Description

Technical Field

[0001] This application belongs to the field of electronic equipment technology, and more specifically, relates to a telescopic flipping device and an electronic device. Background Technology

[0002] Currently, learning terminals on the market, such as tablets and smart speakers with screens, often feature retractable and flip-up camera modules to create a "smart eye" function. These terminals typically have a dual-camera setup: one camera captures the desktop, and the other captures the user's image for video recording. This necessitates a retractable and flip-up device with dual flip-up seats. These devices generally fall into two categories: The first type uses a telescopic drive unit to extend and retract the flip-up seats, while motors on the sides of each seat drive their respective flipping motion. The second type uses a motor on the side of one flip-up seat to drive its flipping motion, and the other uses a telescopic drive unit in conjunction with a rack and pinion mechanism to drive the flip-up seat's rotation. However, requiring a separate motor to drive the flip-up seats is costly and inconvenient to control. Summary of the Invention

[0060] Please see Figure 1 , Figure 3 and Figure 6 The telescopic flipping device 100 provided in this application will now be described. The telescopic flipping device 100 includes a support shell 11, a sliding seat 12, a telescopic drive unit 20, a first flipping seat 31, a second flipping seat 41, a first elastic element 32, a second elastic element 42, and a flipping control unit 50.

[0061] The sliding seat 12 is slidably mounted on the support shell 11. The telescopic drive unit 20 is mounted on the support shell 11 and connected to the sliding seat 12. The telescopic drive unit 20 drives the sliding seat 12 to slide on the support shell 11, thereby driving the sliding seat 12 to slide out and slide retract on the support shell 11. It can be understood that the sliding seat 12 slides out and slides retract in opposite directions on the support shell 11. That is, when the telescopic drive unit 20 drives the sliding seat 12 to slide on the support shell 11 in the extension direction, it pushes the sliding seat 12 to extend; when the telescopic drive unit 20 drives the sliding seat 12 to slide in the opposite direction, that is, when the telescopic drive unit 20 drives the sliding seat 12 to slide on the support shell 11 in the retraction direction, it pushes the sliding seat 12 to retract.

[0062] The first flip-up seat 31 is mounted on the sliding seat 12, so that when the sliding seat 12 slides on the support shell 11, the first flip-up seat 31 can slide. That is, the first flip-up seat 31 extends and retracts with the sliding seat 12 on the support shell 11. The first flip-up seat 31 is rotatably mounted on the sliding seat 12, so that the first flip-up seat 31 can flip and move on the sliding seat 12. For example, when this telescopic flip-up device 100 is applied to an electronic device, when the sliding seat 12 drives the first flip-up seat 31 to extend out of the body of the electronic device, the first flip-up seat 31 can flip and move on the sliding seat 12.

[0063] The second flip-up seat 41 is mounted on the sliding seat 12, so that when the sliding seat 12 slides on the support housing 11, the second flip-up seat 41 can slide. That is, the second flip-up seat 41 extends and retracts with the sliding seat 12 on the support housing 11. The second flip-up seat 41 is rotatably mounted on the sliding seat 12, so that the second flip-up seat 41 can flip and move on the sliding seat 12. For example, when this telescopic flip-up device 100 is applied to an electronic device, when the sliding seat 12 drives the second flip-up seat 41 to extend out of the body of the electronic device, the second flip-up seat 41 can flip and move on the sliding seat 12.

[0064] One end of the first elastic element 32 is connected to the sliding seat 12, and the other end is connected to the first flip seat 31. The first elastic element 32 is used to elastically drive the first flip seat 31 to reset and rotate. That is, the first elastic element 32 applies an elastic force to the first flip seat 31 in the opposite direction to the flipping of the first flip seat 31. In this way, when the first flip seat 31 is not subjected to external force, the first elastic element 32 can drive the first flip seat 31 to the initial position of flipping. Using the first elastic element 32 to drive the first flip seat 31 to reset and rotate has low installation accuracy requirements, low fitting accuracy requirements, is easy to assemble, and has low cost.

[0065] One end of the second elastic element 42 is connected to the sliding seat 12, and the other end is connected to the second flip seat 41. The second elastic element 42 is used to elastically drive the second flip seat 41 to flip. That is, the second elastic element 42 applies an elastic force to the second flip seat 41 in the same direction as the flipping of the second flip seat 41. Thus, when the second flip seat 41 is not subjected to external force, the second elastic element 42 can drive the second flip seat 41 to flip. Using the second elastic element 42 to drive the second flip seat 41 to flip has low installation accuracy requirements, low fitting accuracy requirements, is easy to assemble, and has low cost.

