[0033] Please refer to Figure 1 , Figure 1 which is a schematic structural diagram of an embodiment of the nut box provided by the present application. The present application provides a nut box 100. The nut box 100 includes a seat body 10 and a nut main body 20. Among them, the seat body 10 is a component for accommodating and protecting the nut main body 20, and the nut main body 20 is a fastener for installing a connecting component on the vehicle body main body.

The pressing portion 13 is provided with a first through hole 13a communicating with the accommodating space 10a.

[0035] Please also read Figure 2 , Figure 2 It is a structural schematic diagram of the nut column of the nut box provided in the present application. The nut body 20 includes a substrate 21 and a nut column 22 connected to the substrate 21. In some embodiments, the nut body 20 has a first mounting hole 20a, and the first mounting hole 20a extends from one end of the nut column 22 away from the substrate 21 to the side of the substrate 21 away from the nut column 22. The connecting component of the vehicle is provided with a second mounting hole. The first mounting hole 20a of the nut body 20 and the second mounting hole of the connecting component are used to cooperate with the fixing component to install the connecting component on the body of the vehicle. The fixing component can be a bolt, a stud, etc., but is not limited thereto.

[0036] The substrate 21 is located on the side of the support portion 11 facing the pressing portion 13, and the substrate 21 is at least partially disposed in the accommodation space 10a. The outer diameter of the nut column 22 is smaller than the hole diameter of the first through hole 13a, and the nut column 22 is at least partially accommodated in the first through hole 13a.

[0037] The side portion 12, the pressing portion 13 and the support portion 11 form an accommodating space 10a with a closed-loop side wall, and a first through hole 13a connected to the accommodating space 10a is opened on the pressing portion 13, and the substrate 21 is at least partially arranged in the accommodating space 10a, and the nut column 22 extends from the accommodating space 10a to the first through hole 13a. The closed-loop side wall formed by the support portion 11, the side portion 12 and the pressing portion 13 can be arranged to surround the substrate 21 on multiple sides to stably limit the substrate 21 in the accommodating space 10a, and the first through hole 13a can limit the displacement of the nut column 22. The closed-loop side wall of the accommodating space 10a and the first through hole 13a of the pressing portion 13 can play a good limiting role on the nut body 20, which can reduce the risk of the nut body 20 detaching from the seat body 10, and improve the connection strength between the nut body 20 and the seat body 10, thereby reducing the risk of loosening of the connecting parts of the vehicle due to the nut body 20 detaching from the seat body 10, thereby improving the reliability of the vehicle.

[0038] Please also read Figures 3 to 4 , Figure 3 It is a structural schematic diagram of an embodiment of a seat body of a nut box provided in the present application; Figure 4It is a schematic structural diagram of another embodiment of the base body of the nut box provided by this application. In some embodiments, the side portion 12 includes a first sub-side portion 121 and a second sub-side portion 122. The first sub-side portion 121 is connected between one side of the support portion 11 and one side of the pressing portion 13; the second sub-side portion 122 is opposite to and spaced from the first sub-side portion 121, and is connected between the other side of the support portion 11 and the other side of the pressing portion 13. The support portion 11, the first sub-side portion 121, the pressing portion 13, and the second sub-side portion 122 are sequentially connected end to end to form a receiving space 10a with a closed-loop side wall. After the substrate 21 is disposed in the receiving space 10a, the pressing portion 13 and the support portion 11 are relatively disposed on both sides of the substrate 21, and can limit the displacement of the substrate 21 along the arrangement direction of the pressing portion 13 and the support portion 11; the first sub-side portion 121 and the second sub-side portion 122 are relatively disposed on the other two sides of the substrate 21, and can limit the displacement of the substrate 21 along the arrangement direction of the first sub-side portion 121 and the second sub-side portion 122, effectively improving the limiting effect of the base on the nut body 20 and reducing the risk of the nut body 20 detaching from the base body 10.

