Description

Technical Field

[0001] The present application relates to the technical field of vehicle connection components, and in particular to an externally threaded fastener, a connection component, a controller fixing structure and a vehicle. Background Art

[0002] In the relevant technical field, as cars develop towards intelligence and networking, the number of vehicle-side controllers is increasing rapidly. These controllers need to face various extreme road conditions during vehicle operation and will be subjected to huge impacts from various control methods such as starting, braking, steering, and climbing during driving. The controller will be subjected to external forces from the longitudinal, lateral, and vertical directions, resulting in relative roll, pitch, and yaw movements. Therefore, a fastener with high connection strength and anti-loosening is needed to connect the controller to the vehicle body to increase the service life of the controller and reduce daily maintenance costs. Utility Model Content

[0003] The embodiments of the present application provide an externally threaded fastener, a connection assembly, a controller fixing structure and a vehicle, which have higher connection strength and an anti-loosening effect.

[0004] In a first aspect, an embodiment of the present application provides an externally threaded fastener, the externally threaded fastener comprising a threaded member and a glue storage member, the threaded member comprising a screw portion and a breaking portion, the screw portion comprising a screw head and a shaft connected to each other, the screw portion having a receiving cavity extending from the screw head to the shaft, the receiving cavity forming a filling port at an end face of the screw head away from the shaft and a glue outlet at a peripheral wall of the shaft; the breaking portion is in the receiving cavity and fixed to the shaft;

[0005] The glue storage piece has a glue storage cavity filled with liquid glue. The glue storage piece can be installed in the accommodating cavity through the filling port and squeeze the destroying part so that the destroying part destroys the glue storage piece.

[0006] Based on the externally threaded fastener of the embodiment of the present application, after the shaft of the externally threaded fastener passes through the connected component or is threadedly connected with the connected component, the glue storage piece is installed in the accommodating cavity through the filling port, the glue storage piece squeezes the breaking part to rupture the glue storage piece, and the liquid glue in the glue storage piece flows into the accommodating cavity under the action of gravity and flows into the pores between the shaft and the connected component through the glue outlet; in the process of the liquid glue gradually filling the pores between the shaft and the connected component, the oxygen in the pores prevents the liquid glue from solidifying to ensure that the liquid glue continues to flow along the pores to gradually fill the pores between the shaft and the connected component; when the air backlog in the pores is eliminated (that is, after the liquid glue fills the pores between the shaft and the connected component), the liquid glue is isolated from the air and solidified and rapidly polymerized at room temperature, and the liquid glue solidifies into a solid having the function of connecting the shaft and the connected component, thereby enhancing the connection strength and anti-loosening ability of the externally threaded fastener.

[0007] In some embodiments of the present application, the glue storage component includes a screw portion and an extrusion portion. After the glue storage component is installed in the accommodating cavity, the extrusion portion and the destruction portion are squeezed against each other, and the extrusion portion is at least partially configured as a brittle extrusion portion; the screw portion and the extrusion portion surround the glue storage cavity.

[0008] Based on the above embodiment, after the extrusion part that squeezes the breaking part is configured as a brittle extrusion part, the extrusion part is more likely to break when the extrusion part and the breaking part squeeze each other, and the opening formed after the extrusion part breaks is larger, so that the liquid glue in the glue storage cavity can quickly flow out of the glue storage part.

[0009] In some embodiments of the present application, after the glue storage member is installed in the accommodating chamber, the filling port coincides with the extrusion portion along the extension direction of the accommodating chamber.

[0010] Based on the above embodiments, it is ensured that when the glue storage member is installed into the accommodating cavity along the extension direction of the accommodating cavity, the breaking portion can be pressed against the pressing portion to ensure that the pressing portion is broken.

[0011] In some embodiments of the present application, the viscosity of the liquid glue is less than or equal to 55 mPa·s and greater than or equal to 5 mPa·s.

[0012] Based on the above embodiments, viscosity refers to the resistance of a fluid to flow. The greater the viscosity, the worse the fluidity of the fluid. The viscosity of the liquid glue is within this range, which ensures that the liquid glue has high fluidity to quickly fill the gap between the shaft and the connected component, but does not flow too fast and fail to fill the gap between the shaft and the connected component.

[0013] In some embodiments of the present application, the ratio of the length between the center position of the glue outlet along the axial direction of the threaded member and the end of the shaft connected to the screw head to the total length of the shaft is greater than or equal to 0.2 and less than or equal to 0.5.

