Description

Technical Field

[0001] This application relates to the technical field of automotive glass, and more particularly to a heated side window glass and a vehicle. Background Technology

[0002] While driving, drivers need to frequently check the surrounding traffic conditions using the left and right rearview mirrors to avoid accidents.

[0003] If the side windows fog up or are covered with rain, snow, or frost, it will seriously affect the driver's ability to see the left and right rearview mirrors, posing a safety hazard. To solve these problems, related technologies mention adding longitudinally arranged heating wires inside the side windows to heat the glass and thus defrost and defog it.

[0004] However, because the heating wires are arranged longitudinally inside the side window glass, they can easily cause eye discomfort to the driver when the vehicle is in motion. Summary of the Invention

[0005] This application provides a heated side window glass and a vehicle to solve the problem that the heating wires are arranged longitudinally inside the side window glass, which can easily cause eye discomfort to the driver when the vehicle is in motion.

[0006] This application provides a heatable side window glass with an upper edge, a lower edge, a front edge and a rear edge, including an outer glass plate, a thermoplastic intermediate layer and an inner glass plate stacked in sequence. The thermoplastic intermediate layer is provided with a first busbar, a second busbar and at least one heating wire. The first busbar and the second busbar are both located below the water tangent in the outer glass plate and are close to the rear edge and the front edge, respectively.

[0007] The heating wire includes an input section, a paving section, and an output section connected in sequence. The input section is electrically connected to the first busbar and is arranged along the rear edge. The paving section meanders around the thermoplastic intermediate layer. The outer and inner glass plates have float glass stripes extending from the front edge to the rear edge. The line connecting the beginning and end of the float glass stripes forms a stripe line. The arrangement direction of some paving sections is consistent with the stripe line. The output section is electrically connected to the second busbar and is arranged along the front edge.

[0008] By adopting the above technical solution, the first and second busbars are hidden by placing them below the water tangent in the outer glass panel, thereby improving the aesthetics of the side window glass.

[0009] By dividing the heating wire into an input section, a paving section, and an output section, with the paving section meandering around the thermoplastic intermediate layer, the side window glass is heated, thereby achieving defrosting and defogging of the side window glass.

[0010] The paving direction of some sections is consistent with the stripe lines, so that the heating wires are almost identical to the stripe lines in the side window glass. This gives the driver a better visual experience when looking at the rearview mirror through the side window glass, and is less likely to cause visual obstruction or eye discomfort.

[0011] In one possible implementation, the present application provides a heatable side window glass, the paving section including several extension sections and several connecting sections, each extension section is arranged sequentially at intervals from the upper edge to the lower edge, the beginning and end of adjacent extension sections are connected by connecting sections, and the extension sections are arranged in the same direction as the stripe lines.

[0012] By adopting the above technical solution, several extension sections and several connecting sections are connected to form a meandering paving section, which allows the paving section to fully heat the side window glass located inside the vehicle window, thereby ensuring the defrosting and defogging effect of the entire side window glass.

[0013] The extension section is much longer than the connecting section. The extension section is aligned with the stripe lines, and the connecting section is close to the front and rear edges, minimizing the visual obstruction caused to the driver by the extension section and the connecting section.

[0014] In one possible implementation, this application provides a heatable side window glass with equal spacing between adjacent extension segments.

[0015] By adopting the above technical solution and making the spacing between adjacent extension sections the same, not only is the aesthetic appearance of the paving section laid out inside the side window glass improved, but it is also less likely to cause visual fatigue to the driver.

[0016] In one possible implementation, the present application provides a heatable side window glass in which the distance between the first busbar and the second busbar and the lower edge is greater than 1 mm.

[0017] The spacing between the first and second busbars and the lower edge is limited to be greater than 1mm, which avoids the first and second busbars being too close to the lower edge, thus increasing the installation difficulty.

[0018] In one possible implementation, the present application provides a heatable side window glass in which the distance between the first busbar and the second busbar and the water tangent is greater than 1 mm.

[0019] By adopting the above technical solution, the distance between the first and second busbars and the water tangent is limited to more than 1 mm, thus avoiding the first and second busbars being too close to the water tangent, which would increase the difficulty of installation.

[0020] In one possible implementation, the present application provides a heatable side window glass in which the longitudinal height difference between the first busbar and the second busbar is greater than or equal to 0 mm.

[0021] By adopting the above technical solution, there is a longitudinal height difference between the first busbar and the second busbar, so that the positions of the first busbar and the second busbar can be adjusted according to the arrangement of the upper edge of the side window glass. The arrangement of the input section and the output section of the heating wire can be defined by the first busbar and the second busbar, thereby facilitating the installation of the heating wire inside the side window glass.

