Description

Technical Field

[0001] The utility model relates to the technical field of the structural design of mechanical assembly parts, and particularly relates to a shrapnel piece. Background Art

[0002] With the high-quality and high-quality rapid development of China's automobile design and manufacturing industry, the appearance and components of automobiles are gradually moving towards high-end. For example, the automobile door handle has evolved from a common type protruding from the door plane with high wind resistance to a hidden type flush with the door plane, making the overall appearance of the vehicle more beautiful and high-end. However, the installation of the hidden handle must meet the requirements of the handle being flush with the door plane and the equal gaps at the edges of the handle. To solve this problem, a tolerance adjuster connected by multiple bolts must be used to meet the requirements of the plane angle and position adjustment of the hidden door handle. In this special tolerance adjuster assembly, the design of a key elastic component is involved. The technical requirements for this elastic component are as follows: 1. The initial pressing force is small to avoid forming a large initial frictional resistance to the radially movable adjusting part, so as to facilitate the adjustment of the radially movable adjusting part; 2. In addition, it is difficult to accurately control the spring compression amount during installation. Therefore, it is required that within a certain compression amount range of this elastic component, the spring pressing force is not sensitive to the compression amount; 3. After the spring is fully compacted, its elastic performance can be guaranteed not to degenerate due to long-term metal aging for a long time.

[0003] Obviously, the above technical requirements of the spring are difficult to be met by ordinary helical springs and ordinary disc springs. Therefore, it is necessary to design a new elastic structure that meets the above requirements. Summary of the Utility Model

[0004] Based on the above description, the utility model provides a shrapnel piece to solve the technical problem that the existing springs in the tolerance adjuster cannot meet the requirements of a small initial pressing force and the spring being insensitive to the compression amount within a certain compression amount range.

[0005] The technical solution of the utility model to solve the above technical problem is as follows:

[0006] A shrapnel piece includes a support part and at least three elastic legs. The outer contour of the support part is circular. The elastic legs are evenly spaced around the outer circumference of the support part. The extending direction of the elastic legs is consistent with the radial direction of the support part in the horizontal direction and consistent with the axial direction of the support part in the vertical direction, so that the support part and several elastic legs form a horn-shaped structure. The connection part between the elastic legs and the support part forms a bending part protruding from the surface of the support part, and the protruding direction of the bending part is opposite to the extending direction of the elastic legs.

[0007] Compared with the prior art, the technical solution of the present application has the following beneficial technical effects:

[0008] The shrapnel of the present application is provided with a plurality of elastic legs on the outside of the support part, so that the support part and the elastic legs form a horn-shaped structure. The elastic force is provided by the deformation of the elastic legs relative to the support part. Since the connection part between the elastic legs and the support part forms a bending part protruding from the surface of the support part, and the protruding direction of the bending part is opposite to the extending direction of the elastic legs, the internal stress at the connection part between the elastic legs and the support part is effectively reduced, and the anti-bending performance is improved. When the elastic legs are in the initial deformation period, a large pressing force will not be generated, which is convenient for the convenient adjustment of other components in the preloading situation. When it is perfectly flattened, the deformation of the elastic legs relative to the support part increases, and the elastic force formed by the elastic legs under the action of the bending part gradually increases, ensuring the pressing of the associated components and perfectly meeting the design requirements.

[0009] On the basis of the above technical solutions, the present utility model can be further improved as follows.

[0010] Further, a flanging is formed at one end of the elastic leg away from the support part, and the folding direction of the flanging faces the support part.

[0011] Further, the side of the flanging away from the support part is an arc surface or a smooth curved surface.

[0012] Further, a through hole is formed in the middle of the support part.

[0013] Further, the shrapnel is made of stainless steel.

[0014] Further, the thickness of the shrapnel is 0.15 - 0.3 mm.

[0015] Further, the included angle corresponding to each elastic leg on the outer periphery of the support part is not greater than 45°. Description of the Drawings

Embodiments of the present application are given in the drawings. However, the present application can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of the present application more thorough and comprehensive.

