Abstract

A switch device includes a housing unit with a first limiting surface, a switch assembly, a pressing piece and an elastic buffer unit mounted on the housing unit. The switch assembly has keys. The lower pressing piece is movably penetrated through the housing unit and has a second limiting surface. The elastic buffer unit elastically pushes against the button and the pressing member for pressing the button. The elastic force of the elastic buffer unit drives the pressing member to move away from the switch assembly. A maximum distance is formed between the first limit surface and the second limit surface, which is smaller than the maximum compression amount of the elastic buffer unit. Using the design of the elastic buffer unit, the key is maintained to be pressed down with the elastic force of the elastic buffer unit, instead of directly pressing the key, thereby prolonging the service life of the switch assembly.

Description

switchgear

The new model relates to a switch, in particular to a durable switch device.

One of the current ways to modulate the output audio of the electronic musical instrument is to electrically connect the effector to the electronic musical instrument, and set buttons or knobs on the effector so that the user can adjust the volume, audio, and / Or lengthen the time to output audio...etc.

Generally speaking, a button on the effector can be a tact switch, which can be electrically connected to the audio processing circuit of the effector when pressed, so as to modulate the corresponding output audio. Since commercially available tact switches have predetermined specifications, usually the minimum tactile force is 150g, which is suitable for finger pressing to operate the keys. However, when the user plays the musical instrument, they can only use their feet to step on the buttons of the effector, which is likely to cause the stepping force to be much larger than the minimum force of the touch switch, resulting in a shortened service life of the touch switch.

Accordingly, it is an object of the present invention to provide a switchgear that overcomes at least one of the disadvantages of the prior art.

Therefore, the novel switch device includes a housing unit, a switch assembly, a lower pressing piece, and an elastic buffer unit.

The housing unit extends along a longitudinal direction and has a first limiting surface.

The switch assembly has a switch body mounted on the housing unit, and a button that can be pressed and disposed on the switch body.

The lower pressing piece is movably passed through the housing unit along the longitudinal direction, and is spaced apart from the switch assembly, and has a second limiting surface.

The elastic buffer unit is elastically pressed between the button and the pressing member of the switch assembly to press the button when pressed down, and the elastic buffer unit provides an elastic force to drive the pressing member to move move away from the switch assembly.

A maximum distance is formed between the first limiting surface of the housing unit and the second limiting surface of the pressing member, the elastic buffer unit has a maximum compression amount, and the maximum distance is smaller than the maximum compression amount.

The utility model has the following functions: by utilizing the design of the elastic buffer unit, the user is prevented from directly pressing down the button, and the button is pressed down by the elastic force of the elastic buffer unit. On the other hand, use the maximum distance between the first limit surface and the second limit surface The design of the distance less than the maximum compression amount of the elastic buffer unit maintains the elastic buffer unit to use its elastic force to press the button, so as to avoid the situation that the pressing force on the button is too much larger than the minimum touch force. Thereby, the service life of the key is effectively prolonged.

The abutting area 312 that expands outward and is located below the abutting seat 13 and a limiting groove surface 313 which is recessed upward from the bottom side to define a limiting groove 314 . The penetration area 311 has a first maximum width W1. The diameter and width of the abutting area 312 is larger than the inner diameter of the abutting seat 13 , and has a second auxiliary abutting surface 315 which is annular and faces the first auxiliary abutting surface 124 at an upper and lower interval. The pressing portion 32 is generally cylindrical, has a second maximum width W2 larger than the first maximum width W1, and a second limiting surface 321 that is annular and faces downward. The diameter and width of the pressing portion 32 is larger than the inner diameter of the abutting seat 13 , and does not penetrate into the abutting seat 13 and is exposed to the housing unit 1 .

When the pressing member 3 moves upward to the abutting area 312 abutting against the bottom edge of the abutting seat 13 , it is limited, which is the highest point of the pressing member 3 moving upward relative to the housing unit 1 . , a maximum distance D is formed between the first limiting surface 133 and the second limiting surface 321 ; when the pressing member 3 moves downward until the second limiting surface 321 abuts against the first limiting surface 133 , It is the lowest point of the downward movement of the pressing member 3 relative to the housing unit 1 .

The elastic buffer unit 4 elastically presses against the switch assembly 2 and the pressing member 3 , and includes a pressing block 41 which rests against the top side of the button 22 and is located in the base housing 12 , and an elastic top The elastic pressing member 42 abuts against the top side of the pressing block 41 and the limiting groove surface 313 of the through portion 31 . The elastic pressing member 42 is a compression spring with a narrow upper portion and a lower width, and the top portion is limited to the limiting groove 314 and has a maximum compression amount and an elastic force. The elastic force constantly drives the pressing member 3 to move away from the switch assembly 2 . The pressing block 41 has a circular pressing surface 411 facing downward. The pressing surface 411 Under the elastic force of the elastic pressing member 42 , it is pressed against the pressing surface 221 of the button 22 . The area of the pressing surface 411 is not smaller than the area of the pressing surface 221 . The maximum compression amount is greater than the maximum distance D between the first limiting surface 133 and the second limiting surface 321 . In addition, the design of the elastic pressing member 42 is narrow at the top and wide at the bottom to ensure that the elastic pressing force of the elastic pressing member 42 is evenly and stably applied to the button 22 through the pressing block 41, and the elastic pressing member 42 is prevented from being damaged. The situation of force dislocation.