[0022] In one possible implementation, this application provides a heatable side window glass with a spacing of 10mm-15mm between adjacent extension segments.

[0023] By adopting the above technical solution and limiting the spacing between adjacent extension sections, not only is the heating effect of the heating wire on the side window glass guaranteed, but the dense arrangement of the heating wire is also avoided as much as possible, thus avoiding visual obstruction to the driver.

[0024] In one possible implementation, the present application provides a heatable side window glass with a distance between the input segment and the rear edge and between the output segment and the front edge of 2mm-5mm.

[0025] By adopting the above technical solution, the positions of the input segment and the output segment relative to the rear edge and the front edge are defined, so that the input segment and the output segment are hidden inside the door as much as possible, thereby improving the aesthetics of the side window glass.

[0026] In one possible implementation, the present application provides a heatable side window glass, wherein the connecting segment is arranged along the front edge or the rear edge and is located between the input segment and the output segment, and the distance between the connecting segment and the front edge and the rear edge is between 4mm and 7mm.

[0027] By adopting the above technical solution, the position of the connecting segment relative to the rear edge and the front edge is defined, so that the connecting segment is hidden inside the door as much as possible, thereby improving the aesthetics of the side window glass.

[0028] This application also provides a vehicle, including a vehicle body and a heated side window glass of any of the above-described technical solutions mounted on the vehicle body.

[0029] This application provides a heatable side window glass and a vehicle. The heatable side window glass includes an outer glass panel, a thermoplastic intermediate layer, and an inner glass panel stacked sequentially. The thermoplastic intermediate layer is provided with a first busbar, a second busbar, and at least one heating wire. By placing the first and second busbars below the water tangent in the outer glass panel, their positions are hidden, improving the aesthetics of the side window glass. The heating wire includes an input section, a paving section, and an output section. The outer and inner glass panels have float glass stripes extending from the front edge to the rear edge. The line connecting the beginning and end of the float glass stripes forms a stripe line. By aligning the layout direction of a portion of the paving section with the stripe line, the driver has a better visual experience when observing the rearview mirror through the side window glass, and it is less likely to cause visual obstruction and eye discomfort to the driver.

These drawings and descriptions are not intended to limit the scope of the concept in any way, but rather to illustrate the concept of this application to those skilled in the art through reference to particular embodiments. Detailed Implementation

[0054] To make the objectives, technical solutions, and advantages of this application clearer, the technical solutions of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0055] The terms "first," "second," "third," "fourth," etc. (if present) in the specification, claims, and accompanying drawings of this application are used to distinguish similar objects and are not necessarily used to describe a particular order or sequence. It should be understood that such data can be interchanged where appropriate so that embodiments of the application described herein can be implemented, for example, in orders other than those illustrated or described herein. In embodiments of this application, the words "exemplary" or "for example" are used to indicate examples, illustrations, or descriptions. Any embodiment or design described as "exemplary" or "for example" in this application should not be construed as being more preferred or advantageous than other embodiments or designs. Specifically, the use of the words "exemplary" or "for example" is intended to present the relevant concepts in a concrete manner.

[0056] As mentioned in the background technology: while driving, drivers need to frequently check the surrounding traffic conditions through the left and right rearview mirrors to avoid accidents.

[0057] If the side windows fog up or are covered with rain, snow, or frost, it will seriously affect the driver's ability to see the left and right rearview mirrors, posing a safety hazard. To solve these problems, related technologies mention adding longitudinally arranged heating wires inside the side windows to heat the glass and thus defrost and defog it.

[0058] For example, CN111775669B discloses a heated side window glass for automobiles, having an upper edge, a lower edge, a front edge, and a rear edge, including an outer glass panel, a thermoplastic interlayer, and an inner glass panel. At least three metal wires are embedded in the thermoplastic interlayer. Each metal wire has a first extension segment, a second extension segment, and at least one bent segment. The bottom end of the first extension segment is electrically connected to a first busbar and extends towards the upper edge. The bottom end of the second extension segment is electrically connected to a second busbar and extends towards the upper edge. The second extension segment insulatedly passes through the first busbar. The top end of the first extension segment is electrically connected to the top end of the second extension segment through at least one bent segment.

[0059] That is, the heating wire in the above technical solution is arranged in a longitudinal direction.

[0060] Because the heating wires are arranged longitudinally inside the side window glass, they can easily cause eye discomfort to the driver when the vehicle is in motion.

