[0056] The beneficial effects of the present invention are:

[0057] The present invention provides a blind spot window assembly, a vehicle door, a vehicle and a method for optimizing the visual field of the blind spot window. The first front plate and the second front plate of the blind spot window assembly are both extended along a first visual line direction, the first bottom plate and the second bottom plate are both extended along a second visual line direction, the first visual line direction and the second visual line direction intersect at the same preset eye point, the preset eye point is based on the position of the eyes of a driver of standard height sitting in a standard sitting posture in a driving seat looking at the blind spot window, the first visual line and the second visual line both refer to the visual lines emitted from the preset eye point, that is, the first front plate and the second front plate are tilted along the first visual line direction, the first bottom plate and the second bottom plate are tilted along the second visual line direction, thereby forming a blind spot window assembly from inside to outside. The outwardly expanded opening increases the effective field of view of the blind window assembly and improves the driver's ability to observe the outside world through the blind window. The outer shielding frame and the inner shielding frame can block and limit the space and components outside the circumference of the outer shielding frame and outside the circumference of the inner shielding frame between the outer light-transmitting plate and the inner light-transmitting plate. The inner cavity structure of the door cannot be seen from both the inside and outside of the door, which reduces the obstruction of the field of view of the blind window by the inner structure of the door, and also makes the appearance of the door beautiful and high-quality. In addition, this embodiment is designed as a double-layer structure in which the inner window assembly and the outer window assembly are matched, and the lifting channel is formed to avoid the position of the lifting parts such as the glass body on the door to reduce position interference. Compared with the blind spot window that uses a single layer of light-transmitting plate, the temperature difference between the inside and outside is T, and the inside of the light-transmitting plate is prone to fogging. The present embodiment adopts a double-layer structure, and the outer light-transmitting plate and the inner light-transmitting plate are equivalent to a sandwich. The temperature difference between the outer side of the outer light-transmitting plate and the sandwich is T1, and the temperature difference between the sandwich and the inner layer outside the inner light-transmitting plate is T2, T1+T2=T, which reduces the temperature difference and makes it less likely to fog, reduces the impact of the environment on the field of view of the blind spot window, keeps the field of view of the blind spot window clear, reduces obstruction, and can also increase the effective field of view area of ​​the blind spot window.

[0058] The blind window field optimization method determines the Y-direction installation range of the lifter mounting plate according to the door profile and the glass body running 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 running profile. According to the preset upper boundary of the interior panel, the connection structure between the inner window assembly and the door, and the Y-direction installation range of the lifter mounting plate, 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 are determined. Then, according to the door profile, the Y-direction installation range of the lifter mounting plate, and the connection structure between the inner window assembly and the interior panel, the lower boundary of the inner window assembly is determined. According to the door profile, the connection structure between the outer shielding frame and the door outer panel, and the Y-direction installation range of the lifter mounting plate, the front boundary and the rear boundary of the outer shielding frame are determined, and finally the field of view volume is checked. Through the above steps, the arrangement of the blind spot window on the door not only reduces the blind spot, but also fully considers the compatibility of the door structure, interior layout and glass lifting assembly, optimizes and expands the upper and lower front and rear field of view of the blind spot window assembly, reduces the occupation of the door structure, interior layout and glass lifting assembly on the field of view of the blind spot window assembly, and improves the effective field of view of the driver.

[0076] like Figures 1 to 3 As shown, an embodiment of the first aspect of the present invention provides a blind spot filling window assembly, which includes an outer window assembly 1 and an inner window assembly 2. The outer window assembly 1 includes an outer light-transmitting plate 11 and an outer shielding frame 12, and the outer shielding frame 12 is arranged around the outer light-transmitting plate 11 to block and limit components outside the circumference of the outer light-transmitting plate 11, thereby reducing the blocking of the visual field of the outer light-transmitting plate 11 by other components. The outer light-transmitting plate 11 is used to close the outer opening of the outer shielding frame 12. The outer shielding frame 12 includes a first top plate 121, a first rear plate 122, a first bottom plate 123 and a first front plate 124 which are arranged in sequence along the circumference of the outer light-transmitting plate 11. The first top plate 121 is arranged corresponding to the top position of the vehicle door, the first rear plate 122 is arranged corresponding to the rear position of the vehicle door, the first bottom plate 123 is arranged corresponding to the bottom position of the vehicle door, and the first front plate 124 is arranged corresponding to the front position of the vehicle door, that is, the circumferential contour of the outer shielding frame 12 is similar to the circumferential contour of the vehicle door, which can greatly expand the field of view of the position where the outer light-transmitting plate 11 is located.

