[0045] In order to more clearly understand the above-mentioned objectives, features and advantages of the present disclosure, the scheme of the present disclosure will be further described below. It should be noted that the embodiments of the present disclosure and the features in the embodiments can be combined with each other without conflict.

[0046] In the following description, many specific details are set forth to facilitate a full understanding of the present disclosure, but the present disclosure may also be implemented in other ways different from those described herein; it is obvious that the embodiments in the specification are only part of the embodiments of the present disclosure, rather than all of the embodiments.

[0047] It should be noted that, in this article, relational terms such as "first" and "second" are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the term "comprises" or any other variant thereof is intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, the elements defined by the sentence "comprise a ..." do not exclude the existence of other identical elements in the process, method, article or device including the elements.

[0048] It should be noted that the words first direction X, second direction Y and third direction Z that appear in the following description are only used to more clearly illustrate the specific structure of the present application in conjunction with the drawings, and the present application is not limited thereto. The first direction X is roughly the front-to-back direction of the vehicle, the second direction Y is roughly the height direction of the vehicle, and the third direction Z is roughly the width direction of the vehicle. The first direction X, the second direction Y and the third direction Z have an angle between each other. Optionally, the first direction X, the second direction Y and the third direction Z are perpendicular to each other.

[0049] like Figures 1 to 3 As shown, an embodiment of the present application provides a vehicle door anti-pinch system, wherein the vehicle door anti-pinch system includes a detection device 1 and a control device 2.

[0050] The detection device 1 is installed on the vehicle door 4. When the vehicle door 4 is in an open state, a detection area is formed between the vehicle door 4 and the vehicle body door frame 5. The detection device 1 is used to detect and determine whether there is an object in the detection area; wherein the detection device 1 can directly detect the detection area in a sensing manner, or the detection device 1 can detect and analyze the relative position of the driver or objects around the vehicle and the vehicle to determine whether there is an object in the detection area.

[0051] The control device 2 is installed on the vehicle door 4, and the control device 2 is electrically connected to the detection device 1 and the self-priming lock 6 respectively; the detection result of the detection device 1 is fed back to the control device 2, and the control device 2 controls the self-priming lock 6 according to the judgment result fed back by the detection device 1.

[0052] Specifically, when the detection device 1 determines that there is an object in the area to be detected, the control device 2 controls the self-priming lock 6 to cut off the power. After the self-priming lock 6 is powered off, it cannot provide adsorption capacity between the vehicle door 4 and the vehicle body door frame 5, so that the vehicle door 4 cannot be automatically sucked and closed. This can effectively prevent the vehicle door 4 from automatically closing when there is an object in the area to be detected, causing the object to be clamped and damaged, thereby improving the consumer's user experience; when the detection device 1 determines that there is no object in the area to be detected, the self-priming lock 6 remains powered on. At this time, the self-priming lock 6 works normally. After the distance between the vehicle door 4 and the vehicle body door frame 5 reaches the adsorption distance, the vehicle door 4 will automatically close to improve the convenience of closing the vehicle door 4.

[0053] like Figures 1 to 3 As shown, the vehicle door anti-pinch system provided by the embodiment of the present application, wherein the detection device 1 includes a video acquisition component 11 and a data analysis component 12.

[0054] The video acquisition component 11 is used to capture or scan the body position of the driver and passenger to obtain video data; the video acquisition component 11 may be a camera or a scanner, etc., through which the body behavior status of the driver and passenger may be obtained in real time, continuously and dynamically to ensure the accuracy and timeliness of the video data.

[0055] The data analysis component 12 is electrically connected to the video acquisition component 11. The video data collected by the video acquisition component 11 is transmitted to the data analysis component 12 in real time. The data analysis component 12 is used to analyze the video data and determine whether the driver's limbs are located in the area to be detected.

