[0019] Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0020] The following disclosure provides numerous different embodiments or examples for implementing various structures of the invention. To simplify the disclosure, specific examples of components and arrangements are described below. These are merely examples and are not intended to limit the invention. Furthermore, reference numerals and / or letters may be repeated in different examples. Such repetition is for simplification and clarity and does not in itself indicate a relationship between the various embodiments and / or arrangements discussed. Additionally, examples of various specific processes and materials are provided in this invention; however, those skilled in the art will recognize the applicability of other processes and / or the use of other materials.

[0021] Hereinafter, with reference to the accompanying drawings, a front protection system 100 according to an embodiment of the present invention will be described.

[0022] Reference Figures 1-4 The front bumper system 100 includes a bumper 1 and a grille body 2; a grille decoration area 1a is formed in the middle of the bumper 1; the grille body 2 is located on the rear side of the bumper 1 and is provided with a ventilation decoration part 21, the ventilation decoration part 21 is located in the grille decoration area 1a, the arc-shaped front surface 211 of the ventilation decoration part 21 protrudes forward to splice with the arc surface of the bumper 1, and the ventilation decoration part 21 is formed with regularly arranged decorative holes 21a and ventilation holes 21b.

[0023] The grille decorative area 1a is the area formed in the middle of the bumper 1 that accommodates the ventilation decorative part 21. This area matches the shape and design of the ventilation decorative part 21. The ventilation decorative part 21 on the grille body 2 is a part of the grille body 2 that has both ventilation and decorative functions. The decorative holes 21a and ventilation holes 21b provided on it not only meet the ventilation requirements but also enhance the aesthetic appearance. The material of the grille body 2 is not limited. For example, the grille body 2 can be made of PMMA (polymethyl methacrylate, acrylic) + ASA (acrylonitrile-styrene-acrylate terpolymer) blend material.

[0024] The front surface 211 of the ventilation trim 21 protrudes forward, so that the arc-shaped front surface 211 of the ventilation trim 21 and the front surface 211 of the bumper 1 are joined on the same curved surface to form a unified arc surface, creating a smooth overall appearance, which helps to reduce wind resistance. Here, "front side" refers to the direction in which the car is traveling.

[0025] The ventilation decorative section 21 forms regularly arranged decorative holes 21a and ventilation holes 21b. The shapes of the decorative holes 21a and ventilation holes 21b are not limited; for example, the shapes of the decorative holes 21a and ventilation holes 21b can be circular, rectangular, rhomboid, pentagonal, hexagonal, etc. For example, as... Figure 1 As shown, the decorative hole 21a can be a regular hexagon, and the ventilation hole 21b can be a rhombus. The regular arrangement means that the decorative holes 21a and ventilation holes 21b are distributed according to a certain pattern and order, which helps improve ventilation efficiency and makes the front bumper system 100 look neater and more aesthetically pleasing. The form of the regular arrangement is not limited; for example, it can be a row-and-column arrangement, a circular arrangement, a symmetrical arrangement, etc. For example, the main body of the ventilation decorative part 21 can be a rhombus-shaped grille, the rhombus-shaped holes can serve as ventilation holes 21b, and hexagonal holes are formed at the corners of the rhombus, which can serve as decorative holes 21a.

[0026] In the above technical solution, the grille body 2 is located on the rear side of the bumper 1, and the ventilation trim 21 is located in the grille trim area 1a with its arc-shaped front surface 211 protruding forward. Thus, there is no obvious gap at the joint between the grille body 2 and the bumper 1, and the outer frame of the ventilation trim 21 is covered by the bumper 1, forming a frameless appearance of the grille body 2, which helps to reduce wind resistance. The arc-shaped front surface 211 of the ventilation trim 21 protrudes forward and is joined to the arc surface of the bumper 1. The fixing parts can be set on the periphery of the ventilation trim 21 or other parts of the grille body 2, which facilitates the installation and cooperation between the grille body 2 and the bumper 1. The overall arc-shaped joint helps to reduce the problems of warping, loosening or unevenness at the joint between the grille body 2 and the bumper 1. The ventilation trim 21 has decorative holes 21a and ventilation holes 21b, which not only meet the ventilation requirements but also increase the aesthetic appeal.

