Summary of the invention

The purpose of the embodiments of the present application is to provide a movement structure, an opening and closing device, and a mobile terminal, which are intended to solve the problem that when the functional structure in the prior art is raised and not retracted relative to the fixed structure, the functional structure and the electric motor are incorrectly pressed. The technical problem of damage to moving structures or devices that collide with functional structures.

In the first aspect, an embodiment of the present application provides a kinematic structure for driving the function structure to rise and fall, including:

A connecting mechanism for connecting the functional structure;

The driving mechanism includes an abutment member, a reset member and a driving member, and the driving member can drive the abutment member to move toward or away from the working direction;

Wherein, the abutting member can drive the connecting mechanism to move when it moves, so that the functional structure can be raised and lowered;

The connecting mechanism can move in the working direction relative to the abutting member when under force, and the resetting member can be used to drive the connecting mechanism toward at least when the connecting mechanism is separated from the abutting member. The elastic restoring force of the movement of the abutting member.

By adopting the above solution, when the driving member drives the abutting member to move in the working direction, the abutting member pushes the connecting mechanism to move in the working direction, and the connecting mechanism drives the functional structure to move to realize the rise of the functional structure; when the driving member drives the abutting member to move in the working direction. When the member moves away from the working direction, if the connecting mechanism separates from the abutting member, the resetting member can generate an elastic reset force that drives the connecting mechanism to move toward the abutting member, so that the connecting mechanism abuts against the abutting member again, so that the connecting structure is simple It can reset and drive the functional structure to reset at the same time; when the functional structure is driven by the external force to drive the connecting mechanism to move in the working direction, the connecting mechanism is separated from the abutting part, and the external force will not force the abutting part and the driving part to reset. The element also generates an elastic restoring force for driving the connecting mechanism to move toward the abutting member, so that the kinetic energy of the external force is converted into the elastic potential energy of the resetting member, the connecting mechanism can be decelerated, and the resetting member releases the elastic resetting force after the external force is removed or reduced. The connecting mechanism abuts against the abutting member again, so that the resetting member has a buffer effect on the connecting mechanism, reducing the impact force that the functional structure or driving member bears when suddenly subjected to external force, and reducing the impact of external force on the functional structure or driving The possible damage caused by the parts extends the service life of the functional structure or the driving parts.

In one of the embodiments of the first aspect, the movement structure further includes an adapter mechanism connected to the connecting mechanism, and the adapter mechanism includes a fixing member for connecting to the functional structure and connecting to the fixing member.

The sliding and rotating around the axis of rotation of the fixed shaft. At this time, the fixed part rotates around the axis of rotation of the fixed shaft, which also drives the rotation of the functional structure. The above-mentioned rotation includes circular motion and eccentric rotation. The functional structure can be displaced during the rotation. , That is, it can achieve ascent in a certain direction; when the functional structure is compressed by external force, it will be displaced by driving the fixed part to rotate. The adapter shaft rotates around the rotation axis of the fixed shaft, and the direction of the working direction is generated during the rotation. Movement to drive the connecting mechanism to move in the working direction and separate from the abutment member. At this time, the resetting member generates an elastic reset force that drives the connecting mechanism to move toward the abutment member, and converts the kinetic energy of the external force into the elastic potential energy of the resetting member. It buffers the impact force received by the functional structure. After reducing or removing the external force, the resetting member can drive the connecting mechanism to move toward the abutting member by releasing the elastic resetting force until the connecting mechanism and the abutting member are facing the working direction. One side abuts to realize the reset of the functional structure, which reduces the pressure on the functional structure itself and the driving parts when the functional structure is suddenly pressed by the external force, reduces the damage to the functional structure or the driving part by the external force, and extends the function The service life of the structure or the driving part; when the driving part drives the abutting part to move in the working direction, the abutting part pushes the connecting mechanism to move in the working direction, and the connecting mechanism drives the adapter shaft to move in the working direction. The sliding of the mechanism rotates in the opposite direction around the axis of rotation of the fixed shaft. At this time, the fixed part also rotates in the opposite direction around the axis of rotation of the fixed shaft, which drives the functional structure to rotate in the opposite direction.

The hole wall of the guide hole 232 is smooth, which facilitates the sliding of the abutting member 23 along the guide rod 225. The guide rod 225 is used to restrict the rotation of the abutting member 23. To prevent the abutment member 23 from being eccentrically loaded during the movement, when the screw 224 rotates, the abutment member 23 moves toward or away from the working direction due to the limiting effect of the guide rod 225, and the abutment member 23 is relative to the guide rod 225 slide. The guide hole 232 can be adapted to the guide rod 225 to weaken the rotation of the abutting member 23 when the screw 224 rotates.

