[0001] This invention relates to spring components. Background Technology

[0002] A spring component is known, which is disposed between a first pressed body and a second pressed body to apply pressure to one or both of them (see, for example, Patent Document 1). The spring component described in Patent Document 1 has a plurality of spring tongues formed by bending and cutting a portion of a plate-shaped component to form a raised shape, the spring tongues being pressed against a pressed body and applying a load to it.

[0003] Patent document 1: Japanese Patent Application Publication No. 2005-302729. Summary of the Invention

[0004] However, depending on the application, miniaturization of spring components is sometimes required. However, if the number of spring tongues is reduced in order to achieve miniaturization, the load applied by the spring components to the pressed body will be reduced.

[0005] The present invention was made in view of the above-mentioned problems, and its object is to provide a spring component that can suppress the reduction of load applied to the pressed body and achieve miniaturization.

[0006] To solve the above problems and achieve the objective, the spring component of the present invention is disposed between two pressed bodies for applying pressure to the pressed bodies. The spring component includes: a support portion; a plurality of spring portions, which are partially curved into an arc shape; and a plurality of first connecting portions, which extend along a first direction for connecting the support portion and the spring portions. The support portion and the plurality of first connecting portions are located on the same plane parallel to the first direction. Among the plurality of spring portions, the closest spring portions are arranged to partially overlap each other in the first direction and in a second direction, respectively. The second direction is orthogonal to the first direction on the plane.

[0007] Furthermore, the spring component of the present invention, in the above-described invention, further includes: a second connecting portion for connecting adjacent spring portions in the first direction to each other.

[0008] Furthermore, the spring component of the present invention, in the above invention, has: a base portion connected to the support portion, the first connecting portion or the second connecting portion; a first curved portion extending upward relative to the plane from one end of the base portion in the first direction; and a first end portion extending from the end of the first curved portion on the side opposite to the base portion in a curved shape opposite to the first curved portion.

[0009] Furthermore, the spring component of the present invention, in the above invention, further comprises: a second curved portion, which extends from the end of the base on the side opposite to the first curved portion side, relative to the plane toward the same side as the side on which the first curved portion is erected; and a second end portion, which extends from the end of the second curved portion on the side opposite to the base side in a curved shape opposite to the second curved portion.

[0010] Furthermore, in the spring component of the present invention, the length of the first curved portion in the first direction gradually decreases from the base toward the first end in the above-described invention.

[0011] Furthermore, the spring component of the present invention is such that, in the above invention, the length of the first curved portion in the first direction gradually decreases from the base toward the first end, and the length of the second curved portion in the first direction gradually decreases from the base toward the second end.

[0012] According to the present invention, the following effects are achieved: the load applied to the pressed body is reduced, while miniaturization is realized. Attached Figure Description

[0023] In the following description, the spring component will be described as an embodiment for carrying out the present invention (hereinafter referred to as "the embodiment"). However, the present invention is not limited to this embodiment. Furthermore, in the accompanying drawings, the same reference numerals are used to denote the same parts. It should also be noted that the drawings are schematic diagrams, and the thickness-to-width ratio, proportions, etc., of each component may differ from reality. Additionally, the drawings may include portions with different dimensions or proportions.

[0024] Implementation Figure 1 This is a top view showing the structure of a spring component according to an embodiment of the present invention. Figure 2 This is a perspective view showing the structure of a spring component according to one embodiment of the present invention. Figure 3 This is a simplified top view illustrating the structure of a spring component according to an embodiment of the present invention. The spring component 1 of this embodiment is disposed between a first pressed body and a second pressed body, applying pressure to both pressed bodies through elastic force. For example, in... Figure 1 In the example shown, the two pressed bodies are arranged in a direction orthogonal to the paper to sandwich the spring component 1 in the middle.

[0025] In the following figures, the X direction (second direction) and the Y direction (first direction) extend in the same plane and are orthogonal to each other. Furthermore, in the following description, the X direction may sometimes be defined as the extension direction (length direction) of the spring portion. Further, the direction orthogonal to the XY plane is defined as the Z direction.

[0026] Spring component 1 is formed using a flat spring steel made of metal, resin, or the like. For example, spring component 1 is formed by stamping the flat spring steel into the shape of spring component 1 and partially bending it.

[0027] The spring component 1 includes: a plurality of spring portions 2, a support portion 3, a plurality of first connecting portions 4 connecting the spring portions 2 to the support portion 3, and a plurality of second connecting portions 5 connecting the spring portions 2 to each other.

