Description

Technical Field

[0002] The car door is an important part of the whole vehicle, playing an important role in decoration, sealing, and anti-collision. The car door is generally hinged to the body pillar (such as the A-pillar) through a hinge. In existing models, taking the area where the A-pillar is located as an example, the A-pillar is mainly enclosed by the A-pillar reinforcement plate and the A-pillar inner plate to form a hollow structure, and the hinge mounting plate is arranged in the inner cavity of the A-pillar, and is fitted and connected to the A-pillar reinforcement plate. The hinge is installed on the stacked hinge mounting plate and the A-pillar reinforcement plate through fasteners. Since the hinge is the main load-bearing point of the car door, the above-mentioned adaptation method of the A-pillar and the hinge mounting plate is likely to cause deformation of the hinge mounting area, causing the car door to sag, causing interference between the car door and the body frame, abnormal noise, and long-term durable use. It will cause problems such as cracking of welding points, deformation of sheet metal, and paint grinding, which will affect customer use and cause complaints. Utility Model Content

[0031] Please also read Figures 1 to 3 Now, the vehicle door hinge installation structure assembly provided by the utility model is described. The vehicle door hinge installation structure assembly comprises a column body 1 and a hinge installation bracket 2; the column body 1 has a plurality of main body cavities 110 distributed along the front-back direction inside, the main body cavities 110 are closed cavities, the outer side surface of the column body 1 forms a hinge installation area, the hinge installation area corresponds to one of the main body cavities 110, and the main body cavity 110 corresponding to the hinge installation area is a hinge installation cavity 111; the hinge installation bracket 2 is arranged in the hinge installation cavity 111, and the outer side surface and at least one other side surface of the hinge installation bracket 2 are respectively connected to the column body 1 in a close fit.

[0032] In this embodiment, a solution in which the hinge 10 is connected to the door inner panel 9 is shown.

[0033] In this embodiment, the column body 1 can be formed by extrusion molding. The column body 1 has a high degree of integration, fewer joints, better structural strength, and a simpler manufacturing method, lower manufacturing cost, and greatly reduced number of parts, avoiding cumbersome later assembly steps and manufacturing and assembly errors. Based on this, combined with the high structural strength of the column body 1 itself, in order to facilitate extrusion molding, the column body 1 is made of aluminum alloy.

[0034] In this embodiment, the plurality of main body cavities 110 may be distributed along a straight path such as the front-to-back direction, the inside-out direction, or along a tortuous path such as an L-shaped path, and the structure in the pillar body 1 for dividing the space and forming the plurality of main body cavities 110 is a main body partition plate 120. The number of main body partition plates 120 may be one, two, or even more. If there are a plurality of main body partition plates 120, the plurality of main body partition plates 120 are distributed at intervals along the front-to-back direction. The number of main body partition plates 120 to be provided depends on the vehicle model and the indicators to be strengthened. This embodiment exemplarily shows an example of providing two main body partition plates 120 and separating three main body cavities 110.

[0035] In this embodiment, the column body 1 extends as a whole in the up-down direction, and the hinge mounting bracket 2 can be arranged one-to-one corresponding to the hinge 10, that is, multiple hinge mounting brackets 2 are arranged at intervals in the up-down direction in the column body 1; or, the hinge mounting bracket 2 is a strip-shaped component extending as a whole up-down similar to the column body 1, and a hinge mounting bracket 2 is arranged in the column body 1, and the hinge mounting bracket 2 corresponds to multiple hinges 10 at the same time.

[0036] Compared with the prior art, the vehicle door hinge installation structure assembly provided in this embodiment has multiple closed main body cavities 110 arranged inside the column main body 1, and the solid structure between two adjacent main body cavities 110 supports and strengthens the outer shell of the column main body 1, thereby improving the bearing capacity of the column main body 1; at the same time, the design of multiple closed cavities also increases the force transmission path inside the column main body 1 (the force transmission path along the up and down direction), realizes the effective decomposition of the force, and further improves the bearing capacity of the column main body 1. In addition, the outer side surface and at least one other side surface of the hinge installation bracket 2 are respectively connected to the column main body 1 in a fitting manner, and there are at least two joint surfaces between the two, so that the hinge installation bracket 2 forms an effective support inside the column main body 1, ensuring the support requirements for the installation of the hinge 10, and can also effectively transmit force through the hinge installation bracket 2, and further enhance the structural strength of the column main body 1 through the hinge installation bracket 2.

