[0002] As an important exterior component of the front of a car, the hood's surrounding trim not only beautifies its appearance but also provides some protection for components inside the engine compartment. Furthermore, it directly impacts the overall appearance integrity of the vehicle and the perception of the brand image.

[0003] Existing hood trim pieces often incorporate reinforcing brackets to ensure strength. For example, patent CN217074245U discloses a vehicle hood trim piece structure, including a front hood trim piece body and a front hood trim panel assembly, with the hood trim piece bracket and the front hood trim panel assembly connected and disassembled via a snap-fit ​​method. However, in practical use, the above-mentioned trim pieces have the following problems: 1. Additional bracket molds need to be developed, leading to increased costs; 2. Using piercing welding to fix the hood trim piece bracket to the front hood trim piece body requires destructive disassembly if the bracket is damaged, the trim panel needs to be replaced, or internal hood repairs are required, which can cause deformation of the front hood piece body and damage to the paint.

[0004] Another type of hood trim, such as the patent disclosed in publication number CN217347698U, discloses a hood trim and a vehicle. It uses two diagonally arranged arc-shaped limiting ribs to isolate the trim body from the hood. This structure has a single support point. For trims that are large in size or irregular in shape, the middle area and non-diagonal edges are prone to sagging due to gravity or vibration, which may cause indirect contact between the trim body and the hood, and there is still a risk of paint damage. In addition, the installation adopts an interference fit, which is not convenient for disassembly. Utility Model Content

[0005] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide an easy-to-disassemble car hood decorative part. It adopts an array of reinforcing ribs to replace the traditional support frame, which saves the mold development cost of the traditional support frame and enhances the deformation resistance and warping resistance of the decorative part body under the premise of lightweighting, and is suitable for high temperature and vibration conditions in the engine compartment.

[0006] The aforementioned easy-to-install and disassemble car hood trim includes a trim body, at least two fixing seats are fixedly connected inside the trim body, the fixing seats are provided with mounting grooves for installing connecting components, a plurality of evenly distributed reinforcing ribs are fixedly connected to the side wall near the edge inside the trim body, and a groove is provided around the edge on the bottom inner side of the trim body, and sealing tape is provided in the groove.

[0007] Preferably, the longitudinal section of the decorative component body has an outwardly convex arc shape, and the bottom of the reinforcing rib and the inner wall of the decorative component body are fixedly connected by an edge, which forms a groove with the bottom edge of the decorative component body.

[0008] Preferably, the groove depth is 0.3-0.7 mm.

[0009] Preferably, the thickness of the reinforcing rib is 0.5-1mm, the height is 15-20mm, and the spacing between adjacent reinforcing ribs is 3-5mm.

[0010] Preferably, one side of the mounting groove is connected to the end of the fixing seat, and a guide groove is provided at the connection point to facilitate the entry of the connecting components.

[0011] Preferably, the connecting assembly includes a connecting shaft that mates with a mounting groove. An upper baffle and a lower baffle are fixed on the connecting shaft for limiting the engagement with the upper and lower end faces of the mounting groove. An elastic snap-fit ​​connector is fixed below the lower baffle.

[0012] Preferably, a disc-shaped gasket is fixedly connected between the elastic snap-fit ​​connector and the lower baffle.

[0013] Preferably, it also includes a hood, which has a transition groove that matches the edge of the decorative part body. The transition groove has a mounting hole that engages with the connecting component. A buffer pad is provided between the mounting hole and the disc-shaped pad. A boss protruding towards one side of the decorative part body is provided around the mounting hole.

[0014] Compared with the prior art, the beneficial effects of this utility model are: 1. This utility model uses an array of reinforcing ribs to replace the traditional support frame, saving the mold development cost of the traditional support frame, and enhancing the deformation and warping resistance of the decorative part body under the premise of lightweighting, making it suitable for high temperature and vibration conditions in the cabin; through the side-mounted connecting component and the elastic snap-fit ​​connector, the guide groove can be used to quickly position and press to lock it during installation, making the installation simple, requiring no tools throughout the process, and making the operation efficient and reducing labor costs.

[0015] 2. Adding grooves and transition grooves to match the thickness of the sealing tape enables precise embedding and tight fit of the sealing tape. Combined with the buffer gasket to seal around the mounting hole, it forms double protection, effectively preventing moisture and dust from seeping into the cabin. Both the sealing tape and the buffer gasket are made of weather-resistant materials, which are suitable for the complex environment of the cabin and extend the service life of the protection.

