[0061] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0062] It should be noted that when a component is referred to as being "fixed to" another component, it may be directly on the other component or there may be an intermediate component. When a component is referred to as being "connected to" another component, it may be directly connected to the other component or there may be an intermediate component.

[0063] Unless otherwise defined, all technical and scientific terms used in this application have the same meanings as those commonly understood by those skilled in the art to which this application belongs. The terms used in this specification are for the purpose of describing specific embodiments only and are not intended to limit this application. The term "and / or" as used in this application includes any and all combinations of one or more of the relevant listed items.

[0064] The following describes some embodiments of the present application in detail with reference to the accompanying drawings. In the absence of conflict, the following embodiments and features therein may be combined with each other.

[0065] The present application proposes a vehicle, which can be an electric car, a fuel car, or a hybrid car. The vehicle can be a car, an off-road vehicle, a truck, or a forklift, and the present application does not impose any restrictions on this. The vehicle includes a body, doors, window glass, a window lifting mechanism, and a door water cut. The body serves as the supporting skeleton of the vehicle and is used to support and connect the various assemblies of the vehicle. The body is provided with a door opening for people to enter and exit. The door is connected to the body and covers the door opening. The door has an installation cavity. The window lifting mechanism is provided in the installation cavity. The window lifting mechanism is connected to the window glass. The window lifting mechanism is used to lift the window glass to cover the window of the door, or to lower the window to accommodate it in the installation cavity of the door.

[0066] Door seals are installed between the door panel and the window glass to prevent dust and debris from entering the door's mounting cavity. To ensure a proper seal, a certain amount of interference is typically maintained between the seal and the window glass. If this interference is set too high, it can cause severe friction between the window glass and the seal when the window is raised or lowered, leading to unusual window noise and impacting the vehicle's NVH performance. If the interference is set too low, the seal of the vehicle's doors and windows can be compromised.

[0067] To ensure the sealing of the window glass and improve the quietness of the window glass lifting and lowering, please refer to Figure 1 and Figure 2 In this application, a vehicle door seal 100 includes a body 1 and a sealing lip 2. The body 1 serves as the main structure of the vehicle door seal 100 and is used to connect to the vehicle door. The sealing lip 2 has a first end 21 and a second end 22 that are oppositely disposed. The first end 21 is connected to the body 1, and the second end 22 can move toward or away from the body 1. When the second end 22 is away from the body 1, the second end 22 is used to contact the vehicle window glass 200 to seal the vehicle window glass 200. When the second end 22 is close to the body 1, the second end 22 is used to separate from the vehicle window glass 200.

[0068] The technical solution of this application makes the second end 22 of the sealing lip 2 movable. When the vehicle controller receives a signal to raise or lower the window glass 200, the vehicle controller controls the second end 22 of the sealing lip 2 to move closer to the body 1, thereby separating the sealing lip 2 from the window glass 200. This reduces friction between the sealing lip 2 and the window glass 200, thereby avoiding or alleviating the abnormal noise caused by the raising and lowering of the window glass 200 and improving the quietness of the raising and lowering of the window glass 200. When the vehicle controller receives a signal to stop the vehicle, the vehicle controller controls the second end 22 of the sealing lip 2 to move away from the body 1, causing the sealing lip 2 to contact the window glass 200, thereby forming a seal between the vehicle door and the window glass 200, improving the vehicle's waterproof and dustproof performance.

[0069] The sealing lip 2 defines a drive cavity 23. The door hydraulic system 100 also includes a deformable member 3, one end of which extends into the drive cavity 23. The deformable member 3 can deform to control the movement of the second end of the sealing lip. The deformable member 3 can deform in a variety of ways. In one embodiment of the present application, the deformable member 3 is an elastic member, which can be made of elastic metal or elastic rubber. The door hydraulic system includes a cylinder, the cylinder base of which is fixed to the vehicle body, and the cylinder piston rod is positioned corresponding to the deformable lip. When the window glass 200 stops rising or falling, the cylinder piston rod extends toward the sealing lip, pushing the second end of the sealing lip toward the window glass 200, thereby sealing the window glass 200. When the window glass 200 begins to rise or fall, the cylinder piston rod withdraws from the sealing lip. Without the external force, the deformable member 3 returns to its original shape under the action of the elastic force, thereby driving the second end of the sealing lip away from the window glass 200.

