Description

Technical Field

[0001] This invention relates to the field of vehicles, and more particularly to engine hoods and vehicles. Background Technology

[0002] As an exterior covering of the vehicle's front compartment, the hood needs to maintain sufficient strength to prevent dents from external pressure, while also minimizing pedestrian injury in the event of a collision. Balancing these two aspects is a key focus in hood design. Currently, hood designs often compromise pedestrian protection performance while maintaining hood strength, and vice versa.

[0022] The present invention also provides a vehicle comprising the above-described engine hood, the engine hood comprising:

[0023] A machine cover, comprising an outer panel and an inner panel spaced apart in a vertical direction, wherein an air outlet is provided on the outer panel; and...

[0024] An air guiding structure is at least partially disposed between the outer panel and the inner panel. The air guiding structure has a first air outlet, a second air outlet, and an air duct connecting the first air outlet and the second air outlet. The first air outlet is connected to the air outlet, and the second air outlet is used to connect to the air inlet of the air inlet grille.

Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

Additionally, the meaning of "and / or" throughout the text includes three parallel solutions; for example, "A and / or B" includes solution A, solution B, or a solution where both A and B are satisfied simultaneously. Furthermore, the technical solutions of the various embodiments can be combined with each other, but this must be based on the ability of those skilled in the art to implement them. When the combination of technical solutions is contradictory or impossible to implement, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection claimed by this invention.

[0039] As an exterior covering of the vehicle's front compartment, the hood needs to maintain sufficient strength to prevent dents from external pressure, while also minimizing pedestrian injury in the event of a collision. Balancing these two aspects is a key focus in hood design. Currently, hood designs often compromise pedestrian protection performance while maintaining hood strength, and vice versa. Finding a solution that balances increasing hood strength with ensuring adequate pedestrian protection remains a critical challenge in this field.

[0040] To address the aforementioned problems, the present invention provides an engine hood. Figure 1 This is a perspective view of an embodiment of the engine hood provided by the present invention; Figure 2 for Figure 1 A cross-sectional view of line A-A; Figure 3 for Figure 1 A three-dimensional schematic diagram of the air guiding structure in the middle; Figure 4 for Figure 1 An exploded diagram of the air guide structure in the middle; Figure 5 for Figure 1 A schematic diagram of part of the engine hood structure.

[0041] Please see Figures 1 to 4The engine hood 100 includes a hood and an air guide structure 3. The hood includes an outer plate 1 and an inner plate 2 spaced apart in the vertical direction. An air outlet 1a is provided on the outer plate 1. The air guide structure 3 is at least partially disposed between the outer plate 1 and the inner plate 2. The air guide structure 3 has a first air outlet a, a second air outlet b, and an air duct c connecting the first air outlet a and the second air outlet b. The first air outlet a is used to connect with the air inlet of the air inlet grille, and the second air outlet b is connected with the air outlet 1a. The front end of the front air guide section 31 is provided with the first air outlet a, and the rear end of the rear air guide section 32 is provided with the second air outlet b. The air duct c is provided through the front air guide section 31 and the rear air guide section 32. The front air guide section 31 is provided with a retaining part 4, and the rear air guide section 32 is provided with a fastening part 5. The front air guide section 31 and the rear air guide section 32 are secured by the retaining part 4 and the fastening part 5.

[0042] In this embodiment, the air guide structure 3 is located between the outer plate 1 and the inner plate 2, providing a certain support for the outer plate 1. The outer plate 1, as the exterior covering of the engine hood 100, can be set to be slightly thinner. Similarly, the inner plate 2 can also be set to be slightly thinner while ensuring strength.

[0043] It should be noted that the up-down, left-right, and front-back directions defined in this invention are defined relative to the normal placement and driving state of the vehicle. The front of the vehicle is divided into the front and the parking space is the rear. Since the first air vent a of the air guide structure 3 is located in front of the vehicle body and the second air vent b is located in rear of the vehicle body, the front air guide part 31 with the first air vent a is located in front of the rear air guide part 32.

