Description

Technical Field

[0001] This application relates to, but is not limited to, the field of door structures, and in particular to a door assembly and a vehicle. Background Technology

[0002] Traditional car rear doors typically open either by rotating or sliding. Rotating doors generally open laterally along the door hinge axis; sliding doors rely on a guide rail to slide the door towards the rear of the vehicle. Additionally, some vehicles use gull-wing doors to enhance their technological appeal and attractiveness to users, but gull-wing doors are now quite common.

[0003] Some vehicles use a combination of gull-wing doors and revolving doors or other types of doors. However, there are issues such as poor sealing at the contact points between the gull-wing doors and revolving doors, incomplete closure, and unsmooth door opening and closing, which affect vehicle performance. Summary of the Invention

[0004] This application provides a door assembly and a vehicle with a novel and technologically advanced opening method and a tight door seal.

[0005] This application provides a vehicle door assembly, which includes a first door body, a second door body, and a guide rail. The first door body is rotatably mounted on the vehicle body, and the second door body is slidably mounted on the vehicle body. The second door body is located below the first door body in the height direction.

[0006] The guide rail includes a front guide rail disposed at the free end of the first door body and a rear guide rail disposed on the vehicle body. The rear guide rail is connected to the front guide rail to form a complete track for sliding of the second door body.

[0007] The front end of the rear guide rail is provided with a guide plate for docking with the front guide rail.

[0008] Furthermore, the guide plate includes an abutment plate and limiting plates disposed on both sides of the abutment plate. The abutment plate is configured to cooperate with the rear end of the front guide rail, and the limiting plates are configured to guide and limit the rear end of the front guide rail.

[0009] Furthermore, the abutment plate is a U-shaped plate, and the U-shaped opening on the abutment plate is used to avoid the groove on the rear guide rail.

[0010] Furthermore, in the direction along the rear end of the front guide rail into the guide plate, the gap between the two limiting plates gradually decreases.

[0011] Furthermore, a guide block is provided at the rear end of the front guide rail;

[0012] When the guide block and the front guide rail rotate to the closed position of the first door, the guide block is limited by the guide plate, and the rear guide rail is aligned and connected with the front guide rail to form the complete track.

[0013] Furthermore, the rear guide rail is rotatably fixed to the vehicle body;

[0014] The guide block is a U-shaped component. When the guide block enters the position between the two limiting plates, the rear guide rail can rotate to achieve position adjustment.

[0015] Furthermore, the door assembly also includes a fixing bracket, one end of which is mounted on the vehicle body and the other end is rotatably connected to the rear guide rail;

[0016] The fixed bracket is provided with a limiting part, which restricts the rear guide rail from rotating within a preset angle range.

[0017] Furthermore, one end of the fixed bracket is bent to form a baffle, which serves as the limiting part;

[0018] The fixed bracket and the top of the U-shaped rear guide rail are connected by a connecting shaft. The rear guide rail can rotate in the horizontal direction. The baffle is set on the side of the rear guide rail away from the vehicle body, and there is a gap between the baffle and the rear guide rail, so that the rear guide rail can rotate within a preset angle range.

[0019] Furthermore, a first U-shaped groove is provided on the front guide rail, and the guide block is sleeved on the rear end of the front guide rail, with the U-shaped opening of the guide block communicating with the first U-shaped groove;

[0020] The rear guide rail is provided with a second U-shaped groove. After the rear guide rail is connected to the guide block, the second U-shaped groove communicates with the U-shaped opening of the guide block.

[0021] Furthermore, the guide plate and the guide block may also have at least one of the following features:

[0022] The side of the abutment plate and the limiting plate facing the guide block is set as a smooth surface;

[0023] The guide plate is made of a self-lubricating material;

[0024] The guide block is made of a self-lubricating material.

[0026] The vehicle body is provided with a first installation area and a second installation area that are connected. The first door is installed in the first installation area and the second door is installed in the second installation area.

[0027] Furthermore, the first mounting area is located on the top surface of the vehicle body, and the second mounting area is located on the side surface of the vehicle body;

[0028] The first door and the second door are combined to form the rear door on the vehicle body.

