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 capable of preventing from falling should avoid the functional components being blocked by the falling-preventing 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 are disposed in the side area of the phone body 4 that the falling-preventing frame 3 cannot cover, and meanwhile, corresponding notches and holes can be disposed on the falling-preventing 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. 5 and 6, in the above-mentioned smart phone capable of preventing falling, the specific matching structure among the falling-preventing frame 3, the phone body 4, the supporting shaft 1 and the elastic component has various embodiments, and is preferably implemented as follows:

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 anti-falling frame 3 can rotate in the direction of the stroke starting end as much as possible after the anti-falling frame 3 lands when the anti-falling smart phone falls 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 less than 90 degrees.

Referring to fig. 5 and 7, in the crash-proof smart phone, the specific matching structure of the phone body 4, the seat 8, the crash-proof legs 2 and the elastic component has various embodiments, and the following embodiments are preferably adopted:

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 setting seat 8 and can slide without being separated from the setting seat 8, and therefore the anti-falling foot 2 can slide in a linear movement 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 part 202 is completely positioned in the placing seat 8, the inner end of the leg part 202 is contacted with the bottom of the placing seat 8, the elastic component is in a compressed state and is contained in the inner cavity of the leg part 202, the foot part 201 seals the notch 801, and the corner part of the mobile phone main body 4 is complete and smooth; when the smart phone capable of preventing falling 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.

Referring to fig. 3 and 4, as is known, when a mobile phone falls, the landing position of the mobile phone is uncertain, but in the implementation process of the anti-falling 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 legs 2, the structural parameters such as the relative positions of the anti-falling frame 3, the anti-falling legs 2 and the mobile phone body 4 in the anti-falling mode are scientifically debugged, so that any part of the mobile phone body 4 cannot be in direct contact with the ground when the anti-falling smart phone falls to the ground, that is, any part of the mobile phone body 4 which can be prevented from falling by the anti-falling frame 3 and the anti-falling legs 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-.

Referring to fig. 2 and 3, in the anti-falling smart phone, the electric locking mechanism 7 is controlled by the main processor to operate, on one hand, the anti-falling frame 3 can be locked at the beginning of the travel to maintain the anti-falling smart phone in the initial mode, and on the other hand, the locking function of the anti-falling frame 3 can be released according to the instruction of the main processor to switch the anti-falling smart phone to the anti-falling mode; in the prior art, the electric lock mechanism 7 can be realized by combining the driving mechanism and the lock mechanism, and has various embodiments and can preferably realize the above functions, but in order to make the structure of the electric lock mechanism 7 more compact and the response speed faster, it is preferable to adopt the following structure:

referring to fig. 8 and 9, the electric locking mechanism 7 includes a sleeve 17 made of soft iron and fixed in the mobile phone body 4, a coil 14 is wound outside the sleeve 17 to form an electromagnet device, and the energization state of the coil 14 is controlled by the main processor; a locking pin 15 passes through the sleeve 17, and the two can move axially relative to each other but can not be separated; the outer end of the locking pin 15 is a spherical end 13, and the inner end is positioned at the inner side of the sleeve 17 and is fixed with an annular permanent magnet 16; a through hole for the spherical end 13 to pass through is formed in the side wall of the mobile phone main body 4, and a positioning pit 12 is formed in the inner side wall of the anti-falling frame 3; when the anti-falling frame 3 is located at the initial end of the stroke and the coil 14 is not electrified, the permanent magnet 16 is adsorbed on the sleeve 17, the spherical end 13 extends out of the mobile phone main body 4 and falls into the positioning pit 12, at the moment, the force provided by the elastic component cannot drive the anti-falling frame 3 to rotate, and the anti-falling smart phone can maintain the initial mode; in the initial mode, if and only if the main processor monitors that the mobile phone main body 4 falls in a free fall motion and the falling duration time T2 is equal to T1, the coil 14 is briefly powered on, and then the sleeve 17 instantly generates a magnetic field to drive the permanent magnet 16 to move inwards, the spherical end 13 is separated from the positioning pit 12 to unlock the anti-falling frame 3, and the smart phone capable of preventing falling is switched to the anti-falling mode; in the anti-falling mode, when the anti-falling frame 3 is manually driven to move towards the stroke starting end, the spherical end 13 is stressed and then retracts inwards by overcoming the suction force between the permanent magnet 16 and the sleeve 17, when the anti-falling frame 3 reaches the stroke starting end, the spherical end 13 automatically falls into the positioning pit 12 to lock the anti-falling frame 3, and the anti-falling smart phone is restored to the initial mode;

