By providing two support bars 03 in the display device, the stability of the support bar 03 supporting the display device can be ensured.

The rotation joint of the first system module 012 and the second system module 013 in the first display screen assembly 01 is provided with a second angle fixing assembly, which can be used to fix the angle between the first system module 012 and the second system module 013. The rotating joint of the support rod 03 and the first display screen assembly 01 is provided with a third angle fixing assembly, and the third angle fixing assembly can be used for fixing the angle between the support rod 03 and the first display screen assembly 01.

In the embodiment of the application, two structures rotatably connected in the display device can be connected through the shaft sleeve and the rotating shaft, and the rotating shaft can be a hollow rotating shaft. Fig. 7 is a schematic structural diagram of an angle fixing assembly according to an embodiment of the present disclosure. As can be seen with reference to fig. 7, each angle fixing assembly may include: an extension rod 0151 arranged in the hollow rotating shaft, a slide block 0152, a first elastic component 0153 and a clamping block 0154.

One end of the extension rod 0151 can abut against the slide block 0152, and the extension rod 0151 can be used for pushing the slide block 0152 to move along the axial direction of the hollow rotating shaft. The first elastic component 0153 may be disposed on a side of the sliding block 0152 away from the extension rod 0151, and a stretching direction of the first elastic component 0153 may be parallel to an axial direction of the hollow rotating shaft. The side of the sliding block 0152 facing away from the first elastic component 0153 can be a slope, and the thickness of the sliding block 0152 in the direction perpendicular to the stretching direction of the first elastic component 0153 gradually decreases in the direction away from the first elastic component 0153. The side wall of the hollow rotating shaft is provided with a slot, and the axial direction of the slot can intersect with the telescopic direction of the first elastic component 0153. The other end of the latch 0154 may contact a surface of the slider 0152 facing away from the first elastic member 0153. The surface of the sliding block 0152 facing away from the first elastic component 0153 may refer to the surface of the sliding block 0152 close to the clamping block 0154.

FIG. 8 is a cross-sectional view of the angle fixing assembly shown in FIG. 7. Referring to fig. 8, a plurality of block grooves a may be formed in an inner wall of the shaft sleeve, and may be arranged along a circumferential direction of the shaft sleeve, and each block groove a may be configured to clamp one end of the clamping block 0154.

Optionally, the inner wall of the shaft sleeve is uniformly provided with 3 clamping block grooves a along the circumferential direction of the shaft sleeve. Or, 3 block grooves a arranged on the inner wall of the shaft sleeve along the circumferential direction of the shaft sleeve can be non-uniformly arranged. Or, 2 or more clamping block grooves a may be formed in the inner wall of the shaft sleeve along the circumferential direction of the shaft sleeve, which is not limited in the embodiment of the present application.

When one end of the latch 0154 is latched in a latch groove a formed in the inner wall of the shaft sleeve, a user can press the other end of the extension rod 0151, so that the extension rod 0151 can push the slider 0152 to move towards the direction close to the first elastic component 0153 along the axial direction of the hollow rotating shaft, and at the moment, the first elastic component 0153 can be compressed. Since the thickness of the slider 0152 in the direction perpendicular to the stretching direction of the first elastic component 0153 is gradually reduced in the direction away from the first elastic component 0153, the thickness of the slider 0152 is reduced at the orthographic projection of the latch 0154 on the slider 0152 after the slider 0152 moves to the direction approaching the first elastic component 0153. The latch 0154 can move along the axial direction of the slot to a direction far away from the latch groove a, so that the latch 0154 is separated from one latch groove a arranged on the inner wall of the shaft sleeve.

Then, the user can rotate the shaft sleeve to make the position of another block groove a arranged on the inner wall of the shaft sleeve correspond to the position of the block 0154. At this time, the user stops pressing the other end of the extension rod 0151, the first elastic component 0153 pushes the slider 0152 to move away from the first elastic component 0153 under the action of its own elastic force, and the thickness of the slider 0152 is increased at the orthographic projection of the fixture block 0154 on the slider 0152. The latch 0154 can move in a direction approaching to the other latch groove a by the pushing of the slider 0152, so that the latch 0154 is latched in the other latch groove a arranged on the inner wall of the sleeve 014.

As can also be seen with reference to fig. 7 and 8, each angle fixing assembly may further include: a second resilient component 0155. One end of the second elastic component 0155 can be fixedly connected with the inner wall of the hollow rotating shaft, the other end of the second spring can be clamped with the clamping block 0154, and the telescopic direction of the second elastic component 0155 can be perpendicular to that of the first elastic component 0153.

