Description

Technical Field

[0001] The present invention relates to the field of vehicle equipment, and more particularly to a split door system and a vehicle. Background Art

[0002] Generally, a split door is provided on the vehicle body for opening or closing at least part of the opening of the vehicle body. In related technologies, two driving mechanisms are usually used to control the first door and the second door respectively. The Hall signals of the driving mechanism for driving the first door and the driving mechanism for driving the second door, as well as the corresponding control unit, are used to obtain the position information of the first door and the second door. After the position information of the first door and the second door is exchanged, the control unit issues instructions to the corresponding driving mechanisms to control the movement of the first door and the second door. This results in a relatively complex control logic for the first door and the second door. Therefore, there is a need to solve this problem. Summary of the Invention

[0072] The embodiments of the present invention will be described in detail below. The examples of the embodiments are shown in the drawings, where the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below by referring to the drawings are exemplary and are only used to explain the present invention and should not be construed as limiting the present invention.

[0073] Below, refer toFigures 1-7 Describe the split door system 1a according to an embodiment of the present invention.

[0074] Refer to Figures 1-4 , the split door system 1a according to an embodiment of the first aspect of the present invention includes a first door 11, a second door 21, a first door lock, a second door lock, a first driver 13, a second driver 23, a first sensor 32, a second sensor, a first control unit 31 and a second control unit 33. Both the first door 11 and the second door 21 are adapted to be rotatably connected to the vehicle body. For example, during the movement of the door to the open position, the first door 11 and the second door 21 move away from each other, and during the movement of the door to the closed position, the first door 11 and the second door 21 move closer to each other.

[0075] The first door lock is used to cooperate with the first door 11, and a first door lock sensor is arranged on the first door lock. The first door lock sensor is used to collect and send a first door lock status signal, and the first door lock status signal includes a first closing signal and a first release signal. The second door lock is used to cooperate with the second door 21, and a second door lock sensor is arranged on the second door lock. The second door lock sensor is used to collect and send a second door lock status signal, and the second door lock status signal includes a second closing signal and a second release signal. By respectively arranging door lock sensors on the first door lock and the second door lock, the corresponding door lock status signals can be collected in real time and accurately, so that the control unit can determine whether each door is in the open position or the closed position, and avoid the collision between the first door 11 and the second door 21 caused by the misjudgment of the door lock status.

[0076] The first driver 13 is connected to the first door 11 to drive the first door 11 to rotate, the second driver 23 is connected to the second door 21 to drive the second door 21 to rotate, the first sensor 32 is arranged on the vehicle body, and the first sensor 32 is used to collect and send a first door position signal. The second sensor is arranged on the vehicle body, and the second sensor is used to collect and send a second door position signal. The first control unit 31 is used to receive the door opening and closing instructions, the first door lock status signal, the second door lock status signal and the second door position signal, and control the movement state of the first driver 13 and the opening and closing of the first door lock according to the received signals. The second control unit 33 is used to receive the door opening and closing instructions, the first door lock status signal, the second door lock status signal and the first door position signal, and control the movement state of the second driver 23 and the opening and closing of the second door lock according to the received signals.

[0077] For example, an electrical connection is achieved between the first driver 13 and the first control unit 31 through the first wire harness 116. An electrical connection is made between the first control unit 31 and the second sensor through the third wire harness. An electrical connection is established between the first control unit 31 and the first door lock sensor through the fourth wire harness. An electrical connection is formed between the first control unit 31 and the second door lock sensor through the fifth wire harness. The first control unit 31 can determine whether the first door 11 and the second door 21 are in the open position or the closed position based on the first door lock status signal collected by the first door lock sensor and the second door lock status signal collected by the second door lock sensor, and in combination with the second door position signal collected by the second sensor. For example, when the second door 21 is in the open position, the position information of the second door 21 can be confirmed in a timely manner through the second door position signal collected by the second sensor, and then the motion state of the first driver 13 and the opening and closing of the first door lock are controlled, thereby effectively avoiding a collision between the first door 11 and the second door 21. For example, when the second door lock is in the closed state, indicating that the second door 21 is in the closed position, the first control unit 31 can drive the first door 11 to open or close, and at this time, the first door 11 will not collide with the second door 21.

[0078] An electrical connection is achieved between the second driver 23 and the second control unit 33 through the second wire harness 215. An electrical connection is made between the second control unit 33 and the first sensor 32 through the sixth wire harness. An electrical connection is established between the second control unit 33 and the first door lock sensor through the seventh wire harness. An electrical connection is formed between the second control unit 33 and the second door lock controller through the eighth wire harness. The second control unit 33 can determine whether the first door 11 and the second door 21 are in the open position or the closed position based on the first door lock status signal collected by the first door lock sensor and the second door lock status signal collected by the second door lock sensor, and in combination with the first door position signal collected by the first sensor 32. For example, when the first door 11 is in the open position, the position information of the first door 11 can be confirmed in a timely manner through the first door position signal collected by the first sensor 32, and then the motion state of the second driver 23 and the opening and closing of the second door lock are controlled, thereby effectively avoiding a collision between the first door 11 and the second door 21.

[0079] The first control unit 31 receives the door opening / closing instruction, the first door lock status signal, the second door lock status signal, and the second door position signal, and controls the motion state of the first driver 13 and the opening / closing of the first door lock according to the received signals. The second control unit 33 is configured to receive the door opening / closing instruction, the first door lock status signal, the second door lock status signal, and the first door position signal, and control the motion state of the second driver 23 and the opening / closing of the second door lock according to the received signals. In this way, independent control of the first door 11 and the second door 21 can be achieved. There is no need for the first control unit 31 and the second control unit 33 to exchange the position information of the first door 11 and the second door 21, making the control systems of the first door 11 and the second door 21 independent respectively. While effectively avoiding collisions between the first door 11 and the second door 21, the control logic of the first door 11 and the second door 21 can be made simpler, and to a certain extent, the control efficiency of the first door 11 and the second door 21 can be increased.