[0066] The flip control unit 50 includes a drive shaft 51 and a drive assembly 52. ​​The drive assembly 52 is mounted on the sliding seat 12. The drive assembly 52 is used to drive the drive shaft 51 to rotate under the drive of the telescopic drive unit 20 when the sliding seat 12 slides out of the support shell 11 to a set position. In other words, the telescopic drive unit 20 drives the sliding seat 12 to cause the first flip seat 31, the second flip seat 41 and the flip control unit 50 to slide out. When the sliding seat 12 extends to the set position, the telescopic drive unit 20 continues to drive the sliding seat 12 to slide on the support shell 11. If the telescopic drive unit 20 continues to drive the sliding seat 12 to slide out, the drive assembly 52 will drive the drive shaft 51 to rotate forward. After the sliding seat 12 extends and moves, if the telescopic drive unit 20 drives the sliding seat 12 to slide and retract, the drive assembly 52 will drive the drive shaft 51 to rotate in reverse until the sliding seat 12 reaches the set position. Then the drive assembly 52 and the drive shaft 51 remain relatively stationary, and the telescopic drive unit 20 can drive the sliding seat 12 to continue to slide and retract.

[0067] The drive shaft 51 is connected to the first flipping seat 31 and the second flipping seat 41 at its two ends, respectively. The drive shaft 51 is configured such that: when rotating forward, it releases the second flipping seat 41 and drives the first flipping seat 31 to flip; when rotating in reverse, it releases the second flipping seat 41 and drives the first flipping seat 31 to reset to its initial position. In other words, for the first flipping seat 31, when rotating forward, the drive shaft 51 can overcome the force of the first elastic element 32 to drive the first flipping seat 31 to flip (i.e., rotate forward); when rotating in reverse, the drive shaft 51 can release the first flipping seat 31, allowing it to rotate in the opposite direction under the action of the first elastic element 32 to reset to its initial position. This achieves control over the flipping and resetting of the first flipping seat 31 and the second flipping seat 41, eliminating the need for a separate motor, thus reducing cost and simplifying the structure.

[0068] Compared with the prior art, the telescopic flipping device 100 provided in this application embodiment uses a first elastic member 32 to elastically drive the first flipping seat 31 to reset and rotate, and a second elastic member 42 to elastically drive the second flipping seat 41 to flip. A drive shaft 51 and a drive assembly 52 are provided. The drive assembly 52 drives the drive shaft 51 to rotate under the drive of the telescopic drive unit 20. When the drive shaft 51 rotates forward, it releases the second flipping seat 41, causing the second elastic member 42 to drive the second flipping seat 41 to flip, and the drive shaft 51 drives the first flipping seat 31 to flip. When the drive shaft 51 rotates in reverse, it releases the first flipping seat 31, causing the first elastic member 32 to reset the first flipping seat 31, and the drive shaft 51 drives the second flipping seat 41 to flip and reset to its initial position. Therefore, no additional motor is required, simplifying the structure, reducing costs, and only requiring control of the telescopic drive unit 20, making control simple.

[0069] For ease of description, the direction of the sliding seat 12's sliding extension is defined as the upward direction, and the direction of the sliding seat 12's sliding retraction is defined as the downward direction. That is, the telescopic drive unit 20 drives the sliding seat 12 to extend upward on the support shell 11 and drives the sliding seat 12 to retract downward on the support shell 11, i.e., drives the sliding seat 12 to move up and down. The direction of the drive shaft 51's forward rotation, the direction of the first flipping seat 31's flipping, and the direction of the second elastic element 42's rotation of the second flipping seat 41 are the same; this forward rotation direction is defined as forward rotation. The direction of the drive shaft 51's reverse rotation, the direction of the first flipping seat 31's reset rotation, and the direction of the second flipping seat 41's reset rotation are the same; this reverse rotation direction is defined as backward rotation. Therefore, the drive shaft 51 drives the first flipping seat 31 to flip forward, the second elastic element 42 drives the second flipping seat 41 to flip forward, the first elastic element 32 drives the first flipping seat 31 to rotate backward and reset, and the drive shaft 51 drives the second flipping seat 41 to rotate backward and reset.

[0070] In one embodiment, see Figure 1 , Figure 3 and Figure 6 The telescopic drive unit 20 includes a lead screw 21, a push block 22, a bracket 23, and a rotary motor 24. The lead screw 21 is rotatably mounted on the bracket 23. The rotary motor 24 is connected to the lead screw 21 to drive its rotation. The rotary motor 24 is mounted on the bracket 23, which is mounted on the support housing 11. The push block 22 is threaded onto the lead screw 21 and is connected to the sliding seat 12. Thus, the rotary motor 24 drives the lead screw 21 to rotate, pushing the push block 22 to move on the lead screw 21, thereby pushing the sliding seat 12 to extend and retract. This telescopic drive unit 20 can precisely control the position of the sliding seat 12. Understandably, the telescopic drive unit 20 can also use a linear module such as a linear motor.

