Description

Technical Field

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

[0002] In the installation structure of a car door, the stability of the connection between the door and the body directly affects the vehicle's safety, sealing performance, and user experience. Car doors are typically connected to the body via hinges to enable their rotating opening and closing function.

[0003] However, when a vehicle is traveling at high speed, the high-speed airflow outside the vehicle body can easily create negative pressure. The doors are easily affected by the pressure difference between the inside and outside of the vehicle, resulting in a force acting outwards on the vehicle. This can cause gaps between the door and the body, producing abnormal noises, affecting the vehicle's sealing performance, and even leading to safety accidents caused by the doors opening unexpectedly. As a result, the reliability of the doors when closed is relatively poor. Utility Model Content

[0004] In view of this, this application aims to provide a door mounting structure to improve the reliability of the door in the closed state.

[0005] To achieve the above objectives, the technical solution of this application is implemented as follows: A door mounting structure includes a first hinge disposed between a vehicle roof and a door, a second hinge disposed between a vehicle side panel and the door, and a limiting structure disposed between the vehicle side panel and the door. The limiting structure includes a first limiting member disposed on the side wall of the vehicle body and a second limiting member disposed at the front end of the door. When the door is closed, the first limiting member blocks the side of the second limiting member that is closer to the outside of the vehicle, so as to limit the displacement of the door to the outside of the vehicle.

[0006] Furthermore, the second limiting member includes a mounting block disposed on the door and a limiting arm extending toward the side of the vehicle body; the limiting arm bends toward the side closer to the first limiting member.

[0007] Furthermore, the first limiting member has an abutment ramp at one end near the limiting arm, and when the door is closed, the abutment ramp blocks at least part of the limiting arm on the side near the outside of the vehicle.

[0008] Furthermore, the mounting block is disposed on the inner panel of the door and located at the bottom of the front end of the inner panel; the side panel of the vehicle body is provided with a protrusion protruding outward to one side of the vehicle, the first limiting member is disposed on the protrusion, and along the direction of the whole vehicle from front to back, the first limiting member is inclined upward.

[0009] Furthermore, a limiting block is provided at the rear end of the door, and an abutment protrusion protruding outward on the side of the vehicle body is provided; when the door is closed, the abutment protrusion is positioned below the limiting block and is used to restrict the downward displacement of the limiting block.

[0010] Furthermore, the outer wall of the limiting block is provided with a slot, and the limiting block is engaged with the inner panel of the car door through the slot; and / or, the limiting block, the first limiting member and the second limiting member are all made of elastic material.

[0011] Furthermore, the vehicle body side panel includes a side panel outer plate, the side panel outer plate having a sill outer plate extending along the front-rear direction of the whole vehicle, and a front pillar outer plate and a rear pillar outer plate respectively disposed at the front and rear ends of the sill outer plate; the second hinge is disposed between the front pillar outer plate and the door, the rear pillar outer plate having a protruding portion extending along the vertical direction of the whole vehicle, and the bottom end of the protruding portion is bent forward to form the abutting protrusion.

[0012] Furthermore, the second hinge includes a fixed member disposed on the side panel of the vehicle body and a movable member disposed on the door, the fixed member being rotatably connected to the movable member; an assisting element is provided between the movable member and the bottom end of the side panel of the vehicle body, and the two ends of the assisting element are respectively connected to the movable member and the ball joint of the side panel of the vehicle body.

[0013] Furthermore, the movable component includes a main body connected to the vehicle door, and a hinge arm provided on the main body. The hinge arm extends towards the front of the main body and is hingedly connected to the fixing component. The hinge arm is provided with a mounting protrusion protruding to the outside of the vehicle and a ball head provided on the mounting protrusion. The assisting element is provided with a ball socket that mates with the ball head.

[0014] Compared with related technologies, this application has the following advantages: (1) The door mounting structure described in this application enables the opening and closing of the door through the setting of the first hinge and the second hinge. At the same time, through the cooperation of the first limiting member on the vehicle body and the second limiting member on the door, the first limiting member can block the second limiting member from moving to the outside of the vehicle when the door is closed, thereby limiting the door from opening to the outside of the vehicle, thus effectively improving the reliability of the door when it is closed.

[0015] (2) By setting the mounting block, it can serve as the connection base between the second limiting member and the door, so that the second limiting member can be installed on the door. Furthermore, by setting the limiting arm, the limiting arm bends toward one side of the first limiting member, so that the first limiting member can block one side of the second limiting member, and the area of ​​the limiting arm used to block the first limiting member can be effectively increased, thereby improving the reliability of the first limiting member in limiting the second limiting member.

