[0033] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the specific technical solution of the present application will be further described in detail below in conjunction with the drawings in the embodiments of the present application. The following embodiments are used to illustrate the present application, but are not used to limit the scope of the present application.

[0034] In the embodiments of the present application, the terms "first" and "second" are used for descriptive purposes only and are not to be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features.

[0035] In addition, in the embodiments of the present application, directional terms such as "up", "down", "left" and "right" are defined relative to the orientation of the components in the drawings. It should be understood that these directional terms are relative concepts. They are used for relative description and clarification, and they may change accordingly according to the changes in the orientation of the components in the drawings.

[0036] In the embodiments of the present application, unless otherwise clearly specified and limited, the term "connection" should be understood in a broad sense. For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; it can be a direct connection or an indirect connection through an intermediate medium.

[0037] In the embodiments of the present application, the terms "include", "comprises" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also includes other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, an element defined by the sentence "comprises a ..." does not exclude the presence of other identical elements in the process, method, article or device including the element.

[0038] In the embodiments of the present application, words such as "exemplary" or "for example" are used to indicate examples, illustrations or descriptions. Any embodiment or design described as "exemplary" or "for example" in the embodiments of the present application should not be interpreted as being more preferred or more advantageous than other embodiments or designs. Specifically, the use of words such as "exemplary" or "for example" is intended to present related concepts in a specific way.

[0039] In order to solve the problem that there are a large number of control switches in existing vehicles, resulting in complicated in-vehicle layout and prolonged passenger learning period, the embodiments of the present application provide a vehicle door and window control device, a vehicle door and a vehicle.

[0040] Combine the following Figures 1 to 6 , the embodiments of the present application are described.

[0041] The embodiment of the present application provides a vehicle, including a vehicle body for carrying passengers. Specifically, in order not to affect passengers getting on and off the vehicle, not only are multiple door installation positions set on the periphery of the vehicle body, but also a vehicle door 11 is set on each vehicle door installation position. In this way, not only will it not affect passengers getting on and off the vehicle, but it can also allow the vehicle body to form a relatively closed space, that is, the vehicle body can form a complete protective structure. It is understandable that since the air circulation in the closed space is relatively poor, it will reduce the riding experience of passengers. Therefore, it is usually necessary to set an openable window on the vehicle door 11 so that fresh air can be added to the interior of the vehicle body in a timely manner to increase the air circulation inside and outside the vehicle.

[0042] It should be noted that the vehicle in this application may refer to a large car, a small car, a special-purpose car, etc. For example, according to the car model, the car in this application may be a sedan, an off-road vehicle, a multi-purpose vehicle (MPV) or other models. Generally, a vehicle is provided with wheels, a power source, and a transmission system arranged between the wheels and the power source. The transmission system can transmit the power provided by the power source to the wheels, so that the wheels rotate, thereby driving the vehicle to travel.

[0043] It should be noted that in the embodiments of the present application, the type of the power source of the vehicle is not limited. For example, for a fuel vehicle, the power source may refer to a fuel engine such as a gasoline engine or a diesel engine; for an electric vehicle, the power source may refer to an electric motor; for a hybrid vehicle, the power source may refer to an engine or an electric motor; for a vehicle powered by other means, the power source may refer to a device that generates power.

[0044] In some existing vehicles, two control switches are usually set in the vehicle body, one of which is used to open the door 11 inside the vehicle body so that passengers can get off the vehicle; the other control switch is used to control the rise and fall of the window inside the vehicle body so that passengers can control the air flow of external air into the vehicle body. However, setting multiple control switches in the vehicle body will not only prolong the learning time of passengers, but also increase the production and development costs of the vehicle.

[0045] In order to overcome the above problems, an embodiment of the present application provides a vehicle door, which includes a vehicle door and window control device. Specifically, Figure 1 As shown, the vehicle door and window control device includes: a parallel circuit 1, a selection switch 2 and a control unit 3.

