This installation method limits the width of the hood. Utility Model Content

[0031] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0032] like Figure 1-Figure 6 As shown, the embodiment of the present application provides an upper longitudinal beam structure, the outer side wall of the upper longitudinal beam structure has an installation area, the installation area is used to install the connecting rod hinge 500, and the installation area is processed with a reinforcement structure, that is, the reinforcement structure is formed by processing the installation area. Optionally, the reinforcement structure can be distributed only on the surface of the outer side wall of the upper longitudinal beam structure, or the reinforcement structure can also be distributed on the entire wall thickness of the upper longitudinal beam structure, and the direction of the wall thickness refers to the direction from the outer side wall to the inner side wall of the upper longitudinal beam structure.

[0033] The upper longitudinal beam structure in the present application can be applied to a vehicle, the front-to-rear direction (length direction) of the vehicle is defined as the X direction, the left-to-right direction (width direction) of the vehicle is defined as the Y direction, and the up-down direction (height direction) of the vehicle is positioned as the Z direction, and each direction of the upper longitudinal beam structure is the same as each direction of the vehicle. The side wall of the upper longitudinal beam structure refers to the XZ plane of the upper longitudinal beam structure after the upper longitudinal beam structure is applied to the vehicle, and the side wall of the upper longitudinal beam structure includes an inner side wall and an outer side wall facing each other, the outer side wall faces the outside of the vehicle, and the inner side wall faces the inside of the vehicle.

[0034] When the upper longitudinal member structure is used in a vehicle, the hood is rotatably mounted to the upper longitudinal member structure via the link hinge 500 .

[0035] In a vehicle, upper longitudinal beam structures are usually used in pairs, and a connecting rod hinge 500 is installed on each upper longitudinal beam structure. The two ends of the hood are respectively connected to each connecting rod hinge 500. The larger the distance between the connecting rod hinges 500 on the two upper longitudinal beam structures, the larger the size of the hood in the Y direction (width direction) can be.

[0036] In the prior art, the connecting rod hinge 500 is installed on the XY plane of the upper longitudinal beam structure along the Z direction, while when the upper longitudinal beam structure in the present application is applied to a vehicle, the connecting rod hinge 500 is installed on the XZ plane of the upper longitudinal beam structure along the Y direction. When the vehicle body is fixed, compared with the installation method of the connecting rod hinge 500 in the prior art, the installation method of the connecting rod hinge 500 in the present application allows the connecting rod hinge 500 to expand outward from the vehicle, that is, to move outward from the vehicle, so that the distance between the connecting rod hinges 500 on the two upper longitudinal beam structures is increased, and a hood with a larger size in the Y direction can be installed. In other words, under limited vehicle body conditions, compared with the prior art, the installation method of the connecting rod hinge 500 in the present application can install a hood with a larger size in the Y direction.

[0037] In the embodiment of the present application, the outer side wall of the upper longitudinal beam structure has an installation area for installing the connecting rod hinge 500. After the upper longitudinal beam structure is applied to the vehicle, the distance between the outer side walls of the two upper longitudinal beam structures arranged in pairs is large, so that the distance between the connecting rod hinges 500 on the two upper longitudinal beam structures is large. Under the same vehicle body conditions, compared with the installation method of the connecting rod hinge 500 in the prior art, the present application can install a hood with a larger width, so that the width of the vehicle hood is larger, thereby satisfying the visual beauty and atmosphere. It can be seen that the upper longitudinal beam structure provided by the present application can solve the problem in the prior art that the installation method of the upper longitudinal beam structure and the connecting rod hinge leads to a smaller width of the vehicle hood.

[0038] However, when the outer wall of the upper longitudinal beam structure and the connecting rod hinge 500 are connected in cooperation, the connecting rod hinge 500 needs to be installed in the Y direction. The stiffness of the upper longitudinal beam structure in the XZ plane, that is, the stiffness in the Y direction is relatively low, which can easily cause the hood to shake left and right during vehicle driving, affecting driving safety and comfort. Long-term use will also cause irreversible damage to the vehicle itself.

[0039] To this end, in the embodiment of the present application, the installation area of ​​the upper longitudinal beam structure is processed with a reinforcement structure, and the local stiffness of the installation area is increased through the reinforcement structure to improve the stability of the connecting rod hinge 500 after installation, thereby improving the stability of the hood after the hood is installed through the connecting rod hinge 500.

[0040] In other embodiments, the rigidity of the installation area can be improved by increasing the connection between the upper longitudinal beam structure (such as the reinforcing plate 300 of the upper longitudinal beam structure) and the surrounding panels (the panels of the vehicle located around the upper longitudinal beam structure). However, this method will result in a larger size of the upper longitudinal beam structure, more welding points connecting the upper longitudinal beam structure and the surrounding panels, and the connection points between the upper longitudinal beam structure and the surrounding panels are far from the installation area, resulting in limited improvement in the rigidity of the installation area.

