Detailed Description

Fig. 1 shows an embodiment of a handheld electronic device capable of providing protection when a user falls, which includes a body 1, a plurality of protection devices 2 and a sensor (not shown). The sensor is arranged in the body 1 and can correspondingly generate a control signal to be transmitted to each protection device 2 when the handheld electronic device falls down. The handheld electronic device may be a smart phone or a tablet computer, but not limited thereto. In this embodiment, the handheld electronic device is a smart phone, and the sensor is an acceleration sensor (G-sensor). When the acceleration sensor detects that the handheld electronic device is in a free-fall state, it indicates that a drop event has occurred, i.e., the handheld electronic device falls from the hand of the user. At this time, the acceleration sensor correspondingly generates a control signal to be transmitted to each protection device 2, so as to cause the protection devices 2 to enter the protection state shown in fig. 6 from the original state shown in fig. 1, and the detailed operation process thereof will be described later.

As shown in fig. 1, the main body 1 has a wide front surface 101 and a back surface 102 and a plurality of narrow side edges. The front side 101 has a screen 10. The plurality of sides include a right side 12, a left side 13, an upper side 14 and a lower side 15, and a corner 11 is formed at the connection point of every two adjacent sides. Each protection device 2 comprises a buffer 21. The plurality of buffering members 21 are respectively disposed at different corners 11 or different sides of the machine body 1. For example, when there are four protection devices 2, the buffer members 21 can be respectively disposed at the four corners 11 of the machine body 1, as shown in the figure, but can also be respectively disposed at the right side 12, the left side 13, the upper side 14 and the lower side 15 of the machine body 1. If there are three protection devices 2, the buffering members 21 can be respectively disposed at three of the corners 11 of the machine body 1, or respectively disposed at three of the sides of the machine body 1. If there are only two protection devices 2, the buffer members 21 can be respectively disposed at two oblique opposite corners 11 of the machine body 1, or respectively disposed at two opposite sides of the machine body 1. Even, only one protection device may be provided on the machine body 1. Although the plurality of protection devices 2 are not limited to the above, in order to achieve more comprehensive protection, the number of the plurality of protection devices 2 in one embodiment is preferably three or more.

The shape of the body 1 is not limited to the quadrangular shape shown in the drawings, and may be elliptical, circular, or another shape not having the corner 11, and in this case, the plurality of protectors 2 are provided on the side of the body 1.

Each buffer 21 is made of a plastic or rubber material having elasticity, but not limited thereto. As shown in fig. 1 to 3, each of the buffering members 21 has a front section 211 and a rear section 212 extending in different directions, in the preferred embodiment, since the buffering members 21 are respectively disposed at the corners 11 of the machine body 1, the front and

rear sections

211 and 212 of each buffering member 21 form an L-shaped piece so as to be respectively attached to two adjacent sides of the machine body 1 in the original state, for example, the front and

rear sections

211 and 212 of the buffering member 21 located at the upper right of fig. 1 are respectively attached to the upper side 14 and the right side 12 of the machine body 1. However, if the plurality of buffering members 21 are respectively disposed on each side of the machine body 1, the front and

rear sections

211 and 212 of each buffering member 21 can form a long flat piece so as to be attached to the same side of the machine body 1 in the original state.

Each buffer 21 can be driven to rotate by an angle, for example, 90 degrees, so that the front section 211 and the rear section 212 respectively protrude from the front surface 101 and the rear surface 102 of the machine body 1, as shown in fig. 6 and 7. In order to drive the plurality of buffering members 21, as shown in fig. 2 and 3, each protection device 2 further includes a driving portion 200, and the driving portions 200 are disposed in the machine body 1 and respectively connected to the buffering members 21, for driving the corresponding buffering members 21 to rotate when receiving the control signal. In this embodiment, as shown in fig. 2 and 3, each of the buffering members 21 further includes a spiral rod 202 fixedly connected between the front section 211 and the rear section 212 thereof, and the spiral rod 202 is twisted into a spiral shape and extends into the machine body 1 to be connected with the corresponding driving portion 200. Each driving portion 200 includes a housing 201 fixed in the machine body 1, a compression spring 203 arranged in the housing 201, and at least one fastening portion 22 capable of fastening the buffer 21. In this embodiment, two of the fastening portions 22 of each driving portion 200 are respectively fastened to the front and

rear sections

211 and 212 of the bumper 21 to form a double-sided fastening. However, in consideration of cost reduction and manufacturing and space utilization, the fastening portion 22 may have only one fastening portion 22 to form a single-side fastening, and in the case of a single fastening portion 22, the fastening portion 22 is not limited to be fastened to the buffer 21, for example, the fastening portion may be fastened to the screw 202 between the housing 201 and the buffer 21.