[0029] Compared to some other technologies, this application has the following advantages:

[0030] The vehicle door assembly provided in this application embodiment is divided into a first door body and a second door body, which are relatively independent. The first door body rotates to open, while the second door body slides to open. This novel and technologically advanced opening method enhances the vehicle's appeal to users. Furthermore, opening the first door body increases the door opening space, eliminating the need for users to bend over or stoop when getting in and out of the vehicle, making it easier for them to enter and exit. The vehicle can still be opened normally in smaller spaces (such as alleys or garages), facilitating user entry and exit. A front guide rail is provided at the free end of the first door body, and a rear guide rail is provided on the vehicle body for the sliding of the second door body. A guide plate is provided on the rear guide rail to align with the front guide rail, providing guidance and ensuring quick and precise alignment between the front and rear guide rails. This results in smooth sliding of the second door body, high closing accuracy, and the guide rails also provide a certain degree of sealing and limiting, improving the overall sealing performance of the vehicle door assembly.

[0031] The vehicle provided in this application embodiment has the aforementioned door assembly, featuring a novel and technologically advanced opening method that enhances its appeal to users. Furthermore, users can get in and out of the vehicle without bending or stooping, resulting in a superior user experience. The vehicle can also be opened normally in confined spaces, improving its practicality. The overall sealing performance of the vehicle is excellent, leading to high user satisfaction.

Detailed Implementation

[0045] To make the objectives, technical solutions, and advantages of this application clearer, the embodiments of this application will be described in detail below with reference to the accompanying drawings. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be arbitrarily combined with each other.

[0046] This application provides a vehicle door assembly, which includes a first door body 1, a second door body 2, and a guide rail. The first door body 1 is rotatably mounted on the vehicle body 3, and the second door body 2 is slidably mounted on the vehicle body 3, with the second door body 2 located below the first door body 1 in the height direction. The guide rail includes a front guide rail 11 disposed at the free end of the first door body 1 and a rear guide rail 35 disposed on the vehicle body 3. The rear guide rail 35 is connected to the front guide rail 11 to form a complete track for the sliding of the second door body 2. The front end of the rear guide rail 35 is provided with a guide plate 5 for connecting with the front guide rail 11.

[0047] The first door 1 can be in the form of a gull-wing door, which is rotatably mounted on the vehicle body 3, such as at the top of the vehicle body 3; the second door 2 can be in the form of a sliding door, which is slidably mounted on the vehicle body 3 by cooperating with the front guide rail 11 on the first door 1 and the rear guide rail 35 on the vehicle body 3.

[0048] The first door 1, located at the top of the vehicle body 3, significantly increases the opening space after opening, allowing passengers to enter and exit the vehicle without bending over, greatly improving the convenience of rear passengers getting in and out. The second door 2 opens by sliding, meaning it moves along the length direction (X direction) of the vehicle; and the rotation of the first door 1 at the top of the vehicle body 3 does not occupy space in the width direction (Y direction), requiring little space to open the door, making it easy to open in narrow alleys or garages, convenient and practical. Furthermore, when the door is closed, the front guide rail 11, in conjunction with the second door 2, provides a certain limit to the first door 1, preventing it from opening accidentally. The direct guide rail connection structure between the first door 1 and the second door 2 greatly improves the stability of the door and the sealing of the entire system. The front guide rail 11 and the rear guide rail 35 are joined to form a complete track for the sliding of the second door 2, so that the second door 2 can slide smoothly. In addition, the cooperation between the front guide rail 11 and the second door 2 can improve the sealing performance between the first door 1 and the second door 2. The front guide rail 11 can also limit the second door 2.

[0049] In practical applications, regarding the opening method of the door assembly, when opening the door, the second door 2 firstly slides open, and then the first door 1 rotates open; when closing the door, the first door 1 firstly rotates close, and then the second door 2 slides close. The opening control of the first door 1 and the second door 2 can be automatically achieved through a preset program, or it can be manually achieved by the driver or passenger; this application does not limit this.

