[0002] In vehicle design, ensuring that the driver has an open and less obstructed field of view is one of the key factors to improve driving safety and user experience. The lateral field of view of the vehicle, especially the blind area on both sides of the vehicle cab, is crucial to the driver's decision when changing lanes, turning or parking.

The first front plate and the second front plate of the blind-filling window assembly are arranged to extend along a first line of sight direction, and the first bottom plate and the second bottom plate are arranged to extend along a second line of sight direction. The first line of sight direction and the second line of sight direction intersect at a same preset eye point. The preset eye point is the position of the eyes of a driver with a standard height and in a standard sitting posture when looking at the blind-filling window from a driving position. The first line of sight and the second line of sight both refer to the line of sight from the preset eye point. The first front plate and the second front plate are arranged to be inclined along the first line of sight direction, and the first bottom plate and the second bottom plate are arranged to be inclined along the second line of sight direction. Thus, an outwardly expanding opening is formed in the direction from inside to outside, the effective field of view area of the blind-filling window assembly is increased, and the ability of the driver to observe the outside through the blind-filling window is improved. Moreover, the outer shielding frame and the inner shielding frame can shield and limit the space and components outside the outer shielding frame and outside the inner shielding frame in the circumferential direction of the outer shielding frame and the inner shielding frame between the outer light-transmitting plate and the inner light-transmitting plate. The cavity structure of the vehicle door cannot be seen from the inside and outside of the vehicle door, the blind-filling window is less shielded by the inner structure of the vehicle door, the appearance of the vehicle door is beautiful, and the quality is strong.

Compared with the blind-filling window with a single light-transmitting plate, the inside of the light-transmitting plate is prone to fogging due to the temperature difference T between the inside and the outside. The present embodiment adopts a double-layer structure, and the space between the outer light-transmitting plate and the inner light-transmitting plate is equivalent to a sandwich layer. The temperature difference T1 between the outside of the outer light-transmitting plate and the sandwich layer, the temperature difference T2 between the sandwich layer and the inside of the inner light-transmitting plate, and T1+T2=T. The temperature difference is reduced, and the blind-filling window is less affected by the environment, the field of view of the blind-filling window remains clear, the blind-filling window is less shielded, and the effective field of view area of the blind-filling window is increased.

[0058] The blind-filling window field-of-view optimization method determines the Y-direction installation range of the lifter installation plate according to the door profile and the glass body operation profile, and determines the Y-direction inner boundary of the outer shielding frame and the Y-direction outer boundary of the inner shielding frame according to the glass body operation profile, determines the outer limit position of the upper boundary of the inner window assembly and the inner limit position of the upper boundary of the inner window assembly according to the preset upper boundary of the inner trim plate, the connection structure of the inner window assembly and the door, and the Y-direction installation range of the lifter installation plate, then determines the lower boundary of the inner window assembly according to the door profile, the Y-direction installation range of the lifter installation plate and the connection structure of the inner window assembly and the inner trim plate, determines the front boundary of the outer shielding frame and the rear boundary of the outer shielding frame according to the door profile, the connection structure of the outer shielding frame and the door outer plate and the Y-direction installation range of the lifter installation plate, and finally checks the field-of-view volume, through the above steps, the arrangement of the blind-filling window on the door not only reduces the blind area, but also fully considers the compatibility of the door structure, the interior layout and the glass lifting assembly, optimizes and expands the up-down and front-rear field-of-view range of the blind-filling window assembly, reduces the occupation of the door structure, the interior layout and the glass lifting assembly on the field-of-view of the blind-filling window assembly, and improves the effective field-of-view range of the driver.

Moreover, the embodiment is designed as a double-layer structure matched with the inner window assembly 2 and the outer window assembly 1, and the lifting channel 3 is formed to avoid the position of the glass body 52 and other lifting components on the door, thereby reducing the position interference.

[0083] Since the blind-filling window assembly is included, the door of the embodiment of the present application has all the advantages and beneficial effects of the above-mentioned embodiments, which will not be repeated here.

