Description

Technical Field

[0001] This application relates to the field of vehicle body connector technology, and in particular to a hinge structure and a vehicle. Background Technology

[0002] Generally, car doors are connected to the car body via hinges to enable opening and closing. Due to the manufacturing processes involved in the production of car door sheet metal, body structure, and hinges, and the assembly tolerances between these three components, a certain gap is typically left between the hinges and the door to ensure proper installation.

[0003] However, water from outside the vehicle can easily enter the inside of the door through this gap. When the vehicle is in motion, the airflow passing through the gap will produce abnormal noise. Furthermore, the existence of the gap itself will also affect the overall appearance and refinement of the vehicle, ultimately impacting the overall user experience. Utility Model Content

[0004] In view of this, this application aims to propose a hinge structure to improve the overall user experience of the vehicle.

[0005] To achieve the above objectives, the technical solution of this application is implemented as follows: A hinge structure suitable for connecting a car door to a vehicle body, the hinge structure having a movable member disposed on the car door, a sealing assembly disposed on the movable member, and an anti-rotation part disposed between the movable member and the sealing assembly; The movable component has an outwardly extending connecting arm that is hinged to a fixed component on the vehicle body, and a gap is formed between the connecting arm and the door, with at least a portion of the sealing assembly filling the gap. The anti-rotation part is used to restrict the sealing assembly from rotating relative to the movable component.

[0006] Furthermore, the sealing assembly includes an elastic seal with a mounting hole and a gasket disposed in the mounting hole, the sealing assembly being connected to the movable member via a threaded member passing through the gasket; the anti-rotation part is disposed between the gasket and the movable member.

[0007] Furthermore, the anti-rotation part includes an anti-rotation groove on the washer and a protrusion on the movable member. The elastic seal has a relief groove communicating with the mounting hole. The protrusion extends into the mounting hole through the relief groove and is embedded in the anti-rotation groove.

[0008] Furthermore, the outer peripheral wall of the washer is provided with a groove, and the wall of the mounting hole is provided with a snap-fit ​​protrusion. The washer is snapped onto the snap-fit ​​protrusion through the groove; the anti-rotation groove extends through the groove along the axial direction of the washer.

[0009] Furthermore, the through hole on the washer through which the threaded part passes is an elongated hole, and the length direction of the through hole is the same as the outward extension direction of the connecting arm.

[0010] Furthermore, the elastic seal has a connecting portion and a sealing portion, the connecting portion being connected to the movable member, and the sealing portion filling the gap; the two opposite sides of the sealing portion interfere with the connecting arm and the door, respectively.

[0011] Furthermore, the sealing portion is provided with a first rib and a second rib at the end away from the connecting portion; the first rib and the second rib are respectively provided on two opposite sides of the sealing portion, and the first rib interferes with the connecting arm, and the second rib interferes with the door.

[0012] Furthermore, the interference between the first rib and the connecting arm is between 0.2mm and 0.8mm; and / or, the interference between the second rib and the door is between 0.5mm and 1.5mm.

[0013] Furthermore, the connecting arm has a protruding portion that protrudes outward from the door, and the gap is formed between the protruding portion and the door; the sealing portion is provided with an abutting protrusion that abuts against the protruding portion.

[0014] Compared with related technologies, this application has the following advantages: (1) The hinge structure described in this application, through the setting of the sealing component, can fill the gap between the connecting arm on the moving part and the door. It can not only fill the gap to ensure the delicate position of the door hinge arm and avoid the generation of abnormal noise caused by airflow through the gap, but also seal the gap between the moving part and the door. At the same time, the setting of the anti-rotation part can restrict the rotation of the sealing component to ensure the positional stability of the sealing component and ensure the sealing effect. This can effectively prevent external water from entering the inside of the door through the gap, thereby effectively preventing water from entering the door and improving the overall user experience of the vehicle.

[0015] (2) Connecting the elastic seal to the moving part with bolts provides good connection strength and facilitates the disassembly and maintenance of the elastic seal. Simultaneously, the use of washers allows the washers to withstand the pressure exerted on the elastic seal by the bolts, preventing deformation or damage due to excessive pressure. Furthermore, because the elastic seal has relatively low hardness, placing the bolts through the washers, compared to direct contact between the bolts and the elastic seal, also ensures the installation stability of the elastic seal.