[0037] In this embodiment, the pillar body 1 is reinforced to improve its structural strength, and a hinge mounting bracket 2 with relatively high structural strength is used in combination, so that the pillar body 1 and the hinge mounting bracket 2 can provide more effective support after being assembled with the hinge 10, thereby effectively improving the problem of pillar deformation caused by the gravity of the door and preventing the door from sagging.

[0038] In some embodiments, see Figure 2 and Figure 3 , multiple main body cavities 110 are distributed along the front-to-back direction, and correspondingly, each main body partition plate 120 extends along the inside-outside direction; the interior of the hinge mounting bracket 2 has multiple bracket cavities 210 distributed along the front-to-back direction, and the bracket cavity 210 is a closed cavity. In this embodiment, the multiple main body cavities 110 distributed front-to-back enhance the bearing capacity of the column body 1 in the inside-outside direction, and improve the side collision safety of the side area; and the entity structure between two adjacent bracket cavities 210 supports and strengthens the outer shell of the hinge mounting bracket 2, and improves the bearing performance of the hinge mounting bracket 2 in the inside-outside direction; at the same time, the design of multiple closed cavities also increases the force transmission path inside the hinge mounting bracket 2 (the force transmission path along the up and down direction), realizes the effective decomposition of the force, and further improves the bearing performance of the hinge mounting bracket 2. In general, by strengthening the design of the pillar body 1 and improving its structural strength, and combining it with the hinge mounting bracket 2 with high structural strength, it is beneficial to improve the overall torsion and bending resistance of the vehicle body. By reasonably setting the front and rear widths of the pillar body 1, the force-bearing area during a collision is increased, the deformation of the vehicle body during a frontal collision and a side collision is reduced, and the safety of the vehicle and the occupants is protected.

[0039] In this embodiment, the hinge mounting bracket 2 can be formed by extrusion molding. The hinge mounting bracket 2 has a high degree of integration, fewer joints, better structural strength, and a simpler manufacturing method, lower manufacturing cost, and greatly reduced number of parts, avoiding cumbersome later assembly steps and manufacturing and assembly errors. Based on this, combined with the fact that the hinge mounting bracket 2 itself has a high structural strength, in order to facilitate extrusion molding, the hinge mounting bracket 2 is made of aluminum alloy.

[0040] In some specific embodiments, see Figure 2 and Figure 3 In order to fit the side panel and the door, the cross section of the pillar body 1 is rectangular or square as a whole, and the main body cavity 110 is also roughly rectangular or square. Correspondingly, in order to fit the shape of the main body cavity 110, the cross section of the hinge mounting bracket 2 is rectangular or square as a whole, which can be placed in the hinge mounting cavity 111 and fit and connect with at least two side surfaces of the hinge mounting cavity 111.

[0041] Based on the above embodiments, see Figure 2and Figure 3 The rear side and outer side of the hinge mounting bracket 2 are respectively connected to the pillar body 1, the front side of the hinge mounting bracket 2 is spaced apart from the pillar body 1, and the inner side of the hinge mounting bracket 2 is spaced apart from the pillar body 1. The force generated by the hinge 10 can be transmitted to the rear side through the outer side of the hinge mounting bracket 2, and finally transmitted to the pillar body 1, which can not only realize the effective transmission of the force, but also provide effective strengthening support for the installation of the hinge 10; in addition, the spacing design of the front and inner sides of the hinge mounting bracket 2 also plays a role in frequency avoidance, avoiding the vibration transmitted to the hinge mounting bracket 2 during driving to form a resonance effect.

[0042] In some embodiments, see Figure 2 and Figure 3 In order to realize the connection between the front side of the hinge mounting bracket 2 and the column body 1, the column body 1 has a plurality of bracket mounting points 3 distributed along the front-to-back direction, so as to improve the reliability of the connection through multi-point connection; based on this, the bracket mounting points 3 correspond to the bracket cavities 210 one by one, and the forces acting on each bracket mounting point 3 are respectively transmitted to different bracket cavities 210 of the hinge mounting bracket 2, which can better decompose stress and avoid stress concentration.

