referring to fig. 2, 5, 6, 7 and 8, the locking mechanism 7 is disposed in the handset main body 4, and includes a slider 703 and a return spring 707, the slider 703 is defined by a track 705 and has a linear moving stroke, and the return spring 707 is used for driving the slider 703 to return to the stroke beginning end; a locking pin 702 and a crank arm 706 are fixed on the sliding block 703, the outer end of the locking pin 702 is spherical, and a positioning pit 701 is formed on the inner side wall of the anti-falling frame 3; when the slider 703 is located at the stroke start end, the outer end of the locking pin 702 extends out of the mobile phone main body 4 and can cooperate with the positioning pit 701 to lock the anti-falling frame 3 at the stroke start end, even if the smart phone maintains the initial mode; when the slider 703 is located at the end of the stroke, the locking pin 702 cannot be engaged with the positioning hole 701 to unlock the anti-falling frame 3, and then the smart phone is automatically switched to the anti-falling mode; a pusher dog 708 is fixed on an output shaft 14 of the motor 13 through an eccentric shaft 15, so that the pusher dog 708 can rotate along with the output shaft 14, an angle limiting mechanism 16 and a reset spring 17 are arranged on the output shaft 14, so that the pusher dog 708 has a swing stroke around the eccentric shaft 15 and can automatically reset to the beginning end of the stroke, and the central shafts of the eccentric shaft 15 and the output shaft 14 are parallel; in the process of one forward rotation of the output shaft 14, after the pusher dog 708 is in contact with the crank arm 706, the dragging crank arm 706 drives the slider 703 to move to the stroke end, and then the pusher dog 708 is separated from the crank arm 706; in the process of one reverse rotation of the output shaft 14, after the pusher dog 708 is contacted with the crank arm 706, the pusher dog is forced to swing towards the stroke end without driving the crank arm 706 to generate displacement, and then the pusher dog 708 is separated from the crank arm 706; in short, the locking mechanism 7 can maintain the smartphone in the initial mode, as shown in fig. 7, after the output shaft 14 of the motor 13 rotates forward for at least one turn, the locking mechanism 7 will release the locking on the anti-falling frame 3, so that the smartphone is switched to the anti-falling mode, as shown in fig. 8, the station state of the locking pin 702 will not be changed during the reverse rotation of the output shaft 14 of the motor 13;
referring to fig. 2, 3, 7 and 8, the gravity acceleration sensor 6 is disposed inside the mobile phone body 4, and can perform signal transmission with the main processor, so that the main processor can monitor the free-falling state of the mobile phone body 4 by means of the gravity acceleration sensor 6; a time threshold value T1 is preset in the main processor, and when and only when the main processor monitors that the mobile phone main body falls in a free-fall motion and the falling duration time T2 is equal to T1, the output shaft 14 of the motor 13 rotates forwards and rotates at least one circle to prompt the locking mechanism 7 to release the locking of the anti-falling frame 3, so that the smart phone is switched into an anti-falling mode, namely the anti-falling frame 3 and the four anti-falling legs 2 quickly reach respective stroke terminals to prevent any part of the mobile phone main body 4 from directly contacting with the ground; when the vibration component provides a vibration effect for the smart phone, the main processor enables the output shaft 14 of the motor 13 to rotate reversely to drive the eccentric block 12 to generate the vibration effect, so that the station state of the locking pin 702 can be ensured not to change, namely, the smart phone is ensured not to be switched from an initial mode to an anti-falling mode during vibration in a normal use process; after the main processor stops the operation of the motor 13, the pawl 708 is positioned so as not to prevent the slider 703 from being reset to the stroke start end, thereby ensuring that the locking mechanism 7 has the capability of locking the drop-proof bezel 3 again.
