Door assembly and vehicle

Abstract

This application provides a door assembly and a vehicle. The door assembly includes a door panel and an opening assembly. The door panel is operable to close or open the door opening. The opening assembly includes a drive arm, a driven arm, and a drive motor. The opposite ends of the drive arm and the driven arm are pivotally connected to the vehicle body and the door panel, respectively, thereby driving the drive arm and the driven arm to rotate the door panel to open or close the door opening. One end of a stabilizer arm is pivotally connected to the vehicle body, and the other end of the stabilizer arm is movably connected to the door panel. The plane on which the drive arm and the driven arm are located is a first plane. The projection of the stabilizer arm along a direction perpendicular to the first plane always falls on the first plane or an extension of the first plane. This further ensures that when the door panel rotates, it does not rotate unnecessarily under the combined action of the stabilizer arm, the drive arm, and the driven arm, preventing the door panel from misaligning with the door opening when opening or closing, thus affecting the overall usability of the door assembly.

Description

Technical Field

[0001] This application relates to the field of vehicle structures, and in particular to a door assembly and a vehicle. Background Technology

[0002] As the automotive market develops, the demands for vehicle comfort, convenience, and safety are becoming increasingly stringent. With the wider use of family cars, the requirements for vehicle carrying capacity are also becoming more extensive, often requiring the carrying of passengers with mobility impairments, wheelchair users, and large pieces of luggage.

[0003] However, in practical applications, the first end of a car door is pivotally connected to the vehicle body, while the opposite second end rotates relative to the first end when the door is opened or closed. When the door is opened, it rotates away from the vehicle body to a side-opening configuration. In this case, the door occupies a large amount of space, and the size of the door opening is also limited, making it difficult to bear loads under these conditions. Summary of the Invention

[0004] This application provides a door assembly that occupies less space when the door panel is opened, thereby maximizing the utilization of the door opening space.

[0005] To address the aforementioned technical problems, this application proposes a vehicle door assembly, installed on a vehicle body. The vehicle body has a door opening, and the door assembly includes a door panel operable to close or open the door opening. An opening assembly includes a drive arm, a driven arm, and a drive motor. The drive arm and the driven arm are pivotally connected at opposite ends to the vehicle body and the door panel, respectively. The drive motor is connected to the drive arm and drives it to rotate. A stabilizing arm is pivotally connected at one end to the vehicle body, and movably connected at the other end to the door panel. The plane containing the drive arm and the driven arm is a first plane, and the projection of the stabilizing arm along a direction perpendicular to the first plane always falls on the first plane or an extension of the first plane.

[0006] Specifically, the line connecting the center of gravity of the stabilizing arm, the center of gravity of the driving arm, and the center of gravity of the driven arm forms a triangle.

[0007] Specifically, the driven arm includes a first arm and a second arm that are telescopically connected to each other. The end of the first arm away from the second arm is pivotally connected to the vehicle body, and the end of the second arm away from the first arm is pivotally connected to the door panel.

[0008] Specifically, the driven arm includes a first arm and a second arm that are pivotally connected. The end of the first arm away from the second arm is pivotally connected to the vehicle body, and the end of the second arm away from the first arm is pivotally connected to the door panel.

[0009] Specifically, the door opening assembly further includes an electric support rod, which is fixed to the vehicle body. The electric support rod includes a telescopic support section, which is fixedly connected to the door panel. The electric support rod assists the drive motor in driving the door panel away from the vehicle body.

[0010] Specifically, the stabilizer arm is provided with a guide rail groove, and the door panel is provided with a protrusion. The protrusion is installed in the guide rail groove and can slide along the guide rail groove. During the process of the drive motor driving the drive arm to rotate, the electric strut first drives the strut part to retract to a preset position, and then the electric strut drives the strut part to extend, causing the door panel to rotate relative to the vehicle body first, and then move along the length direction of the vehicle body to open the door opening. The protrusion moves away from the vehicle body and then moves closer to the vehicle body within the guide rail groove.

[0011] Specifically, the stabilizer arm includes a first support arm and a second support arm. The first support arm connects the vehicle body and the second support arm, and the second support arm connects the door panel. The included angle between the first support arm and the second support arm is greater than or equal to 120 degrees and less than 180 degrees.

[0012] Specifically, the other end of the stabilizer arm is also pivotally connected to the door panel. During the rotation of the drive arm driven by the drive motor, the drive arm drives the driven arm to rotate synchronously, and the stabilizer arm rotates synchronously with the door panel.

