Description

Technical Field

[0001] This application relates to the field of vehicle door technology, and more particularly to a vehicle door assembly, a vehicle door, and a vehicle. Background Technology

[0002] Some door assemblies in related technologies often include multiple doors that can be combined to close the cabin together. For example, a top-and-bottom tailgate includes a top door and a bottom door that can be combined to close the rear compartment together.

[0003] However, in the relevant technology, personnel need to trigger the switches of multiple doors separately to unlock multiple doors in sequence in order to unlock the entire door assembly, making the operation of unlocking the door assembly quite cumbersome. Utility Model Content

[0004] This application provides a door assembly, a door, and a vehicle, which simplifies the operation of unlocking the door assembly.

[0005] In a first aspect, this application provides a vehicle door assembly, comprising a first door and a second door. The first door includes a first door body, a drive mechanism, and a first switch. Both the drive mechanism and the first switch are disposed on the first door body. The first switch is configured to control the unlocking of the first door and is connected to the drive mechanism, configured to control the output end of the drive mechanism to move relative to the first door body. The second door includes a second door body and a second switch. The second door body is configured to engage with the first door body to jointly close the vehicle cabin. The second switch is disposed on the second door body and configured to control the unlocking of the second door. The output end of the drive mechanism is configured to trigger the second switch or to be detached from the second switch.

[0006] The door assembly provided in this application has a first switch that controls both the unlocking of the first door and the movement of the output end of the drive mechanism relative to the first door body. This movement triggers a second switch, thereby unlocking the second door body. Thus, by triggering the first switch, a person can unlock both the first and second doors. In other words, during the unlocking process, a person does not need to trigger the switches of multiple doors separately; by triggering the first switch, the entire door assembly can be unlocked, simplifying the unlocking operation. Therefore, the door assembly provided in this application simplifies the unlocking process.

[0007] In some possible implementations of this application, when the door assembly is closed, the output of the drive mechanism faces the second switch.

[0008] In this way, with the door assembly closed, the position of the drive mechanism's output end allows it to easily reach the second switch. This means that shortly after a person triggers the first switch, the drive mechanism's output end can quickly activate the second switch, even when the first door is only partially open or not yet open at all. This reduces the difficulty of control. Understandably, if the first door is open significantly, the position of the drive mechanism's output end relative to the second switch becomes difficult to control precisely. Controlling the drive mechanism's output end to point towards and trigger the second switch in this situation is much more challenging.

[0009] In some possible implementations of this application, the edge of the first door body includes a first overlapping portion, the edge of the second door body includes a second overlapping portion, and when the door assembly is closed, the first overlapping portion and the second overlapping portion overlap along the thickness direction of the door assembly, and the output end of the drive mechanism and the second switch are both located between the first overlapping portion and the second overlapping portion.

[0010] With the door assembly closed, the first and second overlapping portions overlap along the thickness direction of the door assembly, resulting in better sealing and preventing impurities from the external environment from easily penetrating the gap between the first and second door panels and entering the passenger compartment. By positioning the output end of the drive mechanism and the second switch both between the first and second overlapping portions, the distance between them is reduced, allowing the output end of the drive mechanism to trigger the second switch with a smaller movement. This improves the rigidity and accuracy of the drive mechanism's output end. Furthermore, the location of both the output end and the second switch between the first and second overlapping portions also allows them to conceal and protect the drive mechanism and the second switch, enhancing their reliability and ensuring a smoother outer surface of the door assembly when closed.

[0011] In some possible implementations of this application, the second overlapping portion has a button hole facing the first overlapping portion. The second switch includes a button disposed within the button hole.

[0012] By incorporating a button into the second switch, and forming a button hole in the second overlapping portion, with the button disposed within the button hole, the structure of the second switch is simplified. Furthermore, along the thickness direction of the second door body, the length of the second switch protruding relative to the second overlapping portion is small, or nonexistent. This reduces the likelihood of significant interference between the first overlapping portion and the second switch, and the placement of the second switch minimizes the tight contact between the first and second overlapping portions. This improves the sealing of the door assembly, preventing impurities from the external environment from easily penetrating the gap between the first and second door bodies and entering the passenger compartment. Moreover, the button is triggered by pressing, with the output end of the drive mechanism activating the button. This simplifies the movement of the drive mechanism's output end, further simplifying its structure.