[0014] Based on the above embodiment, the closer the glue outlet is to the screw head, the larger the volume of the gap between the rod shaft and the connected component that can be filled with liquid glue, that is, the larger the bonding area between the rod shaft and the connected component, the stronger the connection strength between the external threaded fastener and the connected component, but the volume of the accommodating cavity will be limited and thus limit the volume of the liquid glue; conversely, the farther the glue outlet is from the screw head, the smaller the volume of the gap between the rod shaft and the connected component that can be filled with liquid glue, that is, the smaller the bonding area between the rod shaft and the connected component, the lower the connection strength between the external threaded fastener and the connected component, but the volume of the accommodating cavity will increase and thus more liquid glue can be arranged; within this range, it can be ensured that the accommodating cavity can accommodate enough liquid glue and that the rod shaft and the connected component have a sufficiently large bonding area.

[0015] In some embodiments of the present application, there are multiple glue outlets, and the multiple glue outlets are evenly spaced along the circumference of the threaded rod.

[0016] Based on the above embodiment, multiple glue outlets can speed up the liquid glue to fill the gap between the shaft and the connected component. At the same time, multiple glue outlets are evenly spaced along the circumference of the shaft to ensure that the liquid glue can evenly fill the gap between the shaft and the connected component.

[0017] In a second aspect, an embodiment of the present application provides a connection assembly, including an internally threaded fastener and the externally threaded fastener as described above; the internally threaded fastener is threadedly connected to the shaft of the externally threaded fastener.

[0018] Based on the connection component in the embodiment of the present application, due to the above-mentioned external threaded fastener, the connection component can strengthen the connection strength between the connected components and prevent loosening.

[0019] In a third aspect, an embodiment of the present application provides a controller fixing structure, the controller fixing structure comprising a controller and an externally threaded fastener as described above, the externally threaded fastener being threadedly connected to the controller and an external fixing member, and the liquid glue being able to fill the gaps between the externally threaded fastener, the controller and the external fixing member and solidify after the glue storage member is broken; or,

[0020] The controller fixing structure includes a controller and a connecting assembly as described above, wherein the controller has a first connecting hole, the externally threaded fastener passes through the first connecting hole and the external fixing member and is fixedly connected to the internally threaded fastener, and after the glue storage member is broken, the liquid glue can fill the gap between the externally threaded fastener and the controller, the external fixing member and the internally threaded fastener and solidify.

[0021] Based on the controller fixing structure in the embodiment of the present application, due to the above-mentioned externally threaded fastener or connecting component, the connecting component or the externally threaded fastener can more firmly connect the controller and the external fixing member.

[0022] In a fourth aspect, an embodiment of the present application provides a vehicle, comprising a vehicle body and a controller fixing structure as described above, wherein the vehicle body has a second connecting hole; when the controller fixing structure only comprises an externally threaded fastener, the externally threaded fastener passes through the second connecting hole and is threadedly connected to the second connecting hole; when the controller fixing structure comprises a connecting assembly, the externally threaded fastener passes through the first connecting hole and the second connecting hole and is connected to the internally threaded fastener.

[0023] Based on the vehicle in the embodiment of the present application, due to the above-mentioned controller fixing structure, the connection strength between the vehicle body and the controller is higher, so as to reduce the maintenance of the connection relationship between the controller and the vehicle body.

[0024] Based on the externally threaded fastener, connecting component, controller fixing structure and vehicle of the embodiments of the present application, after the shaft of the externally threaded fastener passes through the connected component or is threadedly connected with the connected component, the glue storage part is installed in the accommodating cavity through the filling port, the glue storage part squeezes the breaking part to rupture the glue storage part, and the liquid glue in the glue storage part flows into the accommodating cavity under the action of gravity and flows into the pore between the shaft and the connected component through the glue outlet; in the process of the liquid glue gradually filling the pore between the shaft and the connected component, the oxygen in the pore prevents the liquid glue from solidifying to ensure that the liquid glue continues to flow along the pore to gradually fill the pore between the shaft and the connected component; when the air backlog in the pore is eliminated (that is, after the liquid glue fills the pore between the shaft and the connected component), the liquid glue is isolated from the air and solidified and rapidly polymerized at room temperature, and the liquid glue solidifies into a solid having the function of connecting the shaft and the connected component, thereby enhancing the connection strength and anti-loosening ability of the externally threaded fastener.

DETAILED DESCRIPTION

[0030] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0031] In the relevant technical field, as automobiles develop towards intelligence and networking, the number of vehicle-side controllers is increasing rapidly. These controllers need to face various extreme road conditions during vehicle operation and will be subjected to huge impacts from various control methods such as starting, braking, steering, and climbing during driving. The controller will be subjected to external forces from the longitudinal, lateral, and vertical directions, resulting in relative roll, pitch, and yaw movements. Therefore, a high-strength and anti-loosening external threaded fastener is needed to connect the controller to the vehicle body, so as to increase the service life of the controller and reduce daily maintenance costs.

