At present, in order to achieve better use experience, a display screen is getting larger and larger, so that the size of the electronic equipment is correspondingly increased, and the problem of inconvenience in carrying and storing is brought. The appearance of the flexible folding screen meets the requirement of pursuing a portable large screen for consumers, taking a folding mobile phone as an example, the folding mobile phone with the folding screen has the same size as a conventional mobile phone after being folded, can be conveniently carried, and can obtain a screen with a larger display area when the screen is unfolded.

The existing folding mobile phone is divided into an inward folding type and an outward folding type, the two forms have respective advantages and disadvantages, and if the folding mobile phone can be folded inwards and outwards, the existing disadvantages can be solved and a plurality of new functions can be realized; however, when the foldable mobile phone is folded inwards, the back of the bending part needs to be provided with a part for protecting the screen body, when the foldable mobile phone is folded outwards, the back of the bending part cannot be provided with any part, and the two states have conflicting places, so that the foldable mobile phone is difficult to fold inwards and outwards.

In view of the above problems, embodiments of the present invention provide a supporting device and a display device, so that the display device can be folded inward and outward.

Referring to fig. 1 and 2 together, fig. 1 is a front view of a supporting device according to an embodiment of the present invention; fig. 2 shows a side view of a support device provided by an embodiment of the present invention.

The supporting device 100 provided by the embodiment of the invention is used for supporting the flexible display panel 200, and the supporting device 100 comprises a fixing component 10, a supporting component 20, a magnetic component 30 and a driving component 40.

The fixing assembly 10 comprises two fixing frames 11 which are connected in a relatively rotating manner. The supporting component 20 is disposed at a rotational joint of the two fixing frames 11, the supporting component 20 includes two supporting members 21, one of the two supporting members 21 is telescopically connected to one of the two fixing frames 11, and the other one is telescopically connected to the other one of the two fixing frames 11. The magnetic assembly 30 includes a first magnetic member 31 and a second magnetic member 32 interacting with each other, the first magnetic member 31 is disposed on the fixing frame 11 and the supporting member 21 having a retractable connection relationship, the second magnetic member 32 is disposed on the supporting member 21, the first magnetic member 31 has a first magnetic portion and a second magnetic portion in an extending direction thereof, and magnetism of the first magnetic portion is the same as that of the second magnetic member 32. The driving assembly 40 is disposed on the fixing frame 11, and the driving assembly 40 can drive the first magnetic member 31 to rotate until the first magnetic portion or the second magnetic portion faces the second magnetic member 32, so that the supporting member 21 extends out of or retracts into the fixing frame 11.

It is understood that the first and second magnetic parts of the first magnetic member 31 are magnetically different. The magnetism of the first magnetic part is the same as that of the second magnetic member 32, and the magnetism of the second magnetic part is different from that of the second magnetic member 32.

In the supporting device 100 provided by the embodiment of the present invention, under the driving of the driving assembly 40, when the first magnetic member 31 rotates until the first magnetic portion faces the second magnetic member 32, since the magnetism of the first magnetic portion is the same as that of the second magnetic member 32, the first magnetic member 31 and the second magnetic member 32 repel each other, and the repulsive force pushes the second magnetic member 32 to be away from the first magnetic member 31, so that the supporting member 21 extends out of the fixing frame 11; when the first magnetic member 31 rotates to make the second magnetic portion face the second magnetic member 32, the first magnetic member 31 and the second magnetic member 32 attract each other, and the attraction pulls the second magnetic member 32 to approach the first magnetic member 31, so that the supporting member 21 retracts into the fixing frame 11. Therefore, when the two fixing frames 11 rotate relatively, the supporting member 21 can extend out of the fixing frame 11 to shield the rotating connection position of the two fixing frames 11, and can also retract into the fixing frame 11 to make room for the rotating connection position of the two fixing frames 11.

It should be noted that the driving assembly 40 can drive the first magnetic member 31 to rotate, and the driving assembly 40 can also drive the first magnetic member 31 to rotate until the first magnetic member 31 is parallel to the second magnetic member 32, and specifically, the rotating position of the first magnetic member 31 can be selected according to the use requirement, which is not limited in this application.

In some alternative embodiments, the supporting device 100 provided by the embodiments of the present invention may further include a rotating connection assembly 50, and the fixing frame 11 is rotatably connected to the rotating connection assembly 50, so as to realize the relative rotating connection between the two fixing frames 11.

