Because the first shell is movably connected with the second shell, the first shell is switched between a folded state and an unfolded state relative to the second shell. When the first shell is in a folded state relative to the second shell, that is, the electronic device is in the folded state, and when the ambient temperature is low, the electronic device is easy to automatically unfold, which affects the carrying or use of the user.

Content of application

The embodiment of the application provides electronic equipment to solve the problems that in the prior art, when the ambient temperature is low, the electronic equipment is easy to automatically unfold and the carrying or use of a user is influenced.

In order to solve the technical problem, the present application is implemented as follows:

the first magnetic member and the second magnetic member are opposed in a state where the first housing is in a folded state with respect to the second housing; under the condition that the ambient temperature is higher than a preset temperature threshold, the driving assembly drives the first magnetic piece and/or the second magnetic piece to enable the distance between the first magnetic piece and the second magnetic piece to be increased, and the electronic device is switched from the folded state to the unfolded state; under the condition that the ambient temperature is lower than a preset temperature threshold, the first driving assembly drives the first magnetic piece and/or the second magnetic piece, so that the distance between the first magnetic piece and the second magnetic piece is reduced, and the electronic equipment cannot be switched from the folded state to the unfolded state.

In this application embodiment, because first casing and second casing swing joint, consequently, be close to each other at first casing and second casing, perhaps, the in-process that first casing is close to the second casing, first casing and second casing drive the flexible screen and move for the flexible screen is folding. Because the first magnetic part is arranged in the first shell, the second magnetic part is arranged in the second shell, and under the condition that the first shell and the second shell are folded, the first magnetic part is opposite to the second magnetic part. When the ambient temperature is higher than the preset temperature threshold value, the first magnetic part is driven by the first driving assembly to be away from the second magnetic part, so that the distance between the first magnetic part and the second magnetic part is increased, the magnetic force between the first magnetic part and the second magnetic part is reduced, and therefore when the electronic equipment is opened by a user, namely the electronic equipment is unfolded, the user can unfold the electronic equipment by the aid of small force. When ambient temperature is lower than the preset temperature threshold value, the first magnetic part is driven by the first driving assembly to be close to the second magnetic part, so that the distance between the first magnetic part and the second magnetic part is reduced, the magnetic force between the first magnetic part and the second magnetic part is increased, and the first shell and the second shell are not easy to automatically unfold, namely the electronic equipment is not easy to automatically unfold.

That is, in this application embodiment, by providing the first magnetic member, the second magnetic member, and the first driving assembly, the first driving assembly is connected to the second driving assembly, so that the first driving assembly can drive the first magnetic member to be close to or away from the second magnetic member, and thus when the ambient temperature is low, that is, when the ambient temperature is lower than the preset temperature threshold, the first magnetic member is close to the second magnetic member, the distance between the first magnetic member and the second magnetic member is small, and the magnetic force between the first magnetic member and the second magnetic member is large, so that the electronic device is not easily automatically deployed.

In a case where the first casing 10 is in a folded state with respect to the second casing 20, the first magnetic member 40 and the second magnetic member 50 are opposed; under the condition that the ambient temperature is higher than the preset temperature threshold, the first driving assembly 60 drives the first magnetic member 40 and/or the second magnetic member 50, so that the distance between the first magnetic member 40 and the second magnetic member 50 is increased, and the electronic device is switched from the folded state to the unfolded state; in the case that the ambient temperature is lower than the preset temperature threshold, the first driving assembly 60 drives the first magnetic member 40 and/or the second magnetic member 50, so that the distance between the first magnetic member 40 and the second magnetic member 50 becomes smaller, and the electronic device cannot be switched from the folded state to the unfolded state.

