Description

Technical Field

[0001] The present application relates to the field of assembly technology, and in particular to a nut structure, a locking device, a battery device and an electrical device. Background Art

[0002] The nut structure is a fastening component that cooperates with the bolt structure to lock at least two parts. The nut structure has a wide range of applications and can be used to assemble parts in different fields. However, the versatility of the same nut structure is currently poor, and it is difficult to meet the assembly requirements of different application scenarios. Utility Model Content

[0003] In view of the above problems, the present application provides a nut structure, a locking device, a battery device and an electrical device, which can improve the versatility of the nut structure.

[0004] In the first aspect, an embodiment of the present application provides a nut structure, including a nut body and a support assembly, the nut body is provided with a threaded hole, the nut body includes a first end and a second end arranged opposite to each other along the axial direction of the threaded hole, the first end is used to face the workpiece to be locked; the support assembly is arranged on the outer peripheral side of the nut body, the support assembly includes an elastic member for deforming along the axial direction, and one side of the support assembly along the axial direction is protruding relative to the first end of the nut body to suspend the nut body.

[0005] In the above scheme, the nut body is provided with a threaded hole, which can cooperate with the bolt structure to lock at least two workpieces to be locked. The nut body includes a first end and a second end arranged opposite to each other along the axial direction of the threaded hole, and the first end faces the workpiece to be locked. In addition, a support assembly is provided on the outer peripheral side of the nut body, and the support assembly is protruded relative to the first end protruding from the nut body along one side of the axial direction to suspend the nut body, so that an activity space is formed between the nut body and the surface of the workpiece to be locked. On this basis, the support assembly is provided to include an elastic member, so that an axial force is applied to the nut structure through the bolt structure, and the axial force can be transmitted from the nut structure to the elastic member, so that the elastic member is deformed along the axial direction. In this process, the nut body can move axially within the range corresponding to the aforementioned activity space, thereby realizing the height adjustment of the nut structure, so that it can meet the height requirements of the nut structure in various application scenarios, and improve the versatility of the nut structure.

[0006] In some embodiments, the elastic member is arranged to be inclined relative to the axial direction.

[0007] In the above solution, by setting the axial inclination of the elastic member relative to the threaded hole, the difficulty of the elastic member deforming along the axial direction after being subjected to the axial force can be reduced, thereby reducing the difficulty of adjusting the height of the nut structure.

[0008] In some embodiments, the support assembly further includes a protective member, which is disposed on a side of the elastic member close to the first end, and a side of the protective member axially away from the elastic member is protruding relative to the first end of the nut body.

[0009] In the above scheme, a protective member is arranged on the side of the elastic member close to the first end, so that the side of the protective member axially away from the detection member is protruding relative to the first end of the nut body. On the one hand, the nut body can be suspended so that a movable space can be formed between the nut body and the surface of the workpiece to be locked for the nut body to move axially. On the other hand, when the elastic member is subjected to axial force, the protective member can play a protective role between the elastic member and the workpiece to be locked, reducing the risk of the elastic member directly contacting the surface of the workpiece to be locked and scratching the surface of the workpiece to be locked.

[0010] In some embodiments, the nut body is connected to the protective member and is movably disposed relative to the protective member along the axial direction of the threaded hole.

[0011] In the above solution, the nut body is connected to the protective member, which can improve the stability of the protective member and reduce the risk of the protective member moving during use. In addition, the nut body is movably arranged relative to the protective member along the axial direction. When the elastic member is deformed along the axial direction due to the axial force, the nut body can move along the axial direction within the range corresponding to the activity space to achieve height adjustment of the nut structure.

[0012] In some embodiments, a first protrusion is provided on the outer peripheral side of the nut body, and the first protrusion is arranged close to the first end. The protective member includes a main body and a second protrusion arranged on a side of the main body close to the nut body, and at least a portion of the second protrusion abuts against the first protrusion from the side of the first protrusion axially close to the second end.

[0013] In the above scheme, a first protrusion is arranged on the outer peripheral side of the nut body, the first protrusion is arranged close to the first end, and a second protrusion is arranged on the side of the main body of the protective member close to the nut body, at least part of the second protrusion abuts against the first protrusion from the side of the first protrusion axially close to the second end. On the one hand, the first protrusion can work together with the elastic member to limit the protective member, improve the stability of the protective member, and enable the nut body 10 to move axially relative to the protective member in the direction from the second end to the first end. On the other hand, it can also reduce the difficulty of connecting the nut body and the protective member, and improve the assembly efficiency of the nut structure.

[0014] In some embodiments, in a direction from the second end to the first end, a width of the second protrusion along the radial direction of the threaded hole tends to decrease.

[0015] In the above scheme, the width of the second protrusion is set to decrease in the direction from the second end to the first end, which can reduce the risk of position interference between the nut body and the second protrusion when the nut body moves axially within the range corresponding to the active space, thereby improving the reliability of the nut structure.

