Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of automobile manufacturing, and particularly relates to a vehicle door system, an automobile, and a control method. BACKGROUND

[0002] In existing vehicle designs, vehicle door systems usually adopt traditional opening methods, such as swing doors or sliding doors. Although these designs meet basic usage requirements, they have certain limitations in providing spacious entry and exit space and improving user experience.

[0003] For ordinary consumers:

[0004] If there is a young baby in the family, an adult often needs to hold the baby or assist the baby to enter the vehicle and sit down. In this process, the opening space of the traditional vehicle door often cannot well satisfy the adult entering the vehicle while carrying a baby, resulting in crowded space or lack of effective support for the upper body when the person steps into the vehicle with one leg.

[0005] If there is an elderly person with limited mobility in the family, the elderly person often moves slowly and needs auxiliary tools to walk smoothly, such as a cane. When the elderly person gets in or out of the vehicle, in order to achieve body balance, one hand needs to hold the cane, and the other hand needs to rely on another support point to better achieve the action of getting in or out of the vehicle. Usually, the other support point is the vehicle body or the door frame position. However, the rear door of the traditional vehicle adopts a swing door design, and after the door is opened, the rear door is rotated to a position close to the front of the vehicle. There is a lack of support point position close to the rear of the vehicle, which cannot provide a balance support point for the elderly person with limited mobility.

[0006] If there is a person with lower limb hemiplegia or loss of lower limb movement function in the family due to illness, multiple people need to cooperate to move the person when getting in or out of the vehicle. At this time, in order to ensure the convenience of getting in or out of the vehicle, the front seat is often moved forward, and the traditional vehicle door is rotated to the maximum opening position. Even so, due to the influence of the opening position of the traditional swing door, the convenience of the person getting in or out of the vehicle cannot be well guaranteed.

[0007] In addition, although there are some specially designed vehicle doors on the market, such as scissor doors or gull-wing doors, these designs are often only applied to high-end or special-purpose vehicles, and usually require complex mechanical structures to achieve.

[0048] It should be noted that the following detailed description is exemplary in nature and is intended to provide further description of the application. Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs.

[0049] It is to be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of example embodiments according to the present application.

[0050] In the case of no conflict, the embodiments in the present application and the features in the embodiments can be combined with each other.

[0051] Term explanation:

[0052] Electric scissor door opening mode: up and down opening along the body to the upper side.

[0053] Electric swing door opening mode: rotating to open inside or outside the body.

[0054] Electric parallel door opening mode: opening with the rear end of the door as the axis.

[0055] Electric swing door opening mode: in the present application, it is an outswing door, specifically, swinging to open outside the body.

[0056] Embodiment one

[0057] As described in the foregoing background, the traditional opening mode such as the swing door or the sliding door, although meets the basic use requirements of the user, has certain limitations in providing spacious access space and improving the user experience.

[0058] If there is a young baby in the family, an adult often needs to hold the baby or assist the baby to enter the vehicle and sit down, and in this process, the opening space of the traditional vehicle door often cannot well meet the adult entering the vehicle while carrying a baby, causing space congestion or the upper body of the person stepping into the vehicle with one leg lacking an effective support point.

[0059] If there is an old person with poor mobility in the family, the old person often moves slowly and needs auxiliary tools such as a walking stick to walk smoothly. When the old person gets in and out of the vehicle, in order to achieve body balance, one hand needs to hold the walking stick, and the other hand needs to rely on another support point to better achieve the action of getting in and out of the vehicle. Usually, the other support point is the position of the vehicle body or the door frame. However, the rear door of the traditional vehicle adopts a swing door design, and after the door is opened, the rear door is rotated to a position close to the front of the vehicle. There is a lack of support point position close to the rear of the vehicle, which cannot provide a balance support point for the old person with poor mobility.

[0060] If there is a person with lower limb hemiplegia or loss of lower limb movement function in the family due to disease, multiple people need to cooperate to move the person when getting in and out of the vehicle. At this time, in order to ensure the convenience of getting in and out of the vehicle, the front seat often needs to be moved forward, and the traditional door is rotated to the maximum opening position. Even so, due to the influence of the opening position of the traditional swing door, the convenience of the person getting in and out of the vehicle cannot be well guaranteed.

