[0055] Please see Figure 1 , Figure 2 , Figure 7 and Figure 8 The telescopic flipping device 100 provided in this application will now be described. The telescopic flipping device 100 includes a support shell (not shown), a sliding seat 11, a telescopic drive unit 20, a flipping seat 31, a flipping drive unit 32, and an elastic reset unit 33.

[0056] The sliding seat 11 is slidably mounted on the support shell, and the telescopic drive unit 20 is mounted on the support shell and connected to the sliding seat 11. The telescopic drive unit 20 drives the sliding seat 11 to slide on the support shell, thereby driving the sliding seat 11 to slide out and slide retract on the support shell. It can be understood that the sliding seat 11 slides out and slides retract in opposite directions on the support shell. That is, when the telescopic drive unit 20 drives the sliding seat 11 to slide on the support shell in the extension direction, it pushes the sliding seat 11 to extend; when the telescopic drive unit 20 drives the sliding seat 11 to slide in the opposite direction, that is, when the telescopic drive unit 20 drives the sliding seat 11 to slide on the support shell in the retraction direction, it pushes the sliding seat 11 to retract.

[0057] The flip base 31 is mounted on the sliding base 11, so that when the sliding base 11 slides on the support shell, the flip base 31 can be driven to slide. That is, the flip base 31 extends and retracts with the sliding base 11 on the support shell. The flip base 31 is rotatably mounted on the sliding base 11, so that the flip base 31 can flip and move on the sliding base 11. When this telescopic flip device 100 is applied to an electronic device, when the sliding base 11 drives the flip base 31 to extend out of the body of the electronic device, the flip base 31 can flip and move on the sliding base 11.

[0058] The flipping drive unit 32 includes a first elastic element 321. One end of the first elastic element 321 is connected to the sliding seat 11, and the other end of the first elastic element 321 is connected to the flipping seat 31. The first elastic element 321 is used to elastically drive the flipping seat 31 to flip. Using the first elastic element 321 to drive the flipping seat 31 to flip has low installation accuracy requirements, low fitting accuracy requirements, is easy to assemble, and has low cost.

[0059] The elastic reset unit 33 is mounted on the sliding seat 11. The elastic reset unit 33 is used to unlock the flip seat 31 when the sliding seat 11 slides out of the support shell to a first predetermined position, so that the first elastic element 321 can drive the flip seat 31 to flip. Furthermore, the elastic reset unit 33 is also used to push the flip seat 31 back to its initial position when it slides and retracts along the support shell, so that the flip seat 31 is not scratched during the sliding and retraction of the sliding seat 11. Unlocking the flip seat 31 and resetting it using the elastic reset unit 33 requires low installation and fitting precision, is easy to assemble, and is low in cost. The initial position refers to the position where the flip seat 31 is locked on the sliding seat 11 by the elastic reset unit 33, and is not flipped.

[0060] Compared with the prior art, the telescopic flipping device 100 provided in this application embodiment drives the flipping seat 31 to flip through the first elastic element 321, thereby eliminating the need for precise installation and fitting accuracy, resulting in low requirements for the structural installation and fitting accuracy of the flipping drive unit 32; and the elastic reset unit 33 drives the flipping seat 31 to reset, which also eliminates the need for precise installation and fitting accuracy, resulting in lower installation and fitting accuracy requirements, easier assembly, and lower cost.

[0061] For ease of description, we define the directions as up, down, front, and back. Specifically: the direction in which the sliding seat 11 extends is upward; the direction in which the sliding seat 11 retracts is downward; the rotating seat 31 rotates on the sliding seat 11; the first elastic element 321 causes the rotating seat 31 to rotate forward; and the rotating seat 31 returns to its original position and rotates backward. In other words, the telescopic drive unit 20 drives the sliding seat 11 to extend upward on the support shell and to retract downward on the support shell, i.e., it drives the sliding seat 11 to move up and down. The first elastic element 321 causes the rotating seat 31 to rotate forward, while the elastic reset unit 33 causes the rotating seat 31 to rotate backward and return to its original position.

[0062] In one embodiment, see Figures 1 to 3 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 it to rotate. The rotary motor 24 is mounted on the bracket 23, which is mounted on a support housing. The push block 22 is threaded onto the lead screw 21 and is connected to the sliding seat 11. 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 11 to extend and retract. This telescopic drive unit 20 can precisely control the position of the sliding seat 11. Understandably, the telescopic drive unit 20 can also use linear modules such as linear motors.

