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] Furthermore, a guide block is provided at the rear end of the front guide rail, and the guide block is provided with a limit groove;

[0008] When the guide block and the front guide rail rotate to the closed position of the first door, the front end of the rear guide rail enters the limiting groove of the guide block, so that the rear guide rail and the front guide rail are aligned and connected to form the complete track.

[0009] Furthermore, the rear guide rail is rotatably fixed to the vehicle body;

[0010] The front guide rail, rear guide rail, and guide block are all U-shaped pieces with downward openings. When the front end of the rear guide rail enters the limiting groove of the guide block, it can rotate to achieve position adjustment.

[0011] 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;

[0012] The fixed bracket is provided with a limiting part, which restricts the rear guide rail from rotating within a preset angle range.

[0013] Furthermore, one end of the fixed bracket is bent to form a baffle, which serves as the limiting part;

[0014] 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.

[0015] Furthermore, the fixed bracket includes an installation section, a connecting section, and a limiting part; the installation section is connected to the vehicle body, and the limiting part is connected to the installation section through the connecting section.

[0016] The connecting section is provided with mounting holes, and the rear guide rail is mounted at the mounting holes by means of a rotating pin.

[0017] 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;

[0018] 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.

[0019] Furthermore, the door assembly also includes an upper hinge assembly, one end of which is mounted on the upper part of the second door body, and the other end of which slides in the complete track formed by the first U-shaped groove and the second U-shaped groove.

[0020] Furthermore, the guide block may also have at least one of the following features:

[0021] The guide block has a guide ramp at its U-shaped opening;

[0022] The inner wall of the guide block is made into a smooth surface;

[0023] The guide block is made of a self-lubricating material.

[0024] Furthermore, the first door is a gull-wing door, and the second door is a sliding door.

[0025] This application also provides a vehicle, which includes a vehicle body and the aforementioned door assembly;

[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, thus facilitating entry and exit. The vehicle can still be opened normally in confined spaces (such as alleyways or garages), further simplifying 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. The second door body slides smoothly, has high closing precision, 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.

[0032] Other features and advantages of this application will be set forth in the following description. Attached Figure Description

Detailed Implementation

[0044] 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.

[0045] This application provides a door assembly, such as... Figures 1 to 8 As shown, the door assembly 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.

[0046] 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.

[0047] 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.

[0048] 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.

[0049] 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.

[0050] 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.

[0051] In one exemplary embodiment, such as Figure 7 and Figure 8 As shown, a guide block 111 is provided at the rear end of the front guide rail 11, and the guide block 111 is provided with a limiting groove 112; 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 front end of the rear guide rail 35 enters the limiting groove 112 of the guide block 111, so that the rear guide rail 35 and the front guide rail 11 are aligned and connected to form a complete track.

[0052] 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. When the first door 1 is closed, the front end of the rear guide rail 35 enters the limiting groove 112 of the guide block 111, thereby connecting the rear guide rail 35 with the front guide rail 11 to form a complete guide rail, so as to facilitate the sliding of the second door 2.

[0053] The limiting groove 112 of the guide block 111 can be slightly larger than the size of the front end of the rear guide rail 35 so that the rear guide rail 35 can enter and there will be no large swing after the rear guide rail 35 enters the limiting groove 112.

[0054] The guide block 111 is set up to effectively improve the docking accuracy of the front guide rail 11 and the rear guide rail 35, and avoid deviations after the front guide rail 11 and the rear guide rail 35 are docked, which would cause the second door body 2 to slide poorly, thus ensuring smooth opening and closing of the car door.

[0055] In an exemplary embodiment, the rear guide rail 35 is rotatably fixed to the vehicle body 3; the front guide rail 11, the rear guide rail 35 and the guide block 111 are all U-shaped parts with downward openings, and the front end of the rear guide rail 35 can rotate to achieve position adjustment when it enters the limiting groove 112 of the guide block 111.

[0056] The rear guide rail 35 is rotatably fixed to the vehicle body 3. When the rear guide rail 35 mates with the guide block 111, it can rotate to align with the limiting groove 112 of the guide block 111, adjusting the position between the rear guide rail 35 and the limiting groove 112. This facilitates the front end of the rear guide rail 35 entering the limiting groove 112 of the guide block 111, preventing 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 to enter the limiting groove 112 of the guide block 111 during the mate process, making it simple and reliable.

