[0043] In order to enable technicians in the technical field to which the present application belongs to understand the present application more clearly, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application, wherein similar or identical reference numerals may be used to designate the same or similar parts in different figures. The use of similar or identical reference numerals in different figures does not mean that all figures including similar or identical reference numerals constitute a single or the same embodiment. The drawings illustrate the various embodiments discussed in the present application in a general manner by way of example and not by way of limitation. Obviously, the described embodiments are only some of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in the field without making creative work are within the scope of protection of the present application.

[0044] In addition, the present application may repeat reference numbers and / or reference letters in different examples, and such repetition is for the purpose of simplicity and clarity, and does not in itself indicate the relationship between the various embodiments and / or settings discussed. In addition, the present application provides various specific examples of processes and materials, but those of ordinary skill in the art may recognize the application of other processes and / or the use of other materials.

[0045] In the related technology, the lifting of the rear door glass of some vehicles is often affected by the relative position of the rear wheels and the rear door, resulting in the door glass being unable to be lowered to the bottom (below the window sill line). Fig.11 , shows the relative position of the rear door glass 10 and the door 20 when the rear door glass 10 drops to the lowest point, from Fig.11 It can be seen that the rear wheel shape occupies the space where the rear door glass 10 is raised and lowered to the bottom. When the rear door glass 10 is lowered to the lowest point, its bottom has basically contacted the edge of the door, but the top is still higher than the window sill line 21.

[0046] To this end, the present application provides a door glass lifting system, method and vehicle, wherein the door glass adopts a mother-and-child glass structure, and the door glass can also be lowered to the bottom under the condition of shape restrictions. The specific technical solution of the present application will be described in detail below with reference to the accompanying drawings which are not necessarily drawn to scale.

[0047] The first embodiment of the present application provides a vehicle door glass lifting system, which is installed in the door body of the vehicle door assembly. It is understandable that the vehicle door glass lifting system of the present application can be installed in the front door assembly of the vehicle, or in the rear door assembly of the vehicle, or in the sunroof of the vehicle.

[0048] See also Figure 1The vehicle door glass lifting system 100 includes a glass assembly 110, a first lifting driving member 120 and a second lifting driving member 130. Figure 2 and Figure 3 The glass assembly 110 adopts a mother-and-child glass structure, including a first glass 111 and a second glass 112 that can move relatively. The first lifting drive 120 is used to drive the first glass 111 to rise and fall, and the second lifting drive 130 is used to drive the second glass 112 to rise and fall. The first lifting drive 120 and the second lifting drive 130 are both installed in the door body 200.

[0049] Since the second glass 112 can be retracted into the cavity 111a of the first glass 111, that is, the first glass 111 and the second glass 112 are arranged in sequence along the height direction of the vehicle, and the first glass 111 and the second glass 112 have an overlapping portion in the height direction of the vehicle, the first glass 111 and the second glass 112 together form a door glass along the height direction of the vehicle. Therefore, the volume of the glass assembly 110 is smaller than that of the integral glass in the prior art, and can be installed in a vehicle where the wheel shape occupies the space for the door glass to be raised to the bottom, and the door glass can be lowered to the bottom, such as Fig.10 shown.

[0050] Please combine Figure 4 , Figure 5 and Figure 6 The first glass 111 is provided with a cavity 111a with an open top, and the second glass 112 is movably arranged in the cavity 111a. That is, the first glass 111 is a mother glass, and the second glass 112 is a mother glass. Fig. 7A and Figure 7B When the second glass 112 moves outward relative to the first glass 111 (i.e., the second glass 112 rises), a portion of the second glass 112 is always embedded in the first glass 111, and this portion of the second glass 112 serves as a guide structure for the second glass 112, while preventing the first glass 111 from being separated from the second glass 112. When the second glass 112 moves inward relative to the first glass 111 (i.e., the second glass 112 falls), the second glass 112 may be partially embedded in the first glass 111 or completely retracted into the first glass 111. The retraction of the second glass 112 relative to the first glass 111 may be adjusted by changing the size of the cavity 111a and the second ratio.