[0016] (3) By setting the avoidance ramp, when the door is closed, the avoidance ramp can block the limiting arm to restrict the door from opening outward. At the same time, during the opening of the door, the avoidance ramp can abut against the limiting arm and guide the limiting arm to move away from the first limiting member, so that the limiting arm can be freed from the obstruction of the first limiting member, so as to ensure that the door can be opened smoothly and reduce the wear of the limiting arm.

[0017] (4) By placing the mounting block at the bottom of the front end of the inner panel of the door, it can be positioned at the cantilever end of the door, effectively restricting the door from opening outwards. Furthermore, it fully utilizes the open mounting space at the front of the door, avoiding interference with components such as the door lock. The protrusion on the side panel of the vehicle body provides a stable mounting base for the first limiting member and structurally reinforces the side panel. The upward tilt of the first limiting member matches the closing trajectory of the door, effectively preventing interference with the opening and closing of the door.

[0018] (5) By setting the limiting block and the abutting protrusion, when the door is closed, the abutting protrusion can block the bottom of the limiting block and abut against the limiting block to prevent the door from moving downward due to vibration, which helps to improve the stability of the door in the closed state.

[0019] (6) By setting a slot on the limiting block, the limiting block can be snapped onto the inner panel of the door to facilitate the assembly of the limiting block. The limiting block, the first limiting member and the second limiting member are all made of elastic material, which can play a buffering role between the first and second limiting members and between the limiting block and the side panel of the vehicle body during the opening and closing of the door, avoid rigid contact between the components, extend the service life of the limiting structure, and effectively reduce the noise generated when the door is closed.

[0020] (7) By placing the second hinge on the outer panel of the front pillar, the better structural strength of the outer panel of the front pillar is utilized to improve the connection strength of the second hinge on the vehicle body and ensure the load-bearing effect on the door. At the same time, the structural strength of the outer panel of the rear pillar is improved by setting the protruding part. The abutment protrusion is placed on the protruding part, which can improve the limiting effect of the limiting block and also eliminate the need to set the additional abutment protrusion, making it easier to process and manufacture. Moreover, when the limiting block abuts against the abutment protrusion, the abutment protrusion can disperse the impact force from the limiting block to other parts of the vehicle body through the outer panel of the rear pillar and the outer panel of the door sill.

[0021] (8) The door can be opened and closed by the cooperation of the fixed and movable parts. At the same time, an assistive element is provided between the movable part and the side of the vehicle body to provide assistance when opening and closing the door, so as to reduce the operating force when opening and closing the door and improve the convenience of using the door. In addition, the assistive element adopts a ball joint connection method, which can flexibly adjust the angle during the opening and closing of the door to prevent the assistive element from interfering with other parts and ensure the stability of the assistive effect.

[0022] (9) By setting the main body and the hinge arm and extending the hinge arm forward, the range of motion of the second hinge can be expanded so that the door can open and close along the preset trajectory. Through the cooperation of the ball head and the ball socket, the power assist element can move at multiple angles, avoiding interference and jamming when the door is opened and closed, and further improving the smoothness of the door opening and closing and the stability of the power assist effect.

[0023] Another object of this application is to provide a vehicle having a door mounting structure as described above.

[0024] The vehicle and / or door mounting structure described in this application have the same technical effect as related technologies, and will not be described in detail here. Attached Figure Description

In addition, if terms such as "upper" or "lower" appear, they are also used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0029] Furthermore, in the description of this application, unless otherwise expressly defined, the terms "installation," "connection," "joining," and "connector" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this application in light of the specific circumstances.

[0030] In this application, the terms "one embodiment," "some embodiments," "example," "specific example," or "some examples," etc., refer to a specific feature, structure, material, or characteristic described in connection with that embodiment or example, which is included in at least one embodiment or example of this application. 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 door mounting structure.

[0033] In related technologies, when a vehicle is traveling at high speed, the high-speed airflow outside the vehicle body can easily generate negative pressure. This is especially true for butterfly doors, where the doors are easily affected by the pressure difference between the inside and outside of the vehicle, resulting in a force acting outwards. This can cause gaps between the door and the body, producing abnormal noises, affecting the vehicle's sealing performance, and even leading to safety accidents caused by the door opening unexpectedly. Consequently, the reliability of the doors is relatively poor when closed.

[0034] In view of this, in order to overcome the shortcomings of the related technology, the door mounting structure of this embodiment combines... Figure 1 , Figure 2 and Figure 11 As shown, the overall design includes a first hinge 1 located between the roof and the door, a second hinge 3 located between the side panel and the door, and a limiting structure located between the side panel and the door.

