The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Referring to fig. 1-9, an embodiment of the present invention provides a flexible device, which includes a connecting plate 104, a first rotating joint 101, a second rotating joint 103, a middle rotating joint 102, and a fixing mechanism; the connecting plate 104 can be bent into an arc shape, the first rotating joint 101 is fixed on the connecting plate 104, the second rotating joint 103 is fixed on the connecting plate 104, the middle rotating joint 102 is fixed on the connecting plate 104, and the first rotating joint 101, the middle rotating joint 102 and the second rotating joint 103 are sequentially arranged on the connecting plate 104; the fixing mechanism is connected with each rotary joint; wherein the connecting plate 104 is located on a first side of each revolute joint; the flexible device has a plurality of using states, and the fixing mechanism can keep the second side of each rotating joint at different furling degrees so as to keep the flexible device at each using state.

The fixing mechanism in the flexible device provided by the embodiment of the invention can keep the flexible device in various using states, and each rotating joint in the flexible device is respectively fixed on the connecting plate 104, so that the flexible device is simple in structure, and adjacent rotating joints are not directly connected, so that each rotating joint can be conveniently set into a regular shape, and the flexible device is convenient to produce and manufacture.

In the flexible device provided in the above embodiment, the fixing mechanism includes a sliding plate 107, a first end of the sliding plate 107 is fixedly connected to the first rotating joint 101, a second end of the sliding plate 107 is slidably disposed on the second rotating joint 103, and the sliding plate 107 is slidably connected to the intermediate rotating joint 102 with respect to the intermediate rotating joint 102; when the using state of the flexible device is switched, the folding degree of the second side of each rotating joint is changed, the second end of the sliding sheet 107 slides along the second rotating joint 103, and the sliding sheet 107 limits the flexible device to change the using state along the preset track. In the flexible device, the sliding sheet 107 limits the flexible device to change the use state along the preset track, so that the flexible device can be prevented from extruding electronic elements of electronic equipment applying the flexible device due to deformation, and the electronic elements of the electronic equipment can be prevented from being damaged.

Specifically, in the flexible device, the sliding piece 107 is inserted into the middle rotational joint 102, or is clamped in a clamping groove on the surface of the middle rotational joint 102.

The second end of the slide 107 is held at a first predetermined position on the second revolute joint 103 when the flexible device is in the first use state, and the second end of the slide 107 is held at a second predetermined position on the second revolute joint 103 when the flexible device is in the second use state. In the flexible device provided by this embodiment, the sliding piece 107 is kept at the preset position on the second rotating joint 103, so that the second side of the rotating joint is kept at the preset furling degree, and thus the flexible device is maintained in each use state, and the reliability of the flexible device is improved.

Specifically, in the flexible device provided in the above embodiment, the fixing mechanism is configured to include a clamping member 106 engaged with the second end of the sliding piece 107, and correspondingly, a sliding slot engaged with the clamping member 106 is provided on the second rotational joint 103, during the process of switching the use state of the flexible device, the clamping member 106 slides along the sliding slot, and when the flexible device is in different use states, the clamping member 106 is kept at the preset position in the sliding slot, so that the second end of the sliding piece 107 is kept at the preset position on the second rotational joint 103. The flexible device provided by the embodiment is provided with the clamping piece 106 and the sliding groove which are matched with each other, so that the second end of the sliding piece 107 is prevented from being directly connected to the preset position on the second rotating joint 103 in different use states, and the flexible device is convenient to switch the use states and is kept in each use state.

Preferably, in the above embodiment, the clamping member 106 and the second end of the sliding piece 107 keep moving synchronously along the first direction, which is the sliding direction of the second end of the sliding piece 107 along the second rotating joint 103.

In order to keep the second end of the slide 107 at different predetermined positions on the second revolute joint 103 in different use states, the above embodiment provides a flexible device in which the slide groove is arranged to include at least 3 points, wherein the first point, the second point and the third point are arranged in sequence along the slide groove, the first point of the 3 points being closest to the intermediate revolute joint 102 and the second point being furthest from the intermediate revolute joint 102; when the flexible device is switched from the first use state to the second use state, the flexible device is driven by external force to deform, the clamping piece 106 slides to the second point from the first point along the sliding groove, the external force disappears, and the clamping piece 106 slides to the third point along the sliding groove and is kept at the third point. Obviously, in the process of switching the flexible device from the first use state to the second use state, the joint 106 firstly keeps away from the middle rotating joint 102 along the chute section from the first point to the second point, and then is close to the middle rotating joint 102 along the chute section from the second point to the third point, and the whole stroke is in a bending shape of keeping away from and then being close to, so that the joint 106 can be prevented from sliding back to the first point along the chute from the second point by the third point when not driven by external force, and the flexible device can be ensured to be kept in the second use state, and the reliability is high.