[0084] As shown in Figures 3 to 5 The embodiment of the third aspect of the present application provides a vehicle, which comprises a cab body and two doors as in any of the above-mentioned embodiments. The door bodies 4 of the two doors are movably connected with the cab body, and the two doors are oppositely arranged along the left-right direction of the vehicle.

[0085] Since the door is included, the vehicle of the embodiment of the present application has all the advantages and beneficial effects of the above-mentioned embodiments, which will not be repeated here.

[0086] As shown in Figures 3 to 6 The embodiment of the fourth aspect of the present application provides a blind-filling window field-of-view optimization method for optimizing the field of view of the blind-filling window assembly on the door. The blind-filling window field-of-view optimization method specifically comprises the following steps:

[0087] Step S100, acquiring a door surface, a glass body running surface, and a preset eye point;

[0088] The door profile refers to the contour shape of the outside and inside of the door, including at least the shape design of the outer door panel and the inner door panel. The glass body running profile refers to the trajectory surface followed by the vehicle window glass body during lifting, which is related to the arrangement of the blind window and the field of view. The eye point refers to the position of the driver's eyes. The preset eye point is the position of the driver's eyes when sitting in the driving position with a standard sitting posture and looking at the blind window based on a standard height. The field of view is analyzed from this position to ensure that the driver can obtain a better field of view.

[0089] Step S200, determining the Y-direction installation range of the lifter mounting plate according to the door profile and the glass body running profile;

[0090] The Y-direction installation range of the lifter mounting plate refers to the installation limit position of the lifter mounting plate in the inside and outside direction of the door. Y-direction also refers to the width direction of the vehicle. On the one hand, the lifter mounting plate cannot be too close to the glass body running profile to ensure the operation space and structural safety of the glass body. On the other hand, the lifter mounting plate cannot be too close to the inside of the door, which affects the arrangement of the interior panel and other internal components and affects the driving space.

[0091] Step S300, determining the Y-direction inner boundary of the outer shielding frame and the Y-direction outer boundary of the inner shielding frame according to the glass body running profile;

[0092] The outer shielding frame and the inner shielding frame are arranged on the inside and outside of the glass body respectively. The Y-direction inner boundary of the outer shielding frame and the Y-direction outer boundary of the inner shielding frame are further selected by the glass body running profile to avoid interference with the running glass body and to maximize the field of view. The boundary position needs to maintain a certain distance from the running trajectory surface of the glass body to ensure sufficient space.

[0093] Step S400, presetting the upper boundary of the interior panel according to the door profile and the preset eye point;

[0094] This step involves presetting the upper boundary position of the interior panel to meet the ergonomics requirements, which needs to ensure that the interior panel does not block the driver's field of view from the preset eye point.

[0095] Step S500, determining the outer limit position and the inner limit position of the upper boundary of the interior window assembly according to the preset upper boundary of the interior panel, the connection structure of the interior window assembly and the door, and the Y-direction installation range of the lifter mounting plate;

[0096] The inner window assembly upper boundary is selected from a position range between the outer limit position and the inner limit position of the inner window assembly upper boundary, the inner window assembly upper boundary is determined according to the preset interior trim plate upper boundary, the connection structure of the inner window assembly and the interior trim plate and the arrangement position of the lifter mounting plate, the obstruction of the interior trim plate to the field of view of the inner window assembly is reduced, and thus the field of view range is optimized and increased.

[0097] In step S600, the inner window assembly lower boundary is determined according to the vehicle door profile, the Y-direction mounting range of the lifter mounting plate and the connection structure of the inner window assembly and the interior trim plate, a field of view is made from the preset eye point to the inner window assembly lower boundary, and a first bottom plate profile and a second bottom plate profile are formed.

[0098] The Y-direction mounting range of the lifter mounting plate is a range in which the lifter mounting plate can be mounted, the vehicle door inner panel has a draft angle, the closer the position of the lifter mounting plate to the vehicle outer direction, the closer the starting point of the lower boundary of the inner window assembly, and thus the field of view area is directly reduced, and therefore, the mounting position of the lifter mounting plate can be determined based on the principle that the lifter mounting plate is as close as possible to the vehicle interior, and then the lower boundary of the inner window assembly is determined in combination with the vehicle door profile and the connection structure of the inner window assembly and the interior trim plate, a field of view is made from the preset eye point to the lower boundary of the inner window assembly, and the first bottom plate profile and the second bottom plate profile formed can greatly expand the lower field of view of the blind window.

