Detailed implementation manners

[0027] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments:

[0028] The assembly of a hole and a shaft is generally carried out by riveting and pressing, and the reliability of riveting will directly affect the connection quality of the product. During the riveting process, in order to achieve a fastening effect, there is an interference fit between the component and the hole. During the assembly process, the interference fit part is likely to cause material cutting, and the cut material is blocked inside the hole or between the hole and the shaft, resulting in the problem of stuck material.

[0029] Based on reducing the problem of stuck material, an embodiment of the present application provides a component 1. Referring to Figures 1 - 3 , the component 1 includes a base portion 110 and a riveting and pressing portion 111. The riveting and pressing portion 111 protrudes from the base portion 110 in a direction away from the base portion 110. The riveting and pressing portion 111 can be riveted and abutted against an external component to achieve riveting and fixing with the external component. At least a part of the riveting and pressing portion 111 extends along the circumferential direction of the base portion 110, and the riveting and pressing portion 111 can be riveted and abutted against an external component. When the component 1 is riveted and cooperated with an external component, the riveting and pressing portion 111 can abut against the external component, and at least a part of the riveting and pressing portion 111 extends along the circumferential direction of the base portion 110, which is convenient to meet the riveting requirements of the component 1 and the external component. Compared with directly riveting through the outer side wall, it avoids large-area riveting deformation and reduces the problem of material cutting caused by the tight fit relationship between the components 1.

[0030] It should be noted that during the riveting process, in order to achieve a fastening effect, there is an interference fit between the component and the hole. Therefore, in the present application, "riveting fit" refers to the fit relationship formed after the component 1 is riveted with an external component, such as an interference fit.

[0031] The riveting and pressing portion 111 protrudes from the base portion 110. When riveted and connected with an external component, the riveting and pressing portion 111 can abut against the external component. Compared with directly riveting through the outer side wall of the component 1, it avoids large-area riveting deformation and reduces the problem of material cutting caused by the tight fit relationship between the components 1.

[0032] Here, the component 1 can be a shaft component 1, and the shaft component 1 can be riveted and cooperated with the groove wall of an external component. The component 1 can also be a mating component 1 with a groove, and at least a part of the external component can pass through the groove of the mating component 1 and be riveted and cooperated with the groove wall of the mating component 1. Define a first direction and a second direction. When the component 1 is a shaft component 1, the first direction is the extending direction of the shaft component 1. When the component 1 is a mating component 1 with a hole, the first direction is the extending direction of the central axis of the hole, which can also be understood as the assembly direction when the component 1 and the external component are assembled. The outer contour of the cross-section of the shaft component 1 can be circular or non-circular, and the shape of the component 1 is not limited here.

[0033] It should be noted here that when the extending direction of the shaft member 1 is more than one, the extending direction of the portion of the shaft member 1 that mates with the hole of the external member shall prevail. The second direction is perpendicular to the first direction, and there can be multiple second directions. The first direction and the second direction here are mainly used to illustrate the relative positions of components such as the riveting portion 111.

[0034] Referring to Figures 2 - 8 , along the second direction, define the perpendicular distance from one end of the riveting portion 111 away from the base portion 110 to the center line of the member 1 as L1, the perpendicular distance from the groove wall of the installation groove 13 to the center line of the member 1 as L2, and half of the difference between the perpendicular distance from the groove wall of the installation groove 13 to the center line of the member 1 and the perpendicular distance from the base portion 110 to the center line of the member 1 as L3. The height of the riveting portion 111 in the second direction is L4. There is always L4 > L3, and the range of L4 is 0.01 mm - 0.05 mm. Optionally, the size of L4 is 0.03 mm.