Please refer to Figures 2, 4 and 6, in the illustrated embodiment, the return member 24 includes a first return spring 241 sleeved on the screw 224 and a second return spring 242 sleeved on the guide rod 225, the first Both the return spring 241 and the second return spring 242 are located in the working direction of the connecting mechanism 40. Wherein, the end of the first return spring 241 facing away from the working direction and the end of the second return spring 242 facing away from the working direction are both abutted or fixedly connected to the abutting member 23, and the end of the first return spring 241 facing the working direction is connected to the second The end of the return spring 242 facing the working direction can abut or be fixedly connected to the groove wall of the second support groove 202, and the end of the second return spring 242 facing the working direction can also be fixedly connected with the guide rod 225. At least one of the first return spring 241 and the second return spring 242 may also be replaced by other elastic structures, such as rubber parts. The first return spring 241 and the second return spring 242 can be elastically deformed in the working direction under the action of an external force and generate an elastic return force. In this embodiment, when there is no external force, no matter which position the abutting member 23 moves to, the first return spring 241 and the second return spring 242 can always make the connecting mechanism 40 abut against The abutting member 23, that is, the first return spring 241 and the second return spring 242 are always in a compressed state.

Referring to FIG. 7, in this embodiment, the connecting mechanism 40 includes a connecting portion 41 and a sliding portion 42 connected to the connecting portion 41. The connecting portion 41 is provided with a first limiting hole 411 and a second limiting hole arranged at intervals. 412. The screw 224 is inserted through the first limiting hole 411. The first limiting hole 411 is in clearance fit with the screw 224 and its hole wall is smooth to facilitate the sliding of the connecting portion 41 relative to the screw 224. The guide rod 225 is inserted through The second limiting hole 412, the second limiting hole 412 is fitted or gap-fitted with the guide rod 225 and the hole wall is smooth, so that the connecting portion 41 can slide relative to the guide rod 225. The screw 224 and the guide rod 225 respectively limit the two sides of the connecting portion 41 close to different ends, and prevent the connecting portion 41 from eccentric load or shaking when moving toward or away from the working direction. The abutting member 23 is located on the side of the connecting portion 41 facing away from the working direction, the restoring member 24 is located on the side of the connecting portion 41 facing the working direction, and the restoring member 24 abuts or is fixedly connected to the connecting portion 41.

The sliding portion 42 is provided on the edge of the connecting portion 41 and is used for sliding connection with the adapter mechanism 10. During specific implementation, a sliding groove that is slidably connected to the sliding part 42 can be provided on the adapter mechanism 10. In this embodiment, please refer to Figures 2, 4 and 6, the sliding part 42 is formed along the vertical axis. For the connecting groove 401 extending in the working direction, the adapter mechanism 10 is slidably connected to the connecting groove 401. The two ends of the connecting groove 401 in the extending direction are the extension ends. The two extending ends of the connecting groove 401 can be closed to prevent the adapter mechanism 10 To slip from the connecting groove 401, at least one extending end may also be inserted through, so that the adapter mechanism 10 can penetrate the connecting groove 401 from the through end of the connecting groove 401 to realize the installation with the sliding part 42. Since the sliding connection portion 42 drives the adapter mechanism 10 to move toward or away from the working direction, the notch of the connecting groove 401 facing or facing away from the working direction can easily cause the adapter shaft 13 to slip off the connecting groove 401. In order to solve this problem, In this case, the connecting groove 401 can be arranged such that the opening faces a side perpendicular to the working direction.

Please refer to Figures 2, 4, and 6, the adapter mechanism 10 includes a fixing member 11, a fixing shaft 12, and an adapter shaft 13. The functional structure 90 is connected to the fixing member 11, and the fixing shafts 12 are provided with two fixed shafts, respectively. On both sides of the member 11, the two fixed shafts 12 are located on the same straight line, the two fixed shafts 12 are rotatably connected to the fixed structure, the adapter shaft 13 is connected to the fixed member 11 and is spaced apart from the fixed shaft 12, and the adapter shaft 13 and the fixed shaft The axis of 12 is parallel. When the functional structure 90 is pressed by an external force, since the adapter shaft 13 is slidably connected to the sliding part 42, the sliding part 42 is fixedly connected to the connecting part 41, and the connecting part 41 abuts against the resetting member 24, and the resetting member 24 can at least receive the force. The elastic deformation occurs instantaneously, and further, when the external force presses the functional structure 90, due to the non-rigid connection between the above-mentioned components, the fixed member 11 is allowed to move circularly around the rotation axis of the fixed shaft 12 under the action of the force, and the adapter shaft 13 moves circularly around the axis of rotation of the fixed shaft 12 at the same time, the adapter shaft 13 is received in the connecting groove 401 and is slidably connected to the connecting groove 401, and the adapter shaft 13 can slide in the connecting groove 401 along the extending direction of the connecting groove 401 In the event of accidental pressure, the sliding causes the reset member 24 to be compressed instantaneously to buffer the force of the functional structure 90 and prevent the functional structure 90, the fixing member 11, the fixing structure or the pressure component from being greatly impacted.

