Description

Technical Field

[0001] This application relates to, but is not limited to, door sealing technology, and in particular to a door assembly sealing structure 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 many problems at the contact point between the gull-wing doors and revolving doors that affect vehicle performance. For example, the sealing at the connection point between the two types of doors is poor, resulting in air leakage and incomplete sealing. Summary of the Invention

[0004] This application provides a door assembly sealing structure and a vehicle, which ensures that the door assembly remains tightly sealed after the structural form is changed, and does not affect the normal opening and closing of the door.

[0008] Furthermore, the door assembly sealing structure also includes an upper hinge assembly, which is installed at the upper end of the second door body for sliding engagement with the guide rail;

[0009] The sealing element includes a first sealing strip and a second sealing strip, which are respectively disposed on both sides of the upper hinge assembly to seal the gap between the first door body and the second door body.

[0010] Furthermore, the first sealing strip is installed on the second door body and is located on the side of the upper hinge assembly closer to the outside of the vehicle;

[0011] The second sealing strip is mounted on the front guide rail and is located on the side of the upper hinge assembly closer to the vehicle interior.

[0012] Furthermore, a first decorative element is provided on the first door body, a second decorative element is provided on the second door body, and a first sealing strip is provided between the first decorative element and the second decorative element;

[0013] At least one of the first decorative element and the second decorative element obscures the first sealing strip.

[0014] Furthermore, the front guide rail includes an upper guide rail box, a guide rail body, and a lower guide rail box. The upper guide rail box and the lower guide rail box form a cavity. The guide rail body is located in the cavity. One end of the upper hinge assembly extends into the cavity and slides with the guide rail body.

[0015] The second sealing strip is installed on the lower part of the guide rail box.

[0016] Furthermore, the second door body includes a door sheet metal and a second decorative piece disposed on the outer surface of the door sheet metal, the first sealing strip is installed on the door sheet metal, and the second sealing strip abuts against the door sheet metal;

[0017] The second decorative element covers the first sealing strip.

[0018] Furthermore, the first sealing strip includes a first mounting portion, a first airbag, and a lip. The first mounting portion is used to install on the second door body. The first airbag and the lip are both disposed on the first mounting portion, and the lip is located on the side of the first airbag closer to the outside of the vehicle.

[0019] Furthermore, the end of the first decorative piece is bent toward the inward direction of the vehicle to form an abutment end, the abutment end including a first plane and a second plane, the second plane being connected to the end of the first plane, and the first plane and the second plane being perpendicular;

[0020] The lip edge abuts against the first plane, and the first airbag abuts against the second plane.

[0021] Furthermore, the free end of the lip extends outward in the direction of the vehicle to abut against the first plane.

[0022] Furthermore, the second sealing strip includes a second mounting portion, a second airbag, and a third airbag. The second mounting portion is used to be mounted on the front guide rail, the second airbag is mounted on the second mounting portion, and the third airbag is disposed on the side of the second airbag opposite to the second mounting portion.

Detailed Implementation

[0047] 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.

[0048] Example 1

[0049] This application provides a door assembly sealing structure, such as Figures 1 to 12 As shown, the door assembly sealing structure includes a first door body 1, a second door body 2, a guide rail, and a seal. 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 abuts against the front guide rail 11 to form a complete track for the sliding of the second door body 2. A seal is disposed between the first door body 1 and the second door body 2.

[0050] 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.

[0051] 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.

[0052] 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.

[0053] 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.

[0054] 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.

[0055] A seal is provided between the first door body 1 and the second door body 2 to improve the overall sealing performance of the door assembly and avoid reducing the sealing performance of the door assembly after setting the door assembly to include two door bodies.

[0056] In one exemplary embodiment, such as Figure 5 , Figure 9 and Figure 10As shown, the door assembly sealing structure also includes an upper hinge assembly 21, which is installed on the upper end of the second door body 2 for sliding cooperation with the guide rail; the sealing element includes a first sealing strip 5 and a second sealing strip 6, which are respectively disposed on both sides of the upper hinge assembly 21 to seal the gap between the first door body 1 and the second door body 2.

[0057] 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.

