Shell structure of portable intelligent terminal

Technical Field

The utility model relates to the technical field of micro electronics, in particular to a shell structure of a portable intelligent terminal.

Background

Along with the popularization of electronization and intellectualization of office and family life, the shell structure of a portable intelligent terminal is gradually known by people, and the portable intelligent terminal is generally applied to the control of lifting of an electric office table, and intelligent control terminals of household appliances such as an air conditioner, a sound box, a television, a humidifier and the like in an office or a family, and is generally a shell structure or a box body placed on a table top, namely an intelligent terminal shell structure, an information terminal shell structure, a portable workstation shell structure or a miniature electronic equipment shell structure.

The shell structure of the portable intelligent terminal has the obvious characteristic that the portable intelligent terminal has a flip structure, and the flip is folded with the shell when the portable intelligent terminal is carried; when placing the mesa like the desktop, flip opens certain angle around the pin joint, supports shell structure or called box body, and the panel is facing to the people like the display screen face to convenient operation uses.

But the shell structure of the portable intelligent terminal of the prior art above has an obvious not enough, involves under the not enough condition of design space, and the pin joint adopts conventional round pin axle construction, can influence the outward appearance of product, or does corresponding sacrifice in the volume and realize the flip function, so under the circumstances that can not give way in the outward appearance, the flip structure that can use just receives the limitation very much. In other words, under the condition of normal cover turning, no space is used for making the pin shaft, and when the appearance requirement is higher, no pin shaft scheme can be adopted. In short, the shell structure of the portable intelligent terminal in the prior art is difficult to realize both the flexibility and reliability of the hinge pin of the flip structure and the appearance of the product, and is harmonious and uniform. Improvements are needed.

SUMMERY OF THE UTILITY MODEL

The utility model aims to solve the technical problem of providing a shell structure of a portable intelligent terminal, which is flexible and reliable for a pin shaft connecting a flip cover and a rear shell and does not influence the appearance of the product.

The technical scheme of the utility model is that a shell structure of a portable intelligent terminal is provided, which comprises a shell structure body, wherein a rear shell in the shell structure body comprises a flip cover and an upper rear shell; the inner top side of the flip cover is rotationally connected with the upper rear shell through a pin shaft and a shaft sleeve, at least one shaft sleeve is fixed at the lower end of a sliding block, the sliding block is vertically and slidably matched in at least one vertical sliding groove fixedly connected with the inner wall of the upper rear shell, and a spring for enabling the sliding block to upwards reset is arranged on the sliding block and the vertical sliding groove; the top side of the flip cover is provided with a notch for avoiding interfering the lower end of the sliding block.

After the structure is adopted, the shell structure of the portable intelligent terminal has the following advantages: because the pin roll of connecting flip and back casing is in shell structure or called box body inboard, only sees one or two in the outward appearance for avoiding interfering the breach of slider lower extreme, especially the design of slider, when flip need be opened, overcomes the spring resistance, draws flip downwards earlier in order to prevent to interfere other parts of back casing, opens to the support angle again. Even if the design space is insufficient, the pin shaft can still be flexible and reliable, and the appearance of the product is not influenced and not influenced. And the volume does not need to be correspondingly sacrificed to realize the flip function, namely, the volume does not need to be increased for realizing the flip function. The hinge pin connecting structure of the flip cover and the rear shell is flexible and reliable under the condition that the appearance and the volume are not compromised.