[0016] In some embodiments, in a direction from the second end to the first end, the elastic member is inclined toward a side away from the nut body.

[0017] In the above scheme, the elastic member is inclined toward the side away from the nut body in the direction from the second end to the first end, which can increase the distance from the contact point between the elastic member and the protective member to the second protrusion, reduce the influence of the axial force exerted on the elastic member on the second protrusion, and improve the connection reliability between the second protrusion and the first protrusion of the nut body.

[0018] In some embodiments, in the axial direction, a height of the elastic member is greater than a height of a portion of the protective member protruding relative to the first end.

[0019] In the above scheme, by setting the axial height of the elastic part to be greater than the axial height of the protruding part of the protective part relative to the first end, during the axial deformation of the elastic part, the nut body can fully utilize the range corresponding to the active space to move, thereby increasing the height adjustment range of the nut structure.

[0020] In some embodiments, the support assembly is disposed around the circumference of the nut body.

[0021] In the above solution, the support assembly is arranged around the circumference of the nut body, which can improve the structural strength of the support assembly and improve its support reliability for the nut body.

[0022] In some embodiments, the nut body includes a flange portion and a rod portion arranged on one side of the flange portion, wherein the first end is located at an end of the rod portion away from the flange portion, and the threaded holes penetrate the flange portion and the rod portion respectively; the support assembly is arranged on the outer peripheral side of the rod portion, and the support assembly contacts the flange portion along the side axially away from the first end.

[0023] In the above scheme, by arranging the support assembly on the outer peripheral side of the rod portion, the side of the support assembly axially away from the first end is in contact with the flange portion. Therefore, when an axial force is applied to the nut body through the bolt structure, the flange portion can axially squeeze the support assembly and directly transmit the axial force to the support assembly in the axial direction, so that the elastic part of the support assembly is deformed in the axial direction. On the one hand, it can reduce the risk of the axial force being decomposed in other directions during the transmission process and reduce the difficulty of the elastic part being deformed in the axial direction. On the other hand, it can improve the connection reliability between the support assembly and the nut body and reduce the risk of cracks or even separation at the connection part between the support assembly and the nut body during the deformation of the elastic part.

[0024] In some embodiments, the support assembly further includes a connecting member connected to the elastic member, the connecting member extending radially along the threaded hole and being located between the elastic member and the flange portion, and the connecting member contacts the flange portion.

[0025] In the above scheme, by arranging a connecting piece between the elastic piece and the flange part, the connecting piece extends radially along the threaded hole and contacts the flange part, thereby increasing the contact area between the flange part and the support assembly and reducing the risk of damage to the flange part and the support assembly during the process of transmitting axial force.

[0026] In a second aspect, an embodiment of the present application provides a locking device, comprising a bolt structure and a nut structure as described in any one of the above items, wherein the bolt structure is threadedly connected to a nut body of the nut structure.

[0027] In a third aspect, an embodiment of the present application provides a battery device, comprising the above-mentioned locking device.

[0028] In a fourth aspect, an embodiment of the present application provides an electrical device, comprising the above-mentioned battery device.

[0054] The nut structure is a fastening component that cooperates with the bolt structure and is used to lock at least two parts. The nut structure has a wide range of applications and can be used to assemble parts in different fields. However, the height requirements for the nut structure are different in different application scenarios. For example, when the nut structure is used on a PCB (Printed Circuit Board), the height of the nut structure is required to be greater than the protruding height of some electrical components on the PCB. The nut structure can protect the electrical components and reduce the risk of the electrical components being damaged by interference from other structures during the use of the PCB.

[0055] However, since the height dimension of the current nut structure is usually a fixed value, one nut structure cannot simultaneously meet the height requirements of multiple application scenarios, resulting in poor versatility of the nut structure.

[0056] In order to solve the above problems, the embodiment of the present application provides a nut structure, including a nut body and a support assembly, wherein the nut body is provided with a threaded hole, and the nut body includes a first end and a second end arranged opposite to each other along the axial direction of the threaded hole, and the first end is used to face the workpiece to be locked; the support assembly is arranged on the outer peripheral side of the nut body, and the support assembly includes an elastic member for deforming along the axial direction, and one side of the support assembly along the axial direction is convex relative to the first end of the nut body to suspend the nut body. Among them, the nut body can cooperate with the bolt structure to lock at least two workpieces to be locked. In addition, the nut body includes a first end and a second end relatively arranged along the axial direction of the threaded hole, the first end facing the workpiece to be locked, and a support assembly is arranged on the outer peripheral side of the nut body, and the support assembly is protruded relative to the first end protruding from the nut body on one side along the axial direction to suspend the nut body, so that a movable space is formed between the nut body and the surface of the workpiece to be locked. On this basis, the support assembly is arranged to include an elastic member, so that an axial force is applied to the nut structure through the bolt structure, and the axial force can be transmitted from the nut structure to the elastic member, so that the elastic member is deformed along the axial direction. During this process, the nut body can move axially within the range corresponding to the aforementioned movable space, thereby realizing the height adjustment of the nut structure, so that it can meet the height requirements of the nut structure in various application scenarios, and improve the versatility of the nut structure.