[0013] Specifically, it also includes a door controller, which is electrically connected to the drive motor and controls the opening or stopping of the drive motor.

[0014] Specifically, it also includes a sensor electrically connected to the door controller. When the sensor detects an obstacle to opening the door, it sends a feedback signal to the door controller, which then controls the operation of the door panel based on the feedback signal.

[0015] Specifically, the sensor is an ultrasonic radar or a displacement sensor.

[0016] Specifically, the alarm is connected to the door controller, and the door controller controls the alarm to issue an alert based on the sensing signal from the sensor.

[0017] Another aspect of this application provides a vehicle, including a body, the body having at least a first door opening and a second door opening, the first door opening and the second door opening being arranged adjacent to each other. A door assembly is mounted on the body, and the door assembly includes at least a first door assembly and a second door assembly, wherein the first door assembly opens or closes the first door opening, and the second door assembly opens or closes the second door opening. The first door assembly includes a first door panel, and the second door assembly includes a second door panel. When the first door panel and the second door panel do not interfere with each other, the first door assembly and the second door assembly are door assemblies as described in any of the preceding claims. When the end of the first door panel facing the second door panel overlaps with the outer wall of the second door panel facing the exterior of the vehicle, the first door assembly is a door assembly as described in any of the preceding claims, and the second door assembly is a door assembly as described in the preceding portions.

[0018] The beneficial effects of this application are as follows: Compared to existing door assemblies, the door assembly proposed in this application is installed on the vehicle body, with a door opening on the vehicle body. The door assembly includes a door panel and an opening assembly, and the door panel can be operated to close or open the door opening. The opening assembly includes a drive arm, a driven arm, and a drive motor. The opposite ends of the drive arm and the driven arm are pivotally connected to the vehicle body and the door panel, respectively. The drive motor is connected to the drive arm and drives the drive arm to rotate, thereby causing the drive arm and the driven arm to jointly drive the door panel to rotate to open or close the door opening. Compared to existing side-opening door structures, when the door panel of this application is opened, the drive motor connected to the drive arm rotates, causing the door panel to be misaligned with the vehicle body, and causing the entire door panel to move relative to the vehicle body along the length of the vehicle body to fully open the door opening. Therefore, when the door assembly of this application is opened, since the door panel moves along the length of the vehicle body after being misaligned with the vehicle body, only the space required for the door panel to be misaligned with the vehicle body is needed to achieve the spatial conditions for opening the door opening. Therefore, the door panel can be opened with minimal lateral space occupied by the vehicle. Furthermore, the door panel moves along the body until there is no obstruction between it and the door opening, allowing the door to be fully opened. This effectively increases the usable area of ​​the door opening when the door panel is open, further facilitating passenger entry and exit. The door assembly also includes a stabilizer arm, one end of which is pivotally connected to the body, and the other end is movably connected to the door panel, ensuring stable rotation of the entire door panel when it is open. The plane containing the drive arm and driven arm is the first plane. The projection of the stabilizer arm perpendicular to the first plane always falls on the first plane or its extension. Furthermore, the combined action of the stabilizer arm, drive arm, and driven arm prevents unnecessary rotation that could cause misalignment between the door panel and the door opening when opening or closing, thus affecting the overall usability of the door assembly.

[0029] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0030] In the description of the embodiments of this application, it should be noted that, unless otherwise explicitly specified and limited, the terms "connected" and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in the embodiments of this application based on the specific circumstances.

[0031] One aspect of this application provides a vehicle, including a body 4 and a door assembly, please refer to the reference. Figure 1 and Figure 2 , Figure 1 This is a schematic diagram of the structure of one embodiment of the door assembly provided in this application; Figure 2 yes Figure 1The image shows a top view of the door assembly described herein. In some embodiments, the vehicle body 4 has at least a first door opening 41 and a second door opening 42, which are arranged adjacent to each other. The door assembly is mounted on the vehicle body 4 and includes at least a first door assembly and a second door assembly, wherein the first door assembly opens or closes the first door opening 41, and the second door assembly opens or closes the second door opening 42. The first door assembly includes a first door panel 43, and the second door assembly includes a second door panel 44. The first door assembly and the second door assembly of the vehicle may use the same door assembly or slightly different door assemblies depending on the actual design or requirements. The structure of the first door assembly and the second door assembly will be described in detail below for different vehicle design scenarios:

[0032] [First Design Scenario]

[0033] In this first design configuration, the first door panel 43 and the second door panel 44 do not interfere with each other. That is, the edges of the first door panel 43 and the second door panel 44 are spaced apart, and their edges do not overlap. In this case, the first door assembly and the second door assembly can use the same door assembly.

