Description

Technical Field

[0001] This utility model relates to the field of component connection technology, specifically to a riveting structure. Background Technology

[0002] In modern manufacturing, riveting technology is an important connection method, widely used in automotive interior and exterior trim, bodywork, and other mechanical structures requiring fixed connections. A typical riveting method involves drilling holes at corresponding locations on the plastic and metal parts, inserting blind rivets, and then using a rivet gun (electric or pneumatic) to pull and cut the rivet's core, causing the other end of the rivet to expand and form a thickened head. This achieves a tight fit between the plastic and metal parts, preventing slippage.

[0003] For example, CN114001078A discloses a rivet, a riveting structure with synchronous and uniform interference along the axial direction, and a riveting process. Specifically, the rivet includes a rivet body and a rivet core. The rivet body has a tapered through hole along its axial direction, penetrating the rivet body and the rivet head. The rivet core passes through the tapered through hole, and at least part of the rivet core is in close contact with the tapered through hole. The contact part between the rivet core and the tapered through hole is tapered, and the taper of the contact part is the same as that of the tapered through hole. During the pulling of the rivet core, the rivet body and the rivet core can fit together tightly, so that after riveting, the rivet core, the rivet body and the hole wall of the fastening hole will produce synchronous and equal interference fit along the hole axial direction. This avoids the plastic flow of the material of the components to be connected caused by the pulling of the rivet core, thereby achieving the purpose of improving the fatigue strengthening effect.

[0004] While traditional connection methods can meet the requirements to a certain extent, they still have some shortcomings in practical applications. For example, the currently commonly used riveting method often relies on auxiliary parts such as rivets and screws, which not only makes the assembly process more complicated but also leads to higher costs. Utility Model Content

[0005] The purpose of this utility model is to overcome the above-mentioned technical deficiencies and propose a riveting structure to solve the technical problems of complex assembly process and high cost in the existing riveting method.

[0006] To achieve the above-mentioned technical objectives, the present invention adopts the following technical solution:

[0007] This utility model provides a riveting structure, including: a first connector and a second connector. The first connector has a riveting hole. A protruding riveting head is provided on one side of the second connector. The end of the riveting head forms a flange. When the riveting head is inserted into the riveting hole, the flange can pass through the riveting hole and fold outward to fit against the surface of the first connector.

[0008] In some embodiments, a flanged hole is provided inside the flanged portion. The flanged hole is used to accommodate the head of the riveting tool during the riveting process, so that the flanged portion can be folded outward from the outer edge of the flanged hole.

[0009] In some embodiments, the flange hole extends through the second connector.

[0010] In some embodiments, a chamfer is provided at the outer edge of the flanged hole.

[0011] In some embodiments, the riveting head further has a connecting portion, which engages with the riveting hole when the riveting head is inserted into the riveting hole.

[0012] In some embodiments, there are two or more riveting holes and riveting heads, and the positions of each riveting hole and each riveting head correspond respectively.

[0013] In some embodiments, the riveting head has a conical or cylindrical structure.

[0014] In some embodiments, the first connector has a first surface and a second surface. When the riveting head is inserted into the riveting hole, the first surface is in contact with one side of the second connector, and the second surface is used to cooperate with the folded flange.

[0015] In some embodiments, the second surface is provided with a limiting groove adapted to the flange portion, and the flange portion can be engaged in the limiting groove after being folded outward.

[0016] In some embodiments, the first surface is a plane.

[0017] Compared with existing technologies, the riveting structure provided by this utility model, by setting riveting holes and riveting heads on the first and second connecting parts respectively, allows the riveting head on the second connecting part to be inserted into the riveting hole on the first connecting part. Furthermore, the flange of the riveting head can be folded outward from the outer edge of the riveting hole to fit against the surface of the first connecting part, thereby ensuring a stable connection between the two. This riveting structure eliminates the need for bolts, screws, and rivets while achieving the same strength of fixation. Simultaneously, by eliminating intermediate fixing parts, it effectively reduces costs.