[0077] The inner window assembly 2 includes an inner light-transmitting plate 21 and an inner shielding frame 22. The inner shielding frame 22 is arranged in the circumferential direction of the inner light-transmitting plate 21. The inner light-transmitting plate 21 is used to close the inner opening of the inner shielding frame 22. Along the Y direction from the inside to the outside, the inner light-transmitting plate 21, the inner shielding frame 22, the outer shielding frame 12, and the outer light-transmitting plate 11 are arranged in sequence. The inner shielding frame 22 and the outer shielding frame 12 are arranged at intervals. The inner shielding frame 22 and the outer shielding frame 12 are both made of opaque materials. The inner shielding frame 22 includes a plurality of light-transmitting plates 21 and a plurality of light-transmitting plates 11.

[0078] The first front plate 124 and the second front plate 224 are both extended along the first sight line direction, the first bottom plate 123 and the second bottom plate 223 are both extended along the second sight line direction, the first sight line direction and the second sight line direction intersect at the same preset eye point 6, the preset eye point 6 is based on the position of the eyes of a driver of standard height sitting in a standard sitting posture in the driving seat looking at the blind spot window, the first sight line and the second sight line both refer to the sight lines emitted by the preset eye point 6, that is, the first front plate 124 and the second front plate 224 are tilted along the first sight line direction, and the first bottom plate 123 and the second bottom plate 223 are tilted along the second sight line direction, thereby forming an outward expansion opening in the direction from the inside to the outside, thereby increasing the total blind spot window. The effective visual area formed improves the driver's ability to observe the outside world through the blind spot window, and the outer shielding frame 12 and the inner shielding frame 22 can block and limit the space and components outside the circumference of the outer shielding frame 12 and the circumference of the inner shielding frame 22 between the outer light-transmitting plate 11 and the inner light-transmitting plate 21. The inner cavity structure of the door cannot be seen from both the inside and outside of the door, which reduces the obstruction of the blind spot window field by the inner structure of the door, and also makes the appearance of the door beautiful and high-quality. In addition, this embodiment is designed as a double-layer structure in which the inner window assembly 2 and the outer window assembly 1 are matched, and the lifting channel 3 is formed to avoid the position of the lifting parts such as the glass body 52 on the door, thereby reducing position interference. Compared with the blind spot window that uses a single layer of light-transmitting plate, the temperature difference between the inside and outside is T, and the inside of the light-transmitting plate is prone to fogging. The present embodiment adopts a double-layer structure, and the outer light-transmitting plate 11 and the inner light-transmitting plate 21 are equivalent to a sandwich. The temperature difference between the outer side of the outer light-transmitting plate 11 and the sandwich is T1, and the temperature difference between the sandwich and the inner layer outside the inner light-transmitting plate 21 is T2, T1+T2=T, which reduces the temperature difference and makes it less likely to fog, reduces the impact of the environment on the field of vision of the blind spot window, keeps the field of vision of the blind spot window clear, reduces obstruction, and can also increase the effective field of vision area of ​​the blind spot window, solving the problem in the related art that the internal structure of the door easily reduces the effective field of vision area of ​​the blind spot window.

The outer window assembly 1 is arranged on the vehicle door outer panel 41, and the inner window assembly 2 is arranged on the lifter mounting plate 51. There is a spacing between the outer shielding frame 12 of the outer window assembly 1 and the inner shielding frame 22 of the inner window assembly 2 to form a lifting channel 3. The glass lifter 53 is arranged on the periphery of the blind-filling window assembly, and the glass lifter 53 can drive the glass body 52 to perform lifting movement at the lifting channel 3.

