Description

Technical Field

[0001] The invention belongs to the technical field of automobile manufacturing, and in particular relates to a door system, an automobile and a control method. Background Art

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

[0003] For ordinary consumers:

[0004] If there are young infants in the family, they often need an adult to hold the infant or to help the infant get into the vehicle and sit down. In this process, the opening space of traditional car doors often cannot meet the needs of an adult entering the vehicle and bringing an infant with him or her, resulting in crowded space or a lack of effective support points for the upper body when the person steps into the vehicle with one leg.

[0005] If there are elderly people with limited mobility in the family, they often move slowly and need auxiliary tools to walk steadily, such as crutches. When the elderly get on and off the car, in order to achieve body balance, one hand needs to hold the crutches, and the other hand needs to use another support point to better achieve the action of getting on and off the car. Usually, the other support point is the vehicle body or door frame. However, the rear door of a traditional vehicle adopts a flat door design. After the door is opened, the rear door rotates to a position close to the front of the car. There is a lack of support points near the rear of the car, which cannot provide a support point for the elderly with limited mobility to balance their bodies.

[0006] If there is a person in the family who suffers from hemiplegia of the lower limbs or loses motor function of the lower limbs due to illness, multiple people will be needed to move him or her when getting on or off the vehicle. At this time, in order to ensure the convenience of getting on or off the vehicle, it is often necessary to move the front seats forward and rotate the traditional doors to the maximum open position. Even so, due to the influence of the opening and closing position of the traditional swing doors, the convenience of such people getting on and off the vehicle cannot be guaranteed.

[0007] In addition, although there are some specially designed doors on the market, such as scissor doors or gull-wing doors, these designs are often only used in high-end or special-purpose vehicles, and usually require complex mechanical structures to achieve, which not only increases manufacturing costs, but may also make maintenance more difficult. Summary of the invention

[0008] In order to overcome the deficiencies of the above-mentioned prior art, the present invention provides a door system, a vehicle and a control method. The opening methods of the front door include an electric scissor door opening method and an electric swing door opening method, and the opening methods of the rear door include an electric double-door opening method and an electric swing door opening method. The actual demands of users are comprehensively considered to meet the needs of different customer groups, so that the user's driving experience and the safety of getting on and off the vehicle are significantly improved.

[0056] Embodiment 1

[0057] As described in the above background technology, although traditional opening methods, such as hinged doors or sliding doors, meet the basic usage needs of users, they have certain limitations in providing spacious entry and exit space and improving user experience.

[0058] If there are young infants in the family, they often need an adult to hold the infant or to help the infant get into the vehicle and sit down. In this process, the opening space of traditional car doors often cannot meet the needs of an adult entering the vehicle and bringing an infant with him or her, resulting in crowded space or a lack of effective support points for the upper body when the person steps into the vehicle with one leg.

[0059] If there are elderly people with limited mobility in the family, they often move slowly and need auxiliary tools to walk steadily, such as crutches. When the elderly get on and off the car, in order to achieve body balance, one hand needs to hold the crutches, and the other hand needs to use another support point to better achieve the action of getting on and off the car. Usually, the other support point is the vehicle body or door frame. However, the rear door of a traditional vehicle adopts a flat door design. After the door is opened, the rear door rotates to a position close to the front of the car. There is a lack of support points near the rear of the car, which cannot provide a support point for the elderly with limited mobility to balance their bodies.

[0060] If there is a person in the family who suffers from hemiplegia of the lower limbs or loses motor function of the lower limbs due to illness, multiple people will be needed to move him or her when getting on or off the vehicle. At this time, in order to ensure the convenience of getting on or off the vehicle, it is often necessary to move the front seats forward and rotate the traditional doors to the maximum open position. Even so, due to the influence of the opening and closing position of the traditional swing doors, the convenience of such people getting on and off the vehicle cannot be guaranteed.

[0061] In summary, the existing door systems still have some shortcomings in terms of space experience and safety for different types of users getting on and off the vehicle.

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

[0063] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, a vehicle door system comprises a front door and a rear door, wherein 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 is connected to the vehicle body via 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 via a second conversion device, and the second conversion device is used to convert the opening mode of the rear door between an electric double-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 rotationally 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 rotationally connected to the vehicle body via a rotation connection device.

[0068] like Figure 1 As shown in the figure, the front door of this embodiment is opened in an electric swing door mode and the rear door is opened in an electric swing door mode. When the front door and the rear door are opened, the space for the entire vehicle to accommodate users getting on and off the vehicle is greatly improved compared with the traditional mode, and the rear door moved to the rear side of the vehicle body can also provide an effective support point for people getting on and off the vehicle. At this time, whether it is people carrying infants and young children, elderly people with mobility difficulties, or people with lower limb mobility disabilities, they can all achieve maximum safety and convenience when getting on and off the vehicle.

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

[0070] like Figure 2 As shown, the front door of this embodiment is opened in an electric swing door mode + the rear door is opened in an electric double door mode. Compared with the above Figure 1 Since the rear door is in an outward extended state, it can provide an effective outward extending support point for people getting on and off the vehicle, which is especially suitable for elderly people with limited mobility. It can also provide anti-tipping protection for people carrying infants and young children on and off the vehicle, thereby improving the overall safety and convenience when getting on and off the vehicle.

