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] Currently, in some vehicle models, the hinge structure connecting the door to the body is often directly exposed on the outside of the vehicle. Generally, considering the manufacturing tolerances of the door sheet metal and hinge structure, and the assembly tolerances of the door and hinge connection, a certain gap is usually left between the door and the hinge structure to ensure proper installation. However, because of this gap, water from outside the vehicle can easily enter the inside of the door, causing water ingress and affecting the overall user experience. Utility Model Content

[0003] In view of this, this application aims to propose a hinge structure to prevent water from entering the vehicle door.

[0004] To achieve the above objectives, the technical solution of this application is implemented as follows:

[0005] A hinge structure suitable for connecting a vehicle door to a vehicle body, the hinge structure having a movable part disposed on the vehicle door and an elastic seal disposed on the movable part;

[0006] The movable component has an outwardly extending hinge arm, which is hingedly connected to a fixed component on the vehicle body, and a gap is formed between the hinge arm and the door.

[0007] The elastic seal has a connecting portion and a sealing portion, the connecting portion being connected to the movable part, and the sealing portion filling the gap.

[0008] Furthermore, one side of the sealing portion abuts against the hinge arm, while the other side of the sealing portion interferes with the door.

[0009] Furthermore, the width of the gap is between 4.0mm and 5.0mm; and / or, the interference between the sealing part and the door is not less than 0.8mm.

[0010] Furthermore, the sealing portion is provided with a protrusion protruding towards one side of the car door, and a recess located at the root of the protrusion; the protrusion interferes with the car door, and the recess is used to avoid the car door.

[0011] Furthermore, the connecting portion is located between the movable member and the door, and the sealing portion is connected to one end of the connecting portion; the hinge arm has a protruding portion that protrudes outward toward the door, and the sealing portion abuts against the protruding portion.

[0012] Furthermore, the connecting portion is provided with a mounting hole and a rigid washer disposed in the mounting hole; the connecting portion is connected to the movable part by a screw threaded through the washer.

[0013] Furthermore, the outer peripheral wall of the gasket is provided with a groove, and the wall of the mounting hole is provided with a retaining ring; the gasket is engaged in the mounting hole through the groove and the retaining ring.

[0014] Furthermore, the sealing portion is provided with an abutting protrusion, which abuts against the movable part.

[0015] Compared with related technologies, this application has the following advantages:

[0016] (1) The hinge structure described in this application, through the setting of the elastic seal, the sealing part of the elastic seal can fill the gap between the hinge arm and the door, which can not only ensure the exquisiteness of the door hinge arm position, but also seal the gap between the hinge arm and the door, effectively preventing external water from entering the inside of the door through the gap between the hinge arm and the door, thereby effectively avoiding the occurrence of water entering the door, and thus improving the overall user experience of the vehicle.

[0017] (2) By interfering with the door, the elastic deformation of the sealing part can be used to make the sealing part fit tightly against the door, thereby sealing the gap between the door and the sealing part. At the same time, the sealing part abuts against the hinge arm, which not only ensures the sealing effect between the sealing part and the hinge arm, but also allows the hinge arm to support the sealing part, ensuring that the sealing part can apply sufficient pressure to the door, further facilitating the tight fit between the sealing part and the door, thereby ensuring the sealing performance between the door and the hinge arm.

[0018] (3) By limiting the width of the gap, sufficient clearance can be ensured between the door and the hinge arm to avoid interference between the hinge arm and the door sheet metal caused by manufacturing and assembly tolerances of the door and hinge arm, and to provide sufficient installation space for the elastic seal. In addition, by limiting the amount of interference between the sealing part and the door, not only can the tight fit between the sealing part and the door be ensured, thus guaranteeing the sealing effect, but it can also prevent the sealing part from being excessively squeezed and bulging outward due to excessive interference, which would affect the flatness of the door hinge structure, or prevent excessive pressure on the door due to excessive interference, which would cause deformation of the door structure or damage to the door paint.