[0046] Specifically, the parallel circuit 1 includes multiple parallel branches; the selection switch 2 is suitable for being electrically connected to one of the branches; the control unit 3 is electrically connected to the parallel circuit 1, and is suitable for obtaining the voltage across the branch electrically connected to the selection switch 2 to control the lifting of the window or the opening of the door 11.

[0047] The embodiment of the present application connects the selection switch 2 to one of the branches in the parallel circuit 1, so that passengers can realize independent control of the three actions of window raising, window lowering and door 11 opening through one switch, that is, the functions of two control switches are integrated into one switch at the same time. In this way, on the one hand, the number of control switches in the vehicle body can be reduced, the layout in the vehicle can be optimized, and the vehicle can meet the requirements of lightweight; on the other hand, the convenience of operation can be improved, the learning time of passengers can be shortened, and the passenger experience can be improved. In addition, the present application obtains the voltage information on the branch by using the control unit 3, and then controls the lifting of the window or the opening of the door 11 based on the voltage information obtained, thereby improving the automation degree and operation reliability of the vehicle door and window control device.

[0048] In addition, the control unit 3 in the embodiment of the present application can adopt the vehicle's own body domain controller. Since it not only has information collection function but also control function, it can reduce the structural complexity of the vehicle door and window control device and improve the reliability of the vehicle door and window control device.

[0049] In some embodiments of the present application, each branch is provided with a resistor 104 with different resistance values, and the control unit 3 is adapted to obtain the voltage drop across the resistor 104 on the corresponding branch. It can be understood that when the selection switch 2 is connected to one of the branches of the parallel circuit 1, it means that there will be a voltage drop across the resistor 104 on the branch, and then the control unit 3 controls the window or door 11 to complete the corresponding operation according to the obtained voltage drop information.

[0050] In order to avoid the door 11 and the window from interfering with each other during operation, Figure 2 As shown, in a specific embodiment, the vehicle door and window control device further includes a window driver 4 (e.g., a motor) and a door driver 5 (e.g., a motor), and the window driver 4 and the door driver 5 are electrically connected to the control unit 3. In this way, the control unit 3 can control the window and the door 11 respectively by using the window driver 4 and the door driver 5, so that the window and the door 11 can operate relatively independently, thereby improving the reliability of the vehicle door and window control device. Furthermore, by electrically connecting the window motor and the door 11 motor to the control unit 3, the automation level of the vehicle door and window control device can be improved, and the user experience can be improved.

[0051] In some embodiments of the present application, a contact 105 is provided at one end of each branch circuit, and the selection switch 2 is electrically connected to the contact 105 by pushing. By providing the contact 105, on the one hand, the connectivity between the selection switch 2 and the parallel circuit 1 can be improved, and on the other hand, the number of electrical components such as joints and connectors can be reduced, thereby reducing the failure rate of the circuit and the subsequent maintenance cost.

[0052] In some embodiments of the present application, the plurality of branches at least include a window raising circuit 101, a window lowering circuit 102, and a door opening circuit 103. Further, in order to enrich the control forms of the window movement, the window raising circuit 101 further includes a continuous raising circuit 1011 and a click raising circuit 1012 connected in parallel, and the window lowering circuit 102 further includes a continuous lowering circuit 1021 and a click lowering circuit 1022 connected in parallel.

[0053] It can be understood that when the selection switch 2 is connected to the continuous rising circuit 1011 and forms a loop, the selection switch 2 is released and disconnected from the continuous rising circuit 1011, and the control unit 3 will control the window drive 4 to drive the window to continue to rise until the window is completely closed; when the selection switch 2 is connected to the click-to-rise circuit 1012 and forms a loop, the time when the control unit 3 controls the window drive 4 to work will be consistent with the connection time between the selection switch 2 and the click-to-rise circuit 1012, that is, when the selection switch 2 and the click-to-rise circuit 1012 are in a connected state, the window will continue to rise under the drive of the window drive 4, and if the selection switch 2 is disconnected from the click-to-rise circuit 1012, the window drive 4 and the window will stop moving.