[0051] In order to conveniently accommodate the second glass 112, the width of the cavity 111a (the dimension along the length direction of the vehicle) should be larger than the second glass 112. In other words, the cavity 111a has only one opening at the top, and is closed in other directions. Such a design can avoid the entry of foreign matter due to the provision of a side opening, and also facilitates the sealing between the first glass 111 and the second glass 112. In some embodiments, a transparent seal (not shown in the figure) can be provided on the top of the first glass 111, surrounding the opening of the cavity 111a. The transparent seal is fixedly connected to the first glass 111, and the transparent seal wraps the outer periphery of the second glass 112, sealing the gap between the second glass 112 and the cavity 111a, and preventing rainwater, dust, and debris from entering the cavity 111a of the first glass 111.

[0052] Since the second glass 112 is installed in the first glass 111, when the first glass 111 is raised or lowered, the first glass 111 can drive the second glass 112 to be raised or lowered together. Since the second glass 112 has an independent driving member, the second glass 112 can also be raised or lowered independently relative to the first glass 111. Therefore, the vehicle door glass lifting system 100 specifically has the following three glass movement modes:

[0053] Mode 1: The second glass 112 is stationary relative to the first glass 111, and the first glass 111 drives the second glass 112 to rise and fall together. In this mode, the second lifting drive 130 does not work, and only the first lifting drive 120 operates.

[0054] Mode 2: The first glass 111 is stationary (relative to the door body 200), and the second glass 112 is independently raised and lowered. In this mode, the first lifting drive 120 does not work, and only the second lifting drive 130 operates.

[0055] Mode three, the second glass 112 is raised and lowered relative to the first glass 111, and the first glass 111 is raised and lowered at the same time. In this mode, both the first lifting drive 120 and the second lifting drive 130 are in operation, and the door glass can be raised and lowered quickly. When the height dimension of the first glass 111 exposed outside the window sill line 210 is the same as the height dimension of the second glass 112, and the lifting speed of the first glass 111 is the same as the lifting speed of the integral glass of the prior art, compared with the integral glass of the prior art, the time required for the door glass of the present application to be lowered to the bottom by one button is only half of the movement time required for the integral glass of the prior art.

[0056] The first glass 111 and the second glass 112 are both transparent glass, and the materials, thicknesses, and strengths of the first glass 111 and the second glass 112 can be set to be different. In some embodiments, considering that the thickness of the cavity wall portion of the cavity 111a of the first glass 111 is relatively thin, the first glass 111 is made of a material with a higher strength than that of the second glass 112, and the second glass 112 is ordinary tempered glass. In some embodiments, the thickness of the outer cavity wall of the cavity 111a can also be set to be greater than the thickness of the inner cavity wall, so that the side of the first glass 111 facing the outside of the vehicle is stronger.

[0057] See also Figure 8 In some embodiments, the first glass 111 and / or the second glass 112 is provided with a transparent display screen 140, which can be used as an information display to display visual information or animations such as weather, temperature, humidity, and schedule, thereby creating more multimedia space for passengers. The transparent display screen 140 can be a transparent OLED display screen, a LED transparent screen, an LCD transparent screen, etc. The transparent display screen 140 can be an independent component, embedded in the first glass 111 and / or the second glass 112, or the first glass 111 and / or the second glass 112 can be used as a glass substrate for the transparent display screen 140.

[0058] Figure 8 In the embodiment shown, the first glass 111 is provided with a transparent display screen 140. When the passenger slightly opens the window, the first glass 111 remains stationary, making it convenient for the passenger to view the content displayed on the transparent display screen 140 ( Figure 8 The display content shown is date, weather information, etc.), and only the second glass 112 is raised and lowered. Since the second glass 112 is transparent glass, it does not affect the display function of the transparent display screen 140. Furthermore, the transparent display screen 140 can also be arranged on the inner wall of the cavity 111a of the first glass 111, reducing the influence of the raising and lowering of the second glass 112 on the visual effect of the transparent display screen 140.

[0059] The first lifting driving member 120 is used to drive the first glass 111 to rise and fall. The first lifting driving member 120 can adopt a mature glass lifter (manual glass lifter or electric glass lifter) in the technology. Fig. 9, shows a schematic diagram of the structure of the first lifting drive member 120 in some embodiments. The first lifting drive member 120 includes a driving component 121, at least one guide rail 122, and a bracket 123 that slides with the guide rail 122. The driving component 121 includes a motor, a reducer, and a transmission mechanism. The motor usually adopts a DC motor, which has the characteristics of high torque and low speed, and is suitable for the load requirements of glass lifting. The output speed of the motor is high but the torque is small, so it is necessary to reduce the speed and increase the torque through a reducer. The reducer generally adopts gear transmission or worm gear transmission. The transmission mechanism transmits the power of the motor to the bracket 123. The transmission mechanism usually has a rope pulley type ( Fig. 9 Shown are rope pulley type window lifts), flexible shaft type and fork arm type.

