[0034] The hinge assembly and vehicle provided in this application will be described in detail below with reference to the accompanying drawings, through specific embodiments and application scenarios.
[0035] Please refer to Figures 1 to 7As shown in the embodiments of this application, a hinge assembly is provided for use in a vehicle. Optionally, the hinge assembly can be used as a door hinge to connect the door to the vehicle body (the vehicle body can specifically be the side panel of the vehicle body), the hinge assembly can also be used as a tailgate hinge to connect the tailgate to the vehicle body (the vehicle body can specifically be the roof of the vehicle body), and the hinge assembly can also be used as a hood hinge to connect the hood to the vehicle body (the vehicle body can specifically be the roof of the vehicle body). This application embodiment does not impose specific limitations on these aspects.
[0036] The following is a detailed description using a hinge assembly as an example of a car door hinge:
[0037] The hinge assembly includes a hinge 110 and a first connector 120. Optionally, the hinge 110 includes a first connecting structure, a pin, and a second connecting structure. The first connecting structure and the second connecting structure are rotatably connected by the pin. The first connecting structure is connected to the vehicle body 200, and the second connecting structure is connected to the vehicle door to realize the opening or closing of the vehicle door. The hinge 110 has a first connecting portion 111, specifically, the first connecting structure described above has a first connecting portion 111. The first connecting portion 111 is used to connect to the vehicle body 200 (hereinafter, the vehicle body 200 refers to the vehicle side panel). The first connector 120 is used to connect the first connecting portion 111 to the vehicle body 200. The first connecting portion 111 is used for a sealing fit with the outer surface of the vehicle body 200, and the first connecting portion 111 and the first connector 120 are in a sealing fit.
[0038] In this embodiment, the first connecting portion 111 of the hinge 110 is used to connect with the vehicle body 200, and the first connecting member 120 is used to connect the first connecting portion 111 of the hinge 110 to the vehicle body 200. The first connecting portion 111 is used to seal against the outer surface of the vehicle body 200 to seal the assembly gap between the hinge 110 and the vehicle body 200. The first connecting portion 111 and the first connecting member 120 are also sealed against each other to seal the assembly gap between the first connecting member 111 and the hinge 110. This improves the sealing performance of the hinge assembly, effectively preventing rainwater, dust, noise, etc., from entering the vehicle interior. This is beneficial for improving the vehicle's NVH performance and effectively protects the hinge assembly, preventing rust and corrosion and extending its service life. Therefore, this application can solve the problem of poor sealing performance of hinges in related technologies.
[0039] Optionally, the side of the first connecting part 111 facing the vehicle body 200 is designated as the first surface 111a. The first surface 111a can be fitted to the outer surface of the vehicle body 200 for sealing. However, this is a hard contact between the two, resulting in poor sealing performance. Alternatively, in other optional embodiments, the hinge assembly further includes a first sealing ring 130. The first sealing ring 130 surrounds the first connecting member 120 and is located within the assembly gap between the first connecting part 111 and the vehicle body 200. When the first sealing ring 130 is compressed by the first surface 111a and the outer surface of the vehicle body 200, it will deform to form an initial sealing force, thereby achieving self-tightening sealing. In this case, the first surface 111a and the outer surface of the vehicle body 200 make soft contact through the first sealing ring 130, thus achieving a sealing fit. This results in better sealing performance and can better prevent rainwater, dust, noise, and other external environmental factors from entering the vehicle interior.
[0040] Optionally, the first surface 111a is provided with a first annular groove 111a1, and a portion of the first sealing ring 130 is disposed within the first annular groove 111a1. The first sealing ring 130 is used for an interference fit with the outer surface of the vehicle body 200, so that the first connecting part 111 is sealed with the outer surface of the vehicle body 200 through the first sealing ring 130. In this solution, the sidewall of the first annular groove 111a1 can fix the first sealing ring 130, preventing the first sealing ring 130 from moving relative to the first surface 111a, thereby improving the stability of the first sealing ring 130. In addition, when a portion of the first sealing ring 130 is disposed within the first annular groove 111a1, this can reduce the additional space occupied by the first sealing ring 130 in the direction perpendicular to the first surface 111a.