[0016] (3) By the cooperation of the anti-rotation groove on the washer and the protrusion on the moving part, an interlocking structure can be formed to restrict the rotation of the washer relative to the moving part. At the same time, by setting the clearance groove on the elastic seal, the protrusion can be avoided, ensuring that the protrusion can be embedded in the anti-rotation groove, while avoiding the protrusion from squeezing or damaging the elastic seal.

[0017] (4) Through the matching of the slot and the snap-fit ​​protrusion, the gasket can snap-fit ​​with the elastic seal to ensure that the gasket can be kept in the mounting hole, so as to prevent the elastic seal from falling off the gasket and causing the connection between the elastic seal and the moving part to fail.

[0018] (5) By setting the through hole as an elongated hole and making the length direction of the through hole the same as the extension direction of the connecting arm, the elastic seal can move along the extension direction of the connecting arm, thereby providing a certain adjustment margin for the elastic seal, so as to adjust the installation position of the elastic seal according to the actual assembly situation, and improve the assembly accuracy and convenience.

[0019] (6) The connection part provides a mounting base for the gasket and the screw, so that the elastic seal can be installed on the moving part. At the same time, by setting the sealing part and making the sealing part interfere with the connecting arm and the door, the elastic deformation of the sealing part can be used to make the sealing part fit tightly against the door and the connecting arm to seal the gap between the door and the connecting arm, thereby ensuring the sealing effect.

[0020] (7) By setting the first rib and the second rib, the interference between the sealing part and the door and the connecting arm can be concentrated at the position of the first rib and the second rib, thereby reducing the contact area between the sealing part and the door and the connecting arm. Under the premise of ensuring the sealing effect, the wear of the sealing part is reduced, the service life of the sealing part is extended, and the long-term reliability of the hinge structure is improved.

[0021] (8) By limiting the amount of interference between the first rib and the connecting arm, and the amount of interference between the second rib and the door, the sealing effect is guaranteed while avoiding excessive pressure on the sealing part and causing it to bulge outward due to excessive interference. It also prevents the door from being deformed or the paint from being damaged due to excessive interference.

[0022] (9) By setting the protruding part, it is easy to realize the relative rotation between the moving part and the fixed part. At the same time, by setting the abutting protrusion, it can abut the protruding part and play a positioning role for the whole elastic seal, which can improve the setting stability and assembly efficiency of the elastic seal.

[0023] Another object of this application is to provide a vehicle having the hinge structure described above.

[0024] The vehicle described in this application and / or the hinge structure described above have the same technical effects as related technologies, and will not be described again here. Attached Figure Description

In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.

[0031] The present application will now be described in detail through exemplary embodiments. However, it should be understood that, without further description, elements, structures, and features in one embodiment may be advantageously incorporated into other embodiments.

[0032] An embodiment of the first aspect of this application provides a hinge structure.

[0033] In related technologies, due to the manufacturing processes involved in the production and processing of the door 3, body structure, and hinges, and the assembly tolerances between the door 3, body, and hinges, a certain gap is usually reserved between the hinge and the door 3. Especially for butterfly doors, water from outside the vehicle can easily enter the inside of the door 3 through this gap. When the door 3 is in motion, the airflow passing through the gap will produce abnormal noise, and the existence of the gap itself will also affect the overall appearance and refinement of the vehicle.

[0034] In view of this, in order to overcome the shortcomings of related technologies, the hinge structure of this embodiment combines... Figure 1 , Figure 2 As shown, the overall design includes a movable part 1 on the door 3, a sealing assembly on the movable part 1, and an anti-rotation part between the movable part 1 and the sealing assembly.

[0035] The movable part 1 has an extended connecting arm 101, which is hinged to the fixing part 2 on the vehicle body. A gap is formed between the connecting arm 101 and the door 3, and at least part of the sealing assembly is filled in the gap. The anti-rotation part is used to restrict the rotation of the sealing assembly relative to the movable part 1.

