[0002] With the higher pursuit of users for driving and riding quality, more usage scenarios and requirements of vehicles are explored. For example, when outdoors on a rainy day, people need to hold an umbrella when getting out of a household car.

[0003] In the related art, there has emerged a structure that can drive a gear through a door driving motor on a rainy day to unfold a rain shield. However, it has the following problems:

[0004] When the car door is opened and the rain shield moves synchronously with the car door, the main link of the rain shield needs to be moved by another motor to engage with the gear driven by the door driving motor for transmission; when only the car door is opened, the other motor does not move the main link of the rain shield; although it can achieve the function of unfolding on a rainy day and retracting on a non-rainy day, its structure is relatively complex, that is, an additional motor is required to move the main link of the rain shield, which leads to an increase in manufacturing cost.

[0043] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the following will clearly and completely describe the technical solutions in the embodiments of this application with reference to the accompanying drawings in the embodiments of this application. Obviously, the described embodiments are some, but not all, of the embodiments of this application. All other embodiments obtained by those of ordinary skill in the art based on the embodiments in this application without creative efforts shall fall within the scope of protection of this application.

[0044] In the related art, the working principle of the rain shield is as follows:

[0045] Step 1: When the rain sensor senses rain, it transmits a signal to the controller. The controller issues an instruction to start the motor, which drives the main link of the rain shield downward to engage with the rain shield gear.

[0046] Step 2: When the door drive motor receives an opening instruction, it drives the door drive gear to move to the right. The door gear rotates clockwise, and the main link of the door rotates clockwise to open the door.

[0047] Step 3: When the door drive gear moves to the right, it simultaneously drives the rain shield gear to rotate counterclockwise, and the main link of the rain shield rotates counterclockwise to open the rain shield.

[0048] Step 4: When the door is closed, Steps 2 and 3 are repeated. The door and the rain shield rotate in opposite directions, and the rain shield is closed while the door is closed.

[0049] Step 5: When the rain sensor does not sense rain, it transmits a signal to the controller. The controller issues an instruction to start the motor, which drives the main link of the rain shield upward to disengage from the rain shield gear. At this time, the rain shield will not open when the door is opened.

[0050] The above structure is relatively complex, that is, an additional motor is required to move the main link of the rain shield, which increases the manufacturing cost. That is, the output power of the door drive motor also needs to be increased.

[0051] In addition, in order to avoid affecting the normal opening and closing of the door, the rain shield mechanism needs to be stored and hidden at the vehicle door lintel. However, the installation space at the vehicle door lintel is small, and it is difficult to effectively install the rain shield mechanism with a complex structure, and it has a certain impact on the layout of the vehicle body.

[0052] To solve the above problems, a vehicle door rain shield and its control method are proposed to solve the problem that the main link of the rain shield in the related art needs to be moved by a motor other than the door drive motor, and the structure of the solution for controlling the rain shield by engaging or disengaging with the gear driven by the door drive motor is complex, resulting in difficulty in installation in a limited space.

[0053] Please refer to Figure 1, in a first aspect, a car door rain curtain is provided, which includes:

[0054] A rolling curtain folding frame 1, on which a flexible shielding curtain 2 is provided, and one end of which is used to connect to the roof side beam, and the other end has a top support connection part;

[0055] A telescopic top rod 3, one end of which is used to be hinged to the roof side beam, and the other end is hinged to the top support connection part; the line connecting the two ends of the telescopic top rod 3 and the roof side beam has a designed included angle;

[0056] A controller 4, which is connected to the telescopic top rod 3; the controller 4 is used to control the expansion and contraction of the telescopic top rod 3 to drive the rolling curtain folding frame 1 to unfold or contract, and at the same time, the telescopic top rod 3 rotates around the hinge point hinged to the roof side beam. The controller 4 is a vehicle ECU or other CPU units with control functions.

