With the development of science and technology, electronic devices such as tablet computers and mobile phones are favored by more people due to their portability. A foldable holder is used for placing a tablet computer or a mobile phone, to facilitate people to use the tablet computer or the mobile phone more conveniently. The existing hinge-type foldable holder mainly relies on the difference in torque of the main and auxiliary rotating shafts to realize the opening and closing of the holder. However, during continuous opening and closing processes of the foldable holder, the torque of the rotating shafts is attenuated, which leads to abnormal opening and closing.

SUMMARY

The application provides a foldable holder and an electronic device, to resolve the problem of abnormal opening and closing of the foldable holder in the prior art.

A bottom plate is rotationally connected to a first support plate through a first rotating portion, and a second support plate is rotationally connected to a side of the first support plate through a second rotating portion: and the first rotating portion and the second rotating portion are located on two opposite sides of the first support plate. A clamping portion is mounted on the first support plate and slidable relative to the first support plate.

When the foldable holder100is in the closed state, the first support plate20and the second support plate30are arranged side by side along the X direction, and both the first support plate20and the second support plate30are stacked with the bottom plate10. It can be understood that the first support plate20and the second support plate30are in an integral flat shape. The second clamping end512of the clamping body51is located in the second clamping groove441, and clamps the second rotating shaft44, to prevent the second rotating shaft44from rotating in the first fixing plate421and the third fixing plate431, to prevent the second support plate30from rotating relative to the first support plate20. At the same time, the first clamping end511is staggered with the first clamping groove411, and the first clamping end511abuts against a surface of the first rotating shaft41. The elastic body52is in the pre-compressed state, and an elastic restoring force of the elastic body52has a component force towards the first rotating shaft41, so that the clamping body51tends to slide towards the first rotating shaft41.

The first support plate20or the second support plate30is rotated counterclockwise ω1, so that the first shaft sleeve22rotates counterclockwise ω1around the first rotating shaft41, to drive the first support plate20to rotate counterclockwise ω1around the first rotating shaft41. That is, the first support plate20and the second support plate30rotate counterclockwise ω1together relative to the bottom plate10. In this case, when the clamping portion50follows the first support plate20to rotate relative to the first rotating shaft41until the first clamping end511rotates to be opposite to the first clamping groove411, and the elastic body52is elastically recovered, to drive the clamping body51to slide towards the first rotating shaft41, so that the first clamping end511is located in the first clamping groove411and clamps the first rotating shaft41, so that the foldable holder100is in the semi-unfolded state (as shown inFIG.2).

In this embodiment, by arranging the clamping portion50, when the foldable holder100is in the closed state, the clamping body51clamps the second rotating shaft44, and when the first support plate20or the second support plate30is rotated, the first support plate20and the second support plate30can remain stationary, that is, the first support plate20and the second support plate30can rotate together relative to the bottom plate10, so that the foldable holder100can be transformed from the closed state to the semi-unfolded state.

Referring toFIG.2andFIG.11.FIG.11is a partial schematic structural diagram of the foldable holder100shown inFIG.2in a semi-unfolded state.

When the foldable holder100is in the semi-unfolded state, the first support plate20is parallel to the second support plate30, and the angle between the first support plate20and the bottom plate10is the first angle α. The first clamping end511of the clamping body51is located in the first clamping groove411, and clamps the first rotating shaft41, the locking member locks the first rotating shaft41, and the clamping body51and the locking member lock the first rotating shaft41together, to prevent the first support plate20from continuing to rotate around the first rotating shaft41. The second clamping end512is disengaged from the second clamping groove441, and releases the second rotating shaft44. Rotating the second support plate30) can drive the second support plate30to rotate relative to the first support plate20.

In this case, the angle between the second support plate30and the first support plate20is the second angle β, and the angle between the first support plate20and the bottom plate10is the first angle α. The locating member locates the second support plate30, to remain the angle between the first support plate20and the second support plate30at the second angle β, and remain the foldable holder100in the open state. In addition, a state of the clamping body51is the same as a state of the foldable holder100in the semi-unfolded state, and the first clamping end511of the clamping body51is located in the first clamping groove411and clamps the first rotating shaft41, to prevent the first support plate20from rotating relative to the bottom plate10.

It should be noted that when the foldable holder100is in the open state, a force required to rotate the second support plate30clockwise ω2is less than a locking force of the clamping body51and a locking member on the first rotating shaft41, to ensure that when the second support plate30is rotated clockwise ω2, the second support plate30rotates relative to the first support plate20, and the first support plate20and the bottom plate10are relatively stationary, thereby ensuring opening and closing logic of the foldable holder100.

The first clamping end511of the clamping body51is located in the first clamping groove411and clamps the first rotating shaft41. The first hinge42and the second hinge43locate the second support plate30, to prevent the second support plate30from continuing to rotate clockwise ω2relative to the first support plate20, and to remain the first support plate20and the second support plate30in the parallel state.