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

[0072] like Figure 3 As shown in the figure, the front door of this embodiment is opened by an electric scissor door + the rear door is opened by an electric swing door. In this way, after the doors are opened, the front seats can be moved forward and the rear seats can be moved backward, making it easier for people with lower limb motor disabilities to get on and off the vehicle, and providing as much lower space as possible for such people. Figure 1 and Figure 2In the event of a traffic accident, the front door is opened by rotating diagonally upwards, thus providing a larger lower accommodation space, making it easier for people with lower limb disabilities or lower limb movement difficulties to get 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 schematic diagram, a top view, a front view, and a side view when the front door is opened in an electric scissor door mode and the rear door is opened in an electric swing door mode.

[0074] like Figure 4 As shown, the front door of this embodiment is an electric scissor door opening method + a rear door electric double door opening method. After the rear door is opened in this way, it can also provide an effective support point extending to the outside and can provide a larger 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 schematic diagram, a top view, a front view, and a side view when the front door is opened in an electric scissor door mode and the rear door is opened in an electric double-door mode.

[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 opening mode, and the driver B is used to control the opening or locking of the electric swing door opening mode.

[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. In order to enable the first conversion device to realize the conversion of the front door opening mode between the electric scissor door opening mode and the electric swing door opening mode, two drivers, namely driver A and driver B, are provided in this embodiment. When driver A is turned on and driver B is locked, the vehicle door will be controlled to open in the electric scissor door opening mode; conversely, when driver A is locked and driver B is turned on, the vehicle door will be controlled to open in the electric swing door opening mode.

[0078] More specifically, Figure 5As shown, the first conversion device of this embodiment can adopt the existing technology, such as the Chinese invention patent application with a publication date of 2024.05.07, publication number of CN 117988650 A, and applicant Chery Automobile Co., Ltd., which discloses a door opening and closing device, a vehicle and a vehicle control method, wherein in the door opening and closing device, the first door member 2 is rotatably connected to the body member 1, the second door member 3 is connected to the first door member 2, and one end of the scissor door driving member 4 is connected to the body and the other end is connected to the first door member 2. One end of the swing door driving member 5 is connected to the first door member 2, and the other end is connected to the second door member 3.

[0079] The switching member 6 is arranged on the second door member 3, and is used to control the first door member 2 and the second door member 3 to switch between a rigid connection and a rotational connection, so that the door opening and closing device switches between a scissor door mode and a 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 driving 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 rotationally connected, and the swing door driving 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 the driver B of the first conversion device in this embodiment; the vehicle 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 above patent will not be elaborated 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 FIG. 2 is a schematic diagram of the second conversion device of the rear door of this embodiment, wherein 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 .

[0085] In order to enable the second conversion device to convert the rear door opening mode between the electric split door opening mode and the electric swing door opening mode, the second conversion device of this embodiment is provided with two drivers, namely, driver C11 and driver D8. When driver D8 is turned on and driver C11 is locked, the vehicle door is controlled to be opened in the electric split door opening mode; conversely, when driver D8 is locked and driver C11 is turned on, the vehicle door is controlled to be opened in the electric swing door opening mode.

[0086] The specific positional relationship and connection relationship of the second conversion device are as follows:

[0087] like Figure 6 As shown, the first hinge 7 is connected to the vehicle door through the first hinge fixing page 9, and the driver D8 is connected to the first hinge 7. The driver D8 is used to drive the first hinge 7 to move. The first hinge 7 is used to drive the vehicle door to rotate relative to the vehicle body under the drive of the driver D8.

[0088] When the driver D8 is turned on, the first hinge 7 will be driven to change its displacement, and the first hinge 7 will drive the door to rotate relative to the body, ultimately achieving the effect of the rear door opening like an electric double door.

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

[0090] In this way, when the driver C11 is turned on, the second hinge 12 will be driven to change its displacement, and the second hinge 12 will push the door to move backward relative to the vehicle body, and finally the rear door will be opened like a swing door.

[0091] It can be understood that a vehicle body side mounting panel 10 is provided on the vehicle body, and the driver C11 is connected to the vehicle body through the vehicle body side mounting panel 10 .

[0092] In this embodiment, the first hinge 7 and the second hinge 12 are used as transmission devices, and both can adopt existing technologies, as long as the displacement of the first hinge 7 and the second hinge 12 can enable the door to be opened in a corresponding manner. This embodiment does not impose any limitation on this.

[0093] In some embodiments, the front door includes a left front door and a right front door, the rear door includes a left rear door and a right rear door, the left front door and the right front door are symmetrically arranged, and the left and right doors and the right rear door are symmetrically arranged.

[0094] In some embodiments, a controller is also included, which 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 through a first conversion device, and is also used to convert the opening mode of the rear door between an electric double door opening mode and an electric swing door opening mode through a second conversion device.

[0095] In some embodiments, the controller is also used to control the opening modes of the left front door and the right front door to be consistent through the first conversion device, and to control the opening modes of the left rear door and the right rear door to be consistent through the second conversion device.

[0096] In some embodiments:

[0097] The controller is also used to control the opening mode of the rear door to be an electric swing door opening mode through the second conversion device when the opening mode of the front door is controlled to be an electric scissor door opening mode through the first conversion device;

[0098] The controller is also used to control the opening mode of the rear door to be an electric double-door opening mode through the second conversion device when the opening mode of the front door is controlled to be an electric swing door opening mode through the first conversion device.
