[0060] In addition, in the present invention, the upper protection body 3 and the lower protection body 1 are connected at both ends by an assembly structure respectively; the setting of the assembly structure facilitates the connection between the upper protection body 3 and the lower protection body 1; in the present invention, the upper protection body 3 and the lower protection body 1 are mainly locked and fixed at both ends, and the middle part is overlapped and installed through the front grille 2.

[0061] In addition, in the present invention, the front grille 2 is arranged between the upper guard body 3 and the lower guard body 1, and the front grille 2 is overlapped on the upper guard body 3 and the lower guard body 1; in the present invention, the front grille 2 has one function for air intake in the front cabin of the car, and another function for reducing the wind resistance of the front guard. At the same time, in the present invention, the front grille 2 also plays a connecting role, which is mainly used for the overlap and fixation between the upper guard body 3 and the lower guard body 1.

[0062] In addition, in the present invention, the upper end of the front grille 2 is clamped on the upper guard body 3, and the lower end of the front grille 2 is connected to the lower guard body 1; such a configuration facilitates the connection and installation of the upper guard body 3 and the middle area of ​​the lower guard body 1.

[0063] At the same time, a fog lamp bracket 5 is provided on the upper guard body 3 in the present invention. The essential function of the fog lamp bracket 5 is to be used for the subsequent installation and assembly of the fog lamp. In the present invention, the fog lamp bracket 5 is connected to the front guard body 1-1 through a clamping component; the clamping component includes a clamping buckle arranged on the upper guard body 3 and a clamping groove arranged on the tail light bracket; the basic function of the fog lamp bracket 5 is to be used for the installation and fixation of the front fog lamp on the front guard body 1-1, and in the present invention, the fog lamp bracket 5 also plays a good reinforcing and supporting role, which is mainly used to ensure the strength of the left and right sides of the front guard body 1-1.

[0064] In addition, the fog lamp bracket 5 in the present invention is arranged at the corner of the upper protection body 3; the present invention adopts such an arrangement to ensure the structural strength of the corner of the fog lamp bracket 5.

[0065] Furthermore, the assembly structure described in the present invention includes a positioning mechanism and a fixing mechanism; the positioning mechanism and the fixing mechanism of the present invention are mainly used for connecting the upper protection body 3 and the lower protection body 1, so as to facilitate the installation and fixation of both ends of the upper protection body 3 and the lower protection body 1.

[0066] Specifically, the positioning mechanism in the present invention includes a longitudinal positioning plate 111 arranged on the lower protection body 1 and a positioning hole arranged on the upper protection body 3; a positioning pin 114 is provided on the longitudinal positioning plate 111; the lower protection body 1 is plugged into the upper protection body 3 through the positioning pin 114; such a setting facilitates the lateral plug-in positioning of the lower protection body 1 on the upper protection body 3.

[0067] In addition, the fixing mechanism in the present invention includes a lower transverse support plate 112 arranged on the lower protection body 1 and an upper transverse support plate 113 arranged on the upper protection body 3, and the upper protection body 3 is arranged on the lower transverse support plate 112 on the lower protection body 1 through the upper transverse support plate 113; such a setting, through the support of the upper transverse support plate 113 by the lower transverse support plate 112, it is possible to realize the installation of the upper protection body 3 on the lower protection body 1; at the same time, the lower protection body 1 can provide longitudinal support to the upper protection body 3.

[0068] In addition, in the present invention, the longitudinal positioning plate 111 is arranged along the longitudinal direction of the vehicle, and the upper transverse support plate 113 and the lower transverse support plate 112 are arranged along a parallel horizontal plane. Based on this design, a relative fixing mechanism between the upper protection body 3 and the lower protection body 1 can be realized in multiple directions, thereby better ensuring the installation stability between the upper protection body 3 and the lower protection body 1.

[0069] In addition, in step 4 described in the present invention, it is required that the positioning pin 114 on the lower protection body 1 is first inserted into the positioning hole on the upper protection body 3; and then the upper protection body 3 and the lower protection body 1 are fixed by fasteners passing through the upper horizontal support plate 113 and the lower horizontal support plate 112; based on such a setting, the present invention enables the upper protection body 3 and the lower protection body 1 to have a pre-positioning effect, which is convenient for the subsequent fasteners to be connected on the lower horizontal support plate 112 and the upper horizontal support plate 113; and avoids the misalignment of the holes on the lower horizontal support plate 112 and the upper horizontal support plate 113 to affect the connection of the fasteners.

[0070] In addition, before the lower guard body 1 is connected to the front grille 2 in the present invention, it is required that the positioning pin 114 in the assembly structure on the upper side of the lower guard body 1 has been inserted into the positioning hole of the upper guard body 3; based on such an operation method, the present invention can achieve pre-positioning of the lower guard body 1 and the front grille 2 before being snapped together, which is equivalent to that one end of the lower guard body 1 has been connected to the front grille 2 through the upper guard body 3, which is conducive to ensuring the accuracy of installation of the front grille 2 and the lower guard body 1.