[0057] The above cancels the structure of the cooperation between the motor and the gear. Only by the expansion and contraction of the telescopic top rod 3 can the rolling curtain folding frame 1 be unfolded or contracted, which simplifies the structure, facilitates installation in the limited space of the roof side beam, and also reduces the cost.

[0058] For the principle of only relying on the telescopic top rod 3 to cooperate with the rolling curtain folding frame 1 to unfold the flexible shielding curtain 2, reference can be made to Figure 2 、 Figure 3 and Figure 4 , specifically as follows:

[0059] Referring to Figure 4 , it shows that in the initial contracted state of the telescopic top rod 3, it is received in the accommodation space of the roof side beam at a certain angle, and the contraction states of the respective frames of the rolling curtain folding frame 1 in the initial contracted state; when the telescopic top rod 3 extends, it will generate a top support force F, and the top support force F acting on the top support connection part will generate component forces F1 and F2. Since the connections at both ends of the telescopic top rod 3 are hinged, the rolling curtain folding frame 1 will be driven to unfold under the action of the component force F2. At the same time of unfolding, the telescopic top rod 3 is driven to rotate. Reference can be made to the simplified schematic diagram of the principle from the initial contracted state to the final opened state in Figure 4 for comparison.

[0060] Among them, when the telescopic top rod 3 is in the initial contracted state, there is a certain included angle between it and the roof side beam, which ensures that the top support force F will be decomposed, facilitating the unfolding of the rolling curtain folding frame 1; if it is parallel to the roof side beam, it is difficult to effectively generate the component force F2 and difficult to drive the rolling curtain folding frame to unfold. The two ends of the telescopic top rod 3 do not need to specifically distinguish which end is connected to the roof side beam.

[0061] Referring to Figure 1 and Figure 2 , in some preferred embodiments, the structure of the rolling curtain folding frame 1 is specifically described:

[0062] The rolling curtain folding framework 1 includes a first rod 100 and two second rods 101 spaced along the length direction of the roof side beam; one end of each second rod 101 is a vehicle hinge part, and the other end is a rod end connection part; third rods 102 are hinged to the rod end connection parts of the two second rods 101;

[0063] The first rod 100, the second rods 101 and the third rods 102 are located in the same horizontal plane;

[0064] The first rod 100 is used to be arranged parallel to the roof side beam, and both ends of the first rod 100 are hinged to the ends of the two third rods 102 away from the second rods 101; the first rod 100 is a top support connection part.

[0065] Wherein, the flexible shielding curtain 2 is located on the top surface of the rolling curtain folding framework 1;

[0066] The telescopic top rod 3 is located below the horizontal plane where the rolling curtain folding framework 1 is located; one end of the telescopic top rod 3 connected to the first rod 100 is provided with a connection hinge shaft.

[0067] Wherein, a folding structure of the rolling curtain folding framework 1 is given to realize contraction and expansion. In addition, for further limitation of the connection positions of the telescopic top rod 3 with the roof side beam and the first rod 100 to facilitate more effective use of space, the following understandings should also be had:

[0068] Refer to Figure 2 the mark a in, the mark a is the midpoint of the first rod 100. It can be seen from Figure 2 that both ends of the telescopic top rod 3 are distributed on both sides of the mark a, so that a telescopic top rod 3 with a larger installation stroke can be installed in the same space.

[0069] Furthermore, the flexible shielding curtain 2 includes a waterproof cloth or a sunshade cloth; thus, it can shield rain while blocking the scorching sun. That is, with the popularization of new energy electric vehicles, the electric opening and closing door configuration is becoming more and more common. Along with this configuration, the use scenarios of intelligent car door rain curtains are more abundant. For example, the rain curtain does not require a rain sensor and can be associated with the electric vehicle door to move synchronously, playing the role of shielding rain and sun.

[0070] In some preferred embodiments, the telescopic top rod 3 includes an electric strut or a hydraulic strut.