[0060] The driving component 121 and each guide rail 122 are mounted on the inner door panel of the door body 200. The bracket 123 is fixedly connected to the first glass 111. A convex portion 1111 may be provided at the bottom of the first glass 111, and the convex portion 1111 is fixedly connected to the bracket 123. The bracket 123 is slidably matched with the guide rail 122 and slides up and down along the guide rail 122. In some embodiments, two guide rails 122 are provided, and the two guide rails 122 are spaced apart along the length direction of the door, and two corresponding brackets 123 are also provided, such as Fig. 9 shown.

[0061] The second lifting drive 130 is used to drive the second glass 112 to rise and fall. The second lifting drive 130 can drive the second glass 112 to rise and fall by pneumatic, hydraulic or mechanical transmission. As an implementation scheme, the second lifting drive 130 includes a power unit and a transparent driving rod. The driving rod can be movably extended into the first glass 111 and connected to the second glass 112. The power unit drives the second glass 112 to rise and fall relative to the first glass 111 through the driving rod. The driving rod can be a glass rod, the upper end of the driving rod is connected to the second glass 112 or is integrally formed with the second glass 112, and the lower end of the driving rod is connected to the power unit by transmission. The power unit can be a gear rack driven by a motor, a lead screw nut driven by a motor, an electric telescopic rod, a hydraulic cylinder, a pneumatic cylinder, etc.

[0062] As another embodiment, the second lifting drive member 130 includes a power unit and a storage unit for storing a fluid medium, and the power unit, the storage unit and the cavity 111a of the first glass 111 are interconnected. The fluid medium is a transparent medium, which can be water, oil, air, nitrogen, etc. The fluid medium is usually a colorless transparent medium. In some embodiments, the fluid medium can also be set as a colored transparent medium. For example, a small amount of pigment can be added to water to make the fluid medium have a certain color, so that the window glass also has a certain decorative effect. The power unit can be a pump or a motor.

[0063] See also Figure 1In some embodiments, the second lifting drive member 130 adopts a hydraulic solution, including a liquid storage tank 131 and a pipe 132. The liquid storage tank 131 is arranged on the inner panel of the vehicle door, and the liquid storage tank 131 has a built-in motor (not visible in the figure). The first glass 111 is provided with at least one channel 111b connected to the cavity 111a, and the liquid storage tank 131 is connected to the channel 111b through the pipe 132. The controller controls the motor inside the liquid storage tank 131 to provide transparent liquid to the cavity 111a of the first glass 111 or to extract transparent liquid from the cavity 111a of the first glass 111. The opening of the channel 111b can be set on the convex portion 1111 of the first glass 111, so the number of channels 111b can be the same as the number of convex portions 1111.

[0064] In some embodiments, the liquid storage tank 131 is connected to the door inner panel of the door body 200 and is located between the two guide rails 122. The pipe 132 is movably arranged in the guide rail 122 and the bracket 123. The pipe 132 is a hose. The pipe 132 penetrates into the guide rail 122 from the lower part of the guide rail 122 and penetrates into the bracket 123, thereby communicating with the opening of the channel 111b. When the second glass 112 needs to be extended from the first glass 111, the controller controls the motor to rotate forward, so that the transparent liquid in the liquid storage tank 131 enters the cavity 111a from the channel 111b through the pipe 132, and pushes the second glass 112 to extend from the first glass 111. Fig. 7A When the second glass 112 needs to be retracted toward the first glass 111, the controller controls the motor to reverse, and the transparent liquid in the cavity 111a is pumped into the liquid storage tank 131 through the channel 111b and the pipe 132, so that a negative pressure is formed in the cavity 111a. Under the action of the air pressure, the second glass 112 is retracted into the first glass 111, as shown in FIG. Figure 7B shown.

[0065] In some embodiments, the door glass lifting system 100 also includes a controller, which can be a main control board independently configured for the door glass lifting system 100 , or a vehicle controller of the vehicle on which the door glass lifting system 100 is installed can be used as the controller of the door glass lifting system 100 .

