It not only eliminates the noise when opening and closing the door, but also avoids the flying of dust on the door body, making the process of opening and closing the door elegant and quiet.

[0003] Because the system resistance is as high as 500N during the self-closing process of the car door, the self-closing motor needs to overcome the 500N system resistance to close the door. When the clamping force of the door reaches 100N, it will cause substantial harm to the user.

[0004] However, the electric suction doors on existing vehicles are very easy to pinch hands during the suction process, causing injuries to users.

[0015] In a preferred technical solution of the above anti-pinch device, the anti-pinch device further comprises a reinforcing member, and the reinforcing member is arranged inside the installation groove and can support and shape the installation groove.

[0016] In a preferred technical solution of the above anti-pinch device, a protrusion structure is further provided on the inner wall of the installation groove, and the protrusion structure abuts against the front end of the rear door to press the rear door tightly into the installation groove.

[0017] In a second aspect, the present invention provides a vehicle, comprising the anti-pinch device described above.

[0018] In a third aspect, the present invention provides a control method, and the specific steps of the control method include: during the self-closing process of the electric suction door, obtaining a current signal on the trigger component; and selectively controlling the electric suction door to stop closing according to the current signal.

[0019] In a fourth aspect, the present invention provides a control system, comprising: an electrically connected signal detection module, a control module, a trigger component and an electric suction door, wherein the signal detection module can detect a current signal on the trigger component and transmit the current signal to the control module, and the control module can control the electric suction door to stop closing after receiving the current signal.

[0020] In the case of adopting the above technical solution, the anti-pinch device of the present invention includes: a sealing strip, which is installed in the door gap of the electric suction door; a trigger component, which includes a first conductor and a second conductor arranged in the sealing strip, and the first conductor and the second conductor are electrically connected to the control circuit of the electric suction door; the first conductor and the second conductor can contact when the sealing strip is squeezed and deformed, so as to turn on the control circuit and then control the electric suction door to stop closing. Through such a setting, on the one hand, it is possible to identify whether a hand is caught in the door gap by measuring the deformation of the sealing strip during the self-closing stage of the door, so as to control the closing motor in time, ensure that the rotation of the closing motor can be stopped in time after the hand is caught, or control the closing motor to reverse to open the door; when the hand is not caught, it can ensure the normal operation of the closing motor to overcome the system resistance during the closing process and make the door body close smoothly.

[0021] Furthermore, the sealing strip is provided with a first weakened portion and a second weakened portion, and the connection line between the first weakened portion and the second weakened portion is perpendicular to the connection line between the first conductor and the second conductor. With such a configuration, when the hand is not pinched, the collapsed portion can fit tightly with the inner side of the door to ensure good sealing between the two; when the hand is pinched, the collapsed portion can be squeezed and move in a direction perpendicular to the connection line between the first weakened portion and the second weakened portion, so that the first conductor can accurately contact the second conductor to conduct the control circuit, thereby improving the accuracy and reliability of the anti-pinch function triggering and making the anti-pinch function highly targeted.

[0022] Furthermore, the first conductor and the second conductor are arranged in a staggered manner to adapt to the structure of the door gap.

[0023] Furthermore, the control circuit is in an open circuit state when the first conductor is separated from the second conductor, and is in a conductive state when the first conductor is in contact with the second conductor. By optimizing the triggering principle of the control circuit, the control circuit is in an open circuit state when the door is normally closed, and the control circuit is turned on to trigger the anti-pinch function only when the hand is pinched. Compared with the control circuit in the normally open state, it can reduce low-voltage energy loss and reduce the risk of large current damaging electronic components.

[0024] Furthermore, the sealing strip is installed between the front door and the rear door of the vehicle, one side of the sealing strip is fixedly connected to the front end of the rear door, and the other side of the sealing strip is in contact with the rear end of the front door. By installing it in the door gap between the front and rear doors, it can prevent the hand from being pinched when the front door is closed, and it can also prevent the hand from being pinched when the rear door is closed; and the front end of the rear door has a small vibration amplitude during the opening and closing of the door body, which helps to firmly connect the sealing strip with the door body, prevent the sealing strip from detaching from the door body during frequent vibrations, ensure the sealing of the door, and extend the service life.

