[0029] In one embodiment, Figure 1 As shown, a rotating shaft is provided, which includes a first connecting member 10, a second connecting member 20, a motorized member 30 and a positioning member 40; the first connecting member 10 is sleeved outside the second connecting member 20, and the positioning member 40 is sleeved outside the first connecting member 10; the first end of the first connecting member 10 has at least one protrusion 11 and at least one first recessed portion 12 along the length direction of the first connecting member 10; the first end of the second connecting member 20 has at least one pair of second recessed portions 21 away from the first connecting member 10; the pair of second recessed portions 21 are recessed in the first recessed portions 12 In the space; wherein, the protrusion 11, the first recessed portion 12, the pair of second recessed portions 21 and the positioning component 40 form a pair of accommodating cavities 50, the accommodating cavity 50 accommodates the motor component 30, and the size of the accommodating cavity 50 decreases along the rotation direction of the first connecting member 10 or the second connecting member 20; when the second connecting member 20 rotates, the narrow end 51 of the target accommodating cavity in the pair of accommodating cavities 50 moves toward the motor component 30 to jam the motor component 30; the target accommodating cavity is the space in the pair of accommodating cavities 50, the direction in which the space size decreases is opposite to the rotation direction of the second connecting member 20.

[0030] In the embodiment of this application, Figure 2 As shown, Figure 2 The first connecting member 10 is sleeved outside the second connecting member 20, and the positioning member 40 is sleeved outside the first connecting member 10. A receiving cavity 50 is formed between the first connecting member 10, the second connecting member 20 and the positioning member 40. The motorized member 30 is placed in the receiving cavity 50, and the assembly can be completed as shown in FIG. Figure 1 The shaft shown.

[0031] The two connectors of the rotating shaft (a first connector 10 and a second connector 20) can be connected to a driver and an object, respectively. The driver can drive the connector connected to the driver to rotate, and the connector connected to the driver drives the connector connected to the object to rotate, thereby driving the object to rotate. The following example uses the first connector 10 of the rotating shaft connected to the driver and the second connector 20 connected to the object. In this case, the second connector 20 will rotate when the object shakes, while the first connector 10 will rotate only when driven by the driver. The object can be a display screen.

[0032] The shape of the motorized component 30 can be a sphere or a cylinder.

[0033] like Figure 3 As shown, the first connector 10 has at least one protrusion 11 and at least one first recess 12 along its length. The first end of the second connector 20 has at least one pair of second recesses 21 facing away from the first connector 10; the pair of second recesses 21 are located within the recessed space of the first recess 12.

[0034] In one possible implementation, the first connecting member 10 has a protrusion 11 along the length direction, thereby forming a first recessed portion 12; the first end of the second connecting member 20 has a pair of second recessed portions 21 facing away from the first connecting member 10, and the pair of second recessed portions 21 are within the recessed space of the first recessed portion 12.

[0035] like Figure 4 As shown, a protrusion 11 , a first recess 12 , a pair of second recesses 21 and a positioning component 40 form a pair of accommodating cavities 50 , which include an accommodating cavity 501 and an accommodating cavity 502 , and the motor component 30 is accommodated in the accommodating cavity 501 and the accommodating cavity 502 .

[0036] The size of the accommodating cavity 50 decreases along the rotation direction of the first connecting member 10 or the second connecting member 20, and the end with the smaller space is the narrow end of the accommodating cavity 50; the size of a pair of accommodating cavities 50 decreases in opposite directions, that is, the size of the accommodating cavity 501 and the accommodating cavity 502 decreases in opposite directions.

[0037] When the second connecting member 20 rotates, the narrow end 51 of the target accommodating cavity in the pair of accommodating cavities 50 moves toward the motor component 30 to lock the motor component 30; the target accommodating cavity is the space in the pair of accommodating cavities 50 whose space size decreases in the direction opposite to the rotation direction of the second connecting member 20.