[0082] The first front plate 124 and the second front plate 224 are tilted along the first line of sight, and the first bottom plate 123 and the second bottom plate 223 are tilted along the second line of sight, thereby forming an outwardly expanding opening from the inside to the outside, increasing the effective field of view of the blind window assembly, and improving the driver's ability to observe the outside world through the blind window. In addition, the outer shielding frame 12 and the inner shielding frame 22 can block and limit the space and components outside the circumference of the outer shielding frame 12 and outside the circumference of the inner shielding frame 22 between the outer light-transmitting plate 11 and the inner light-transmitting plate 21. The inner cavity structure of the door cannot be seen from both the inside and outside of the door, reducing the obstruction of the blind window field of view by the inner structure of the door, and also making the door beautiful in appearance and high in quality. In addition, this embodiment is designed as a double-layer structure in which the inner window assembly 2 and the outer window assembly 1 cooperate, and by forming a lifting channel 3, the lifting parts such as the glass body 52 on the door can be avoided in position to reduce position interference. Moreover, the present embodiment adopts a double-layer structure, and the outer light-transmitting plate 11 and the inner light-transmitting plate 21 are equivalent to a sandwich layer, which reduces the temperature difference and is not easy to fog, reduces the influence of the environment on the field of view of the blind spot window, keeps the field of view of the blind spot window clear, reduces obstruction, and can also increase the effective field of view area of ​​the blind spot window, so that the driver can not only observe through the window at the glass body 52 on the door, but also can further provide a larger and clearer effective field of view through the blind spot window of the door, thereby improving driving safety.

[0083] Since the vehicle door of the embodiment of the present invention includes the above-mentioned blind spot window assembly, the vehicle door has all the advantages and beneficial effects of the above-mentioned embodiments, which will not be described in detail here.

[0084] like Figures 3 to 5 As shown, an embodiment of the third aspect of the present invention provides a vehicle, including a cab body, and two doors as in any of the above embodiments, the door bodies 4 of the two doors are movably connected to the cab body, and the two doors are relatively arranged along the left and right directions of the vehicle.

[0085] Since the vehicle door described above is included, the vehicle of the embodiment of the present invention has all the advantages and beneficial effects of the above embodiments, which will not be described in detail here.

[0086] like Figures 3 to 6 As shown, an embodiment of the fourth aspect of the present invention provides a method for optimizing the field of view of a blind window, which is used to optimize the field of view of a blind window assembly on a vehicle door. The method for optimizing the field of view of a blind window specifically comprises the following steps:

[0087] Step S100, obtaining the door profile, the glass body operating profile and the preset eye point;

[0088] Among them, the door profile refers to the contour shape of the outside and inside of the door, including at least the shape design of the door outer panel and the door inner panel. The glass body running profile refers to the trajectory surface followed by the window glass body during the lifting process, which is related to the layout 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 based on the position of the eyes of a driver of standard height sitting in the driver's seat with a standard sitting posture when looking at the blind window. The field of view analysis is carried out 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 installation 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 inner and outer directions of the door, and the 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 running surface of the glass body to ensure the operating 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 will affect the layout of the interior panels and other internal components and affect the driving space.

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

[0092] The outer shielding frame and the inner shielding frame are arranged on the inner and outer sides of the glass body, and the inner boundary of the outer shielding frame Y and the outer boundary of the inner shielding frame Y are further selected through the running profile of the glass body to avoid interference with the running glass body and ensure the maximum field of view. The boundary position needs to maintain a certain distance from the running track surface of the glass body to ensure sufficient space.

[0093] Step S400, presetting the upper boundary of the interior trim 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 ergonomic requirements, and it is necessary to ensure that the interior panel does not block the driver's field of vision from the preset eye point.

[0095] Step S500, determining 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 interior trim panel, the connection structure between the inner window assembly and the door, and the Y-direction installation range of the lifter mounting plate;

[0096] Among them, by considering the preset upper boundary of the interior panel, the connection structure between the inner window assembly and the interior panel, and the layout position of the lifter mounting plate, the inner and outer limit positions of the upper boundary of the inner window assembly are determined, and then the upper boundary of the inner window assembly is selected from the position range between 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. This can reduce the obstruction of the inner window assembly's field of view by the interior panel, thereby optimizing and increasing the field of view.

[0097] Step S600, determining the lower boundary of the inner window assembly according to the door profile, the Y-direction installation range of the lifter mounting plate, and the connection structure between the inner window assembly and the interior trim panel, and making a viewing surface from a preset eye point to the lower boundary of the inner window assembly to form a first bottom plate profile and a second bottom plate profile;

[0098] Among them, the Y-direction installation range of the lifter mounting plate is a range in which the lifter mounting plate can be installed. The inner door panel has a draft angle. The closer the position of the lifter mounting plate is to the outside of the vehicle, the higher the starting point of the lower boundary of the inner window assembly is, thereby directly reducing the field of view area. Therefore, based on the principle that the lifter mounting plate is as close to the inside of the vehicle as possible, the installation position of the lifter mounting plate can be determined, and then the lower boundary of the inner window assembly can be determined in combination with the door profile and the connection structure between the inner window assembly and the interior trim panel. The field of view surface is made from the preset eye point to the lower boundary of the inner window assembly. The formed first bottom plate profile and second bottom plate profile can greatly expand the field of view below the blind window.