When one end of the latch 0154 is latched in one latch groove a, the second elastic component 0155 can be in a compressed state. When the sliding block 0152 moves towards the direction approaching to the first elastic component 0153, because the thickness of the sliding block 0152 is reduced at the orthographic projection of the fixture block 0154 on the sliding block 0152, the fixture block 0154 can move towards the direction away from the fixture block groove a under the action of the elastic force of the second elastic component 0155, so that the fixture block 0154 can be separated from one fixture block groove a.

Alternatively, first resilient assembly 0153 and second resilient assembly 0155 may each include one or more springs.

Referring to fig. 7, each angle fixing assembly may further include: a baffle 0156. One surface of the baffle 0156 can be fixedly connected with one end of the extension rod 0151, and the other surface of the baffle 0156 can be abutted with the slide block 0152. The baffle 0156 may be disposed in the hollow shaft sleeve, and a side wall of the baffle 0156 may contact an inner wall of the hollow shaft sleeve, and the baffle 0156 may be capable of moving in a telescopic direction of the first elastic member 0153. By providing the baffle 0156, the reliability of the movement of the extension rod 0151 pushing the slider 0152 can be improved.

As can be seen with reference to fig. 8, the latch 0154 may include: a snap-in portion 01541 and a moving portion 01542. The clamping portion 01541 can be clamped in a slot provided on the side wall of the hollow rotating shaft, and the moving portion 01542 can move towards or away from the block slot a under the action of the slider 0152. The orthographic projection of the clamping portion 01541 on the moving portion 01542 is located within the moving portion 01542. The other end of the second elastic component 0155 can be clamped with one surface of the moving part 01542 close to the clamping part 01541.

The shape of the cross section of the clamping portion 01541 can be the same as the shape of the slot and the shape of the fixture block slot a, and the clamping portion 01541 is in clearance fit with the slot and the fixture block slot a. For example, if the shape of the slot and the shape of the latch groove a are circular, the cross-sectional shape of the latching portion 01541 may be circular, and if the shape of the slot and the shape of the latch groove a are square, the cross-sectional shape of the latching portion 01541 may be square. Certainly, the cross section of the clamping portion 01541 can also be in other shapes, which is not limited in the embodiment of the present application, and it is only required to ensure that the clamping portion 01541 can be effectively clamped in the block groove a.

As can be seen from fig. 7 and 8, the side of the moving portion 01542 away from the clamping portion 01541 may be an inclined surface, and the thickness of the moving portion 01542 in the stretching direction of the first elastic member 0153 gradually decreases in the direction away from the clamping portion 01541. Therefore, the surface of the moving part 01542 far from the clamping part 01541 and the surface of the sliding block 0152 far from the first elastic component 0153 can be in surface contact, and the stability of the angle fixing component in angle fixing is ensured.

On the one hand, for the first system module 012 and the second system module 013, the first hollow cylinder 0141 and the second hollow cylinder 0142 of the shaft sleeve 014 are respectively sleeved on the first rotating shaft 0121 and the second rotating shaft 0131 to realize the rotation connection, the first rotating shaft 0121 and the second rotating shaft 0131 may both be hollow rotating shafts, and the angle fixing components as described in the above embodiments may be disposed in the first rotating shaft 0121 and the second rotating shaft 0131, so as to fix the included angle between the first system module 012 and the second system module 013.

On the other hand, to the scheme that the support rod 03 and the first display screen assembly 01 are rotatably connected through the through hole formed in the support rod 03 and the third rotating shaft 0122 formed in the first display screen assembly 01, the third rotating shaft 0122 may be a hollow rotating shaft, and the angle fixing assembly according to the above embodiment may be disposed in the third rotating shaft 0122, so as to fix the included angle between the support rod 03 and the first display screen assembly 01.

In another aspect, the other end of the first system module 012 in the first display screen assembly 01 may be provided with a through hole, and one end of the second display screen assembly 02 is provided with a fourth rotation shaft. To first display screen subassembly 01 and second display screen subassembly 02 through setting up the through-hole on the other end of first system module 012 to and the scheme of rotation connection is realized to the fourth pivot. The fourth rotating shaft can be a hollow rotating shaft, and the angle fixing component in the embodiment can be arranged in the fourth rotating shaft, so that the included angle between the first display screen component 01 and the second display screen component is fixed. Or, the other end of the first system module 012 in the first display screen assembly 01 may be provided with a fifth rotating shaft, and one end of the second display screen assembly 02 is provided with a through hole. The scheme of rotationally connecting the first display screen component 01 and the second display screen component 02 through a through hole formed in one end of the second display screen component 02 and a fifth rotating shaft is achieved. The fifth rotating shaft can be a hollow rotating shaft, and the angle fixing component in the embodiment can be arranged in the fifth rotating shaft, so that the included angle between the first display screen component 01 and the second display screen component is fixed.