[0035] Referring to Figure 2 and Figure 4 , in one embodiment, the riveting portion 111 is located on the outer peripheral side of the member 1, and the riveting portion 111 protrudes relative to the outer peripheral wall of the base portion 110. Correspondingly, the external member has an installation groove 13. When assembling the member 1 and the external member, at least part of the member 1 passes through the installation groove 13 of the external member, and the riveting portion 111 deforms and abuts against the wall of the installation groove 13 to form a tight fit, and there is L1 > L2;

[0036] Referring to Figure 2 , Figure 4 and Figure 5 , in another embodiment, the member 1 has an installation groove 13, and at least part of the riveting portion 111 is located on the inner peripheral side defining the installation groove 13. The riveting portion 111 protrudes inward relative to the wall defining the installation groove 13. When assembling the member 1 and the external member, at least part of the external member passes through the installation groove 13 of the member 1, and the riveting portion 111 deforms and forms a tight fit with the outer side wall of the external member, and there is L2 - L1 > L3;

[0037] It should be noted that the inner side of the installation groove 13 here is used to explain the protruding direction of the riveting portion 111, including various situations: the installation groove 13 is recessed relative to the wall of the member 1 to form an installation cavity, and the riveting portion 111 protrudes toward the side of the installation cavity. The installation groove 13 can include a plane and / or a curved surface. When the installation groove 13 includes a curved surface, the curved surface can protrude or be recessed relative to the installation cavity.

[0038] Referring to Figure 6 and Figure 7, at least a part of the riveting portion 111 extends along the extending direction of the central line of the base portion 110. In some embodiments, the riveting portion 111 may be a closed-loop surrounding structure with the central line of the base portion 110 as the axis, or a helically surrounding structure with the central line of the base portion 110 as the axis. In some other embodiments, the riveting portion 111 may also be a surrounding and juxtaposed structure with the central line of the base portion 110 as the axis. Optionally, when the riveting portion 111 is surrounding and juxtaposed with the central line of the base portion 110 as the axis, the riveting portions 111 are evenly arranged along the surrounding direction. On the one hand, it can increase the riveting length; on the other hand, under the action of the same force, the second end is more likely to deform than the first end. On the premise that the positions of the two side riveting portions are opposite, during the riveting process of the component 1 and the external component, it can improve the uniformity of the circumferential force during the riveting process of the component 1 and play an auxiliary centering effect. This design reduces the contact area between the component 1 and the external component compared with directly riveting through the outer wall, and reduces the problem of inclination of the component 1 caused by uneven interference during the riveting process.

[0039] Refer to Figure 3 and Figure 5 , along the second direction, the riveting portion 111 includes a first end 111c and a second end 111d. The first end 111c is connected to the base portion 110, and the second end 111d is a cantilever end. Along the first direction, the size of the second end 111d is smaller than that of the first end 111c. Since the size of the second end 111d is smaller than that of the first end 111c, under the action of the same force, the second end 111d is more likely to deform than the first end 111c. When the component 1 and the external component are riveted, the second end 111d can deform to adapt to the assembly gap between the two components 1, and the second end 111d and the external component form an interference fit to achieve the purpose of riveting.

[0040] The external component has a mating wall 12a. After the component 1 and the external component are assembled, at least a part of the riveting portion 111 abuts against the mating wall 12a. Along the second direction, there is a gap between the first end 111c and the mating wall 12a. During the assembly process of the component 1 and the external component, only the riveting portion 111 and the mating wall 12a of the external component deform and abut against each other, and the first end 111c and the mating wall 12a do not contact each other, which is beneficial to reducing the problem of cutting material caused by large-area interference, thereby reducing the problem of jamming materials and is beneficial to improving the quality of the assembled component 1.

[0041] Furthermore, along the first direction, there are two or more riveting portions 111 arranged in parallel. After the component 1 and the external component are assembled, the riveting portion 111 can abut against the mating wall 12a. The first direction is also the assembly direction. A part of the riveting portion 111 is in interference fit with the mating wall 12a. During the assembly process, the second end 111d of the riveting portion 111 is deformed. Also, since there is a gap between the first end 111c of the component 1 and the mating wall 12a of the external component in the second direction, the assembly of the component 1 and the external component may be unstable by abutting one riveting portion 111 against the mating wall 12a. Arranging two or more riveting portions 111 in the first direction is beneficial to improving the assembly stability of the component 1 and the external component. The portions of the riveting portion 111 abutting against the mating portion 121 are arranged at intervals, so that at least two force application points are formed between the component 1 and the external component through the riveting portion 111, and the assembly effect is better.

