AI Technical Summary
The existing front-end framework has limited adjustability, resulting in a large workload for adjusting gaps and surface differences in the later stages, making it difficult to meet design requirements.
By setting four fixed points on the front frame and installing L-shaped or Z-shaped fixed brackets, which are then bolted to the front side panel and longitudinal beam of the engine compartment, three-way adjustment is achieved, absorbing body tolerances and improving installation consistency.
It enables three-way adjustment of the front-end framework, improves installation accuracy and consistency, reduces the workload of later adjustments, lowers costs, and simplifies operation.

Abstract
Description
Technical Field
[0001] This utility model relates to the field of automotive parts, specifically to a fixed structure with an adjustable front frame. Background Technology
[0002] The front-end frame serves as a platform for mounting and supporting multiple modules in the front of the engine compartment. It is also a crucial component of the vehicle's overall structure and mechanical performance, and its application in vehicles is becoming increasingly widespread. Generally, the front-end frame is constructed from a metal / plastic hybrid material to securely mount components such as the engine compartment lock, radiator, condenser, headlights, bumper, and other parts. The installation precision requirements for the front-end frame are relatively high, directly impacting the adjustment of clearances in high-appearance areas such as the front bumper, headlights, and hood. Insufficient adjustment range of the front-end frame affects the clearances between the headlights, hood, and front bumper. Current technology uses through-holes to fix the front-end frame to the front side panels and longitudinal beams of the engine compartment, with adjustment limited to the Y / Z directions and a limited adjustment range, typically ±1mm. This results in a large workload for later adjustments to clearances, making it difficult to meet design requirements. Utility Model Content
[0003] This utility model addresses the above-mentioned problems by providing an adjustable fixed structure for the front-end framework, which effectively increases the adjustability of the front-end framework. The specific technical solution is as follows:
[0004] An adjustable fixing structure for a front frame includes a front frame and a front frame fixing bracket. Four fixing points are provided on the front frame, two on the side and two on the bottom. The front frame fixing bracket is installed on the fixing points. The front frame fixing bracket has two vertical fixing surfaces, and at least three fixing holes are provided on each vertical fixing surface. The fixing holes are fixed to the fixing points by bolts.
[0005] Furthermore, at least one fixing hole of the two front frame fixing brackets on the side is fixed to the front side panel of the cabin by bolts.
[0006] Furthermore, at least one fixing hole of the two front frame fixing brackets at the bottom is fixed to the longitudinal beam by bolts.
[0007] Furthermore, the front frame fixing bracket is kept in position relative to the fender by means of a fixture, and after adjustment, at least one of the front frame fixing brackets is fixed by bolts.
[0008] Furthermore, the front frame fixing bracket is set to L-shaped or Z-shaped, and the gap in the X / Y or X / Z direction is adjusted.
[0009] This invention differs from existing fixing methods by using an adapter bracket to achieve three-way adjustment of the vehicle body tolerances and the front frame position. The structure, through the adapter bracket, absorbs vehicle body tolerances, ensuring accurate relative positioning of the front frame and high installation consistency, thus avoiding the need for subsequent readjustment of gaps and surface differences. It can be achieved by adding a few small reinforcing parts and fasteners, offering advantages such as low cost, simple implementation, and good results. Attached Figure Description

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0016] An adjustable fixing structure for the front frame includes a front frame 1 and front frame fixing brackets 2 or 3. Four fixing points are provided on the front frame: two on the sides and two on the bottom. Front frame fixing brackets are installed at the fixing points, each bracket having two vertical fixing surfaces. Each vertical fixing surface has at least three fixing holes, which are bolted to the fixing points. At least one fixing hole of the two side front frame fixing brackets is bolted to the front side panel 4 of the cabin; in this embodiment, two fixing holes are used. At least one fixing hole of the two bottom front frame fixing brackets is bolted to a longitudinal beam 5; in this embodiment, two fixing holes are used.
[0017] Finally, using the fixture, maintain the position of the front frame mounting bracket relative to the fender. After adjustment, at least one of the front frame mounting brackets is secured with bolts. The front frame mounting bracket is configured as an L-type or Z-type, such as... Figure 2 and3 As shown, adjust the clearance in the X / Y or X / Z directions. Using the structure of this embodiment, the vehicle body tolerances are absorbed through the adapter bracket, ensuring accurate relative positioning of the front frame, high consistency in front frame installation, and avoiding the need for subsequent readjustment of clearance differences.
[0018] The preferred embodiments of this patent have been described in detail above. However, this patent is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of this patent.
