Referring to fig. 1, a functional device 100 according to an embodiment of the present disclosure is shown. The functional component 100 can be applied to an electronic device 200. The electronic device 200 according to the embodiment of the present application may be any device having communication and storage functions, for example: the system comprises intelligent equipment with a network function, such as a tablet Computer, a mobile phone, an electronic reader, a remote controller, a Personal Computer (PC), a notebook Computer, vehicle-mounted equipment, a network television, wearable equipment and the like.

Referring to fig. 1 to 4, the functional module 100 includes a base 1, a sliding seat 2 and a driving module 3. The sliding seat 2 is telescopically and slidably connected to the base 1. And the sliding seat 2 is provided with a camera module 4. The camera module 4 moves along with the sliding seat 2. The driving component 3 is arranged in the base 1. The driving assembly 3 includes a motor 31, a lead screw 32, a slider 33, a toggle member 34, and an elastic member 35. The slider 33 is slidably connected to the lead screw 32. When the lead screw 32 rotates, the slider 33 slides relative to the lead screw 32 and the base 1. The toggle member 34 includes a rotating portion 341, and a first end portion 342 and a second end portion 343 located at two opposite sides of the rotating portion 341. The rotating portion 341 is rotatably connected to the slider 33. The first end 342 extends into the slider 33. The second end 343 extends into the locking slot 21 of the sliding seat 2. The elastic member 35 is disposed between the first end 342 and the sliding member 33, and the elastic member 35 is used for maintaining the engagement state of the second end 343 with the card slot 21, so that the sliding seat 2 moves along with the second end 343. When the motor 31 drives the screw rod 32 to rotate, the sliding part 33 drives the sliding seat 2 to slide through the toggle part 34, so that the camera module 4 extends out of or retracts into the base 1.

In this embodiment, when the motor 31 drives the lead screw 32 to rotate in the first direction, the slider 33 slides on the lead screw 32 in the extending direction X1, and the slider 33 drives the sliding seat 2 to slide through the toggle member 34, so that the camera module 4 extends out of the base 1. When the motor 31 drives the lead screw 32 to rotate in a second direction opposite to the first direction, the sliding member 33 slides on the lead screw 32 along a retraction direction X2 opposite to the extension direction X1, and the sliding member 33 drives the sliding seat 2 to slide through the toggle member 34, so that the camera module 4 retracts into the base 1. When functional component 100 the camera module 4 stretches out during base 1, guaranteed camera module 4 and user interaction, when camera module 4 indentation during base 1, reduced the application the use volume of the electronic device 200 of functional component 100, the user of being convenient for carries electronic device 200, consequently functional component 100 has improved user experience.

It is understood that in other embodiments, the camera module 4 may be replaced by other functional devices, including but not limited to any one or more combinations of an iris recognition module, a face recognition module, a flash, a microphone, a receiver, a photoreceptor, a fingerprint module, and a key. The first direction may be a counterclockwise direction or a clockwise direction.

Optionally, the motor 31 may adopt a stepping motor or other servo motor capable of realizing precise control, so as to accurately control the rotation direction and rotation angle of the lead screw 32, thereby precisely controlling the sliding displacement of the sliding seat 2, so that the functional assembly 100 and the electronic device 200 have better use experience and higher reliability.

In one embodiment, as shown in fig. 2 to 4, the extending direction of the lead screw 32 is the same as the sliding direction of the sliding seat 2. The extending direction of the lead screw 32 is parallel to the extending direction X1 and the retracting direction X2 of the slider 33, and therefore the sliding direction of the sliding seat 2 is also parallel to the extending direction X1 and the retracting direction X2 of the slider 33. The extending direction of the slide shoe 2 is the same as the extending direction X1 of the slide member 33. The retraction direction of the slide shoe 2 is the same as the retraction direction X2 of the slider 33.

Alternatively, referring to fig. 2 to 5, the elastic member 35 includes a first sub-elastic member 351 and a second sub-elastic member 352. The first sub-elastic member 351 and the second sub-elastic member 352 are configured to provide elastic forces to the first end portion 342 in opposite directions, such that: when the external force applied to the second end portion 343 is less than or equal to a first threshold, the displacement of the first end portion 342 is less than or equal to a first distance, and the fitting state between the second end portion 343 and the card slot 21 is unchanged; when the external force applied to the second end portion 343 is greater than a second threshold, the displacement of the first end portion 342 is greater than a second distance, and the second end portion 343 is separated from or clamped into the clamping groove 21. Wherein the second threshold is greater than or equal to the first threshold, and the second distance is greater than the first distance. The first distance is small, so that the displacement of the second end portion 343 is also small, and the second end portion 343 can maintain the fitting state with the card slot 21. The second distance is larger, so that the displacement of the second end portion 343 is also larger, the matching relationship between the second end portion 343 and the card slot 21 changes, and the second end portion 343 is separated from or is clamped into the card slot 21 again.

