Detailed Description

The present invention will now be further described with reference to the accompanying drawings.

Referring to fig. 1, fig. 1 shows an embodiment of the present invention, which is an openable and closable waterproof structure of a mobile phone battery cover. The problem that this embodiment will be solved is that detachable battery cover 1 mostly will use screw 6 among the current three proofings cell-phone, causes often because there is not the instrument to lead to in time changing the battery in the use.

In the embodiment, the outer surface direction of the battery cover 1 is the front surface and the outer part, and the inner surface direction is the back surface and the inner part; and the direction moving along the radial direction of the rotating shaft is taken as the Z direction; the above settings are for better illustration only and should not be considered as limitations of the present invention.

Referring to fig. 1 to 3, the present embodiment includes a rear case 4 disposed inside a battery cover 1, and a circular through hole is formed in the center of the rear case 4, through which a rotation shaft passes and connects a knob 2 and a gasket 5 disposed on both sides of the front and back of the rear case 4. A sealing ring 3 is arranged between the back surface of the knob 2 and the front surface of the rear shell. The sealing ring 3 can be used for water sealing of mobile phone equipment inside the through hole, and the ring body of the sealing ring 3 is distributed around the through hole in a closed manner; the seal ring 3 and the through hole are preferably circular. Further, the sealing ring 3 is arranged in a circular groove on the front surface of the rear shell 4. In addition, the shapes of the battery cover 1 and the rear case 4 are not limited to the picture style.

Referring to fig. 4, the back surface of the rear shell 4 is provided with three protrusions, preferably three sections of slope protrusions 7, the slope protrusions 7 are uniformly arranged along the circumference and are arc-shaped, and the highest point is arranged on the slope protrusions 7. Referring to fig. 5, the front surface of the gasket 5 is provided with three corresponding sunken parts and slope structures, and the sunken parts and the slopes are integrally arranged into three corresponding slope grooves 8; the lowest point of the slope groove 8 is a sunken part for placing the corresponding highest point; the arc slope is a slope (track) for the protrusion to slide out and separate from the lowest point. The number of the convex portions and the depressed portions can be set as required, and the preferred three positions of the present embodiment are not intended as limitations of the present invention.

Referring to fig. 2, initially, the knob 2 is in an open state; the bulge (highest point) of the rear shell 4 is completely placed in the depression (lowest point) of the gasket 5, at which time the sealing ring 3 is not pressed and therefore not watertight. Referring to fig. 3, when the knob 2 is rotated, the coaxial washers 5 rotate synchronously, and the fixed bosses are disengaged and slide relatively to the front face of the washers 5 along the circumferential slope and abut against the front face. In the movement process, the distance between the back surface of the fixedly arranged rear shell 4 and the front surface of the movable gasket 5 is increased, so that the knob 2 is dragged to move backwards along the Z direction, and the back surface of the knob 2 extrudes and compresses the sealing ring 3 to realize water sealing.

Preferably, referring to fig. 7, the front surface of the knob 2 is provided with a concave straight groove; the size of the straight groove is preferably matched with the size of a fingernail and a coin, so that the battery cover 1 can be opened and closed by rotating the straight groove by 90 degrees by hands or the coin, and the battery cover 1 can be conveniently detached.

Preferably, the rotating shaft between the knob 2 and the washer 4 further comprises a screw 6, and the screw 6 passes through a shaft hole in the center of the washer 4 and is fixedly connected with a threaded hole in the back end face of the rotating shaft. Referring to fig. 5 and 6, the front surface of the washer 4 is further provided with four hole locations 10, the back end surface of the rotating shaft is provided with four corresponding positioning columns 9, and the positioning columns 9 are inserted into the holes to realize fixation. The positioning column 9 with a similar bolt structure not only enhances the connection strength, but also is beneficial to the synchronous and coaxial rotation of the driving washer 4, and can ensure that the gasket 5 moves along with the rotation process of the knob 2.

Referring to fig. 1, 6 to 7, the present embodiment further includes a locking mechanism, and the battery cover 1 is provided with a through knob opening for the knob 2 to be disposed. The back of the battery cover 1 is provided with a battery cover blocking rib 11, and the side wall of the knob is provided with a knob blocking rib 12; when the knob 2 is opened, the battery cover rib 11 and the knob rib 12 are in a staggered relationship, and the battery cover 1 can be taken out. When the knob 2 is closed, the knob rib 12 is screwed into the limiting groove on the inner wall of the battery cover rib 11 to complete the locking of the battery cover 1.

Furthermore, two knob stop ribs 12 are arranged oppositely along the circumference of the knob 2; the battery cover stop rib 11 is arranged at one position and is arranged at the lower side of the inner wall of the knob opening. The sizes of the battery cover rib and the knob rib are adjusted according to requirements, and two gears of 0 degree and 90 degrees can be preferably arranged between the battery cover rib 11 and the knob rib 12 so as to correspond to two states of locking and unlocking. In the rotating process, the knob 2 moves forwards and backwards along the Z direction by the aid of the slope matched with the rotary motion of the knob 2, and the sealing ring 3 is matched to realize sealing and water proofing.

In the waterproof knob device adopted in the embodiment, the battery cover 1 can be opened only by using common coins or finger nails to rotate a certain angle when the battery cover 1 is opened. Sealing washer 3 and slope structure can be fine again guarantee the waterproof performance of three proofings machine.

The embodiments of the present invention have been described in conjunction with the accompanying drawings and examples, the structures of which are not intended to limit the present invention, and those skilled in the art can make modifications as required, and all changes and modifications within the scope of the appended claims are within the scope of protection.