This based on gravity sensing realizes preventing the theory of operation of smart mobile phone that falls and prevents falling the mechanism and does:
referring to fig. 1, in a normal use process, the locking mechanism 7 provides a locking function for the anti-falling frame 3, so that the smart phone is kept in an initial mode, namely, the anti-falling frame 3 is sleeved around the outer side of the mobile phone main body 4, the anti-falling feet 2 are accommodated in four corners of the mobile phone main body 4, the overall appearance of the smart phone is smooth, the appearance, the use mode and the hand-held feeling of the smart phone are smaller than those of the existing smart phone, and the anti-falling frame 3 is sleeved around the mobile phone main body 4 to play a certain protection role. Referring to fig. 3, 4, 7, and 9, when the main processor monitors that the smart phone falls and reaches a certain height, which indicates that there is a risk of breaking, the main processor will rotate the output shaft 14 of the motor 13 forward at least one turn, i.e. drive the locking mechanism 7 to unlock the anti-falling frame 3, the anti-falling frame 3 and the four anti-falling legs 2 will move to respective travel terminals quickly and timely under the action of respective elastic components, so that the smart phone reaches the anti-falling mode, so as to prevent the smart phone body 4 from directly contacting the ground, because the anti-falling frame 3 is frame-shaped and is rotatably connected with the smart phone body 4, after contacting the ground, the anti-falling legs 2 can deform and rotate to a certain extent, and the design of the anti-falling legs 2 makes the anti-falling legs 2 stretch to a certain extent, based on the above characteristics of the anti-falling frame 3 and the anti-falling legs 2, when the smart phone falls to the ground, the anti-falling frame 3 and the anti-falling legs 2 can well buffer the impact force, so as to reduce the stress of the mobile phone body 4, thereby ensuring the safety of the internal elements and the screen 5, and finally realizing good anti-falling performance, and avoiding the screen 5 being broken to the maximum; under the anti-falling mode, when the anti-falling frame 3 is manually driven to move towards the stroke starting end, the outer end of the locking pin 702 is stressed to drive the sliding block 703 to move towards the stroke terminal direction, when the anti-falling frame 3 reaches the stroke starting end, under the action of the reset spring 707, the outer end of the locking pin 702 automatically falls into the positioning pit 701 to lock the anti-falling frame 3, that is, the smart phone is restored to the initial mode.
Referring to fig. 1 and 2, generally speaking, according to the design habit of the existing smart phone, the functional components such as the on-off key, the volume key, the earphone hole, and the power hole are disposed on the sidewall of the phone body 4, and the smart phone should avoid the functional components being blocked by the falling-proof frame 3 in the initial mode, and in the specific implementation process, the functional components such as the on-off key, the volume key, the earphone hole, and the power hole can be disposed in the side area of the phone body 4 that the falling-proof frame 3 cannot cover, and meanwhile, corresponding notches and holes can be formed in the falling-proof frame 3, so as to ensure that the functional components located on the sidewall of the phone body 4 can be exposed.
Referring to fig. 2, 3 and 10, in the smart phone for implementing fall prevention based on gravity sensing, the specific matching structure among the fall prevention frame 3, the phone body 4, the support shaft 1 and the elastic component has various embodiments, and is preferably implemented in the following manner:
the middle parts of two opposite sides of the mobile phone main body 4 are respectively provided with a shaft seat 9, the support shafts 1 are matched with the shaft seats 9 and can only relatively rotate, two side parts of the anti-falling frame 3 are respectively connected with the two support shafts 1, so that the anti-falling frame 3 can integrally rotate around the shaft seats 9, and the anti-falling frame 3 can only rotate within a rotation stroke by arranging a limiting mechanism between the anti-falling frame 3 and the mobile phone main body 4; the elastic part at the supporting shaft 1 adopts a torsion spring 10 which is arranged in the shaft seat 9 and surrounds the supporting shaft 1, and can drive the supporting shaft 1 to drive the anti-falling frame 3 to rotate from the stroke starting end to the stroke terminal end; in order to ensure that the smart phone can rotate towards the direction of the stroke starting end as much as possible after the anti-falling frame 3 lands when falling in the anti-falling mode, so as to buffer the impact force by means of the elastic force of the elastic component, the rotation angle corresponding to the rotation stroke of the anti-falling frame 3 should be smaller than 90 degrees.