[0028] The spring portion 2 is a strip that is curved in an arc shape along its length. Specifically, the spring portion 2 has: a base 21; a first curved portion 22 that extends upward from one end of the base 21 in the X direction relative to the XY plane; a second curved portion 23 that extends upward from the end of the base 21 on the side opposite to the side of the first curved portion 22 relative to the XY plane towards the same side as the side on which the first curved portion 22 is erected; a first end portion 24 that extends from the end of the first curved portion 22 on the side opposite to the side of the base 21 in a curved shape opposite to that of the first curved portion 22; and a second end portion 25 that extends from the end of the second curved portion 23 on the side opposite to the side of the base 21 in a curved shape opposite to that of the second curved portion 23.

[0029] The width of the first curved portion 22 (here referring to the length in the Y direction) gradually decreases from the base 21 side to the first end 24 side.

[0030] The width of the second curved portion 23 gradually decreases from the base 21 side to the second end 25 side.

[0031] Furthermore, in this embodiment, each spring part 2 is described as having the same shape and size, but it may also have different shapes such as curved shape or size.

[0032] Additionally, for example, in the first bend 22 and the second bend 23, the "gradually decreasing width" structure also includes a portion of the structure extending with the same width. Specifically, the first bend 22 may include a portion extending with the same width as the base 21 or the first end 24 in the part connecting the base 21 or the first end 24, or a portion extending with the same width in the central part of the first bend 22 in the X direction.

[0033] The support portion 3 supports the spring portion 2, the first connecting portion 4, and the second connecting portion 5. In this embodiment, the support portion 3 is annular in the XY plane and houses the spring portion 2, the first connecting portion 4, and the second connecting portion 5 within it. The spring portion 2 is supported by the support portion 3 via the first connecting portion 4 and the second connecting portion 5. Figure 1 and Figure 2 In this design, the support portion 3 has a concave-convex shape corresponding to the outer edge shape of the spring portion 2, and its width is partially inconsistent, but it can also extend with the same width. Furthermore, the width referred to here is equivalent to the length in the XY plane in the direction orthogonal to the direction in which the support portion 3 extends. Additionally, "identical" means "identical," including manufacturing errors, etc. By having a concave-convex shape corresponding to the outer edge shape of the spring portion 2, the wall thickness of the support portion 3 is ensured, thereby improving the strength of the support portion 3.

[0034] In the XY plane, the base 21 and the support 3 are located on the same plane.

[0035] The first connecting portion 4 extends from the support portion 3 along the Y direction and is used to connect the support portion 3 and the base portion 21.

[0036] The second connecting portion 5 extends along the Y direction and is used to connect the bases 21 of adjacent spring portions 2 in the Y direction to each other.

[0037] That is, the base 21 is connected to the support 3 via the first connecting part 4, and is connected to the base 21 of another spring part 2 adjacent in the Y direction via the second connecting part 5.

[0038] Furthermore, each of the first connecting portions 4 includes a first connecting portion 4 of varying lengths depending on the distance between the connected objects. The same applies to the second connecting portion 5.

[0039] In this configuration, from a top-view perspective (Z direction) orthogonal to the XY plane, multiple spring portions 2 are staggered within the spring component 1. The two spring portions 2 closest to each other in the spring component 1 do not overlap when viewed from a top-view perspective orthogonal to the XY plane, but are positioned at points that partially overlap in both the X and Y directions. For example, in... Figure 3 In the example shown, the spring portion 201 located at the upper left and the nearest spring portion 202 (here, the spring portion 2 located at the lower right of spring portion 201) overlap in the X direction within the range Rx and in the Y direction within the range Ry. Thus, in the spring component 1, each spring portion 2 has the relationship described above with respect to the other nearest spring portion 2.

[0040] In a pressing unit comprising two pressing bodies (a first pressing body and a second pressing body) and a spring component 1, the spring component 1 is fixed between the first pressing body and the second pressing body (see [reference]). Figure 1 At this time, the first end 24 and the second end 25 of the spring part 2 are in contact with one pressed body, and the base 21, the support part 3, the first connecting part 4, and the second connecting part 5 of the spring part 2 are in contact with another pressed body. The spring component 1 applies a load to the first pressed body and the second pressed body.

[0041] In the above embodiment, the two spring portions 2 closest to each other in the spring component 1 are configured to partially overlap in the X and Y directions, thus suppressing the reduction in the number of spring portions 2 and reducing the arrangement area of ​​the spring portions 2. According to this embodiment, it is possible to suppress the reduction of the load applied to the pressed body and achieve miniaturization.

[0042] Furthermore, in the above embodiment, in the spring component 1, the two spring components 2 arranged side by side in the Y direction are connected by the second connecting part 5 without passing through the support part 3, thus enabling further miniaturization. In addition, it can increase the degree of freedom in the design of the spring components 2.