[0063] In one embodiment, a guide rod 25 is mounted on the bracket 23, and the push block 22 is slidably mounted 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.

[0064] In one embodiment, a positioning rod 13 is installed on the sliding seat 11, and a buffer spring 12 is fitted on the positioning rod 13. One end of the buffer spring 12 abuts against the sliding seat 11, and the other end of the buffer spring 12 abuts against the push block 22. In this way, the buffer spring 12 can play a buffering and protective role between the push block 22 and the sliding seat 11.

[0065] In one embodiment, a support frame 14 is mounted on the sliding seat 11, one end of the positioning rod 13 is mounted on the support frame 14, and the other end of the positioning rod 13 is mounted on the sliding seat 11 to stably support the positioning rod 13.

[0066] In one embodiment, see Figures 1 to 3 When the flip seat 31 is in its initial position, the angle between the front surface of the flip seat 31 and the sliding extension direction of the sliding seat 11 ranges from -2 degrees to 0 degrees. A 0-degree angle means the front surface of the flip seat 31 is parallel to the sliding extension direction of the sliding seat 11; in this case, the plane containing the front surface of the flip seat 31 can be defined as the first plane. Since the flip seat 31 flips forward, a negative angle between the front surface of the flip seat 31 and the sliding extension direction of the sliding seat 11 means the front surface of the flip seat 31 is located behind the first plane. This ensures that the front surface of the flip seat 31 will not be scratched when the sliding seat 11 moves the flip seat 31 up and down. The front surface of the flip seat 31 refers to the surface on the front side of the flip seat 31 in the flipping direction, and the sliding extension direction of the sliding seat 11 refers to the direction in which the sliding seat 11 slides upwards, also pointing upwards.

[0067] In one embodiment, see Figure 3 , Figure 4 and Figure 7 The flip base 31 has pivots 311 on opposite sides, and the pivots 311 are mounted on the sliding base 11 to rotate the flip base 31 onto the sliding base 11. It can be understood that one end of the flip base 31 may be provided with an arc surface or a round shaft, and a matching round groove may be provided on the sliding base 11 to rotate the flip base 31 onto the sliding base 11.

[0068] In one embodiment, see Figure 3 and Figure 4 The flip seat 31 is provided with a first limiting part 313, and the sliding seat 11 is provided with a first positioning part 1111. When the flip seat 31 flips on the sliding seat 11, it will drive the first limiting part 313 to rotate. When the flip seat 31 rotates to a first set angle, the first positioning part 1111 will contact the first limiting part 313 and stop the first limiting part 313, thereby positioning the flip seat 31 to limit the maximum flip angle of the flip seat 31.

[0069] In one embodiment, the first limiting part 313 may be a protrusion provided on the flip base 31, and the first positioning part 1111 may be a limiting block provided on the sliding base 11. The limiting block stops the protrusion to limit the rotation angle of the flip base 31. It can be understood that the first positioning part 1111 may be a protrusion provided on the sliding base 11, and the first limiting part 313 may be an arc-shaped groove provided on the flip base 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 flip base 31.

[0070] In one embodiment, the first limiting part 313 is a protrusion provided on the pivot 311, and the sliding seat 11 is provided with a first groove 111 corresponding to the position of the protrusion to accommodate the part of the pivot 311 corresponding to the protrusion, and the sidewall of the first groove 111 is the first positioning part 1111.

[0071] In one embodiment, the angle at which the flip seat 31 flips on the sliding seat 11 ranges from 0 degrees to 90 degrees, such as 68 degrees. The specific angle can be set as needed.

[0072] In one embodiment, the first limiting portion 313 may be two protrusions provided on the pivot 311, which define the initial position and the final position of the flipping seat 31 by means of the two sidewalls of the first groove 111 and the two protrusions. It can be understood that the first limiting portion 313 may also be a protrusion provided on the pivot 311, which defines the initial position and the final position of the flipping seat 31 by means of the cooperation between the opposite two sides of the protrusion and the two sidewalls of the first groove 111.

