Description
Technical Field
[0001] The utility model relates to the technical field of vehicles, and particularly relates to a nut plate, a vehicle door and a vehicle. Background Art
[0002] With the rich and changeable overall styling styles of automobiles, the replacement cycle of automobile styling is faster, the average golden life cycle of a new car is shorter, and the design requirement for the generalization of automobile structures has become more urgent. Generalized design not only brings a shorter design cycle to the design, but also can ensure that the project plan of the automobile is completed on schedule or in advance, so as to ensure the smooth market launch of the vehicle model and seize the market share with competitors as soon as possible. At the same time, generalized design can also bring stability to automobile design. A mature and stable design structure often performs well in terms of durability after being tested by market vehicle models, and directly applying the structure to the new car design brings more mature experience. For the door structure, the generalization design of local positions is more involved in performance requirements. Door sag is a very important requirement for door performance and is the first performance to be considered in door design.
[0003] In the related art, the selection of door hinges is often directly selected from the design library, and the nut plates matched with them often have many different design structures according to different-shaped vehicle models. Such structures are not easy to meet the requirements of structural generalization. This solution considers the generalization of this structure from the structure of the nut plate. Summary of the Utility Model
[0004] The utility model aims to at least solve one of the technical problems existing in the prior art. For this reason, an object of the utility model is to provide a nut plate, which can increase the avoidance area for avoiding adjacent structures through its short side on the one hand, and can increase the force-bearing contact area with adjacent structures through its long side on the other hand, thereby improving its versatility when matching with vehicle doors of different shapes.
[0005] The utility model further provides a vehicle door.
[0006] The utility model further provides a vehicle.
[0007] According to the nut plate of the first aspect of the utility model, the nut plate is a polygonal plate and includes: two connecting edges arranged at intervals in a first direction; a short side and a long side arranged at intervals in a second direction. A nut hole is provided on one side of the nut plate close to the long side. Two ends of the short side are connected between the first ends of the two connecting edges, and two ends of the long side are connected between the second ends of the two connecting edges. The first direction is perpendicular to the second direction.
[0008] In the above technical solution, the connecting edge is connected between the short side and the long side. The length of the long side is greater than that of the short side. The long side can increase the force-bearing contact area between the nut plate and the matching structure, thereby improving the connection strength. The short side can, on the basis of ensuring the connection between the nut plate and the matching structure, increase the avoidance dimension of the nut plate for avoiding relevant structural shapes, thereby reducing the risk of structural interference, and further improving the reliability and versatility when the nut plate is matched with different vehicle doors. The nut hole is eccentrically arranged on the side of the nut plate close to the long side in the second direction. When the nut plate is installed with the matching structure, the force distribution can be made close to the long side, so that the connection force-bearing area can be increased, the force uniformity can be improved, thereby improving the structural strength and bending and torsional stiffness of the vehicle door, and further enhancing the structural stability of the vehicle door.

[0013] In some examples of the present invention, the radius of the first transition arc is R1, and the R1 satisfies the relationship: 7mm ≤ R1 ≤ 12mm; and / or the radius of the second transition arc is R2, and the R2 satisfies the relationship: 5mm ≤ R2 ≤ 10mm.

[0029] The embodiments of the present utility model will be described in detail below. The embodiments described with reference to the drawings are exemplary.
[0030] Below with reference to Figures 1-4 Describe the nut plate 100 according to an embodiment of the present utility model. On the one hand, it can increase the avoidance area for avoiding adjacent structures through its own short side 2, and on the other hand, it can also increase the force-bearing contact area with adjacent structures through its own long side 3.
[0031] Combined with Figures 1-4 As shown, for the nut plate 100 according to the first aspect embodiment of the present utility model, the nut plate 100 is a polygonal plate, and the nut plate 100 includes two connecting edges 1 arranged at intervals in the first direction and a short side 2 and a long side 3 arranged at intervals in the second direction.
[0032] Specifically, the connecting edge 1 is connected between the short side 2 and the long side 3. The length of the long side 3 is greater than the length of the short side 2. The long side 3 can increase the force-bearing contact area between the nut plate 100 and the matching structure, thereby improving the connection strength; while the short side 2 can, on the basis of ensuring the connection between the nut plate 100 and the matching structure, increase the avoidance dimension of the nut plate 100 for avoiding the relevant structure shape, thereby reducing the risk of structural interference, and further improving the reliability and versatility when the nut plate 100 is matched with different car doors 200.
[0033] Specifically, a nut hole 101 is provided on one side of the nut plate 100 close to the long side 3. The two ends of the short side 2 are connected between the first ends of the two connecting edges 1, and the two ends of the long side 3 are connected between the second ends of the two connecting edges 1. The first direction is perpendicular to the second direction.
[0034] Further, the nut hole 101 is eccentrically disposed on the nut plate 100 on the side close to the long side 3 in the second direction. When the nut plate 100 is installed with a matching structure, the force distribution can be made closer to the long side 3, thereby increasing the connection force-bearing area, improving the force uniformity, enhancing the structural strength and the flexural and torsional stiffness of the door 200, and further enhancing the structural stability of the door 200.