[0057] It should be noted that the nut structure provided in the embodiment of the present application can be used in a variety of scenarios, especially in the battery field, to assemble the PCB circuit board and other components of the aforementioned battery device.

[0062] Please refer to Figure 2 , Figure 2 An exploded view of a battery device 100 provided in some embodiments of the present application. The battery device 100 includes a battery case and a battery cell 110. In some embodiments, the battery case may include a first case 120 and a second case 130, the first case 120 and the second case 130 cover each other, and the first case 120 and the second case 130 jointly define a receiving cavity for accommodating the battery cell 110.

[0066] In some embodiments, a battery cell assembly is generally formed by arranging a plurality of battery cells 110 .

[0067] As an example, the battery cell assembly may be a battery module, which is formed by arranging and fixing a plurality of battery cells 110 to form an independent module. As an example, the battery module may be formed by bundling a plurality of battery cells 110 by a cable tie.

[0074] In some embodiments, the battery device 100 may be an energy storage device, which includes an energy storage container, an energy storage cabinet, and the like.

[0075] Next, the embodiment of the present application will describe the structure of the nut structure in detail with reference to the accompanying drawings.

[0076] See also Figures 3 to 5 In the first aspect, an embodiment of the present application provides a nut structure, including a nut body 10 and a support assembly 20. The nut body 10 is provided with a threaded hole 11. The nut body 10 includes a first end S1 and a second end S2 which are arranged opposite to each other along the axial direction of the threaded hole 11. The first end S1 is used to face a workpiece 30 to be locked; the support assembly 20 is arranged on the outer peripheral side of the nut body 10. The support assembly 20 includes an elastic member 21 for deforming along the axial direction, and one side of the support assembly 20 along the axial direction is protruding relative to the first end S1 of the nut body 10 to suspend the nut body 10.

[0077] The nut structure is used in conjunction with the bolt structure 40 to lock the fastening components of at least two workpieces 30 to be locked. During the locking process, the bolt structure 40 can pass through the at least two workpieces 30 to be locked and be threadedly connected with the nut structure. At this time, the at least two workpieces 30 to be locked are locked between the nut structure and the head of the bolt structure 40. The nut structure includes a nut body 10 and a support assembly 20. The nut body 10 is a component of the nut structure used to be threadedly connected with the bolt structure 40 to lock at least two workpieces 30 to be locked. The nut body 10 is provided with a threaded hole 11. The inner wall of the threaded hole 11 is provided with an internal thread, which can be engaged with the external thread on the bolt structure 40 to achieve a threaded connection between the nut structure and the bolt structure 40. The nut body 10 includes a first end S1 and a second end S2 which are arranged opposite to each other in the axial direction of the threaded hole 11. When the nut structure cooperates with the bolt structure 40 to lock at least two workpieces 30 to be locked, the first end S1 is an end of the nut body 10 axially facing the workpiece 30 to be locked, and the second end S1 is an end of the nut body 10 axially facing away from the workpiece 30 to be locked. It should be noted that the first end S1 and the second end S2 can be two end faces of the nut body 10 in the axial direction, or points within the two end faces of the nut body 10 in the axial direction.

[0078] The support assembly 20 is a component used to support the nut body 10 so that the nut body 10 is suspended. The support assembly 20 is arranged on the outer peripheral side of the nut body 10. Specifically, on the outer peripheral side of the nut body 10, the support assembly 20 can be arranged around the circumference of the nut body 10, or the support assembly 20 can also be located on opposite sides of the nut body 10 along the radial direction of the threaded hole 11. When the support assembly 20 is arranged on the outer peripheral side of the nut body 10, it can be connected to the nut body 10. There are many ways to connect the support assembly 20 to the nut body 10. For example, the support assembly 20 can be connected to the nut body 10 by welding, or the support assembly 20 can also be an integrally formed structure with the nut body 10.

[0079] One side of the support component 20 along the axial direction is protruded relative to the first end S1 of the nut body 10. When the nut body 10 cooperates with the bolt structure 40 to lock at least two workpieces 30 to be locked, the side of the support component 20 protruding relative to the first end S1 of the nut body 10 contacts the surface of the workpiece 30 to be locked, so that the first end S1 of the nut body 10 and the surface of the workpiece 30 to be locked are spaced apart along the axial direction, and the nut body 10 is in a suspended state relative to the surface of the workpiece 30 to be locked, thereby realizing the suspension of the nut body 10. At this time, a gap can be formed between the first end S1 of the nut body 10 and the surface of the workpiece 30 to be locked. Figure 4 and Figure 5 The activity space K1 shown in the figure can be defined by the first end S1 of the nut body 10, the surface of the workpiece 30 to be locked, and the side surface of the support component 20 close to the nut body 10 along the radial direction of the threaded hole 11. The axial height of the activity space K1 is the axial height of the protruding part of the support component 20 relative to the first end S1 of the nut body 10.

