Detailed Embodiments
[0020] The following further describes the present utility model in detail with reference to the accompanying drawings and specific embodiments. In order to describe the technical solution clearly and completely, the following embodiments are selected for description; the following embodiments are part of the embodiments of the present utility model; all other embodiments obtained on the basis of this application without creative efforts belong to the protection scope of the present utility model.
[0021] In the following embodiments, it should be noted that the orientation or positional relationships such as "upper", "lower", "left", "right", "inner", "outer", "top / bottom", etc. are all based on the orientation or positional relationships shown in the accompanying drawings. It is only for the convenience of clearly describing this embodiment, rather than indicating or implying that the device or element referred to must have a specific orientation, so it cannot be understood as a limitation to this application. At the same time, "first" and "second" in the embodiments are only used for the purpose of distinguishing descriptions, and do not represent indicating or implying relative importance.
[0022] As Figures 1-4 shown, the specific embodiment of the present utility model relates to a waterproof elevator button. The main structure of the waterproof elevator button includes a hollow housing 1 that is open front and back. The housing is designed to be hollow, which is convenient for the arrangement of internal components and waterproof treatment. At the top of the hollow housing 1, a button part 2 is fixed, which is used for passengers to press to trigger the operation instruction of the elevator.
[0023] At the bottom of the hollow housing 1, a substrate 3 with a switch is fixed. The substrate 3, as the core part of the circuit, is responsible for receiving the instruction from the button part 2 and transmitting it to the elevator control system. In order to ensure the waterproof performance, a waterproof cover 4 is provided between the substrate 3 and the button part 2.
[0024] On the side of the waterproof cover 4 facing the button part 2, a plurality of fixing grooves 41 are provided. These fixing grooves 41 are used to cooperate with the convex columns 21 at the bottom of the button part 2. An elastic member 6 (such as a spring or an elastic rubber ring) is sleeved outside the convex column 21. The elastic member 6 enables the button part 2 to automatically reset when no external force is applied. The cooperation mode between the fixing groove 41 and the convex column 21 can adopt interference fit or threaded connection to ensure the firmness of the connection and the waterproof performance.
[0025] In the middle of the waterproof cover 4, a buffer part 42 is provided. The buffer part 42 is provided with an elastic protrusion 421 facing the direction of the substrate 3. When the button part 2 is pressed, the contact point 22 at its bottom will contact the elastic protrusion 421, thereby triggering the switch on the substrate 3. This design not only plays a buffering role but also ensures reliable contact of the contact points.
[0026] In order to further enhance the waterproof performance, a plurality of protruding stoppers 11 are provided on the inner wall of the hollow housing 1, and hook portions 12 are provided between the stoppers 11. A plurality of engaging portions 23 are provided at the bottom edge of the button portion 2. When the button portion 2 is inserted into the hollow housing 1, its bottom is blocked by the stoppers 11 to limit its downward depth, and at the same time, the engaging portions 23 at the edge are limited by the hook portions 12 to prevent the button portion 2 from detaching from the hollow housing 1.
[0027] In addition, a ring plate 43 is further extended in the direction of the substrate 3 by the buffer portion 42. The ring plate 43 completely covers the outside of the touch switch, further improving the waterproof effect. At the same time, a sealing ring 5 is provided between the waterproof cover 4 and the substrate 3. The sealing ring 5 is closely attached to the outer surface of the substrate 3 and the edge of the inner wall surface of the waterproof cover 4, ensuring the sealing between the two.
[0028] In order to provide better visual effects and user experience, the waterproof cover 4 is made of a transparent material. The substrate 3 is provided with a plurality of LED elements 31 at the edge of the touch switch. The light energy of these LED elements 31 can pass through the waterproof cover 4 to emit, providing clear indication signals for passengers.
[0029] On the substrate 3, a power output terminal 32 electrically connected to the touch switch is also provided. In order to facilitate the access of the power cord, a through hole 13 for installing the power output terminal 32 is provided on the hollow housing 1.
[0030] An installation hole 14 is provided at the bottom of the hollow housing 1 of the present application, and the substrate 3 is fixed to the bottom of the hollow housing 1 by screws or other fasteners passing through the installation hole 14.
[0031] The above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any minor modifications, equivalent replacements, and improvements made to the above embodiments based on the technical essence of the present invention shall be included within the protection scope of the technical solution of the present invention.
