Description

Technical Field

[0001] The utility model relates to the field of elevator buttons, in particular to a mechanical induction elevator button. Background Art

[0002] Chinese Utility Model Publication No. CN216054408U discloses a non-contact sensing and mechanical triggering composite button, including a shell, a pressing component, a sensing component and a screw cover. The sensing component includes a first circuit board and a second circuit board arranged in a stacked manner, the first circuit board is electrically connected to the second circuit board, a switch and a sensing lamp bead are provided on the first circuit board, and the sensing lamp bead extends into the sensing lamp hole; the screw cover is sleeved on the outer periphery of the shell and is detachably connected to the shell. This composite button integrates non-contact sensing and traditional mechanical pressing functions. The two functions can be used independently of each other, enriching the button function. The double-layer circuit board effectively reduces the size of the button structure and improves the portability. This composite button realizes mechanical touch triggering through the photoelectric structure, but due to the short life of the photoelectric sensing module and the high maintenance cost, the after-sales repair cost is increased.

[0017] In the description of the present invention, it should be noted that the terms "up", "down", "left", "right", "inside", "outside", etc. indicate directions or positional relationships based on the directions or positional relationships shown in the accompanying drawings. The above description is simplified for the convenience of describing the present invention, and does not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, it cannot be understood as a limitation on the present invention.

[0018] The singular forms "a", "an", "said" and "the" used in the specification include plural forms unless otherwise indicated. The terms "include", "comprises" and "comprising" used in the specification indicate the presence of the claimed features, but do not exclude the presence of one or more other features.

[0019] In the specification, when an element is referred to as being “on,” “fixed” to, “connected to,” “engaged to,” or the like, the element may be directly on, fixed to, connected to, engaged to, or contacting the other element, or intervening elements may be present.

[0020] It will be understood that although the terms "first," "second," etc. may be used herein to describe different elements, these elements should not be limited by these terms. These terms are merely used to distinguish one element from another. Thus, a first element may be referred to as a second element without departing from the teachings of the present invention.

[0021] The following describes exemplary embodiments of the present application with reference to the accompanying drawings. However, it should be understood that the present application can be presented in many different ways and is not limited to the embodiments described below. It should also be understood that the embodiments disclosed herein can be combined in various ways to provide many additional embodiments. In all figures, the same reference numerals represent the same elements or elements with the same function.

[0022] Figure 1 The figure shows the overall structure of the induction elevator button, which mainly includes a frame consisting of an outer frame 10 and a base 60, and a pressing component 30, a light guide plate 40 and a circuit board 70 arranged in the frame.

[0023] This button has two triggering modes: mechanical and touch-sensitive. Mechanical triggering is primarily achieved through a push-type switch 72 provided on a circuit board 70. The circuit board 70 is fixed to the base 60, and the push-type component 30 is placed within the space enclosed by the outer frame 10 and the base 60. Mechanical triggering is achieved by pressing the push-type switch 72 from above. In a preferred embodiment, the button is designed as a long strip, with the push-type switches 72 along its long sides, ensuring that the user can mechanically trigger the button normally regardless of whether they press the left or right side of the button.

[0024] Inductive triggering is primarily achieved by connecting a circuit board 70 to a touch mechanism located on the surface of the pressing component 30, forming a circuit path. Specifically, a metal touchpad 20 is attached to the surface of the pressing component 30, and an elastic conductor 50 is provided on the circuit board 70. One end of the elastic conductor 50 is soldered to the circuit board 70, while the other end contacts the touchpad 20, achieving connectivity. Correspondingly, a first through-hole 31 is provided in the pressing component 30, through which the elastic conductor 50 passes to connect to the touchpad 20.

[0025] In one embodiment, the elastic conductor 50 is composed of a metal spring 52 and a guide rod 51. A third through-hole 72 is provided on the circuit board 70 for inserting and securing the guide rod 51. The metal spring 52 is mounted on the guide rod 51 to prevent bending during compression, and one end of the metal spring 52 is soldered to the circuit board 70. The metal spring 52 also provides elastic restoring force to the pressing component 30 through the touchpad 20 adhered to the pressing component 30, helping the pressing component 30 return upward after being squeezed.

[0026] In addition, a light guide plate 40 is disposed between the pressing member 30 and the circuit board 70. Because the pressing member 30 is provided with a hollowed-out letter logo, the light source is evenly transmitted through the light guide plate 40. The light guide plate 40 has a second through-hole 32 for the elastic conductor 50 to pass through, and the second through-hole 32 is coaxial with the first through-hole 31.