Referring to fig. 2, 3 and 11, in the smart phone for implementing fall prevention based on gravity sensing, the specific matching structure of the phone body 4, the seat 8, the fall prevention leg 2 and the elastic component has various embodiments, and the following embodiments are preferably used:
the placing seat 8 is drawer-shaped and is provided with a notch 801, and the notch 801 is positioned on the side wall of the corner of the mobile phone main body 4; the anti-falling foot 2 is composed of a leg part 202 and a foot part 201 which are fixedly connected, the leg part 202 is limited in the placing seat 8 and can slide without being separated from the placing seat 8, and therefore the anti-falling foot 2 can slide in a linear moving stroke; an inner cavity is formed in the inner end of the leg part 202, an elastic component for driving the anti-falling foot 2 to move towards the stroke terminal is arranged between the inner cavity and the bottom of the placing seat 8, and the elastic component is a spring or an elastic sheet 11; when the falling-proof feet 2 are positioned at the initial end of the stroke, the leg parts 202 are completely positioned in the placing seat 8, the inner ends of the leg parts 202 are contacted with the bottom of the placing seat 8, the elastic parts are in a compressed state and are contained in the inner cavities of the leg parts 202, and the notch 801 is blocked by the foot parts 201, so that the corners of the mobile phone main body 4 are complete and smooth; when the smart phone is in the initial mode, the foot part 201 is located inside the anti-falling frame 3 and cannot move, so that the anti-falling foot 2 is kept at the beginning of the stroke;
after the mobile phone main body 4, the placing seat 8, the falling-preventing legs 2 and the elastic component adopt the above structure, the sizes of the legs 202 and the placing seat 8 can be reduced to the maximum extent to reduce the occupation of the internal space of the mobile phone main body 4, and the sizes of the legs 201 can be increased appropriately to improve the protection performance of the matching of the falling-preventing legs and the falling-preventing frame 3 in the falling-preventing mode.
As shown in fig. 4 and 9, it is known that when a mobile phone falls, the landing position of the mobile phone is uncertain, but in the implementation process of the smart phone, as long as the overall dimension of the mobile phone body 4 is combined, the size of the anti-falling frame 3 and the anti-falling foot 2, the relative position of the anti-falling frame 3, the anti-falling foot 2, and the mobile phone body 4 in the anti-falling mode, and other structural parameters are scientifically debugged, so that any part of the mobile phone body 4 cannot be in direct contact with the ground when the smart phone falls to the ground, that is, any part of the mobile phone body 4 that can be prevented from falling by the anti-falling frame 3 and the anti-falling foot 2 in the anti-falling mode can be in direct contact with the ground, and the mobile phone body 4 is provided with an all-directional anti-falling protection without a dead angle.
Referring to fig. 5-8, in the smart phone for implementing anti-falling based on gravity sensing, the motor 13 has two functions, that is, as shown in fig. 8, in the normal use process, the motor 13 provides a vibration effect for the smart phone through the reverse rotation of the output shaft 14, and, as shown in fig. 7, when the smart phone falls, the motor 13 drives the locking mechanism 7 to unlock the anti-falling frame 3 through the forward rotation of the output shaft 14, so that the smart phone is switched to the anti-falling mode, which can achieve two purposes at a time, thereby greatly reducing the manufacturing cost of the smart phone and improving the cost performance of the smart phone; in the foregoing description, the output shaft 14 has two working states of forward rotation and reverse rotation, so-called "forward rotation" and "reverse rotation" are relative terms, and are only a setting of the rotation state of the output shaft 14 for convenience of description, when the output shaft 14 rotates in one direction, the finger 708 is driven by the output shaft 14, and the draggable crank 706 drives the slider 703 to move from the stroke beginning end to the stroke end, at this time, the rotation state of the output shaft 14 is forward rotation, otherwise, reverse rotation; the relative positions of the output shaft 14, the finger 708, the crank 706, and other related components are not limited to one type, and thus the actual rotational direction of the output shaft 14 corresponding to the so-called normal rotation is not necessarily the same in different embodiments.
