DETAILED DESCRIPTION

[0020] The present invention is described in detail below with reference to the accompanying drawings and embodiments.

[0021] like Figure 1-Figure 7As shown, the present invention provides an integral front mounting structure of a pickup truck, including a headlight 1, a headlight decoration 3 and a front grille assembly 2, wherein the headlight 1 includes a headlight side limit bracket 4, a limit column 1 5, a cantilever hook 6 and a limit column 2 7, wherein the headlight side limit bracket 4 and the cantilever hook 6 are arranged on the inner side of the headlight 1 to be snap-fitted with the side of the front grille assembly 2 to limit the Y-direction mounting space of the front grille assembly 2; the limit column 1 5 is arranged on the upper part of the headlight 1 to be matched with the opening of the front grille assembly 2 to limit the X-direction mounting size of the front grille assembly 2; the cantilever hook 6 and the limit column 2 7 are arranged at the bottom of the headlight 1, and the limit column 2 7 controls the Z-direction mounting space of the headlight decoration 3.

[0022] The front grille assembly 2 includes a grille upper fixing hole 8, a grille opening 9, a grille side bayonet structure 10, a grille limiting rib 11 and a grille bottom bayonet structure 12. The grille upper fixing hole 8 has an open hole diameter. The bayonet structure at the side and bottom of the front grille assembly 2 where it fits with the front headlights, the cantilever hook structure of the headlights is interlocked and limited, and the protruding limiting rib structure of the front grille assembly 2 is used to constrain the matching clearance with the headlight decorative parts.

[0023] Positioning openings for the front headlight decoration 3 are provided on both sides of the front grille assembly 2 to preferentially ensure the matching clearance between the front headlight decoration and the front grille assembly 2 .

[0024] A Y-shaped long hole is provided in the middle of the headlight 1 to fit the snap-fit ​​structure of the headlight decoration.

[0025] The headlight 1 and the headlight decoration 3 are matched with a face difference structure 16 in the X direction. The face difference means that the headlight is higher than the headlight decoration by a certain value in shape. This structure can block the gap viewing angle here to weaken the visual sense of the gap here.

[0026] The headlight decoration part 3 is fixed by snap connection, including a positioning buckle 13 and a buckle 14, and its positioning position can also take into account the guiding function; the long hole adapted to the headlight 1 is opened in the Y direction to absorb the front assembly tolerance.

[0027] The installation process of the present invention is as follows:

[0028] First install the headlight 1 in place, and then start assembling the front grille assembly 2; install the long strip hole 17 on the upper part of the front grille assembly 2 to the headlight side limit bracket 4, the headlight side limit bracket 4 has both the X-direction limit function and can be used to carry the front grille assembly 2 during installation, which is convenient for workers to operate and install; the grille side bayonet structure 10 of the front grille assembly 2 cooperates with the headlight side limit bracket 4, and after being locked by the cantilever hook structure, the headlight side limit bracket 4 plays a role in limiting the installation space, and the bracket material has a certain elastic modulus, which promotes the adaptive adjustment of the Y-direction gap between the front grille assembly and the headlight, so that the gap here is adjusted to a relatively balanced range;

[0029] Then, the upper fixing hole 8 of the grille is connected to the body bolts, and the opening size of the fixing point here is opened to adapt to the adaptive adjustment of the gap of the front grille assembly;

[0030] Then hang the front grille assembly 2 on the second limiting column 7 at the bottom of the headlight, push the grille bottom snap-in structure 12 of the front grille assembly 2 in the X direction, and snap-lock the snap-in of the front grille assembly with the headlight cantilever hook 6;

[0031] Finally, the headlight decoration 3 is installed. The headlight decoration 3 is fixed by the buckle 14, and the bayonet structure 12 at the bottom of the grille is close to the grille side; the headlight decoration 3 is installed in the X direction, and the grille limiting rib 11, the grille opening 9, and the headlight long strip hole 15 on the front grille assembly are contacted in sequence to constrain its installation state;

[0032] After the front components are installed, combined with the design ideas defined by the overall front installation strategy, the headlight side limit bracket 4, the grille opening 9, and the grille limit rib 11 respectively limit the installation dimensions of the opponent parts, and the cumulative amount of the front overall assembly tolerance is placed on the outside of the headlight decorative part 2. The X-direction surface difference structure 16 between the headlight side and the front headlight decorative part 3 can weaken the gap here, thereby realizing effective adjustment of the front installation.

[0033] The limiting column 1 5 and the limiting column 2 7 on the headlight are used to constrain the installation space of the hand parts, which can forcibly limit the excessive accumulation of vehicle body tolerances and achieve effective installation of the front components.

[0034] The present invention adopts a new positioning strategy, which is based on the idea of ​​adaptive compensation. Through structural setting, the dimensional chain tolerance of the upstream assembly link is adaptively adjusted. By using reasonable positioning and limit structure design, the key factors of the identified dimensional chain are controlled, thereby achieving the effect of improving the assembly quality.

[0035] The above embodiments of the present invention are merely illustrative and not exclusive, and all modifications within the scope of the present invention or equivalent to the scope of the present invention are encompassed by the present invention.
