Point switch

Abstract

The utility model discloses a point switch which comprises a function key shell, and one side of the function key shell is provided with a second touch panel. A guide part is arranged on one surface, facing the function key shell, of the second touch panel, and a guide part for guiding the guide part to slide directionally is arranged in the function key shell. Due to the fact that the second touch panel can stably and directionally move under the joint cooperation of the guide part and the guide part, the problem that the touch panel cannot accurately and sensitively enable the touch switch to be turned on and turned off due to the fact that the track is unstable when the touch panel moves is solved. The guide part is in contact with the arc surface arranged on the guide part through the arranged guide groove, so that the arc surface of the guide part is matched with the inner wall surface of the guide groove, and on one hand, the guide groove can be stably and reliably released from the guide part; and on the other hand, the sliding resistance of the guide groove on the arc surface is smaller. On the basis, the function key is simple in structure and convenient to use, and the sensitivity of the function key is improved.

Description

Technical Field

[0001] The utility model relates to the technical field of switch equipment, in particular to a point switch. Background Art

[0002] The touch switch is also called a key switch. When in use, the switch function is closed by applying pressure in the direction of the switch operation under the condition of satisfying the operating force. When the pressure is removed, the switch is disconnected. Its internal structure relies on the change of force on the metal spring to achieve on-off.

[0003] However, if the touch panel of the existing touch switch cannot move in a directional manner during the pressing process, the touch panel will deviate from the movement trajectory, resulting in the touch panel and the metal spring inside the function key not being able to stably and fully contact, thereby causing the touch switch to have a reduced sensitivity. Utility Model Content

[0004] The purpose of the utility model is to provide a point switch to solve the problems raised in the above background technology.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solution: a point switch, comprising a function key housing, and a second touch panel is provided on one side of the function key housing; a guide portion is provided on a side of the second touch panel facing the function key housing, and a guide portion for guiding the guide portion to slide in a directional manner is provided inside the function key housing.

[0006] As a preferred technical solution of the utility model: the guide portion contacts the arc surface provided on the guide portion through the provided guide groove.

[0007] As a preferred technical solution of the utility model: the guide part and the leading part are arranged in a strip shape.

[0008] As a preferred technical solution of the present utility model: a braking part is also provided on the second touch panel, and the braking part slides in a braking groove provided on the function key housing.

[0009] As a preferred technical solution of the present invention: a first touch panel having the same structure as the second touch panel is further provided on the other side of the function key housing.

[0010] As a preferred technical solution of the present utility model: a surface of the first touch panel and the second touch panel away from the function key housing is arranged in an arc shape.

[0011] By adopting the above technical solution, the beneficial effect of the utility model is that the second touch panel can move stably and directionally under the cooperation of the guide part and the guiding part, so as to solve the problem that the touch panel cannot accurately and sensitively prompt the touch switch to open and close due to the unstable trajectory of the touch panel when moving.

[0018] Embodiments of the present utility model are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present utility model, and should not be construed as limitations on the present utility model. In the description of the present utility model, it should be understood that the orientation or positional relationship indicated by the terms "upper", "lower", "front", "upper surface", etc. is based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on the present utility model.

[0019] See also Figure 1-5 The utility model provides an embodiment: a point switch, including a function key housing 1, and a second touch panel 3 is provided on one side of the function key housing 1; a guide portion 30 is provided on a side of the second touch panel 3 facing the function key housing 1, and a guide portion 5 for guiding the guide portion 30 to slide in a directional manner is provided inside the function key housing 1.

[0020] In summary, the second touch panel 3 can move stably and directionally under the cooperation of the guide portion 30 and the guide portion 5, so as to solve the problem that the touch panel cannot accurately and sensitively cause the touch switch to open and close due to the unstable trajectory of the touch panel when moving.

[0021] Furthermore, the guide portion 30 is in contact with the arc surface 6 provided on the guide portion 5 through the guide groove 32. Therefore, by utilizing the cooperation between the arc surface 6 of the guide portion 5 and the inner wall surface of the guide groove 32, the guide groove 32 can be stably and reliably released from the guide portion 5; and secondly, the sliding resistance of the guide groove 32 on the arc surface 6 is smaller.

[0022] Furthermore, since the guide portion 30 and the guide portion 5 are arranged in a strip shape, the guide portion 30 can be in full contact with the guide portion 5 throughout the entire running stroke, so as to avoid the phenomenon of control failure of the second touch panel 3 caused by the two falling off, for example, jamming during pressing and incomplete resetting during resetting.

[0023] On the basis of the above scheme, a braking portion 31 is further provided on the second touch panel 3, and the braking portion 31 slides in a braking groove 4 provided on the function key housing 1. Therefore, the cooperation between the braking portion 31 and the braking groove 4 can avoid the second touch panel 3 and the function key housing 1 from falling off after the external force disappears, without interfering with the normal pressing of the second touch panel 3.

[0024] In addition, since the other side of the function key housing 1 is further provided with a first touch panel 2 having the same structure as the second touch panel 3, one function key has two touch panels, so that the function key can control two circuits simultaneously.

[0025] Furthermore, since the first touch panel 2 and the second touch panel 3 are arranged in an arc shape on a surface away from the function key housing 1 , the outer end surface of the function key is circular, thereby optimizing its structure.

[0026] The embodiments of the present invention are described in detail above with reference to the accompanying drawings, but the present invention is not limited to the described embodiments. For those skilled in the art, various changes, modifications, substitutions and variations of these embodiments are made without departing from the principles and spirit of the present invention, and still fall within the scope of protection of the present invention.
