The nut assembly 10 includes a nut 11, an actuator 12 and a housing 13. The housing 13 has a receiving space 1312, and the nut 11 and the actuator 12 are sequentially disposed in the receiving space 1312 along a longitudinal direction of the housing 13. As shown in fig. 1, the longitudinal direction of the housing 13 is, for example, the y-axis direction of the coordinate axes.

The outer wall of the nut 11 is provided with a first interlocking portion 111. In some embodiments, as shown in fig. 1 and 2, the first linkage portion 111 may be a groove extending in a length direction. In this embodiment, the groove may extend through the outer wall of the nut 11 in the length direction, i.e. the length of the groove is greater than or equal to the length of the outer wall. In other embodiments, the groove may not extend through the outer wall of the nut 11, i.e. the length of the groove is less than the length of the outer wall. Alternatively, the number of the first linkage portions 111 may be set according to actual needs, for example, the number of the first linkage portions 111 may be 1, 2, 4, 8, and the like. In other embodiments, the first linkage portion 111 may also be a protrusion extending in a length direction.

It will be appreciated that the inner wall of the nut 11 is provided with an internal thread 112 which co-operates with the external thread of the bolt 20, so that the nut 11 and bolt 20 co-operate to effect fastening. In this embodiment, the shape and size of the internal thread 112 of the nut 11 are not limited, and may be set according to actual needs. The hardness of the material of the nut 11 is greater than the predetermined hardness so that the first interlocking part 111 of the nut 11 engages with the second interlocking part 121 of the actuator 12, and the nut 11 is sufficiently hard to rotate the actuator 12. Optionally, the preset hardness is, for example, 40HRC, 55HRC or 90 HRC. The nut 11 is made of, for example, carbon steel, stainless steel, copper, alloy, or the like.

As shown in fig. 1 and 3, the actuator 12 includes at least one second linkage 121. The second linkage portion 121 may include a first connection portion 1211 and a second connection portion 1212 extended from the first connection portion 1211. The first connecting portion 1211 can be engaged with the first linking portion 111 and can move along the length direction. In this embodiment, the first connecting portion 1211 is a bar-shaped arm having a width less than or equal to the width of the groove, so that the bar-shaped arm can be clamped in the groove and can move along the length direction. In another embodiment, the first connection portion 1211 may be a groove for engaging with the first interlocking portion 111 when the first interlocking portion 111 is a protrusion. In this embodiment, the second connecting portion 1212 may be a first protrusion provided on the first connecting portion 1211, and is configured to move to the first position along the length direction following the first connecting portion 1211, so as to engage with the third coupling portion 1311 on the housing 13. In other embodiments, the second connecting portion 1212 may also be a groove. Alternatively, the actuating member 12 may be embodied as a pawl structure.

In the present embodiment, a second link 121 may be engaged with a first link 111 and/or a third link 1311. At this time, the number of the second links 121 is less than or equal to the number of the first links 111, and/or less than or equal to the number of the third links 1311. For example, if there are 4 first linkage parts 111 and 8 third linkage parts 1311, then there may be 1, 2, 3 or 4 second linkage parts 121, but it cannot be larger than the number (4) of first linkage parts 111. When the first linking portion 111 is a groove, the second connecting portion 1212 is a first protrusion, and the third linking portion 1311 is a second protrusion, at least one of the groove, the first protrusion, and the second protrusion may be annularly spaced, and the number of the first protrusions may be less than or equal to the number of the groove and the number of the second protrusions.

Referring to fig. 5, fig. 5 is a cross-sectional view of the nut assembly provided herein at position X-X'. As shown in fig. 1 to 5, in the present embodiment, the number of the first linkage portions 111 is 4, the number of the third linkage portions 1311 is 8, the number of the second linkage portions 121 is 4, and the 4 second linkage portions 121 are uniformly arranged and symmetrically distributed with respect to the first linkage portions 111 and the third linkage portions 1311. Alternatively, in other embodiments, the plurality of second linkages 121 may also be arranged non-uniformly, for example, the plurality of second linkages 121 are arranged adjacently, i.e., separated by only one third linkage 1311 in the middle.