[0025] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0026] To address the technical problems of complex assembly processes and high costs associated with riveting, this utility model provides a flip-riveting structure that eliminates the need for bolts, screws, and rivets while achieving the same level of fixing strength. Furthermore, by eliminating intermediate fixing parts, costs are effectively reduced. The flip-riveting structure offers a simple riveting process, provides a firm and reliable fixation, and saves the steps of installing bolts and screws, thereby shortening riveting time, reducing installation time, and improving fixing efficiency.

[0027] It should be noted that the riveting structure described in this utility model is used for, but not limited to, the connection of metal parts and plastic parts. For ease of explanation, this utility model only uses the application of the riveting structure to the connection of metal parts and plastic parts as an example. The principle of the riveting structure in the connection of other types of structural parts is essentially the same as that in the connection of metal parts and plastic parts, and will not be elaborated here. In addition, the riveting structure of this utility model can be used for component connection in the fields of automobile manufacturing, aerospace, and machinery manufacturing, and can meet the connection requirements in various complex environments. At the same time, because the riveting structure connection process of this utility model is simple and low in cost, it can also be used in some fields with high cost requirements, such as home appliance manufacturing and building installation.

[0028] Please see Figures 1 to 4The riveting structure includes a first connector 1 and a second connector 2. The first connector 1 has a riveting hole 11. A protruding riveting head 21 is provided on one side of the second connector 2. When the connection operation is performed, the protruding riveting head 21 is inserted into the riveting hole 11 of the first connector 1. In order to ensure the firmness of the connection, the end of the riveting head 21 forms a flange. When the riveting head 21 is inserted into the riveting hole 11 of the first connector 1, the flange can pass smoothly through the riveting hole 11. After passing through, the flange can be folded outward and attached to the surface of the first connector 1, thereby fixing the first connector 1 and the second connector 2.

[0029] In this device, the riveting head 21 on the second connector 2 is inserted into the riveting hole 11 on the first connector 1, and the flange of the riveting head 21 is folded outward from the outer edge of the riveting hole 11 to fit against the surface of the first connector 1, forming a cap structure for positioning, thereby achieving a stable connection between the two. This solution eliminates traditional rivet parts. When connecting components, only one riveting hole 11 needs to be made on one structural component, and a riveting head 21 needs to be stretched out on the other structural component. After the riveting head 21 is inserted into the riveting hole 11, the riveting head of the riveting machine is used to rivet the riveting head 21, thus achieving a tight and fixed connection between the two structural components. The riveting structure of this solution has the advantages of simple structure, easy operation, and stable connection. In practical applications, this riveting structure can effectively improve connection efficiency, reduce production costs, and also improve the overall quality and reliability of the product, so as to facilitate the application of the riveting method to the mass production or verification stage. In addition, the riveting structure is simple and easy to implement. The corresponding structure can be reserved in the early structural design according to the user's own needs, and the riveting structure can be produced at the same time during the parts production process.

[0030] It should be noted that this solution employs a specific connector design, where the first connector is a plastic component and the second connector is a metal component. By utilizing the riveting head 21 on the metal connector, a robust cap structure can be formed. This structure not only effectively secures the plastic component, ensuring its stability during use, but also provides sufficient strength and durability to cope with various working environments and conditions.

[0031] In some possible embodiments, the flange portion has a flange hole 22 inside. In specific implementation, a special riveting tool can be used to insert the riveting head 21 on the second connector 2 into the flange hole 22 of the flange portion, and the head of the riveting tool can be used to fold the flange portion inside the flange hole 22 to complete the entire riveting process.

[0032] To facilitate the setting of the riveting head 21 and the fabrication of the flanged hole 22 on the second connector 2, in some possible embodiments, the flanged hole 22 is designed to penetrate the second connector 2. In actual fabrication, a pre-drilled hole can be made on the second connector 2 first, and then a special mold or tool can be used to stretch the hole to form the required riveting head 21 and flanged hole 22. This design not only simplifies the fabrication process of the flanged hole 22 but also improves fabrication efficiency and precision. Simultaneously, a chamfer is provided at the outer edge of the flanged hole 22, making it easier for the riveting tool to be inserted and moved, allowing the flanged part to fold smoothly outward from the outer edge of the flanged hole 22, further improving the convenience and efficiency of the riveting operation.

