Detailed Description

In order that the above objects, features and advantages of the present disclosure may be more clearly understood, a further description of aspects of the present disclosure will be provided below. It should be noted that, without conflict, the embodiments of the present disclosure and features in the embodiments may be combined with each other.

In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present disclosure, but the present disclosure may be practiced otherwise than as described herein; it will be apparent that the embodiments in the specification are only some, but not all, embodiments of the disclosure.

An embodiment of the present disclosure provides a vehicle glass, and fig. 1 is a schematic structural diagram of the vehicle glass provided by the embodiment of the present disclosure, where, as shown in fig. 1, the vehicle glass includes: a glass body 1 and a heating wire 2. The glass body 1 includes a magnetically susceptible material whose light transmission characteristic varies with the magnetic field characteristic.

The glass body 1 includes a windshield wiring area 11; the heating wire 2 is laid in the windshield wiring area 11 of the glass body 1.

The windshield wiring area 11 is provided with a first sub-heating wire 21 and a second sub-heating wire 22; when the electric heating is performed, the magnetic fields generated by the first sub-heating wire 21 and the second sub-heating wire 22 cancel each other.

The glass body 1 includes therein a magnetically susceptible material (not shown in the drawings) whose light transmission characteristic varies with the magnetic field characteristic, and the magnetically susceptible material may include metal ions or the like. The existence of the magnetic induction material can improve the heat insulation effect of the vehicle glass and also can improve the condition that the vehicle glass is easy to break. Wherein the metal ion is silver ion or magnesium ion, etc. When the heating wire is electrified, a magnetic field is generated around, and the light perspective characteristic of the magnetic induction material is changed along with the characteristic of the surrounding magnetic field, for example, the arrangement of the magnetic induction material is changed, so that the transmission path is affected by the light perspective characteristic when light passes through the glass body 1, the imaging effect of the area is further affected, and virtual images or other conditions can possibly appear in the final imaging everywhere.

The glass body 1 includes a windshield wiring area 11, and heating wires are laid in the windshield wiring area 11. The current generated after the heating wire is electrified can form a magnetic field around, the magnetic induction material can change the light projection characteristic by the magnetic field characteristic, and the light needs to pass through the windshield wiring area 11, so that the magnetic induction material can influence imaging, and the condition of ghost shadow is caused.

Accordingly, the first sub-heating wires 21 and the second sub-heating wires 22 are laid in the windshield wiring area 11. When the heating wires are electrified and heated, the magnetic fields generated by the first sub-heating wires 21 and the second sub-heating wires 22 can cancel each other. When the direction of the magnetic field generated by the first sub-heating wire 21 is opposite to the direction of the magnetic field generated by the second sub-heating wire 22 and the magnetic fields are the same, the magnetic fields generated by the two sub-heating wires can be counteracted. Even if the heating wire is electrified, the magnetic induction material in the windshield wiring area 11 is not affected, the magnetic induction material is not affected by the magnetic field, and the imaging effect is relatively clear.

Alternatively, when the current direction of the first sub-heating wire 21 is opposite to the current direction of the second sub-heating wire 22 and the current is the same, the magnetic field direction formed by the first sub-heating wire 21 and the magnetic field direction formed by the second sub-heating wire 22 are opposite, and the magnetic field strength is the same, and the two magnetic field characteristics are opposite and can cancel each other. As shown in fig. 1, the first and second sub-heating wires 21 and 22 in the windshield wiring area 11 are two heating wires, and the current directions are opposite (as shown by the arrow), and the current magnitudes are the same, so that the two magnetic fields generated by the current are offset, and the magnetic induction material is prevented from being influenced by the change of the magnetic field characteristics. The corresponding imaging of the windshield wiring area is clearer, and if the light rays are successfully acquired by human eyes or corresponding image acquisition devices after exiting from the area, the corresponding imaging area is not virtual.

The heating wire may be formed by silver paste plating. Or a resistance wire is used as the heating wire, and a heating wire embedding mode is adopted, for example, alloy, tungsten wire and the like are used. Other materials can be adopted as the heating wire, and the heating requirement of the vehicle glass can be met.

In the embodiment of the disclosure, the glass body contains a magnetic induction material, and the magnetic induction material is influenced by current, so that the magnetic field characteristics of the magnetic induction material are changed, and the magnetic induction material moves in the windshield to influence the transmission of light, so that the problem of image blurring is caused. Therefore, according to the embodiment of the disclosure, the first sub-heating wire and the second sub-heating wire are distributed in the windshield wiring area of the glass body, so that the magnetic field generated by electrifying the first sub-heating wire and the magnetic field generated by electrifying the second sub-heating wire can be mutually offset, and the influence of the magnetic field on the magnetic induction material in the glass body is eliminated. The light rays passing through the windshield wiring area are not influenced by the magnetic induction material, so that the imaging of the windshield wiring area is clear, and the phenomenon that the acquired image is unclear to influence the driving experience of a user is avoided.