[0038] For example, the second connecting member 20 is as follows Figure 4 When rotating in the direction indicated by the middle arrow, the space of the accommodating cavity 501 decreases in the opposite direction of the rotation of the second connecting member 20, indicating that the accommodating cavity 501 is the target accommodating cavity. At this point, the narrow end of the accommodating cavity 501 moves toward the maneuvering member 30 in the accommodating cavity 501. The maneuvering member 30 in the accommodating cavity 501 engages the narrow end of the accommodating cavity 501, thereby locking the second connecting portion 20 and the positioning member 40, thus locking the rotating shaft, preventing the second connecting member 20 from rotating further and, in turn, preventing the connected object from shaking.

[0039] The second connecting member 20 is as follows Figure 5When rotating in the direction indicated by the middle arrow, the space of the accommodating cavity 502 decreases in the direction opposite to the rotation direction of the second connecting member 20, i.e., the accommodating cavity 502 becomes the target accommodating cavity. At this time, the narrow end of the accommodating cavity 502 moves toward the maneuvering member 30 in the accommodating cavity 502. The maneuvering member 30 in the accommodating cavity 502 engages the narrow end of the accommodating cavity 502, thereby locking the second connecting portion 20 and the positioning member 40, thus locking the rotating shaft, preventing the second connecting member 20 from rotating further, and thus preventing the connected object from shaking.

[0040] In one possible implementation, the first connecting member 10 has two spaced protrusions 11, and two first recessed portions 12 are formed between the two spaced protrusions 11; the first end of the second connecting member 20 has two pairs of second recessed portions 21, and the two pairs of second recessed portions 21 are respectively located in the recessed spaces of the two first recessed portions 12.

[0041] like Figure 6 As shown, two protrusions 11, two first recesses 12, two pairs of second recesses 21 and the positioning component 40 form two pairs of accommodating cavities 50, one pair of accommodating cavities 50 includes an accommodating cavity 501 and an accommodating cavity 502, and one pair of accommodating cavities 50 includes an accommodating cavity 503 and an accommodating cavity 504, and the accommodating cavities 501, accommodating cavity 502, accommodating cavity 503 and accommodating cavity 504 accommodate the motor component 30.

[0042] The sizes of the accommodating cavity 501 and the accommodating cavity 502 decrease in opposite directions; the sizes of the accommodating cavity 503 and the accommodating cavity 504 decrease in opposite directions.

[0043] When the second connecting member 20 rotates, the narrow end 51 of the target accommodating cavity in each pair of accommodating cavities 50 moves toward the motor component 30 to lock the motor component 30; the target accommodating cavity is the space in each pair of accommodating cavities 50 whose space size decreases in the direction opposite to the rotation direction of the second connecting member 20.

[0044] For example, the second connecting member 20 is as follows Figure 6 When rotating in the direction indicated by the middle arrow, the spatial size of the accommodating chamber 501 and the accommodating chamber 503 decreases in the opposite direction of the rotation of the second connecting member 20, that is, the accommodating chamber 501 and the accommodating chamber 503 are the target accommodating chambers. At this time, the narrow end of the accommodating chamber 501 moves toward the maneuvering member 30 in the accommodating chamber 501, and the narrow end of the accommodating chamber 503 moves toward the maneuvering member 30 in the accommodating chamber 503. The maneuvering member 30 in the accommodating chamber 501 is locked into the narrow end of the receiving chamber 501, and the maneuvering member 30 in the accommodating chamber 503 is locked into the narrow end of the receiving chamber 503, thereby locking the second connecting portion 20 and the positioning member 40, achieving a locking of the rotating shaft, preventing the second connecting member 20 from continuing to rotate, and thus preventing the fixedly connected object from shaking.

[0045] The second connecting member 20 is as follows Figure 7 When rotating in the direction indicated by the middle arrow, the space size of the accommodating chamber 502 and the accommodating chamber 504 decreases in the opposite direction of the rotation of the second connecting member 20, that is, the accommodating chamber 502 and the accommodating chamber 504 are the target accommodating chambers. At this time, the narrow end of the accommodating chamber 502 moves toward the maneuvering member 30 in the accommodating chamber 502, and the narrow end of the accommodating chamber 504 moves toward the maneuvering member 30 in the accommodating chamber 504. The maneuvering member 30 in the accommodating chamber 502 is locked into the narrow end of the accommodating chamber 502, and the maneuvering member 30 in the accommodating chamber 504 is locked into the narrow end of the accommodating chamber 504, thereby locking the second connecting portion 20 and the positioning member 40, achieving a locked rotation axis, preventing the second connecting member 20 from further rotating, and thus preventing the fixedly connected object from shaking.

