Detailed Description

The following are specific embodiments of the present invention and the accompanying drawings are used to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

As shown in fig. 1-7, a toggle switch includes: the key comprises a base 100, a key 200, a sliding block 300 and an elastic element 400, wherein the base 100 is provided with a sliding groove surface 110; the key 200 is rotatably connected with the base 100, and the key 200 is provided with a sliding groove 210; the slider 300 is movably mounted on the sliding groove 210, and the slider 300 can rotate with the key 200, and the bottom end of the slider 300 is slidably contacted with the sliding groove surface 110; two ends of the elastic member 400 are respectively connected with the sliding block 300 and the key 200 in an abutting manner, and the elastic member 400 exerts an elastic force on the key 200 when being compressed; when the key 200 is pressed, the bottom end of the slider 300 slides on the sliding groove surface 110, the surface shape of the sliding groove surface 110 can make the slider 300 displace relative to the key 200 along the depth direction of the sliding groove 210, and the displacement of the slider 300 drives the compression amount of the elastic member 400 to change.

The elastic member 400 is preferably a spring, the key 200 can rotate when being pressed (i.e. the key 200 is configured to be in a toggle structure), since the sliding block 300 is installed in the sliding groove 210, the sliding block 300 can rotate together when the key 200 rotates, and the sliding block 300 can also move along the sliding groove 210 relative to the key 200 because the sliding block 300 is connected with the key 200; the bottom end of the slider 300 is in contact with the sliding groove surface 110 by the elastic force of the elastic member 400, and the bottom end of the slider 300 slides along the sliding groove surface 110 when the slider 300 rotates together with the key 200.

It is important to note that the sliding groove surface 110 is configured to enable the sliding block 300 to displace along the sliding groove 210, that is, the sliding track of the bottom end of the sliding block 300 along the sliding groove surface 110 does not completely coincide with the arc line configured by taking the rotation center as the center of the circle, so that the bottom end of the sliding block 300 extends or is pushed back by the elastic force of the elastic element 400 when sliding on the sliding groove surface 110.

In this embodiment, the key force and the key feel of the key 200 are divided into two parts and designed separately, the key force is controlled by the compression amount of the elastic member 400, that is, the elastic force applied to the key 200 by the elastic member 400 is the key force, and the compression amount of the elastic member 400 is affected by the displacement of the sliding block 300, the displacement of the sliding block 300 is related to the stroke of the sliding block 300 on the chute surface 110, and the stroke of the sliding block 300 on the chute surface 110 is related to the rotation angle of the key 200, so the rotation angle of the key 200 corresponds to the magnitude of the key force; the hand feeling of the key is controlled by the sliding track of the bottom end of the sliding block 300 on the sliding groove surface 110.

In short, when the key 200 is pressed, the key rotates, the shape of the sliding groove surface 110 is specially designed, and as the bottom end of the sliding block 300 slides on the sliding groove surface 110, the sliding block 300 generates displacement change in the sliding groove 210, and the displacement change affects the compression amount of the elastic element 400, so as to generate the change of the key force and the key hand feeling.

The elastic force of the elastic member 400 is calculated as: the elastic force F = elastic coefficient compression amount, when the sliding track of the sliding block 300 is fixed, the size of the key force can be finely adjusted only by adjusting the height dimension of the elastic member 400; if the variation of the key pressing force is large, the wire diameter of the elastic member 400 can be adjusted, so that the elastic coefficient of the elastic member 400 can be changed; when the parameters of the elastic element 400 are fixed, the hand feeling of the key is adjusted, and only the shape of the sliding groove surface 110 (i.e. the sliding track of the sliding block 300) needs to be adjusted, and the relationship between the rotation angle and the sliding stroke of the key 200 can be accurately calculated according to the graph of the sliding track line; the scheme has wider adjustment range and simple adjustment items, and can reduce the period of adjusting the hand feeling of the keys.

The cost of the elastic element 400 and the sliding block 300 added in the scheme is lower, and the number of parts of the balancing rod is reduced compared with the existing scheme, so that the whole switch cost is still lower, and the internal structure of the whole switch is simplified and more compact.