[0035] The limiting structure includes a first limiting member 4 provided on the side wall of the vehicle body and a second limiting member 5 provided at the front end of the door. When the door is closed, the first limiting member 4 blocks the second limiting member 5 on the side closer to the outside of the vehicle to limit the displacement of the door to the outside of the vehicle.

[0036] Therefore, by setting the first hinge 1 and the second hinge 3, the opening and closing of the car door can be realized. At the same time, by cooperating with the first limiting member 4 on the car body and the second limiting member 5 on the car door, when the car door is closed, the first limiting member 4 can prevent the second limiting member 5 from moving to the outside of the vehicle, thereby restricting the car door from opening to the outside of the vehicle, thus effectively improving the reliability of the car door in the closed state.

[0037] Based on the above overall introduction, specifically, combined with Figure 11 , Figure 12 As shown, in some exemplary embodiments, the second limiting member 5 includes a mounting block 501 disposed on the door and a limiting arm 502 extending toward the side of the vehicle body. The limiting arm 502 bends toward the side closer to the first limiting member 4.

[0038] By setting the mounting block 501, it can serve as the connection base between the second limiting member 5 and the car door, so that the second limiting member 5 can be installed on the car door. Furthermore, by setting the limiting arm 502, the limiting arm 502 bends towards one side of the first limiting member 4, so that the first limiting member 4 can block one side of the second limiting member 5, and the area of ​​the limiting arm 502 used to block the first limiting member 4 can be effectively increased, thereby improving the reliability of the first limiting member 4 in limiting the second limiting member 5.

[0039] In specific implementation, the mounting block 501 of this embodiment is roughly arc-shaped and has two spaced mounting holes. By inserting bolts through the mounting holes, the mounting block 501 can be screwed onto the inner panel 6 of the car door.

[0040] It should be noted that the number of mounting holes is not limited to the two shown in the figure, and can be adjusted according to design requirements. In addition, besides using bolts to screw the mounting block 501 onto the inner panel 6 of the door, it can also be installed onto the inner panel 6 of the door using snap-fit ​​or other conventional methods.

[0041] Combination Figure 11 , Figure 13 As shown, in some exemplary embodiments, the first limiting member 4 has a clearance ramp 401 at one end near the limiting arm 502. When the door is closed, the clearance ramp 401 blocks at least part of the limiting arm 502 on the side near the outside of the vehicle.

[0042] By setting the avoidance ramp 401, when the door is closed, the avoidance ramp 401 can block the limiting arm 502 to restrict the door from opening outward. At the same time, during the opening of the door, the avoidance ramp 401 can abut against the limiting arm 502 and guide the limiting arm 502 to move away from the first limiting member 4, so that the limiting arm 502 is freed from the obstruction of the first limiting member 4, thereby ensuring that the door can open smoothly and reducing the wear of the limiting arm 502.

[0043] In specific implementation, such as Figure 11 As shown, the first limiting member 4 is block-shaped and located in front of the second limiting member 5, that is, the avoidance ramp 401 is located at the rear end of the first limiting member 4. The avoidance ramp 401 not only prevents the limiting arm 502 from moving to the outside of the vehicle, but also creates an avoidance space between the first limiting member 4 and the side of the vehicle body to avoid the limiting arm 502. Compared with the structure of forming a limiting protrusion on the first limiting member 4 to block the limiting arm 502, the space occupied in the width direction of the vehicle can be reduced, and the design and implementation can be facilitated.

[0044] Combination Figure 8 As shown, in some exemplary embodiments, the mounting block 501 is provided on the inner panel 6 of the door and located at the bottom of the front end of the inner panel 6. A protrusion 2021 protruding outward is provided on the side of the vehicle body, and a first limiting member 4 is provided on the protrusion 2021, and the first limiting member 4 is inclined upward along the direction from front to back of the whole vehicle.

[0045] By placing the mounting block 501 at the bottom of the front end of the inner panel 6 of the door, it is positioned at the cantilever end of the door, effectively restricting the door from opening outwards. Furthermore, it fully utilizes the open mounting space at the front of the door, avoiding interference with components such as the door lock. The protrusion 2021 on the side panel of the vehicle body provides a stable mounting base for the first limiting member 4 and structurally reinforces the side panel. The upward tilt of the first limiting member 4 matches the closing trajectory of the door, effectively preventing interference with the opening and closing of the door.