[0056] Since the hands of the driver and the vehicle are mainly in contact when the driver and the passenger interact with the vehicle, the limbs of the driver and the passenger mentioned in the above embodiments must include the hands of the driver and the positions of other parts of the limbs of the driver and the passenger can be flexibly selected as needed.

[0057] Optionally, in the vehicle door anti-pinch system provided by the embodiment of the present application, the video acquisition component 11 is arranged on the outer side of the vehicle door 4 and / or the inner side of the vehicle door 4 .

[0058] The video acquisition component 11 arranged on the outside of the vehicle door 4 mainly collects the body position of the driver and passenger when the driver and passenger are outside the vehicle. The video acquisition component 11 arranged on the inside of the vehicle door 4 mainly collects the body position of the driver and passenger when the driver and passenger are inside the vehicle, so as to improve the door closing safety when the driver and passenger are both inside and outside the vehicle and prevent the driver and passenger from being pinched and injured.

[0059] like Figures 1 to 3As shown, an anti-pinch system for vehicle door provided by an embodiment of the present application, wherein, along a first direction X, the vehicle door 4 has a connecting side 41 and an opening and closing side 42, the connecting side 41 is rotatably connected to the vehicle body door frame 5, the opening and closing side 42 can move in a direction away from the vehicle body door frame 5 to open the vehicle door 4, and the opening and closing side 42 can move in a direction close to the vehicle body door frame 5 to close the vehicle door 4; because the driver and passengers get on and off the vehicle between the opening and closing side 42 and the vehicle body door frame 5, the video acquisition component 11 is located on the connecting side 41, and the video acquisition component 11 is set toward the opening and closing side 42 to ensure the acquisition viewing angle and acquisition range of the video acquisition component 11.

[0060] like Figure 2 As shown, when the door anti-pinch system provided by the embodiment of the present application is applied to the front door of the vehicle, the video acquisition component 11 can be directly installed on the rearview mirror 45 or at the front edge of the window frame of the door 4. When the door anti-pinch system provided by the embodiment of the present application is applied to the rear door of the vehicle, it can be directly installed at the front edge of the window frame of the door 4.

[0061] Optionally, in the vehicle door anti-pinch system provided by the embodiment of the present application, the detection device 1 also includes a sensing component, the sensing component is connected to the vehicle door 4 and / or the vehicle body door frame 5, and the sensing component directly senses whether there is an object in the area to be detected.

[0062] The sensing component can be an infrared sensor, including a transmitting element and a receiving element. The transmitting element is installed on one of the opening and closing sides 42 of the door 4 and the vehicle body door frame 5, and the receiving element is installed on the other of the opening and closing sides 42 of the door 4 and the vehicle body door frame 5. The transmitting element can emit infrared rays, and the receiving element is used to receive infrared rays. When an object is located in the area to be detected, the infrared rays are cut off and the receiving element cannot receive the infrared rays. At this time, it is determined that there is an object in the area to be detected. In this way, it can be more intuitive and accurate to detect whether there is an object in the area to be detected.

[0063] like Figures 1 to 3 As shown, an anti-pinch system for vehicle doors provided in an embodiment of the present application, wherein the anti-pinch system for vehicle doors further comprises a prompting device 3, which is installed on the vehicle door 4, and the prompting device 3 is electrically connected to the control device 2. When the detection device 1 determines that there is an object in the area to be detected, the control device 2 controls the prompting device 3 to send a prompting signal to remind the driver and passengers that there is an object in the area to be detected and the vehicle door 4 cannot be closed, so that the driver and passengers can move the object in the area to be detected out.

[0064] Optionally, the prompting device 3 includes a sound prompter or a light prompter.

[0065] The sound prompter can play prompt audio, which can be music or voice.

[0066] The light prompter can emit a prompt light, which can be a constant light or a flashing light.

[0067] Optionally, the prompt device 3 can be installed on the door handle 46 of the vehicle door 4, which is close to the driver and passengers. When the prompt audio is played, the driver and passengers can hear it, and when the prompt light is emitted, the driver and passengers can quickly find it when operating the door handle 46 of the vehicle door 4.

