[0038] Through the above-mentioned drawings, the definite embodiment of the present application has been shown, and more detailed description will be given hereinafter.These drawings and textual description are not intended to limit the scope of the concept of the present application by any means, but to illustrate the concept of the present application to those skilled in the art by referring to specific embodiments. DETAILED DESCRIPTION

[0039] The exemplary embodiments will be described in detail hereinbelow with reference to the drawings. When the following description refers to the drawings, identical numbers on different drawings represent the same or similar elements unless otherwise indicated. The implementations described in the following exemplary embodiments do not represent all implementations consistent with the present application. Instead, they are merely examples of apparatuses and methods consistent with some aspects of the present application as detailed in the appended claims.

[0040] In order to meet the comfort requirements of the consumer driving space, some manufacturers set the C point (the position of the driver's hips) close to the front of the vehicle in the vehicle design, so that the space in the front of the vehicle is shortened. If the traditional structure is still used for the front engine compartment hinge, the engine cover may interfere with other parts of the vehicle during opening and closing.

[0041] Therefore, the hinge assembly and the vehicle are provided. The hinge connecting piece has a curved connecting piece, which can adapt to different installation angles and positions. The curved connecting piece encloses an avoidance space, which can effectively utilize the limited space inside the vehicle, so as to solve the problem of interference between the engine cover and other structures of the vehicle during opening and closing when the space in the front of the vehicle is insufficient.

[0042] In one aspect, the present application provides a hinge assembly applied to a vehicle. The vehicle has a cover 210 and a flow guide groove plate. The vehicle can be a fuel vehicle, or the vehicle can also be an electric vehicle. The electric vehicle can be a pure electric vehicle (PEV / BEV), a range extended electric vehicle (REEV), a hybrid electric vehicle (HEV), a fuel cell electric vehicle, or any vehicle with a battery.

[0043] Reference Figures 1 to 8 The hinge assembly 100 can include a first connecting assembly 110, a second connecting assembly 120, and a curved connecting piece 130.

[0044] The first connecting assembly 110 is adapted to be fixedly connected with the flow guide groove plate 220. For example, the first connecting assembly 110 and the flow guide groove plate 220 can be respectively provided with mounting holes and corresponding fixing holes, and the first connecting assembly 110 and the flow guide groove plate 220 are fixed by fasteners passing through the mounting holes and the fixing holes. Alternatively, part of the structure of the first connecting assembly 110 can be directly welded and fixed with the flow guide groove plate 220.

[0045] The second connecting assembly 120 is adapted to be fixedly connected with the cover 210. For example, the second connecting assembly 120 and the cover 210 can also be respectively provided with mounting holes and corresponding fixing holes, and the second connecting assembly 120 and the cover 210 are fixed by fasteners passing through the mounting holes and the fixing holes. Alternatively, part of the structure of the second connecting assembly 120 can be directly welded and fixed with the cover 210. So that the cover 210 and the flow guide groove plate 220 are connected through the hinge assembly 100.

[0046] The curved connecting piece 130 can include a first connecting end 131 and a second connecting end 132, and a clearance space 133 is formed between the first connecting end 131 and the second connecting end 132. For example, the curved connecting piece 130 can include a curved portion with an arc, and the first connecting end 131 and the second connecting end 132 are respectively formed at two ends of the curved portion. In other words, the curved connecting piece 130 can be formed in a structure similar to a "C" letter, and the clearance space 133 is enclosed inside the curved portion. In this way, the structure between the first connecting piece and the second connecting piece of the hinge assembly 100 can be avoided from interfering with other parts of the vehicle, such as the flow guide groove plate 220, during the opening and closing rotation of the cover 210. Alternatively, in addition to the curved portion, the curved connecting piece 130 can also include two straight segments, and the two straight segments are respectively located at two ends of the curved portion. In addition, one end of each of the two straight segments, which is away from the curved portion, respectively constitutes the first connecting end 131 and the second connecting end 132. At this time, the curved connecting piece 130 has a structure similar to a "U" letter, and the clearance space 133 is formed inside the two straight segments and the curved portion. In this way, the clearance space 133 is larger, which is beneficial to match different models of vehicles and expand the adaptation range of the hinge assembly 100.

