Description

Technical Field

[0001] This invention belongs to the field of automotive engine hood installation, specifically relating to an engine hood hinge installation structure, installation method, and vehicle. Background Technology

[0002] As an important part of the vehicle, the engine hood is connected to the body through hinges and latches. The engine hood hinges are usually directly mounted on the shotgun (upper longitudinal beam) body.

[0003] Chinese patent CN215752664U discloses a new energy vehicle engine hood mounting bracket, comprising: an engine hood mounting bracket body; a notch provided on the first side of the engine hood mounting bracket body, the notch being connected to a water channel assembly; flanges provided on the second and third sides of the engine hood mounting bracket body, the flanges being connected to a wheel arch reinforcement beam assembly; and a fourth side of the engine hood mounting bracket body being connected to a side panel assembly, which not only satisfies the functional requirements for installing engine hood hinges but also integrates other related mounting points.

[0004] Chinese patent application CN114889702A discloses a novel front hood hinge reinforcement plate structure, including bolts, an outer front hood plate, a front hood hinge reinforcement plate, an inner front hood plate, and a front hood hinge. Bolts are protruding onto the front hood hinge. The front hood hinge and the inner front hood plate are attached and welded together. The front hood hinge reinforcement plate has a Z-direction flange, which is used to wrap the front hood hinge reinforcement plate and the outer front hood plate to form a front hood sheet metal assembly. This invention has a simple structure, good formability, structural stability, and high rigidity, meeting design requirements.

[0005] Chinese Patent CN208827953U discloses a multifunctional hinge reinforcement plate assembly and an automobile equipped with this structure. The multifunctional hinge reinforcement plate assembly is disposed between the outer and inner panels of the automobile hood, and includes a hinge reinforcement plate and a projection-welded nut. The projection-welded nut is welded to the hinge reinforcement plate. The hinge reinforcement plate is generally elongated, and along its length, upward-folding support claws are provided on both sides. These support claws support the outer panel of the hood along the hinge reinforcement plate, while the hinge reinforcement plate is welded to the inner panel of the hood. This multifunctional hinge reinforcement plate assembly provides mounting points for the hinges, ensuring the strength of these points, while also supporting the outer panel of the hood through vibration-damping adhesive application via an adhesive groove, improving the overall rigidity of the hood. This achieves a "two-in-one" functionality, reducing the number of parts, contributing to vehicle lightweighting, lower fuel consumption, and improving the overall vehicle design.

[0006] However, the above-mentioned shortcomings include insufficient rigidity and strength of the engine hood hinge mounting point; and if the projection weld nut falls off or is welded off-center during use, it is difficult to repair.

[0007] In view of this, the present invention is hereby proposed. Summary of the Invention

[0008] In the existing technology, because the projection weld nut is hidden in the sheet metal section of the upper longitudinal beam, the installation direction is basically along the Z direction of the whole vehicle, and due to the space limitation inside, it is difficult to add a reinforcing plate, resulting in insufficient rigidity and strength of the engine hood hinge mounting point on the side of the vehicle body.

[0009] To address the technical problems existing in the prior art, this invention provides an engine hood hinge mounting structure, mounting method, and vehicle. This invention is not only simple in structure and easy to operate, but also has high structural strength and rigidity. Furthermore, the structure of this invention is easy to repair and maintain in the event of the projection weld nut falling off or being welded off-center.

[0010] This invention includes the following technical solutions:

[0011] The first aspect of the present invention provides an engine hood hinge mounting structure, comprising: an L-shaped bracket and a Z-shaped bracket, wherein the L-shaped bracket includes a first connecting part and a second connecting part, the first connecting part is used to connect to one side of an upper longitudinal beam, one side of the second connecting part is connected to the Z-shaped bracket, and a protruding bolt is provided on the opposite side of the second connecting part connected to the Z-shaped bracket, the protruding bolt being along the Y direction of the entire vehicle;

[0012] The Z-shaped bracket includes a first part, a second part, and a third part. The second part is disposed between the first part and the second part. The first part is connected to the second connecting part. The third part is used to connect to the other side of the upper longitudinal beam.

