Description

Technical Field

[0001] This invention relates to the field of vehicle technology, specifically providing an anti-pinch device for an electric suction door, as well as a vehicle, control method, and control system. Background Technology

[0002] In recent years, with the continuous improvement of user demand, the luxury configurations on passenger cars have become more and more abundant. For example, more and more high-end cars are equipped with electric suction doors, which can realize the automatic and smooth opening and closing of the door. This not only eliminates the noise when opening and closing the door, but also prevents dust from flying on the door, making the process of opening and closing the door elegant and quiet.

[0003] During the self-closing process of the car door, the system resistance is as high as 500N, which means that 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 damage to the user.

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

[0005] Therefore, a new technical solution is needed in this field to solve the above problems. Summary of the Invention

[0006] The present invention aims to solve the above-mentioned technical problem, namely, the problem that electric suction doors on existing vehicles are very easy to pinch hands during the suction process, causing injury to users.

[0007] In a first aspect, the present invention provides an anti-pinch device for an electric suction door, the anti-pinch device comprising: a sealing strip installed in the door gap of the electric suction door; and a triggering component comprising a first conductor and a second conductor disposed within the sealing strip, the first conductor and the second conductor being electrically connected to the control circuit of the electric suction door; the first conductor and the second conductor being able to contact each other when the sealing strip is compressed and deformed, so as to conduct the control circuit and thereby control the electric suction door to stop closing.

[0008] In the preferred embodiment of the above-mentioned anti-pinch device, the sealing strip is further provided with a first weakening part and a second weakening part, and the line connecting the first weakening part and the second weakening part is perpendicular to the line connecting the first conductor and the second conductor.

[0009] In the preferred embodiment of the above-mentioned anti-pinch device, the first conductor and the second conductor are arranged in a staggered manner to adapt to the structure of the door gap.

[0010] In the preferred embodiment of the above-mentioned anti-pinch device, the control circuit is in an open circuit state when the first conductor and the second conductor are separated, and in a closed circuit state when the first conductor and the second conductor are in contact.

[0011] In the preferred embodiment of the above-mentioned anti-pinch device, 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 abuts against the rear end of the front door.

[0012] In the preferred embodiment of the above-mentioned anti-pinch device, the sealing strip includes a connecting part, a fixing part, and a collapsible part. The connecting part is fitted and fixed to the outer side of the rear door, the fixing part is fitted and fixed to the inclined end face of the rear door, and the collapsible part is fitted and abutted to the inner side of the front door. The first conductor is disposed on the inner wall of the collapsible part, and the second conductor is disposed on the inner wall of the fixing part.

[0013] In the preferred embodiment of the above-mentioned anti-pinch device, the width of the first conductor is smaller than the width of the second conductor.

[0014] In the preferred embodiment of the above-mentioned anti-pinch device, the sealing strip is provided with an installation groove, and the installation groove is fixedly connected to the front end of the rear door.

[0015] In the preferred embodiment of the above-mentioned anti-pinch device, the anti-pinch device further includes a reinforcing member, which is disposed inside the mounting groove and can support and shape the mounting groove.

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

[0017] In a second aspect, the present invention provides a vehicle that includes the aforementioned anti-pinch device.

[0018] In a third aspect, the present invention provides a control method, the specific steps of which include: acquiring a current signal on the trigger component during the self-closing process of the electric suction door; and selectively controlling the electric suction door to stop closing based on 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; the signal detection module is capable of detecting a current signal on the trigger component and transmitting the current signal to the control module; the control module is capable of controlling the electric suction door to stop closing upon receiving the current signal.

[0020] With the above technical solution adopted, the anti-pinch device of the present invention includes: a sealing strip installed in the door gap of the electric suction door; a triggering component including a first conductor and a second conductor disposed within the sealing strip, both the first conductor and the second conductor being electrically connected to the control circuit of the electric suction door; the first conductor and the second conductor can contact each other when the sealing strip is squeezed and deformed, so as to conduct the control circuit and thereby control the electric suction door to stop closing. With this setting, on the one hand, it is possible to identify whether a hand is pinched in the door gap by the deformation of the sealing strip during the self-closing stage of the car door, so as to control the suction motor in time, ensuring that the rotation of the suction motor can be stopped in time or the suction motor can be reversed to open the car door after the hand is pinched; when the hand is not pinched, it is possible to ensure that the suction motor operates normally to overcome the system resistance during the suction process and allow the door to close smoothly.