[0071] The electric strut is driven by a built-in DC motor to drive a screw rod or a gear mechanism to convert rotational motion into linear telescopic motion. Its characteristics are precise control, which can be linked with the vehicle ECU electronic control unit to realize functions such as speed adjustment, anti-pinch, and memory of the telescopic length. It has low noise, and the motor runs with less noise. It has high reliability, no risk of hydraulic oil leakage, and a long service life.

[0072] The hydraulic strut is driven by a hydraulic pump to push the hydraulic oil pressure to drive the strut to extend and retract, and it can also achieve the function of extension and retraction. However, the change in the viscosity of the hydraulic oil in a low-temperature environment may affect the performance, there is a risk of leakage, and the maintenance cost is high. Therefore, the best implementation method is to select an electric strut.

[0073] Second, in order to enable the above-mentioned car door rain shield to be actually applied on a vehicle, a vehicle is also proposed, which includes:

[0074] A roof side beam, in the area corresponding to the car door, is provided with a recess or a groove to form a receiving space for accommodating the car door rain shield; the recess can be understood as having only a concave pit, but having a bottom wall for connecting and installing the rolling curtain folding frame 1 and the telescopic top rod 3; the groove has no bottom wall, so an installation sheet metal provided in the groove needs to be additionally provided to provide an installation position; the receiving space can refer to Figure 5 the marked A shown;

[0075] The controller 4 of the car door rain shield is the ECU of the vehicle; the controller 4 is also connected to a rain sensor 5.

[0076] When the above-mentioned car door rain shield is stored in the receiving space after use, there is a problem that dust and rainwater enter the receiving space. If it is not discharged in time, there will be a problem of rust. Therefore, a drain pipe can be provided inside and outside the receiving space; in addition, for a perfect hiding effect, a rubber cover plate for blocking the receiving space can be provided on the first rod 100.

[0077] In the receiving space, the flexible shielding curtain 2 is located on the top surface of the rolling curtain folding frame 1;

[0078] The telescopic top rod 3 is located below the horizontal plane where the rolling curtain folding frame 1 is located; one end of the telescopic top rod 3 connected to the first rod 100 is provided with a connecting hinge shaft; such a setting is that the flexible shielding curtain 2 can be used as a protective part to prevent rainwater from contacting the telescopic top rod 3 and reduce rust and rainwater erosion.

[0079] Third, the above-mentioned car door rain shield also needs to be equipped with a corresponding control method to achieve the function of opening on rainy days and not opening on non-rainy days.

[0080] Therefore, a control method for a car door rain shield of a vehicle is proposed, which includes the following steps:

[0081] Step 100, obtain rainfall information by using the rain sensor 5, and obtain car door status information by using the controller 4;

[0082] Step 200, based on the rainfall information and the car door status information, and combined with the controller 4, control the telescopic top rod 3 to extend or retract.

[0083] The above combines rainfall information and door state information to jointly control the opening of the door rain shield. When the door is closed, there is no need to manually close the rain shield anymore, and it can basically follow the opening and closing of the door when it rains.

[0084] In some preferred embodiments, the following detailed description is made for step 200;

[0085] The first control method:

[0086] Based on the rainfall information and the door state information, and in combination with the controller 4, control the extension or shortening of the telescopic top rod 3, which specifically includes the following steps:

[0087] When the rainfall information is less than the design threshold, control the telescopic top rod 3 to maintain the initial contracted state;

[0088] When the rainfall information is greater than or equal to the design threshold and the door state information is that the door opening angle is greater than or equal to the design threshold, control the telescopic top rod 3 to extend;

[0089] After the telescopic top rod 3 completes the extension and the door opening angle changes to less than the design threshold, control the telescopic top rod 3 to contract.

[0090] The above controls the extension or shortening of the telescopic top rod 3 by coordinating with the rainfall information at the door opening angle. In this method, only the switch of the telescopic top rod 3 needs to be controlled, and the current information and stroke information of the telescopic top rod 3 are not concerned. Moreover, this control method is limited to vehicles equipped with electrically opened doors and is difficult to apply to ordinary vehicles. Therefore, to expand the applicable range and also be applicable to ordinary vehicles and further achieve precise control, there is a second control method.