[0099] In step S700, the front boundary of the outer shielding frame and the rear boundary of the outer shielding frame are determined according to the vehicle door profile, the connection structure of the outer shielding frame and the vehicle door outer panel and the Y-direction mounting range of the lifter mounting plate, a field of view is made from the preset eye point to the front boundary of the outer shielding frame, a first front plate profile and a second front plate profile are formed, a field of view is made from the preset eye point to the rear boundary of the outer shielding frame, a first rear plate profile and a second rear plate profile are formed.

[0100] The mounting position of the lifter mounting plate is selected from the Y-direction mounting range of the lifter mounting plate, the connection structure of the outer shielding frame and the vehicle door outer panel is ensured to stably connect the outer shielding frame and the vehicle door outer panel in combination with the vehicle door profile, the front boundary of the outer shielding frame is determined, a field of view is made from the preset eye point to the front boundary of the outer shielding frame, the first front plate profile and the second front plate profile are formed, so that the first front plate and the second front plate both extend along the line of sight direction of the preset eye point, and the front field of view of the blind window is expanded. Similarly, the mounting position of the lifter mounting plate is selected from the Y-direction mounting range of the lifter mounting plate, the connection structure of the outer shielding frame and the vehicle door outer panel is ensured to stably connect the outer shielding frame and the vehicle door outer panel in combination with the vehicle door profile, the rear boundary of the outer shielding frame is determined, the first rear plate profile and the second rear plate profile are formed, so that the first rear plate and the second rear plate both extend along the line of sight direction of the preset eye point, and the rear field of view of the blind window is expanded.

[0101] Step S800, according to the multiple lifter mounting plate Y direction installation positions selected in the mounting range of the lifter mounting plate Y, the multiple inner window assembly upper boundary positions selected in the inner window assembly upper boundary outer limit position to the inner window assembly upper boundary inner limit position, and the inner window assembly lower boundary, the outer shielding frame front boundary and the outer shielding frame rear boundary selected at different lifter mounting plate Y direction installation positions, a plurality of visual field volume combinations are obtained in the range surrounded by the inner shielding frame upper boundary corresponding to the inner window assembly upper boundary position, the inner shielding frame lower boundary corresponding to the inner window assembly lower boundary and the outer shielding frame front boundary and the outer shielding frame rear boundary.

[0102] Step S900, check the visual field volume, select the outer shielding frame circumferential boundary position and the visual angle corresponding to the maximum visual field volume combination and the inner shielding frame circumferential boundary position and the visual angle, that is, by calculating and comparing the visual field volumes under different layouts, the visual field volume refers to the external environment volume that the driver can clearly see through the blind filling window assembly from the preset eye point, and the blind filling window layout scheme capable of providing the maximum visual field volume is selected, including the circumferential boundary position and the visual angle of the outer window assembly 1 and the inner window assembly, so as to realize the optimization of the visual field.

[0103] The above steps can ensure that the arrangement of the blind filling window on the door not only reduces the blind area, but also fully considers the compatibility of the door structure, the interior layout and the glass lifting assembly, optimizes and expands the up-down and front-rear visual field range of the blind filling window assembly, reduces the occupation of the door structure, the interior layout and the glass lifting assembly on the visual field of the blind filling window assembly, improves the effective visual field range of the driver, and solves the problem that the internal structure of the door easily reduces the effective visual field area of the blind filling window in the related art.

[0104] Optionally, by using three-dimensional drawing software or visual field analysis software, the visual line from the preset eye point can be simulated to intersect with the shapes of the door, the blind filling window assembly, the interior panel and the glass lifting assembly to form different visual field surfaces. The volumes of these visual field surfaces in the three-dimensional space are calculated to find the layout combination capable of providing the maximum visual field volume, including the circumferential boundary position and the visual angle of the outer shielding frame and the inner shielding frame. Multiple iterations can be performed until the optimal solution is found.

