Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0045] It should be noted that when a component is said to be "fixed to" another component, it can be directly on the other component or there can be a central component. When a component is said to be "connected to" another component, it can be directly connected to the other component or there can be a central component at the same time.

[0046] Unless otherwise defined, all technical and scientific terms used in this application have the same meaning as those commonly understood by those skilled in the art to which this application belongs. The terms used in this application and in the specification are only for the purpose of describing specific embodiments and are not intended to limit this application. The term "and / or" used in this application includes any and all combinations of one or more of the related listed items.

[0047] In conjunction with the accompanying drawings, some embodiments of the present application are described in detail below. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other.

[0048] The present application proposes a vehicle, which can be an electric vehicle, a fuel vehicle, or a hybrid vehicle. The vehicle can be a sedan, an off-road vehicle, or a truck, and the present application does not limit this.

[0049] Please refer to Figure 1 and Figure 2 The vehicle 1000 includes a vehicle body 200 and an electric back door 100. The vehicle body 200 of the vehicle 1000 serves as a supporting frame of the vehicle 1000 and is used to support and connect various component assemblies of the vehicle 1000. The vehicle body 200 is formed with a backup space 210. The backup space 210 has an opening, and the user's items can be stored in the backup space 210 through the opening. The electric back door 100 is rotatably arranged on the vehicle body 200. The electric back door 100 has an open state and a closed state. When the electric back door 100 is in the closed state, the electric back door 100 closes the opening of the backup space 210, thereby protecting the safety of the sealed items in the backup space 210. When the electric back door 100 is in the open state, the opening of the backup space 210 is revealed, so that it is convenient for the user to store or take out the items in the backup space 210.

[0050] In the present application, the electric back door 100 is a split back door, and the electric back door 100 includes a first back door 1 (also commonly known as a top door) and a second back door 2 (also commonly known as a bottom door). The first end of the first back door 1 is rotatably connected to the upper wall surface of the opening of the backup space 210 through a first hinge shaft 3, and the first end of the second back door 2 is rotatably connected to the lower wall surface of the opening of the backup space 210 through a second hinge shaft 4. It can be understood that in order to drive the first back door 1 and the second back door 2 to move, in some other possible implementations of the present application, the electric back door 100 may also include a first drive assembly 10 and a second drive assembly 20, and the first drive assembly 10 and the second drive assembly 20 may be motors, pneumatic cylinders, or hydraulic cylinders, and the present application does not limit this.

[0051] The first driving assembly 10 is connected to the first back door 1 to drive the second end of the first back door 1 to rotate around the first hinge shaft 3 .

[0052] The second driving assembly 20 is connected to the second back door 2 to drive the second end of the second back door 2 to rotate around the second hinge shaft 4 .

[0053] When the electric back door 100 is opened, the second end of the first back door 1 contacts the second end of the second back door 2, thereby jointly closing the opening of the trunk space 210. Unlike the conventional electric back door 100 which has only one opening state, the electric back door 100 of the present application has a first opening state and a second opening state.

[0054] Please refer to Figure 2 When the electric back door 100 is in the first opening state, the first back door 1 is opened and the second back door 2 is closed. At this time, the upper half of the opening of the trunk space 210 is exposed. In this state, the user can store or take out items in the trunk space 210 through the upper half of the opening, and the second back door 2 shielded at the lower half of the opening can prevent the items in the trunk space 210 from being completely exposed to the outside field of vision, thereby improving the privacy of the vehicle 1000.

[0055] Please refer to Figure 1 When the electric back door 100 is in the second opening state, the first back door 1 and the second back door 2 are opened at the same time, and the opening of the trunk space 210 is fully exposed. In this way, it is convenient for the user to store and take out large items in the trunk space 210.

[0056] The electric back door 100 further includes a second button 8 and a third button 9, which are arranged on the first back door 1. When the second button 8 is pressed, the first back door 1 is opened. When the third button is pressed, the first back door 1 is closed.

[0057] The electric tailgate 100 also includes a first locking structure 5, which includes a first lock ring 51 and a first lock body 52. ​​The first lock ring 51 is arranged at the second end of the first tailgate 1, and the first lock body 52 is arranged at the second end of the second tailgate 2. When the electric tailgate 100 is closed, the second end of the first tailgate 1 contacts the second end of the second tailgate 2, and the lock tongue of the first lock body 52 extends into the first lock ring 51, thereby realizing the locking of the first tailgate 1 and the second tailgate 2.

