Background technique

At present, slide-type mobile communication terminals, such as slide mobile phones, are mainly semi-automatic slide-type structures, and the structure of the sliding pivot assembly is basically composed of a slide cover, a base plate, and an elastic element connecting the slide cover and the base plate. . The first half of the sliding stroke relies on external force to push the sliding cover to slide, and at the same time compresses the elastic element to make the elastic element accumulate elasticity. However, the cooperation between the sliding cover and the bottom plate is usually the cooperation between metal and plastic parts with self-sliding characteristics, so there is basically no friction. Due to the large elasticity of the elastic element, the sliding cover slides at an accelerated rate relative to the bottom plate. When the sliding cover slides When it comes to both ends, it has a lot of impact. The high impact force will act on the movable parts of the slide-type electronic equipment, such as flexible circuits, etc., causing damage to the electronic equipment and shortening the service life of the electronic equipment.

In the prior art, in order to reduce the damage of such impact force to electronic equipment, an emergency stop buffer limit device is provided at the terminal position of the sliding stroke. The most commonly used limit device is a rubber pad, although a soft rubber pad can Absorb part of the impact, but due to the fast running speed of the slider, it needs to stop suddenly on the rubber pad, so it will still cause a lot of impact to the electronic equipment.

In the prior art, there is also a buffer mechanism composed of a socket rod, a first spring, an inner rod, a shaft connector, a second spring and an adjustment member, but the buffer mechanism has a complex structure and takes up a large space, which is not suitable for The thinning development trend of today's slider mobile phone.
