DETAILED DESCRIPTION

[0022] The present invention is further described below in conjunction with the accompanying drawings and specific implementation methods. It should be noted that, under the premise of no conflict, the various embodiments or technical features described below can be arbitrarily combined to form a new embodiment.

[0023] It should be noted that all directional indications in the embodiments of the present invention (such as up, down, left, right, front, back, inside, outside, top, bottom...) are only used to explain the relative position relationship between the components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0024] It should also be noted that when an element is referred to as being "fixed on" or "disposed on" another element, the element may be directly on the other element or there may be an intermediate element at the same time. When an element is referred to as being "connected to" another element, it may be directly connected to the other element or there may be an intermediate element at the same time.

[0025] See also Figures 1 to 10A telescopic rotating assembly 10 provided in one embodiment of the present invention includes a fixed member 12 and a movable member 14. The fixed member 12 is provided with a storage space 16. The movable member 14 is telescopically mounted in the storage space 16 so that the movable member 14 can be telescopically mounted relative to the storage space 16. One end of the storage space 16 is an opening communicating with the outside. The movable member 14 can extend out of the storage space 16 or retract into the storage space 16 through the opening. Therefore, when the movable member 14 is needed to be used, the movable member 14 can be extended out of the fixed member 12. When it is not needed, the movable member 14 can be retracted into the fixed member 12. This can reduce the overall volume of the telescopic rotating assembly 10 when not in use, making it convenient for users to carry and store.

[0026] Preferably, the movable member 14 and the fixed member 12 are rotatably matched, and when the movable member 14 extends to the outside of the fixed member 12, the movable member 14 can rotate relative to the fixed member 12, thereby adjusting the relative angle between the movable member 14 and the fixed member 12. It should be noted that the movable member 14 extending to the outside of the fixed member 12 may mean that the movable member 14 extends to the outside of the fixed member 12 as a whole, or that part of the movable member 14 extends to the outside of the fixed member 12, as long as the fixed member 12 does not hinder the rotation of the movable member 14.

[0027] The movable part 14 has a storage state and a use state. In the storage state, the movable part 14 is stored in the storage space 16 and remains relatively fixed with the fixed part 12. In the use state, the movable part 14 extends to the outside of the storage space 16 and rotates a preset angle relative to the fixed part 12.

[0028] The specific application scenario of the telescopic rotating assembly 10 is not limited. In this embodiment, the telescopic rotating assembly 10 is applied to a charger, which can use the movable part 14 to support the electronic device to be charged, and make the electronic device tilted during the charging process, so that the user can view the content displayed on the screen of the electronic device. In other embodiments, the telescopic rotating assembly 10 can also be used for products that have certain requirements for the use angle, such as desktop stands, cameras, etc.

[0029] In one embodiment, the telescopic rotation assembly 10 also includes a driving mechanism 17 disposed between the fixed member 12 and the movable member 14, and the movable member 14 is telescopically mounted in the storage space 16 through the driving mechanism 17. The driving mechanism 17 can drive the movable member 14 to be telescopic relative to the fixed member 12, so that the movable member 14 is extended out of the storage space 16 or retracted into the storage space 16. At the same time, the driving mechanism 17 can drive the movable member 14 to rotate relative to the fixed member 12 when the movable member 14 is extended out of the storage space 16, thereby adjusting the movable member 14 to a desired support angle. By setting up a driving mechanism 17 to drive the movable part 14 to retract and rotate, the user does not need to manually rotate the movable part 14 to adjust the supporting angle of the movable part 14, which is convenient for users to use. In addition, in the process of pushing the movable part 14 back to the storage space 16, the driving mechanism 17 drives the movable part 14 to automatically rotate to the position before rotation. Compared with the user first rotating the movable part 14 back to the position and then pushing the movable part 14 back to the storage space 16, the user only needs to apply a pushing force to the movable part 14 to drive the movable part 14 to rotate back to the position and retract it into the storage space 16, which can avoid the movable part 14 not rotating to the correct position due to improper operation or visual errors, thereby affecting the storage of the movable part 14.