In some embodiments, fig. 2 is a schematic structural diagram of still another vehicle glass provided in an embodiment of the disclosure, as shown in fig. 2, where the number of heating wires 2 is one;

The heating wires 2 are laid in a back and forth folded arrangement to form a first sub-heating wire 21 and a second sub-heating wire 22 in the windshield wiring area 11.

In connection with the above embodiment, the number of heating wires in the windshield wiring area 11 is one. Referring to fig. 2, the same heating wire 2 is laid in the windshield wiring area 11 in a round trip folded layout, and the round trip folded heating wire forms a first sub-heating wire 21 and a second sub-heating wire 22 (the first sub-heating wire 21 and the second sub-heating wire 22 belong to different positions on the same heating wire). When the heating wire is electrified and heated, current flows through the heating wire, and as the first sub-heating wire 21 and the second sub-heating wire 22 are in a reciprocating folding relationship, the directions of the current flowing through the first sub-heating wire 21 and the second sub-heating wire 22 are opposite, and the current is the same (as the arrow in fig. 3 shows the current direction), so that two magnetic fields generated by the current can be mutually offset, and the influence of the magnetic field characteristic change of the magnetic induction material on the light projection characteristic of the magnetic induction material is avoided.

In some embodiments, fig. 3 is a schematic structural diagram of still another vehicle glass provided in an embodiment of the disclosure, and as shown in fig. 3, the glass body 1 further includes a forbidden region 12.

At least a first sub-area 111 in the windshield wiring area 11 is provided with a first sub-heating wire 21 and a second sub-heating wire 22, and the first sub-area 111 is a sub-area adjacent to the forbidden band area 12 in the windshield wiring area 11.

The glass body 1 includes a windshield wiring area 11 and a no-cloth area 12. Wherein, the heating wire is arranged in the windshield wiring area 11, but the heating wire is not arranged in the forbidden area 12, and when the heating wire is not arranged in the forbidden area 12, the condition that the magnetic field influences the light transmission characteristic of the magnetic induction material in the area is not existed.

The heater wire 2 in the windshield wiring area 11 can provide sufficient heat for the vehicle glass when defrosting and defogging by heating with the heater wire is required. The heating wire 2 does not exist in the cloth-forbidden region 12, the cloth-forbidden region 12 is a light-transmitting region which is not shielded by the heating wire 2, light does not contact the heating wire 2 when passing through the cloth-forbidden region 12, refraction is not caused by the influence of the heating wire 2, and a transmission path of the light when passing through the cloth-forbidden region 12 of the glass body 1 is not changed. Because the heating wire 2 does not exist in the cloth-forbidden region 12, the magnetic induction material in the range of the cloth-forbidden region 12 cannot be influenced by the magnetic field generated by the electrifying of the heating wire, and therefore no virtual shadow is generated. Therefore, the imaging corresponding to the forbidden area 12 is clearer, and if the light rays are successfully acquired by human eyes or corresponding image acquisition devices after exiting from the area, dark patterns can not appear in the corresponding imaging area.

But the windshield wiring area 11 may be provided with heating wires at a position adjacent to the no-go area 12. The current generated after the heating wire is electrified can form a magnetic field around, and because the area is close to the forbidden region 12, the magnetic induction material at the edge of the forbidden region 12 can be changed in light projection characteristic by the magnetic field characteristic, and if light passes through the edge area of the forbidden region 12, the program effect can be affected, and the virtual shadow condition occurs. The windshield wiring area 11 is adjacent to the cloth forbidden area 12 and is a first sub-area 11, a first sub-heating wire 21 and a second sub-heating wire 22 are arranged in the first sub-area 111, and when the electric heating is performed, magnetic fields generated by the first sub-heating wire and the second sub-heating wire are counteracted so as to eliminate the influence of the magnetic fields. For example, when the heating wires are electrically heated, the magnetic fields generated by the first sub-heating wires 21 and the second sub-heating wires 22 may cancel each other. When the direction of the magnetic field generated by the first sub-heating wire 21 is opposite to the direction of the magnetic field generated by the second sub-heating wire 22 and the magnetic fields are the same, the magnetic fields generated by the two sub-heating wires can be counteracted. Even if the heating wire is electrified, the magnetic induction material in the range of the first subarea 111 is not influenced, and the magnetic induction material is not influenced by a magnetic field, so that the imaging effect of the forbidden area 12 adjacent to the first subarea 111 is clearer.