[0073] In one embodiment, see Figure 7 and Figure 8The elastic reset unit 33 includes a pusher 331 and a second elastic member 332. The flip base 31 has a supporting surface 3111. The pusher 331 is slidably mounted on the sliding base 11, and the second elastic member 332 is mounted on the sliding base 11. The pusher 331 is used to push the flip base 31 to rotate and reset, and the second elastic member 332 elastically pushes the pusher 331 towards the flip base 31. The support shell has a first stop structure, which is used to stop the pusher 331 as the sliding base 11 slides out to a first set position on the support shell. When the telescopic drive unit 20 drives the sliding seat 11 to slide and extend to the first set position on the support shell, the first stop structure stops the pushing member 331, keeping the pushing member 331 relatively stationary with respect to the support shell. Meanwhile, the telescopic drive unit 20 drives the sliding seat 11 to continue extending and moving, causing the flip seat 31 to extend and move, causing the pushing member 331 to leave the abutment surface 3111 on the flip seat 31. Under the action of the first elastic member 321, the flip seat 31 flips. When the telescopic drive unit 20 drives the sliding seat 11 to slide and retract on the support shell, the pushing member 331 leaves the first stop structure. Under the elastic force of the second elastic member 332, the pushing member 331 moves towards the abutment surface 3111 of the flip seat 31 and pushes against the abutment surface 3111, thereby pushing the flip seat 31 to rotate and reset. The abutment surface 3111 on the flip seat 31 facilitates the pushing member 331 pushing the flip seat 31 to reset and rotate.

[0074] In one embodiment, the first stop structure may be a first slide rail disposed on the support housing, and a first stop block 3313 is disposed on the pusher 331. The first stop block 3313 extends into the first slide rail, and the first slide rail limits the stroke of the first stop block 3313, thereby limiting the stroke of the pusher 331. It can be understood that the first stop structure may also be a first stop protrusion disposed on the support housing, which stops and limits the first stop block 3313, thereby stopping the movement of the pusher 331.

[0075] In one embodiment, the pusher 331 is provided with a push surface 3311. When the flipping seat 31 is in the initial position, the push surface 3311 is adapted to fit against the abutment surface 3111. The push surface 3311 is provided on the pusher 331 so that when the pusher 331 pushes against the abutment surface 3111, the push surface 3311 can play a certain guiding role, which facilitates pushing the flipping seat 31 to reset and rotate. When the flipping seat 31 is in the initial position, the push surface 3311 and the abutment surface 3111 are adapted to fit against each other. That is to say, after the flipping seat 31 is reset, the push surface 3311 and the abutment surface 3111 are adapted to fit against each other, which can better hold the abutment surface 3111, thereby locking the flipping seat 31 and keeping the flipping seat 31 in the initial position.

[0076] In one embodiment, the abutting surface 3111 can be a plane to facilitate manufacturing. Understandably, the abutting surface 3111 can also be a curved surface.

[0077] In one embodiment, the end of the pushing surface 3311 near the front surface of the flip seat 31 can protrude by about 0.1 mm. This allows the flip seat 31 to transitionally reset when the pushing surface 3311 pushes against the holding surface 3111, ensuring that the angle between the front surface of the flip seat 31 and the sliding extension direction of the sliding seat 11 in the initial position ranges from -2 degrees to 0 degrees. Understandably, when the pushing surface 3311 and the holding surface 3111 are fitted together, the angle between the front surface of the flip seat 31 and the sliding extension direction of the sliding seat 11 can also range from -2 degrees to 0 degrees.

[0078] In one embodiment, the abutment surface 3111 may be disposed on the pivot 311. It is understood that the abutment surface 3111 may also be disposed at the end of the flip seat 31.

[0079] In one embodiment, the second elastic element 332 is a compression spring. When the sliding seat 11 drives the flip seat 31 to extend, and the first stop structure stops and limits the pusher 331, the compression spring is compressed. When the sliding seat 11 drives the flip seat 31 to retract, the compression spring extends to push the pusher 331 towards the flip seat 31. It is understood that the second elastic element 332 can also be a tension spring. When the sliding seat 11 drives the flip seat 31 to extend, and the first stop structure stops and limits the pusher 331, the tension spring is stretched. When the sliding seat 11 drives the flip seat 31 to retract, the tension spring contracts to pull the pusher 331 towards the flip seat 31.