[0099] Step S700, according to the door profile, the connection structure between the outer shielding frame and the door outer panel, and the Y-direction installation range of the lifter mounting plate, determine the front boundary and the rear boundary of the outer shielding frame, make a visual field from a preset eye point to the front boundary of the outer shielding frame to form a first front panel profile and a second front panel profile, make a visual field from the preset eye point to the rear boundary of the outer shielding frame to form a first rear panel profile and a second rear panel profile;

[0100] Among them, the installation position of the lifter mounting plate is selected from the installation range of the lifter mounting plate in the Y direction, and then the outer shielding frame and the outer door panel are combined to ensure that the outer shielding frame is firmly connected to the outer door panel, so as to determine the front boundary of the outer shielding frame, and the visual field is formed from the preset eye point to the front boundary of the outer shielding frame to form the first front panel profile and the second front panel profile, so that the first front panel and the second front panel both extend along the visual line direction of the preset eye point, and expand the visual line of the front side of the blind window. Similarly, the installation position of the lifter mounting plate is selected from the installation range of the lifter mounting plate in the Y direction, and then the outer shielding frame and the outer door panel are combined to ensure that the outer shielding frame and the outer door panel are firmly connected, so as to determine the rear boundary of the outer shielding frame, and form the first rear panel profile and the second rear panel profile, so that the first rear panel and the second rear panel both extend along the visual line direction of the preset eye point, and expand the visual line of the rear side of the blind window.

[0101] Step S800, based on multiple lifter mounting plate Y-direction mounting positions selected within the lifter mounting plate Y-direction mounting range, multiple inner window assembly upper boundary positions selected within the range from the outer limit position of the inner window assembly upper boundary to the inner limit position of the inner window assembly upper boundary, and the inner window assembly lower boundary, outer shielding frame front boundary and outer shielding frame rear boundary selected at different lifter mounting plate Y-direction mounting positions, obtain multiple field of view volume combinations formed within the range enclosed 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 of the preset eye point.

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

[0103] Through the above steps, this embodiment can ensure that the arrangement of the blind spot window on the door not only reduces the blind spot, but also fully considers the compatibility of the door structure, interior layout and glass lifting assembly, optimizes and expands the upper and lower front and rear field of view of the blind spot window assembly, reduces the occupation of the door structure, interior layout and glass lifting assembly on the field of view of the blind spot window assembly, improves the effective field of view of the driver, and solves the problem in the related art that the internal structure of the door easily reduces the effective field of view area of ​​the blind spot window.

[0104] Optionally, by using 3D drawing software or visual field analysis software, the line of sight from a preset eye point can be simulated and interleaved with the shapes of the door, blind window assembly, interior trim panel and glass lift assembly to form different visual fields. The volume of these visual fields is calculated in 3D space to find the layout combination that can provide the maximum visual field volume, including the circumferential boundary position and visual field angle of the outer shielding frame and the inner shielding frame, and multiple iterations can be performed until the optimal solution is found.

[0105] In some embodiments, after determining the outer limit position of the upper boundary of the inner window component and the inner limit position of the upper boundary of the inner window component in step S500, the blind window field of view optimization method further includes:

[0106] Make a first visual plane from the preset eye point to the outer limit position of the upper boundary of the inner window assembly, and make a second visual plane from the preset eye point to the inner limit position of the upper boundary of the inner window assembly, and check whether the boundary of the interior trim panel blocks the first visual plane and the second visual plane;

[0107] If the upper boundary of the interior trim panel is above the first visual field, the upper boundary of the interior trim panel does not block the visual field of the inner 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 panel is between the first and second visual planes, the upper boundary of the interior panel blocks the first visual plane, indicating that the interior panel blocks the driver's line of sight and affects the visual effect of the blind spot window. At this time, it is necessary to re-make the visual plane from the preset eye point to the upper boundary of the interior panel to form a new first visual plane; or, adjust the upper boundary of the interior panel upward until the adjusted upper boundary of the interior panel is above the first visual plane. This new first visual plane will accurately reflect the actual impact of the upper boundary of the interior panel on the visual field. Based on this new first visual plane, the degree of obstruction of the interior panel is evaluated and corresponding adjustments are made, such as lowering the height of the interior panel or modifying its shape to avoid or minimize visual obstruction.