[0019] (4) Through the combination of the protrusion and the recess, the recess can provide sufficient elastic deformation space for the protrusion, so that when the protrusion interferes with the door, it can deform fully under the action of pressure, thereby ensuring the tight fit between the protrusion and the door, and increasing the contact area between the protrusion and the door to a certain extent, so as to improve the sealing performance. At the same time, the recess can prevent other areas of the sealing part from contacting the door, and prevent the sealing part from interfering too much with the door, which would affect the elastic seal, that is, the assembly of the hinge structure and the door.

[0020] (5) By placing the connecting part between the movable part and the door and connecting it to one side of the sealing part, it is possible to prevent the connecting part from affecting the arrangement of the sealing part at the gap and to facilitate the assembly and connection of the elastic seal and the movable part. Furthermore, by setting the protruding part, the contact area between the hinge arm and the elastic seal is increased. At the same time, the protruding part can abut against the sealing part, forming a support for the sealing part, ensuring the pressure applied by the sealing component to the door, and ensuring the sealing effect between the sealing part and the door.

[0021] (6) Using screws to install the elastic seal on the moving part provides good connection strength and facilitates the disassembly and maintenance of the elastic seal. Furthermore, the use of gaskets allows the rigid gaskets to withstand the pressure exerted by the screws on the connection during tightening, preventing deformation or damage due to excessive pressure. Simultaneously, because the elastic seal has relatively low hardness, inserting the screws into the gaskets ensures a more secure installation of the elastic seal compared to a direct connection between the elastic seal and the moving part.

[0022] (7) Through the cooperation of the slot and the retaining ring, the connecting part can be snapped into the gasket, ensuring that the gasket can be kept in the mounting hole, so as to prevent the connecting part from coming off the gasket and causing the connection between the connecting part and the moving part to fail.

[0023] (8) By setting the abutting protrusion, when the elastic seal is installed on the moving part, the abutting protrusion can abut against the moving part and undergo elastic deformation, making the sealing part and the moving part fit more tightly. The abutting protrusion itself can also serve as a sealing structure to seal the gap between the sealing part and the moving part. At the same time, if a gap is generated between the sealing part and the moving part due to wear caused by external forces such as vibration, the abutting protrusion can seal the gap between the sealing part and the moving part due to its own protrusion towards the moving part and elastic deformation, thereby further improving the sealing performance between the elastic seal and the moving part.

[0024] This application also proposes a vehicle having a hinge structure as described above.

[0025] Furthermore, the vehicle body is provided with a decorative cover, which covers the outside of the fixing member, and the decorative cover is provided with a clearance groove to avoid the hinge arm; the decorative cover is provided with a sealing strip, and part of the sealing strip abuts against the door, and part of the sealing strip is located in the clearance groove and abuts against the hinge arm.

[0026] The vehicle described in this application, through the aforementioned hinge structure, can seal the gap between the door and the hinge arm, preventing water from entering the door and thus ensuring the user experience of the vehicle.

[0027] Furthermore, by installing a decorative cover on the vehicle body, the fasteners can be folded, ensuring not only the vehicle's aesthetics but also protecting the fasteners from damage due to exposure. Simultaneously, the clearance groove prevents the decorative cover from interfering with the hinge arm when the door opens and closes, ensuring smooth door operation. Moreover, the sealing strip seals the gap between the decorative cover and the hinge arm, improving the seal and preventing external impurities from entering beneath the decorative cover and affecting the normal operation of the hinge structure.

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.

[0055] 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.

[0056] An embodiment of the first aspect of this application provides a hinge structure suitable for connecting a door 4 to a vehicle body.

[0057] In some vehicle models, the hinge structure used to connect the door 4 to the vehicle body is typically exposed directly on the outside of the vehicle. A certain gap is usually provided between the door 4 and the hinge structure to meet the manufacturing tolerances of the door 4 sheet metal and the hinge structure, as well as their assembly tolerances. However, due to this gap, water from outside the vehicle can easily enter the inside of the door 4, causing water ingress and affecting the overall user experience.

[0058] In view of this, in order to overcome the shortcomings of related technologies, the hinge structure of this embodiment combines... Figure 1 , Figure 2As shown, the overall design includes a movable part 1 on the door 4 and an elastic sealing part 2 on the movable part 1.

[0059] The movable component 1 has an outwardly extending hinge arm 101, which is hingedly connected to a fixed component 3 on the vehicle body, and a gap is formed between the hinge arm and the door 4. The elastic seal 2 has a connecting portion 201 and a sealing portion 202, with the connecting portion 201 connected to the movable component 1 and the sealing portion 202 filling the gap.

