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 the door opens smoothly and steadily.

[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 the second door body.

[0007] A transition piece is provided in the groove of the guide rail. The transition piece is used to allow the sliding piece located in the groove to smoothly slide across the mating gap between the front guide rail and the rear guide rail.

[0008] Furthermore, the transition piece is slidably mounted within the groove of the rear guide rail;

[0009] The transition member slides within the rear guide rail along with the slider; the transition member can partially extend into the front guide rail to cover the mating gap between the front guide rail and the rear guide rail, allowing the slider to slide smoothly within the front and rear guide rails.

[0010] Furthermore, the transition member includes a receiving section and an extension section, and when the transition member slides with the sliding member, the sliding member is located in the cavity formed by the receiving section;

[0011] The extension section is configured as two, with the first end of each extending toward the front guide rail and the second end of each connecting to the receiving section; the channel formed by the two extension sections arranged side by side communicates with the cavity of the receiving section, and the sliding member enters the front guide rail from the cavity through the channel.

[0012] Furthermore, the opening size of the cavity communicating with the channel is smaller than the size of the slider, so that the slider drives the transition piece to slide toward the front guide rail;

[0013] The slider can abut against the side wall of the receiving section away from the opening, so that the slider drives the transition piece to slide in a direction away from the front guide rail.

[0014] Furthermore, a first limiting protrusion is provided on the inner wall of the groove of the rear guide rail, and a recessed area is formed at the connection between the extension section and the receiving section;

[0015] When the transition piece slides to its limit position near the front guide rail, the first limiting protrusion engages with the recessed area to restrict the bidirectional movement of the transition piece.

[0016] Furthermore, when the transition piece slides to its limit position near the front guide rail, the first end of the extension section abuts against the inner wall of the groove of the rear guide rail.

[0017] Furthermore, a guide groove is provided on the wall of the rear guide rail, and a second limiting protrusion is provided on the transition member. The second limiting protrusion is located in the guide groove, so that the transition member slides along the length direction of the rear guide rail with the sliding member.

[0018] 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;

[0019] 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.

[0020] 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;

[0021] 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.

[0022] The mating gap is formed between the first U-shaped groove and the second U-shaped groove.

[0023] 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 is provided with a sliding member for sliding in the complete track formed by the first U-shaped groove and the second U-shaped groove.

[0024] This application also provides a vehicle, which includes a vehicle body and the aforementioned door assembly;

[0025] 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.

[0026] 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;

[0027] The first door is a gull-wing door, and the second door is a sliding door. The first door and the second door are combined to form the rear door of the vehicle body.

[0028] Compared to some other technologies, this application has the following advantages:

[0029] 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 alleyways or garages), facilitating user entry and exit. A transition piece is provided within the guide rail, providing support when the sliding member passes through the gap between the front and rear guide rails, allowing the sliding member to glide smoothly. This, in turn, ensures the second door body slides smoothly and steadily throughout the guide rails, preventing any jamming when the second door body slides through the gap and improving the feel and smoothness of opening and closing the door.

[0030] 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. The user experiences a superior feel when opening and closing the door, with smooth and stable operation, thus improving the vehicle's practicality. The vehicle also boasts excellent overall sealing performance, resulting in high user satisfaction.

Detailed Implementation

[0048] 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.

[0049] Example 1

[0050] This application provides a door assembly, such as... Figures 1 to 13 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. A transition piece 5 is provided in the groove of the guide rail, which is used to allow the sliding piece 62 located in the groove to smoothly slide across the connection gap 61 between the front guide rail 11 and the rear guide rail 35.

[0051] 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.

[0052] The first door 1, located at the top of the vehicle body 3, significantly increases the space of the opening 512 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 even 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.

[0053] A transition piece 5 is provided inside the guide rail. The transition piece 5 provides support when the sliding piece 62 passes through the mating gap 61 between the front guide rail 11 and the rear guide rail 35, so that the sliding piece 62 can slide smoothly, thereby allowing the second door 2 to slide smoothly and smoothly in the entire guide rail. This avoids the second door 2 from getting stuck when it slides through the mating gap 61, and improves the feel and smoothness of opening and closing the door.