[0071] In addition, in step 4 described in the present invention, it is required that the lower guard body 1 and the upper guard body 3 are first positioned by the positioning mechanism, and then the lower guard body 1 is clamped on the front grille 2; the essence here is to first limit the position of the lower guard along the Y direction of the whole vehicle, and then lock and fix the lower guard body 1 and the front grille 2. This operation method can well ensure the installation stability between the lower guard body 1 and the front grille 2.

[0072] Furthermore, in the present invention, the side of the upper horizontal support plate 113 on the upper protection body 3 is pressed against the side of the longitudinal positioning plate 111; based on such a configuration, the longitudinal positioning plate 111 can limit the end of the upper horizontal support plate 113, thereby ensuring the alignment operation of the ends of the upper protection body 3 and the lower protection body 1, facilitating the stability of the relative installation of the upper protection body 3 and the lower protection body 1, and avoiding relative movement between the upper protection body 3 and the lower protection body 1.

[0073] Furthermore, in the present invention, a positioning structure is provided between the upper protection body 3 and the front grille 2. The positioning structure is provided mainly to ensure the stability of the installation position between the upper protection body 3 and the front grille 2, while avoiding relative movement between the upper protection body 3 and the front grille 2. In other words, the positioning structure of the present invention can achieve the relative position limitation between the upper protection body 3 and the front grille 2.

[0074] Specifically, the positioning structure in the present invention includes a front guard positioning end plate 31 arranged on the front guard body 1-1 and a grille positioning end plate 21 arranged at the end of the grille body 201; the front guard positioning end plate 31 and the grille positioning end plate 21 are arranged in close contact with each other, and the end of the front grille 2 is pressed against the front guard positioning end plate 31 through the grille positioning end plate 21; the present invention can ensure the fit between the upper guard body 3 and the end of the front grille 2 through the coordinated use of the front guard positioning end plate 31 and the grille positioning end plate 21, and play a role in relative positioning and limiting. In addition, in the present invention, the front guard positioning end plate 31 is arranged perpendicular to the upper guard body 3, and the grille positioning end plate 21 is arranged perpendicular to the grille body 201; such a setting facilitates the relative position limitation between the front grille 2 and the upper guard body 3.

[0075] Furthermore, in step 2 described in the present invention, after the upper guard body 3, the front grille 2 and the outer decorative strip are assembled, screws are passed through the front guard positioning end plate 31 on the upper guard body 3 and the grille positioning end plate 21 on the front grille 2 to connect with the end of the outer decorative strip; such a setting can realize the locking and fixation of the upper guard body 3, the front grille 2 and the outer decorative strip, and the upper guard body 3, the front grille 2 and the outer decorative strip have a mutual positioning function, which can ensure the accuracy of the assembly position of the three.

[0076] Furthermore, in the present invention, the longitudinal positioning plate 111 and the lower transverse support plate 112 are staggered; the longitudinal positioning plate 111 is arranged perpendicular to the lower transverse support plate 112; based on such a setting, the longitudinal positioning plate 111 and the lower transverse support plate 112 have a certain offset, which is convenient for subsequent use, and the longitudinal positioning plate 111 is against the side of the upper transverse support plate 113, thereby realizing the relative position limitation and calibration of the upper protection body 3 and the lower protection body 1.

[0077] Furthermore, in the present invention, the front grille 2 is overlapped on the side of the upper guard body 3 away from the vehicle body, and the lower guard body 1 is overlapped on the end of the front grille 2 away from the upper guard body 3; and is located on the side of the grille away from the vehicle body; based on such a setting, the front grille 2 is equivalent to being overlapped on the outer side of the upper guard body 3, and the lower side of the front grille 2 is overlapped on the inner side of the lower guard body 1. Based on such a setting, it is convenient to overlap and install the upper guard body 3, the front grille 2 and the lower guard body 1 in sequence, and it is convenient for the subsequent assembly operation of the front guard body 1-1.

[0078] In addition, in the present invention, the overlap between the front grille 2 body and the upper protection body 3 has a license plate structure, which ensures the strength of the license plate area for subsequent vehicle installation.

[0079] Furthermore, in the present invention, the front grille 2 includes a grille body 201, and the grille body 201 is provided with overlapping flanges around its periphery; the overlapping flanges are provided with grille buckles or grille slots; generally, a grille buckle is provided above the grille body 201, and a grille slot is provided below the grille body 201; in the present invention, the upper part of the grille body 201 is clamped in the corresponding slot of the upper guard body 3 through the grille buckle, and the lower guard body 1 is clamped in the grille slot below the grille body 201 through the corresponding buckle.

[0080] At the same time, the overlapping flange in the present invention includes an upper overlapping flange and a lower overlapping flange 22; the upper overlapping flange is arranged close to the upper guard body 3; the lower overlapping flange 22 is arranged on the side close to the lower guard body 1; based on such a setting, the overlapping installation between the front grille 2 and the upper guard body 3 and the lower guard body 1 is facilitated.

