Detailed Description

The present invention will be described in further detail with reference to the following detailed description and accompanying drawings.

Referring to fig. 1 and fig. 2, an anti-falling device includes a connecting base 4 for connecting and fixing with a device, and two protection frames disposed at two side ends of the connecting base 4, each protection frame including at least three protection frame units 5. At least three protection frame units 5 of every protection frame make on this plane three protection frame units 5's incorgruous popup can realize the 180 degrees expansion of protection range, and the two sides all set up protection frame then realize protection mechanism's both sides protection, realize 360 degrees protections promptly. The anti-falling device also comprises a movable elastic rod 1 for movably connecting the connecting seat 4 with each protective frame unit 5, and the movable elastic rod 1 plays a role in supporting and pushing each protective frame unit 5; a closed state and an elastic open state are formed between the connecting seat 4 and the protective frame; in a closed state, the connecting seat 4 is tightly matched with the protective frame/protective frame unit 5, and the movable elastic rod 1 is hidden between the two; in the springing-open state, the connecting seat 4 is separated from the protective frame unit 5 and is connected with the protective frame unit through the movable elastic rod 1; the anti-falling device further comprises an induction module 6 which is embedded in the connecting seat 4 and used for inducing a falling state and controlling the connection between the connecting seat 4 and the protective frame unit 5 to be changed from a closed state to an open state when a falling condition is induced.

From the closed state to the flick state, the protective frame unit 5 is popped up by the lifting of the movable elastic rod 1; the pop-up state is converted into the close state, and the protection frame unit 5 can be folded by pressing the protection frame unit by hand.

In the closed state, the edge ends of the protection frame units 5 are in contact and spliced to form a protection frame of a closed structure (as shown in the embodiment shown in fig. 1 and 3, the protection frame formed by splicing the protection frame units 5 is a rectangular closed frame, and two protection frames are formed by four protection frame units 5), so that the overall appearance is smooth and consistent, and corners of matching surfaces and the like are hidden; the connecting seat 4 and the protection frame unit 5 are changed from a closed state to an elastic open state, and the protection frame unit 5 has transverse displacement and longitudinal displacement simultaneously by taking the connecting seat 4 as a reference. The vertical displacement of the two protective frames realizes the protection in the up-down direction, and the horizontal displacement realizes the protection in the front-back, left-right direction. On the basis of the reverse pushing, the outward pushing direction of the movable elastic rod 1 is not upward forward pushing but obliquely outward pushing.

In practice, as shown in fig. 2, 4, 6 and 7, the end portions of the adjacent protection frame units 5 in the same protection frame are respectively provided with a connecting rod 3 for filling the gap between the protection frame units 5, and at least one protection frame unit 5 of the two protection frame units 5 corresponding to one connecting rod 3 is provided with a corresponding embedded sliding groove 2 for hiding/accommodating the connecting rod 3 in a closed state. In this way, the respective protection frame units 5 are also connected to each other by the link rods 3 in the sprung state. The function of the connecting rod 3 is not only guiding, making each protecting frame unit 5 more stable and firm, ensuring the appearance of the product in the spring-open state to be round, but also more important, from the small-sized protecting frame in the closed state to the large-sized protecting frame formed by the protecting frame units 5 in the spring-open state and the connecting rod 3, generating longitudinal displacement/protection under the push of the movable elastic rod 1, and generating transverse expansion/protection in the process of size enlargement.

When the device is implemented, the connecting rod 3 is matched with the embedded sliding groove 2 in shape, and the section of the matching surface is set to be a non-circular surface, so that longitudinal guiding is realized, and axial deflection can be prevented. (where a non-circular section of the mating surface, when implemented, can also be replaced by more than two circular section of the connecting rod embedded sliding groove.)

in practice, the sensing module 6 includes a power supply for supplying power and an electronic sensor for sensing falling (acceleration state in the direction of free fall)/calculating falling time and controlling the action of the movable elastic rod 1. The electronic sensor is an electronic acceleration sensor/an electronic gyroscope/an electronic inertia sensor.

When the method is implemented, the movable elastic rod 1 is controlled to act, and the method comprises the following steps: when the sensing module 6 senses a falling condition (the falling condition is judged by monitoring the acceleration and the direction of the acceleration, and when a free-fall motion occurs, the falling is determined to be a falling state, certainly, considering the air resistance, when the acceleration in the direction of the free-fall is greater than, equal to or slightly less than the gravity acceleration, the falling state can be considered to be a falling state, the falling condition can be judged to be a false acceleration state such as rapid movement, rapid movement of a riding vehicle, shaking of a mobile phone held by an arm and the like), and when the time reaches a preset value (the false acceleration condition caused by bounce and vibration during motion is avoided, the preset value can be set according to requirements, such as setting a user who is engaged in conventional work as 1 second, setting a user who is engaged in outdoor work of sports as 2 seconds, and avoiding false protection in the conventional work, and can also be set to be adjusted by a plurality of gears such as 1 second of conventional gear, 2 seconds, a plurality of gears of common user adjustment, and the like, The limit movement gear is 3 seconds, and the closing gear is adopted; certainly, still can set up human body sensor when needing, when having the human body in sensing a plurality of centimetre scopes, any condition does not think that the cell-phone has danger, when having no human body in a plurality of centimetre scopes, when the time of falling reaches the less value, thinks that the cell-phone has danger promptly), carries out protection frame unit 5 and pops out the protection.

During the implementation, can consider to set up static induction system in cell-phone shell department, when having the human touch promptly, sense static, do not think promptly and be in the state of falling, sense the condition of falling at the response module, do not sense the human touch again. And opening the protection device when the combined falling time reaches a preset value.

When the falling detection device is implemented, the sensing module 6 can be a mechanical sensor and a transmission mechanism, and when the mechanical sensor senses the acceleration of the falling state, the transmission mechanism drives each movable elastic rod 1 to act.

The energy storage output by the movable end of the trigger torsion spring 8 acts on the lever transmission mechanism 9, so that the hook 10 at the other end releases the movable arm of the torsion spring which provides the elastic force source. The lever transmission mechanism 9 comprises a main rod with one end serving as a collision excitation end and at least two hook trigger levers; as shown in fig. 6, the main rod is a straight rod capable of sliding axially, one end of the main rod is a collision head which collides with the movable end of the trigger torsion spring 8, and the other end of the main rod is a pushing block; the hook trigger lever is a lever with a corner, the middle part of the hook trigger lever is hinged on one end of the connecting seat 4, the hook 10 is arranged, and the other end of the hook trigger lever is in contact fit with the pushing block; the main rod slides axially, and meanwhile, the pushing block pushes one end of the hook trigger levers, so that each hook trigger lever deflects along the hinge shaft, each hook 10 is separated from the movable arm of the torsion spring providing the elastic force source, and the protection frame unit 5 is ejected.