In the above-mentioned smart mobile phone that prevents falling based on gravity sensing realization, when vibrations subassembly provides vibrations effect for the smart mobile phone, pusher dog 708 can be high frequency and crank arm 706 produce collision and friction, the unfavorable effect of indirect production is, the smart mobile phone vibrations in-process can be accompanied with high frequency noise, pusher dog 708 and crank arm 706 contact site wear and tear easily and cooperate unstablely, in order to improve above-mentioned problem, can go on further improvement to the cooperation mode between pusher dog 708 and the crank arm 706, concrete improvement structure is:
a rubber roller 704 capable of freely rotating is arranged on the crank arm 706, and the pusher dog 708 only indirectly acts on the crank arm 706 through the rubber roller 704 in the forward rotation and reverse rotation processes of the output shaft 14; therefore, when the vibration component provides a vibration effect for the smart phone, the collision between the pusher dog 708 and the rubber covered roller 704 does not generate a violent sound, and meanwhile, because the friction mode in the relative movement process of the pusher dog 708 and the rubber covered roller 704 is rolling friction, the abrasion speed of the contact part between the pusher dog 708 and the rubber covered roller 704 is low, and the service life of stable matching of the pusher dog 708 and the rubber covered roller 704 is ensured; in addition, because the friction resistance of the pusher dog 708 and the rubber covered roller 704 in the relative movement process is small, the driving force provided by the motor 13 for providing a vibration effect for the smart phone and switching the smart phone into the anti-falling mode is reduced to a certain extent, and the work of the motor 13 is more energy-saving and stable.
In the smart phone for realizing the anti-falling function based on the gravity sensing, the gravity acceleration sensor 6 is one of core components for realizing the anti-falling function, although the manufacturing cost is expensive, the gravity acceleration sensor can also have other functions besides the anti-falling function, the cost performance of the smart phone can be improved by making the best use of the gravity acceleration sensor, and the cost investment required for realizing the anti-falling function is reduced to a certain extent; meanwhile, in a plurality of high-end existing smart phones, the gravity acceleration sensor 6 is a standard component, and the function of the gravity acceleration sensor can be directly expanded to be used in the anti-falling function, so that the scheme is easier to implement, and the implementation cost is lower.
In the smart phone for realizing the anti-falling based on the gravity sensing, a time threshold value T1 is preset in a main processor, and the time threshold value T1 is used as a time reference value for judging whether an anti-falling mode is started or not by the smart phone; when the mobile phone main body 4 falls in a free-fall motion and the falling duration time T2 is less than T1, it indicates that the falling height of the smart phone is small, and there is no risk of breaking, and it may be intended by the user, for example, people are usually used to throw the mobile phone directly on a bed or a sofa, in such a case, the smart phone is not switched to the anti-falling mode, so as to avoid unnecessary trouble to the user; when the mobile phone main body 4 falls in a free-fall motion and the falling duration time T2 is equal to T1, it indicates that the falling height of the smart phone is large and there is a possibility of continuing accelerated falling, in which case the risk of being broken is extremely high, and the smart phone switches to the anti-falling mode to improve the anti-falling performance. As for the specific value of the time threshold T1, a reasonable value can be determined by performing multiple debugging operations in combination with the use habits of the public, the anti-falling performance of the smartphone in the initial mode, the time required for the smartphone to reach the anti-falling mode from the initial mode, and other factors.