[0030] The driving mechanism 17 drives the movable part 14 to extend and retract relative to the fixed part 12 along a first direction, and drives the movable part 14 to rotate relative to the fixed part 12 along a second direction, and the second direction surrounds the periphery of the first direction, that is, the rotation direction of the movable part 14 surrounds the periphery of the extension and retraction direction of the movable part 14.

[0031] Specifically, the fixed member 12 has a substantially rectangular outline, the storage space 16 extends along the length direction of the fixed member 12 , and the movable member 14 is retractable relative to the fixed member 12 along the length direction of the fixed member 12 .

[0032] The rotation angle of the movable member 14 relative to the fixed member 12 is 30° to 70°. By controlling the rotation angle of the movable member 14 within this range, it is possible to prevent the movable member 14 from rotating too small or too large, that is, to prevent the movable member 14 from tilting too small or too large, thereby preventing the electronic device from tilting too small or too large to affect the user's viewing of the display content of the electronic device. Preferably, the rotation angle of the movable member 14 relative to the fixed member 12 is 50°.

[0033] In one embodiment, the driving mechanism 17 includes a driving member 18 and a guide and limiting structure. The driving member 18 is connected to the movable member 14 to provide power to the movable member 14, driving the movable member 14 to retract and rotate. The guide and limiting structure is arranged between the fixed member 12 and the movable member 14. The guide and limiting structure can form a guiding effect during the retraction and extension of the movable member 14, so that the movable member 14 can run smoothly along a preset direction. At the same time, it can also form a limiting effect after the movable member 14 is extended out of the storage space 16, so that the movable member 14 can switch from the linear motion of retraction relative to the fixed member 12 to the rotation relative to the fixed member 12 under the drive of the driving member 18, so as to adjust the support angle of the movable member 14.

[0034] It is understandable that the specific type of the driving member 18 is not limited, and it can be an electric driving member such as a motor or a cylinder, or an elastic member such as a spring. In the present application, the driving member 18 is an elastic member. When the movable member 14 is stored in the storage space 16, the elastic member is in a compressed state and generates elastic potential energy, which can be used as a driving force to drive the movable member 14 to extend out of the storage space 16 and rotate relative to the fixed member 12. For the convenience of description, the following description takes the driving member 18 as an elastic member 18 as an example, but it does not limit the driving member to only be an elastic member.

[0035] Specifically, the elastic member 18 is a spring, one end of which is connected to the fixed member 12, and the other end is connected to the movable member 14, and the axial direction of the spring is consistent with the expansion and contraction direction of the movable member 14. When the movable member 14 is subjected to an external force and moves into the storage space 16, the movable member 14 will squeeze the spring to cause the spring to contract, and when the external force on the movable member 14 disappears, the spring returns to its initial state and drives the movable member 14 to slide out of the storage space 16.

[0036] The telescopic rotating assembly 10 further includes a locking assembly 20, which has a locked state and an unlocked state. In the locked state, the movable member 14 is stored in the storage space 16 and is relatively fixed to the fixed member 12, that is, the locking assembly 20 locks the movable member 14 and the fixed member 12 so that the two are relatively fixed. In the unlocked state, the movable member 14 can move relative to the fixed member 12, that is, the locking assembly 20 releases the lock so that the movable member 14 can move relative to the fixed member 12. When the movable member 14 is stored in the storage space 16, the locking assembly 20 can be in a locked state, so that the movable member 14 and the fixed member 12 remain relatively fixed, and the movable member 14 is prevented from moving outward under the action of the elastic member 18. When the movable member 14 needs to be used, the locking assembly 20 can be switched from the locked state to the unlocked state to release the relative fixing effect, and the movable member 14 will automatically move in the direction outside the storage space 16 under the action of the elastic member 18.

[0037] The specific manner in which the locking assembly 20 achieves locking and unlocking is not limited, as long as it can switch between the locked state and the unlocked state. For example, the locking assembly 20 can achieve locking and unlocking through a snap structure, a lock tongue and a lock hole.