[0013] Furthermore, the angle between the first part and the second part is 120°; and / or the angle between the second part and the third part is 120°.

[0014] Furthermore, the included angle between the first connecting part and the second connecting part of the L-shaped bracket is set to 90°, so that the L-shaped bracket and the Z-shaped bracket form a 90° bracket assembly after being connected.

[0015] Furthermore, the L-shaped bracket is provided with reinforcing ribs; and / or the L-shaped bracket is provided with a first weight-reducing hole; and / or the L-shaped bracket is provided with a first flange structure.

[0016] Furthermore, the reinforcing rib is located at the junction of the first connecting portion and the second connecting portion.

[0017] Furthermore, the Z-shaped bracket is provided with hinge mounting holes corresponding to the convex bolts.

[0018] Furthermore, the Z-shaped bracket is provided with a second weight-reducing hole; and / or the Z-shaped bracket is provided with a second flange structure.

[0019] A second aspect of the present invention provides an installation method for an engine hood hinge mounting structure, comprising the mounting structure described above, the installation method comprising:

[0020] A bracket is obtained by connecting an L-shaped bracket and a Z-shaped bracket;

[0021] Connect the bracket to the upper longitudinal beam;

[0022] Connect the convex nut to the L-shaped bracket.

[0023] Furthermore, the L-shaped bracket and the Z-shaped bracket are connected by welding; and / or the bracket is connected to the upper longitudinal beam by welding; and / or the protruding nut is connected to the L-shaped bracket by welding.

[0024] A third aspect of the present invention provides a vehicle including an engine hood, an upper longitudinal beam, a hinge, and the aforementioned mounting structure, wherein the mounting structure is connected to the hinge via a bolt, and the hinge is connected to the engine hood.

[0025] By adopting the above technical solution, the present invention has the following advantages:

[0026] 1. This invention is not only simple in structure and easy to operate, but also has high structural strength and rigidity. In addition, the structure of this invention is easy to repair and maintain in the event of the projection weld nut falling off or being welded off-center.

[0027] 2. The engine hood hinge mounting point (convex nut) in the invention has changed its previous arrangement. The original mounting direction has been changed from the "Z" direction of the whole vehicle to an L-shaped bracket. 3. After the Z-shaped bracket is welded together, it is welded to the two planes of the shotgun. The mounting direction has changed to the "Y" direction of the whole vehicle. The convex nut has also been changed from being located in the shotgun cavity to being located on the side of the L-shaped bracket. This structure not only enhances the rigidity and strength of the engine hood hinge mounting point, but also effectively improves and optimizes the ease of operation and maintainability. The system has high stability and is easy to implement. Attached Figure Description

[0039] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0040] The first aspect of this embodiment provides an engine hood hinge mounting structure, such as... Figure 1 , Figure 2 As shown, it includes an L-shaped bracket 10 and a Z-shaped bracket 20. The L-shaped bracket 10 includes a first connecting part 101 and a second connecting part 102. The first connecting part 101 is used to connect to one side of the upper longitudinal beam 40, and one side of the second connecting part 102 is connected to the Z-shaped bracket 20. A protruding bolt 30 is provided on the opposite side of the second connecting part 102 connected to the Z-shaped bracket 20. The protruding bolt 30 is welded along the Y direction of the whole vehicle, which is beneficial to the assembly and hinge structure design.

[0041] The Z-shaped bracket 20 includes a first part 201, a second part 202 and a third part 203. The second part 202 is disposed between the first part 201 and the second part 202. The first part 201 is connected to the second connecting part 102. The third part 203 is used to connect to the other side of the upper longitudinal beam 40.

[0042] It should be noted that the Y direction is the defined Y direction, which can also be called the X direction, but the X direction or Y direction is a direction that is different from the Z direction.

[0043] The way the L-shaped bracket 10 and the Z-shaped bracket work together can improve the strength and rigidity of the installation structure, and can also work with the convex bolt 30; the position of the convex bolt 30 makes it easier to connect with the hinge 50.

[0044] In some embodiments, the angle between the first portion 201 and the second portion 202 is 120°; and / or the angle between the second portion 202 and the third portion 203 is 120°. This ensures optimal rigidity and strength while maintaining the desired molding process.

