[0028] With the increasing popularity of new energy vehicles, young consumers are becoming more discerning about a car's appearance and performance. To enhance the vehicle's sporty feel, air intake ducts are incorporated into the hood design, highlighting the sporty character and meeting the demands of a youthful design. The hood's air intake duct, a key decorative feature of the vehicle's front end, is integrated into the hood assembly. While ensuring the hood's opening and closing functions, the hood's air intake duct must also consider the cabin's watertightness, NVH, wind resistance, and pedestrian protection requirements to provide a superior driving experience.

[0029] In view of this, in a first aspect, the present disclosure provides a hood structure. Figures 1 to 11 are embodiments of the hood structure provided by the present disclosure, and the hood structure of the present disclosure will be described below with reference to the accompanying drawings.

Figure 10 is a partial structural diagram at C in Figure 4. Figure 11 is a stereoscopic structural diagram of the duct structure in Figure 1.

[0031] Referring to Figures 1 to 11, the hood structure 100 includes a hood body 1 and an air duct structure 2. The hood body 1 is rotatably mounted on a vehicle body 200. The air duct structure 2 includes an air duct body 21 and a flexible sealing structure 22 located at the lower edge of the air duct body 21. The air duct body 21 is mounted at the front end of the hood body 1 and is configured to communicate with a front air duct 201 at the front end of the vehicle body 200 when the hood body 1 is covering the vehicle body 200. The flexible sealing structure 22 is configured to seal the gap between the air duct body 21 and the front air duct 201.

[0032] In the technical solution disclosed herein, in order to enhance the sporty feel of the vehicle body 200, change the traditional appearance of the hood structure of the car, and cater to the needs of young customers, the air duct structure 2 is provided on the cover body 1 of the hood structure 100. Correspondingly, a front guard air duct 201 is provided through the front guard area of ​​the vehicle body 200 to communicate with the air duct structure 2 to form a complete air duct, thereby meeting the structural requirements. In some embodiments, the air duct structure 2 is mounted on the cover body 1, and the cover body 1 is rotatably mounted on the vehicle body 200 to drive the air duct structure 2 to rotate, so that the air duct structure 2 and the front guard air duct 201 on the vehicle body 200 are not fixedly connected. On this basis, during the covering process of the cover body 1, in order to avoid interference between the air duct structure 2 on the cover body 1 and the structure on the vehicle body 200, a certain gap is provided between the air duct structure 2 and the structure on the vehicle body 200. After setting this interval, there will be a gap between the air duct structure 2 and the front air duct 201 on the vehicle body 200, which will affect the watertightness, NVH performance and overall wind resistance of the vehicle cabin, and thus affect the driving experience. In order to improve this problem, the present disclosure proposes to set the flexible sealing structure 22 at the lower edge of the air duct main body 21, so that when the cover body 1 is covered on the vehicle body 200, the flexible sealing structure 22 can deformably seal the gap between the air duct structure 2 and the front air duct 201 on the vehicle body 200. The flexible sealing structure 22 relies on its flexibility to ensure the sealing effect of the vehicle body 200 without affecting the opening and closing of the cover body 1, thereby improving and reducing the problem of the watertightness, NVH performance and overall wind resistance of the vehicle cabin affected by the gap between the air duct structure 2 and the front air duct 201 on the vehicle body 200, so as to achieve the corresponding design purpose and thus enhance the driving experience.

[0033] In some embodiments, the flexible sealing structure 22 includes a flexible skirt 221 disposed around the lower edge of the air duct body 21. The flexible sealing structure 22 is not limited in form and can be a waterproof foam, a sealing rubber ring, or the like, as long as it seals the gap between the air duct structure 2 and the front air duct 201 without affecting the opening and closing of the cover body 1. The flexible skirt 221 structure is employed in some embodiments of the present disclosure.