[0041] In one optional embodiment, the side of the first connecting portion 111 facing away from the vehicle body 200 is the second surface 111b. The first connecting member 120 includes a threaded connecting rod 121 and a nut 122. The nut 122 is used to abut against the inner surface of the vehicle body 200, specifically the inner surface of the vehicle side panel. Optionally, a washer may be provided between the nut 122 and the inner surface of the vehicle body 200 to avoid direct contact between the nut 122 and the inner surface of the vehicle body 200, thereby protecting the vehicle body 200. The end of the connecting rod 121 away from the nut 122 is provided with a first annular flange 121a, which abuts against the second surface 111b. The first annular flange 121a and the second surface 111b can be sealed together by a sealing ring; alternatively, one of the first annular flange 121a and the second surface 111b is provided with a sealing groove 121a1, and the other is provided with a sealing protrusion 111b1. The sealing protrusion 111b1 and the sealing groove 121a1 are press-fitted together to make the first connecting part 111 and the first connecting member 120 seal together. This solution utilizes the structure of the first connecting member 120 and the hinge 110 itself to form a sealing structure, thereby preventing water stains, impurities, etc. from the external environment from entering the vehicle interior, thus reducing the number of parts in the hinge assembly. This not only facilitates the installation of the hinge assembly but also saves on the manufacturing cost of the hinge assembly.
[0042] Optionally, the sealing groove 121a1 can be disposed on the first annular flange 121a; or, in a further optional embodiment, the outer peripheral surface of the first annular flange 121a is provided with an annular extension 121b, the first part of the sealing groove 121a1 is disposed on the first annular flange 121a, and the second part of the sealing groove 121a1 is disposed on the annular extension 121b. This solution increases the contact area between the first connector 120 and the second surface 111b by providing the annular extension 121b on the outer peripheral surface of the first annular flange 121a, thereby improving the connection stability of the first connector 120; and, when the contact area between the first connector 120 and the second surface 111b is large, this facilitates the setting of the sealing groove 121a1. Of course, the sealing groove 121a1 can also be disposed on the second surface 111b.
[0043] Optionally, the first connector 120 and the wall of the through hole 111d of the first connecting part 111 can be fitted together for sealing. In this case, the two are in hard contact, and the sealing effect is not good. Alternatively, in another optional embodiment, the hinge assembly further includes a second sealing ring 140. The second sealing ring 140 is sleeved on the first connector 120 and is located in the assembly gap between the first connector 120 and the wall of the through hole 111d. When the second sealing ring 140 is in an interference fit with the first connector 120 and the wall of the through hole 111d, it will deform to form an initial sealing force, thereby achieving a self-tightening seal. At this time, the first connector 120 and the wall of the through hole 111d are in soft contact through the second sealing ring 140, thereby achieving a sealing fit. The sealing effect is better and can better prevent rainwater, dust, noise and other external environmental factors from entering the vehicle.
[0044] Optionally, the wall of the through hole 111d of the first connecting part 111 is provided with a second annular groove 111d1, and a portion of the second sealing ring 140 is disposed within the second annular groove 111d1. The second sealing ring 140 is press-fitted with the circumferential surface of the first connecting member 120 so that the first connecting member 120 is sealed with the first connecting part 111 through the second sealing ring 140. In this solution, the sidewall of the second annular groove 111d1 can fix the second sealing ring 140, preventing the second sealing ring 140 from axially moving relative to the wall of the through hole 111d, thereby improving the stability of the second sealing ring 140. In addition, when a portion of the second sealing ring 140 is disposed within the second annular groove 111d1, this can reduce the additional space occupied by the second sealing ring 140 within the through hole 111d.
