Technical Field

[0001] The present application relates to the field of batteries, and in particular to a rivet nut, a battery and an electrical device. Background Art

[0002] A rivet nut is a nut that is fastened to a connected piece by rivet. The rivet nut can lock and connect two workpieces at one end. However, the rivet nut cannot meet the requirements of locking more workpieces, which limits the use of rivet nuts. Utility Model Content

[0003] In view of the above problems, the present application provides a rivet nut, a battery and an electrical device, which can enable the rivet nut to connect more workpieces and expand the use scenarios of the rivet nut.

[0004] In a first aspect, the present application provides a rivet nut, comprising a flange portion, a rod portion and a connecting portion, wherein the rod portion comprises a first end and a second end along the axial direction of the rod portion, the flange portion is connected to the first end, and the connecting portion is connected to the second end, the flange portion protrudes from the rod portion in a radial direction of the rod portion, the first end is configured to be connected to a first workpiece, and the connecting portion is configured to be connected to a second workpiece.

[0005] In the technical solution of the embodiment of the present application, along the axial direction of the rod, the flange portion is connected to the first end of the rod portion, and the connecting portion is connected to the second end of the rod portion. The first end can be riveted to the first workpiece, and the connecting portion can be connected to the second workpiece. Furthermore, the rivet nut can be fixedly connected to different workpieces on both sides, meeting the requirement of the rivet nut to lock more workpieces and expanding the use scenarios of the rivet nut.

[0006] In some embodiments, the connecting portion is provided with a first thread.

[0007] The first thread can be threadedly connected with the thread of a fastener such as a nut or a bolt, so that the fastener can be conveniently connected to the connecting portion to lock the second workpiece.

[0008] In some embodiments, the connecting portion includes a coaxially arranged connecting segment and a locking segment, the connecting segment connects the locking segment and the rod portion, the rod portion, the connecting segment and the locking segment are cylindrical, the diameter of the rod portion is larger than the diameter of the connecting segment, and the first thread is arranged on the circumferential side of the locking segment.

[0009] The first thread is arranged on the circumferential side of the locking section. The first thread is an external thread of the locking section, and can be conveniently connected with a thread (such as an internal thread) of a fastener such as a nut. During assembly, the fastener is inserted into the locking section from the end of the locking section away from the connecting section, the first thread is connected with the internal thread of the fastener, and the fastener is rotated to lock the second workpiece on the connecting portion.

[0010] In some embodiments, the locking section has an end away from the connecting section with a first chamfer structure, the first chamfer structure connects the end of the first thread away from the connecting section, and / or the locking section has an end connected to the connecting section with a second chamfer structure, the second chamfer structure connects the end of the first thread close to the connecting section.

[0011] The first chamfered structure and the second chamfered structure can guide the locking section to pass into and out of the second through hole, which is beneficial to improving assembly efficiency.

[0012] In some embodiments, the rivet nut is provided with a first opening, the first opening passes through the end surface of the connecting portion away from the rod portion and extends toward the first end, and the first thread is provided on a hole wall of the first opening.

[0013] The first thread is an internal thread of the connection part, which can be easily connected with the external thread of a fastener such as a bolt or a screw. During assembly, the connection part is located in the second through hole, the fastener is inserted into the connection part from the end of the connection part away from the rod part, the first thread is connected with the external thread of the fastener, and the fastener is rotated to lock the second workpiece on the connection part.

[0014] In some embodiments, the rivet nut is provided with a second opening and a second thread, the second opening passes through the flange portion and extends toward the second end, and the second thread is provided on the hole wall of the second opening.

[0015] The second opening extends through the flange and into the inside of the rod. The diameter of the second opening in the radial direction of the rivet nut is smaller than the size of the rod. When the rivet nut is used to lock the third workpiece (such as the socket of the connector), the fastener (such as a bolt or a screw, etc.) passes through the opening and the second opening on the third workpiece in sequence and extends into the rod. The external thread on the fastener is connected with the second thread. The fastener is rotated so that the fastener locks the third workpiece on the rivet nut, thereby installing and fixing the third workpiece on the first workpiece (such as a plug-in panel). Since the rivet nut is used after riveting, the second opening can also be used for the rivet tool to extend into the rod to act on the rod to deform the rod, thereby fixing the rivet nut on the first workpiece.