The first support plate20or the second support plate30is rotated clockwise @2, so that the first shaft sleeve22rotates clockwise ω2around the first rotating shaft41, to drive the first support plate20to rotate clockwise ω2around the first rotating shaft41. That is, the first support plate20and the second support plate30rotate clockwise ω2together relative to the bottom plate10. In this case, the clamping portion50follows the first support plate20to rotate relative to the first rotating shaft41, the first clamping end511is disengaged from the first clamping groove411, and under an abutting effect of the first rotating shaft41, the clamping body51moves towards the second rotating shaft44until the second clamping end512is located in the second clamping groove441and clamps the second rotating shaft44, so that the foldable holder100is in the closed state shown inFIG.1.

In this embodiment, one side wall of the first clamping groove411is a curved surface. When the foldable holder100is transformed from the semi-unfolded state to the closed state, and the first support plate20is rotated clockwise ω2, the clamping portion50follows the first support plate20to rotate relative to the first rotating shaft41, and the first clamping end511slides out of the curved side wall of the first clamping groove411and is disengaged from the first clamping groove411.

It can be understood that the bump is located in the first clamping groove411.

When the foldable holder100is in the closed state, the bump412abuts against the first clamping end511, and the second clamping end512of the clamping body51is located in the second clamping groove441and clamps the second rotating shaft44, to prevent the second rotating shaft44from rotating, to prevent the second support plate30from rotating relative to the first support plate20. The first support plate20is rotated, so that the first shaft sleeve22rotates around the first rotating shaft41, to drive the first support plate20to rotate around the first rotating shaft41.

The first support plate20or the second support plate30is rotated counterclockwise ω1, so that the first support plate20and the second support plate30rotate counterclockwise ω1together relative to the bottom plate10. In this case, when the clamping portion50follows the first support plate20to rotate relative to the first rotating shaft41until the first clamping end511rotates to be disengaged from the bump412, the elastic body52is elastically recovered, to drive the clamping body51to slide towards the first rotating shaft41, so that the second clamping end512is disengaged from the bump412, so that the foldable holder100is in the semi-unfolded state (as shown inFIG.2).

When the foldable holder100is in the semi-unfolded state, the locking member locks the first rotating shaft41, to prevent the first support plate20from continuing to rotate. At the same time, the second clamping end512is disengaged from the second clamping groove441, and releases the second rotating shaft44. Rotating the second support plate30can drive the second support plate30to rotate relative to the first support plate20.

The second support plate30is rotated counterclockwise ω1to drive the second rotating shaft44to rotate counterclockwise ω1relative to the first support plate20, to drive the second fixing plate422to rotate counterclockwise ω1relative to the first fixing plate421, and the fourth fixing plate432rotates counterclockwise ω1relative to the third fixing plate431, to drive the second support plate30to rotate counterclockwise ω1relative to the first support plate20, so that the foldable holder100is in the open state (as shown inFIG.3). When the foldable holder100is in the open state, the state of the clamping body51is the same as the state of the foldable holder100in the semi-unfolded state, the first clamping end511of the clamping body51is disengaged from the bump412, and the second clamping end512is disengaged from the second clamping groove441, and releases the second rotating shaft44.

The second support plate30is rotated clockwise ω2, to drive the second rotating shaft44to rotate clockwise ω2relative to the first support plate20, to drive the second fixing plate422to rotate clockwise ω2relative to the first fixing plate421, and the fourth fixing plate432rotates clockwise ω2relative to the third fixing plate431, to drive the second support plate30to rotate clockwise ω2relative to the first support plate20until the first support plate20is coplanar with the second support plate30, so that the foldable holder100is in the semi-unfolded state shown inFIG.2.

When the foldable holder100is in the semi-unfolded state, the first support plate20or the second support plate30is rotated clockwise ω2, so that the first shaft sleeve22rotates clockwise ω2around the first rotating shaft41, to drive the first support plate20to rotate clockwise ω2around the first rotating shaft41. That is, the first support plate20and the second support plate30rotate clockwise ω2together relative to the bottom plate10. In this case, the clamping portion50follows the first support plate20to rotate relative to the first rotating shaft41, and the bump412abuts against the first clamping end511, so that the clamping body51moves towards the second rotating shaft44until the second clamping end512is located in the second clamping groove441and clamps the second rotating shaft44, so that the foldable holder100returns to the closed state shown inFIG.1.

In this embodiment, a side surface of the bump412is a curved surface. When the foldable holder100is transformed from the semi-unfolded state to the closed state, the first support plate20is rotated clockwise ω2, the clamping portion50follows the first support plate20to rotate relative to the first rotating shaft41, and the first clamping end511slides along the side surface of the bump412until it is opposite to the bump, so that the bump412abuts against the first clamping end.