[0054] 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.

[0055] 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.

[0056] 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.

[0057] In one exemplary embodiment, such as Figures 9 to 12As shown, the transition piece 5 is slidably installed in the groove of the rear guide rail 35; the transition piece 5 slides in the rear guide rail 35 along with the sliding piece 62; the transition piece 5 can partially extend into the front guide rail 11 to cover the mating gap 61 between the front guide rail 11 and the rear guide rail 35, so that the sliding piece 62 slides smoothly in the front guide rail 11 and the rear guide rail 35.

[0058] The transition piece 5 is installed inside the rear guide rail 35 and slides within the groove of the rear guide rail 35. When the sliding piece 62 slides within the groove of the rear guide rail 35, the transition piece 5 can slide together with the sliding piece 62. That is, the transition piece 5 can be sleeved outside the sliding piece 62 and slides with the sliding piece 62 within the rear guide rail 35. The transition piece 5 is located between the sliding piece 62 and the groove of the rear guide rail 35. When the transition piece 5 slides towards the front guide rail 11, the transition piece 5 can partially extend into the groove of the front guide rail 11, allowing the sliding piece 62 to directly enter the front guide rail 11 through the transition piece 5. The sliding piece 62 does not need to pass through the mating gap 61 between the front guide rail 11 and the rear guide rail 35, avoiding jamming of the sliding piece 62 at the mating gap 61. The smooth connection between the transition piece 5 and the groove of the front guide rail 11 ensures smooth and stable overall sliding of the sliding piece 62, reducing the requirements for the mating accuracy of the front guide rail 11 and the rear guide rail 35.

[0059] It should be understood that the transition piece 5 can also be installed in the groove of the front guide rail 11 and slide in the front guide rail 11 with the sliding piece 62, partially extending into the rear guide rail 35 to cover the mating gap 61 between the front guide rail 11 and the rear guide rail 35.

[0060] In one exemplary embodiment, such as Figure 10 and Figure 13 As shown, the transition member 5 includes a receiving section 51 and an extension section 52. When the transition member 5 slides with the sliding member 62, the sliding member 62 is located in the cavity 511 formed by the receiving section 51. The extension section 52 is configured as two, with the first end of each extending towards the front guide rail 11 and the second end of each connecting to the receiving section 51. The channel 521 formed by the two extension sections 52 arranged side by side communicates with the cavity 511 of the receiving section 51. The sliding member 62 enters the front guide rail 11 from the cavity 511 through the channel 521.

[0061] When the slider 62 slides together with the transition member 5, the slider 62 is located in the cavity 511 formed by the receiving section 51.

[0062] When the slider 62 enters the front guide rail 11 from the rear guide rail 35, the slider 62 located in the cavity 511 enters the front guide rail 11 through the channel 521. That is, the slider 62 does not contact the mating gap 61 during the sliding process and will not get stuck when it slides past the mating gap 61.

[0063] When the slider 62 enters the rear guide rail 35 from the front guide rail 11, the slider 62 located in the groove of the front guide rail 11 enters the cavity 511 through the channel 521, and then slides together with the transition piece 5 in the rear guide rail 35.

[0064] In one exemplary embodiment, such as Figure 10 As shown, the opening 512 of the cavity 511, which communicates with the channel 521, is smaller than the size of the slider 62, so that the slider 62 drives the transition piece 5 to slide towards the front guide rail 11; the slider 62 can abut against the side wall of the receiving section 51 away from the opening 512, so that the slider 62 drives the transition piece 5 to slide in a direction away from the front guide rail 11. Figure 10 In the diagram, for clarity, the slider 62 is shown as a dashed line, and... Figure 10 The extreme position of one side of the transition piece 5 is also shown in the form of a dashed line.