[0016] In some embodiments, in the axial direction of the rod portion along the direction from the flange portion to the connecting portion, the second opening includes a first section and a second section, the hole diameter of the first section is larger than the hole diameter of the second section, and the second thread is arranged on the hole wall of the second section.

[0017] The hole diameter of the first section is larger than that of the second section, that is, the wall thickness of the rod at the position corresponding to the first section is smaller than that at the position corresponding to the second section. Since the first end of the rod connected to the flange may be deformed during the riveting process of the rivet nut, the wall thickness of the rod at the position corresponding to the first section is smaller, which can facilitate the riveting of the rivet nut and improve the usability of the rivet nut.

[0018] In some embodiments, the flange portion includes a first surface facing away from the rod portion and a second surface facing the rod portion, and the rivet nut includes a plurality of ribs, which are arranged at intervals and connect the second surface and the rod portion along the circumference of the rod portion.

[0019] The ribs can provide support between the flange and the rod, and enhance the connection strength between the flange and the rod. In addition, since the second surface of the flange is attached to the surface of the first workpiece during the use of the rivet nut, the ribs can be embedded in the first workpiece after the rivet nut is riveted, thereby preventing the rivet nut from rotating under stress, thereby increasing the fastening performance of the rivet nut.

[0020] In some embodiments, a circumferential side surface of the first end is provided with a convex-concave structure.

[0021] During the use of the rivet nut, the rod extends into the first through hole of the first workpiece, and the first end is at least partially located in the first through hole. During the rivet process of the rivet nut, the first end may be deformed by rivet, so as to fit into the hole wall of the first through hole, so that the rivet nut is fixedly connected to the first workpiece. Therefore, in the case where the concave-convex structure is provided on the circumferential side surface of the first end, during the rivet deformation of the concave-convex structure at the first end, the convex part of the concave-convex structure may be embedded in the hole wall of the first through hole, and the hole wall of the first through hole may be embedded in the concave part of the concave-convex structure, thereby preventing the rivet nut from rotating under force, thereby further increasing the fastening performance of the rivet nut.

[0022] In a second aspect, an embodiment of the present application provides a battery, the battery comprising the rivet nut of any of the above embodiments.

[0023] In some embodiments, the battery includes a connector panel and a protective cover plate, the connector panel is provided with a first through hole, the protective cover plate is provided with a second through hole, the rod portion is penetrated by the first through hole, the connecting portion is penetrated by the second through hole, the rivet nut includes a convex ring, the convex ring is provided on the circumferential side of the rod portion and protrudes from the rod portion in the radial direction of the rod portion, and the convex ring and the flange portion clamp the connector panel.

[0024] During the use of the rivet nut, the rod passes through the first through hole of the plug-in panel. The rod forms a convex ring during the riveting process. The convex ring and the flange clamp the plug-in panel, thereby riveting the rod and the plug-in panel, ensuring the connection strength between the plug-in panel and the rivet nut.

[0025] In a third aspect, an embodiment of the present application provides an electrical device, which includes a battery according to any one of the above embodiments, and the battery is used to provide electrical energy.

For those of ordinary skill in the art, the specific meanings of the above terms in the embodiments of the present application can be understood according to the specific circumstances.

[0052] At present, from the perspective of market development, the application of power batteries is becoming more and more extensive. Power batteries are not only used in energy storage power systems such as hydropower, thermal power, wind power and solar power stations, but also widely used in electric vehicles such as electric bicycles, electric motorcycles, electric cars, as well as military equipment and aerospace and other fields. With the continuous expansion of the application field of power batteries, the market demand is also constantly expanding.

[0053] The inventor of the present application noticed that in the related art, one end of the rivet nut used in the battery has only an internal thread, and the connection interface can only be locked at this end. When the other end of the rivet nut also needs to be locked to the connection interface, other fasteners need to be added for connection. For example, in some connector installation interfaces, after the connector is locked to the plug panel, a plastic protective cover needs to be locked on the back of the plug panel to protect the connector pins. At present, rivet nuts cannot meet the requirements of locking more workpieces, resulting in limited use scenarios of rivet nuts.

[0054] In order to reduce the use of fasteners and solve the problem of limited application scenarios of rivet nuts, the inventor of this application has studied and found that a rivet nut with a connecting portion at the tail end is designed. The rivet nut can be riveted with a first workpiece (such as a battery plug panel), and its internal thread is used to match the bolt to fix the connector, and the connecting portion at the tail end is used to match the nut, bolt, etc. to fix the second workpiece (such as a protective cover).

