It should be noted that: like reference numbers and letters refer to like items in the following figures, and thus, once an item is defined in one figure, further discussion thereof is not required in subsequent figures.
As shown in fig. 1 to 8, the present embodiment provides a device for buffering an impact force, which can be applied to electronic devices such as a mobile phone and a tablet computer to prevent the electronic devices from being damaged due to falling, impact, etc., so as to better protect the electronic devices.
Specifically, the device for buffering the impact force includes a body 100. For example, the body 100 may be a housing of an electronic device.
More specifically, the device for buffering the impact force further comprises a first electromagnet 11, a second electromagnet 12, an elastic member 200 and a control module 400. Wherein, the first electromagnet 11 and the second electromagnet 12 are movably disposed on the body 100. That is, the first electromagnet 11 and the second electromagnet 12 can move in opposite directions under the action of external force, and the external force can be repulsive force provided by other magnets and repulsive force provided by other electromagnets; the driving force provided by other driving devices can also be provided, and the application is not limited to this.
In the present application, the elastic member 200 is located outside the body 100, one end of the elastic member 200 is fixed to the first electromagnet 11, and the other end is fixed to the second electromagnet 12, and when the first electromagnet 11 and the second electromagnet 12 move towards each other, the elastic member 200 forms an elastic bulge 500 outside the body 100. The control module 400 is electrically connected to the gravity sensor 300 of the electronic device, and is configured to control the first electromagnet 11 and the second electromagnet 12 to move towards each other according to a gravity variation value detected by the gravity sensor 300, so that the elastic member 200 forms the bulge 500. The gravity sensor 300 may utilize an original gravity sensor of the electronic device, or may provide a gravity sensor for detecting a gravity change for buffering an impact force, which is not limited in the present application.
For example, when the gravity sensor 300 detects that the gravity change value of the device is large, that is, the device is in acceleration motion, it can be preliminarily determined that the device falls or is in unexpected acceleration movement, that is, there is a risk of collision. The control module 400 controls the first electromagnet 11 and the second electromagnet 12 to move towards each other according to the gravity change value detected by the gravity sensor 300, and at this time, the elastic member 200 forms a bulge 500, so that the device can provide enough elasticity when an impact occurs, thereby better protecting the device.
Therefore, by movably disposing both the first electromagnet 11 and the second electromagnet 12 on the body 100, one end of the elastic member 200 is fixed to the first electromagnet 11 and the other end is fixed to the second electromagnet 12. The gravity sensor 300 detects a gravity variation value of the apparatus, and the control module 400 is electrically connected to the gravity sensor 300, and is configured to control a formation state of the bulge 500 according to the gravity variation value detected by the gravity sensor 300.
For example, when the device falls, the control module 400 controls the first electromagnet 11 and the second electromagnet 12 to move towards each other, so that the elastic member 200 forms the bulge 500, and thus when the device hits the ground, the bulge 500 can contact with the ground in advance, and because the bulge 500 has elasticity, the impact force of the device hitting the ground can be buffered well, the device is effectively prevented from falling and being damaged, and the device is protected well.
Similarly, the impact force buffering device can effectively buffer impact force for other impact states, well protect the device and prolong the service life of the device.
Alternatively, the first electromagnet 11 is located at the first side 21 of the body 100, the second electromagnet 12 is located at the second side 22 of the body 100, a corner of the body 100 is formed between the first side 21 and the second side 22, and the elastic member 200 forms a bulge 500 at the corner.
Since the corners of the device are more easily damaged by the impact force during the impact, the bulge 500 can better cushion the impact force and protect the device.
It should be noted that, the position of the bulge 500 may be set according to the specific structure of the device, for example, the bulge 500 may be set at a corner, a side edge, a tip, etc. of the device, which are subjected to a small stress, so as to well prevent the device from being damaged by impact and protect the device.
Alternatively, the first electromagnet 11 and the second electromagnet 12 are respectively located at both ends of one side edge of the body 100, and the elastic member 200 forms a bulge 500 at the middle of the side edge.
In the above embodiment, the bulge 500 can better absorb the impact force applied to the side of the device when the impact occurs, and can better protect the side of the device.
Optionally, the body 100 is provided with a first limiting groove 31, and the first electromagnet 11 is disposed in the first limiting groove 31 and can move along the extending direction of the first limiting groove 31.
The body 100 is provided with a second limiting groove, and the second electromagnet 12 is disposed in the second limiting groove and can move along the extending direction of the second limiting groove.
In the above embodiment, the first limiting groove 31 can better limit the moving position of the first electromagnet 11, so that the first electromagnet 11 can better move towards the second electromagnet 12, and the elastic member 200 forms the bulge 500 to better protect the device.
Similarly, the second limiting groove can better limit the moving position of the second electromagnet 12, so that the second electromagnet 12 can better move towards the first electromagnet 11, and the elastic member 200 can form the bulge 500 to better protect the device.