[0043] Furthermore, in the above embodiment, the spring part 2 in the spring member 1 is configured with a narrower front end shape whose width decreases from the base side to the end side. Therefore, the spring part 2 can be configured in the spring member 1 to reduce unnecessary space, and as a result, the spring member 1 can be further miniaturized.

[0044] Furthermore, in the above embodiment, it is also possible to configure a structure without the second connecting portion 5. Further, in the spring portion 2 where two first connecting portions 4 are connected to the base 21, it is also possible to configure a structure having only one of the first connecting portions 4.

[0045] Variation Example 1 Next, refer to Figure 4 A variation of this embodiment, Example 1, will be described. Figure 4 This is a diagram illustrating the structure of the spring component in Modified Example 1 of an embodiment of the present invention. Furthermore, with...

[0065] Furthermore, in a top-view perspective viewed from a direction orthogonal to the XY plane (Z direction), spring portions 2 and 2A are staggered. Similar to the embodiment, in spring component 1C, the two spring portions closest to each other do not overlap in a top-view perspective viewed from a direction orthogonal to the XY plane, but are positioned at points that partially overlap in the X and Y directions, respectively.

Compared to the structure of spring component 1 in the embodiment, this variation 7 is configured to have five spring sections. Hereinafter, the same symbols will be used to denote structural elements as in the embodiment, and descriptions will be omitted.

[0095] The spring component 1G of this variation 7 includes: four spring portions 2A, one spring portion 2D, a support portion 3, three first connecting portions 4 that connect the spring portions 2A and 2D to the support portion 3 respectively, and two second connecting portions 5 that connect the spring portions 2A to each other. In this variation 7, the support portion 3 is in the shape of a straight line extending in the X direction.

[0096] In this case, the spring part 2A has the same structural elements as in the modified example 3, and in the XY plane, the base part 21A and the support part 3 are located on the same plane.

[0097] The spring portion 2D is a strip-shaped section curved in an arc along its length. Specifically, the spring portion 2D has: a base 21D; a first curved portion 22D extending upward from one end of the base 21D in the X direction; a second curved portion 23D extending upward from the end of the base 21D opposite to the side of the first curved portion 22D; a first end portion 24D extending from the end of the first curved portion 22D opposite to the side of the base 21D with a curved shape opposite to that of the first curved portion 22D; and a second end portion 25D extending from the end of the second curved portion 23D opposite to the side of the base 21D with a curved shape opposite to that of the second curved portion 23D. In the XY plane, the base 21D and the support portion 3 are located in the same plane.

[0098] The first curved portion 22D, the second curved portion 23D, the first end portion 24D, and the second end portion 25D have a width smaller than that of the base portion 21D. That is, the spring portion 2D has a shape in which the width changes in stages along the X direction.

[0099] In addition, each first connecting part 4 extends from both ends of the support part 3 or from the center of the length direction (X direction) along the Y direction, and connects the support part 3 to the spring part 2A (base 21A) or the spring part 2D (base 21D).

[0100] Each second connecting portion 5 extends along the Y direction and is used to connect the base 21A of adjacent spring portions 2A in the Y direction to each other.

[0101] Furthermore, in a top-view perspective viewed from a direction orthogonal to the XY plane (Z direction), spring portions 2A and 2D are staggered. Similar to the embodiment, in spring component 1G, the two spring portions closest to each other do not overlap in a top-view perspective viewed from a direction orthogonal to the XY plane, but are positioned at points that partially overlap in the X and Y directions, respectively.

[0102] In the above-described Modification 7, similar to the embodiment, the spring parts in the spring member 1G are arranged such that they partially overlap each other in the X and Y directions, thus suppressing the reduction in the number of spring parts and reducing the arrangement area of ​​the spring parts. According to this Modification 7, it is possible to suppress the reduction of the load applied to the pressed body and achieve miniaturization.

[0103] Thus, the present invention may include various embodiments not described herein, and various design changes may be made without departing from the technical concept defined by the scope of the claims.

[0104] Furthermore, in variations 1 to 7, the support portion 3 may be provided on both sides of the spring portion in the Y direction and connected to the spring portion via the first connecting portion 4, or it may be in the form of a frame surrounding the spring portion, as in the embodiment. When the support portion 3 is in the form of a frame, in each structure, the first connecting portion 4 may be added to connect the first connecting portion 4 to both sides of the spring portion in the Y direction.

[0105] Furthermore, in the embodiments and variations 1 to 7, examples of the first connecting portion 4 or the second connecting portion 5 extending along the Y direction were described, but it is also possible to configure it to extend obliquely relative to the Y direction.

[0106] Industrial applicability As described above, the spring component of the present invention is adapted to suppress the reduction of the load applied to the pressed body and to achieve miniaturization.