[0019] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terms used in the description of this application herein are for the purpose of describing specific embodiments only and are not intended to limit this application.

[0020] It can be understood that spatial relationship terms such as "under", "below", "lower", "beneath", "above", "upper", etc. can be used herein to describe the relationship of one element or feature shown in the figure with other elements or features. It should be understood that in addition to the orientation shown in the figure, spatial relationship terms also include different orientations of the device during use and operation.

Therefore, the exemplary terms "under" and "below" can include both the upper and lower orientations. In addition, the device can also include other orientations (such as rotating 90 degrees or other orientations), and the spatial descriptive terms used herein are accordingly interpreted.

[0021] It should be noted that when an element is considered to be "connected" to another element, it can be directly connected to the other element or connected to the other element through an intermediate element. For "connection" in the following embodiments, if there is an electrical signal or data transfer between the connected circuits, modules, units, etc., it should be understood as "electrically connected", "communicatively connected", etc.

[0022] As used herein, the singular forms "a", "an" and "the" may also include the plural forms unless the context clearly dictates otherwise. It should also be understood that the terms "comprises / include" or "has" etc. specify the presence of the stated features, wholes, steps, operations, components, parts or combinations thereof, but do not preclude the possibility of the presence or addition of one or more other features, wholes, steps, operations, components, parts or combinations thereof.

[0023] As Figure 1 As shown, an embodiment of the present application provides a shrapnel, which includes a support portion 10 and at least three elastic legs 20. The outer contour of the support portion 10 is circular. The elastic legs 20 are evenly spaced around the outer periphery of the support portion 10. The extending direction of the elastic legs 20 is radially consistent with the support portion 10 in the transverse direction and axially consistent with the support portion 10 in the longitudinal direction, so that the support portion 10 and several of the elastic legs 20 form a horn-shaped structure. A bending portion 30 protruding from the surface of the support portion 10 is formed at the connection of the elastic leg 20 and the support portion 10. The protruding direction of the bending portion 30 is opposite to the extending direction of the elastic leg 20.

[0024] For the shrapnel provided in this application, a plurality of elastic legs 20 are arranged outside the supporting part 10, so that the supporting part 10 and the elastic legs 20 form a horn-shaped structure. The elastic force is provided by the deformation of the elastic legs 20 relative to the supporting part 10. Since a bending part 30 protruding from the surface of the supporting part 10 is formed at the connection between the elastic legs 20 and the supporting part 10, the protruding direction of the bending part 30 is opposite to the extending direction of the elastic legs 20, thereby effectively reducing the internal stress at the connection between the elastic legs 20 and the supporting part 10, improving the anti-bending performance, so that the elastic legs 20 will not generate a large pressing force during the initial deformation period, facilitating the convenient adjustment of other components in the preloading situation. When it is perfectly pressed, the deformation of the elastic legs 20 relative to the supporting part 10 increases, and the elastic force formed by the elastic legs 20 under the action of the bending part 30 gradually becomes larger, ensuring the pressing of the associated components and perfectly meeting the design requirements.

[0025] In order to facilitate the convenient adjustment of the component pressed by the elastic legs 20 during preloading and reduce the adjustment resistance, a flanging 40 is formed at one end of the elastic legs 20 away from the supporting part 10, and the folding direction of the flanging 40 faces the supporting part.

[0026] Preferably, the side of the flanging 40 away from the supporting part 10 is an arc surface or a smooth curved surface.

[0027] As Figure 2 shown, in some applicable working conditions, the supporting part 10 needs to generate deformation through the relative action of bolts and nuts. In order to facilitate the installation of the bolts, a through hole 10a is formed in the middle of the supporting part 10.

[0028] In a preferred embodiment of this application, the shrapnel is made of stainless steel and has a thickness of 0.15 - 0.3 mm.

[0029] In order to ensure that the elastic legs 20 do not generate a large pre-tightening pressure during the initial deformation, the included angle corresponding to each elastic leg 20 on the outer periphery of the supporting part 10 is not greater than 45°.

[0030] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention shall be included in the protection scope of the present invention.