[0071] In one embodiment, a guide rod 25 is installed on the bracket 23, and the push block 22 is slidably installed on the guide rod 25. The guide rod 25 guides the push block 22 to move, so as to ensure that the push block 22 moves smoothly.

[0072] In one embodiment, a positioning rod 13 is installed on the sliding seat 12, and a buffer spring 14 is fitted on the positioning rod 13. One end of the buffer spring 14 abuts against the sliding seat 12, and the other end of the buffer spring 14 abuts against the push block 22. In this way, the buffer spring 14 can play a buffering and protective role between the push block 22 and the sliding seat 12.

[0073] In one embodiment, a support frame 15 is mounted on the sliding seat 12, one end of the positioning rod 13 is mounted on the support frame 15, and the other end of the positioning rod 13 is mounted on the sliding seat 12 to stably support the positioning rod 13.

[0074] In one embodiment, see Figure 1 and Figure 3 When the first flipping seat 31 is in the initial position, the angle between the front surface of the first flipping seat 31 and the sliding extension direction of the sliding seat 12 ranges from -2 degrees to 0 degrees. A 0-degree angle between the front surface of the first flipping seat 31 and the sliding extension direction of the sliding seat 12 means that the front surface of the first flipping seat 31 is parallel to the sliding extension direction of the sliding seat 12. In this case, the plane containing the front surface of the first flipping seat 31 can be defined as the first plane. Since the first flipping seat 31 flips forward, a negative angle between the front surface of the first flipping seat 31 and the sliding extension direction of the sliding seat 12 means that the front surface of the first flipping seat 31 is located behind the first plane. This ensures that the front surface of the first flipping seat 31 will not be scratched when the sliding seat 12 moves the first flipping seat 31 up and down. The front surface of the first flipping seat 31 refers to the surface on the front side of the flipping direction of the first flipping seat 31, and the sliding extension direction of the sliding seat 12 refers to the direction in which the sliding seat 12 slides upwards, also pointing upwards.

[0075] In one embodiment, see Figure 1 and Figure 3When the second flip seat 41 is in its initial position, the angle between the front surface of the second flip seat 41 and the sliding extension direction of the sliding seat 12 ranges from -2 degrees to 0 degrees. A 0-degree angle means the front surface of the second flip seat 41 is parallel to the sliding extension direction of the sliding seat 12; in this case, the plane containing the front surface of the second flip seat 41 can be defined as the second plane. Since the second flip seat 41 flips forward, a negative angle between the front surface of the second flip seat 41 and the sliding extension direction of the sliding seat 12 means the front surface of the second flip seat 41 is located behind the second plane. This ensures that the front surface of the second flip seat 41 will not be scratched when the sliding seat 12 moves the second flip seat 41 up and down. The front surface of the second flip seat 41 refers to the surface on the front side of the flip direction, and the sliding extension direction of the sliding seat 12 refers to the direction in which the sliding seat 12 slides upwards, also pointing upwards.

[0076] In one embodiment, see Figures 6 to 9 The first flip base 31 has a first pivot 311 on each of its opposite sides. The first pivot 311 is mounted on the sliding base 12 so as to rotatably mount the first flip base 31 on the sliding base 12. It can be understood that one end of the first flip base 31 can also be provided with an arc surface or a round shaft, and a matching round groove can be provided on the sliding base 12 so as to rotatably mount the first flip base 31 on the sliding base 12.

[0077] In one embodiment, see Figures 6 to 9 The second flip base 41 has a second pivot 411 on each of its opposite sides. The second pivot 411 is mounted on the sliding base 12 to rotatably mount the second flip base 41 on the sliding base 12. It can be understood that one end of the second flip base 41 may be provided with an arc surface or a round shaft, and a matching round groove may be provided on the sliding base 12 to rotatably mount the second flip base 41 on the sliding base 12.