[0047] The first connecting end 131 is rotationally connected with the first connecting assembly 110. For example, the first connecting end 131 can be hingedly connected with the first connecting assembly 110, or the first connecting end 131 can be connected with the first connecting assembly 110 through a gear. The second connecting end 132 is fixedly connected with the second connecting assembly 120. For example, the second connecting end 132 can be welded and fixed with the second connecting assembly 120, or the second connecting end 132 can be fixedly connected with the second connecting assembly 120 through a bolt and a nut.

[0048] In the prior art vehicle design, in order to meet the comfort requirement, the C point of the vehicle is arranged close to the front part of the vehicle, so that the position of the hinge mounting point of the cover of the front engine compartment is increasingly upwardly moved, which increases the height difference between the position of the connecting point on the vehicle body and the position of the hinge mounting point. Therefore, the position of the connecting point on the vehicle body must be correspondingly upwardly moved. Under this design, through the hinge connection of the prior art, the cover is extremely easy to interfere and collide with the flow guide groove plate under the front windshield of the vehicle during the opening and closing process.

[0049] In the embodiment, the curved connecting piece 130 of the hinge assembly 100 has a certain height, which can meet the requirement that the connecting point on the vehicle body is located lower when the hinge mounting point of the hood 210 is located higher. In addition, part of the structure of the guide groove plate 220 (such as the structure near the connecting point on the vehicle body near the lower part of the guide groove plate 220) is located in the avoiding space 133 of the curved connecting piece 130. In this way, during the opening and closing of the hood 210, the curved connecting piece 130 rotates, and the area where the guide groove plate 220 can interfere with the hinge assembly 100 is located in the avoiding space 133, thereby improving the structural reliability of the vehicle.

[0050] The hinge assembly 100 of the utility model, first connecting assembly 110 and guide groove plate 220 fixed connection, with second connecting assembly and hood 210 are connected to, so that hood 210 and guide groove plate 220 are connected. Due to the design of the curved connecting piece 130, the hinge assembly 100 can adapt to different installation angles and positions, and can be flexibly matched with different vehicle models. The avoiding space 133 is enclosed by the curved connecting piece 130, which can effectively utilize the limited space inside the vehicle, and part of the structure of the guide groove plate 220 is located in the avoiding space 133, thereby reducing the interference between the hood 210 and the guide groove plate 220 during rotation, which is beneficial to prolong the service life of the vehicle. In addition, the hinge assembly 100 of the utility model is of an integral structure, and compared with the single-shaft hinge or the multi-link hinge of the prior art, the hinge assembly has fewer components and is faster to install, which is beneficial to improve the production efficiency of the vehicle.

[0051] Reference Figure 1 , Figure 2 and Figure 8 In some embodiments, the guide groove plate 220 has a first surface 220a and a second surface opposite along the thickness direction of the guide groove plate 220, and a communication hole 221 penetrating the first surface 220a and the second surface is arranged on the guide groove plate 220 to provide installation space for the first connecting assembly 110.

[0052] The first connecting assembly 110 is arranged on the first surface 220a, and the first connecting end 131 is connected to the first connecting assembly 110 by penetrating the communication hole 221 from the side of the second surface. In this way, the curved structure of the curved connecting piece 130 of the hinge assembly 100 is matched, so that the installation of the hinge assembly 100 is more compact, the vehicle will not have part interference during the opening and closing of the hood 210, and the space in the front part of the vehicle is saved. This is beneficial for designers to design the front part of the vehicle individually, thereby improving the attraction to users.