[0044] In the technical solution provided by this invention, the air guide structure 3 is fixed to the hood. Under normal conditions, the air guide structure 3 provides a certain support strength for the hood to ensure the strength of the engine hood 100 under normal conditions. When a vehicle collides with a pedestrian, the air guide structure 3 includes a front air guide 31 and a rear air guide 32 in the front-to-back direction. The front air guide 31 and the rear air guide 32 are held and fixed by the clamping part 4 and the fastening part 5. Under the condition of being subjected to an external force from front to back, the front air guide 31 and the rear air guide 32 are squeezed and undergo a certain deformation to absorb energy, so that the clamping part 4 and the fastening part 5 disengage from each other. The front air guide 31 and the rear air guide 32 can each shift with the deformation of the hood, so that the strength of the air guide structure 3 will not aggravate the injury to the pedestrian, thus solving the problem that the existing engine hood 100 cannot take into account both strength and pedestrian protection safety performance.

[0045] It should be noted that the material of the air guide structure 3 can be set to a material that can produce a certain deformation, such as plastic or metal, so as to ensure that when the cover is subjected to external force, it can easily deform so that the clamping part 4 and the fastening part 5 can be separated.

[0046] Specifically, in this embodiment, one of the holding part 4 and the fastening part 5 includes a buckle, and the other includes a slot. Of course, the holding part 4 and the fastening part 5 can also be a hook and a hook engaging. Naturally, the holding part 4 and the fastening part 5 are not limited to the examples above. Those skilled in the art, inspired by the technical essence of the embodiments in this specification, may make other modifications, but as long as the functions and effects achieved are the same as or similar to those in the embodiments of this specification, they should all be covered within the protection scope of the embodiments of this specification.

[0047] Furthermore, because the air guide structure 3 has a long distance in the front-to-back direction and the cross-section of the air duct is large, in order to ensure that the air guide structure 3 has a certain strength and will not easily deform when airflow passes through or when the vehicle vibrates or shakes, in this embodiment, the front air guide 31 includes a first air guide 311 and a second air guide 312 connected in the front-to-back direction. The rear end of the second air guide 312 is provided with the fastening part 5, and the front end of the first air guide 311 is provided with the first air outlet a. The air duct includes a first air duct 1c that runs in the front-to-back direction and penetrates the first air guide 311, two second air ducts 2c that penetrate the second air guide 312, and a third air duct 3c that penetrates the rear air guide 32. The front ends of the two second air ducts 2c are connected to the rear ends of the first air duct 1c, and the rear ends of the two second air ducts 2c are connected to the front ends of the third air duct 3c. Thus, since the second air guide 312 forms two second air ducts 2c, it means that there is a dividing part in the middle of the second air guide 312, which divides the air duct into two second air ducts 2c. The dividing part is set in a relatively weak part in the middle of the air guide structure 3, which plays a role in strengthening the strength of the air guide structure 3.

[0048] It is understood that the structure of dividing the middle part of the air duct c into two second air ducts 2c can be that a partition plate is set in the middle region of the air duct c, or that a second air duct 2c is formed on two independent components respectively.

[0049] Specifically, in this embodiment, the second air guide 312 includes two housings 3121, each housing 3121 having a second air duct 2c passing through it. The two housings 3121 are arranged at intervals from left to right upwards. This arrangement ensures that the cross-sectional size of each housing 3121 is approximately equal to half the size of the first air outlet a or the second air outlet b, thus enhancing the wind resistance and shock resistance of each housing 3121. To achieve the locking and fixing between the two housings 3121 and the rear air guide 32, multiple fastening parts 5 and multiple locking parts 4 are provided. Each fastening part 5 is locked and fixed to a corresponding locking part 4, and each housing 3121 has at least one locking part 4. It is understood that to maintain a stable connection between each housing 3121 and the rear air guide 32, multiple locking parts 4 are arranged circumferentially around the housing 3121.