[0078] In one embodiment, see Figure 4 , Figures 6 to 9One end of the drive shaft 51 is connected to the first flip seat 31 via a first connecting structure 53. The first connecting structure 53 includes a first bushing 531 and a first shaft head 532. The first bushing 531 has a first shaft hole 5310, and the first shaft head 532 can be inserted into the first shaft hole 5310. The first shaft head 532 has a first front side surface 5321 and a first rear side surface 5322. The first front side surface 5321 and the first rear side surface 5322 are arranged along the forward rotation direction of the drive shaft 51, and the first rear side surface 5322 is located behind the first front side surface 5321 along the forward rotation direction of the drive shaft 51. The first shaft hole 5310 has a first front wall surface 5311 and a first rear wall surface 5312. The first front wall surface 5311 and the first rear wall surface 5312 are arranged along the forward rotation direction of the drive shaft 51, and the first rear wall surface 5312 is located behind the first front wall surface 5311 along the forward rotation direction of the drive shaft 51. One of the first shaft head 532 and the first shaft sleeve 531 is connected to the drive shaft 51, and the other of the first shaft head 532 and the first shaft sleeve 531 is connected to the first flip seat 31. When the first flip seat 31 is in the initial position, there is a first gap space 561 between the first front side surface 5321 and the first front wall surface 5311. Thus, when the drive shaft 51 starts to rotate forward, the first front side surface 5321 and the first front wall surface 5311 approach each other, while the first flip seat 31 can remain in the initial position under the action of the first elastic member 32. The drive shaft 51 will release the second flip seat 41, causing the second flip seat 41 to flip to adjust its angle. After the first front side surface 5321 contacts the first front wall surface 5311, the drive shaft 51 continues to rotate forward, which will cause the first flip seat 31 to flip. When the drive shaft 51 reverses, before the first front side 5321 separates from the first front wall surface 5311, the drive shaft 51 releases the first flip seat 31, and the first elastic element 32 drives the first flip seat 31 to reverse and reset until the first flip seat 31 is reset to the starting position and the first front side 5321 separates from the first front wall surface 5311.

[0079] In one embodiment, a first shaft head 532 is disposed on a drive shaft 51, and a first bushing 531 is disposed on a first tilting seat 31. For example, the first shaft head 532 can be disposed on the drive shaft 51, and the first bushing 531 can be disposed on the first tilting seat 31; that is, the first shaft head 532 and the drive shaft 51 are integrally formed, and the first bushing 531 and the first tilting seat 31 are integrally formed. When the first bushing 531 and the first tilting seat 31 are integrally formed, a first shaft hole 5310 can be provided on the first tilting seat 31, so that the portion of the first tilting seat 31 with the first shaft hole 5310 forms the first bushing 531. Alternatively, the first shaft head 532 and the first bushing 531 can be manufactured separately, with the first shaft head 532 connected to the drive shaft 51 and the first bushing 531 connected to the first tilting seat 31.

[0080] Understandably, the first shaft head 532 is disposed on the first tilting seat 31, and the first bushing 531 is disposed on the drive shaft 51. For example, the first shaft head 532 can be disposed on the first tilting seat 31, and the first bushing 531 can be disposed on the drive shaft 51; that is, the first shaft head 532 and the first tilting seat 31 are integrally formed, and the first bushing 531 and the drive shaft 51 are integrally formed. When the first bushing 531 and the drive shaft 51 are integrally formed, a first shaft hole 5310 can be provided on the drive shaft 51, so that the portion of the drive shaft 51 with the first shaft hole 5310 forms the first bushing 531. Of course, the first shaft head 532 and the first bushing 531 can also be manufactured separately, with the first shaft head 532 connected to the first tilting seat 31, and the first bushing 531 connected to the drive shaft 51.

[0081] In one embodiment, when the first flip base 31 is in the initial position, there is a gap space 562 between the first rear side surface 5322 and the first rear wall surface 5312. This ensures that the drive shaft 51 does not exert force on the first flip base 31 when it is in the initial position. The first flip base 31 is held in the initial position by the action of the first elastic member 32, so that when the sliding base 12 drives the first flip base 31 to extend and slide, it will not scratch the first flip base 31 or the devices on the first flip base 31. It can be understood that when the first flip base 31 is in the initial position, the first rear side surface 5322 and the first rear wall surface 5312 can also be in contact.

[0082] In one embodiment, see Figure 5 , Figures 6 to 9The other end of the drive shaft 51 is connected to the second flip seat 41 via a second connecting structure 54. The second connecting structure 54 includes a second bushing 541 and a second shaft head 542. The second bushing 541 has a second shaft hole 5410, and the second shaft head 542 can be inserted into the second shaft hole 5410. The second shaft head 542 has a second front side surface 5421 and a second rear side surface 5422. The second front side surface 5421 and the second rear side surface 5422 are arranged along the forward rotation direction of the drive shaft 51, and the second rear side surface 5422 is located behind the second front side surface 5421 along the forward rotation direction of the drive shaft 51. The second shaft hole 5410 has a second front wall surface 5411 and a second rear wall surface 5412. The second front wall surface 5411 and the second rear wall surface 5412 are arranged along the forward rotation direction of the drive shaft 51, and the second rear wall surface 5412 is located behind the second front wall surface 5411 along the forward rotation direction of the drive shaft 51. One of the second shaft head 542 and the second shaft sleeve 541 is connected to the drive shaft 51, and the other of the second shaft head 542 and the second shaft sleeve 541 is connected to the second flip seat 41. When the second flip seat 41 is in the initial position, the second rear side surface 5422 abuts against the second rear wall surface 5412, thereby keeping the second flip seat 41 in the initial position by the force of the drive shaft 51, so that when the sliding seat 12 drives the second flip seat 41 to extend and retract, it will not scratch the second flip seat 41 and the devices on the second flip seat 41. When the drive shaft 51 starts to rotate forward, the second rear side surface 5422 shares with the second rear wall surface 5412 to release the second flip seat 41. Under the action of the second elastic member 42, the second flip seat 41 is driven to rotate forward and flip, so that the second rear side surface 5422 and the second rear wall surface 5412 remain abutting. When the drive shaft 51 reverses, the interaction between the second rear side surface 5422 and the second rear wall surface 5412 will drive the second flip seat 41 to reverse and reset.