[0035] Furthermore, the long side 3 is close to the hemming side 61 of the inner panel 6, so that the force-bearing area at the hinge position can be made as large as possible, and at the same time it is as close as possible to the hemming side 61. The uniform distribution of the force is realized through the entire circumferential structure of the hemming side 61, thereby improving the vertical strength and stiffness of the door 200 and enhancing the structural stability of the door 200.
[0036] Thus, by providing the nut plate 100, on the one hand, the avoidance area for avoiding adjacent structures can be increased through its short side 2, and on the other hand, the force-bearing contact area with adjacent structures can be increased through its long side 3, thereby improving its versatility when matching with doors 200 of different shapes.
[0037] According to some alternative embodiments of the present invention, in combination with Figure 3 and Figure 4 as shown, the nut plate 100 is a trapezoidal plate, and the short side 2 and the long side 3 are parallel to each other. Among them, the short side 2 and the long side 3 of the nut plate 100 are in a parallel relationship, which is convenient for processing and manufacturing, simplifies the manufacturing process, and can effectively avoid relevant structural shapes, thereby improving the scientific nature of its design.
[0038] Specifically, in combination with Figure 3 and Figure 4 as shown, the connecting edges 1 are of equal length, and the two connecting edges 1 are away from each other in the direction of extending from the first end to the second end.
[0039] It can be understood that since the short side 2 and the long side 3 are parallel to each other and the connecting edges 1 are of equal length, the nut plate 100 is constructed as an isosceles trapezoid, so that the specifications of the nut plate 100 are more regular and concise, thereby facilitating the simplification of the manufacturing process and improving the processing efficiency. Among them, the nut plate 100 is symmetrically disposed in the first direction, so that its own generalization effect can be improved.
[0040] Further, in combination with Figure 3 and Figure 4 as shown, the nut plate 100 further includes a first transition arc 4 and a second transition arc 5. The first transition arc 4 is connected between the short side 2 and the connecting edge 1, and the second transition arc 5 is connected between the long side 3 and the connecting edge 1.
[0041] That is to say, the four first transition arcs can play a role in evenly transitioning and connecting the short side 2 and the connecting side 1, avoiding the formation of a stress concentration area at the connection between the short side 2 and the connecting side 1. The five second transition arcs can play a role in evenly transitioning and connecting the long side 3 and the connecting side 1, avoiding the formation of a stress concentration area at the connection between the long side 3 and the connecting side 1. Thus, on the one hand, the machining continuity of the outer contour of the nut plate 100 can be improved, and on the other hand, the stress can be effectively dispersed, avoiding stress concentration at sharp edges or corners, thereby reducing the risk of fatigue and fracture of the nut plate 100.
[0042] Specifically, as shown in Figure 3 and Figure 4 , the radius of the first transition arc 4 is greater than the radius of the second transition arc 5. Such an arrangement can, on the premise of facilitating the long side 3 to be closer to the adjacent structural shape, also increase the connection stress-bearing area on one side of the long side 3, thereby improving the structural strength and stiffness of the vehicle door 200; it can also, on the basis of ensuring the connection between one side of the short side 2 and the matching structure, increase the avoidance dimension for avoiding local shapes, thereby improving the matching universality rate of the nut plate 100 with different-shaped vehicle doors 200.
[0043] In addition, the nut plate 100 can be rotated along the axis of the nut hole 101 to achieve further matching with the shape, avoiding non-universality due to different shapes.
[0044] Specifically, as shown in Figure 3 and Figure 4 , the radius of the first transition arc 4 is R1, and R1 satisfies the relationship: 7 mm ≤ R1 ≤ 12 mm; the radius of the second transition arc 5 is R2, and R2 satisfies the relationship: 5 mm ≤ R2 ≤ 10 mm.
[0045] It can be understood that since the radius of the first transition arc 4 is greater than the radius of the second transition arc 5, on the one hand, the stress-bearing contact area on one side of the long side 3 can be ensured, and on the other hand, the avoidance dimension of one side of the short side 2 for the matching structure can be effectively increased, thereby improving its layout rationality and universality. For example, the radius R1 of the first transition arc 4 can be 7 mm, 8 mm, 10 mm or 12 mm, and is not limited thereto; the radius R2 of the second transition arc 5 can be 5 mm, 6 mm, 8 mm or 10 mm, and is not limited thereto.
[0046] According to some alternative embodiments of the present invention, as shown in Figure 4 , the nut plate 100 further includes a plurality of first welding parts 102 and a plurality of second welding parts 103. The plurality of first welding parts 102 are arranged at intervals along the first direction, and the plurality of second welding parts 103 are arranged at intervals along the first direction. In the second direction, the plurality of first welding parts 102 are located on the side adjacent to the short side 2 of the plurality of second welding parts 103.
[0047] Among them, multiple first welding parts 102 and multiple second welding parts 103 can connect the nut plate 100 and the matching structure into a whole through the welding process, thereby enhancing the connection reliability between the nut plate 100 and the related structure.