[0080] In one embodiment, the second elastic element 332 is a compression spring. The elastic reset unit 33 further includes a first guide rod 333, which is mounted on the sliding seat 11. The compression spring is sleeved on the first guide rod 333. The pusher 331 has a pushing part 3312, which is slidably mounted on the first guide rod 333. One end of the compression spring elastically abuts against the pushing part 3312, and the other end of the compression spring elastically abuts against the sliding seat 11. The first guide rod 333 is provided to position and guide the compression spring.

[0081] In one embodiment, the elastic reset unit 33 further includes a first support 334, which is mounted on the sliding seat 11. The first support 334 has a first shaft hole 3341, into which the pivot 311 of the flip seat 31 is inserted. The pusher 331 is slidably mounted on the first support 334, and the second elastic member 332 is mounted on the first support 334. By providing the first support 334, when the first support 334 is mounted on the sliding seat 11, the pivot 311 on one side of the flip seat 31 can be rotatably mounted on the sliding seat 11, making installation more convenient and easier to assemble.

[0082] In one embodiment, the first guide rod 333 is mounted on the first support 334. When the first support 334 is mounted on the sliding seat 11, the first guide rod 333 can be fixed on the sliding seat 11, making installation convenient.

[0083] In one embodiment, the flipping drive unit 32 further includes a second support 322, which is mounted on the sliding seat 11. The second support 322 has a second shaft hole 3221, into which the pivot 311 of the flipping seat 31 is inserted. One end of the first elastic member 321 is connected to the second support 322. The first support 334 and the second support 322 are respectively located on opposite sides of the flipping seat 31, so that the pivots 311 on opposite sides of the flipping seat 31 can be inserted into the first shaft hole 3341 and the second shaft hole 3221 respectively, thereby rotatably connecting the flipping seat 31 to the first support 334 and the second support 322. This allows the flipping seat 31 to be rotatably mounted on the sliding seat 11 when the first support 334 and the second support 322 are mounted, facilitating assembly. It is understood that the pivots 311 on opposite sides of the flipping seat 31 can also be directly rotatably connected to the sliding seat 11.

[0084] In one embodiment, the flipping seat 31 is provided with an eccentric portion 312, and the first elastic element 321 is a tension spring. The other end of the tension spring is connected to the eccentric shaft, so that the eccentric portion 312 is elastically pulled by the tension spring to drive the flipping seat 31 to flip. Understandably, the first elastic element 321 can also be a torsion spring.

[0085] In one embodiment, the eccentric portion 312 can be a hook provided on the pivot 311 for connecting a tension spring. Of course, the eccentric portion 312 can also be a hanging hole or other structure provided at other positions on the flip seat 31.

[0086] In the above embodiment, when the flipping drive unit 32 further includes a second support 322, the tension spring is connected to the second support 322, so that when the second support 322 is installed on the sliding seat 11, the tension spring is connected to the sliding seat 11.

[0087] In one embodiment, when the elastic reset unit 33 unlocks the flip seat 31, the first elastic member 321 can drive the flip seat 31 to flip to a set angle, thereby ensuring the positional accuracy of the flip seat 31. For example, when the pusher 331 leaves the abutment surface 3111, the first elastic member 321 can drive the flip seat 31 to flip to a set angle, thereby allowing the flip seat 31 to maintain that angle.

[0088] In one embodiment, multiple flip seats 31 can be provided on the sliding seat 11 to enable the sliding seat 11 to drive multiple flip seats 31 to move synchronously. It is understood that only one flip seat 31 can also be provided on the sliding seat 11. The specific configuration can be adjusted as needed.

[0089] In one embodiment, see Figures 1 to 3 The telescopic flipping device 100 also includes a flipping element 41 and a flipping drive mechanism 42. The flipping element 41 is rotatably mounted on the sliding base 11, and the flipping drive mechanism 42 is mounted on the sliding base 11 to drive the flipping element 41 to flip on the sliding base 11. The flipping element 41 is mounted on the sliding base 11 so that when the sliding base 11 slides on the support shell, it can drive the flipping element 41 to slide; that is, the flipping element 41 extends and retracts with the sliding base 11 on the support shell. The flipping element 41 is rotatably mounted on the sliding base 11, so that the flipping element 41 can flip and move on the sliding base 11. When this telescopic flipping device 100 is applied to an electronic device, when the sliding base 11 drives the flipping element 41 to extend out of the electronic device's body, the flipping element 41 can flip and move on the sliding base 11. The flipping element 41 is provided on the sliding base 11 and can be used in conjunction with the flipping base 31 to form multiple flipping structures on the sliding base 11 for ease of use.