[0032] To solve the above technical problems, please refer to Figures 1 to 3 As shown, the first aspect of the present application provides an external thread fastener 10, which has a higher connection strength and an anti-loosening effect.

[0033] Please refer to Figures 1 to 3 As shown, the external threaded fastener 10 includes a threaded member 11 and a glue storage member 12, the threaded member 11 includes a screw portion 111 and a breaking portion 112, the screw portion 111 has a accommodating cavity 1111, the accommodating cavity 1111 forms a filling port 1112 on one end face of the screw portion 111 and a glue outlet 1113 on the peripheral wall of the screw portion 111; the breaking portion 112 is in the accommodating cavity 1111 and is fixed to the screw portion 111; the glue storage member 12 has a glue storage cavity filled with liquid glue, the glue storage member 12 can be installed in the accommodating cavity 1111 through the filling port and squeeze the breaking portion 112 so that the breaking portion 112 destroys the glue storage member 12.

[0034] The external threaded fastener 10 in the embodiment of the present application can be a stud, for example, a single-headed stud or a double-headed stud, and the glue outlet 1113 can be formed on any end face of the stud. Since the liquid glue in the present application flows by gravity, during specific use, one end of the stud with the filling port 1112 should be located above the other end, and the user should try to expose the end of the stud with the filling port 1112 to the outside of the connected part when using the stud. The user installs the glue storage part 12 after connecting at least two connected parts through the stud or the cooperating internal threaded fastener 20.

[0035] The externally threaded fastener 10 in the embodiment of the present application may also be a bolt, for example, an external hexagonal bolt or an internal hexagonal bolt, etc. In this case, the screw portion 111 includes a screw head and a shaft connected to each other, and the loading port 1112 may be formed on the end face of the shaft away from the screw head, or may be formed on the end face of the shaft away from the screw head; however, since the screw head is usually exposed on the outside of the connected member, the loading port 1112 may be formed on the end face of the screw head away from the shaft, and the user may first fix at least two connected members by means of the externally threaded fastener 10 or the cooperating internally threaded fastener 20, and then install the glue storage member 12 into the accommodating cavity 1111, and the screw head should also be ensured to be above the shaft during use. During use, if the rod body must be above the screw head, and the filling port 1112 is formed on the end face of the rod body away from the screw head, for example, the threaded hole that cooperates with the bolt is a countersunk hole opening downward, then the glue storage part 12 is first installed in the accommodating cavity 1111, and the glue storage part 12 is pushed by the bottom wall of the threaded hole to cause the glue storage part 12 and the breaking part 112 to be squeezed.

[0036] The accommodating cavity 1111 is used to accommodate the destroyed glue storage member 12, that is, the accommodating cavity 1111 can only accommodate part of the glue storage member 12. In this way, the user can apply external force to the part of the glue storage member 12 outside the accommodating cavity 1111 to squeeze the glue storage member 12 and the destroying part 112 against each other. After the glue storage member 12 is destroyed, the destroyed glue storage member 12 can be completely in the accommodating cavity 1111. The shape of the accommodating cavity 1111 is not limited in the embodiment of the present application. Please refer to Figure 2 or Figure 3 As shown, in a specific embodiment of the present application, the accommodating chamber 1111 includes an accommodating sub-chamber and a glue outlet chamber, the accommodating sub-chamber is extended along the axial direction of the screw portion 111 and forms a filling port 1112 on one end face of the screw portion 111, the glue outlet chamber is extended along the radial direction of the screw portion 111 and forms a glue outlet 1113 on the peripheral wall of the screw portion 111, the destroying portion 112 is located in the glue outlet chamber and fixed to the chamber wall of the glue outlet chamber, and the accommodating sub-chamber and the glue outlet chamber are both configured as cylindrical cavities, then the corresponding filling port 1112 and glue outlet 1113 are both circular openings. It can be understood that the destroying portion 112 can also be in the glue outlet chamber and the accommodating sub-chamber at the same time.

