Description
The present invention relates to a waterproof structure of a vehicle control unit case of a heavy equipment vehicle, and more particularly,
In order to solve the problem of difficulty in assembling the sealing member and deterioration of the waterproof performance of the vehicle control unit case of the conventional heavy duty vehicle in which a sealing structure is formed between the top case and the bottom case to form a waterproof structure, And a sealing member that covers the entire side surface portion, thereby achieving a waterproof structure of the vehicle control unit of the heavy equipment vehicle only by assembling the top case.
Further, at least one perforation is further formed in the top case, the elastic pin is inserted into the perforation of the top case, and the volume of the top case is expanded by a predetermined interval by the elastic fin, And a technique for increasing waterproof performance.
Generally, a driver's seat of a heavy equipment such as a forklift, a bulldozer, a crane, etc. is provided with a display module for informing various conditions of a hydraulic device, a motor, etc. according to general conditions such as heavy fuel, electricity, (VECU, VEhicle Control Unit) for controlling the air conditioner, the wind direction, the automatic switching, the washer, the defrosting, the menu selection, the cancellation, and the sound control for the operation of the special equipment.
The vehicle control device is usually housed in a box-shaped case and disposed in a heavy equipment for protection from an external environment. However, in general, the heavy equipment vehicle may have irregular fluctuations in its use environment. In this case, there is a possibility that the water or other liquid flow used by the driver may be poured by the swing of the driver's seat, There is a possibility that it may cause a large damage if it is introduced into the apparatus.
In addition, heavy-duty vehicles generally have a structure that is less likely to be protected from the outside environment than a general passenger vehicle. For example, heavy-duty vehicles continue to operate at outdoor construction sites, such as construction sites, and are frequently parked at construction sites for a long time after exposure.
However, since the driver's seat of a heavy-duty vehicle is designed to be relatively more open than a general vehicle, the open environment of such a heavy-duty vehicle tends to easily expose an internal device of the heavy-duty vehicle to the external environment. Also in this case, when water such as rainwater flows in from the outside as in the case of rain, if the inflow water is introduced into the case of the vehicle control unit, there is a problem that the vehicle control unit may fail.
Therefore, the vehicle control unit case necessarily requires a waterproof structure to manufacture the vehicle control unit case.
FIG. 1 is an exploded perspective view of a conventional vehicle control unit case, and FIG. 2 is a cross-sectional view simply showing a waterproof structure of the conventional vehicle control unit case of FIG. 3 is a perspective view showing the upper surface of the bottom case of the conventional vehicle control unit case of FIG. 2 in detail.
As shown, the conventional vehicle control unit case includes a top case, a bottom case, and a sealing member.
At this time, the vehicle control unit is mounted inside the bottom case, and the top case covers the top surface of the bottom case and is fastened to each other, so that the conventional vehicle control unit case is assembled.
However, as shown in FIGS. 2 and 3, the sealing member inserted into the fastening surface of the top case and the bottom case to form the waterproof structure must be inserted in the slightly narrowed fastening surface, thereby causing difficulty in assembling There was a problem.
In order to prevent this, as shown in FIG. 3, a groove for receiving the sealing member is formed on the upper surface of the bottom case. However, the sealing member mounted in the groove is not shown in FIG. As a result, the elastic force provided by the sealing member can be largely lowered by the portion introduced into the inside of the groove, thereby increasing the possibility that the liquid flows into the gap between the top case and the bottom case .
The present invention has been made to solve the above problems,
In order to solve the problem of difficulty in assembling the sealing member and deterioration of the waterproof performance of the vehicle control unit case of the conventional heavy duty vehicle in which the sealing member is inserted between the top case and the bottom case constituting the vehicle control unit case to form the waterproof structure And a sealing member that covers the edge portion and the entire side surface portion of the top case, so that the waterproof structure of the vehicle control unit of the heavy equipment vehicle can be easily achieved simply by assembling the top case.
Further, according to the present invention, the at least one perforation is further formed in the top case, the elastic pin is inserted into the perforation of the top case, and the volume of the top case is expanded by a predetermined interval, So that the waterproof performance of the waterproof structure can be increased even after the first top case is assembled.
According to an aspect of the present invention,
A waterproof structure of a vehicle control unit case of a heavy equipment vehicle, the waterproof structure of a vehicle control unit case of a heavy equipment vehicle, comprising: a bottom case formed in a box shape having an open upper portion, the bottom case forming at least one exposed portion such that output ends of the vehicle control unit are exposed; A top case formed in a flat plate shape and coupled to an opened top end of the bottom case to cover an upper portion of the bottom case; And a sealing member made of an elastic material surrounding the edge of the top case, wherein when the top case and the bottom case are coupled, the sealing member is compressed between the top case and the bottom case to form a waterproof structure .
The bottom case is formed with an outer wall protruding upward along the upper edge thereof. The width of the top case is smaller than an inner wall width of the bottom case and larger than an inner width of the bottom case .
The sealing member may be formed along a side edge of the top case, and may cover the top, side, and bottom surfaces of the entire edge of the top case.
Further, the top case may be formed with at least one perforation formed by perforating in the vertical direction.
The at least one or more perforations are radially arranged with respect to a central portion of the top case.
Finally, it is preferable to further include at least one elastic pin made of an elastic material and inserted into the at least one perforation, wherein the elastic fin has a diameter larger than an inner diameter of the at least one perforation .
The present invention provides the following characteristic advantages through the above-described configuration.
1) By providing the sealing member that covers the edge portion and the entire side surface portion of the top case constituting the vehicle control unit case, the waterproof structure of the vehicle control unit of the heavy equipment vehicle can be easily achieved simply by assembling the top case And a sealing member is inserted between the top case and the bottom case constituting the vehicle control unit case to form a waterproof structure. In the conventional vehicle control unit case of the heavy duty vehicle, And the like.
2) At least one perforation is formed in the top case, and the elastic pin is inserted into the perforation of the top case, so that the volume of the top case is expanded by a predetermined interval by the elastic pin, The waterproof performance of the waterproof structure can be increased even after the assembly.