[0013] It is understood that, in the embodiments of this application, the output end of the drive mechanism is configured to be able to press a button in the direction from the first overlapping portion to the second overlapping portion to unlock the second door.

[0014] In some possible implementations of this application, the first overlapping portion forms a receiving cavity with an opening facing the second overlapping portion, and a driving mechanism is disposed within the receiving cavity.

[0015] By placing the drive mechanism within the receiving cavity, the degree of protrusion of the drive mechanism relative to the first overlapping portion can be reduced, making it less likely for the drive mechanism to interfere significantly with the second overlapping portion. This allows the first and second overlapping portions to fit together more tightly, resulting in a smaller gap between them, which improves the sealing performance of the door assembly. Furthermore, by having an opening in the receiving cavity facing the second overlapping portion, the output end of the drive mechanism can extend through the opening and reach the second switch, enabling the drive mechanism to trigger the second switch normally.

[0016] In some possible implementations of this application, the first door body is configured to be rotatably connected to the vehicle body about a first axis, the first axis being perpendicular to the thickness direction of the first door body and located at one end of the door assembly. The first overlapping portion is located on the side of the second overlapping portion away from the vehicle compartment.

[0017] Thus, the first door is a revolving door, meaning it opens and closes through a rotating motion relative to the vehicle body. Compared to a sliding door, which opens and closes by sliding relative to the vehicle body, the solution in this application is less expensive, provides better rigidity to the vehicle body, and makes opening the door more convenient. The hinge mechanism of a revolving door is mature and simple, with low manufacturing costs, while a sliding door requires complex tracks, rollers, and stabilizing mechanisms. The tracks must be long and robust, increasing manufacturing costs and weight. The door frame of a revolving door is a relatively complete unit, providing better structural rigidity to the vehicle body. A revolving door requires less lateral space to open, making it easier to open even in confined spaces.

[0018] Furthermore, by positioning the first overlapping portion on the side of the second overlapping portion away from the vehicle cabin, during the process of opening the door assembly, the first door can be opened first, removing the obstruction of the second overlapping portion by the first overlapping portion, and then the second door can be opened. In other words, the process of opening the door assembly can involve opening the first door first and then the second door. This allows the first door to open quickly after a person triggers the first switch, without waiting for the second door to open, thus reducing the time required to open the door assembly. It is understood that the time required for a person to trigger the second door to open is relatively long. After a person triggers the first switch, the first switch first triggers the movement of the output end of the drive mechanism, then the output end of the drive mechanism triggers the second switch, and only then can the second door open. However, after a person triggers the first switch, the first switch can directly control the unlocking of the first door, after which the first door can open. The time required to trigger the opening of the first door is relatively short. Therefore, compared to opening the second door first and then waiting for it to open before opening the first door, the time required to open the door assembly in this embodiment is relatively short.

[0019] In some possible implementations of this application, the second door is configured to be rotatably connected to the vehicle body about a second axis, the second axis being parallel to the first axis, the first axis and the second axis being located at opposite ends of the door assembly, the first overlapping portion being located at the end of the first door away from the first axis, and the second overlapping portion being located at the end of the second door away from the second axis.

[0020] In this way, the first door can be opened to a relatively small extent, and the obstruction of the first overlapping part on the second overlapping part can be released, allowing the second door to open. The second door does not need to wait for the first door to open fully before opening, thus reducing the time required to open the car door assembly and minimizing waiting time for passengers. Moreover, in this application, after a person triggers the first switch, the time required to trigger the opening of the first door is relatively short, while the time required to trigger the opening of the second door is relatively long. The second door is only triggered after the first door has opened to a certain extent. In this case, the obstruction of the first overlapping part on the second overlapping part can be released, which helps to reduce the risk of interference between the first and second doors during the opening of the car door assembly.

[0021] In some possible implementations of this application, the drive mechanism includes a fixed part and a movable part. The fixed part is fixedly connected to the first door body, the movable part is slidably connected to the fixed part, and the output end of the drive mechanism is formed in the movable part.