[0090] In one embodiment, see Figure 1 , Figure 9 and Figure 10The flipping component 41 is provided with an eccentric shaft 412. The flipping drive mechanism 42 includes a toggle member 421 and an elastic reset member 422. The toggle member 421 is used to actuate the eccentric shaft 412 when the sliding seat 11 slides out of the support housing at a second predetermined position, thereby causing the flipping component 41 to flip. The elastic reset member 422 is used to elastically push the toggle member 421 to reset the flipping component 41. One end of the elastic reset member 422 is connected to the toggle member 421, and the other end of the elastic reset member 422 is connected to the sliding seat 11. The support housing is provided with a second stop structure; the second stop structure is used to move the stop toggle member 421 as the sliding seat 11 slides out of the support housing at the second predetermined position. When the telescopic drive unit 20 drives the sliding seat 11 to slide and extend to the second set position on the support shell, the second stop structure stops the actuating member 421, keeping the actuating member 421 relatively stationary with respect to the support shell. Meanwhile, the telescopic drive unit 20 drives the sliding seat 11 to continue extending and moving, causing the flipping member 41 to extend and move, thus causing the actuating member 421 to actuate the eccentric shaft 412, thereby causing the flipping member 41 to flip. When the telescopic drive unit 20 drives the sliding seat 11 to slide and retract on the support shell, the elastic reset member 422 elastically pushes the actuating member 421 to move in the same direction as the sliding seat 11, thereby causing the actuating member 421 to actuate the eccentric shaft 412 in the opposite direction, thereby causing the flipping member 41 to rotate and reset. Using the actuating member 421 and the elastic reset member 422 results in a simple structure, low requirements for installation and assembly accuracy, and low cost. Understandably, the flipping drive mechanism 42 can also use a motor, gear and rack mechanism, etc.

[0091] In one embodiment, the first set position and the second set position can be set to the same position, so that the flipping seat 31 and the flipping member 41 can flip simultaneously. Understandably, the first set position and the second set position can be set to different positions, so that the flipping seat 31 and the flipping member 41 can flip at different times.

[0092] In one embodiment, the second stop structure may be a second slide rail disposed on the support housing, and a second stop block 4213 is disposed on the actuating member 421. The second stop block 4213 extends into the second slide rail, thereby limiting the travel of the second stop block 4213 and thus limiting the travel of the actuating member 421. It can be understood that the second stop structure may also be a second stop protrusion disposed on the support housing, which stops and limits the second stop block 4213, thereby stopping the movement of the actuating member 421.

[0093] In one embodiment, the actuating member 421 is provided with a actuating part 4211, which is used for the eccentric shaft 412 to slide into. In this way, when the actuating member 421 moves relative to the flipping member 41, the eccentric shaft 412 can be actuated to drive the flipping member 41 to rotate.

[0094] In one embodiment, the actuating part 4211 is an elongated hole. By inserting the eccentric shaft 412 into the elongated hole, the eccentric shaft 412 is moved by the opposite side walls of the elongated hole, thereby causing the flipping member 41 to rotate. It can be understood that the actuating part 4211 can also be a slotted structure, with the eccentric shaft 412 placed in the slot. The eccentric shaft 412 is moved by the opposite side walls of the slot, thereby causing the flipping member 41 to rotate.

[0095] In one embodiment, the length direction of the actuating part 4211 is perpendicular to the sliding direction of the sliding seat 11. Understandably, the length direction of the actuating part 4211 may also be set to be inclined to the sliding direction of the sliding seat 11.

[0096] In one embodiment, see Figure 5 , Figure 6 and Figure 9 The flipper 41 has a rotating shaft 411 on each of its opposite sides. The rotating shaft 411 is mounted on the sliding seat 11 so that the flipper 41 can be rotatably mounted on the sliding seat 11. It can be understood that one end of the flipper 41 can also be provided with an arc surface or a round shaft, and a matching round groove can be provided on the sliding seat 11 so that the flipper 41 can be rotatably mounted on the sliding seat 11.