[0058] The electric tailgate 100 also includes a second locking structure 6, which includes a second lock ring 61 and a second lock body 62. The second lock ring 61 is arranged on both sides of the second tailgate 2, and the second lock body 62 is arranged on the cavity wall of the backup space 210. When the second tailgate 2 is in a closed state, the second tailgate 2 contacts the cavity wall of the backup space 210, and the lock tongue of the second lock body 62 extends into the second lock ring 61, thereby realizing the locking of the second tailgate 2.

[0059] The first back door 1 and the second back door 2 are both opened toward the outside of the trunk space 210, and in order to achieve the locking of the first back door 1 and the second back door 2, the first back door 1 and the second back door 2 overlap in space. This also means that the opening sequence of the electric back door 100 must be to open the first back door 1 first, and then open the second back door 2 after the first back door 1 is opened to a certain position, so as to avoid the collision between the first back door 1 and the second back door 2 and protect the safety of the vehicle 1000.

[0060] In order to avoid the collision between the first back door 1 and the second back door 2, the relevant technology will set a position sensor on the vehicle body 200. The position sensor is generally a Hall sensor. The Hall sensor includes a Hall element and a magnet. The magnet is set on the first back door 1 and the second back door 2. A current is passed through the Hall element, and the current is used to generate a voltage difference between the Hall element and the magnet. The voltage difference is also called the Hall voltage. When the first back door 1 and the second back door 2 are closed, the distance between the magnet and the Hall element is fixed, and the magnetic field strength formed by the magnet is also constant. At this time, the voltage difference between the Hall element and the magnet remains constant. When the position of the first back door 1 and the second back door 2 changes, the distance between the magnet and the Hall element will change, and this change will cause the magnetic field strength to change accordingly. The change in magnetic field strength will cause the voltage value output by the Hall element to change. By detecting the change in this voltage value, the distance between the first back door 1 and the second back door 2 and the vehicle body 200 can be determined, thereby determining the opening position of the first back door 1 and the second back door 2.

[0061] However, due to the reliability of electronic components, there is a possibility of data loss when the position sensor detects the positions of the first back door 1 and the second back door 2. Once the position sensor loses data, there is a risk of collision between the first back door 1 and the second back door 2.

[0062] To solve the above problems, in the present application, the electric back door 100 further includes a first button 7, which is used to control the opening and closing of the second back door 2. When the first button 7 is pressed, the second back door 2 is opened. When the first button 7 is pressed here, the second back door 2 is closed. The first button 7 is arranged in the backup space 210. When the first back door 1 is closed, the first back door 1 and the second back door 2 jointly close the opening of the backup space 210 and cover the first button 7. When the first back door 1 is opened, the first back door 1 is separated from the second back door 2, and the first button 7 is presented in the user's field of vision through the opening and can be touched by the user.

[0063] The technical solution of the present application cancels the position information interaction between the first back door 1 and the second back door 2, and instead sets the first button 7 for opening the second back door 2 in the backup space 210, so that the user must open the first back door 1 before pressing the first button 7 to open the second back door 2. In this way, the collision risk between the first back door 1 and the second back door 2 is reduced without affecting the normal use of the electric back door 100 by the user.

[0064] The first button 7 can be set at any position of the backup space 210. In one possible implementation of the present application, the first button 7 is set on the side wall of the backup space 210. There is a certain height between the first button 7 and the bottom of the backup space 210. The first back door 1 needs to be opened to a certain angle before the first button 7 can be presented to the user. In this way, it is prevented that the first button 7 is pressed in advance, causing the second back door 2 to collide with the first back door 1. Further, in another possible implementation of the present application, the height of the backup space 210 in the vertical direction is A, and the height of the first button 7 from the bottom wall of the backup space 210 is B, 0.5≤B / A≤1. That is, the first button 7 is set at more than half of the height of the backup space 210, so as to further prevent the first button 7 from being pressed in advance and improve the reliability of the operation of the electric back door 100.

