[0028] This embodiment discloses a glass electric heating device, such as Figure 1 , Figure 4 As shown, it may include:
[0029] Box assembly 02, box assembly 02 includes control box 21, plug-in unit 22, line unit 23; control box 21 includes first shell 211, second shell 212, base 213, first chamber 214, second chamber 215; one end of first shell 211 is fixedly connected with one end of second shell 212; first shell 211 is configured as an open hollow structure; second shell 212 is configured as an open hollow structure; base 213 is fixedly connected with the open side of one end of first shell 211, and surrounds first shell 211 to form a first chamber 214; the base 213 is fixedly connected to the open side of one end of the second shell 212, and is surrounded by the second shell 212 to form a second chamber 215; the first chamber 214 is communicated with the second chamber 215; the plug-in unit 22 is detachably connected to the first shell 211; part of the plug-in unit 22 is arranged in the first chamber 214; the line unit 23 is detachably connected to the second shell 212; part of the line unit 23 is arranged in the first chamber 214; part of the line unit 23 is arranged in the second chamber 215; the line unit 23 is electrically connected to the plug-in unit 22;
[0030] The colloid component 03 includes a first adhesive portion 31 and a second adhesive portion 32 ; the first adhesive portion 31 is bonded to a side of the base 213 away from the first shell 211 ; the second adhesive portion 32 is disposed in the second chamber 215 , blocking the first chamber 214 from communicating with the outside of the first chamber 214 through the second chamber 215 .
[0031] In this embodiment, one end of the glass electric heating device can be connected to the heating wire of the aircraft glass, and the other end can be connected to the electrical system of the spacecraft, and can be used to heat the aircraft glass to eliminate fog. Usually, the part of the glass electric heating device connected to the heating wire of the aircraft glass is directly fixed to the aircraft glass by an adhesive and insulated by the adhesive. With the long-term use of the aircraft, this setting method will cause the glass electric heating device to be unstable and generate fog to short-circuit the glass electric heating device, and thus a glass electric heating device is proposed. Figure 1 , Figure 4As shown, the glass electric heating device may include a box assembly 02 and a colloid assembly 03. The box assembly 02 may include a control box 21, a plug-in unit 22, and a line unit 23. The control box 21 may include a first shell 211, a second shell 212, a base 213, a first chamber 214, and a second chamber 215. One end of the first shell 211 may be fixedly connected to one end of the second shell 212. The fixed connection as one body may make the connection between the first shell 211 and the second shell 212 more stable, thereby achieving the effect of improving the strength of the glass electric heating device. The first shell 211 may be set as an open hollow structure, which may provide sufficient installation space for the combination of other components and the first shell 211, thereby realizing the compactness of the glass electric heating device. The second shell 212 may be set as an open hollow structure, which may provide sufficient installation space for the combination of other components and the second shell 212, thereby promoting the further compactness of the glass electric heating device. The base 213 can be fixedly connected to the open side of one end of the first shell 211. The fixed connection as one body can improve the connection strength between the base 213 and the first shell 211, and can achieve the effect of improving the durability of the control box 21. The base 213 can surround the first shell 211 to form a first chamber 214. When other components are assembled with the first shell 211, the first chamber 214 not only has enough space, but the base 213 can also isolate other components from the glass assembly 01, so as to prevent the fog generated by the different temperatures of the glass assembly 01 inside and outside the cabin from affecting the operation of the glass electric heating device.
[0032] The base 213 can be fixedly connected to the open side of one end of the second shell 212. The fixed connection as an integral body can improve the connection strength between the base 213 and the second shell 212, and can achieve the effect of improving the durability of the control box 21. The base 213 can be surrounded by the second shell 212 to form a second chamber 215. The second chamber 215 not only has enough space, but also can use the base 213 to isolate other components from the glass assembly 01, so as to prevent the fog generated by the different temperatures of the glass assembly 01 inside and outside the cabin from affecting the operation of the glass electric heating device.
[0033] The plug-in unit 22 can be detachably connected to the first shell 211. When the glass electric heating device is damaged, the plug-in unit 22 can be quickly separated from the first shell 211, which is convenient for staff to troubleshoot.
[0034] Part of the plug-in unit 22 can be disposed in the first chamber 214 to supply power to the glass electric heating device so that the glass electric heating device can operate normally.