[0070] In other possible embodiments of the present application, the deformable member 3 may also be made of a nickel-titanium alloy, which has the property of deforming upon heating and returning to its original shape upon cooling. In this embodiment, the door hydraulic system further includes a heating device 4 connected to the end of the deformable member 3 distal from the drive cavity 23. The deformable member 3 is initially configured as a long strip and is then configured into a curled shape after heating. When the window glass 200 begins to rise or fall, the heating device 4 heats the deformable member 3, causing it to curl, thereby driving the second end 22 away from the window glass 200. When the window glass 200 stops rising or falling, the heating device 4 ceases heating, causing the deformable member 3 to cool and return to its original shape, thereby driving the second end 22 toward the window glass 200. Compared to other drive methods, the heating device 4 and deformable member 3 provided in this embodiment occupy less space in the mounting cavity and have lower installation costs. This effectively optimizes the layout of the door mounting cavity and improves the space utilization of the deformable member 3 within the door mounting cavity.

[0071] The vehicle door watertightening device 100 further includes a piping structure 5, which is disposed within the mounting cavity of the vehicle door and connected to the main body 1. The piping structure 5 and the main body 1 may be integrally formed or separately formed and then connected via heat pressing, bonding, or other methods, without limitation in this application. The piping structure 5 is provided with an air hole 52 for blowing air toward the vehicle window glass 200, thereby quickly removing water stains and dirt from the vehicle window glass 200 and improving driving safety.

[0072] Specifically, the pipe structure 5 is formed with an air cavity 51, and air flows through the air cavity 51. The pipe structure 5 is also provided with an air blowing hole 52 connected to the air cavity 51. When the controller of the car door water cut 100 detects the presence of water droplets on the car window glass 200, air flow will be passed into the air cavity 51. Under the action of air pressure, the air flow can be blown toward the car window glass 200 through the air blowing hole 52 connected to the air cavity 51, and then the water droplets on the car window glass 200 are blown into the installation cavity. A drainage hole will be provided at the bottom of the installation cavity, and the water droplets entering the installation cavity will be discharged out of the car door through the drainage hole. In this way, the water droplets and dirt remaining on the car window glass 200 can be quickly removed on rainy days or after washing the car, thereby ensuring that the driver can clearly see the road conditions and improving driving safety.

[0073] There are many ways to form the air cavity 51. In one embodiment of the present application, the piping structure 5 is configured as a circular tube, and the air cavity 51 is formed within the lumen of the circular tube. In other embodiments of the present application, the piping structure 5 can also be configured as a semicircular tube, with the lumen of the semicircular tube facing the body 1, and the semicircular tube and the body 1 jointly enclose the air cavity 51.

[0074] The door water jetting device 100 further includes an air source device 6 , which can be an axial flow air pump, a centrifugal air pump, or a screw air pump, without limitation in this application. The air source device 6 is in communication with the air cavity 51 and can provide airflow to the air cavity 51 when needed, thereby cooperating with the pipeline structure 5 to remove water droplets from the window glass 200 and protect the driver's driving safety.

[0075] Please refer to Figure 3 The vehicle also includes a controller for door water cutting, and the controller for door water cutting includes a receiving module and a driving module, and the receiving module is used to receive signals from the window glass. The driving module is used to drive the second end to move towards the direction close to the body when a rising signal or a falling signal of the window glass is obtained. The technical solution of the present application is to set the second end of the sealing lip to be movable. When the vehicle controller receives a rising or falling signal of the window glass, the vehicle control system controls the second end of the sealing lip to move away from the window glass, so as to reduce the friction between the sealing lip and the window glass, thereby avoiding or alleviating the abnormal noise of the window glass rising and falling, and improving the quietness of the window glass rising and falling. When the vehicle controller receives a vehicle stop signal, the vehicle controller controls the second end of the sealing lip to move towards the window glass, thereby forming a seal between the door and the window glass, and improving the waterproof and dustproof performance of the vehicle.