[0083] In one embodiment, the second shaft head 542 is disposed on the drive shaft 51, and the second bushing 541 is disposed on the second tilting seat 41. For example, the second shaft head 542 can be disposed on the drive shaft 51, and the second bushing 541 can be disposed on the second tilting seat 41; that is, the second shaft head 542 and the drive shaft 51 are integrally formed, and the second bushing 541 and the second tilting seat 41 are integrally formed. When the second bushing 541 and the second tilting seat 41 are integrally formed, a second shaft hole 5410 can be provided on the second tilting seat 41, so that the portion of the second tilting seat 41 with the second shaft hole 5410 forms the second bushing 541. Alternatively, the second shaft head 542 and the second bushing 541 can be manufactured separately, with the second shaft head 542 connected to the drive shaft 51 and the second bushing 541 connected to the second tilting seat 41.

[0084] Understandably, the second shaft head 542 is disposed on the second tilting seat 41, and the second shaft sleeve 541 is disposed on the drive shaft 51. For example, the second shaft head 542 can be disposed on the second tilting seat 41, and the second shaft sleeve 541 can be disposed on the drive shaft 51; that is, the second shaft head 542 and the second tilting seat 41 are integrally formed, and the second shaft sleeve 541 and the drive shaft 51 are integrally formed. When the second shaft sleeve 541 and the drive shaft 51 are integrally formed, a second shaft hole 5410 can be provided on the drive shaft 51, so that the portion of the drive shaft 51 with the second shaft hole 5410 forms the second shaft sleeve 541. Of course, the second shaft head 542 and the second shaft sleeve 541 can also be manufactured separately, with the second shaft head 542 connected to the second tilting seat 41, and the second shaft sleeve 541 connected to the drive shaft 51.

[0085] In one embodiment, when the second flip seat 41 is in its initial position, there is a second gap space 563 between the second front side surface 5421 and the second front wall surface 5411. Thus, when the drive shaft 51 begins to rotate forward, the second front side surface 5421 and the second front wall surface 5411 move closer together, and the second flip seat 41 rotates forward under the action of the second elastic member 42. This continues until the second flip seat 41 rotates to a set angle, at which point the second rear side surface 5422 separates from the second rear wall surface 5412. At this point, the drive shaft 51 continues to rotate forward, the second front side surface 5421 and the second front wall surface 5411 move closer together, and the second flip seat 41 remains stationary. The drive shaft 51 can then drive the first flip seat 31 to rotate, thereby adjusting only the angle of the first flip seat 31. When the drive shaft 51 reverses, before the second rear side surface 5422 contacts the second rear wall surface 5412, it only drives the first flip seat 31 to reverse and reset. When the second rear side surface 5422 contacts the second rear wall surface 5412, the drive shaft 51 continues to reverse. The drive shaft 51 will overcome the force of the second elastic element 42 and drive the second flip seat 41 to reverse and reset until the second flip seat 41 is reset to the initial position.

[0086] With the above structure, before the first front side surface 5321 contacts the first front wall surface 5311, regardless of whether the drive shaft 51 rotates forward or backward, the first flipping seat 31 is in the initial position under the action of the first elastic member 32. The drive shaft 51 cooperates with the second elastic member 42 to drive only the second flipping seat 41 to rotate, thereby adjusting the angle of the second flipping seat 41. After the second flipping seat 41 flips to the set angle and the second rear side surface 5422 separates from the second rear wall surface 5412, regardless of whether the drive shaft 51 rotates forward or backward, the drive shaft 51 cooperates with the first elastic member 32 to drive only the first flipping seat 31 to rotate, thereby adjusting the angle of the first flipping seat 31.

[0087] In one embodiment, see Figure 4The first shaft head 532 has a fan-shaped cross-section, and the first front side surface 5321 and the first rear side surface 5322 are the two sides of the fan-shaped first shaft head 532. The first shaft hole 5310 has a fan-shaped cross-section, and the first front wall surface 5311 and the first rear wall surface 5312 are the two sides of the fan-shaped first shaft hole 5310. By setting the first shaft head 532 and the first shaft hole 5310 to be fan-shaped, the dimensions of the first shaft head 532 and the first bushing 531 can be made smaller, while ensuring good structural strength of the first shaft head 532 and the first bushing 531.

