Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of automotive parts, and particularly relates to a heating structure for a movable vehicle window glass. In addition, the utility model also relates to a vehicle. Background Technique
[0002] With the improvement of customers' requirements for automotive technology configurations, some vehicle models not only require the vehicle window glass to be able to be raised, lowered, flipped open or closed to achieve ventilation or sports function effects; at the same time, the vehicle window glass is also required to have a heating and defogging function. For example, not only are electric heating components configured on the rear windshield, but also the rear windshield is required to be able to be flipped open or closed and used as a moving part. In this way, two problems need to be solved:
[0003] Taking the rear windshield as an example, the existing rear windshield heating wire is pasted on the inner side of the glass. Since the rear windshield is usually fixed, the risk of the heating wire falling off is not great. However, if the rear windshield is changed to a moving part, during the process of the glass being raised, lowered, flipped open or closed, the heating wire will rub against the inner water cut fixed at the bottom of the window frame, or be involved due to the opening and closing action of the glass, and there is a risk that the electric heating wire will be worn off by the inner water cut or fall off due to being pulled by the electric connection wire, resulting in the failure of the defogging function.
[0004] For the existing wire harness that supplies power to the electric heating wire, one end of it is fixed to the window frame, and the other end needs to move with the glass. The wire harness is directly suspended on the rear door and cannot be fixed over a long distance. When the glass is raised or lowered, the wire harness will rise and fall with the glass, resulting in the wire harness curling and hanging on other fixed parts, or the wire harness being affected by frequent bending of straightening - bending - straightening, which affects the service life of the wire harness, causing the wire harness encapsulation to crack due to fatigue, and further leading to a short circuit of the wire. Summary of the Utility Model

[0033] The present invention will be described in detail below with reference to the drawings and in combination with embodiments.
[0034] Embodiment 1
[0035] This embodiment relates to a heating structure for a mobile window glass, thereby providing an electric heating power supply solution suitable for being arranged on a mobile window glass; an exemplary structure thereof is as Figure 1 、 Figure 2 and Figure 3 shown.
[0036] Generally speaking, the heating structure of the movable vehicle window glass includes a window glass, an electric heating layer attached to the window glass, and a power supply unit. Among them, the window glass is movably arranged in the window frame, and an electrical connection part for connecting the electric heating layer is provided at one side edge of the window glass; the power supply unit is correspondingly arranged on the frame of the window frame and forms an electrical connection with the electrical connection part when the window glass is closed.
[0037] It should be noted that based on the above overall design concept, the technical solution of the present utility model can adopt a variety of different specific implementation structures, forms or configuration sequences. For example, the above window glass can be the window glass on the side door of the vehicle or the rear windshield of the vehicle. The electric heating layer can be arranged on the inner or outer surface of a single-layer window glass, or can be arranged between the two layers of a double-layer glass. For the parts required for the implementation of the overall solution but not involved in the above overall setting, reasonable and flexible designs can be made with reference to the mature setting means in the art, the actual situation during implementation, etc. The following specific implementation solutions of this embodiment are only one of the better ones among the many solutions that can be formed by the above various combinations and their variations. In actual implementation, those skilled in the art can make flexible adjustments and improvements in combination with the actual situation. Obviously, the many solutions that can be formed by the above various specific form combinations and their variations, as well as the specific implementation solutions of this embodiment, are all within the protection scope of the present utility model.
[0038] Specifically, in this embodiment, as Figure 2 , Figure 3 and in combination with Figure 4 shown, the window glass includes a first layer of glass 1 and a second layer of glass 2 arranged in a stacked manner, and the electric heating layer is sandwiched between the first layer of glass 1 and the second layer of glass 2. The window glass adopts a double-layer glass structure, and the electric heating layer is sandwiched between the first layer of glass 1 and the second layer of glass 2, which is beneficial to ensuring the safety and protection effect of the electric heating layer; during the process of lifting or flipping and opening and closing the window glass, there will be no situation where the glass water cut scratches and rubs the electric heating layer, thereby improving the service durability of the electric heating layer.
