Description

Technical Field

[0001] The utility model belongs to the field of switch structure design, and particularly relates to a starting switch. Background Art

[0002] Push-to-start on a vehicle is operated using a button or key on the vehicle. This function allows the vehicle's engine to start without inserting the key and turning it. During the startup process, the vehicle's electronic system automatically checks various parameters to ensure the normal operation of the engine and other equipment.

DETAILED DESCRIPTION

[0020] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0021] It should be noted that all directional indications in the embodiments of the present invention (such as up, down, left, right, front, back, etc.) are only used to explain the relative position relationship, movement status, etc. between the components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly. In the present invention, unless otherwise clearly specified and limited, the terms "connection", "fixed", etc. should be understood in a broad sense. For example, "fixed" can be a fixed connection, a detachable connection, or an integral whole; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements, unless otherwise clearly defined. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to the specific circumstances.

[0022] In addition, the technical solutions between the various embodiments can be combined with each other, but they must be based on the fact that ordinary technicians in this field can implement them. When the combination of technical solutions is mutually contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by this utility model.

[0023] The start switch structure provided by the embodiment of the utility model is as follows Figures 1 to 5As shown, it includes a shell 1, a button 2, a touch block 3 and a switch circuit board 4; the shell 1 has a cavity that passes through from top to bottom, the touch block 3 can be moved up and down and is arranged in the upper part of the shell 1, the button 2 is fixed to the upper end of the touch block 3, and has a pressing plate portion 21 covering the upper end of the touch block 3 and a surrounding plate portion 22 extending downward from the periphery of the pressing plate portion 21, the surrounding plate portion 22 is annular and surrounds the outside of the shell 1; the switch circuit board 4 is arranged at the bottom of the shell 1 and is covered with a rubber pad 40 on the upper part of the switch circuit board 4, and the button 2 can be connected to the upper end of the touch block 3 by snapping. In this embodiment, a panel portion 22 is provided on the button 2, and the panel portion 22 can block the gap between the button 2 and the upper end of the shell 1 from the side, thereby preventing dust and water from entering the interior of the shell 1 through the gap. In addition, the rubber pad 40 covers the switch circuit board 4 from above to prevent dust and water entering the shell 1 from contacting the switch circuit board 4, thereby enhancing the dust and water resistance of the switch and effectively improving the performance of the start switch. When in use, the finger presses the pressing plate portion 21 downward to push the touch block 3 downward, thereby triggering the switch structure on the switch circuit board 4.

[0024] Furthermore, a plurality of contact groups are provided on the upper surface of the switch circuit board 4, each contact group including two contacts 41 spaced apart. The rubber pad 40 is made of conductive rubber and has a column portion 42 at a position corresponding to each contact group. When the button 2 is pressed, the column portion 42 is squeezed by the pressure block 3, thereby connecting the two contacts 41 of each contact group. During use, after the pressure block 3 is pressed downward, the column portion 42 is fully squeezed to connect the two contacts 41. When the pressure applied to the pressure block 3 is removed, the column portion 42 moves upward and resets, and the electrical connection between the two contacts 41 in each contact group is disconnected.

[0025] like Figures 3 to 5 As shown, the center of the touch block 3 is provided with a through cavity 31 running through from top to bottom. The through cavity 31 is a conical structure that is thick at the top and thin at the bottom. A lamp bead 43 is provided on the switch circuit board 4 just below the through cavity 31. The lamp bead 43 is preferably a SMD LED lamp bead; a light-transmitting portion is provided on the press plate portion 21. When installed and used, the light emitted by the lamp bead 43 passes through the through cavity 31 and then passes through the light-transmitting portion, making the light appear bright; the light-transmitting portion can be set to text, English or graphic symbols.

[0026] In some embodiments, a positioning groove 421 is provided at the upper end of the column portion 42, and a positioning column 32 is provided at the lower end of the touch-pressure block 3 to cooperate with the positioning groove 421. The positioning groove 421 cooperates with the positioning column 32 to play a positioning role, ensuring the position accuracy of the positioning column 32.

[0027] like Figures 3 to 5As shown, a guide slot 11 extending in the up-down direction is provided on the inner wall of the shell 1, and a guide block 33 cooperating with the guide slot 11 is provided on the edge of the touch block 3. The guide slot 11 cooperates with the guide block 33 to guide and limit the up-down movement of the touch block 3; the lower end of the touch block 3 is installed by the upper port of the shell 1, and is resisted by an elastic inner snap 12 to prevent the touch block 3 from separating upward from the shell 1. The elastic inner snap 12 is provided on the inner wall of the shell 1. During the process of installing the touch block 3 into the shell 1, the elastic inner snap 12 is pressurized and deformed. After the touch block 3 is installed in place, the elastic inner snap 12 is reset to form a stop limit for the touch block 3.

[0028] like Figure 3 As shown, a bottom cover 5 is installed below the switch circuit board 4 in the housing 1, and a stop boss 13 is provided on the inner wall of the housing 1. The switch circuit board 4 is installed through the lower port of the housing 1. The edge of the rubber pad 40 is pressed between the stop boss 13 and the switch circuit board 4. The bottom cover 5 is fixed to the housing 1 and presses against the switch circuit board 4. The bottom cover 5 serves to stop and limit the switch circuit board 4 so that the switch circuit board 4 is reliably fixed.

[0029] In order to facilitate the quick and reliable installation of the starting switch, an elastic external snap buckle 14 is provided on the outer wall of the shell 1. During installation, the shell 1 is placed in the mounting hole, and the installation is achieved by the elastic external snap buckle 14 cooperating with the edge of the mounting hole. The installation is convenient and reliable. Preferably, the number of the elastic external snap buckles 14 can be set to two, three or four.

[0030] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any modifications or substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed in the present invention should be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be based on the scope of protection of the claims.