In the embodiment of the present application, since the first casing 10 is movably connected to the second casing 20 by the hinge assembly 30, the first casing 10 may be switched between the unfolded state and the folded state with respect to the second casing 20. Since the first magnetic member 40 is disposed in the first casing 10, the second magnetic member 50 is disposed in the second casing 20, and in a case where the first casing 10 is in a folded state with respect to the second casing 20, the first magnetic member 40 is opposed to the second magnetic member 50. In addition, since the driving assembly 60 is connected to the first magnetic member 40 and/or the second magnetic member 50, when the ambient temperature is higher than the preset temperature threshold, the driving assembly 60 drives the first magnetic member 40 and/or the second magnetic member 50, so that the distance between the first magnetic member 40 and the second magnetic member 50 is increased, and the magnetic force between the first magnetic member 40 and the second magnetic member 50 is decreased, so that when a user opens the electronic device, that is, when the electronic device is unfolded, the user needs a small force to unfold the electronic device. When the ambient temperature is lower than the preset temperature threshold, the driving assembly 60 drives the first magnetic member 40 and/or the second magnetic member 50, so that the distance between the first magnetic member 40 and the second magnetic member 50 is reduced, and the magnetic force between the first magnetic member 40 and the second magnetic member 50 is increased, so that the first casing 10 and the second casing 20 are not easily automatically unfolded, that is, the electronic device is not easily automatically unfolded.

That is, in the embodiment of the present application, by providing the first magnetic element 40, the second magnetic element 50, and the driving assembly 60, the driving assembly 60 is connected to the first magnetic element 40 and/or the second magnetic element 50, so that the driving assembly 60 can drive the first magnetic element 40 and/or the second magnetic element 50 to move, and a distance between the first magnetic element 40 and the second magnetic element 50 becomes larger or smaller, so that when an ambient temperature is lower, that is, when the ambient temperature is lower than a preset temperature threshold, a distance between the first magnetic element 40 and the second magnetic element 50 is smaller, and a magnetic force between the first magnetic element 40 and the second magnetic element 50 is larger, so that the electronic device is not easily and automatically unfolded when the electronic device is not subjected to an external force.

It should be noted that, in the embodiment of the present application, a distance between the first magnetic member 40 and the second magnetic member 50 refers to a distance between a first surface of the first magnetic member 40 and a second surface of the second magnetic member 50, where the first surface of the first magnetic member 40 refers to a surface of the first magnetic member 40 facing the second magnetic member 50, and the second surface of the second magnetic member 50 refers to a surface of the second magnetic member 50 facing the first magnetic member 40.

In addition, in the embodiment of the present application, the magnetic pole of the first magnetic member 40 is opposite to the magnetic pole of the second magnetic member 50, for example, the first magnetic member 40 may be an S pole, and the second magnetic member 50 may be an N pole. Of course, the first magnetic member 40 may be an N-pole, and the second magnetic member 50 may be an S-pole.

In addition, in the embodiment of the present application, in the case that the ambient temperature is higher than the preset temperature threshold, the distance between the first magnetic member 40 and the second magnetic member 50 becomes large, and the switching of the electronic device from the folded state to the unfolded state refers to: in electron

When the ambient temperature is lower than the preset temperature threshold, the first driving assembly 60 drives the first magnetic member 40 and/or the second magnetic member 50, so that the distance between the first magnetic member 40 and the second magnetic member 50 becomes smaller, and the electronic device cannot be switched from the folded state to the unfolded state

In addition, in the embodiment of the present application, the preset temperature threshold may be 0 degree, and of course, the preset temperature threshold may also be another temperature value, for example, 1 degree, which is not limited herein.

In addition, in the embodiment of the present application, the electronic device may further include a flexible screen 90, and the flexible screen 90 is connected to the first casing 10 and the second casing 20, respectively.

When the electronic device includes the flexible screen 90, and the flexible screen 90 is connected to the first casing 10 and the second casing 20, respectively, so that the first casing 10 and the second casing 20 can bring the flexible screen 90 to fold or unfold when the first casing 10 and the second casing 20 move relatively. When the flexible screen 90 is unfolded, a user can operate the electronic device through the flexible screen 90, for example, watch a video through the flexible screen, thereby facilitating the user to use the electronic device.

In addition, in the embodiment of the present application, the driving assembly 60 may be in different forms, and specifically, the following are taken as examples for illustration:

(1) as shown in fig. 2 and 3, the driving assembly 60 may include a first driving member 61, the first driving member 61 may be a bimetal, and the first driving member 61 is located in the first housing 10, the bimetal is connected to the first magnetic member 40, and the bimetal is switched between a bent state and a straight state. Under the condition that the ambient temperature is higher than a preset temperature threshold, the bimetal temperature sensing piece is in a bending state, the bimetal temperature sensing piece drives the first magnetic piece 40 to be far away from the second magnetic piece 50, so that the distance between the first magnetic piece 40 and the second magnetic piece 50 is increased, and the electronic device is switched from a folding state to an unfolding state; under the condition that the ambient temperature is lower than the preset temperature threshold, the bimetal temperature sensing piece is in a flat state, the bimetal temperature sensing piece drives the first magnetic piece 40 to be close to the second magnetic piece 50, so that the distance between the first magnetic piece 40 and the second magnetic piece 50 is reduced, and the electronic device is switched from the folded state to the unfolded state.

