Abstract
Description
Technical Field
[0001] The present application relates to the field of riveting technology, and in particular to a riveted structure. Background Art
[0002] The riveted structure is formed by riveting multiple components together. When the components are riveted together, they need to be accurately positioned relative to each other so that the positions of the components of the riveted structure can be accurate after riveting.
[0003] In the prior art, a jig is typically equipped with positioning posts, and each component of the riveted structure is provided with positioning holes. The posts pass through the holes to position the components. Because each positioning post and each positioning hole typically have machining errors, there is a positioning error between each component and the jig. These positioning errors accumulate, resulting in even greater relative positioning errors between the components.
[0004] In order to reduce the mutual positioning error, the requirements for the accuracy of the positioning columns on the jig and the positioning holes on the component are usually increased, which leads to an increase in the production cost of the jig and the component; it also leads to a decrease in the yield rate of the component, and ultimately increases the production cost of the riveted structure. Utility Model Content
[0005] The embodiments of the present application aim to provide a riveted structure, so as to at least reduce the production cost of the riveted structure.
[0006] In order to solve the above technical problems, the embodiments of the present application adopt the following technical solutions:
[0007] In a first aspect, embodiments of the present application provide a riveted structure comprising a first member and a second member. The first member is provided with a first protrusion. The second member is riveted to the first member, and the second member is provided with a first hole, the position of the first hole corresponding to the position of the first protrusion, and the first protrusion is at least partially located in the first hole.
[0008] In some embodiments, the number of the first protrusions and the number of the first holes are both multiple, and the number of the first holes is equal to the number of the first protrusions; each first protrusion corresponds to the position of one of the first holes, and each first protrusion is at least partially disposed in one of the first holes.
[0009] In some embodiments, the first protrusion is formed by stamping the first component.
[0010] In some embodiments, when viewed along the arrangement direction of the first member and the second member, the first protrusion is matched with the first hole.
[0011] In some embodiments, when viewed along the arrangement direction of the first member and the second member, the first protrusion and the first hole are both circular.
[0012] In some embodiments, the first component is provided with a second hole, and the second component is provided with a third hole, and the position of the third hole corresponds to the position of the second hole; the riveted structure also includes a rivet, which is passed through the second hole and the third hole to rivet the second component to the first component.
[0013] In some embodiments, the number of the second holes and the number of the third holes are both multiple, the number of the second holes is equal to the number of the third holes, and the position of each of the third holes corresponds to the position of a second hole; the number of the rivets is multiple, and each of the rivets is passed through a corresponding second hole and a corresponding third hole.
[0014] In some embodiments, when viewed along the arrangement direction of the first component and the second component, the third hole is matched with the second hole.
[0015] In some embodiments, the rivet includes a connecting portion, a first supporting portion and a second supporting portion, and the two ends of the connecting portion are respectively connected to the first supporting portion and the second supporting portion; the first supporting portion supports the side of the first component facing away from the second component; the second supporting portion supports the side of the second component facing away from the first component; when observed along the arrangement direction of the first component and the second component, the connecting portion is adapted to the second hole or the third hole.
[0016] In some embodiments, there are multiple second components, and the multiple second components are riveted to the first component.
[0017] The riveted structure of the embodiment of the present application directly positions the first component and the second component relative to each other by at least partially penetrating the first protrusion of the first component through the first hole of the second component, which is beneficial to reducing the precision requirements for the first component and the second component, improving the yield rate of the first component and the second component, and reducing the production cost of the riveted structure.

[0036] In addition, the technical features involved in different embodiments of the present application described below can be combined with each other as long as they do not conflict with each other.
[0037] See also Figure 1 and 2 , Figure 1 The figure shows a schematic diagram of the structure of a riveting structure 100 and a fixture 200 in the prior art. Figure 2 Shown Figure 1An exploded view of the riveted structure 100 and jig 200. The riveted structure 100 includes a first component 1, a second component 2, and a rivet 3. The first component 1 is provided with a fourth hole 13, and the second component 2 is provided with a fifth hole 23. The jig 200 is provided with a positioning post 201, which extends through the fourth hole 13 and the fifth hole 23 to position the first component 1 and the second component 2 relative to the jig 200.
