DETAILED DESCRIPTION
[0030] The following will be described in detail with reference to the accompanying drawings Figs. 1-3 The present application is further described in detail.
[0031] The embodiment of the present application discloses a novel motor train heating glass. Referring to Figs. 1 to 3 , comprising outer glass 1, middle glass 2 and inner glass 3, one side of the middle glass 2 is arranged opposite to the outer glass 1, and the other side of the middle glass 2 is arranged opposite to the inner glass 3. The outer glass 1 is provided with a plurality of outer heating areas 11 and a plurality of outer transition areas 12 on the side facing the middle glass 2, there is an outer transition area 12 between adjacent outer heating areas 11, and there is an outer heating area 11 between adjacent outer transition areas 12. The inner glass 3 is provided with a plurality of inner heating areas 31 and a plurality of inner transition areas 32 on the side facing the middle glass 2, there is an inner transition area 32 between adjacent inner heating areas 31, and there is an inner heating area 31 between adjacent inner transition areas 32. The outer heating area 11, the inner heating area 31, the outer transition area 12 and the inner transition area 32 are all parallel to each other, the outer heating area 11 is arranged opposite to the inner transition area 32, and the inner heating area 31 is arranged opposite to the outer transition area 12. One outer heating wire 4 is arranged on each outer heating area 11, and one inner heating wire 5 is arranged on each inner heating area 31. The inner heating wire 5 and the outer heating wire 4 are arranged staggered, so that the inner heating wire 5 and the outer heating wire 4 are not densely arranged, the heat transfer difference between the inner heating wire 5 and the outer heating wire 4 is reduced, the heat can be uniformly distributed on the inner glass 3 and the outer glass 1, and the situation that the visual effect is poor due to local overheating is reduced. The PVB film 21 is installed on both sides of the middle glass 2, and the outer heating wire 4 and the inner heating wire 5 are attached to the PVB film 21. The outer heating wire 4 heats the outer glass 1, and the inner heating wire 5 heats the inner glass 3, so that the effect of independently heating the outer glass 1 and the inner glass 3 is realized. In this way, the specific power of the outer heating wire 4 and the specific power of the inner heating wire 5 can be controlled within a suitable range, the situation that the visual effect is reduced due to the too high specific power of the heating wire is reduced, and the risk that the motor train glass is cracked due to the large temperature difference between the inside and outside of the motor train glass is also reduced.
[0032] In order to make the outer heating wire 4 and the inner heating wire 5 work independently, referring to Figs. 1 to 3The outer heating wire 4 is connected to the outer power line 42 through the outer copper bus 41, and the outer power line 42 supplies power to the outer heating wire 4. The inner heating wire 5 is connected to the inner power line 52 through the inner copper bus 51, and the inner power line 52 supplies power to the inner heating wire 5.

The outer power line 42 is led out near the top of the middle glass 2, and the outer power line 42 is coated with a red pigment as an outer identification layer 421 on the outer wall. It serves to identify the power line as the outer power line 42, reducing the risk of wiring errors of the outer power line 42. The inner power line 52 is led out near the bottom of the middle glass 2, and the inner power line 52 is coated with a green pigment as an inner identification layer 521 on the outer wall. It serves to identify the power line as the inner power line 52, reducing the risk of wiring errors of the inner power line 52.

[0035] In order to reduce the risk of glass fragments injuring people, with reference to Fig. 1 , the splash-proof layer 7 is installed on the side of the inner glass 3 away from the middle glass 2. When the motor train glass breaks, the splash-proof layer 7 reduces the risk of glass fragments splashing and injuring people.
[0036] The implementation principle of the novel motor train heating glass embodiment of the present application is that: the outer heating wire 4 heats the outer glass 1, and the inner heating wire 5 heats the inner glass 3, so that the outer glass 1 and the inner glass 3 are independently heated. The inner heating wire 5 and the outer heating wire 4 are arranged staggeredly, so that the inner heating wire 5 and the outer heating wire 4 are not densely arranged, the heat transfer difference between the inner heating wire 5 and the outer heating wire 4 is reduced, the heat can be uniformly distributed on the inner glass 3 and the outer glass 1, and the situation that the visual effect is poor due to local overheating is reduced. Moreover, the outer glass 1 and the inner glass 3 are independently heated, the specific power of the outer heating wire 4 and the specific power of the inner heating wire 5 are controlled within a proper range, the situation that the visual effect is reduced due to the specific power of the heating wire being too high is reduced, and the risk that the motor train glass appears to be cracked due to a large temperature difference between the inner and outer motor train glasses is reduced.