[0043] Similarly, the rear side wall of the hinge mounting cavity 111 is also provided with a plurality of bracket mounting points 3 to improve the reliability of the connection through a multi-point connection. The plurality of bracket mounting points 3 on the rear side wall of the hinge mounting cavity 111 can be distributed along the inner and outer directions, and the specific distribution method is related to the size of the hinge mounting bracket 2, which is not limited here.

[0044] In some embodiments, see Figure 2 and Figure 3 , the front-to-back widths of two adjacent bracket cavities 210 are different, that is, the cross-sectional shapes of two adjacent bracket cavities 210 are different, and the structure of the hinge mounting bracket 2 itself is asymmetric. This asymmetric performance further enhances the frequency avoidance effect, avoids resonance, and improves NVH performance. In specific implementation, the structure used to separate the space and form multiple bracket cavities 210 in the hinge mounting bracket 2 is a bracket partition plate 220, and the bracket partition plate 220 extends in the inward and outward directions. When a bracket partition plate 220 is set, the bracket partition plate 220 divides the internal space of the hinge mounting bracket 2 into two bracket cavities 210, and the bracket partition plate 220 roughly corresponds to the centerline position of the hinge mounting space, so as to be in the middle of the installation area corresponding to the hinge 10 as much as possible. This embodiment exemplarily shows that the front-to-back width of the bracket cavity 210 located on the front side is smaller than the front-to-back width of the bracket cavity 210 located on the rear side.

[0045] In some embodiments, see Figure 2 and Figure 3In order to adapt to the installation of the car door, the hinge installation cavity 111 is located at the rear of the pillar body 1. Based on this, an auxiliary partition plate 140 is provided in the main cavity 110 located at the front of the pillar body 1, and the auxiliary partition plate 140 divides the corresponding main cavity 110 into a plurality of partition cavities 130 distributed along the inner and outer directions. In fact, multiple groups of cavities distributed along different directions are formed inside the pillar body 1, which has high structural strength in the front-to-back direction and the inner-to-outer direction, and also has better bending and torsion resistance; and because the front-to-back width and the inner-to-outer width of the pillar body 1 are both large, the force-bearing area of ​​side collision and head-on collision can be increased, and the collision deformation can be reduced.

[0046] Based on the above embodiments, see Figure 2 and Figure 3 The inner and outer widths of two adjacent separation cavities 130 are different, which can further improve the frequency avoidance effect and the bending and torsion resistance of the column body 1. This embodiment exemplarily shows that the inner and outer widths of the separation cavity 130 located on the inner side are greater than the inner and outer widths of the separation cavity 130 located on the outer side.

[0047] In some embodiments, see Figure 2 and Figure 3 The door hinge mounting structure assembly also includes a mounting pad 4, the inner side of which is fitted and connected to the outer side of the pillar body 1, and a hinge mounting point 5 is provided on the outer side of the mounting pad 4. In this embodiment, the mounting pad 4 is thickened and reinforced in the mounting area corresponding to the hinge 10, which ensures that the area will not crack easily after the hinge is installed, and can also adapt to the connection with the hinge 10. In specific implementation, the mounting pad 4 is fitted and welded to the pillar body 1.

[0048] In some specific embodiments of the installation pad 4, see Figure 2 and Figure 3 The inner side of the mounting pad 4 is provided with connecting bosses 410, which can increase the connection contact area between the inner side of the mounting pad 4 and the column body 1, thereby enhancing the reliability of the connection; on the basis of effectively increasing the connection area between it and the column body 1, the outer side of the mounting pad 4 can also be made to adapt to the shape of the hinge 10, while avoiding occupying too large an area to affect the arrangement of other components on the column body 1, so that the outer end surface area of ​​the mounting pad 4 is not less than the area of ​​the hinge installation side.

[0049] In some embodiments, the outer side of the mounting pad 4 is provided with a plurality of hinge mounting points 5 distributed along the front-to-back direction, and each hinge mounting point 5 corresponds to a different bracket cavity 210. The specific corresponding manner is exemplified as follows: 1) If the number of hinge mounting points 5 and bracket cavities 210 is the same, then the hinge mounting points 5 correspond to the bracket cavities 210 one by one, such as Figure 2 and Figure 3As shown; 2) the number of hinge mounting points 5 is greater than the number of bracket cavities 210, then each bracket cavity 210 corresponds to at least one hinge mounting point 5; 3) the number of hinge mounting points 5 is less than the number of bracket cavities 210, then one hinge mounting point 5 corresponds to one bracket cavity 210.