[0027] Reference Figure 2 , Figure 5 and Figure 6 In some embodiments, a sealing surface 11 is formed on the edge where the bumper 1 and the ventilation trim 21 are joined, and a fixing post 111 is formed on the rear side of the sealing surface 11. A fixing groove 212 is provided at the corresponding position of the ventilation trim 21 and the fixing post 111. The fixing post 111 is located in the fixing groove 212 and the screw 7 passes through the fixing groove 212 to connect with the fixing post 111.

[0028] In the above technical solution, due to the shape of the ventilation trim 21, the splicing seam between the ventilation trim 21 and the bumper 1 is irregular. A sealing surface 11 is formed on the edge where the bumper 1 and the ventilation trim 21 are spliced, thereby filling the splicing seam of the bumper 1 and forming a more regular splicing seam. This reduces the difficulty of splicing the curved surface of the bumper 1 and the ventilation trim 21, and reduces the difficulty of installing and matching the grille body 2 and the bumper 1.

[0029] In the above technical solution, by setting a fixing post 111 on the rear side of the sealing surface 11 and setting a fixing groove 212 at the corresponding position of the ventilation decorative part 21, and the screw 7 passing through the fixing groove 212 to connect with the fixing post 111, a relatively firm fixed connection is provided between the grille body 2 and the bumper 1. The connection is close to the joint between the bumper 1 and the ventilation decorative part 21, so that the joint between the grille body 2 and the bumper 1 is less prone to lifting, loosening or unevenness. When the vehicle encounters bumps or collisions during driving, it is also less prone to loosening or falling off, thus improving the connection strength between the bumper 1 and the grille body 2. The cooperation of the fixing post 111 and the fixing groove 212 provides initial positioning for the installation of the bumper 1 and the grille body 2, improving the installation efficiency.

[0030] Reference Figure 1 and Figure 2 In some embodiments, there are multiple sealing surfaces 11, and decorative beads 5 are embedded in the front side of the sealing surface 11, combined with... Figure 5 , Figure 6 and Figure 7 The sealing surface 11 is provided with a positioning hole 11a, and the decorative bead 5 is provided with a hook 51 on the side facing the sealing surface 11. The hook 51 engages with the positioning hole 11a, and the positioning holes 11a on at least two sealing surfaces 11 are in different positions. The decorative bead 5 is a decorative part 31 embedded in the front side of the sealing surface 11, and its shape can be the same as the shape of the decorative hole 21a. The material of the decorative bead 5 is not limited; for example, the decorative bead 5 can be made of paint-grade ABS (acrylonitrile-butadiene-styrene copolymer).

[0031] For example, 11 sealing surfaces 11 are provided on the upper edge of the bumper 1 where it is spliced ​​with the ventilation trim 21, making the upper edge of the bumper 1 more regular. Decorative beads 5 are embedded on the front side of the sealing surfaces 11. The decorative beads 5 are all the same size, thereby reducing the number of molds and reducing production costs. 6 sealing surfaces 11 are provided on the left and right edges of the bumper 1 where it is spliced ​​with the ventilation trim 21. The left and right edges are symmetrical, and the decorative beads 5 are different sizes.

[0032] In the above technical solution, a decorative bead 5 is embedded on the front side of the sealing surface 11, which can cover the joint between the bumper 1 and the ventilation decoration part 21, making the joint transition more natural; the decorative bead 5 is installed by the engagement of the hook 51 with the positioning hole 11a, making the decorative bead 5 more securely installed and less likely to fall off during vehicle operation, thus improving the reliability and stability of the installation; the positioning holes 11a on at least two sealing surfaces 11 are in different positions, making it less likely for the decorative bead 5 to be installed incorrectly, thus playing a role in preventing mistake-proofing.