In other embodiments, the plurality of second links 121 may be engaged with the plurality of first links 111 and/or the plurality of third links 1311. At this time, the number of second links 121 may be greater than the number of first links 111, or may be greater than the number of third links 1311. For example, when the first linkage 111 is a concave groove and the second linkage 121 is a convex groove, in this case, only one second linkage 121 may be accommodated in one first linkage 111, or a plurality of second linkages 121 may be accommodated, and for example, when the second linkage 121 and the third linkage 1311 are convex grooves, one second linkage 121 may be accommodated between two third linkages 1311, or a plurality of second linkages 121 may be accommodated. When the first link portion 111 is a groove, the second connecting portion 1212 is a first protrusion, and the third link portion 1311 is a second protrusion, the number of the first protrusions may be greater than the number of the grooves and the number of the second protrusions.

Optionally, at least one of the end surfaces a of the first protrusion facing away from the nut 11 is not perpendicular to the length direction. As shown in fig. 3, at least one of the end surfaces a of the first protrusion far from the nut 11 is not perpendicular to the length direction (y-axis direction), that is, at least one of the end surfaces a of the first protrusion far from the nut 11 is an inclined surface, so that when the first protrusion moves to a gap between two second protrusions in the length direction, the contact area with the second protrusion can be reduced, and the first protrusion can be prevented from being caught by the two second protrusions. In some embodiments, the end surface a of the first protrusion, which is far away from the nut 11, is not perpendicular to the length direction, so as to reduce the contact area with the second protrusion to a greater extent, thereby avoiding being caught by the two second protrusions. As shown in fig. 3, for example, neither end surface a of the first projection facing away from the nut 11 is perpendicular to the longitudinal direction.

In some embodiments, the nut assembly 10 further includes a magnet member 14, the magnet member 14 being located at an end of the actuator 12 remote from the nut 11, the magnet member 14 moving the actuator 12 between the first position and the second position when subjected to an external magnetic force.

In some embodiments, the actuator 12 may further include an abutting portion 122, and the abutting portion 122 is disposed between the nut 11 and the magnet member 14 for moving the second coupling portion 121 in the length direction. The second coupling portion 121 extends from an edge of the abutting portion 122 and is provided between the housing 13 and the nut 11.

Alternatively, the actuator 12 may or may not be hollow. It is understood that when the length of the screw 21 of the bolt 20 is short or the length of the second coupling portion 121 is long, the abutting portion 122 may not abut against the screw 21, so that the abutting portion 122 may not be provided with a hollow structure, but the length of the screw 21 can still cooperate with the nut 11 to achieve fastening. It will be appreciated that the length of the screw 21 may be less than, equal to, or greater than the length of the nut 11.

In some embodiments, the inner wall edge of the abutting portion 122 is provided with a bearing platform 1221, the bearing platform 1221 is used for abutting against the elastic member 142, and the shake of the elastic member 142 can be reduced. It is understood that when the abutting portion 122 has a hollow structure and the diameter of the hollow portion is larger than that of the elastic member 142, the abutment between the abutting portion 122 and the elastic member 142 may be achieved by a bearing platform 1221 on the inner wall edge of the abutting portion 122. As shown in fig. 3, the abutting portion 122 is provided with an annular shelf 1221 near the inner wall edge of the second linkage portion 121. The width of the platform 1221 is not limited, and the width of the platform 1221 is, for example, 0.1 to 0.5 cm. Alternatively, the abutment 1221 may be formed integrally with the abutting portion 122, or the abutment 1221 may be formed on the inner wall edge of the abutting portion 122 after the abutting portion 122 is formed.

As shown in fig. 1, the magnet part 14 includes a passive magnet 141 and an elastic member 142 sequentially arranged in a length direction of the housing 13. The passive magnet 141 is connected to the actuator 12, and the elastic member 142 is located on a side of the passive magnet 141 away from the nut 11, and is used for enabling the passive magnet 141 to be located at a set position in the length direction, i.e. a second position, when the passive magnet 141 is not subjected to an external magnetic force. The elastic member 142 may be any member having elastic deformation, i.e., a member that is deformed when an external force is applied thereto and is restored to its original shape and size if the external force is removed. The elastic member 142 is, for example, a spring. The passive magnet 141 is connected to the actuator 12 to move the actuator 12 in the longitudinal direction. Optionally, the passive magnet 141 and the actuator 12 are connected by welding or glue.