[0055] The present application provides a rivet nut, wherein a flange portion is connected to the first end of the rivet nut, and a connecting portion is provided at the second end of the rivet nut, and the connecting portion is configured to connect to a second workpiece. Thus, the rivet nut can be fixedly connected to two workpieces on both sides respectively, thereby meeting the requirement that the rivet nut locks more workpieces, expanding the use scenarios of the rivet nut, and also reducing the use of fasteners.

[0056] The rivet nut disclosed in the embodiment of the present application can be applied to, including but not limited to, batteries. The battery can be used as a power source for electrical devices or various energy storage systems that use batteries as energy storage elements. Electrical devices can be, but are not limited to, mobile phones, tablets, laptops, electric toys, electric tools, battery cars, electric cars, ships, spacecraft, etc. Among them, electric toys can include fixed or mobile electric toys, such as game consoles, electric car toys, electric ship toys, and electric airplane toys, etc., and spacecraft can include airplanes, rockets, space shuttles, and spacecraft, etc.

[0057] For the convenience of description, the following embodiments are described by taking a vehicle 1000 as an example of an electrical device according to an embodiment of the present application.

[0058] Please refer to Figure 1 , Figure 1A schematic diagram of the structure of a vehicle 1000 provided for some embodiments of the present application. The vehicle 1000 may be a fuel vehicle, a gas vehicle or a new energy vehicle, and the new energy vehicle may be a pure electric vehicle, a hybrid vehicle or an extended-range vehicle, etc. A battery 100 is provided inside the vehicle 1000, and the battery 100 may be provided at the bottom, head or tail of the vehicle 1000. The battery 100 may be used to power the vehicle 1000, for example, the battery 100 may be used as an operating power source for the vehicle 1000. The vehicle 1000 may also include a controller 200 and a motor 300, and the controller 200 is used to control the battery 100 to power the motor 300, for example, for starting, navigating and driving the vehicle 1000.

[0059] In some embodiments of the present application, the battery 100 can not only serve as an operating power source for the vehicle 1000, but also serve as a driving power source for the vehicle 1000, replacing or partially replacing fuel or natural gas to provide driving power for the vehicle 1000.

[0060] Please refer to Figure 2 , Figure 2 An exploded view of a battery 100 provided in some embodiments of the present application. The battery 100 includes a box 10 and a battery cell 20, and the battery cell 20 is contained in the box 10. Among them, the box 10 is used to provide a storage space for the battery cell 20, and the box 10 can adopt a variety of structures. In some embodiments, the box 10 may include a first part 11 and a second part 12, the first part 11 and the second part 12 cover each other, and the first part 11 and the second part 12 jointly define a storage space for accommodating the battery cell 20. The second part 12 may be a hollow structure with one end open, the first part 11 may be a plate-like structure, and the first part 11 covers the open side of the second part 12, so that the first part 11 and the second part 12 jointly define a storage space; the first part 11 and the second part 12 may also be hollow structures with one side open, and the open side of the first part 11 covers the open side of the second part 12. Of course, the box 10 formed by the first part 11 and the second part 12 may be in a variety of shapes, such as a cylinder, a cuboid, etc.

[0061] In the battery 100, there may be multiple battery cells 20, and the multiple battery cells 20 may be connected in series, in parallel, or in a mixed connection. A mixed connection means that the multiple battery cells 20 are both connected in series and in parallel. The multiple battery cells 20 may be directly connected in series, in parallel, or in a mixed connection, and then the whole formed by the multiple battery cells 20 is accommodated in the box 10; of course, the battery 100 may also be a battery module formed by connecting multiple battery cells 20 in series, in parallel, or in a mixed connection, and then the multiple battery modules are connected in series, in parallel, or in a mixed connection to form a whole, and accommodated in the box 10. The battery 100 may also include other structures, for example, the battery 100 may also include a busbar component for realizing electrical connection between the multiple battery cells 20.

[0062] Each battery cell 20 may be a secondary battery or a primary battery, or a lithium-sulfur battery, a sodium-ion battery, or a magnesium-ion battery, but is not limited thereto. The battery cell 20 may be cylindrical, flat, rectangular, or in other shapes.