[0021] Furthermore, the sealing strip is also provided with a first weakened portion and a second weakened portion, and the line connecting the first weakened portion and the second weakened portion is perpendicular to the line connecting the first conductor and the second conductor. This arrangement ensures that when the hand is not pinched, the collapsible portion can fit tightly against the inside of the door, guaranteeing a good seal between them; when the hand is pinched, the collapsible portion, after being compressed, can move along a direction perpendicular to the line connecting the first and second weakened portions, allowing the first conductor to accurately contact the second conductor to conduct the control circuit. This improves the accuracy and reliability of the anti-pinch function triggering, making the anti-pinch function highly targeted.

[0022] Furthermore, the first conductor and the second conductor are staggered to accommodate the structure of the door gap.

[0023] Furthermore, the control circuit is in an open-circuit state when the first conductor and the second conductor are separated, and in a closed-circuit state when the first conductor and the second conductor are in contact. 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 is only turned on to trigger the anti-pinch function when a hand is pinched. Compared with the control circuit in the normally open state, this can reduce low-voltage energy loss and reduce the risk of high current damage to electronic components.

[0024] Furthermore, a sealing strip is installed between the front and rear doors of the vehicle. One side of the sealing strip is fixedly connected to the front end of the rear door, and the other side abuts against the rear end of the front door. By being installed in the door gap between the front and rear doors, it can prevent hands from being pinched when the front door closes, as well as when the rear door closes. Moreover, the front end of the rear door experiences less vibration during the opening and closing process, which helps to ensure a stable connection between the sealing strip and the door body, preventing the sealing strip from detaching from the door body due to frequent vibration, thus ensuring the door's sealing performance and extending its service life.

[0025] Furthermore, the sealing strip includes a connecting part, a fixing part, and a collapsible part. The connecting part is fitted and fixed to the outer side of the rear door, the fixing part is fitted and fixed to the inclined end face of the rear door, and the collapsible part is fitted and abutted against the inner side of the front door. A first conductor is disposed on the inner wall of the collapsible part, and a second conductor is disposed on the inner wall of the fixing part. By arranging the first and second conductors opposite each other on both sides of the door gap, accurate and timely contact can be made to conduct the control circuit when a hand is pinched, while ensuring the seal between the collapsible part and the front door when no hand is pinched.

[0026] Furthermore, the width of the first conductor in this invention is smaller than the width of the second conductor. This arrangement allows the narrower first conductor to be more flexible, thereby increasing its sensitivity to deformation; and the wider second conductor increases its area, improving the reliability of their triggering.

[0027] Furthermore, the connecting part of the present invention is provided with a mounting groove, which is fixedly connected to the front end of the rear door. This design allows for a stable connection between the sealing strip and the door body using a simple structure, reducing processing difficulty and controlling production costs.

[0028] Furthermore, the anti-pinch device of the present invention also includes a reinforcing member disposed inside the mounting groove, which can support and shape the mounting groove. This arrangement ensures a stable clamping force in the mounting groove, preventing loosening later and ensuring a secure connection between the sealing strip and the door body.

[0029] Furthermore, the inner wall of the mounting groove of the present invention is provided with a protruding structure, which abuts against the front end of the rear door to press the rear door tightly into the mounting groove. This design achieves an interference fit between the rear door and the mounting groove, further improving the stability of the connection between the sealing strip and the door body.

[0030] Furthermore, the vehicle provided by the present invention, based on the aforementioned anti-pinch device, possesses the technical effects of the aforementioned anti-pinch device due to the adoption of the aforementioned anti-pinch device. Compared with the vehicle before the improvement, the vehicle of the present invention improves the texture and safety of the door, thereby enhancing the sense of luxury.

[0060] Preferred embodiments of the present invention will now be described with reference to the accompanying drawings. Those skilled in the art should understand that these embodiments are merely illustrative of the technical principles of the present invention and are not intended to limit the scope of protection of the present invention.

