Technical Field
[0001] The invention relates to the technical field of door control, in particular to a split tailgate control system and a car. Background Art
[0002] The rear of a car is usually equipped with a trunk, which can be used to store luggage, spare wheels and other items. The trunk door is referred to as the "tailgate". The opening method of the tailgate needs to be designed according to the positioning of the vehicle model. Generally speaking, the tailgate is opened from bottom to top; but in order to make the trunk fully open, the existing car tailgate can also be designed into two parts that can be opened in sections, namely the "sky door" and the "ground door", and the opening and closing of the sky door and the ground door are controlled by a control unit.
[0003] However, the sky door and / or ground door of existing cars may not be able to open automatically or may not be closed properly when interfered by external factors. It is usually necessary to reset the sky door and the ground door and then close them again, or detect and collect the positions of the sky door and the ground door through a control unit, and readjust the operating strategy between the sky door and the ground door through position information sharing and interaction between the sky door and the ground door control units, so as to achieve the closing of the sky door and the ground door. However, the above operations and processes are relatively cumbersome, and the sky door and the ground door cannot be quickly closed in the closed position, resulting in a poor user experience for car owners or passengers. Summary of the invention

DETAILED DESCRIPTION
[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.
[0021] Example 1 See also Figure 1-2, this embodiment discloses a split tailgate control system, including a first door 1, a second door 2, an identification point 13, a first control unit 7 and a second control unit 8. The first door 1 is movably arranged between an open door position and a closed door position of the vehicle body in an articulated manner; the second door 2 is movably arranged between an open door position and a closed door position of the vehicle body in an articulated manner. The identification point 13 is a certain calibrated position point in the running track of the first door 1; the first control unit 7 is electrically connected to the first door 1, and is used to control the opening and closing of the first door 1 and identify the position area of the first door 1 in the running track, and at the same time, the relevant signal of the second door lock 6 is identified based on the position area of the first door 1, and the second control unit 8 is electrically connected to the second door 2, and is used to control the opening and closing of the second door 2.
[0022] When the first door 1 reaches the identification point 13, without the need to share or interact with the first control unit 7 and the second control unit 8 about the position information of the first door 1 and the second door 2, the first control unit 7 controls the first door 1 to perform corresponding opening, closing or parking actions based on the signal feedback from the second door lock 6, thereby realizing the opening and closing operations of the first door 1 and the second door 2 under normal and abnormal conditions.
[0023] Among them, the position of the identification point 13 on the running track of the first door 1 is not fixed, and can be customized through calibration according to actual application conditions, as long as it can meet the conditions for normal opening and closing of the first door 1 and the second door 2.
[0024] In this embodiment, the function of the identification point 13 is to refer to Figure 3 Under normal circumstances, when the user closes the first door 1 and the second door 2, when the first door 1 moves to the identification point 13, if the first control unit 7 recognizes the relevant signal of the second door lock 6 at the identification point 13, the first door 1 will move normally to the door closing position and automatically complete the locking at the door closing position. Figure 4 When the first door 1 reaches the identification point 13, if the first control unit 7 cannot identify the relevant signal of the second door lock 6 at the identification point 13, that is, the second door 2 is not closed normally, the first door 1 will be parked, and if the first control unit 7 still cannot identify the relevant signal of the second door lock 6 within the preset time (customizable), the first control unit 7 controls the first door 1 to keep stopping or running in reverse.
[0025] In order to solve the problem that the tailgate in the prior art cannot be closed normally, the present embodiment provides a new tailgate control system, which cleverly sets a certain calibrated position point in the running trajectory of the first door 1 as the identification point 13. If the first door 1 runs to the identification point 13, it will stop, and based on the position area of the first door 1, the position between the first door 1 and the identification point 13 is identified by the first control unit 7, and the relevant signal of the second door lock 6 is identified to ensure that the second door 2 and the first door 1 can be opened and closed normally, especially to ensure that the second door 2 and the first door 1 are closed in place, without the need to share and interact with the position of the first door 1 and the second door 2, thereby simplifying the control logic, and making the operation simple and convenient, and without the need to reset the position of the second door 2 and the first door 1 and then close.
[0026] In this embodiment, a first rotating shaft is provided at the upper part of the vehicle body, and the first door 1 is hinged to the first rotating shaft and rotates around the first rotating shaft to open and close; a second rotating shaft is provided at the lower part of the vehicle body, and the second door 2 is hinged to the second rotating shaft and rotates around the second rotating shaft to open and close.
[0027] See also Figure 1-2 The split tailgate control system includes a first driving device 3 electrically connected to a first control unit 7, the first driving device 3 is connected between the vehicle body and the first door 1, and is used to drive the first door 1 to open, close or stop. The split tailgate control system includes a second driving device 4 electrically connected to a second control unit 8, the second driving device 4 is connected between the vehicle body and the second door 2, and is used to drive the second door 2 to open, close or stop. In this embodiment, the first driving device 3 and the second driving device 4 both use electric struts, which are more convenient and flexible to drive.
[0028] The split tailgate control system includes a first switch 10, a second switch 11 and a third switch 12. The first switch 10 is electrically connected to the first control unit 7, and is used to control the start and pause of the first drive device 3 to open and close the first door 1. The second switch 11 is electrically connected to the second control unit 8, and is used to control the start and pause of the second drive device 4 to open and close the second door 2. The third switch 12 is electrically connected to the first control unit 7 and the second control unit 8, respectively, and the third switch 12 serves as a master switch, and is used to control the start and pause of the first drive device 3 and the second drive device 4 at the same time.
