Description

Front end module device capable of adjusting front edge gap of hood and engine room assembly

Technical Field

The application relates to the technical field of automobile design, in particular to a front end module device capable of adjusting a front edge gap of a hood and a cabin assembly.

Background

With the progress of the times, the design requirements of automobile safety are gradually improved, and the requirements of pedestrian protection safety regulations and evaluation regulations at home and abroad become more and more strict. In order to ensure that the energy absorption effect of the front end of the vehicle to a pedestrian femoral region is improved when the front end of the vehicle collides with a pedestrian under the requirement of new-period pedestrian protection evaluation regulations, more and more new vehicle types move the front edge parting position of the hood backwards as much as possible (the front edge length of the hood is shortened, namely, a mode of 'facing the sky' is adopted, as shown in figure 1) during design, and therefore the fit clearance of the front edge of the hood is exposed in a vehicle appearance sensitive region. Therefore, the quality assurance of the front edge clearance of the hood in the production, use and after-sale maintenance links of the vehicle type becomes important.

The existing vehicle front end module device has the core functions of only providing an installation fixing interface for each component at the front end of the vehicle and ensuring the system internal clearance surface difference when the vehicle front end appearance components (generally comprising a front bumper, a front grille, a front combination lamp, a front position lamp, a front logo, a front decorative plate and the like) are assembled and taken off line. For the fit clearance between the front-end appearance assembly and the external interface piece, the appearance quality of a new vehicle during the offline process must be guaranteed by means of multiple large positioning tools in the assembling process. In addition, in order to guarantee the positioning utility of the positioning tool, the fastening mounting holes of the front-end components of the vehicle generally adopt a via hole design (otherwise, under the premise of normal tolerance deformation of the components, the fasteners cannot smoothly pass through the mounting holes), all the via hole designs cannot completely guarantee the position stability under the durable use working condition of the vehicle, and when the related parts of all the fastening points generate accumulated displacement, the fit clearance at the front edge of the hood is deteriorated.

Meanwhile, the assembly positioning tool for the front-end components of the vehicle is generally complex in structure, high in use difficulty and high in cost, so that the assembly positioning tool is generally only suitable for being used on a large-scale assembly production line of the vehicle. And in the quality repair, durable debugging and after-sale maintenance of the vehicle in the market accident after the vehicle is off line, if the condition of poor clearance fit of the front edge of the hood occurs, the positioning tool cannot be called, so that the conventional effective recovery means is basically absent.

Therefore, those skilled in the art are in need of designing a new technical solution to replace the large positioning tool and optimize the front edge clearance of the hood.

When the front edge gap 100 of the hood is abnormal, the self-locking displacement regulator 11 is regulated to change the front-back distance of the upper left end and the upper right end of the front end frame 1 relative to the lower vehicle body welding assembly 5.

Specifically, the front end frame 1 provides a mounting interface for each component, and front appearance components (including a front bumper, a front grille, a front combination lamp, a front position lamp, a front logo, a front decorative plate, etc.) are directly or indirectly fixed on the front end frame 1. A hood front edge gap 100 is formed between the front trim and the hood, and the position of the hood with respect to the lower body welding assembly 5 is always kept constant while the front trim is varied with the front-rear position variation of the front end frame 1. When the front edge gap 100 of the hood is abnormal, the self-locking displacement regulator 11 is adjusted to change the front and back positions of the front end frame 1, so that the front edge gap 100 of the hood can be continuously adjusted.

Specifically, the continuously adjustable range of the hood leading edge gap 100 can reach ± 5mm, which can solve most of the problems of the hood leading edge gap anomaly.

Preferably, the self-locking displacement adjuster 11 is injection molded integrally with the front end frame 1.

In one embodiment, the self-locking displacement adjuster 11 comprises a double-head screw cylinder 111, a circular toothed disc 112 and an adjusting body 113, wherein the double-head screw cylinder 111 is horizontally arranged in the front-back direction, the rear end of the double-head screw cylinder is a screw 1111, and the front end of the double-head screw cylinder is a screw 1113.