[0097] In one embodiment, see Figure 5 and Figure 6 The flipper 41 is provided with a second limiting part 413, and the sliding seat 11 is provided with a second positioning part 1121. When the flipper 41 flips on the sliding seat 11, it will drive the second limiting part 413 to rotate. When the flipper 41 rotates to a second set angle, the second positioning part 1121 will contact the second limiting part 413 and stop the second limiting part 413, thereby positioning the flipper 41 to limit the maximum flipping angle of the flipper 41.

[0098] In one embodiment, the second limiting part 413 may be a protrusion provided on the flipping member 41, and the second positioning part 1121 may be a limiting block provided on the sliding seat 11. The limiting block stops the protrusion, thereby limiting the rotation angle of the flipping member 41. It can be understood that the second positioning part 1121 may be a protrusion provided on the sliding seat 11, and the second limiting part 413 may be an arc-shaped groove provided on the flipping member 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 flipping member 41.

[0099] In one embodiment, the second limiting part 413 is a protrusion provided on the rotating shaft 411, and the sliding seat 11 is provided with a second groove 112 corresponding to the position of the protrusion to accommodate the part of the rotating shaft 411 corresponding to the protrusion, and the sidewall of the second groove 112 is the second positioning part 1121.

[0100] In one embodiment, the angle at which the flipping member 41 flips on the sliding seat 11 ranges from 0 degrees to 90 degrees, such as 68 degrees. The specific angle can be set as needed.

[0101] In one embodiment, the second limiting portion 413 may be two protrusions provided on the rotating shaft 411, which define the initial position and the final position of the flipping member 41 by means of the two sidewalls of the second groove 112 and the two protrusions. It can be understood that the second limiting portion 413 may also be a protrusion provided on the rotating shaft 411, which defines the initial position and the final position of the flipping member 41 by means of the cooperation between the opposite two sides of the protrusion and the two sidewalls of the second groove 112.

[0102] In one embodiment, see Figures 1 to 3 When the flipper 41 is in its initial position, the angle between the front surface of the flipper 41 and the sliding extension direction of the sliding seat 11 ranges from -2 degrees to 0 degrees. A 0-degree angle means the front surface of the flipper 41 is parallel to the sliding extension direction of the sliding seat 11; in this case, the plane containing the front surface of the flipper 41 can be defined as the second plane. Since the flipper 41 flips forward, a negative angle between the front surface of the flipper 41 and the sliding extension direction of the sliding seat 11 means the front surface of the flipper 41 is located behind the second plane. This ensures that the front surface of the flipper 41 will not be scratched when the sliding seat 11 moves the flipper 41 up and down. The front surface of the flipper 41 refers to the surface on the front side of the flipper 41 in the flipping direction, and the sliding extension direction of the sliding seat 11 refers to the direction in which the sliding seat 11 slides upwards, also pointing upwards.

[0103] In one embodiment, the elastic reset member 422 is a compression spring. When the sliding seat 11 causes the flipping member 41 to extend, and the second stop structure stops and limits the actuating member 421, the compression spring is compressed. When the sliding seat 11 causes the flipping member 41 to retract, the compression spring extends to push the actuating member 421 towards the flipping member 41. It is understood that the elastic reset member 422 can also be a tension spring. When the sliding seat 11 causes the flipping member 41 to extend, and the second stop structure stops and limits the actuating member 421, the tension spring is stretched. When the sliding seat 11 causes the flipping member 41 to retract, the tension spring contracts to pull the actuating member 421 towards the flipping member 41.

[0104] In one embodiment, the flipping drive mechanism 42 further includes a second guide rod 423, which is mounted on the sliding seat 11. A compression spring is sleeved on the second guide rod 423. The actuating member 421 has a supporting portion 4212, which is slidably mounted on the second guide rod 423. One end of the compression spring elastically abuts against the supporting portion 4212, and the other end of the compression spring elastically abuts against the sliding seat 11. The second guide rod 423 is provided to position and guide the compression spring.