In the smart phone for realizing the anti-falling based on the gravity sensing, the anti-falling frame 3 and the anti-falling feet 2 can be made of low-density and high-strength materials and are combined with a compact structural design, so that the appearance difference between the smart phone and the conventional mobile phone is further reduced, the use habit of the public is met, and the adverse effects of the anti-falling frame 3 and the anti-falling feet 2 on the portability and the convenience of operation of the smart phone are reduced; simultaneously prevent falling frame 3 and prevent falling the preparation material that foot 2 adopted and still should have good elasticity to the cushioning effect to impact force when the smart mobile phone falls to the ground is further improved.
Referring to fig. 4 and 9, based on the structure adopted by the smart phone, when the smart phone falls to the ground, the stress on the phone body 4 is mainly concentrated on the contact portions with the two support shafts 1 and the four anti-falling legs 2, so in order to further improve the anti-falling performance of the smart phone, the phone body 4 should adopt means such as thickening or adding reinforcing ribs to ensure the local strength at the portions where the two support shafts 1 and the four anti-falling legs 2 are arranged, so as to improve the overall service life of the smart phone.
The smart mobile phone is compact in structure, excellent in anti-falling performance, capable of considering other basic performances of the mobile phone, consistent in appearance with mainstream design of the existing mobile phone, simple in structure of anti-falling functional parts, easy to implement and strong in stability, and meanwhile, the anti-falling function is completely realized based on a mechanical principle, the use times of the anti-falling function is not limited, and therefore the smart mobile phone has a good implementation prospect.
Example 2
People usually like to install the simple support at the rear side of the mobile phone, and the mobile phone can be transversely and obliquely placed on a desktop by the aid of the simple support, so that the mobile phone does not need to be held by a hand for a long time when being operated for watching movies and the like, and people can enjoy the effects of relaxing and comfort. At present, the simple support of generally comparatively high-quality adopts metal material to make usually, will certainly influence the portability of cell-phone to a certain extent, and simple support adopts colloid and cell-phone bonding fixed usually simultaneously, and the connected mode is unstable, very easily breaks away from the cell-phone, and can leave the glue trace that is difficult to dispel behind the drop back at the cell-phone rear side. The embodiment further improves the structure of the smart phone disclosed in the embodiment 1, and can overcome the defects existing in the matching use process of the existing mobile phone and the simple support. The adopted scheme is as follows:
referring to fig. 12, 13 and 14, the two support shafts 1 are respectively located in the middle of the upper end and the middle of the lower end of the mobile phone body 4; the anti-falling frame 3 is composed of an active frame 301 and a passive frame 302 which are symmetrical in shape and are both arc-shaped, two ends of the active frame 301 and two ends of the passive frame 302 are supported by two supporting shafts 1, so that the active frame 301 and the passive frame 302 respectively have a rotation stroke, the locking mechanism 7 and the elastic components at the two supporting shafts 1 only act on the active frame 301, and a one-way synchronization mechanism 18 is arranged between the active frame 301 and the passive frame 302; when the smart phone is in an initial mode, the active frame 301 and the passive frame 302 are located at the respective stroke starting ends and respectively constrain the two adjacent anti-falling feet 2 at the stroke starting ends, that is, the anti-falling frame 3 is located at the stroke starting end as a whole; when the locking mechanism 7 unlocks the active frame 301, the active frame 301 drives the passive frame 302 to rotate together with the passive frame to respective stroke terminals through the one-way synchronization mechanism 18, that is, the anti-falling frame 3 integrally rotates to the stroke terminals, and the smart phone switches to the anti-falling mode, where the active frame 301 and the passive frame 302 are located on the front side and the rear side of the mobile phone main body 4, respectively; in the initial mode, the passive frame 302 can be manually rotated to the rear side of the mobile phone body 4, and the unidirectional synchronization mechanism 18 does not drive the active frame 301 to rotate in the process, and then the mobile phone body 4 can be supported by the passive frame 302 at the rear side thereof and the anti-falling legs 2 extending from two corners to be placed on the desktop in a laterally inclined manner.