[0039] In some embodiments, the support portion 11, the side portion 12, and the pressing portion 13 are integrally formed, and the side portion 12 is bent and formed relative to the support portion 11, and the pressing portion 13 is bent and formed relative to the side portion 12. Specifically, the first sub-side portion 121, the support portion 11, the second sub-side portion 122, and the pressing portion 13 may be an integrally formed structure. The first sub-side portion 121 is connected to one end of the support portion 11, the second sub-side portion 122 is connected to the other end of the support portion 11, the first sub-side portion 121 and the second sub-side portion 122 are relatively disposed, and extend toward the same side. The pressing portion 13 is connected to the end of the first sub-side portion 121 away from the support portion 11, and the pressing portion 13 can be bent toward the direction of the second sub-side portion 122.

[0040] The second sub-side portion 122, the support portion 11, the first sub-side portion 121, and the pressing portion 13 are sequentially connected in a non-detachable manner, that is, between the second sub-side portion 122 and the support portion 11, between the support portion 11 and the first sub-side portion 121, and between the first sub-side portion 121 and the pressing portion 13, they are connected in a non-detachable manner. The second sub-side portion 122 and the pressing portion 13 are connected in a detachable manner. In some embodiments, a first fastening portion 131 is provided at one end of the pressing portion 13 close to the second sub-side portion 122, and a second fastening portion 1221 is provided at one end of the second sub-side portion 122 close to the pressing portion 13, and the first fastening portion 131 is connected to the second fastening portion 1221.

[0041] Please refer to Figure 5 , Figure 5It is a schematic cross-sectional structure diagram of another embodiment of the base body of the nut box provided by this application. In some embodiments, deformation can occur between the pressing portion 13 and the first sub-side portion 121. When the nut body 20 is not provided in the accommodation space 10a, the pressing portion 13 can extend in a direction away from the supporting portion 11 from the end of the first sub-side portion 121 away from the supporting portion 11. When the nut body 20 is disposed in the accommodation space 10a, the end of the pressing portion 13 connected to the first sub-side portion 121 can be bent toward the second sub-side portion 122 to cover the side of the substrate 21 facing away from the supporting portion 11. At the same time, the nut post 22 is accommodated in the first through hole 13a, and then the first fastening portion 131 of the pressing portion 13 is connected to the second fastening portion 1221 of the second sub-side portion 122, and the assembly between the nut body 20 and the base body 10 can be completed. It can omit the complex welding process and does not require tools such as wrenches to complete the assembly, which can not only improve the assembly efficiency but also enhance the connection strength between the nut body 20 and the base body 10.

[0042] In some embodiments, the first fastening portion 131 includes a clamping hole, and at least a part of the second fastening portion 1221 is disposed in the clamping hole and is in interference connection with the clamping hole. The second fastening portion 1221 can be an elastic clamping block. During the connection between the second sub-side portion 122 and the pressing portion 13, only the clamping hole of the pressing portion 13 needs to be aligned with the clamping block of the second sub-side portion 122, and then the pressing portion 13 is pressed to make the clamping block contract and be clamped in the clamping hole. After the second fastening portion 1221 enters the clamping hole, it restores deformation and presses the inner wall of the clamping hole, thereby completing the connection between the second sub-side portion 122 and the pressing portion 13, which can enhance the connection strength and improve the connection efficiency between the second sub-side portion 122 and the pressing portion 13.

[0043] In some embodiments, a first magnetic attracting member (not shown in the figure) is embedded on the inner wall surface of the clamping hole, and a second magnetic attracting member (not shown in the figure) is provided on the surface of the second fastening portion 1221. When the second fastening portion 1221 is clamped in the clamping hole, the first magnetic attracting member and the second magnetic attracting member attract each other, which can further enhance the connection strength between the second sub-side portion 122 and the pressing portion 13 and effectively reduce the risk of the nut body 20 detaching from the base body 10.