[0038] In this embodiment, the locking assembly 20 switches between the locked state and the unlocked state by pressing the movable part 14 into the storage space 16. That is, the user can switch the locking assembly 20 from the locked state to the unlocked state, or from the unlocked state to the locked state, by pressing the movable part 14, so that the locking and unlocking operations are simple, that is, one-touch unlocking and locking, which is convenient for users to use. Specifically, the locking assembly 20 is an elastic bead, and the locking assembly 20 includes an elastic clamping claw 201 disposed in the fixed part 12 and a positioning block 203 correspondingly disposed on the movable part 14. The positioning block 203 can move relative to the fixed part 12 together with the movable part 14. The elastic clamping claw 201 is elastic and can selectively clamp or release the positioning block 203. When the elastic clamping claw 201 clamps the positioning block 203, the movable part 14 and the fixed part 12 remain relatively fixed, and the locking assembly 20 is in a locked state. When the elastic clamping claw 201 releases the positioning block 203, the movable part 14 can move relative to the fixed part 12 under the action of the elastic member 18, and the locking assembly 20 is in an unlocked state. It should be noted that the positioning block 203 is connected to the movable part 14, which may also mean that the positioning block 203 is directly connected to the movable part 14, or it may mean that the positioning block 203 is indirectly connected to the movable part 14.

[0039] In one embodiment, the telescopic rotating assembly 10 further includes a sliding member 22, which is slidably mounted to the receiving space 16 of the fixed member 12, the elastic member 18 is located between the sliding member 22 and the fixed member 12, and the movable member 14 is located on the outer side of the sliding member 22, i.e., on the side away from the elastic member 18, and is rotatably connected to the sliding member 22. One end of the elastic member 18 is connected to the sliding member 22, i.e., indirectly connected to the movable member 14 through the sliding member 22, and the other end is connected to the fixed member 12. The sliding member 22 can slide relative to the fixed member 12 under the action of the elastic member 18, and drive the movable member 14 to slide together. When the movable member 14 extends out of the fixed member 12, the movable member 14 rotates relative to the sliding member 22 under the action of the elastic member 18 and the guide limit structure, thereby rotating relative to the fixed member 12.

[0040] Specifically, the positioning block 203 of the locking assembly 20 is fixed on the sliding member 22 , that is, the movable part is indirectly connected to the movable member 14 through the sliding member 22 .

[0041] The movable member 14 includes a main body 24 and a connecting shaft 26 connected to one side of the main body 24. The sliding member 22 is provided with a corresponding shaft hole. The connecting shaft 26 can be movably inserted into the shaft hole so that the connecting shaft 26 is rotatably connected to the sliding member 22. When the main body 24 extends to the outside of the fixed member 12, the main body 24 can rotate relative to the sliding member 22 around the connecting shaft 26.

[0042] The specific position of the connecting shaft 26 is not limited, and it can be located at the end of the main body 24 or at the middle of the main body 24. In this embodiment, the connecting shaft 26 and the shaft hole are respectively located at the end positions of the main body 24 and the sliding member 22.

[0043] A guide rod 30 is provided in the storage space 16. The guide rod 30 is relatively fixed to the fixed member 12. The guide rod 30 extends along the extension direction of the movable member 14. The driving member 18 includes a spring sleeved outside the guide rod 30. The sliding member 22 is slidably sleeved outside the guide rod 30 and connected to the spring. By sliding the sliding member 22 on the outside of the guide rod 30, the guide rod 30 can form a guiding effect during the sliding process of the sliding member 22 relative to the fixed member 12, so that the sliding member 22 and the movable member 14 can run more smoothly when they are extended and retracted relative to the fixed member 12.

[0044] The specific number of the elastic member 18 and the guide rod 30 is not limited, and can be one or more. Figure 4 In the embodiment shown, the number of the elastic member 18 and the guide rod 30 is one, one end of the sliding member 22 is slidably mounted on the guide rod 30, and the elastic member 18 is mounted outside the guide rod 30 and connected to one end of the sliding member 22. Figure 7 In another embodiment shown, the number of guide rods 30 and elastic members 18 are both two, and both ends of the sliding member 22 are slidably mounted on the guide rods 30, respectively. Each elastic member 18 is mounted outside a corresponding guide rod 30, and the two elastic members 18 are respectively connected to the two ends of the sliding member 22. The two elastic members 18 jointly push the sliding member 22 and the movable member 14 to slide, so that the sliding member 22 and the movable member 14 can run more smoothly.