[0063] Please refer to Figures 3 to 5 The embodiment of the present application provides a rivet nut 30, which includes a flange portion 301, a rod portion 302 and a connecting portion 303. Along the axial direction of the rod portion 302, the rod portion 302 includes a first end 304 and a second end 305. The flange portion 301 is connected to the first end 304, and the connecting portion 303 is connected to the second end 305. The flange portion 301 protrudes from the rod portion 302 in the radial direction of the rod portion 302. The first end 304 is configured to be connected to a first workpiece 500, and the connecting portion 303 is configured to be connected to a second workpiece 600.

[0064] The present application does not specifically limit the shape and material of the rivet nut 30. Optionally, the various parts of the rivet nut 30 may be cylindrical with different diameters, the diameter of the flange portion 301 is larger than the diameter of the rod portion 302, and the diameter of the rod portion 302 may be larger than the diameter of the connecting portion 303. In one example, the rivet nut 30 is made of stainless steel.

[0065] The present application does not specifically limit the length of the connection portion 303. The length direction of the connection portion 303 may be along the axial direction of the rod portion 302. Optionally, in one embodiment, the length of the connection portion 303 may be greater than the thickness of the second workpiece 600, so that the connection portion 303 can pass through the second workpiece 600 and be connected to the fastener.

[0066] The rivet nut 30 can be applied to, including but not limited to, the battery 100. When applied to the battery 100, the battery 100 may include a plug-in panel 40 and a protective cover 41. The plug-in panel 40 is mounted on the box 10 or as a panel of the box 10. The plug-in panel 40 is connected to a socket of a connector on the side of the accommodating space of the box 10. The connector is used to connect an external device. The battery 100 can supply power to the external device, or the external device can charge the battery 100.

[0067] The pins of the connector can extend into the accommodation space and be electrically connected to the battery cell 20. The protective cover 41 can cover the pins of the connector to protect the pins of the connector.

[0068] The plug panel 40 can be used as the first workpiece 500, the protective cover 41 can be used as the second workpiece 600, and the connector can be used as the third workpiece. The pins of the connector can pass through the plug panel 40 and extend into the space between the plug panel 40 and the protective cover 41. Figure 6 and Figure 7 The plug-in panel 40 is provided with a first through hole 501 along the thickness direction, and the protective cover plate 41 is provided with a second through hole 601 along the thickness direction. The rod 302 of the rivet nut 30 can be provided with the first through hole 501, and the connecting portion 303 can be provided with the second through hole 601. The rod 302 is riveted to the plug-in panel 40, and the flange portion 301 is pressed on the side of the plug-in panel 40 away from the protective cover plate 41. When the rod 302 is riveted to the plug-in panel 40, the rod 302 forms a convex ring 306 during the riveting process. The convex ring 306 is provided on the circumferential side of the rod 302 and protrudes from the rod 302 in the radial direction of the rod 302. The convex ring 306 and the flange portion 301 clamp the plug-in panel 40, thereby ensuring the connection strength between the rod 302 and the plug-in panel 40.

[0069] The flange 301 protrudes from the rod 302 in the radial direction of the rivet nut 30, that is, the size of the flange 301 in the radial direction of the rivet nut 30 is greater than the size of the rod 302 in the radial direction of the rivet nut 30. During the use of the rivet nut 30, the size of the first through hole 501 of the first workpiece 500 is adapted to the rod 302. When the rod 302 extends into the first through hole 501, the flange 301 is attached to the surface of the first workpiece 500 away from the second workpiece 600. Therefore, the flange 301 can fix the relative position between the rivet nut 30 and the first workpiece 500 in the axial direction of the rod 302. Optionally, another rod 302 can be connected to the other side of the flange 301 away from the rod 302, which is not specifically limited in the present application.

[0070] In one embodiment, optionally, a portion of the connecting portion 303 is located in the second through hole 601, and the other portion passes through the second through hole 601. The portion of the connecting portion 303 located outside the second through hole 601 can be connected to a fastener (such as a nut), so that the fastener locks the protective cover 41 to the connecting portion 303, and then the rivet nut 30 can be used to lock the connector panel 40 and the protective cover 41 together, and the protective cover 41 can protect the pins of the connector.

[0071] The socket can be fixed on the patch panel 40 by passing bolts through the socket and connecting the rivet nuts 30 .