[0025] Furthermore, the sealing strip includes a connecting portion, a fixing portion and a collapsed portion, the connecting portion is fixedly attached to the outer side of the rear door, the fixing portion is fixedly attached to the inclined end surface of the rear door, the collapsed portion is attachedly abutted to the inner side of the front door, the first conductor is arranged on the inner wall of the collapsed portion, and the second conductor is arranged on the inner wall of the fixed portion. By arranging the first conductor and the second conductor on both sides of the door gap relatively, when a hand is pinched, they can be accurately and timely contacted to conduct the control circuit, and at the same time, the sealing between the collapsed portion and the front door can be ensured when the hand is not pinched.

[0026] Furthermore, the width of the first conductor of the present invention is smaller than the width of the second conductor. By setting the first conductor narrower, it can be made more flexible to improve the sensitivity of deformation; and the second conductor can be made wider to increase the area of ​​the second conductor and improve the reliability of the triggering of the two.

[0027] Furthermore, the connection portion of the present invention is provided with a mounting groove, which is fixedly connected to the front end of the rear door. Through such a configuration, a stable connection between the sealing strip and the door body can be achieved with a simple structure, which reduces the processing difficulty and controls the production cost.

[0028] Furthermore, the anti-pinch device of the present invention further comprises a reinforcing member, which is arranged inside the installation groove and can support and shape the installation groove. Through such an arrangement, a stable clamping force of the installation groove can be ensured to prevent loosening in the later stage and affect the stable connection between the sealing strip and the door body.

[0029] Furthermore, a protrusion structure is further provided on the inner wall of the mounting groove of the present invention, and the protrusion structure abuts against the front end of the rear door to press the rear door into the mounting groove. By such a configuration, an interference fit of the rear door in the mounting groove is achieved, and the stability of the connection between the sealing strip and the door body is further improved.

[0030] In addition, the vehicle further provided by the present invention on the basis of the above-mentioned anti-pinch device has the technical effects possessed by the above-mentioned anti-pinch device due to the adoption of the above-mentioned anti-pinch device. Compared with the vehicle before the improvement, the vehicle of the present invention improves the texture and safety of the car door, thereby improving the sense of luxury.

[0060] The preferred embodiments of the present invention are described below with reference to the accompanying drawings. It should be understood by those skilled in the art that these embodiments are only used to explain the technical principles of the present invention and are not intended to limit the protection scope of the present invention.

[0061] It should be noted that in the description of the present invention, the terms "inside", "outside", "upper", "top", "bottom" and the like indicating directions or positional relationships are based on the directions or positional relationships shown in the drawings, which are only for the convenience of description, and do not indicate or imply that the device or element must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as limiting the present invention. In addition, the terms "first" and "second" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance.

[0062] In addition, it should be noted that in the description of the present invention, unless otherwise clearly specified and limited, the terms "set", "install", and "connect" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection. For those skilled in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0063] Based on the problem pointed out in the background technology that the electric suction door on the existing vehicle is very easy to pinch the hand during the suction process, causing the user to be injured. The present invention provides an anti-pinch device for the electric suction door, a vehicle, a control method, and a control system, which aims to achieve the anti-pinch effect by installing a sealing strip with a collapse cavity in the door gap between the front door and the rear door, and installing two conductors arranged at intervals in the collapse cavity, so that the two conductors and the power supply, control module and suction motor form a disconnected control circuit. When the hand is pinched, the sealing strip will be squeezed, so that the two conductors will contact and conduct the control circuit, and then the suction motor will be controlled to stop closing the door body or control the door body to open, so as to achieve the anti-pinch effect.

[0064] For example, when all doors of an ordinary five-door sedan or SUV are closed, the rear edge of the front door meets the front edge of the rear door, forming a narrow door gap between the two. With the improvement of processing and assembly technology, the width of the door gap in the normal closed state is extremely small, making it difficult to insert a finger. However, when the front door or rear door is opened, the width of the door gap will increase, enough to accommodate an adult's finger, which means that once the finger is pinched by the door body, it will be under great pressure, resulting in the finger being pinched.

[0065] In particular, many high-end cars are now equipped with electric suction doors, which can drive the door body to close automatically through the operation of the suction motor. During the door's suction process, the system resistance is as high as 500N, so the self-suction motor needs to overcome the 500N system resistance to close the door body. When the clamping force of the door body reaches 100N, it will cause substantial harm to the user. Therefore, once the user's hand is clamped by the electric suction door, it will cause greater harm.