[0045] In one embodiment, the fixing member 12 includes a base 32 and a cover 34. The cover 34 is covered on the base 32 and encloses the base 32 to form a storage space 16. The sliding member 22 and the movable member 14 are movably disposed between the base 32 and the cover 34. The fixing member 12 is configured as the base 32 and the cover 34, which can facilitate the installation of the sliding member 22, the movable member 14, etc.

[0046] The connection method between the base 32 and the cover 34 is not limited, such as snap fit, gluing, mechanical fixation, etc. In this embodiment, the base 32 and the cover 34 are fixed by fasteners such as bolts.

[0047] A guide block 36 is provided on the outer side of the sliding member 22, and a guide groove 38 is provided on the seat body 32 and / or the cover body 34. The guide groove 38 is communicated with the storage space 16 and extends along the telescopic direction of the movable member 14. The guide block 36 can be slidably inserted into the guide groove 38. When the sliding member 22 slides relative to the fixed member 12, the guide block 36 slides in the guide groove 38 to form a guiding effect, so that the sliding member 22 runs more smoothly.

[0048] Preferably, guide blocks 36 are respectively disposed on opposite sides of the sliding member 22 , and guide grooves 38 are correspondingly disposed on opposite sides of the seat body 32 and / or the cover body 34 , and each guide block 36 is inserted into a corresponding guide groove 38 .

[0049] In one embodiment, a first magnetic member 40 is provided on the sliding member 22, and a second magnetic member 42 is provided on the movable member 14. When the movable member 14 is in a storage state, the first magnetic member 40 and the second magnetic member 42 are staggered. When the movable member 14 is in a use state, the first magnetic member 40 and the second magnetic member 42 are arranged opposite to each other. When the first magnetic component 40 and the second magnetic component 42 are arranged in a staggered manner, there is already a magnetic attraction force between the first magnetic component 40 and the second magnetic component 42. During the rotation process of the movable component 14 switching from the storage state to the use state, the first magnetic component 40 and the second magnetic component 42 gradually approach each other, and the magnetic attraction force between the two becomes larger and larger. The magnetic attraction force can assist the movable component 14 to rotate relative to the sliding component 22, so that the movable component 14 can quickly rotate into place, and the first magnetic component 40 and the second magnetic component 42 are arranged relative to each other, that is, the first magnetic component 40 and the second magnetic component 42 are aligned with each other. At this time, the magnetic attraction force between the first magnetic component 40 and the second magnetic component 42 is the largest, and at the same time, it can also enhance the stability of the movable component 14 in the use state and reduce the risk of the movable component 14 rotating under the gravity of the electronic device.

[0050] In one embodiment, the guide and limit structure includes a concave portion 44 and a protrusion 46. The concave portion 44 is disposed inside the fixed member 12 and communicates with the storage space 16. The protrusion 46 is correspondingly disposed outside the movable member 14 and can move with the movable member 14. The protrusion 46 can be slidably inserted into the concave portion 44. When the movable member 14 moves relative to the fixed member 12 under the drive of the elastic member 18, the movable member 14 drives the protrusion 46 to move, so that the protrusion 46 slides in the concave portion 44. The protrusion 46 cooperates with the concave portion 44 to form a guiding and limiting effect.