[0105] In some embodiments, after determining the inner window assembly upper boundary outer limit position and the inner window assembly upper boundary inner limit position in step S500, the blind filling window visual field optimization method further comprises:

[0106] a first visual field surface is made from the preset eye point to the inner window assembly upper boundary outer limit position, and a second visual field surface is made from the preset eye point to the inner window assembly upper boundary inner limit position, and it is checked whether the interior panel upper boundary blocks the first visual field surface and the second visual field surface;

[0107] If the upper boundary of the interior trim panel is above the first view surface, the upper boundary of the interior trim panel does not block the view of the interior window assembly, and the position of the upper boundary of the interior trim panel can be maintained;

[0108] If the upper boundary of the interior trim panel is between the first view surface and the second view surface, the upper boundary of the interior trim panel blocks the first view surface, indicating that the interior trim panel blocks the driver's line of sight and affects the view of the supplemental window. At this time, a new first view surface needs to be formed from the view surface from the preset eye point to the upper boundary of the interior trim panel, or the upper boundary of the interior trim panel needs to be adjusted upward until the upper boundary of the interior trim panel after the adjustment is located above the first view surface. This new first view surface will accurately reflect the actual impact of the upper boundary of the interior trim panel on the view, and based on this new first view surface, the degree of blocking of the interior trim panel is evaluated and appropriate adjustments are made, such as reducing the height of the interior trim panel or modifying its shape, to avoid blocking or minimize the view blocking.

[0109] Through the above steps, the arrangement of the interior trim panel can be systematically checked and optimized, reducing unnecessary restrictions on the view range of the supplemental window, thereby improving the driving safety of the vehicle. Through the check, precise adjustment and optimization can be facilitated.

[0110] If the upper boundary of the interior trim panel is below the second view surface, the view surface from the preset eye point to the upper boundary of the interior trim panel is the upper view surface, and the Y-direction position of the interior window assembly has no effect on the upper view. However, this situation will excessively block the view of the supplemental window and should be avoided.

[0111] In some embodiments, step S200 includes determining the Y-direction installation range of the lifter mounting plate based on the door profile and the glass body operation profile, comprising:

[0112] determining the door outer panel profile, the door inner panel profile, and the door glass partition based on the door profile;

[0113] The door glass partition refers to the division of the door glass into different areas according to design requirements, which is usually done to meet different functional requirements.

[0114] determining the door outer handle position based on the door outer panel profile, the door inner panel profile, and the door glass partition;

[0115] The specific position of the door outer handle on the door outer panel is determined based on the ergonomic layout and modeling input. This step needs to ensure that the handle position is convenient for operation and does not interfere with the door window glass during lifting.

[0116] adjusting the glass body operation profile based on the door outer handle position;

[0117] If the distance between the position of the outside handle of the door and the initial design of the glass body running profile is too small, it may affect the smoothness and safety of the glass body lifting. Therefore, it is necessary to adjust the running track of the glass body to ensure that the minimum distance between the glass body and the outside handle of the door is equal to or greater than 10 mm, and the maximum distance between the running profile of the glass body after adjustment and the running profile of the glass body input by modeling should be less than or equal to 1 mm to maintain the consistency and aesthetics of the design. According to the adjustment of the glass body running profile according to the position of the outside handle of the door, it is ensured that there is enough gap between the glass body and the outside handle of the door, which can further optimize the glass body running profile and avoid unnecessary structural obstruction to create conditions for the increase of the blind window view. By fine-tuning the glass body running profile, the influence on the blind window view can be minimized while maintaining the smoothness of the window operation.

[0118] According to the adjusted glass body running profile and the door glass partition, the support structure and support position of the door to the glass body are determined;

[0119] The support structure of the door to the glass body refers to the structure of the glass guide rail and the window sliding groove, and the position of the guide rail bracket of the glass lifter is determined according to the structure and position of the glass guide rail and the window sliding groove. The minimum distance between the guide rail bracket of the glass lifter and the window sliding groove is greater than or equal to 20 mm. The support structure and support position directly affect the installation position of the glass lifter, and then affect the glass body running profile. By optimizing the support structure and support position, it can be ensured that the glass body will not be restricted by the internal structure during lifting, providing more view space for the blind window.