[0053] Reference Figure 1 , Figure 2 and Figure 8In some embodiments, the first connecting assembly 110 can include a first mounting plate 111, at least part of the structure of the first mounting plate 111 protrudes towards a direction away from the deflector plate 220 and forms a receiving cavity 111a. For example, part of the structure of the first mounting plate 111 can protrude to form a housing, and the receiving cavity 111a is in the housing. Alternatively, the entire first mounting plate 111 can protrude to form a housing, and the receiving cavity 111a is in the housing. The housing is arranged in the communication hole 221 to save installation space. The cavity wall of the receiving cavity 111a includes two opposite mounting walls 111b, and the first connecting hole 111c is formed in each of the mounting walls 111b. The first connecting end 131 is provided with a first matching hole 1311, the first matching hole 1311 penetrates the first connecting end 131, and corresponds to the first connecting hole 111c. The first connecting piece passes through the first connecting hole 111c and the first matching hole 1311, so that the curved connecting piece 130 is rotatably connected with the first connecting assembly 110. In this way, the connection between the first connecting assembly 110 and the deflector plate 220 is compact and convenient to install.

[0054] Optionally, the first connecting piece can include but is not limited to a pin shaft, and the pin shaft is matched to rotatably connect the first connecting assembly 110 and the deflector plate 220, which is beneficial to save equipment cost.

[0055] Reference Figure 2 According to some embodiments of the present application, part of the structure of the first mounting plate 111 forms a first bridging portion 111d, the first bridging portion 111d is arranged in the first connecting hole 111c, and the first bridging portion 111d is located at one end of the mounting wall 111b along the first direction. The first bridging portion 111d is connected with the two mounting walls 111b respectively, and the first direction can be a direction parallel to the length direction of the mounting wall 111b. During the opening and closing of the cover 210, the curved connecting piece 130 rotates around the axis of the first connecting piece, and the two mounting walls 111b are the main force bearing structure. The two mounting walls 111b are connected through the first bridging portion 111d, which is beneficial to disperse the load, avoid deformation and damage of the mounting wall 111b due to excessive stress, and has the effect of strengthening the structural strength of the first connecting assembly 110, thereby prolonging the service life of the hinge assembly 100.

[0056] Optionally, the first bridge portion 111d can be two extension sections of the mounting wall 111b opposite to each other in the length direction, and the two extension sections are bent by a certain angle (e.g., 90°) towards the other mounting wall 111b, so that the two extension sections are stacked to form the first bridge portion 111d, and the first bridge portion 111d can be located in a direction perpendicular to the mounting wall 111b, so that the first bridge portion 111d and the two mounting walls 111b enclose the first connecting end 131, thereby improving the structural strength of the shell with the accommodating cavity 111a. Of course, the first bridge portion 111d can also be a first bridge section extending in the axial direction of the first connecting piece, and the two ends of the first bridge section are connected with the two mounting walls 111b respectively, so that the first bridge portion 111d and the two mounting walls 111b form an integral structure and play a role in dispersing load.

[0057] With reference to Figure 2 and Figure 8 According to some embodiments of the present application, part of the structure of the first mounting plate 111 (e.g., the end face opposite to the first connecting end 131) forms a second bridge portion 111e, and the second bridge portion 111e is located at one end of the mounting wall 111b in a second direction, and the second direction can be the height direction of the mounting wall 111b, and the first direction and the second direction are perpendicular. The two ends of the second bridge portion 111e are connected with the two mounting walls 111b respectively, and the load is dispersed through the second bridge portion 111e, thereby further improving the structural stability of the mounting wall 111b.

[0058] When the cover 210 is opened or closed, the second bridge portion 111e can be located in the rotation direction of the curved connecting piece 130, and the second bridge portion 111e has a limiting protrusion 111f protruding towards the first connecting end 131 of the curved connecting piece 130, and the limiting protrusion 111f is suitable for limiting cooperation with the curved connecting piece 130, that is, when the cover 210 is opened and rotated to the limit position, the side wall of the first connecting end 131 abuts against the limiting protrusion 111f, so as to avoid interference between the cover 210 and the flow guide groove plate 220 caused by over-rotation, thereby improving the structural reliability of the vehicle.

