Description

Technical Field

[0001] The utility model relates to a switch for realizing the vertical triggering function of a button, belonging to the field of automotive parts. Background Art

[0002] With the rapid development of modern automotive technology, in order to meet the usage requirements of customers, many lighting switches are set as backlight buttons, enabling customers to smoothly turn on the lighting switch under various circumstances. When there is a vertical requirement for the switch backlight and the button, generally two mutually perpendicular circuit boards are used as the functional implementation method for connecting the LED and the conductive rubber or the micro switch; this increases the structural space layout of the switch and also increases the development cost of the switch. Content of the Utility Model

[0003] The purpose of the utility model is to overcome the disadvantages and deficiencies existing in the prior art, and to provide a switch for realizing the vertical triggering function of a button.

[0004] A switch for realizing the vertical triggering function of a button includes a housing and a button. An installation cavity is provided inside the housing. The button includes a pushing portion that horizontally extends into the installation cavity. The pushing portion is linked with a push rod that can vertically move inside the installation cavity. The bottom of the push rod abuts against a pressing block. The pressing block is linked with a conductive rubber. The conductive rubber is electrically connected to a circuit board. The button drives the push rod to vertically move inside the installation cavity through a pushing action, and then drives the pressing block to press the conductive rubber to be connected with the circuit board to form a circuit path. Through the cooperation of the push rod and the pressing block, the linear motion is converted into a vertical motion, simplifying the complex motion conversion process in the traditional shift mechanism, reducing the requirement for the space structure, and at the same time reducing the number of circuit boards. The two circuit boards are simplified into one circuit board, reducing the production and manufacturing cost.

[0005] Preferably, a limiting groove is provided inside the housing. Rotating rods extending into the limiting groove and being in limiting connection therewith are provided on both sides of the push rod. When the button is pressed, the rotating rods can rotate away from the limiting state of the limiting groove and vertically move to push the pressing block, adjusting the force arm distance between the pressing point of the push rod and the rotating rods, and increasing or decreasing the button force value and the stroke size. When the button is not pressed, the limiting state of the rotating rods and the limiting groove can ensure that the push rod is not slightly touched and pressed, preventing situations such as accidental touch.

[0006] Preferably, a first moving groove is provided on the housing. The pushing portion is slidably installed in the first moving groove. The end of the pushing portion abuts against the push rod. The push rod is slidably installed in the first moving groove. The first moving groove can limit the pushing portion and the push rod while enabling the pushing portion and the push rod to slide, pressing the pressing rod.

[0007] Furthermore, the first moving groove communicates with a second moving groove. The ejector rod further includes a pressing rod extending into the second moving groove. The bottom of the pressing rod abuts against the pressing block. The pressing rod is driven by the ejector rod to move in the installation cavity to press the pressing block, converting the horizontal movement of the button into a vertical movement, improving the utilization efficiency of space and reducing costs.

[0008] Furthermore, a buckle cover is provided on the outer shell above the first moving groove, which is used to protect the internal components from external environmental interference, improving the use effect and service life.

[0009] Preferably, the pressing block is provided with a groove, and the bottom of the pressing rod is arranged in a protruding shape in matching with the groove, making the touch during the pressing process smoother and more natural, reducing the sense of abruptness, improving the comfort of the user during operation. The matching design of the pressing block and the groove can achieve more efficient force transmission, reduce the friction between components, and make the relative movement between components smoother.

[0010] Furthermore, the groove is located in the middle of the pressing block, and the force can act on the pressing block more evenly, thus effectively triggering the conductive rubber and reducing the force loss.

[0011] Preferably, the conductive rubber includes a separately arranged first conductive part and a second conductive part. The first conductive part is provided with a card slot, and the bottom of the pressing block is provided with a block matching the card slot; a through hole is provided on the pressing block, and a convex block is provided on the second conductive part in a protruding manner, and the convex block extends into the through hole to be engaged with it. When the button pushes the ejector rod and the ejector rod presses down the pressing block, the first conductive part and the second conductive part are simultaneously triggered with the conductive discs on the circuit board. The connection of the card slot and the block, and the through hole and the convex block enables the pressing block to be tightly connected, better triggering the electrical signal.

[0012] The beneficial effects of the present utility model are as follows: By the cooperation of the ejector rod and the pressing block, the linear motion is converted into a vertical motion, simplifying the complex motion conversion process in the traditional shifting mechanism, reducing the requirement for the space structure, and at the same time reducing the number of circuit boards. The two circuit boards are simplified into one circuit board, reducing the production and manufacturing costs. BRIEF DESCRIPTION OF THE DRAWINGS