When the first driving member 61 is a bimetal, the bimetal may change its shape according to the change of the environmental temperature. Because the bimetal temperature sensing piece is connected with the first magnetic part 40, when the environmental temperature changes, the form of the bimetal temperature sensing piece changes, so that the bimetal temperature sensing piece can drive the first magnetic part 40 to move in the process of form change. Specifically, when the ambient temperature changes, the bimetal thermal sensing strip may be switched between a bent state and a straight state, and when the ambient temperature is higher than a preset temperature threshold, the bimetal thermal sensing strip is in the bent state, and the bimetal thermal sensing strip drives the first magnetic member 40 to be away from the second magnetic member 50, so that the distance between the first magnetic member 40 and the second magnetic member 50 is increased, and further, the magnetic force between the first magnetic member 40 and the second magnetic member 50 is decreased. During the process of opening the electronic device, the user needs a small force to overcome the magnetic force between the first magnetic member 40 and the second magnetic member 50, so that the electronic device is opened, i.e. the electronic device is changed from the folded state to the unfolded state. When ambient temperature is less than preset temperature threshold, two golden temperature sensing pieces are in the straight state, two bimetal temperature sensing piece drive first magnetism is close to second magnetic part 50, make the distance between first magnetic part 40 and the second magnetic part 50 diminish, and then the magnetic force grow between first magnetic part 40 and the second magnetic part 50, thereby make electronic equipment under the lower condition of ambient temperature, electronic equipment relies on the magnetic force between first magnetic part 40 and the second magnetic part 50, can continuously keep fold condition, avoid electronic equipment the problem that automatic expansion appears.

It should be noted that, in the embodiment of the present application, the bimetal thermal sensing strip may be located between the first magnetic element 40 and the flexible screen 90, and the bimetal thermal sensing strip is connected to the first magnetic element 40, so that when the bimetal thermal sensing strip is in a bending state, the bimetal thermal sensing strip drives the first magnetic element 40 to be away from the second magnetic element 50, and when the bimetal thermal sensing strip is in a straight state, the bimetal thermal sensing strip drives the first magnetic element 40 to be close to the second magnetic element 50.

In addition, in the embodiment of the present invention, since the bimetal thermal sensing strip changes in form with a temperature change, the electronic device can automatically adjust the distance between the first magnetic member 40 and the second magnetic member 50 by the bimetal thermal sensing strip when the ambient temperature changes.

In addition, in the embodiment of the present application, the number of the bimetal temperature sensing pieces may be set according to actual needs, for example, the number of the bimetal temperature sensing pieces may be two, or may also be three. The number of the bimetal thermal sensing pieces is not limited herein.

In addition, in the embodiment of the present application, as shown in fig. 2, the electronic apparatus may further include a first elastic member 70. The first elastic member 70 is located in the first housing 10, the first elastic member 70 is located between the first magnetic member 40 and the first housing 10, a first end of the first elastic member 70 is fixedly connected to the first housing 10, a second end of the first elastic member 70 is connected to the first magnetic member 40, and the first driving member 61 is located between the first magnetic member 40 and the flexible screen 90. Under the condition that the bimetal thermal sensing strip is in a bending state, the bimetal thermal sensing strip drives the first magnetic element 40 to move, and the first elastic element 70 is in a compression state, so that the first magnetic element 40 is far away from the second magnetic element 50; under the condition that the bimetal thermal sensing strip is in a flat state, the bimetal thermal sensing strip and the first elastic element 70 drive the first magnetic element 40 to move, so that the first magnetic element 40 is close to the second magnetic element 50.