It should be noted that the passive magnet 141 in the present embodiment is only for distinguishing from the active magnet 52 in the subsequent embodiments, and the passive magnet 141 and the active magnet 52 may be any magnets that attract each other and have a magnetic force sufficient to drive the actuating member 12, and the naming is not limited thereto.

In the present embodiment, the passive magnet 141 is a hollow structure, and the elastic member 142 penetrates the passive magnet 141, and has one end abutting on the bearing platform 1221 of the abutting portion 122 and the other end abutting on the first end portion of the housing 13. Specifically, the passive magnet 141 is an annular magnet. In some embodiments, the platform 1221 may also be disposed on an edge of the inner wall of the passive magnet 141, and the elastic member 142 abuts the platform 1221 of the passive magnet 141. In other embodiments, the passive magnet 141 may not have a hollow structure, and one end of the elastic member 142 directly abuts on one end near the passive magnet 141, and the other end abuts on the first end of the housing 13.

In some embodiments, the abutting portion 122 may be a passive magnet 141, i.e., the abutting portion 122 is directly made of a magnetic material. In other embodiments, the actuator 12 (including the abutting portion 122 and the second linkage portion 121) can be a passive magnet 141, i.e., the actuator 12 is directly made of a magnetic material. At this time, one end of the elastic member 142 may abut against the abutting portion 122 or the abutment 1221 on the abutting portion 122. Optionally, the elastic member 142 is made of a magnetically conductive material, so that the elastic member 142 can reduce the shaking of the elastic member 142 under the action of magnetic force, and is better fixed on the platform 1221.

Alternatively, the magnetic force generated by the close proximity of the passive magnet 141 and the active magnet 52 is large enough to drive the actuator 12 to move along the length direction by the magnetic force generated between the passive magnet 141 and the active magnet 52 when the active magnet 52 is close.

As shown in fig. 1 and 4, the inner wall of the housing 13 is provided with a third coupling portion 1311. In the present embodiment, the housing 13 includes a housing main body 131 and a cover plate 132. The housing main body 131 is provided with an accommodating space 1312, the cover plate 132 is provided at a first end of the housing main body 131 as a first end portion of the housing 13, and the nut 11, the actuator 12 and the magnet member 14 are sequentially provided in a direction close to the first end portion. Optionally, the housing main body 131 and the cover plate 132 are connected by welding or glue to achieve the fixed connection of the housing main body 131 and the cover plate 132. It is understood that the housing main body 131 and the cover plate 132 may be fixedly connected in other manners, and the embodiment is not limited thereto. A second side of the housing body 131 opposite to the first end extends in a radial direction to form a hollow bottom plate 1313, and the bottom plate 1313 is not in contact with the nut 11. In this embodiment, the nut 11 is not directly contacted with the housing 13, but contacted with the second linkage 121 through the first linkage 111, and the second linkage 121 is contacted with the third linkage 1311 on the housing 13 to realize indirect contact with the housing 13, so that when the housing 13 rotates, the nut 11 in the housing 13 can also rotate along with the rotation of the housing 13, and the fastening can be released.

With continued reference to fig. 4, specifically, the inner wall of the housing main body 131 is provided with a third linkage 1311. When the actuator 12 moves to the first position, the third link 1311 is used to limit the rotation direction (e.g., X-axis direction) of the second connecting portion 1212. Specifically, the third link 1311 may be a plurality of second protrusions on the inner wall of the housing 13, and when the actuator 12 moves to the first position, the second connecting portion 1212 is located between two adjacent second protrusions, so that the two second protrusions limit the second connecting portion 1212 in the rotation direction. In other embodiments, the third link 1311 may also be a second protrusion on the inner wall of the housing 13, and when the actuator 12 moves to the first position, the second connecting portion 1212 is located at one side of the second protrusion, so that the second protrusion abuts against the second link 121 and pushes the second link 121 to rotate along the width direction (X-axis direction) of the housing 13. Alternatively, when the second connecting portion 1212 of the second coupling portion 121 is a protrusion, the third coupling portion 1311 may be a plurality of grooves of an inner wall of the housing 13, and the grooves and the protrusion may achieve a snap-fit.