[0080] Optionally, the first door lock includes a first latch 111, a first lock body 112, a first switch 113, and a first cable. The first latch 111 cooperates with the first lock body 112. The first switch 113 is used to control the connection or disconnection between the first latch 111 and the first lock body 112. The first cable is disposed between the first switch 113 and the first lock body 112. One of the first latch 111 and the first lock body 112 is mounted on the vehicle body, and the other of the first latch 111 and the first lock body 112 is mounted on the first door 11. When the first door 11 is in the closed position, stable connection between the first door 11 and the vehicle body can be achieved through the cooperation of the first latch 111 and the first lock body 112, making the first door 11 more stably held in the closed position.

[0081] The second door lock includes a second latch 211, a second lock body 212, a second switch 213, and a second cable 217. The second latch 211 cooperates with the second lock body 212. The second switch 213 is used to control the connection or disconnection between the second latch 211 and the second lock body 212. The second cable 217 is disposed between the second switch 213 and the second lock body 212. One of the second latch 211 and the second lock body 212 is mounted on the vehicle body, and the other of the second latch 211 and the second lock body 212 is mounted on the second door 21. When the second door 21 is in the closed position, stable connection between the second door 21 and the vehicle body can be achieved through the cooperation of the second latch 211 and the second lock body 212, making the second door 21 more stably held in the closed position.

[0082] According to the split door system 1a of an embodiment of the present invention, the first control unit 31 receives a door opening / closing instruction, a first door lock state signal, a second door lock state signal, and a second door position signal, and controls the motion state of the first driver 13 and the opening / closing of the first door lock according to the received signals. The second control unit 33 is configured to receive the door opening / closing instruction, the first door lock state signal, the second door lock state signal, and a first door position signal, and control the motion state of the second driver 23 and the opening / closing of the second door lock according to the received signals, so as to achieve independent control of the first door 11 and the second door 21. There is no need for the first control unit 31 and the second control unit 33 to exchange the position information of the first door 11 and the second door 21. While effectively avoiding collisions between the first door 11 and the second door 21, the control logic of the first door 11 and the second door 21 can be made simpler.

[0083] Referring to Figures 1-4 , according to some embodiments of the present invention, the first door position signal includes a first avoidance signal, a first safety signal, and a first jump signal. The first avoidance signal is a signal sent by the first sensor 32 when the first door 11 is located within the collision area 1b. The first safety signal is a signal sent by the first sensor 32 when the first door 11 is located within the first safety area. The first jump signal is a signal sent by the first sensor 32 when the first door 11 switches between the first safety area and the collision area 1b. When the first door 11 is located at different positions, the corresponding first door position signals are different. In this way, when the second control unit 33 receives the door opening / closing instruction, the second control unit 33 can judge whether the first door 11 is located in the collision area 1b or the first safety area according to the received first avoidance signal, first safety signal, or first jump signal, and combine the first door lock state signal and the second door lock state signal to control the motion state of the second driver 23 and the opening / closing of the second door lock, so as to effectively avoid collisions between the first door 11 and the second door 21.

[0084] The second door position signal includes a second avoidance signal, a second safety signal, and a second jump signal. The second avoidance signal is the signal sent by the second sensor when the second door 21 is within the collision area 1b. The second safety signal is the signal sent by the second sensor when the second door 21 is within the second safety area. The second jump signal is the signal sent by the second sensor when the second door 21 switches between the second safety area and the collision area 1b. The collision area 1b is located between the first safety area and the second safety area. When the second door 21 is in different positions, the corresponding second door position signals are different. In this way, when the first control unit 31 receives a door opening / closing instruction, the first control unit 31 can judge whether the second door 21 is in the collision area 1b or the second safety area according to the received second avoidance signal, second safety signal, or second jump signal, and combine the first door lock state signal and the second door lock state signal to control the motion state of the first driver 13 and the opening / closing of the first door lock, so as to effectively avoid a collision between the first door 11 and the second door 21.

[0085] It should be noted that the opening positions of the first door 11 and the second door 21 include the maximum opening position, which refers to the position where the first door 11 or the second door 21 rotates the maximum angle along the set path from the closed position.

[0086] Among them, the first door 11 has a first critical position. The first critical position of the first door 11 (for example, it can be referred to as g2 in the figure) is located between the closed position of the first door 11 (for example, it can be referred to as g1 in the figure) and the maximum opening position of the first door 11. When the first door 11 is between the first critical position and the maximum opening position of the first door 11, the first door 11 is in the first safety area.

[0087] Correspondingly, the second door 21 has a second critical position (for example, it can be referred to as s2 in the figure). The second critical position of the second door 21 is located between the closed position of the second door 21 (for example, it can be referred to as s1 in the figure) and the maximum opening position of the second door 21. When the second door 21 is between the second critical position and the maximum opening position of the second door 21, the second door 21 is in the second safety area. The area swept by the second door 21 during the movement from the closed position to the second critical position constitutes the collision area 1b.

[0088] For example, if the second sensor detects that the second door 21 is in the collision area 1b, the second sensor can transmit the second avoidance signal to the first control unit 31, and the first control unit 31 can control the first door 11 to stop moving through the first driver 13 to avoid a collision between the first door 11 and the second door 21.