[0022] In this way, the movable part can trigger the second switch or separate from the second switch by sliding relative to the fixed part. The movement of the movable part is relatively simple, which makes the structure of the drive mechanism simple and the cost low.

[0023] In some possible implementations of this application, the drive mechanism includes a fixed part and a movable part. The fixed part is fixedly connected to the first door body, the movable part is constructed as a swing arm, one end of the swing arm is rotatably connected to the fixed part, and the output end of the drive mechanism is formed at the other end of the swing arm.

[0024] In this way, the movable part can trigger the second switch or separate from the second switch by swinging relative to the fixed part. The movement of the movable part is relatively simple, which makes the structure of the drive mechanism simple and the cost low.

[0025] Secondly, this application provides a vehicle door, which includes a first door body, a drive mechanism, and a first switch. The first door body is configured to engage with a second door body to jointly close the vehicle cabin. The drive mechanism is disposed on the first door body, and the first switch is disposed on the first door body and configured to control the unlocking of the first door body. The first switch is connected to the drive mechanism and configured to control the output end of the drive mechanism to move relative to the first door body. The output end of the drive mechanism is configured to trigger a second switch or to separate from the second switch. The second switch is disposed on the second door body and configured to control the unlocking of the second door body.

[0026] The vehicle door provided in this application includes a first door body, a drive mechanism, and a first switch. The first switch controls both the unlocking of the first door and the movement of the output end of the drive mechanism relative to the first door body. When the output end of the drive mechanism moves relative to the first door body, it triggers a second switch, thereby unlocking the second door body. Thus, by triggering the first switch, a person can unlock both the first and second doors. In other words, during the unlocking process of the door assembly, which includes both the first and second door bodies, a person does not need to trigger the switches of multiple doors separately; by triggering the first switch, the entire door assembly can be unlocked, simplifying the unlocking operation. Therefore, the door assembly provided in this application simplifies the unlocking operation of a vehicle door assembly.

[0027] Thirdly, this application provides a vehicle that includes the door assembly provided in the first aspect of this application.

[0028] The vehicle provided in this application, including the door assembly provided in the first aspect of this application, can achieve the same technical effect, namely, it can simplify the operation of unlocking the door assembly. Attached Figure Description

[0037] Some door assemblies in related technologies often consist of multiple doors that are assembled together to close the vehicle cabin. However, unlocking the door assembly requires personnel to trigger the switches of multiple doors individually to unlock the entire assembly, making the process cumbersome.

[0038] This application provides a vehicle, which, by way of example, can be an off-road vehicle, a sport utility vehicle (SUV), a multi-purpose vehicle (MPV), a bus, or a truck.

[0039] Please refer to Figure 1 and Figure 2 This application provides a vehicle including a door assembly. The door assembly includes a first door 1 and a second door 2. The first door 1 includes a first door body 11, a drive mechanism 12, and a first switch 13. The drive mechanism 12 and the first switch 13 are both disposed on the first door body 11. The first switch 13 is configured to control the unlocking of the first door 1. The first switch 13 is connected to the drive mechanism 12 and configured to control the output end of the drive mechanism 12 to move relative to the first door body 11. The second door 2 includes a second door body 21 and a second switch 22. The second door body 21 is configured to be joined with the first door body 11 to jointly close the vehicle compartment. The second switch 22 is disposed on the second door body 21 and configured to control the unlocking of the second door body 21. The output end of the drive mechanism 12 is configured to trigger the second switch 22 or to separate from the second switch 22.

[0040] The door assembly provided in this application embodiment has a first switch 13 that controls the unlocking of the first door 1 and also controls the movement of the output end of the drive mechanism 12 relative to the first door body 11. This movement of the output end of the drive mechanism 12 relative to the first door body 11 triggers the second switch 22, thereby unlocking the second door body 21. Thus, by triggering the first switch 13, a person can unlock both the first door 1 and the second door 2. In other words, during the unlocking process, a person does not need to trigger the switches of multiple doors separately; by triggering the first switch 13, the entire door assembly can be unlocked, simplifying the unlocking operation. Therefore, the door assembly provided in this application embodiment simplifies the unlocking operation of the door assembly.