[0066] In the actual use of the car, many unexpected situations may occur. For example, when the doors are opening and closing, many people will unconsciously put their hands in the gap between the front door and the rear door. If someone closes the front door or the rear door at this time, their hands will be trapped and unable to be pulled out.

[0067] Based on the above reasons, Figure 1 and Figure 2 As shown, the present invention provides an anti-pinch device for an electric suction door, comprising a sealing strip 1 installed in a door gap between a front door 2 and a rear door 3, wherein the sealing strip 1 extends from the top of the door to the bottom of the door along the direction of the door gap.

[0068] Preferably, the sealing strip 1 is installed on the rear door 3. When the front and rear doors 3 are both closed, the sealing strip 1 can just abut against the front door 2 and the rear door 3 at the same time to achieve sealing of the door gap. Specifically, the rear end of the front door 2 is provided with a front door edging 21, and the front end of the rear door 3 is provided with a rear door edging 31. The front door edging 21 is flush with the outer panel of the front door 2 and extends backward. The rear door edging 31 extends inwardly and forwardly along the inclined end surface 32 of the rear door 3 to the inner side of the front door edging 21, so that the two are misaligned. The front door edging 21 and the rear door edging 31 are arranged at intervals along the direction from the outside to the inside of the vehicle body. The front door edging 21, the rear door edging 31 and the inclined end surface 32 form a sealed cavity for accommodating the sealing strip 1, and a door gap that is easy to pinch hands is formed between the front door edging 21 and the inclined end surface 32.

[0069] The sealing strip 1 includes a connecting portion 13, a fixing portion 14 and a collapsed portion 15 connected end to end, so that the cross section of the sealing strip 1 is an annular structure, the connecting portion 13 is fixedly attached to the outer side of the rear door edge 31, the fixing portion 14 is fixedly attached to the inclined end surface 32, the collapsed portion 15 is attachedly abutted to the inner side of the front door edge 21, the first conductor 41 is arranged on the inner wall of the collapsed portion 15, and the second conductor 42 is arranged on the inner wall of the fixing portion 14, so that the first conductor 41 and the second conductor 42 are arranged on both sides of the door gap opposite to each other, and the first conductor 41 can move with the deformation of the collapsed portion 15. And, as Figure 3 As shown, the first conductor 41 and the second conductor 42 together with the vehicle's power supply 5 , the control module 6 and the pull-in motor 7 form a control circuit.

[0070] Specifically, when the door body is closed to the final closing stage, the closing motor 7 starts to run to drive the door body to rotate inward. If no fingers are caught in the door gap, such as Figure 1 As shown, the sealing strip 1 will only be slightly squeezed by the front door edge 21, and will not be greatly deformed. The collapsed portion 15 will maintain an abutment state with the inner side of the front door edge 21, so that the collapsed portion 15 and the inner side of the front door edge 21 are closely fitted to ensure good sealing. At this time, the first conductor 41 and the second conductor 42 are always in a separated state, and the control circuit will not be triggered, so that the control circuit is always in a disconnected state.

[0071] If your finger is caught in the door, Figure 2 As shown, the collapsed portion 15 will be squeezed inward to cause a greater deformation. Accordingly, the first conductor 41 will move inward with the deformation of the collapsed portion 15, and contact the second conductor 42 to turn on the control circuit, thereby controlling the suction motor 7 to stop or reverse, so that the door body stops suction or reopens, avoiding substantial damage to the fingers.

[0072] Preferably, the spacing between the first conductor 41 and the second conductor 42 under normal conditions is maintained between 5mm and 6mm. The setting of this distance should be neither too far nor too close, so as to ensure that the deformation caused by the finger being pinched is sufficient to make the first conductor 41 and the second conductor 42 contact; and prevent the normal vibration of the door body from causing the first conductor 41 and the second conductor 42 to accidentally contact.

