Description

Technical Field

[0001] The utility model relates to the technical field of switch devices, in particular to a key reset and positioning structure of a switch. Background Art

[0002] With the continuous development and rise of smart home and smart hotel fields at home and abroad, switches, as an important part of smart products, have evolved from wired connections to wireless connections, and their styles and structures are constantly being updated and replaced.

[0003] At present, most of the smart switches on the market use the button reset principle to control the on and off of the lights. The button reset usually uses the elastic force of a metal spring to achieve the reset function, and has no positioning effect. Because the spring is small and easy to tilt, it will lead to inadequate reset and stuck phenomenon, which greatly increases labor costs and material costs. Lack of positioning will also cause the button to swing in a large arc, causing friction between surfaces, resulting in button reset failure, affecting the normal use of the switch.

[0004] 1. Technical issues to be resolved

[0005] In order to overcome the shortcomings of the prior art, a switch button reset and positioning structure is proposed, which has a simple structure and can realize the reset and positioning function of the switch button.

[0006] (II) Technical solution

[0007] The utility model is implemented through the following technical scheme: the utility model proposes a switch button reset and positioning structure, including a plastic middle frame arranged on a switch panel, the plastic middle frame being snap-connected with a switch button, the switch button realizing directional positioning and rebound reset function along the vertical direction of the plastic middle frame through a reset positioning structure arranged on the plastic middle frame, the reset positioning structure comprising a plurality of reset springs and positioning holes arranged on the reset springs for positioning the switch button.

[0008] Furthermore, a plurality of hooks are arranged on the back of the switch button, and a slot suitable for the hooks is opened on the plastic middle frame.

[0009] Furthermore, the reset spring is arranged at the four corners of the plastic middle frame and is an integrated structure with the plastic middle frame. The reset spring includes an elastic bar formed by separating the grooves of the plastic middle frame. The tail of the elastic bar extends upward and is provided with a protruding structure. The positioning hole is circular and is provided on the protruding structure.

[0010] Furthermore, a positioning pin that fits the positioning hole is provided on the back of the switch button.

[0011] Furthermore, the plastic middle frame includes a plurality of key areas, and each key area is snap-connected with a switch key.

[0012] (III) Beneficial effects

[0013] Compared with the prior art, the utility model has the following beneficial effects:

[0014] The utility model mentions a switch button reset and positioning structure, in which a reset spring is provided on a plastic middle frame, and the reset spring and the plastic middle frame are an integrated structure, without the need to install additional components, thus avoiding the cumbersomeness of installing other reset parts; a positioning hole is provided on the reset spring, which can ensure the integrity of the switch button and the reset spring and play a reset function; when the switch button is pressed and released, its positioning pin is always in the positioning hole, thereby playing a positioning function for the switch button when it moves, thus avoiding the phenomenon of inadequate reset and jamming when using a metal spring.

[0020] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0021] like Figure 1-Figure 4A switch button reset and positioning structure is shown in the figure, a plastic middle frame 1 is fixedly arranged on the switch panel 7, the plastic middle frame 1 is provided with a plurality of key areas for installing switch buttons 2, 4 in this embodiment, a card slot 5 is opened on each key area of ​​the plastic middle frame 1, the switch button 2 is provided with a hook 4, the hook 4 extends into the card slot 5 to realize the connection between the switch button 2 and the plastic middle frame 1, each key area is provided with a reset positioning structure 3, the reset positioning structure 3 includes a reset spring piece 31 arranged at the four corners of the key area, the reset spring piece 31 and the plastic middle frame 1 are an integrated structure, the reset spring piece 31 includes a spring bar 311 formed by the slot of the plastic middle frame 1, and the spring bar 3 The tail 312 of the switch button 11 extends upwardly and is provided with a raised structure. The positioning hole 32 is circular and is provided on the raised structure. A space is left below the raised structure. A positioning pin 6 suitable for the positioning hole 32 is provided on the back of the switch button 2. The positioning pin 6 is inserted into the positioning hole 32 to achieve coupling connection with the plastic middle frame 1, thereby ensuring the balance of the switch button 2 when it moves in a direction perpendicular to the plastic middle frame 1. When the switch button 2 is pressed to move, the positioning pin 6 drives the tail 312 of the spring bar 311 to move downward for a distance, so that the contacts of the switch are connected. When the switch button 2 is released, due to the elasticity of the plastic, the spring bar 311 drives the switch button 2 to rebound and reset.