[0080] It should be noted that the support component 20 is protruded relative to the first end S1 of the nut body 10 along one side of the axial direction. The elastic member 21 in the support component 20 may protrude relative to the first end S1 of the nut body 10 along one side of the axial direction, or other components in the support component 20 may protrude relative to the first end S1 of the nut body 10 along one side of the axial direction.

[0081] The support assembly 20 includes an elastic member 21, which is used to deform in the axial direction when subjected to an external force. It is understandable that the elastic member 21 can have a variety of structures and materials, for example, the elastic member 21 can be a metal sheet, or the elastic member 21 can also be a spring structure, or the elastic member 21 can also be a block structure made of elastic materials such as silicone. Specifically, when the nut body 10 cooperates with the bolt structure 40 to lock at least two workpieces 30 to be locked, an axial force can be applied to the nut body 10 through the bolt structure 40. The direction of the axial force is from the second end S2 to the first end S1, and it can be transmitted from the nut structure to the elastic member 21. When the axial force applied to the elastic member 21 is greater than its own elastic force, the elastic member 21 can be deformed in the axial direction under the action of the axial force. Since there is an active space K1 between the nut body 10 and the surface of the workpiece 30 to be locked, during the deformation process of the elastic member 21, the nut body 10 can be driven by the support assembly 20 to move in the direction from the second end S2 to the first end S1 within the range corresponding to the active space K1 to reduce the height of the nut structure in the axial direction.

[0082] It can be understood that the axial force applied by the bolt structure 40 to the nut body 10 can be the locking force of the bolt structure 40 on the nut body 10, which can be formed by the torque conversion between the bolt structure 40 and the nut body 10. The greater the torque between the bolt structure 40 and the nut body 10, the greater the axial force. Therefore, by adjusting the torque between the bolt structure 40 and the nut body 10, the magnitude of the axial force can be adjusted, that is, the deformation degree of the elastic member 21 and the axial movement distance of the nut body 10 can be adjusted, thereby realizing the height adjustment of the nut structure.

[0083] It should be noted that when the nut body 10 moves a certain distance in the direction from the second end S2 to the first end S1, the torque between the nut body 10 and the bolt structure 40 is adjusted to change the magnitude of the axial force acting on the elastic member 21, so that the axial force is smaller than the elastic force of the elastic member 21 itself, so that the elastic member 21 can restore the deformation in the direction from the first end S1 to the second end S2, so that the nut body 10 is reset in the direction from the first end S1 to the second end S2 under the drive of the support assembly 20, thereby increasing the axial height of the nut structure.

[0084] It should be noted that the axial force exerted on the elastic member 21 may also be a force applied to the elastic member 21 by an external structure, and is not limited to the locking force applied by the bolt structure 40 to the nut body 10 .

[0085] In the above scheme, the nut body 10 is provided with a threaded hole 11, which can cooperate with the bolt structure 40 to lock at least two workpieces 30 to be locked. The nut body 10 includes a first end S1 and a second end S2 arranged oppositely along the axial direction of the threaded hole 11, and the first end S1 faces the workpiece 30 to be locked. In addition, a support assembly 20 is provided on the outer peripheral side of the nut body 10, and the support assembly 20 is protruded relative to the first end S1 protruding from the nut body 10 on one side along the axial direction to suspend the nut body 10, so that an active space K1 is formed between the nut body 10 and the surface of the workpiece 30 to be locked. On this basis, the support assembly 20 is provided to include an elastic member 21, so that an axial force is applied to the nut structure through the bolt structure 40, and the axial force can be transmitted from the nut structure to the elastic member 21, so that the elastic member 21 is deformed along the axial direction. In this process, the nut body 10 can move axially within the range corresponding to the aforementioned active space K1, thereby realizing the height adjustment of the nut structure, so that it can meet the height requirements of the nut structure in various application scenarios, and improve the versatility of the nut structure.

[0086] Please continue reading Figures 3 to 5 In some embodiments, the elastic member 21 is tilted relative to the axial direction.

[0087] The inclination direction of the elastic member 21 can be various. For example, the elastic member 21 can be inclined toward the side away from the nut body 10 along the direction from the second end S2 to the first end S1. In this case, the minimum distance from the elastic member 21 to the nut body 10 along the radial direction of the threaded hole 11 can increase along the direction from the second end S2 to the first end S1. Alternatively, the elastic member 21 can be inclined toward the side close to the nut body 10 along the direction from the second end S2 to the first end S1. In this case, the minimum distance from the elastic member 21 to the nut body 10 along the axial direction of the threaded hole 11 can decrease along the direction from the second end S2 to the first end S1.