[0060] Therefore, through the setting of the elastic seal 2, the sealing part 202 of the elastic seal 2 can fill the gap between the hinge arm 101 and the door 4. This not only ensures the delicate appearance of the hinge arm 101 of the door 4, but also seals the gap between the hinge arm 101 and the door 4. This effectively prevents external water from entering the inside of the door 4 through the gap between the hinge arm 101 and the door 4, thereby effectively preventing water from entering the door 4 and improving the overall user experience of the vehicle.

[0061] Based on the above overview, specifically, let's continue to combine... Figure 1 As shown, a hinge arm 101 is formed at one end of the movable member 1, and the other end of the movable member 1 has a connecting structure 102 for connecting the door 4. The sheet metal of the door 4 extends inward to form a connecting portion 201 for connecting with the movable member 1. The connecting structure 102 extends laterally, and its opposite ends are provided with through holes for inserting connecting members such as bolts and rivets. The connecting portion 201 of the sheet metal of the door 4 is provided with mounting holes 2011 corresponding to the through holes. The connecting members pass through the through holes and are connected in the mounting holes 2011, thereby achieving the connection and fixation between the movable member 1 and the door 4.

[0062] Furthermore, the fastener 3 includes a mounting base 301 for connecting to the vehicle body and a hinge end 302 that is hinged to the hinge arm. The mounting base 301 has through holes for inserting connectors, located on both sides of the hinge end 302, allowing the mounting base 301 to be mounted on the vehicle body using connectors such as bolts or rivets. Simultaneously, a buffer pad 304 is provided on the side of the mounting base 301 facing the vehicle body. The buffer pad 304 is located at the through holes and can be clamped between the mounting base 301 and the vehicle body to reduce the transmission of vibrations generated by the vehicle body to the vehicle body, thus reducing abnormal noise. It also provides some protection to the connection between the hinge arm and the vehicle body, preventing loosening or fatigue damage due to long-term vibration.

[0063] Combination Figure 7 , Figure 8 and Figure 9As shown, in some exemplary embodiments, one side of the sealing portion 202 abuts against the hinge arm 101, and the other side of the sealing portion 202 interferes with the door 4.

[0064] By interfering with the door 4, the elastic deformation of the sealing part 202 allows it to fit tightly against the door 4, sealing the gap between them. Simultaneously, the sealing part 202 abuts against the hinge arm, ensuring not only a seal between them but also support from the hinge arm 101. This allows the sealing part 202 to apply sufficient pressure to the door 4, further facilitating a tight fit between them and ensuring the seal between the door 4 and the hinge arm 101.

[0065] In some exemplary embodiments, the gap width d1 is between 4.0mm and 5.0mm. It is understandable that if the gap width is too small, the hinge arm 101 may interfere with the door 4 during assembly due to manufacturing and assembly tolerances, or hinder the smooth progress of the assembly operation. Conversely, if the gap width is too large, the gap between the door 4 and the hinge arm 101 will be more noticeable, affecting the vehicle's aesthetics and increasing the volume of the required sealing portion 202, thus increasing the production cost of the elastic seal 2 to some extent.

[0066] Furthermore, the interference amount d2 between the sealing part 202 and the door 4 is not less than 0.8mm. It is understandable that if the interference amount between the sealing part 202 and the door 4 is too small, it can easily lead to a loose fit between them, causing gaps and affecting the sealing performance. If the interference amount between the sealing part 202 and the door 4 is too large, it can cause the door 4 to excessively compress the sealing part 202, resulting in excessive pressure on the door 4 sheet metal and potential damage.

[0067] Therefore, by limiting the width of the gap, sufficient clearance can be maintained between the door 4 and the hinge arm 101 to avoid interference between the hinge arm 101 and the sheet metal of the door 4 due to manufacturing and assembly tolerances, and to provide sufficient installation space for the elastic seal 2. Furthermore, by limiting the amount of interference between the sealing part 202 and the door 4, not only can a tight fit between the sealing part 202 and the door 4 be ensured, guaranteeing a good seal, but excessive interference can also prevent the sealing part 202 from being excessively compressed and protruding outwards, affecting the flatness of the hinge structure of the door 4, or causing excessive pressure on the door 4 due to excessive interference, leading to deformation of the door 4 structure or damage to the paint surface of the door 4.