[0036] Therefore, by setting up the sealing component, it can fill the gap between the connecting arm 101 on the movable part 1 and the door 3. This not only fills the gap to ensure the smoothness of the door 3 hinge position and prevents abnormal noise caused by airflow through the gap, but also seals the gap between the movable part 1 and the door 3. Simultaneously, the anti-rotation part restricts the rotation of the sealing component, ensuring its positional stability and sealing effect. This effectively prevents external water from entering the inside of the door 3 through the gap, thus preventing water from entering the door 3 and improving the overall user experience.

[0037] Based on the above overall introduction, specifically, combined with Figure 2 , Figure 3 As shown, in this embodiment, the movable component 1 is installed on the sheet metal of the car door 3. The connecting arm 101 of the movable component 1 has a connecting structure 102 at one end facing the car door 3. The connecting structure 102 extends laterally, and through holes 103 for fasteners such as bolts and rivets are provided on opposite sides of the connecting structure 102. The sheet metal of the car door 3 has an installation portion 301 extending towards the inside of the vehicle. The installation portion 301 has an assembly hole corresponding to the through hole 103. Fasteners can pass through the through hole 103 of the connecting structure 102 and be connected in the assembly hole, thereby realizing the connection and fixation between the movable component 1 and the car door 3.

[0038] Furthermore, similar to related technologies, such as Figure 2 As shown, the fastener 2 in this embodiment also includes a mounting base 201 for connecting to the vehicle body, and a hinge end 202 provided on the mounting base 201. A hinge groove is formed on the connecting arm 101 of the movable member 1. The hinge end 202 of the fastener 2 is located in the hinge groove and is hingedly connected to the side wall of the hinge groove. Meanwhile, the mounting base 201 extends along the rotation axis of the hinge structure, and the mounting base 201 has fixing holes 2011 for fasteners such as bolts and rivets to pass through at two opposite sides of the hinge end 202. The vehicle body has mounting holes at positions corresponding to the fixing holes 2011, and fasteners can pass through the fixing holes 2011 and be connected in the mounting holes to install the fastener 2 on the vehicle body.

[0039] In addition, in this embodiment, a decorative panel 7 is provided on the vehicle body corresponding to the aforementioned fastener 2. The decorative panel 7 can cover the fastener 2 and prevent the fastener 2 from being exposed. This not only ensures the exquisite appearance of the vehicle, but also protects the fastener 2 to prevent it from being exposed on the outside of the vehicle body and being damaged.

[0040] Combination Figure 8 , Figure 11As shown, in some exemplary embodiments, the sealing assembly includes a resilient seal 4 having a mounting hole 4011 and a gasket 5 disposed in the mounting hole 4011. The sealing assembly is connected to the movable member 1 via a threaded member 6 passing through the gasket 5. An anti-rotation portion is disposed between the gasket 5 and the movable member 1.

[0041] The elastic seal 4 is connected to the movable part 1 via the threaded part 6, providing good connection strength and facilitating the disassembly and maintenance of the elastic seal 4. Simultaneously, the washer 5 can withstand the pressure exerted on the elastic seal 4 by the threaded part 6, preventing deformation or damage due to excessive pressure. Furthermore, because the elastic seal 4 has relatively low hardness, threading the threaded part 6 through the washer 5, compared to direct contact between the threaded part 6 and the elastic seal 4, also ensures the installation stability of the elastic seal 4.

[0042] In practical implementation, the elastic seal 4 in this embodiment can be made of thermoplastic vulcanized rubber (TPV), which has good elasticity and can ensure the sealing between the door 3 and the connecting arm 101 by utilizing its own elastic deformation. At the same time, the elastic seal 4 has good durability, so that the elastic seal 4 exposed on the outside of the vehicle has a long service life.

[0043] Meanwhile, in this embodiment, the gasket 5 can be made of plastic, which ensures sufficient structural strength while effectively reducing wear between the gasket 5 and the connecting arm 101, as well as between the gasket 5 and the elastic seal 4. Of course, the elastic seal 4 and the gasket 5 can also be made of other materials well known to those skilled in the art, as long as the sealing effect of the elastic seal 4 and the structural strength of the gasket 5 are guaranteed.

[0044] Combination Figure 9 , Figure 12 and Figure 14 As shown, in some exemplary embodiments, the anti-rotation part includes an anti-rotation groove 501 provided on the washer 5 and a protrusion 1011 provided on the movable member 1. The elastic seal 4 is provided with a relief groove 4012 communicating with the mounting hole 4011. The protrusion 1011 extends into the mounting hole 4011 via the relief groove 4012, and the protrusion 1011 is embedded in the anti-rotation groove 501.