[0088] It should be noted that when the elastic member 21 is tilted relative to the axial direction, if the elastic member 21 is subjected to an axial force, according to the decomposition of the force, the axial force can be decomposed into a first component force and a second component force, wherein the direction of the first component force is parallel to the length direction of the elastic member 21, and the second component force is perpendicular to the length direction of the elastic member 21, and the second component force can make the elastic member 21 more easily deformed.

[0089] In the above solution, by setting the elastic member 21 to be axially inclined relative to the threaded hole 11, the difficulty of the elastic member 21 deforming along the axial direction after being subjected to the axial force can be reduced, thereby reducing the difficulty of adjusting the height of the nut structure.

[0090] Please continue reading Figures 3 to 5 In some embodiments, the support assembly 20 further includes a protective member 22, which is disposed on a side of the elastic member 21 close to the first end S1, and the protective member 22 is protruded relative to the first end S1 of the nut body 10 along a side axially away from the elastic member 21.

[0091] The protective member 22 can be a plate-like structure or a block-like structure, which is arranged on the side of the elastic member 21 close to the first end S1. When the nut body 10 and the bolt structure 40 cooperate to lock at least two workpieces 30 to be locked, the protective member 22 can be located between the workpiece 30 to be locked and the elastic member 21, and its surface axially away from the elastic member 21 contacts the surface of the workpiece 30 to be locked. Compared with setting the side of the elastic member 21 close to the first end S1 to directly contact the surface of the workpiece 30 to be locked, the contact area between the support assembly 20 and the workpiece 30 to be locked can be increased, and the pressure between the two can be reduced, thereby reducing the risk of scratching the surface of the workpiece 30 to be locked.

[0092] In the above scheme, a protective member 22 is arranged on the side of the elastic member 21 close to the first end S1, so that the protective member 22 is protruded relative to the first end S1 of the nut body 10 on the side axially away from the detection member. On the one hand, the nut body 10 can be suspended so that a movable space K1 can be formed between the nut body 10 and the surface of the workpiece 30 to be locked for the nut body 10 to move axially. On the other hand, when the elastic member 21 is subjected to axial force, the protective member 22 can play a protective role between the elastic member 21 and the workpiece 30 to be locked, thereby reducing the risk of the elastic member 21 directly contacting the surface of the workpiece 30 to be locked and scratching the surface of the workpiece 30 to be locked.

[0093] It should be noted that the protective member 22 is disposed on one side of the elastic member 21, and the projections of the two on the nut body 10 along the axial direction can overlap each other. In some optional embodiments, the projection of the elastic member 21 on the nut body 10 along the axial direction can be located within the projection of the protective member 22 on the nut body 10 along the axial direction, so as to improve the protective effect of the protective member 22.

[0094] In some embodiments, the nut body 10 is connected to the protective member 22 and is movably disposed along the axial direction of the threaded hole 11 relative to the protective member 22 .

[0095] The connection directions between the nut body 10 and the protective member 22 can be various. For example, the nut body 10 and the protective member 22 can be mutually clamped, or the protective member 22 can be arranged around the circumference of the nut body 10 and have an interference fit with the nut body 10 to achieve the connection between the protective member 22 and the nut body 10.

[0096] In the above solution, the stability of the protective member 22 can be improved, and the risk of the protective member 22 moving during use can be reduced. In addition, the nut body 10 is movably arranged relative to the protective member 22 along the axial direction. When the elastic member 21 is subjected to the axial force and deforms along the axial direction, the nut body 10 can move along the axial direction within the range corresponding to the activity space K1 to achieve height adjustment of the nut structure.

[0097] See also Figure 6 In some embodiments, a first protrusion 12 is provided on the outer peripheral side of the nut body 10, and the first protrusion 12 is arranged close to the first end S1. The protective member 22 includes a main body 221 and a second protrusion 222 arranged on a side of the main body 221 close to the nut body 10, and at least a portion of the second protrusion 222 abuts against the first protrusion 12 from the side of the first protrusion 12 axially close to the second end S2.

[0098] The first protrusion 12 is a component on the nut body 10 for abutting against the second protrusion 222 of the protective member 22. The first protrusion 12 is formed by the side protrusion of the nut body 10, and can be located at the first end S1 of the nut body 10, or have a small gap with the first end S1 of the nut body 10. The structure of the first protrusion 12 can be various. For example, the first protrusion 12 can be a plate-like structure extending along the radial direction of the threaded hole 11, or can also be other irregular structures.

[0099] The second protrusion 222 is a component on the protective member 22 for abutting against the first protrusion 12 of the nut body 10, and the second protrusion 222 is located on the side of the main body 221 of the protective member 22 close to the nut body 10 along the radial direction of the threaded hole 11. The structure of the second protrusion 222 can be various. Exemplarily, the second protrusion 222 can be a plate-like structure extending along the radial direction of the threaded hole 11. In this case, the thickness of the second protrusion 222 along the axial direction can be less than the thickness of the main body 221 along the axial direction, and the second protrusion 222 can be arranged close to the second end S2 along the axial direction. Alternatively, the second protrusion 222 can also be a conical structure, and the width of the conical structure can gradually decrease along the direction from the second end S2 to the first end S1. Of course, the second protrusion 222 can also be a structure of other regular or irregular shapes.