[0058] The sealing element includes a first sealing strip 5 and a second sealing strip 6, which are respectively disposed on the inner and outer sides of the upper hinge assembly 21. The first sealing strip 5 and the second sealing strip 6 seal the gap between the first door body 1 and the second door body 2. In other words, one of the first sealing strip 5 and the second sealing strip 6 is located on the outer side of the upper hinge assembly 21 to prevent dust and other external objects from entering the upper hinge assembly 21; the other is located on the inner side of the upper hinge assembly 21 to further seal the gap and prevent some dust and other objects from entering the upper hinge assembly 21 from entering the vehicle interior, thereby ensuring the cleanliness of the vehicle interior and the sealing and sound insulation performance of the entire vehicle.

[0059] The first sealing strip 5 and the second sealing strip 6 can be long strip-shaped components extending along the length of the vehicle body 3, so as to match the gap between the first door body 1 and the second door body 2.

[0060] It should be understood that the specific number and location of the seals can be adjusted according to the actual situation. For example, the seals may include four sealing strips, with two on each side of the upper hinge assembly 21. This application does not limit this.

[0061] In one exemplary embodiment, such as Figure 10 As shown, the first sealing strip 5 is installed on the second door body 2 and is located on the side of the upper hinge assembly 21 closer to the outside of the vehicle; the second sealing strip 6 is installed on the front guide rail 11 and is located on the side of the upper hinge assembly 21 closer to the inside of the vehicle.

[0062] The first sealing strip 5 and the second sealing strip 6 are respectively disposed on the inner and outer sides of the upper hinge assembly 21. Specifically, the first sealing strip 5 is located on the side of the upper hinge assembly 21 closer to the outside of the vehicle, and the second sealing strip 6 is located on the side of the upper hinge assembly 21 closer to the inside of the vehicle. The first sealing strip 5 plays a preliminary and primary sealing role, while the second sealing strip 6 plays a supplementary sealing role.

[0063] The first sealing strip 5 is installed on the second door body 2, and the second sealing strip 6 is installed on the front guide rail 11. The first sealing strip 5 is located on the outer side of the second door body 2, while the second sealing strip 6 is located close to the interior of the vehicle and on the front guide rail 11. The arrangement is reasonable and facilitates the installation of the first sealing strip 5 and the second sealing strip 6.

[0064] It should be understood that the installation positions of the first sealing strip 5 and the second sealing strip 6 can also be adjusted according to the actual situation, such as installing the first sealing strip 5 on the front guide rail 11, or installing the second sealing strip 6 on the second door body 2. This application does not limit this.

[0065] In one exemplary embodiment, such as Figure 10 As shown, a first decorative element 7 is provided on the first door body 1, and a second decorative element 8 is provided on the second door body 2. A first sealing strip 5 is provided between the first decorative element 7 and the second decorative element 8; at least one of the first decorative element 7 and the second decorative element 8 covers the first sealing strip 5.

[0066] The first decorative element 7 and the second decorative element 8 are respectively located on the outer surfaces of the first door body 1 and the second door body 2 to serve a decorative purpose. The ends of the first decorative element 7 and the second decorative element 8 protrude from the first door body 1 and the second door body 2 to achieve a better decorative effect and prevent the edges of the first door body 1 or the second door body 2 from being exposed.

[0067] The first decorative element 7 or the second decorative element 8 covers the first sealing strip 5 to prevent the first sealing strip 5 from being exposed, thereby improving the overall aesthetics of the vehicle and improving the vehicle's sealing performance without affecting its appearance.

[0068] In one exemplary embodiment, such as Figure 10 As shown, the front guide rail 11 includes an upper guide rail box 121, a guide rail body 122, and a lower guide rail box 123. The upper guide rail box 121 and the lower guide rail box 123 form a cavity. The guide rail body 122 is located in the cavity. One end of the upper hinge assembly 21 extends into the cavity and slides in cooperation with the guide rail body 122. The second sealing strip 6 is installed on the lower guide rail box 123.

[0069] The upper part 121 of the guide rail box is located above the lower part 123 of the guide rail box. The two are fastened together to form a cavity structure. The guide rail body 122 is located in the cavity. The upper hinge assembly 21 is provided with a pulley at one end, which extends into the cavity to facilitate the sliding engagement of the guide rail body 122.

[0070] The second sealing strip 6 is installed on the edge of the lower part 123 of the guide rail box to facilitate the installation of the second sealing strip 6.

[0071] In one exemplary embodiment, such as Figure 10As shown, the second door 2 includes a door sheet metal 24 and a second decorative piece 8 disposed on the outer surface of the door sheet metal 24. The first sealing strip 5 is installed on the door sheet metal 24, and the second sealing strip 6 abuts against the door sheet metal 24; the second decorative piece 8 covers the first sealing strip 5.