[0089] For another example, if the first sensor 32 detects that the first vehicle door 11 is located in the collision area 1b, the first sensor 32 can transmit a first avoidance signal to the second control unit 33, and the second control unit 33 can control the second vehicle door 21 to stop moving via the second driver 23 to avoid a collision between the first vehicle door 11 and the second vehicle door 21.

[0090] Referring to Figures 5-7 , according to some embodiments of the present invention, the first control unit 31 is configured to control the motion state of the first driver 13 and the opening and closing of the first vehicle door lock according to the received signal, and the second control unit 33 is configured to control the motion state of the second driver 23 and the opening and closing of the second vehicle door lock according to the received signal, including:

The second control unit 33 is configured to control the release of the second vehicle door lock and control the second driver 23 to drive the second vehicle door 21 to open when receiving the first jump signal;

[0092] When the first vehicle door lock state signal is a first closed signal and the second vehicle door lock state signal is a second closed signal, it indicates that both the first vehicle door 11 and the second vehicle door 21 are in the closed position. At this time, the door opening and closing instructions received by the first control unit 31 and the second control unit 33 are both full open door instructions, so that both the first vehicle door 11 and the second vehicle door 21 move from the closed position to the maximum open position. The first control unit 31 controls the release of the first vehicle door lock and controls the first driver 13 to drive the first vehicle door 11 to move to the maximum open position. When the second control unit 33 receives the first jump signal, it indicates that the first vehicle door 11 moves from the collision area 1b to the first safety area. At this time, the second control unit 33 controls the release of the second vehicle door lock and controls the second driver 23 to drive the second vehicle door 21 to move to the maximum open position, which can effectively prevent a collision between the first vehicle door 11 and the second vehicle door 21.

[0093] When the door opening and closing instructions received by the first control unit 31 and the second control unit 33 are full open door instructions, the first vehicle door lock state signal is a first release signal, and the second vehicle door lock state signal is a second closed signal, the first control unit 31 is configured to control the first driver 13 to drive the first vehicle door 11 to open or control the first driver 13 to remain stationary, and the second control unit 33 is configured to control the second driver 23 and the second vehicle door lock according to the position information of the first vehicle door 11;

At this time, the switch door instructions received by the first control unit 31 and the second control unit 33 are both full open door instructions, so that both the first door 11 and the second door 21 move to the maximum open position.

[0095] If the first door 11 is between the closed position and the maximum open position, the first door 11 may be in the collision area 1b or in the first safety area. If the first door 11 is in the maximum open position, the first control unit 31 controls the first driver 13 not to move. If the first door 11 is between the first critical position and the maximum open position, the first control unit 31 controls the first driver 13 to drive the first door 11 to move to the maximum open position, and the second control unit 33 needs to control the second driver 23 and the second door lock according to the position information of the first door 11 to avoid collision between the first door 11 and the second door 21.

[0096] Among them, if the first door 11 is in the maximum open position, the first control unit 31 controls the first driver 13 not to move. If the first door 11 is between the first critical position and the maximum open position, the first control unit 31 controls the first driver 13 to drive the first door 11 to open, so that the first door 11 moves to the maximum open position.

[0097] When the switch door instructions received by the first control unit 31 and the second control unit 33 are full open door instructions, the first door lock status signal is the first closed signal, and the second door lock status signal is the second release signal, the second control unit 33 is configured to control the second driver 23 to drive the second door 21 to open or control the second driver 23 not to move, and the first control unit 31 is configured to control the first driver 13 and the first door lock according to the position information of the second door 21;

[0098] When the first door lock status signal is the first closed signal and the second door lock status signal is the second release signal, it indicates that the first door 11 is in the closed position and the second door 21 is in the open position. At this time, the switch door instructions received by the first control unit 31 and the second control unit 33 are both full open door instructions, so that both the first door 11 and the second door 21 move to the maximum open position.

[0099] If the second vehicle door 21 is between the closed position and the maximum open position, the second vehicle door 21 may be in the collision area 1b or in the second safety area. If the second vehicle door 21 is in the maximum open position, the second control unit 33 controls the second driver 23 not to move. If the second vehicle door 21 is between the second critical position and the maximum open position, the second control unit 33 controls the second driver 23 to drive the second vehicle door 21 to move to the maximum open position, and the first control unit 31 needs to control the first driver 13 and the first vehicle door lock according to the position information of the second vehicle door 21 to avoid collision between the first vehicle door 11 and the second vehicle door 21.

[0100] Among them, if the second vehicle door 21 is in the maximum open position, the second control unit 33 controls the second driver 23 not to move. If the second vehicle door 21 is between the second critical position and the maximum open position, the second control unit 33 controls the second driver 23 to drive the second vehicle door 21 to open so that the second vehicle door 21 moves to the maximum open position.

[0101] When the door opening and closing instructions received by the first control unit 31 and the second control unit 33 are full door opening instructions, the first vehicle door lock status signal is the first release signal, and the second vehicle door lock status signal is the second release signal, the first control unit 31 is configured to control the first driver 13 and the first vehicle door lock according to the position information of the second vehicle door 21, and the second control unit 33 is configured to control the second driver 23 and the second vehicle door lock according to the position information of the first vehicle door 11.

[0102] When the first vehicle door lock status signal is the first release signal and the second vehicle door lock status signal is the second release signal, it indicates that both the first vehicle door 11 and the second vehicle door 21 are in the open position. At this time, the door opening and closing instructions received by the first control unit 31 and the second control unit 33 are both full door opening instructions, so that both the first vehicle door 11 and the second vehicle door 21 move to the maximum open position.