[0057] 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 fitted onto the rear end of the front guide rail 11 and can partially extend beyond the rear end of the front guide rail 11 for connection with the rear guide rail 35.

[0058] In one exemplary embodiment, such as Figures 7 to 8 As shown, the door assembly also includes a fixed bracket 4, one end of which is mounted on the body 3 and the other end is rotatably connected to the rear guide rail 35; a limiting part 43 is provided on the fixed bracket 4, which restricts the rear guide rail 35 from rotating within a preset angle range.

[0059] 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.

[0060] 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.

[0061] In one exemplary embodiment, such as Figure 8 As shown, 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 set 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.

[0062] 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.

[0063] 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.

[0064] 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.

[0065] In one exemplary embodiment, such as Figure 8 As shown, the fixed bracket 4 includes an installation section 41, a connecting section 42, and a limiting part 43. The installation section 41 is connected to the vehicle body 3, and the limiting part 43 is connected to the installation section 41 through the connecting section 42. The connecting section 42 is provided with an installation hole 421, and the rear guide rail 35 is installed at the installation hole 421 through a rotating pin 44.

[0066] Mounting section 41 is configured to be connected to the vehicle body 3, that is, the welding point can be set on mounting section 41, and mounting section 41 is fixedly connected to vehicle body 3 by spot welding. Limiting part 43 can be a baffle formed by bending at the end of connecting section 42. Mounting hole 421 is provided on connecting section 42, and rear guide rail 35 is rotatably connected to connecting section 42 by rotating pin 44 and is restricted to rotating within a certain angle range by limiting part 43.

[0067] In practical applications, the fixing bracket 4 can be a sheet-like structure, and both the mounting section 41 and the connecting section 42 can be flat plate structures, located on the same plane or different planes. The limiting part 43 can be formed by bending the end of the connecting section 42, that is, the limiting part 43 can be a baffle perpendicular to the connecting section 42.

[0068] 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.

[0069] 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.

[0070] 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.

[0071] In one exemplary embodiment, such as Figure 5 As shown, 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.

[0072] One end of the upper hinge assembly 21 is installed on the upper part of the second door body 2 as a sliding mechanism, so that the second door body 2 can slide relative to the vehicle body 3 in the X direction.

[0073] In addition, 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 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.

[0074] The second door body 2 can be provided with three sliding structures for sliding cooperation with the guide rails, namely: upper hinge assembly 21, middle hinge assembly 23, and lower hinge assembly 22. The front guide rail 11, which cooperates with the upper hinge assembly 21, is located at the free end of the first door body 1, and the first guide rail 33, which cooperates with the lower hinge assembly 22, and the second guide rail 34, which cooperates with the middle hinge assembly 23, are both located on the vehicle body 3.

[0075] 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 the end. The guide rails contract inward along the width direction (Y direction) of the vehicle body 3 so that the second door 2 can slide along each guide rail. Finally, the second door is embedded in the opening position on the vehicle body 3 to close smoothly.

[0076] 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 bolts. The first guide rail 33 and the second guide rail 34 can be installed on the vehicle body 3 by bolts.

[0077] In an exemplary embodiment, the guide block 111 may also have at least one of the following features: a guide ramp is provided at the U-shaped opening of the guide block 111; the inner wall of the guide block 111 is provided as a smooth surface; and the guide block 111 is made of a self-lubricating material.

[0078] The guide block 111 may be provided with certain structures to improve the guiding effect, such as: a guide ramp is provided at the U-shaped opening of the guide block 111, which makes it easier for the front end of the rear guide rail 35 to enter the U-shaped opening of the guide block 111; the inner wall of the guide block 111 is made into a smooth surface 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; 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.

[0079] It should be understood that, in addition to modifying the guide block 111, the front end of the rear guide rail 35 can also be modified to make it easier for the front end of the rear guide rail 35 to enter the U-shaped opening of the guide block 111, such as setting the front end of the rear guide rail 35 to a smooth surface.

[0080] In addition, the door assembly may also have the following features:

[0081] In one exemplary embodiment, such as Figures 1 to 3 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.