[0050] The front guide rail 11 can be fixed to the first door body 1 by spot welding, riveting or other methods, or it can be formed directly by integral molding.

[0051] The front end of the rear guide rail 35 is provided with a guide plate 5 for docking with the front guide rail 11. The guide plate 5 plays a guiding role in the docking process of the front guide rail 11 and the rear guide rail 35, so that the docking of the front guide rail 11 and the rear guide rail 35 is fast and accurate, improving the response speed and facilitating the sliding of the second door 2.

[0052] The door assembly provided in this application provides that by distributing the upper guide rail of the original sliding door to the free end of the gull-wing door and the body 3 (i.e., the front guide rail 11 and the rear guide rail 35), the second door 2 can still slide through three guide rails. This eliminates the need to reduce the number of guide rails due to the complex structure of the upper part of the second door 2 and the inability to set guide rails, thus ensuring the reliability and smoothness of the sliding of the second door 2.

[0053] In an exemplary embodiment, the guide plate 5 includes an abutment plate 51 and limiting plates 52 disposed on both sides of the abutment plate 51. The abutment plate 51 is configured to cooperate with the rear end of the front guide rail 11, and the limiting plates 52 are configured to guide and limit the rear end of the front guide rail 11.

[0054] The abutment plate 51 is used to abut against the rear end of the front guide rail 11 along its length, and the limiting plates 52 on both sides are used to limit the rear end of the front guide rail 11 in the horizontal direction, so that the front guide rail 11 and the rear guide rail 35 with the guide plate 5 form a complete track, so that the second door 2 can slide.

[0055] In practical applications, the guide plate 5 can be set at a certain tilt angle in the vertical direction to prevent the front guide rail 11 from failing to enter between the two limiting plates 52 when it rotates and falls. In other words, the tilted setting of the guide plate 5 can also play a certain guiding role. Furthermore, the tilted guide plate 5 can provide a certain degree of support and limit the front guide rail 11 in the vertical direction.

[0056] In an exemplary embodiment, the abutment plate 51 is a U-shaped plate, and the U-shaped opening on the abutment plate 51 is used to avoid the groove on the rear guide rail 35.

[0057] The abutment plate 51 is a U-shaped plate, that is, a U-shaped opening is opened on the abutment plate 51 to avoid blocking the sliding groove on the rear guide rail 35, so that the front guide rail 11 and the rear guide rail 35 are connected to form a connected sliding groove, so that the sliding component of the second door 2 can slide in the complete sliding groove.

[0058] It should be understood that the abutment plate 51 can also be of other shapes, as long as it can avoid the groove on the rear guide rail 35 while ensuring its normal abutment, limiting and guiding functions. This application does not limit this.

[0059] In an exemplary embodiment, the gap 45 between the two limiting plates 52 gradually decreases in the direction along the rear end of the front guide rail 11 into the guide plate 5.

[0060] In other words, the two limiting plates 52 form an opening structure that is "larger at the top and smaller at the bottom". The larger opening at the top makes it easier for the rear end of the front guide rail 11 to be inserted, while the smaller opening at the bottom can support and limit the inserted rear end of the front guide rail 11.

[0061] In an exemplary embodiment, a guide block 111 is provided at the rear end of the front guide rail 11; when the guide block 111 and the front guide rail 11 rotate with the first door body 1 to the closed position of the first door body 1, the guide block 111 is limited by the guide plate 5, and the rear guide rail 35 is aligned and connected with the front guide rail 11 to form a complete track.

[0062] When the front guide rail 11 and the rear guide rail 35 are connected, in order to facilitate the successful connection and improve the stability of the connection, a guide block 111 is set at the rear end of the front guide rail 11 to cooperate with the guide plate 5. When the first door 1 is closed, the guide block 111 and the guide plate 5 are limited to cooperate, so that the rear guide rail 35 and the front guide rail 11 are connected to form a complete guide rail, so as to facilitate the sliding of the second door 2.