In an embodiment of the present application, the positional relationship between the adapter shaft 13 and the fixed shaft 12 can be set as follows: assuming that the line between the axis of the adapter shaft 13 and the axis of the fixed shaft 12 is a first straight line, the connecting mechanism The movement trajectory line of 40 in the working direction is the second straight line. If the first straight line is parallel to the second straight line, when the connecting mechanism 40 moves in the working direction, the force of the adapter shaft 13 toward the working direction is also toward the fixed shaft. 12, instead of generating the circumferential component force that causes the adapter shaft 13 to produce circular motion, the adapter shaft 13 cannot perform circular motion, resulting in the lag of the movement of the connecting mechanism 40. In order to avoid this situation, in this implementation In the example, the first straight line and the second straight line are set at an angle, that is, they are not parallel. In this way, the force of the adapter shaft 13 toward the working direction can be resolved into the component force toward its circular motion direction, so as to facilitate the adapter shaft 13 Perform a circular movement to prevent the connecting mechanism 40 from jamming during the movement.

Optionally, the rotation axis of the fixed shaft 12 is perpendicular to the extension direction of the connecting groove 401, so that when the adapter shaft 13 moves circularly around the rotation axis of the fixed shaft 12, the extension direction of the connecting groove 401 is always parallel to the adapter shaft 13 The rotation plane is the plane where the rotation track of any point on the adapter shaft 13 is located, so that the adapter shaft 13 can always be accommodated in the connecting groove 401 at the same depth without sliding along with its circular motion Out of the connecting groove 401 or touching the bottom of the connecting groove 401, the connection stability between the adapter shaft 13 and the connecting groove 401 is improved.

Please refer to Figures 2, 4 and 6, the first sensing mechanism 30 is connected to the second support frame 212 and is located on the movement track of the sliding part 42. When the connecting mechanism 40 moves toward the working direction, the sliding part 42 It can abut against the first sensing mechanism 30. At this time, the first sensing mechanism 30 is activated. When the first sensing mechanism 30 is activated, the driving member 22 can drive the abutting member 23 to switch between moving toward the working direction and moving away from the working direction. .

Assuming that the functional structure 90 rises or falls with respect to the mounting surface of the fixed structure facing upwards, in this embodiment, during the circular movement of the adapter shaft 13 driven by the connecting mechanism 40, the fixed shaft 12 is always located on the adapter shaft 13 facing the working direction It is always located in the space above the adapter shaft 13, that is, the fixed shaft 12 can rotate within 90° during the movement of the connecting mechanism 40, so that the connecting mechanism 40 only moves toward or away from the working direction. The functional structure 90 can be raised or lowered. If the connecting mechanism 40 can rotate the fixed shaft 12 by more than 90° while moving in one direction, the functional structure 90 will be raised and then lowered or lowered and then raised.

Please refer to Figures 2, 4 and 6, the connecting mechanism 40 has a first operating position, a second operating position and a third operating position in sequence along the operating direction. The connecting mechanism 40 can be positioned at the first operating position, the second operating position and the second operating position. Slide between three working positions. The first sensing mechanism 30 is located on the side of the third working position facing the working direction. The first working position corresponds to the functional structure 90 being raised, that is, the functional structure 90 is in the raised position, the second working position corresponds to the functional structure 90 to return to the initial position, and the third working position corresponds to the functional structure 90 being lowered, that is, the functional structure 90 is in the lowered position .

1 and 2, when the connecting mechanism 40 is in the second operating position, the functional structure 90 is located at the initial position, which is generally located in the inner or edge area of the fixed structure. When the functional structure 90 is required to rise, the driving member 22 Drive the abutment member 23 to move away from the working direction, the connecting mechanism 40 always abuts against the abutment member 23 under the action of the elastic return force of the first return spring 241 and the second return spring 242, that is, as the abutment member 23 moves Moving and moving together back to the working direction, the connecting mechanism 40 can move from the second working position to the first working position. Please refer to Figs. 3 and 4. At this time, the adapter shaft 13 rotates upward under the driving of the connecting mechanism 40. The angle of rotation is approximately 45°, and the functional structure 90 can be raised relative to the fixed structure. Wherein, the functional structure 90 can be rotatably connected to the fixing member 11, so that the functional structure 90 can rotate horizontally along a vertically extending axis after ascending, so as to realize the diversification of functions.

