[0036] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative efforts fall within the protection scope of the present application

[0037] The embodiments of the present application provide a base, a leaf spring nut assembly and a vehicle. Please refer to Figure 1 and Figure 2 , Figure 1 which is the overall structural schematic diagram of the first state of the leaf spring nut assembly provided by the embodiments of the present application Figure 2 which is the overall structural schematic diagram of the second state of the leaf spring nut assembly provided by the embodiments of the present application

[0038] Among them, the base 10 is a component structure of the leaf spring nut assembly. The leaf spring nut assembly may include the base 10 and a leaf spring nut. During assembly, the leaf spring nut is pushed towards the base 10, and the leaf spring nut clamps the base 10. Passing a bolt or a screw rod (not shown in the figure) through the leaf spring nut and the base 10 can achieve fastening. It can be seen that Figure 1 in Figure 2 the base 10 and the leaf spring nut are in a separated state,

[0039] in the base 10 and the leaf spring nut are in an assembled state. When the leaf spring nut is being assembled with the base 10, that is, when the base 10 and the leaf spring nut change from the separated state to the assembled state, it is easy to scratch the base platform 11 of the base 10, reducing the assembly efficiency. Scratching the base platform by the leaf spring nut will also cause the problem of glue shaving. The shaved glue is difficult to clean up, and it will also affect the assembly of other places. To solve the above problems, according to the first aspect of the present disclosure, the embodiments of the present application provide a base 10, which can be used for assembling with a leaf spring nut

[0040] Please combine with Figure 1 and Figure 3 , the base 10 includes a base platform 11, and the base platform 11 is provided with a first mounting hole 12, and the first mounting hole 12 is disposed opposite to the third mounting hole 44 of the leaf spring nut. In the embodiment of the present application, when the base 10 and the leaf spring nut are assembled, the first mounting hole 12 of the base platform 11 is disposed opposite to the third mounting hole 44 of the leaf spring nut, so as to facilitate the penetration and fastening of the fastener. The fastener may include a bolt, etc., and the fastener penetrates through the first mounting hole 12 and the third mounting hole 44 and is screwed with the leaf spring nut, so as to fasten the base 10 and the leaf spring nut.

[0041] When assembling the base platform 11 and the leaf spring nut, the elastic piece 40 is likely to scrape the base platform 11, causing deburring. Please combine with Figure 1 , Figure 3 and Figure 4 , to avoid the elastic piece 40 scraping the base platform 11, the base 10 further includes a convex platform 13. By providing the convex platform 13 on one side of the base platform 11, the convex platform 13 is spaced from the first mounting hole 12 to facilitate the penetration and fastening of the fastener. The convex platform 13 further includes a first surface 131 facing away from the base platform 11. Understandably, the convex platform 13 protrudes from the base platform 11, and the first surface 131 of the convex platform 13 also protrudes from the base platform 11. During the assembly process of the base 10 and the leaf spring nut, the first surface 131 is used to abut against the elastic piece 40 of the leaf spring nut, so that the elastic piece 40 is spaced from the base platform 11.

[0042] In the embodiment of the present application, a protruding convex platform 13 is provided on the base platform 11, that is, the first surface 131 of the convex platform 13 is spaced from the base platform 11. During the assembly process of the base 10 and the leaf spring nut, the first surface 131 of the convex platform 13 can abut against the elastic piece 40 of the leaf spring nut, so that during the assembly process of the base 10 and the leaf spring nut, the elastic piece 40 of the leaf spring nut is spaced from the surface of the base platform 11. Thus, the elastic piece 40 will not scrape the surface of the base platform 11, solving the problem of reduced assembly efficiency caused by the elastic piece 40 scraping the base platform 11, and also solving the problem of deburring caused by the elastic piece 40 scraping the base platform 11.

[0043] Please combine with Figure 1 , Figure 3 and Figure 4, in some embodiments, a first inclined surface 133 is provided on a side of the boss 13 facing away from the first mounting hole 12. The first inclined surface 133 is used to guide the elastic sheet 40, and the extending direction of the first inclined surface 133 is: the first inclined surface 133 extends from the first surface 131 along a direction close to the base 11 and away from the first mounting hole 12. Thus, when the elastic sheet 40 contacts the first inclined surface 133, the first inclined surface 133 can guide the elastic sheet 40 to the first surface 131, and the first inclined surface 133 can also reduce the resistance of the elastic sheet 40 during the traveling process.

[0044] According to the second aspect of the present disclosure, an embodiment of the present application provides a leaf spring nut assembly, which includes all the beneficial effects of the above-mentioned base 10, and the present disclosure will not repeat them here.