After the smart mobile phone that realizes preventing falling based on gravity sensing adopts above-mentioned structural design, prevent falling frame 3 not only play the guard action in preventing falling the mode, still can carry out simple manually operation to passive frame 302, and make it provide the support for cell-phone main part 4 from the rear side as simple and easy support, make cell-phone main part 4 can transversely incline and place on the desktop, through the angle of adjusting passive frame 302 and cell-phone main part 4, can adjust the inclination that cell-phone main part 4 placed when the desktop, convenient and practical. Meanwhile, when the smart phone is held by hand, the passive frame 302 can be manually rotated to the rear side of the mobile phone main body 4, so that the passive frame 302 is sleeved on the hand, and a certain anti-falling effect is achieved. In addition, when the people is for rotating passive frame 302 to cell-phone main part 4 rear side, two that correspond prevent falling foot 2 will automatic movement to the stroke terminal, though two that correspond under this state prevent falling foot 2 and extend to cell-phone main part 4 outsidely, nevertheless do not influence the result of use that the smart mobile phone placed behind the desktop, on the contrary two that stretch out prevent falling foot 2 and can play landing leg and skid-proof effect, make people's more comfortable 5 pictures of watching screen.
Referring to fig. 12 and 13, in the above structure, a one-way synchronizing mechanism 18 is disposed between the active frame 301 and the passive frame 302, and the one-way synchronizing mechanism 18 is disposed in such a manner that, on one hand, when the smart phone switches from the initial mode to the anti-falling mode, after the locking mechanism 7 unlocks the anti-falling frame 3, the one-way synchronizing mechanism 18 can ensure that the active frame 301 and the passive frame 302 rotate synchronously, and further ensure that the anti-falling frame 3 can integrally reach the stroke end position; on the other hand, when the smartphone is in the initial mode, the one-way synchronization mechanism 18 allows the passive bezel 302 to rotate to the rear side of the phone body 4 while the active bezel 301 is kept at the stroke start end, so as to achieve the purpose of using it as a simple stand;
referring to fig. 12, 13 and 15, based on the above arrangement of the one-way synchronizing mechanism 18, the prior art has many embodiments, for example, the one-way synchronizing mechanism 18 may be formed by an arc-shaped groove 181 and a convex pillar 182 which are slidably engaged with each other, the arc-shaped groove 181 and the convex pillar 182 are respectively disposed on two opposite sides of the hinge joint of the driving frame 301 and the driven frame 302, and the central axes of the arc-shaped groove 181 and the supporting shaft 1 coincide; in the initial mode, when the driving frame 301 rotates from the stroke start end to the stroke end, the protruding pillar 182 abuts against the end of the arc-shaped groove 181 to ensure that the driven frame 302 rotates synchronously with the driving frame 301, and when the driven frame 302 is manually rotated, the protruding pillar 182 slides in the arc-shaped groove 181 so that the driven frame 302 does not drive the driving frame 301 to rotate, thereby achieving the above-mentioned purpose of the unidirectional synchronization mechanism 18.