Since the electronic device includes the first elastic element 70, the first elastic element 70 is located in the first housing 10, the first elastic element 70 is located between the first magnetic element 40 and the first housing 10, a first end of the first elastic element 70 is fixedly connected to the first housing 10, and a second end of the first elastic element 70 is connected to the first magnetic element 40, when the first magnetic element 40 moves along with the configuration change of the first driving element 61, that is, when the first magnetic element 40 moves along with the configuration change of the bimetal thermal sensing strip, the first magnetic element 40 can apply a force to the first elastic element 70, so that the configuration of the first elastic element 70 changes. Specifically, under the condition that the bimetal thermal sensing strip is in the bending state, the bimetal thermal sensing strip drives the first magnetic member 40 to move, and at this time, the first magnetic member 40 may apply pressure to the first elastic member 70, so that the first elastic member 70 is in the compression state, and the first magnetic member 40 is far away from the second magnetic member 50. When the bimetal thermal sensing strip is in a flat state, the bimetal thermal sensing strip can drive the first magnetic element 40 to move, and the first elastic element 70 can be changed from a compressed state, that is, the first elastic element 70 can be extended from the compressed state, and the first elastic element 70 applies force to the first magnetic element 40, at this time, the bimetal thermal sensing strip and the first elastic element 70 simultaneously drive the first magnetic element 40 to move, so that the first magnetic element 40 is close to the second magnetic element 50. That is, by providing the first elastic member 70, when the bimetal thermal sensing strip is in a flat state, the first elastic member 70 applies a force to the first magnetic member 40, so that the first magnetic member 40 can be moved by the bimetal thermal sensing strip and the first elastic member 70 at the same time, and the moving speed of the first magnetic member 40 is increased.

It should be noted that, in the embodiment of the present application, the first elastic member 70 may be a spring, and of course, the first elastic member 70 may also be another elastic device, such as an elastic sheet, and as for the type of the first elastic member 70, the embodiment of the present application is not limited herein.

In addition, in the embodiment of the present application, the number of the first elastic members 70 may be set according to actual requirements, for example, the number of the first elastic members 70 may be three, or may be two. The number of the first elastic members 70 is not limited herein.

(2) As shown in fig. 4, the driving assembly 60 may include a first driving member 61, and the first driving member 61 may be a motor, and the motor is connected to the first magnetic member 40. Under the condition that the ambient temperature is higher than the preset temperature threshold, the motor receives a first instruction, so that the motor drives the first magnetic part 40 to be far away from the second magnetic part 50; under the condition that the ambient temperature is lower than the preset temperature threshold, the motor receives a second instruction, so that the motor drives the first magnetic member 40 to approach the second magnetic member 50.

When the first driving member 61 is a motor and the motor is connected to the first magnetic member 40, the motor can drive the first magnetic member 40 to move. Specifically, under the condition that the ambient temperature is higher than the preset temperature threshold, the motor may receive the first instruction, so that the motor drives the first magnetic member 40 to be away from the second magnetic member 50, the distance between the first magnetic member 40 and the second magnetic member 50 is increased, and the magnetic force between the first magnetic member 40 and the second magnetic member 50 is decreased. During the process of opening the electronic device, the user needs a small force to overcome the magnetic force between the first magnetic member 40 and the second magnetic member 50, so that the electronic device is opened, i.e. the electronic device is changed from the folded state to the unfolded state. When ambient temperature is less than preset temperature threshold, the motor drives first magnetism spare 40 and removes, make first magnetism be close to second magnetism spare 50, the distance between first magnetism spare 40 and the second magnetism spare 50 diminishes, magnetic force grow between first magnetism spare 40 and the second magnetism spare 50, thereby make electronic equipment under the lower condition of ambient temperature, electronic equipment relies on the magnetic force between first magnetism spare 40 and the second magnetism spare 50, can continuously keep fold condition, avoid electronic equipment to appear the problem of automatic expansion.

It should be noted that, in the embodiment of the present application, the connection manner of the motor and the first magnetic member 40 may be: as shown in fig. 4, a first transmission rod 611 is connected to a transmission shaft of the motor, a thread is disposed on the first transmission rod 611, and a first sliding block 612 is sleeved on the first transmission rod 611 and connected to the first magnetic element 40, that is, the rotation motion of the first transmission rod 611 is converted into a linear motion of the first sliding block 612 by using the principle of a lead screw nut, so that the first sliding block 612 can move along the axial direction of the first transmission rod 611. At this time, when the motor operates, the motor drives the transmission shaft to rotate, and the transmission shaft drives the first transmission rod 611 to rotate, so that the first sliding block 612 moves along the axial direction of the first transmission, and the first sliding block 612 drives the first magnetic member 40 to move away from or close to the second magnetic member 50. Specifically, when the motor receives the first command, the transmission shaft of the motor may rotate clockwise, so that the first slider 612 drives the first magnetic member 40 to move away from the second magnetic member 50. When the motor receives the second command, the transmission shaft of the motor may rotate counterclockwise, so that the first slider 612 drives the first magnetic member 40 to approach the second magnetic member 50.