[0072] In the rivet nut 30 of the embodiment of the present application, along the axial direction of the rod portion 302, the flange portion 301 is connected to the first end 304 of the rod portion 302, and the connecting portion 303 is connected to the second end 305 of the rod portion 302. The first end 304 can be riveted to the first workpiece 500, and the connecting portion 303 can be connected to the second workpiece 600. Furthermore, the rivet nut 30 can be fixedly connected to two workpieces on both sides, thereby meeting the requirement of locking more workpieces with the rivet nut 30 and expanding the application scenarios of the rivet nut 30.

[0073] According to some embodiments of the present application, optionally, the connecting portion 303 is provided with a first thread 307 .

[0074] The first thread 307 can be threadedly connected with the thread of a fastener such as a nut or a bolt, so that the fastener can be conveniently connected to the connecting portion 303 to lock the second workpiece 600 .

[0075] It is understandable that in other embodiments, the connection portion 303 is not limited to being locked to the second workpiece using the first thread 307. The connection portion 303 is bent to lock the second workpiece when the second through hole is penetrated, or is connected to the second workpiece by interference fit.

[0076] According to some embodiments of the present application, optionally, please refer to Figure 4 The connecting portion 303 includes a coaxially arranged connecting segment 308 and a locking segment 309. The connecting segment 308 connects the locking segment 309 and the rod 302. The rod 302, the connecting segment 308 and the locking segment 309 are cylindrical. The diameter of the rod 302 is larger than the diameter of the connecting segment 308. The first thread 307 is arranged on the circumferential side of the locking segment 309.

[0077] The connecting section 308 and the locking section 309 can be arranged along the axial direction of the rod 302. The connecting section 308 can be located in the second through hole 601 of the second workpiece 600, and the locking section 309 can be located outside the second through hole 601. The first thread 307 is arranged on the circumferential side of the locking section 309, and the first thread 307 is an external thread of the connecting portion 303. The thread of a fastener (such as a nut) can be connected to the first thread 307, so that the fastener locks the second workpiece 600 on the connecting portion 303 through the locking section 309.

[0078] The diameter of the rod 302 is greater than the diameter of the connecting section 308. During the assembly process of the second workpiece 600 and the rivet nut 30, the connecting section 303 can pass through the second through hole 601. Since the diameter of the rod 302 is greater than the diameter of the connecting section 308, the end face of the second end 305 of the rod 302 has a portion protruding radially along the rod 302 compared to the connecting section 308. When the second workpiece 600 is abutted against the end face of the rod 302 protruding compared to the connecting section 308, it means that the second workpiece 600 is assembled in place, and then the second workpiece 600 is connected to the locking section 309 by using fasteners to lock the second workpiece 600 on the rivet nut 30, thereby improving the assembly efficiency.

[0081] The rivet nut 30 is provided with a first chamfered structure 310 and a second chamfered structure 311. When the connecting portion 303 is assembled with the second workpiece 600, the locking section 309 can penetrate into the second through hole 601 of the second workpiece 600 along the first chamfered structure 310 and pass out of the second through hole 601 of the second workpiece 600 along the second chamfered structure 311.

[0082] The first chamfered structure 310 and the second chamfered structure 311 can guide the locking section 309 to pass into and out of the second through hole 601 , which is beneficial to improving assembly efficiency.

[0083] According to some embodiments of the present application, optionally, a first chamfer structure 310 is provided at one end of the locking section 309 away from the connecting section 308, and the first chamfer structure 310 is connected to the end of the first thread 307 away from the connecting section 308, or, a second chamfer structure 311 is provided at one end of the locking section 309 connected to the connecting section 308, and the second chamfer structure 311 is connected to the end of the first thread 307 close to the connecting section 308.

[0085] According to some embodiments of the present application, optionally, please refer to Figure 5 The rivet nut 30 is provided with a first opening 312 , which penetrates the end surface of the connecting portion 303 away from the rod portion 302 and extends toward the first end 304 , and the first thread 307 is provided on the hole wall of the first opening 312 .

[0086] The first thread 307 is an internal thread of the connection part 303, and can be conveniently connected with an external thread of a fastener such as a bolt or a screw. During assembly, the connection part 303 is located in the second through hole 601, and the fastener is inserted into the connection part 303 from the end of the connection part 303 away from the rod part 302, and the first thread 307 is connected with the external thread of the fastener, and the fastener is rotated to lock the second workpiece 600 on the connection part 303.

