[0032] The following describes in detail embodiments of the present invention, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to explain the present invention, and should not be construed as limiting the present invention.

[0033] Reference below Figure 1-Figure 5 A front windshield 100 according to an embodiment of the first aspect of the present invention will be described.

[0034] like Figure 1-Figure 3As shown, according to the front windshield 100 of the embodiment of the first aspect of the present utility model, the front windshield 100 extends upward at least to the top of the driving seat, and the front windshield 100 includes a driving field of view section 10 and a dimming section 20 connected up and down, the driving field of view section 10 is arranged in front of the driving seat, and the dimming section 20 is arranged above the driving seat, and the dimming section 20 includes: a first light-transmitting inner panel 21, a first light-transmitting outer panel 22, a first light-transmitting interlayer 23, a second light-transmitting interlayer 24 and a dimming film 25, the first light-transmitting interlayer 23 and the second light-transmitting interlayer 24 are sandwiched between the first light-transmitting inner panel 21 and the first light-transmitting outer panel 22, the dimming film 25 is sandwiched between the first light-transmitting interlayer 23 and the second light-transmitting interlayer 24, and the transmittance of the dimming film 25 is adjustable.

[0035] Among them, the front windshield 100 can extend upward to directly above the driver's seat, or to the front area directly above the driver's seat, or to the rear area directly above the driver's seat. The driver and the people in the car obtain the field of view in front of the vehicle 1000 through the driving field of view section 10. The transmittance, angle and range of the driving field of view section 10 meet the relevant provisions of the national standard "Requirements and Measurement Methods for the Forward Field of View of Automobile Drivers". The dimming section 20 can be directly above the driver's seat or to the front area directly above the driver's seat. The driver and the people in the car can increase the field of view that can be obtained through the dimming section 20. The first light-transmitting interlayer 23 and the second light-transmitting interlayer 24 are conventional interlayers set during the production process of the conventional front windshield 100. The first light-transmitting interlayer 23 and the second light-transmitting interlayer 24 can prevent the front windshield 100 from breaking and block some heat.

[0036] It is understandable to those skilled in the art that there are many ways to adjust the transmittance of the dimming film 25. For example, the dimming film 25 can be an electro-sensitive film, and the transmittance of the dimming film 25 is adjusted by adjusting the power supply of the dimming film 25. The dimming film 25 can also be a temperature-sensitive film, and the dimming film 25 is filled with a filler whose transparency changes with temperature, and the transparency of the dimming film 25 is adjusted by adjusting the temperature of the dimming film 25.

[0037] In this embodiment, the switchable film 25 is an electro-sensitive film. When a user uses the vehicle 1000 and needs sunshade due to strong sunlight, the electrodes can be used to adjust the power supply of the switchable film 25 to reduce its transmittance, thereby reducing the light from the dimming segment 20 entering the vehicle interior and meeting the user's sunshade needs. To adjust the light intensity inside the vehicle, the electrodes can be used to adjust the power supply of the switchable film 25 to adjust its transmittance, thereby adjusting the light intensity inside the vehicle. To increase the vertical field of view, the electrodes can be used to increase the transmittance of the switchable film 25, thereby allowing the user to see a wider area through the front windshield 100. Preferably, the switchable film 25 is a PDLC film, an SPD film, an EC film, or an LC film.

[0038] During the production process, the light-adjusting film 25 is first sandwiched between the first light-transmitting interlayer 23 and the second light-transmitting interlayer 24, and then the first light-transmitting interlayer 23 and the second light-transmitting interlayer 24 are sandwiched between the first light-transmitting inner panel 21 and the first light-transmitting outer panel 22. It is understood that compared to sandwiching the light-adjusting film 25 between the first light-transmitting inner panel 21 and the first light-transmitting outer panel 22, sandwiching the light-adjusting film 25 between the first light-transmitting interlayer 23 and the second light-transmitting interlayer 24 is less difficult. Furthermore, the process for sandwiching the first light-transmitting interlayer 23 and the second light-transmitting interlayer 24 between the first light-transmitting inner panel 21 and the first light-transmitting outer panel 22 is the same as the conventional production process. This reduces the difficulty of producing the front windshield 100.

[0039] According to the front windshield 100 of the embodiment of the first aspect of the present invention, on the one hand, the transmittance of the dimming section 20 can be adjusted according to the user's needs. When the light is strong, it can meet the user's shading needs. When the user does not need shading, it can increase the user's visual range. On the other hand, it can reduce the difficulty of production.