Of course, when the motor receives the first command, the transmission shaft of the motor may also rotate counterclockwise, so that the first slider 612 drives the first magnetic member 40 to move away from the second magnetic member 50. When the motor receives the second command, the transmission shaft of the motor may also rotate clockwise, so that the first slider 612 drives the first magnetic member 40 to approach the second magnetic member 50. The embodiments of the present application are not limited herein.

In addition, in the embodiment of the present application, the electronic device may further include a temperature sensor (not shown in the figure) and a control circuit (not shown in the figure). The temperature sensor and the control circuit are located in the first housing 10, the temperature sensor is electrically connected to the control circuit, and the control circuit is electrically connected to the first driving member 61. Under the condition that the ambient temperature is higher than a preset temperature threshold value, the temperature sensor sends a first signal to the control circuit so that the control circuit sends a first instruction to the motor; and under the condition that the ambient temperature is lower than the preset temperature threshold, the temperature sensor sends a second signal to the control circuit so that the control circuit sends a second instruction to the motor.

When the electronic device includes the temperature sensor and the control circuit, the temperature sensor and the control circuit are located in the first housing 10, the temperature sensor is electrically connected to the control circuit, the control circuit is electrically connected to the first driving member 61, that is, the control circuit is electrically connected to the motor, at this time, the temperature sensor can detect the ambient temperature, compare the detected ambient temperature with a preset temperature threshold, and then send a signal to the control circuit, so that the control circuit controls the motor, and further, the motor drives the first magnetic member 40 to move. Specifically, under the condition that the ambient temperature is higher than the preset temperature threshold, the temperature sensor may send a first signal to the control circuit, and after the control circuit receives the first signal, the control circuit sends a first instruction to the motor, so that the motor drives the first magnetic member 40 to be away from the second magnetic member 50. Under the condition that the ambient temperature is lower than the preset temperature threshold, the temperature sensor may send a second signal to the control circuit, and after the control circuit receives the second signal, the control circuit sends a second instruction to the motor, so that the motor drives the first magnetic member 40 to be close to the second magnetic member 50. That is, by providing the temperature sensor and the control circuit in the electronic device, the electronic device can automatically adjust the distance between the first magnetic member 40 and the second magnetic member by the motor when the ambient temperature changes.

In addition, in the embodiment of the present application, the first housing 10 is provided with a control button (not shown in the figure). The control button is electrically connected to the first driving member 61, and the control button is used for sending an instruction to the first driving member 61, so that the first driving member 61 drives the first magnetic member 40 to move.

When the control button is disposed on the first casing 10, and the control button is electrically connected to the first driving member 61, that is, when the control button is electrically connected to the motor, at this time, the control button can send an instruction to the first driving member 61, that is, by pressing the control button, different instructions can be sent to the motor, so that the first driving member 61, that is, the motor drives the first magnetic member 40 to move. That is, by providing the control button, the user can autonomously control the first magnetic member 40 to move through the motor.

For example, pressing the control key once may send a first instruction to the motor, so that the motor drives the first magnetic member 40 to be away from the second magnetic member 50, and pressing the control key twice continuously may send a second instruction to the motor, so that the motor drives the first magnetic member 40 to be close to the second magnetic member 50. For another example, when the duration of pressing the control key is less than the preset duration, a first instruction may be sent to the motor, so that the motor drives the first magnetic member 40 to be away from the second magnetic member 50, and when the duration of pressing the control key is greater than the preset duration, a second instruction may be sent to the motor, so that the motor drives the first magnetic member 40 to be close to the second magnetic member 50.