[0045] Understandably, the head of the threaded part 6 is pressed tightly against the top of the washer 5. During the tightening process of the threaded part 6, the threaded part 6 is driven to rotate, so that the head of the threaded part 6 can drive the washer 5 to rotate, causing relative rotation between the washer 5 and the moving part 1, causing the elastic seal 4 to deflect on the moving part 1.

[0046] By engaging the anti-rotation groove 501 on the washer 5 with the protrusion 1011 on the movable part 1, a fitting structure is formed to restrict the rotation of the washer 5 relative to the movable part 1, preventing the elastic seal 4 from deflecting and ensuring the sealing effect of the elastic seal 4. Simultaneously, by providing a clearance groove 4012 on the elastic seal 4, the protrusion 1011 is avoided, ensuring that the protrusion 1011 can be embedded in the anti-rotation groove 501, while preventing the protrusion 1011 from squeezing or damaging the elastic seal 4.

[0047] In specific implementation, the extension directions of the protrusion 1011, the clearance groove 4012 and the anti-rotation groove 501 in this embodiment are all consistent with the outward extension direction of the connecting arm 101 of the movable member 1. By utilizing the space in the outward extension direction of the connecting arm 101, the length of the protrusion 1011 is increased, thereby ensuring the limiting effect of the protrusion 1011 on the anti-rotation groove 501, and ultimately ensuring the anti-rotation effect of the elastic seal 4.

[0048] Combination Figure 6 , Figure 11 and Figure 14 As shown, in some exemplary embodiments, the outer peripheral wall of the washer 5 is provided with a groove 502, and the wall of the mounting hole 4011 is provided with a snap-fit ​​protrusion 4013. The washer 5 is snapped onto the snap-fit ​​protrusion 4013 through the groove 502. The anti-rotation groove 501 extends through the groove 502 along the axial direction of the washer 5.

[0049] Through the cooperation of the slot 502 and the snap-fit ​​protrusion 4013, the gasket 5 can be snapped into the elastic seal 4, ensuring that the gasket 5 can be kept in the mounting hole 4011, so as to prevent the elastic seal 4 from falling off the gasket 5 and causing the connection between the elastic seal 4 and the moving part 1 to fail.

[0050] Meanwhile, the anti-rotation groove 501 is set through the slot 502, which further increases the depth of the anti-rotation groove 501, thereby increasing the size of the protrusion 1011 in the axial direction of the gasket 5, further improving the limiting effect of the protrusion 1011 on the gasket 5 and the elastic seal 4, so as to prevent the sealing assembly from rotating.

[0051] In specific implementation, the snap-fit ​​protrusion 4013 of this embodiment is located on the hole wall of the mounting hole 4011 on the side away from the anti-rotation groove 501, so as to snap-fit ​​and fix the washer 5 on the other side where the anti-rotation groove 501 is not provided.

[0052] Combination Figure 9 , Figure 13 As shown, in some exemplary embodiments, the through hole 503 on the washer 5 for the threaded part 6 to pass through is an elongated hole, and the length direction of the through hole 503 is the same as the outward extension direction of the connecting arm 101.

[0053] By setting the through hole 503 as an elongated hole and making the length direction of the through hole 503 the same as the extension direction of the connecting arm 101, when the threaded part 6 passes through the through hole 503 of the washer 5, the washer 5 can move along the length direction of the through hole 503 through the through hole 503, thereby driving the elastic seal 4 to move along the extension direction of the connecting arm 101, thus providing a certain adjustment margin for the elastic seal 4, so as to adjust the installation position of the elastic seal 4 according to the actual assembly situation, and improve the assembly accuracy and convenience.

[0054] In specific implementation, the length dimension 'a' of the through hole 503 in this embodiment can be selected as 6mm, and the width dimension 'b' can be selected as 4mm. By limiting the size of the through hole 503, the elastic seal 4 has a certain adjustment margin in both the length and width directions of the through hole 503, further facilitating the assembly operation of the elastic seal 4. Furthermore, by limiting the size of the through hole 503, friction between the threaded part 6 and the hole wall of the through hole 503 can be reduced during the tightening process of the threaded part 6, preventing damage to the washer 5. Of course, other dimensions can also be selected for the through hole 503 in this embodiment, as long as sufficient adjustment margin is provided for the elastic seal 4 in both the length and width directions of the through hole 503.