4, when the functional structure 90 rises and is impacted by a downward external force, the functional structure 90 drives the adapter shaft 13 to rotate downward, and the adapter shaft 13 drives the sliding part 42 to move toward the working direction during the rotation. The first return spring 241 and the second return spring 242 are compressed to absorb the kinetic energy of the connecting mechanism 40. The elastic return force increases with the increase of the compression amplitude. The functional structure 90 decelerates under the force of the return member 24, so that the external force is reduced. The impact plays a buffering effect, prevents the functional structure 90 from being damaged when it is suddenly impacted, and prolongs its service life. If the external force is removed, the first return spring 241 and the second return spring 242 release the elastic return force, the connecting mechanism 40 returns to the first operating position, and the functional structure 90 rises without affecting the continued use of the functional structure 90.

3 and 4, when the functional structure 90 needs to be lowered, the driving member 22 drives the abutting member 23 to move toward the working direction, and the abutting member 23 pushes the connecting mechanism 40 to move from the first working position to the second working position. The mechanism 40 drives the adapter shaft 13 to slide along the connecting groove 401 and rotate downwards. The angle of rotation is approximately 45°. At this time, the functional structure 90 moves downward and returns to the initial position. The first return spring 241 and the second return spring 242 Compress and store energy.

When the functional structure 90 is in the initial position, the driving member 22 can be activated by an external electronic control structure, which can be a mobile phone, a smart watch, a notebook computer, or the like. In this embodiment, the driver 22 is triggered to start by an application on the mobile phone. In other embodiments, the driving member 22 can also be activated manually. 5 and 6, specifically, when the functional structure 90 is in the initial position and needs to be raised, the connecting mechanism 40 is in the second working position, and the user presses the functional structure 90 in the initial position so that the fixed shaft 12 rotates approximately 6° At this time, the adapter shaft 13 drives the connecting mechanism 40 to move from the second operating position to the third operating position. The connecting mechanism 40 in the third operating position can abut the first sensing mechanism 30, and the first sensing mechanism 30 is activated. When the driving member 22 is switched to drive the abutment member 23 to move back in the working direction, when the user loosens the functional structure 90, the connecting mechanism 40 is turned back under the action of the elastic restoring force of the first return spring 241 and the second return spring 242. The working direction moves until it abuts against the abutting member 23 and is located at the first working position, so as to realize the ascending operation of the functional structure 90.

When the functional structure 90 has finished rising and needs to return to the initial position, the connecting mechanism 40 is located at the first working position, and the user presses the functional structure 90 so that the fixed shaft 12 rotates approximately 30°, and the adapter shaft 13 drives the connecting mechanism 40 at this time Moving from the first working position to the third working position, the connecting mechanism 40 in the third working position can abut against the first sensing mechanism 30. At this time, the first sensing mechanism 30 is activated, and the driving member 22 is switched to drive the abutting member 23 moves toward the working direction. When the user loosens the functional structure 90, the connecting mechanism 40 moves toward the working direction under the action of the elastic restoring force of the first return spring 241 and the second return spring 242 until it abuts against the abutment 23 When the abutting member 23 stops moving, the connecting mechanism 40 is located at the second working position to realize the lowering and resetting operation of the functional structure 90. During this process, the abutting member 23 can be in a moving state or a stationary state.

Among them, the sliding portion 42 extends in the working direction relative to the connecting portion 41. That is to say, when the functional structure 90 is in the initial position, the functional structure 90 can be raised by manually pressing the functional structure 90. After the functional structure 90 has finished raising, the functional structure 90 can be manually pressed again to return the functional structure 90 to The initial position improves the user's sense of control and operation. In this way, the switching of the driving direction of the driving member 22 each time can be realized electrically or manually, which increases the control way for the lifting of the functional structure 90.

The moving structure can also be applied to automobiles. The fixed structure is the car body, and the functional structure 90 is a reflector. The movement mechanism can control the ejection and retraction of the reflector and protect the reflector. The reflector is subjected to greater external force. It can play a buffering role during impact.

The abutting member 23 is far away from the second sensing mechanism 50 when in the first abutting position, and is in the first abutting position. The second abutting position abuts against the second sensing mechanism 50. That is, when the driving member 22 drives the abutting member 23 to abut against the second sensing mechanism 50, the abutting member 23 is in the second abutting position. At this time, the second sensing mechanism 50 is activated and the driving member 22 is stopped. The driving abutment 23 moves toward the working direction.