Referring to fig. 14, generally speaking, the passive frame 302 only needs to be located at the rear side of the mobile phone main body 4 in the anti-falling mode and when used as a simple stand, and should be located at the beginning of the journey in most other times, for example, the passive frame 302 sometimes separates from the beginning of the journey automatically during the normal use of the smart phone, which will bring a certain trouble to the user. In the smart phone, in the initial mode, the two falling-resistant feet 2 corresponding to the passive frame 302 exert a certain acting force on the passive frame, so as to provide a certain positioning function for the passive frame 302 located at the start of the stroke, and the passive frame 302 cannot be separated from the start of the stroke; meanwhile, in order to improve the positioning effect of the falling-prevention legs 2 on the passive frame 302, the passive frame 302 and the corresponding two falling-prevention legs 2 can be further improved:
as shown in fig. 16, two positioning slots 19 are formed on the inner side of the passive frame 302, and spherical positioning protrusions 20 are respectively disposed on the two falling-preventing legs 2 corresponding to the passive frame 302; when the passive frame 302 and the two corresponding anti-falling legs 2 are located at the initial end positions, the two anti-falling legs 2 abut against the inner side of the passive frame 302 and are bound at the initial end of the stroke by the passive frame 302, and meanwhile, the two positioning protrusions 20 just fall into the two positioning grooves 19, so that the passive frame 302 is limited at the initial end of the stroke;
in the above structure adopted by the passive frame 302 and the two anti-falling legs 2, the two anti-falling legs 2 have a tendency to move towards the stroke end under the action of the elastic component, so the structure formed by the anti-falling legs 2 and the positioning protrusions 20 can be regarded as a ball plunger, and can provide a proper positioning function for the passive frame 302; on one hand, in the normal use process of the smart phone, the passive frame 302 is kept at the stroke starting end and cannot be separated automatically, and on the other hand, when the anti-falling mode is switched, the passive frame 302 is driven by the active frame 301 to be separated from the positioning effect of the anti-falling feet 2, so that the passive frame 302 can rotate synchronously with the active frame 301; in addition, the passive frame 302 can be manually driven to separate from the positioning function of the falling-proof foot 2, so that the passive frame 302 can be rotated to the rear side of the mobile phone main body 4 to serve as a simple support for use.
In addition, as shown in fig. 14, when the passive frame 302 is rotated to the rear side of the mobile phone main body 4 to be used as a simple stand, it and the mobile phone main body 4 should be able to maintain an adjusted angle, so that the mobile phone main body 4 can stably maintain a desired tilt angle; in the specific implementation process, the above effects can be better achieved by reasonably adjusting the rotation resistance of the passive frame 302.
Example 3
Referring to fig. 14, in the smart phone based on gravity sensing for implementing falling prevention disclosed in embodiment 2, when the passive frame 302 is used as a simple support, the two corresponding falling-prevention legs 2 extend to the outside of the host body, although this phenomenon does not substantially affect the using effect of the smart phone, the appearance of the smart phone in this state is not acceptable to the public. Therefore, in this embodiment, a further improvement is made on the basis of the structure of the smart phone disclosed in embodiment 2 to overcome the foregoing deficiency, and the adopted improved structure is as follows:
referring to fig. 17 and 18, the mobile phone body 4 is provided with a check claw 21 at each of the two seats 8 corresponding to the passive frame 302, and each of the two corresponding anti-falling legs 2 is provided with a check groove 23; the two check claws 21 are respectively connected with the adjacent supporting shafts 1 through a pull wire 22, and the two supporting shafts 1 and the driving frame 301 cannot rotate relatively; when the driving frame 301 is at the initial position, the pull wire 22 does not pull the anti-falling foot 2, and after the anti-falling foot 2 moves to the initial end of the stroke, the anti-falling foot 21 automatically falls into the anti-falling groove 23 to prevent the anti-falling foot 2 from moving towards the terminal direction of the stroke; when the driving frame 301 rotates from the stroke beginning to the stroke end, the anti-falling claws 21 are pulled by the tension lines 22 and cannot be matched with the anti-falling grooves 23, and then the two anti-falling claws 21 do not form an obstacle to the movement of the two anti-falling feet 2.
Therefore, as shown in fig. 17, 18, and 19, when the smart phone is in the initial mode, and the passive frame 302 is rotated to the rear side of the phone main body 4 to serve as a simple support, since the active frame 301 is located at the beginning of the stroke, the two anti-falling legs 2 corresponding to the passive frame 302 are still kept at the beginning of the stroke under the action of the check claws 21 and the check grooves 23, and do not extend to the outside of the phone main body 4, so as to ensure that the shape of the smart phone conforms to the aesthetic taste of the public under this state; when the smart phone switches from the initial mode to the anti-falling mode, the active frame 301 and the passive frame 302 rotate from the stroke start end to the stroke end, and the two supporting shafts 1 pull the two anti-falling claws 21 to disengage from the two anti-falling grooves 23 through the pull wires 22, so as to release the locking effect on the corresponding anti-falling legs 2, thereby ensuring that the two anti-falling legs 2 corresponding to the passive frame 302 can move to the stroke end.