[0103] If the first vehicle door 11 and the second vehicle door 21 are between the closed position and the maximum open position, the first vehicle door 11 may be in the collision area 1b or in the first safety area, and the second vehicle door 21 may be in the collision area 1b or in the second safety area. The first control unit 31 needs to control the first driver 13 and the first vehicle door lock according to the position information of the second vehicle door 21, and the second control unit 33 needs to control the second driver 23 and the second vehicle door lock according to the position information of the first vehicle door 11 to effectively prevent collision between the first vehicle door 11 and the second vehicle door 21.

[0104] When the door opening and closing instructions received by the first control unit 31 and the second control unit 33 are full door opening instructions, the first control unit 31 controls the motion state of the first driver 13 and the opening and closing of the first vehicle door lock according to the received signals, and the second control unit 33 controls the motion state of the second driver 23 and the opening and closing of the second vehicle door lock according to the received signals, so as to realize the intelligent avoidance of the first vehicle door 11 and the second vehicle door 21, and effectively prevent the first vehicle door 11 and the second vehicle door 21 from colliding.

[0105] Referring to Figure 5 , according to some embodiments of the present invention, when the door opening and closing instructions received by the first control unit 31 and the second control unit 33 are full door opening instructions, the first vehicle door lock state signal is the first release signal, and the second vehicle door lock state signal is the second closing signal, it indicates that the first vehicle door 11 is in the open position and the second vehicle door 21 is in the closed position.

[0106] The second control unit 33 is configured to control the second driver 23 and the second vehicle door lock according to the position information of the first vehicle door 11, including:

[0107] When the first vehicle door position signal received by the second control unit 33 is the first avoidance signal, the second control unit 33 is configured to control the release of the second vehicle door lock and control the second driver 23 to drive the second vehicle door 21 to open when receiving the first jump signal; when the first vehicle door position signal is the first avoidance signal, it indicates that the first vehicle door 11 is located in the collision area 1b. At this time, first, the first control unit 31 controls the first driver 13 to drive the first vehicle door 11 to move to the maximum open position, so that the first vehicle door 11 moves from the collision area 1b to the first safety area. When the second control unit 33 receives the first jump signal, it indicates that the first vehicle door 11 moves from the collision area 1b to the first safety area. At this time, the second control unit 33 controls the release of the second vehicle door lock and controls the second driver 23 to drive the second vehicle door 21 to move to the maximum open position, which can effectively prevent the first vehicle door 11 from colliding with the second vehicle door 21.

[0108] When the first vehicle door position signal received by the second control unit 33 is the first safety signal, the second control unit 33 is configured to control the release of the second vehicle door lock and control the second driver 23 to drive the second vehicle door 21 to open. When the first vehicle door position signal is the first safety signal, it indicates that the first vehicle door 11 is located in the first safety area. Then, the second control unit 33 controls the release of the second vehicle door lock and controls the second driver 23 to drive the second vehicle door 21 to move to the maximum open position. During the process of the second vehicle door 21 moving from the closed position to the maximum open position, the first vehicle door 11 and the second vehicle door 21 will not collide.

[0109] Through the above control logic, when the door opening and closing instructions received by the first control unit 31 and the second control unit 33 are full door opening instructions, the first door lock status signal is the first release signal, and the second door lock status signal is the second closed signal, the second control unit 33 is configured to control the second driver 23 and the second door lock according to the position information of the first door 11, so as to achieve intelligent avoidance between the first door 11 and the second door 21.

The first control unit 31 is configured to control the first driver 13 and the first door lock according to the position information of the second door 21, including:

[0111] When the second door position signal received by the first control unit 31 is the second avoidance signal, the first control unit 31 is configured to control the release of the first door lock and control the first driver 13 to drive the first door 11 to open when receiving the second jump signal; when the second door position signal is the second avoidance signal, it indicates that the second door 21 is located in the collision area 1b. At this time, first make the second control unit 33 control the second driver 23 to drive the second door 21 to move to the maximum open position, so that the second door 21 moves from the collision area 1b to the second safety area. When the first unit receives the second jump signal, it indicates that the second door 21 has moved from the collision area 1b to the second safety area. At this time, the first control unit 31 controls the release of the first door lock and controls the first driver 13 to drive the first door 11 to move to the maximum open position, which can effectively prevent the first door 11 from colliding with the second door 21.

[0112] When the second door position signal received by the first control unit 31 is the second safety signal, the first control unit 31 is configured to control the release of the first door lock and control the first driver 13 to drive the first door 11 to open. When the second door position signal is the second safety signal, it indicates that the second door 21 is located in the second safety area. Then the second control unit 33 controls the second driver 23 not to move, and the second control unit 33 controls the release of the second door lock and controls the second driver 23 to drive the second door 21 to move to the maximum open position. During the process of the second door 21 moving from the closed position to the maximum open position, the first door 11 and the second door 21 will not collide.

[0118] When the first door signal received by the second control unit 33 is the first safety signal, it indicates that the first door 11 is located in the first safety area. The first control unit 31 is configured to control the first driver 13 to drive the first door 11 to open or control the first driver 13 to remain stationary. The second control unit 33 is configured to control the second driver 23 to drive the second door 21 to open or control the second driver 23 to remain stationary. During the process of the second door 21 moving to the maximum open position, the first door 11 will not collide with the second door 21.

[0119] Among them, when the first door 11 is located at the maximum open position, the first control unit 31 controls the first driver 13 to remain stationary. When the first door 11 is between the first critical position and the maximum open position, the first control unit 31 controls the first driver 13 to drive the first door 11 to open so that the first door 11 moves to the maximum open position.