[0034] In some embodiments, the flexible skirt 221 is integrally formed with the duct body 21. The flexible skirt 221 can be a detachable structure independent of the duct structure 2, or it can be integrally molded with the duct body 21. In some embodiments of the present disclosure, the flexible skirt 221 and the duct body 21 are integrally molded, which can reduce assembly steps and the number of parts, thereby lowering costs. The duct body 21 and the flexible skirt 221 can be integrally molded in a variety of ways, which are not limited herein. In some embodiments of the present disclosure, the flexible skirt 221 and the duct body 21 are integrally molded using two-color injection molding. In some embodiments, the duct body 21 is manufactured using PP-T20 material to ensure its rigid structure. The flexible skirt 221 needs to have a certain degree of flexibility and be capable of being two-color injection molded with the duct body 21. In other embodiments of the present disclosure, the flexible skirt 221 is manufactured using TPV material to meet the above requirements.

[0035] In some embodiments, a drainage hole 222 is provided at the bottom of the flexible skirt 221. Providing the drainage hole 222 at the lowest point of the air duct structure 2 effectively drains any residual water within the housing 1 and the air duct structure 2. In some embodiments, the lowest point of the air duct structure 2 is the flexible skirt 221, located at the lower edge of the air duct body 21. The drainage hole 222 is provided at the bottom of the flexible skirt 221 to meet this requirement.

[0036] In some embodiments, the duct body 21 includes an upper duct assembly 211 and a lower duct assembly 212 distributed vertically. The upper duct assembly 211 and the lower duct assembly 212 are connected by a snap-fit ​​structure 213, and the flexible sealing structure 22 is disposed in the lower duct assembly 212. The duct body 21 can be configured as an integral structure, but considering the complexity of its configuration on the cover body 1 and the structural complexity of its coordination and fixation with the cover body 1, the integral duct body 21 may be inconvenient to install. Therefore, in some embodiments of the present disclosure, the duct body 21 is configured as the upper duct assembly 211 and the lower duct assembly 212 that are mutually connected, so that the upper duct assembly 211 can be installed downward from the top of the cover body 1, and the lower duct assembly 212 can be installed upward from the bottom of the cover body 1. Finally, the upper duct assembly 211 and the lower duct assembly 212 are automatically connected and fixed in the middle by the snap-fit ​​structure 213 to achieve aligned installation. The duct body 21 is installed separately, which can avoid the problem of difficulty in installing the duct body 21 as a whole. On the other hand, the upper duct component 211 and the lower duct component 212 are automatically connected by the clamping structure 213, without the need for manual alignment, which is convenient for installation in a complex structural environment and simplifies the installation and alignment operation.

[0037] In some embodiments, the inner wall of the upper duct assembly 211 extends beyond the inner wall of the lower duct assembly 212 at a position below the junction of the upper duct assembly 211 and the lower duct assembly 212. After the upper duct assembly 211 and the lower duct assembly 212 are snap-fitted together, a seam will exist between them. This seam presents a risk of water accumulation, potentially causing water to seep into the cabin and affecting the NVH performance of the vehicle. Therefore, in some embodiments of the present disclosure, the upper duct assembly 211 is set to extend beyond the down duct assembly 212 at a position below the junction of the upper duct assembly 211 and the down duct assembly 212, that is, the edge of the upper duct assembly 211 is higher than the edge of the down duct assembly 212, so that when water flows along the air duct through the junction of the upper duct assembly 211 and the down duct assembly 212, the water will not accumulate at the junction of the two due to the height difference between the two, thereby avoiding the above-mentioned problem caused by water accumulation at the junction of the two.

[0038] In some embodiments, the height by which the inner wall of the upper duct assembly 211 protrudes above the inner wall of the lower duct assembly 212 is h, where 0 mm < h ≤ 1 mm. To ensure the smoothness of the inner wall of the duct, thereby reducing wind resistance and noise within the duct, the height difference between the upper duct assembly 211 and the lower duct assembly 212 should not be too great. In some embodiments of the present disclosure, the height difference between the upper duct assembly 211 and the lower duct assembly 212 is no greater than 1 mm to minimize wind resistance and noise, thereby improving the driving experience.