[0042] The component 1 includes a guiding portion 112 and an end portion 113. The end portion 113 is located at one end of the component 1. The end portion 113 refers to the starting end of the assembly direction of the component 1, that is, the external component is assembled from the starting end to the terminal end. Here, the starting end and the terminal end are used to refer to the assembly direction, and the relative positions of the component 1 and the external component after assembly are not restricted. Along the first direction, the guiding portion 112 is closer to the end portion 113 than the riveting portion 111. One end of the guiding portion 112 is connected to the end portion 113, and the other end of the guiding portion 112 is connected to the base portion 110 or the riveting portion 111. Along the first direction, from the end portion 113 to the riveting portion 111, when the riveting portion is located on the outer peripheral side of the base portion 110, the guiding portion 112 is arranged with an enlarged diameter, that is, during the assembly process of the component 1 and the external component, along the assembly direction of the component 1 relative to the external component, the guiding portion 112 forms a reduced opening, which can guide a part of the component 1 to pass through the installation groove 13 of the external component; when at least part of the riveting portion 111 is located on the inner peripheral wall of the installation groove 13, the wall forming the installation groove 13 includes the wall of the guiding portion 112. Along the first direction, from the end portion 113 to the riveting portion 111, the cavity formed by the guiding portion 112 is arranged with a reduced diameter, and during the assembly process of the component 1 and the external component, the guiding portion 112 can guide the assembly of the component 1 and the external component.

[0043] The riveting part 111 is made of metal material, and the component 1 is an integral structure, which can be formed by machining, casting, forging or other means. After the riveting process, a welding step is further included to fix the component and the external component. Adding a riveting step before the welding step, on the one hand, the component 1 is assembled in advance, and there is no need for a tooling to fix the component 1 in the welding step. On the other hand, it can position the component 1 in advance for assembly, improving the centering effect of the component 1 compared with direct welding. Specifically, in this embodiment, the component 1 includes an aluminum alloy material, and the component 1 can be used as a connecting pipe or a component connecting the connecting pipes for the thermal management system. Specifically, this embodiment is particularly applicable to the case where the thickness of the riveting position is small, such as a heat exchange device. Since the riveting thickness of the component 1 is small, it is difficult to ensure the accurate centering of the component 1. The second end provided in this solution is more easily deformed than the first end, and a plurality of riveting parts 111 are arranged side by side in the first direction. On the premise that the positions of the two sides of the riveting parts 111 are opposite, during the riveting process of the component 1 and the external component, the uniformity of the circumferential force on the component 1 during the riveting process can be improved, achieving an auxiliary centering effect and reducing the offset of the component 1. When the connection assembly of the embodiment of the present invention is applied to the heat exchange device of the thermal management system, the first component 11 can be a connecting pipe structure, and the second component 12 can be a plate structure. The fluid enters or leaves the heat exchange device through the connecting pipe structure.

[0044] In other embodiments, it can also be used as a rod or the like. In some other embodiments, the riveting part 111 can also be made of plastic material.

[0045] The embodiment of the present application also provides a connection assembly 2. Refer to Figures 9 - 12 , which includes two components 1 connected by riveting. At least one of the components 1 includes a base part 110 and a riveting part 111. Along the second direction, the riveting part 111 protrudes relative to the base part 110. The riveting part 111 includes a protruding part 111e. Along the first direction, there are two or more protruding parts 111e arranged side by side. The protruding part 111e surrounds the entire circumference of the base part 110 along the circumferential direction or is arranged at intervals along the circumferential direction. The second ends 111d of adjacent protruding parts 111e are arranged at intervals. The protruding part 111e surrounds the entire circumference of the base part 110 along the circumferential direction or is arranged at intervals along the circumferential direction. At least one of the other components 1 includes a mating part 121, and the riveting part 111 and the mating part 121 are in abutting cooperation.

