Detailed Description

The present invention will be further described with reference to the following examples. The following description of the embodiments is merely provided to aid in understanding the invention. It should be noted that, for those skilled in the art, the present invention can be modified in several ways without departing from the principle of the present invention, and these modifications and modifications also fall into the protection scope of the claims of the present invention.

Example 1

As shown in fig. 1-7, the flip meter of the present embodiment includes a housing 1, and a flip 2 rotatably mounted on the housing and capable of reciprocating and linear movement between a first position and a second position relative to the housing 1. Specifically, the housing 1 and the flip cover 2 are mounted by the following structure: the improved structure of the flip-type portable electronic device is characterized in that a rotating shaft 6 is arranged on the shell 1, a rotating shaft sliding groove 7 which is matched with the flip 2 and has a waist-hole-shaped section is formed in the flip 2, and the rotating shaft 6 is inserted into the rotating shaft sliding groove, so that the flip 2 can perform reciprocating linear motion between a first position and a second position relative to the shell 1, and the flip 2 can rotate relative to the shell 1 no matter at the first position or at the second position.

At least one group of limiting blocks 3 are arranged on the shell 1 along the motion direction of the reciprocating linear motion, a limiting strip 4 is correspondingly arranged on the flip cover 2, and a gap 5 corresponding to the limiting block 3 is arranged on the limiting strip; flip 2 is under the closed condition, in during the primary importance, stopper 3 passes through breach 5 enters into directly over breach 5, in during the secondary importance, stopper 3 offsets with spacing 4, realizes flip 2 upset (pivoted) spacing. In this example, the two edges of the flip cover 2 perpendicular to the rotation axis are respectively provided with one of the limiting strips 4, and the positions of the limiting strips 4 near the two ends and the middle part are respectively provided with the notches 5 (i.e. each limiting strip is provided with three notches, one of which is located in the middle part of the limiting strip, and the other two notches are close to the two end parts of the limiting strip); the shell 1 is provided with the limiting block 3 at a position corresponding to the notch 5. By utilizing the mutual matching of the plurality of limiting blocks 3 and the limiting strips 4, when the flip cover 2 is closed and moves to the second position, stress points are uniformly distributed, the problem of middle warping and protrusion is avoided, and the risk of failure of functional parts (such as the cover opening detection key) is greatly reduced.

A pair of limiting bulges 8 which are oppositely arranged are formed in the rotating shaft sliding groove 7, so that the cross section of the rotating shaft sliding groove 7 is basically in an 8 shape. Under the combined action of the limiting protrusion 8 and the inner wall of the rotating shaft sliding groove 7, the rotating shaft 6 is limited to a certain extent no matter at the first position or the second position, and cannot move between the first position and the second position; also, applying a certain force to the flip 2 can make the rotating shaft 6 overcome the limiting effect of the limiting protrusion 8, so that the flip 2 moves between the first position and the second position, and the flip 2 can rotate relative to the housing 1 no matter at the first position or at the second position (provided that the flip 2 does not move from the first position to the second position in the closed state, i.e. the limiting block 3 does not abut against the limiting strip 4 to limit the rotation of the flip). The flip 2 is moved back and forth between the first position and the second position by substantially moving the shaft 6 within the shaft slot 7.

The working principle of the embodiment is as follows: the flip cover 2 is closed, and the limit block 3 enters the position right above the notch 5 through the notch 5 (at this time, the flip cover is located at the first position, as shown in fig. 6); then promote flip 2 to make it remove to the second position (as shown in fig. 7) from the primary importance, stopper 3 removes to spacing 4 tops to offset with spacing 4 (at this moment, stopper and corresponding breach stagger, and the lower surface of stopper offsets with the upper surface of spacing), realize flip 2 and overturn (rotate) spacing, promptly, flip 2 can't rotate for casing 1 under the interact of stopper 3 and spacing 4.

On the contrary, when the flip cover 2 is opened, the flip cover 2 is pushed to move from the second position to the first position (as shown in fig. 6), so that the limiting block 3 is separated from the limiting position of the limiting strip 4 and enters the position right above the notch 5; then the flip cover 2 is rotated, so that the limited block 3 is moved out of the gap 5.