[0054] When the selection switch 2 is connected to the continuous descending circuit 1021 and forms a loop, the selection switch 2 is released and disconnected from the continuous descending circuit 1021, and the control unit 3 controls the window driver 4 to drive the window to continue to descend until the window is fully opened; when the selection switch 2 is connected to the click-down circuit 1022 and forms a loop, the time when the control unit 3 controls the window driver 4 to work will be consistent with the connection time between the selection switch 2 and the click-down circuit 1022, that is, when the selection switch 2 and the click-down circuit 1022 are in a connected state, the window will continue to descend under the drive of the window driver 4, and if the selection switch 2 is disconnected from the click-down circuit 1022, the window driver 4 and the window will stop moving. Similarly, when the selection switch 2 is connected to the door opening circuit 103, the control unit 3 controls the door driver 5 to open the door.

[0055] It should be noted that if the window is continuously rising and the passenger performs other window operations or triggers the window's anti-pinch function, the window will stop rising. Similarly, if the window is continuously falling and the passenger performs other window operations, the window will stop falling.

[0056] It can be understood that resistors 104 with different resistance values ​​are provided on the continuous rising circuit 1011, the click rising circuit 1012, the continuous falling circuit 1021, the click falling circuit 1022 and the door opening circuit 103 in the embodiment of the present application, so that the control unit 3 can accurately determine the connection between the selection switch 2 and a branch in the parallel circuit 1, and then control the window driver 4 or the door driver 5 to complete the corresponding operation. For example, the resistance value of the resistor on the continuous rising circuit 1011 is 10 ohms; the resistance value of the resistor on the click rising circuit 1012 is 8 ohms; the resistance value of the resistor on the continuous falling circuit 1021 is 6 ohms; the resistance value of the resistor on the click falling circuit 1022 is 4 ohms; and the resistance value of the resistor on the door opening circuit 103 is 2 ohms. In order to reduce the manufacturing cost of the vehicle door and window control device, the resistance value of the resistor 104 on one of the continuous rising circuit 1011, the click rising circuit 1012, the continuous falling circuit 1021, the click falling circuit 1022 and the door opening circuit 103 can be set to 0 ohms, that is, the resistor 104 is not set on this branch.

[0057] In order to adapt the working logic of the selector switch 2 to the first use reaction of the passenger, Figure 1 As shown, for example, the contact 105 of the continuous rising circuit 1011, the contact 105 of the click rising circuit 1012, the contact 105 of the door opening circuit 103, the contact 105 of the click falling circuit 1022, and the contact 105 of the continuous falling circuit 1021 can be arranged in sequence from top to bottom. It can be understood that when the passenger pushes the selection switch 2 upward, the selection switch 2 will be connected to the contact 105 of the continuous rising circuit 1011 to form a loop, and the control unit 3 will control the window drive 4 to drive the window to continue to rise until the window is completely closed; when the passenger pushes the selection switch 2 upward slightly, the selection switch 2 will be connected to the contact 105 of the click rising circuit 1012 to form a loop, and the control unit 3 will control the window drive 4 to drive the window to rise; when the passenger pushes the selection switch 2 toward the outside of the vehicle body, the selection switch 2 will be connected to the contact 105 of the door opening circuit 1012 to form a loop, and the control unit 3 will control the window drive 4 to drive the window to rise; 3 is connected to the contact 105 of the click-down circuit 1022 to form a loop, and the control unit 3 controls the door driver 5 to unlock the door 11; when the passenger pushes the selection switch 2 downward lightly, the selection switch 2 is connected to the contact 105 of the click-down circuit 1022 to form a loop, and the control unit 3 controls the window driver 4 to drive the window down; when the passenger pushes the selection switch 2 downward forcefully, the selection switch 2 is connected to the contact 105 of the continuous descent circuit 1021 to form a loop, and the control unit 3 controls the window driver 4 to drive the window to continue to descend until the window is fully opened. In this way, not only are the two functions of window lifting and door 11 opening integrated into one switch, but the user's learning cost is also reduced, and the difficulty of getting started is reduced.