[0076] Please refer to Figure 4The vehicle provided in this application also includes a controller 1001, a communication bus 1002, a user interface 1003, a network interface 1004 and a memory 1005. The communication bus 1002 is used to realize the connection and communication between these components. The user interface 1003 is mainly used for users to interact with data. The user interface 1003 may include a display screen (Display), an input unit such as a keyboard (Keyboard), and the optional user interface 1003 may also include a standard wired interface and a wireless interface. The network interface 1004 is mainly used for data communication with a network server. The network interface 1004 may optionally include a standard wired interface and a wireless interface (such as a wireless fidelity (Wi reless-Fidelity, Wi-Fi) interface).

[0077] The controller 1001 is used to call computer instructions to execute the seat belt control method. The controller 1001 can be a central processing unit (CPU). The controller 1001 can also be other general controllers, digital signal controllers (DSP), application-specific integrated circuits (ASIC), field-programmable gate arrays (FPGA), or other programmable logic devices, discrete gate or transistor logic devices, discrete hardware components, etc.

[0078] Memory 1005 is used to store computer instructions. Memory 1005 is used to store an operating system, a network communication module, a user interface module, and a door water-cut control program. Memory 1005 can be volatile memory or non-volatile memory, or can include both volatile and non-volatile memory. Non-volatile memory can be read-only memory (ROM), programmable read-only memory (PROM), erasable programmable read-only memory (EPROM), electrically erasable programmable read-only memory (EEPROM), or flash memory. Volatile memory can be random access memory (RAM), which is used as an external cache. By way of example and not limitation, many forms of RAM are available, such as static random access memory (SRAM), dynamic random access memory (DRAM), synchronous dynamic random access memory (SDRAM), double data rate synchronous dynamic random access memory (DDR SDRAM), enhanced synchronous dynamic random access memory (ESDRAM), synchronous link dynamic random access memory (SLDRAM), and direct RAMbus RAM (DR RAM).

[0079] It should be noted that when the controller 1001 is a general controller, DSP, ASIC, FPGA or other programmable logic device, discrete gate or transistor logic device, discrete hardware component, the memory (storage module) is integrated into the controller.

[0080] It should be noted that the memory described herein is intended to include, but not be limited to, these and any other suitable types of memory.

[0081] In addition to the data bus, the bus may also include a power bus, a control bus, a status signal bus, etc. However, for the sake of clarity, various buses are labeled as buses in the figure.

[0082] The present application also proposes a storage medium on which a control program for door water cutting is stored. The control program for door water cutting is executed by a controller to implement a seat belt control method to solve the problem that passengers need to turn sideways to fasten their seat belts, improve the convenience of passengers in grabbing and installing the belts, and improve the passengers' riding experience.

[0083] Hereinafter, the control method of the vehicle door water shear provided by the present application will be described in detail.

[0084] Please refer to Figure 5 , Figure 5 This is a flow chart of the first embodiment of the method for controlling the vehicle door water cut provided in this application. In this embodiment, the vehicle door water cut includes a main body and a sealing lip, the sealing lip having a first end and a second end relatively arranged, the first end being connected to the main body, and the second end being able to move closer to or away from the main body.

[0085] The control methods for door water shear include:

[0086] S101 : When a movement signal of a vehicle window glass is received, control the second end to move toward the main body.

[0087] The motion signal can be a signal indicating the window glass is rising or falling. There are various ways for the controller to obtain the window glass motion signal. In one embodiment of the present application, the window lift mechanism includes a window motor, a screw, and a slider. The window motor serves as the power source for the window lift mechanism, providing power for the movement of the window glass. The window motor has a drive unit, to which the screw is connected. The slider is screwed onto the screw and is connected to the window glass. When the window motor's drive unit rotates clockwise, the screw rotates clockwise and drives the slider upward. The upward movement of the slider drives the window glass upward, raising the window glass. When the window motor's drive unit rotates counterclockwise, the screw rotates counterclockwise, driving the slider downward. The downward movement of the slider drives the window glass downward, lowering it into the mounting cavity.