[0061] In summary, the existing vehicle door system still has some deficiencies in space experience and meeting the safety of getting in and out of the vehicle for various different users.

[0062] Based on this, the embodiment discloses a vehicle door system.

[0063] As shown in Figure 1 , Figure 2 , Figure 3 and Figure 4 , a vehicle door system includes a front door and a rear door. The front door is a double-wing door, and the rear door is a double-wing door or an electric swing door.

[0064] The front door and the vehicle body are connected through a first conversion device, and the first conversion device is used to convert the opening mode of the front door between an electric scissor door opening mode and an electric swing door opening mode.

[0065] When the rear door is a double-wing door, the rear door is connected to the vehicle body through a second conversion device, which is used to switch the opening mode of the rear door between an electric double-leaf door opening mode and an electric swing door opening mode.

[0066] When the rear door is an electric swing door, the front end of the rear door is rotatably connected to the vehicle body.

[0067] It can be understood that when the rear door is an electric swing door, the front end of the rear door is rotatably connected to the vehicle body through a rotating connection device.

[0068] like Figure 1 As shown in the illustration, this embodiment features an electric swing door for the front and an electric swing door for the rear. With both doors open, the vehicle's space for passengers getting in and out is significantly improved compared to traditional methods. The rear door, which moves outwards and to the rear of the vehicle, also provides an effective support point for passengers. This ensures maximum safety and convenience for passengers getting in and out, whether they are carrying infants, elderly people with mobility issues, or people with lower limb disabilities.

[0069] It can be understood that the above Figure 1 (a), (b), (c), and (d) in the figures are, respectively, a three-dimensional view, a top view, a front view, and a side view when the front door is an electric swing door and the rear door is an electric swing door.

[0070] like Figure 2 As shown, in this embodiment, the front door is an electric swing door and the rear door is an electric double door. This scenario differs from the one described above. Figure 1 Because the rear door extends outwards, it provides an effective support point for people getting on and off the bus, making it especially suitable for elderly people with mobility issues. It also provides anti-tipping protection for people carrying infants and young children, thus improving the overall safety and convenience of getting on and off the bus.

[0071] It can be understood that the above Figure 2 (a), (b), (c), and (d) in the figures are, respectively, a three-dimensional view, a top view, a front view, and a side view of the electric swing door opening mode plus the electric double-door opening mode of the rear door.

[0072] like Figure 3 As shown, this embodiment features an electric scissor door for the front and an electric swing door for the rear. With this configuration, after the doors are opened, the front seats can be moved forward and the rear seats backward, facilitating entry and exit for individuals with lower limb mobility impairments and providing them with as much lower body space as possible. This scenario differs from the aforementioned... Figure 1 and Figure 2In this scenario, the front door opens diagonally upwards, thus providing a larger lower seating space, making it easier for people with lower limb motor disabilities or difficulty getting on and off the vehicle.

[0073] It can be understood that the above Figure 3 (a), (b), (c), and (d) are, respectively, a three-dimensional view, a top view, a front view, and a side view when the front door is an electric scissor door and the rear door is an electric swing door.

[0074] like Figure 4 As shown, in this embodiment, the front door is an electric scissor door and the rear door is an electric double-door. When the rear door is opened, it can also provide an effective support point for extending outward and provide a large lower opening space, thereby improving the safety and convenience of people getting on and off the vehicle.

[0075] It can be understood that the above Figure 4 (a), (b), (c), and (d) are, respectively, a three-dimensional view, a top view, a front view, and a side view when the front door is an electric scissor door and the rear door is an electric double door.

[0076] In some embodiments, the first conversion device includes a driver A and a driver B, wherein the driver A is used to control the opening or locking of the electric scissor door, and the driver B is used to control the opening or locking of the electric swing door.

[0077] It can be understood that the first conversion device in this embodiment also includes an electric scissor door opening transmission device and an electric swing door opening transmission device. To enable the first conversion device to switch the front door opening mode between electric scissor door opening mode and electric swing door opening mode, this embodiment provides two drivers, namely driver A and driver B. When driver A is open and driver B is locked, the door will be controlled to open in the electric scissor door opening mode; conversely, when driver A is locked and driver B is open, the door will be controlled to open in the electric swing door opening mode.