[0050] Furthermore, in this embodiment, each of the housings 3121 includes a first housing 3121 and a second housing 3121, which together define a second air duct 2c. A first snap-fit ​​structure (not shown) is provided between the first housing 3121 and the second housing 3121, and the first housing 3121 and the second housing 3121 are held and fixed by the first snap-fit ​​structure. In this way, the connection between the first housing 3121 and the second housing 3121, which is also fixed by snap-fit, can ensure a stable connection between the two under normal use. Under the action of external force, the first housing 3121 and the second housing 3121 can easily detach from each other, so that the support strength of the cover can be instantly released, which is beneficial to the protection of pedestrians.

[0051] It should be noted that the first buckle structure can also be configured with a buckle and a slot for holding, or it can be configured with two hooks for holding. Of course, other possible shapes can also be used. The specific design can be determined according to the actual situation. This specification does not limit this embodiment.

[0052] Furthermore, in this embodiment, a screw connection structure (not shown) is provided between the upper sides of the first air guide 311 and the second air guide 312 at their adjacent ends. The upper end of the first air guide 311 and the upper side of the second air guide 312 are screwed together and fixed by the screw connection structure. Thus, the rigidity of this area is strengthened to a certain extent by the screw connection. It is understood that the screw connection structure can be a screw and threaded hole connection, or a bolt and stud connection, or other possible connection arrangements. The specific method can be determined according to the actual situation, and this embodiment does not limit this.

[0053] Furthermore, the front air guide section 31 and the outer panel 1 are spaced apart in the vertical direction. Thus, since the area corresponding to the front air guide section 31 is relatively far from the outer panel 1 of the hood in the z-direction, there is ample buffer space. The screw connection between the upper end of the first air guide section 311 and the upper side of the second air guide section 312 does not affect the pedestrian protection performance.

[0054] Furthermore, a second snap-fit ​​structure (not shown) is provided between the lower sides of the ends of the first air guide 311 and the second air guide 312 that are close to each other. The lower end of the first air guide 311 and the lower side of the second air guide 312 are held and fixed by the second snap-fit ​​structure. Since the upper sides of the first air guide 311 and the second air guide 312 are fixedly connected, in order to weaken the strength of the first air guide 311 and the second air guide 312 to a certain extent when subjected to external force, the lower sides of the first air guide 311 and the second air guide 312 can also be connected by snap-fit, so that the first air guide 311 and the second air guide 312 can at least partially detach under the action of external force.

[0055] It should be noted that the second buckle structure can also be configured with a buckle and a slot for holding, or it can be configured with two hooks for holding. Of course, other possible shapes can also be used. The specific design can be determined according to the actual situation. This specification does not limit this aspect in the embodiments.

[0056] Specifically, in this embodiment, the upper end of the rear air guide 32 is bonded to the bottom of the outer panel 1. Thus, under normal vehicle use, the rear air guide 32 can be fixed to the bottom of the outer panel 1, maintaining the stability of the air guide structure 3. In the event of a collision between the vehicle and a pedestrian, and the vehicle is subjected to external force, the upper end of the rear air guide 32 can also detach from the outer panel 1, further enhancing pedestrian protection.

[0057] Specifically, please refer to Figure 5 In this embodiment, the inner plate 2 is provided with mounting holes in the vertical direction, and the front air guide 31 passes through the mounting holes. The periphery of the mounting holes limits the circumferential direction of the front air guide 31. In order to ensure the stable connection of the front air guide 31, a third snap-fit ​​structure (not shown) is provided between the lower end of the front air guide 31 and the inner plate 2. The lower end of the front air guide 31 and the inner plate 2 are held and fixed by the third snap-fit ​​structure.

[0058] It should be noted that the third buckle structure can also be configured with a buckle and a slot for holding, or it can be configured with two hooks for holding. Of course, other possible shapes can also be used. The specific design can be determined according to the actual situation. This specification does not limit this embodiment.

[0059] The present invention also provides a vehicle, the vehicle including the engine hood 100 described above, the vehicle also including an engine, body and seats, etc. Since the vehicle includes the engine hood 100, the specific structure of the engine hood 100 refers to the above embodiments. Since the engine hood 100 of this vehicle adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be described in detail here.

[0060] The above description is merely a preferred embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent structural transformations made using the contents of the present invention's specification and drawings under the inventive concept of the present invention, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present invention.