[0044] Please continue to refer to Figures 1 to 2 and at the same time refer to Figure 6 Figure 6 ​It is a schematic structural diagram of another embodiment of the nut box provided by this application. In some embodiments, the base plate 21 and the surface of the side portion 12 facing the accommodation space 10a are connected with interference fit. On the one hand, it can increase the contact area between the base plate 21 and the surface of the side portion 12 facing the accommodation space 10a, thereby increasing the friction force, so that during the process of the fixing component cooperating with the nut body 20 to install the connecting component on the vehicle body main body, the relative sliding between the seat body 10 and the nut body 20 can be reduced, so that the torque can be transmitted to the fixing component more directly and efficiently, and the installation strength and installation effect of the connecting component installed on the vehicle body main body can be improved; on the other hand, through the interference fit between the base plate 21 and the surface of the side portion 12 facing the accommodation space 10a, it can also reduce the risks such as the loosening of the seat body 10 or the nut body 20 and the separation of the nut body 20 from the seat body 10 caused by factors such as vibration and impact, and can further enhance the connection strength and stability between the nut main body and the seat body 10, so that the reliability of the vehicle is further improved.

[0045] In some embodiments, the second sub-side portion 122 and the first sub-side portion 121 are opposite and spaced apart along the first direction X-X, and the support portion 11 and the pressing portion 13 are opposite and spaced apart along the second direction Z-Z. Wherein, the second direction Z-Z is perpendicular to the first direction X-X. In the first direction X-X, the first sub-side portion 121 is connected between one side of the support portion 11 and one side of the pressing portion 13; the second sub-side portion 122 is connected between the other side of the support portion 11 and the other side of the pressing portion 13. When the nut body 20 is arranged in the accommodation space 10a, the second sub-side portion 122 and the first sub-side portion 121 are used to limit the displacement of the nut body 20 along the first direction X-X, and the support portion 11 and the pressing portion 13 are used to limit the displacement of the nut body 20 along the second direction Z-Z, effectively improving the limiting effect of the base on the nut body 20 and reducing the risk of the nut body 20 detaching from the seat body 10.

[0046] In some embodiments, the outer edge of the base plate 21 is provided with a first abutting portion 211 and a second abutting portion 212 arranged at intervals along the first direction X-X. The first abutting portion 211 is connected with interference fit to the surface of the first sub-side portion 121 facing the accommodation space 10a, and the second abutting portion 212 is connected with interference fit to the surface of the second sub-side portion 122 facing the accommodation space 10a.

[0047] By press-fitting the first abutting portion 211 with the surface of the first sub-side portion 121 facing the accommodation space 10a, and press-fitting the second abutting portion 212 with the surface of the second sub-side portion 122 facing the accommodation space 10a, on the one hand, risks such as loosening of the seat body 10 or the nut body 20 and detachment of the nut body 20 from the seat body 10 caused by factors such as vibration and impact can be reduced, and the connection strength and stability between the female body and the seat body 10 can be enhanced; on the other hand, during the process of the fixing member cooperating with the nut body 20 to install the connecting member on the vehicle body main body, an interference amount is generated between the first abutting portion 211 and the surface of the first sub-side portion 121 facing the accommodation space 10a and between the second abutting portion 212 and the surface of the second sub-side portion 122 facing the accommodation space 10a. The generated interference amount will generate a radial pressing force on the nut body 20, and this pressing force will be converted into the frictional force between the nut body 20 and the fixing member, thereby improving the torque transmission efficiency.

[0048] In some embodiments, please continue to refer to Figure 2 and Figure 6 , the substrate 21 includes a square substrate 21. A pair of corners of the square substrate 21 serve as the first abutting portion 211 and the second abutting portion 212 respectively. The square substrate 21 includes a first end portion 213 and a second end portion 214 which are oppositely arranged. The first abutting portion 211 is located at one end of the first end portion 213, and the second abutting portion 212 is located at one end of the second end portion 214 far from the first abutting portion 211.

