Background
The automobile glove box is a more interior decoration functional part used by a user in daily use, and the use experience of the automobile glove box directly influences the visual experience of the user on the automobile quality.
The opening time of the automobile glove box is an important user perception quality index, and for improving user experience, the opening stroke of the glove box is uniform and smooth, as shown in fig. 1, the glove box structure with the damper appears in the prior art, and the damper is arranged to enable the novel glove box structure with the damper to realize automatic opening of the outer cover of the glove box, so that the opening time is fixed, no opening noise exists at the tail end of the opening stroke, and the customer satisfaction is improved.
However, the existing automobile glove box with the damper still has the following problems:
1. because the corresponding theoretical guidance of the glove box opening time and the damper setting position is not available, and the material of a CNC (computer numerical control) sample piece is inconsistent with the definition, whether the glove box opening time meets the requirements cannot be determined in the structural design and CNC sample piece verification stages;
almost every project in an ET stage (Engineering Trial, Engineering debugging and design verification stage) needs to adjust the opening time of the glove box door, the adjustment of the opening time of the glove box door by each project costs about 8 thousands on average, and the mold repair period is 20 days; if a problem occurs, the target requirements can only be satisfied by modifying the damper arrangement position or replacing the damper. If the damper is modified, the damper cannot be generalized, so that the cost is increased, and meanwhile, the dampers are various and the mistake proofing cannot be realized; the position of the damper is adjusted in the ET stage, and the hand sleeve box body needs to be repaired, so that the cost and the period are increased; if the mould is repaired or the damper is adjusted, the requirement of the project cannot be met, yielding reception is required, and therefore the sensing quality of the glove box is reduced.
Aiming at the specific theoretical guidance of the assembly position and angle of the glove box damper, a reasonable design method of a glove box damping structure is provided in a paper 'a damping structure design of a glove box of an automobile' (Tokui, Happy, Hazard school, damping structure design of a glove box of an automobile [ J ]. Timber automobile, 2018(6):103 plus 107 ]), which is published by Wuling automobile GmbH, so that the glove box has good damping performance in the use process, can be smoothly opened within 2-3 seconds and has certain grade. The design idea of the device is mainly to obtain the structural characteristics of the existing glove box such as the gravity, the mass center, the inertia moment and the like, grasp the damping characteristics of the damper such as the relation of resistance along with the stretching speed and the stroke and obtain reasonable assembly position and angle through certain theoretical analysis. The content of the glove box structure with the damper is only a simple overview of the structure of the glove box with the damper, and on one hand, the content only relates to the content of the assembly position and angle calculation of the damper, and does not relate to the connection between a specific installation and debugging method and theoretical calculation; on the other hand, the algorithm consideration parameters are based on the mass distribution parameters such as the gravity and the mass center of the existing glove box, and the method of quantitatively connecting the opening time of the glove box with the setting position of the damper is not provided.
Therefore, a new method for installing and debugging a glove box damper is urgently needed by those skilled in the art, and the opening time of the glove box and the setting position of the damper are correspondingly associated, so as to solve the problem that the opening time of the glove box in the existing scheme is only determined by experience and cannot be adjusted according to requirements.