[0058] It should be noted that, in the embodiment of the present application, the arrangement direction of the contact 105 of the continuous rising circuit 1011, the contact 105 of the click rising circuit 1012, the contact 105 of the door opening circuit 103, the contact 105 of the click falling circuit 1022 and the contact 105 of the continuous falling circuit 1021 is consistent with the height direction of the vehicle ( Figure 1 In addition, in order to improve the safety of the selection switch 2 during use, the end of the selection switch 2 away from the parallel circuit 1 can be connected to the ground terminal.

[0059] In some embodiments of the present application, the selection switch 2 is arranged on the inner side of the vehicle door 11, which is basically the same as the setting position of the control switch in the existing vehicle, so that the passengers can find the position of the switch easily; in addition, in the present embodiment, the selection switch 2 has a reset function, so that the selection switch 2 can have two states, namely, disconnected and working, which is conducive to connecting the selection switch 2 with different branches in the parallel circuit 1.

[0060] Furthermore, in order to ensure that the selection switch 2 can be flexibly and stably switched between the disconnected state and the working state, an elastic member may be provided around the selection switch 2. Figures 3 to 5 As shown, the vehicle door and window control device also includes a switch seat 6, which is fixedly connected to the vehicle door 11, and the selection switch 2 is arranged opposite to the switch seat 6. A first elastic member 7 is arranged between the selection switch 2 and the switch seat 6, and second elastic members 8 are respectively arranged on opposite sides of the selection switch 2. The expansion and contraction directions of the first elastic member 7 and the second elastic member 8 are arranged vertically; the selection switch 2 is suitable for entering the disconnected state through the elastic reset of the first elastic member 7 or the second elastic member 8. By arranging the first elastic member 7 and the second elastic member 8, the selection switch 2 can have an automatic reset function, that is, when the passenger releases the selection switch 2, the selection switch 2 will return to the initial position, and the selection switch 2 will switch from the working state to the disconnected state. In this way, the reliability and safety of the selection switch 2 are improved.

[0061] It should be noted that the shape of the selection switch 2 in the embodiment of the present application can be a strip, a circle or an ellipse, and the present application does not make any specific limitation on this. In addition, the first elastic member 7 and the second elastic member 8 can be but are not limited to elastic members such as springs, rubber gaskets and metal gaskets.

[0062] In a specific embodiment, the length direction of the selection switch 2 is consistent with the length direction of the vehicle and is arranged on the inner side of the vehicle door 11, the first elastic member 7 is arranged along the thickness direction of the vehicle door 11, and the second elastic member 8 is arranged along the height direction of the vehicle door 11; when the first elastic member 7 is in a compressed state, the control unit 3 controls the vehicle door 11 to open; when the second elastic member 8 located above is in a compressed state, the control unit 3 controls the vehicle window to rise; when the second elastic member 8 located below is in a compressed state, the control unit 3 controls the vehicle window to fall. Such a setting can make the operation logic of the selection switch 2 compatible with the first use reaction of the passenger, that is, when the passenger pushes the selection switch 2 to move upward, the selection switch 2 will be connected to the vehicle window rising circuit 101; when the passenger pushes the selection switch 2 to move downward, the selection switch 2 will be connected to the vehicle window falling circuit 102; when the passenger pushes the selection switch 2 to move outward (moving in the direction away from the vehicle body), the selection switch 2 will be connected to the vehicle door opening circuit 103; thereby greatly improving the adaptation speed of the passenger, reducing the difficulty of the passenger to get started and the probability of misoperation. It should be noted that, in the embodiment of the present application, the thickness direction of the door 11 is equal to the width direction of the vehicle ( Figure 1 In the embodiment of the present application, the height direction of the door 11 is consistent with the height direction of the vehicle ( Figure 1 The direction shown in A is consistent with that in FIG.