[0068] The embodiment of the present application provides a door anti-pinch system, wherein, when the door 4 is in an open state, there is a distance between the opening and closing side 42 and the vehicle body door frame 5; the area to be detected includes the area between the opening and closing side 42 and the vehicle body door frame 5. Since the opening and closing side 42 extends from the top of the vehicle body to the bottom of the vehicle body, during the process of the driver and passengers getting on and off the vehicle, the area between the opening and closing side 42 and the vehicle body door frame 5 is most likely to be pinched. Therefore, the area between the opening and closing side 42 and the vehicle body door frame 5 is used as the area to be detected, which can effectively avoid the state of most objects being pinched.

[0069] Optionally, in the vehicle door anti-pinch system provided by the embodiment of the present application, the vehicle door 4 has a first side 43 and a second side 44 arranged opposite to each other along the second direction Y; the first direction X is perpendicular to the second direction Y; when the vehicle door 4 is in an open state, there is a distance between the first side 43 and the second side 44 and the vehicle door frame 5; the area to be detected includes the area between the first side 43 and the vehicle door frame 5 and the area between the second side 44 and the vehicle door frame 5. In this way, all positions where a gap is formed between the vehicle door 4 and the vehicle door frame 5 can be detected, thereby avoiding the situation where the driver or objects are pinched to the greatest extent.

[0070] The embodiment of the present application further provides a vehicle door 4 assembly, wherein the vehicle door 4 assembly includes the vehicle door anti-pinch system as described above.

[0071] The vehicle door 4 assembly provided in the embodiment of the present application is provided with a vehicle door anti-pinch system. The vehicle door anti-pinch system detects the area to be detected between the vehicle door 4 and the vehicle body door frame 5 through the detection device 1 when the vehicle door 4 is in a non-closed state, and determines whether there is an object in the area to be detected. When it is determined that there is an object in the area to be detected, the electrical connection of the self-priming lock 6 is cut off through the control device 2, so that the self-priming lock 6 cannot be automatically closed to close the vehicle door 4. In this way, it can effectively prevent the vehicle door 4 from automatically closing when there is an object in the area to be detected, causing the object to be clamped and damaged, thereby improving the consumer's user experience.

[0072] An embodiment of the present application also provides a vehicle, wherein the vehicle includes a body and a plurality of door assemblies as described above, at least one body door frame 5 is formed on both sides of the body along a third direction Z, and a door 4 assembly is installed at each body door frame 5 .

[0073] The vehicle provided in the embodiment of the present application has a door anti-pinch system adopted in its door 4 assembly. By setting a detection device 1, when the door 4 is in a non-closed state, the detection area between the door 4 and the vehicle body door frame 5 is detected, and it is determined whether there is an object in the detection area. When it is determined that there is an object in the detection area, the electrical connection of the self-priming lock 6 is cut off by the control device 2, so that the self-priming lock 6 cannot be automatically sucked in to close the door 4. In this way, it can effectively prevent the door 4 from automatically closing when there is an object in the detection area, causing the object to be clamped and damaged, thereby improving the consumer's user experience.

[0074] like Figure 4 As shown, the embodiment of the present application further provides a door anti-pinch method, wherein the door anti-pinch method is implemented by the door anti-pinch system as described above, and the door anti-pinch method includes:

[0075] When the door is in an open state, a certain distance exists between a portion of the edge of the door and the door frame of the vehicle body, and a detection area is set at a position where the distance exists between the door and the door frame of the vehicle body;

[0076] Detect the area to be detected and determine whether there is an object in the area to be detected; directly detect the area to be detected by direct sensing, or detect and analyze the relative position of the driver or object around the vehicle and the vehicle to determine whether there is an object in the area to be detected;

[0077] When it is determined that there is an object in the area to be detected, the power supply of the self-priming lock is cut off. After the self-priming lock is powered off, it cannot provide adsorption ability between the door and the door frame, so that the door cannot be automatically closed. This can effectively prevent the door from automatically closing when there is an object in the area to be detected, causing the object to be caught and damaged, thereby improving the user experience of consumers;

[0078] When it is determined that there is no object in the area to be detected, the self-priming lock remains energized. At this time, the self-priming lock works normally. After the distance between the door and the door frame reaches the adsorption distance, the door will automatically close to improve the convenience of closing the door.