In some embodiments, the first and second sub-heater wires are layered and routed in the windshield routing area.

An insulating isolation layer is arranged between the first sub-heating wire and the second sub-heating wire.

In the embodiment of the present disclosure, when the first sub-heating wires and the second sub-heating wires are laid out in the windshield wiring area, a manner of laying them out in layers may also be adopted. The first sub-heating wire and the second sub-heating wire are arranged at the same position, and an insulating isolation layer is arranged between the first sub-heating wire and the second sub-heating wire, so that the short circuit between the first sub-heating wire and the second sub-heating wire is avoided, and the safety problem is solved. The current directions of the first sub-heating wires and the second sub-heating wires which are arranged in a laminated way are opposite, and the current is the same, so that two magnetic fields generated by the currents can be mutually offset, and the influence of the magnetic field characteristic change on the light projection characteristic of the magnetic induction material is avoided. And because the heating wires are arranged in a laminated way, the area of the glass body where the heating wires are arranged is reduced, the light-transmitting area of the glass body which is not shielded by the heating wires is enlarged, and the visual field of a driver is more facilitated.

In some embodiments, fig. 4 is a schematic structural diagram of still another vehicle glass provided in an embodiment of the present disclosure, and as shown in fig. 4, the first sub-heating wires 21 and the second sub-heating wires 22 are arranged in a manner close to parallel arrangement in the windshield wiring area 11.

In combination with the above embodiment, in the embodiment of the present disclosure, the first sub-heating wire 21 and the second sub-heating wire 22 are arranged in the windshield wiring area 11 in a manner of being arranged in close parallel, and referring to fig. 4, the first sub-heating wire 21 and the second sub-heating wire 22 are in a parallel relationship and have a smaller distance therebetween. When the heating wires are used for heating, the current directions of the first sub-heating wires and the second sub-heating wires are opposite, and the current sizes are the same, so that two magnetic fields generated by the currents can be mutually offset, and the influence of the magnetic field characteristics on the light projection characteristics of the magnetic induction materials due to the change of the magnetic field characteristics is avoided. The area of laying the heating wires on the glass body can be reduced when the glass body is arranged in parallel, the light-transmitting area of the glass body, which is not shielded by the heating wires, is enlarged, and heat can be transferred to the periphery more uniformly.

It should be noted that, the number and shape of the heating wires in the windshield wiring area are not limited in the embodiment of the disclosure, and the requirements that the magnetic fields generated by energizing the heating wires can be mutually offset are met, and the rest can be set according to actual requirements. For example, after the heating wires are arranged, the generated magnetic fields can be mutually offset, and the influence of the magnetic field characteristic change on the light projection characteristic of the magnetic induction material can be avoided.

In some embodiments, fig. 5 is a schematic structural view of still another vehicle glass provided in an embodiment of the present disclosure, and as shown in fig. 5, the glass body 1 includes a glass layer 13 and an insulating interlayer 14 disposed between the glass layers 13. The heating wire 2 is arranged between at least one glass layer 13 and an insulating interlayer 14.

In the disclosed embodiment, the glass body includes glass layers 13 and insulating interlayers 14, the insulating interlayers 14 being disposed between the glass layers 13. Insulating interlayer 14 may be PVB, which has good safety, sound insulation, transparency, and uv resistance; the material can also be an ionic intermediate film (SentryGlasPlus, SGP) which has higher water resistance, structural strength performance, colorless transparency and the like; and the ethylene-vinyl acetate copolymer (EVA) also can be called high polymer resin, and has good fluidity, low melting temperature and corrosion resistance.

When there is insulating intermediate layer 14, can lay heater strip 2 between at least one deck glass layer 13 and insulating intermediate layer 14, accessible glass layer 13 or glass layer 13 and insulating intermediate layer 14 are isolated heater strip 2 with the user, avoid heater strip 2 to set up in glass body 1 outside, and the user can directly touch heater strip 2, causes the safety problem easily. Simultaneously, the heater strip 2 can be more quick with the glass layer 13 of heat transfer to both sides, improves heating rate, and then accelerates defrosting defogging efficiency. In some scenes, a silver paste electroplating mode or a heating wire embedding mode is adopted when the heating wire arrangement is carried out, and the structure provided by the embodiment of the disclosure can be suitable for the arrangement mode.

In some embodiments, fig. 6 is a schematic structural view of yet another vehicle glass provided in an embodiment of the present disclosure, as shown in fig. 6, the glass body includes a glass layer 13 and a conductive interlayer 15 disposed between the glass layers 13. The heating wire 2 is arranged on the inner side surface of the inner glass layer, which is the surface facing the cabin of the vehicle when the vehicle glass is installed on the vehicle.

