Description

Camera protection device

The present invention relates to a camera protection device, and more particularly to a camera protection device for a portable electronic device such as a mobile phone.

Portable electronic devices such as mobile phones and personal digital assistants (PDAs) are increasingly used, and portable electronic devices with cameras are more popular and concerned. The portable electronic device with camera has built-in camera for framing, focusing and controlling depth of field.

The portable electronic device with a camera usually has a camera protruding from the body of the portable electronic device. In order to prevent scratches caused by contact between the lens and the non-specific interference body, a convex surface is usually formed on the body to adhere a transparent plastic or glass. The transparent plastic or glass is located above the camera to prevent dust or moisture from coming into contact with the camera.

However, stamping and forming a convex surface on the body increases the thickness of the entire portable electronic device, which is disadvantageous to the lightness and thinness of the portable electronic device, and the convexity of the stamping and molding is not high.

In view of the above, it is necessary to provide a camera protection device capable of making the thickness of the portable electronic device thin.

A camera protection device is mounted on a body of a mobile phone to protect a camera module. The camera module is assembled on the body of the mobile phone, and the camera protection device has a protection. The mirror and a positioning component are located above the camera module, and the protection mirror is fixed on the positioning component, and the positioning component is fixed on the body.

Compared with the prior art, the camera protection device of the present invention covers the protection lens by a positioning member, and avoids directly forming a convex surface from the body to install the protection mirror, thereby saving assembly space. It is conducive to the light and thin mobile phone. In addition, the positioning member can also etch an annular sink by precise chemical etching technology, which greatly improves the assembly precision of the entire camera protection device.

Partial assembly drawing.

The invention discloses a camera protection device which is suitable for a portable electronic device such as a mobile phone. In the embodiment, a mobile phone is taken as an example for description.

Referring to FIG. 1 and FIG. 2, the camera protection device 20 of the present invention is mounted on a mobile phone 10 for protecting a camera module 12 from dust or moisture and the like to the camera module 12. The mobile phone 10 includes a body 11, a camera module 12, and a camera protection device 20. The camera protection device 20 includes a buffer block 13 , a positioning member 14 , a double-sided tape 15 and a protective mirror 16 .

A recess 111 is defined in the body 11 for mounting the camera module 12 therein. The body 11 has four positioning posts 112 protruding from the periphery of the groove 112. A circuit board (not shown) is further mounted in the body 11. The circuit board is electrically connected to the camera module 12 and connected to the signal.

The camera module 12 is a digital video input device that uses optical technology to acquire images. The sensor of the camera module 12 can be a charge coupled component (Charge Coupled Device, CCD) or Complementary Metal-Oxide Semiconductor (CMOS). The camera module 12 is substantially a block having a light incident surface 121.

The buffer block 13 is substantially an annular block, which may be a sponge or the like, for buffering the extrusion of the camera module 12 by other components, and filling the assembly gap of the entire camera protection device 10.

The positioning member 14 is substantially a rectangular sheet, and a circular through hole 141 is formed in the middle portion thereof for the light to pass through the through hole 141 to reach the camera module 12. The four corners of the positioning member 14 define four positioning holes 142 corresponding to the four positioning posts 112. The positioning member 14 is etched around the through hole 141 by a chemical etching technique to form an annular sinking groove 143. The shape and size of the sinker 143 are substantially equivalent to the shape and size of the protective mirror 16, and are used to limit the protective mirror 16. The positioning member 14 may be an iron piece or a copper piece or the like.

The shape and size of the double-sided tape 15 are substantially the same as the shape and size of the sinking groove 143 of the positioning member 14 for bonding the protective mirror 16 into the sinking groove 143.

The protective mirror 16 can be a transparent plastic or glass, which is located above the camera module 12 to prevent dust or moisture from contacting the camera module 12.

Referring to FIG. 3, when the camera protection device 10 is assembled, the camera module 12 is first installed in the recess 111 of the body 11 and electrically connected to the circuit board and connected to the signal; then the buffer block 13 is covered. The protective mask 16 is adhered to the sinking groove 143 of the positioning member 14 by the double-sided tape 15; finally, the positioning member 14 with the protective mirror 16 is covered in the groove. 111, at this time, the positioning hole 142 sets the position post 112 therein, and the positioning member 14 is integrated with the body 11 by thermal fusion technology, so that the protection mirror 16 seals the camera module 12, thereby effectively The camera module 12 is protected.

The camera protection device 10 of the present invention covers the protection lens 16 to the camera module 12 by means of a positioning member 14 , so as to avoid directly forming a convex surface from the body 11 to mount the protection mirror 16 , thereby saving The assembly space is conducive to the thin and light mobile phone. In addition, the positioning member 14 can also etch an annular sinking groove 143 by a precise chemical etching technique, thereby greatly improving the assembly precision of the entire camera protection device 10.

In summary, the present invention complies with the requirements of the invention patent and submits a patent application according to law. The above is only the preferred embodiment of the present invention, and the scope of the present invention is not limited to the above-described embodiments, and equivalent modifications or variations made by those skilled in the art in light of the spirit of the present invention are It should be covered by the following patent application.