after the electric locking mechanism 7 adopts the structure, the electric locking mechanism only consumes electric energy within a short time when the anti-falling mode of the anti-falling smart phone can be switched, and the power of the electric locking mechanism is realized based on the electromagnetic conversion effect, so that the electric locking mechanism 7 has extremely low electric consumption and extremely high response speed in the working process; the sleeve 17 and the locking pin 15 adopt an inserting structure, so that the electric locking mechanism 7 has a compact structure and small volume, and occupies a small space in the mobile phone main body 4; when the intelligent mobile phone capable of preventing falling is manually restored to the initial mode, the electric locking mechanism 7 does not need to be additionally operated, and the operation is convenient and fast.

In the anti-falling smart phone, the gravity acceleration sensor 6 is one of the core components for realizing the anti-falling function, although the cost is high, the gravity acceleration sensor can also have other functions besides the anti-falling function, the cost performance of the anti-falling smart phone can be improved as much as possible, 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 anti-falling smart phone, a time threshold T1 is preset in a main processor, and the time threshold T1 is used as a time reference value for judging whether an anti-falling mode is started or not by the anti-falling smart phone; when the mobile phone main body 4 falls in a free-fall motion and the falling duration T2 is shorter than T1, it indicates that the falling height of the drop-proof smart phone is small, there is no risk of breaking, and it may be intended by the user, for example, when people are usually used to throw the mobile phone directly on a bed or a sofa, the drop-proof smart phone will not be switched to the drop-proof mode in this case, and unnecessary trouble is avoided for the user; when the mobile phone main body 4 falls in a free fall motion and the duration T2 of the fall is equal to T1, it indicates that the falling height of the drop-proof 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 drop-proof smart phone is switched to the drop-proof mode to improve the drop-proof 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 usage habits of the public, the anti-falling performance of the anti-falling smart phone in the initial mode, the time required for the initial mode to reach the anti-falling mode, and other factors.

In the anti-falling smart phone, 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 anti-falling smart phone and the existing smart 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 operation convenience of the anti-falling smart phone are reduced; simultaneously prevent falling frame 3 and the preparation material that prevents falling foot 2 and adopt still should have good elasticity to the cushioning effect to the impact force when the smart mobile phone that can prevent falling falls to the ground is further improved.

Based on this can prevent structure that smart mobile phone adopted that falls, when it falls to the ground, the atress of cell-phone main part 4 mainly concentrates on with two supporting axles 1 and four contact site of preventing falling foot 2, so in order to further improve can prevent preventing falling the smart mobile phone of falling the performance, cell-phone main part 4 should adopt means such as thickening or add the strengthening rib to guarantee above-mentioned local intensity at the position of settling two supporting axles 1 and four of preventing falling foot 2 to improve the whole life of the smart mobile phone that can prevent falling.

This can prevent smart mobile phone that falls compact structure prevents falling the performance excellence, can compromise other essential properties that can prevent the smart mobile phone that falls, and its outward appearance is unanimous with current smart mobile phone's mainstream design, compound masses aesthetic and use custom, and the structure of preventing falling the functional part is comparatively simple, easy implementation and stability are strong, and it prevents falling the function and realizes based on mechanical principle completely simultaneously, prevents that the number of times of use of falling the function does not have the restriction, consequently has good implementation prospect.