[0065] Please refer to Figure 3 The vehicle also includes a control device 300 for an electric back door, and the control device 300 for the electric back door includes a controller 1001, a communication bus 1002, a user interface 1003, a network interface 1004, and a memory 1005. The communication bus 1002 is used to realize the connection and communication between these components. The user interface 1003 is mainly used for users to interact with data. The user interface 1003 may include a display screen (Display), an input unit such as a keyboard (Keyboard), and the user interface 1003 may also include a standard wired interface and a wireless interface. The network interface 1004 is mainly used for data communication with a network server. The network interface 1004 may optionally include a standard wired interface and a wireless interface (such as a wireless fidelity (Wi reless-Fidel ity, Wi-Fi) interface).

[0066] The controller 1001 is used to call computer instructions to execute the control method of the electric back door. The controller 1001 can be a central processing unit (CPU), or other general controllers, digital signal controllers (DSP), application specific integrated circuits (ASIC), field-programmable gate arrays (FPGA), or other programmable logic devices, discrete gates or transistor logic devices, discrete hardware components, etc.

[0067] In one implementation manner of the present application, the controller 1001 includes a first controller and a second controller, the first controller is used to control the opening and closing of the first back door, and the second controller is used to control the opening and closing of the second back door.

[0068] The memory 1005 is used to store computer instructions. The memory 1005 is used to store an operating system, a network communication module, a user interface module, and a control program for an electric back door. The memory 1005 may be a volatile memory or a non-volatile memory, or may include both volatile and non-volatile memories. Among them, the non-volatile memory may be a read-only memory (ROM), a programmable read-only memory (PROM), an erasable programmable read-only memory (EPROM), an electrically erasable programmable read-only memory (EEPROM), or a flash memory. The volatile memory may be a random access memory (RAM), which is used as an external cache. By way of example but not limitation, many forms of RAM are available, such as static random access memory (SRAM), dynamic random access memory (DRAM), synchronous dynamic random access memory (SDRAM), double data rate synchronous dynamic random access memory (DDR SDRAM), enhanced synchronous dynamic random access memory (ESDRAM), synchronous link dynamic random access memory (SLDRAM) and direct memory bus random access memory (Direct Rambus RAM, DR RAM).

[0069] It should be noted that when the controller 1001 is a general controller, DSP, ASIC, FPGA or other programmable logic device, discrete gate or transistor logic device, discrete hardware component, the memory (storage module) is integrated in the controller.

[0070] It should be noted that the memory described herein is intended to include, but is not limited to, these and any other suitable types of memory.

[0071] In addition to the data bus, the bus may also include a power bus, a control bus, a status signal bus, etc. However, for the sake of clarity, various buses are marked as buses in the figure.

[0072] The vehicle further includes a storage medium on which a control program for the electric back door is stored. The control program for the electric back door is executed by the controller to implement a control method for the electric back door.

[0073] Please refer to Figure 4 , Figure 4 This is a flow chart of a first embodiment of a method for controlling an electric back door provided in the present application. In this embodiment, the method for controlling an electric back door includes:

[0074] S101: When a first signal transmitted by a first button is received, the second back door is opened.

[0075] In this embodiment, the second controller for controlling the second back door no longer receives the position information of the first back door, but only receives and processes the first signal transmitted from the first button to open the second back door. Since the first button is hidden behind the first back door, the user must open the first back door before opening the second back door, thereby improving the reliability of the electric back door.

[0076] In order to improve the reliability of opening the second back door, in one possible implementation mode of the present application, before opening the second back door, the following steps are further included:

[0077] If the vehicle is in motion, the second tailgate will not be opened.

[0078] In this embodiment, when the second controller receives the first signal and is ready to open the second back door, it will detect the movement state of the vehicle. The second back door will only be opened when the vehicle is in a parking state (i.e., the vehicle movement speed is 0). In this way, the second back door is prevented from being opened during the driving process of the vehicle, thereby improving driving safety.

[0079] There are many ways to detect the vehicle's motion status. The second controller can determine the vehicle's driving status through the vehicle's gear position, or through the vehicle's driving speed, or through the rotation of the vehicle's wheels. This application does not impose any restrictions on this.

[0080] Please refer to Figure 5 , Figure 5 This is a flow chart of a second embodiment of the control method of the electric back door provided in the present application. In this embodiment, the control method of the electric back door includes:

[0081] S201: When a second signal is received, the first back door is opened to reveal a first button.

[0082] There are many ways to send the second signal. The second signal can be sent by the user operating the vehicle's control panel, by the user through voice, or by the user pressing the second button on the first back door. This application does not impose any restrictions on this.