[0046] Refer to Figure 10 and Figure 11, the component 1 includes a first component 11 and a second component 12. The first component 11 is a shaft component, and the first component 11 includes a connecting portion. The second component 12 is a mating component 1 with a mounting groove 13. At least part of the connecting portion is located in the mounting groove 13 of the second component 12. The connecting portion is used to connect the second component 12, and the first component 11 and the second component 12 are riveted and pressed together. The connecting assembly 2 further includes a riveting portion 111 and a mating portion 121. One of the riveting portion 111 and the mating portion 121 is located on the first component 11, and the other of the riveting portion 111 and the mating portion 121 is located on the second component 12. The riveting portion 111 abuts against the mating portion 121;

[0047] Referring to Figure 12 , or, the riveting portion 111 includes a first riveting portion 111a and a second riveting portion 111b, and the mating portion 121 includes a first mating portion 121a and a second mating portion 121b. The first riveting portion 111a and the second mating portion 121b are located on the first component 11, and the second riveting portion 111b and the first mating portion 121a are located on the second component 12. The first riveting portion 111a abuts against the first mating portion 121a, and the second riveting portion 111b abuts against the second mating portion 121b.

[0048] Referring to Figure 3 and Figure 5 , the riveting portion 111 protrudes away from the base portion 110. The riveting portion 111 includes a first end 111c and a second end 111d. The first end 111c is connected to the base portion 110, and the second end 111d extends away from the base portion 110 relative to the first end 111c. Along the first direction, the size of the second end 111d is smaller than the size of the first end 111c. The mating portion 121 includes a mating wall 12a. In the state where the first component 11 and the second component 12 are assembled, the riveting portion 111 includes a deformed portion. At least part of the deformed portion is located at the second end 111d. The deformed portion abuts against the mating wall 12a and is in an interference fit to form a riveted connection. Along the second direction, there is a gap between the first end 111c and the mating wall 12a. During the assembly process of the two components 1, only the deformed portions of the riveting portion 111 and the mating wall 12a of the mating portion 121 are deformed and abutted, and the first end 111c and the mating wall 12a do not contact, which is beneficial to reducing the problem of cutting material caused by large-area interference, thereby reducing the problem of stuck material and being beneficial to improving the quality of the assembled component 1. On the other hand, in the subsequent welding step of the cutting material problem, the presence of debris on the welding surface is likely to cause

[0049] It should be noted that the deformed portion here refers to the deformation of the riveting portion 111 caused by assembly. In the assembled state, the deformed portion bends toward one side in the first direction relative to the first end 111c. Specifically, it bends in the opposite direction to the assembly direction of the component 1. Actually, it may also be deformed due to wear, resulting in the deformed portion being invisible to the naked eye.

[0050] Specifically, in the assembled state, the riveting portion 111 and the mating portion 121 are in abutting contact and interference fit, and there are at least three embodiments herein:

[0051] In one embodiment, the first member 11 includes a base portion 110 and a riveting portion 111. The first member 11 is a shaft member 1.

The second member 12 includes an end portion 113. The second member 12 has a mounting groove 13, and the mounting groove 13 forms a depression relative to the end portion 113 for accommodating at least a part of the first member 11.

The second member 12 is a shaft member 1, and the mating wall 12a is the outer side wall of the shaft member 1. At least a part of the second member 12 is located in the mounting groove 13;

[0053] In other embodiments, the first member 11 is a shaft member 1, the second member 12 is a mating member 1 having a mounting groove 13, and the second member 12 is the inner side wall of the mounting groove 13. The first member 11 includes a first riveting portion 111a, and the first riveting portion 111a protrudes relative to the base portion 110; the second member 12 includes a second riveting portion 111b, and the second riveting portion 111b protrudes from the mating wall 12a toward the center of the mounting groove 13.