[0100] It can be understood that the protective member 22 is arranged on the side of the elastic member 21 close to the first end S1. At this time, the elastic member 21 can generate a force on the protective member 22 pointing to the first end S1 along the second end S2. On this basis, by arranging at least a part of the second protrusion 222 to abut against the first protrusion 12 from the side of the first protrusion 12 axially close to the second end S2, the first protrusion 12 can generate a force on the second protrusion 222 pointing to the second end S2 along the first end S1. The above two forces are equivalent to locking the protective member 22 axially, which can reduce the risk of movement of the protective member 22.

[0101] It should be noted that when at least part of the second protrusion 222 abuts against the first protrusion 12 from the side of the first protrusion 12 axially close to the second end S2, part of the second protrusion 222 can be located on the side of the first protrusion 12 axially close to the second end S2, or the second protrusion 222 can be integrally arranged on the side of the first protrusion 12 axially close to the second end S2.

[0102] It can be understood that during the assembly process of the nut structure, after the elastic member 21 is connected to the nut body 10, the protective member 22 can be pressed from the side of the elastic member 21 close to the first end S1, in the direction from the first end S1 to the second end S2, so that the second protrusion 222 of the protective member 22 abuts against the side of the first protrusion 12 axially close to the second end S2, thereby realizing the connection between the protective member 22 and the nut body 10. Compared with using other methods to connect the protective member 22 and the nut body 10, the difficulty of connecting the protective member 22 and the nut body 10 can be reduced.

[0103] In the above scheme, a first protrusion 12 is provided on the outer peripheral side of the nut body 10, the first protrusion 12 is provided close to the first end S1, and a second protrusion 222 is provided on the side of the main body 221 of the protective member 22 close to the nut body 10, at least part of the second protrusion 222 abuts against the first protrusion 12 from the side of the first protrusion 12 axially close to the second end S2. On the one hand, the first protrusion 12 can work together with the elastic member 21 to limit the protective member 22, improve the stability of the protective member 22, and enable the nut body 10 to move axially relative to the protective member 22 in the direction from the second end S2 to the first end S1. On the other hand, it can also reduce the difficulty of connecting the nut body 10 and the protective member 22, thereby improving the assembly efficiency of the nut structure.

[0104] Please continue reading Figure 6 In some embodiments, in the direction from the second end S2 to the first end S1, the width of the second protrusion 222 along the radial direction of the threaded hole 11 tends to decrease.

[0105] The width of the second protrusion 222 decreases in the direction from the second end S2 to the first end S1. At this time, the second protrusion 222 can be approximately inverted cone shape. When the nut body 10 cooperates with the bolt structure 40 to lock at least two workpieces 30 to be locked, the movable space K1 between the first end S1 of the nut body 10 and the surface of the workpiece 30 to be locked can be approximately in a right trapezoid shape. During the axial movement of the nut body 10, the side surface of the second protrusion 222 close to the nut body 10 along the radial direction of the threaded hole 11 is not easy to interfere with the nut body 10.

[0106] In the above scheme, the width of the second protrusion 222 is set to decrease in the direction from the second end S2 to the first end S1, which can reduce the risk of position interference between the nut body 10 and the second protrusion 222 when the nut body 10 moves axially within the range corresponding to the active space K1, thereby improving the reliability of the nut structure.

[0107] It can be understood that when the width of the second protrusion 222 tends to decrease in the direction from the second end S2 to the first end S1, the structural strength of the second protrusion 222 tends to decrease in the direction from the second end S2 to the first end S1. Therefore, when the part of the second protrusion 222 axially close to the second end S2 abuts against the first protrusion 12 from the side of the first protrusion 12 axially close to the second end S2, the reliability of the second protrusion 222 abutting against the first protrusion 12 can be improved.

[0108] See also Figure 4-Figure 6 In some embodiments, in the direction from the second end S2 to the first end S1 , the elastic member 21 is inclined toward a side away from the nut body 10 .

[0109] Specifically, in the direction from the second end S2 to the first end S1, the elastic member 21 is inclined toward the side away from the nut body 10. At this time, the minimum distance from the elastic member 21 to the nut body 10 along the radial direction of the threaded hole 11 tends to increase along the direction from the second end S2 to the first end S1, so that there is a larger distance between the side of the elastic member 21 close to the first end S1 and the second protrusion 222 of the protective member 22, which can reduce the influence of the axial force on the elastic member 21 on the second protrusion 222.

[0110] In the above scheme, the elastic member 21 is inclined toward the side away from the nut body 10 in the direction from the second end S2 to the first end S1, which can increase the distance from the contact point between the elastic member 21 and the protective member 22 to the second protrusion 222, reduce the influence of the axial force exerted on the elastic member 21 on the second protrusion 222, and improve the connection reliability between the second protrusion 222 and the first protrusion 12 of the nut body 10.