[0063] The guide block 111 is set to facilitate the limiting and matching of the guide plate 5, which effectively improves the docking accuracy of the front guide rail 11 and the rear guide rail 35, avoids deviation after the front guide rail 11 and the rear guide rail 35 dock, which would cause the second door 2 to slide poorly, ensures smooth opening and closing of the door, and also avoids wear on the rear end of the front guide rail 11, thereby extending the service life of the guide rail.

[0064] In an exemplary embodiment, the rear guide rail 35 is rotatably fixed to the vehicle body 3; the guide block 111 is a U-shaped part, and the rear guide rail 35 can rotate to achieve position adjustment when the guide block 111 enters the position between the two limiting plates 52.

[0065] The rear guide rail 35 is rotatably fixed to the vehicle body 3. When the guide block 111 mates with the guide plate 5, the rear guide rail 35 can rotate to align with the guide block 111 and adjust the position between the guide block 111 and the guide plate 5. This facilitates the guide block 111 entering the limiting area of ​​the guide plate 5 and prevents the rear guide rail 35 from failing to mate due to positional deviation. The rotatable nature of the rear guide rail 35 allows it to automatically adjust its position during the mate process to facilitate the limiting engagement between the limiting block and the limiting plate 52, making it simple and reliable.

[0066] Both the front guide rail 11 and the rear guide rail 35 are U-shaped pieces with downward openings. The sliding mechanism on the door (such as the upper hinge assembly 21) is slidably installed in the opening of the front guide rail 11 or the rear guide rail 35 for sliding. Correspondingly, the guide block 111 is also configured as a U-shaped piece with downward openings. The guide block 111 can be sleeved on the rear end of the front guide rail 11 and can partially extend out of the rear end of the front guide rail 11 so as to cooperate and connect with the guide plate 5.

[0067] In an exemplary embodiment, the door assembly further includes a fixing bracket 4, one end of which is mounted on the vehicle body 3 and the other end is rotatably connected to the rear guide rail 35; the fixing bracket 4 is provided with a limiting part 43, which restricts the rear guide rail 35 from rotating within a preset angle range.

[0068] The rear guide rail 35 is rotatably mounted on the vehicle body 3 via a fixed bracket 4. The fixed bracket 4 is provided with a limiting part 43 for limiting the rotation angle of the rear guide rail 35, so that the rear guide rail 35 can rotate within a certain angle range, preventing the rear guide rail 35 from deviating and failing to connect with the guide block 111 due to excessive rotation angle.

[0069] One end of the fixed bracket 4 can be equipped with a welding point, which can be fixedly connected to the vehicle body 3 by spot welding.

[0070] In an exemplary embodiment, one end of the fixed bracket 4 is bent to form a baffle, which serves as a limiting part 43; the fixed bracket 4 and the top of the U-shaped rear guide rail 35 are connected by a connecting shaft, the rear guide rail 35 can rotate in the horizontal direction, the baffle is disposed on the side of the rear guide rail 35 away from the vehicle body 3, and there is a gap 45 between the baffle and the rear guide rail 35, so that the rear guide rail 35 can rotate within a preset angle range.

[0071] One end of the fixed bracket 4 is bent to form a baffle. In other words, the limiting part 43 is a baffle structure. The baffle is simple in form and easy to set. There is no need to add an extra component as the limiting part 43, which simplifies the structure of the fixed bracket 4 and improves the overall reliability of the door assembly.

[0072] A gap 45 is provided between the baffle and the rear guide rail 35. When the rear guide rail 35 rotates and comes into contact with the baffle, it is limited to a certain range of rotation and will not exceed it. In practical applications, the size of the gap 45 can be adjusted to regulate the range of rotation of the rear guide rail 35.

[0073] The fixed bracket 4 is connected to the top of the U-shaped rear guide rail 35 via a connecting shaft, allowing the rear guide rail 35 to rotate horizontally within a certain range relative to the fixed bracket 4. The connecting shaft at the top of the rear guide rail 35 does not affect the sliding mechanism located within the U-shaped opening.