[0120] According to the support structure and support position of the door to the glass body, the position of the glass lifter is determined;

[0121] By reasonably arranging the glass lifter inside the door, it can be ensured that the glass body avoids interference with the internal structure during lifting, and at the same time, the optimized layout of the glass lifter can also reduce the influence on the view of the inner window assembly, realizing the maximization of the view.

[0122] According to the door inner panel profile and the position of the glass lifter, the installation range of the lifter mounting plate in Y direction is determined, wherein the position of the lifter mounting plate corresponding to the position of the glass lifter closest to the outer panel of the door is the outer limit position of the lifter mounting plate in Y direction, the position of the lifter mounting plate corresponding to the position farthest from the outer panel of the door that can be provided by the door inner panel is the inner limit position of the lifter mounting plate in Y direction, and the position closest to the inside is the limit assembly position that can be provided by the door inner panel after considering sealing, structural stiffness and stamping process. The placement position of the lifter mounting plate can also be combined with the arrangement of other parts inside the door, and the material can also be plastic mold parts as much as possible, so that the arrangement of internal parts is more flexible. The final position of the lifter mounting plate can be selected as close to the inside as possible.

[0123] The mounting range of the lifter mounting plate in the Y direction determines the available space of the inner window assembly, and directly affects the size of the field of view. Selecting the position of the lifter mounting plate at the limit position closest to the inner panel of the door, that is, the Y direction limit position of the lifter mounting plate, can maximize the avoidance of the obstruction of the field of view, and increase the field of view of the blind window. At the same time, by ensuring that there is enough distance between the lifter mounting plate and the window sliding groove, mechanical interference can be avoided, and the smoothness of the glass body lifting can be ensured.

[0124] In this way, the embodiment optimizes the internal structure of the door, adjusts the glass lifting track, and determines the position of the lifter mounting plate, while ensuring the functionality and safety of the door, to minimize the obstruction of the driver's view by the internal structure, so that the driver can have a wider field of view, reduce the blind area, and improve driving safety.

[0125] In some embodiments, step S300, determining the Y direction inner boundary of the outer shielding frame and the Y direction outer boundary of the inner shielding frame according to the glass body operation profile, comprises:

[0126] The inner end of the outer shielding frame is kept at a first preset distance from the glass body operation profile;

[0127] The outer end of the inner shielding frame is kept at a second preset distance from the glass body operation profile;

[0128] The first preset distance and the second preset distance are in the range of 5-10 mm, for example, the first preset distance and the second preset distance can be selected as 7 mm, which can provide sufficient running space for both sides of the glass body, and can also avoid the situation that the outer shielding frame and the inner shielding frame are too far apart, causing the internal components of the door to enter the gap between the outer shielding frame and the inner shielding frame and enter the chamber between the outer shielding frame and the inner shielding frame, reducing the influence of the internal components of the door on the field of view of the blind window.

[0129] In some embodiments, step S400, presetting the upper boundary of the interior trim panel according to the door profile and the preset eye point, comprises:

[0130] According to the door profile, determining the lower boundary of the window and the position of the door inner and outer switch;

[0131] Based on the principles that the door inner and outer switch position is as close as possible to the upper boundary of the interior trim panel, the size of the door inner and outer switch is as small as possible, and the Y direction size of the interior trim panel is as thin as possible, the upper boundary of the interior trim panel is preset according to the lower boundary of the window and the human-machine field of view requirement of the preset eye point.