[0078] More specifically, such as Figure 5As shown, the first conversion device in this embodiment can adopt existing technology, such as the Chinese invention patent application published on May 7, 2024, with publication number CN 117988650 A, filed by Chery Automobile Co., Ltd., which discloses a door opening and closing device, a vehicle, and a vehicle control method. In the door opening and closing device, a first door component 2 is rotatably connected to a body component 1, a second door component 3 is connected to the first door component 2, one end of a scissor door drive component 4 is connected to the body, and the other end is connected to the first door component 2. One end of a swing door drive component 5 is connected to the first door component 2, and the other end is connected to the second door component 3.

[0079] The switching element 6 is disposed on the second door component 3. The switching element 6 is used to control the switching between the first door component 2 and the second door component 3 between rigid connection and rotational connection, thereby switching the door opening and closing device between scissor door mode and swing door mode.

[0080] The door opening and closing device has a scissor door mode and a swing door mode. In the scissor door mode, the first door component 2 and the second door component 3 are rigidly connected, and the scissor door drive component 4 drives the first door component 2 and the second door component 3 to move synchronously to achieve scissor-type opening and closing. In the swing door mode, the first door component 2 and the second door component 3 are rotatably connected, and the swing door drive component 5 drives the second door component 3 to rotate relative to the first door component 2 to achieve translational opening and closing.

[0081] The scissor door drive 4 and the swing door drive 5 in the above patent are respectively equivalent to the driver A and driver B of the first conversion device in this embodiment; the door opening and closing device described in the above patent is equivalent to the first conversion device in this embodiment.

[0082] The specific structural design in the aforementioned patent will not be elaborated further in this embodiment.

[0083] In some embodiments, the second conversion device includes a driver C and a driver D, wherein the driver C is used to control the opening or locking of the electric double door opening mode, and the driver D is used to control the opening or locking of the electric swing door opening mode.

[0084] like Figure 6 The diagram shown is a schematic of the second conversion device for the rear door in this embodiment. The second conversion device includes a first hinge 7, a driver D8, a first hinge fixing plate 9, a vehicle body side mounting plate 10, a driver C11, and a second hinge 12.

[0087] As shown in Figure 6 , the first hinge 7 is connected with the door through the first hinge fixed leaf plate 9, the driver D8 is connected with the first hinge 7, the driver D8 is used to drive the first hinge 7 to displace, and the first hinge 7 is used to drive the door to rotate relative to the vehicle body under the driving of the driver D8.

[0088] When the driver D8 is opened, the first hinge 7 will be displaced, and the door will be rotated relative to the vehicle body, so as to realize the electrically opening mode of the electrically opening and closing door.

[0089] The driver C11 is connected with the vehicle body, the output end of the driver C11 is connected with the door through the second hinge 12, the driver C11 is used to drive the second hinge 12 to displace, and the second hinge 12 is used to drive the door to move backward relative to the vehicle body under the driving of the driver C11.

[0090] In this way, when the driver C11 is opened, the second hinge 12 will be displaced, and the door will be moved backward relative to the vehicle body, so as to realize the electrically opening mode of the electrically swinging door.

[0091] It can be understood that the vehicle body side mounting leaf plate 10 is arranged on the vehicle body, and the driver C11 is connected with the vehicle body through the vehicle body side mounting leaf plate 10.

[0092] The first hinge 7 and the second hinge 12 in the embodiment are used as transmission devices, and can adopt the prior art, as long as the displacement of the first hinge 7 and the second hinge 12 can realize the corresponding opening mode of the door. The embodiment does not make any limitation in this regard.

[0100] The embodiment discloses a vehicle.

[0101] The vehicle comprises the vehicle door system as described in Embodiment One.

[0102] Embodiment Three

[0103] The embodiment discloses a vehicle door system control method.

[0104] As shown in Figure 7 A vehicle door system control method comprises the following steps:

[0105] The driver A of the first conversion device is controlled to open, and the driver B is controlled to be locked, and the front door is opened by the electric scissor door opening mode;

[0106] At this time, the driver D of the second conversion device is controlled to be locked, and the driver C is controlled to open, and the rear door is opened by the electric swing door opening mode.