[0048] Specifically, in combination with Figure 4 As shown, the center of the nut hole 101 is located at the midpoint of the straight line connected by the centers of the multiple second welding parts 103. Such an arrangement can make the distance between the center of the nut hole 101 and the centers of the second welding parts 103 on its adjacent two sides equal, and the centers of the three are on the same straight line. This can maximize the uniformity of the force distribution, and further improve the stability and reliability when the nut plate 100 is connected to the matching structure.
[0049] Furthermore, both the first welding part 102 and the second welding part 103 are two. The distance between the two first welding parts 102 is less than the distance between the two second welding parts 103. The shape formed by connecting the centers of the first welding part 102 and the second welding part 103 in sequence is an isosceles trapezoid.
[0050] Among them, the first welding part 102 and the second welding part 103 are conformally matched with the outer contour of the nut plate 100. The two first welding parts 102 are close to the short side 2, and the two second welding parts 103 are close to the long side 3. The distance between the two first welding parts 102 is less than the distance between the two second welding parts 103. In this way, the first welding part 102 and the second welding part 103 can be closer to the corners of the nut plate 100, thereby improving the connection strength at the force-weak area (that is, the corners between the sides) on the nut plate 100, and further improving the connection reliability.
[0051] In combination with Figure 1 and Figure 2 As shown, the vehicle door 200 according to the second aspect embodiment of the present invention includes an inner panel 6, a hinge reinforcement plate 7, the above-mentioned nut plate 100 and a nut 8. The hinge reinforcement plate 7 is connected to the outside of the inner panel 6. The nut plate 100 is connected to the hinge reinforcement plate 7. The long side 3 is close to the hemming side 61 of the inner panel 6. The nut 8 is installed on the nut plate 100, and the nut 8 corresponds to the nut hole 101.
[0052] Specifically, in the direction from the inside to the outside, the inner panel 6, the hinge reinforcement plate 7, the nut plate 100 and the hinge are connected into a whole in sequence. In this way, their weights and spatial modes can be increased mutually, thereby improving their respective structural strengths and flexural and torsional rigidities.
[0053] Among them, the long side 3 of the nut plate 100 is close to the edge-wrapped side 61 of the inner plate 6. In this way, the force distribution between the nut 8 and the nut plate 100 can be made close to the edge-wrapped side 61, so that the force-bearing area at the hinge connection is as large as possible and as close to the edge-wrapped side 61 as possible. The uniformity of the force distribution is improved through the whole-circle structure of the edge-wrapped side 61, the strength and stiffness of the vehicle door 200 itself are improved, and further the structural stability of the vehicle door 200 is enhanced.
[0054] According to some alternative embodiments of the present utility model, in combination with Figure 1 and Figure 2 As shown, the hinge reinforcement plate 7 is provided with a connection hole 71. The connection hole 71 includes a head 711 and a tail 712. The head 711 is connected above the tail 712 and the tail 712 extends downward, and the head 711 corresponds to the nut hole 101.
[0055] Among them, the nut 8 can pass through the nut hole 101 and the connection hole 71 to connect the nut plate 100 and the hinge reinforcement plate 7 into a stable whole. In addition, the head 711 of the connection hole 71 can be used to pass through the nut 8, and the tail 712 of the connection hole 71 can increase the opening size of the head 711, so as to facilitate drainage and heat dissipation. In addition, the tail 712 of the connection hole 71 extends downward, so that the liquid can be smoothly discharged under the action of gravity.
[0056] For example, when the surface of the hinge reinforcement plate 7 is subjected to a painting process, the tail 712 of the connection hole 71 can ensure that the electrophoresis liquid can be completely discharged during the electrophoresis process of the hinge reinforcement plate 7, so as to ensure that there will be no quality defect problems in the subsequent painting and baking processes.
[0057] Specifically, in combination with Figure 1 As shown, the vehicle door 200 further includes a window frame reinforcement plate 201, which forms the upper assembly structure of the vehicle door 200 with the inner plate 6, provides the installation positions of other accessories on the upper part of the vehicle door 200 and the glass sliding support structure. The hinge reinforcement plate 7 of the vehicle door 200 includes an upper hinge reinforcement plate and a lower hinge reinforcement plate. The upper hinge reinforcement plate is arranged at a position on the vehicle door 200 close to the water cut part. This structure is welded to the nut plate 100 to form a reinforcement structure at the hinge connection position and is also the main force-bearing structure of the entire vehicle door 200; the lower hinge reinforcement plate is at a position on the vehicle door 200 close to the lower part. This structure is welded to the nut plate 100 to form a reinforcement structure at the hinge connection position and is also the main force-bearing structure of the entire vehicle door 200. The inner plate 6 is the basic structure of the vehicle door 200 assembly structure, and all other parts will be combined with this structure in a welding form or a screwing form, and finally a complete welded assembly structure of the vehicle door 200 is formed, providing an installation basis for other accessories.
[0058] A vehicle according to a third aspect embodiment of the present utility model includes the vehicle door 200 of the above embodiment. Thus, the vehicle having the vehicle door 200 can improve the generalization design effect of the local position of the vehicle door 200, thereby shortening the design cycle of the whole vehicle and further enhancing the market competitiveness.
