The first housing 200 and the second housing 300 are electronic devices that can achieve relative folding and unfolding. part, so that the electronic device can be switched between the folded state and the unfolded state, and the first housing 200, the second housing 300 and the shaft assembly 100 form a support structure for the flexible screen 400, so that the flexible screen 400 can be set It is placed on a larger plane on the electronic device, so as to meet the user's demand for using a large screen.

The rotating shaft assembly 100 includes a rotating shaft 110, a first adjusting bracket 120 and a second adjusting bracket 130. The rotating shaft 110 is used as a connecting mechanism for electronic equipment. The first end of the bracket 120 is disposed in the first slide rail 100a and slidably matched with the first slide rail 100a, so that the first adjustment bracket 120 can slide in the first slide rail 100a, and the first end of the second adjustment bracket 130 The second adjusting bracket 130 can be slidably moved in the second sliding rail 100b by being disposed in the second sliding rail 100b and slidably matched with the second sliding rail 100b. The second end of the first adjusting bracket 120 is connected to the first housing 200 , and the second end of the second adjusting bracket 130 is connected to the second housing 300 . When the electronic device is switched between the folded state and the unfolded state, the first adjustment bracket 120 and the second adjustment bracket 130 relatively move relative to the rotating shaft 110 . The first casing 200 is also rotatably connected to the second casing 300 through the rotating shaft 110, so that the first casing 200 and the second casing 300 can realize the folded state and the unfolded state of the electronic device by moving relative to the rotating shaft 110.

In the above situation, the rotating shaft 110 can be rotatably connected to the first housing 200 and the second housing 300 through the first adjustment bracket 120 and the second adjustment bracket 130 respectively, so that the electronic device is connected to the first adjustment bracket 120 and the first The first casing 200 and the second casing 300 can be folded and unfolded in the sliding cooperation of the sliding rail 100a and the sliding cooperation between the second adjusting bracket 130 and the second sliding rail 100b.

Therefore, the flexible screen 400 can be prevented from being pulled during the folding and unfolding process of the electronic device. The technical solution adopted in the embodiments of the present application can undoubtedly solve the problem of the flexible screen 400 being folded outwards when the electronic device in the background technology is folded outward. The screen 400 is easily damaged by being pulled, resulting in a short lifespan of the electronic device.

At the same time, during the folding and unfolding process of the electronic device, since the first ends of the first adjustment bracket 120 and the second adjustment bracket 130 are slidably fitted in the first sliding rail 100a and the second sliding rail 100b, respectively, the first The adjusting bracket 120 and the second adjusting bracket 130 can relatively slide relatively easily in the first sliding rail 100a and the second sliding rail 100b, so that the second end of the first adjusting bracket 120 and the second end of the second adjusting bracket 130 Corresponding regions of the respectively connected flexible screens 400 move relative to each other, thereby facilitating the switching of the electronic device between the folded state and the unfolded state, thereby enabling the user to use the two states of the electronic device more smoothly, and ultimately improving the user experience. user experience.

In the electronic device disclosed in this embodiment of the present application, the shaft assembly 100 may further include a first connection bracket 140 and a second connection bracket 150 , and the first connection bracket 140 and the second connection bracket 150 are disposed at the ends of the rotation shaft 110 and are symmetrical The first connecting bracket 140 and the second connecting bracket 150 are both rotatably connected to the rotating shaft 110, and the first connecting bracket 140 is connected to the first casing 200, and the first casing 200 passes through the first casing 200.

In the above case, the first connection bracket 140 and the second connection bracket 150 are other structures in the auxiliary shaft assembly 100 to complete the two structures of switching the electronic device between the folded state and the unfolded state. During the process of folding and unfolding the electronic device, since the rotating shaft 110 is rotatably connected to the first casing 200 through the first connecting bracket 140, and the rotating shaft 110 is rotatably connected to the second casing 300 through the second connecting bracket 150, the first connection is made.

At the same time, since the first meshing teeth 141 and the second meshing teeth 151 can increase the damping between the first connecting bracket 140 and the second connecting bracket 150 through the gear structure, the first connecting bracket 140 and the second connecting bracket 150 can drive the first connecting bracket 140 and the second connecting bracket 150. The first housing 200 and the second housing 300 realize the hovering of the electronic device at various angles between the folded state and the unfolded state, thereby meeting the multi-angle usage requirements of the user when using the electronic device.

In this case, the first connecting brackets 140 are evenly distributed at both ends of the rotating shaft 110 , so that the first connecting rod 142 and the second connecting rod 143 can more stably support the first housing 200 at both ends of the rotating shaft 110 . Meanwhile, when the electronic device is switched between the folded state and the unfolded state, the first connecting rod 142 and the second connecting rod 143 at both ends of the rotating shaft 110 can drive the first housing 200 more stably.

The second connecting bracket 150 may include a third connecting rod 152 and a fourth connecting rod 153. The first end of the third connecting rod 152 and the first end of the fourth connecting rod 153 are hinged to the two ends of the rotating shaft 110, respectively. The third connecting rod The second end of the rod 152 and the second end of the fourth connecting rod 153 extend away from the rotating shaft 110 , and the first end of the third connecting rod 152 and the first end of the fourth connecting rod 153 are both provided with second meshing teeth 151 , the third connecting rod 152 and the fourth connecting rod 153 are respectively connected with both ends of the second housing 300 . In this case, the second connecting brackets 150 are evenly distributed on both ends of the rotating shaft 110 , so that the third connecting rod 152 and the fourth connecting rod 153 can more stably support the second housing 300 at both ends of the rotating shaft 110 Meanwhile, when the electronic device is switched between the folded state and the unfolded state, the third connecting rod 152 and the fourth connecting rod 153 at both ends of the rotating shaft 110 can drive the second housing 300 more stably.