[0088] In one embodiment, see Figure 10 A first stop 5313 can be provided in the first bushing 531, and a first arc-shaped groove 5323 can be provided on the side of the first shaft head 532. The first stop 5313 extends into the first arc-shaped groove 5323, and the two sides of the first arc-shaped groove 5323 are the first front side 5321 and the first rear side 5322, respectively. The two opposite sides of the first stop 5313 along the circumference of the first shaft head 532 are the first front wall surface 5311 and the first rear wall surface 5312, respectively.

[0089] In one embodiment, see Figure 11 A first arc-shaped groove 5314 can be provided on the inner wall of the first bushing 531, and a first protrusion 5324 can be provided on the side of the first shaft head 532. The first protrusion 5324 extends into the first arc-shaped groove 5314, and the two opposite sides of the first protrusion 5324 along the circumference of the first shaft head 532 are the first front side 5321 and the first rear side 5322, respectively. The two sides of the first arc-shaped groove 5314 are the first front wall surface 5311 and the first rear wall surface 5312, respectively.

[0090] In one embodiment, see Figure 5 The second shaft head 542 has a fan-shaped cross-section, and the second front side surface 5421 and the second rear side surface 5422 are the two sides of the fan-shaped second shaft head 542. The second shaft hole 5410 has a fan-shaped cross-section, and the second front wall surface 5411 and the second rear wall surface 5412 are the two sides of the fan-shaped second shaft hole 5410. By setting the second shaft head 542 and the second shaft hole 5410 to be fan-shaped, the dimensions of the second shaft head 542 and the second shaft sleeve 541 can be made smaller, while ensuring good structural strength of the second shaft head 542 and the second shaft sleeve 541.

[0091] In one embodiment, see Figure 12A second stop 5413 can be provided in the second bushing 541, and a second arc-shaped groove 5423 is provided on the side of the second shaft head 542. The second stop 5413 extends into the second arc-shaped groove 5423, and the two sides of the second arc-shaped groove 5423 are the second front side 5421 and the second rear side 5422, respectively. The two opposite sides of the second stop 5413 along the circumference of the second shaft head 542 are the second front wall surface 5411 and the second rear wall surface 5412, respectively.

[0092] In one embodiment, see Figure 13 A second arc-shaped groove 5414 can be provided on the inner wall of the second bushing 541, and a second protrusion 5424 can be provided on the side of the second shaft head 542. The second protrusion 5424 extends into the second arc-shaped groove 5414, and the two opposite sides of the second protrusion 5424 along the circumference of the second shaft head 542 are the second front side 5421 and the second rear side 5422, respectively. The two sides of the second arc-shaped groove 5414 are the second front wall surface 5411 and the second rear wall surface 5412, respectively.

[0093] In one embodiment, see Figure 4 , Figure 7 and Figure 9 The first flipping seat 31 is provided with a first positioning part 313, and the sliding seat 12 is provided with a first limiting part 1211. When the first flipping seat 31 flips on the sliding seat 12, it will drive the first positioning part 313 to rotate. When the first flipping seat 31 rotates to a first set angle, the first limiting part 1211 will contact the first positioning part 313 and stop the first positioning part 313, thereby positioning the first flipping seat 31 to limit the maximum flipping angle of the first flipping seat 31.

[0094] In one embodiment, the first positioning part 313 may be a positioning block provided on the first flip seat 31, and the first limiting part 1211 may be a limiting block provided on the sliding seat 12. The limiting block stops the positioning block to limit the rotation angle of the first flip seat 31. It can be understood that the first limiting part 1211 may be a protrusion provided on the sliding seat 12, and the first positioning part 313 may be an arc-shaped groove provided on the first flip seat 31. The protrusion is inserted into the arc-shaped groove to limit the rotation angle of the protrusion in the arc-shaped groove, thereby limiting the rotation angle of the first flip seat 31.

[0095] In one embodiment, the first positioning part 313 is a positioning block provided on the first pivot 311, and the sliding seat 12 is provided with a first groove 121 corresponding to the position of the positioning block to accommodate the part of the first pivot 311 corresponding to the positioning block, and the sidewall of the first groove 121 is the first limiting part 1211.

[0096] In one embodiment, the first flip seat 31 flips on the sliding seat 12 at an angle ranging from 0 degrees to 90 degrees, such as 68 degrees. The specific angle can be set as needed.

[0097] In one embodiment, see Figure 5 , Figure 6 and Figure 8 The second flipping seat 41 is provided with a second positioning part 413, and the sliding seat 12 is provided with a second limiting part 1221. When the second flipping seat 41 flips on the sliding seat 12, it will drive the second positioning part 413 to rotate. When the second flipping seat 41 rotates to a second set angle, the second limiting part 1221 will contact the second positioning part 413 and stop the second positioning part 413, thereby positioning the second flipping seat 41 to limit the maximum flipping angle of the second flipping seat 41.