[0016] 3. This utility model absorbs high-frequency vibrations generated by vehicle driving and engine operation through the synergistic effect of the elastic recovery force of the disc-shaped gasket and the flexible contact of the buffer gasket. It reduces the collision and friction between the disc-shaped gasket and the boss, and between the connecting components and the mounting groove, avoiding scratches on the hood paint caused by hard contact. In addition, the sealing tape provides vibration damping and cushioning, significantly reducing abnormal noise and improving the quietness of use. Attached Figure Description

[0019] The present invention will be further described below with reference to the accompanying drawings: The directional terms used in the detailed description paragraphs are only for the convenience of those skilled in the art to understand the technical solutions described in this application based on the visual orientation shown in the accompanying drawings. Unless otherwise expressly specified and limited, the terms "setting," "installation," "connection," etc., should be interpreted broadly, and those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0020] like Figures 1 to 9As shown, an easy-to-install and disassemble automotive hood trim includes a trim body 1. The trim body 1 is mainly used to beautify the vehicle's appearance and conceal wiring harnesses and pipes inside the engine compartment. The trim body 1 has at least two fixing seats 102 internally fixedly connected. The fixing seats 102 are provided with mounting grooves 103 for installing connecting components 2. The mounting grooves 103 can accurately position the connecting components 2, restrict their horizontal and vertical displacement, and ensure the accuracy of the snap-fit.

[0021] In this embodiment, one side of the mounting groove 103 is connected to the end of the fixing base 102, facilitating the side-mounted installation of the connecting component 2 and simplifying the assembly process. Furthermore, a guide groove 104 is provided at the connection point to facilitate the entry of the connecting component 2. The end of the guide groove 104 furthest from the mounting groove 103 opens to both sides. In this embodiment, the open end of the guide groove 104 extends 0.5-1mm to both sides, reserving sufficient pre-installation space for the connecting component 2, facilitating the rapid entry of the connecting component 2 into the mounting groove 103, improving installation efficiency, and reducing operational difficulty.

[0022] like Figure 3 and Figure 4 As shown, multiple evenly distributed reinforcing ribs 101 are fixedly connected to the side wall near the edge inside the decorative part body 1. This array-like reinforcing rib structure replaces the original decorative part support frame, saving on mold development costs for the support frame. Simultaneously, it enhances the structural strength and deformation resistance of the decorative part body 1, effectively coping with high temperatures and vibrations in the cabin and preventing edge warping. A groove 105 is provided around the edge on the inner bottom side of the decorative part body 1, and a sealing tape 3 is placed within the groove 105. In this embodiment, the sealing tape 3 is preferably 3M adhesive with release paper. The groove 105 provides an embedding space for the sealing tape 3, enabling precise positioning and preventing it from falling off or shifting. The sealing tape 3 fills the gap between the decorative part body 1 and the cabin cover 5, achieving waterproof and dustproof sealing, and also absorbs minor vibrations, reducing impact noise.

[0023] The longitudinal section of the decorative component body 1 has an outwardly convex arc shape, which enhances the three-dimensionality and aesthetics of the appearance. It also distributes the stress on the decorative component body 1, improving its impact and bending resistance, and is compatible with the curved shape of the hood 5. An edge 106 is fixedly connected between the bottom of the reinforcing rib 101 and the inner wall of the decorative component body 1. The end of the edge 106 away from the inner wall of the decorative component body 1 is inclined downwards. The edge 106 serves two purposes: firstly, it reinforces the installation stability of the reinforcing rib 101, preventing it from falling off under stress; secondly, the edge 106 mates with the bottom edge of the decorative component body 1 to precisely form a groove 105, ensuring the installation accuracy of the sealing tape 3. Furthermore, the edge 106 increases the contact area with the sealing tape 3, increasing the pressure on the adhesive surface, thereby enhancing the adhesion and sealing reliability of the sealing tape 3.

[0024] The thickness of the reinforcing rib 101 is 0.5-1mm, preferably 0.7mm, to balance structural strength with lightweight design, avoiding excessive thickness that increases the weight of the decorative part body 1 or insufficient thickness that loses its reinforcing effect; the height is 15-20mm, preferably 16mm, to ensure that the reinforcing rib 101 can effectively distribute the stress of the decorative part body 1, improve the deformation resistance, and not interfere with the installation of internal components; the spacing between adjacent reinforcing ribs 101 is 3-5mm to ensure uniform stress transmission, avoid local weak areas, provide sufficient heat dissipation space, and effectively prevent deformation and warping of the decorative part body 1.

[0025] like Figure 6 and Figure 7 As shown, the connecting component 2 includes a connecting shaft 202, which cooperates with the mounting groove 103 to achieve rapid positioning and fixation, limiting the horizontal and circumferential displacement of the connecting component 2 and ensuring accurate snap-fit ​​direction; the connecting shaft 202 is fixed with an upper baffle 201 and a lower baffle 203 for limiting cooperation with the upper and lower end faces of the mounting groove 103, that is, the upper baffle 201 and the lower baffle 203 can clamp the upper and lower surfaces of the mounting groove 103, limiting the axial movement of the connecting component 2 and improving connection stability; an elastic snap-fit ​​connector 205 is fixed below the lower baffle 203, which uses its own elastic deformation to achieve rapid snap-fit ​​and disengagement with the mounting hole 502 in the hood 5 without the need for tool assistance. Specifically, the elastic snap-fit ​​connector 205 includes four elastic arms. The free end of each elastic arm is provided with an arc-shaped guide surface and a barbed limiting part. The elastic arm has a certain deformation stroke, and the inclination angle of the barbed limiting part is 30°-45°. The root of the elastic arm is connected to the bottom of the lower baffle 203 through reinforcing ribs to ensure the structural strength for repeated disassembly and assembly. The elastic arm is used to snap into the mounting hole 502 by deformation. The elastic arm can be squeezed to retract and disengage from the mounting hole without tools.

