Abstract
Description
Technical Field
[0001] This application relates to the field of automotive technology, and in particular to a headlight and hood assembly structure and an automobile. Background Technology
[0002] Currently, a significant number of cars on the market have hoods that require mechanical struts to open. When it's time to close the hood, the struts retract, and the hood falls naturally under gravity, closing the hood. Figure 1 As shown, for this type of vehicle, the impact force of the hood 2' falling naturally is relatively large, which can impact the engine compartment components 1' and cause damage to them. Engine compartment components 1' typically include headlights, fender trim panels, etc., located under the hood, and these parts are usually made of plastic. To avoid damage to these components from the impact of the hood 2' falling naturally, this type of vehicle is usually designed with a sufficient gap 10' between the hood 2' and these components. However, the existence of gap 10' causes wind noise and whistling noise during driving, affecting the driving experience. One improved solution is to use double-sided tape to attach a separate adhesive strip at gap 10'. While this can alleviate wind noise and whistling noise, its assembly is complex, requiring additional manpower and time, and manual application results in poor product consistency.
[0003] Therefore, it is necessary to propose a new technical solution to overcome the shortcomings of existing technologies. Utility Model Content

The use of the terms "and / or" includes a combination of one or more of the associated listed items.
[0027] Referring to Figure 2 and Figure 3 The application provides a cooperation structure of a headlamp 1 and a hood 2. The cooperation structure comprises the headlamp 1 and the hood 2, the headlamp 1 is arranged below the hood 2, the headlamp 1 comprises a plastic shell, the plastic shell comprises a main body part 11, the main body part 11 has an upper edge, the upper edge is close to the hood 2 and has a clearance gap between the upper edge and the hood 2, wherein the plastic shell further comprises a soft rubber part 12 which is integrally injection molded with the main body part 11 at the upper edge, the soft rubber part 12 shields the clearance gap.
[0028] The application aims to provide a cooperation structure of a headlamp and a hood which is exquisite in design and optimized in function, the cooperation structure improves the appearance of the vehicle, enhances the sealing between components, and reduces wind noise and whistling during driving. The cooperation structure of the headlamp 1 and the hood 2 provided by the application integrally injection molds a soft rubber part 12 at the upper edge of the plastic shell of the headlamp 1, the soft rubber part 12 shields the clearance gap between the hood 2 and the plastic shell, plays a role of protecting the clearance gap of the hood 2, eliminating wind noise and whistling, and improving the appearance. Moreover, compared with the scheme of pasting independent rubber strips, the use of separate rubber strips and 3M double-sided adhesive tape and other auxiliary materials is saved, the labor and time cost in the assembly process is saved, and the consistency of the product is better.
[0029] In the embodiment, the clearance gap is not less than 4 mm. When the clearance gap is too small, the main body part 11 of the plastic shell may be pressed by the hood 2 under the action of gravity when the hood 2 naturally falls, causing damage to the main body part 11. In the embodiment, the clearance gap is set to be 4 mm or more, which can avoid damage to the main body part 11 caused by the hood 2.
[0030] In the embodiment, the main body part 11 is made of hard plastic, and the soft plastic part 12 is made of soft plastic. The main body part 11 is the main part of the plastic shell, which needs to have sufficient strength and stability, and therefore is made of hard plastic material to ensure the stability and durability of the headlamp structure. In an embodiment, the main body part 11 is made of PC material by injection molding. The soft plastic part 12 is made of soft plastic material, which has good elasticity and sealing performance, effectively blocks the clearance, and also has a certain buffering effect when the cover 2 is closed. In an embodiment, the soft plastic part 12 is made of TPE material by injection molding. The main body part 11 and the soft plastic part 12 are two-color injection molded. The two are integrally formed by two-color injection molding technology, which simplifies the production process, ensures product consistency, and makes the combination between the main body part 11 and the soft plastic part 12 more compact. The materials of the main body part 11 and the soft plastic part 12 described above are only an example. Those skilled in the art can select appropriate materials from existing materials to make the main body part 11 and the soft plastic part 12. The specific materials for making the main body part 11 and the soft plastic part 12 are not limited.
