For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0039] like Figures 1 to 3 As shown, the embodiment of the present application provides a three-piece sliding window, including a window frame mechanism 10, a heating module 20 and a window glass 30. The window frame mechanism 10 includes a frame 11 and two guide rails 12, and the two guide rails 12 are respectively arranged on opposite sides of the frame 11 in the width direction along the length direction of the frame 11.

[0040] Specifically, the frame 11 is provided with two first windows opposite to each other and a second window between the two first windows along its length direction, and the window glass 30 includes a sliding glass 31 and two fixed glasses 32, and the sliding glass 31 is slidably arranged on the two guide rails 12 and can cover the second window, so that the sliding window function can be realized. When manufacturing the three-piece sliding window, the frame 11, the window glass 30 and the guide rails can be integrally injection molded.

[0041] The two fixed glasses 32 are respectively arranged on opposite sides of the frame 11 along the length direction thereof, specifically, respectively arranged in the two first windows, and the sliding glass 31 can slide along the two guide rails 12 to between the two fixed glasses 32. The two fixed glasses 32 can be respectively embedded and sealed in the two first windows by gluing, which can improve the sealing and assembly stability of the two fixed glasses 32 relative to the two first windows.

[0042] More specifically, the heating module 20 includes two first heating circuits 21 respectively arranged on two fixed glasses 32, and the two first heating circuits 21 are electrically connected through a first wire 23 and a second wire 24 respectively arranged on opposite sides of the width direction of the frame 11. In this way, the two first heating circuits 21 form a heating circuit. The first heating circuit 21 can be connected to an external power source to supply power to it, or the three-piece sliding window can also have its own power supply to supply power to the first heating circuit 21.

[0043] The following is a further description of the three-piece sliding window provided in the embodiment of the present application: When the three-piece sliding window provided in the embodiment of the present application is in operation, the sliding glass 31 slidably mounted on the two guide rails 12 can slide along the length direction of the frame 11, thereby realizing the sliding window function, so that the fixed glass 32 and the sliding glass 31 can be heated by the first heating circuit 21 and the second heating circuit 22 of the heating module 20, thereby realizing the heating function of the three-piece sliding window, and the two first heating circuits 21 are respectively arranged on the opposite sides of the width direction of the frame 11. The first wire 23 and the second wire 24 are electrically connected. In this way, during the integral injection molding process of the three-piece sliding window, even if the installation position of the guide rail 12 coincides with the assembly position of the first wire 23 or the second wire 24, it can only press the first wire 23 or the second wire 24, and cannot press the first wire 23 and the second wire 24 at the same time. In this way, the first heating circuit 21 is prevented from short-circuiting due to the guide rail 12 pressing the wires when working. In this way, the safety hazard of the three-piece sliding window is eliminated, and the safety of the three-piece sliding window is significantly improved.

[0044] In other embodiments of the present application, Figure 3 and Figure 4 As shown, the two first heating circuits 21 each include a first busbar 211 and a second busbar 212 distributed on the edges of the corresponding fixed glass 32, a plurality of first heating wires 213 arranged on the fixed glass 32 are connected between the first busbar 211 and the second busbar 212, the two first busbars 211 are electrically connected via a first wire 23, and the two second busbars 212 are electrically connected via a second wire 24.

[0045] Specifically, when the two first heating circuits 21 are working, the two first busbars 211 are electrically connected via the first wire 23, and the two second busbars 212 are electrically connected via the second wire 24, thereby forming a power-on loop of the two first heating circuits 21. Then, the first heating wire 213 connected between the first busbar 211 and the second busbar 212 can be energized and generate heat, thereby achieving heating of the fixed glass 32.

[0046] Optionally, the first busbar 211 and the second busbar 212 are respectively fixed to the opposite side edges of the fixed glass 32 along the length direction of the frame 11, and each first heating line 213 can be evenly spaced and spread over the entire fixed glass 32. By making the first busbar 211 and the second busbar 212 respectively fixed to the opposite side edges of the fixed glass 32 along the length direction of the frame 11, it is convenient for each first heating line 213 to be horizontally wired from top to bottom on the fixed glass 32 along the width direction of the frame 11. By making each first heating line 213 evenly spaced and spread over the entire fixed glass 32, the heating uniformity of the fixed glass 32 is improved.