[0066] The second embodiment of the present application provides a door glass lifting method, which is implemented based on the door glass lifting system 100 of any embodiment of the first aspect. For example, the control method can be applied to the main control board of the door glass lifting system 100 of the above embodiment of the present application, or the vehicle controller of the vehicle equipped with the door glass lifting system 100 of the above embodiment. In other embodiments, the control method can also be executed by other devices that communicate with the vehicle controller, for example: remote control through mobile phones, computers, tablet computers and other devices, and the present application does not limit the implementation methods of other devices and the execution subjects of each embodiment.

[0067] Please combine Figure 1 The vehicle door glass lifting method includes a window opening step and a window closing step. The window opening step includes: in response to the window opening signal, controlling at least one of the first lifting drive member 120 and the second lifting drive member 130 to operate so that the first glass 111 and / or the second glass 112 are lowered relative to the door body 200. The window closing step includes: in response to the window closing signal, controlling at least one of the first lifting drive member 120 and the second lifting drive member 130 to operate so that the first glass 111 and / or the second glass 112 are raised relative to the door body 200.

[0068] The glass assembly 110 of the door glass lifting system 100 adopts a mother-and-child glass structure, so at least one of the first glass 111 and the second glass 112 is lowered relative to the door body 200 to open the window or expand the window range. Similarly, at least one of the first glass 111 and the second glass 112 is raised relative to the door body 200 to close the window or reduce the window range. For frameless doors, the door glass needs to be lowered a little when opening the door to release the pressure on the sealing strip. Therefore, the above window opening steps can also be used to release the pressure on the sealing strip when opening the door.

[0069] In some embodiments, the window opening signal includes a first window opening signal and a second window opening signal, wherein the first window opening signal is a one-key-down window opening signal, reflecting that the user wants the door glass to be completely lowered; the second window opening signal is a half-opening signal, reflecting that the user wants the door glass to be only partially opened. Then the window opening step can be performed as follows:

[0070] In response to the first window opening signal, the first lifting drive member 120 and the second lifting drive member 130 are both controlled to operate so that the first glass 111 is lowered relative to the door body 200, and the second glass 112 is lowered relative to the first glass 111. In response to the second window opening signal, the first lifting drive member 120 or the second lifting drive member 130 is controlled to operate so that the first glass 111 or the second glass 112 is lowered relative to the door body 200.

[0071] In the process that the first glass 111 descends relative to the door body 200 and the second glass 112 descends relative to the first glass 111, the descending speed of the first glass 111 and the descending speed of the second glass 112 may be the same or different. In some embodiments, the descending speed of the first glass 111 is lower than the descending speed of the second glass 112, and the second glass 112 descends quickly, which can shorten the window opening time.

[0072] Since the first glass 111 needs to support the second glass 112 to move simultaneously when it moves, the energy required to drive the first glass 111 to move is greater than the energy required to drive the second glass 112 to move. In some embodiments, in response to the second window opening signal, the controller controls the second lifting drive member 130 to operate so that the second glass 112 descends relative to the door body 200, while the first glass 111 remains stationary, thereby reducing the power consumption of the door glass lifting and lowering.

[0073] The window opening signal can be triggered by the passenger pressing a button. For example, if the passenger presses the glass button for more than 2 seconds, the first window opening signal is triggered; if the passenger presses the glass button (pressing time is less than 2 seconds), the second window opening signal is triggered. Or, if the passenger presses the glass button vigorously, the glass button moves downward by a large displacement, triggering the first window opening signal; if the passenger presses the glass button lightly, the glass button moves downward by a small displacement, triggering the second window opening signal. It is also possible to set two glass keys on the car door: a full window opening key and a half window opening key. When a member presses the full window opening key, the first window opening signal is triggered; if the passenger presses the half window opening key, the second window opening signal is triggered. It should be understood that the action of pressing a button is not limited to pressing a button, but can also be a button that touches the touch screen. In some embodiments, the window opening command can also be issued by voice, and the first window opening signal or the second window opening signal is generated according to different window opening commands. More triggering methods of the window opening signal are not exhaustive here.