[0041] Furthermore, please refer to Figure 1 and Figure 2 In this embodiment, the output end of the drive mechanism 12 moves relative to the first door 11 and triggers the second switch 22 mechanically to unlock the second door 22. This reduces reliance on electronics, increases reliability, and does not require major adjustments to the electronic system. The drive mechanism 12 can be added to the first door 1.

[0042] Please refer to Figure 1 and Figure 2 In some embodiments of this application, the door assembly can be a top-and-bottom door type rear door, where the first door 1 is the top door and the second door 2 is the bottom door. The first door 1 is rotatably connected to the vehicle body around a first axis, and the second door 2 is rotatably connected to the door around a second axis. Both the first axis and the second axis are parallel to the vehicle width direction y. When the door assembly is closed, the first axis is located at the top of the first door 1 and the second axis is located at the bottom of the second door 2.

[0043] Please refer to Figure 1 and Figure 2 In some embodiments of this application, the first door 1 may be a bottom door and the second door 2 may be a top door. The first door 1 is rotatably connected to the vehicle body around a first axis, and the second door 2 is rotatably connected to the door around a second axis. Both the first axis and the second axis are parallel to the vehicle width direction y. When the door assembly is closed, the first axis is located at the bottom of the first door 1 and the second axis is located at the top of the second door 2.

[0044] Please refer to Figure 1 and Figure 2 In some embodiments of this application, the vehicle door assembly is a rear door, and the first switch 13 can be located on the surface of the first door 1 away from the vehicle cabin. This facilitates operation by personnel.

[0045] Please refer to Figure 1 and Figure 2In some embodiments of this application, the first switch 13 includes an input element, a detection module, and a first control module. The input element is used to be pressed, and the detection module is connected to the input element. The detection module can be used to detect the number of times the input element is pressed within a first preset time period, or it can be used to detect the duration of the input element being pressed, etc. The first control module is configured to control the drive mechanism 12 according to the detection result of the detection module. For example, please refer to... Figure 3 If the input device is pressed once within a first preset time period, for example, once within one second, the drive mechanism 12 is not activated, thus unlocking the first door 1 and keeping the second door 2 locked. Alternatively, if the input device is pressed twice within a first preset time period, for example, twice within one second, the drive mechanism 12 is activated, thus unlocking both the first door 1 and the second door 2.

[0046] Please refer to Figure 4 , Figure 5 and Figure 6 In some embodiments of this application, the first control module can also be connected to a driver, which is configured to move the first door 1 relative to the vehicle body, switching the first door 1 between an open state and a closed state. The driver is also configured to move the second door 2 relative to the vehicle body, switching the second door 2 between an open state and a closed state. For example, please refer to... Figure 4 and Figure 5 In some embodiments of this application, the car door assembly is a top-and-bottom rear door. When the input device is pressed for a duration exceeding a second preset duration, such as a long press exceeding two seconds, the first control module can control the top door to unlock and open to a preset angle, and the bottom door to unlock. The preset angle can be calibrated by the user, for example, from 30 to 45 degrees. The opening angle of the top door is 30 to 45 degrees, which can reduce the risk of interference between the bottom door and the top door during the opening process. Please refer to [the relevant documentation] in some embodiments of this application. Figure 6 If the input device is pressed three times within a first preset time period, for example, three times within one second, the first control module can control both the top door and the bottom door to unlock and fully open.

[0047] Please refer to Figure 4 , Figure 5 and Figure 6In some embodiments of this application, the first switch 13 may include a touch screen and a second control module. The touch screen has an interaction unit, the second control module is connected to the touch screen, the second control module is connected to the drive mechanism 12, the second control module is connected to the driver, and the second control module is connected to the door lock of the first door 1. When the interaction unit is operated, the touch screen outputs an instruction to unlock the door assembly. The second control module controls at least one of the door lock, drive mechanism 12, and driver of the first door 1 according to the instruction output by the touch screen, so as to unlock the first door 1 and keep the second door 2 locked, or both the first door 1 and the second door 2 are unlocked, or both the first door 1 and the second door 2 are unlocked and the first door 1 is opened to a preset angle.

[0048] Please refer to Figure 1 and Figure 2 In some embodiments of this application, the first switch 13, the drive mechanism 12, the door lock of the first door 1, and the driver can be connected via a controller area network (CAN). The second switch 22, the door lock of the second door 2, and the driver can also be connected via a controller area network (CAN).