[0038] It is understandable that due to machining errors between the positioning post 201, the fourth hole 13, and the fifth hole 23, a first positioning error occurs between the first component 1 and the first jig 200 when the first component 1 is positioned relative to the jig 200 via the fourth hole 13 and the positioning post 201. Furthermore, a second positioning error occurs between the second component 2 and the first jig 200 when the second component 2 is positioned relative to the jig 200 via the fifth hole 23 and the positioning post 201. The first and second positioning errors accumulate, resulting in a mutual positioning error between the first component 1 and the second component 2 that is greater than the first and second positioning errors.
[0039] To reduce mutual positioning errors, the accuracy requirements for the positioning posts 201, the fourth holes 13, and the fifth holes 23 are typically increased. However, this increases the production costs of the jig 200, the first component 1, and the second component 2. Furthermore, due to the increased accuracy requirements for the first component 1 and the second component 2, the yield rate of the first component 1 and the second component 2 decreases, ultimately increasing the production cost of the riveted structure 100.
[0040] To improve the above problems, the present invention provides a riveted structure 100. Figures 3 to 5 , Figure 3 FIG. 1 shows a schematic structural diagram of a riveted structure 100 according to an embodiment of the present application. Figure 4 Shown Figure 3 An exploded view of the riveted structure 100 is shown. Figure 5 Shown Figure 3 FIG2 is a partial cross-sectional view of a riveted structure 100. The riveted structure 100 includes a first component 1 and a second component 2, wherein the second component 2 is riveted to the first component 1.
[0041] For the first component 1 above, see Figures 3 to 5 The first member 1 may be in sheet form. The first member 1 is provided with a first protrusion 11, which is used to realize the mutual positioning between the first member 1 and the second member 2. For example, please continue to refer to Figures 3 to 5 The second component 2 is provided with a first hole 21 . The position of the first hole 21 corresponds to the position of the first protrusion 11 . The first protrusion 11 is at least partially provided in the first hole 21 .
[0042] The position of the first hole 21 corresponds to the position of the first protrusion 11, which means that when viewed along the direction in which the first component 1 and the second component 2 are arranged, the projection of the first protrusion 11 coincides with the projection of the first hole 21. In this way, the first protrusion 11 can be disposed in the first hole 21.
[0043] Since the first protrusion 11 is at least partially provided in the first hole 21, the first protrusion 11 cooperates with the first hole 21 to directly position the first component 1 and the second component 2 relative to each other, eliminating the indirect positioning of the first component 1 and the second component 2 relative to each other through the positioning column 201. The mutual positioning error between the first component 1 and the second component 2 depends on the processing error of the first hole 21 and the first protrusion 11, that is, compared with Figure 1 and Figure 2 The illustrated riveted structure 100 can reduce the relative positioning error between the first component 1 and the second component 2. This, in turn, helps reduce the precision requirements for the first component 1 and the second component 2, improve the yield rate of the first component 1 and the second component 2, and reduce the production cost of the riveted structure 100.
[0044] In some embodiments, see Figures 3 to 5 , the number of the first protrusions 11 and the first holes 21 are both multiple, and the number of the first holes 21 is equal to the number of the first protrusions 11; each first protrusion 11 corresponds to the position of a first hole 21, and each first protrusion 11 is at least partially disposed in a first hole 21. It can be understood that, along the direction perpendicular to the arrangement of the first frame and the second member 2, the multiple first protrusions 11 are arranged at intervals, and the multiple first holes 21 are arranged at intervals. The positions of the first member 1 and the second member 2 relative to each other are positioned by the multiple first protrusions 11 and the first holes 21, which can improve the positioning accuracy and also limit the angle between the first member 1 and the second member 2. Optionally, the number of the first protrusions 11 and the first holes 21 are both two.
[0045] In some embodiments, the first protrusion 11 is stamped and formed on the first component 1. That is, the first protrusion 11 is directly formed on the first component 1, and there is no need to connect the first protrusion 11 to the body of the first component 1 through welding, bonding, or other steps. This helps reduce the processing cost of the first component 1 and helps improve the connection strength between the first protrusion 11 and the body of the first component 1.