[0037] The destroying portion 112 is used to destroy the glue storage member 12. In the embodiment of the present application, the shape, material and size of the destroying portion 112 are not limited. The size of the destroying portion 112 should ensure that the destroying portion 112 is within the accommodating cavity 1111. As for the material of the destroying portion 112, the destroying portion 112 can be made of the same material as the screw portion 111 and can be integrally formed. As for the shape of the destroying portion 112, in order to facilitate the destroying portion 112 to destroy the glue storage member 12; please refer to Figure 2 or Figure 3As shown, in some embodiments of the present application, the destroying portion 112 is configured as a conical structure, the cone tip of the destroying portion 112 is set toward the loading port 1112, and the cone bottom of the destroying portion 112 is connected to the rod body. It can be understood that according to the pressure formula P=F / S, the contact area between the glue storage part 12 and the cone tip base of the conical destroying portion 112 is smaller, and the greater the pressure applied by the destroying portion 112 to the glue storage part 12, the easier it is to destroy the glue storage part 12. At the same time, the conical destroying portion 112 can guide the liquid glue; wherein, P is pressure, the unit is Pa; F is pressure, the unit is N; S is the pressure area, the unit is m2.

[0038] Based on the externally threaded fastener 10 of the embodiment of the present application, after the shaft of the externally threaded fastener 10 passes through the connected component or is threadedly connected with the connected component, the glue storage part 12 is installed in the accommodating cavity 1111 through the filling port, and the glue storage part 12 squeezes the breaking part 112 to rupture the glue storage part 12. Under the action of gravity, the liquid glue in the glue storage part 12 flows into the accommodating cavity 1111 and flows into the pore between the shaft and the connected component through the glue outlet 1113; in the process of the liquid glue gradually filling the pore between the shaft and the connected component, the oxygen in the pore prevents the liquid glue from solidifying to ensure that the liquid glue continues to flow along the pore to gradually fill the pore between the shaft and the connected component. When the air backlog in the pore is eliminated (that is, after the liquid glue fills the pore between the shaft and the connected component), the liquid glue is isolated from the air and solidified and rapidly polymerized at room temperature. The liquid glue solidifies into a solid having the function of connecting the shaft and the connected component, thereby enhancing the connection strength and anti-loosening ability of the externally threaded fastener 10.

[0039] Please refer to Figure 2 As shown, in some embodiments of the present application, the glue storage component 12 includes a main body portion 121 and a brittle extrusion portion 122. After the glue storage component 12 is installed in the accommodating cavity 1111, the brittle extrusion portion 122 and the breaking portion 112 are squeezed against each other, and the screw portion 111 and the brittle extrusion portion 122 are arranged to form a glue storage cavity. When the brittle extrusion portion 122 and the breaking portion 112 are squeezed against each other, the brittle extrusion portion 122 is more likely to rupture, and an opening formed after the brittle extrusion portion 122 ruptures is larger (when the brittle material is compressed and ruptured, the entire brittle extrusion portion 122 may rupture), which can make the liquid glue in the glue storage cavity quickly flow out of the glue storage component 12.

[0040] It can be understood that the brittle extrusion portion 122 is made of a brittle material, and a brittle material refers to a material that only produces a small deformation, that is, it is destroyed and fractured under the action of an external force (such as stretching, impact, etc.). In combination with the above-mentioned accommodating sub-cavity being set as a cylindrical cavity, in some embodiments of the present application, the glue storage component 12 is set to be cylindrical, and after the glue storage component 12 is installed in the accommodating sub-cavity, the surrounding wall of the glue storage component 12 can fit the cavity wall of the accommodating sub-cavity, and any end face of the glue storage component 12 is set as the brittle extrusion portion 122. When the glue storage component 12 is installed in the accommodating cavity 1111, the brittle extrusion portion 122 of the glue storage component 12 first enters the accommodating cavity 1111 and then the glue storage component 12 is pushed into the accommodating cavity 1111 to cause mutual extrusion between the brittle extrusion portion 122 and the destructive portion 112.

[0041] In addition, to ensure that the brittle extrusion portion 122 can be broken, in some embodiments of the present application, the thickness of the brittle extrusion portion 122 is less than or equal to 1 mm, and the thickness of the main body 121 is less than or equal to 2 mm. Specifically, the brittle extrusion portion 122 is configured as a low borosilicate glass sheet, and the main body 121 is made of polypropylene, which has low cost, corrosion resistance and good chemical stability.

[0042] Please refer to Figure 2 or Figure 3 As shown, in some embodiments of the present application, after the glue storage piece 12 is installed in the accommodating cavity 1111, the filling port 1112 coincides with the breaking portion 112 and the brittle extrusion portion 122 along the extension direction of the accommodating cavity 1111. In this way, it is ensured that during the process of the glue storage piece 12 being installed in the accommodating cavity 1111 along the extension direction of the accommodating cavity 1111, the breaking portion 112 can be squeezed against the extrusion portion to ensure that the extrusion portion is broken.

