmitting component is close to the side of the force transmission component The side of the said force-transmitting component is a plane, and the end of said force-transmitting component close to the light-transmitting component has a top protruding toward one side of the light-transmitting plate.

With this technical scheme, the thickness of the light-transmitting component is uniform everywhere, which avoids black spots and other undesirable phenomena at the position of the light-transmitting plate component corresponding to the contact between the force-transmitting component and the light-transmitting plate component when the light-emitting component emits light, and improves the display. Effect.

The surface of the top is an arc surface. With this structure, the force transmission part and the light-transmitting component are in point-surface contact, and the contact area is small, which prevents the force-transmission component from blocking the light entering the light-transmitting plate component, and the button emits light more uniformly, further improving The display effect of the button is improved; moreover, because the surface of the top of the force transmission part is a curved surface, it is ensured that when any point on the surface of the light-transmitting plate component is pressed, the force can be correctly transmitted and the switch part is touched, which greatly improves the performance of the product.

The force transmission part is a translucent soft part, and when the force of the user pressing the light-transmitting plate is too large, the soft part can play a buffering role to protect the switch part. A clamping step is provided at one end of the force transmission component close to the circuit board, and a groove is provided on the end surface of the end, and a pressure column is provided at the center of the bottom of the groove, and the pressure column is opposite to the switch component. . When the height of the pressure column is constant, the diameter of the pressure column has a great influence on the force transmission of the force transmission component. If the diameter of the pressure column is too small, the strength of the pressure column is not enough to trigger the switch component. If the diameter of the pressure column is too large , cannot play the role of cushioning, and has an impact on the life of the switch component, so the diameter of the pressure column is preferably 1.5 to 2.5 mm. The diameter of the pressure column is related to the deformed length.

The light-transmitting component includes a light-transmitting plate and a light-diffusing plate arranged overlappingly, and the light-transmitting plate is located on a side of the light-diffusing plate close to the opening. The light emitted by the light-emitting part is diffused by the light-diffusing plate first, and then evenly emitted to the light-transmitting plate, so that the button emits light evenly and improves the display effect. The surfaces on both sides of the light diffusion plate are concavo-convex surfaces, which can not only enhance the light diffusion effect of the light diffusion plate, but also increase the friction between the light diffusion plate, the force transmission component and the light-transmitting plate.

The light-transmitting assembly also includes a light-tight mounting seat, on which a mounting hole matched with the light diffusion plate is arranged, and the light diffusion plate is placed in the mounting hole and snapped into the mounting seat. buckle connection. By installing the light-diffusing plate in the light-tight mounting seat, it can ensure that there is no light leakage around the light-diffusing plate, which not only makes the light intensity uniform to all parts of the light-transmitting plate, but also makes the button emit light evenly and improves the display effect of the button. Moreover, the utilization rate of light is also improved. A spring mounting post is provided on the side of the mounting seat close to the circuit board assembly, and a return spring is sleeved on the spring mounting post. When the pressing force of the operator disappears, the installation seat and the light-transmitting plate return to the initial state under the action of the spring.

The light-emitting component is a patch LED, and the space occupied by the patch LED is small, and the thickness of the button switch is reduced.

Compared with the prior art, the utility model has the advantages of avoiding the appearance of black spots on the light-transmitting plate when the button emits light, and improving the display effect; in addition, it has the advantages of simple and reasonable structure and convenient assembly.