[0033] Reference Figure 8 , Figure 9 and Figure 10 In some embodiments, the front bumper system 100 further includes a plurality of decorative blocks 3, which are embedded in the ventilated decorative section 21 and include a decorative section 31 and a ventilated section 32. The decorative section 31 blocks the decorative hole 21a, and the ventilated section 32 forms a through hole 32a that communicates with the ventilated hole 21b. The material of the decorative blocks 3 is not limited. For example, the decorative blocks 3 can be made of paint-grade ABS (acrylonitrile-butadiene-styrene copolymer).

[0034] For example, such as Figure 8 As shown, the front bumper system 100 also includes 6 decorative blocks 3, which are spliced ​​together to cover the ventilation decorative section 21. The decorative section 31 is a regular hexagon and matches the decorative hole 21a. The front surface 211 of the decorative section 31 blocks the decorative hole 21a. The through hole 32a of the ventilation section 32 is rhomboid and matches the ventilation hole 21b and is interconnected.

[0035] In the above technical solution, the decorative block 3 is embedded in the ventilation decorative part 21, and the decorative part 31 blocks the decorative hole 21a. Thus, by designing the shape, color and texture of the decorative part 31, the decorative block 3 and the ventilation decorative part 21 can be matched together, making the front bumper system 100 more visually coordinated and unified, and reducing the abruptness that may be caused when the ventilation hole 21b and the decorative hole 21a exist alone.

[0036] In the above technical solution, the decorative block 3 is provided with a ventilation section 32, and the through hole 32a formed by the ventilation section 32 is connected to the ventilation hole 21b. Thus, air can smoothly enter the engine compartment or other areas that require ventilation through the ventilation hole 21b and the through hole 32a, ensuring that the vehicle can get good heat dissipation and air circulation during driving. In addition, the decorative block 3 is embedded in the ventilation decorative section 21, so that the decorative block 3 and the ventilation decorative section 21 are more firmly connected and can jointly withstand the external forces, reducing the loosening or damage of components due to vibration or collision, and improving the reliability of the front bumper system 100.

[0037] In reference Figure 9 and Figure 10In some embodiments, the decorative block 3 further includes a fixing part 33, which includes a central fixing part 331. The central fixing part 331 is located in the central region of the decorative block 3 and is fixedly connected to the ventilated decorative part 21. The form in which the central fixing part 331 and the ventilated decorative part 21 are fixedly connected is not limited. For example, the central fixing part 331 and the ventilated decorative part 21 can be fixedly connected by means of snap-fit ​​connection, bolt connection, welding, adhesive bonding, etc.

[0038] For example, the front bumper system 100 also includes 6 decorative blocks 3, wherein the decorative block 3 includes a central fixing part 331, the central fixing part 331 is disposed at the corner of the ventilation part 32, and a fixing post can be disposed at the corresponding position of the ventilation decorative part 21, and the central fixing part 331 is connected to the fixing post by screws passing through it.

[0039] In the above technical solution, the setting of the middle fixing part 331 makes the fixing of the decorative block 3 on the ventilation decorative part 21 more stable and close. Since the middle area of ​​the decorative block 3 is a relatively critical and stress-concentrated part, the fixing part 33 is set here to connect with the ventilation decorative part 21, which can improve the reliability of the connection between the decorative block 3 and the ventilation decorative part 21. For example, the force generated by vibration and collision during vehicle driving can prevent the decorative block 3 from loosening or falling off due to uneven force, thus greatly improving the reliability of the installation of the decorative block 3.

[0040] Reference Figure 9 and Figure 10 In some embodiments, the front bumper system 100 further includes a plurality of decorative blocks 3, each decorative block 3 further includes a fixing part 33, the fixing part 33 includes an edge fixing part 332, the edge fixing part 332 is disposed on the edge of the decorative block 3 near the joint between the bumper 1 and the ventilation decorative part 21, the edge fixing part 332 is disposed on the rear side of the fixing groove 212, and the screw 7 passes through the edge fixing part 332 and the fixing groove 212 from back to front to connect with the fixing post 111.

