The following description of at least one exemplary embodiment is merely illustrative in nature and is in no way intended to limit the invention, its application, or uses. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts belong to the protection scope of the present invention.

The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. Words such as "upper," "lower," "left," "right," and the like, which indicate orientation or positional relationship, are used solely to facilitate description of the invention and to simplify description, and do not indicate or imply that the referenced devices/elements must have a particular orientation or be constructed and operated in a particular orientation, and therefore should not be construed as limiting the invention.

In the present invention, unless otherwise expressly specified or limited, the terms "mounted," "connected," "secured," and the like are to be construed broadly, e.g., as meaning fixedly connected, detachably connected, or integrally connected; may be directly connected or indirectly connected through an intermediate. The specific meaning of the above terms in the present invention can be understood according to specific situations by those skilled in the art.

It will be appreciated by those skilled in the art that features from the examples and embodiments described below may be combined with each other without conflict.

As shown in fig. 1 to 4, the inching switch structure of the conventional panel device includes a panel assembly 1, a lever 2, a bracket assembly 3, and a base assembly 4. Wherein base component 4 and panel component 1 are installed in bracket component 3, and base component 4 contains reset button 41, interior button 42, the inboard of panel component 1 articulates there is driving lever 2 that pushes away reset button 41 and push down when the panel component is pressed.

The shift lever 2 and the panel component 1 form a stroke amplifying mechanism. As shown in fig. 2, it uses the lever principle to realize the displacement amplification in the pressing process of the panel assembly 1 by changing the length or the included angle of two sides of the shift lever 2, and the switch can operate normally under a specific stroke.

The stroke enlarging mechanism shown in fig. 2 may encounter problems in practical use. Referring specifically to fig. 3 and 4, by pressing the panel assembly 1, the panel assembly 1 rotates downward and drives the shift lever 2 to move. The force applied by the external pressing is transmitted to the surface of the reset button 41 on the base component 4 through the panel component 1 and the shift lever 2, namely, the force application point a. Under the action of external force, the reset button 41 moves downwards for a certain distance to contact with the inner button 42, and at this time, a force action is generated between the reset button 41 and the inner button 42, and the action point is B (or C). Since the force applied to the reset button 41 by the shift lever 2 is not in the same straight line as the force applied to the reset button 41 by the inner button 42, the points of application of the forces are different, so that the reset button 41 rotates on the vertical plane. As shown in the stroke enlarging mechanism of fig. 2, ideally, the reset button 41 is not rotated on a vertical plane by an external force. In actual movement, as shown in fig. 3 and 4, the position of the action point a changes along with the position of the switch on-off switching action point, so that when the panel assembly 1 is pressed, the stroke amplification effect is weakened, the hand feeling of the switch press is affected, and the switch may fail in a more serious case.

As shown in fig. 5 and 6, the panel device for improving the amplification efficiency of the inching switch stroke according to the embodiment of the present invention is different from the prior art in that two shift levers 2 are provided and are symmetrically distributed on both sides of the middle line of the reset button 41. Because the left side and the right side of the reset key 41 are respectively provided with the deflector rod 2 to form the double-warped rod type stroke amplification mechanism, when external force is applied, the reset key 41 is in an approximate force balance state and cannot rotate on a vertical plane, thereby improving the switch stroke amplification efficiency and reducing the probability of switch failure.

As an implementation mode, the driving lever 2 comprises a first rod section 22 and a second rod section 21 which are connected in an obtuse angle, a protruding point which acts with a reset key is arranged at the head of the first rod section 22, and pin shafts are arranged on two sides of the connecting position of the first rod section and the second rod section and matched with the pin holes in the panel component 1.

Specifically, the base component 4 is provided with a mounting groove for mounting the reset key 41, and a reset spring 43 is arranged between the reset key 41 and the bottom wall of the mounting groove. The base component 4 is provided with a contact piece 45, the lower part of the inner key penetrates out of the bottom of the mounting groove and is connected with a shifting fork block 44, the shifting fork block is provided with a V-shaped fork groove, the fork groove fork is arranged on the contact piece, and the contact piece 45 is communicated with or separated from the contact by shifting the shifting fork block when the reset key is pressed down or reset upwards. The base component 4 and the support component 3 are buckled by a buckle.

In addition to the above preferred embodiments, the present invention has other embodiments, and those skilled in the art can make various changes and modifications according to the present invention without departing from the spirit of the present invention, which should fall within the scope defined by the appended claims.