[0033] In some possible embodiments, the riveting head 21 also includes a connecting portion, which, together with the flange portion, constitutes the entire structure of the riveting head 21. When the riveting head 21 is inserted into the riveting hole 11, the connecting portion and the riveting hole 11 can fit perfectly together and connect. Furthermore, the width of the connecting portion is designed to be equal to the thickness of the connection point of the first connecting member 1. This design allows the second connecting member 2 to stably connect with the first connecting member 1, thereby enhancing the stability and strength of the connection. It can be seen that the width of the riveting head 21 is designed to be larger than the thickness of the first connecting member 1. This design ensures that during the insertion of the riveting head 21 into the riveting hole 11, the flange portion of the riveting head 21 can smoothly pass through the riveting hole 11 and protrude from the surface of the riveting hole 11, thus facilitating subsequent riveting operations.

[0034] In some possible embodiments, there are two or more riveting holes 11 and riveting heads 21, and the positions of each riveting hole 11 and each riveting head correspond to their respective positions. The arrangement of multiple riveting holes 11 and riveting heads 21 can distribute the force at the connection point, making the entire connection structure more robust and durable. In practical applications, the appropriate number and position of riveting holes 11 and riveting heads 21 can be selected according to specific needs and the working environment to achieve the best connection effect.

[0035] In this embodiment, preferably, a cylindrical riveting head 21 is used, with cylindrical flanged holes 22 designed inside. There are three flanged holes 11, with their centers aligned on the same straight line. Simultaneously, there are also three corresponding riveting heads 21, with their positions corresponding one-to-one with the flanged holes 11, ensuring the accuracy and efficiency of the riveting process.

[0036] In some possible embodiments, the first connector 1 is further provided with a certain mating structure on both sides of the riveting hole 11. For ease of explanation, the two sides of the first connector 1 are defined as the first surface 12 and the second surface 13, respectively. When the riveting head 21 is inserted into the riveting hole 11, its first surface 12 will tightly fit against one side of the second connector 2. The first surface 12 is designed as a smooth surface. The smooth surface design not only facilitates the manufacturing process, but also effectively enables the first connector 1 and the second connector 2 to fit together, thereby improving the stability and strength of the connection. In addition, the second surface 13 is used to mate with the folded flange. In order to ensure that the flange can be firmly engaged after folding, a limiting groove 14 adapted to the shape of the flange is designed at the position corresponding to the riveting hole 11 on the second surface 13. When the flange is folded outward, it can be precisely engaged and fixed in the corresponding limiting groove 14, thereby ensuring the reliability and durability of the riveting structure.

[0037] Working principle: In use, a riveting hole 11 needs to be made at a predetermined position on the plastic part first, and a riveting pressure head 21 with a flanged hole 22 is stretched on the metal part. After stretching, the riveting pressure head 21 is inserted into the pre-made riveting hole 11 on the plastic part. Then, the operator uses the riveting head of the riveting machine to perform riveting operation on the flanged hole 22 using a vertical spin riveting method. During the riveting process, the flanged part of the riveting pressure head 21 will gradually increase, eventually forming a firm cap. The cap can tightly adhere the plastic part and the metal part that need to be fixed together. This fixing method can effectively prevent the parts from loosening during use, thereby achieving the function of stably fixing different types of parts together.

[0038] This invention provides riveting holes 11 and riveting heads 21 on the first connector 1 and the second connector 2, respectively. The riveting head 21 on the second connector 2 can be inserted into the riveting hole 11 on the first connector 1. Furthermore, the flange of the riveting head 21 can be folded outwards from the outer edge of the riveting hole 11 to fit against the surface of the first connector 1, thus ensuring a stable connection between the two. This riveting structure eliminates the need for bolts, screws, and rivets while achieving the same strength of fixation. Simultaneously, by eliminating intermediate fixing parts, it effectively reduces costs. The riveting process of the riveting structure is simple to operate, provides a firm and reliable fixation, and saves the steps of installing bolts and screws, thereby shortening the riveting time, saving installation and fixing time, and improving fixing efficiency.