[0046] The rotating shaft provided in the embodiment of the present application includes a first connecting member, a second connecting member, a movable component and a positioning component; the first connecting member is sleeved outside the second connecting member, and the positioning component is sleeved outside the first connecting member; the first end of the first connecting member has at least one protrusion and at least one first recess along the length direction of the first connecting member; the first end of the second connecting member has at least one pair of second recesses facing away from the first connecting member; the pair of second recesses are located in the recessed space of the first recess; wherein the protrusion, the first recess, the pair of second recesses and the positioning component form a pair of accommodating cavities, the accommodating cavities accommodate the movable component, and the size of the accommodating cavities decreases along the rotation direction of the first connecting member or the second connecting member; when the second connecting member rotates, the narrow end of the target accommodating cavity in the pair of accommodating cavities, the direction of space size reduction of which is opposite to the rotation direction of the second connecting member, moves toward the movable component, and the movable component in the target accommodating cavity is stuck in the narrow end of the target accommodating cavity, thereby locking the second connecting member and the positioning component, thereby locking the rotating shaft, preventing the second connecting member from continuing to rotate, and thereby preventing the object fixedly connected to the second connecting member from shaking. The rotating shaft structure provided in the embodiment of the present application is simple, the parts do not require high processing accuracy, the rotating shaft structure is not restricted by processing accuracy, the locking success rate is high, and the processing cost is low.

[0047] In one embodiment, when the first connecting member 10 rotates, the protrusion 11 drives the movable part 30 in the first accommodating cavity of a pair of accommodating cavities 50 and the second connecting member 20 to rotate in turn, and the wide end 52 in the second accommodating cavity of a pair of accommodating cavities 50 moves toward the movable part 30 in the second accommodating cavity; the first accommodating cavity is a space in a pair of accommodating cavities 50 in which the direction of space size reduction is opposite to the direction of rotation of the first connecting member 10, and the second accommodating cavity is a space in a pair of accommodating cavities 50 in which the direction of space size reduction is the same as the direction of rotation of the first connecting member 10.

[0048] In the embodiment of the present application, the rotating shaft should have the function of locking when the object to which it is fixed is shaken, and should also have the function of normal rotation.

[0049] In a possible implementation, the rotating shaft has a pair of accommodating cavities 50 , namely, an accommodating cavity 501 and an accommodating cavity 502 .

[0050] When the first connecting member 10 is pressed Figure 8 When rotating in the direction indicated by the middle arrow, the space size of accommodating chamber 501 decreases in the opposite direction of the rotation of first connecting member 10, meaning accommodating chamber 501 becomes the first accommodating chamber. The space size of accommodating chamber 502 decreases in the same direction as the rotation of first connecting member 10, meaning accommodating chamber 502 becomes the second accommodating chamber. At this time, protrusion 11 rotates toward the motorized component 30 in accommodating chamber 501 in the direction indicated by the arrow, thereby driving the motorized component 30 in accommodating chamber 501 to move in the same direction until the motorized component 30 in accommodating chamber 501 contacts the second connecting member 20, thereby driving the second connecting member 20 to rotate. Due to the rotation direction of first connecting member 10, the wide section 52 in accommodating chamber 502 continuously rotates toward the motorized component 30 in accommodating chamber 502. Even if the motorized component in accommodating chamber 502 falls into the narrow end of accommodating chamber 502 at certain rotational positions due to gravity or other factors, it will not become stuck there, thus ensuring normal rotation of the shaft.