[0068] Combination Figure 8 and Figure 9 As shown, in some exemplary embodiments, the sealing portion 202 has a protrusion 2021 protruding toward the door 4 and a recess 2022 located at the root of the protrusion 2021. The protrusion 2021 interferes with the door 4, and the recess 2022 is used to avoid the door 4.

[0069] Specifically, in this embodiment, the recess 2022 is located at the root of the protrusion 2021. From the perspective of the gap's extension direction, the recess 2022's arrangement results in the width of the sealing portion 202 below the protrusion 2021 being smaller than the width of the sealing portion 202 where the protrusion 2021 is located. This allows the sealing portion 202 below the protrusion 2021 to provide clearance to the vehicle door 4.

[0070] Therefore, through the coordinated arrangement of the protrusion 2021 and the recess 2022, the recess 2022 provides sufficient elastic deformation space for the protrusion 2021. This allows the protrusion 2021 to deform sufficiently under pressure when it interferes with the door 4, ensuring a tight fit between the protrusion 2021 and the door 4. It also increases the contact area between the protrusion 2021 and the door 4 to a certain extent, thus improving sealing performance. Simultaneously, the recess 2022 prevents other areas of the sealing portion 202 from contacting the door 4, preventing excessive interference between the sealing portion 202 and the door 4, which could affect the assembly of the elastic seal 2, i.e., the hinge structure, with the door 4.

[0071] In some exemplary embodiments, the connecting portion 201 is located between the movable member 1 and the door 4, and the sealing portion 202 is connected to one end of the connecting portion 201. The hinge arm 101 has a protrusion that extends outward toward the door 4, and the sealing portion 202 abuts against the protrusion.

[0072] Understandably, due to the interference between the door 4 and the sealing part 202, the door 4 will cause the sealing part 202 to shift away from the door 4. This will result in the sealing part 202 not being able to tightly abut against the door 4, and applying enough pressure to the door 4, making it difficult to ensure the tightness of the seal between the sealing part 202 and the door 4.

[0073] Therefore, by placing the connecting portion 201 between the movable part 1 and the door 4, and connecting it to one side of the sealing portion 202, it is possible to prevent the connecting portion 201 from affecting the arrangement of the sealing portion 202 at the gap, and to facilitate the assembly and connection of the elastic seal 2 and the movable part 1. Furthermore, the protruding portion increases the contact area between the hinge arm 101 and the elastic seal 2. At the same time, the protruding portion can abut against the sealing portion 202, forming a support for the sealing portion 202, ensuring the pressure applied by the sealing component to the door 4, and thus ensuring the sealing effect between the sealing portion 202 and the door 4.

[0074] Combination Figure 8 As shown, in some exemplary embodiments, the connecting portion 201 is provided with a mounting hole 2011 and a rigid washer 5 disposed in the mounting hole 2011. The connecting portion 201 is connected to the movable member 1 by a screw 6 passing through the washer 5.

[0075] The elastic seal 2 is installed on the movable part 1 using the screw connector 6, which provides good connection strength and facilitates the disassembly and maintenance of the elastic seal 2. Furthermore, the rigid gasket 5 can withstand the pressure of the screw connector 6 on the connecting part 201 during the tightening of the screw connector 6, thus preventing the connecting part 201 from deforming or being damaged due to excessive pressure.

[0076] Meanwhile, because the elastic seal 2 has relatively low hardness, inserting the screw 6 into the gasket 5 ensures the secure installation of the elastic seal 2 compared to a direct connection between the elastic seal 2 and the moving part 1. Furthermore, the gasket 5 also helps to prevent the screw 6 from loosening from the moving part 1 to some extent.

[0077] Furthermore, in combination Figures 9 to 12 As shown, in some exemplary embodiments, the outer peripheral wall of the gasket 5 is provided with a groove 501, and the wall of the mounting hole 2011 is provided with a retaining ring 2012. The gasket 5 is engaged in the mounting hole 2011 by the groove 501 and the retaining ring 2012.