[0061] To address the aforementioned technical problems, this application provides a heatable side window glass and a vehicle. The heatable side window glass includes an outer glass panel, a thermoplastic intermediate layer, and an inner glass panel stacked sequentially. The thermoplastic intermediate layer contains a first busbar, a second busbar, and at least one heating wire. By positioning the first and second busbars below the water tangent in the outer glass panel, their positions are concealed, improving the aesthetics of the side window glass. The heating wire includes an input section, a paving section, and an output section. The outer and inner glass panels have float glass stripes extending from the front edge to the rear edge. The lines connecting the beginning and end of the float glass stripes form stripe lines. By aligning the paving section's layout direction with the stripe lines, the driver has a better visual experience when observing the rearview mirror through the side window glass, reducing visual obstruction and eye discomfort.

[0062] The technical solution of this application and how the technical solution of this application solves the above-mentioned technical problems are described in detail below with specific embodiments. These specific embodiments can be combined with each other, and the same or similar concepts or processes may not be described again in some embodiments. The embodiments of this application will now be described with reference to the accompanying drawings.

[0063] refer to Figures 1-3This application discloses a heatable side window glass with an upper edge 10, a lower edge 20, a front edge 30, and a rear edge 40. It includes an outer glass plate 100, a thermoplastic intermediate layer 200, and an inner glass plate 300 stacked in sequence. The thermoplastic intermediate layer 200 is provided with a first busbar 400, a second busbar 500, and at least one heating wire 600. The first busbar 400 and the second busbar 500 are both located below the water tangent 700 in the outer glass plate 100 and are close to the rear edge 40 and the front edge 30, respectively.

[0064] The heating wire 600 includes an input section 610, a paving section 620, and an output section 630 connected in sequence. The input section 610 is electrically connected to the first busbar 400 and is arranged along the rear edge 40. The paving section 620 meanders around the thermoplastic intermediate layer 200. The outer glass plate 100 and the inner glass plate 300 have float glass stripes 800 extending from the front edge 30 to the rear edge 40. The line connecting the beginning and end of the float glass stripes 800 forms a stripe line 810. The arrangement direction of some paving sections 620 is consistent with the stripe line 810. The output section 630 is electrically connected to the second busbar 500 and is arranged along the front edge 30.

[0065] The upper edge 10 refers to the edge of the side window glass that is located on the upper side or near the roof in the installation space structure.

[0066] The lower edge 20 refers to the edge of the side window glass that is located on the side below the space or close to the ground.

[0067] The front edge 30 refers to the edge of the side window glass that faces the front of the vehicle or points forward along the direction of the vehicle's movement.

[0068] The rear edge 40 refers to the edge of the side window glass located on the rear side of the vehicle or pointing towards the rear along the front-rear direction of the vehicle.

[0069] Both the outer glass panel 100 and the inner glass panel 300 are made of float glass. Float glass ripples 800 are a forming defect in float glass; their location is not fixed and shifts from one place to another as the glass sheet is pulled. Also known as ripples, ripples, or water lines, they refer to wavy stripes on the glass surface.

[0070] The specific direction of the float glass striations 800 can be determined by a float glass striation testing device.

[0071] After the side window glass is installed on the car door window, a waterstop strip needs to be installed between the car door and the side window glass. The waterstop strip is used to seal the side window glass and the car door. The waterstop line 700 refers to the line where the side window glass is flush with the waterstop strip. The side window glass can be raised and lowered on the car door, and the side window glass located below the waterstop line 700 is always hidden inside the car door.

[0072] For example, the heating wire 600 can be set as one or multiple wires, and there is no limitation on this. The spreading section 620 of the multiple heating wires 600 is arranged sequentially from the upper edge 10 to the lower edge 20.

[0073] By adopting the above technical solution, the first busbar 400 and the second busbar 500 are hidden by placing them below the water tangent 700 in the outer glass panel 100, thereby improving the aesthetics of the side window glass.

[0074] By dividing the heating wire 600 into an input section 610, a paving section 620, and an output section 630, the paving section 620 meanders around the thermoplastic intermediate layer 200 to heat the side window glass, thereby achieving defrosting and defogging of the side window glass.

[0075] The laying direction of some paving sections 620 is consistent with the stripe line 810, so that the heating wire 600 is almost consistent with the stripe line 810 in the side window glass, so that the driver has a better visual experience when looking at the rearview mirror through the side window glass, and is less likely to cause visual obstruction and eye discomfort to the driver.