Additionally, in some embodiments, as shown in fig. 5, the drive assembly 60 may further include a second drive member 62. The second driving member 62 is located in the second housing 20 and connected to the second magnetic member 50. Under the condition that the ambient temperature is higher than the preset temperature threshold, the second driving element 62 drives the second magnetic element 50 to be away from the first magnetic element 40, so that the distance between the first magnetic element 40 and the second magnetic element 50 becomes larger; in the case that the ambient temperature is lower than the preset temperature threshold, the second driving element 62 drives the second magnetic element 50 to approach the first magnetic element 40, so that the distance between the first magnetic element 40 and the second magnetic element 50 becomes smaller.

When the electronic device includes the second driving element 62, the second driving element 62 is located in the second housing 20, and the second driving element 62 is connected to the second magnetic element 50, at this time, when the ambient temperature changes, the second driving element 62 can also drive the second magnetic element 50, so that the second magnetic element 50 moves. Specifically, when the ambient temperature is higher than the preset temperature threshold, the second driving element 62 drives the second magnetic element 50 to move away from the first magnetic element 40, so that the distance between the first magnetic element 40 and the second magnetic element 50 becomes larger, and the magnetic force between the first magnetic element 40 and the second magnetic element 50 becomes smaller. Under the condition that the ambient temperature is lower than the preset temperature threshold, the second driving element 62 drives the second magnetic element 50 to approach the first magnetic element 40, so that the distance between the first magnetic element 40 and the second magnetic element 50 becomes smaller, and the magnetic force between the first magnetic element 40 and the second magnetic element 50 becomes larger. That is, by providing the second driving element 62, when the first driving element 61 drives the first magnetic element 40, the second magnetic element 50 can drive the second magnetic element 50 at the same time, so that the first magnetic element 40 is under the action of the first driving element 61, and under the action of the second driving element 62, the first magnetic element 40 and the second magnetic element 50 are close to or far away from each other, so that the rate of change of the distance between the first magnetic element 40 and the second magnetic element 50 is large, and the efficiency is improved.

Specifically, when the ambient temperature is higher than the preset temperature threshold, the first driving element 61 drives the first magnetic element 40 to be away from the second magnetic element 50, and the second driving element 62 drives the second magnetic element 50 to be away from the first magnetic element 40, that is, the first magnetic element 40 and the second magnetic element 50 are away from each other, so that the rate of change of the distance between the first magnetic element 40 and the second magnetic element 50 is increased. When the ambient temperature is lower than the preset temperature threshold, the first driving element 61 drives the first magnetic element 40 to approach the second magnetic element 50, and the second driving element 62 drives the second magnetic element 50 to approach the first magnetic element 40, that is, the first magnetic element 40 and the second magnetic element 50 approach each other, so that the rate of change of the distance between the first magnetic element 40 and the second magnetic element 50 becomes larger.

In addition, in the embodiment of the present application, as shown in fig. 5 and 6, the second driving member 62 may be a bimetal, which is connected to the second magnetic member 50 and is switched between a bent state and a straight state. Under the condition that the ambient temperature is higher than a preset temperature threshold, the bimetal temperature sensing piece is in a bending state, and the bimetal temperature sensing piece drives the second magnetic piece 50 to be far away from the first magnetic piece 40, so that the distance between the first magnetic piece 40 and the second magnetic piece 50 is increased; under the condition that the ambient temperature is lower than the preset temperature threshold, the bimetal temperature sensing strip is in a flat state, and the bimetal temperature sensing strip drives the second magnetic element 50 to be close to the first magnetic element 40, so that the distance between the first magnetic element 40 and the second magnetic element 50 is reduced.

When the second driving member 62 is a bimetal, the bimetal may change its shape according to the change of the environmental temperature. Because the bimetal temperature sensing piece is connected with the second magnetic part 50, when the environmental temperature changes, the shape of the bimetal temperature sensing piece changes, so that the bimetal temperature sensing piece can drive the second magnetic part 50 to move in the process of the shape change. Specifically, when the ambient temperature changes, the bimetal thermal sensing strip may be switched between a bent state and a straight state, and when the ambient temperature is higher than a preset temperature threshold, the bimetal thermal sensing strip is in the bent state, and the bimetal thermal sensing strip drives the second magnetic member 50 to be away from the first magnetic member 40, so that the distance between the second magnetic member 50 and the first magnetic member 40 is increased, and further, the magnetic force between the second magnetic member 50 and the first magnetic member 40 is decreased. During the process of opening the electronic device, the user needs a small force to overcome the magnetic force between the second magnetic member 50 and the first magnetic member 40, so that the electronic device is opened, i.e. the electronic device is changed from the folded state to the unfolded state. When ambient temperature is less than preset temperature threshold, two golden temperature sensing pieces are in the straight state, two metal temperature sensing piece drive second magnetism are close to first magnetic part 40, make the distance between second magnetic part 50 and the first magnetic part 40 diminish, and then the magnetic force grow between second magnetic part 50 and the first magnetic part 40, thereby make electronic equipment under the lower condition of ambient temperature, electronic equipment relies on second magnetic part 50 and first magnetic part 40, can make electronic equipment continuously keep fold condition, avoid electronic equipment the problem that automatic expansion appears.