[0045] The leaf spring nut assembly further includes a leaf spring nut, which can be assembled with the base 10 and fastened by a fastener, such as a bolt or a screw, etc. During assembly, the leaf spring nut is pushed towards the base 10, and the elastic sheet 40 cooperates with the second clamping portion 33 of the leaf spring nut to clamp the base 10, and the bolt or the screw is passed through the first clamping portion, the elastic sheet, and the second clamping portion to achieve fastening.

[0046] Please refer to Figure 2 and Figure 5 , wherein, the leaf spring nut includes a clamping member 30, the clamping member 30 is provided with a clamping space 36, and at least a part of the base 10 is located in the clamping space 36 to facilitate fastening the base 10 and the clamping member 30.

[0047] The leaf spring nut may further include a nut body 50, the nut body 50 is connected to the clamping member 30, and the nut body 50 and the clamping member 30 may be integrally formed. For example, a nut hole may be punched out from the clamping member 30, and then threads may be tapped in the nut hole, so that the leaf spring nut can better fasten thin plate workpieces that are difficult or impossible to firmly hold the nut by hand and difficult or impossible to weld the nut.

[0048] The leaf spring nut further includes an elastic sheet 40, the elastic sheet 40 is connected to the clamping member 30, at least a part of the elastic sheet 40 is located in the clamping space 36, and the elastic sheet 40 is used to cooperate with the clamping member 30 to clamp the base 10. The elastic sheet has good elasticity and can have good mobility when being squeezed, so as to facilitate assembly with bases 10 of different thicknesses. The elastic sheet 40 cooperates with the second clamping portion of the clamping member 30 to generate a lasting clamping force on the base 10 placed therein, and at the same time, the elastic sheet can apply force evenly to play a role in fastening and locking the fixed parts. In the embodiment of the present application, during the assembly process of the base 10 and the leaf spring nut, the elastic sheet 40 abuts against the first surface 131 of the base 10, so that the elastic sheet 40 is spaced apart from the base 11.

[0049] The leaf spring nut assembly provided in the embodiment of the present application includes a base 10 and a leaf spring nut, and a protruding boss 13 is provided on the base 11, that is, the first surface of the boss 13 is spaced apart from the base 11. During the assembly process of the base 10 and the leaf spring nut, the first surface 131 of the boss 13 can abut against the elastic sheet 40 of the leaf spring nut, so that the elastic sheet 40 of the leaf spring nut is spaced apart from the surface of the base 11, so that the elastic sheet will not scratch the surface of the base 11 and will not cause rubber chipping.

[0050] Please combine Figure 6 In some embodiments, a first inclined surface 133 is provided on a side of the boss 13 away from the first mounting hole 12. The first inclined surface 133 extends from the first surface 131 in a direction close to the base 11 and away from the first mounting hole 12. The elastic sheet 40 includes a second inclined surface 401 opposite to the first inclined surface 133. The second inclined surface 401 is adapted to the first inclined surface 133 to guide the elastic sheet 40 from the first inclined surface 133 to the first surface 131.

[0051] Thus, when the elastic sheet 40 contacts the first inclined surface 133 , the first inclined surface 133 can cooperate with the second inclined surface 401 of the elastic sheet 40 to guide the elastic sheet 40 to the first surface 131 , and also reduce the scratch between the elastic sheet 40 and the first inclined surface 133 .

[0052] Please combine Figure 5 In some embodiments, the clamping member 30 includes a first clamping portion 31, a connecting portion 32 and a second clamping portion 33 connected in sequence, the first clamping portion 31 and the second clamping portion 33 are arranged opposite to each other, and the first clamping portion 31, the connecting portion 32 and the second clamping portion 33 form a clamping space 36; one end of the second clamping portion 33 away from the connecting portion 32 is bent in a direction away from the first clamping portion 31.

[0053] Specifically, one end of the connecting portion 32 is bent and connected to the first clamping portion 31, and the other end of the connecting portion 32 is bent and connected to the second clamping portion 33. The first clamping portion 31 and the second clamping portion 33 form a clamping space 36 and a clamping port connected to the clamping space, and the base 11 can be inserted into the clamping space through the clamping port. During installation, the clamping port is aligned with the base, and the leaf spring nut is inserted into the base, so that at least part of the base is located in the clamping space 36, so that the base is clamped and tightened.

[0054] The second clamping portion 33 of the clamping member 30 is bent at one end away from the connecting portion 32 in a direction away from the first clamping portion 31, which increases the distance between the end of the second clamping portion 33 away from the connecting portion 32 and the first clamping portion 31, thereby enlarging the opening formed by the end of the second clamping portion 33 away from the connecting portion 32 and the first clamping portion 31, and facilitating the use of tools to increase the distance between the first clamping portion 31 and the second clamping portion 33, thereby facilitating the installation and disassembly of the base 10 and the leaf spring nut.