After the key 200 is pressed, the sliding block 300 rotates relative to the base 100 and rotates together, the bottom end of the sliding block 300 moves along the sliding groove surface 110 when the sliding block 300 rotates, so that the hand feeling of the key 200 is controlled through the track of the sliding groove surface 110, the displacement of the sliding block 300 in the sliding groove 210 is controlled through the shape of the sliding groove surface 110, and then the elastic force applied to the key 200 by the elastic piece 400 is controlled, so that the driving sense is greatly improved, the design and development are facilitated, and the design and development cost is reduced.

In the above embodiment, the key 200 is configured such that the rotation angle of the key 200 increases when the key 200 is pressed, and the sliding stroke of the slider 300 on the sliding groove surface 110 is positively correlated with the rotation angle of the key 200; that is, the slide stroke of the slider 300 is increased as the rotation angle of the key 200 is increased, and the bottom of the slider 300 can slide on the sliding groove surface 110 as the key 200 rotates.

The elastic member 400 is configured such that the compression amount of the elastic member 400 increases and the elastic force applied to the key 200 increases when the sliding block 300 is displaced in a direction approaching the key 200, and the compression amount of the elastic member 400 decreases and the elastic force applied to the key 200 decreases when the sliding block 300 is displaced in a direction away from the key 200; the slider 300 can move towards the key 200 or away from the key 200, thereby controlling the elastic force applied to the key 200 by the elastic member 400.

When the sliding block 300 is displaced, the distance between the sliding block 300 and the key 200 is changed, and the compression amount of the elastic element 400 is inversely related to the distance value between the sliding block 300 and the key 200; since the elastic member 400 is located between the sliding block 300 and the key 200, the essence of changing the magnitude of the key force is to change the distance between the sliding block 300 and the key 200, the larger the distance, the smaller the compression amount of the elastic member 400, and the smaller the distance, the larger the compression amount of the elastic member 400.

As shown in fig. 2, 3, 4 and 6, the toggle switch further includes a push rod 500, the push rod 500 is movably mounted on the base 100, and the push rod 500 is linked with the button 200, and when the button 200 is pressed, the push rod 500 is pushed to be pressed down.

Preferably, the base 100 is internally provided with a conductive rubber 130 and a circuit board 140, the push rod 500, the conductive rubber 130 and the circuit board 140 are sequentially arranged from top to bottom, the circuit board 140 is provided with at least one conductive contact 150, the push rod 500 is aligned with the conductive contact 150, and when the push rod 500 is pressed down, the conductive rubber 130 is pushed to deform and touch the conductive contact 150 on the circuit board 140.

The key 200 triggers the conductive contact 150 on the circuit board 140 through the push rod 500 and the conductive rubber 130, wherein the base 100 is provided with a guide slot along the downward pressing direction of the push rod 500, the push rod 500 can move along the guide slot and press downward, and when the push rod 500 presses downward, the conductive rubber 130 is pressed, and the conductive contact 150 is triggered through the conductive rubber 130.

As shown in fig. 2, 5 and 7, the sliding block 300 is provided with a mounting groove 310, and the elastic member 400 is mounted in the mounting groove 310. The installation of the sliding block 300 in the installation groove 310 can prevent the elastic member 400 from moving or deforming in the radial direction, and can maintain the elastic member 400.

As shown in fig. 2, 3, 5 and 7, the bottom end of the sliding block 300 has a rotatable rolling wheel 320, and the rolling wheel 320 is in contact with the sliding groove surface 110. The bottom end of the sliding block 300 is in contact with the sliding groove surface 110 through the rolling wheel 320, so that a rolling connection effect can be formed between the bottom end of the sliding block 300 and the sliding groove surface 110, and the sliding block 300 can better slide on the sliding groove surface 110.

Preferably, the sliding groove surface 110 is configured as an arc structure, and the sliding groove surface 110 has at least one arc protrusion 120 thereon for pushing the sliding block 300. In the actual operation process, the bottom of the sliding block 300 is in the process of passing through the cambered surface convex part 120, the sliding block 300 is reversely pushed below, and then stretches out again under the action of the elastic element 400, namely the key force is suddenly increased after the key 200 is shifted in place, so that better key hand feeling can be obtained.