Example 2

People generally like installing the simple support at the rear side of the smart phone, and can transversely tilt the smart phone on a desktop by means of the simple support, so that the smart phone does not need to be held by a hand for a long time when watching a film and the like, and people can enjoy the smart phone more easily and comfortably. At present, the simple and easy support of generally comparatively high-quality adopts metal material to make usually, will influence the portability of smart mobile phone to a certain extent, and simple and easy support adopts colloid and smart mobile phone bonding fixed usually simultaneously, and the connected mode is unstable, very easily breaks away from the smart mobile phone, and can leave the glue trace that is difficult to dispel behind the droing behind the smart mobile phone. The embodiment further improves the structure of the anti-falling smart phone disclosed in the embodiment 1, and can overcome the defects existing in the matching use process of the existing smart phone and the simple support. The adopted scheme is as follows:

referring to fig. 10, 11 and 12, 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 main 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 electric 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 capable of preventing falling is in an initial mode, the active frame 301 and the passive frame 302 are located at the respective starting ends of the strokes and respectively constrain the two adjacent falling-preventing feet 2 at the starting ends of the strokes, that is, the falling-preventing frame 3 is located at the starting ends of the strokes as a whole; when the electric locking mechanism 7 unlocks the active frame 301, the active frame 301 drives the passive frame 302 to rotate together with the passive frame 302 to respective stroke terminals through the one-way synchronization mechanism 18, that is, the anti-falling frame 3 rotates integrally to the stroke terminals, and the anti-falling smart phone can be switched to an anti-falling mode, wherein the active frame 301 and the passive frame 302 are respectively located on the front side and the rear side of the mobile phone body 4; 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 can prevent falling adopts above-mentioned structural design, prevent falling frame 3 not only playing 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 of placing cell-phone main part 4 when the desktop, convenient and practical. Meanwhile, when the anti-falling smart phone is held in a 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 will be moved frame 302 and rotate to cell-phone main part 4 rear side, the foot 2 will automatic movement to the stroke terminal will be prevented falling by two of correspondence, though two of correspondence are prevented falling the foot 2 and are extended to cell-phone main part 4 outside under this state, but do not influence the result of use that the smart mobile phone that can prevent falling was placed behind the desktop, on the contrary, the two of stretching 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. 10 and 11, in the above structure, a one-way synchronization mechanism 18 is disposed between the active frame 301 and the passive frame 302, and the one-way synchronization mechanism 18 is disposed in such a way that, on one hand, when the anti-falling smart phone is switched from the initial mode to the anti-falling mode, after the electric locking mechanism 7 unlocks the anti-falling frame 3, the one-way synchronization 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 fall-resistant 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 mobile phone body 4 with the active bezel 301 held at the start of the stroke, so as to achieve the purpose of using it as a simple cradle;

referring to fig. 10, 11 and 13, based on the above arrangement of the unidirectional synchronization mechanism 18, the prior art has many embodiments, for example, the unidirectional synchronization mechanism 18 may be composed of an arc-shaped groove 181 and a convex pillar 182 which are slidably engaged, the arc-shaped groove 181 and the convex pillar 182 are respectively disposed on two opposite sides of the hinge joint of the active frame 301 and the passive frame 302, and the central axes of the arc-shaped groove 181 and the support 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. 10, generally speaking, the passive bezel 302 only needs to be located at the rear side of the mobile phone main body 4 in the fall-prevention mode and when being used as a simple support, and should be located at the beginning of the travel in most other times, for example, in the normal use process of the smart phone capable of preventing fall, the passive bezel 302 sometimes automatically separates from the beginning of the travel, which is bound to bring a certain trouble to the user. In the above anti-falling smart phone, in the initial mode, the two anti-falling legs 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 beginning of the stroke, and the passive frame 302 will not automatically separate from the beginning of the stroke; meanwhile, in order to improve the positioning effect of the falling-prevention feet 2 on the passive frame 302, the passive frame 302 and the corresponding two falling-prevention feet 2 can be further improved:

as shown in fig. 14, 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 restrained 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 anti-falling 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 synchronously rotate along with the active frame 301; in addition, the passive frame 302 can be manually driven to be separated from the positioning function of the falling-preventing leg 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.