[0091] The second control method:

[0092] When the telescopic top rod 3 is an electric strut, the vehicle door rain shield control method further includes:

[0093] Use the controller 4 to obtain the current information of the electric strut, and replace the step of controlling the extension or shortening of the telescopic top rod 3 based on the rainfall information, the door state information, and in combination with the controller 4 with controlling the extension or shortening of the telescopic top rod 3 based on the rainfall information, the current information, and the door state information, and in combination with the controller 4.

[0094] Based on the rainfall information, the current information, and the door state information, and in combination with the controller 4, control the extension or shortening of the telescopic top rod 3, which specifically includes the following steps:

[0095] When the rainfall information is less than the design threshold, control the telescopic top rod 3 to maintain the initial contracted state;

[0096] When the rainfall information is greater than or equal to the design threshold and the door state information indicates that the door lock is open, control the telescopic push rod 3 to extend after a designed time from when the door lock is opened; the designed time ensures the opening angle of the door and provides space for the rain shield to unfold after opening.

[0097] When the telescopic push rod 3 has completed extension, the door state information indicates that the door lock is open, and the current value of the current information is greater than the target current, control the telescopic push rod 3 to retract.

[0098] The above uses the switch of the electric strut and the principle that the current will increase when the electric strut encounters a large resistance during its working process as the control signal for retraction; that is, when the door is about to close, the door squeezes the rolling curtain folding frame 1 and the telescopic push rod 3, the current on the electric strut will increase, and after the ECU receives the signal of increased current, it sends a retraction signal to the electric strut, thus realizing the opening of the door rain shield when it is raining and the door is open; when the door is closed, there is no need to manually close the rain shield, and it can basically move with the opening and closing of the door on rainy days.

[0099] In addition, an important point is that this set of control methods allows the door rain shield to be applied to vehicles with electric doors that do not have automatic door opening, and there is no need to be gear-connected to the door drive motor.

[0100] In the above two methods, the anti-pinch function cannot be realized. That is, when the door opening angle is greater than the design threshold but not fully unfolded, the unfolding of the door rain shield will interfere with the door. Therefore, the following settings are made for the second control method:

[0101] During the extension process of the telescopic push rod 3 after the designed time from when the door lock is opened, if the current value of the current information is greater than the target current, control the telescopic push rod 3 to stop extending. That is, when the rolling curtain reaches the maximum or encounters an obstacle during the opening process, the current on the electric strut will increase, and after the ECU receives the signal of increased current, it sends a stop command to the electric strut.

[0102] When the telescopic push rod 3 is a hydraulic strut, referring to the above method of the electric strut, replace the current value with the hydraulic pressure value, and the rest of the control methods are similar.

[0103] For this application, it should be understood that:

[0104] The material of the rolling curtain folding frame can be steel or a rigid material. The above designed time, design threshold, and target current need to be calibrated in practice. Since the sizes of the door rain shields corresponding to each vehicle are different and the required unfolding lengths are also different, specific numerical limits are not given.

[0105] The above vehicles include passenger cars, commercial vehicles, new energy vehicles, or traditional fuel vehicles, etc., and can be applied as long as there is a need for rain protection.

[0106] In a fourth aspect, an embodiment of the present application further provides a control device for a vehicle door rain shield, which includes:

[0107] A first module, which is used to obtain rainfall information by using a rainfall sensor 5 and obtain door state information by using a controller 4;

[0108] A second module, which is used to control the extension or shortening of a telescopic push rod 3 based on the rainfall information and the door state information and in combination with the controller 4.

[0109] Among them, the function implementation of each module in the above vehicle door rain shield control device corresponds to each step in the above vehicle door rain shield control method embodiment, and its function and implementation process will not be elaborated here one by one.

[0110] In a fifth aspect, an embodiment of the present application provides a control device for a vehicle door rain shield. The control device for a vehicle door rain shield can be a device with data processing functions such as a personal computer (PC), a notebook computer, a server, etc.