[0055] Combination Figure 5 , Figure 10 As shown, in some exemplary embodiments, the resilient seal 4 has a connecting portion 401 and a sealing portion 402, the connecting portion 401 being connected to the movable member 1, and the sealing portion 402 filling the gap. The two opposite sides of the sealing portion 402 interfere with the connecting arm 101 and the door 3, respectively.

[0056] The connection portion 401 provides a mounting base for the gasket 5 and the threaded part 6, facilitating the installation of the elastic seal 4 onto the movable part 1. Simultaneously, by providing the sealing portion 402 and allowing it to interfere with the connecting arm 101 and the door 3, the elastic deformation of the sealing portion 402 allows it to tightly fit against the door 3 and the connecting arm 101, sealing the gap between them and ensuring a proper seal.

[0057] In a specific implementation, the sealing portion 402 of this embodiment is located at the end of the connecting portion 401 away from the door 3, and the sealing portion 402 is formed by extending the connecting portion 401 outward from the vehicle. The connecting portion 401 of this embodiment is located between the sheet metal of the door 3 and the connecting arm 101 of the movable part 1, and can be covered by the sheet metal of the door 3, so as to make full use of the space between the door 3 and the connecting arm 101, making the overall structure of the door 3 more compact.

[0058] Furthermore, in this embodiment, the sealing portion 402 facing the connecting portion 401 has a curved surface structure at the junction with the top of the connecting portion 401. Through the design of the curved surface structure, a smooth transition between the sealing portion 402 and the connecting portion 401 is achieved, so as to avoid sharp turns at the junction of the sealing portion 402 and the connecting portion 401. This can effectively disperse the local stress when the sealing portion 402 deforms, and prevent the elastic seal 4 from cracking and aging due to stress concentration during long-term use, thereby improving the service life of the elastic seal 4.

[0059] Combination Figure 7 , Figure 10 As shown, in some exemplary embodiments, the sealing portion 402 is provided with a first rib 4021 and a second rib 4022 at the end away from the connecting portion 401, that is, at the top of the sealing portion 402. The first rib 4021 and the second rib 4022 are respectively provided on two opposite sides of the sealing portion 402, and the first rib 4021 interferes with the connecting arm 101, and the second rib 4022 interferes with the door 3.

[0060] By setting the first rib 4021 and the second rib 4022, the interference between the sealing part 402 and the door 3 and the connecting arm 101 can be concentrated at the positions of the first rib 4021 and the second rib 4022, thereby reducing the overall contact area between the sealing part 402 and the door 3 and the connecting arm 101. While ensuring the sealing effect, this reduces the wear of the sealing part 402, extends the service life of the sealing part 402, and improves the long-term reliability of the hinge structure.

[0061] Specifically, in combination Figure 7 As shown, in some exemplary embodiments, the interference amount L1 between the first rib 4021 and the connecting arm 101 is between 0.2mm and 0.8mm, while in another embodiment, the interference amount L2 between the second rib 4022 and the door 3 is between 0.5mm and 1.5mm.

[0062] Understandably, if the interference between the rib and the corresponding door 3 or connecting arm 101 is too small, the pressure between the rib and the door 3 or connecting arm 101 will be small, the sealing part 402 will have a poor contact effect, and there will be small gaps between the sealing part 402 and the door 3 or connecting arm 101. External water will easily leak into the inside of the door 3 due to capillary effect, and the problem of water entering the door 3 will still exist.

[0063] When the interference between the rib and the corresponding door 3 or connecting arm 101 is too large, the sealing part 402 exerts a large pressure on the door 3 and connecting arm 101, and the sealing part 402 will undergo excessive deformation.

[0064] On the one hand, it may cause the sheet metal of the car door 3 to deform due to excessive pressure, or damage the paint on the sheet metal of the car door 3. On the other hand, it may also cause abnormal friction or jamming between the sealing part 402 and the car door 3 and the connecting arm 101, resulting in abnormal noise and affecting the user experience of the car door 3.