[0035] The circuit unit 23 can be detachably connected to the second housing 212. When the glass electric heating device is damaged, the circuit unit 23 can be quickly separated from the second housing 212, which is convenient for the staff to troubleshoot. Part of the circuit unit 23 can be arranged in the first chamber 214, and part of the circuit unit 23 can be arranged in the second chamber 215. The circuit unit 23 is electrically connected to the plug-in unit 22, and the first chamber 214 can be connected to the second chamber 215. In this arrangement, the control box 21 can properly protect the plug-in unit 22 and the circuit unit 23, so that the connection between the plug-in unit 22 and the circuit unit 23 is not easily affected by external forces.
[0036] The adhesive component 03 may include a first adhesive portion 31 and a second adhesive portion 32. The first adhesive portion 31 may be bonded to a side of the base 213 away from the first shell 211. When the glass electric heating device needs to be loaded into an aircraft, one side of the first adhesive portion 31 may be bonded to the glass component 01, so that the base 213 and the glass component 01 remain relatively fixed, so that the glass electric heating device can operate stably. The second adhesive portion 32 may be disposed in the second chamber 215, and may block the first chamber 214 from being connected to the outside of the first chamber 214 through the second chamber 215, so as to prevent the glass component 01 from having a large temperature difference between the inside and outside of the cabin, thereby generating fog and causing a short circuit in the glass electric heating device.
[0037] In some embodiments, Figure 5 As shown, the control box 21 further includes a bonding groove 217 ; the bonding groove 217 is disposed on a side of the base 213 away from the first shell 211 , and is recessed from the side wall of the base 213 toward the first shell 211 .
[0038] In this embodiment, if Figure 5 As shown, the control box 21 may further include a bonding groove 217. The bonding groove 217 may be provided on a side of the base 213 away from the first shell 211, and may be recessed from the side wall of the base 213 toward the first shell 211. When the control box 21 is bonded to the glass assembly 01, the first adhesive portion 31 may have a larger contact area with the side of the base 213 away from the first shell 211, thereby improving the connection strength between the control box 21 and the glass assembly 01. When the control box 21 and the glass assembly 01 are bonded, and are subjected to a force parallel to the connection surface of the control box 21 and the glass assembly 01, the first adhesive portion 31 embedded in the bonding groove 217 may prevent the control box 21 and the glass assembly 01 from relative displacement.
[0039] In some embodiments, Figure 5 As shown, the length direction of the bonding groove 217 extends in a spiral involute.
[0040] In this embodiment, if Figure 5As shown, the length direction of the bonding groove 217 can extend in a spiral involute, so that the first adhesive portion 31 can be embedded in the length direction of the bonding groove 217 and extend in a spiral involute. After the control box 21 and the glass component 01 are bonded, they are subjected to forces in multiple directions parallel to the connection surfaces of the control box 21 and the glass component 01. This arrangement can prevent the control box 21 and the glass component 01 from relative displacement, thereby achieving the effect of improving the connection strength.
[0041] In some embodiments, Figure 3 As shown, 0.3*D1≥d1, wherein D1 is the thickness of the base 213 and d1 is the depth of the bonding groove 217.
[0042] In this embodiment, if Figure 3 As shown, 0.3 times the thickness of the base 213 can be greater than or equal to the depth of the bonding groove 217, so that the base 213 has sufficient thickness and is not easily bent; it can also avoid excessive first glue part 31 in the bonding groove 217 causing the first glue part 31 to solidify too long, thereby improving processing efficiency.
[0043] In some embodiments, Figure 2 As shown, S1=S2, wherein S1 is the projection area of the first adhesive portion 31 on the connecting plane between the base 213 and the first shell 211, and S2 is the projection area of the base 213 on the connecting plane between the base 213 and the first shell 211.
[0044] In this embodiment, if Figure 2 As shown, the projection area of the first adhesive portion 31 on the connecting plane between the base 213 and the first shell 211 can be equal to the projection area of the base 213 on the connecting plane between the base 213 and the first shell 211, so that the contact area of the first adhesive portion 31 on the connecting plane between the base 213 and the first shell 211 can be maximized, so that the connection between the first shell 211 and the first adhesive portion 31, and the first adhesive portion 31 and the glass component 01 is stable.
[0045] In some embodiments, Figure 2 As shown, 3*D2≤D1, wherein D1 is the thickness of the base 213 and D2 is the minimum thickness of the first adhesive portion 31 .