[0051] When the first connecting member 10 is pressed Figure 9 When rotating in the direction indicated by the middle arrow, the direction in which the space size of the accommodating chamber 502 decreases is opposite to the direction in which the first connecting member 10 rotates, that is, the accommodating chamber 502 is the first accommodating chamber; the direction in which the space size of the accommodating chamber 501 decreases is the same as the direction in which the first connecting member 10 rotates, that is, the accommodating chamber 501 is the second accommodating chamber. At this time, the protrusion 11 rotates toward the maneuverable component 30 in the accommodating chamber 502 in the direction of the arrow, thereby driving the maneuverable component 30 in the accommodating chamber 502 to move in the direction of the arrow until the maneuverable component 30 in the accommodating chamber 502 contacts the second connecting member 20 and drives the second connecting member 20 to rotate. Due to the rotation direction of the first connecting member 10, the wide section 52 in the accommodating chamber 501 keeps rotating toward the maneuverable component 30 in the accommodating chamber 501, even if the maneuverable component in the accommodating chamber 501 is at certain rotation positions (for example Figure 9 The rotating shaft 500 may fall into the narrow end of the accommodating cavity 501 due to gravity or other reasons, and will not get stuck at the narrow end, thereby achieving normal rotation of the rotating shaft.

[0052] In a possible implementation, the rotating shaft has two pairs of accommodating cavities 50 , that is, one pair of accommodating cavities 50 is an accommodating cavity 501 and an accommodating cavity 502 , and one pair of accommodating cavities 50 is an accommodating cavity 503 and an accommodating cavity 504 .

[0053] When the first connecting member 10 is pressed Figure 10When rotating in the direction indicated by the middle arrow, the space size of accommodating chambers 501 and 503 decreases in the opposite direction of the rotation of first connector 10, meaning accommodating chambers 501 and 503 become first accommodating chambers. The space size of accommodating chambers 502 and 504 decreases in the same direction as the rotation of first connector 10, meaning accommodating chambers 502 and 504 become second accommodating chambers. At this point, the two protrusions 11 rotate in the directions of the arrows toward the maneuverable components 30 in accommodating chambers 501 and 503, respectively, thereby driving the maneuverable components 30 in accommodating chambers 501 and 503 to move in the same directions until the maneuverable component 30 in accommodating chamber 501 contacts the second connector 20 and simultaneously contacts the maneuverable component 30 in accommodating chamber 503, thereby jointly driving the second connector 20 to rotate. Due to the rotation direction of the first connecting member 10, the wide sections 52 in the accommodating chamber 502 and the accommodating chamber 504 always rotate toward the motorized components 30 in their respective cavities. Even if the motorized components in the accommodating chamber 502 or the accommodating chamber 504 fall into the narrow end of the accommodating chamber 502 or the accommodating chamber 504 (for example, Figure 10 The position of the motor component 30 in the middle accommodating cavity 504) will not be stuck at the narrow end, thereby achieving normal rotation of the shaft.

[0054] When the first connecting member 10 is pressed Figure 11 When rotating in the direction indicated by the middle arrow, the space size of accommodating chambers 502 and 504 decreases in the opposite direction to the rotation direction of first connector 10, meaning accommodating chambers 502 and 504 become first accommodating chambers. The space size of accommodating chambers 501 and 503 decreases in the same direction as the rotation direction of first connector 10, meaning accommodating chambers 501 and 503 become second accommodating chambers. At this point, the two protrusions 11 rotate in the directions of the arrows toward the motorized components 30 in accommodating chambers 502 and 504, respectively, thereby driving the motorized components 30 in accommodating chambers 502 and 504 to move in the same directions until the motorized components 30 in accommodating chamber 502 contact the second connector 20, and simultaneously the motorized components 30 in accommodating chamber 504 contact the second connector 20, thereby jointly driving the second connector 20 to rotate. Due to the rotation direction of the first connecting member 10, the wide sections 52 in the accommodating chamber 501 and the accommodating chamber 503 always rotate toward the motorized components 30 in their respective cavities. Even if the motorized components in the accommodating chamber 501 or the accommodating chamber 503 fall into the narrow end of the accommodating chamber 501 or the accommodating chamber 503 (for example, Figure 10 The position of the motor component 30 in the middle accommodating cavity 501) will not be stuck at the narrow end, thereby achieving normal rotation of the shaft.