[0026] A disc-shaped gasket 204 is fixedly connected between the elastic snap-fit ​​connector 205 and the lower baffle 203. The disc-shaped gasket 204 uses the elastic restoring force of the arc structure to absorb the vibration energy during vehicle operation, reduce vibration and noise; at the same time, it compensates for the assembly gap, prevents the elastic snap-fit ​​connector 205 from loosening due to vibration, and improves the reliability of the connection.

[0027] like Figure 8 and Figure 9As shown, it also includes a hood 5, which serves as the mounting base for the decorative element body 1. The hood 5 has a transition groove 501 that adapts to the edge of the decorative element body 1. The transition groove 501 is used to achieve precise positioning of the edge of the decorative element body 1, so that the decorative element body 1 is flush with the surface of the hood 5 after installation, improving the consistency of appearance and preventing edge collisions. The transition groove 501 has a mounting hole 502 that engages with the connecting component 2. The mounting hole 502 provides a snap-fit ​​fixing point for the elastic snap-fit ​​connector 205, realizing the detachable connection between the decorative element body 1 and the hood 5. Furthermore, the mounting hole 502 is surrounded by a boss 503 that protrudes to one side of the decorative element body 1. The boss 503 enhances the structural strength around the mounting hole 502, preventing deformation of the hole wall during snap-fit; at the same time, it increases the contact area with the disc-shaped gasket 204, distributing the force and improving the fixing stability.

[0028] During installation, a buffer pad 4 is provided between the mounting hole 502 and the disc-shaped gasket 204. The buffer pad 4 is preferably a rubber gasket. The buffer pad 4 further absorbs the high-frequency vibrations generated by vehicle driving and engine operation, and isolates the disc-shaped gasket 204 from the boss 503, reducing the collision and friction between the disc-shaped gasket 204 and the boss 503, avoiding abnormal noise and scratches on the paint surface of the hood 5; at the same time, it can assist in sealing, preventing moisture and dust from seeping into the engine compartment from around the mounting hole 502, and improving the overall sealing protection level.

[0029] like Figure 10 As shown, in this embodiment, the radius R of the rounded corner between the upper end of the transition groove 501 and the hood 5 is 7-8mm, preferably 7.6mm, and the inclination angle α of the mounting end face of the transition groove 501 is 160-165°. The depth of the groove 105 is 0.3-0.7mm, preferably 0.5mm. The transition groove 501 and the groove 105 cooperate to adapt to the thickness specification of the sealing tape 3, ensuring that the sealing tape 3 can fit tightly against the inner wall of the transition groove 501 after installation, ensuring a sealing effect; at the same time, it ensures that the decorative part body 1 and the hood 5 maintain a close fit with almost zero gap after installation, so that the surface at the connection between the two is flat, without protrusions or depressions.

[0030] During installation, the connecting component 2 is first inserted laterally into the mounting groove 103 through the guide groove 104 at the end of the fixing seat 102, so that the connecting shaft 202 and the mounting groove 103 are precisely matched. The upper baffle 201 and the lower baffle 203 clamp the upper and lower surfaces of the mounting groove 103, completing the pre-installation of the connecting component 2 on the decorative body 1. Then, the buffer pad 4 is sleeved on the outside of the elastic snap connector 205, and the edge of the decorative body 1 is aligned with the transition groove 501 of the hood 5 to achieve preliminary positioning, ensuring that the mounting surface is flush. Finally, the release paper of the sealing tape 3 is torn off, and the decorative body 1 is pressed, so that the elastic snap connector 205 is aligned with the mounting hole 502 and produces elastic deformation. After passing through the mounting hole, it returns to its original shape to complete the snap-fit ​​locking. The boss 503, the buffer pad 4, and the disc-shaped pad 204 are pressed together in sequence to achieve fixation. At this time, the arc structure of the disc-shaped pad 204 generates elastic restoring force to compensate for the assembly gap, and the buffer pad 4 tightly fills the gap of the contact surface.

[0031] The sealing tape 3 inside the groove 105 at the bottom of the decorative part body 1 fits tightly against the inner wall of the transition groove 501. Combined with the sealing effect of the buffer gasket 4 around the mounting hole 502, a double sealing structure is formed. At the same time, the sealing tape 3, the disc-shaped gasket 204, and the buffer gasket 4 work together to absorb slight vibrations and prevent collision noises, thus completing the installation and fixing of the decorative part body 1. The entire process requires no tools, is simple to install, and provides good sealing.

[0032] Finally, although this specification describes embodiments, not every embodiment contains only one independent technical solution. This way of describing the specification is only for clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