[0045] Optionally, in an embodiment where the first connector 120 includes a threaded connecting rod 121 and a nut 122, the hinge assembly further includes a second sealing ring 140. The second sealing ring 140 is sleeved on the first connector 120. The wall of the through hole 111d of the first connecting portion 111 is provided with a second annular groove 111d1. A portion of the second sealing ring 140 is disposed in the second annular groove 111d1. The second sealing ring 140 is press-fitted with the circumferential surface of the first connector 120 so that the first connector 120 is sealed with the first connecting portion 111 through the second sealing ring 140. In this design, the sealing protrusion 111b1 and the sealing groove 121a1 are press-fitted to form a first sealing structure between the first connector 120 and the hinge 110. The second sealing ring 140 forms a second sealing structure between the first connector 120 and the hinge 110. The first sealing structure is used to prevent most rainwater, dust and other impurities from entering the vehicle. However, a small number of impurities will inevitably pass through the gap between the sealing protrusion 111b1 and the sealing groove 121a1 and come into contact with the second sealing structure. At this time, the second sealing ring 140 will prevent these impurities from entering the vehicle. This design improves the sealing performance of the hinge assembly by setting multiple sealing structures to prevent impurities from entering the vehicle.
[0046] In another optional embodiment, the hinge assembly further includes a third sealing ring 150, which is sleeved on the first connector 120. The third sealing ring 150 is used to seal against the circumferential surface of the first connector 120, the first connecting portion 111, and the wall of the first connecting hole 210 of the vehicle body 200. Since the first connecting portion 111 seals against the outer surface of the vehicle body 200 and the first connector 120, it initially prevents rainwater, dust, and other impurities from the external environment. When a small amount of impurities inevitably passes through the gaps between the first connecting portion 111 and the outer surface of the vehicle body 200, and between the first connecting portion 111 and the first connector 120, these impurities will come into contact with the third sealing ring 150. At this time, the third sealing ring 150 prevents these impurities from entering the vehicle interior, thereby further improving the sealing performance of the hinge assembly. Of course, the third sealing ring 150 may also be omitted.
[0047] Optionally, the third sealing ring 150 can be a sealing ring; or, in other optional embodiments, the third sealing ring 150 can be a sealant. The sealant can form a tight and continuous sealing layer to effectively prevent the penetration of water stains, dust and other impurities. It is also highly adaptable and can maintain a good sealing effect in high temperature, low temperature, humid or complex environments. In addition, the sealant can fix the first connector 120, thereby effectively preventing the first connector 120 from loosening.
[0048] The peripheral surface of the first connector 120 is used to form a first annular receiving cavity 160 with the hole wall of the first connecting hole 210 and the first connecting part 111. At least a portion of the third sealing ring 150 is disposed in the first annular receiving cavity 160. The first connector 120 is provided with a communicating annular receiving groove 123 and a first adhesive guiding channel 124. The annular receiving groove 123 is located in the first annular receiving cavity 160. The first end of the first adhesive guiding channel 124 is connected to the first annular receiving cavity 160 through the annular receiving groove 123. The second end of the first adhesive guiding channel 124 is connected to the external environment. When the first connector 120 is installed, glue is injected from the second end of the first glue channel 124. At this time, the glue flows along the first glue channel 124 to the first annular cavity 160 until the first annular cavity 160 is full. Then, the glue in the first annular cavity 160 is allowed to solidify to form the third sealing ring 150. During this process, the annular groove 123 has the function of collecting glue to prevent glue from flowing out of the gap between the first connector 120 and the first connecting hole 210. At the same time, the setting of the annular groove 123 can increase the thickness of the third sealing ring 150 to improve the adhesion and sealing stability of the sealant.
[0049] In another optional embodiment, the hinge assembly further includes a second connector 170 and a fourth sealing ring 180. The second connector 170 is spaced apart from the first connector 120. The first end of the second connector 170 passes through the second connecting hole 220 of the vehicle body 200 and is threadedly connected to the first connecting portion 111. The second end of the second connector 170 is provided with a second annular flange 171, which abuts against the inner surface of the vehicle body 200. By adding the second connector 170, the connection stability and firmness between the hinge 110 and the vehicle body 200 are improved. Of course, the second connector 170 can also be omitted.