[0065] When sliding within the rear guide rail 35, the slider 62 can drive the transition member 5 to slide in both directions. That is, the slider 62 abuts against the opening 512 of the receiving section 51 to drive the transition member 5 to slide forward on the guide rail 11, or the slider 62 abuts against one side wall of the receiving section 51 to drive the transition member 5 to slide in the opposite direction.

[0066] When the slider 62 slides towards the front guide rail 11, the transition piece 5 slides together with it by ensuring that the size of the slider 62 is larger than the size of the opening 512 of the cavity 511. This facilitates the slider 62's disengagement from the transition piece 5 and entry into the front guide rail 11. In practical applications, the size of the slider 62 can be set to be slightly larger than the size of the opening 512 of the cavity 511. This ensures that the slider 62 can properly drive the transition piece 5 to slide while also facilitating the disengagement of the slider 62 from the transition piece 5 and its entry into the front guide rail 11.

[0067] In one exemplary embodiment, such as Figure 10 As shown, a first limiting protrusion 351 is provided on the inner wall of the groove of the rear guide rail 35, and a recessed area 53 is formed at the connection between the extension section 52 and the receiving section 51; when the transition piece 5 slides to the limit position close to the front guide rail 11, the first limiting protrusion 351 is engaged in the recessed area 53 to restrict the bidirectional movement of the transition piece 5.

[0068] When the transition piece 5 slides to its limit position near the front guide rail 11, it is stopped and no longer slides towards the front guide rail 11. The slider 62 then disengages from the transition piece 5 and slides into the front guide rail 11. After the slider 62 enters the front guide rail 11, the transition piece 5 remains at its limit position near the front guide rail 11, awaiting the subsequent sliding of the slider 62 towards the rear guide rail 35. In other words, after the slider 62 enters the front guide rail 11, the transition piece 5 will not slide alone in the rear guide rail 35. When the slider 62 moves from the front guide rail 11 into the rear guide rail 35, it enters the cavity 511 through the channel 521 from the groove of the front guide rail 11. The slider 62 and the transition piece 5 slide together in the groove of the rear guide rail 35.

[0069] When the second door 2 slides, the sliding member 62 on the second door 2 is subjected to a large force. When the transition member 5 is limited, the sliding member 62 can be disengaged from the transition member 5, or the sliding member 62 can enter the cavity 511 through the channel 521.

[0070] In addition to the aforementioned limiting function, the first limiting protrusion 351 also supports the extension section 52: before the transition member 5 slides to the limit position close to the front guide rail 11, the first limiting protrusion 351 supports the extension section 52, so that the end of the extension section 52 will not abut against the inner wall of the front guide rail 11, thereby preventing the end of the extension section 52 from getting stuck at the docking gap 61 when the transition member 5 slides further toward the front guide rail 11, ensuring that the extension section 52 can smoothly cover the docking gap 61, and allowing the sliding member 62 to pass smoothly through the docking gap 61 position.

[0071] It should be understood that, in order to ensure that the transition piece 5 is reliably limited at the extreme position near the front guide rail 11, in addition to the limiting of the first limiting protrusion 351 and the recessed area 53, other limiting methods can also be used for fixing, such as the second limiting protrusion 54 and the guide groove 352.

[0072] In one exemplary embodiment, when the transition member 5 slides to its limit position near the front guide rail 11, the first end of the extension section 52 abuts against the inner wall of the groove of the rear guide rail 35, i.e. Figure 10 As shown by the dashed line.

[0073] When the transition piece 5 slides to the limit position near the front guide rail 11, that is, the slider 62 will enter the front guide rail 11 from the transition piece 5. The first end of the extension section 52 on the transition piece 5 abuts against the inner wall of the groove of the rear guide rail 35, so that the extension section 52 and the inner wall of the groove of the rear guide rail 35 are smoothly connected. Thus, the slider 62 will not get stuck when it enters the groove of the front guide rail 11 from the channel 521, and the slider 62 slides smoothly and steadily.

