Description

Technical Field

[0001] The utility model relates to the field of the automotive industry, particularly to the field of plastic part assembly technology, and specifically refers to a plastic elastic structure capable of absorbing tolerances. Background Art

[0002] For existing plastic part snap-fit structures, some use the inclination angle of the mating structure to absorb a certain range of tolerances, achieving the purpose by the snap-fit part staying at different positions on the slope, and some use the material characteristics of themselves to absorb a certain range of tolerances. The material itself has a certain toughness and can absorb a small range of tolerances, but the effect is not obvious. In addition, due to slight deformation during the injection molding process of plastic parts, there is a certain deviation between the actual size of the injection-molded parts and the theoretical value. In terms of appearance products, especially the fit between two plastic parts, if there is a fit gap, it will give a cheap feeling in terms of perception and directly affect the quality of the entire product.

[0003] In view of this, in combination with the actual application field of the automotive door handle of this product, it is necessary to design a structure that can effectively solve the problem of loose snap-fit of the handle cover and the handle body in a small range to solve the deficiencies of the existing technology. Summary of the Utility Model

[0004] The purpose of the utility model is to overcome the above-mentioned deficiencies in the existing technology and provide a plastic elastic structure capable of absorbing tolerances.

[0005] In order to achieve the above purpose, a plastic elastic structure capable of absorbing tolerances of the utility model is specifically as follows:

[0006] The plastic elastic structure capable of absorbing tolerances is mainly characterized in that the elastic structure includes:

[0007] An elastic structure provided on the handle body and a retaining wall structure provided on the handle cover. The elastic structure is in extrusion fit with the retaining wall structure so that the handle body and the handle cover are tightly snap-fitted.

[0008] Preferably, the elastic structure is a double elastic piece.

[0009] Preferably, a clearance value with a certain absorption amount is preset between the handle body and the handle cover at the beginning of assembly.

[0010] Preferably, when the elastic structure is in extrusion fit with the retaining wall structure, the retaining wall structure squeezes the double elastic pieces, so that the handle cover is pushed back to the mating position under the reaction force, so that the handle body and the handle cover are snap-fitted with zero clearance.

[0011] The utility model adopts the tolerance-absorbing plastic elastic structure, and the elastic design of the structure is used to absorb the gap tolerance between plastic parts, which effectively improves the product's fault tolerance level. In different environments, the adaptively adjustable structural characteristics can make the entire product more high-quality and robust. It can solve the problem of a small gap between the handle cover and the handle body, and prevent the handle cover from having a slight gap after being installed on the handle body, which may cause movement when touched by people. It has certain applicable value. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] In order to more clearly describe the technical content of the present invention, further description is given below in conjunction with specific embodiments.

[0025] Before describing in detail the embodiments according to the present invention, it should be noted that, hereinafter, the terms "comprises", "comprising" or any other variations are intended to cover non-exclusive inclusion, whereby a process, method, article or apparatus comprising a series of elements includes not only these elements, but also other elements not explicitly listed or inherent to such process, method, article or apparatus.

[0026] Please refer to Figures 1 to 4 As shown, the absorbable tolerance plastic elastic structure of the present utility model, wherein the elastic structure includes:

[0027] An elastic structure 1-1 provided on the handle body 1 and a retaining wall structure 2-1 provided on the handle cover 2. The elastic structure 1-1 is in extrusion fit with the retaining wall structure 2-1 so that the handle body 1 and the handle cover 2 are tightly engaged.

[0028] As a preferred embodiment of the present utility model, the elastic structure 1-1 is a double elastic sheet.

[0029] As a preferred embodiment of the present utility model, when the handle body 1 and the handle cover 2 are initially assembled, a clearance value with a certain absorption amount is preset.

[0030] As a preferred embodiment of the present utility model, when the elastic structure 1-1 is in extrusion fit with the retaining wall structure 2-1, the retaining wall structure 2-1 squeezes the double elastic sheet, so that the handle cover 2 is pushed back to the mating position 3 under the reaction force, so that the handle body 1 and the handle cover 2 are in zero-clearance engagement.

[0031] In actual application, the absorbable tolerance plastic elastic structure of this technical solution presets and absorbs a certain amount of clearance value at the beginning of the cooperation between the handle cover 2 and the handle body 1. When the handle cover 2 is pre-assembled, its retaining wall structure 2-1 will squeeze the double elastic sheet 1-1 on the handle body 1. The double elastic sheet 1-1 has a certain toughness and elasticity. Under the action of the reaction force, the handle cover 2 will be pushed back to the mating position. Under the action of this dynamic stress, the cooperation between the handle cover 2 and the handle body 1 will become tighter and more secure, so that the two products are in a zero-clearance state when they are combined.

[0032] In a specific embodiment of the present invention, the handle cover 2 as shown in Figure 2 is slidably snapped onto the handle body 1 as shown in Figure 1 from right to left. After the two are assembled, it is as shown in Figure 3 ; Through the perspective view Figure 4 it can be observed that the mating position of the double elastic sheet of the elastic structure 1-1 and the retaining wall of the handle cover 2 is as shown in Figure 4 ; Figure 4 The double elastic sheet and the retaining wall are in an interference state in

[0033] The utility model adopts the tolerance-absorbing plastic elastic structure, and the elastic design of the structure is used to absorb the gap tolerance between plastic parts, which effectively improves the product's fault tolerance level. In different environments, the adaptively adjustable structural characteristics can make the entire product more high-quality and robust. It can solve the problem of a small gap between the handle cover and the handle body, and prevent the handle cover from having a slight gap after being installed on the handle body, which may cause movement when touched by people. It has certain applicable value.

[0034] In this specification, the utility model has been described with reference to its specific embodiments. However, it is obvious that various modifications and changes can be made without departing from the spirit and scope of the utility model. Therefore, the description and drawings should be regarded as illustrative rather than restrictive.