[0063] In another embodiment, the length direction of the switch 2 and the height direction of the vehicle ( Figure 1 The first elastic member 7 is arranged along the height direction of the vehicle, and the second elastic member 8 is arranged along the length direction of the vehicle. When the first elastic member 7 is in a compressed state, the control unit 3 controls the vehicle door 11 to open; when the second elastic member 8 located in front of the vehicle body is in a compressed state, the control unit 3 controls the vehicle window to rise; when the second elastic member 8 located behind the vehicle body is in a compressed state, the control unit 3 controls the vehicle window to fall.

[0064] It can be understood that the arrangement directions of the first elastic member 7 and the second elastic member 8 in the embodiment of the present application can be adjusted accordingly according to design requirements, and the present application does not make any specific limitation on this.

[0065] In some embodiments of the present application, a pull-up power supply 9 and a pull-up resistor 10 are further included. The pull-up power supply 9 is connected in series with the parallel circuit 1, and the pull-up resistor 10 is arranged on the circuit between the pull-up power supply 9 and the parallel circuit 1. By setting the pull-up power supply 9, the parallel circuit 1, the control unit 3 and other structures can be provided with the electric energy required for their normal operation. Furthermore, by setting the pull-up resistor 10 on the circuit between the pull-up power supply 9 and the parallel circuit 1, the parallel circuit 1 can be kept at a high level even when it is disconnected, thereby improving the reliability of the circuit.

[0066] The following describes the working process of the vehicle door and window control device in the embodiment of the present application with reference to a specific example. Figure 1 and Figure 6 As shown, the resistance of the resistor 104 on the door opening circuit 103 is set to zero, and R1, R2, R4, and R5 are used to represent the resistor 104 located on the continuous rising circuit 1011, the click rising circuit 1012, the continuous falling circuit 1021, and the click falling circuit 1022 respectively.

[0067] When the passenger pushes the selection switch 2, the control unit 3 starts to obtain the voltage information on the parallel circuit 1;

[0068] If the control unit 3 detects the voltage drop of R1, it will control the window drive 4 to drive the window to continue to rise until the window is completely closed. During this process, if there are other window operations or the window anti-pinch function is triggered, the window will stop rising;

[0069] If the control unit 3 detects the voltage drop of R2, it will control the window driver 4 to drive the window up until the selection switch 2 is disconnected from the click-up circuit 1012, that is, the control unit 3 cannot detect the voltage drop of R2;

[0070] If the control unit 3 detects the voltage drop of R4, it will control the window drive 4 to drive the window down until the selection switch 2 is disconnected from the click-down circuit 1022, that is, the control unit 3 cannot detect the voltage drop of R4;

[0071] If the control unit 3 detects the voltage drop of R5, it will control the window drive 4 to drive the window to continue to drop until the window is fully opened. If there are other window operations during this process, the window will stop dropping;

[0072] If the pressure drop value collected by the control unit 3 is 0, the control unit 3 will consider that the passenger has a door opening requirement, and then control the door drive 5 to drive the door 11 to open;

[0073] If the control unit 3 cannot detect the voltage drop, it means that the selection switch 2 is disconnected from the parallel circuit 1 under the elastic reset action of the first elastic member 7 and the second elastic member 8, and it is assumed that the passenger has no need to open the door 11 or raise or lower the window. In addition, when the control unit 3 cannot detect the voltage drop, the control unit 3 will also determine whether the door 11 or the window has an unfinished action. For example, when it is found that the window is not completely closed, the control unit 3 will control the window driver 4 to work again until the window is completely closed; if it is found that the action of the door 11 or the window has been completed, the control unit 3 will not control the door driver 5 or the window driver 4 to work; if during this process, the voltage drop of the resistor 104 in the circuit is abnormal, the information that the vehicle door and window control device has a fault will be immediately reported to the passenger.

[0074] The serial numbers of the embodiments of the present application are only for description and do not represent the advantages and disadvantages of the embodiments. The above are only preferred embodiments of the present application, and do not limit the patent scope of the present application.