[0034] Example 1:

[0035] In Embodiment 1, both the first and second door assemblies include a door panel 1 and an opening assembly 2. The door panel 1 can be operated to close or open the door opening 40. The opening assembly 2 includes a drive arm 21, a driven arm 22, and a drive motor 23. The opposite ends of the drive arm 21 and the driven arm 22 are pivotally connected to the vehicle body 4 and the door panel 1, respectively. The drive motor 23 is connected to the drive arm 21 and drives the drive arm 21 to rotate, thereby causing the drive arm 21 and the driven arm 22 to jointly rotate the door panel 1 to open or close the door opening 40. Compared with the existing side-opening door structure, the door panel 1 can be opened with less space on the side of the vehicle, and the effective area of ​​the door opening 40 when the door panel 1 is opened is effectively increased, further facilitating passengers to get in and out of the vehicle. The door assembly also includes a stabilizer arm 3. The first end of the stabilizer arm 3 is pivotally connected to the vehicle body 4, and the second end of the stabilizer arm 3, opposite to the first end, is movably connected to the door panel 1. This ensures that the entire door panel 1 can rotate relatively stably when it is opened, avoiding unnecessary resistance to the door panel 1 due to unstable forces at various points, which would affect the opening and closing of the door panel 1. The plane containing the drive arm 21 and the driven arm 22 is the first surface 20. The projection of the stabilizer arm 3 along a direction perpendicular to the first surface 20 always falls on the first surface 20 or its extension surface. This further ensures that when the door panel 1 rotates, it does not rotate unnecessarily under the combined action of the stabilizer arm 3, drive arm 21, and driven arm 22, preventing misalignment between the door panel 1 and the door opening 40 when opening or closing, thus affecting the overall usability of the door assembly.

[0036] When opening the door using this door assembly, compared to vehicles with traditional rotating side doors where one end of the door panel 1 is pivotally connected to the body 4 and the other end is latched to the body 4, opening the door panel 1 involves opening the latch and rotating the door panel 1 away from the body 4. In this case, the effective door opening 40 is only from the edge of the door panel 1 to the edge of the body 4, resulting in a smaller effective door opening 40. However, the door assembly proposed in this application utilizes a drive motor 23 to drive the drive arm 21 and the driven arm 22, causing the door panel 1 to be offset from the body 4, and moving the entire door panel 1 relative to the body 4 along the length of the body 4 until the door opening 40 is fully opened. Therefore, when opening the door panel 1, the door assembly of this application, because the door panel 1 moves along the length of the body 4 after being offset, only requires the space of the offset between the door panel 1 and the body 4 to achieve the spatial condition for opening the door opening 40. At this point, when opening the door panel 1, only a small space away from the vehicle body 4 is needed to fully open the door panel 1. Furthermore, the door panel 1 can be moved along the vehicle body 4 until there is no covered area between it and the door opening 40, meaning the door opening 40 can be fully opened. At this time, the distance between the edge of the door panel 1 and the edge of the vehicle body 4 increases, and the size of the opened door opening 40 is 2-2.5 times the size of the door opening that can be opened with a traditional structure. This greatly increases the comfort of passengers getting in and out of the vehicle, and allows larger items to be placed inside the vehicle when needed.

[0037] Furthermore, the line connecting the center of gravity of the stabilizer arm 3, the center of gravity of the drive arm 21, and the center of gravity of the driven arm 22 forms a triangle. With the help of the stability of the triangle, it is further ensured that the entire door panel 1 can rotate relatively smoothly under the drive of the door opening assembly 2. The door panel 1 will not rotate unnecessarily due to only part of the structure being subjected to the force of the drive arm 21 and the driven arm 22, which would affect the normal opening and closing of the door panel 1.