[0051] The recessed portion 44 includes a guide portion 48 and a limiting portion 50 connected to the guide portion 48. The guide portion 48 extends along the extension direction of the movable member 14. The limiting portion 50 is located at the outer end of the guide portion 48, i.e., the end close to the opening of the storage space 16, and extends obliquely relative to the guide portion 48. After the locking assembly 20 is unlocked, the sliding member 22 and the movable member 14 slide out of the storage space 16 under the action of the elastic member 18. At this time, the protruding portion 46 slides in the guide portion 48 of the recessed portion 44. When the protruding portion 46 moves from the guide portion 48 to the limiting portion 50 under the action of the elastic member 18, the movable member 14 extends to the outside of the storage space 16. Since the limiting portion 50 is inclined relative to the guide portion 48, the protruding portion 46 will be blocked by the inner wall of the limiting portion 50 when sliding in the limiting portion 50, so that the protruding portion 46 is not protruding. With respect to the tilting movement of the movable member 14 in the extension and retraction direction, the movable member 14 will rotate relative to the fixed member 12 under the action of the limiting portion 50 and the protruding portion 46. Therefore, when the movable member 14 is in the storage state, the user only needs to press the movable member 14 inward to switch the locking assembly 20 from the locked state to the unlocked state. The movable member 14 will slide under the action of the elastic member 18, slide to the outside of the fixed member 12 and rotate relative to the fixed member 12. The movable member 14 can be unlocked to the use state in one step, which is convenient for the user. When the movable part 14 is not needed, the user only needs to push the movable part 14 into the storage space 16. The movable part 14 and the sliding part 22 slide into the storage space 16 at the same time and squeeze the elastic part 18. At the same time, the movable part 14 rotates in the opposite direction relative to the fixed part 12 under the action of the protrusion 46 and the limit part 50. After the protrusion 46 enters the guide part 48 from the limit part 50, the movable part 14 stops rotating. The movable part 14 moves into the storage space 16 together with the sliding part 22 until the locking assembly 20 forms a locked state. The movable part 14 can be locked to the storage state in one step, simplifying the user's operation steps.

[0052] It can be understood that when the protrusion 46 is located at the critical position where the guide portion 48 is connected to the limiting portion 50, the main body 24 of the movable member 14 can be just extended to the outside of the fixed member 12, or extended to the outside of the fixed member 12 and spaced a certain distance from the fixed member 12. In the present application, when the protrusion 46 is located at the critical position where the guide portion 48 is connected to the limiting portion 50, the main body 24 of the movable member 14 extends to the outside of the fixed member 12 and spaced a certain distance from the fixed member 12, for example, 1 mm, to prevent the movable member 14 from being interfered by the fixed member 12 during the rotation process.

[0053] The recessed portion 44 further includes a positioning portion 52, which is connected to the limiting portion 50 and is located at one end of the limiting portion 50 away from the guide portion 48. The positioning portion 52 extends along the telescopic direction of the movable member 14, that is, the limiting portion 50 is connected between the guide portion 48 and the positioning portion 52, and the extension direction of the guide portion 48 is the same as the extension direction of the positioning portion 52. When the movable member 14 rotates by a predetermined angle, the protrusion 46 moves from the limiting portion 50 to the positioning portion 52, and the positioning portion 52 can position the protrusion 46 at this position, thereby preventing the movable member 14 from rotating and enhancing the stability of the movable member 14 in use.

[0054] like Figure 8 As shown, in another embodiment, the difference from the above embodiment is that the driving member 18 further includes a torsion spring 53 disposed in the receiving space 16, and the torsion spring 53 is connected to the movable member 14 and the sliding member 22 respectively. When the movable member 14 is received in the receiving space 16, the torsion spring 53 has a certain elastic force. When the movable member 14 is extended out of the receiving space 16, the movable member 14 can rotate relative to the sliding member 22 under the action of the torsion spring 53, thereby driving the movable member 14 to rotate relative to the fixed member 12. Specifically, the torsion spring 53 is sleeved outside the connecting shaft 26 of the movable member 14, and the two ends of the torsion spring 53 are connected to the connecting shaft 26 and the fixed member 12 respectively. When the movable member 14 is received in the receiving space 16, the torsion spring 53 can generate torque, so when the main body 24 of the movable member 14 is extended out of the fixed member 12, the movable member 14 will rotate relative to the fixed member 12 under the action of the torsion spring 53.