[0111] Please continue reading Figure 6 In some embodiments, in the axial direction, a height H1 of the elastic member 21 is greater than a height H2 of a portion of the protective member 22 that protrudes relative to the first end S1 .

[0112] Specifically, since the axial height of the protruding portion of the protective member 22 relative to the first end S1 is the axial height of the active space K1 between the first end S1 of the nut body 10 and the workpiece to be locked 30, the axial height of the elastic member 21 is greater than the axial height of the protruding portion of the protective member 22 relative to the first end S1, that is, the axial height of the elastic member 21 is greater than the height of the active space K1. Therefore, when the elastic member 21 is deformed along the axial direction, the nut body 10 can fully move within the range corresponding to the active space K1 to fully adjust the height of the nut structure.

[0113] In the above scheme, by setting the axial height of the elastic member 21 to be greater than the axial height of the protruding portion of the protective member 22 relative to the first end S1, during the axial deformation of the elastic member 21, the nut body 10 can fully utilize the range corresponding to the active space K1 to move, thereby increasing the height adjustment range of the nut structure.

[0114] In some embodiments, the support assembly 20 is disposed around the circumference of the nut body 10 .

[0115] Specifically, when the support assembly 20 includes components such as the elastic member 21 , the protective member 22 , etc., the elastic member 21 , the protective member 22 , etc. can all be arranged around the circumference of the nut body 10 .

[0116] In the above solution, the support assembly 20 is disposed around the nut body 10 in the circumferential direction, which can improve the structural strength of the support assembly 20 and improve its support reliability for the nut body 10 .

[0117] See also Figure 7 and Figure 8 In some embodiments, the nut body 10 includes a flange portion 13 and a rod portion 14 disposed on one side of the flange portion 13, wherein the first end S1 is located at an end of the rod portion 14 away from the flange portion 13, and the threaded hole 11 passes through the flange portion 13 and the rod portion 14 respectively; the support assembly 20 is disposed on the outer peripheral side of the rod portion 14, and the support assembly 20 contacts the flange portion 13 along the side axially away from the first end S1.

[0118] In the nut body 10, the flange portion 13 is a component used to disperse the stress of the nut body 10 during the tightening process and to improve the service life of the nut body 10, and the rod portion 14 is a main component of the nut body 10 for threaded connection with the bolt structure 40. The flange portion 13 and the rod portion 14 are arranged in sequence along the axial direction, wherein the end of the flange portion 13 away from the rod portion 14 along the axial direction is the second end S2 of the nut body 10, and the end of the rod portion 14 away from the flange portion 13 along the axial direction is the first end S1 of the nut body 10.

[0119] The threaded holes 11 penetrate the flange portion 13 and the rod portion 14 respectively. When the nut body 10 cooperates with the bolt structure 40 to lock at least two workpieces 30 to be locked, the bolt structure 40 can be threadedly connected to the threaded holes 11 corresponding to the rod portion 14, or can be further extended into the flange portion 13 and threadedly connected to the threaded holes 11 corresponding to the flange portion 13.

[0120] It can be understood that the flange portion 13 has a larger radial dimension relative to the rod portion 14, and it can protrude radially relative to the edge of the rod portion 14, and the orthographic projection of the rod portion 14 in a plane perpendicular to the axial direction is located within the orthographic projection of the flange portion 13 in a plane perpendicular to the axial direction. Among them, the contour shape of the orthographic projection of the flange portion 13 in a plane perpendicular to the axial direction can be various, for example, the contour shape of the orthographic projection of the flange portion 13 in a plane perpendicular to the axial direction can be circular or hexagonal. The shape of the orthographic projection of the rod portion 14 in a plane perpendicular to the axial direction can be a circular ring.

[0121] The support assembly 20 is provided with an outer peripheral side of the rod portion 14, and the side of the support assembly 20 axially away from the first end S1 is the side thereof axially close to the flange portion 13, and this side can be in contact with the flange portion 13. Therefore, when the bolt structure 40 applies an axial force to the nut body 10, the axial force can be directly transmitted from the flange portion 13 to the support assembly 20, and the flange portion 13 is equivalent to squeezing the support assembly 20 in the direction from the second end S2 to the first end S1, so that the elastic member 21 of the support assembly 20 is deformed along the axial direction.

[0122] In the above scheme, by arranging the support component 20 on the outer peripheral side of the rod portion 14, the side of the support component 20 axially away from the first end S1 is in contact with the flange portion 13. Therefore, when an axial force is applied to the nut body 10 through the bolt structure 40, the flange portion 13 can axially squeeze the support component 20 and directly transmit the axial force to the support component 20 in the axial direction, so that the elastic member 21 of the support component 20 is deformed in the axial direction. On the one hand, it can reduce the risk of the axial force being decomposed in other directions during the transmission process and reduce the difficulty of the elastic member 21 being deformed in the axial direction. On the other hand, it can improve the connection reliability of the support component 20 and the nut body 10 and reduce the risk of cracks or even separation at the connection portion of the support component 20 and the nut body 10 during the deformation of the elastic member 21.