When the functional structure 90 is not affected by external force, the connecting mechanism 40 always abuts against the abutting member 23 under the action of the second return spring 242.

Please refer to FIG. 8, when the abutting member 23 is located at the first abutting position, the abutting member 23 abuts against the raised end groove wall, and if there is no external force, the functional structure 90 rises at this time. Referring to FIG. 11, when the abutting member 23 is in the second abutting position, the abutting member 23 abuts against the second sensing mechanism 50, if there is no external force, the functional structure 90 is in the initial position at this time.

In this embodiment, the first sensing mechanism 30 and the second sensing mechanism 50 are electrically connected to an external controller in an external electronic control structure through a conductive metal sheet or a flexible circuit board 60. The driving member 22 can be driven by the control of an external controller. Wherein, the first sensing mechanism 30 and the second sensing mechanism 50 may both be sensing switches.

The external controller can determine the current position of the functional structure 90 by whether the first sensing mechanism 30 and the second sensing mechanism 50 are activated, and control the driving member 22 to drive according to the current position of the functional structure 90.

Referring to FIG. 8, specifically, when the first sensing mechanism 30 is not activated and the second sensing mechanism 50 is not activated, it can be known that the abutting member 23 is in the first abutting position, and the connecting mechanism 40 is in the first working position. The external controller can determine that the functional structure 90 is raised, that is, the functional structure 90 is in the raised position. 10, the functional structure 90 is pressed down at this time until the connecting mechanism 40 moves to the third operating position, at this time the connecting mechanism 40 abuts the first sensing mechanism 30, the first sensing mechanism 30 is activated, and the second sensing mechanism 50 remains unchanged If it is not activated, the external controller can determine that the functional structure 90 is switched from raising to lowering, that is, the functional structure 90 is rotated from the raised position to the lowered position.

When the functional structure 90 rises and is impacted by a downward external force, the functional structure 90 drives the connecting mechanism 40 to move in the working direction through the sliding part 42. The second return spring 242 is compressed to absorb the kinetic energy of the connecting mechanism 40, and the elastic return force follows As the compression amplitude increases, the functional structure 90 decelerates under the force of the reset member 24, so that the impact of the external force is buffered, and the functional structure 90 is prevented from being damaged when it is suddenly impacted and its service life is prolonged. If the functional structure 90 drives the connecting mechanism 40 to directly move from the first operating position to the third operating position, the connecting mechanism 40 is in contact with the first sensing mechanism 30. If the external force is removed, the second return spring 242 releases the elastic return force, and the connecting mechanism 40 returns To the first working position, the functional structure 90 is raised, which does not affect the continued use of the functional structure 90.

The third embodiment of the present application provides an opening and closing device, which includes the movement structure mentioned in the first embodiment above. The movement structure has the same structural features as the movement structure mentioned in the above embodiments and has the same function. , I won’t go into details here. The opening and closing device also includes a first structural member, a second structural member, and a functional structure 90. The first structural member and the second structural member can be buckled together. Optionally, the first structural member and the second structural member may be independent of each other. The two structural parts can also be two structural parts connected by rotation. For example, the first structural member may be the base of the box structure, the second structural member may be an upper cover that covers the base, and the functional structure 90 is connected to the side of the first structural member facing the second structural member through the movement structure or the second structural member. The structural member faces the side of the first structural member. Taking the movement structure connected to the first structural member as an example, the first structural member is equivalent to the fixed structure in the above-mentioned embodiment, and the functional structure 90 is connected to the fixing member 11 in the adapter mechanism 10. When the functional structure 90 rises beyond the first When the structural member faces the mounting surface of the second structural member, if the second structural member is suddenly snapped toward the mounting surface, the functional structure 90 is impacted by the second structural member, the functional structure 90 rotates downward, and the adapter shaft 13 drives the connecting mechanism 40 Moving toward the working direction, the reset member 24 has a buffer effect on the connecting mechanism 40, preventing the second structural member from crushing the functional structure 90 or the functional structure 90 from damaging the second structural member.

In an embodiment, the opening and closing device may be a notebook computer, and the functional structure 90 is a camera.

A notebook computer generally has a keyboard 91 and a screen connected to the keyboard 91. In this embodiment, the first structural member is the keyboard 91, the second structural member is the screen, and the keyboard 91 is provided with keys. With a display screen, in order to solve the hidden problem of the front camera of the notebook computer and increase the screen ratio of the display screen, it has become an important development trend to install the camera on the screen part, which not only improves the sense of technology of the product, but also improves The safety problems in human-computer interaction are solved.