[0049] The vertical distance between the first end portion 213 and the second end portion 214 is smaller than the size of the accommodation space 10a along the first direction X-X, that is, the size of the square substrate 21 in the arrangement direction of the first end portion 213 and the second end portion 214 is smaller than the distance between the first sub-side portion 121 and the second sub-side portion 122 along the first direction X-X. During the process of disposing the square substrate 21 in the accommodation space 10a, only by corresponding the first end portion 213 with the first sub-side portion 121 and the second end portion 214 with the second sub-side portion 122, the square substrate 21 can be smoothly disposed in the accommodation space 10a. Then, the pressing portion 13 can be connected to one end of the first sub-side portion 121 and bent toward the direction of the second sub-side portion 122, and the first fastening portion 131 of the pressing portion 13 can be connected to the second fastening portion 1221 of the second sub-side portion 122, and thus the assembly between the nut body 20 and the seat body 10 can be completed, thereby further improving the assembly efficiency between the nut body 20 and the seat body 10.

[0050] When the first end portion 213 corresponds to the first sub-side portion 121 and the second end portion 214 corresponds to the second sub-side portion 122, the first end portion 213 and the second end portion 214 are oppositely arranged along the first direction X-X, and the diagonal line where the first abutting portion 211 and the second abutting portion 212 are located is inclined with respect to the first direction X-X.

[0051] In some embodiments, both the first sub-side portion 121 and the second sub-side portion 122 are deformable portions. When the square substrate 21 is not provided in the accommodation space 10a, the dimension of the accommodation space 10a along the first direction X-X is smaller than the length of the diagonal of the square substrate 21. That is, the distance between the first sub-side portion 121 and the second sub-side portion 122 along the first direction X-X is smaller than the distance between the first abutting portion 211 and the second abutting portion 212 along the diagonal, so that the first abutting portion 211 can squeeze the surface of the first sub-side portion 121 facing the accommodation space 10a to achieve an interference connection with the first sub-side portion 121, and the second abutting portion 212 can squeeze the surface of the second sub-side portion 122 facing the accommodation space to achieve an interference connection with the second sub-side portion 122.

[0052] Since the dimension of the accommodation space 10a along the first direction X-X is smaller than the length of the diagonal of the square substrate 21 when the square substrate 21 is not provided in the accommodation space 10a, and both the first sub-side portion 121 and the second sub-side portion 122 are deformable portions, during the process of the fixing member cooperating with the nut body 20 to install the connecting member on the vehicle body main body, the nut body 20 can rotate a preset angle under the drive of the fixing member. During the rotation of the nut body 20 relative to the seat body 10, as the torque increases, the first abutting portion 211 and the second abutting portion 212 can squeeze the first sub-side portion 121 and the second sub-side portion 122, so that the first sub-side portion 121 and the second sub-side portion 122 expand in a direction away from the accommodation space 10a. Since the connection between the pressing portion 13 and the second sub-side portion 122 is reliable, the first sub-side portion 121 and the second sub-side portion 122 form a tensile structure during the expansion process, which can bear a greater torque, so that the fixing member generates a greater pressing force, thereby improving the connection strength.

[0053] In addition, by enabling the nut body 20 to rotate a preset angle in the accommodation space 10a under the drive of the fixing member, on the one hand, it can reduce the unnecessary friction between the nut body 20 and the seat body 10 to a certain extent, so that the torque is transmitted to the fixing member more directly and efficiently; on the other hand, a pressing force will be generated during the cooperation between the nut body 20 and the fixing member. Allowing the nut body 20 to rotate a preset angle in the accommodation space 10a helps to evenly distribute this pressing force during the process of tightening the fixing member, and can avoid stress concentration, thereby improving the reliability and durability of the connection.

[0054] In some embodiments, the substrate 21 further includes a circular substrate 21, a rhombic substrate 21 or an elliptical substrate 21, but is not limited thereto.