[0078] With the cooperation of the slot 501 and the retaining ring 2012, the connecting part 201 can be snapped into the gasket 5, ensuring that the gasket 5 can be kept in the mounting hole 2011, so as to prevent the connecting part 201 from coming off the gasket 5 and causing the connection between the connecting part 201 and the moving part 1 to fail.

[0079] In specific implementation, the slot 501 of this embodiment is composed of two annular structures on the outer peripheral wall of the gasket 5. The radial extension length of the annular structure near the movable member 1 is less than the radial length of the other annular structure near the screw connector 6. Simultaneously, a guide surface is provided on the annular structure near the movable member 1. This arrangement facilitates the insertion of the gasket 5 into the mounting hole 2011 of the connecting portion 201, allowing the retaining ring 2012 to engage in the slot 501, thus facilitating the connection between the gasket 5 and the elastic seal 2. Furthermore, the side of the retaining ring 2012 near the screw connector 6 and in contact with the gasket 5 has a larger contact area, enabling the gasket 5 to stably press the connecting portion 201 against the movable member 1, thereby improving the fixing effect of the connecting portion 201.

[0080] Combination Figure 6 , Figure 9 and Figure 11As shown, in some exemplary embodiments, the sealing portion 202 is provided with an abutment protrusion 2023 that abuts against the movable member 1.

[0081] It is understandable that if the sealing part 202 does not have the abutting protrusion 2023, when the elastic seal 2 is installed on the movable part 1, there is a large abutting surface between the movable part 1 and the sealing part 202. During the opening and closing of the car door 4, external forces such as vibration can easily cause wear between the sealing part 202 and the movable part 1, resulting in a gap.

[0082] Furthermore, the screw connector 6 can only press the connecting part 201 tightly onto the movable part 1 to fix the elastic seal 2, so that the sealing part 202 cannot be driven by external force to stick to the movable part 1. This will cause the gap between the sealing part 202 and the movable part 1 to be unable to be sealed due to the deformation of the sealing part 202, thereby affecting the sealing performance.

[0083] When the sealing part 202 is provided with the abutting protrusion 2023, the abutting protrusion 2023 can cause the sealing part 202 to have a tendency to flip towards the door 4. The door 4 and the sealing part 202 have a certain degree of interference, which allows the door 4 to drive the sealing part 202 to return to its original position, thereby causing the sealing part 202 to flip towards the movable part 1, so that the sealing part 202 is driven by the external force from the door 4. During this process, the sealing part 202 can be pressed tightly against the movable part 1 by the action of the door 4, so that the abutting protrusion 2023 abuts against the movable part 1 and undergoes elastic deformation due to compression, thereby enabling the abutting protrusion 2023 to seal the gap between the sealing part 202 and the movable part 1.

[0084] Therefore, by setting the abutment protrusion 2023, when the elastic seal 2 is installed on the movable part 1, the abutment protrusion 2023 can abut against the movable part 1 and undergo elastic deformation, making the sealing part 202 and the movable part 1 fit more tightly. Furthermore, the abutment protrusion 2023 itself can serve as a sealing structure to seal the gap between the sealing part 202 and the movable part 1. Simultaneously, if a gap is created between the sealing part 202 and the movable part 1 due to wear caused by external forces such as vibration, the abutment protrusion 2023 can seal the gap between the sealing part 202 and the movable part 1 due to its own protrusion towards the movable part 1 and its elastic deformation, thereby further improving the sealing performance between the elastic seal 2 and the movable part 1.

[0085] In specific implementation, the abutment protrusion 2023 of this embodiment can be set to multiple, so that the sealing part 202 and the movable part 1 form a multi-seal structure, so as to further improve the sealing performance between the elastic seal 2 and the movable part 1.

[0086] 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 5 As shown in the image.

[0087] The hinge structure of this embodiment includes a movable part 1 and an elastic seal 2 disposed on the movable part 1.

[0088] The movable component 1 is located on the door 4 and has an extended hinge arm 101. The hinge arm 101 is hingedly connected to the fixed component 3 located on the vehicle body. The end of the movable component 1 away from the hinge arm 101 is provided with a connecting structure 102 for connecting to the door 4.