Please refer to Figure 13. A current design idea is to install the functional structure 90, that is, the camera, on the keys of the keyboard 91. This not only increases the screen ratio of the display screen, but also enables the layout of the notebook computer. The internal space of the keyboard part 91 is effectively used. In order to protect user privacy, the camera adopts a pop-up motion structure, that is, the camera will pop out from the keyboard 91 when the camera is needed. When not in use, the camera can be lowered and retracted into the keyboard 91 to achieve physical shielding of the camera. , To prevent privacy leakage. However, in the process of use, users often start to close the screen due to negligence before the camera is lowered and retracted. Excessive force may cause damage to the fragile display screen or cause bump damage to the camera.

In order to solve the above problems and develop more effective applications in real life, the embodiment of the present application adopts a motion structure capable of buffering the impact force, which can be activated in two ways, automatically and manually. The keyboard 91 of the notebook computer is provided with a mounting slot. When the camera is in the initial position, the camera is housed in the mounting slot and the camera direction is forward. When the drive mechanism 20 is activated, the linear motion of the connecting mechanism 40 back to the working direction can be converted into rotation. The circular motion of the connecting shaft 13 and the fixed part 11 drives the camera circular motion along with the circular motion of the adapter shaft 13. The camera rises during the circular motion and its camera direction turns to face diagonally upwards, because the user’s face is obliquely upward when using the laptop. The part is located diagonally above the keyboard, so the camera can be aimed at the user's face at this time to better realize human-computer interaction.

In order to protect the camera, the fixing member 11 is a square box with an accommodating cavity. The camera is located in the accommodating cavity. When the fixing member 11 is in the initial position, it faces the wall of the installation groove and is away from the side of the fixing shaft 12. Hole to avoid the imaging light of the camera. In order to prevent the fixing member 11 from hitting the groove wall of the installation groove during the circular movement, the side surface of the fixing member 11 with the avoiding hole is arranged at an acute angle with the top surface of the fixing member 11 at this time.

In order to improve the user’s sense of operation, the fixing member 11 is at the same level as the keys on the keyboard when the camera is in the initial position. The user can manually press the fixing member 11 like other keys. At this time, the connecting mechanism 40 is moved from the second operating position. Move to the third working position and abut against the first sensing mechanism 30 to activate the driving member 22. The abutting member 23 can move away from the working direction, and a movement space is separated from the connecting mechanism 40. When the user loosens the fixing member At 11 o'clock, the connecting mechanism 40 moves from the third working position to the first working position under the action of the reset member 24, and finally the camera is raised. When the user needs to lower the camera, he can also manually press down the fixing member 11, at this time the connecting mechanism 40 moves from the first working position to the third working position and abuts against the first sensing mechanism 30 to activate the driving member 22 to abut The member 23 can move toward the working direction. When the user loosens the fixing member 11, the connecting mechanism 40 moves from the third working position to the second working position under the action of the reset member 24, wherein the connecting mechanism 40 moves from the third working position to the second working position. In the process of the first working position, it can be reached directly by moving back to the working direction, or it can be moved back to the working direction to between the first working position and the second working position, and then facing towards under the push of the abutting member 23 The working direction moves to the second working position. In this way, the function of manually triggering the rise and fall of the camera is realized, which is in line with the user's usage habits. At this time, the reset member 24 has a buffer effect on the external force manually applied, and prevents the connecting mechanism 40 from crushing the first sensing mechanism 30. When the user forgets to retract the camera and covers the screen, the camera rotates and drops after receiving the momentary impact of the screen, and is buffered by the reset part 24, which reduces the interaction force between the screen and the camera, and reduces the impact of the two Damaged condition.

In other embodiments, the functional structure 90 can also be a flashlight, a fingerprint recognizer or other sensors, and the functional structure 90 can also be provided on the screen, including but not limited to this.

Example four

The fourth embodiment of the present application provides an opening and closing device. Compared with the third embodiment, the difference of this embodiment is that it includes the movement structure described in the second embodiment. In an embodiment, the opening and closing device may be a notebook computer, and the functional structure 90 is a camera. At this time, the first structural member is the keyboard portion 91, and the second structural member is the screen portion.

Please refer to FIG. 13, the functional structure 90 is installed on the keyboard portion 91. In this embodiment, an external electronic control structure is provided inside the notebook computer, and the external electronic control structure has an external controller, and the external controller controls the driving member 22 through a driving chip. The first sensing mechanism 30 (SW1) and the second sensing mechanism 50 (SW2) can input sensing signals to an external controller, and both have two different states. The external controller can output an enable signal (EN) to the drive chip , Direction signal (DIR) and Step signal (STEP), each signal can also represent two different states. Assuming that the two different states are the first state and the second state, the following embodiment uses High to represent the first state State, hereinafter abbreviated as H, Low means the second state, hereinafter abbreviated as L.