[0055] When the first connector of the rotating shaft provided in the embodiment of the present application rotates, the protrusion sequentially drives the motorized components in the first accommodating cavity, whose space size decreases in the direction opposite to the rotation direction of the first connector, and the second connector to rotate, thereby realizing the normal rotation function of the rotating shaft. At the same time, the wide end of the second accommodating cavity, whose space size decreases in the same direction as the rotation direction of the first connector, moves toward the motorized components in the second accommodating cavity, thereby preventing the motorized components from getting stuck in the narrow end of the second accommodating cavity and thus preventing the normal rotation of the rotating shaft from being affected. The rotating shaft provided in the embodiment of the present application, while having the normal rotation function, also has a locking function, which can prevent the object fixedly connected to the second connector from shaking.

[0056] In one embodiment, Figure 12 As shown, the first end of the second connecting member 20 includes at least one through hole 22 , which communicates with a pair of second recessed portions 21 ; the rotating shaft also includes at least one spring 60 , which is disposed in the through hole 22 .

[0057] In the embodiment of this application, Figure 13 As shown, a through hole 22 is opened between a pair of second recessed portions 21 of the second connecting member 20, and a spring 60 is placed in the through hole 22 so that the motorized component 30 can be squeezed by the spring at the narrow end 51 of the respective accommodating cavity 50, so that when the second connecting member 20 rotates, the motorized component in a critical state of being stuck can be instantly stuck at the narrow end 51 of the corresponding accommodating cavity 50, thereby instantly blocking the second connecting portion 20 and the positioning component 40, thereby locking the rotating shaft and preventing the second connecting member 20 from continuing to rotate.

[0058] In the embodiment of the present application, the first end of the second connecting member includes at least one through hole connected to a pair of second recessed portions, and a spring is placed in the through hole. The spring can squeeze the motorized component at the narrow end of the respective accommodating cavity by the spring, so that when the second connecting member rotates, the motorized component in the critical state of jamming can be instantly jammed at the narrow end of the corresponding accommodating cavity, thereby instantly jamming the second connecting portion and the positioning component, realizing instantaneous locking of the rotating shaft, effectively reducing the locking time of the rotating shaft, and improving the locking efficiency of the rotating shaft.

[0059] In one embodiment, the two protrusions 11 and the two first recesses 12 have the same length along the rotation direction of the first connecting member 10 .

[0060] In the embodiment of the present application, when the first connector 10 includes two protrusions 11 and two first recesses 12, the lengths of the two protrusions 11 and the two first recesses 12 along the circumference of the first connector 10 can be the same, that is, one-quarter of the circumference. Therefore, when the first connector 10 rotates, the two protrusions 12 can drive the motorized component 30 in the accommodating cavity to simultaneously contact the second connector 20, thereby driving the second connector 20 to rotate.

[0061] For example, as above Figure 10 As shown, when the first connecting member 10 rotates, the two protrusions 12 can drive the motorized components in the accommodating chamber 501 and the accommodating chamber 503 to contact the second connecting member 20 at the same time, and simultaneously drive the second connecting member 20 to rotate.

[0062] As above Figure 11 As shown, when the first connecting member 10 rotates, the two protrusions 12 can drive the motorized components 30 in the accommodating cavities 502 and 504 to contact the second connecting member 20 at the same time, and simultaneously drive the second connecting member 20 to rotate.

[0063] In an embodiment of the present application, the two protrusions and the two first recessed portions of the first connecting member have the same length along the rotation direction of the first connecting member, so that when the first connecting member rotates, the two protrusions can drive the motorized components in the accommodating cavity to contact the second connecting member at the same time, and at the same time drive the second connecting member to rotate, so that the two symmetrical positions of the second connecting member are subjected to the same force, and under the same force, the rotation of the second connecting member is more stable.