[0123] Please continue reading Figure 8 In some embodiments, the support assembly 20 further includes a connecting member 23 connected to the elastic member 21 , the connecting member 23 extends radially along the threaded hole 11 , and is located between the elastic member 21 and the flange portion 13 , and the connecting member 23 contacts the flange portion 13 .

[0124] The connecting member 23 is a component for connecting the elastic member 21 and the nut body 10, and the connecting member 23 may be in the shape of a plate, and extends radially along the threaded hole 11. There are many ways to connect the connecting member 23 and the elastic member 21, for example, the connecting member 23 may be connected to the elastic member 21 by welding, or the connecting member 23 and the elastic member 21 may be an integrally formed structure.

[0125] The connecting piece 23 is axially located between the elastic piece 21 and the flange portion 13, and its side surface axially away from the elastic piece 21 contacts the side surface of the flange portion 13 axially close to the elastic piece 21, which can increase the contact area compared to direct contact with the flange portion 13 through the elastic piece 21.

[0126] Optionally, the elastic member 21 may be connected to a side of the connecting member 23 radially away from the rod portion 14 , which can reduce the risk of damaging the rod portion 14 when the elastic member 21 is deformed.

[0127] In the above scheme, by arranging a connecting member 23 between the elastic member 21 and the flange portion 13, the connecting member 23 extends radially along the threaded hole 11 and contacts the flange portion 13, thereby increasing the contact area between the flange portion 13 and the support assembly 20 and reducing the risk of damage to the flange portion 13 and the support assembly 20 during the process of transmitting axial force.

[0128] Optionally, when the support assembly 20 includes a protective member 22, the distance from the side of the protective member 22 radially away from the nut body 10 to the center of the threaded hole 11 can be greater than the sum of the radial width of the connecting member 23 and the length of the elastic member 21, thereby reducing the risk of the elastic member 21 protruding relative to the protective member 22 after deformation, thereby improving the protective effect of the protective member 22.

[0129] In a second aspect, an embodiment of the present application provides a locking device, comprising a bolt structure 40 and a nut structure as described in any one of the above items, wherein the bolt structure 40 is threadedly connected to a nut body 10 of the nut structure.

[0131] In a fourth aspect, an embodiment of the present application provides an electrical device, comprising the battery device 100 described above.

[0132] In some embodiments, the embodiments of the present application provide a nut structure, including a nut body 10 and a support assembly 20, wherein the nut body 10 is provided with a threaded hole 11, and the nut body 10 includes a first end S1 and a second end S2 which are arranged opposite to each other along the axial direction of the threaded hole 11, and the first end S1 is used to face the workpiece 30 to be locked; the support assembly 20 is arranged on the outer peripheral side of the nut body 10, and the support assembly 20 includes an elastic member 21 which is used to deform along the axial direction, and one side of the support assembly 20 along the axial direction is convex relative to the first end S1 of the nut body 10, so as to suspend the nut body 10. The support assembly 20 also includes a protective member 22, which is arranged on a side of the elastic member 21 close to the first end S1, and the side of the protective member 22 along the axial direction away from the elastic member 21 is convex relative to the first end S1 of the nut body 10. The outer peripheral side of the nut body 10 is provided with a first protrusion 12, and the first protrusion 12 is arranged close to the first end S1. The protective member 22 includes a main body 221 and a second protrusion 222 arranged on a side of the main body 221 close to the nut body 10, and at least part of the second protrusion 222 abuts against the first protrusion 12 from the first protrusion 12 along the axial direction close to the second end S2. In the direction from the second end S2 to the first end S1, the width of the second protrusion 222 along the radial direction of the threaded hole 11 tends to decrease. In the direction from the second end S2 to the first end S1, the elastic member 21 is inclined toward the side away from the nut body 10. In the axial direction, the height of the elastic member 21 is greater than the height of the protruding portion of the protective member 22 relative to the first end S1. The support assembly 20 is arranged around the circumference of the nut body 10. The nut body 10 includes a flange portion 13 and a rod portion 14 disposed on one side of the flange portion 13, wherein the first end S1 is located at an end of the rod portion 14 away from the flange portion 13, and the threaded hole 11 passes through the flange portion 13 and the rod portion 14 respectively; the support assembly 20 is disposed on the outer peripheral side of the rod portion 14, and the support assembly 20 is in contact with the flange portion 13 along the side away from the first end S1 in the axial direction. The support assembly 20 also includes a connecting member 23 connected to the elastic member 21, the connecting member 23 extends along the radial direction of the threaded hole 11, and is located between the elastic member 21 and the flange portion 13, and the connecting member 23 is in contact with the flange portion 13.