[0050] Optionally, the side of the first connecting part 111 facing the vehicle body 200 is designated as the first surface 111a. The fourth sealing ring 180 is arranged around the second connecting member 170. The fourth sealing ring 180 is located within the assembly gap between the first connecting part 111 and the vehicle body 200. When the fourth sealing ring 180 is compressed by the first surface 111a and the outer surface of the vehicle body 200, it will deform to form an initial sealing force, thereby achieving a self-tightening seal. At this time, the first surface 111a and the outer surface of the vehicle body 200 make soft contact through the fourth sealing ring 180, thereby achieving a sealing fit. Its sealing effect is better, and it can better prevent rainwater, dust, noise, etc. from the external environment from entering the vehicle.
[0051] Optionally, the first surface 111a is further provided with a third annular groove 111e, and a portion of the fourth sealing ring 180 is located within the third annular groove 111e. The fourth sealing ring 180 is used for an interference fit with the outer surface of the vehicle body 200, so that the first connecting part 111 is sealed to the outer surface of the vehicle body 200 through the fourth sealing ring 180. In this solution, the sidewall of the third annular groove 111e can fix the fourth sealing ring 180, preventing the fourth sealing ring 180 from moving relative to the first surface 111a, thereby improving the stability of the fourth sealing ring 180. In addition, when a portion of the fourth sealing ring 180 is located within the third annular groove 111e, the additional space occupied by the fourth sealing ring 180 in the direction perpendicular to the first surface 111a can be reduced.
[0052] Optionally, the hinge assembly also includes a fifth sealing ring 190, which is sleeved on the second connector 170. The fifth sealing ring 190 can be a sealing ring or a sealant. The sealant can form a tight and continuous sealing layer to effectively prevent the penetration of water stains, dust and other impurities. It is also highly adaptable and can maintain a good sealing effect in high temperature, low temperature, humid or complex environments. In addition, the sealant can also fix the second connector 170, thereby effectively preventing the second connector 170 from loosening.
[0053] The circumferential surface of the second connector 170 is used to form a second annular receiving cavity 199 with the hole wall of the second connecting hole 220 and the first connecting portion 111. At least a portion of the fifth sealing ring 190 is disposed within the second annular receiving cavity 199. The second connector 170 is provided with a second adhesive guiding channel 172. The first end of the second adhesive guiding channel 172 is connected to the second annular receiving cavity 199, and the second end of the second adhesive guiding channel 172 is connected to the external environment. When the second connector 170 is installed, adhesive is injected from the second end of the second adhesive guiding channel 172. At this time, the adhesive flows along the second adhesive guiding channel 172 to the second annular receiving cavity 199 until the second annular receiving cavity 199 is full. Then, the adhesive in the second annular receiving cavity 199 is allowed to solidify to form the fifth sealing ring 190.
[0054] Optionally, the circumferential surface of the second connector 170 may be provided with an annular receiving groove. During the glue injection process, the annular receiving groove is used to collect the glue to prevent the glue from flowing out of the gap between the second connector 170 and the second connecting hole 220. At the same time, the setting of the annular receiving groove can increase the thickness of the fifth sealing ring 190 to improve the adhesion and sealing stability of the sealant.
[0055] Optionally, both the first adhesive channel 124 and the second adhesive channel 172 include a first adhesive guiding segment 124a and a second adhesive guiding segment 124b that are connected to each other. The first adhesive guiding segment 124a is connected to the external environment. The first adhesive guiding segment 124a of the first adhesive channel 124 is located on the end face of the first end of the first connector 120. The central axis of the first adhesive guiding segment 124a of the first adhesive channel 124 can be parallel to the central axis of the first connector 120. The second adhesive guiding segment 124b extends radially along the first connector 120 to the bottom of the annular receiving groove 123. The first adhesive guiding segment 124a of the second adhesive channel 172 is located on the end face of the second end of the second connector 170. The central axis of the first adhesive guiding segment 124a of the second adhesive channel 172 can be parallel to the central axis of the second connector 170. The second adhesive guiding segment 124b extends radially along the second connector 170 to the circumferential surface of the second connector 170.
