Description

Technology Field

[0001] 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. Background Technology

[0003] 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.

[0004] 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.

[0005] Figure 5 illustrates a conventional air conditioning control device for a hydrogen bus.

[0006] 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.

[0007] 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).

[0008] 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.

[0009] 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. The problem to be solved

[0011] Accordingly, the present invention aims to provide an air conditioning control PCB assembly structure for a hydrogen bus configured to solve the above problems by forming a coupling part that supports the lower part of the main PCB on the inner side of the housing, and forming fixing hooks on both sides of the housing to securely secure the main PCB coupled to the coupling part inside the housing, thereby eliminating the need to connect a PCB holder that secures the main PCB and the front PCB between the housing and the panel as in the conventional method, thereby improving assemblyability and increasing coupling strength, reducing the assembly process to facilitate assembly of the front PCB and the main PCB, and reducing manufacturing costs by eliminating the need to use a separate PCB holder as in the conventional method. Additionally, 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 coupled inside the panel by pressing through the through hole and securing it, thereby enabling the front PCB to be firmly secured inside the panel. means of solving the problem

[0013] The present invention for achieving the above objective is,

[0014] An air conditioning control PCB assembly structure for a hydrogen bus comprising a panel and a housing, a front PCB coupled to the panel, and a main PCB coupled to the housing, wherein

[0015] A connecting part formed to protrude longitudinally in the center of the inner surface of the housing to support the lower part of the main PCB;

[0016] It is characterized by being configured with fixing hooks formed to protrude from both sides of the housing so as to press and fix the upper surface of the main PCB coupled to the coupling part; thereby increasing the coupling force of the main PCB coupled inside the housing, and improving assembly by coupling the housing and the panel while the main PCB is fixed by the coupling part and the fixing hooks. Effects of the invention

[0018] According to the present invention, a coupling portion is formed on the inner side of a housing to support the lower part of a main PCB, and a fixing hook is formed on both sides of the housing to securely connect the main PCB connected to the coupling portion to the inside of the housing. This eliminates the need to connect a PCB holder between the housing and the panel to fix the main PCB and the front PCB as in the conventional method. Consequently, assembly can be improved and the coupling strength increased, and the assembly process can be reduced to facilitate the assembly of the front PCB and the main PCB. Furthermore, since a separate PCB holder is not required as in the conventional method, the effect of reducing manufacturing costs can be expected.

[0019] In addition, 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 fix the lower part of the front PCB coupled inside the panel by penetrating through the through hole, thereby allowing the effect of firmly fixing the front PCB inside the panel to be expected.

[0022] Hereinafter, a preferred embodiment of the present invention will be described using the attached FIGS. 1 to 4.

[0023] According to the above drawings, the present invention is,

[0024] An air conditioning control PCB assembly structure for a hydrogen bus comprising a panel (10) and a housing (20), a front PCB (50) coupled to the panel (10), and a main PCB (60) coupled to the housing (20),

[0025] A connecting part (30) formed to protrude longitudinally in the center of the inner surface of the housing (20) and supporting the lower part of the main PCB (60);

[0026] The device is characterized by being configured with fixing hooks (40) formed to protrude from both sides of the housing (20) so as to press and fix the upper surface of the main PCB (60) connected to the connecting part (30), thereby increasing the bonding force of the main PCB (60) connected inside the housing (20), and allowing the main PCB (60) to be fixed by the connecting part (30) and the fixing hooks (40) to improve assembly by connecting the housing (20) and the panel (10).

[0027] And, fixing hooks (40) are formed on both sides of the housing (20) symmetrically around the connecting part (30), and

[0028] The above fixed hook (40) is,

[0029] A tension member (41) formed such that its lower end is connected to the inner surface of the housing (20);

[0030] It is composed of a fixing projection (42) formed to protrude from the top of the tension part (41) and presses and fixes the upper surface of the main PCB (60) coupled to the upper surface of the coupling part (30);

[0031] It is characterized by further forming a guide surface (43) on the upper surface of the fixing projection (42) at a downward slope to guide the main PCB (60) to the coupling part (30).

[0032] In addition, the outer surface of the main PCB (60) is fitted and coupled with a fitting groove (31) formed on the upper surface of the coupling part (30) in a stepped manner.

[0033] And a support member (11) is formed protrudingly in the center of the inner surface of the panel (10) so as to support the upper surface of the front PCB (50), and

[0034] A through hole (70) is formed in the center of the main PCB (60),

[0035] It is characterized by forming a pressure fixing part (80) protruding from the inner bottom surface of the main PCB (60) corresponding to the through hole (70) so as to fix the lower center of the front PCB (50) which is supported by the support part (11) while penetrating the through hole (70).