[0046] In some embodiments, see Figures 3 to 5, observed along the arrangement direction of the first component 1 and the second component 2, the first protrusion 11 is adapted to the first hole 21. The first protrusion 11 is adapted to the first hole 21, which means that the first protrusion 11 can be inserted into the first hole 21, and under the restriction of the first hole 21, the first protrusion 11 cannot move relative to the second component 2 along the direction perpendicular to the opening of the first hole 21, that is, the first protrusion 11 can only move relative to the second component 2 along the opening direction of the first hole 21, or the first protrusion 11 can also rotate within the first hole 21 around the opening direction of the first hole 21. For example, please refer to Figure 3 and Figure 4 , observed along the arrangement direction of the first component 1 and the second component 2, the shape of the first protrusion 11 is the same as the shape of the first hole 21, and the size of the first protrusion 11 is the same as the size of the first hole 21, so that the first protrusion 11 is just inserted into the first hole 21.
[0047] In a specific embodiment, see Figure 3 and Figure 4 Observing along the arrangement direction of the first member 1 and the second member 2, the first protrusion 11 and the first hole 21 are both circular. In this embodiment, the first protrusion 11 can rotate within the first hole 21 around the opening direction of the first hole 21. When there are multiple first protrusions 11, the multiple first protrusions 11 cooperate with the multiple first holes 21 to position the first member 1 and the second member 2 relative to each other and limit the angle between the first member 1 and the second member 2.
[0048] In some embodiments, see Figure 3 and Figure 4 , observed along the arrangement direction of the first component 1 and the second component 2, the first protrusion 11 is circular; the number of first holes 21 is two, one first hole 21 is adapted to the first protrusion, and the other first hole 21 extends along the arrangement direction of the two first holes 21. It can be understood that one first hole 21 is circular and the other is elongated. One first protrusion can rotate around the opening direction of the first hole 21 in the circular first hole 21, and the other first protrusion can slide along the extension direction of the elongated first hole 21 in the elongated first hole 21. Therefore, when there is a processing error in the spacing between the two first protrusions 11, the two first protrusions 11 can still be inserted into the two first holes 21 respectively, thereby improving the problem that some first protrusions 11 cannot be correctly inserted into the first hole 21 due to processing accuracy.
[0049] In some embodiments, the first component 1 and the second component 2 can be riveted by stamping. For example, the first protrusion 11 passes through the first hole 21, and the part of the first protrusion 11 passing through the first hole 21 is flattened by stamping to rivet the second component 2 to the first component 1 through the first protrusion 11.
[0050] In some embodiments, the first component 1 and the second component 2 are riveted together by rivets 3. For example, see Figure 3 and Figure 4 The first component 1 is provided with a second hole 12, and the second component 2 is provided with a third hole 22, and the position of the third hole 22 corresponds to the position of the second hole 12; the riveted structure 100 also includes a rivet 3, which is passed through the second hole 12 and the third hole 22 to rivet the second component 2 to the first component 1.
[0051] The position of the third hole 22 corresponds to the position of the second hole 12, which means that when viewed along the direction in which the first component 1 and the second component 2 are arranged, the projection of the third hole 22 at least partially overlaps with the projection of the second hole 12. In this way, the rivet 3 can pass through the second hole 12 and the third hole 22 at the same time.
[0052] Specifically, see Figure 5 The rivet 3 includes a connecting portion 31, a first abutting portion 32, and a second abutting portion 33. The two ends of the connecting portion 31 are connected to the first abutting portion 32 and the second abutting portion 33, respectively. The first abutting portion 32 abuts against the side of the first component 1 facing away from the second component 2, while the second abutting portion 33 abuts against the side of the second component 2 facing away from the first component 1. The first abutting portion 32 and the second abutting portion 33 cooperate to press the first component 1 and the second component 2 together, thereby achieving riveting of the second component 2 to the first component 1.
[0053] In some embodiments, see Figure 3 and Figure 4 The number of second holes 12 and third holes 22 is equal, and the position of each third hole 22 corresponds to the position of a second hole 12. The number of rivets 3 is multiple, and each rivet 3 is inserted into a corresponding second hole 12 and a corresponding third hole 22. The riveted connection between the first component 1 and the second component 2 is achieved by using multiple rivets 3, which can improve the riveting strength between the first component 1 and the second component 2. Optionally, the number of second holes 12 and the number of third holes 22 are both two, and the number of rivets 3 is two.