[0074] In some embodiments, the window closing signal includes a first window closing signal and a second window closing signal, wherein the first window closing signal is a one-key top window closing signal, reflecting that the user wants the door glass to be completely closed; the second window closing signal is a half window closing signal, reflecting that the user wants the door glass to be only partially closed. Then the window closing step can be performed as follows:

[0075] In response to the first window closing signal, the first lifting drive 120 and the second lifting drive 130 are both controlled to operate so that the first glass 111 rises relative to the door body 200, and the second glass 112 rises relative to the first glass 111. In response to the second window closing signal, the first lifting drive 120 or the second lifting drive 130 is controlled to operate so that the first glass 111 or the second glass 112 rises relative to the door body 200.

[0076] In the process that the first glass 111 rises relative to the door body 200 and the second glass 112 rises relative to the first glass 111, the rising speed of the first glass 111 and the rising speed of the second glass 112 may be the same or different. In some embodiments, the rising speed of the first glass 111 is lower than the rising speed of the second glass 112, and the second glass 112 rises quickly, which can shorten the window closing time.

[0077] Since the first glass 111 needs to support the second glass 112 to move simultaneously when it moves, the energy required to drive the first glass 111 to move is greater than the energy required to drive the second glass 112 to move. In some embodiments, in response to the second window closing signal, the controller controls the second lifting drive member 130 to operate so that the second glass 112 rises relative to the door body 200, while the first glass 111 remains stationary, thereby reducing the power consumption of the door glass lifting and lowering.

[0078] The window closing signal can be triggered by the passenger pressing a button. For example, if the passenger lifts the glass button for more than 2 seconds, the first window closing signal is triggered; if the passenger lifts the glass button slightly (pressing time is less than 2 seconds), the second window closing signal is triggered. Alternatively, the passenger pulls the glass button vigorously, the glass button is lifted up with a large displacement, triggering the first window closing signal; the passenger pulls the glass button lightly, the glass button is lifted up with a small displacement, triggering the second window closing signal. It is also possible to set two glass keys on the car door: a full window closing key and a half window closing key. When a member presses the full window closing key, the first window closing signal is triggered; when the passenger presses the half window closing key, the second window closing signal is triggered. It should be understood that the action of pressing a button is not limited to pressing a button, but can also be touching a button on a touch screen. In some embodiments, a window closing command can also be issued by voice, and a first window closing signal or a second window closing signal is generated according to different window closing commands. More triggering methods for the window closing signal are not exhaustive here.

[0079] In certain embodiments, in the window closing step, when the door glass rises to the last section, for example, the top of the glass assembly 110 is less than a set distance (for example, 10 mm) from the window sealing strip, only the second lifting drive 130 is controlled to operate, so that the second glass 112 rises relative to the door body 200, and the second lifting drive 130 is hydraulically driven to slowly raise the second glass 112. The rising speed of the second glass 112 is 70±20 mm / s, so that the door glass can be softly stopped, reducing the impact sound of the door glass hitting the window sealing strip.

[0080] In some embodiments, the door glass lifting method also has an anti-pinch function. In the window closing step, when the anti-pinch condition is met, the second lifting drive 130 is controlled to operate so that the second glass 112 is lowered relative to the first glass 111. When the anti-pinch condition is not met, the window closing step is performed normally. In some embodiments, the anti-pinch condition can be an anti-pinch force ≥ N, and the anti-pinch range is ≤X from the top, where N and X are both set values. That is, when the rising resistance of the glass assembly 110 is ≥ N, and the top of the glass assembly 110 is ≤X from the window sealing strip, the anti-pinch signal is triggered.

[0081] See also Fig.12 , shows a logic block diagram of the window closing step of one-key window closing in a certain implementation scheme. In this embodiment, the second glass 112 is hydraulically driven. The window closing step specifically includes the following steps:

[0082] In response to the first window closing signal, the first lifting drive 120 and the second lifting drive 130 are controlled to operate so that the second glass 112 rises relative to the first glass 111. After the second glass 112 rises into place, the first glass 111 drives the second glass 112 to rise relative to the door body 200.

[0083] During the rising process of the first glass 111 and the second glass 112, it is determined whether the anti-pinch condition is met.

[0084] When the anti-pinch condition is met, the second lifting drive member 130 is controlled to run in the reverse direction, so that the second glass 112 is lowered relative to the first glass 111 until the anti-pinch condition is no longer met.

[0085] When the anti-pinch condition is not met, the window closing step continues.
