AI Technical Summary
Due to the size of the existing headset buttons, it is difficult for users to accurately trigger small switches when pressing the large button, and often fail to trigger them.
Design a key assembly, including buttons, pressing elastic plate, support plate and trigger switch. The pressing elastic plate consists of a fixed plate, a shrapnel and a press plate. The shrapnel is distributed on the fixed plate. The guide hole is provided on the press plate, and there is a guide shaft on the button. , the trigger switch is fixed on the support plate, and the bending and restoring force of the shrapnel ensures that the switch can be triggered accurately during pressing.
Regardless of the pressing position, pressing the elastic plate can accurately press to the trigger switch position, avoiding the occurrence of the situation where the switch cannot be triggered due to the large button area.

[0008] Compared with the prior art, the utility model has the following beneficial effects: no matter where the user presses the button, the elastic plate can be pressed accurately to the position of the trigger switch, and the situation where the trigger switch cannot be pressed accurately and fails to be triggered due to the large button area will not occur. BRIEF DESCRIPTION OF THE DRAWINGS
[0009] In order to more clearly illustrate the technical solutions in the embodiments of the present invention, the following briefly introduces the drawings required for use in the description of the embodiments. Obviously, the drawings described below are only some embodiments of the present invention. For those skilled in the art, other drawings can be obtained based on these drawings without creative labor:
[0010] Figure 1 This is a schematic diagram of the overall structure of a key assembly of the utility model;
[0011] Figure 2 This is a schematic diagram of the explosion structure of a key component of the utility model Figure 1 ;
[0012] Figure 3 This is a schematic diagram of the explosion structure of a key component of the utility model Figure 2 . DETAILED DESCRIPTION
[0013] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0014] In the present invention, unless otherwise clearly specified and limited, the terms "install", "connect", "connect", "fix" and the like should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; 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. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.
[0015] See also Figure 1-Figure 3 A key assembly includes a key 2, a pressing elastic plate 3, a supporting plate 4 and a trigger switch 5. The key 2 is movably arranged in a shell 1. The pressing elastic plate 3 is fixed on the shell 1 and one side is opposite to the key 2. The pressing elastic plate 3 includes a fixing plate 31, a plurality of springs 32 and a pressing plate 33. The fixing plate 31 is fixed on the shell 1. One end of the spring 32 is connected to the fixing plate 31, and the other end is bent toward the key 2 and connected to the pressing plate 33. A guide hole 331 is provided on the pressing plate 33. A guide shaft 22 is provided on the key 2, and the guide shaft 22 is inserted into the guide hole 331. The supporting plate 4 is fixed on the shell 1. The trigger switch 5 is fixed on the supporting plate 4. The trigger switch 5 is opposite to the pressing plate 33 (the trigger switch 5 and the key 2 are respectively located on both sides of the pressing plate 33).
[0016] The principle of the utility model is as follows: when the button 2 is pressed, the button 2 presses the pressure plate 33 inwardly, and the downward pressure is concentrated at the center of the pressure plate 33 (because the center of the pressure plate 33 is at the greatest distance from the spring 32), and the spring 32 bends inwardly until the pressure plate 33 presses the trigger switch 5 to achieve triggering; after releasing, the button 2 is reset due to the restoring force of the spring 32.
[0017] In the present invention, the number of the spring pieces 32 is preferably 3. The three spring pieces 32 are equidistantly distributed on the fixing plate 31 in a circle.
[0018] As a further improvement of the present invention, a protrusion 34 is provided in the middle of the pressure plate 33, and the protrusion 34 is opposite to the trigger switch 5. When the user presses, the protrusion 34 can touch the trigger switch 5 more accurately, avoiding the occurrence of failure to trigger when pressed.
[0019] In the present invention, the key 2 is movably arranged in the housing 1. Specifically, the housing 1 is provided with a through hole 11, the housing 1 is provided with a T-shaped step 12 at the position of the through hole 11, and the edge of the key 2 is provided with a T-shaped step 21. The T-shaped step 12 and the T-shaped step 21 cooperate with each other. The movable structure design is an existing common design.
[0020] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, the elements defined by the statement "comprise a ..." do not exclude the presence of other identical elements in the process, method, article or device including the elements.