[0132] The lower boundary of the vehicle window refers to the lowest boundary of the vehicle window, and the inside and outside door handle refers to the door handle switch and the inside opening handle. The position of the door handle switch and the position of the outside handle can be the same position, or the door handle switch and the outside handle can be in transmission connection, and a certain spacing can be provided therebetween. In this embodiment, the inside and outside door handle is arranged according to the position of the upper boundary of the interior trim panel, the Z-direction height dimension of the inside and outside door handle is minimized, and the arrangement position is as close to the upper boundary of the interior trim panel as possible. The pull wire of the inside opening handle is arranged at the rear part of the inside opening handle, the Z-direction dimension of the connection structure of the inside opening handle and the interior trim panel is as small as possible, and the overall height of the inside opening handle is not increased. For the vehicle door with a blind window, the inside opening handle can be arranged on the upper surface of the interior trim panel, or the door handle and the inside opening handle can be designed as one part, so as to reduce the Z-direction dimension of the structure of the inside and outside door handle. According to the checking of the human-machine operation space and the arrangement of the interior parts of the vehicle door, the Y-direction dimension of the interior trim panel is minimized. According to the lower boundary of the vehicle window determined by the modeling and the human-machine visual line requirement, the upper boundary of the interior trim panel is preset, that is, the upper boundary of the interior trim panel is determined by the visual line path from the preset eye point. When the driver observes from the preset eye point, a clear and extensive visual field can be obtained, the excessive influence of the upper part of the interior trim panel or the inside and outside door handle on the upper boundary of the blind window is reduced, and the visual field of the blind window is improved.

[0133] In some embodiments, step S500, according to the preset upper boundary of the interior trim panel, the connection structure of the interior window assembly and the interior trim panel, and the Y-direction installation range of the lifter mounting plate, the upper boundary outer limit position of the interior window assembly and the upper boundary inner limit position of the interior window assembly are determined, comprising:

[0134] According to the upper boundary of the vehicle door interior, the connection structure of the interior window assembly and the interior trim panel, the Y-direction inner limit position of the connection structure of the lifter mounting plate and the interior window assembly is determined; wherein the Y-direction inner limit position of the connection structure of the lifter mounting plate and the interior window assembly refers to the limit position of the connection structure of the lifter mounting plate and the interior window assembly in the Y-direction close to the interior, the Y-direction inner limit position of the connection structure of the lifter mounting plate and the interior window assembly needs to consider the profile of the interior trim panel and the connection structure of the interior window assembly and the interior trim panel, reduce the limitation of the vehicle door interior or other vehicle door parts on the installation position of the interior window assembly at this position, and also make the interior shielding frame of the lifter mounting plate and the interior window assembly have enough installation space.

[0135] According to the position of the inner window assembly and the minimum size of the inner window assembly and the lifter mounting plate connecting structure, the Y outward limit position of the lifter mounting plate and the inner window assembly connecting structure is determined; wherein the Y outward limit position of the lifter mounting plate and the inner window assembly connecting structure refers to the limit position of the lifter mounting plate and the inner window assembly connecting structure in the Y direction close to the outside of the vehicle, and the Y outward limit position of the lifter mounting plate and the inner window assembly connecting structure needs to consider the profile of the inner trim panel and the connecting position of the inner shielding frame of the inner window assembly and the glass profile to reduce the position interference of the inner window assembly and the glass profile and the lifter mounting plate. The Y outward limit position of the lifter mounting plate and the inner window assembly connecting structure is mainly constrained by the maximum size of the inner window assembly and the lifter mounting plate connecting structure, so as to ensure that the lifter mounting plate can stably support the inner window assembly even at the outermost position, and at the same time, the position interference between the glass profile and the lifter mounting plate is avoided, and the integrity of the vehicle door internal structure is maintained.

[0136] According to the Y inward limit position of the lifter mounting plate and the inner window assembly connecting structure, the Y outward limit position of the lifter mounting plate and the inner window assembly connecting structure, the profile of the inner trim panel and the size of the connecting structure of the inner window assembly and the inner trim panel, the upper boundary outer limit position of the inner window assembly and the upper boundary inner limit position of the inner window assembly are determined.

[0137] In this way, by the size of the connecting structure of the inner window assembly and the inner trim panel and the position of the connecting structure of the inner window assembly and the lifter mounting plate, the installation and movement range of the upper part of the inner window assembly is reduced, the position interference between the inner window assembly and the inner trim panel or other vehicle door internal structures when the inner window assembly is raised to the highest point is reduced, and the better view of the preset eye point on the upper part of the blind window is also ensured.