[0031] It should be noted that the plastic shell can be one or more of the lamp holder, lampshade or headlamp decoration part of the headlamp 1. That is, those skilled in the art can use the above two-color injection molding process to form a soft plastic part 12 extending to the clearance to block the clearance according to the specific structure of the headlamp 1. In the embodiment, the soft plastic part 12 is formed at least at the upper edge of the main body part 11, i.e. the edge of the cover 2. In other embodiments, the soft plastic part 12 can be further provided at other edges of the main body part 11 to achieve sealing at other positions.
[0032] Please refer to Figure 3 In the embodiment, the soft plastic part 12 includes an elastic arm part 121, and the cover 2 contacts the outer surface of the elastic arm part 121 in the closed state. The structure design of the soft plastic part 12 includes the elastic arm part 121, so that the cover 2 can directly contact the outer surface of the elastic arm part 121 in the closed state, thereby providing a certain buffering effect during the closing of the cover 2. Moreover, since the elastic arm part 121 can be elastically deformed, the contact with the cover 2 will not hinder the cover 2 from closing in place.
[0033] Further, the elastic arm portion 121 extends obliquely from bottom to top, and the outer surface thereof is designed as an arc surface. Such design optimizes the smoothness of the contact and cooperation between the elastic arm portion 121 and the cover 2; in other words, when the cover 2 impacts the elastic arm portion 121 during the closing process, the elastic arm portion 121 will not be squeezed and wrinkled. Moreover, the cover 2 cooperates with the oblique arc surface of the elastic arm portion 121 in the closed state, and the effect of blocking the clearance is better. Meanwhile, the elastic arm portion 121 is provided with an elastic deformation space below, which allows the elastic arm portion 121 to be moderately deformed when subjected to pressure, further improving the adaptability and durability of the structure. In the embodiment, the elastic arm portion 121 is a cantilever, one end of which is connected to the upper edge of the main body portion 11, and the other end is a free end. In other embodiments, the elastic arm portion 121 can also be other structures.
[0034] Please continue to refer to Figure 3 As shown, further, in the embodiment, the main body portion 11 includes an outer plate 111 and a mounting plate 112 extending from the outer plate 111 to the interior of the vehicle body, and the soft rubber portion 12 further includes a connecting portion 122 connected to the mounting plate 112. The outer plate 111 of the main body portion 11 serves to protect the internal components of the headlamp 1 and constitutes the appearance surface of the headlamp 1, and the mounting plate 112 extends to the interior of the vehicle body to provide reliable support and fixation for the fixation and installation of the headlamp 1. The soft rubber portion 12 is connected to the mounting plate 112 through the connecting portion 122, which design increases the area of injection molding connection between the soft rubber portion 12 and the main body portion 11, and strengthens the stability and reliability of the connection between the soft rubber portion 12 and the main body portion 11, so that the soft rubber portion 12 is not easy to break and damage from the main body portion 11. In the embodiment, the overall cross section of the elastic arm portion 121 and the connecting portion 122 of the soft rubber portion 12 is approximately "∴" shaped. In other embodiments, the soft rubber portion 12 can also be other shapes.
[0035] From the above description of the specific embodiments, it can be known that the headlamp 1 and cover 2 cooperation structure provided by the application integrally injection molds a soft rubber portion 12 at the upper edge of the plastic shell of the headlamp 1, the soft rubber portion 12 blocks the clearance between the cover 2 and the plastic shell, and plays a role in cover 2 clearance protection, eliminating wind noise and whistle, and improving the appearance. Moreover, compared with the scheme of pasting independent rubber strips, in the clearance, the headlamp is replaced by a profiled soft rubber structure attached by double-color injection molding, saving the use of separate rubber strips and 3M double-sided adhesive and other auxiliary materials, saving the labor and time cost in the assembly process, and the product consistency is better, perfectly solving the noise problem in high-speed working conditions.
[0036] The application also provides an automobile comprising the cooperation structure of the headlamp 1 and the hood 2 according to any one of the above embodiments. The automobile provided by the application has the beneficial effects of the cooperation structure of the headlamp 1 and the hood 2.

For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described, but it should be understood that any combination of the technical features is within the scope of the present disclosure as long as the combination does not result in contradictions.
[0038] The above embodiments only express several implementation manners of the application, and the description is relatively specific and detailed, but it should not be understood as a limitation on the patent scope of the application. It should be pointed out that, for those skilled in the art, several modifications and improvements can be made without departing from the concept of the application, and these are within the protection scope of the application. Therefore, the patent protection scope of the application should be subject to the appended claims.