[0065] On the other hand, the deformation of the sealing part 402 will cause the internal stress of the sealing part 402 to continuously exceed the design stress, thereby accelerating the material aging, cracking or elastic failure of the sealing part 402 of the elastic seal 4, affecting the service life of the elastic seal 4, and ultimately causing the sealing part 402 to fail to continuously fit the door 3 or connecting arm 101 and thus fail to seal.

[0066] Therefore, by limiting the interference between the first rib 4021 and the connecting arm 101, and the interference between the second rib 4022 and the door 3 within the above-mentioned size range, it is possible to ensure the sealing effect while avoiding excessive pressure on the sealing part 402 and causing it to bulge outward due to excessive interference, and to prevent the door 3 from being deformed or its paint surface from being damaged due to excessive interference.

[0067] In specific implementation, the interference amount L1 between the first protruding rib 4021 and the connecting arm 101 in this embodiment can be selected as 0.2mm, 0.4mm, 0.6mm, or 0.8mm, and the interference amount L2 between the second protruding rib 4022 and the door 3 can be selected as 0.5mm, 1mm, or 1.5mm. Furthermore, when selecting the interference amounts L1 and L2, it is preferable to set L1 < L2.

[0068] It is understandable that the connecting arm 101 of the movable part 1 is a rigid structure, and the elastic seal 4 is installed on the connecting arm 101. The distance between the sealing part 402 and the abutting area of ​​the first protruding rib 4021 on the connecting arm 101 will not change significantly. Therefore, the first protruding rib 4021 and the connecting arm 101 only need to maintain a small amount of interference to ensure that the first protruding rib 4021 can fit tightly against the connecting arm 101, thereby ensuring the sealing effect between the sealing part 402 and the connecting arm 101.

[0069] The door 3 is assembled to the connecting structure 102 of the moving part 1 by fasteners, and there is a certain assembly tolerance between the door 3 and the moving part 1. Furthermore, during vehicle operation, the door 3 is prone to swaying and shifting relative to the moving part 1 due to vibration, and the sheet metal of the door 3 is also prone to deformation due to temperature, resulting in a significant change in the distance between the sealing part 402 and the abutment area of ​​the second rib 4022 on the door 3.

[0070] Therefore, by setting a larger interference amount between the second rib 4022 and the door 3, the assembly tolerance of the door 3 and the deformation of the door 3 itself can be compensated, thereby further improving the sealing effect between the door 3 and the sealing part 402.

[0071] Combination Figure 7 , Figure 10 As shown, in some exemplary embodiments, the connecting arm 101 has a protruding portion 1012 that protrudes outward from the door 3, forming a gap between the protruding portion 1012 and the door 3. The sealing portion 402 is provided with an abutting protrusion 4023 that abuts against the protruding portion 1012.

[0072] By providing the protruding portion 1012, relative rotation between the movable part 1 and the fixed part 2 is facilitated. At the same time, by providing the abutting protrusion 4023, the protruding portion 1012 can be abutted, which can play a positioning role for the entire elastic seal 4, thereby improving the installation stability and assembly efficiency of the elastic seal 4.

[0073] Meanwhile, the protruding part 1012, as a rigid structure on the connecting arm 101, can support the sealing part 402 to ensure that the sealing part 402 fits tightly with the sheet metal of the door 3.

[0074] In a specific implementation, the abutment protrusion 4023 of this embodiment can be configured as a rib-like structure, and the extending direction of the abutment protrusion 4023 is consistent with the length direction of the first rib 4021, so that the abutment protrusion 4023 and the first rib 4021 form a double seal between the sealing portion 402 and the protruding portion 1012, further improving the sealing performance between the connecting arm 101 and the elastic seal 4. Furthermore, a semi-circular abutment surface is formed on one side of the abutment protrusion 4023 that abuts against the connecting arm 101, and the radius r of the semi-circular abutment surface can be selected as 1 mm.

[0075] It should be noted that, in addition to being a rib-like structure, the abutting protrusion 4023 can also be a column-like structure. In this case, in order to improve the positioning effect, the abutting protrusion 4023 can be set as multiple protrusions spaced apart.