Example 4
Referring to fig. 12 and 16, in the implementation of the smart phone based on gravity sensing for implementing drop prevention disclosed in example 2, it is mentioned that, in the initial mode of the smart phone, the passive bezel 302 may be provided with a certain positioning function by the drop-prevention foot 2, so as to ensure that the passive bezel 302 does not automatically separate from the beginning of the stroke, and an improved structure for improving the positioning effect based on the matching relationship between the drop-prevention foot 2 and the passive bezel 302 is also disclosed. For example, because the falling-prevention leg 2 provides a certain positioning function when the passive frame 302 is located at the beginning of the stroke, when the smart phone switches from the initial mode to the falling-prevention mode, a larger driving force needs to be provided for the passive frame 302 to overcome the positioning function, which obviously improves the requirement on the elasticity of the elastic component, and also improves the strength requirements on the relevant components such as the support shaft 1, the active frame 301, the passive frame 302, the mobile phone main body 4, the locking mechanism 7, and the like, and usually needs to adopt a mode of increasing the size of the components to improve the performance, so that the components are no longer small and compact; in addition, this smart mobile phone prevents falling the function and designs based on circulated use, can manually restore to initial mode under preventing falling the mode, after improving back shaft 1 department elastomeric element elasticity for the smart mobile phone is no longer simple and convenient from preventing falling the mode and restoring to initial mode's manual operation. Therefore, the present embodiment is further improved on the basis of the structure of the smart phone disclosed in embodiment 2, so as to overcome the above-mentioned disadvantages. The adopted specific scheme is as follows:
referring to fig. 20 and 21, a positioning mechanism is arranged between the passive frame 302 and the mobile phone main body 4, the positioning mechanism is composed of a magnetic sheet 25 fixed on the passive frame 302, an iron sheet 24 fixed on the mobile phone main body 4, and a micro-electromagnet 26 located in the mobile phone main body 4 and used for magnetizing the iron sheet 24, and the power-on state of the micro-electromagnet 26 is controlled by the main processor; in the initial mode, when the micro-electromagnet 26 is in the non-energized state, the magnetic sheet 25 and the iron sheet 24 are closely adsorbed to position the passive frame 302 at the initial end of the stroke, and when and only when the main processor monitors that the mobile phone main body 4 falls down in a free-fall motion and the falling duration time T2 is equal to T1, the micro-electromagnet 26 is energized briefly, and at that time, the micro-electromagnet 26 generates a magnetic field instantly to drive the magnetic sheet 25 to be separated from the iron sheet 24, namely, the passive frame 302 is driven to rotate towards the final end of the stroke; when the micro-electromagnet 26 is in a non-electrified state, the passive frame 302 can be manually driven to break away the attraction between the magnetic sheet 25 and the iron sheet 24 and rotate backwards, and the simple bracket can be used;
after the smart phone for realizing the anti-falling based on the gravity sensing adopts the structure, the smart phone is in an initial mode in the normal use process, the micro electromagnet 26 is in an unpowered state, and the positioning mechanism can provide proper positioning force for the passive frame 302, so that the passive frame 302 is prevented from automatically separating from the stroke starting end; when the smartphone is switched from the initial mode to the anti-falling mode, the micro-electromagnet 26 is in the power-on state, and at this time, the positioning mechanism does not prevent the passive frame 302 from rotating to the stroke end, but applies a certain assistance force to enable the passive frame 302 to rotate to the stroke end more quickly, so that the driving force required to be provided for the passive frame 302 when the initial mode is switched to the anti-falling mode is reduced, and the technical problem to be solved in the embodiment is solved.
