Detailed Description
Exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. While exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be embodied in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art.
As shown in fig. 1, 2, 4, and 5, an embodiment of the invention provides a method for preventing a door from being pinched, the method including:
step 101, judging whether the vehicle door 2 is in a closing process;
step 102, if the vehicle door 2 is in a closing process, detecting whether an object exists between the vehicle door 2 and a vehicle door frame (not shown in the figure) through a resistance type pressure position sealing strip 1 arranged on the vehicle door 2;
in step 103, if an object exists, the door 2 is prevented from being closed by a door closing stopper mechanism (not shown).
Preferably, the specific implementation manner of step 101 may be to determine whether the door 2 is in the closing process according to an opening angle of the door 2 (here, the opening angle is an included angle formed by the door 2 and the vehicle body 3, such as an included angle β in fig. 5).
In practical applications, the determining whether the vehicle door 2 is in the closing process according to the opening angle of the vehicle door 2 (which can be obtained by the vehicle door opening sensor) may specifically be: if the angle variation corresponding to the opening angle is less than 0, the vehicle door 2 is in the closing process, otherwise, the vehicle door 2 is not in the closing process. Namely, whether the vehicle door 2 is in the closing process is judged by judging the variation trend of the opening angle: if the amount of change in the angle thereof is small by 0, it is interpreted that the angle of the opening angle tends to become small, and thus it can be determined that the door 2 is in the process of closing (i.e., the door 2 is closing); otherwise, it can be determined that the vehicle door 2 is not in the closing process (which can be understood as being in the closed state or in the opening process, at which time it is not necessary to perform a preventive treatment).
Preferably, as shown in fig. 4, the resistive pressure position sealing strip 1 is installed inside the door 2 and wraps around the inside of the door 2 (i.e. it is equivalent to installing the resistive pressure position sealing strip 1 wrapped around the inside of the door 2). As shown in fig. 2, the resistive pressure position seal 1 includes: the resistor comprises a resistor outer film 11, a resistor inner film 12 integrally connected with the resistor outer film 11 and a resistor strip 13 arranged corresponding to the resistor inner film 12, wherein the resistor outer film 11 pushes the resistor inner film 12 to be in contact with and conducted with the resistor strip 13 under the action of pressure.
In step 102, one implementation manner of detecting whether an object exists between the vehicle door 2 and the vehicle door frame by using the resistive pressure position sealing strip 1 installed on the vehicle door 2 may be:
102A, the length L can be determined according to the first length0A second length LαAnd Δ α, detecting whether an object exists between the door 2 and the door frame. Here, the first length L0The second length L is the length from a preset starting point (for example, point D in FIG. 2) to the contact point of the inner resistance film 12 and the resistance strip 13 on the sealing strip 1 at the resistance pressure positionαThe preset length corresponding to the opening angle = α of the door 2 (it can be understood that, if there is no obstacle between the door 2 and the door frame when the opening angle of the door 2 is α, the length is the preset length corresponding to the opening angle = α of the door 2 (it can be understood that, if there is no obstacle between the door 2 and the door frame, the length is the preset length)The normal length from a preset starting point to the contact point between the inner resistance film 12 and the resistance strip 13 on the sealing strip 1 at the resistance pressure position), Δ α is the corresponding angle variation when the opening angle of the vehicle door 2 = α.
As shown in fig. 3, the first length L0The calculation can be derived by the following formula:
1)
Figure BDA0002419498600000061
2)
Figure BDA0002419498600000062
3)
Figure BDA0002419498600000063
that is, formula 3) can be derived from formula 1) and formula 2), that is, L can be obtained0。
Wherein L is the length of the resistive pressure position sealing strip 1, R0The length from a starting point to a contact point between the inner resistance film 12 and the resistance strip 13 on the resistance pressure position sealing strip 1 is represented by R, U, and I, where R is a resistance value of the inner resistance film 12, U is a voltage value applied to the inner resistance film 12, and I is a current value conducted in the inner resistance film 12.