[0038] To ensure that the driven boom 22 can open the door panel 1 to the largest possible angle when rotating synchronously with the door panel 1, please refer to... Figure 3 , Figure 3 yes Figure 1The diagram shows a structural schematic of one embodiment of the door opening assembly described herein. Further, the driven arm 21 includes a first arm 221 and a second arm 222 pivotally connected. The end of the first arm 221 away from the second arm 222 is pivotally connected to the vehicle body 4, and the end of the second arm 222 away from the first arm 221 is pivotally connected to the door panel 1. By pivotally connecting the first arm 221 and the second arm 222, when the driven arm 22 pivots under the drive of the drive motor 23 and the drive arm 21, the angle that the driven arm 22 can rotate is limited. Therefore, the first arm 221 and the second arm 222 are additionally provided. When the angle that the driven arm 22 can rotate reaches its limit, the first arm 221 and the second arm 222 pivot, achieving a larger rotation angle. This ensures that when the door panel 1 is opened, it is as close as possible to the vehicle body 4, avoiding occupying a large space perpendicular to the vehicle body. This allows the door assembly to still open the door panel 1 even when the vehicle has limited side space.

[0039] As an alternative to the above, in some other embodiments, the driven arm 22 includes a first arm 221 and a second arm 222 that are telescopically connected to each other. The end of the first arm 221 away from the second arm 222 is pivotally connected to the vehicle body 4, and the end of the second arm 222 away from the first arm 221 is pivotally connected to the door panel 1. Similarly, since the angle that the driven arm 22 can rotate itself is limited, the first arm 221 and the second arm 222 are additionally provided. When the angle that the driven arm 22 can rotate itself reaches its limit, the first arm 221 and the second arm 222 extend and continue to open the door panel 1 under the drive of the drive motor 23 and the drive arm 21 until the door panel 1 reaches the preset position and the door is opened.

[0040] In order to minimize the amount of door opening 40 covered when the door panel 1 is opened, please further refer to... Figure 5 , Figure 5 yes Figure 1 The diagram shows the structure of the stabilizer arm described above. The stabilizer arm 3 includes a first support arm 31 and a second support arm 32. The first support arm 31 connects to the vehicle body 4 and the second support arm 32, while the second support arm 32 connects to the door panel 1. The included angle between the first support arm 31 and the second support arm 32 is greater than or equal to 120 degrees and less than 180 degrees. Figure 5 The included angle α in the range is 120°≤α<180°. Specifically, it can be 120°, 140°, 150°, 170°, 179°, etc., to ensure that when the door panel 1 opens the door opening 40, it can make a certain amount of clearance with the body 4, so that when the door panel 1 is opened, it can cover a small area of ​​the door opening 40, so that larger items can be placed through the door opening 40 when the door panel 1 is opened.

[0041] Understandably, specifically, the second end of the aforementioned stabilizer arm 3 can also be pivotally connected to the door panel 1. During the process of the drive motor 23 driving the drive arm 21 to rotate, the drive arm 21 drives the driven arm 22 to rotate synchronously, and the stabilizer arm 3 rotates synchronously with the door panel 1. This further ensures that the stabilizer arm 3 can play a certain supporting role throughout the entire process of the door panel 1 moving away from the door opening 40, and avoids unnecessary rotation of the door panel 1 caused by only the action of the drive arm 21 and the driven arm 22 during the opening or closing of the door panel 1, thereby affecting the opening and closing effect of the entire door assembly.

[0042] To achieve automatic door opening, please refer to... Figure 9 , Figure 9 This is a schematic diagram of the electrical control logic of the door assembly provided in this application. The door assembly also includes a door controller 9, which is electrically connected to the drive motor 23 and controls the opening and stopping of the drive motor 23. When the door controller 9 receives a signal from the instrument panel or a switch on the door panel 1, the door controller 9 controls the drive motor 23 to turn on, thereby driving the door opening assembly 2 to open or close the door panel 1, completing the work of the door assembly. Therefore, when it is necessary to open or close the door, as long as a signal to open or close the door is triggered to the door controller 9, such as a switch button, the door controller 9 can control the drive motor 23 to turn on, thereby driving the door opening assembly 2 to open or close the door panel 1.

[0043] Because the door opening assembly 2 of the vehicle in this application moves along the length of the vehicle body 4 when controlling the door panel 1 to open, that is, it moves forward or backward. For the occupants sitting inside the vehicle, there is a certain blind spot in the rear view or the window view. When there is an obstacle in the blind spot, the forward and backward movement of the door panel 1 is unsafe. In order to ensure the safety of opening or closing the door, the door assembly further includes a sensor 5, which is electrically connected to the door controller 9. When the sensor 5 detects an obstacle in the blind spot that affects the opening of the door, it sends a feedback signal to the door controller 9. The door controller 9 controls the operation of the door panel 1 according to the feedback signal. Specifically, when the sensor 5 detects an obstacle on the side of the door panel 1 or in the movement path of the door panel 1, it sends a stop signal to the drive motor 23, which promptly controls the door opening assembly 2 to stop working, avoiding safety accidents for the occupants when opening the door, and improving the safety performance of the entire door assembly.