[0047] Optionally, the guide rail 12 is an aluminum profile, so that when the guide rail 12 presses against the first heating circuit, it can also absorb the heat emitted by the first busbar 211 and the second busbar 212 in the first heating circuit, thereby further ensuring the heating safety of the first heating circuit.

[0048] In other embodiments of the present application, Figure 5 As shown, the heating module 20 also includes a second heating circuit 22 arranged on the sliding glass 31, the second heating circuit 22 includes a third busbar 221 and a fourth busbar 222, the third busbar 221 and the fourth busbar 222 are both arranged at the edge of the sliding glass 31, and a plurality of second heating wires 225 arranged on the sliding glass 31 are connected between the third busbar 221 and the fourth busbar 222. The three-piece sliding window also includes an electrical contact component 40, the electrical contact component 40 includes two first electrical contact pieces 41, the two first electrical contact pieces 41 are respectively electrically contacted with the third busbar 221 and the fourth busbar 222, and are respectively electrically connected to the first busbar 211 or the second busbar 212 in any one of the first heating circuits 21.

[0049] Specifically, by arranging the second heating circuit 22 on the sliding glass 31, the sliding glass 31 also has a heating function, thereby improving the overall heating performance of the three-piece sliding window. When the second heating circuit 22 is working, when the sliding glass 31 slides to the second window, the third busbar 221 and the fourth busbar 222 of the second heating circuit 22 are respectively in electrical contact with the two first electrical contact pieces 41, thereby realizing the conduction between the second heating circuit 22 and the first heating circuit 21. At this time, the second heating circuit 22 is equivalent to being connected in parallel to the loop formed by the two first heating circuits 21, so that there is no need to supply power to the second heating circuit 22 separately, thereby saving the manufacturing cost of the three-piece sliding window. The two first electrical contact pieces 41 are respectively in electrical contact with the third busbar 221 and the fourth busbar 222, thereby improving the reliability of the electrical contact cooperation between the second heating circuit 22 and the electrical contact assembly 40, and also reducing the implementation cost of the cooperation between the second heating circuit 22 and the electrical contact assembly 40.

[0050] In other embodiments of the present application, Figure 5 As shown, the fourth busbar 222 includes a first sub-wire 223 and a second sub-wire 224. The first sub-wire 223 and the second sub-wire 224 are respectively arranged at the opposite side edges of the sliding glass 31. A plurality of third heating wires 226 are connected between the first sub-wire 223 and the second sub-wire 224. A second heating wire 225 is connected between the first sub-wire 223 and the third busbar 221. The third busbar 221 and the second sub-wire 224 are respectively used to make electrical contact with the two first electrical contact sheets 41.

[0051] Specifically, by making the fourth busbar 222 include the first sub-line 223 and the second sub-line 224, and making the third busbar 221 and the second sub-line 224 respectively electrically contact the two first electrical contact pieces 41, the third heating line 226 and the second heating line 225 are combined to achieve internal series conduction of the second heating circuit 22.

[0052] Optionally, the first sub-line 223 and the second sub-line 224 are arranged opposite to each other, the second sub-line 224 and the third bus bar 221 are located on the same side of the sliding glass 31 and are arranged at intervals, a height difference is formed between the second sub-line 224 and the third bus bar 221, and the length of the third bus bar 221 is close to the length of the sliding glass 31 along the width of the frame 11, so that each second heating line 225 and each third heating line 226 can fully occupy most of the area of ​​the sliding glass 31, thereby achieving sufficient and uniform heating of the sliding glass 31.

[0053] In other embodiments of the present application, Figure 1 , Figure 2 and Figure 6As shown, the electrical contact assembly 40 further includes two second electrical contact pieces 42 , an electrical connection line 43 is connected between the first electrical contact piece 41 and the corresponding second electrical contact piece 42 , and both second electrical contact pieces 42 are electrically connected to the corresponding second busbar 212 .