[0105] In one embodiment, the flipping drive mechanism 42 further includes a first support base 424, which is mounted on the sliding base 11. The first support base 424 has a first support hole (not shown). The rotating shaft 411 of the flipping member 41 is inserted into the first support hole. The actuating member 421 is slidably mounted on the first support base 424, and the elastic reset member 422 is mounted on the first support base 424. By providing the first support base 424, when the first support base 424 is mounted on the sliding base 11, the rotating shaft 411 on one side of the flipping member 41 can be rotatably mounted on the sliding base 11, making installation more convenient and easier to assemble.

[0106] In one embodiment, the second guide rod 423 is mounted on the first support base 424. When the first support base 424 is mounted on the sliding base 11, the second guide rod 423 can be fixed on the sliding base 11, making installation convenient.

[0107] In one embodiment, the telescopic flipping device 100 further includes a second support base 43, which is mounted on the sliding base 11. The second support base 43 has a second support hole 431, into which the rotating shaft 411 of the flipping member 41 is inserted. The first support base 424 and the second support base 43 are respectively located on opposite sides of the flipping member 41, so that the rotating shafts 411 on opposite sides of the flipping member 41 can be inserted into the first support hole and the second support hole 431 respectively, thereby rotatably connecting the flipping member 41 to the first support base 424 and the second support base 43. This allows the flipping member 41 to be rotatably mounted on the sliding base 11 when the first support base 424 and the second support base 43 are mounted, facilitating assembly. It is understood that the rotating shafts 411 on opposite sides of the flipping member 41 can also be directly rotatably connected to the sliding base 11.

[0108] In one embodiment, a camera 51a is installed on the flip base 31 so that the telescopic flip device 100 can have a camera function, forming a telescopic flip camera device.

[0109] In one embodiment, a camera 51b may also be provided on the flipping member 41 so that the telescopic flipping device 100 can have multiple cameras 51.

[0110] In one embodiment, when the elastic reset unit 33 unlocks the flip seat 31, the first elastic element 321 can cause the flip seat 31 to flip to a set angle. The telescopic drive unit 20 can drive the sliding seat 11 and the flip member 41 to move relative to the actuating element 421, so that the actuating element 421 causes the flip member 41 to flip, and controls the flip angle of the flip member 41. This allows for precise positioning of the flip seat 31 while controlling the flip angle of the flip member 41.

[0111] In one embodiment, when a camera 51a is mounted on the flip base 31 and a camera 51b is mounted on the flip member 41, the elastic reset unit 33 unlocks the flip base 31. The first elastic member 321 can then rotate the flip base 31 to a set angle, thereby holding the camera 51a at that angle. The telescopic drive unit 20 can drive the sliding base 11 and the flip member 41 to move relative to the actuating member 421, so that the actuating member 421 rotates the flip member 41 and controls the rotation angle of the flip member 41, thereby controlling the rotation angle of the camera 51b.

[0112] Please see Figure 1 and Figure 11 This application also provides an electronic device 1000, including a body 52 and a telescopic flipping device 100 as described in the above embodiments. A camera 51a is mounted on a flipping base 31. When the sliding seat 11 of the telescopic flipping device 100 extends and retracts, the camera 51a can extend out of and retract into the body 52, thus achieving the extension and retraction of the camera 51a. When the flipping base 31 flips and moves on the sliding seat 11, it can flip the camera 51a to adjust its shooting angle. This electronic device 1000 also possesses the technical effects of the telescopic flipping device 100 described above, which will not be elaborated further here.

[0113] In one embodiment, when the telescopic flipping device 100 includes a flipping member 41, a camera 51b can also be installed on the flipping member 41, thereby realizing a structure in which multiple cameras 51 are installed on the sliding seat 11, and the flipping member 41 and the flipping seat 31 can respectively drive the corresponding camera 51 to flip and capture different areas.

[0114] In one embodiment, the camera 51a on the flip base 31 and the camera 51b on the flip member 41 may use the same type of camera 51 or different types of cameras 51.

[0115] In one embodiment, the housing of the telescopic flipping device 100 can be the body 52 of the electronic device 1000. Understandably, the housing can also be provided separately and then mounted on the body 52.

[0116] In one embodiment, the electronic device 1000 can be a desktop learning machine. Of course, the electronic device 1000 can also be a tablet learning machine. The electronic device 1000 can also be a tablet computer, smartphone, etc.

[0117] The above description is merely an optional embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