[0064] In one embodiment, Figure 14 As shown, the concave surface of the second concave portion 21 matches the motorized component 30. The concave surface of the second concave portion 21 includes a driving surface 211 and a locking surface 212, and the distance between the locking surface 212 and the inner surface of the positioning component 40 gradually decreases.

[0065] In the embodiment of the present application, the concave surface of the second concave portion 21 matches the motor component 30, and the shape of the concave surface can match the motor component 30, for example Figure 14 The middle concave surface can be an arc surface, matching the surface shape of the motor component 30; or the size of the space formed by the concave surface can match the motor component 30, that is, the space formed by the concave surface should be able to accommodate the motor component 30.

[0066] In this embodiment of the present application, the recessed surface may include a driving surface 211 and a locking surface 212. The driving surface 211 may be a flat surface or an arcuate surface; the distance between the locking surface 212 and the inner surface of the positioning member 40 gradually decreases, and gradually decreases in the direction away from the driving surface 211, thereby forming a spatial shape of the accommodating cavity 50 that is wide at one end and narrow at the other end, that is, forming a narrow end 51 and a wide end 52 of the accommodating cavity 50.

[0067] Thus, the rotating shaft can achieve the locking function by clamping the motor component 30 through the narrow end, and can sequentially drive the motor component 30 and the second connecting member 20 to rotate through the wide end, thereby achieving the normal rotation function. That is, the rotating shaft can achieve the locking function by the locking surface, and can sequentially drive the motor component 30 and the second connecting member 20 to rotate through the driving surface, thereby achieving the normal rotation function.

[0068] The concave surface of the second recessed portion in the rotating shaft provided in the embodiment of the present application matches the motorized component, thereby allowing the space formed by the recessed surface to successfully accommodate the motorized component. The concave surface of the second recessed portion in the embodiment of the present application includes a driving surface and a locking surface. The distance between the locking surface and the inner surface of the positioning component gradually decreases, thereby forming a narrow end and a wide end of the accommodating cavity, allowing the rotating shaft to achieve both locking and normal rotation functions.

[0069] In one embodiment, Figure 15 As shown, a rotatable display is provided, which includes a driver 2, a display 3 and the rotating shaft 1 described in the above embodiment, the second end of the first connecting member 10 of the rotating shaft 1 is connected to the driver 2, and the second end of the second connecting member 20 of the rotating shaft 1 is connected to the display 3.

[0070] In the embodiment of the present application, the rotating shaft 1 includes a first connecting member 10, a second connecting member 20, a motorized component 30 and a positioning component 40, which form at least one pair of accommodating cavities 50, and the motorized component 30 is accommodated in the accommodating cavity 50. The size of the accommodating cavity 50 decreases along the rotation direction of the first connecting member 10 or the second connecting member 20; the size of the pair of accommodating cavities 50 decreases in opposite directions.

[0071] When the driver 2 rotates the first connecting member 10 of the rotating shaft 1, the first connecting member 10 drives the second connecting member 20 to rotate, thereby driving the display 3 to rotate. When the display 3 is shaken by external influences, the second connecting member 20 is driven to rotate, and the rotating shaft 1 is locked, preventing the second connecting member 20 from further rotating, thereby preventing the display 3 from shaking.

[0072] In one possible implementation, Figure 16 As shown, the rotatable display may further include a base 4, the driver 2 and the rotating shaft 1 may be disposed within the base 4, and the display 3 may be disposed in a through-hole formed in the base 4, the shape of the through-hole matching the shape of the display 3. In this case, the rotating shaft 1 may only include a first connecting member 10, a second connecting member 20, and a motorized component 30, and the first connecting member 10, the second connecting member 20, the motorized component 30, and the base 4 may form a receiving cavity 50.

[0073] The rotatable display provided in an embodiment of the present application includes a driver, a display, and a rotating shaft. The second end of the first connecting member of the rotating shaft is connected to the driver, and the second end of the second connecting member of the rotating shaft is connected to the display. The rotatable display can be driven by the driver to achieve normal rotation of the display, and the rotating shaft can be locked to prevent the display from shaking when the display shakes.