In this embodiment, the first threshold is greater than the friction force between the sliding seat 2 and the base 1, that is, the first threshold is greater than the resistance force received when the sliding seat 2 slides, so when the motor 31 drives the lead screw 32 to slide the sliding member 33, the force applied by the sliding seat 2 on the second end 343 is smaller than the first threshold, the displacement of the first end 342 is smaller than or equal to a first distance, the second end 343 maintains the state of extending into the card slot 21, and the sliding member 33 can drive the sliding seat 2 to move by the toggle member 34, so that the camera module 4 extends or retracts into the base 1 (as shown in fig. 2 and 4).

The second threshold is greater than or equal to the first threshold and is less than the pressing force of the user manually pressing the sliding seat 2 and the impact force of the sliding seat 2 when the sliding seat 2 is impacted toward the base 1, so that when the sliding seat 2 extends out of the base 1, if the user presses the sliding seat 2 or the sliding seat 2 is impacted toward the base 1, the force of the sliding seat 2 acting on the second end 343 is greater than the second threshold, the displacement of the first end 342 is greater than the second distance, the second end 343 disengages from the snap-in groove 21, the sliding seat 2 no longer slides with the toggle member 34, the sliding motion of the sliding member 33 and the sliding motion of the sliding seat 2 are independent of each other, the sliding seat 2 can disengage from the sliding member 33 and retract into the base 1 with the camera module 4 (as shown in fig. 5), thereby avoiding the damage of the camera module 4 caused by rigid impact or manual pressing by a user, and the functional assembly 100 and the electronic device 200 have higher reliability and more diversified use environments.

When the second end 343 is separated from the card slot 21, the motor 31 may drive the lead screw 32 to rotate, so that the slider 33 carries the toggle member 34 to continuously approach the card slot 21 under the driving of the lead screw 32, after the second end 343 abuts against a groove wall of the card slot 21 (such as a first stop block 22 mentioned below), a force of the groove wall of the card slot 21 abutting against the second end 343 is greater than the second threshold, so that the displacement of the first end 342 is greater than the second distance, the second end 343 is snapped into the card slot 21 again (as shown in fig. 2), and the sliding seat 2 can continuously move along with the toggle member 34 in subsequent actions.

It will be appreciated that the second threshold value can be empirically and computationally derived such that the numerical magnitude of the second threshold value is well suited to the function of the functional component 100. When the force applied to the second end portion 343 is greater than the first threshold and smaller than the second threshold, the displacement of the first end portion 342 is greater than the first distance and smaller than the second distance, and at this time, the matching state between the second end portion 343 and the card slot 21 is in a changing process. The setting of the first threshold and the second threshold is realized by the material design and the structural design of the elastic member 35 and the toggle member 34.

Alternatively, the first sub-elastic member 351 and the second sub-elastic member 352 have various matching manners, such as:

in one embodiment, as shown in fig. 3, the sliding member 33 includes a first abutting block 331 and a second abutting block 332 opposite to and spaced apart from each other. The first end 342 is located between the first abutting block 331 and the second abutting block 332. The first sub-elastic member 351 is connected between the first end 342 and the first abutting block 331. The second sub-elastic member 352 is connected between the first end 342 and the second abutting block 332. In this embodiment, when the second end 343 is not subjected to an external force or is subjected to an external force smaller than the first threshold, the first sub elastic member 351 and the second sub elastic member 352 are in the same extended state. For example, the first sub-elastic member 351 and the second sub-elastic member 352 are both compressed, or both stretched.

Wherein, the sliding member 33 further comprises a sliding block 333, and the sliding block 333 is slidably connected with the lead screw 32. The first abutting block 331 and the second abutting block 332 are fixed on one side of the sliding block 333 facing the sliding seat 2. The sliding member 33 further includes a fixing block 335, and the fixing block 335 is fixed to a side of the sliding block 333 facing the sliding seat 2. The fixing block 335 can be fixedly connected to the first abutting block 331 and the second abutting block 332, so as to increase the structural strength of the sliding member 33. The rotating portion 341 of the toggle member 34 is rotatably connected to the fixed block 335. The slider 33 is integrally formed.