[0050] In some specific embodiments of the hinge mounting point 5, the hinge mounting point 5 is a hinge mounting hole, and the hinge is locked with the mounting pad 4 by a hinge fastener. The hinge fastener may be implemented in a manner including, but not limited to, a bolt, a straight-insert buckle, a rivet, etc., and the hinge mounting hole may be correspondingly configured as a screw hole, a clamping hole, a rivet hole, etc.

[0051] In some embodiments, see Figure 1 and Figure 2 The door hinge installation structure assembly also includes a pillar reinforcement plate 6 and a side panel 7; the pillar reinforcement plate 6 is fitted and connected to the inner side of the pillar body 1 and protrudes backward from the pillar body 1; the side panel 7 is fitted and connected to the outer side of the pillar body 1 and protrudes backward from the pillar body 1 across the installation pad 4; the rear part of the side panel 7 is fitted and connected to the rear part of the pillar reinforcement plate 6, and the side panel 7, the pillar reinforcement plate 6 and the rear side of the pillar body 1 enclose a triangular reinforcement cavity 8. The reinforcement cavity 8 is a closed cavity, and the rear part of the pillar body 1 is further strengthened through the triangular cavity structure, thereby improving the overall structural strength of the door hinge installation structure assembly, and at the same time improving the multi-directional load-bearing performance, thereby improving the bending and torsion resistance.

[0052] Based on the above embodiments, see Figure 1 and Figure 2 The main body of the side outer panel 7 and the mounting pad 4 are arranged with an inner and outer spacing, and a reinforcing rib 710 is recessed inwardly on the side outer panel 7. The inner side surface of the reinforcing rib 710 is in contact with the outer side surface of the mounting pad 4 (the two may only be in contact, or may be in contact with each other by welding or the like). The inner wall of the reinforcing rib 710 is padded between the hinge 10 and the mounting pad 4. The side outer panel 7 and the pillar main body 1 are further fixed by synchronously installing the hinge 10 and the mounting pad 4, thereby enhancing the integrity of the side outer panel 7 and the pillar main body 1, promoting the overall structural strength of the side door hinge mounting structure assembly, and helping to improve the problem of noise excitation transmitted to the vehicle interior through the pillar main body 1 at that location.

[0053] On the basis that the hinge mounting point 5 is a hinge mounting hole, see Figure 1 and Figure 2, the hinge mounting hole passes through the mounting pad 4 inside and outside, the bracket mounting point 3 is the bracket mounting hole, the bracket mounting hole corresponds to the hinge mounting hole, and the hinge mounting bracket 2 is locked with the column body 1 by the bracket fastener that passes through the hinge mounting bracket 2, the bracket mounting hole and the hinge mounting hole. The implementation methods of the bracket fastener include but are not limited to bolts, straight-insert buckles, rivets, etc., which are not listed here one by one. In this embodiment, the hinge mounting hole is functionally integrated, the outer end of the hinge mounting hole is adapted to the hinge fastener, and the inner end is adapted to the bracket fastener, which satisfies the assembly of the hinge 10 and the hinge mounting bracket 2, while reducing the number of holes opened on the mounting pad 4, so that the size of the mounting pad 4 in the direction perpendicular to the inner and outer directions can be smaller, and the compact design of the mounting pad 4 can be achieved.

[0054] On the basis of the above-mentioned embodiment, the ratio of the thickness of the mounting pad 4 to the thickness of the side wall of the column body 1 is not less than 10:1. On the basis of satisfying the requirement of enhancing the structural strength of the mounting area corresponding to the hinge 10 by means of the mounting pad 4, the space of the mounting pad 4 can also be fully utilized to make the length of the hinge mounting hole long enough, while satisfying the requirement of being compatible with the hinge fasteners and the bracket fasteners.

[0055] Based on the same inventive concept, an embodiment of the present application also provides a vehicle, comprising the above-mentioned door hinge mounting structure assembly.

[0056] Compared with the prior art, the vehicle provided in this embodiment has an effectively improved door sagging problem by adopting the above-mentioned door hinge mounting structure assembly, and can avoid problems such as weld cracking, sheet metal deformation, and paint grinding after long-term durable use, thereby effectively improving the quality of the entire vehicle.

[0057] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