In practical applications, the step 102A may specifically include:
step 102A1, if the first condition cannot be satisfied simultaneously: "L0Varying in a predetermined order, L0＝LαAnd Δ α<0', then it is determined whether the second condition can be satisfied simultaneously: "L0Varying in a predetermined order, L0＝LαAnd Δ α>0". That is, in the normal condition (i.e. when there is no obstacle between the door 2 and the door frame), the contact process between the resistive pressure position weather strip 1 on the door 2 and the door frame during the closing process of the door 2 is as follows (see fig. 4): in the order of A (a) -B (B) -C (C) -D (point A and point a are located above and below the door hinge 21, respectively, as shown in FIG. 4) (which may be considered a predetermined order), so that if L is0Change in a predetermined order (illustrating resistance)The contact sequence of the sealing strip 1 and the door frame of the car at the formula pressure position is normal), and L0＝Lα(Note that there is no object obstruction between the door 2 and the door frame because L if an object is present0Must be linked with LαDifferent), and Δ α<0 (indicating that the vehicle door 2 is being closed), it indicates that there is no object (obstacle) in the closing process of the vehicle door 2, otherwise, it can be preliminarily determined that there is an object in the closing process of the vehicle door 2, so that it is necessary to continue to determine the second condition for further confirmation, that is, if L is0Change according to a predetermined sequence (which shows that the contact sequence of the sealing strip 1 and the door frame of the car at the resistance pressure position is normal), and L0＝Lα(No physical obstruction between the door 2 and the door frame is described), and Δ α>0 (indicating that the door 2 is being opened).
Step 102A2, if the second condition cannot be satisfied at the same time, it is determined that an object exists between the vehicle door 2 and the vehicle door frame. That is, if L does not satisfy the first condition0Not varying in a predetermined order, or L0Is not equal to LαOr Δ α<=0, it can be confirmed that an object is present between the door 2 and the door frame during the closing of the door 2.
From the above, the purpose of detecting whether there is an object (no matter whether it is a living object) between the vehicle door 2 and the vehicle door frame can be conveniently and rapidly realized through the resistance type pressure position sealing strip 1 installed on the vehicle door 2 in the present embodiment, and the cost of the resistance type pressure position sealing strip 1 is relatively low and the arrangement and installation are convenient.
In step 103, one implementation manner of preventing the vehicle door 2 from being closed by the vehicle door closing limiting mechanism includes: step 103A, a control command for preventing the door 2 from closing is sent to the electromagnetic valve of the door closing limiting mechanism. That is, when it is detected that an object (i.e., an obstacle) is encountered during the closing of the door 2, a control command (signal) for preventing the door 2 from being closed may be sent to the electromagnetic valve of the door closing stopper mechanism.
And 103B, controlling the electromagnetic valve to close through the control command so as to prevent the vehicle door 2 from closing. Namely, the electromagnetic valve is closed (power off) under the control of the control instruction, and the vehicle door 2 is stopped (or delayed) to be closed under the limit action of closing the electromagnetic valve, so that the aim of preventing the vehicle door from being clamped is fulfilled.
According to the anti-pinch processing method for the vehicle door, the function of detecting whether an object exists between the vehicle door 2 and the vehicle door frame or not in the closing process of the vehicle door 2 is achieved through the resistance type pressure position sealing strip 1 arranged on the vehicle door 2, and the function of preventing (or delaying) the vehicle door 2 from being closed when the object exists between the vehicle door 2 and the vehicle door frame is achieved, so that the better anti-pinch purpose of the vehicle door is achieved. Resistance-type pressure position sealing strip 1 has the installation and arranges simple and convenient, the lower advantage of cost to no matter be life object all can detect, therefore overcome among the prior art adopt limbs detector, infrared sensor etc. to carry out the door when preventing pressing from both sides arrangement structure complicated, the cost is on the high side and can't detect the problem of non-life object.