[0049] Please refer to Figure 1 and Figure 2 In some embodiments of this application, when the door assembly is closed, the output of the drive mechanism 12 faces the second switch 22.

[0050] In this way, with the door assembly closed, the position of the output end of the drive mechanism 12 allows it to easily reach the second switch 22. This enables the output end of the drive mechanism 12 to quickly trigger the second switch 22 shortly after the person triggers the first switch 13, even when the first door 11 is still only partially open or not yet open at all. This helps reduce the difficulty of control. Understandably, if the first door 11 is open significantly, the position of the output end of the drive mechanism 12 relative to the second switch 22 becomes difficult to control precisely. Controlling the output end of the drive mechanism 12 to face and trigger the second switch 22 in this situation is more challenging.

[0051] Please refer to Figure 1 and Figure 2 In some embodiments of this application, the edge of the first door body 11 includes a first overlapping portion 111, and the edge of the second door body 21 includes a second overlapping portion 211. When the door assembly is closed, the first overlapping portion 111 and the second overlapping portion 211 overlap along the thickness direction of the door assembly. The output end of the drive mechanism 12 and the second switch 22 are both located between the first overlapping portion 111 and the second overlapping portion 211.

[0052] With the door assembly closed, the first overlapping portion 111 and the second overlapping portion 211 overlap along the thickness direction of the door assembly, resulting in better sealing of the door assembly. This prevents impurities from the external environment from easily penetrating the gap between the first door body 11 and the second door body 21 and entering the passenger compartment. By positioning the output end of the drive mechanism 12 and the second switch 22 both between the first overlapping portion 111 and the second overlapping portion 211, the distance between the output end of the drive mechanism 12 and the second switch 22 is relatively short. This allows the output end of the drive mechanism 12 to trigger the second switch 22 with a smaller movement distance, which improves the movement rigidity and accuracy of the output end of the drive mechanism 12. In addition, the output end of the drive mechanism 12 and the second switch 22 are both located between the first overlapping part 111 and the second overlapping part 211, which also allows the first overlapping part 111 and the second overlapping part 211 to hide and protect the output end of the drive mechanism 12 and the second switch 22. This is beneficial to improving the reliability of the drive mechanism 12 and the second switch 22, and also helps to make the outer surface of the door assembly relatively flat when the door assembly is closed.

[0053] Please refer to Figure 1 and Figure 2 It should be noted that, in this embodiment, the output end of the drive mechanism 12 and the second switch 22 are both located between the first overlapping portion 111 and the second overlapping portion 211. This means that when the door assembly is closed, the output end of the drive mechanism 12 and the second switch 22 are both located between the first overlapping portion 111 and the second overlapping portion 211. Please refer to Figure 1 , Figure 4 and Figure 5 In some embodiments of this application, the second overlapping portion 211 is formed with a button hole facing the first overlapping portion 111. The second switch 22 includes a button disposed in the button hole.

[0054] By including a button in the second switch 22 and forming a button hole in the second overlapping portion 211, with the button disposed within the button hole, the structure of the second switch 22 is simplified. Furthermore, the length of the second switch 22 protruding relative to the second overlapping portion 211 along the thickness direction of the second door body 21 is small, or non-protruding. This reduces the likelihood of significant interference between the first overlapping portion 111 and the second switch 22, and the arrangement of the second switch 22 does not easily affect the tight contact between the first overlapping portion 111 and the second overlapping portion 211. This improves the sealing performance of the door assembly, preventing impurities from the external environment from easily penetrating the gap between the first door body 11 and the second door body 21 and entering the passenger compartment. Moreover, the button is triggered by pressing, with the output end of the drive mechanism 12 actuating the button, simplifying the movement of the output end of the drive mechanism 12 and further simplifying its structure.

[0055] Please refer to Figure 1 , Figure 4 and Figure 5 It should be explained that, in the embodiments of this application, the button hole facing the first overlapping part 111 means that when the door assembly is closed, the button hole faces the first overlapping part 111.