[0074] The fixed bracket 4 includes a mounting section 41, a connecting section 42, and a limiting part 43. The mounting section 41 is connected to the vehicle body 3, and the limiting part 43 is connected to the mounting section 41 via the connecting section 42. The connecting section 42 has a mounting hole 421, and the rear guide rail 35 is mounted at the mounting hole 421 via a rotating pin 44. The mounting section 41 is configured to be connected to the vehicle body 3; that is, welding points can be located on the mounting section 41, and the mounting section 41 is fixedly connected to the vehicle body 3 by spot welding. The limiting part 43 can be a baffle formed by bending at the end of the connecting section 42. The rear guide rail 35 is rotatably connected to the connecting section 42 via the rotating pin 44 in the mounting hole 421, and its rotation is limited to a certain angle range by the limiting part 43. In practical applications, the fixed bracket 4 can be a sheet-like structure, and both the mounting section 41 and the connecting section 42 can be flat structures, located on the same plane or different planes. The limiting part 43 may be formed by bending the end of the connecting section 42, that is, the limiting part 43 may be a baffle perpendicular to the connecting section 42.

[0075] In an exemplary embodiment, a first U-shaped groove is provided on the front guide rail 11, and a guide block 111 is sleeved on the rear end of the front guide rail 11, with the U-shaped opening of the guide block 111 communicating with the first U-shaped groove; a second U-shaped groove is provided on the rear guide rail 35, and after the rear guide rail 35 is connected to the guide block 111, the second U-shaped groove communicates with the U-shaped opening of the guide block 111.

[0076] After the first U-shaped groove and the second U-shaped groove are connected, a complete sliding groove for the sliding mechanism is formed, and the front guide rail 11 and the rear guide rail 35 are connected to form a complete guide rail.

[0077] By using a U-shaped groove, the Y-direction (width direction of the vehicle body 3) movement of the sliding mechanism on the second door body 2 can be restricted, allowing the second door body 2 to slide along the X-direction (length direction of the vehicle body 3) to open or close the door.

[0078] The door assembly also includes an upper hinge assembly 21, one end of which is mounted on the upper part of the second door body 2, and the other end slides in the complete track formed by the first U-shaped groove and the second U-shaped groove. The upper hinge assembly 21 serves as a sliding mechanism on the upper part of the second door body 2, allowing the second door body 2 to slide against the vehicle body 3 in the X direction. Furthermore, the door assembly may also include a lower hinge assembly 22 located at the lower end of the second door body 2, and a middle hinge assembly 23 located in the height direction between the upper hinge assembly 21 and the lower hinge assembly 22; the vehicle body 3 is provided with a first guide rail 33 that cooperates with the lower hinge assembly 22, and a second guide rail 34 that cooperates with the middle hinge assembly 23. The second door body 2 may have three sliding structures for sliding cooperation with the guide rails: the upper hinge assembly 21, the middle hinge assembly 23, and the lower hinge assembly 22. The front guide rail 11, which mates with the upper hinge assembly 21, is located at the free end of the first door body 1. The first guide rail 33, which mates with the lower hinge assembly 22, and the second guide rail 34, which mates with the middle hinge assembly 23, are both located on the vehicle body 3. The front guide rail 11, the first guide rail 33, and the second guide rail 34 can be guide rails with a certain curvature at their ends. The guide rails taper inward along the width direction (Y direction) of the vehicle body 3 to facilitate the sliding of the second door body 2 along each guide rail. Finally, the second door body 2 is inserted into the opening position on the vehicle body 3 to close smoothly. The upper hinge assembly 21, the middle hinge assembly 23, and the lower hinge assembly 22 can be installed on the second door body 2 by bolt fixing. The first guide rail 33 and the second guide rail 34 can be installed on the vehicle body 3 by bolt fixing.

[0079] In an exemplary embodiment, the guide plate 5 and the guide block 111 may also have at least one of the following features: the side of the abutment plate 51 and the limiting plate 52 facing the guide block 111 is provided as a smooth surface; the guide plate 5 is made of a self-lubricating material; the guide block 111 is made of a self-lubricating material.