[0054] In some embodiments, see Figures 3 to 5 , viewed along the arrangement direction of the first component 1 and the second component 2 , the third hole 22 is adapted to the second hole 12 .
[0055] The third hole 22 is adapted to the second hole 12, which means that when viewed along the arrangement direction of the first component 1 and the second component 2, the shape of the third hole 22 is the same as the shape of the second hole 12, and the size of the third hole 22 is the same as the size of the second hole 12, so that the rivet 3 can pass through the second hole 12 and the third hole 22 at the same time, and the rivet 3 can be interference fit or overfit with the second hole 12 and the third hole 22 at the same time to limit the relative position between the first component 1 and the second component 2 along the direction perpendicular to the arrangement direction of the first component 1 and the second component 2.
[0056] When the rivet 3 is interference-fitted or over-fitted with the second hole 12 and the third hole 22, please refer to Figures 3 to 5 , observed along the arrangement direction of the first component 1 and the second component 2, the connecting portion 31 is adapted to the second hole 12 or the third hole 22. The connecting portion 31 is adapted to the second hole 12 or the third hole 22. Taking the second hole 12 as an example, it means that the connecting portion 31 can be inserted into the second hole 12, and under the restriction of the second hole 12, the connecting portion 31 cannot move relative to the first component 1 along the opening direction of the second hole 12, that is, the connecting portion 31 can only move relative to the first component 1 along the opening direction of the second hole 12, or the connecting portion 31 can also rotate in the second hole 12 around the opening direction of the second hole 12. For example, please refer to Figures 3 to 5 , viewed along the arrangement direction of the first component 1 and the second component 2, the shape of the connecting portion 31 is the same as the shape of the second hole 12, and the size of the connecting portion 31 is the same as the size of the second hole 12, so that the connecting portion 31 is exactly inserted into the second hole 12. Based on the same principle, the connecting portion 31 is exactly inserted into the third hole 22.
[0057] In a specific embodiment, see Figure 3 and Figure 4 Observing along the arrangement direction of the first component 1 and the second component 2, the connecting portion 31, the second hole 12, and the third hole 22 are all circular. In this embodiment, the connecting portion 31 can rotate within the second hole 12 about the direction of the second hole 12, or rotate within the third hole 22 about the direction of the third hole 22. When there are multiple rivets 3, the multiple rivets 3 fix the position and angle between the first component 1 and the second component 2.
[0058] For the second component 2 above, see Figures 3 to 5 , the first component 1 can be in a sheet shape.
[0059] In some embodiments, see Figure 3 and Figure 4, there are multiple second components 2, and multiple second components 2 are riveted to the first component 1. It is understood that when the first component 1 and the second component 2 are positioned using the positioning posts 201 of the jig 200, if there are multiple second components 2, the first component 1 needs to be provided with multiple sets of fourth holes 13, resulting in a large number of fourth holes 13. Due to machining errors between the fourth holes 13 and the positioning posts 201, and the large number of fourth holes 13, some positioning posts 201 may not be properly inserted into the fourth holes 13, preventing the first component 1 from being properly positioned on the jig 200, and preventing the next step of riveting the first component 1 and the second component 2. This first component 1 will then need to be scrapped, increasing the production cost of the riveted structure 100. In the embodiment of the present application, the first component 1 and the second component 2 are directly positioned relative to each other using the first protrusion 11 and the first hole 21. This can alleviate the problem of the first component 1 being unable to be properly positioned on the jig 200, thereby reducing the production cost of the riveted structure 100.
[0060] In the riveted structure 100 of the present embodiment, the first protrusion 11 of the first component 1 at least partially penetrates the first hole 21 of the second component 2, thereby directly positioning the first component 1 and the second component 2 relative to each other. This helps to reduce the precision requirements for the first component 1 and the second component 2, improve the yield rate of the first component 1 and the second component 2, and reduce the production cost of the riveted structure 100. When there are multiple second components 2, the problem of the first component 1 not being able to be correctly positioned on the jig 200 can be alleviated, thereby reducing the production cost of the riveted structure 100.
[0061] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit them. Based on the concept of the present application, the technical features in the above embodiments or different embodiments can also be combined, the steps can be implemented in any order, and there are many other changes in different aspects of the present application as described above. For the sake of simplicity, they are not provided in detail.