[0061] It should be noted that in the description of this invention, terms such as "inner," "outer," "upper," "top," and "bottom," which indicate direction or positional relationships, are based on the direction or positional relationships shown in the accompanying drawings. These are used merely for ease of description and do not indicate or imply that the device or element must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0062] Furthermore, it should be noted that, in the description of this invention, unless otherwise explicitly specified and limited, the terms "set," "install," and "connect" should be interpreted broadly, for example, referring to a fixed connection, a detachable connection, or an integral connection. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0063] Based on the background art, existing electric suction doors on vehicles are prone to pinching hands during the suction process, causing user injury. This invention provides an anti-pinch device for electric suction doors, a vehicle, a control method, and a control system. The aim is to install a sealing strip with a collapsible cavity in the door gap between the front and rear doors, and to install two spaced conductors within the collapsible cavity. These two conductors, along with a power supply, a control module, and a suction motor, form an open control circuit. When a hand is pinched, the sealing strip is squeezed, causing the two conductors to contact and connect to the control circuit. This, in turn, controls the suction motor to stop closing the door or opens the door, achieving the anti-pinch effect.

[0064] For example, in a typical five-door sedan or SUV, when all doors are closed, the rear edge of the front door meets the front edge of the rear door, forming a narrow gap between them. With advancements in manufacturing and assembly processes, this gap is extremely narrow when normally closed, making it difficult to insert a finger. However, when either the front or rear door is opened, the gap widens significantly, enough to accommodate an adult's finger. This means that if a finger gets caught in the door, it will experience considerable pressure, potentially leading to injury.

[0065] In particular, many high-end cars are now equipped with electric suction doors, which can automatically close the door by operating a suction motor. During the door closing process, the system resistance is as high as 500N, so the self-closing motor needs to overcome 500N of system resistance to close the door. When the clamping force of the door reaches 100N, it will cause substantial damage to the user. Therefore, if a user's hand is caught in an electric suction door, it will cause even greater damage.

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

[0067] For the reasons mentioned above, such as Figure 1 and Figure 2 As shown, the present invention provides an anti-pinch device for an electric suction door, including a sealing strip 1 installed in the door gap between the front door 2 and the rear door 3. 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 both the front and rear doors 3 are closed, the sealing strip 1 can simultaneously abut against both the front door 2 and the rear door 3 to seal 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 rearward. The rear door edging 31 extends inward and forward along the inclined end face 32 of the rear door 3 to the inner side of the front door edging 21, thus creating a misalignment between the two. The front door edging 21 and the rear door edging 31 are arranged at intervals along the vehicle body from the outside to the inside. The front door edging 21, the rear door edging 31, and the inclined end face 32 together form a sealing cavity to accommodate the sealing strip 1, thus creating a door gap between the front door edging 21 and the inclined end face 32 that is easy to pinch.

[0069] The sealing strip 1 includes a connecting portion 13, a fixing portion 14, and a collapsible portion 15, which are joined end to end, making the cross-section of the sealing strip 1 annular. The connecting portion 13 is fitted and fixed to the outer side of the rear door edging 31, the fixing portion 14 is fitted and fixed to the inclined end face 32, and the collapsible portion 15 is fitted and abutted against the inner side of the front door edging 21. A first conductor 41 is disposed on the inner wall of the collapsible portion 15, and a second conductor 42 is disposed on the inner wall of the fixing portion 14, so that the first conductor 41 and the second conductor 42 are positioned opposite each other on both sides of the door gap, and the first conductor 41 can move with the deformation of the collapsible portion 15. Furthermore, as... Figure 3 As shown, the first conductor 41 and the second conductor 42, together with the vehicle's power supply 5, control module 6 and suction motor 7, form a control circuit.

[0070] Specifically, when the door closes to the final suction stage, the suction motor 7 starts running to drive the door to rotate inward. If no finger is 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 undergo large deformation. The collapsible part 15 will remain in contact with the inner side of the front door edge 21, ensuring a tight fit between the collapsible part 15 and the inner side of the front door edge 21 to guarantee 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, keeping the control circuit in a always open state.