[0055] The present invention also provides a charging device 1, comprising a charging body 54 and the telescopic rotating assembly 10 of each of the above embodiments, wherein a fixing member 12 is mounted on the charging body 54, a circuit board is provided inside the charging body 54, a first wireless charging module 56 is provided inside the movable member 14, and the first wireless charging module 56 is electrically connected to the circuit board. Specifically, the fixing member 12 is mounted inside the charging body 54. The charging device 1 can charge an electronic device using the first wireless charging module 56 inside the movable member 14. When in use, the movable member 14 can be extended outside the charging body 54, so that the first wireless charging module 56 follows the movable member 14 to extend outside the charging body 54 and rotate to a preset angle. When the electronic device is placed on the movable member 14, the electronic device can be charged while the user can view the content displayed on the screen of the electronic device. When not in use, the movable member 14 can be stored in the fixing member 12 to reduce the overall volume of the charging device 1, making it convenient to carry and store.

[0056] A conductive member 58 and a conductive connector 60 are provided in the storage space 16 of the fixed member 12. The conductive member 58 is electrically connected to the conductive connector 60 and the first wireless charging module 56 respectively, and the conductive member 58 can move with the movable member 14. The conductive connector 60 is provided in the storage space 16 and remains relatively fixed with the fixed member 12. The circuit board in the charging body 54 is located outside the fixed member 12 and close to the conductive connector 60, and the conductive connector 60 is electrically connected to the circuit board. The conductive member 58 and the conductive connector 60 are slidably matched, and the conductive connector 60 extends along the extension direction of the movable member 14. During the extension and retraction of the movable member 14 relative to the fixed member 12, the conductive member 58 moves with the movable member 14, so that the conductive member 58 slides relative to the conductive connector 60. During the sliding process, the conductive member 58 always keeps in contact with the conductive connector 60, forming an electrical connection effect, and avoiding the electrical connection being affected by the movement of the movable member 14.

[0057] Specifically, the conductive member 58 is installed on the sliding member 22 and is electrically connected to the first wireless charging module 56 in the movable member 14 through a wire. A wire hole is provided on the connecting shaft 26 of the movable member 14 for the wire to pass through and be electrically connected to the first wireless charging module 56.

[0058] A conductive groove is provided on the conductive connector 60, and a conductive member 58, such as a conductive spring sheet, is inserted into the conductive groove. When the sliding member 22 slides relative to the fixed member 12, the conductive member 58 slides in the conductive groove, and the conductive member 58 is tightly pressed on the conductive connector 60 by its own elastic force, thereby ensuring the stability of the electrical connection between the conductive member 58 and the conductive connector 60.

[0059] The charging device 1 also includes a second wireless charging module 62 and a third wireless charging module 64 respectively mounted on the charging body 54. The second wireless charging module 62 and the third wireless charging module 64 are respectively electrically connected to the circuit board. The second wireless charging module 62 is rotatably connected to the charging body 54, and the third wireless charging module is located at the top of the charging body 54. When the second wireless charging module 62 is not in use, the second wireless charging module 62 can be rotated to be stored on the charging body 54. At this time, the charging body 54 and the second wireless charging module 62 form a stacked arrangement effect. The second wireless charging module 62 is located at the top of the charging body 54, and the third wireless charging module 64 is located below the second wireless charging module 62. When the first wireless charging module 56 is in use, it can be extended from one side of the charging body 54. It should be understood that the charging device 1 can be provided with the second wireless charging module 62 and the third wireless charging module 64 at the same time, or only one of them can be provided according to product design requirements.

[0060] The first wireless charging module 56 and the second wireless charging module 62 can both rotate relative to the charging body 54 and adjust the support angle, so they can be used to charge electronic devices that need to watch display content so that the display content can be watched during the charging process, and the third wireless charging module 64 can be used to charge electronic devices that do not need to watch display content. In this embodiment, the first wireless charging module 56 is used to charge smart watches, the second wireless charging module 62 is used to charge mobile phones, and the third wireless charging module 64 is used to charge Bluetooth headsets.

[0061] The above-mentioned embodiments are only preferred embodiments of the present invention and cannot be used to limit the scope of protection of the present invention. Any non-substantial changes and substitutions made by technicians in this field on the basis of the present invention shall fall within the scope of protection required by the present invention.