The top surface of the housing 201 has a long hole a through which the screw 202 is inserted. The long hole a has two opposite long sides respectively abutting against the spiral rod 202, so that the spiral shape of the spiral rod 202 and the guiding function of the long hole a can make the spiral rod 202 corresponding to a forward rotation angle or a reverse rotation angle when extending out or retracting through the long hole a, in this embodiment, the angle is 90 degrees. Preferably, the two opposite long sides of the long hole a are inwardly slightly arched to form an arc shape, so that the screw 202 can be smoothly extended or retracted.

The compression spring 203 is disposed in the housing 201 and located between the inner wall of the housing 201 and the end of the screw rod 202, so as to be compressed by the screw rod 202 to accumulate an elastic force when the screw rod 202 retracts into the housing 1 and to push the screw rod 202 to extend out of the housing 1 by the elastic force.

The buckling portion 22 is used for buckling the buffer member 21 and releasing the buffer member 21 only when receiving a control signal, so as to allow the screw rod 202 of the buffer member 21 to extend out of the housing 201. The buckle 22 may include a solenoid 220 and a tongue 221 that is driven by the solenoid 220 to extend or retract. The tongue piece 221 is inserted into the engaging groove 21a of the buffer 21 after protruding, thereby engaging with the buffer 21. Conversely, the tongue piece 221 is disengaged from the catch 21a after retraction. The solenoid valve 220 normally drives the tongue piece 221 to extend and snap into the slot 21a, and only drives the tongue piece 211 to retract and disengage from the slot 21a when a control signal is received. In addition, the fastening portion 22 may also include only the tongue piece 221, and the handheld electronic device itself is provided with one or more electromagnetic valves 220, and the electromagnetic valves 220 can drive the tongue piece 221 of each fastening portion 22 to extend or retract. To reduce cost and facilitate manufacturing and improve space utilization, in one implementation, the solenoid valve 220 may be positioned near the axis of the handheld electronic device.

When the protection device 2 is in the original state as shown in fig. 1 to 3, which indicates that the buffer member 21 is pressed by the user and abuts against the corner 11 (or the side edge) of the machine body 1, the compression spring 203 is compressed by the screw rod 202 due to the pressing force, and thus accumulates the elastic force, however, since the fastening piece 221 of the fastening portion 22 is fastened into the fastening slot 21a of the buffer member 21, the buffer member 21 cannot be ejected from the corner 11 (or the side edge) of the machine body 1 by the compression spring 203 due to being fastened. In short, the buffer 21 is now buckled.

Once the handheld electronic device falls and the control signal is transmitted to the solenoid valve 220, the solenoid valve 220 drives the buckle piece 221 to retract according to the control signal, thereby releasing the buffer 21. Once the buffer member 21 is released, the compression spring 203 will push the screw rod 202 to extend outward by the accumulated elastic force, so that the whole buffer member 21 extends outward for a distance and rotates forward 90 degrees, as shown in fig. 4 to 5. At this time, the protection device 2 has been brought into the protection state as shown in fig. 6 and 7 for the handheld electronic device. The buffer member 21 extends a distance from the corner 11 (or side) of the body 1, and the front and

rear sections

211 and 212 thereof respectively protrude from the front surface 101 and the rear surface 102 of the body 1, so that the handheld electronic device will not hit the ground when the handheld electronic device is grounded, thereby ensuring the safety of the handheld electronic device.

Then, the user only needs to press each buffer member 21 one by one to retract the screw 202 of each buffer member 21, and the front and

rear sections

211 and 212 of each buffer member 21 are also reversed by 90 degrees and lowered back to the original position synchronously with the retraction of the screw 202, so that each protection device 2 is restored to the original state from the protection state.

For the sake of aesthetic considerations, as shown in fig. 6, a groove 16 is further formed at the position of the machine body 1 corresponding to the plurality of buffering members 21 for respectively receiving the plurality of buffering members 21, so that the front sections 211 and the rear sections 212 of the plurality of buffering members 21 are just flush with the side of the machine body 1 in the original state. In order to prevent the buffer members 21 from being caught in the corresponding recesses 16 during rotation, in the above embodiment, the buffer members 21 are extended a little before rotation. However, if the front section 211 and the rear section 212 of the damper 21 are originally slightly higher than the corner 11 (or the side) and will not be caught during rotation, in this case, the damper 21 can rotate while being lifted or rotate at a direct angle without being lifted.

Compared with the existing mobile phone protection device, each protection device 2 of the invention only has two actions of stretching and rotating at most, so the required corresponding structure is relatively simple.

As described above, the handheld electronic device of the present invention not only can provide protection immediately when falling down by the protection device 2, but also can facilitate manufacturing and assembly by the simple structure of the protection device 2, so that the present invention has the advantage of low cost, and can sufficiently solve the problems of complex structure and high cost of the conventional mobile phone protection device.