[0073] like Figure 1 and Figure 2 As shown, in a preferred embodiment of the present invention, a first weakened portion 11 is further provided on the sealing strip 1 at the connection between the collapsed portion 15 and the connecting portion 13, and a second weakened portion 12 is provided at the connection between the collapsed portion 15 and the fixed portion 14, and a connecting line between the first weakened portion 11 and the second weakened portion 12 is nearly parallel to the fixed portion 14, so that the collapsed portion 15 can move toward the fixed portion 14 when squeezed.

[0074] Specifically, Figure 1 As shown, when the hand is not pinched, the collapsed portion 15 is only subjected to the inward pressure along the width direction of the vehicle body exerted by the front door edging 21, and the pressure is relatively small, which can only make the collapsed portion 15 fit tightly against the inner side of the front door edging 21 to ensure good sealing between the two.

[0075] like Figure 2 As shown, when the hand is pinched, the fingers will apply inward and rearward pressure to the collapsed portion 15. Therefore, the first weakened portion 11 and the second weakened portion 12 are weakened to reduce the strength of these two positions. When subjected to pressure, they will be deformed first, so that the collapsed portion 15 can move in a direction perpendicular to the line between the first weakened portion 11 and the second weakened portion 12 after being squeezed, so as to ensure that the first conductor 41 can accurately contact the second conductor 42 to turn on the control circuit, thereby improving the accuracy and reliability of the anti-pinch function triggering and making the anti-pinch function more targeted.

[0076] It should be noted that, in practical applications, there are many ways to process the first weakened portion 11 and the second weakened portion 12. For example, the thickness of these two positions can be processed to be thinner than other positions, or softer materials can be used at these two positions than at other positions, and so on. As long as the purpose of weakening can be achieved, such flexible adjustments and changes do not deviate from the principle and scope of the present invention and should be limited within the protection scope of the present invention.

[0077] In order to further prevent the conventional system vibration from causing the first conductor 41 and the second conductor 42 to contact each other accidentally, and to ensure the reliability of the contact between the two when the hand is pinched, as shown in FIG. Figure 1 and Figure 2 As shown, in the present application, the width of the first conductor 41 is smaller than the width of the second conductor 42. Preferably, the first conductor 41 is configured as a conductive wire, and the second conductor 42 is configured as a conductive tape with a certain width.

[0078] In addition, regarding the installation structure of the sealing strip 1 and the rear door 3, preferably, as Figure 1 and Figure 2 As shown, a mounting groove 16 is provided on the connecting portion 13, and the mounting groove 16 is clamped on the rear door edge 31. A simple structure is used to achieve a stable connection between the sealing strip 1 and the door body, which reduces the processing difficulty and controls the production cost.

[0079] Preferably, if Figure 1 and Figure 2As shown, a reinforcing member 161 is embedded in the installation groove 16. The reinforcing member 161 is configured as a groove-shaped structure that matches the installation groove 16. It uses a harder material, such as metal, etc., and can support and shape the installation groove 16 to ensure that the installation groove 16 has a stable clamping force to prevent loosening in the later stage and affect the stable connection between the sealing strip 1 and the door body.

[0080] A protrusion structure 162 is also provided on the inner wall of the installation groove 16, and the protrusion structure 162 abuts against the rear door edge 31, and can press the rear door edge 31 into the installation groove 16. Thus, an interference fit between the rear door edge 31 and the installation groove 16 is achieved, further improving the stability of the connection between the sealing strip 1 and the door body, and preventing the sealing strip 1 from falling off.

[0081] In addition, the vehicle further provided by the present invention on the basis of the above-mentioned anti-pinch device has the technical effects possessed by the above-mentioned anti-pinch device due to the adoption of the above-mentioned anti-pinch device. Compared with the vehicle before the improvement, the vehicle of the present invention improves the texture and safety of the car door, thereby improving the sense of luxury.

[0082] Finally, if Figure 4 and Figure 5 As shown, the present invention also provides a control method and a control system, both of which can control the electric suction door during the self-closing process, effectively avoiding damage to passengers caused by the electric suction door during the closing process.

[0083] So far, the technical solutions of the present invention have been described in conjunction with the preferred embodiments shown in the accompanying drawings. However, it is easy for those skilled in the art to understand that the protection scope of the present invention is obviously not limited to these specific embodiments. Without departing from the principle of the present invention, those skilled in the art can make equivalent changes or substitutions to the relevant technical features, and the technical solutions after these changes or substitutions will fall within the protection scope of the present invention.