[0037] FIG. 1 is an exploded perspective view of an air conditioning control PCB assembly structure for a hydrogen bus according to the present invention, FIG. 2 is a cross-sectional perspective view of an air conditioning control PCB assembly structure for a hydrogen bus according to the present invention, and FIG. 3 and FIG. 4 are cross-sectional views of an air conditioning control PCB assembly structure for a hydrogen bus according to the present invention.

[0039] The present invention is composed of a panel (10) and a housing (20) that are combined by one touch as shown in FIG. 1, and a front PCB (50) and a main PCB (60) that are respectively combined to the panel (10) and the housing (20).

[0040] A plurality of coupling holes (12) are formed in the lower part of the panel (10), and a plurality of coupling protrusions (21) corresponding to the coupling holes (12) are formed in the lower part of the housing (20), so that the housing (20) is coupled to the inside of the panel (10) with a single touch using the coupling holes (12) and coupling protrusions (21).

[0041] In this way, a support member (11) is formed protruding in the longitudinal direction on the inner surface of the panel (10) to which the housing (20) is joined by one touch, and the front PCB (50) is joined by using the support member (11) so as to be spaced apart from the inner upper part of the panel (10).

[0042] A coupling part (30) is formed protrudingly on the upper surface of a housing (20) that is coupled to the interior of the panel (10), with a coupling groove (31) formed at a step. By using the coupling part (30), the main PCB (60) is coupled to the inner bottom surface of the housing (20) while being spaced apart from the main PCB (60). Since the outer surface of the main PCB (60) is coupled to the coupling groove (31), the main PCB (60) coupled to the interior of the housing (20) can be prevented from moving left or right.

[0043] A fixing hook (40) capable of fixing the main PCB (60) coupled to the coupling part (30) is formed on both sides of the housing (20), so that the upper surface of the main PCB (60) coupled to the coupling groove (31) of the coupling part (30) is pressed by the fixing projection (43) of the fixing hook (40) and coupled.

[0044] The above fixing hook (40) is formed to correspond to the coupling portion (30) formed on both sides of the center of the housing (20).

[0045] A through hole (70) is formed in the center of the main PCB (60) which is fixedly coupled inside the housing (20) using the above coupling part (30) and fixing hook (40), and a pressure fixing part (80) that penetrates the through hole (70) is formed to protrude from the inner bottom surface of the housing (20), so that the pressure fixing part (80) presses and fixes the central part of the front PCB (50) coupled inside the panel (10).

[0047] The preferred combined state of the present invention, configured in this manner, is described as follows.

[0048] First, the front PCB (50) is connected to the inside of the panel (10) so as to be in close contact with the bottom of the support member (11).

[0049] Then, the main PCB (60) is coupled into the interior of the housing (20) so that the outer surface of the main PCB (60) is fitted into the coupling groove (31) provided at the top of the coupling part (30).

[0050] As the main PCB (60) is coupled into the interior of the housing (20), the pressure fixing part (80) protruding from the inner bottom surface of the housing (20) penetrates through the through hole (70) provided in the main PCB (60) and enters into the interior of the housing (20).

[0051] The outer surface of the main PCB (60) entering the interior of the housing (20) comes into contact with the guide surface (43) provided on the fixing projection (42) constituting the fixing hook (40).

[0052] As the outer surface of the main PCB (60) comes into contact with the guide surface (43), the tension part (41) bends outward toward the housing (20), and the main PCB (60) passes through the fixing projection (42) and is coupled to the coupling groove (31) of the coupling part (30) by the bending tension part (41).

[0053] As the main PCB (60) is coupled to the coupling groove (31), the fixing projection (42) returns to its original state by the elastic force of the tension part (41), thereby pressing the upper surface of the main PCB (60) coupled to the upper surface of the coupling part (30) and being fixedly coupled inside the housing (20).

[0054] When the main PCB (60) is fixedly coupled to the housing (20) inside, the housing (20) is coupled as if being fitted into the interior of the panel (10), and the pressure fixing part (80) penetrating through the through hole (70) presses the lower central part of the front PCB (50) supported by the support part (11) of the panel (10), thereby fixingly coupling the front PCB (50) coupled as if being fitted into the panel (10) and the main PCB (60) coupled to the interior of the housing (20).