[0138] In some embodiments, step S600, according to the vehicle door profile, the Y direction installation range of the lifter mounting plate and the connecting structure of the inner window assembly and the inner trim panel, the lower boundary of the inner window assembly is determined, including:

[0139] According to the connecting structure of the inner trim panel and the vehicle door inner panel and the profile of the vehicle door inner panel, the installation position of the lifter mounting plate and the vehicle door inner panel is determined. This step is based on the vehicle door profile and the vehicle door inner panel profile, and considers the layout of the vehicle door internal structure, especially the connecting structure between the inner trim panel and the vehicle door inner panel, to determine the specific installation position of the lifter mounting plate in the vehicle door interior. The position of the lifter mounting plate needs to ensure that it can be stably installed on the vehicle door inner panel, and at the same time, the interference with other parts of the vehicle door, such as the glass lifter, the inner trim panel, etc. is avoided, and the limitation on the minimum height of the inner window assembly in the vehicle door interior is reduced.

[0140] Based on the principle that the lifter mounting plate is as close as possible to the vehicle door inner panel, the Y inward limit position of the lifter mounting plate is determined, which can reduce the obstruction of the view of the inner window assembly.

[0141] According to the starting position of the lower boundary of the inner window assembly, the mounting size of the lifter mounting plate, and the connection structure of the inner window assembly and the interior trim panel, the lower boundary of the inner window assembly is determined.

[0142] Wherein, according to the connection structure of the interior trim panel and the door inner panel, and the draft angle of the door inner panel, the position of the lifter mounting plate and the mounting surface of the door inner panel is determined, and the Y-direction limit position of the lifter mounting plate is a range, that is, the position closest to the vehicle exterior is the installation limit position of the glass lifter guide rail, and the position closest to the vehicle interior is the limit assembly position provided by the door inner panel after considering sealing, structural stiffness, sealing, and stamping process. Since the door inner panel has a draft angle, the closer the position of the lifter mounting plate to the vehicle exterior direction, the closer the starting position of the lower boundary of the inner window assembly, which directly reduces the field of view area, so the position of the lifter mounting plate should be selected as the limit position closest to the vehicle interior. According to the starting position of the lower boundary of the inner window assembly, the mounting size of the lifter mounting plate, and the connection structure of the inner window assembly and the interior trim panel, such as the size of the quick-release structure fixing member, the lower boundary of the inner window assembly is determined, and a field of view surface is formed from the preset eye point to the lower boundary of the inner window assembly, which can form a first bottom plate profile and a second bottom plate profile, both of which can extend in the line of sight direction of the lower boundary of the inner window assembly, so that the lower part of the blind window has a larger field of view.

[0143] In some embodiments, step S700, according to the door profile, the connection structure of the outer shielding frame and the door outer panel, and the Y-direction mounting range of the lifter mounting plate, the front boundary of the outer shielding frame is determined, including:

[0144] According to the installation parameters of the glass lifter, the motion envelope of the glass lifter and the glass body is made, and the minimum distance between the motion envelope of the glass lifter and the glass body and the outer shielding frame and the minimum distance between the motion envelope of the glass lifter and the glass body and the inner shielding frame are both greater than or equal to 7mm, which can provide sufficient clearance between the two sides of the glass body and the outer shielding frame and the inner shielding frame, reduce positional interference, and avoid the case where the distance between the inner shielding frame and the outer shielding frame is too large, causing the exposure of the internal components of the door.

[0145] According to the connection structure size of the outer shielding frame and the door outer panel and the connection structure size of the inner shielding frame and the lifter mounting plate, the front boundary of the outer shielding frame is determined, so that the front boundary of the outer shielding frame can be selected on the basis of ensuring the stable connection of the outer shielding frame and the door outer panel, and the stable connection of the inner shielding frame and the lifter mounting plate, and the front boundary of the outer shielding frame corresponding to a larger field of view area is selected on this basis, which can further expand the field of view of the blind window.

[0146] The installation parameters of the glass lifter can include, but are not limited to, strength requirements, lightweight requirements and performance requirements of the glass lifter. According to the strength requirements, lightweight requirements and performance requirements of the glass lifter, the guide rails, pulleys and stay wires of the glass lifter are arranged, and the motion envelope of the glass lifter and the glass body is made. Obviously, the above embodiments of the present application are only examples for clearly illustrating the present application, and are not intended to limit the embodiments of the present application.