[0087] exist Figure 5 and Figure 7 In the figure, the end face of the connecting portion 303 away from the rod portion 302 is the bottom face of the connecting portion 303, and the bottom face of the connecting portion 303 does not protrude from the second through hole 601, that is, the bottom face of the connecting portion 303 is flush with the bottom opening of the second through hole 601, or the bottom face of the connecting portion 303 is located in the second through hole 601.

[0088] In one embodiment, the fastener (such as a bolt) includes a connecting rod and a head, and the circumferential side of the connecting rod is provided with an external thread. The head is connected to one end of the connecting rod, and the head protrudes from the connecting rod in the radial direction of the connecting rod. When the fastener is locking the second workpiece 600, from bottom to top, the connecting rod passes through the first opening 312 from the bottom end surface of the connecting portion 303, the first thread 307 is connected with the external thread of the fastener, and the fastener is rotated so that the head of the fastener is against the second workpiece 600 instead of against the connecting portion 303, so that the fastener can firmly lock the second workpiece 600 on the connecting portion 303.

[0089] According to some embodiments of the present application, optionally, please refer to Figure 4 and Figure 5 The rivet nut 30 is provided with a second opening 313 and a second thread 314 . The second opening 313 passes through the flange portion 301 and extends toward the second end 305 . The second thread 314 is provided on the hole wall of the second opening 313 .

[0090] Optionally, the second opening 313 may be a cylindrical hole, and the second thread 314 is an internal thread of the second opening 313 .

[0091] The second opening 313 extends through the flange 301 and into the rod 302. The diameter of the second opening 313 in the radial direction of the rivet nut 30 is smaller than the size of the rod 302. When the rivet nut 30 is used to lock the third workpiece (such as the socket of the connector), the fastener (such as a bolt or a screw, etc.) passes through the openings on the third workpiece and the second opening 313 in sequence and extends into the rod 302. The external thread on the fastener is connected to the second thread 314. The fastener is rotated so that the fastener locks the third workpiece on the rivet nut 30, thereby installing and fixing the third workpiece on the first workpiece 500 (such as the plug panel 40). Since the rivet nut 30 is used after riveting, the second opening 313 can also be used for the rivet tool to extend into the rod 302 to act on the rod 302 to deform the rod 302, thereby fixing the rivet nut 30 on the first workpiece 500.

[0092] According to some embodiments of the present application, optionally, in the axial direction of the rod portion 302 along the direction from the flange portion 301 to the connecting portion 303, the second opening 313 includes a first section 315 and a second section 316, the aperture of the first section 315 is larger than the aperture of the second section 316, and the second thread 314 is arranged on the hole wall of the second section 316.

[0093] Optionally, the first section 315 and the second section 316 may be cylindrical. The first section 315 penetrates the flange portion 301 and extends into the rod portion 302 , and the second section 316 is disposed in the rod portion 302 and connected to the first section 315 . The second thread 314 is an internal thread of the second section 316 .

[0094] The aperture of the first section 315 is larger than the aperture of the second section 316, that is, the wall thickness of the rod 302 at the position corresponding to the first section 315 is smaller than the wall thickness at the position corresponding to the second section 316. Since the first end 304 where the rod 302 is connected to the flange 301 may be deformed during the riveting process of the rivet nut 30, the wall thickness of the rod 302 at the position corresponding to the first section 315 is smaller, which can facilitate the rivet nut 30 to be riveted, thereby improving the usability of the rivet nut 30.

[0095] The second thread 314 is disposed on the hole wall of the second section 316 , and the wall thickness at the corresponding position of the rod 302 and the second section 316 is relatively large, which is beneficial to increase the connection strength between the rivet nut 30 and the fastener.

[0096] According to some embodiments of the present application, optionally, please refer to Figure 3 The flange portion 301 includes a first surface 317 facing away from the rod portion 302 and a second surface 318 facing the rod portion 302 , and the rivet nut 30 includes a plurality of ribs 319 , which are arranged at intervals and connect the second surface 318 and the rod portion 302 along the circumference of the rod portion 302 .