[0072] The first sealing strip 5 is installed at the upper edge of the door sheet metal 24 for easy installation. The second sealing strip 6 is installed at the edge of the lower part 123 of the guide rail box and abuts against the door sheet metal 24 for sealing.

[0073] The second decorative element 8 covers the first sealing strip 5 to prevent the first sealing strip 5 from being exposed.

[0074] In one exemplary embodiment, such as Figure 11 As shown, the first sealing strip 5 includes a first mounting part 51, a first airbag 52, and a lip 53. The first mounting part 51 is used to install on the second door body 2. The first airbag 52 and the lip 53 are both disposed on the first mounting part 51, and the lip 53 is located on the side of the first airbag 52 closer to the outside of the vehicle.

[0075] The first mounting part 51 can be a U-shaped slot to facilitate installation at the upper edge of the door sheet metal 24. The first airbag 52 can be a cylindrical structure with an approximately circular cross-section and a hollow center to improve elasticity, sealing effect, sound absorption, etc., and reduce manufacturing costs. The lip 53 is located on the outside of the first airbag 52; in other words, the lip 53 is relatively closer to the outside of the vehicle, and the first airbag 52 is relatively closer to the inside of the vehicle. The lip 53 plays a preliminary sealing and interception role to prevent large particles of impurities from entering the vehicle interior; the first airbag 52 provides better sealing and sound insulation effects.

[0076] It should be understood that the specific structure of the first sealing strip 5 can be further modified, such as: multiple airbags can be set along the thickness direction of the vehicle body 3 to further improve the sealing effect; multiple lips 53 can be set or changed to other forms; this application does not limit this.

[0077] In one exemplary embodiment, such as Figure 10 and Figure 11 As shown, the end of the first decorative piece 7 is bent towards the inside of the vehicle to form an abutment end 71. The abutment end 71 includes a first plane 711 and a second plane 712. The second plane 712 is connected to the end of the first plane 711, and the first plane 711 and the second plane 712 are perpendicular. The lip 53 abuts against the first plane 711, and the first airbag 52 abuts against the second plane 712.

[0078] The end of the first decorative piece 7 is bent inwards towards the vehicle to form an abutment end 71, preventing the abutment end 71 from protruding from the outer surface of the first decorative piece 7 and keeping the outer surface of the vehicle body 3 flat. The abutment end 71 can be in the form of a right-angle bend; in other words, the abutment end 71 includes a first plane 711 and a second plane 712 that are perpendicularly connected. The lip 53 and the first airbag 52 abut against the first plane 711 and the second plane 712 respectively, improving the sealing effect.

[0079] In one exemplary embodiment, such as Figure 10 and Figure 11 As shown, the free end of the lip 53 extends outward in the direction of the vehicle to abut against the first plane 711.

[0080] The lip 53 extends outward to better block impurities and prevent dust and other impurities from accumulating at the free end of the lip 53 and entering the vehicle interior.

[0081] It should be understood that when the connection method and relative position relationship between the first door body 1 and the second door body 2 change, the extension method of the lip 53 can also be modified. For example, the free end of the lip 53 can extend in the direction outside the vehicle, or the lip 53 can be perpendicular to the first plane 711.

[0082] In one exemplary embodiment, such as Figure 12 As shown, the second sealing strip 6 includes a second mounting part 61, a second airbag 62 and a third airbag 63. The second mounting part 61 is used to be mounted on the front guide rail 11. The second airbag 62 is mounted on the second mounting part 61. The third airbag 63 is disposed on the side of the second airbag 62 away from the second mounting part 61. The third airbag 63 abuts against the second door body 2.

[0083] The second mounting part 61 can be a U-shaped slot to facilitate installation at the edge of the lower part 123 of the guide rail box. The second airbag 62 can be a cylindrical structure with an approximately circular cross-section, and the middle position is set to improve elasticity, sealing effect, sound absorption effect, etc., and reduce manufacturing cost. The structure of the third airbag 63 can be the same as that of the second airbag 62.

[0084] The third airbag 63 is located on the side of the second airbag 62 away from the second mounting part 61, which makes the sealing part of the second sealing strip 6 longer and can seal larger gaps. At the same time, it avoids the problem of poor sealing effect caused by setting the size of the individual airbag to be large.

[0085] It should be understood that the specific structure of the second sealing strip 6 can be adjusted according to the actual situation. For example, a lip or other structure can be added to the second mounting part 61, or the second airbag 62 can be set as a solid structure. This application does not limit this.