[0088] In this embodiment, the door water cut includes an information collector, which is connected to the window motor, and the information collector is used to collect the rotation information of the window motor drive unit. When the window motor drive unit rotates clockwise, the information collector sends a window up signal to the controller. When the window motor drive unit rotates counterclockwise, the information collector sends a window down signal to the controller. It can be understood that in other possible implementations of the present application, the drive unit may rotate counterclockwise, driving the slider to move upward, thereby raising the window glass, and the drive unit may rotate clockwise, driving the slider to move downward, thereby lowering the window glass. At this time, when the information collector detects that the drive unit is rotating counterclockwise, it sends a window down signal to the controller, and when the information collector detects that the drive unit is rotating clockwise, it sends a window up signal to the controller.

[0089] It is understood that in other possible embodiments of the present application, a position sensor may be installed on the vehicle body to sense the position of the window relative to the vehicle body. When the window glass moves upward, the position sensor sends an up signal to the controller. When the window glass moves downward, the position sensor sends a down signal to the controller, thereby obtaining the window glass movement signal.

[0090] There are various ways to control the second end of the sealing lip to move toward the body. In one embodiment of the present application, the door watertight part further includes a heating device and a deformable member, one end of the deformable member contacts the heating device, and the other end extends into the sealing lip. Controlling the second end to move toward away from the body includes the following steps:

[0091] The heating device is controlled to heat so that the deformable member is heated and curled.

[0092] In this embodiment, the second end of the sealing lip is driven by a deformable member. The deformable member is a nickel-titanium alloy. When this alloy is heated to a certain temperature, its crystal structure changes, causing its shape to change. When it is cooled, its crystal structure returns to its original state, causing its shape to also return to its original state. In this embodiment, by setting the original state of the deformable member to a long strip and the heated state to a curled shape, when the car door water cut needs to drive the second end to move toward the main body, it is only necessary to heat the deformable member through the heating device and curl the deformable member, so that the second end can be driven to move through the deformable member. Compared with other driving methods, the heating device and deformable member provided in this embodiment occupy a small space in the installation cavity and have a low layout cost. They can effectively optimize the layout of the door installation cavity and improve the space utilization rate of the deformable member for the door installation cavity.

[0093] It is understood that in other embodiments of the present application, a motor may be used to drive the second end of the sealing lip toward the body. Specifically, the door watertight mechanism includes a motor and a drive bar, one end of the drive bar connected to the motor and the other end connected to the sealing lip. The motor rotates, driving the drive bar to rotate, thereby driving the sealing lip toward the body.

[0094] S102: When a stop signal from the vehicle window glass is received, the second end is controlled to move away from the main body.

[0095] When the window glass rises or descends to its limit, or when it hovers at the window of the vehicle body, the device for acquiring window glass movement information sends a stop signal to the controller. Upon receiving the stop signal, the controller drives the second end to move away from the main body, thereby sealing the window. There are various ways to acquire the stop signal for the window glass. Similar to acquiring the movement signal of the window glass, in one embodiment of the present application, the door watertight system includes an information collector connected to the window motor for collecting rotation information of the window motor's drive unit. When the window motor's drive unit stops rotating, and the stopped rotation continues for a preset time, the information collector sends a stop signal to the controller. In other embodiments of the present application, the movement of the window glass can also be acquired using a position sensor. When the window glass remains at a certain position on the vehicle body for a preset time, the position sensor determines that the window glass has stopped rising and lowering, and then sends a stop signal to the controller. It should be noted that the preset time can be set according to the response speed required for the car door water cut. The preset time can be set to 1S or 2S, and this application does not impose any restrictions on this.

[0096] There are many ways to control the second end of the sealing lip to move away from the body. In one embodiment of the present application, controlling the second end to move toward the body includes the following steps:

[0097] The heating device is controlled to stop heating so that the deformed part returns to its original shape.