[0120] Correspondingly, when the second door signal received by the first control unit 31 is the second safety signal, it indicates that the first door 11 is located in the first safety area. The first control unit 31 is configured to control the first driver 13 to drive the first door 11 to open or control the first driver 13 to remain stationary. The second control unit 33 is configured to control the second driver 23 to drive the second door 21 to open or control the second driver 23 to remain stationary.

When the second door 21 is between the second critical position and the maximum open position, the second control unit 33 controls the second driver 23 to drive the second door 21 to open so that the second door 21 moves to the maximum open position.

[0122] Through the above control logic, when the door opening and closing instructions received by the first control unit 31 and the second control unit 33 are full door opening instructions, the first door lock status signal is the first release signal, and the second door lock status signal is the second release signal, if the first door position signal received by the second control unit 33 is the first avoidance signal and the second door position signal received by the first control unit 31 is the second avoidance signal, the first control unit 31 is configured to control the first driver 13 not to move, and the second control unit 33 is configured to control the second driver 23 not to move; if the first door position signal received by the second control unit 33 is the first safety signal or the second door position signal received by the first control unit 31 is the second safety signal, the first control unit 31 is configured to control the first driver 13 to drive the first door 11 to open or control the first driver 13 not to move, and the second control unit 33 is configured to control the second driver 23 to drive the second door 21 to open or control the second driver 23 not to move, so as to achieve the intelligent avoidance of the first door 11 and the second door 21.

[0124] When the door opening and closing instructions received by the first control unit 31 and the second control unit 33 are full door closing instructions, the first door lock status signal is the first closing signal, and the second door lock status signal is the second closing signal, the first control unit 31 is configured to control the first driver 13 not to move, and the second control unit 33 is configured to control the second driver 23 not to move;

[0125] When the first door lock status signal is the first closing signal and the second door lock status signal is the second closing signal, it indicates that both the first door 11 and the second door 21 are in the closed position. At this time, the door opening and closing instructions received by the first control unit 31 and the second control unit 33 are both full door closing instructions, that is, the first door 11 and the second door 21 are moved to the closed position. Since the initial states of the first door 11 and the second door 21 are both in the closed position, by controlling the first driver 13 not to move by the first control unit 31 and controlling the second driver 23 not to move by the second control unit 33, the first door 11 and the second door 21 can be kept in the closed position.

[0126] When the door opening and closing instructions received by the first control unit 31 and the second control unit 33 are full-closed door instructions, the first door lock status signal is the first release signal, and the second door lock status signal is the second closed signal, the first control unit 31 is configured to control the first driver 13 to drive the first door 11 to close, and the second control unit 33 is configured to control the second driver 23 not to move;

[0127] When the first door lock status signal is the first release signal and the second door lock status signal is the second closed signal, it indicates that the first door 11 is in the open position and the second door 21 is in the closed position. At this time, the door opening and closing instructions received by the first control unit 31 and the second control unit 33 are both full-closed door instructions, so that the first door 11 and the second door 21 move to the closed position. Since the second door 21 is initially in the closed position, by controlling the second driver 23 not to move through the second control unit 33, the second door 21 can be kept in the closed position, while the first control unit 31 controls the first driver 13 to drive the first door 11 to close. At this time, since the second door 21 is in the closed position, the first door 11 and the second door 21 will not collide during the process of driving the first door 11 to close.

[0128] When the door opening and closing instructions received by the first control unit 31 and the second control unit 33 are full-closed door instructions, the first door lock status signal is the first closed signal, and the second door lock status signal is the second release signal, the first control unit 31 is configured to control the release of the first door lock and control the first driver 13 to drive the first door 11 to open to make room for the closing of the second door 21 when the second door 21 is in the second safety area. The second control unit 33 is configured to control the second driver 23 to drive the second door 21 to close when receiving the first jump signal, and control the first driver 13 to drive the first door 11 to close when the first control unit 31 receives the second closed signal;

[0129] When the first door lock status signal is the first closed signal and the second door lock status signal is the second release signal, it indicates that the first door 11 is in the closed position and the second door 21 is in the open position. At this time, the door opening and closing instructions received by the first control unit 31 and the second control unit 33 are both full-closed door instructions, so that both the first door 11 and the second door 21 are closed.

[0130] The first control unit 31 is configured to control the release of the first door lock and control the first driver 13 to drive the first door 11 to open to create a movement space for the closing of the second door 21 when the second door 21 is in the second safety area. When the first door 11 moves from the collision area 1b to the first safety area, the first door position signal received by the second control unit 33 changes from the first avoidance signal to the first jump signal. At this time, the second control unit 33 controls the second driver 23 to drive the second door 21 to close. When the first control unit 31 receives the second closing signal, it indicates that the second door 21 is in the closed position, which can effectively avoid the collision between the first door 11 and the second door 21.

[0131] When the door opening and closing instructions received by the first control unit 31 and the second control unit 33 are full closing instructions, the first door lock status signal is the first release signal, and the second door lock status signal is the second release signal, the first control unit 31 is configured to control the first driver 13 and the first door lock according to the second door position signal, and the second control unit 33 is configured to control the second driver 23 and the second door lock according to the first door position signal.

[0132] When the first door lock status signal is the first release signal and the second door lock status signal is the second release signal, it indicates that both the first door 11 and the second door 21 are in the open position. At this time, the door opening and closing instructions received by the first control unit 31 and the second control unit 33 are both full closing instructions, so that both the first door 11 and the second door 21 are closed.

