Abstract

The utility model relates to a cell-phone protection device comprises four baffles and a backplate, and there is controlling means at the backplate center, and the inside stretches out four push rods and passes the backplate and link to each other with four baffles, has rotatable cam to be used for promoting four connecting rods in the controlling means. When the mobile phone is used, the mobile phone is placed in the sponge inner lining, and when the mobile phone falls, the cam rotates to push the four push rods to push the baffle plate to release the sponge, so that the mobile phone inside can be protected.

Description

Mobile phone protection device

Technical Field

The utility model relates to a protection device that the cell-phone was prevented falling, specific utilize gravity sensor to prevent falling cell-phone protection device of cell-phone automatically that says so.

Background

When the mobile phone falls to the ground from a higher position, the mobile phone is easy to break, and in order to prevent the mobile phone from breaking after falling from the higher position, an anti-falling device must be installed on the mobile phone.

Disclosure of Invention

An object of the utility model is to provide a cell-phone protection device, can all-round protection cell-phone fall down the fall down and break, especially present protection device can't protect the cell-phone screen all to touch the broken condition of screen behind the edges and corners, and the sponge can all-round parcel live the cell-phone and prevent the damage of special case to the cell-phone, because the sponge provides great buoyancy after the cell-phone falls into the aquatic, can not sink into the aquatic in the cell-phone short time, can make things convenient for us to drag for the cell-phone. And the sponge is light and easy to compress and recover fast characteristics cell-phone protection device can cyclic utilization, and the sponge is also very cheap, more economic.

The utility model adopts the technical scheme that: the baffle and the light and thin hard mobile phone protection device tightly compress the sponge, the baffle is in contact with the cam through the push rods, each push rod is provided with a return spring, and the middle of the cam is embedded with an integrated circuit board, a battery, a motor and a circular driving device. Three supports are arranged on the back plate.

The utility model discloses an above-mentioned technical scheme: because the baffle and the light and thin cell-phone protection device of stereoplasm closely compress the sponge, the baffle passes through the push rod and contacts with the cam. Each push rod is also provided with a return spring. After the mobile phone protection device is installed, a mobile phone can be protected in all directions, so that the problems that a mobile phone screen is broken when falling down, especially the current protection device cannot protect the mobile phone screen from being broken due to edges and corners and the like are solved, and the mobile phone protection device is very convenient to install and use.

Drawings

The present invention will be described in detail with reference to the accompanying drawings and examples.

FIG. 1 is an overall appearance view;

fig. 2 is an enlarged view of a portion of the detail.

In the figure: 1. an upper baffle plate and a lower baffle plate; 2. A sponge; 3. a back plate; 4. an integrated circuit board; 5. a cam; 6. a push rod; 7. a left baffle and a right baffle; 8. a motor; 9. a battery; 10. a return spring; 11. a circular drive device; 12. and (4) a support column.

Detailed Description

FIG. 1 shows: wrap up at the cell-phone periphery with cell-phone protection device's form, by baffle 1 about, baffle 7 and a backplate 3 are constituteed, 3 embedded sponge 2 of backplate, 3 central inlays a circular drive arrangement 11 of backplate, there is cam 5 in the circular drive arrangement 11, motor 8, battery 9, integrated circuit board 4, cam 5 is fixed and is contacted at the center of circular drive arrangement 11 and the one end of four push rods 6, baffle 1 about and baffle 7 about the push rod 6 other end is connected respectively, reset spring 10 is fixed at push rod 6, the other end is fixed in circular drive arrangement 11, there are three support columns 12 in the circular drive arrangement 11.

When the mobile phone provided with the mobile phone protection device falls, the sensor in the integrated circuit board 4 senses acceleration change and the integrated circuit board 4 analyzes the falling state, when the speed and time of the object motion reach the maximum values specified by the processor in the integrated circuit board 4, the motor 8 drives the cam 5 to rotate and push out the four push rods 6 after the integrated circuit board 4 analyzes information, the upper baffle plate 1, the lower baffle plate 1, the left baffle plate 7 and the right baffle plate 7 release the sponge 2, and the sponge 2 expands to wrap the mobile phone. The left baffle 7, the right baffle 7, the upper baffle 1, the lower baffle 1 and the back plate 3 are adhered with sponge 2.

When not using, reset spring 10 provides elasticity and acts on push rod 6, and push rod 6 provides pulling force and acts on baffle 1 about with baffle 7 about, and baffle 1 about and baffle 7 provide pressure and act on sponge 2 about, and sponge 2 is closely compressed between the frivolous cell-phone protection device of stereoplasm and baffle 1 about and baffle 7 about with sponge 2 to compress sponge 2 to 3mm by 3 cm.

When the mobile phone protection device is used, a mobile phone is arranged in the hard light and thin mobile phone protection device, the reset spring 10 provides elastic force to act on the push rod 6, the push rod 6 provides tensile force to act on the upper baffle plate 1, the lower baffle plate 1, the left baffle plate 7 and the right baffle plate 7, pressure is provided by the upper baffle plate 1, the lower baffle plate 1, the left baffle plate 7 and the right baffle plate 7 to act on the sponge 2, and the sponge 2 is tightly compressed between the hard light and thin mobile phone protection device and the upper baffle plate 1, the lower baffle.

After the mobile phone falls, a sensor in the integrated circuit board 4 measures the gravity acceleration, calculates the speed of the mobile phone in the vertical direction and judges the falling state of the mobile phone, the integrated circuit board 4 analyzes information to determine that the mobile phone falls and then controls the cam 5 to rotate, the push rod 6 is pushed away from the initial position along with the rotation, the left baffle 7, the right baffle 7, the upper baffle 1 and the lower baffle 1 of the anti-falling mobile phone protection device are pushed out, the sponge 2 is not limited by the pressure of the left baffle 7, the right baffle 7, the upper baffle 1 and the lower baffle 1, the sponge 2 expands along with the expansion, the expanded sponge 2 wraps the mobile phone, the sponge 2 plays a buffering role, and the damage to.