[0054] Specifically, by providing two second electrical contact pieces 42, the two first electrical contact pieces 41 are electrically connected to the two second electrical contact pieces 42 by means of electrical connecting wires 43, thereby realizing electrical connection between the second heating circuit 22 and the corresponding first heating circuit 21, thereby realizing the second heating circuit 22 being connected in parallel to the loop formed by the two first heating circuits 21.

[0055] In other embodiments of the present application, Figure 1 and Figure 2 As shown, the electrical contact assembly 40 also includes a first protective cover 44 and a second protective cover 45. The first protective cover 44 is disposed on the frame 11 and covers the portions of the two first electrical contact sheets 41 disposed on the frame 11. The second protective cover 45 is disposed on the corresponding fixed glass 32 and covers the two second electrical contact sheets 42.

[0056] Specifically, by providing the first protective cover 44 and the second protective cover 45, the first protective cover 44 and the second protective cover 45 can effectively protect the first electrical contact piece 41 and the second contact piece, preventing the first electrical contact piece 41 and the second contact piece from being affected by external environmental factors and failing, thereby improving the durability and reliability of the three-piece sliding window.

[0057] In other embodiments of the present application, Figure 2 As shown, the three-piece sliding window also includes a power supply 50, and the two first busbars 211 or the two second busbars 212 are electrically connected to the power supply 50. Specifically, by providing the power supply 50, the three-piece sliding window can realize self-powered heating, thereby reducing the dependence on the external power supply device, and by making the two first busbars 211 or the two second busbars 212 electrically connected to the power supply 50, the effective power supply to the loop formed by the two first heating circuits 21 can be realized.

[0058] Alternatively, if Figure 2 and Figure 4As shown, as a specific connection form between the power supply 50 and the two first heating circuits 21, the second busbar 212 corresponding to the electrical contact assembly 40 may specifically include a third sub-line 214 and a fourth sub-line 215, and the third sub-line 214 and the fourth sub-line 215 may be spaced apart at the edge of the corresponding fixed glass 32, a first heating line 213 is connected between the third sub-line 214 and the corresponding first busbar 211, and the third sub-line 214 and the fourth sub-line 215 are electrically connected to the two second electrical contact pieces 42, respectively, the third sub-line 214 is electrically connected to the power supply device through the power supply line, the fourth sub-line 215 is electrically connected to the second busbar 212 of another first heating circuit 21 through the second conductor 24, and the second busbar 212 is electrically connected to the power supply device through the power supply line. In this way, the power supply 50 can effectively supply power to the first heating circuit 21, and the second heating circuit 22 can also be electrically connected to the two first electrical contact pieces 41 when the sliding glass 31 slides to the second window. The two first electrical contact pieces 41 are electrically connected to the third sub-line 214 and the fourth sub-line 215 and the two second electrical contact pieces 42 respectively, thereby realizing the conduction of the second heating circuit 22.

[0059] In other embodiments of the present application, the diameters of the first wire 23 and the second wire 24 are both 1.1 mm to 1.5 mm. Specifically, by setting the diameters of the first wire 23 and the second wire 24 to be 1.1 mm to 1.5 mm, the diameters of the first wire 23 and the second wire 24 are unified, thereby achieving the interchangeability of the first wire 23 and the second wire 24, reducing the cost of replacing the first wire 23 and the second wire 24, and further reducing the manufacturing and maintenance costs of the three-piece sliding window.

[0060] In some other embodiments of the present application, the first heating circuit 21 and the second heating circuit 22 are both silver paste circuits.

[0061] Specifically, by making the first heating circuit 21 and the second heating circuit 22 both silver paste circuits, thanks to the good adhesion and certain resistance value of the silver paste, the first heating circuit 21 and the second heating circuit 22 can achieve stable heating of the fixed glass 32 and the sliding glass 31.