[0081] Furthermore, the upper overlapping flange in the present invention includes a left overlapping flange 23 and a right overlapping flange 231, and the overlapping flange and the right overlapping flange 231 are symmetrically distributed on the grille body 201. The setting of the left overlapping flange 23 and the right overlapping flange 231 in the present invention facilitates the connection between the left and right sides above the front grille 2 and the upper protection body 3.

[0082] Meanwhile, in the present invention, a license plate 24 is also provided on the grille body 201; the license plate 24 mainly has two functions, one is used for overlapping between the front grille 2 and the upper protection body 3, and the other is used for subsequent installation of the license plate 24.

[0083] In addition, in the present invention, both ends of the license plate 24 are connected to the left overlapping flange 23 and the right overlapping flange 231 respectively through connecting plates; the license plate 24 is arranged in overlapping connection with the upper protection body 3; the license plate 24 and the left overlapping flange 23 and the right overlapping flange 231 are staggered; the staggered distribution here means that the distance between the license plate 24 and the front end of the vehicle body is greater than the distance between the left overlapping flange 23 and the right overlapping flange 231 and the front end of the vehicle body. Such a setting forms a staggered relationship between the license plate 24 and the left overlapping flange 23 and the right overlapping flange 231, thereby forming a stepped structure, which is convenient for limiting the position of the upper protection body 3 during subsequent use, and avoiding shaking or movement of the upper protection body 3 and the front grille 2 along the Y direction of the vehicle.

[0084] In addition, in the present invention, when the upper guard body 3 and the front grille 2 are assembled, the upper overlapping flange above the front grille 2 and the license plate 24 are required to overlap on the upper guard body 3; such a design method can increase the contact area between the upper guard body 3 and the front grille 2, and better ensure the stability of the connection when the two are overlapped with each other.

[0085] Furthermore, in the present invention, the grille body 201 includes a grille frame plate, and the grille frame plate is provided with a ventilation cavity 202; it is convenient for subsequent ventilation operations, convenient for air intake operations on the front cabin of the entire vehicle; it is convenient for air cooling of the front cabin area, and at the same time can reduce the wind resistance of the vehicle.

[0086] In addition, in the present invention, a decorative rib 203 is provided in the ventilation cavity 202; the decorative rib 203 serves not only an aesthetic purpose but also a supporting purpose, so as to ensure the structural strength of the front grille 2; specifically, in the present invention, the decorative rib 203 includes two spaced-apart lateral plates, and the two lateral plates are connected by a guide arc plate away from the side of the vehicle body; such a setting can ensure the strength of the decorative rib 203 while reducing the wind resistance formed by the decorative rib 203 by setting the guide arc plate.

[0087] Furthermore, a limiting mechanism is provided between the upper protection body 3 and the front grille 2 in the present invention, and the limiting mechanism plays a good role in position limitation, thereby preventing the upper protection body 3 and the front grille 2 from shaking along the Y direction during subsequent use; specifically, the limiting mechanism in the present invention includes a plurality of limiting components, each of which includes a limiting protrusion 271 arranged on the upper protection body 3 and a limiting groove 27 arranged on the front grille 2; during subsequent use, the upper protection body 3 is inserted into the limiting groove 27 of the front grille 2 through the limiting protrusion 271, thereby preventing the front grille 2 and the upper protection body 3 from shaking.

[0088] In addition, in step 3 of the present invention, the front grille 2 is required to be pressed and assembled from the side of the upper protection body 3 away from the vehicle body to the side close to the vehicle body; such an arrangement can avoid installation interference between the front grille 2 and the upper protection body 3.

[0089] Furthermore, in the present invention, a camera support plate 4 is provided on the upper protection body 3. The basic function of the camera support plate 4 is to be used for the installation and fixation of the front camera. In the present invention, the camera support plate 4 is required to be clamped on the upper protection body 3, and after the front grille 2 is overlapped on the upper protection body 3, it is also clamped with the camera support plate 4.

[0092] Furthermore, in the present invention, the outer trim 6 includes a middle trim 61, and the two ends of the middle trim 61 are respectively overlapped with an end trim 62, and the end trim 62 is pressed against the grille positioning end plate 21 on the grille body 201; the segmented outer trim 6 structure facilitates the production of the outer trim 6 structure. In the present invention, the end trim 62 is overlapped on the middle trim 61. During actual connection, the middle trim 61 is installed first, and then the end trim 62 is installed; reducing the mutual interference problem during the installation of the middle trim 61 and the end trim 62.

[0093] In addition, in the present invention, during assembly, the middle trim 61 is pre-installed first, and after the middle trim 61 is installed, an end trim 62 is overlapped on both ends thereof; such a setting can realize the extrusion and fixation of the ends of the middle trim 61 through the end trim 62, thereby ensuring the stability of the middle trim 61 being clamped on the front grille 2 and reducing the risk of the middle trim 61 falling off.

[0094] Obviously, the specific implementation of the present invention is not limited to the above-mentioned methods. As long as various non-substantial improvements are made using the method concept and technical solution of the present invention, they are all within the protection scope of the present invention.
