AI Technical Summary
Existing electric suction doors have problems with poor safety and high cost during the self-closing process. In particular, the use of high-precision sensors or motors leads to excessive costs, and it is difficult to effectively prevent pinching injuries.
An anti-pinch strip is used, including a first conductive part and a second conductive part. The electrical parameters are changed by the contact between the conductive parts when squeezed, which serves as an anti-pinch signal. The controller monitors the changes in electrical parameters and controls the self-priming motor to cut off power, replacing the high-precision sensor or motor.
This reduces the safety risks and costs associated with electric suction doors. By altering electrical parameters through conductive parts to provide an anti-pinch signal, the controller promptly cuts off power to prevent self-closing, thus achieving a balance between safety and cost.

[0015] Exemplary embodiments of the present disclosure are described herein with reference to the accompanying drawings, which are included to provide a further understanding of the present disclosure and are incorporated in and constitute a part of this specification, illustrate embodiments of the present disclosure and together with the description serve to explain the principles of the present disclosure. They should be considered in their entirety as illustrative of the present disclosure and not restrictive of the present disclosure. Accordingly, those of ordinary skill in the art will recognize that the embodiments described herein can be varied and modified and will realize, based on the teachings set forth herein, the spirit and scope of the present disclosure. As well, those of ordinary skill in the art will embrace modifications appropriate to particular applications and the hereto equivalent structures and functions, and the terms described herein are used for descriptive purposes only and not limiting.
[0016] Figure 1 is a structure diagram of a car door anti-pinch strip according to one embodiment of the present disclosure, Figure 2 is a structure diagram of a car door anti-pinch strip according to one embodiment of the present disclosure.
[0017] As shown in Figure 1 and Figure 2 , the car door anti-pinch strip (hereinafter referred to as anti-pinch strip) includes a first conductive part 11, a second conductive part 12 and a resistance part, the first conductive part 11 or the second conductive part 12 is electrically connected with the resistance part, there is a gap between the first conductive part 11 and the second conductive part 12, when the first conductive part 11 is pressed, the first conductive part 11 and the second conductive part 12 are in contact, so that the resistance value of the anti-pinch strip changes.
[0018] The first conductive part 11 and the second conductive part 12 are both parts for conducting electricity in the anti-pinch strip, and the first conductive part 11 and the second conductive part 12 can be electrically connected with the power supply to make the anti-pinch strip conduct electricity.
[0019] The resistance part includes a resistor, and the first conductive part 11 or the second conductive part 12 is electrically connected with the resistance part. When the first conductive part 11 is not extruded, there is a gap between the first conductive part 11 and the second conductive part 12, so that the first conductive part 11 and the second conductive part 12 do not form a loop, and the resistance value of the anti-pinch strip is equal to the resistance value of the resistance part; when the first conductive part 11 is extruded, the first conductive part 11 is in contact with the second conductive part 12, the first conductive part 11 and the second conductive part 12 are connected in parallel, and the resistance part is short-circuited, so that the electrical parameter of the anti-pinch strip changes. As an example: if the second conductive part 12 is electrically connected with the resistance part, when the first conductive part 11 is in contact with the second conductive part 12, the first conductive part 11 is short-circuited, so that the resistance part is short-circuited, so that the electrical parameter changes.
[0020] In the related art of the present disclosure, the anti-pinch of the automatic door and the electric suction door usually needs to be realized based on an anti-pinch signal. The automatic door is a door that can automatically open and close, and the electric suction door is a door that can be automatically sucked to the fully locked position when it is closed to the half-locked position. At present, high-precision sensors or high-precision motors usually need to be arranged in the automatic door area and the electric suction door area to provide an anti-pinch signal in the case that foreign matter is extruded between the door gaps. However, the cost of high-precision sensors and high-precision motors is usually high. In order to solve the problems in the related art, in the embodiments of the present disclosure, the anti-pinch strip can be used for anti-pinch of the automatic door and the electric suction door, and the anti-pinch strip can be arranged in the door gap area. In general, the first conductive part 11 of the anti-pinch strip will not be extruded; when the door is in a gradually closing state, and foreign matter is located in the door gap area and extrudes the first conductive part 11, the first conductive part 11 is in contact with the second conductive part 12, so that the electrical parameter of the anti-pinch strip changes, and the change of the electrical parameter of the anti-pinch strip can be used as an anti-pinch signal. It can be seen that the anti-pinch signal is provided by the anti-pinch strip in the embodiments of the present application, which can save costs compared with the related art of providing an anti-pinch signal by high-precision sensors or high-precision motors.