[0059] With reference to Figure 2According to some embodiments of the present application, the first mounting plate 111 can further include two first connecting plate segments 111g, the two first connecting plate segments 111g are attached to and connected with the flow guide groove plate 220, and the included angle γ between the mounting wall 111b and the first connecting plate segment 111g satisfies: γ≥90°. Exemplarily, the included angle γ between the mounting wall 111b and the first connecting plate segment 111g can be 90°, 100°, 110°, 120°, 130°, 140°, 150°, 160°, 170° or 180°. Preferably, the included angle γ between the mounting wall 111b and the first connecting plate segment 111g can be 90°. In this way, the included angle γ between the mounting wall 111b and the first connecting plate segment 111g is an angle greater than an acute angle, so as to facilitate sheet metal processing of the first mounting plate 111 to form the accommodating cavity 111a. At the same time, deformation of the two mounting walls 111b towards each other under stress is avoided, and the structural reliability of the first connecting assembly 110 is reduced.

[0060] With reference to Figure 2 and Figure 8 According to some embodiments of the present application, a first mounting hole 111h is formed in the first connecting plate segment 111g, the flow guide groove plate 220 is provided with a first fixing hole corresponding to the first mounting hole 111h, and a second connecting piece passes through the first mounting hole 111h and the first fixing hole to fixedly connect the first connecting assembly 110 and the flow guide groove plate 220. When the hinge assembly 100 of the present embodiment is installed, the first splicing plate segment is arranged on the second surface of the flow guide groove plate 220, the first mounting hole 111h and the first fixing hole are aligned, the shell with the accommodating cavity 111a passes through the communication hole 221 to the first surface 220a, and the second connecting piece passes through the first mounting hole 111h and the first fixing hole to fixedly connect the first connecting assembly 110 and the flow guide groove plate 220. In this way, the connection between the first connecting assembly 110 and the flow guide groove plate 220 is convenient to install, the first connecting assembly 110 and the flow guide groove plate 220 are installed compactly, and the utilization rate of the space in the front part of the vehicle is improved.

[0061] Optionally, the second connecting piece can include, but is not limited to, a pin, a screw, a screw or a bolt nut, so as to save equipment cost.

[0062] With reference to Figure 3In some embodiments, the second connecting assembly 120 can include a second mounting plate 121 provided with a second mounting hole 121a, the bonnet 210 is provided with a second fixing hole corresponding to the second mounting hole 121a, and a third connecting piece passes through the second mounting hole 121a and the second fixing hole to fixedly connect the second connecting assembly 120 and the bonnet 210. By providing the second mounting hole 121a on the second mounting plate 121 and the corresponding second fixing hole on the bonnet 210, the third connecting piece can be directly fixed by passing through the second mounting hole 121a and the second fixing hole, thus simplifying the installation process of the bonnet 210 and facilitating the reduction of the installation time and complexity of the bonnet 210, thereby improving the assembly efficiency of the vehicle. This connection mode makes it more convenient to disassemble and maintain the bonnet 210, and only the third connecting piece needs to be disassembled to overhaul or replace the parts on the bonnet 210, thereby reducing the maintenance cost and time of the vehicle and facilitating the improvement of user satisfaction.

[0063] Optionally, the third connecting piece can include, but is not limited to, a pin, a screw, a screw or a bolt nut, so as to save equipment cost.

Exemplarily, the second connecting plate segments can be oppositely two ends of the second mounting plate 121 formed by bending the sheet metal. The second connecting plate segments 121b are welded with the side wall of the second connecting end 132, thus increasing the contact area between the second mounting plate 121 and the second connecting end 132, ensuring the firm combination of the second connecting plate segments 121b and the second connecting end 132, providing higher connection reliability, and prolonging the service life of the vehicle. Moreover, the second connecting plate segments 121b are welded and fixed with the second connecting end 132 by bending, which helps to disperse stress and reduce stress concentration phenomenon, thereby reducing the risk of fatigue damage and improving the durability of the connecting part.

[0065] Optionally, the second mounting plate 121 can further have a third bridging portion, the third bridging portion is spacedly arranged between the second connecting end 132, and the two ends of the third bridging portion are respectively fixedly connected with the two second connecting plate segments 121b. Thus, the two second connecting plate segments 121b and the third bridging portion enclose the second connecting end 132, which plays a role in dispersing the load of the bonnet 210 on the second connecting assembly 120 during opening and closing, and improves the structural strength of the second connecting assembly 120.