Further, when the flexible device provided by the above embodiment is switched from the second use state to the first use state, the clamping member 106 may slide to the second point under the action of the external force, and then slide to the first point from the second point along the sliding groove and keep at the first point after the external force disappears; preferably, when the flexible device is switched from the second state to the first state, the engaging member 106 slides from the other sliding groove to the first point, as shown in fig. 7-8, the following description specifically refers to the case where the flexible device has only two states of use, and the flexible device slides along the different sliding grooves when switching between the two states of use:

the sliding groove is arranged to comprise a first sliding groove and a second sliding groove, the first sliding groove comprises an AB section and a BC section, the second sliding groove comprises a CD section and a DA section, and a point B and a point D are respectively farther away from the middle rotating joint 102 than a point C; when the flexible device is switched from the first use state to the second use state, the clamping piece 106 slides to a point C from a point A along the AB section and the BC section and is kept at the point C; when the flexible device is switched from the second use state to the first use state, the clamping piece 106 slides to the point A along the CD section and the DA section and is kept at the point A.

Further, in order to avoid the locking of the snap-in member 106 at each turning point on the sliding chute or the reverse sliding along the sliding chute, in the flexible device provided in the above embodiment, the groove bottom at the starting position of the AB section of the sliding chute is lower than the groove bottom at the ending position of the DA section, and the groove bottom at the ending position of the AB section of the sliding chute is higher than the groove bottom at the starting position of the BC section; the groove bottom at the starting position of the CD section is lower than the groove bottom at the ending position of the BC section, and the groove bottom at the ending position of the CD section is higher than the groove bottom at the starting position of the DA section. The design of tank bottom in this scheme makes joint spare 106 slide along the direction of predetermineeing at the spout, ensures that flexible device is smooth and easy to be out of shape in the switching process of user state.

Correspondingly, the flexible device provided by the above embodiment may further be set to have three use states, the bending degree of the flexible device is different in the three use states, the corresponding sliding groove needs to be set to have a bending section which is respectively corresponding to the flexible device and is switched between the first use state and the second use state, and the switching between the second use state and the third use state is not repeated in this embodiment.

In the process of switching the use states of the flexible device provided in the above embodiment, the flexible device needs to be deformed to a larger degree by external force, and then deformed to a straight direction by the rigidity of the connecting plate 104 after the external force disappears, and the engaging member 106 is finally held at the preset position of the chute, but the rigidity of the connecting plate 104 after long-term use is deteriorated, and it is difficult to keep the engaging member 106 at a position corresponding to each use state, so the fixing mechanism further includes a driving member that connects the second end of the sliding piece 107 and the intermediate rotating joint 102 adjacent to the second rotating joint 103, and the driving member applies a force to the second end of the sliding piece 107 to move to the intermediate rotating joint 102.

When the state of the flexible device is switched, the external force overcomes the acting force of the driving piece firstly to drive the flexible device to deform in the direction with larger bending degree, so that the clamping piece 106 moves to the bending part of the sliding groove along the sliding groove in the direction away from the middle rotating joint 102, the external force disappears afterwards, the second end of the sliding piece 107 moves in the direction close to the middle rotating joint 102 along the sliding groove under the action of the driving piece until the clamping piece 106 slides to the preset position along the sliding groove. Obviously, when the flexible device is driven to switch the use state, a user only needs to increase the bending degree of the flexible device, and the operation of the user is facilitated.

Specifically, the driving member may be an elastic member, and may also be two magnets 109 fixedly connected to the second end of the sliding piece 107 and the intermediate revolute joint 102 adjacent to the second revolute joint 103, respectively, and capable of attracting each other.

Because the chute is the state of buckling, in the process that the sliding piece 107 slides along the second revolute joint 103, the end of the clamping piece 106 not only needs to move along the first direction, but also needs to move along the direction perpendicular to the first direction, so in order to ensure that the clamping piece 106 can slide along the chute, in the flexible device provided by the above embodiment, the second end of the sliding piece 107 is provided with the first guide block 108 capable of sliding along the second direction, and the clamping piece 106 is provided with the pin fixed on the first guide block 108.

Specifically, in the flexible device provided in the above embodiment, the second end of the sliding piece 107 is fixed with the second guide block 105, the second guide block 105 is slidably clamped in the second rotating joint 103, for the convenience of assembly, the first guide block 108 is disposed on the second guide block 105, and the driving element is fixedly connected with the second end of the sliding piece 107 through the second guide block 105.

Of course, in order to simplify the structure, the snap-in member 106 in the flexible device may also be a snap hook rotatably disposed at the second end of the sliding plate 107, and the structure of the snap-in member 106 and the connection manner with the second end of the sliding plate 107 are not limited in this embodiment, and it is only necessary to ensure that the snap hook can slide along the sliding groove.

The flexible device at least comprises a first bending use state and a straight use state in a plurality of use states so as to meet the practical use requirement of the flexible electronic equipment. When the flexible device is in a flat use position, the slide 107 is flat and parallel to the connection plate 104.

The embodiment of the invention also provides electronic equipment which comprises a flexible screen and a flexible device for supporting the flexible screen, wherein the flexible device is the flexible device provided by the embodiment.

The electronic equipment provided by the invention adopts the flexible device, can be kept in various using states, and has the advantages of simple structure and convenient component preparation. Of course, the electronic device provided in the embodiment of the present invention also has other effects related to the flexible device provided in the above embodiments, and details are not described herein again.