[0044] Understandably, the aforementioned sensor 5 is either an ultrasonic radar or a displacement sensor. The ultrasonic radar and displacement sensor can be used to detect whether there are obstacles preventing the door panel 1 from opening or closing, and simultaneously acquire the distance between the obstacle and the door panel 1 and the door opening assembly 2, thereby determining whether it is necessary to promptly prevent the door opening assembly 2 from opening the door panel 1 or to adjust the speed at which the door opening assembly 2 opens the door panel 1.

[0045] When the door panel 1 encounters an obstacle while opening or closing, or when opening the door panel 1 does not meet safety requirements, the aforementioned door assembly further includes an alarm (not shown) to visually alert the user. The alarm is connected to the door controller 9, which controls the alarm to issue a warning based on the sensing signal from the sensor 5. When there is an obstacle near the door panel 1 that obstructs its opening or closing, the door controller 9 sends a stop signal to the drive motor 23 and simultaneously sends an alarm signal to the alarm, reminding the driver and passengers of the obstacle and preventing them from accidentally continuing to open the door, thus avoiding a safety accident and further improving the safety of the entire door assembly.

[0046] To ensure the safety of passengers when exiting the vehicle, it is necessary to assess whether opening the door is appropriate based on the vehicle's surroundings. Therefore, please refer to the following further information. Figure 9 The vehicle network of this application also includes a vehicle controller 6, a sensing radar 8 located at the rear of the vehicle, and a vehicle radar controller 7. The sensing radar 8 is connected to the vehicle radar controller 7, and the vehicle controller 6 is electrically connected to the vehicle radar controller 7. The sensing radar 8 is used to sense whether there is a moving obstacle approaching behind the vehicle. When the driver or passenger opens the door panel 1 from inside the vehicle or opens the door panel 1 via remote control, the vehicle controller 6 controls the vehicle radar controller 7 to directly activate the sensing radar 8. When a moving obstacle or other vehicle approaches from behind the vehicle, the sensing radar 8 sends an obstacle signal back to the vehicle controller 6. The vehicle controller 6 then stops the drive motor 23 in the door opening assembly 2 and sends a signal to the alarm to prevent the door from colliding with the moving obstacle.

[0047] Preferably, the vehicle can be equipped with both sensor 5 and sensing radar 8. When the driver or passengers open the door panel 1 from inside the vehicle or via remote control, the vehicle controller 6 controls the vehicle radar controller 7 to directly activate the sensing radar 8, and simultaneously controls the door controller 9 to activate sensor 5. This allows for simultaneous sensing of the rear of the vehicle and the sides of the door panel 1, determining the presence of obstacles or other dangerous situations such as approaching vehicles. When a moving obstacle appears behind the vehicle and approaches it, the sensing radar 8 sends an obstacle signal back to the vehicle controller 6. The vehicle controller 6 then controls the door controller 9, which in turn stops the drive motor 23 in the door opening assembly 2 and sends a signal to the alarm, preventing the door from directly opening and colliding with a movable obstacle or causing danger to the driver or passengers exiting the vehicle.

[0048] Alternatively, the aforementioned door controller 9 and the aforementioned vehicle controller 5 can share the same one. When both sensor 5 and sensing radar 8 are installed, the sensor 5 and sensing radar 8 can be directly controlled through the vehicle controller 5, which integrates the door controller 9.

[0049] Understandably, during the entire process of opening or closing the door panel 1, the sensing radar 8 and sensor 5 will sense and track in real time. When there is no longer an obstacle, a stop signal will be sent to the alarm, and the alarm will stop. The driver and passengers can open the door panel 1 from inside the vehicle or perform the opening operation again via remote control.

[0050] It is understandable that when the driver or passenger closes the door panel 1 inside the vehicle or closes the door panel 1 via remote control, the sensing and control scheme is similar to the above logic, and will not be repeated here.