Alternatively, the two fixing frames 11 may be both rotatably connected to the rotating connection assembly 50, and the two fixing frames 11 may be spaced apart from each other in the width direction (X direction in the drawing) of the two fixing frames 11, so that the rotation centers of the two fixing frames 11 are different, and the two fixing frames 11 can rotate 360 ° relatively without interference.

As an alternative embodiment, the rotating connecting assembly 50 may include two end plates 51 and a fixing rod 52 connecting the two end plates 51, the two end plates 51 may be spaced apart in a length direction (Y direction in the drawing) of the fixing frame 11, and the fixing rod 52 may extend in the length direction of the fixing frame 11.

Alternatively, the rotating connection assembly 50 may include two fixing rods 52, and the two fixing rods 52 are spaced apart and connected to both ends of the end plate 51 in the width direction of the fixing frame 11. Of course, the rotating connection assembly 50 may include only one fixing rod 52, and the fixing rod 52 is connected to the end plate 51 at a middle position such that the fixing rod 52 is located between the two supporting members 21.

In the supporting device 100 provided in the embodiments of the present invention, there are various ways to drive the first magnetic member 31 to rotate to a desired position, and in some alternative embodiments, the driving assembly 40 may select a rotary driver having an autonomous driving function, such as a motor, and when in use, the rotary driver is controlled to drive the first magnetic member 31 to rotate to a corresponding position.

Certainly, the manner of driving the first magnetic member 31 to rotate to the desired position is not limited thereto, in some alternative embodiments, the driving assembly 40 may also be used as a transmission portion, when the fixed frame 11 rotates by using the first pin as a rotating shaft, the fixed frame 11 drives the first magnetic member 31 to rotate through the driving assembly 40, the rotation of the fixed frame 11 is used to provide power for the rotation of the first magnetic member 31, and the rotation position of the first magnetic member 31 is controlled by using the rotation position of the fixed frame 11, so that a power driver and a controller are not required to be additionally arranged, and the use is simpler and more convenient.

In some alternative embodiments, the driving assembly 40 may include a sliding member 41, a push rod 42 and a gear assembly 43, the sliding member 41 is slidably and movably connected with the fixed frame 11 and rotatably connected with the rotating connection assembly 50, a rotation center of the sliding member 41 is different from a rotation center of the fixed frame 11, the gear assembly 43 is disposed on the fixed frame 11 and connected to the sliding member 41 through the push rod 42, when the two fixed frames 11 rotate relatively, a relative displacement in a thickness direction (Z direction in the drawing) of the fixed frame 11 is generated between the sliding member 41 and the fixed frame 11, and the push rod 42 drives the first magnetic member 31 to rotate through the gear assembly 43.

It can be understood that, since the rotation center of the sliding member 41 is different from the rotation center of the fixed frame 11, and the sliding member 41 is slidably connected with the fixed frame 11, when the fixed frame 11 rotates, a relative displacement occurs between the sliding member 41 and the fixed frame 11.

It will be appreciated that the gear assembly 43 is capable of converting displacement of the push rod 42 in the thickness direction of the fixing frame 11 into rotation of the first magnetic member 31. The relative rotation directions of the two fixing frames 11 are different, and the displacement directions of the sliding part 41 and the push rod 42 relative to the fixing frame 11 are different, so that the gear assembly 43 can drive the first magnetic part 31 to rotate in different directions. In order to rotate the first magnetic member 31 to a desired position, the connection position of the push rod 42 and the sliding member 41 may be far away from the rotation connection position of the sliding member 41 and the rotation connection assembly 50.

As an alternative embodiment, a guide groove may be provided on the fixing frame 11, the sliding member 41 is provided with a guide rod 411, the guide rod 411 is inserted into the guide groove 12, so that the sliding member 41 is slidably connected with the fixing frame 11, when the fixing frame 11 rotates, the guide rod 411 slides along the guide groove 12 and rotates the sliding member 41 around its own rotation center. Alternatively, the guide groove 12 may be located on a plane perpendicular to the length direction of the fixing frame 11, and the guide bar 411 may extend in the length direction of the fixing frame 11.

Alternatively, the shape and position of the guide groove 12 may be set according to the movement trace of the guide rod 411 relative to the fixed frame 11 when the slider 41 rotates. As an alternative embodiment, when the sliding member 41 and the fixing frame 11 rotate around the respective rotation centers at the same angular speed, the movement track of the guide rod 411 relative to the fixing frame 11 can be set to the shape and position of the guide groove 12 on the fixing frame 11. It can be understood that the relative positions of the rotation center of the sliding member 41 and the rotation center of the fixing frame 11 are different, and the motion track of the guide rod 411 relative to the fixing frame 11 is different.