[0109] Through the above steps, the layout of the interior panels can be systematically checked and optimized to reduce unnecessary restrictions on the field of view of the blind spot windows, thereby improving the driving safety of the vehicle. Through verification, precise adjustment and optimization can be facilitated.

[0110] Among them, if the upper edge of the interior trim panel is below the second field of view, then the field of view from the preset eye point to the upper edge of the interior trim panel is the upper field of view. The Y-axis position of the inner window assembly has no effect on the upper field of view, but this situation will block the field of view of the blind window too much and should be avoided.

[0111] In some embodiments, step S200, determining the Y-direction installation range of the lifter mounting plate according to the vehicle door profile and the glass body running profile, includes:

[0112] According to the door profile, determine the door outer panel profile, door inner panel profile and door glass blocks;

[0113] Among them, door glass segmentation refers to dividing the door glass into different areas according to design requirements, usually to meet different functional requirements.

[0114] Determine the position of the door outer handle according to the door outer panel profile, door inner panel profile and door glass blocks;

[0115] Among them, the specific position of the door handle on the door outer panel is determined based on the ergonomic layout and styling input. This step requires ensuring that the handle position is convenient for operation and does not interfere with the window glass during the lifting process.

[0116] Adjust the operating surface of the glass body according to the position of the door handle outside;

[0117] Among them, if the distance between the position of the door handle outside and the initially designed glass body running profile is too small, it may affect the smoothness and safety of the glass body lifting and lowering. Therefore, it is necessary to adjust the running trajectory of the glass body to ensure that the minimum distance from the door handle outside is equal to or greater than 10 mm. At the same time, the maximum distance between the glass body running profile after adjustment and the glass body running profile input by the modeling should be less than or equal to 1 mm to maintain the consistency and aesthetics of the design. Adjust the glass body running profile according to the position of the door handle outside to ensure that there is enough gap between the glass body and the door handle outside, which can further optimize the glass body running profile, avoid unnecessary structural obstruction, and create conditions for increasing the field of view of the blind window. By fine-tuning the glass body running surface, the impact on the field of view of the blind window can be minimized while maintaining smooth window operation.

[0118] According to the adjusted running surface of the glass body and the door glass blocks, determine the supporting structure and supporting position of the door to the glass body;

[0119] Among them, the supporting structure of the door to the glass body refers to the glass rail, window slide and other structures. The position of the glass lifter's rail bracket is determined according to the structure and position of the glass rail and window slide. The minimum distance between the glass lifter's rail bracket and the window slide is greater than or equal to 20 mm. The supporting structure and supporting position directly affect the installation position of the glass lifter, and then affect the running surface of the glass body. By optimizing the supporting structure and supporting position, it can be ensured that the glass body will not be restricted by the internal structure during the lifting process, providing a larger field of view for blind window filling.

[0120] Determine the position of the glass lifter according to the supporting structure and position of the door to the glass body;

[0121] Among them, by reasonably arranging the glass lifter inside the car door, it can be ensured that the glass body avoids interference with the internal structure during the lifting process. At the same time, the optimized layout of the glass lifter can also reduce the impact on the field of view of the inner window assembly, thereby maximizing the field of view.

[0122] According to the door inner panel profile and the position of the glass lifter, determine the installation range of the lifter mounting plate in the Y direction, where the position of the lifter mounting plate corresponding to the position of the glass lifter closest to the door outer panel is the Y-outward limit position of the lifter mounting plate, the position of the lifter mounting plate corresponding to the position farthest from the door outer panel that the door inner panel can provide is the Y-inward limit position of the lifter mounting plate, and the position closest to the interior of the vehicle is the limit assembly position that the door inner panel can provide after considering the sealing, structural rigidity, and stamping process. The placement of the lifter mounting plate can also be combined with the arrangement of other parts inside the door, and the material can also be made of plastic mold parts as much as possible, so as to make the arrangement of internal parts more flexible. The final position of the lifter mounting plate can be selected as close to the interior of the vehicle as possible.

[0123] The Y-direction installation range of the lifter mounting plate determines the available space of the inner window assembly, which directly affects its field of view. Selecting the position of the lifter mounting plate at the limit position closest to the inner door panel, that is, the Y-direction inner limit position of the lifter mounting plate, can avoid its obstruction of the field of view to the greatest extent 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 slide, mechanical interference can be avoided and the smooth lifting and lowering of the glass body can be ensured.