[0133] If the first door 11 and the second door 21 are between the closed position and the maximum open position, the first door 11 or the second door 21 may be in the collision area 1b or may be in the first safety area. By configuring the first control unit 31 to control the first driver 13 and the first door lock according to the second door position signal, and the second control unit 33 to control the second driver 23 and the second door lock according to the first door position signal, the collision between the first door 11 and the second door 21 can be effectively prevented.

[0134] Through the above control logic, the intelligent avoidance of the first door 11 and the second door 21 can be realized.

[0135] Refer to Figure 6 , according to some embodiments of the present invention, the first control unit 31 is configured to control the release of the first door lock and control the first driver 13 to drive the first door 11 to open to create a movement space for the closing of the second door 21 when the second door 21 is in the second safety area, including:

[0136] When the second door position signal received by the first control unit 31 is the second avoidance signal, the second control unit 33 is configured to control the second driver 23 to drive the second door 21 to open, and the first control unit 31 is configured to control the release of the first door lock and control the first driver 13 to drive the first door 11 to open to avoid a movement space for the closing of the second door 21 when receiving the second jump signal; when the second door position signal is the second avoidance signal, it indicates that the second door 21 is located in the collision area 1b. The second control unit 33 controls the second driver 23 to drive the second door 21 to open so that the second door 21 moves to the second safe area. When the first control unit 31 receives the second jump signal, it indicates that the second door 21 moves from the collision area 1b to the second safe area. At this time, the first control unit 31 controls the release of the first door lock to facilitate the movement of the first driver 13 to drive the first door 11, and controls the first driver 13 to drive the first door 11 to open to avoid a movement space for the closing of the second door 21.

[0137] When the second door position signal received by the first control unit 31 is the second safety signal, the first control unit 31 is configured to control the release of the first door lock and control the first driver 13 to drive the first door 11 to open to avoid a movement space for the closing of the second door 21. When the second door position signal is the second safety signal, it indicates that the second door 21 is located in the second safe area. The first control unit 31 controls the release of the first door lock to facilitate the movement of the first driver 13 to drive the first door 11, and controls the first driver 13 to drive the first door 11 to open to avoid a movement space for the closing of the second door 21. When the first door 11 moves from the collision area 1b to the first safe area, the first door position signal received by the second control unit 33 changes from the first avoidance signal to the first jump signal. At this time, the second control unit 33 controls the second driver 23 to drive the second door 21 to close. When the first control unit 31 receives the second closing signal, it indicates that the second door 21 is in the closed position, which can effectively avoid the collision between the first door 11 and the second door 21.

[0138] Through the above control logic, the intelligent avoidance of the first door 11 and the second door 21 can be realized, and the collision between the first door 11 and the second door 21 can be effectively avoided.

[0139] Refer to Figure 6, according to some embodiments of the present invention, when the door opening and closing instructions received by the first control unit 31 and the second control unit 33 are full-closed door instructions, the first door lock state signal is the first release signal, and the second door lock state signal is the second release signal, the first control unit 31 is configured to control the first driver 13 and the first door lock according to the second door position signal, and the second control unit 33 is configured to control the second driver 23 and the second door lock according to the first door position signal, including:

[0140] When the first door position signal received by the second control unit 33 is the first avoidance signal and the second door position signal received by the first control unit 31 is the second avoidance signal, the first control unit 31 is configured to control the first driver 13 not to move, and the second control unit 33 is configured to control the second driver 23 not to move;

[0141] When the first door position signal is the first avoidance signal and the second door position signal is the second avoidance signal, it indicates that both the first door 11 and the second door 21 are located in the collision area 1b. At this time, the first control unit 31 is configured to control the first driver 13 not to move, and the second control unit 33 is configured to control the second driver 23 not to move, which can effectively prevent the first door 11 and the second door 21 from colliding.

[0142] When the first door position signal received by the second control unit 33 is the first avoidance signal and the second door position signal received by the first control unit 31 is the second safety signal, the first control unit 31 is configured to control the first driver 13 to drive the first door 11 to open to make room for the closing of the second door 21. The second control unit 33 is configured to control the second driver 23 to drive the second door 21 to close when receiving the first jump signal, and control the first driver 13 to drive the first door 11 to close when the first control unit 31 receives the second closing signal;

[0143] When the first door position signal is the first avoidance signal and the second door position signal is the second safety signal, it indicates that the first door 11 is located in the collision area 1b and the second door 21 is located in the second safety area. The first control unit 31 controls the first driver 13 to drive the first door 11 to open to make room for the closing of the second door 21. When the first door 11 moves from the collision area 1b to the first safety area, the first door position signal received by the second control unit 33 changes from the first avoidance signal to the first jump signal. At this time, the second control unit 33 controls the second driver 23 to drive the second door 21 to close. When the first control unit 31 receives the second closing signal, it indicates that the second door 21 is in the closed position, which can effectively prevent the first door 11 from colliding with the second door 21.

[0144] When the first door position signal received by the second control unit 33 is a first safety signal, the second control unit 33 is configured to control the second driver 23 to drive the second door 21 to close, and the first control unit 31 is configured to control the first driver 13 to drive the first door 11 to close when receiving the second closing signal.

[0145] When the first door position signal is the first safety signal, it indicates that the first door 11 is located in the first safety area. Then the second control unit 33 controls the second driver 23 to drive the second door 21 to close. When the first control unit 31 receives the second closing signal, it indicates that the second door 21 has been in the closed position. By controlling the first driver 13 to drive the first door 11 to close through the first control unit 31, both the first door 11 and the second door 21 can move from the open position to the closed position, and the collision between the first door 11 and the second door 21 can be effectively avoided.