[0076] Furthermore, in this embodiment, the protruding portion 1012 extends outwards from the vehicle and is exposed on the outer side of the vehicle body. Simultaneously, the decorative panel 7 in this embodiment has a clearance groove 4012 for avoiding the protruding portion 1012, and the protruding portion 1012 is filled within the clearance groove 4012. The clearance groove 4012 ensures that the decorative panel 7 can avoid interference between the decorative panel 7 and the connecting arm 101 of the movable component 1 when the door 3 is opened, thus preventing interference between the decorative panel 7 and the connecting arm 101 of the movable component 1.

[0077] In addition, combined Figure 3 , Figure 4As shown, the decorative panel 7 is provided with a sealing strip 8, which fills the gap between the decorative panel 7 and the door 3 and the protrusion 1012 to ensure the sealing between the decorative panel 7 and the door 3, and between the decorative panel 7 and the protrusion 1012, and further prevent water from entering the door 3.

[0078] It is worth noting that, regarding the hinge structure of this embodiment, based on the above exemplary implementations, in specific implementation, as a preferred embodiment, it is still composed of... Figures 1 to 14 As shown, it may include, for example, a movable member 1 provided on the door 3, a sealing assembly provided on the movable member 1, and an anti-rotation part provided between the movable member 1 and the sealing assembly.

[0079] The movable component 1 has an extended connecting arm 101, which is hinged to a fixed component 2 mounted on the vehicle body, and a gap is formed between the connecting arm 101 and the door 3. The sealing assembly includes an elastic seal 4 with a mounting hole 4011 and a washer 5 disposed in the mounting hole 4011. The sealing assembly is connected to the movable component 1 via a threaded member 6 passing through the washer 5. The sealing portion 402 fills the gap and interferes with both the connecting arm 101 and the door 3. An anti-rotation part is disposed between the washer 5 and the movable component 1 to restrict rotation of the sealing assembly relative to the movable component 1.

[0080] Furthermore, the anti-rotation part includes an anti-rotation groove 501 on the washer 5 and a protrusion 1011 on the movable member 1. The elastic seal 4 has a relief groove 4012 communicating with the mounting hole 4011. The protrusion 1011 extends into the mounting hole 4011 through the relief groove 4012 and is embedded in the anti-rotation groove 501. The outer peripheral wall of the washer 5 has a retaining groove 502, and the wall of the mounting hole 4011 has a retaining protrusion 4013. The washer 5 is retained on the retaining protrusion 4013 through the retaining groove 502. The anti-rotation groove 501 extends through the retaining groove 502 along the axial direction of the washer 5. The washer 5 has an elongated hole through which the threaded member 6 passes and extends along the outward extension direction of the connecting arm 101.

[0081] Meanwhile, the sealing portion 402, at the end furthest from the connecting portion 401, is provided with a first rib 4021 and a second rib 4022. The first rib 4021 and the second rib 4022 are respectively provided on two opposite sides of the sealing portion 402, and the first rib 4021 interferes with the connecting arm 101, while the second rib 4022 interferes with the door 3. The connecting arm 101 has a protruding portion 1012 that protrudes outward from the door 3, forming a gap between the protruding portion 1012 and the door 3. The sealing portion 402 is provided with an abutting protrusion 4023, which abuts against the protruding portion 1012.

[0082] In the preferred embodiment of the hinge structure above, the specific settings and arrangements of the movable part 1, the fixed part 2, the sealing component, etc. can still be referred to the descriptions in the above exemplary embodiments. Furthermore, in this preferred embodiment, the beneficial effects brought about by the design of the movable part 1, the fixed part 2, the sealing component, etc. can also be referred to the descriptions in the above exemplary embodiments.

[0083] The hinge structure of this embodiment adopts the design described above. Through the setting of the sealing component, the sealing component can fill the gap between the connecting arm 101 on the movable part 1 and the door 3. This not only fills the gap to ensure the refined appearance of the hinge arm position of the door 3, but also prevents abnormal noise caused by airflow through the gap. Simultaneously, the anti-rotation part restricts the rotation of the sealing component to ensure its positional stability and sealing effect. This effectively prevents external water from entering the inside of the door 3 through the gap, thus effectively avoiding water ingress into the door 3 and improving the overall user experience of the vehicle.