It should be noted that, in the embodiment of the present application, the bimetal thermal sensing strip may be located between the second magnetic member 50 and the flexible screen 90, and the bimetal thermal sensing strip is connected to the second magnetic member 50, so that when the bimetal thermal sensing strip is in a bending state, the bimetal thermal sensing strip drives the second magnetic member 50 to be away from the first magnetic member 40, and when the bimetal thermal sensing strip is in a straight state, the bimetal thermal sensing strip drives the second magnetic member 50 to be close to the first magnetic member 40.

In addition, as shown in fig. 5 and 6, when the second driving element 62 is a bimetal, in this case, the first driving element 61 may be a bimetal, and when the ambient temperature is higher than the preset temperature threshold, the first driving element 61 and the second driving element 62, that is, the bimetal in the first casing 10 and the bimetal in the second casing 20 respectively drive the first magnetic element 40 and the second magnetic element 50 to move, so that the first magnetic element 40 and the second magnetic element 50 are away from each other. When the ambient temperature is lower than the preset temperature threshold, the first driving element 61 and the second driving element 62, that is, the bimetal thermal sensing strip in the first casing 10 and the bimetal thermal sensing strip in the second casing 20 respectively drive the first magnetic element 40 and the second magnetic element 50 to move, so that the first magnetic element 40 and the second magnetic element 50 are close to each other. That is, the bimetal thermal sensing strip in the first casing 10 and the bimetal thermal sensing strip in the second casing 20 can be simultaneously changed in shape.

In addition, in the embodiment of the present application, when the second driving element 62 is a bimetal thermal sensing strip, in this case, the first driving element 61 may be a motor, and when the ambient temperature is higher than the preset temperature threshold, the first driving element 61 and the second driving element 62, that is, the motor in the first housing 10 and the bimetal thermal sensing strip in the second housing 20 respectively drive the first magnetic element 40 and the second magnetic element 50 to move, so that the first magnetic element 40 and the second magnetic element 50 are away from each other. When the ambient temperature is lower than the preset temperature threshold, the first driving element 61 and the second driving element 62, that is, the motor in the first housing 10 and the bimetal thermal sensing strip in the second housing 20 respectively drive the first magnetic element 40 and the second magnetic element 50 to move, so that the first magnetic element 40 and the second magnetic element 50 are close to each other. That is, while the motor in the first housing 10 moves the first magnetic member 40, the bimetal thermal sensing strip in the second housing 20 moves the second magnetic member 50.

In addition, in the embodiment of the present application, as shown in fig. 5, the electronic apparatus may further include a second elastic member 80. The second elastic element 80 is located in the second housing 20, the second elastic element 80 is located between the second magnetic element 50 and the second housing 20, a first end of the second elastic element 80 is fixedly connected with the second housing 20, a second end of the second elastic element 80 is connected with the second magnetic element 50, and the second driving element 62 is located between the second magnetic element 50 and the flexible screen 90. Under the condition that the bimetal temperature sensing piece is in a bending state, the bimetal temperature sensing piece drives the second magnetic element 50 to move, and the second elastic element 80 is in a compression state, so that the second magnetic element 50 is far away from the second magnetic element 50; under the condition that the bimetal temperature sensing piece is in a flat state, the bimetal temperature sensing piece and the second elastic element 80 drive the second magnetic element 50 to move, so that the second magnetic element 50 is close to the second magnetic element 50.