[0041] In the above technical solution, the edge fixing part 332 is located at the edge of the decorative block 3 near the joint between the bumper 1 and the ventilation decorative part 21. This allows the use of the fixing groove 212 and fixing post 111 used to fix the grille body 2 and the bumper 1, thereby reducing the number of connecting parts. The edge fixing part 332 is located behind the fixing groove 212. The screw 7 passes through the edge fixing part 332, the fixing groove 212 and the fixing post 111 from back to front, forming a connection structure of multiple parts of the decorative block 3, the grille body 2 and the bumper 1. This increases the strength and reliability of the connection, making the connection of the decorative block 3, the grille body 2 and the bumper 1 more stable and less likely to fall off during long-term use.

[0042] Reference Figure 11 and Figure 12In some embodiments, the decorative block 3 further includes a positioning part 34, which is provided with a positioning hole 34a, and the ventilated decorative part 21 is provided with a welding insert 213, which is inserted into the positioning hole 34a.

[0043] For example, there are multiple positioning holes 34a, which are provided at the through hole 32a of the ventilation part 32. During assembly, the welding insert 213 on the ventilation decorative part 21 is inserted into the positioning hole 34a, and the ventilation decorative part 21 is fixedly connected to the decorative block 3 by hot melt welding.

[0044] In the above technical solution, the cooperation between the positioning socket 34a and the welding insert 213 provides a positioning reference for the assembly of the decorative block 3 and the ventilation trim 21. During the assembly process, the welding insert 213 can be accurately inserted into the positioning socket 34a, thereby positioning the installation position of the decorative block 3 on the ventilation trim 21, reducing problems such as uneven gaps and misalignment between the decorative block 3 and surrounding components caused by assembly deviations, and improving the overall appearance quality of the front bumper system 100. In addition, after the welding insert 213 is inserted into the positioning socket 34a, it restricts the movement of the decorative block 3 in multiple directions to a certain extent. It can be combined with other connection methods such as screw connection and snap-fit ​​connection to form a multi-layer connection structure, enhance the connection stability between the decorative block 3 and the ventilation trim 21, and reduce the risk of the decorative block 3 loosening or falling off due to vibration, bumps, etc. during vehicle operation.

[0045] Reference Figure 1 and Figure 13 In some embodiments, the front bumper system 100 further includes a decorative strip 4, which extends horizontally along its length and is used to cover the lower edge where the bumper 1 and the ventilation trim 21 meet. The decorative strip 4 can be made of different materials (such as plastic, metal, etc.) and processes (such as electroplating, painting, etc.), and can have various shapes and colors to enhance the vehicle's visual appeal. The installation method of the decorative strip 4 is not limited; for example, it can be a snap-fit ​​connection, screw connection, adhesive bonding, etc. For instance, a fixing post can be provided on the rear side of the decorative strip 4, and the fixing post can be fastened to the fixing components on the grille body 2, trim block 3, and bumper 1 by screws to achieve a fixed installation.

[0046] For example, the front bumper system 100 also includes two decorative strips 4. The lower center of the ventilation trim 21 also includes a license plate suspension part. The two decorative strips 4 are disposed on the left and right sides of the license plate suspension part and are used to cover the lower edge of the joint between the bumper 1 and the ventilation trim 21.

[0047] In the above technical solution, due to the relatively complex structure of the ventilation trim 21 and the irregular lower edge where it connects to the bumper 1, the decorative strip 4 effectively conceals any gaps or unevenness at the joint, making the overall appearance of the front bumper system 100 more streamlined. Furthermore, the decorative strip 4 connects and transitions the bumper 1 and the ventilation trim 21, reducing the abruptness of the joint and making the various components of the front bumper system 100 form an organic whole. Moreover, the decorative strip 4, located at the lower edge of the joint, can protect the bumper 1 and the ventilation trim 21 to a certain extent. During vehicle operation, this area is easily impacted and scratched by road stones, sand, etc., reducing direct damage to the bumper 1 and the ventilation trim 21 and extending their service life.