Accordingly, the first sensing mechanism 30 is not activated when the state is H, and is activated when the state is L; the second sensing mechanism 50 is not activated when the state is H, and is activated when the state is L. When the state represented by the enable signal is L, the external controller controls the drive chip to start; when the state represented by the enable signal is H, the external controller does not control the drive chip. When the state indicated by the direction signal is L, the activated drive signal controls the motor 221 to rotate in the forward direction, and the motor 221 drives the screw 224 to rotate in the forward direction to drive the abutment member 23 to move back to the working direction; when the direction signal indicates When the state is H, the activated drive chip controls the motor 221 to rotate in the reverse direction, and the motor 221 drives the screw 224 to rotate in the reverse direction to drive the abutment member 23 to move in the working direction. In this embodiment, the state indicated by the direction signal when the state indicated by the enable signal is H is L. When the driving chip is started, the step signal starts to send a fixed number of rising edges to control the number of rotations of the motor 221, so as to obtain the fixed movement distance of the abutting member 23. When the state represented by the enable signal is H, The step signal is no longer sent, and the state represented by the step signal is L at this time. In this embodiment, the above-mentioned fixed number of times is 40, and the distance obtained by the 40 rising edges is the distance between the abutting member 23 from the first abutting position to the second abutting position.

The camera has a power-on state and a power-off state. The camera can shoot when it is on. When the user uses the camera of the laptop computer, the camera is in the on state. If the camera does not drop in time, the computer will suddenly be closed, although due to the buffering effect of the motion structure The damage to the camera and the display is reduced, but it also causes the problem that users often forget that the camera is not turned off, which causes the camera to interfere with the display for a long time, and is turned on for a long time, shortening the service life of the display and the camera.

In order to solve the above-mentioned problem, in this embodiment, the screen part can be provided with a Hall sensor, which can send a status indication signal, and the external controller can receive the status indication signal. When the screen portion is rotated and opened and closed relative to the keyboard portion 91, the state indication signal can change according to the angle between the screen portion and the keyboard portion 91.

Please refer to Table 1 and Figure 14. When the screen is normally opened, the state indicated by the state indicator signal is H. If the user covers the screen portion to the keyboard portion 91, the screen portion will interfere with the camera when the angle between the screen portion and the keyboard portion 91 is less than the preset angle, and press the camera down. In this embodiment, the preset angle is less than or equal to 15°. Wherein, when the included angle between the screen portion and the keyboard portion 91 is less than the aforementioned preset angle, the state indicated by the state indication signal changes from H to L. The external controller starts when the state indicated by the state indication signal becomes L. At this time, the state of the first sensing mechanism 30 is H, the state of the second sensing mechanism 50 is H, and the external controller is based on the state of the second sensing mechanism 50. The state can be judged that the camera is up. At this time, the state represented by the enable signal sent by the external controller is L, the state represented by the direction signal is H, and the step signal sends a fixed number of rising edges per unit time, that is to say , The external controller controls the drive chip to start, the drive chip controls the motor 221 to rotate in the reverse direction, the screw 224 rotates in the reverse direction, and drives the abutment member 23 to move toward the working direction. In this embodiment, 40 step signals are sent within 0.4 seconds. The rising edge, that is, the movement time of the abutting member 23 is 0.4 seconds, and the movement distance is the distance obtained by 40 rising edges, that is, the motor 221 drives the abutting member 23 from the first abutting position within 0.4 seconds. Move to the second abutting position, that is, the camera returns to the initial position. At this time, the state of the first sensing mechanism 30 is H, and the state of the second sensing mechanism 50 is L. When the state of the second sensing mechanism 50 is L, the external controller stops driving the driving member 22, even if the signal indicates The state of is changed to H, the state represented by the step signal is L, and the state represented by the direction signal is L.

When the abutting member 23 is at the second abutting position, the state of the second sensing mechanism 50 is L. In this embodiment, the external controller can switch the camera to the off state when the state of the second sensing mechanism 50 is L , In order to save energy consumption, improve user experience, and avoid the camera is still in the power-on state when it is in the initial position.

For example, the camera set on the laptop can be controlled by the application on the laptop, and the application can also be set on the external terminal, such as control by the application on the mobile phone. The camera on the laptop, etc. If controlled by the above-mentioned application program, the terminal or external terminal equipped with the camera can perform signal transmission with the camera and the external controller. The application program here can be an application program that is used solely to control camera video shooting, or it can be video software or other applications that need to obtain images.

