Background
The pressing mechanism generally comprises a fixed seat and a pressing piece movably arranged on the fixed seat, and the pressing piece can move relative to the fixed seat by applying certain pressure to the pressing piece so as to realize a specific function. The application range of the pressing mechanism is very wide, for example, a pressing type switch button, a keyboard, a floor drain, and the like. For a pressing piece with smaller stress area, the stress is concentrated during pressing, the generated moment is smaller, and the balanced pressing of the pressing mechanism can be ensured; however, if the stress area of the pressing piece is large, side-offset pressing is often generated, and the generated moment is large, so that the pressing piece is easy to incline or even be blocked in the moving process. In order to ensure that the conventional pressing mechanism still can work normally under the action of a large moment, the length of a matched shaft in the pressing direction is generally increased (for example, a linear bearing is additionally arranged), so that the length of a product is oversized, and the production cost is increased.

The drawings illustrate preferred embodiments of the invention. This invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete.
It will be understood that when an element is referred to as being "fixed to" another element, it can be directly on the other element or intervening elements may also be present. When an element is referred to as being "connected" to another element, it can be directly connected to the other element or intervening elements may also be present. In contrast, when an element is referred to as being "directly on" another element, there are no intervening elements present. The terms "vertical," "horizontal," and the like are used herein for illustrative purposes only. The terms "first," "second," "third," and "fourth" in this disclosure do not denote a particular quantity or order, but rather are used for distinguishing between similar or identical items.
Referring to fig. 1 to 12, a pressing balance mechanism includes a fixing base 10, a pressing member 20 and a balance ring 30. Wherein, the pressing piece 20 is movably sleeved with the fixed seat 10, and the pressing piece 20 can axially move relative to the fixed seat 10; the balance ring 30 is rotatably connected between the fixing base 10 and the pressing piece 20, and a plurality of contacts are uniformly arranged in the circumferential direction of the balance ring 30, when the pressing piece 20 is pressed by an external force, the balance ring 30 rotates around an axis extending along the axial direction, and the plurality of contacts respectively act on the pressing piece 20, so that the same axial force is generated on the periphery of the pressing piece 20.

The fixing base 10 and the pressing piece 20 are movably sleeved into a whole, specifically, the pressing piece 20 can be sleeved on the periphery of the fixing base 10, or the pressing piece 20 can be sleeved in the fixing base 10. The pressing piece 20 can move along the axial direction relative to the fixing seat 10 under the action of external force, and the axial direction refers to the direction perpendicular to the pressing plane of the pressing piece 20. When the pressing piece 20 receives the pressing force, axial displacement is generated, the balance ring 30 is driven to rotate, and the balance ring 30 can react with the pressing piece 20 through the contact while rotating, so that the periphery of the pressing piece 20 can generate axial force with the same magnitude and direction, and the pressing piece 20 is always in a balanced state in the moving process and cannot deflect towards one side.

Thus, when the pressing piece 20 is pressed at the edge, the moment is larger, and the moment can be decomposed and counteracted due to the action of the contacts of the balance ring 30, and only the axial force coaxial with the movement direction is remained, so that the pressing piece 20 can move stably along the axial direction without generating the phenomenon of inclination or clamping, and the movement of the pressing piece 20 is smoother; and the matched shaft length of the pressing piece 20 is not required to be increased, so that the material consumption can be saved, and the cost can be reduced.