[0039] In some embodiments, the lower duct assembly 212 includes a first duct assembly 212a and a second duct assembly 212b distributed in an upper and lower manner. The first duct assembly 212a is arranged in a cylindrical shape, and its lower end is arranged to be flared, and the second duct assembly 212b is inserted into the flared portion. Based on a similar purpose as the duct body 21 being divided into the upper duct assembly 211 and the lower duct assembly 212, that is, to simplify the installation steps and reduce the manufacturing molding cost in a complex structural environment, in some embodiments of the present disclosure, the lower duct assembly 212 is divided into the first duct assembly 212a and the second duct assembly 212b, both of which can be fixedly connected to the cover body 1 respectively. In some embodiments, the first duct assembly 212a and the second duct assembly 212b are connected in a socketed manner, that is, the lower end of the first duct assembly 212a is flared, and the first duct assembly 212a and the second duct assembly 212b are aligned by inserting the second duct assembly 212b into the flared portion. In this way, on the one hand, the structure is simple and the cost is low, on the other hand, the positioning error is small, and on the other hand, the joint between the first air duct component 212a and the second air duct component 212b can be guaranteed to be smooth to avoid increasing wind resistance and wind noise.

[0040] In some embodiments, the front-to-back dimension of the housing 1 is L, and the air duct structure 2 is disposed within the L / 3 region at the front of the housing 1. As mentioned above, the air duct body 21 is manufactured from PP-T20 material. Based on this, in some embodiments of the present disclosure, the air duct structure 2 is located entirely within the front third of the housing 1 to reduce collision damage to pedestrians and thereby enhance overall vehicle safety.

[0041] In some embodiments, an air outlet a is provided on the cover body 1. The air duct structure 2 is provided below the cover body 1, and includes an air duct main body 21 extending in the front-to-back direction and used to connect the front air duct 201 and the air outlet a. The air duct main body 21 includes an upper air duct component 211 and a lower air duct component 212 distributed up and down and connected to each other. The outer peripheral wall of the upper air duct component 211 is provided with a clamping portion 3, and the outer peripheral wall of the lower air duct component 212 is provided with a matching portion 4 that is clamped with the clamping portion 3. A guide portion 5 is provided on the lower air duct component 212, and the guide portion 5 is used to guide the clamping portion 3 to the matching portion 4 when the upper air duct component 211 and the lower air duct component 212 are clamped together.

[0042] It should be noted that since the air outlet a is located above the cover body 1 and the front air duct 201 is located below the air outlet, the air duct body 21 is arranged at an angle as a whole. Therefore, the upper air duct component 211 and the lower air duct component 212 are distributed in the up and down directions and are connected to each other.

[0043] In some embodiments, the outer peripheral wall of the upper duct assembly 211 is provided with a holding portion 3, and the outer peripheral wall of the lower duct assembly 212 is provided with a matching portion 4 that is engaged with the holding portion 3. By arranging the holding portion 3 and the matching portion 4 on the outside of the duct body 21 and engaging them in a holding manner, the upper duct assembly 211 and the lower duct assembly 212 can be fixed, and water can be prevented from being retained in the duct body 21. On the one hand, when disassembly is required, the upper duct assembly 211 can be pulled out with force so that the holding portion 3 is separated from the matching portion 4, making it easy to disassemble the upper duct assembly 211. When the upper duct assembly 211 needs to be blindly installed to the lower duct assembly 212, the holding portion 3 can be guided to the matching portion 4 by the guide portion 5, so that the holding portion 3 can be smoothly engaged with the matching portion 4, thereby solving the problem of blind installation by the operator when assembling and fixing the upper duct section and the lower duct section, which leads to assembly difficulties. On the other hand, the guide portion 5 automatically guides the upper duct assembly 211 and the lower duct assembly 212 to automatically engage with each other, eliminating the need for manual alignment, making installation in a complex structural environment easier and simplifying installation alignment operations.