In another embodiment, referring to fig. 6, the sliding member 33 includes a holding block 334. The first sub-elastic member 351 and the second sub-elastic member 352 are connected between the abutting block 334 and the first end 342 at intervals, and one of the first sub-elastic member 351 and the second sub-elastic member 352 is compressed and the other is stretched. In other words, one of the first sub-elastic member 351 and the second sub-elastic member 352 provides a pushing force and the other provides a pulling force, so as to cooperate with each other, so that when the second end portion 343 is not subjected to an external force or the external force applied thereto is smaller than the first threshold value, the cooperating state of the second end portion 343 and the card slot 21 is not changed.

Wherein, the sliding member 33 further comprises a sliding block 333, and the sliding block 333 is slidably connected with the lead screw 32. The abutting block 334 is fixed on a side of the sliding block 333 facing the sliding seat 2. The sliding member 33 further includes a fixing block 335, and the fixing block 335 is fixed to a side of the sliding block 333 facing the sliding seat 2. The fixing block 335 may be fixedly connected to the abutting block 334 to increase the structural strength of the sliding member 33. The rotating portion 341 of the toggle member 34 is rotatably connected to the fixed block 335. The slider 33 is integrally formed.

Alternatively, the first sub-elastic member 351 and the second sub-elastic member 352 may have various implementation forms, for example:

in one embodiment, as shown in fig. 3 and 6, the first sub elastic member 351 is a spring. The second sub-elastic member 352 is a spring. The initial lengths (without external force) of the first sub-elastic member 351 and the second sub-elastic member 352 are the same, and the elastic coefficients are the same, so that the material type of the functional component 100 is simplified, a fool-proof design is not required, and the cost of the functional component 100 is reduced.

In another embodiment, referring to fig. 7, the first sub-elastic member 351 and the second sub-elastic member 352 are both rubber members, and the first sub-elastic member 351 and the second sub-elastic member 352 are integrally formed through a connecting member 353. The connecting member 353 may be a rubber member. The first sub-elastic member 351, the second sub-elastic member 352, and the connection member 353 may be integrally formed by in-mold injection.

The connecting member 353 is connected to one end of the first sub-elastic member 351 abutting against the first abutting block 331 and one end of the second sub-elastic member 352 abutting against the second abutting block 332, so as to avoid affecting the compression or stretching action of the first sub-elastic member 351 and the second sub-elastic member 352 abutting against each other. Alternatively, the connecting member 353 is connected to one end of the first sub-elastic member 351 abutting against the abutting block 334 and one end of the second sub-elastic member 352 abutting against the abutting block 334 (not shown in the figure).

Alternatively, referring to fig. 3 and 5, the sliding seat 2 includes a first stop block 22 and a second stop block 23 protruding toward the sliding member 33 and spaced apart from each other. The direction of the first stop block 22 toward the second stop block 23 is the same as the direction of the camera module 4 retracting into the chassis 1 (e.g., the retracting direction X2 of the slider 34). The slot 21 is formed between the first stop block 22 and the second stop block 23. A movable space 24 is formed at a side of the first stop block 22 away from the second stop block 23, and the movable space 24 is used for accommodating the second end 343 away from the card slot 21. When the second end 343 is located in the movable space 24, the sliding motion of the toggle member 34 and the sliding motion of the sliding seat 2 are not interfered with each other.

In this embodiment, when the second end portion 343 extends into the slot 21, the second end portion 343 is located between the first stop block 22 and the second stop block 23. When the second end portion 343 is separated from the card slot 21, the second end portion 343 crosses the first stopper 22 from the card slot 21 and enters the movable space 24. When the second end portion 343 is snapped into the card slot 21, the second end portion 343 crosses the first stop block 22 from the movable space 24 and enters the card slot 21.

Optionally, as shown in fig. 3, the first end surface 221 of the first stop block 22 facing the sliding member 33 is an arc surface. Because the first end surface 221 is an arc surface, the second end portion 343 is separated from the slot 21 or clamped into the slot 21 by the first end surface 221, so that the action is smoother, the resistance is small, and the reliability of the functional component 100 is favorably ensured.

The second end 343 is an arc surface facing the second end 3431 of the base 1. When the toggle member 34 is stationary relative to the slider 33 and the second end 343 is snapped into the slot 21, the second end 3431 and the first end 221 are staggered. When the second end surface 3431 and the first end surface 221 are both arc surfaces, the second end portion 343 slides over the first stopper 22 more smoothly, the resistance is small, and the reliability of the functional component 100 is favorably ensured. Moreover, when the toggle member 34 is stationary relative to the sliding member 33 and the second end 343 is clamped into the clamping groove 21, the second end 3431 is staggered from the first end 221, so that a stable abutting environment is formed between the second end 343 and the first stop block 22, and the reliability of the functional assembly 100 is further ensured. When the toggle member 34 is stationary relative to the sliding member 33 and the second end portion 343 is clamped into the clamping groove 21, a surface of the second end portion 343, which abuts against the first stop block 22, is a plane, and a surface of the first stop block 22, which abuts against the second end portion 343, is also a plane.