[0146] Through the above control logic, the intelligent avoidance of the first door 11 and the second door 21 can be realized, and the collision between the first door 11 and the second door 21 can be effectively avoided.

[0147] Refer to Figure 7 According to some embodiments of the present invention, the first control unit 31 controls the motion state of the first driver 13 and the opening and closing of the first door lock according to the received signal, and the second control unit 33 controls the motion state of the second driver 23 and the opening and closing of the second door lock according to the received signal, including:

[0148] When the first control unit 31 and the second control unit 33 receive the door opening and closing instruction as a partial opening instruction and the second door lock state signal is a closing signal, the first control unit 31 is configured to control the first driver 13 to drive the first door 11 to open. When the second door lock state signal is a closing signal, it indicates that the second door 21 is in the closed position. When the first control unit 31 receives the partial opening instruction, by controlling the first driver 13 to drive the first door 11 to open through the first control unit 31, since the second door 21 is in the closed position, during the movement of the first door 11, the first door 11 and the second door 21 will not collide.

[0149] When the first control unit 31 and the second control unit 33 receive a partial door opening instruction and the second door lock status signal is a release signal, the first control unit 31 is configured to control the first driver 13 and the first door lock according to the position information of the second door 21. When the second door lock status signal is a release signal, it indicates that the second door 21 is in the open position. Then, the second door 21 may be located in the collision area 1b or in the first safety area. By controlling the first driver 13 and the first door lock by the first control unit 31 according to the position information of the second door 21, it is possible to effectively prevent the first door 11 from colliding with the second door 21.

[0150] Through the above control logic, intelligent avoidance between the first door 11 and the second door 21 can be achieved, effectively avoiding the collision between the first door 11 and the second door 21.

[0151] Refer to Figure 7 , according to some embodiments of the present invention, when the first control unit 31 and the second control unit 33 receive a partial door opening instruction and the second door lock status signal is a release signal, the second door lock status signal being a release signal indicates that the second door 21 is in the open position, and the first control unit 31 is configured to control the first driver 13 and the first door lock according to the position information of the second door 21, including:

[0152] When the second door position signal received by the first control unit 31 is a second avoidance signal and the first door lock status signal received by the first control unit 31 and the second control unit 33 is a first closed signal, the second control unit 33 is configured to control the second driver 23 to drive the second door 21 to open, so as to vacate a movement space for the opening of the first door 11. The first control unit 31 is configured to control the first door lock to release and control the first driver 13 to drive the first door 11 to open when receiving the second jump signal;

[0153] When the second door position signal is the second avoidance signal and the first door lock state signal is the first closed signal, it indicates that the first door 11 is in the closed position and the second door 21 is in the collision area 1b. Since the first control unit 31 and the second control unit 33 receive a partial door opening instruction, the first door 11 and the second door 21 are between the closed position and the maximum open position. The second control unit 33 controls the second driver 23 to drive the second door 21 to open, so as to avoid the movement space of the first door 11 for the opening of the first door 11. When the first control unit 31 receives the second jump signal, it indicates that the second door 21 has moved from the collision area 1b to the second safe area. By controlling the first door lock to release and the first driver 13 to drive the first door 11 to open through the first control unit 31, the first door 11 and the second door 21 can both be in the open position, and the collision between the first door 11 and the second door 21 is effectively prevented.

[0154] When the second door position signal received by the first control unit 31 is the second avoidance signal and the first door position signal received by the second control unit 33 is the first avoidance signal, the first control unit 31 is configured to control the first driver 13 not to move; when the second door position signal is the second avoidance signal and the first door position signal is the first avoidance signal, it indicates that both the first door 11 and the second door 21 are in the collision area 1b. At this time, the first control unit 31 is configured to control the first driver 13 not to move, and the second control unit 33 is configured to control the second driver 23 not to move, so that both the first door 11 and the second door 21 can be in the open position and the collision between the first door 11 and the second door 21 is avoided.

[0155] When the second door position signal received by the first control unit 31 is the safety signal, the first control unit 31 is configured to control the first driver 13 to drive the first door 11 to open. When the second door position signal is the second safety signal, it indicates that the second door 21 is in the second safe area. By controlling the first driver 13 to drive the first door 11 to open through the first control unit 31, the first door 11 and the second door 21 can both be in the open position and the collision between the first door 11 and the second door 21 is avoided.

[0156] Through the above control logic, the intelligent avoidance of the first door 11 and the second door 21 can be realized, and the collision between the first door 11 and the second door 21 can be effectively avoided.

[0157] Refer to Figures 1-4, according to some embodiments of the present invention, both the first sensor 32 and the second sensor are pressure sensing switches. Since both the first sensor 32 and the second sensor are pressure sensing switches, when the first door 11 or the second door 21 switches between the collision area 1b and the first safety area or the second safety area, the signals of the first sensor 32 or the second sensor change. According to the change in the signal of the corresponding sensor, the first control unit 31 or the second control unit 33 can confirm the position information of the first door 11 or the second door 21 in real time and accurately, thereby effectively avoiding the collision of the first door 11 or the second door 21.

[0158] For example, the first door 11 is connected to the vehicle body through a first hinge 114. The first hinge 114 includes a first hinge plate 1141 and a second hinge plate 1142 that are rotatably connected. The first hinge plate 1141 is fixed to the vehicle body, and the second hinge plate 1142 is fixed to the first door 11. The first sensor 32 is provided on the first hinge plate 1141. Since the first sensor 32 is a pressure switch, when the first door 11 is in a position between the collision area 1b and the first safety area, the second hinge plate 1142 will touch the pressure switch and apply a certain pressure. At this time, the pressure switch changes from the off state to the on state, and the pressure switch is activated, causing the signal of the pressure switch to change to confirm the position information of the first door 11.