[0044] Referring to Figures 7 to 9, in some embodiments of the present disclosure, the periphery of the air outlet of the down duct assembly 212 is provided with an outer flange 20, and the outer flange 20 is provided with a through hole 20a extending vertically therethrough. The mating portion 4 is provided below the through hole 20a. The guide portion 5 includes a folded portion 51 extending upward and away from the air outlet of the down duct assembly 212 from the outer flange 20. The retaining portion 3 is provided protrudingly on the periphery of the air inlet of the up duct assembly 211 and extending toward the down duct assembly 212. The retaining portion 3 is used to penetrate the through hole 20a to engage with the mating portion 4.

[0045] When the upper duct assembly 211 and the lower duct assembly 212 need to be assembled, the upper duct assembly 211 can be moved from top to bottom to press the holding portion 3 against the inner side of the folding portion 51 and hold it downward, so that the holding portion 3 can slide along the folding portion 51 toward the outer flange 20, and finally the holding portion 3 can slide to the through hole 20a, pass through the through hole 20a, and be held and matched with the matching portion 4 below the through hole 20a.

[0046] In some embodiments, the folding portion 51 has a first bending section 511 and a second bending section 512 connected in sequence, and the first bending section 511 is connected to the outer peripheral wall of the down duct assembly 212. The angle between the first bending section 511 and the outer peripheral wall of the down duct assembly 212 is a, and the angle between the first bending section 511 and the second bending section 512 is b, wherein 18°≤a≤38°, and 125°≤b≤145°. Because the second bending section 512 first abuts against the clamping portion 3, the first bending section 511 and the second bending section 512 of the folding portion 51 are set and constrained within the above-mentioned angle range, so that the folding portion 51 can have a larger guiding range, thereby allowing the operator to easily assemble the upper duct assembly 211 to the down duct assembly 212.

[0047] It should be noted that the angle a between the first bending section 511 and the outer peripheral wall of the downwind duct assembly 212 is set in the range of 18° to 38°. In some embodiments, a can also be set to 20°, 22°, 24°, 26°, 28°, 30°, 32°, 34°, or 36°. The angle b between the first bending section 511 and the second bending section 512 is set in the range of 125° to 145°. In some embodiments, b can also be set to 127°, 129°, 131°, 133°, 135°, 137°, 139°, 141°, or 143°. It is understood that b needs to be set to be greater than a+90° so that the second bending section 512 can play a guiding role and smoothly guide the clamping portion 3 to the first bending section 511 and the outer flange 20.

[0048] In some embodiments of the present disclosure, the guide portion 5 includes a plurality of folding portions 51, and a plurality of through-holes 20a are provided. The plurality of folding portions 51 and the plurality of through-holes 20a are arranged at intervals along the circumference of the down duct assembly 212. The clamping portion 3 and the matching portion 4 are both provided in plurality, and the plurality of clamping portions 3 are arranged at intervals along the circumference of the upper duct assembly 211, and the plurality of matching portions 4 are arranged at intervals along the circumference of the down duct assembly 212. In this way, by providing a plurality of the clamping portions 3 and a plurality of the matching portions 4, the down duct assembly 212 and the upper duct assembly 211 can be fixed more stably. By providing a plurality of the folding portions 51, each clamping portion 3 can be smoothly guided to the corresponding through-hole 20a.

[0049] In some embodiments of the present disclosure, one of the holding portion 3 and the mating portion 4 includes a slot 3a, and the other includes a buckle 41. The holding portion 3 and the mating portion 4 may also be engaged with each other by means of a hook. The holding portion 3 and the mating portion 4 are not limited to the above examples. Persons skilled in the art may make other modifications based on the technical essence of the embodiments of this specification. However, as long as the functions and effects achieved are the same or similar to those of the embodiments of this specification, they shall be covered by the scope of protection of the embodiments of this specification.