Since the electronic device includes the second elastic element 80, the second elastic element 80 is located in the second housing 20, the second elastic element 80 is located between the second magnetic element 50 and the second housing 20, a first end of the second elastic element 80 is fixedly connected to the second housing 20, and a second end of the second elastic element 80 is connected to the first magnetic element 40, when the second magnetic element 50 moves along with the second driving element 62, that is, the second magnetic element 50 moves along with the change of the form of the bimetal thermal sensing strip, the second magnetic element 50 can apply force to the second elastic element 80, so that the form of the second elastic element 80 changes. Specifically, under the condition that the bimetal thermal sensing strip is in the bending state, the bimetal thermal sensing strip drives the second magnetic member 50 to move, at this time, the second magnetic member 50 may apply pressure to the second elastic member 80, so that the second elastic member 80 is in the compression state, and the second magnetic member 50 is far away from the second magnetic member 50. When the bimetal thermal sensing strip is in a flat state, the bimetal thermal sensing strip can drive the second magnetic element 50 to move, and the second elastic element 80 can change from a compression state, that is, the second elastic element 80 can extend from the compression state, and the second elastic element 80 applies force to the second magnetic element 50, at this time, the bimetal thermal sensing strip and the second elastic element 80 simultaneously drive the second magnetic element 50 to move, so that the second magnetic element 50 is close to the second magnetic element 50. That is, by providing the second elastic member 80, when the bimetal thermal sensing strip is in a flat state, the second elastic member 80 applies a force to the second magnetic member 50, so that the second magnetic member 50 can be driven by the bimetal thermal sensing strip and the second elastic member 80 to move at the same time, and the moving speed of the second magnetic member 50 is increased.

The number of the second elastic members 80 is not limited herein.

In addition, in the embodiment of the present application, as shown in fig. 5 and 6, when the second driving element 62 is a bimetal thermal sensing strip and the second elastic element 80 is disposed in the second housing 20, the first driving element may be a bimetal thermal sensing strip and the first elastic element 70 is disposed in the first housing 10, at this time, the first elastic element 70 and the second elastic element 80 may respectively apply force to the first magnetic element 40 and the second magnetic element 50, so that the distance change rate between the first magnetic element 40 and the second magnetic element 50 is large.

In addition, in the embodiment of the present application, the second driving element 62 may also be a motor, and the motor is connected to the second magnetic element 50. Under the condition that the environmental temperature is higher than the preset temperature threshold, the motor receives a third instruction, so that the motor drives the second magnetic part 50 to be far away from the first magnetic part 40; under the condition that the ambient temperature is lower than the preset temperature threshold, the motor receives a fourth instruction, so that the motor drives the second magnetic member 50 to approach the first magnetic member 40.

When the second driving member 62 is a motor and the motor is connected to the second magnetic member 50, the motor can drive the second magnetic member 50 to move. Specifically, under the condition that the ambient temperature is higher than the preset temperature threshold, the motor may receive a third instruction, so that the motor drives the second magnetic member 50 to be away from the first magnetic member 40, the distance between the first magnetic member 40 and the second magnetic member 50 is increased, and the magnetic force between the first magnetic member 40 and the second magnetic member 50 is decreased. During the process of opening the electronic device, the user needs a small force to overcome the magnetic force between the first magnetic member 40 and the second magnetic member 50, so that the electronic device is opened, i.e. the electronic device is changed from the folded state to the unfolded state. When ambient temperature is less than preset temperature threshold, the motor drives second magnetism spare 50 and removes, make the second magnetism be close to second magnetism spare 50, the distance between first magnetism spare 40 and the second magnetism spare 50 diminishes, magnetic force grow between first magnetism spare 40 and the second magnetism spare 50, thereby make electronic equipment under the lower condition of ambient temperature, electronic equipment relies on the magnetic force between first magnetism spare 40 and the second magnetism spare 50, can continuously keep fold condition, avoid electronic equipment to appear the problem of automatic expansion.

At this time, when the motor operates, the motor drives the transmission shaft to rotate, and the transmission shaft drives the second transmission rod 621 to rotate, so that the second slider 622 moves along the axial direction of the second transmission, and the second slider 622 drives the second magnetic member 50 to move away from or close to the first magnetic member 40. Specifically, when the motor receives the third command, the transmission shaft of the motor may rotate clockwise, so that the second slider 622 drives the second magnetic member 50 to be away from the first magnetic member 40. When the motor receives the fourth command, the transmission shaft of the motor may rotate counterclockwise, so that the second slider 622 drives the second magnetic member 50 to approach the first magnetic member 40.