[0056] Please refer to Figure 1 and Figure 2 In some embodiments of this application, the first overlapping portion 111 forms a receiving cavity with an opening facing the second overlapping portion 211, and the driving mechanism 12 is disposed in the receiving cavity.

[0057] By placing the drive mechanism 12 within the receiving cavity, the degree of protrusion of the drive mechanism 12 relative to the first overlapping portion 111 can be reduced, making it less likely for the drive mechanism 12 to interfere significantly with the second overlapping portion 211. This allows the first and second overlapping portions 111 to fit together more tightly, resulting in a smaller gap between them, which improves the sealing performance of the door assembly. Furthermore, by providing an opening in the receiving cavity facing the second overlapping portion 211, the output end of the drive mechanism 12 can extend through the opening and reach the second switch 22, enabling the drive mechanism 12 to trigger the second switch 22 normally.

[0058] Please refer to Figure 1 and Figure 2 It should be explained that, in the embodiments of this application, "opening facing the second overlapping part 211" means that when the door assembly is closed, the opening faces the second overlapping part 211.

[0059] Please refer to Figure 1 and Figure 2In some embodiments of this application, the first door body 11 is configured to be rotatably connected to the vehicle body about a first axis, the first axis being perpendicular to the thickness direction of the first door body 11 and located at one end of the door assembly. The first overlapping portion 111 is located on the side of the second overlapping portion 211 away from the vehicle cabin.

[0060] Thus, the first door 11 is a revolving door, meaning it opens and closes through a flipping motion relative to the vehicle body. Compared to a sliding door, which opens and closes by sliding relative to the vehicle body, the solution in this embodiment is less expensive, has better rigidity of the vehicle body, and is more convenient to open. The hinge mechanism of a revolving door is mature and simple, with low manufacturing costs, while a sliding door requires complex tracks, rollers, and stabilizing mechanisms. The tracks must be long and robust, increasing manufacturing costs and weight. The door frame of a revolving door is a relatively complete unit, providing better structural rigidity for the vehicle body. A revolving door requires less lateral space to open, making it easier to open even in congested environments.

[0061] Furthermore, by positioning the first overlapping part 111 on the side of the second overlapping part 211 away from the vehicle cabin, during the process of opening the door assembly, the first door body 11 can be opened first, and after the first overlapping part 111 removes the obstruction of the second overlapping part 211, the second door body 21 can be opened. In other words, the process of opening the door assembly can be such that the first door body 11 opens first, and the second door body 21 opens later. In this way, after the person triggers the first switch 13, the first door body 11 can be opened quickly without waiting for the second door body 21 to open, which helps to reduce the time required for the door assembly to open. It is understandable that the time required for a person to trigger the opening of the second door 21 is relatively long. After a person triggers the first switch 13, the first switch 13 first triggers the movement of the output end of the drive mechanism 12, and then the output end of the drive mechanism 12 triggers the second switch 22, and only then can the second door 21 be triggered to open. However, after a person triggers the first switch 13, the first switch 13 can directly control the first door 11 to unlock, and then the first door 1 can be opened. The time required to trigger the opening of the first door 11 is relatively short. Therefore, compared to opening the second door 2 first and waiting for the second door 2 to open before opening the first door 1, the time required to open the door assembly in this embodiment is relatively short.

[0062] Please refer to Figure 1 and Figure 2 It should be explained that, in the embodiments of this application, the first overlapping part 111 is located on the side of the second overlapping part 211 away from the vehicle compartment, which means that when the door assembly is closed, the first overlapping part 111 is located on the side of the second overlapping part 211 away from the vehicle compartment.

[0063] Please refer to Figure 1 and Figure 2In some embodiments of this application, the second door body 21 is configured to be rotatably connected to the vehicle body about a second axis, the second axis is parallel to the first axis, the first axis and the second axis are located at opposite ends of the door assembly, the first overlapping part 111 is located at the end of the first door 1 away from the first axis, and the second overlapping part 211 is located at the end of the second door 2 away from the second axis.