In the disclosed embodiment, the glass body includes glass layers 13 and a conductive interlayer 15, the conductive interlayer 15 being disposed between the glass layers 13. The conductive interlayer 15 may include metal ions such as silver ions, magnesium ions, etc., and the conductive interlayer 15 is formed by coating reflective silver, for example. The conductive interlayer 15 can increase the heat insulation, ultraviolet resistance and other functions of the vehicle glass, and the subsequent steps of sticking a reflective film to the vehicle glass are not needed.

When the conductive interlayer 15 exists, the metal ions in the conductive interlayer 15 can be influenced by the magnetic field generated after the heating wire is heated, the metal ions can move under the influence of the magnetic field, and if the metal ions in the conductive interlayer 15 corresponding to the windshield wiring area move to the position of the conductive interlayer 15 corresponding to the forbidden area, the light transmission characteristic of the forbidden area can be influenced. To avoid this, referring to fig. 6, the heating wire 2 is laid on the inner side of the inner glass layer, which is the side facing the cabin of the vehicle when the vehicle glass is mounted on the vehicle. At this time, the heating wire 2 is not in contact with the conductive interlayer 15, and the inner glass layer insulates the two. By increasing the distance between the heating wire 2 and the conductive interlayer 15, the influence of the magnetic field generated by the heating wire 2 on the metal ions in the conductive interlayer 15 is weakened, so that the possibility of moving the metal ions is reduced.

In the above embodiments, the heating wires are not arranged on the outer side surface of the outer glass layer, which is the surface facing the external environment when the vehicle glass is mounted on the vehicle. Because the one surface facing to the external environment is directly contacted with the external environment, if the heating wire is arranged at the position, the heating wire is easy to damage, the service life is shorter, and the heating wire is not arranged on the outer side surface of the outer glass layer.

In some embodiments, the routing density of the heating wires laid out in at least a second sub-region of the windshield routing area remains uniform, the second sub-region being a sub-region of the windshield routing area remote from the keep-out region.

In the embodiment of the disclosure, the wiring density of the heating wires laid in at least the second sub-area in the windshield wiring area is kept uniform, so that the lengths of the heating wires laid in the second sub-area can be kept uniform. Because the heating power is the same when the heating wires are heated, the heat generated by the heating wires in each unit length is the same, and the heat generated by the heating wires in the same length is also the same. When the wiring density of the heating wires in the unit area is kept uniform, the heat generated by the heating wires in the unit area is the same. Then lay the heater strip in this mode in the second subregion, can make the heater strip heat when heating, the heat that the second subregion everywhere produced is more even, and the glass body is heated more evenly, and defrosting defogging effect is better.

In some embodiments, the heater wire is routed in a wavy fold, a triangular fold, or a straight reciprocating line at the windshield routing area.

In the embodiment of the disclosure, the heating wires can be distributed in the forbidden cloth area in different wiring modes, such as a wave fold line, a triangle fold line or a reciprocating straight line mode, and different heat demands of the vehicle glass can be met according to the length of the provided heating wires.

Exemplary, fig. 7 is a schematic diagram of a heating wire wiring method according to an embodiment of the present disclosure, and as shown in fig. 7, the heating wire is wired in a wavy fold line manner, and in this way, the length of the heating wire in a unit area can be increased, so that the heat generated by the heating wire in the unit area is improved. Fig. 8 is a schematic diagram of another embodiment of a wire routing method according to the present disclosure, where, as shown in fig. 8, a triangular broken line is used to route the wires, and in this way, the length of the wires in a unit area may be increased, so as to increase the heat generated by the wires in the unit area. Fig. 9 is a schematic diagram of another embodiment of a heating wire wiring method, as shown in fig. 9, in which a reciprocating straight line is used to wire the heating wire, so that the usage amount of the heating wire can be reduced, and the cost is saved. The above wiring modes are all exemplified, only one wiring mode of the heating wire is exemplified, the wiring mode can be selected according to actual requirements, and other modes can be adopted for wiring, which is not limited in the embodiment of the disclosure, and the number of the heating wires is not limited.

The power supply control module is used for receiving the heating parameters and controlling the heating wire to be turned off when the heating parameters exceed a set threshold value.

The working parameters at least comprise temperature, for example, the detection module comprises a temperature sensor, the temperature of the heating wire on the window glass is detected in real time through the temperature sensor, when the detected temperature exceeds a set temperature threshold value, the power supply control module controls the heating function of the heating wire to be closed, and the window glass is prevented from being too high in temperature and scalding a user.