[0074] In one exemplary embodiment, such as Figure 9As shown, a guide groove 352 is provided on the wall of the rear guide rail 35, and a second limiting protrusion 54 is provided on the transition member 5. The second limiting protrusion 54 is located in the guide groove 352, so that the transition member 5 slides along the length direction of the rear guide rail 35 with the sliding member 62.

[0075] The second limiting protrusion 54 slides in the guide groove 352, which can serve as a guide on the one hand and a limiting function for the transition piece 5 on the other hand, so that the transition piece 5 can slide within the length range of the guide groove 352.

[0076] At the extreme position on one side of the transition piece 5 near the front guide rail 11, there are two limiting structures: "first limiting protrusion 351 and recessed area 53" and "second limiting protrusion 54 and guide groove 352" to ensure the reliability of the limiting. At the same time, the limiting structure of "first limiting protrusion 351 and recessed area 53" can play a bidirectional limiting role when the transition piece 5 is not subjected to external force.

[0077] In one exemplary embodiment, such as Figure 6 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.

[0078] 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.

[0079] 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.

[0080] 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.

[0081] In one exemplary embodiment, such as Figure 10As shown, 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. The U-shaped opening 512 of the guide block 111 is connected to the first U-shaped groove. A second U-shaped groove is provided on the rear guide rail 35. After the rear guide rail 35 is connected to the guide block 111, the second U-shaped groove is connected to the U-shaped opening 512 of the guide block 111. A mating gap 61 is formed between the first U-shaped groove and the second U-shaped groove.

[0082] 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.

[0083] 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.

[0084] 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 is provided with a slider 62 for sliding in the complete track formed by the first U-shaped groove and the second U-shaped groove.

[0085] One end of the upper hinge assembly 21 (i.e., the sliding member 62) 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.

[0086] 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.

[0087] 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.

[0088] 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 body 2 can slide along each guide rail. Finally, the second door body 2 is embedded in the opening 512 position on the vehicle body 3 to close the door smoothly.

[0089] 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.

[0090] This application also provides a vehicle, which includes a body 3 and the aforementioned door assembly; as Figures 1 to 3 As shown, the vehicle body 3 is provided with a first installation area 31 and a second installation area 32 that are connected. 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.

[0091] The first installation area 31 and the second installation area 32 form a complete opening 512 on 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.

[0092] In one exemplary embodiment, such as Figure 1 and Figure 3 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.

[0093] 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.

[0094] 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.

[0095] 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.

[0096] Example 2

[0097] The embodiments of this application mainly describe the door assembly and some other related structures of the vehicle.

[0098] 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 the opening 512 facing downwards, 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.

[0099] 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.

[0100] Both the front guide rail 11 and the rear guide rail 35 are U-shaped pieces with openings 512 facing downwards. The sliding mechanism on the door (such as the upper hinge assembly 21) is slidably installed in the openings 512 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 openings 512 facing downwards. 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.

[0101] In one exemplary embodiment, such as Figures 6 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.

[0102] 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.

[0103] 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.

[0104] 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.

[0105] 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.

[0106] 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.

[0107] 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 512.

[0108] 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.

[0109] 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.

[0110] 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.

[0111] 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 512 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.

[0112] 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 512 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 512 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 512 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 512 of the guide block 111.

[0113] 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 512 of the guide block 111, such as setting the front end of the rear guide rail 35 to a smooth surface.

The telescopic strut 142 drives the first door 1 to rotate around the rotating hinge 141.

[0115] 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.

[0116] 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.

[0117] The first door body 1 includes a door sheet metal 12 and a light-transmitting component 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 component 13 respectively, and the door sheet metal 12 on both sides of the light-transmitting component 13 blocks the telescopic support rods 142.

[0118] In an exemplary embodiment, there are two first mounting areas 31 and two second mounting areas 32 on the vehicle; 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.

[0119] 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.

[0120] In one exemplary embodiment, 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 mounting area 31 and the second mounting area 32, and docks with the front guide rail 11 when the first door 1 is closed to form a complete track for the sliding of the second door 2.

[0121] 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.