[0064] In this way, the first door 11 can be opened to a relatively small extent, and the obstruction of the first overlapping part 111 on the second overlapping part 211 can be released, allowing the second door 21 to open. The second door 21 does not need to wait for the first door 11 to be fully opened before opening, thus reducing the time required to open the car door assembly and reducing the waiting time for personnel. Moreover, in this embodiment, after a person triggers the first switch 13, the time required to trigger the opening of the first door 11 is relatively small, while the time required to trigger the opening of the second door 21 is relatively large. The second door 21 is only triggered to open after the first door 11 has opened to a certain extent. In this case, the obstruction of the first overlapping part 111 on the second overlapping part 211 can be released, which helps to reduce the risk of interference between the first door 11 and the second door 21 during the opening of the car door assembly.

[0065] Please refer to Figure 1 and Figure 2 In some embodiments of this application, the drive mechanism 12 includes a fixed part and a movable part. The fixed part is fixedly connected to the first door body 11, the movable part is slidably connected to the fixed part, and the output end of the drive mechanism 12 is formed in the movable part.

[0066] In this way, the movable part can trigger the second switch 22 or separate from the second switch 22 by sliding relative to the fixed part. The movement of the movable part is relatively simple, which makes the structure of the drive mechanism 12 relatively simple and the cost low.

[0067] Please refer to Figure 1 and Figure 2 In some embodiments of this application, the drive mechanism 12 can be a pneumatic cylinder, hydraulic cylinder, electric cylinder, or linear motor, etc. This results in a simpler structure and lower cost for the drive mechanism 12.

[0068] Please refer to Figure 1 and Figure 2 In some embodiments of this application, the drive mechanism 12 includes a fixed part and a movable part. The fixed part is fixedly connected to the first door body 11, and the movable part is constructed as a swing arm. One end of the swing arm is rotatably connected to the fixed part, and the output end of the drive mechanism 12 is formed at the other end of the swing arm.

[0069] In this way, the movable part can trigger the second switch 22 or separate from the second switch 22 by swinging relative to the fixed part. The movement of the movable part is relatively simple, which makes the structure of the drive mechanism 12 simple and the cost low.

[0070] Please refer to Figure 1 and Figure 2 In some embodiments of this application, the drive mechanism 12 includes a motor and a swing arm. The motor is disposed on the first door body 11, and the swing arm is drivenly connected to the output end of the motor, for example, it can be fixedly connected. The motor drives the swing arm to swing relative to the first door body 11. In this way, the structure of the drive mechanism 12 is relatively simple and the cost is low.

[0071] Please refer to Figure 1 and Figure 2 In some embodiments of this application, the movable part can be made of a lightweight alloy material, such as aluminum alloy, magnesium alloy, or titanium alloy. This results in a lighter movable part with higher strength and rigidity. In some embodiments of this application, the movement range of the movable part can be 5 to 10 centimeters. This moderate movement range ensures both high rigidity and reliable triggering of the second switch 22.

[0072] Please refer to Figure 1 and Figure 2 This application embodiment also provides a vehicle door, which includes a first door body 11, a drive mechanism 12, and a first switch 13. The first door body 11 is configured to assemble with a second door body 21 to jointly close the vehicle cabin. The drive mechanism 12 is disposed on the first door body 11. The first switch 13 is disposed on the first door body 11 and configured to control the unlocking of the first door body 11. The first switch 13 is connected to the drive mechanism 12 and configured to control the output end of the drive mechanism 12 to move relative to the first door body 11. The output end of the drive mechanism 12 is configured to trigger a second switch 22 or separate from the second switch 22. The second switch 22 is disposed on the second door body 21 and configured to control the unlocking of the second door body 21.

[0073] The vehicle door provided in this embodiment includes a first door body 11, a drive mechanism 12, and a first switch 13. The first switch 13 controls the unlocking of the first door 1 and also controls the movement of the output end of the drive mechanism 12 relative to the first door body 11. When the output end of the drive mechanism 12 moves relative to the first door body 11, it triggers a second switch 22, thereby unlocking the second door body 21. Thus, by triggering the first switch 13, a person can unlock both the first door 1 and the second door 2. That is, during the unlocking process of the door assembly, which includes the first door body 11 and the second door body 21, a person does not need to trigger the switches of multiple doors separately; by triggering the first switch 13, the entire door assembly can be unlocked, simplifying the unlocking operation. Therefore, the door assembly provided in this embodiment simplifies the unlocking operation of the door assembly.