[0124] With such arrangement, this embodiment optimizes the internal structure of the door, adjusts the glass lifting trajectory and determines the position of the lifter mounting plate, thereby ensuring the functionality and safety of the door while minimizing the obstruction of the driver's line of sight by the internal structure, allowing the driver to obtain a wider field of vision, reducing blind spots and improving driving safety.

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

[0126] Keeping the inner end of the outer shielding frame at a first preset distance from the running profile of the glass body;

[0127] Keeping the outer end of the inner shielding frame at a second preset distance from the running profile of the glass body;

[0128] Among them, the range of the first preset distance and the second preset distance is 5 mm-10 mm. For example, the first preset distance and the second preset distance can be selected as 7 mm, which can not only provide sufficient operating space for both sides of the glass body, but also avoid the situation where the distance between the outer shielding frame and the inner shielding frame is too large, causing the inner components of the door to enter the cavity between the outer shielding frame and the inner shielding frame through the gap between the inner shielding frame and the outer shielding frame, thereby reducing the impact of the inner 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, includes:

[0130] Determine the lower boundary of the window and the positions of the inner and outer switches of the door according to the door profile;

[0131] Based on the principles that the inside and outside door switches are located as close to the upper edge of the interior panel as possible, the size of the inside and outside door switches is as small as possible, and the Y-direction dimension of the interior panel is as thin as possible, the upper edge of the interior panel is preset according to the human-machine field of vision requirements of the lower edge of the window and the preset eye point.

[0132] Among them, the lower boundary of the window refers to the lowest boundary of the window window, and the inside and outside switches of the door refer to the door handle switch and the inner opening handle. The position of the door handle switch and the position of the outer door handle can be the same position, or the door handle switch and the outer door handle can be transmission-connected, and a certain distance can be set between the two. In this embodiment, the inside and outside switches of the door are arranged according to the position of the upper boundary of the interior trim panel, and the Z-direction height dimension of the inside and outside switches of the door is reduced as much as possible, and the arrangement position is as close to the upper boundary of the interior trim panel as possible. The pull wire of the inner opening handle is arranged at the rear of the inner opening handle, and the Z-direction dimension of the connection structure between the inner opening handle and the interior trim panel is as small as possible, and the total height of the inner opening handle is not increased. For doors that apply blind windows, the inner opening handle can be arranged on the upper surface of the interior trim panel, or the door handle and the inner opening handle can be designed as one component, thereby reducing the Z-direction dimension of this part of the structure of the inside and outside switches of the door. According to the verification of the human-machine operation space and the arrangement of the internal components of the door, the interior trim panel and its Y-direction dimension are reduced as much as possible. The upper limit of the interior panel is preset according to the lower limit of the window determined by the shape and the human-machine field of vision. That is, the upper limit of the interior panel is determined by the line of sight path starting from the preset eye point. The upper limit of the interior panel can enable the driver to obtain a clear and wide field of vision when observing from the preset eye point, reduce the excessive influence of the upper limit of the interior panel or the switches inside and outside the door on the upper limit of the blind window, and improve the field of vision of the blind window.

[0133] In some embodiments, step S500, according to the preset upper boundary of the interior panel, the connection structure between the inner window assembly and the interior panel, and the Y-direction installation range of the lifter mounting plate, 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, including:

[0134] The inward limit position Y of the connection structure between the lifter mounting plate and the inner window assembly is determined based on the upper boundary of the door interior and the connection structure between the inner window assembly and the interior panel; wherein the inward limit position Y of the connection structure between the lifter mounting plate and the inner window assembly refers to the limit position of the connection structure between the lifter mounting plate and the inner window assembly in the Y direction close to the interior of the vehicle, and the inward limit position Y of the connection structure between the lifter mounting plate and the inner window assembly needs to take into account the shape of the interior panel and the connection structure between the inner window assembly and the interior panel, reduce the restrictions on the installation position of the inner window assembly by the door interior or other door components at this position, and also ensure that there is sufficient installation space for the lifter mounting plate and the inner shielding frame of the inner window assembly.