[0055] Please combine with Figure 5 , wherein, the nut body 50 can be disposed on the side of the second clamping portion 33 away from the first clamping portion 31. The first clamping portion is provided with an elastic piece 40, and one end of the elastic piece is connected to the first clamping portion 31 and approaches the second clamping portion 33.

[0056] In some embodiments, the nut body 50 may include a cylindrical portion 51 and a frustum portion 53 fixedly connected to the end face of the cylindrical portion. One end of the frustum portion 53 away from the cylindrical portion 51 is fixedly connected to the side of the second clamping portion 33 away from the first clamping portion 31.

[0057] In some embodiments, the elastic piece 40 may be formed by stamping the first clamping portion.

[0058] Please combine with Figure 6 , the elastic piece 40 includes a first extension portion 41 and a second extension portion 43. One end of the first extension portion 41 is connected to the first clamping portion 31. Wherein, the first clamping portion 31 may be provided with a second mounting hole, and one end of the first extension portion 41 may be connected to the edge of the second mounting hole. The second mounting hole may be a bolt hole.

[0059] The other end of the first extension portion 41 is located in the clamping space 36 and extends in the direction close to the second clamping portion 33. The second extension portion 43 is connected to the end of the first extension portion 41 away from the first clamping portion 31 and extends in the direction away from the second clamping portion 33. The second extension portion 43 is located in the clamping space 36, and an abutting portion 403 is formed at the connection of the first extension portion 41 and the second extension portion 43.

[0060] Through the first extension portion 41 and the second extension portion 43, and the abutting portion 403 formed at the connection of the first extension portion 41 and the second extension portion 43, the elastic piece 40 has better elasticity, and the elastic piece 40 can cooperate with the clamping member 30 to clamp the base 10, having a better fastening effect.

[0061] Please combine with Figure 1 and Figure 6 , in some embodiments, the base 11 is provided with a first groove 113. The elastic piece 40 further includes an abutting portion 403. An abutting portion 403 is formed at the connection of the first extension portion 41 and the second extension portion 43. The minimum distance between the abutting portion 403 and the base 11 is less than the minimum distance between the second inclined surface 401 and the base, that is, the abutting portion 403 is closer to the base than the second inclined surface 401. The abutting portion 403 is closer to the first mounting hole 12 than the second inclined surface 401. When the second inclined surface 401 of the elastic piece 40 abuts against the first inclined surface 133, the abutting portion is located on the side of the second inclined surface 401 facing the first mounting hole 12, and the abutting portion 403 extends beyond the first surface 131 of the boss 13 and is located in the first groove 113.

[0062] The elastic piece 40 includes a second inclined surface 401 and is formed with an abutting portion 403, so that the elastic piece 40 and the clamping member 30 cooperate to have a better clamping effect on the base 10. Since the position of the abutting portion 403 is closer to the base 11 than the second inclined surface 401, and the abutting portion 403 is closer to the first mounting hole 12 than the second inclined surface 401, when the second inclined surface 401 of the elastic piece 40 abuts against the first inclined surface 133, during the process of guiding the elastic piece 40 from the first inclined surface 133 to the first surface 131, the abutting portion 403 is likely to scratch the base 11. To avoid the abutting portion 403 from scratching the base 11, a first groove 113 is provided on the base in the embodiment of the present application. In this way, when the second inclined surface 401 of the elastic piece 40 abuts against the first inclined surface 133, the abutting portion 403 extends beyond the first surface 131 of the boss and is located in the first groove 113, and the abutting portion 403 will not scratch the base 11.

[0063] To better avoid the abutting portion 403 from scratching the first groove 113, the abutting portion 403 is located in the first groove 113, and the abutting portion 403 should be spaced from the bottom wall and the side wall of the first groove. While avoiding the abutting portion 403 from scratching the first groove 113, the resistance during the assembly process of the abutting portion 403 is reduced, and a higher assembly efficiency can also be achieved.

[0064] Specifically, in some embodiments, the elastic piece 40 includes two support arms 431, and an abutting portion 403 is formed on one support arm 431 of the elastic piece 40. Two support arms 431 can form two abutting portions 403 in total; the base 11 is provided with two first grooves 113, and the two first grooves 113 are arranged along a direction perpendicular to the boss 13 to the first mounting hole 12, and one first groove 113 is provided on each of the opposite sides of the boss 13; when the second inclined surface 401 abuts against the first inclined surface 133, at least one abutting portion 403 extends beyond the first surface 131 and is located in one first groove 113.

