[0027] To make the objectives, technical solutions, and advantages of the present utility model clearer and more understandable, the present utility model will be further described in detail below in conjunction with the specific embodiments and with reference to the accompanying drawings. It should be understood that these descriptions are merely exemplary and are not intended to limit the scope of the present utility model. In addition, in the following description, the descriptions of well - known structures and technologies are omitted to avoid unnecessarily confusing the concepts of the present utility model.
[0028] To prevent the vehicle interior temperature from becoming too high when the automatic control function of the air conditioner controller fails, which may affect the health and comfort of passengers, a manual refrigeration function independent of the original controller is added.
[0029] To implement the manual refrigeration function, an external control box for the air conditioner cabinet needs to be arranged in the passenger cabin of the EMU. To ensure the stable and reliable installation of the electrical components in the external control box of the air conditioner cabinet, a new fixing bracket 102 is required; moreover, to prevent passengers from contacting the electrical components and ensure the safety and aesthetics of the structure, a control box housing 104 needs to be added outside the fixing bracket 102 for protection.
[0030] In the embodiment of the present application, by adding an external control box 1 above the luggage rack 3 in the passenger cabin of the EMU, the installation and protection of the electrical components are realized. For details, see Figure 1 。
[0031] Refer to Figure 1 and Figure 2 , in the embodiment of the present application, a notch is opened at the side roof panel 2 above the luggage rack 3 in the passenger cabin of the EMU, and the body bent beam 4 inside the notch is used as the fixing position of the external control box 1.
[0032] Refer to Figure 2 and Figure 3 , a slide rail 101 with a chute is added between the fixing bracket 102 of the external control box 1 and the body bent beam 4. The slide rail 101 is installed on the body bent beam 4 by means of fastening with the first bolt 106 to ensure the firm and reliable installation of the external control box 1 during operation. The fixing bracket 102 is fixed on the slide rail 101 by a T-shaped bolt 107, and the position of the T-shaped bolt 107 on the slide rail 101 can be adjusted to make the installation of the fixing bracket 102 more flexible. See Figure 2 。
[0033] In the embodiment of the present application, the fixing bracket 102 is made by welding steel plates, and has relatively high structural strength.
[0034] Since the opening size of the notch provided on the side roof panel 2 should not be too large, and there are many electrical components to be installed on the fixing bracket 102, the installation and disassembly space of the fixing bracket 102 is small; therefore, round holes 1021 are opened in the middle and on both sides of the fixing bracket 102, which not only facilitates installation and disassembly but also realizes the lightweight of the fixing bracket 102. See Figure 3 。
[0035] The installation of the electrical components adopts a modular design. The electrical components are assembled onto the control board to form an air conditioner control panel 103. The control board of the air conditioner control panel 103 is fixed to the outer end face of the fixing bracket 102 by the second bolt 108 to ensure firm and reliable installation. See Figure 3 。
[0036] In the embodiments of the present application, for the specific control principle and circuit mechanism of the electrical components of the air conditioner control panel 103 to implement the manual control function, reference can be made to the prior art.
[0037] The air conditioner control panel 103 can be pre-assembled on the workbench, making the installation, maintenance, and disassembly of the electrical components more convenient and significantly reducing the working hours.
[0038] The control box body 104 is fixed on both sides of the fixed bracket 102 through the third bolt 109, the fourth bolt 110, and the adjustment gasket 111.
[0039] Refer to Figure 1 , the edge of the control box body 104 is in close contact with the side top plate 2, and a seal is formed between the control box body 104 and the side top plate 2 through the sealing strip 105, which not only plays a protective role for the air conditioner control panel 103 but also has aesthetic properties.
[0040] In the embodiments of the present application, by adding an external control box 1 to the EMU, it can ensure the installation of the manual refrigeration control panel in the case of insufficient space in the air conditioner control cabinet, adding a manual refrigeration function to the vehicle. This can avoid affecting the physical health and riding comfort of passengers when the air conditioner digital controller fails.
[0041] It should be noted that the embodiments in this specification are all described in a progressive manner. Each embodiment focuses on the differences from other embodiments. For the same or similar parts among the embodiments, reference can be made to each other.