[0021] In order to more clearly understand the conductive part of the embodiments of the present disclosure, the structure of the first conductive part 11 and the second conductive part 12 is exemplarily described below.
[0022] As Figure 1 and Figure 2As shown, the first conductive part 11 can include a first conductive wire 111 and a first conductive glue 112, and the first conductive glue 112 wraps the first conductive wire 111; the second conductive part 12 can include a second conductive wire 121 and a second conductive glue 122, and the second conductive glue 122 wraps the second conductive wire 121. The first conductive wire 111 or the second conductive wire 121 is connected with the resistance part of the anti-pinch strip. When the first conductive part 11 is not extruded, there is a gap between the first conductive glue 112 and the second conductive glue 122, and the first conductive wire 111 and the second conductive wire 121 do not form a loop; when the first conductive part 11 is extruded, the first conductive glue 112 and the second conductive glue 122 are in contact, so that the first conductive wire 111 and the second conductive wire 121 form a loop, and the conductive wire of the first conductive wire 111 and the second conductive wire 121 which is not connected with the resistance part is short-circuited, and the resistance part is short-circuited, so that the electrical parameter of the anti-pinch strip changes. It should be noted that the first conductive glue 112 can be protruded towards the second conductive glue 122, or the second conductive glue 122 can be protruded towards the first conductive glue 112, so that when the first conductive part 11 is extruded, the first conductive glue 112 and the second conductive glue 122 can be in contact in time.
[0023] It should be noted that for the first conductive part, if the first conductive part 11 is extruded on one side and is provided with a soft material fixed thereto, the material of the first conductive part 11 can be a soft material or a hard material, and the soft material fixed with the first conductive part 11 is extruded to extrude the first conductive part 11, so that the first conductive part 11 is in contact with the second conductive part 12, wherein the material of the first conductive part 11 is a soft material, which can further reduce the harm to the human body; if the first conductive part 11 is extruded on one side and is not provided with a soft material fixed thereto, the material of the first conductive part 11 can be a soft material, so that the first conductive part 11 can be in contact with the second conductive part 12 under extrusion. For the second conductive part 12, the material of the second conductive part 12 can be a soft material or a hard material, and the material of the second conductive part is a soft material, which can further reduce the harm to the human body.
[0024] By the above arrangement, when the first conductive part of the anti-pinch strip is pressed, the first conductive part and the second conductive part are in contact, so that the electrical parameter of the anti-pinch strip changes. The change in the electrical parameter of the anti-pinch strip can be used as an anti-pinch signal. The anti-pinch strip of the embodiment of the present disclosure can replace the anti-pinch device in the related art, such as a high-precision sensor or a high-precision motor, thereby facilitating cost savings. The electric suction door includes an electric suction vehicle door. When the electric suction vehicle door is closed to a half-lock position (the half-lock position can also be referred to as a first gear lock position), a self-suction motor can be triggered to perform a self-suction action to suction the vehicle door from the half-lock position to a full-lock position (the full-lock position can also be referred to as a second gear lock position). At present, a part of the electric suction vehicle door does not set an anti-pinch strategy. During the self-suction action performed by the self-suction motor, if a finger or other part of the human body is located at a door gap of the electric suction vehicle door, the self-suction motor will continue to perform the self-suction action, which leads to poor safety of the electric suction vehicle door and is easy to be pinched by the electric suction vehicle door. Another part of the self-suction motor sets an anti-pinch strategy, which usually uses a high-precision motor or a current sensor to monitor a weak current change, thereby achieving door anti-pinch. However, the use of a high-precision motor or a current sensor will lead to high cost.
[0025] It can be seen that the electric suction vehicle door has a problem of difficult trade-off between safety and cost.
[0026] To solve the above problem, in the embodiment of the present disclosure, the anti-pinch strip can be arranged at the edge of at least one vehicle door and / or the edge of at least one vehicle door frame. The anti-pinch strip can be connected to a vehicle power supply and connected to a controller. The controller can monitor the electrical parameter of the anti-pinch strip and control the self-suction motor of the door lock to be powered off when the electrical parameter of the anti-pinch strip changes. By such an arrangement, if a finger or other part of the human body is located at a door gap of the electric suction vehicle door, as the self-suction motor performs a self-suction action, the finger or other part of the human body will press the first conductive part 11. When the first conductive part 11 and the second conductive part 12 are in contact, the resistance value of the anti-pinch strip sharply decreases, thereby causing the electrical parameter (current, voltage, or resistance) of the anti-pinch strip to change. When the controller detects that the electrical parameter of the anti-pinch strip changes, the self-suction motor can be controlled to be powered off to avoid the self-suction motor continuing to perform the self-suction action, thereby reducing the risk of being pinched by the self-suction motor. Compared with the high-precision motor or the current sensor, the anti-pinch strip in the embodiment of the present disclosure has lower cost, thereby the embodiment of the present disclosure can balance the safety and cost of the vehicle door.