[0048] Reference Figure 1 and Figure 13 In some embodiments, the front bumper system 100 further includes a tow hook cover 6. A tow hook hole 21c is provided on the upper side of the ventilated trim 21 near the trim strip 4. The tow hook cover 6 covers the tow hook hole 21c and is fixedly connected to the grille body 2. The shape of the tow hook cover 6 matches the tow hook hole 21c on the ventilated trim 21, thereby reducing the impact of the tow hook cover 6 on the overall appearance.

[0049] In the above technical solution, the tow hook plug 6 effectively covers the tow hook hole 21c, making the front bumper system 100 look cleaner and more aesthetically pleasing, and reducing the impact of the tow hook hole 21c on the overall design style of the vehicle's front end. At the same time, while covering the tow hook hole 21c, the tow hook plug 6 does not affect the normal use of the tow hook. When the tow hook is needed, the tow hook plug 6 can be easily removed, thus achieving a combination of functionality and aesthetics. Furthermore, the tow hook plug 6 can prevent dust, sand, rainwater, and other foreign objects from entering the tow hook hole 21c, effectively protecting the tow hook hole 21c and its surrounding structure.

[0050] Reference Figure 14 In some embodiments, the grille body 2 includes a support portion 22, which is adapted to overlap with the headlight bracket 200.

[0051] In the above technical solution, by connecting the support part 22 with the headlight bracket 200, part of the force borne by the grille body 2 can be transferred to the headlight bracket 200, and then further distributed to the body structure by the headlight bracket 200, thereby improving the installation stability of the front bumper system 100.

[0052] The assembly process of the front protection system 100 is described below.

[0053] 1. Several decorative blocks 3 and grille body 2 are pre-positioned and installed on grille body 2 through positioning holes 34a on positioning part 34 and welding inserts 213 on ventilation decorative part 21. The decorative blocks 3 are pre-installed on grille body 2 by hot melt welding. Then the decorative blocks 3 and grille body 2 are fixed by the middle fixing part 331 of the decorative blocks 3. 2. The bumper 1 includes an upper bumper, which is fixed to the grille body 2 by a fixing post 111 and a fixing groove 212, forming an upper front bumper body assembly; 3. The bumper 1 includes a lower bumper, which is attached to the upper front bumper assembly by snap-fit. Then, the trim strip 4 is installed at the lower joint between the lower bumper and the ventilation trim 21. 4. Attach the individual decorative bead 5 to the sealing surface 11 to make the splicing transition more natural, thereby achieving a frameless effect; 5. Cover the tow hook hole 21c with the tow hook plug 6 and fix it to the grille body 2 to complete the assembly of the front bumper system 100. 6. Connect the support part 22 of the front bumper system 100 to the headlight bracket 200 to prevent the grille body 2 from sinking.

[0054] Therefore, the front bumper system 100 integrates the grille body 2 and the bumper 1, allowing for assembly supply and accelerating the final assembly process. Simultaneously, the splicing of the grille body 2 and the bumper 1 is relatively natural, with no obvious seams at the joint. Furthermore, the outer frame of the ventilation trim 21 is concealed by the bumper 1, creating a frameless appearance for the grille body 2, which helps reduce wind resistance. The arc-shaped front surface 211 of the ventilation trim 21 protrudes forward and splices with the arc surface of the bumper 1. Fixing components can be located around the ventilation trim 21 or in other parts of the grille body 2, facilitating the installation and fit between the grille body 2 and the bumper 1. The overall arc-shaped splicing also helps reduce issues such as warping, loosening, or unevenness at the joint between the grille body 2 and the bumper 1. The ventilation trim 21 has decorative holes 21a and ventilation holes 21b, satisfying ventilation requirements while enhancing aesthetics.