[0079] The embodiment of the present application provides a method for preventing vehicle doors from being pinched, wherein, along a first direction, the vehicle door has a connecting side and an opening and closing side that are relatively arranged, the connecting side is rotatably connected to the vehicle body door frame, the opening and closing side can move in a direction away from the vehicle body door frame to open the vehicle door, and the opening and closing side can move in a direction close to the vehicle body door frame to close the vehicle door; when the vehicle door is in a non-closed state, there is a distance between the opening and closing side and the vehicle body door frame.

[0080] When the door is in an open state, a detection area is set between the door and the door frame, including:

[0081] The area to be detected is set to include the area between the opening and closing side and the vehicle body door frame. Since the opening and closing side extends from the top of the vehicle body to the bottom of the vehicle body, passengers are most likely to be pinched in the area between the opening and closing side and the vehicle body door frame during getting on and off the vehicle. Therefore, the area between the opening and closing side and the vehicle body door frame is used as the area to be detected, which can effectively avoid most objects from being pinched.

[0082] The embodiment of the present application provides a method for preventing vehicle door from being pinched, wherein, along the second direction, the vehicle door has a first side and a second side that are arranged opposite to each other; and there is a distance between the first side and the second side and the vehicle door frame.

[0083] When the door is in an open state, a detection area is set between the door and the door frame of the vehicle body, and also includes:

[0084] The area to be detected is set to include the area between the first side and the vehicle body door frame and the area between the second side and the vehicle body door frame. In this way, all positions where a gap is formed between the vehicle door and the vehicle body door frame can be detected, thereby avoiding the situation where the driver or the object is pinched to the greatest extent.

[0085] The door anti-pinch method provided by the embodiment of the present application, wherein the detection area is detected and whether there is an object in the detection area is determined, including:

[0086] The limb position information of the driver and passenger is obtained in real time, continuously and dynamically, the limb position information data is analyzed, and it is determined whether the limb of the driver and passenger is located in the area to be detected.

[0087] Since the hands of the driver and the vehicle are mainly in contact when the driver and the passenger interact with the vehicle, the above-mentioned limb position information of the driver and the passenger must include the hand position information of the driver and the passenger. The position information of other parts of the driver and the passenger's limbs can be flexibly selected as needed.

[0088] Optionally, the limb position information of the driver or passenger is obtained by photographing or scanning, and the limb position information of the driver or passenger may be video data.

[0089] The vehicle door anti-pinch method provided by the embodiment of the present application, wherein, when it is determined that there is an object in the area to be detected, the vehicle door anti-pinch method further includes:

[0090] A prompt signal is sent to remind the driver and passengers that there is an object in the area to be detected and the door cannot be closed, so that the driver and passengers can move the object out of the area to be detected.

[0091] The prompt signal includes a sound signal and / or a light signal, so that the driver and the passenger can obtain the prompt signal through hearing or vision.

[0092] The vehicle door anti-pinch method provided by the present application detects the area to be detected between the vehicle door and the vehicle body door frame when the vehicle door is in an unclosed state, and determines whether there is an object in the area to be detected. When it is determined that there is an object in the area to be detected, the electrical connection of the self-priming lock is cut off, so that the self-priming lock cannot automatically close to close the vehicle door. In this way, it can effectively prevent the vehicle door from automatically closing when there is an object in the area to be detected, causing the object to be pinched and damaged, thereby improving the consumer's user experience.