Referring to FIGS. 1 and 5 , when the pressing member 3 is not pressed in FIG. 6 , the pressing member 3 is supported upward by the elastic pressing member 42 until the abutting area 312 abuts against the abutting seat 13 and is located at the highest point (as shown in Figure 5). At this time, the button 22 is not pressed so that the switch assembly 2 is in the second state.

When the user wants to operate the effector, the pressing member 3 can be pressed down by hand or foot. During the downward movement of the pressing member 3 , the elastic pressing member 42 is elastically compressed, and the elastic force is transmitted through the elastic pressing member 42 , and the pressing block 41 is moved down by the elastic force to press the button 22 . When the elastic force for pressing the button 22 provided by the elastic force buffer unit 4 is greater than the minimum touch force of the button 22, the switch assembly 2 is switched to the first state, and the effector is activated to modulate the output audio for specific sound effect processing.

Because the switch device 10 uses the elastic force of the elastic force buffer unit 4 to press the button 22 , instead of the user directly applying force to press, the effect of buffering the pressing force can be achieved. In this way, the button 22 will not be subjected to excessive pressing force, avoiding pressing When the pressure is much larger than the minimum triggering force, the service life of the switch assembly 2 is effectively increased.

On the other hand, the maximum distance D between the first limiting surface 133 and the second limiting surface 321 is smaller than the maximum elastic compression amount of the elastic pressing member 42 . Therefore, when the pressing member 3 is pressed down to the lowest point (as shown in FIG. 6 ), the elastic pressing member 42 can still be elastically compressed, so as to ensure that the elastic buffer unit 4 is in the process of being pressed down by the pressing member 3 . Can buffer the user's force.

After use, the user no longer presses the pressing member 3, the pressing member 3 is pushed up and reset to the highest point by the elastic force of the elastic pressing member 42, and the button 22 is no longer pressed by the elastic pressing member 42. The elastic force is pressed to switch back to the second state.

In other variations of this embodiment, the first and second states can also be interchanged: when the button 22 is pressed by the elastic buffer unit 4, it is in the second state; when the button 22 is not pressed, it is in the second state. In this first state, it depends on the actual usage requirements.

Referring to FIG. 7 to FIG. 9 , it is a second embodiment of the novel switch device 10 . The second embodiment is similar to the first embodiment, except that the switch device 10 further includes an auxiliary buffer elastic member 5 . The auxiliary buffer elastic member 5 is a compression spring, which is sleeved on the elastic pressing member 42 at radial intervals and elastically abuts against the first auxiliary pressing surface 124 of the base housing 12 and the first auxiliary pressing member 3 . Between the two auxiliary pressing surfaces 315 . The auxiliary buffer elastic member 5 has an elastic force, and the elastic force drives the pressing member 3 to move in the direction away from the base housing 12 constantly.

With the design of the auxiliary buffer elastic member 5 , the force of the user pressing the lower pressure member 3 can be distributed between the elastic buffer unit 4 and the auxiliary buffer elastic member 5 . Therefore, the amount of pressing force exerted on the pressing member 3 not only presses the button 22 elastically through the elastic buffering unit 4, but also can be buffered by the elastic force of the auxiliary buffering elastic member 5, thereby improving the resistance of the switch device 10 to the button 22. Cushioning capacity for the amount of downforce applied.

To sum up, the switch device 10 of the present invention utilizes the design of the elastic buffer unit 4 and the housing unit 1 , so that the button 22 of the switch assembly 2 is pressed down by the elastic force of the elastic buffer unit 4 instead of being used. The user directly exerts force to press down, which can prolong the service life of the button 22 . Furthermore, the maximum distance D between the first limiting surface 133 and the second limiting surface 321 is smaller than the maximum compression amount of the elastic pressing member 42 to ensure that the button 22 is only pressed by the elastic force of the elastic buffer unit 4 . In addition, the design of the auxiliary buffer elastic member 5 can further disperse the force value of the user's downward pressure, prevent the housing unit 1 and the elastic buffer unit 4 from bearing all the downward pressure, and effectively improve the overall service life of the device , very durable, so it can indeed achieve the purpose of this new model.

However, the above are only examples of the present invention, which should not limit the scope of the present invention. Any simple equivalent changes and modifications made according to the scope of the patent application for this new model and the contents of the patent specification are still within the scope of the present invention. within the scope of this new patent.