[0051] Example 2:

[0052] In Embodiment 2, the difference between the first and second door assemblies and Embodiment 1 is that the driven arms 22 of the first and second door assemblies must be configured as a first arm 221 and a second arm 222 that are telescopically or pivotally connected to each other; and the second end of the stabilizing arm 3 is movably connected to the door panel 1 through a protrusion and a guide rail groove 30. Specifically, the stabilizing arm 3 is provided with a guide rail groove 30, and the door panel 1 is provided with a protrusion (not shown in the figure). The protrusion is installed in the guide rail groove 30 and can slide along the guide rail groove 30. During the opening or closing of the door panel 1, the protrusion slides along the guide rail groove 30. During the process of the drive motor 23 driving the drive arm 21 to rotate, the drive arm 21 drives the driven arm 22 to rotate synchronously, and the stabilizing arm 3 rotates synchronously with the door panel 1. The specific structure has been described in detail in Embodiment 1 and will not be repeated here.

[0053] Preferably, the protrusion is a pulley, which is pivotally connected to the door panel 1 and slidably installed in the guide rail groove 30. During the opening or closing of the door panel 1, the pulley and the door panel 1 rotate relative to each other, which facilitates the adjustment of the angle of the door panel 1. The pulley is in the guide rail groove 30 and can slide along the guide rail groove 30. During the process of the drive motor 23 driving the drive arm 21 to rotate, the drive arm 21 drives the driven arm 22 to rotate synchronously, and the stabilizing arm 3 rotates synchronously with the door panel 1.

[0054] In addition, the first door assembly and the second door assembly also include an electric strut 24. Please refer to... Figure 4 , Figure 4 yes Figure 1 A schematic diagram of another embodiment of the door opening assembly described herein. An electric strut 24 is fixed to the vehicle body 4. The electric strut 24 includes a telescopic strut portion 241, which is fixedly connected to the door panel 1. The electric strut 24 assists the drive motor 23 in driving the door panel 1 away from the vehicle body 4.

[0055] At this time, whether the first door panel 43 or the second door panel 44 is opened, the telescopic support rod 241 of the electric support rod 24 prioritizes moving the door panel 1 a certain distance away from the vehicle body 4. The protrusion moves a certain distance away from the vehicle body 4 within the guide rail groove 30, so that the door panel 1 forms a certain angle with the vehicle body 4. For the first door panel 43 and the second door panel 44, the ends of the two door panels 1 forming the angle with the vehicle body 4 can be opposite ends or opposite ends. After reaching the preset angle, under the combined action of the extension of the support rod 241 of the electric support rod 24 and the drive motor 23, the door panel 1 is driven to rotate relative to the vehicle body 4, and then moves along the length direction of the vehicle body 4 while rotating relative to the vehicle body 4 until the door opening 40 is opened. The protrusion moves synchronously within the guide rail groove 30 towards the vehicle body 4, completing the opening of the door panel 1 and retracting it towards the vehicle body 4.

[0056] It should be noted that, in order to simplify the structure and door opening movement and save costs, most vehicles in this first design case adopt the structure described in Embodiment 1 above for the door assembly.

[0057] [Second Design Scenario]

[0058] Because modern vehicle design also prioritizes aesthetics and a streamlined body, most vehicles employ the second design configuration. In this second design configuration, interference exists between the first door panel 43 of the first door assembly and the second door panel 44 of the second door assembly. That is, parts of the edges of the first door panel 43 and the second door panel 44 overlap, meaning their opposite edges intersect. In this case, to ensure that both the first door panel 43 and the second door panel 44 can be opened independently, at least one of the first door assembly and the second door assembly must employ the door assembly described in Embodiment 2.

[0059] For example, the end of the first door panel 43 facing the second door panel 44 overlaps the outer wall of the second door panel 44, where the outer wall of the second door panel 44 is the wall facing away from the vehicle interior. In this case, when the second door panel 44 needs to be opened separately, because the end of the first door panel 43 is pressing against the outer wall of the second door panel 44, the pressure from the end of the first door panel 43 must be avoided first; that is, the interference between the first door panel 43 and the second door panel 44 must be released before the second door panel 44 can be opened. Therefore, in this second design scenario, the structure of the second door assembly must adopt the structure described in Embodiment 2 of the first design scenario above. The specific structural components and connection relationships will not be elaborated here. The structure of the first door assembly can adopt the structure described in Embodiment 1 of the first design scenario above, or it can adopt the structure described in Embodiment 2 of the first design scenario above.