[0029] See also Figure 2 The split tailgate control system includes another control unit 9 electrically connected to the second switch 11. The other control unit 9 can be used to identify the position area of the first vehicle door 1 in the running track like the first control unit 7.
[0030] Under normal circumstances, when the user uses the third switch 12 to close the first door 1 and the second door 2, the first door 1 and the second door 2 are closed in a certain order or are closed simultaneously and at different speeds. When the first door 1 reaches the identification point 13, the first control unit 7 will identify the signal of the second door lock 6.
[0031] Example 2 See also Figure 5 When the second door 2 is fully closed, the first door 1 can be closed only by the first switch 10, that is, at this time the first control unit 7 can recognize the corresponding signal of the second door lock 6, and no matter what position the first door 1 is in, the first control unit 7 can control the first door 1 to close normally.
[0032] Example 3 See also Figure 6 When the first door 1 is in the area between the identification point 13 and the door opening position, for example, when the first door 1 is opened to the opening required by the user and the user pauses and continues to open the first door 1; or when the user directly manually closes the first door 1 to this area; or when the first door 1 stops in this area due to external obstacles and other factors, the second door 2 can be closed only by the second switch 11; that is, if the first control unit 7 or other control unit 9 recognizes that the first door 1 is in the area between the identification point 13 and the door opening position, the second door 2 can be normally controlled to be completely closed through the second switch 11, and after the second door 2 is completely closed, the first control unit 7 can control the first door 1 to be normally closed.
[0033] Example 4 The role of the identification point is also that in the event of an abnormality, that is, when the first door 1 and the second door 2 cannot be opened and closed normally, based on the position area of the first door 1, the first control unit 7 or other control unit 9 determines whether to block the functional use of the second switch 11.
[0034] In the event of an abnormality, such as the second door 2 not being completely closed, refer to Figure 7 If the first door 1 is located in the area between the identification point 13 and the door opening position, the first switch 10 is used to close the first door 1, and the second door 2 will run to the identification point 13 and stop because the first control unit 7 cannot recognize the corresponding signal of the second door lock 6; if the first control unit 7 cannot recognize the signal change of the second door lock 6 within a certain period of time (customizable), the first drive device 3 is controlled to remain in a stopped state or run in reverse.
[0035] Example 5 See also Figure 8In the event of the same abnormality, when the first door 1 is in the area between the identification point 13 and the door closing position, if the first control unit 7 cannot identify the relevant signal of the second door lock 6, the first door 1 will not operate; if the first control unit 7 still cannot identify the signal change of the second door lock 6 within a certain period of time (customizable), the first drive device 3 is controlled to remain in a stopped state or run in reverse, that is, the first door 1 remains in a stopped state or runs in reverse.
[0036] See also Figure 8 In the case of the same abnormality, when the first control unit 7 or other control unit 9 recognizes that the first door 1 is at any position between the recognition point 13 and the door closing position due to external factors or other factors, the first control unit 7 or other control unit 9 will block the function of the second switch 11. At this time, the second door 2 cannot be controlled to operate electrically by using the second switch 11. If you want to close the first door 1 and the second door 2, you can manually adjust the positions of the first door 1 and the second door 2 to the following positions: Figure 3 , Figure 6 and Figure 7 Position as shown and press the Figure 3 , Figure 6 and Figure 7 The related operations shown are to close the first door 1 and the second door 2. At this time, you can also manually close the second door 2 and then use the first switch to electrically close the first door 1; or directly manually close the first door 1 and the second door 2.
[0037] The area between the identification point 13 and the door opening position does not include the position of the identification point 13 but includes the door opening position; the area between the identification point 13 and the door closing position includes the position of the identification point 13 and the door closing position.
[0038] It can be understood that in any of the above situations, if the user uses the third switch 12 for control, since the third switch 12 also controls the operation of the first door 1 and the second door 2 respectively through the first control unit 7 and the second control unit 8, the results are consistent with the corresponding situations mentioned above.
[0039] The working principle of the split tailgate control system of the present invention is: when the user uses the third switch 12 to close the first door 1 and the second door 2, the first door 1 and the second door 2 are closed in a sequence of first and second or are operated simultaneously and closed at different speeds. If the first control unit 7 recognizes the relevant signal of the second door lock 6, the first door 1 is operated normally to the door closing position, and the second door 2 is also operated normally to the door closing position; when the first door 1 reaches the closed position, the first door lock 5 locks and tightens the first door 1; at the same time, the second door lock 6 also locks and tightens the second door 2 when the second door 2 reaches the door closing position; when the first door 1 is ready to be opened, the first door lock 5 unlocks and releases the first door 1, and when the second door 2 is ready to be opened, the second door lock 6 unlocks and releases the second door 2.
[0040] Example 6 This embodiment discloses a car, which can realize normal opening and closing of the second door 2 and the first door 1 when disturbed by external factors or encountering abnormal situations, thereby improving customer experience. The car includes the split tailgate control system.
[0041] In summary, the present invention not only ensures that the second door 2 and the first door 1 can be opened and closed normally by cleverly setting the identification point 13; but also, when an electronic failure occurs, the first door 1 and the second door 2 can be manually closed to improve the safety of door use, realize the switching between automatic and semi-automatic functions of the doors, simplify the control logic, eliminate the need for interaction and sharing between door positions, and solve the problem that the existing car top doors and ground doors cannot be quickly closed.
[0042] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
