Abstract

The present invention relates to an air conditioning control PCB assembly structure for a hydrogen bus, wherein a coupling part is formed on the inner side of a housing to support the lower part of a main PCB, and fixing hooks are formed on both sides of the housing to securely connect the main PCB connected to the coupling part to the inside of the housing. This eliminates the need to connect a PCB holder between the housing and the panel to secure the main PCB and the front PCB as in the conventional method, thereby improving assembly and increasing the coupling strength. It also reduces the assembly process to facilitate the assembly of the front PCB and the main PCB, and reduces manufacturing costs because a separate PCB holder is not required as in the conventional method. Furthermore, a through hole is formed in the central part of the main PCB, and a pressure fixing part is formed protruding from the bottom surface of the housing to secure the lower part of the front PCB connected to the inside of the panel by pressing through the through hole, thereby enabling the front PCB to be securely fixed inside the panel.

Description

Air conditioning control PCB assembly structure for hydrogen bus The present invention relates to an air conditioning control PCB assembly structure for a hydrogen bus, and more specifically, to an air conditioning control PCB assembly structure for a hydrogen bus configured such that, by forming a coupling part that supports the lower part of a main PCB on the inner side of a housing and forming fixing hooks on both sides of the housing to securely connect the main PCB connected to the coupling part inside the housing, a PCB holder that fixes the main PCB and the front PCB as in the prior art is not required to be connected between the housing and the panel, thereby improving assembly efficiency and increasing coupling strength, reducing the assembly process to facilitate assembly of the front PCB and the main PCB, and reducing manufacturing costs because a separate PCB holder as in the prior art is not required. Generally, a hydrogen bus is a system that produces electrical energy by reacting hydrogen stored in a high-pressure storage container with oxygen via a fuel cell, and allows the generated electrical energy to directly power an electric motor or be stored in a battery to be used as power again later. An air conditioning system was installed in such a hydrogen bus, and a control device for turning the air conditioning system on and off was installed in the vehicle to control the temperature and humidity inside the vehicle. Figure 5 illustrates a conventional air conditioning control device for a hydrogen bus. A conventional air conditioning control device for a hydrogen bus comprises a panel (100) and a housing (110), a front PCB (120) coupled to the interior of the panel (100), a main PCB (130) coupled to the interior of the housing (110), and a PCB holder (140) coupled to be positioned between the front PCB (120) and the main PCB (130) to fix the front PCB (120) and the main PCB (130) while simultaneously fixing the front PCB (120) and the main PCB (130) respectively. Therefore, when the panel (100) and the housing (110) are combined, the front PCB (120) is fixedly coupled to the inside of the panel (100) by the PCB holder (140), and the main PCB (130) is fixedly coupled to the inside of the housing (110). However, the problem with the conventional air conditioning control device for hydrogen buses is that by combining the front PCB (120) and the main PCB (130) using a PCB holder (140), it is not easy to combine the front PCB (120) and the main PCB (130) into the interior of the panel (100) and the housing (110), respectively, and assembly is not easy. In addition, since the front PCB (120) and main PCB (130), which are respectively coupled inside the panel (100) and housing (110), must be fixed using a PCB holder, a problem has arisen in that the manufacturing cost of the air conditioning control device increases.