[0040] In some embodiments of the present invention, Figure 2 and Figure 3 As shown, the driving field of view section 10 includes: a second light-transmitting inner panel 11, a second light-transmitting outer panel 12, a third light-transmitting interlayer 13, and a fourth light-transmitting interlayer 14. The third light-transmitting interlayer 13 and the fourth light-transmitting interlayer 14 are stacked and sandwiched between the second light-transmitting inner panel 11 and the second light-transmitting outer panel 12. This ensures that the light transmittance of the driving field of view section 10 meets regulatory requirements. The third light-transmitting interlayer 13 is connected to the first light-transmitting interlayer 23, the second light-transmitting interlayer 24 is connected to the fourth light-transmitting interlayer 14, the second light-transmitting inner panel 11 is connected to the first light-transmitting inner panel 21, and the second light-transmitting outer panel 12 is connected to the first light-transmitting outer panel 22. Preferably, the third light-transmitting interlayer 13 and the fourth light-transmitting interlayer 14 are PVB film or EVA film.

[0041] In some embodiments of the present invention, Figure 2 and Figure 3 As shown, the second light-transmitting inner panel 11 is integrally formed with the first light-transmitting inner panel 21. Therefore, during the production process, the second light-transmitting inner panel 11 can be assembled together with the first light-transmitting inner panel 21, thereby further reducing the production difficulty and improving the reliability of the front windshield 100.

[0042] In some embodiments of the present invention, Figure 2 and Figure 3 As shown, the second light-transmitting outer panel 12 is integrally formed with the first light-transmitting outer panel 22. Thus, during the production process, the second light-transmitting outer panel 12 can be assembled together with the first light-transmitting outer panel 22, thereby further reducing the production difficulty and improving the reliability of the front windshield 100.

[0043] In some embodiments of the present invention, Figure 2-Figure 4 As shown, the first light-transmitting interlayer 23 and the third light-transmitting interlayer 13 are integrally formed. Therefore, during the production process, the first light-transmitting interlayer 23 can be assembled together with the third light-transmitting interlayer 13, thereby further reducing the production difficulty and improving the reliability of the front windshield 100.

[0044] In some embodiments of the present invention, Figure 2 and Figure 3 As shown, the second light-transmitting interlayer 24 is integrally formed with the fourth light-transmitting interlayer 14. Therefore, during the production process, the second light-transmitting interlayer 24 can be assembled together with the fourth light-transmitting interlayer 14, thereby further reducing the production difficulty and improving the reliability of the front windshield 100.

[0045] During the assembly process, the dimming film 25 is first sandwiched between the integrally formed first light-transmitting interlayer 23 and the third light-transmitting interlayer 13 and the integrally formed second light-transmitting interlayer 24 and the fourth light-transmitting interlayer 14, and then the above-mentioned light-transmitting interlayer and light-transmitting film are sandwiched between the integrally formed second light-transmitting inner panel 11 and the first light-transmitting inner panel 21 and the integrally formed second light-transmitting outer panel 12 and the first light-transmitting outer panel 22, thereby completing the assembly of the first light-transmitting inner panel 21, the first light-transmitting outer panel 22, the second light-transmitting inner panel 11, the second light-transmitting outer panel 12, the first light-transmitting interlayer 23, the second light-transmitting interlayer 24, the third light-transmitting interlayer 13, the fourth light-transmitting interlayer 14 and the dimming film 25.

[0046] In some embodiments of the present invention, Figure 2-Figure 4As shown, the thickness of the first light-transmitting interlayer 23 is less than that of the third light-transmitting interlayer 13, and the lower end of the first light-transmitting interlayer 23 and the lower end of the dimming film 25 are both connected to the upper end of the third light-transmitting interlayer 13. Thus, a space for arranging the dimming film 25 can be defined between the first light-transmitting interlayer 23 and the second light-transmitting interlayer 24. During production, the second light-transmitting interlayer 24 and the fourth light-transmitting interlayer 14 can be made to have the same thickness. Thus, conventional production processes and molds can be used to integrally mold the second light-transmitting interlayer 24 and the fourth light-transmitting interlayer 14, further reducing production difficulty and costs.

[0047] In some embodiments of the present invention, Figure 2 As shown, the sum of the thicknesses of the first light-transmitting interlayer 23 and the dimming film 25 is equal to the thickness of the third light-transmitting interlayer 13. Thus, during production, there is no need to provide a space for accommodating the dimming film 25 on the surfaces of the integrally formed second light-transmitting interlayer 24 and fourth light-transmitting interlayer 14. Instead, only the surface structure of one side of the integrally formed first light-transmitting interlayer 23 and third light-transmitting interlayer 13 needs to be changed, thereby reducing process difficulty and production costs.