[0027] In the embodiments of the present disclosure, when the first conductive part 11 of the door anti-pinch strip is pressed, the first conductive part 11 and the second conductive part 12 are in contact, so that the resistance value of the anti-pinch strip changes; the anti-pinch strip can be electrically connected to the controller, and the controller can monitor the change of the electric parameter of the anti-pinch strip when the resistance value of the anti-pinch strip changes. The controller controls the door lock self-suction motor to be powered off when the electric parameter of the anti-pinch strip changes, so as to avoid the door lock self-suction motor from sucking the door to the full lock position, thereby improving the safety of the door and reducing the risk of being pinched by the door. Compared with high-precision motors or current sensors, the cost of the anti-pinch strip in the embodiments of the present disclosure is lower, so that the safety and cost of the door can be considered in the embodiments of the present disclosure.
[0028] In some embodiments, the first conductive part 11 is configured to be in contact with the second conductive part 12 when the minimum pressing force received is in the range of 5N to 25N.
[0029] In the embodiments of the present disclosure, it is not limited that the first conductive part 11 is configured to be in contact with the second conductive part only when a specific amount of pressure is received. As long as the first conductive part 11 is configured to be in contact with the second conductive part 12 when the minimum pressing force received is in the range of 5N to 25N, which is conducive to improving the flexibility of the configuration of the first conductive part. For example, the first conductive part 11 can be configured to be in contact with the second conductive part 12 when the minimum pressing force received is 5N. For another example, the first conductive part 11 can be configured to be in contact with the second conductive part 12 when the minimum pressing force received is 15N.
[0030] For example, the flexibility of the first conductive part 11 can be set so that the first conductive part 11 is in contact with the second conductive part 12 when the minimum pressing force received is in the range of 5N to 25N. For another example, the anti-pinch strip can be arranged inside the door weather strip (the weather strip can also be referred to as a sealing strip), and the flexibility of the weather strip can be set so that the first conductive part 11 is in contact with the second conductive part 12 when the minimum pressing force received is in the range of 5N to 25N.
[0031] For example, a 4mm diameter metal rod can be used to simulate a finger, and the flexibility of the first conductive part 11 can be adjusted through experiments, or when the anti-pinch strip is arranged inside the door weather strip, the flexibility of the weather strip can be adjusted, so that the first conductive part 11 is in contact with the second conductive part 12 when the 4mm metal rod is pressed on the first conductive part 11 with a minimum pressing force in the range of 5N to 25N.
[0032] According to human mechanics, the weakest finger and its soft tissues will not be bruised when a pressure less than 25N is applied. In the embodiment of the present disclosure, the first conductive part 11 is configured to be in contact with the second conductive part 12 when the minimum extrusion force applied thereto is in the range of 5N to 25N, that is, when the minimum extrusion force applied to the first conductive part 11 is in the range of 5N to 25N, the electrical parameter of the anti-pinch strip changes, and the controller controls the self-suction motor to be powered off. By such an arrangement, when the finger or other part of the human body is at the door gap during the self-suction operation of the door lock self-suction motor, and a pressure in the range of 5N to 25N is applied to the first conductive part 11 of the door or the door frame, the controller can control the self-suction motor to be powered off in time, so as to avoid the self-suction motor continuing to perform the self-suction operation and causing a pressure greater than 25N to the finger or other part of the human body, thereby further reducing the risk of being pinched by the door.
[0033] It is considered that there may be a situation that during the self-suction operation of the door lock self-suction motor, a soft object may be at the door gap, and the soft object may apply a pressure less than 5N to the first conductive part 11 as the door is closed. In this case, the door lock self-suction motor self-suctioning the door from the half-lock position to the full-lock position will not cause injury to the human body. Based on this, in the embodiment of the present disclosure, the first conductive part 11 is configured such that when the extrusion force applied thereto is less than 5N, there is still a gap between the first conductive part 11 and the second conductive part 12, and the resistance value of the anti-pinch strip does not change, and the door lock self-suction motor is continuously powered on.