[0060] Preferably, in order to simplify the structure and door opening movement and save costs, the structure of the first door assembly adopts the structure described in Embodiment 1 of the first design scenario above.

[0061] At this point, please refer to the reference. Figures 6 to 8 , Figure 6 This is a first door opening diagram of another embodiment of the door assembly provided in this application; Figure 7 yes Figure 6 A schematic diagram of the second door opening mechanism of the door assembly described herein; Figure 8 yes Figure 6 The diagram illustrates the third door opening mechanism of the door assembly described herein. When it is necessary to open the second door panel 44, as shown... Figure 6As shown, the drive motor 23 and the electric strut 24 are turned on simultaneously. At this time, the drive motor 23 drives the drive arm 21 and the driven arm 22 to rotate, while the electric strut 24 drives the strut part 241 to retract. Under the drive of the drive arm 21 and the driven arm 22, the second door panel 44 rotates around the connection between the second door panel 44 and the body 4 to move away from the body 4. However, since the retraction of the strut part 241 generates a pulling force towards the inside of the body 4, the second door panel 44 rotates and deviates from the first door panel 43, causing the edges of the second door panel 44 and the first door panel 43 to no longer overlap. Furthermore, the drive motor 23 continuously drives the drive arm 21 and the driven arm 22 to move, causing the second door panel 44 to deflect away from the first door panel 43 along the vehicle body 4. Simultaneously, the protrusion moves away from the vehicle body 4 within the guide rail groove 30 until it reaches an end point near the second door panel 44, i.e., the protrusion reaches a preset position, i.e., until the edges of the second door panel 44 and the first door panel 43 do not overlap along the projection perpendicular to the vehicle body 4. Then, as... Figure 7 As shown, the strut 241 extends, and the drive motor 23 continues to drive the drive arm 21 and driven arm 22 to move. Simultaneously, the extendable strut 241, powered by the electric strut 24, moves the second door panel 44 a certain distance away from the vehicle body 4. The protrusion remains stationary in the guide rail groove 30 near the end of the second door panel 44 until a certain misalignment occurs between the second door panel 44 and the first door panel 43. Then, under the combined action of the electric strut 24 and the drive motor 23, the second door panel 44 moves to the point where the second door panel 44 opens the second door opening 42. Figure 8 As shown, the second door panel 44 reaches the preset position in the length direction of the body 4. At this time, the stabilizer arm 3 rotates to the maximum rotation angle, fully opening the second door panel 44 and completing the independent opening of the pressed second door panel 44.

[0062] Preferably, the protrusion is a pulley, which is pivotally connected to the door panel 1 and slidably installed in the guide rail groove 30. During the opening or closing of the door panel 1, the pulley and the door panel 1 rotate relative to each other, which facilitates the adjustment of the angle of the door panel 1. The pulley slides in the guide rail groove 30 and can slide along the guide rail groove 30. The pulley moves away from the vehicle body 4 in the guide rail groove 30, causing the second door panel 44 to rotate and deviate from the first door panel 43, so that the edges of the second door panel 44 and the first door panel 43 no longer overlap. The drive motor 23 continues to drive the drive arm 21 to rotate, while the support rod 241 extends, prioritizing the movement of the second door panel 44 a certain distance away from the vehicle body 4. The pulley moves away from the vehicle body 4 within the guide rail groove 30 until it reaches the end point near the second door panel 44. The drive arm 21 drives the driven arm 22 to rotate synchronously, and the stabilizing arm 3 rotates synchronously with the door panel 1, reaching the preset position where the second door panel 44 moves in the length direction relative to the vehicle body 4. At this point, the stabilizing arm 3 rotates to the maximum rotation angle, fully opening the second door panel 44 and completing the independent opening of the pressed second door panel 44.

[0063] Understandably, in practical applications, the second door panel 44 can be either the front door or the rear door of the vehicle. In other words, when pursuing aesthetic design, the edge of the front door can be overlapped with the edge of the rear door, or vice versa, depending on the actual needs of the vehicle model.

[0064] Furthermore, in the second design scenario, both the first door assembly and the second door assembly can adopt a door opening assembly 2 with an electric strut 24. That is, when the first door panel 43 and the second door panel 44 are opened, they are separated by a certain distance before rotating to open. In this case, the opening method of the first door panel 43 and the second door panel 44 is the same as the opening method described above where only the second door panel 44 adopts the door opening assembly 2 with an electric strut 24, and will not be repeated here.