Alternatively, as shown in fig. 3, a first distance is formed between a distal end point 3421 of the first end portion 342 far from the rotating portion 341 and the rotation center 3411 of the rotating portion 341, and a second distance is formed between a distal end point 3432 of the second end portion 343 far from the rotating portion 341 and the rotation center 3411 of the rotating portion 341, the second distance being greater than the first distance, so as to reduce a space required for the movement of the first end portion 342, thereby reducing the volume of the sliding member 33. For example, a ratio of the second pitch to the first pitch is 2 or more. Of course, in other embodiments, the second pitch may be less than or equal to the first pitch.

Optionally, referring to fig. 1 and 8, the base 1 includes a bottom plate 11 and a frame 12 connected to a periphery of the bottom plate 11. The bottom plate 11 and the frame 12 enclose a containing cavity 13. The driving assembly 3 is accommodated in the accommodating cavity 13. The frame 12 is provided with a telescopic opening 121 communicated to the accommodating cavity 13. The sliding seat 2 is slidably connected to the frame 12 through the expansion port 121, so that the camera module 4 extends out of or retracts into the accommodating cavity 13 through the expansion port 121. The bottom plate 11 may be a rear cover or a middle partition plate of the electronic device 200. The frame 12 may be a peripheral frame of the electronic device 200.

In this embodiment, the bottom plate 11 of the base 1 supports the sliding seat 2 and the driving component 3, so as to ensure that the driving component 3 can drive the sliding seat 2 to extend and retract relative to the base 1. The frame 12 covers and hides the sliding seat 2 and the driving component 3, so as to improve the appearance and safety of the functional component 100. Because the expansion port 121 is disposed on the frame 12, the camera module 4 extends and contracts at the side of the base 1, that is, the camera module 4 extends and contracts at the side of the electronic device 200, and the camera module 4 does not occupy the front space of the electronic device 200, so as to avoid the limitation of the screen occupation ratio of the electronic device 200.

Wherein, the outer peripheral side wall of the sliding seat 2 is in clearance fit with the inner peripheral side wall of the expansion port 121. At this time, the clearance between the outer peripheral side wall of the sliding seat 2 and the inner peripheral side wall of the expansion port 121 can ensure that the sliding seat 2 can slide smoothly relative to the base 1.

Alternatively, referring to fig. 1 and 8, the bottom plate 11 is provided with a guide groove 111. The guide groove 111 communicates the accommodating cavity 13 and the expansion port 121, and the sliding seat 2 slides along the guide groove 111. The guide groove 111 is used for cooperating with the telescopic opening 121 to define the sliding direction of the sliding seat 2 together, so as to ensure that the camera module 4 smoothly extends out of the accommodating cavity 13 or retracts into the accommodating cavity 13.

A space is formed between an end surface of the guide groove 111 away from the frame 12 and an outer side surface of the frame 12 (i.e., a side surface away from the accommodating cavity 13). The slide holder 2 has a length dimension in the extending direction of the guide groove 111. The ratio of the pitch to the length dimension is 1 or more and 1.1 or less. At this time, the end surface of the guide groove 111 far from the frame 12 can limit the sliding seat 2, limit the depth of the sliding seat 2 extending into the accommodating cavity 13, and prevent the sliding seat 2 from completely falling into the accommodating cavity 13, thereby ensuring the reliability of the functional assembly 100 and the electronic device 200. Moreover, when the functional component 100 is accidentally impacted and the camera module 4 retracts into the base 1, the sliding seat 2 can be protected in a limiting manner.

Optionally, referring to fig. 5, 8 and 9, the sliding seat 2 further includes a base 25 and a baffle 26 fixed on one side of the base 25. The base 25 encloses a device space 27, and the camera module 4 is accommodated in the device space 27. The baffle 26 is perpendicular to the direction of retracting the camera module 4 into the base 1. When the camera module 4 retracts into the accommodating cavity 13, the baffle 26 covers the expansion port 121. The baffle 26 is used to prevent outside moisture and dust from entering the accommodating cavity 13 through the expansion port 121, so as to improve the reliability of the camera module 4 and the electronic device 200. The first stop block 22 and the second stop block 23 are located on a side of the base 25 facing the slider 33.