[0039] Of course, there are a variety of different structural solutions for the above electric heating layer to choose from; for example, an electric heating wire element can be fixed on a thin sheet with good thermal conductivity to form an electric heating layer, and the above electric heating layer is clamped and fixed in the middle by the first layer of glass 1 and the second layer of glass 2. In this embodiment, the electric heating layer includes an adhesive film 3 that can adhere to the glass surface and an electric heating wire 40 arranged on the adhesive film 3, and both ends of the electric heating wire 40 extend to the same side edge of the window glass; correspondingly, the electrical connection part includes a positive tongue piece 41 and a negative tongue piece 42 respectively connected to both ends of the electric heating wire 40, and the power supply unit includes a positive connection seat that can be circuit-connected to the positive tongue piece 41 and a negative connection seat that can be circuit-connected to the negative tongue piece 42.
[0040] The electric heating layer uses the adhesive film 3 as the base film. The electric heating wire 40 is arranged on the adhesive film 3, and then the adhesive film 3 is used to paste and arrange the electric heating wire 40 on the surface of the glass, which can make the arrangement operation of the electric heating layer on the glass simpler and more convenient, and also ensure the firm adhesion of the electric heating wire 40 on the glass. The electric connection part is divided into two parts: the positive electrode tongue piece 41 and the negative electrode tongue piece 42, and a positive electrode connection seat and a negative electrode connection seat are correspondingly arranged on the power supply unit. When the window glass is closed, the positive electrode tongue piece 41 is docked with the positive electrode connection seat, and the negative electrode tongue piece 42 is docked with the negative electrode connection seat, so as to realize the circuit connection between the power supply unit and the electric heating wire 40, and ensure the stable and reliable circuit connection of the electric heating wire 40.
[0041] Based on the above settings, the electric heating wire 40 in this embodiment is arranged circuitously on the adhesive film 3 and covers the adhesive film 3. According to the heating and defrosting requirements of the entire surface area of the window glass, the entire area of the adhesive film 3 is covered with the electric heating wire 40, and the electric heating wire 40 is arranged in a circuitous form. Finally, the two ends of the electric heating wire 40 can be circuitously returned to the edge on the same side of the window glass, thus providing convenient conditions for connecting with the two electric connection parts also at the edge on this side. For the specific circuitous arrangement form of the electric heating wire 40, of course, it can be reasonably set. Preferably, it adopts the arrangement form as Figure 4 shown; the electric heating wire 40 is arranged along the length direction of the window glass, bends and circuitously on one side of the window glass, the electric heating wire 40 that reaches the bottom of the window glass bends upward, extends along the side of the window glass to the top side of the window glass, and the two ends of the electric heating wire 40 are respectively connected to the positive electrode tongue piece 41 and the negative electrode tongue piece 42 located on this side.
[0042] The spacing size between adjacent parallel electric heating wires 40 can be reasonably set according to the heating power of the electric heating wire 40, and is preferably set between 3 cm and 10 mm.
[0043] And it should be pointed out that there are various alternative technical solutions for the above-mentioned adhesive film 3. For example, ordinary mucosal materials can be used; preferably, the adhesive film 3 in this embodiment uses PVB film. The PVB material has excellent flexibility and flexural properties, and the film made from it is suitable for making the interlayer material of safety glass, which can ensure the transparency and impact resistance of the safety glass.
[0044] For the specific structures and settings of the positive electrode tongue piece 41 and the negative electrode tongue piece 42, there are of course also various structural forms. In this embodiment, as Figure 4 、 Figure 5 and in combination with Figure 6As shown, both the positive electrode tab 41 and the negative electrode tab 42 are wrapped around the edge portion of the window glass. Wrapping both the positive electrode tab 41 and the negative electrode tab 42 around the edge portion of the window glass can prevent the tabs from warping or being scratched and damaged; it also provides good conditions for the tabs to abut and connect with the power supply unit.
[0045] Specifically, in this embodiment, the positive electrode tab 41 is wrapped around the first layer of glass 1, and the negative electrode tab 42 is wrapped around the second layer of glass 2. By wrapping the positive electrode tab 41 and the negative electrode tab 42 around the first layer of glass 1 and the second layer of glass 2 respectively, and staggering the positive electrode tab 41 and the negative electrode tab 42, it is not only convenient to identify the tabs of different polarities, but also helps to increase the spacing distance between the two tabs and prevent short - circuit of the circuit.