[0089] Specifically, the sheet metal of the door 4 extends inward to form a connecting portion 201 for connecting with the movable part 1. The connecting structure 102 extends laterally, and its opposite ends are provided with through holes for inserting connecting parts such as bolts and rivets. The connecting portion 201 of the sheet metal of the door 4 is provided with mounting holes 2011 corresponding to the through holes. The connecting parts pass through the through holes and are connected in the mounting holes 2011, thereby realizing the connection and fixation between the movable part 1 and the door 4.

[0090] Furthermore, the fastener 3 includes a mounting base 301 for connecting to the vehicle body and a hinge end 302 that is hinged to the articulated arm. The mounting base 301 is provided with through holes for the connecting member to pass through. These through holes are located on both sides of the hinge end 302, and the mounting base 301 can be installed on the vehicle body by connecting members such as bolts or rivets to ensure the connection strength between the fastener 3 and the vehicle body.

[0091] Meanwhile, a buffer pad 304 is provided on the side of the mounting base 301 facing the vehicle body. The buffer pad 304 is located at the through hole and can be clamped between the mounting base 301 and the vehicle body to reduce the transmission of vibrations generated by the vehicle body to the vehicle body to a certain extent, thereby reducing the generation of abnormal noises. At the same time, it can also protect the connection between the hinge seat and the vehicle body to a certain extent, preventing loosening or fatigue damage due to long-term vibration.

[0092] Furthermore, the resilient seal 2 has a connecting portion 201 and a sealing portion 202. The connecting portion 201 is connected to the movable member 1 and is located between the movable member 1 and the door 4. The sealing portion 202 is connected to one end of the connecting portion 201. The hinge arm 101 has a protruding portion that protrudes outward toward the door 4. The sealing portion 202 abuts against the protruding portion, such that the protruding portion provides support for the sealing portion 202, ensuring the pressure applied by the sealing member to the door 4, thereby ensuring the sealing effect between the sealing portion 202 and the door 4.

[0093] Furthermore, the connecting portion 201 is provided with a mounting hole 2011 and a rigid gasket 5 disposed in the mounting hole 2011. The gasket 5 is used to bear the pressure of the screw 6 on the connecting portion 201, so as to prevent the connecting portion 201 from deforming or being damaged due to excessive pressure. Compared with the direct connection between the elastic seal 2 and the movable part 1, it can also ensure the firmness of the elastic seal 2. The connecting portion 201 is connected to the movable part 1 by the screw 6 passing through the gasket 5. The outer peripheral wall of the gasket 5 is provided with a groove 501, and the wall of the mounting hole 2011 is provided with a retaining ring 2012. The gasket 5 is engaged in the mounting hole 2011 through the groove 501 and the retaining ring 2012. This ensures that the gasket 5 can be kept in the mounting hole 2011, so as to prevent the connecting portion 201 from coming off the gasket 5 and causing the connection between the connecting portion 201 and the movable part 1 to fail.

[0094] Meanwhile, a gap is formed between the hinge arm and the door 4, and the sealing part 202 fills the gap. The width d1 of the gap is between 4.0mm and 5.0mm, which can ensure that there is enough gap between the door 4 and the hinge arm 101 to avoid interference between the hinge arm 101 and the sheet metal of the door 4 due to the manufacturing tolerance and assembly tolerance of the door 4 and the hinge arm 101, and to provide sufficient installation space for the elastic seal 2.

[0095] Furthermore, one side of the sealing portion 202 abuts against the hinge arm 101, while the other side of the sealing portion 202 interferes with the door 4. The sealing portion 202 has a protrusion 2021 protruding towards the door 4 and a recess 2022 located at the root of the protrusion 2021. The protrusion 2021 interferes with the door 4, while the recess 2022 avoids the door 4, thus providing sufficient elastic deformation space for the protrusion 2021. This allows the protrusion 2021 to deform sufficiently under pressure when interfering with the door 4, ensuring a tight fit between the protrusion 2021 and the door 4, and increasing the contact area between the protrusion 2021 and the door 4 to a certain extent, thereby improving sealing performance. Simultaneously, the recess 2022 prevents other areas of the sealing portion 202 from contacting the door 4, preventing excessive interference between the sealing portion 202 and the door 4, which could affect the assembly of the moving part 1 and the door 4.