[0034] The embodiment of the present disclosure can further reduce the risk of being pinched by the door by configuring the first conductive part 11 to be in contact with the second conductive part 12 when the minimum extrusion force applied thereto is in the range of 5N to 25N.
[0035] The embodiment of the present disclosure also provides a door anti-pinch device (hereinafter referred to as anti-pinch device) comprising a controller and any one of the anti-pinch strips of the embodiments of the present disclosure, the controller being electrically connected to the anti-pinch strip.
[0036] The controller is configured to control the door lock self-suction motor of the door to be powered off when the electrical parameter of the anti-pinch strip changes.
[0037] The controller can be a controller specially provided for the anti-pinch device, or the controller can be an existing controller of the vehicle, such as a body control module (BCM), a door control module (DCM), or a door lock control module.
[0038] The anti-pinch strip can be electrically connected to the vehicle's power supply to energize it. A controller is also electrically connected to the anti-pinch strip to monitor its electrical parameters, such as resistance, current, or voltage. The controller can also be connected to the door's automatic door lock motor to de-energize the motor when the anti-pinch strip's electrical parameters change.
[0039] It should be noted that the controller can be electrically connected to one or multiple anti-pinch strips. The number of anti-pinch strips can be set according to the number of door lock self-closing motors, with one anti-pinch strip corresponding to one door lock self-closing motor. When the controller is connected to multiple anti-pinch strips, it can detect the electrical parameters of each strip and, if the electrical parameters of any of the strips change, de-energize the door lock self-closing motor corresponding to that strip.
[0040] To better understand the anti-pinch strategy of the embodiments of this disclosure, the following description is provided in conjunction with specific examples.
[0041] Assuming the vehicle includes two doors (a left door and a right door), a left door lock self-closing motor is installed in the left door area, and a right door lock self-closing motor is installed in the right door area. In this embodiment, the number of anti-pinch strips can be set to two, one for the left side and one for the right side. The left anti-pinch strip is deployed in the left door seam area and corresponds to the left door lock self-closing motor; the right anti-pinch strip is deployed in the right door seam area and corresponds to the right door lock self-closing motor. If the electrical parameters of the left anti-pinch strip change, the controller can de-energize the left door lock self-closing motor; similarly, if the electrical parameters of the right anti-pinch strip change, the controller can de-energize the right door lock self-closing motor.
[0042] like Figure 3 As shown, in some embodiments, the anti-pinch device further includes a protective resistor 2, and the anti-pinch strip 1 is electrically connected to the vehicle's power supply through the protective resistor 2.
[0043] By connecting the anti-pinch strip to the vehicle's power supply, there is no need to set up a separate power supply for the anti-pinch strip. Sharing the vehicle's power supply with the anti-pinch strip helps save costs.
[0044] Considering that the anti-pinch strip 1 is directly connected to the vehicle's power supply, which may pose a potential safety risk, this embodiment of the disclosure sets the anti-pinch strip 1 to be electrically connected to the vehicle's power supply through a protective resistor 2. The protective resistor 2 has a voltage divider effect; setting the protective resistor can reduce the voltage of the anti-pinch strip accordingly, thereby improving the safety of the anti-pinch strip.
[0045] It should be noted that in the case that the anti-pinch device has a plurality of anti-pinch strips 1, a plurality of protection resistors 2 can be provided, or one protection resistor 2 can be provided. If a plurality of protection resistors 2 are provided, each anti-pinch strip 1 can be electrically connected to the power supply of the vehicle through a corresponding protection resistor 2; if one protection resistor 2 is provided, the plurality of anti-pinch strips 1 can be electrically connected to the power supply of the vehicle through the same protection resistor 2.
[0046] For example, if the resistance value of the protection resistor 2 is equal to the resistance value of the resistance part, and assuming that the protection resistor 2 is electrically connected to only one anti-pinch strip 1, and the rated voltage of the vehicle power supply is 24V. In the case that the first conductive part 11 and the second conductive part 12 of the anti-pinch strip 1 are not in contact, the resistance value of the anti-pinch strip 1 is equal to the resistance value of the resistance part, the voltage of the protection resistor 2 is 12V, and the voltage of the anti-pinch strip 1 is also 12V. In the case that the human body contacts the voltage of 12V, the human body is usually not injured.
[0047] In the embodiments of the present disclosure, the anti-pinch strip 1 is electrically connected to the protection resistor 2, so that the protection resistor 2 can divide the voltage to reduce the voltage of the anti-pinch strip 1, thereby improving the safety of the anti-pinch device.