[0046] Moreover, relative to the portion connecting the end of the electric heating wire 40, the portions where the positive electrode tab 41 of this embodiment is wrapped around the first layer of glass 1 and the negative electrode tab 42 is wrapped around the second layer of glass 2 are both widened. For the root position where the tab connects the electric heating wire 40, since it is within the spaced - apart space formed between the first layer of glass 1 and the second layer of glass 2, its diameter size can be made slightly larger. While for the portion of the tab wrapped around the edge of the window glass, it adopts a thin - sheet shape. Therefore, by increasing its width size, the consistency of the overall electrical conductivity of the tab can be ensured; at the same time, widening the wrapped portion of the tab is also beneficial to increasing the contact area between the tab and the connecting seat, thereby ensuring the reliability and stability of the electrical connection.
[0047] In addition, as Figure 4 and Figure 5 shown, both the positive electrode tab 41 and the negative electrode tab 42 of this embodiment are arranged on one side in the height direction of the window glass, and the positive electrode tab 41 and the negative electrode tab 42 are respectively arranged close to both sides in the width direction of the window glass. It can be seen that arranging the positive electrode tab 41 and the negative electrode tab 42 at adjacent positions on both sides in the width direction of the window glass is beneficial to increasing the spacing distance between the positive electrode tab 41 and the negative electrode tab 42 as much as possible, thereby preventing short - circuit connection between the two tabs.
[0048] In summary, for the heating structure of the mobile window glass in this embodiment, an electrical connection part for supplying power to the electrothermal layer is provided at one edge of the window glass, and a power supply unit is correspondingly provided on the window frame; when the window glass is closed, the power supply unit is brought into abutting connection with the electrical connection part to realize the electrical connection between the power supply unit and the electrothermal layer, so that the window glass in the closed state can be powered and heated to realize the defrosting function; when the window glass is in the open state, the window glass does not need to be defrosted, the circuit is in an open state, and there is no connection and entanglement of wires between the window glass and the window frame, ensuring the circuit safety of the electrothermal layer of the window glass, thereby providing an electrothermal power supply solution suitable for being arranged on the mobile window glass.
[0049] Embodiment 2
[0050] This embodiment relates to a vehicle, and the vehicle in this embodiment adopts the heating structure of the mobile window glass provided in Embodiment 1.
[0051] By adopting the heating structure provided in Embodiment 1 on any window glass of the vehicle, during the lifting movement of the window glass, since the electrothermal wire 40 is not on the outer layer of the window glass, there is no need to worry that the electrothermal wire 40 will be worn due to the movement of the glass, resulting in the failure of the defogging function. At the same time, since the docking of the electrical connection part and the power supply unit is only realized when the window glass is closed, there is no wire connection and entanglement during the opening and movement of the window glass. Therefore, there is no need to adopt the traditional wire harness power supply, avoiding the abnormal noise or rubbing caused by the long-distance non-fixed wire harness, and further preventing the occurrence of electric leakage or short circuit. Moreover, the adhesive film 3 adopts a PVB film, which can also improve the sound insulation effect of the window glass.
[0052] Furthermore, an electrical connection part for supplying power to the electrothermal layer is provided at one edge of the window glass, and a power supply unit is correspondingly provided on the window frame; when the window glass is closed, the power supply unit is brought into abutting connection with the electrical connection part to realize the electrical connection between the power supply unit and the electrothermal layer, so that the window glass in the closed state can be powered and heated to realize the defrosting function; when the window glass is in the open state, the window glass does not need to be defrosted, the circuit is in an open state, and there is no connection and entanglement of wires between the window glass and the window frame, ensuring the circuit safety of the electrothermal layer of the window glass, thereby providing an electrothermal power supply solution suitable for being arranged on the mobile window glass.
[0053] The above are only the preferred embodiments of the present utility model. The explanations of the detailed configuration, the examples of specific structural settings, or the descriptions of the assembly and connection methods are all for the need of full disclosure, so that those skilled in the art can better implement the present utility model, rather than to limit the protection scope of the present utility model. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