[0046] In practical implementation, the inner panel 6 of this embodiment has a main body portion protruding towards the outer panel side away from the door, and an edge portion provided along the edge of the main body portion. The mounting block 501 is specifically located at the pointed corner at the bottom front end of the main body portion. In addition, due to limitations in the manufacturing process, a reinforcing plate 601 is spliced ​​at the bottom front end of the main body portion, and the mounting block 501 is specifically located on the reinforcing plate 601 to ensure the connection strength between the mounting block 501 and the door and improve the stability of the second limiting member 5.

[0047] Furthermore, to ensure the first limiting member 4 is tilted upwards, a positioning protrusion 402 is provided on the side of the first limiting member 4 facing the protrusion 2021, and two positioning protrusions 402 are configured. Simultaneously, positioning holes corresponding to the positioning protrusions 402 are provided on the protrusion 2021. When the first limiting member 4 is installed on the protrusion 2021 of the vehicle body side panel, the two positioning protrusions 402 can be inserted into their corresponding positioning holes, thus limiting the installation angle of the first limiting member 4 and maintaining its upward tilted state.

[0048] In addition, in this embodiment, the first limiting member 4 is installed on the protrusion 2021 by bolts. When the positioning protrusion 402 is inserted into the positioning hole, it can play a role in pre-positioning the first limiting member 4, thereby facilitating the assembly operation of the first limiting member 4.

[0049] Combination Figure 3 , Figure 4 and Figure 10 As shown, in some exemplary embodiments, a limiting block 7 is provided at the rear end of the door, and an abutment protrusion 2032 protruding outward on the side of the vehicle body is provided. When the door is closed, the abutment protrusion 2032 blocks the lower part of the limiting block 7 and is used to limit the downward displacement of the limiting block 7.

[0050] With the setting of the limiting block 7 and the abutting protrusion 2032, when the door is closed, the abutting protrusion 2032 can be placed below the limiting block 7 and abut against the limiting block 7 to prevent the door from moving downward due to vibration, which helps to improve the stability of the door when it is closed.

[0051] Furthermore, in some exemplary embodiments, the outer wall of the limiting block 7 is provided with a slot 701, and the limiting block 7 is snapped onto the inner panel 6 of the door through the slot 701. By providing the slot 701 on the limiting block 7, the limiting block 7 can be snapped onto the inner panel 6 of the door, so as to facilitate the assembly of the limiting block 7.

[0052] Meanwhile, in some exemplary embodiments, the limiting block 7, the first limiting member 4, and the second limiting member 5 are all made of elastic material, which can buffer the first and second limiting members 5 and the limiting block 7 and the side wall of the vehicle body during the opening and closing of the door, avoid rigid contact between the components, extend the service life of the limiting structure, and effectively reduce the noise generated when the door is closed.

[0053] Preferably, in this embodiment, the limiting block 7, the first limiting member 4 and the second limiting member 5 are all made of rubber, and the outer wall of the limiting block 7 is provided with a groove 701, so that while utilizing the elastic properties of rubber to play a buffering role, the limiting block 7 has good elasticity, so as to facilitate its assembly into the snap-fit ​​hole of the inner panel 6 of the car door, thereby further facilitating the assembly operation of the limiting block 7.

[0054] In specific implementation, the limiting block 7 of this embodiment is provided with a cavity structure 702. One end of the cavity structure 702 is open, and the open end is located on the end face of the limiting block 7 that abuts against the abutment protrusion 2032. Thus, by setting the cavity structure 702, the cavity structure 702 provides a certain deformation space for the limiting block 7, which is conducive to the elastic deformation of the end of the limiting block 7 that contacts the abutment protrusion 2032, thereby improving the buffering effect of the limiting block 7.

[0055] Combination Figure 14 As shown, in some exemplary embodiments, the vehicle side panel includes a side panel outer plate 2, which has a sill outer plate 201 extending along the front-rear direction of the vehicle, and a front pillar outer plate 202 and a rear pillar outer plate 203 respectively disposed at the front and rear ends of the sill outer plate 201. A second hinge 3 is disposed between the front pillar outer plate 202 and the door, and the rear pillar outer plate 203 has a protruding portion 2031 extending along the vertical direction of the vehicle, and the bottom end of the protruding portion 2031 bends forward to form an abutment protrusion 2032.