[0041] Compared with the above-mentioned method of improving stiffness, the stiffness of the installation area is improved by processing a reinforcing structure in the installation area of ​​the upper longitudinal beam structure, and the stiffness of the installation area in the XZ plane, that is, the stiffness in the Y direction, is improved. This method can further improve the stiffness performance of the installation area, and is convenient for controlling the size of the upper longitudinal beam structure, reducing welding points, and reducing costs.

[0042] There are many types of reinforcement structures. In an optional embodiment, the reinforcement structure may be a reinforcement rib.

[0043] In another optional embodiment, the reinforcement structure may be a concave-convex structure, which may include a connected mounting boss 100 and a first groove 200, and the mounting boss 100 is used to mount the connecting rod hinge 500. In this case, no additional material is needed, which can achieve the purpose of improving the rigidity of the mounting area and the rigidity of the XZ plane of the mounting area, and can also improve the material utilization rate and save costs.

[0044] While ensuring other properties of the mounting area, the Y-direction dimension of the mounting boss 100 can be increased as much as possible, thereby maximizing the rigidity of the mounting area.

[0045] In a further technical solution, the first groove 200 may be distributed around the mounting boss 100, and the mounting boss 100 may be formed by the first groove 200 being recessed in a direction away from the outer side wall. In this case, no convex bump is formed on the outer side wall of the upper longitudinal beam structure, and when the upper longitudinal beam structure is used in a vehicle, no convex bump is formed on the outer surface of the vehicle, thereby ensuring the aesthetic appearance of the vehicle.

[0046] In the embodiment of the present application, along the direction from the inner side wall to the outer side wall of the upper longitudinal beam structure, the upper longitudinal beam structure may include a stacked and connected reinforcing plate 300 and an outer plate 400, the reinforcing plate 300 may be provided with a connecting boss 330, and the outer plate 400 may be connected to the connecting boss 330 to achieve connection with the reinforcing plate 300. In this case, the connection between the reinforcing plate 300 and the outer plate 400 can be achieved, and the rigidity of the reinforcing plate 300 can be improved through the connecting boss 330, and the rigidity of the reinforcing plate 300 in the XZ plane can be improved, thereby improving the rigidity of the upper longitudinal beam structure in the XZ plane.

[0047] Optionally, the outer panel 400 may be connected to the connecting boss 330 by welding to achieve a fixed connection between the outer panel 400 and the reinforcing plate 300, and the welding connection method can ensure the connection strength between the outer panel 400 and the reinforcing plate 300, or the outer panel 400 and the connecting boss 330 may also be connected by bolts to achieve a fixed connection between the outer panel 400 and the reinforcing plate 300. Of course, in other embodiments, the reinforcing plate 300 and the outer panel 400 may also be connected by edge connection (for example, the edge of the reinforcing plate 300 is connected by welding to the edge of the outer panel 400) to achieve the connection between the two.

[0048] In a further technical solution, the reinforcing plate 300 may be provided with second grooves 340 , which are connected to the connecting bosses 330 and are staggeredly distributed. The connecting bosses 330 are formed by the second grooves 340 being recessed in a direction away from the outer side wall.

[0049] In this case, there is no need to generate a bulge on the reinforcing plate 300 protruding toward the outer panel 400 due to the addition of the connecting boss 330. Therefore, there is no need to form a corresponding bulge on the outer panel 400 at a position corresponding to the connecting boss 330, so that no bulge will be formed on the outer side wall of the upper longitudinal beam structure. When the upper longitudinal beam structure is used in a vehicle, no bulge will be formed on the outer surface of the vehicle, thereby ensuring the aesthetic appearance of the vehicle's external shape.

[0050] When the upper longitudinal beam structure includes a stacked and connected reinforcing plate 300 and outer plate 400, the mounting boss 100 may include a first boss 110 located on the reinforcing plate 300 and a second boss located on the outer plate 400. The first boss 110 and the second boss may be opposite and in contact with each other.

[0051] In order to further improve the Y-direction rigidity of the installation area, the first boss 110 may include a plurality of first sub-bosses 111, and the installation boss 100 may be provided with a plurality of installation holes 120, the installation holes 120 are used to cooperate with the installation of the connecting rod hinge 500, the installation holes 120 may penetrate the installation boss 100, and each first sub-boss 111 has a mounting hole 120. In this case, the size of each first sub-boss 111 provided with the mounting hole 120 can be reduced, and the rigidity of the area corresponding to the installation area of ​​the reinforcing plate 300 is further improved, thereby further improving the Y-direction rigidity of the area around the mounting hole 120 used to cooperate with the connecting rod hinge 500, and at the same time, the material distribution of the entire reinforcing plate 300 is made more reasonable, and the use and cost of materials are minimized.

[0052] Optionally, the number of the first sub-bosses 111 may be the same as the number of the mounting holes 120, and the first sub-bosses 111 and the mounting holes 120 may correspond one to one, for example, the number of the first sub-bosses 111 and the mounting holes 120 may be two, and each first sub-boss 111 has one mounting hole 120. Under the premise that the mounting boss 100 includes the mounting holes 120 and does not affect other properties of the mounting area, the dimensions of the mounting boss 100 in the X and Z directions are as small as possible to maximize the rigidity of the XZ plane of the mounting area.