[0048] In some embodiments, the resistance value of the protection resistor 2 is greater than or equal to the resistance value of the resistance part of the anti-pinch strip 1.
[0049] It is easy to understand that the anti-pinch strip 1 is electrically connected to the power supply of the vehicle through the protection resistor 2, and the power supply of the vehicle is usually a constant voltage power supply. The greater the resistance value of the protection resistor 2 is relative to the resistance value of the anti-pinch strip 1, the higher the voltage of the protection resistor 2 is, and the smaller the voltage of the anti-pinch strip 1 is. In the embodiments of the present disclosure, the resistance value of the protection resistor 2 is greater than or equal to the resistance value of the resistance part of the anti-pinch strip 1. Thus, the safety of the anti-pinch strip 1 can be further improved.
[0050] In the embodiments of the present disclosure, the anti-pinch strip 1 is connected to the power supply of the vehicle through the protection resistor 2, and the power supply of the vehicle is usually a constant voltage power supply. When the first conductive part 11 and the second conductive part 12 of the anti-pinch strip 1 are in contact, the first conductive part 11 and the second conductive part 12 form a conductive loop, thereby causing the resistance part of the anti-pinch strip 1 to be short-circuited, causing the resistance value of the anti-pinch strip 1 to decrease, and causing the voltage and current of the anti-pinch strip 1 to change accordingly. The controller of the present disclosure can control the door lock self-suction motor to be powered off when the current, resistance or voltage of the anti-pinch strip 1 changes.
[0051] In some embodiments, the controller can be a controller provided with a resistance monitoring module, so that the controller can monitor the resistance value of the anti-pinch strip 1, and can control the door lock self-suction motor to be powered off when the resistance value of the anti-pinch strip 1 decreases.
[0052] In some other embodiments, the controller can be a controller provided with a current monitoring module, so that the controller can monitor the current value of the anti-pinch strip 1. As can be easily understood, when the first conductive part is in contact with the second conductive part, the first conductive part and the second conductive part form a conductive loop, causing the resistance part to be short-circuited, and thus causing the current value of the anti-pinch strip 1 to increase. In the case where the current value of the anti-pinch strip 1 increases, the controller of the embodiments of the present disclosure can control the door lock self-suction motor to be powered off.
[0053] It is considered that the cost of the resistance monitoring module is generally high, and the provision of the resistance detection module in the controller will increase the cost of the controller. In order to protect the safety of the human body, the current value of the anti-pinch strip 1 is usually in the order of milliamperes, and the current value in the order of milliamperes is usually difficult to monitor. In actual application, even if the resistance part of the anti-pinch strip 1 is short-circuited, the current value change rate of the anti-pinch strip 1 is usually small.
[0054] Based on the above circumstances, the present disclosure also provides another embodiment, in which the controller is connected in parallel with the anti-pinch strip 1, and the controller is used to control the door lock self-suction motor of the vehicle door to be powered off when the voltage of the anti-pinch strip 1 decreases.
[0055] The controller is connected in parallel with the anti-pinch strip 1, and the controller can be provided with a voltage monitoring module to monitor the voltage of the anti-pinch strip 1. When the first conductive part 11 of the anti-pinch strip 1 is in contact with the second conductive part 12, the resistance value of the anti-pinch strip 1 decreases significantly, thereby causing the voltage of the anti-pinch strip 1 to decrease significantly.
[0056] As an example: assuming that the protection resistance 2 is only electrically connected with one anti-pinch strip 1, and the rated voltage of the vehicle is 24V, in the case where the first conductive part 11 and the second conductive part 12 of the anti-pinch strip 1 are not in contact, the resistance value of the anti-pinch strip 1 is equal to the resistance value of the resistance part, the voltage of the protection resistance 2 is 12V, and the voltage of the anti-pinch strip 1 is also 12V; in the case where the first conductive part 11 and the second conductive part 12 of the anti-pinch strip 1 are in contact, the resistance part is short-circuited, causing the resistance of the anti-pinch strip 1 to decrease from 500Ω to less than 100Ω, thereby causing the voltage of the protection resistance to increase to more than 20V, and the voltage of the anti-pinch strip 1 to decrease to less than 4V.