[0056] By mounting the second hinge 3 on the outer panel 202 of the front pillar, the better structural strength of the outer panel 202 is utilized to improve the connection strength of the second hinge 3 on the vehicle body and ensure the load-bearing capacity of the door. Simultaneously, the protruding portion 2031 on the outer panel 203 of the rear pillar enhances the structural strength of the rear pillar outer panel 203 itself. The abutment protrusion 2032, mounted on the protruding portion 2031, improves the limiting effect on the limiting block 7 and eliminates the need for an additional abutment protrusion 2032, simplifying manufacturing. Furthermore, when the limiting block 7 abuts against the abutment protrusion 2032, the abutment protrusion 2032 disperses the impact force from the limiting block 7 to other parts of the vehicle body via the outer panel 203 of the rear pillar and the outer panel 201 of the door sill.

[0057] In a specific implementation, the front pillar outer panel 202 of this embodiment forms the lower end of the A-pillar of the vehicle. The front pillar outer panel 202 includes a vertically extending body and an extension portion 2022 located at the top of the body. The extension portion 2022 extends forward of the vehicle, and the second hinge 3 is fixed to the extension portion 2022. The extension portion 2022 provides structural reinforcement to the body of the front pillar outer panel 202, while also providing sufficient installation space for the second hinge 3, preventing interference between the hinge and other vehicle body components.

[0058] At the same time, combined Figure 1 , Figure 19 As shown, the top of the rear pillar outer panel 203 is connected to the top cover outer panel 8. The top cover outer panel 8 includes a connecting portion that extends vertically and is connected to the rear pillar outer panel 203, and a top cover portion that extends laterally toward the inside of the vehicle body from the top of the connecting portion. The first hinge 1 is installed on the top cover portion.

[0059] Furthermore, in this embodiment, the top of the inner panel 6 is provided with a door upper extension plate 602 extending laterally towards the inside of the vehicle. Simultaneously, the door upper extension plate 602 can overlap the top cover portion of the outer cover panel 8 and is connected to the first hinge 1. Moreover, the door upper extension plate 602 is provided with a boss structure 6021, which supports the outer door panel and provides installation space for other components on the inside of the door. The boss structure 6021 is a closed structure, without any perforations such as mounting holes, to ensure the door's sealing and waterproof performance.

[0060] Specifically, the first hinge 1 in this embodiment includes a hinge seat 101 disposed on the top cover portion, and a hinge arm 102 hinged to the hinge seat 101 and connected to the upper extension plate 602 of the door. The hinge seat 101 has a connecting groove for connecting the hinge arm 102. The connecting end of the hinge arm 102 is disposed in the connecting groove and hinged to the two side walls of the connecting groove to realize the rotational movement of the first hinge 1.

[0061] Combination Figure 5 , Figure 6 As shown, in some exemplary embodiments, the second hinge 3 includes a fixed member 301 disposed on the side panel of the vehicle body and a movable member 302 disposed on the door, the fixed member 301 and the movable member 302 being rotatably connected. An assisting element 9 is provided between the movable member 302 and the bottom end of the side panel of the vehicle body, and the two ends of the assisting element 9 are respectively connected to the movable member 302 and the ball joint of the side panel of the vehicle body.

[0062] The door can be opened and closed through the cooperation of the fixed part 301 and the movable part 302. Meanwhile, an assistive element 9 is provided between the movable part 302 and the side panel of the vehicle body to provide assistance when opening and closing the door, reducing the operating force and improving ease of use. Furthermore, the assistive element 9 uses a ball joint connection, allowing for flexible angle adjustment during door opening and closing to prevent interference with other parts and ensure stable assist effect.

[0063] In specific implementation, the assisting element 9 of this embodiment can be a gas spring, electric strut, or other assisting element 9 well known to those skilled in the art, which can provide assistance to the moving part 302 when the door is opened or closed, thereby effectively reducing the operating force of the door.

[0064] Combination Figures 14 to 18 As shown, in some exemplary embodiments, the movable member 302 includes a main body 3021 connected to the vehicle door, and a hinge arm 3022 provided on the main body 3021. The hinge arm 3022 extends towards the front of the main body 3021 and is hingedly connected to the fixing member 301. The hinge arm 3022 is provided with a mounting protrusion 3023 protruding outward from the vehicle side, and a ball head 3024 provided on the mounting protrusion 3023. The assisting element 9 is provided with a ball socket 901 that mates with the ball head 3024.

[0065] By setting the main body 3021 and the hinge arm 3022, and extending the hinge arm 3022 forward, the range of motion of the second hinge 3 can be expanded, so that the door can open and close along a preset trajectory. Through the cooperation of the ball joint 3024 and the ball socket 901, the power assist element 9 can move at multiple angles, avoiding interference and jamming when the door is opened and closed, and further improving the smoothness of the door opening and closing and the stability of the power assist effect.