[0055] In some embodiments, along the axial direction of the nut post 22, the dimension from the side of the base plate 21 facing away to the end of the nut post 22 facing away from the base plate 21 is the first dimension; along the first direction X-X, the dimension from the surface of the support portion 11 facing the accommodation space 10a to the surface of the pressing portion 13 facing away from the accommodation space 10a is the second dimension, wherein the first dimension is greater than or equal to the second dimension. If the first dimension is equal to the second dimension, the end face of the nut post 22 facing away from the base plate 21 is flush with the surface of the pressing portion 13 facing away from the accommodation space 10a; if the first dimension is greater than the second dimension, the end face of the nut post 22 facing away from the base plate 21 protrudes from the surface of the pressing portion 13 facing away from the accommodation space 10a.

[0056] Please refer to Figure 7 , Figure 7 FIG. is a schematic structural view of the third embodiment of the base body of the nut box provided by the present application. In some embodiments, the support portion 11 is provided with a second through hole 11a. The inner diameter of the second through hole 11a is greater than that of the fixing member, and the second through hole 11a is for the fixing member to pass through.

[0057] A support tongue 111 extending toward the accommodation space 10a and inclined in the direction of the pressing portion 13 is provided on the outer periphery of the second through hole 11a. One end of the support tongue 111 away from the second through hole 11a protrudes from the plane where the support portion 11 is located. The support tongue 111 is used to support the base plate 21, so that a gap 112 is formed between the base plate 21 and the support portion 11. The gap 112 between the base plate 21 and the support portion 11 is for accommodating electrophoresis solution during the electrophoresis process. After the electrophoresis solution is dried, it will adhere to the surface of the base plate 21 facing the support portion 11 and the surface of the support portion 11 facing the base plate 21, and the gap 112 is exposed to prevent sticking between the base plate 21 and the support portion 11.

[0058] In some embodiments, the support portion 11 is provided with two extension holes 11b communicating with the second through hole 11a. The two extension holes 11b are relatively arranged on both sides of the second through hole 11a. The support tongue 111 includes a first support tongue 1111 and a second support tongue 1112. One of the first support tongue 1111 and the second support tongue 1112 is arranged at the edge of one extension hole 11b opposite to the second through hole 11a, and the other of the first support tongue 1111 and the second support tongue 1112 is arranged at the edge of the other extension hole 11b opposite to the second through hole 11a. The first support tongue 1111 and the second support tongue 1112 are relatively arranged, and both the first support tongue 1111 and the second support tongue 1112 extend in the direction of approaching each other and are inclined in the direction of the pressing portion 13.

[0059] By forming two extending holes 11b and disposing the first supporting tongue 1111 and the second supporting tongue 1112 at the edges of the two extending holes 11b opposite to the second through hole 11a respectively, the arrangement of the first supporting tongue 1111 and the second supporting tongue 1112 will not hinder the fixing component from passing through the second through hole 11a.

[0060] In some embodiments, the supporting part 11 is further provided with at least two third mounting holes 11c. A part of the at least two third mounting holes 11c is disposed on one side of the second through hole 11a along the third direction Y-Y, and another part of the at least two third mounting holes 11c is disposed on the other side of the second through hole 11a along the third direction Y-Y. The plurality of third mounting holes 11c are not communicated with the second through hole 11a, and the third mounting holes 11c are used to cooperate with the mounting component to fix the nut box 100 to the connecting component or the vehicle body main body. Wherein, the third direction Y-Y is perpendicular to the first direction X-X and the second direction Z-Z.

[0061] This application also provides a vehicle including the nut box 100 in any of the above embodiments. The vehicle further includes a fixing component and a connecting component. The nut box 100 is used to cooperate with the fixing component and the connecting component to mount the connecting component on the vehicle body main body. Wherein, the connecting component can be a seat, a battery device, a car door, etc., but is not limited thereto; the fixing component can be a bolt, a stud, etc., but is not limited thereto.