[0045] In some embodiments, such as Figure 1 , Figure 2 As shown, the included angle between the first connecting part 101 and the second connecting part 102 of the L-shaped bracket 10 is set to 90°. After the L-shaped bracket 10 is connected to the Z-shaped bracket 20, a 90° bracket assembly is formed. This has the advantages of improving structural rigidity and strength, and is also convenient for welding and maintenance.

[0046] In some embodiments, the upper longitudinal beam 40 is designed to support the connection between the L-shaped bracket 10 and the Z-shaped bracket 20; the upper longitudinal beam 40 has a first surface for connecting to the L-shaped bracket 10 and a second surface for connecting to the Z-shaped bracket 20, the first surface and the second surface are fixedly connected, and the first surface and the second surface are preferably at 90°. This facilitates the welding of the protruding bolts 30 along the Y-direction of the vehicle.

[0047] In some embodiments, such as Figure 3 As shown, the L-shaped bracket 10 is provided with reinforcing ribs 11; and / or the L-shaped bracket 10 is provided with first weight-reducing holes 12; and / or the L-shaped bracket 10 is provided with first flange structure 13.

[0048] The first weight-reducing hole 12 can reduce the weight of the mounting structure, thereby reducing the overall vehicle weight; it also has the advantage of reducing costs.

[0049] The design of the first flange structure 13 can improve the structural rigidity and strength performance of the bracket itself.

[0050] The reinforcing rib 11 has the advantage of improving the strength and rigidity of the installation structure.

[0051] In some embodiments, such as Figure 3 As shown, the reinforcing rib 11 is located at the junction of the first connecting portion 101 and the second connecting portion 102. Based on this structure, the L-shaped bracket 10 has higher strength and rigidity.

[0052] In some embodiments, such as Figure 3As shown, the L-shaped bracket 10 is provided with a first boss structure 14. The first boss structure 14 is connected to the upper longitudinal beam 40 by spot welding after planar overlap.

[0053] In some embodiments, such as Figure 4 As shown, the Z-shaped bracket 20 is provided with hinge mounting holes 21 corresponding to the protruding bolts 30. This structure facilitates the connection of the hinge 50 with the mounting structure of the present invention, reducing installation labor intensity and improving installation convenience.

[0054] In some embodiments, such as Figure 4 As shown, the Z-shaped bracket 20 is provided with a second weight-reducing hole 22; and / or the Z-shaped bracket 20 is provided with a second flange structure 23.

[0055] The second weight reduction hole 22 can reduce the weight of the mounting structure, thereby reducing the overall vehicle weight; it also has the advantage of reducing costs.

[0056] The design of the second flange structure 23 can improve the structural rigidity and strength performance of the bracket itself.

[0057] In some embodiments, such as Figure 4 As shown, the Z-shaped bracket 20 is provided with a second boss structure 24.

[0058] The second aspect of this embodiment provides an installation method for an engine hood hinge 50 mounting structure, including the mounting structure described above, and the installation method includes:

[0059] Connect the L-shaped bracket 10 and the Z-shaped bracket 20 to obtain a bracket;

[0060] Connect the bracket to the upper longitudinal beam 40;

[0061] Connect the convex nut to the L-shaped bracket 10.

[0062] In the installation method of the present invention, the L-shaped bracket 10 and the Z-shaped bracket 20 are first connected. The connected bracket is easier to position when connected to the upper longitudinal beam 40, which has the advantages of improving assembly efficiency and assembly effect.

[0063] In some embodiments, the L-shaped bracket 10 and the Z-shaped bracket 20 are connected by welding; and / or the bracket is connected to the upper longitudinal beam 40 by welding; and / or the protruding nut is connected to the L-shaped bracket 10 by welding. Welding is a simple method of connection and facilitates production and assembly.

[0064] A third aspect of the present invention provides a vehicle, such as Figure 5As shown, the device includes an engine hood (not shown), an upper longitudinal beam 40, a hinge 50, and the aforementioned mounting structure. The mounting structure is connected to the hinge 50 via a bolt 30, and the hinge 50 is connected to the engine hood.

[0065] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