[0056] Optionally, at least one of the first connector 120 and the second connector 170 may be a fastener such as a bolt, and this application embodiment does not impose specific limitations on this.
[0057] Optionally, at least one of the first sealing ring 130, the second sealing ring 140, and the fourth sealing ring 180 can be an O-ring, which has good sealing reliability. Of course, other types of sealing rings can also be used, and this application embodiment does not impose specific limitations on this.
[0058] Based on the hinge assembly provided in the embodiments of this application, this application also provides a vehicle, which includes a body 200, a door, and the hinge assembly described in any of the above embodiments. The hinge assembly is connected between the door and the body 200, and the door can rotate relative to the body 200 via the hinge assembly to switch between an open state and a closed state. This vehicle has the same beneficial effects as the hinge assembly described above, and will not be repeated here.
[0059] In an optional embodiment, the hinge assembly further includes a third sealing ring 150, which is sleeved on the first connector 120. The third sealing ring 150 is a sealant and includes a first annular sealing portion 151 and a second annular sealing portion 152 connected together. The circumferential surface of the first connector 120 is used to form a first annular receiving cavity 160 with the hole wall of the first connecting hole 210 of the vehicle body 200 and the first connecting portion 111. The first annular receiving cavity 160 includes a first annular cavity 161 and a second annular cavity 162 that are connected together. The first connector 120 is provided with a first adhesive guiding channel 124. The first end of the first adhesive guiding channel 124 is connected to the first annular receiving cavity 160, and the second end of the first adhesive guiding channel 124 is connected to the external environment. The vehicle body 200 includes an inner panel 230 and an outer panel 240 stacked together. The first connecting hole 210 includes a first hole segment 211 and a second hole segment 212 that are connected. The diameter of the first hole segment 211 is larger than the diameter of the second hole segment 212, that is, the first connecting hole 210 is a stepped hole. The first hole segment 211 is disposed on the outer panel 240. The hole wall of the first hole segment 211, the peripheral surface of the first connector 120 and the first connecting part 111 form a first annular cavity 161. The first annular sealing part 151 is disposed in the first annular cavity 161. The second hole segment 212 is disposed on the inner panel 230. The peripheral surface of the first connector 120 is provided with an annular receiving groove 123. The hole wall of the second hole segment 212 is opposite to the annular receiving groove 123 to form a second annular cavity 162. The second annular sealing part 152 is disposed in the second annular cavity 162. In this design, the first hole segment 211 and the second hole segment 212 of the first connecting hole 210 are differentiated. This can prevent the inner plate 230 and the outer plate 240 from being affected by manufacturing errors in the installation of the first connector 120. Furthermore, since the first connecting hole 210 is a stepped hole, the third sealing ring 150, which is correspondingly set in the first annular receiving cavity 160, is also a stepped structure. This can increase the contact area between the third sealing ring 150 and the vehicle body 200, thereby improving the sealing stability of the third sealing ring 150.
[0060] Optionally, the specific structure of the fifth sealing ring 190 and the specific structure of the second connecting hole 220 described above can be the same as or similar to the specific structure of the third sealing ring 150 and the specific structure of the first connecting hole 210 described above, so as to improve the sealing stability of the fifth sealing ring 190.
[0061] It should be noted that the type of vehicle is not limited in this application embodiment. Optionally, the vehicle can be a car, more specifically, such as an electric car, a fuel car or a hybrid electric car. The hinge assembly provided in this application embodiment can adapt to the design needs of different vehicle models and can be designed according to actual needs.
[0062] Optionally, the vehicle can be a sedan or a sports utility vehicle (i.e., an SUV), and this application embodiment does not impose specific limitations on this.
[0063] The embodiments of this application have been described above with reference to the accompanying drawings. However, this application is not limited to the specific embodiments described above. The specific embodiments described above are merely illustrative and not restrictive. Those skilled in the art can make many other forms under the guidance of this application without departing from the spirit and scope of the claims, and all of these forms are within the protection scope of this application.