[0057] In the embodiments of the present disclosure, the controller is connected in parallel with the anti-pinch strip, and the controller is used to monitor the voltage of the anti-pinch strip. On the one hand, compared with the resistance monitoring module, the cost of the voltage monitoring module is lower, and the controller of the embodiments of the present disclosure can be provided with a voltage monitoring module to realize the voltage monitoring of the anti-pinch strip, thereby saving the cost of the anti-pinch device. On the other hand, when the resistance value of the anti-pinch strip changes, the current of the anti-pinch strip only changes slightly. Compared with monitoring whether the current of the anti-pinch strip changes, the controller can more timely monitor whether the voltage of the anti-pinch strip changes, so that the controller can timely control the door lock self-suction motor to be powered off.
[0058] In some embodiments, the resistance value of the protection resistor 2 is equal to the resistance value of the anti-pinch strip 1. By setting the resistance value of the protection resistor 2 equal to the resistance value of the anti-pinch strip 1, the protection resistor 2 will not excessively divide the voltage, so that the voltage of the anti-pinch strip 1 is too small, and thus the controller can more easily monitor the voltage change of the anti-pinch strip 1.
[0059] The embodiments of the present disclosure also provide a vehicle door, which comprises a vehicle door body and any one of the anti-pinch devices of the embodiments of the present disclosure.
[0060] Any one of the anti-pinch devices of the embodiments of the present disclosure can be applied to the vehicle door in the embodiments of the present disclosure, and can achieve the same technical effects. To avoid repetition, details are not described here.
[0061] The embodiments of the present disclosure also provide a vehicle, at least one door and / or at least one door frame of the vehicle are provided with any one of the anti-pinch devices of the embodiments of the present disclosure.
[0062] In the embodiments of the present disclosure, the vehicle includes a non-autonomous vehicle and an autonomous vehicle.
[0063] At least one door and / or at least one door frame of the vehicle is provided with the anti-pinch device, specifically, at least one door and / or at least one door frame of the vehicle is provided with the anti-pinch strip of the anti-pinch device. For example, in the case that the vehicle includes four doors, in order to make the anti-pinch strips arranged in a more concentrated position, the anti-pinch strips of the anti-pinch device can be arranged on the door frames of the front doors, and the anti-pinch strips of the anti-pinch device can be arranged on the door frames of the rear doors. For another example, in order to further reduce the risk of being pinched by the door, the anti-pinch strips can be arranged on the door frames corresponding to the rear doors. In this way, as the door lock self-suction motor self-sucks, if the fingers or other parts of the human body are located at the gap of the rear door, the anti-pinch strips of the rear door and the rear door frame will be squeezed, rather than the metal of the rear door or the rear door frame, thereby further reducing the risk of being pinched by the door.
[0064] In some embodiments, the vehicle includes a first door lock self-suction motor and a second door lock self-suction motor, the first door lock self-suction motor is arranged on the front door, and the second door lock self-suction motor is arranged on the rear door.

[0066] The controller is configured to: control the first door lock self-suction motor to be powered off when the electrical parameter of the first anti-pinch strip changes, and control the second door lock self-suction motor to be powered off when the electrical parameter of the second anti-pinch strip changes.
[0067] The first door lock self-suction motor can be a door lock self-suction motor arranged in the left front door or the right front door.
[0068] The first anti-pinch strip is arranged at the front edge of the rear door, and the front edge of the rear door is the edge of the rear door close to the front direction of the vehicle. The first anti-pinch strip corresponds to the first door lock self-suction motor. If the first door lock self-suction motor is a door lock self-suction motor arranged in the left front door, the first anti-pinch strip is a door lock self-suction motor arranged at the front edge of the left rear door. If the first door lock self-suction motor is a door lock self-suction motor arranged in the right front door, the first anti-pinch strip is a door lock self-suction motor arranged at the front edge of the right rear door.
[0069] The second anti-pinch strip is arranged at the rear edge of the rear door, and the rear edge of the rear door is the edge of the rear door close to the rear direction of the vehicle. The second anti-pinch strip corresponds to the second door lock self-suction motor. If the second door lock self-suction motor is a door lock self-suction motor arranged in the left rear door, the second anti-pinch strip is a door lock self-suction motor arranged at the rear edge of the left rear door. If the second door lock self-suction motor is a door lock self-suction motor arranged in the right rear door, the first anti-pinch strip is a door lock self-suction motor arranged at the rear edge of the right rear door.
[0070] According to the above arrangement, the anti-pinch device of the rear door can realize both the front door anti-pinch function and the rear door anti-pinch function. By arranging the first anti-pinch strip and the second anti-pinch strip on the rear door, the anti-pinch strips are more concentrated, thereby reducing the complexity of electrical connection between the anti-pinch strips and the controller.