[0159] For example, when the first door 11 moves from the first critical position to the maximum open position, at least a part of the second hinge plate 1142 can touch the pressure switch and apply a certain pressure. During this process, the first door 11 is in the first safety area, and the pressure switch is in the on state. At this time, the second control unit 33 receives a first safety signal; when the first door 11 moves from the first critical position to the closed position, the second hinge plate 1142 disengages from the pressure switch. During this process, the first door 11 is in the collision area 1b, and the pressure switch is in the off state. At this time, the second control unit 33 receives a first avoidance signal. When the first door 11 is between the collision area 1b and the first safety area, the state of the pressure switch changes, causing the signal of the pressure switch to change. At this time, the second control unit 33 receives a first jump signal, so that the position information of the first door 11 can be confirmed in real time and more accurately.

[0160] Refer to Figures 1-4, according to some embodiments of the present invention, the first sensor 32 is adjacent to the rotational connection between the first vehicle door 11 and the vehicle body, and the second sensor is adjacent to the rotational connection between the second vehicle door 21 and the vehicle body. By the first sensor 32 being adjacent to the rotational connection position between the first vehicle door 11 and the vehicle body, the distance between the first sensor 32 and the first vehicle door 11 can be shortened, so as to improve the accuracy of the position information of the first vehicle door 11 detected by the first sensor 32, and effectively prevent the first vehicle door 11 and the second vehicle door 21 from colliding.

[0161] Correspondingly, by the second sensor being adjacent to the rotational connection position between the second vehicle door 21 and the vehicle body, the distance between the second sensor and the second vehicle door 21 can be shortened, so as to improve the accuracy of the position information of the second vehicle door 21 detected by the second sensor, and effectively prevent the first vehicle door 11 and the second vehicle door 21 from colliding.

[0162] For example, the upper part of the first vehicle door 11 is rotationally connected to the vehicle body, and the lower part of the second vehicle door 21 is rotationally connected to the vehicle body. During the process of the vehicle door moving to the open position, the first vehicle door 11 and the second vehicle door 21 can be made to move away from each other to complete the process of the vehicle door moving to the open position. During the process of the vehicle door moving to the closed position, the first vehicle door 11 and the second vehicle door 21 can be made to move closer to each other to complete the process of the vehicle door moving to the closed position.

[0163] Refer to Figures 1-4 , according to some embodiments of the present invention, the first vehicle door 11 is connected to the vehicle body through a first hinge 114. The first hinge 114 includes a first hinge plate 1141 and a second hinge plate 1142 that are rotatably connected. The first hinge plate 1141 is fixed to the vehicle body, the second hinge plate 1142 is fixed to the first vehicle door 11, and the first sensor 32 is provided on the first hinge plate 1141. The vehicle body can support and fix the first hinge plate 1141, the first vehicle door 11 can support and fix the second hinge plate 1142, and the first hinge plate 1141 can support and fix the first sensor 32, making the assembly of the first sensor 32 on the vehicle body more convenient. Through the relative rotation of the first hinge plate 1141 and the second hinge plate 1142, the rotational connection between the first vehicle door 11 and the vehicle body can be realized.

[0164] The second vehicle door 21 is connected to the vehicle body through a second hinge 214. The second hinge 214 includes a third hinge plate and a fourth hinge plate that are rotatably connected. The third hinge plate is fixed to the vehicle body, the fourth hinge plate is fixed to the second vehicle door 21, and a second sensor is provided on the third hinge plate. The vehicle body can support and fix the third hinge plate, the second vehicle door 21 can support and fix the fourth hinge plate, and the third hinge plate can fix and support the second sensor, making the assembly of the second sensor on the vehicle body more convenient. The third hinge plate and the fourth hinge plate can rotate relative to each other, so as to realize the rotational connection between the second vehicle door 21 and the vehicle body.

[0165] Referring to Figures 1-4 , according to some embodiments of the present invention, the first vehicle door 11 and the second vehicle door 21 are arranged in the up-down direction, and the second vehicle door 21 is located below the first vehicle door 11. When both the first vehicle door 11 and the second vehicle door 21 are in the closed position, the lower end of the first vehicle door 11 covers the outside of the upper end of the second vehicle door 21. When the vehicle door is in the closed position, the lower end of the first vehicle door 11 covering the outside of the upper end of the second vehicle door 21 can enhance the sealing effect of the vehicle door and reduce or avoid the possibility of dust or water entering the vehicle interior through the gap between the first vehicle door 11 and the second vehicle door 21.

[0166] For example, when the vehicle door is in the closed position, the lower side wall of the first vehicle door 11 constitutes a first mating side wall 115, and the upper side wall of the second vehicle door 21 constitutes a second mating side wall 216. The first mating side wall 115 and the second mating side wall 216 are arranged opposite to each other and both the first mating side wall 115 and the second mating side wall 216 extend obliquely downward in the direction from the inside to the outside, so that at least a part of the first mating side wall 115 is located outside the second mating side wall 216, which can enhance the sealing effect of the vehicle door and reduce the possibility of dust or water entering the vehicle interior through the gap between the first vehicle door 11 and the second vehicle door 21.

[0167] Among them, at least a part of the first mating side wall 115 being located outside the second mating side wall 216 can include the following situations: for example, it can be that a part of the first mating side wall 115 is located outside the second mating side wall 216; for another example, it can also be that the entire first mating side wall 115 is located outside the second mating side wall 216.