[0086] This application embodiment also provides a vehicle, the vehicle including a body 3 and the aforementioned door assembly sealing structure; 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.

[0087] 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.

[0088] 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.

[0089] 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.

[0090] 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.

[0091] Example 2

[0092] This application mainly describes some other related structures of the door assembly sealing structure:

[0093] In an exemplary embodiment, 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.

[0094] When the front guide rail 11 and the rear guide rail 35 are docked, a guide block 111 is provided at the rear end of the front guide rail 11 to facilitate successful docking and improve connection stability. 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 docking the rear guide rail 35 with the front guide rail 11 to form a complete guide rail, facilitating the sliding of the second door 2. 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 to facilitate the entry of the rear guide rail 35 and prevent significant swaying after the rear guide rail 35 enters the limiting groove 112. The guide block 111 effectively improves the docking accuracy of the front guide rail 11 and the rear guide rail 35, avoiding deviations after docking that could cause the second door 2 to slide poorly, thus ensuring smooth opening and closing of the door.

[0095] 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.

[0096] 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 misalignment and ensuring proper mating. The rotatable nature of the rear guide rail 35 allows it to automatically adjust its position during mating to enter the limiting groove 112 of the guide block 111, making the process simple and reliable. 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 (e.g., the upper hinge assembly 21) can be 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 part with the opening facing downward. 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 connect with the rear guide rail 35.

[0097] 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.

[0098] 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 to restrict the rotation angle of the rear guide rail 35, allowing the rear guide rail 35 to rotate within a certain angle range, preventing it from deviating from its intended connection with the guide block 111 due to excessive rotation. A welding point can be provided at one end of the fixed bracket 4 for spot welding to securely connect it to the vehicle body 3.

[0099] 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.

[0100] 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 install, eliminating the need for additional components as the limiting part 43, thus simplifying the structure of the fixed bracket 4 and improving the overall reliability of the door assembly. A gap 45 is provided between the baffle and the rear guide rail 35. When the rear guide rail 35 rotates and abuts against the baffle, it is limited, ensuring that the rear guide rail 35 can only rotate within a certain range and will not exceed it. In practical applications, the size of the gap 45 can be adjusted to regulate the rotational range of the rear guide rail 35. The fixed bracket 4 and the top of the U-shaped rear guide rail 35 are connected by a connecting shaft, allowing the rear guide rail 35 to rotate horizontally relative to the fixed bracket 4 within a certain range. The connecting shaft at the top of the rear guide rail 35 does not affect the sliding mechanism located within the U-shaped opening.

[0101] 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.

[0102] 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.

[0103] 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.

[0104] 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.

[0105] After the first U-shaped groove and the second U-shaped groove are connected, a complete sliding groove for the sliding mechanism is formed. The front guide rail 11 and the rear guide rail 35 are connected to form a complete guide rail. By adopting the form of the 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, so that the second door body 2 can slide along the X-direction (length direction of the vehicle body 3) to realize the opening or closing of the door.

[0106] In an exemplary embodiment, the door assembly may further 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.

[0107] 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.

[0108] 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.

[0109] 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.

[0110] 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.

[0111] 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.

[0112] 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.

[0113] 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.

[0114] 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.

[0115] 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.

[0116] 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.

[0117] 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.

[0118] 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.

[0119] When opening and closing the car door: when the door is fully closed, the upper hinge assembly 21 is located in the front guide rail 11 of the first door body 1; when the door is to be opened, the second door body 2 slides open first, and then the first door body 1 rotates open, and the upper hinge assembly 21 slides with the second door body 2, entering the rear guide rail 35 from the front guide rail 11 to facilitate the opening of the first door body 1; when the door is to be closed, the first door body 1 rotates close first, and then the second door body 2 slides close, and the upper hinge assembly 21 slides with the second door body 2, entering the front guide rail 11 from the rear guide rail 35.

[0120] In one exemplary embodiment, such as Figure 1 As shown, a lock assembly 36 is provided on the vehicle body 3. The lock assembly 36 is located at the edge of the first installation area 31. The lock assembly 36 is configured to limit the first door 1 after the first door 1 is closed.

[0121] After the first door 1 is closed, the lock assembly 36 limits the opening of the first door 1 to prevent it from being opened accidentally. Furthermore, when the first door 1 is rotated to close, the lock assembly 36 also limits its rotation to prevent it from being over-rotated.