[0135] According to the position of the inner window assembly and the minimum size of the connection structure between the inner window assembly and the lifter mounting plate, determine the outer limit position Y of the connection structure between the lifter mounting plate and the inner window assembly; wherein, the outer limit position Y of the connection structure between the lifter mounting plate and the inner window assembly refers to the limit position of the connection structure between the lifter mounting plate and the inner window assembly in the Y direction close to the outside of the vehicle, and the outer limit position Y of the connection structure between the lifter mounting plate and the inner window assembly needs to consider the profile of the interior trim panel, as well as the connection position between the inner shielding frame of the inner window assembly and the glass profile, so as to reduce the positional interference between the inner window assembly, the glass profile and the lifter mounting plate. The outer limit position Y of the connection structure between the lifter mounting plate and the inner window assembly is mainly constrained by the maximum size of the connection structure between the inner window assembly and the lifter mounting plate, ensuring that even in the outermost position, the lifter mounting plate can firmly support the inner window assembly, and at the same time, there is no positional interference with the glass profile, so as to maintain the integrity of the internal structure of the vehicle door.

[0136] Determine 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 based on the inward limit position of the connection structure Y between the lifter mounting plate and the inner window assembly, the outward limit position of the connection structure Y between the lifter mounting plate and the inner window assembly, the profile of the interior panel and the dimensions of the connection structure between the inner window assembly and the interior panel.

[0137] With such an arrangement, the size of the connection structure between the inner window assembly and the interior trim panel, and the position of the connection structure between the inner window assembly and the lifter mounting plate are used to reduce the installation and movement range of the upper portion of the inner window assembly, reduce the position interference between the inner window assembly and the interior trim panel or other internal structures of the door when the inner window assembly is raised to the highest point, and ensure a better field of view of the preset eye point at the upper portion of the blind window.

[0138] In some embodiments, step S600, determining the lower boundary of the inner window assembly according to the door profile, the Y-direction installation range of the lifter mounting plate, and the connection structure between the inner window assembly and the interior trim panel, includes:

[0139] According to the connection structure between the interior panel and the door inner panel and the door inner panel profile, determine the installation position of the lifter mounting plate and the door inner panel. This step is based on the door profile and the door inner panel profile, taking into account the internal structure layout of the door, especially the connection structure between the interior panel and the door inner panel, to determine the specific installation position of the lifter mounting plate inside the door. The position of the lifter mounting plate must ensure that it can be firmly installed on the door inner panel without interfering with other door components, such as the glass lifter, interior panel, etc., reducing the minimum height restriction on the inner window assembly inside the door.

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

[0141] The lower boundary of the inner window assembly is determined according to the starting position of the lower boundary of the inner window assembly, the installation dimensions of the lifter mounting plate, and the connection structure between the inner window assembly and the interior trim panel.

[0142] Among them, the position of the installation surface of the lifter mounting plate and the door inner panel is determined according to the connection structure of the interior panel and the door inner panel and the draft angle of the door inner panel. The inner limit position of the lifter mounting plate Y is a range, that is, the position closest to the outside of the vehicle is the installation limit position of the glass lifter guide rail, and the position closest to the inside of the vehicle is the limit assembly position that the door inner panel can provide after considering sealing, structural rigidity, sealing, and stamping process. Due to the draft angle of the door inner panel, the closer the position of the lifter mounting plate is to the outside of the vehicle, the higher the starting point of the lower boundary of the inner window assembly is, which will directly reduce the field of view area. Therefore, the position of the lifter mounting plate should be selected at the limit position closest to the inside of the vehicle. According to the starting position of the lower boundary of the inner window assembly, the installation size of the lifter mounting plate, the connection structure of the inner window assembly and the interior panel, for example, the size of the quick-release structure fixing part, the lower boundary of the inner window assembly is determined, and the field of view surface is made 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 where the lower boundary of the inner window assembly is located, so that the lower part of the blind window has a larger field of view.

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

[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, as well as 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 7 mm. This can ensure sufficient avoidance space between the two sides of the glass body and the outer shielding frame and the inner shielding frame, reduce position interference, and avoid excessive spacing between the inner shielding frame and the outer shielding frame, which would cause the internal components of the door to be exposed.

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

[0146] Among them, the installation parameters of the glass lifter may include but are not limited to the 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 cables 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 invention are only examples for clearly illustrating the present invention, and are not limitations on the implementation methods of the present invention. For ordinary technicians in the field, various obvious changes, readjustments, and substitutions can be made without departing from the scope of protection of the present invention. It is not necessary and impossible to list all the implementation methods here.