At the same time, the first end of the first connecting rod 142, the first end of the second connecting rod 143, the first end of the third connecting rod 152 and the first end of the fourth connecting rod 153 are all provided with first meshing teeth 141 or the second meshing teeth 151, so that the first meshing teeth 141 at the first end of the first connecting rod 142 and the first end of the second connecting rod 143 can interact with the third The first end of the connecting rod 152 and the second meshing teeth 151 of the first end of the fourth connecting rod 153 are engaged with each other, so that the four kinds of connecting rods support the first housing 200 and the second housing 300 during the rotation process. , through the engagement of the first meshing teeth 141 and the second meshing teeth 151 , the first connecting brackets 140 and the second connecting brackets 150 at both ends of the rotating shaft 110 can ensure that the flexible screen 400 is more stably hovering at various angles.

In the electronic device disclosed in this embodiment of the present application, both the first adjustment bracket 120 and the second adjustment bracket 130 may include adjustment rods.

The rotating shaft 110 is provided with an assembly space, and the inner wall of the assembly space is provided with an arc-shaped groove. The first end of the adjustment rod penetrates into the assembly space, and the sliding protrusion 600 is slidingly matched with the arc groove. The inner wall of the assembly space is provided with a first limiting protrusion 112 and a second limiting protrusion 113. The first limiting protrusion 113 The protrusions 112 and the second limiting protrusions 113 are respectively disposed on both sides of the adjusting rod, and it can also be considered that they are respectively disposed on both sides of the first adjusting bracket 120 or the second adjusting bracket 130, and the first limiting protrusions 112 and The distance between the center line of the rotating shaft 110 is the first distance, the distance between the second limiting protrusion 113 and the center axis of the rotating shaft 110 is the second distance, and the first distance is not equal to the second distance.

In the above solution, since the sliding protrusion 600 is slidably matched with the arc-shaped groove, the movement of the adjusting rod provided with the sliding protrusion 600 is also limited by the movement range of the sliding protrusion 600, so that the sliding protrusion 600 and the The sliding fit of the arc-shaped grooves can limit the position of the first adjusting bracket 120 and the second adjusting bracket 130 . The first limiting protrusion 112 and the second limiting protrusion 113 provided on both sides of the adjusting rod restrict the position of the adjusting rod, so that when the sliding protrusion 600 of the adjusting rod is in the designated position in the arc groove, the adjustment The rotational position of the rod relative to the shaft 110 is also fixed.

At the same time, since the sliding protrusion 600 can be slidably fitted in the arc-shaped groove, the adjusting rod can use the first limiting protrusion 112 or the second limiting protrusion 113 as a fulcrum, thereby realizing the first adjusting bracket 120 The first end of the first adjustment bracket 120 or the first end of the second adjustment bracket 130 is better moved in the arc-shaped groove, and at the same time, the rotation of the first adjustment bracket 120 or the second adjustment bracket 130 is realized. Specifically, during the folding process, the first adjusting bracket 120 rotates with the first limiting protrusion 112 as the pivot point, while the first end of the first adjusting bracket 120 slides in the arc-shaped groove. During the unfolding process, the first adjusting bracket 120 rotates with the second limiting protrusion 113 as the pivot point, and at the same time, the first end of the second adjusting bracket 130 slides in the arc-shaped groove. Of course, the above situation is also applicable to the rotation of the second adjusting bracket 130 .

The first limiting protrusion 112 and the second limiting protrusion 113 are respectively disposed on both sides of the first adjustment bracket 120 or the second adjustment bracket 130, and can restrain the first adjustment bracket 120 or the second adjustment bracket 130. Make it rotate with the first limiting protrusion 112 or the second limiting protrusion 113 as a fulcrum to achieve the purpose of standard rotation.

The reason that the first distance is not equal to the second distance is to better adapt to the difference in the position of the first adjusting bracket 120 or the second adjusting bracket 130 during the unfolding and folding process.

In a further technical solution, both the first adjustment bracket 120 and the second adjustment bracket 130 may include two adjustment rods, and the two adjustment rods included in the first adjustment bracket 120 are the first adjustment rod 121 and the second adjustment rod 122 respectively. , the first adjusting rod 121 and the second adjusting rod 122 are arranged on the first side of the rotating shaft 110 , and the first adjusting rod 121 and the second adjusting rod 122 are respectively matched with the assembly spaces at both ends of the rotating shaft 110 . In this case, the rotating shaft 110 is rotatably connected to the first housing 200 through the first adjusting rod 121 and the second adjusting rod 122. During the specific operation of the electronic device, when the rotating shaft 110 rotates relative to the rotating shaft 110 The first adjusting rod 121 and the second adjusting rod 122 matched with the assembly spaces at both ends also rotate relative to each other, so that the first housing 200 connected with the first adjusting rod 121 and the second adjusting rod 122 is driven.

The two adjusting rods that the second adjusting bracket 130 may include may be a third adjusting rod 131 and a fourth adjusting rod 132, respectively. The third adjusting rod 131 and the fourth adjusting rod 132 are provided on the second side of the rotating shaft 110, and the third adjusting rod The adjusting rod 131 and the fourth adjusting rod 132 are respectively matched with the assembling spaces at both ends of the rotating shaft 110 . In this case, similarly, the rotation shaft 110 is connected to the second housing 300 through the third adjustment rod 131 and the fourth adjustment rod 132 for rotation.