[0046] In this embodiment, if Figure 2 As shown, the minimum thickness of three times the first adhesive portion 31 can be less than or equal to the thickness of the base 213. This can ensure that the first adhesive portion 31 is used in sufficient quantity and the base 213 and the first adhesive portion 31, as well as the first adhesive portion 31 and the glass component 01 are firmly connected. This can prevent the base 213 and the glass component 01 from shaking easily due to the first adhesive portion 31 being too thick, thereby achieving the effect of improving stability.
[0047] In some embodiments, Figure 2 As shown, S2≥S3+S4, wherein S2 is the projection area of the base 213 on the plane connecting the base 213 and the first shell 211, S3 is the projection area of the first shell 211 on the plane connecting the base 213 and the first shell 211, and S4 is the projection area of the second shell 212 on the plane connecting the base 213 and the first shell 211.
[0048] In this embodiment, if Figure 2 As shown, the projection area of the base 213 on the plane connecting the base 213 and the first shell 211 can be greater than or equal to the sum of the projection area of the first shell 211 on the plane connecting the base 213 and the first shell 211 plus the projection area of the second shell 212 on the plane connecting the base 213 and the first shell 211. In this way, the base 213 can have enough area to contact the glass component 01, and prevent the line unit 23 from directly contacting the glass component 01, which can effectively avoid short circuits caused by fogging due to the large temperature difference between the inside and outside of the cabin of the glass component 01.
[0049] In some embodiments, Figure 2 As shown, L2 ≥ L1*0.2, wherein L1 is the length of the first shell 211 extending in a direction away from the second shell 212 , and L2 is the length of the second shell 212 extending in a direction away from the first shell 211 .
[0050] In this embodiment, if Figure 2 As shown, the length of the second housing 212 extending in the direction away from the first housing 211 can be greater than or equal to 0.2 times the length of the first housing 211 extending in the direction away from the second housing 212, so that the line unit 23 and the plug-in unit 22 have sufficient connection positions and a reasonable usage ratio, so that the glass electric heating device can still maintain stable operation after long-term use. At the same time, this setting method can also minimize the glass electric heating device from affecting the vision of people in the aircraft.
[0051] In some embodiments, Figure 1 As shown, the plug-in unit 22 includes a first plug connector 221 and a second plug connector; the first plug connector 221 is detachably connected to the first shell 211; the first plug connector 221 is arranged in the first chamber 214; the first plug connector 221 is electrically connected to the line unit 23; the second plug connector is detachably connected to the first plug connector 221; part of the second plug connector is arranged in the first chamber 214; the first plug connector 221 is electrically connected to the second plug connector.
[0052] In this embodiment, if Figure 1As shown, the plug-in unit 22 may include a first plug connector 221 and a second plug connector. The first plug connector 221 may be detachably connected to the first housing 211, which may facilitate the modular production of the first plug connector 221 and the first housing 211, so that different models of first plug connectors 221 and first housings 211 may be adapted to each other and easy to disassemble and assemble. The first plug connector 221 may be arranged in the first chamber 214, and the first chamber 214 may protect the first plug connector 221 from external impact. The first plug connector 221 may be electrically connected to the line unit 23. When the glass electric heating device is running, the first plug connector 221 may receive power from the spacecraft power system, and then transmit it to the line unit 23 to complete the heating. The second plug connector may be detachably connected to the first plug connector 221, and part of the second plug connector is arranged in the first chamber 214. The first plug connector 221 may be electrically connected to the second plug connector. When the glass electric heating device needs to be replaced, the staff may separate the second plug connector from the first plug connector 221 to complete the disassembly. This convenient method may improve work efficiency.
[0053] In some embodiments, Figure 1 As shown, the control box 21 further includes a limiting groove 216 ; the limiting groove 216 is disposed on a side of the base 213 close to the second shell 212 , and is recessed from the side wall of the base 213 toward a direction away from the second shell 212 ; a portion of the line unit 23 abuts against the limiting groove 216 .
[0054] In this embodiment, if Figure 1 As shown, the control box 21 may further include a limiting groove 216. The limiting groove 216 may be provided on a side of the base 213 close to the second housing 212, and may be recessed from the side wall of the base 213 toward a direction away from the second housing 212. When the glass electric heating device is assembled, part of the line unit 23 may abut against the limiting groove 216, and the position of each line unit 23 may be fixed. When one end of the line unit 23 away from the first plug connector 221 needs to be connected to other components, the limiting groove 216 may also prevent the line unit 23 from bending.