[0065] The two support arms 431 form a third mounting hole 44 corresponding to the first mounting hole 12. The third mounting hole 44 is correspondingly arranged with the first mounting hole 12 opened on the base 11 to facilitate the penetration and fastening of the fastener. The hole wall of the third mounting hole 44 forms a second inclined surface 401. That is to say, during assembly, the second inclined surface 401 formed by the hole wall of the third mounting hole 44 cooperates with the first inclined surface 133 of the boss 13, so as to guide the elastic piece 40 from the first inclined surface 133 to the first surface 131. During this process, one support arm 431 of the elastic piece 40 cooperates with one first groove 113, so that the abutting portion 403 on this support arm 431 can enter the first groove 113, thereby effectively preventing the abutting portion 403 from scratching the base 11.

[0066] Specifically, the first groove body 113 extends along the first direction and communicates with the outside. When switching from the first state to the second state, one arm of the elastic sheet 40 enters the installation space 1015 from the first groove body 113.

[0067] The first extension part 41 and the second extension part 43 are formed with a third installation hole 44, which is correspondingly arranged with the first installation hole 12. The central axes of the first installation hole 12 and the third installation hole 44 may be located on the same straight line.

[0068] Please refer to Figure 1 and Figure 6 , in some embodiments, there are two abutting parts 403, and the third installation hole 44 is located between the two abutting parts 403. Along the direction perpendicular to the first extension part 41 to the second extension part 43, the distance between the opposite ends of the boss 13 is less than the distance between the two abutting parts 403. When assembling, the opposite ends of the boss 13 pass through between the two abutting parts 403 and abut against the hole wall of the third installation hole 44. Define the contact surface between the hole wall of the third installation hole 44 and the opposite ends of the boss 13 as the second inclined surface. It is easy to understand that the abutting part 403 is located at the connection of the first extension part 41 and the second extension part 43, and the second inclined surface is located on the second extension part 43.

[0069] In some embodiments, when the second inclined surface 401 of the elastic sheet 40 abuts against the first inclined surface 133 of the boss 13, the two abutting parts 403 are located on the opposite sides of the boss 13, and the abutting parts 403 are spaced apart from the boss 13.

[0070] Please refer to Figure 1 , in some embodiments, the base further includes a base side wall 1013. The base side wall 1013 protrudes from the periphery of the base 11 and forms an installation space 1015 with the base. The base side wall 1013 is provided with a first opening 1016, and the leaf spring nut is inserted into the installation space 1015 from the first opening 1016. Wherein, the first direction is from the first opening 1016 to the installation space, and the second direction is perpendicular to the first direction.

[0071] In these embodiments, the leaf spring nut is inserted into the installation space 1015 through the first opening 1016 of the base side wall 1013. The installation space 1015 formed by the base side wall 1013 and the base 11 can guide and limit the leaf spring nut, so as to improve the assembly efficiency of the leaf spring nut and the base 10.

[0072] In the embodiment of the present application, the first clamping portion 31 is inserted into the installation space 1015 from the first opening 1016 along the first direction, the second clamping portion 33 is located on the side of the base 11 away from the boss 13, the first groove body 113 can be provided with a first groove connected to the first opening 1016, the first groove body 113 can be extended along the first direction, and the two first groove bodies 113 can be arranged on opposite sides of the boss 13 along the second direction.

[0073] The elastic sheet 40 defines a third mounting hole 44 matching the first mounting hole. The hole wall of the third mounting hole 44 includes a second inclined surface 401 opposite to the first inclined surface. The second inclined surface 401 matches the first inclined surface 133 to guide the second extension portion 43 from the first inclined surface 133 to the first surface 131 .

[0074] When the elastic piece 40 abuts against the first surface 131 of the boss, two ends of the elastic piece extend beyond the first surface 131 of the boss and are located in the first groove.

[0075] In the embodiment of the present application, the boss 13 of the base starts to squeeze with the first clamping part 31 of the clamping member. When the leaf spring nut elastic sheet 40 contacts the boss 13, the elastic sheet 40 moves toward the direction close to the first clamping part 31 through the squeezing effect, and will not contact the surface of the base, thereby avoiding scraping glue. In addition, during the squeezing and upward movement of the elastic sheet 40, since the contact point between the elastic sheet and the boss 13 is not at the lowest point, the lowest point on both sides of the elastic sheet, that is, the position of the abutment 403 close to the second clamping part 33, still has the risk of contacting the surface of the base and scraping glue. Therefore, the first slot body 113 is provided, and the abutment 403 will pass through the first slot body 113 to avoid contact between the abutment 403 and the surface of the base, thereby reducing scraping glue.

[0076] According to a third aspect of the present disclosure, a vehicle is provided, the vehicle comprising the above-mentioned base or the leaf spring nut assembly.