[0098] In one embodiment, the second positioning part 413 may be a positioning block provided on the second flip seat 41, and the second limiting part 1221 may be a limiting block provided on the sliding seat 12. The limiting block stops the positioning block to limit the rotation angle of the second flip seat 41. It can be understood that the second limiting part 1221 may be a protrusion provided on the sliding seat 12, and the second positioning part 413 may be an arc-shaped groove provided on the second flip seat 41. The protrusion extends into the arc-shaped groove to limit the rotation angle of the protrusion in the arc-shaped groove, thereby limiting the rotation angle of the second flip seat 41.

[0099] In one embodiment, the second positioning part 413 is a positioning block provided on the second pivot 411, and the sliding seat 12 is provided with a second groove 122 corresponding to the position of the positioning block to accommodate the part of the second pivot 411 corresponding to the positioning block, and the sidewall of the second groove 122 is the second limiting part 1221.

[0100] In one embodiment, the angle range of the second flip seat 41 flipping on the sliding seat 12 is 0 degrees to 90 degrees, such as 68 degrees. The specific angle can be set as needed.

[0101] In one embodiment, see Figures 6 to 9The drive shaft 51 has external teeth 511 on its circumferential surface, thus forming a gear structure. The drive assembly 52 includes a rack 521 and an elastic reset member 522. The elastic reset member 522 is mounted on the sliding seat 12, and the rack 521 is slidably mounted on the sliding seat 12. The rack 521 meshes with the external teeth 511, and the elastic reset member 522 applies a force to the rack 521 in the direction of sliding extension of the sliding seat 12. The support housing 11 is provided with a stop structure 111, which is used to stop the rack 521 as the sliding seat 12 slides out of the support housing 11 when the sliding seat 12 slides out of the support housing 11 to a set position. When the telescopic drive unit 20 drives the sliding seat 12 to slide and extend to a set position on the support shell 11, the stop structure 111 stops the rack 521, keeping the rack 521 relatively stationary with respect to the support shell 11. The telescopic drive unit 20 then drives the sliding seat 12 to continue extending, causing the drive shaft 51 to extend as well. The rack 521 moves relative to the drive shaft 51 in the direction of sliding contraction, thus causing the drive shaft 51 to rotate clockwise. Conversely, when the telescopic drive unit 20 drives the sliding seat 12 to retract, it causes the drive shaft 51 to move in the direction of sliding contraction. Under the action of the elastic reset member 522, the rack 521 remains stationary with respect to the stop structure 111, and moves relative to the drive shaft 51 in the direction of sliding extension until the stop structure 111 separates from the rack 521, at which point the drive shaft 51 and rack 521 remain relatively stationary. This structure facilitates control of the rotation angle of the drive shaft 51, thereby controlling the rotation angles of the first flip seat 31 and the second flip seat 41.

[0102] Understandably, an eccentric part can be provided on the drive shaft 51, and the drive assembly 52 uses an elastic actuating element. The elastic actuating element is moved by the telescopic drive unit 20 to actuate the drive shaft 51 to rotate.

[0103] In one embodiment, the stop structure 111 may be a slide rail provided on the support housing 11, and a baffle 5212 is provided on the rack 521. The baffle 5212 extends into the slide rail, and the slide rail limits the stroke of the baffle 5212, thereby limiting the stroke of the rack 521. It can be understood that the stop structure 111 may also be a stop protrusion provided on the support housing 11, which stops and limits the baffle 5212, thereby stopping the movement of the rack 521.

[0104] In one embodiment, the elastic reset member 522 is a compression spring. When the sliding seat 12 drives the drive shaft 51 to move along the sliding extension direction of the sliding seat 12, the stop structure 111 stops and limits the rack 521, and the elastic reset member 522 is compressed. When the sliding seat 12 drives the drive shaft 51 to move along the sliding contraction direction, the elastic reset member 522 extends to push the rack 521 and drive the drive shaft 51 to reverse. Understandably, the elastic reset member 522 can also be a tension spring. When the sliding seat 12 drives the drive shaft 51 to move along the sliding extension direction, the stop structure 111 stops and limits the rack 521, and the tension spring is stretched. When the sliding seat 12 drives the drive shaft 51 to move along the sliding contraction direction, the tension spring contracts to pull the rack 521 and drive the drive shaft 51 to reverse.