[0071] If your finger gets caught in the door crack, such as Figure 2 As shown, the compression and collapse portion 15 will be squeezed and deformed inward. Correspondingly, the first conductor 41 will move inward with the deformation of the compression and collapse portion 15 and contact the second conductor 42 to conduct the control circuit, thereby controlling the suction motor 7 to stop or reverse, so that the door stops suction or reopens, avoiding substantial damage to the fingers.

[0072] Preferably, the distance between the first conductor 41 and the second conductor 42 under normal conditions is maintained between 5mm and 6mm. This distance should not be too far or too close. It should ensure that the deformation caused by the finger being pinched is sufficient to make the first conductor 41 and the second conductor 42 come into contact, while preventing the first conductor 41 and the second conductor 42 from making accidental contact due to normal vibration of the door.

[0073] like Figure 1 and Figure 2 As shown, in a preferred embodiment of the present invention, a first weakening part 11 is provided on the sealing strip 1 at the connection between the collapsible part 15 and the connecting part 13, and a second weakening part 12 is provided at the connection between the collapsible part 15 and the fixing part 14. The line connecting the first weakening part 11 and the second weakening part 12 is made nearly parallel to the fixing part 14 so that the collapsible part 15 can move toward the fixing part 14 when it is squeezed.

[0074] Specifically, such as Figure 1 As shown, when the hand is not caught, the collapsible part 15 is only subjected to inward pressure along the width direction of the vehicle body applied by the front door edge 21, and the pressure is small, which can only make the collapsible part 15 fit tightly against the inner side of the front door edge 21 to ensure good sealing between the two.

[0075] like Figure 2 As shown, when a hand is pinched, the fingers exert inward and backward pressure on the collapsible portion 15. Therefore, the first weakened portion 11 and the second weakened portion 12 are weakened to reduce their strength. They will deform first when subjected to pressure, so that the collapsible portion 15 can move along the direction perpendicular to the line connecting the first weakened portion 11 and the second weakened portion 12 after being squeezed. This ensures that the first conductor 41 can accurately contact the second conductor 42 to conduct the control circuit, 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 part 11 and the second weakened part 12. For example, the thickness of these two positions can be processed to be thinner than that of other positions, or a softer material can be used in these two positions than in other positions, etc. 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 to the protection scope of the present invention.

[0077] To further prevent accidental contact between the first conductor 41 and the second conductor 42 caused by normal system vibration, and to ensure reliable contact when a hand is pinched, such as Figure 1 and Figure 2 As shown, in this 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 strip with a certain width.

[0078] Furthermore, regarding the installation structure of the sealing strip 1 and the rear door 3, preferably, as follows: Figure 1 and Figure 2 As shown, a mounting groove 16 is provided on the connecting part 13, and the mounting groove 16 is clamped onto the rear door edge 31. This achieves a stable connection between the sealing strip 1 and the door body using a simple structure, reducing processing difficulty and controlling production costs.

[0079] Preferably, such as Figure 1 and Figure 2As shown, a reinforcing member 161 is also embedded in the mounting groove 16. The reinforcing member 161 is a groove-shaped structure adapted to the mounting groove 16 and is made of a relatively hard material, such as metal. It can support and shape the mounting groove 16, ensuring that the mounting groove 16 has a stable clamping force and preventing loosening later, which would affect the stable connection between the sealing strip 1 and the door body.

[0080] A raised structure 162 is also provided on the inner wall of the mounting groove 16. The raised structure 162 abuts against the rear door edge 31 and can press the rear door edge 31 tightly into the mounting groove 16. This achieves an interference fit between the rear door edge 31 and the mounting groove 16, 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] Furthermore, the vehicle provided by the present invention, based on the aforementioned anti-pinch device, possesses the technical effects of the aforementioned anti-pinch device due to the adoption of the aforementioned anti-pinch device. Compared with the vehicle before the improvement, the vehicle of the present invention improves the texture and safety of the door, thereby enhancing the sense of luxury.

[0082] Finally, as 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 injury to passengers caused by the electric suction door during the closing process.

[0083] The technical solution of the present invention has been described above with reference to the preferred embodiments shown in the accompanying drawings. However, it will be readily understood by those skilled in the art that the scope of protection of the present invention is obviously not limited to these specific embodiments. Without departing from the principles 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 such changes or substitutions will all fall within the scope of protection of the present invention.