As shown in fig. 1 and 4, alternatively, at least one of the end surfaces of the second projection far from the magnet part 14 is not perpendicular to the longitudinal direction, that is, at least one of the end surfaces B of the second projection far from the magnet part 14 is an inclined surface, so that when the first projection moves to a gap between two second projections in the longitudinal direction, a contact area with the first projection can be reduced, and thus the first projection can be prevented from being caught. In some embodiments, the end surface of the second protrusion away from the magnet part 14 is not perpendicular to the length direction to reduce the contact area with the first protrusion to a greater extent, so that the first protrusion can be prevented from being caught.

In some embodiments, the nut assembly 10 may further include a spacer 15, and the spacer 15 is disposed at a hollow position of the bottom plate 1313 and is in contact with the nut 11. Wherein the diameter of the hollow position of the bottom plate 1313 is smaller than the maximum diameter of the actuating member 12 to prevent the housing 13 from being detached from the nut 11. The spacer 15 serves to separate the bottom surface of the nut 11 from the bottom plate 1313 of the housing 13 to prevent the nut 11 from being rotated by a frictional force generated by the direct contact between the bottom surface of the nut 11 and the bottom plate 1313 of the housing 13 when the interlocking structure is released and the housing 13 is rotated with respect to the bolt 20. Alternatively, the spacer 15 is, for example, a gasket, and the material of the gasket may be rubber, silicon gel, or the like.

Referring to fig. 6 to 7, fig. 6 is a schematic longitudinal sectional view of an E-E' of a nut assembly linkage structure provided in the present application, and fig. 7 is an enlarged schematic view of a region H in fig. 6 in the present application.

Further, as shown in fig. 7, the height of the spacer 15 is greater than the height of the bottom plate 1313, so that the bottom surface of the nut 11 can be spaced apart from the bottom plate 1313 of the housing 13.

Referring to fig. 8, fig. 8 is a schematic longitudinal sectional view of a nut assembly decoupling structure according to the present application.

As shown in fig. 6 and 8, the magnet member 14, under the action of the external magnetic force, drives the actuator 12 to move to the first position in the length direction, so that the first linkage portion 111, the second linkage portion 121 and the third linkage portion 1311 form a linkage structure, and the linkage structure enables the nut 11 to rotate along with the housing 13; the magnet member 14, when not subjected to external magnetic force, moves the actuator 12 to the second position in the longitudinal direction, so that the first, second and

third linkage portions

111, 121 and 1311 are released from the linkage structure.

Specifically, as shown in fig. 6, the passive magnet 141 in the magnet member 14 is under the action of the active magnet 52, and drives the actuator 12 to move to the first position, i.e. the unlocking position, in which the first connecting portion 1211 of the second linkage portion 121 is engaged with the first linkage portion 111, and the second connecting portion 1212 of the second linkage portion 121 is engaged with the third linkage portion 1311, so that the first linkage portion 111, the second linkage portion 121, and the third linkage portion 1311 form a linkage structure, and the linkage structure enables the nut 11 to rotate along with the housing 13. Specifically, when the linkage structure is formed, the bar-shaped arm of the actuator 12 on one side is clamped in the groove of the nut 11, and the first protrusion of the actuator 12 on the other side is clamped between the two second protrusions of the housing main body 131, so that the groove, the bar-shaped arm, the first protrusion and the second protrusion form the linkage structure, and the linkage structure can enable the nut 11 to rotate along with the housing 13. It can be understood that the nut assembly in the unlocked state can be disassembled by a wrench or other common disassembling tools, which is very convenient.

Specifically, as shown in fig. 8, the passive magnet 141 in the magnet member 14, without being acted by the active magnet 52, drives the actuator 12 to move to the second position, i.e., the locking position, in which the first connection portion 1211 of the second linkage portion 121 is engaged with the first linkage portion 111, but the second connection portion 1212 of the second linkage portion 121 is misaligned with the third linkage portion 1311, so that the first linkage portion 111, the second linkage portion 121, and the third linkage portion 1311 are released from the linkage structure, and at this time, the nut 11 cannot rotate with the housing 13. Specifically, when the linkage structure is released, the bar-shaped arm of the actuator 12 on one side is still clamped in the groove of the nut 11, but the first protrusion of the actuator 12 on the other side is close to the bottom surface of the housing 13 and is staggered with the second protrusion, so that the groove, the bar-shaped arm, the first protrusion and the second protrusion release the linkage structure.