[0083] In order to improve the reliability of opening the first back door, in one possible implementation manner of the present application, before opening the first back door, the following steps are further included:

[0084] If the vehicle is in driving state, the first tailgate will not be opened.

[0085] In this embodiment, when the first controller receives the first signal and is ready to open the first back door, it will detect the movement state of the vehicle. The first back door will be opened only when the vehicle is in a parking state (i.e., the vehicle movement speed is 0). In this way, the first back door is prevented from being opened during the driving process of the vehicle, thereby improving driving safety.

[0086] There are many ways to detect the vehicle's motion status. The first controller can determine the vehicle's driving status through the vehicle's gear position, or through the vehicle's driving speed, or through the rotation of the vehicle's wheels. This application does not impose any restrictions on this.

[0087] S202: When a first signal transmitted by a first button is received, the second back door is opened.

[0088] S203: When a third signal transmitted by the first button is received, close the second back door.

[0089] S204: When the fourth signal is received and the second tailgate is in a locked state, close the first tailgate.

[0090] There are many ways to send the fourth signal. The second signal can be sent by the user operating the vehicle's control panel, or by the user through voice, or by the user pressing the third button on the first back door. This application does not impose any restrictions on this.

[0091] In this embodiment, the second back door cannot be opened directly, but can only be opened after the user issues a start command to the first back door (sends a second signal). When the first controller receives the first signal sent by the user, the controller will control the first back door to open to reveal the first button. After the first back door is opened, if the user needs a larger opening space to store or access items in the backup space, the first button will be pressed. When the user presses the first button, the second back door opens. When the user has finished accessing the items in the backup space, the user presses the first button here and sends a third signal to control the second back door to close. Similar to the opening, the second controller will only recognize the third signal sent by the first button, so as to ensure the reliability of the closing of the second back door.

[0092] When the second back door is closed, the user can send a fourth signal to the first controller by pressing the third button or in other ways. After receiving the fourth signal, the first controller will control the first back door to close. In order to ensure that the first back door does not collide with the second back door during the closing process, before closing the first back door, the first controller will detect the locking state of the second back door. Only when the second back door is completely locked will the first controller execute the closing action of the first back door. In this way, the reliability of the first back door during the closing process is improved.

[0093] There are many ways to obtain the locking state of the second back door. The first controller can obtain the locking state of the second lock body through a sensor disposed in the second lock body. The first controller can also obtain the locking state of the second back door through a full lock signal transmitted by the second controller.

[0094] Hereinafter, the opening method and closing method of the electric back door of the present application will be described in detail in conjunction with the logic diagram.

[0095] Please refer to Figure 6 The method for opening the electric back door provided in the present application comprises the following steps:

[0096] S011. The first controller receives a second signal.

[0097] S012. The first controller determines whether the vehicle is in a driving state. If not, the process proceeds to S013. If so, no action is performed.

[0098] S013. The first controller controls the first lock body to separate from the first lock ring and supplies power to the first drive assembly.

[0099] S014. The first controller controls the first driving assembly to drive the first back door to move in a direction away from the backup space until the first back door reaches a preset soft stop position.

[0100] S015. The second controller receives the first signal.

[0101] S016. The second controller determines whether the vehicle is in a driving state. If not, it goes to S017. If so, no action is performed.

[0102] S017. The second controller controls the second lock body to separate from the second lock ring and supplies power to the second drive assembly.

[0103] S018. The second controller controls the second driving assembly to drive the second back door to move away from the backup space until the second back door reaches a preset soft stop position.

[0104] Please refer to Figure 7 The method for closing the electric back door provided in the present application comprises the following steps:

[0105] S021. The second controller receives a third signal.

[0106] S022. The second controller supplies power to the second driving assembly, and controls the second driving assembly to control the second back door to move toward the backup space.

[0107] S023. During the closing process of the second back door, the second controller continuously detects the half-lock signal transmitted from the second locking structure. If the half-lock signal transmitted from the second locking structure is received, the process proceeds to S024; otherwise, the process returns to S022.

[0108] S024: The second controller controls the second driving assembly to stop driving, and controls the second locking structure to perform an attraction action until the second back door is locked.

[0109] S025. The second controller sends a full-lock signal to the first controller.

[0110] S026. The first controller receives a fourth signal.