If it is controlled by manual operation, please refer to Table 2 and Figure 15. When the camera is in the initial position, the state of the first sensing mechanism 30 is H and the state of the second sensing mechanism 50 is L. At this time, the camera defaults to the off state. The user needs to raise the camera in the initial position. The user can press down on the camera. The camera drives the connecting mechanism 40 to move from the second working position to the third working position. At this time, the connecting mechanism 40 abuts against the first sensing mechanism 30. The state of a sensing mechanism 30 is changed to L, and the external controller can determine that the camera is not raised through the state of the second sensing mechanism 50. At this time, the state indicated by the enable signal is L, the driving chip is activated, and the state indicated by the direction signal Is L, the drive chip controls the motor 221 to rotate in the forward direction, the screw 224 rotates in the forward direction to drive the abutment member 23 to move back to the working direction, the step signal sends 40 rising edges, and the abutment member 23 moves from the second abutment position to the first In an abutting position, after the user releases the camera, the connecting mechanism 40 abuts against the abutting member 23 under the action of the elastic restoring force of the resetting member 24 until it moves to the first working position and the camera is raised. At this time, the state of the first sensing mechanism 30 is H, the state of the second sensing mechanism 50 is H, the state represented by the enable signal is changed to H, the state represented by the step signal is L, and the state represented by the direction signal is L. This completes the manual operation steps, and the camera can be switched to the on state at this time.

Specifically, please refer to Figure 16. The application sends commands to the DMFT (Devise Media Foudation Transition) Driver, and makes the DMFT Driver call the BIOS (Basic Input Output System) Method to control the external controller. The state of the sensing mechanism 50 is recognized to control the elevation of the camera. The following is an example of the control method controlled by the application program.

Please refer to Table 2 and Figure 17. When the camera is in the initial position, the camera defaults to the off state. When the user opens the application, the camera can be directly switched to the on state, or not directly. Instead, the camera is switched to the on state by operating the application. The external controller determines whether the state of the second sensing mechanism 50 is L. It is recognized whether the second sensing mechanism 50 is activated.

When the state of the second sensing mechanism 50 is L, the external controller recognizes that the second sensing mechanism 50 is activated, and determines that the camera is in the initial position at this time.

This completes the steps for the application to control and start the camera.

Please refer to Table 3 and Figure 18, when the camera is in the open position, the state of the first sensing mechanism 30 is H, the state of the second sensing mechanism 50 is H, and the camera defaults to the on state. If the user needs to restore the raised camera To the initial position, the user can press the camera down, and the camera drives the connecting mechanism 40 to move from the first operating position to the third operating position. At this time, the connecting mechanism 40 abuts against the first sensing mechanism 30, and the state of the first sensing mechanism 30 changes.

Since the state of the second sensing mechanism 50 is H at this time, the external controller can determine that the camera is raised. The state represented by the energy signal is L, the drive chip is activated, the state represented by the direction signal is H, the drive chip controls the motor 221 to rotate in reverse, the screw 224 rotates in the reverse direction to drive the abutment 23 to move in the working direction, and the step signal is sent With 40 rising edges, the abutting member 23 moves from the first abutting position to the second abutting position. After the user releases the camera, the connecting mechanism 40 abuts against the abutting member 23 under the action of the elastic restoring force of the resetting member 24. Until it moves to the second working position, the camera returns to the initial position. At this time, the state of the first sensing mechanism 30 is H, the state of the second sensing mechanism 50 is H, the state represented by the enable signal is changed to H, the state represented by the step signal is L, and the state represented by the direction signal is L. This completes the manual operation steps, and the camera switches to the off state.

If controlled by an application program of an external terminal, the user can directly operate the application program to make the external controller output the same enable signal, direction signal and step signal as in manual operation to complete the raising of the camera. When controlled by an application program, the state of the first sensing mechanism 30 is always H.

Please refer to Table 3 and Figure 19, when the camera is raised, the camera is turned on by default. When the user closes the above application, the camera can be directly switched to the off state, or not directly, but the camera is switched to the off state by operating the application. The external controller recognizes whether the second sensing mechanism 50 is activated by determining whether the state of the second sensing mechanism 50 is L. The specific circumstances are listed below.

When the state of the second sensing mechanism 50 is H, the external controller recognizes that the second sensing mechanism 50 is not activated, and judges that the camera is raised at this time, and the external controller calls the motor driver due to the trigger of the application to start the drive chip At this time, the state represented by the enable signal is L, the drive chip controls the motor 221 to start, the state represented by the direction signal is H, the motor 221 rotates in the reverse direction, and the contact member 23 is driven to move toward the working direction, and the step signal is sent 40 At one rising edge, the abutting member 23 moves from the first abutting position to the second abutting position, driving the connecting mechanism 40 from the first working position to the second working position, and the camera returns to the initial position.