[0098] In this embodiment, the second end of the sealing lip is driven by a deformable element. This deformable element is a nickel-titanium alloy. When heated to a certain temperature, its crystal structure changes, resulting in a change in shape. When cooled, its crystal structure returns to its original state, causing its shape to also return to its original state. In this embodiment, the deformable element is configured as a long strip in its original state and a curled shape after heating. When the door needs to be hydraulically driven to move the second end away from the main body, simply turning off the heating device allows the deformable element to return to its original shape, thereby driving the second end away from the main body.

[0099] It is understood that similar to driving the second end toward the body, in other embodiments of the present application, a motor can also be used to drive the second end of the sealing lip toward the body. Specifically, the door watertight mechanism includes a motor and a drive bar, one end of which is connected to the motor and the other end to the sealing lip. The motor rotates, driving the drive bar to rotate, thereby driving the sealing lip away from the body.

[0100] This embodiment makes the second end of the sealing lip movable. When the vehicle controller receives a signal to raise or lower the window glass, it controls the second end of the sealing lip to move away from the window glass. This reduces friction between the sealing lip and the window glass, thereby preventing or mitigating unusual window raising and lowering noises and improving the quietness of the window glass. When the vehicle controller receives a signal to stop the vehicle, it controls the second end of the sealing lip to move toward the window glass, forming a seal between the door and window glass, improving the vehicle's waterproof and dustproof properties.

[0101] Please refer to Figure 6 , Figure 6 This is a flow chart of the second embodiment of the control method for vehicle door water cutting provided in the present application. In this embodiment, the vehicle door water cutting also includes a pipeline structure and an air source device. The pipeline structure and the main body are arranged to form an air cavity. The pipeline structure is provided with a blowing hole connected to the air cavity, and the air source device is connected to the air cavity.

[0102] The method for controlling door water shear comprises the following steps:

[0103] S201. When a window glass lowering signal is received, the flow rate of water droplets on the window glass is obtained.

[0104] There are many ways to obtain the flow rate of water flow. In one embodiment of the present application, a sensor is provided on the vehicle window glass. The sensor can be an infrared sensor, a microwave radar sensor, or a conductivity sensor. When an infrared sensor is used to obtain the flow rate of water droplets on the vehicle window glass by water cutting the vehicle door, the infrared sensor can measure the amount of rain on the glass by detecting the transmission or reflection of infrared rays. When a microwave radar sensor is used to obtain the flow rate of water droplets on the vehicle door glass, the microwave radar sensor can detect the amount of rain by the reflection and echo signals of the microwave radar. When a conductivity sensor is used to obtain the flow rate of water droplets on the vehicle window glass, the conductivity sensor can detect the amount of rain by measuring the change in conductivity on the glass. In other possible embodiments of the present application, an optical picture of water droplets on the vehicle window glass can be taken by a visual camera, and the amount of rain can be detected by monitoring the change in the optical image on the glass through machine vision.

[0105] S202: When the flow rate of the water flow on the vehicle window glass is greater than a preset threshold, control the air source device to pass air into the air cavity.

[0106] The preset threshold can be customized based on user needs. Generally, when the preset threshold is set to zero, the air supply device will activate and remove water from the window glass when water droplets are present. This ensures immediate removal of water from the window glass, improving driving safety. The preset threshold can also be set to a higher value, activating the air supply device and removing water from the window glass only when a large number of water droplets are present, thereby reducing vehicle energy consumption.

[0107] In this embodiment, an air source device is linked to the lowering of the vehicle window. When the controller detects the lowering of the vehicle window and the presence of water droplets on the window, it activates the air source device to direct air into the air cavity. Under the influence of air pressure, the airflow is blown toward the vehicle window glass through an air hole connected to the air cavity. The coordinated flow of air and the lowering movement of the vehicle window glass blows the water droplets on the vehicle window glass into the mounting cavity of the vehicle door and out of the vehicle body through a drainage hole at the bottom of the mounting cavity. This allows for the rapid removal of residual water droplets and dirt on the vehicle window glass during rainy days or after washing the vehicle, ensuring a clear view of the road for the driver and improving driving safety.