[0050] In some embodiments of the present disclosure, a protrusion 411 is provided on the outer peripheral wall of the down duct assembly 212, and the protrusion 411 forms the buckle. The retaining portion 3 is provided on a portion of the periphery of the air inlet of the upper duct assembly 211, and the retaining portion 3 is provided with the retaining slot 3a extending therethrough. The retaining slot 3a forms a limiting hole, and the inner peripheral wall of the retaining slot 3a limits the peripheral wall of the protrusion 411. The through hole 20a limits the retaining portion 3 on the side facing away from the outer peripheral wall of the down duct assembly 212 to prevent the retaining portion 3 from disengaging from the retaining slot 3a, thereby achieving a locking relationship between the retaining portion 3 and the retaining slot 3a.

[0051] In some embodiments, to facilitate the smooth passage of the clamping portion 3 over the protrusion 411, a guide slope 4111 is provided on the end surface of the protrusion 411. The guide slope 4111 is inclined downward from top to bottom, away from the outer peripheral wall of the down-duct assembly 212. With this arrangement, the lower end of the clamping portion 3 can abut against the guide slope 4111 when moving downward, gradually warping and sliding along the guide slope 4111, and ultimately passing over the protrusion 411, so that the clamping slot 3a is sleeved around the periphery of the protrusion 411.

[0052] In the technical solution disclosed in the present invention, in order to enhance the sporty feel of the vehicle body and change the traditional appearance of the automobile hood structure to cater to the needs of young customers, the air duct structure is provided on the hood body. Correspondingly, a front guard air duct is provided through the front guard area of ​​the automobile body to connect with the air duct structure to form a complete air duct to meet the structural requirements. The air duct structure is installed on the hood body, and the hood body is rotatably installed on the vehicle body to drive the air duct structure to rotate, so that there is no fixed connection between the air duct structure and the front guard air duct on the vehicle body. On this basis, during the covering process of the hood body, in order to avoid interference between the air duct structure on the hood body and the structure on the vehicle body, a certain gap is provided between the air duct structure and the structure on the vehicle body. After the gap is set, there will be a gap between the air duct structure and the front guard air duct on the vehicle body, which will affect the watertightness, NVH performance and overall wind resistance of the vehicle cabin, and thus affect the driving experience. To improve this problem, the present disclosure proposes to provide the flexible sealing structure at the lower edge of the air duct body, so that when the cover is closed on the vehicle body, the flexible sealing structure can deform and seal the gap between the air duct structure and the front air duct on the vehicle body. The flexible sealing structure, relying on its flexibility, ensures the sealing effect of the vehicle structure without affecting the opening and closing of the cover, thereby improving and reducing the problem that the gap between the air duct structure 2 and the front air duct 201 on the vehicle body 200 affects the watertightness, NVH performance and overall wind resistance of the vehicle cabin, thereby achieving the design purpose and improving the driving experience.

[0053] In the second aspect, the present disclosure also provides an automobile, comprising a vehicle body 200 and a hood structure 100. A front air duct 201 is provided at the front end of the vehicle body 200, and the hood structure 100 is rotatably mounted on the vehicle body 200, so that the hood structure 200 has at least a closed state in which it covers the front end of the vehicle body 200. Moreover, when the hood structure 100 is in the closed state, the air duct structure 2 is connected with the front air duct 201 to form an air duct extending from the front end of the vehicle body 200 to the rear and upward to the top of the hood body 1, highlighting the sporty features of the vehicle shape to meet the needs of youthful design. The specific structure of the hood structure 100 refers to the embodiment of the first aspect mentioned above.

[0054] Since the automobile adopts the technical solution of the embodiment of the first aspect above, it has at least all the beneficial effects brought by the technical solution of the embodiment above, which will not be described one by one here.

[0055] The above description is only a preferred embodiment of the present disclosure and does not limit the patent scope of the present disclosure. All equivalent structural transformations made by using the contents of the present disclosure and the drawings under the utility model concept of the present disclosure, or direct / indirect application in other related technical fields are included in the patent protection scope of the present disclosure.
