Abstract

The utility model belongs to the technical field of camera equipment, especially relates to handset cameras, and specifically refers to a handset camera head which can control the brightness and darkness of a handset screen. The handset camera head which can control the light switch-on and light switch-off of the handset screen comprises a camera body. The rear portion of the camera body is provided with a flexible circuit board. The flexible circuit board is provided with a first extension section which extends to one side. The front side of the first extension section is attached with a distance sensor in electric connection with a handset screen control circuit. The back side of the first extension section is attached with a PI reinforcing sheet. The external portion of the PI reinforcing sheet is attached with a double-sided tape in an adhesive mode. According to the utility model, the distance between the handset and the skin of a human body is sensed through the distance sensor, and the light switch-on and light switch-off of the handset screen are controlled in communication, so that electricity saving effects can be realized, and button pressing operations due to contact of an ear or the skin with the handset can be prevented, and problems of misoperation will not occur.

Description

A kind of mobile phone camera of controlling mobile phone screen light on and off

Technical field:

The utility model belongs to camera device technical field, relates in particular to mobile phone camera, refers in particular to a kind of mobile phone camera of controlling mobile phone screen light on and off.

Background technology:

At present, the touch screen type smart mobile phone of large-screen is more and more subject to user's favor, but, existing most of touch screen smart mobile phones under talking state, screen be substantially keep the state light or extinguish very short intermittence after light the long period again, like this, when when a lot of users make a phone call, ear is near mobile phone, ear or facial skin contact screen easily touch the key mapping on screen, cause misoperation, such as having hung up because of carelessness call etc., to user, bring some inconvenience.

Utility model content:

The purpose of this utility model is to overcome the above-mentioned weak point of existing product, and a kind of mobile phone camera of controlling mobile phone screen light on and off is provided.

The technical scheme that the utility model is realized its object employing is: a kind of mobile phone camera of controlling mobile phone screen light on and off, comprise camera body, camera rear body is provided with flexible circuit board, this flexible circuit board has first extension of extending to a side, front in the first extension has a range sensor being electrically connected to mobile phone screen control circuit, the back side in the first extension has PI reinforcing chip, and PI reinforcing chip outside is also pasted with two-sided tape.

Described flexible circuit board also has the second extension to downward-extension, in the front of the second extension end, with FR4 reinforcing chip, the back side, connector is installed.

The utility model is responded to the distance of mobile phone and human body skin by distance-sensor, when call, control extinguishing or lighting of mobile phone screen, both can play power saving effect, and can prevent again ear or skin contact mobile phone screen and produce button operation, the problem that does not just have misoperation produces.

Accompanying drawing explanation:

Fig. 1, Fig. 2, Fig. 3 are respectively front view, end view and the rearviews of the utility model mobile phone camera.

Embodiment:

Below in conjunction with specific embodiments and the drawings, the utility model is further illustrated.

As shown in FIG. 1 to 3, a kind of mobile phone camera of controlling mobile phone screen light on and off described in the utility model, comprise camera body 1, camera body 1 rear portion is provided with flexible circuit board 2, this flexible circuit board 2 has first extension 21 of extending to a side, front in the first extension 21 has a range sensor 3 being electrically connected to mobile phone screen control circuit, in the back side of the first extension 21 with PI reinforcing chip 4, and PI reinforcing chip 4(PI is polyimide resin based composite material) outside is also pasted with two-sided tape 5.

Described flexible circuit board 2 also has the second extension 22 to downward-extension, front in the second extension 22 ends is provided with connector 7 with FR4 reinforcing chip 6, the back side, to be connected with cell phone mainboard with mobile phone circuit, FR4 reinforcing chip 6(FR4 is glass mat) can strengthen the stable connection of the stable and connector 7 of the overall structure of camera.

In the utility model, range sensor 3 can be responded to earpiece place and (be generally mobile phone top, the position of camera is installed) with the distance of human body ear (or other barriers), when using mobile phone to receive calls, when the setpoint distance that is less than range sensor 3 when the distance of earpiece place and ear is for example less than 1cm, distance-sensor 3 can be sent induced signal to the control circuit of mobile phone screen, control mobile phone screen extinguishes, like this, both can play power saving effect, can prevent again ear or skin contact mobile phone screen and produce button operation, with regard to not having the problem of misoperation, produce, when having answered phone, mobile phone leaves ear distance enough greatly time, range sensor 3 provides induced signal again, controlling mobile phone screen lights automatically, therefore, the utility model can offer convenience to user.

To sum up, the utility model is responded to the distance of mobile phone and human body skin by distance-sensor, when call, control extinguishing or lighting of mobile phone screen, both can play power saving effect, can prevent again ear or skin contact mobile phone screen and produce button operation, with regard to not having the problem of misoperation, produce.