[0048] In some embodiments of the present invention, Figure 5 As shown, the lower end of the second light-transmitting interlayer 24 is connected to the upper end of the fourth light-transmitting interlayer 14, and the lower end of the dimming film 25 is connected to the upper end of the third light-transmitting interlayer 13 and the upper end of the fourth light-transmitting interlayer 14 at the same time. The thickness of the second light-transmitting interlayer 24 is less than the thickness of the fourth light-transmitting interlayer 14, and the sum of the thicknesses of the first light-transmitting interlayer 23, the second light-transmitting interlayer 24 and the dimming film 25 is equal to the sum of the thicknesses of the third light-transmitting interlayer 13 and the fourth light-transmitting interlayer 14.

[0049] Therefore, on the one hand, the thickness of the first light-transmitting interlayer 23 and the second light-transmitting interlayer 24 are both thinned to accommodate the dimming film 25. On the premise that the performance parameters of the first light-transmitting interlayer 23 and the second light-transmitting interlayer 24 meet the requirements of use, the accommodation space of the dimming film 25 can be made larger, thereby increasing the thickness of the dimming film 25. In this way, the adjustment range of the transmittance can be improved. On the other hand, during the production process, the upper end of the third light-transmitting interlayer 13 and the upper end of the fourth light-transmitting interlayer 14 are jointly used to position the dimming film 25, which can reduce the process difficulty in the production process and thus reduce the production cost.

[0050] In some embodiments of the present invention, the ratio of the surface area of the driving field of view section 10 to the surface area of the front windshield 100 is 0.55-0.60. For example, the ratio of the surface area of the driving field of view section 10 to the surface area of the front windshield 100 can be 0.55, 0.56, 0.57, 0.58, or 0.60. This allows the angle and range of light transmission through the driving field of view section 10 to meet the relevant provisions of the national standard "Requirements and Measurement Methods for Forward Vision of Automobile Drivers," allowing the driver to better observe the road conditions ahead while driving. During the product design process, the ratio of the surface area of the driving field of view section 10 to the surface area of the front windshield 100 can be adjusted to meet various product design requirements.

[0051] In some embodiments of the present invention, Figure 1-Figure 3 As shown, the inner surface of the front windshield 100 is further provided with an ink printed layer 30. The ink printed layer 30 extends along the width of the vehicle body and faces the inner and outer sides of the lower edge of the dimming film 25. It is understood that light may be reflected and refracted multiple times at the boundary between the dimming film 25 and the first and second light-transmitting interlayers 23 and 24, causing the light at the boundary to directly strike the vehicle occupants. This light at the boundary may cause discomfort to the occupants. The ink printed layer 30 shields the lower edge of the dimming film 25, thereby blocking the light at the boundary and improving the appearance of the front windshield 100.

[0052] In some embodiments of the present invention, the first light-transmitting interlayer 23 is a PVB film or an EVA film, and the second light-transmitting interlayer 24 is a PVB film or an EVA film. PVB film has high light transmittance and sound insulation, while EVA film is easy to install and has low production costs. During the product design process, the materials of the first light-transmitting interlayer 23 and the second light-transmitting interlayer 24 can be selected according to the actual use.

[0053] Reference below Figure 1-Figure 4 A vehicle 1000 according to an embodiment of the second aspect of the present invention will be described.

[0056] During use of the vehicle 1000 , the user can adjust the light transmittance above the driver's seat by adjusting the light transmittance section of the dimming section 20 according to different usage needs.

[0057] According to the vehicle 1000 of the second aspect of the present invention, by setting the front windshield 100 according to the first aspect of the present invention, the transmittance of the dimming section 20 can be adjusted according to the user's needs. When the light is strong, the user's shading needs can be met, and when the user does not need shading, the user's visual range can be increased.

[0058] In some embodiments of the present invention, Figure 1-Figure 3 As shown, a sun visor is further provided on the inside of the front windshield 100, and the sun visor is located in the dimming area. The sun visor is mounted on the front windshield 100 via a sun visor mounting base 40. By providing the sun visor, the user can adjust the shading angle of the sun visor during use to meet the user's shading needs, thereby providing the user with more shading options and further improving the user's usage needs.