[0096] Specifically, the interference amount d2 between the protrusion 2021 and the sealing part 202 is not less than 0.8mm. This not only ensures a tight fit between the sealing part 202 and the door 4, guaranteeing a sealing effect, but also prevents the sealing part 202 from being excessively compressed and protruding outward due to excessive interference, which would affect the flatness of the hinge structure of the door 4, or prevents excessive pressure on the door 4 due to excessive interference, which could lead to deformation of the door 4 structure or damage to the paint surface of the door 4.

[0097] In addition, the sealing part 202 is provided with an abutting protrusion 2023, which abuts against the movable part 1. Two abutting protrusions 2023 are provided, so that the sealing part 202 and the movable part 1 form a double sealing structure to further improve the sealing performance between the elastic seal 2 and the movable part 1.

[0098] The hinge structure of this embodiment adopts the above design. With the setting of the elastic seal 2, the sealing part 202 of the elastic seal 2 can fill the gap between the hinge arm 101 and the door 4. This not only ensures the delicate position of the hinge arm 101 of the door 4, but also seals the gap between the hinge arm 101 and the door 4. This effectively prevents external water from entering the inside of the door 4 through the gap between the hinge arm 101 and the door 4, thereby effectively avoiding water entering the door 4 and improving the overall user experience of the vehicle. It has good practicality.

[0099] An embodiment of the second aspect of this application provides a vehicle, which, in its overall structure, has a hinge structure as described above.

[0100] In this embodiment, the vehicle, through the aforementioned hinge structure, can seal the gap between the door 4 and the hinge arm 101, preventing water from entering the door 4 and thus ensuring the user experience of the vehicle.

[0101] Based on the above overall introduction, specifically, combined with Figures 3 to 5 As shown, in some exemplary embodiments, a decorative cover 7 is provided in the vehicle body, which covers the outside of the fastener 3, and the decorative cover 7 is provided with a clearance groove 701 for the hinge arm 101. A sealing strip 8 is provided on the decorative cover 7, and part of the sealing strip 8 abuts against the door 4, while part of the sealing strip 8 is located in the clearance groove 701 and abuts against the hinge arm 101.

[0102] By installing a decorative cover 7 on the vehicle body, the fasteners 3 can be concealed, ensuring not only the aesthetics of the vehicle body but also protecting the fasteners 3 from damage due to exposure. Simultaneously, the clearance groove 701 prevents the decorative cover 7 from interfering with the hinge arm 101 when the door 4 opens and closes, ensuring smooth operation of the door 4. Furthermore, the sealing strip 8 seals the gap between the decorative cover 7 and the hinge arm 101, improving the seal between them and preventing external impurities from entering below the decorative cover 7 and affecting the normal operation of the hinge structure.

[0103] In specific implementation, combined with Figure 5 and Figure 7As shown, the decorative cover 7 has a connecting lug 702 on the side facing the fixing member 3, and the fixing base 301 of the fixing member 3 has a connecting end 303 for connecting the lug 702. The connecting end 303 is configured as two separate ends on both sides of the hinge end 302. The connecting end 303 and the connecting lug 702 can be connected together through a connector, thereby realizing the connection and fixation between the decorative cover 7 and the fixing member 3, ensuring the fixing effect of the decorative cover 7, preventing the cover from detaching, and ensuring that the decorative cover 7 can cover the fixing member 3.

[0104] Furthermore, in this embodiment, the end of the sealing strip 8 bends inward toward the vehicle body. During the closing process of the door 4, the arc-shaped sealing lip can utilize its own elastic deformation to buffer the door 4 and the moving end of the hinge. At the same time, the sealing lip bending inward is in the same direction of movement as the door 4 when it closes, which can reduce the friction between the sealing lip and the door 4 and ensure a tight fit between the sealing lip and the door 4 when the door 4 is closed, further improving the sealing performance.

[0105] The above descriptions are merely some embodiments of this application and are not intended to limit this application. The technical features or structures in the foregoing different embodiments can be arbitrarily combined to form other specific technical solutions as needed. For those skilled in the art, this application can have various modifications and variations. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the scope of protection of the claims of this application.