[0105] In one embodiment, the drive assembly 52 further includes a guide rod 523, which is slidably mounted on the sliding seat 12. An elastic reset member 522 is a compression spring, sleeved on the guide rod 523. The guide rod 523 is connected to a rack 521, which has a pushing portion 5211. One end of the elastic reset member 522 elastically abuts against the pushing portion 5211, and the other end elastically abuts against the sliding seat 12. The guide rod 523 is provided to position and guide the elastic reset member 522.

[0106] In one embodiment, see Figures 6 to 9 The flip control unit 50 also includes a support base 55, which is mounted on the sliding base 12 and supported by the sliding base 12. The support base 55 has a guide channel 551 extending along the sliding direction of the sliding base 12. A rack 521 is slidably placed in the guide channel 551, and an elastic reset member 522 is also placed in the guide channel 551. The support base 55 is provided to support the rack 521 and the elastic reset member 522, and to guide the rack 521 to move so that it can be mounted on the sliding base 12.

[0107] In one embodiment, see Figures 6 to 9 In one embodiment, the first flipping seat 31 is provided with a first eccentric portion 312, and the first elastic element 32 is a tension spring. The other end of the tension spring is connected to the first eccentric portion 312, so that the first eccentric portion 312 is elastically pulled by the tension spring to drive the first flipping seat 31 to flip. It can be understood that the first elastic element 32 can also be a torsion spring.

[0108] In one embodiment, the first eccentric portion 312 may be a hook disposed on the first pivot 311 for connecting a tension spring. Of course, the first eccentric portion 312 may also be a hanging hole or other structure disposed at other positions on the first flip seat 31.

[0109] In one embodiment, see Figures 6 to 9 In one embodiment, the second flipping seat 41 is provided with a second eccentric portion 412, and the second elastic element 42 is a tension spring. The other end of the tension spring is connected to the second eccentric portion 412, so that the second eccentric portion 412 is elastically pulled by the tension spring to drive the second flipping seat 41 to flip. It can be understood that the second elastic element 42 can also be a torsion spring.

[0110] In one embodiment, the second eccentric portion 412 may be a hook disposed on the second pivot 411 for connecting a tension spring. Alternatively, the second eccentric portion 412 may be a hanging hole or other structure disposed at other locations on the second flip seat 41.

[0111] In one embodiment, the telescopic flipping device 100 further includes a first bearing 33, which is mounted on the sliding seat 12. The first pivot 311 of the first flipping seat 31 is connected to the first bearing 33, and the first pivot 311 is supported by the first bearing 33. In this way, when the first bearing 33 is mounted on the sliding seat 12, the first pivot 311 can be rotatably mounted on the sliding seat 12, which facilitates assembly.

[0112] In one embodiment, the telescopic flipping device 100 further includes a second bearing 411, which is mounted on the sliding seat 12. The second pivot 411 of the second flipping seat 41 is connected to the second bearing 411, and the second pivot 411 is supported by the second bearing 411. Thus, when the second bearing 411 is mounted on the sliding seat 12, the second pivot 411 can be rotatably mounted on the sliding seat 12, which facilitates assembly.

[0113] In one embodiment, the flip control unit 50 includes a support base 55. When the drive shaft 51 is rotatably mounted on the support base 55, since both ends of the drive shaft 51 are connected to the first flip seat 31 and the second flip seat 41 respectively, the support base 55 can be positioned between the first flip seat 31 and the second flip seat 41. The first shaft seat 33 is located on the side of the first flip seat 31 away from the support base 55. The first shaft seat 33 cooperates with the support base 55 to support the first flip seat 31, so that the first flip seat 31 can be rotatably mounted on the sliding seat 12. It can be understood that the first shaft seat 33 can also be provided on both sides of the first flip seat 31 to support the first flip seat 31.

[0114] Similarly, in one embodiment, the flip control unit 50 includes a support base 55. When the drive shaft 51 is rotatably mounted on the support base 55, since both ends of the drive shaft 51 are connected to the first flip seat 31 and the second flip seat 41 respectively, the support base 55 can be positioned between the first flip seat 31 and the second flip seat 41. The second shaft seat 411 is positioned on the side of the second flip seat 41 away from the support base 55. The second shaft seat 411 cooperates with the support base 55 to support the second flip seat 41, so that the second flip seat 41 can be rotatably mounted on the sliding seat 12. It can be understood that first shaft seats 33 can also be provided on both sides of the second flip seat 41 to support the second flip seat 41.

[0115] In one embodiment, a first camera 611 is mounted on the first flip base 31 and a second camera 612 is mounted on the second flip base 41, so as to drive the two cameras 61 to extend, retract and flip, forming a dual-camera telescopic flip structure.

[0116] Please see Figure 1 and Figure 14 This application also provides an electronic device 1000, including a body 62 and a telescopic flipping device 100 as described in the above embodiments. A first flipping base 31 is equipped with a first camera 611, and a second flipping base 41 is equipped with a second camera 612.