[0076] In some embodiments, reference Figure 1 The paving section 620 includes several extension sections 621 and several connecting sections 622. Each extension section 621 is arranged sequentially at intervals from the upper edge 10 to the lower edge 20. The beginning and end of adjacent extension sections 621 are connected by connecting sections 622. The extension sections 621 are laid in the same direction as the stripe lines 810.

[0077] For example, the extension segment 621 extends from the rear edge 40 to the front edge 30, and the connecting segment 622 is located near the front edge 30 and the rear edge 40 of the side window glass, such that the length of the extension segment 621 is much greater than the length of the connecting segment 622.

[0078] By adopting the above technical solution, several extension sections 621 and several connecting sections 622 are connected to form a meandering paving section 620, which allows the paving section 620 to fully heat the side window glass located inside the vehicle window, thereby ensuring the defrosting and defogging effect of the entire side window glass.

[0079] The length of the extension segment 621 is much greater than the length of the connecting segment 622. The extension segment 621 is aligned with the direction of the stripe line 810. Moreover, the connecting segment 622 is close to the front edge 30 and the rear edge 40, which minimizes the visual obstruction caused to the driver by the extension segment 621 and the connecting segment 622.

[0080] In some embodiments, reference Figure 1 The spacing between adjacent extension segments 621 is the same.

[0081] By adopting the above technical solution and making the spacing between adjacent extension sections 621 the same, not only is the aesthetic appearance of the paving section 620 arranged inside the side window glass improved, but it is also less likely to cause visual fatigue to the driver.

[0082] In some embodiments, the distance between the first busbar 400 and the second busbar 500 and the lower edge 20 is greater than 1 mm.

[0083] By adopting the above technical solution, the distance between the first busbar 400 and the second busbar 500 and the lower edge 20 is limited to be greater than 1mm, thus avoiding the first busbar 400 and the second busbar 500 being too close to the lower edge 20, which would increase the difficulty of installation.

[0084] In some embodiments, the distance between the first busbar 400 and the second busbar 500 and the water tangent 700 is greater than 1 mm.

[0085] By adopting the above technical solution, the distance between the first busbar 400 and the second busbar 500 and the water tangent 700 is limited to be greater than 1mm, which avoids the first busbar 400 and the second busbar 500 being too close to the water tangent 700, thereby increasing the installation difficulty.

[0086] In some embodiments, the longitudinal height difference between the first busbar 400 and the second busbar 500 is greater than or equal to 0 mm.

[0087] By adopting the above technical solution, there is a longitudinal height difference between the first busbar 400 and the second busbar 500, so that the positions of the first busbar 400 and the second busbar 500 can be adjusted according to the arrangement of the upper edge 10 of the side window glass. The arrangement of the input section 610 and the output section 630 in the heating wire 600 can be defined by the first busbar 400 and the second busbar 500, thereby facilitating the arrangement of the heating wire 600 inside the side window glass.

[0088] In some embodiments, the spacing between adjacent extensions 621 is between 10 mm and 15 mm.

[0089] By adopting the above technical solution, the spacing between adjacent extension sections 621 is limited, which not only ensures the heating effect of the heating wire 600 on the side window glass, but also avoids the heating wire 600 being too densely arranged, thus avoiding visual obstruction to the driver.

[0090] In some embodiments, the spacing between the input segment 610 and the rear edge 40 and between the output segment 630 and the front edge 30 is between 2 mm and 5 mm.

[0091] The front edge 30 and the rear edge 40 are hidden inside the door. After the side window is lowered, the front edge 30 and the rear edge 40 of the side window can be completely hidden inside the door, or partially hidden inside the door and partially exposed to the outside.

[0092] By adopting the above technical solution, the positions of the input segment 610 and the output segment 630 relative to the rear edge 40 and the front edge 30 are defined, so that the input segment 610 and the output segment 630 are hidden inside the door as much as possible, thereby improving the aesthetics of the side window glass.

[0093] In some embodiments, reference Figure 1 The connecting segment 622 is arranged along the front edge 30 or the rear edge 40 and is located between the input segment 610 and the output segment 630. The distance between the connecting segment 622 and the front edge 30 and the rear edge 40 is between 4mm and 7mm.

[0094] By adopting the above technical solution, the position of the connecting segment 622 relative to the rear edge 40 and the front edge 30 is defined, so that the connecting segment 622 is hidden inside the door as much as possible, thereby improving the aesthetics of the side window glass.

[0095] This application also discloses a vehicle, including a vehicle body and a heated side window glass of any of the above embodiments mounted on the vehicle body.