[0082] The hinge 141 rotates the first door 1 relative to the vehicle body 3. The telescopic strut 142 extends or retracts to drive the first door 1 to rotate. In other words, the opening or closing of the first door 1 is achieved by controlling the extension and retraction of the telescopic strut 142. The two ends of the telescopic strut 142 can be connected to the vehicle body 3 and the first door 1 respectively by bolts.

[0083] The telescopic strut 142 can be connected to a drive device, and automatic control of the telescopic strut 142 can be achieved through a motor or other mechanism, that is, automatic opening and closing of the first door 1.

[0084] like Figure 4 As shown, the first door body includes a door sheet metal 12 and a light-transmitting element 13 disposed on the door sheet metal 12; the number of telescopic support rods 142 is set to two and located on both sides of the light-transmitting element 13 respectively, and the door sheet metal 12 on both sides of the light-transmitting element 13 blocks the telescopic support rods 142.

[0085] This application embodiment also provides a vehicle, the vehicle including a body 3 and the aforementioned door assembly; the body 3 is provided with a first mounting area 31 and a second mounting area 32 that are connected, such as... Figure 1 As shown, the first door 1 is installed in the first installation area 31, and the second door 2 is installed in the second installation area 32.

[0086] The first installation area 31 and the second installation area 32 form a complete opening in the vehicle body 3, which is the entrance and exit for users to get on and off the vehicle. The first door 1 is installed in the first installation area 31, and the second door 2 is installed in the second installation area 32, forming a complete door.

[0087] In one exemplary embodiment, such as Figure 1 As shown, the first mounting area 31 is located on the top surface of the vehicle body 3, and the second mounting area 32 is located on the side of the vehicle body 3; the first door body 1 and the second door body 2 are combined to form the rear door on the vehicle body 3.

[0088] When the second door 2 slides open and the first door 1 rotates open, the first installation area 31 located above the user's head is no longer obstructed by the first door 1, allowing the user to get on and off the vehicle without bending down, which is convenient. The second door 2 slides open backward, without occupying space in the width direction of the vehicle body 3, allowing for opening and getting on and off the vehicle in narrow alleys and other spaces, making it highly practical.

[0089] It should be understood that the door assembly provided in this application embodiment can be used as a rear door or a front door. The shape of the door assembly can be adjusted according to the specific installation position, and this application does not limit this.

[0090] When applied to specific vehicles, the first door 1 can be a gull-wing door, and the second door 2 can be a sliding door, which realizes the simultaneous rearward and upward opening of the doors. The opening method is novel and technologically advanced. At the same time, rear passengers do not need to bend down to get in the car. The lateral space occupied after the door is opened is small, and the car can be opened smoothly even in narrow alleys.

[0091] In an exemplary embodiment, there are two first mounting areas 31 and two second mounting areas 32; a partition area is provided at the middle position of the top of the vehicle body 3, and a first mounting area 31 is provided on each side of the partition area. Each first mounting area 31 is connected to a second mounting area 32, and the second mounting areas 32 are located on opposite sides of the vehicle body 3.

[0092] The door assemblies are installed on the left and right sides of the vehicle body 3 to form the left rear door and the right rear door.

[0093] In one exemplary embodiment, such as Figure 1 As shown, a rear guide rail 35 is provided on the vehicle body 3, and the rear guide rail 35 is located on one side of the connection between the first installation area 31 and the second installation area 32, and docks with the front guide rail 11 when the first door is closed to form a complete track for the sliding of the second door body 2.

[0094] The front guide rail 11 can be connected to the rear guide rail 35 to form a complete track for the sliding of the second door 2. When the door is open and closed: when the door is fully closed, the upper hinge assembly 21 is located in the front guide rail 11 of the first door 1; when the door is to be opened, the second door 2 slides open first, and then the first door 1 rotates open, and the upper hinge assembly 21 slides with the second door 2, entering the rear guide rail 35 from the front guide rail 11 to facilitate the opening of the first door 1; when the door is to be closed, the first door 1 rotates close first, and then the second door 2 slides close, and the upper hinge assembly 21 slides with the second door 2, entering the front guide rail 11 from the rear guide rail 35.