As an alternative embodiment, in order to increase the relative rotation range of the two fixing frames 11, the guide slot 12 may include a first sliding slot 121 and a second sliding slot 122 connected at a predetermined angle and communicated with each other, and when the two fixing frames 11 rotate relatively, the guide rod 411 can slide from one end of the first sliding slot 121 opposite to the connection of the second sliding slot 122 to one end of the second sliding slot 122 opposite to the connection of the first sliding slot 121.

It should be noted that the relative positions of the rotation center of the sliding member 41 and the rotation center of the fixed frame 11 are not particularly limited in the present application. As an alternative embodiment, the rotation center of the sliding member 41 may be disposed between the rotation center of the fixed frame 11 and the guide bar 411, in which case the opening of the guide groove 12 faces the rotation center side of the fixed frame 11. Of course, it is also possible to arrange the rotation center of the sliding component 41 on the side of the rotation center of the fixing frame 11 away from the guide rod 411, and it is within the scope of the present application that the opening of the guiding groove 12 is away from the side of the rotation center of the fixing frame 11.

It will be understood that the support device 100 has a first folded state, in which the angle between the two holders 11 is less than 180 °, an unfolded state, in which the angle between the two holders 11 is 180 °, and a second folded state, in which the angle between the two holders 11 is greater than 180 °.

Optionally, in the unfolded state of the supporting device 100, the guide rod 411 is located at a connection portion of the first sliding slot 121 and the second sliding slot 122, in the first folded state of the supporting device 100, the guide rod 411 is located at an end of the first sliding slot 121 away from the second sliding slot 122, and in the second folded state of the fixing assembly 10, the guide rod 411 is located at an end of the second sliding slot 122 away from the first sliding slot 121.

Of course, the relative rotation angle range of the two fixing frames 11 is not limited to this, and can be adjusted according to actual needs.

Referring to fig. 3, fig. 3 is a schematic structural diagram illustrating a gear assembly of the supporting device according to an embodiment of the present invention.

In some optional embodiments, in the supporting device 100 provided in the embodiments of the present invention, the first magnetic member 31 may be rotatably connected to the fixed frame 11, the gear assembly 43 may include a bevel gear 431, a first gear 432, and a second gear 433, the second gear 433 is coaxially disposed and fixedly connected to the first magnetic member 31, the first gear 432 is rotatably connected to the fixed frame 11, the first gear 432 is in straight-tooth engagement with the second gear 433, the bevel gear 431 is in straight-tooth engagement with the first gear 432, and one end of the push rod 42 away from the sliding member 41 is eccentrically and fixedly connected to the bevel gear 431, and when the push rod 42 moves up and down along with the sliding member 41 in the thickness direction of the fixed frame 11, the bevel gear 431 is driven to rotate counterclockwise or clockwise, so as to drive the first magnetic member 31 to rotate in different directions.

Alternatively, the push rod 42 may extend in the width direction of the fixed frame 11, the gear shaft of the bevel gear 431 may be perpendicular to the push rod 42 and parallel to the length direction of the fixed frame 11, and the gear shafts of the first gear 432 and the second gear 433 and the rotation shaft of the first magnetic member 31 may be perpendicular to the length direction and the width direction of the fixed frame 11, so that the first magnetic member 31 can rotate until the first magnetic portion or the second magnetic portion thereof faces the second magnetic member 32 when rotating around the shaft.

The operation principle of the supporting device 100 will be described with reference to a part a in fig. 1, in which the first magnetic part of the first magnetic member 31 is an S-pole, the second magnetic part is an N-pole, and the magnetic part of the second magnetic member 32 is an S-pole. Referring to fig. 4 to 6, fig. 4a is a partial side view of a support device in an unfolded state according to an embodiment of the present invention; FIG. 4b illustrates a partial front view of a support device in an expanded state according to one embodiment of the present invention; FIG. 5a illustrates a partial side view of a support device provided in accordance with an embodiment of the present invention in a first, collapsed state; FIG. 5b illustrates a partial front view of a support device provided in accordance with an embodiment of the present invention in a first, collapsed state; FIG. 6a illustrates a partial side view of a support device in a second, folded state according to an embodiment of the present invention; fig. 6b shows a partial front view of a support device according to an embodiment of the present invention in a second folded state.