[0053] In a further technical solution, a third groove 350 may be provided between two adjacent first sub-bosses 111, and the first sub-bosses 111 may be formed by the third groove 350 being recessed in a direction away from the outer side wall of the upper longitudinal beam structure. The reinforcing plate 300 may be provided with a fourth groove 360, and the fourth groove 360 ​​may be distributed around the first boss 110, and the first boss 110 may be formed by the fourth groove 360 ​​being recessed in a direction away from the outer side wall of the upper longitudinal beam structure. The outer plate 400 may be provided with a fifth groove, and the fifth groove may be distributed around the second boss, and the second boss may be formed by the fifth groove being recessed in a direction away from the outer side wall of the upper longitudinal beam structure. Optionally, the first groove 200, the fourth groove 360 ​​and the fifth groove may all be L-shaped, and the design of the fourth groove 360 ​​can not only construct the first boss 110, but also make the transmission of force more continuous.

[0054] In this case, no bulge protruding toward the outer panel 400 will be formed on the reinforcing plate 300, and no bulge protruding toward the outer side wall will be formed on the outer panel 400, so that no bulge will be formed on the outer side wall of the upper longitudinal beam structure. When the upper longitudinal beam structure is used in a vehicle, no bulge will be formed on the outer surface of the vehicle, thereby ensuring the aesthetic appearance of the vehicle's external shape.

[0055] In order to further improve the Y-direction stiffness of the upper longitudinal beam structure mounting area, the reinforcing plate 300 may include a first plate 310 and a second plate 320. The first plate 310 and the second plate 320 may be connected and intersected. The edge of the first plate 310 may be provided with a first ear 311, and the edge of the second plate 320 may be provided with a second ear 321. The first ear 311 and the second ear 321 may be fixedly connected by welding to form a self-welding structure. Of course, the first ear 311 and the second ear 321 may also be fixedly connected by screw connection or the like. The area of ​​the reinforcing plate 300 corresponding to the mounting boss 100 (i.e., the first boss 110) is located at the corner of the reinforcing plate 300 having the first ear 311 and the second ear 321.

[0056] In this case, the area of ​​the reinforcing plate 300 corresponding to the installation area is located at the corner of the reinforcing plate 300 having the first ear 311 and the second ear 321, so that the position of the self-welding structure is adjacent to the installation area, and the distance between the self-welding structure and the installation area is small, which can effectively improve the Y-axis stiffness of the installation area.

[0057] In a further technical solution, the first ear 311 may include a first fitting portion, and the second ear 321 may include a second fitting portion, the first fitting portion and the second fitting portion are fitted and fixedly connected, and the planes where the first fitting portion and the second fitting portion are located are perpendicular to the plane where the first plate 310 is located, and are perpendicular to the plane where the second plate 320 is located. Optionally, the first fitting portion and the second fitting portion may be fixedly connected by welding.

[0058] In this case, on the premise of enhancing the Y-direction rigidity of the installation area, the rigidity of the reinforcing plate 300 itself can also be enhanced. Enhancing the rigidity of the reinforcing plate 300 itself can also further improve the Y-direction rigidity of the installation area.

[0059] When the first plate 310 and the second plate 320 intersect, the first plate 310 and the second plate 320 form an obtuse angle and an acute angle (or a right angle), and the first ear 311 and the second ear 321 can be located in the space of the acute angle (or the right angle) formed by the first plate 310 and the second plate 320. This structure can enhance the rigidity of the reinforcing plate 300, thereby further improving the Y-direction rigidity of the area corresponding to the installation area of ​​the upper longitudinal beam structure.

[0060] In other embodiments, the reinforcing plate 300 may also increase its dimension in the X direction, and the reinforcing plate 300 and the side wall of the vehicle body may be welded together to improve the rigidity of the installation area. However, in this structure, since the welding position between the reinforcing plate 300 and the vehicle body is far from the installation area, compared with the method of forming a self-welding structure at a position of the reinforcing plate 300 adjacent to the installation area to improve the rigidity of the installation area, this method has a smaller improvement in the rigidity of the installation area.

[0061] Based on the above upper longitudinal beam structure, the embodiment of the present application further provides a vehicle, which includes the above upper longitudinal beam structure. Since the vehicle has the above upper longitudinal beam structure, the beneficial effects of the vehicle brought by the upper longitudinal beam structure can be found in the above content, which will not be repeated here.

[0062] The vehicle further includes a hood and a connecting rod hinge 500. The number of the upper longitudinal beam structure and the connecting rod hinge 500 is at least two. The at least two upper longitudinal beam structures are arranged opposite to each other, and the outer side walls of the two upper longitudinal beam structures arranged opposite to each other are separated. The connecting rod hinge 500 is installed in the installation area, and the hood is rotatably connected to the upper longitudinal beam structure through the connecting rod hinge 500. The connecting rod hinge 500 can be a four-link hinge.