[0080] The guide block 111 or some structures on the guide block 111 can be provided to improve the guiding effect. For example, both the abutment plate 51 and the limiting plate 52 have smooth surfaces to reduce the friction when the guide block 111 contacts the guide plate 5, making it easier for the guide block 111 to enter the limiting area of ​​the guide plate 5; the guide block 111 is made of a self-lubricating material to reduce the friction when the guide block 111 contacts the rear guide rail 35, making it easier for the front end of the rear guide rail 35 to enter the U-shaped opening of the guide block 111; of course, the guide plate 5 can also be made of a self-lubricating material.

[0081] In addition, the door assembly may also include the following features:

[0082] like Figure 5As shown, a sliding mechanism is provided on the second door body 2. The sliding mechanism includes an upper hinge assembly 21 located at the upper end of the second door body 2, which is configured to slide within the first guide rail 11. The second door body 2 is slidably mounted on the vehicle body 3. The second door body 2 slides through the upper hinge assembly 21 and the first guide rail 11 to improve the reliability and smoothness of the sliding of the second door body 2. Specifically, the upper hinge assembly 21 may include a roller, which is mounted on the second door body 2 via a hinge structure and slides within the first guide rail 11.

[0083] like Figure 4 As shown, the first door 1 is mounted on the top of the vehicle body 3 via a rotating mechanism 14. The rotating mechanism 14 includes a rotating hinge 141 and a telescopic strut 142. The hinged end of the first door 1 is connected to the vehicle body 3 via the rotating hinge 141. One end of the telescopic strut 142 is connected to the first door 1, and the other end is connected to the vehicle body 3. The telescopic strut 142 drives the first door 1 to rotate around the rotating hinge 141. The rotating hinge 141 enables the first door 1 to rotate relative to the vehicle body 3. The telescopic strut 142 extends or retracts to drive the first door 1 to rotate. In other words, by controlling the extension and retraction of the telescopic strut 142, the opening or closing of the first door 1 is achieved. The two ends of the telescopic strut 142 can be connected to the vehicle body 3 and the first door 1 respectively by bolts. The telescopic strut 142 can be connected to a drive device, and automatic control of the telescopic strut 142, i.e., automatic opening and closing of the first door 1, can be achieved through mechanisms such as a motor.

[0084] like Figure 4 As shown, the first door 1 includes a door sheet metal 12 and a light-transmitting element 13 mounted on the door sheet metal 12. Two telescopic support rods 142 are provided, located on either side of the light-transmitting element 13. Parts of the door sheet metal 12 on either side of the light-transmitting element 13 partially obscure the telescopic support rods 142. The light-transmitting element 13 can be glass or other components, improving the field of vision inside the vehicle. The light-transmitting element 13 can be located in the middle of the door sheet metal 12. The telescopic support rods 142 are located on either side of the light-transmitting element 13 to avoid obstructing the light-transmitting element 13 and affecting the field of vision. Simultaneously, the door sheet metal 12 on either side of the light-transmitting element 13 can obscure the telescopic support rods 142, preventing them from being directly seen from outside the vehicle and improving the vehicle's aesthetics. It should be understood that the light-transmitting element 13 may not be provided on the first door body 1. In other words, the first door body 1 may be a complete sheet metal part without glass. In this case, the setting position of the telescopic support rod 142 does not need to consider obstruction and avoidance, and the setting position of the telescopic support rod 142 can be adjusted according to the needs. This application does not limit this.

[0085] The door assembly provided in this application not only serves as an exterior and moving part of the vehicle, ensuring aesthetics, safety, and sealing, and providing basic functions such as passenger access, but also plays a role in attracting attention and creating a sense of ceremony, thus enriching the functions of the door assembly.

[0086] This application embodiment also provides a vehicle, which includes a body 3 and a front door assembly; the body 3 is provided with a first mounting area 31 and a second mounting area 32 that are connected, the first door 1 is installed in the first mounting area 31, and the second door 2 is installed in the second mounting area 32.