[0043] In some embodiments of the present application, the viscosity of the liquid glue is less than or equal to 55 mPa·s and greater than or equal to 5 mPa·s. Viscosity refers to the resistance of a fluid to flow. The greater the viscosity, the worse the fluidity of the fluid. The viscosity of the liquid glue is within this range, which ensures that the liquid glue has high fluidity to quickly fill the gap between the screw portion 111 and the connected component, while not flowing too fast and failing to fill the gap between the shaft and the connected component.

[0044] In addition, in order to ensure the fluidity of the liquid glue in the pores between the screw portion 111 and the connected component, in some embodiments of the present application, the liquid glue is configured as anaerobic glue. Low-viscosity anaerobic glue can more easily penetrate the glue into very small thread gaps, which is beneficial to increase the contact area between the screw portion 111 and the connected component, thereby providing stronger connection strength.

[0045] It is understandable that, depending on the type of liquid glue, the liquid glue may have different effects after solidification. For example, if the liquid glue has insulating properties, it can improve the insulation between the connected parts; if the liquid glue has anti-corrosion properties, it can improve the corrosion resistance between the connected parts.

[0046] Please refer to Figure 2 or Figure 3 As shown, in some embodiments of the present application, the ratio of the length of the center position of the glue outlet 1113 along the axial direction of the threaded member 11 to the filling port 1112 to the total length of the rod is greater than or equal to 0.2 and less than or equal to 0.5. The closer the glue outlet 1113 is to the filling port 1112, the larger the volume of the pores between the rod and the connected component that can be filled with liquid glue, that is, the larger the bonding area between the screw portion 111 and the connected component, the stronger the connection strength between the external threaded fastener 10 and the connected component, but the volume of the accommodating cavity 1111 will be limited, thereby limiting the liquid. volume of liquid glue; on the contrary, the farther the glue outlet 1113 is from the filling port 1112, the smaller the volume of the gap between the screw part 111 and the connected component that can be filled with liquid glue, that is, the smaller the bonding area between the screw part 111 and the connected component, the lower the connection strength between the external threaded fastener 10 and the connected component, but the volume of the accommodating cavity 1111 will increase and more liquid glue can be arranged; within this range, it can be ensured that the accommodating cavity 1111 can accommodate enough liquid glue, and the screw part 111 and the connected component have a sufficiently large bonding area. In a specific embodiment of the present application, the ratio of the length of the glue outlet 1113 from the filling port 1112 to the total length of the screw part 111 is 0.3.

[0047] Please refer to Figure 2 or Figure 3 As shown, in some embodiments of the present application, there are multiple glue outlets 1113, and the multiple glue outlets 1113 are distributed at intervals along the circumference of the rod body. The multiple glue outlets 1113 can speed up the liquid glue to fill the pores between the rod body and the connected components. It can be understood that the multiple glue outlets 1113 can be distributed at intervals along the circumference of the rod body, so that the liquid glue can evenly fill the pores between the screw portion 111 and the connected components.

[0048] Second, please refer to Figure 1 As shown, an embodiment of the present application provides a connection assembly, including an internal threaded fastener 20 and the external threaded fastener 10 as described above; the internal threaded fastener 20 is threadedly connected to the threaded rod.

[0051] Third, please refer to Figure 1 As shown, an embodiment of the present application provides a controller fixing structure, which includes a controller 30 and an externally threaded fastener 10 as described above, wherein the externally threaded fastener 10 is threadedly connected to the controller 30 and the external fixing part, and after the glue storage part 12 is broken, the liquid glue can fill the gap between the externally threaded fastener 10 and the controller 30 and the external fixing part and solidify.

[0053] Based on the controller fixing structure in the embodiment of the present application, due to the above-mentioned externally threaded fastener 10, after the glue storage member 12 is broken, the liquid glue is filled into the gap between the externally threaded fastener 10 and the controller 30 and the external fixing part, and after the liquid glue solidifies, the externally threaded fastener 10 is bonded to the controller 30 and the external fixing part, so that the controller 30 can withstand a larger load, thereby extending the life of the controller 30 and reducing the number of maintenance operations on the controller 30, and the solidified liquid glue enhances the sealing between the externally threaded fastener 10 and the controller 30 and the external fixing part.

[0054] In other embodiments of the present application, the controller fixing structure includes a controller 30 and the above-mentioned connecting components, the external threaded fastener 10 passes through the controller 30 and the external fixing member and is fixedly connected to the internal threaded fastener 20, and after the glue storage member 12 is broken, the liquid glue can fill the gap between the external threaded fastener 10 and the controller 30, the external fixing member and the internal threaded fastener 20 and solidify.