Referring to fig. 1, it can be seen that the axis of rotation of the second screen assembly 02 with respect to the first screen assembly 01 may be parallel to the folding line of the first screen assembly 01. And when the included angle between the second display screen assembly 02 and the first display screen assembly 01 is 180 degrees, the display plane of the second display screen assembly 02 may be coplanar with the display plane of the first display screen assembly 01. That is, the display plane of the first display module 01 and the display plane of the second display module 02 are located on the same plane of the display device.

The first display screen assembly 01 can be folded towards a direction close to the display plane of the first display screen assembly 01, and the folding angle range of the first display screen assembly 01 is 0 degree to 180 degrees. The upper limit of the range of the angle of rotation of the second screen assembly 02 with respect to the back surface of the first screen assembly 01 is greater than 180 degrees and less than 360 degrees. For example, the upper limit value of the angle range in which the second screen assembly 02 is rotated with respect to the rear surface of the first screen assembly 01 is 270 degrees. The back surface of the first display screen assembly 01 may be a surface of the first display screen assembly 01 opposite to the display plane of the first display screen assembly 01.

In the embodiment of the present application, the axis of rotation of the second display screen assembly 02 with respect to the first display screen assembly 01 may also be perpendicular to the folding line of the first display screen assembly 01. The embodiment of the present application does not limit the relative position of the axis of rotation of the second display screen assembly 02 with respect to the first display screen assembly 01 and the folding line of the first display screen assembly 01.

Fig. 9 is a schematic structural diagram of another display device according to an embodiment of the present application. Referring to fig. 9, it can be seen that when the folding angle of the first display screen assembly 01 is 0 degree and the angle of rotation of the second display screen assembly 02 with respect to the back surface of the first display screen assembly 01 is 0 degree, that is, when the display device is in the folded state, the display plane of the first display screen assembly 01 is located inside and the display plane of the second display screen assembly 02 is located outside. Therefore, when the display device is in a folded state, a user can process time-efficient information such as a telephone call and a short message through the second display screen assembly 02. The user does not need to look over the first display assembly after unfolding, and the efficiency is high. Illustratively, the display plane of the second display component 02 in fig. 9 is displayed with a clock icon and time "08: 27".

In the embodiment of the present application, the first display panel assembly 01 may be an OLED display assembly, and the second display assembly 02 may be a liquid crystal display assembly. The OLED display screen included in the OLED display assembly 01 is generally made of a flexible material and is easily punctured by a sharp object. The liquid crystal display panel included in the liquid crystal display module 02 generally has a glass Cover (CG) having a relatively hard surface and being less vulnerable to puncture by a sharp object. When display device is in fold condition, the display plane with the OLED display screen in OLED display module 01 is located inside, the display plane of the liquid crystal display screen in liquid crystal display module 02 is located the outside, on the one hand, the probability that the OLED display screen in OLED display module 01 is damaged can be reduced, on the other hand, the user can check information through the liquid crystal display screen in liquid crystal display module 02 conveniently, the user does not need to look over after OLED display module 01 is unfolded, the folding times of OLED display module 01 are reduced, and the service life of OLED display module 01 is prolonged.

Referring to fig. 9, when the display device is in a folded state, the orthographic projection of the second display screen assembly 02 on the first display screen assembly 01 can be located in an area where a housing of a system module in the first display screen assembly 01 is located. The length of the second display screen assembly 02 in the direction of the folding line X of the first display screen assembly 01 may be smaller than the length of the first display screen assembly 01 in the direction of the folding line of the first display screen assembly 01. Therefore, when the display device is in a folded state, the two support rods 03 rotatably connected with the first display screen assembly 01 have spaces respectively arranged on two sides of the second display screen assembly 02, and the occupied space of the display device is reduced.

It should be noted that, when the display device is in the unfolded state, the first display screen assembly 01 may serve as a main display assembly, and at this time, the second display screen assembly 02 may be in the closed state.