In addition, as shown in fig. 12, 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. 12, in the anti-falling smart phone disclosed in embodiment 2, when the passive frame 302 is used as a simple support, the two corresponding anti-falling legs 2 extend to the outside of the host main body, although this phenomenon does not substantially affect the using effect of the anti-falling smart phone, the appearance of the anti-falling smart phone in this state is not acceptable to the public. Therefore, the present embodiment further improves the structure of the anti-falling smart phone disclosed in embodiment 2 to overcome the foregoing disadvantages, and the adopted improved structure is as follows:

referring to fig. 15 and 16, a pawl 21 is respectively arranged at the inner parts of the two placing seats 8 corresponding to the passive frame 302 in the mobile phone body 4, and a non-return groove 23 is respectively arranged on the two corresponding anti-falling legs 2; the two pawls 21 are respectively connected with the adjacent supporting shafts 1 through a pull wire 22, and the two supporting shafts 1 and the active frame 301 cannot rotate relatively; when the active frame 301 is at the initial position, the pull wire 22 does not pull the pawl 21, and after the anti-falling foot 2 moves to the stroke starting end, the pawl 21 automatically falls into the check groove 23 to prevent the anti-falling foot 2 from moving towards the stroke terminal direction; when the active frame 301 rotates from the beginning of the stroke to the end of the stroke, the pawls 21 are pulled by the tension lines 22 and cannot be matched with the non-return grooves 23, and then the two pawls 21 no longer hinder the movement of the corresponding two anti-falling legs 2.

Therefore, as shown in fig. 15, 16 and 17, when the anti-falling smart phone rotates the passive frame 302 to the rear side of the phone main body 4 to serve as a simple support in the initial mode, because 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 respective beginning of the stroke under the action of the pawl 21 and the check groove 23 and do not extend to the outside of the phone main body 4, so as to ensure that the shape of the anti-falling smart phone in this state conforms to the mass aesthetics; when the anti-falling smart phone is switched from the initial mode to the anti-falling mode, the active frame 301 and the passive frame 302 rotate from the starting end of the stroke to the ending end of the stroke, the two support shafts 1 pull the two pawls 21 to separate from the two check grooves 23 through the pull wires 22, and then the locking effect on the corresponding anti-falling legs 2 is released, so that the two anti-falling legs 2 corresponding to the passive frame 302 can be ensured to move to the ending end of the stroke.

Example 4

Referring to fig. 10 and 14, in the embodiment of the drop-resistant smart phone disclosed in example 2, it is mentioned that, in the initial mode of the drop-resistant smart phone, the passive bezel 302 may provide a certain positioning function by the drop-resistant 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-resistant foot 2 and the passive bezel 302 is also disclosed. For example, because the anti-falling foot 2 provides a certain positioning function when the passive frame 302 is located at the beginning of the stroke, when the anti-falling smart phone capable of preventing falling is switched from the initial mode to the anti-falling mode, a larger driving force needs to be provided for the passive frame 302 to overcome the positioning function, so that the requirement on the elasticity of the elastic component is obviously improved, meanwhile, the requirements on the strength of the support shaft 1, the active frame 301, the passive frame 302, the mobile phone main body 4, the electric locking mechanism 7 and other related components are also improved, and the performance is generally improved by increasing the size of the components, so that the components are not compact; in addition, this can prevent that smart mobile phone that falls prevents falling function is based on circulated use and designs, can manual reduction to initial mode under preventing falling the mode, after improving back shaft 1 department elastomeric element elasticity for the smart mobile phone that can prevent falling is no longer simple and convenient by preventing the manual operation that falls the mode and restore to initial mode. Therefore, the present embodiment is further improved based on the structure of the drop-resistant smart phone disclosed in embodiment 2 to overcome the above-mentioned shortcomings. The adopted specific scheme is as follows:

referring to fig. 18 and 19, 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 border 302 at the beginning 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 T2 is equal to T1, the micro-electromagnet 26 is energized briefly, and at this point, the micro-electromagnet 26 generates a magnetic field instantaneously to drive the magnetic sheet 25 to be separated from the iron sheet 24, that is, the passive border 302 is driven to rotate towards the 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 anti-falling smart phone adopts the structure, the anti-falling 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 to prevent the passive frame 302 from automatically separating from the stroke starting end; when the anti-falling smart phone 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 rather 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.