[0097] The second surface 318 of the flange portion 301 is a surface facing the rod portion 302, and thus connected to the circumferential side surface of the rod portion 302. The first surface 317 is a surface facing away from the rod portion 302. In this embodiment, the second opening 313 passes through the first surface 317.

[0098] The rivet nut 30 includes a plurality of ribs 319, which are arranged at intervals along the circumference of the rod 302 and connect the second surface 318 and the circumferential side of the rod 302. The ribs 319 can provide support between the flange 301 and the rod 302, and enhance the connection strength between the flange 301 and the rod 302. In addition, since the second surface 318 of the flange 301 is attached to the surface of the first workpiece 500 during the use of the rivet nut 30, after the rivet nut 30 is riveted, the ribs 319 can be embedded in the first workpiece 500, thereby preventing the rivet nut 30 from rotating under force, thereby increasing the fastening performance of the rivet nut 30.

[0099] According to some embodiments of the present application, optionally, please refer to Figure 3 A convex-concave structure 320 is provided on the circumferential side surface of the first end 304 .

[0100] The convexo-concave structure 320 may include protrusions and / or concave grooves 321. Figure 3 In the embodiment, the concave-convex structure includes a plurality of grooves 321 arranged on the circumferential side of the first end 304, the plurality of grooves 321 are arranged at intervals, the grooves 321 constitute the concave part of the concave-convex structure, and the rod portion 302 between two adjacent grooves 321 constitutes the convex part of the concave-convex structure 320. The present application does not specifically limit the number, shape and distribution of the grooves 321. Figure 3 In the embodiment, the groove 321 is in the shape of a strip, and the groove 321 extends along the axial direction of the rod 302. A plurality of grooves 321 are evenly spaced and arranged on the circumferential side surface of the first end 304 along the circumferential direction of the rod 302. The shape of each groove 321 can be the same or different, and the present application does not specifically limit this. Optionally, the groove 321 can also extend in other directions, so that a plurality of grooves 321 extend in the same direction, so as to provide a force in the same direction between the rivet nut 30 and the first workpiece 500, and the embodiment of the present application does not specifically limit this.

[0101] In other embodiments, the concave-convex structure may include a plurality of protrusions, the plurality of protrusions are convexly arranged on the circumferential side of the first end 304, the plurality of protrusions are arranged at intervals, the protrusions constitute the convex part of the concave-convex structure, and the rod portion 302 between two adjacent protrusions constitutes the concave part of the concave-convex structure 320. The present application does not specifically limit the number, shape, and distribution of the protrusions. The shape of each protrusion may be the same or different, and the present application does not specifically limit this.

[0102] In other embodiments, the concavo-convex structure may include a protrusion and a groove 321. The groove 321 is disposed on the circumferential side of the first end 304. The protrusion is disposed on the circumferential side of the first end 304, the groove 321 constitutes the concave part of the concavo-convex structure, and the protrusion constitutes the convex part of the concavo-convex structure.

[0103] Optionally, the length of the concavo-convex structure along the axial direction of the rod portion 302 is greater than the length of the first through hole 501 along the axial direction of the rod portion 302 , so as to ensure that the concavo-convex structure can cover the entire hole wall of the first through hole 501 .

[0104] During the use of the rivet nut 30, the rod 302 extends into the first through hole 501 of the first workpiece 500, and the first end 304 is at least partially located in the first through hole 501. During the rivet process of the rivet nut 30, the first end 304 may be deformed by rivet operation to fit into the hole wall of the first through hole 501, so that the rivet nut 30 is fixedly connected to the first workpiece 500. Therefore, in the case where the convex-concave structure is provided on the circumferential side surface of the first end 304, during the rivet deformation of the concave-convex structure at the first end 304, the convex part of the concave-convex structure may be embedded in the hole wall of the first through hole 501, and the hole wall of the first through hole 501 may be embedded in the concave part of the concave-convex structure, thereby preventing the rivet nut 30 from rotating under force, thereby further increasing the fastening performance of the rivet nut 30.

[0107] During the use of the rivet nut 30, the rod 302 passes through the first through hole 501 of the plug-in panel 40. The rod 302 forms a convex ring 306 during the riveting process. The convex ring 306 and the flange 301 clamp the plug-in panel 40, thereby riveting the rod 302 to the plug-in panel 40, thereby ensuring the connection strength between the plug-in panel 40 and the rivet nut 30.
