However, this is not intended to limit the present invention to the specific disclosed forms, and it should be understood that it includes all modifications, equivalents, and substitutions that fall within the spirit and scope of the invention.

[0046] Hereinafter, the features of the configuration of the rear camera connection system for a yard chassis according to the present invention can be understood through embodiments described in detail with reference to the attached drawings.

[0047] First, the present invention relates to a yard tractor (20) and a yard chassis (10) used to move and load a container (1) unloaded by a gantry crane at a container terminal to a container storage area (P). As shown in FIG. 1, the configuration and connection structure of the yard chassis (10) and the yard tractor (20) are already known general configurations, so a detailed description will be omitted.

[0048] In the present invention, as shown in FIGS. 2 and 3, a rear camera (40) is installed at the rear of the yard chassis (10), and a terminal housing (13) is provided at the front. By assembling the cable of the yard tractor (20) connected to the yard chassis (10) into the terminal housing (13), the rear situation can be identified through the navigation monitor (25) from the driver's seat, thereby preventing safety accidents and moving the yard chassis (10) to a more accurate position.

[0049] A yard chassis (10) has a container (1) loaded on the upper part of the chassis frame and a terminal housing (13) having a connector and a rear camera connection terminal on the front of the chassis frame. The terminal housing (13) has a sealed enclosure shape and has a circuit board inside, which is connected to the power, pneumatic, video cables, etc. of a yard tractor (20). The configuration of the connector, circuit board, etc. can be applied in various ways according to the requirements of a person skilled in the art, so it is not limited to a specific one.

[0050] The yard tractor (20) is a general operating device that is connected to the yard chassis (10) and has a cable assembled with a connector and a rear camera connection terminal to repeatedly transport containers unloaded from a gantry crane to a container storage area (P). It is assembled with a plurality of yard chassis (10) to transport the containers, and has a cable positioned at the rear easily connected to a terminal housing (13) to supply or receive power, pneumatic, and video data.

[0051] Accordingly, a navigation monitor (25) is installed on the dashboard of the yard tractor (20) to display images captured by the rear camera (40) when the yard tractor (20) moves in reverse. When the yard tractor (20) moves forward, location data regarding the entire area of ​​the container terminal and the loading location of the yard chassis (10) containing the container is transmitted and received with the Terminal Operating System (TOS) and displayed, thereby guiding the loading location and the movement path of the yard tractor to improve driving convenience.

[0052] And, the enclosure housing (30) installed at the rear of the yard chassis (10) is fixedly installed with a buffer (C1) on the chassis frame to offset vibrations and shocks caused by the operation of the yard tractor, so that the image captured by the rear camera is clearly displayed on the navigation monitor (25), and is configured so that the connection parts of the power and video lines connected to the terminal housing (13) and the rear camera (40) are not separated.

[0053] Here, the above-described housing (30) is configured such that a main housing (31) having a square housing shape has a "C" shaped camera installation part (35) formed by bending it at the rear so that a rear camera (40) can be assembled thereon, housing side plates (36) are assembled on both sides of the main housing (31) to shield the sides of the camera installation part (35), and a housing finishing plate (37) is assembled at the rear of the main housing (31) so that only the lens of the rear camera (40) is exposed to the outside.

[0054] Additionally, the above-mentioned housing (30) is formed by bending it so that the camera installation part (35) is open in the rearward direction, and thus the interior of the housing has a hollow state. Therefore, by filling the interior of the housing with a thermal insulation material (C2) that has thermal insulation and waterproofing functions, or by inserting a thermal insulation material (C2) formed to correspond to the internal shape of the housing, heat conduction to the rear camera (40) assembled in the camera installation part (35) can be prevented in advance even if the external temperature of the housing (30) changes, such as in summer and winter. This may also be included in the present invention.

[0055] In addition, an elastic anti-vibration member (C3) is provided between the inner wall surface in the upper, lower, and side directions of the camera installation part (35) and the rear camera (40), thereby preventing shocks and vibrations generated during the operation of the yard tractor (20) from being transmitted to the rear camera (40), and the rear camera (40) is configured to be firmly fixed to the initial set position in the enclosure housing (30) to capture stable images.

[0056] In addition, a lighting element (C4) is separately provided in the above-mentioned housing (30) or a lighting element (C4) is provided together with the rear camera (40), so that when the yard tractor (20) moves in reverse, the power of the lighting element (C4) is turned on and a warning message, color, etc. are displayed on the ground to inform surrounding workers of the direction of movement of the yard tractor (20), and even at night, the image captured through the rear camera (40) is clearly displayed on the navigation monitor (25), so that the driver can easily check the rear situation.

[0057] In addition, a plurality of detection sensors (S1) are installed on the rear side and rear of the chassis frame of the yard chassis (10), and the wires of the detection sensors are connected to the circuit board of the terminal housing so that the driver can identify the proximity of a worker or object in the rear blind spot on the navigation monitor (25) of the yard tractor (20).

[0058] In addition, the present invention may also include the ability to display a warning sound and a warning color according to proximity based on the sensing signal of the detection sensor (S1) on the navigation monitor, thereby enabling the driver to more clearly perceive the situation behind.

[0059] Here, the circuit board memory provided in the terminal housing (13) of the yard chassis (10) is provided in a non-volatile memory state in which the unique number of the yard chassis (10) is stored, so that the unique number is stored even when there is no power supply to the yard tractor (20), and when the power is connected to the yard tractor (20), the unique number of the yard chassis is displayed on the navigation monitor (25) so that the driver can easily check it, and the navigation communication unit transmits the operation and location data of the yard chassis to the Terminal Operating System (TOS) to update the work order.

[0060] As an embodiment of the present invention, as shown in FIG. 4, the main housing (31) is formed into a "C" shape in which the housing top plate (31a), the housing inner plate (31b), and the housing bottom plate (31c) are continuously bent, so that a camera installation part (35) is formed on the inside, and the housing top plate (31a) is formed to have a sunshade part (32) that is extended further in the horizontal length direction than the housing bottom plate (31c), so that rainwater or foreign matter can be prevented from entering in the direction of the camera installation part (35).

[0061] To this end, the sunshade portion (32) of the above-mentioned housing plate (31a) is formed such that the upper support surface (32a) has a downward slope angle of at least 5 to 15° in the outward direction, so that rainwater is guided along the upper support surface (32a) toward the rearward outward direction.

[0062] In addition, it is preferable that the lower support surface (32b) of the sunshade part (32) be formed to have an upward inclination angle of at least 10 to 30° in the outward direction so that the sunshade part (32) does not interfere with the shooting range of the rear camera (40) assembled to the camera installation part (35).

[0063] In addition, the lower support surface (32b) of the awning part (32) is configured to have at least one rainwater drop projection (32c) having a spire shape formed along the width length direction of the awning part (32), so that rainwater flowing from the front end of the awning part toward the lower support surface (32b) falls through the rainwater drop projection (32c), thereby preventing rainwater from flowing along the lower support surface (32b) and allowing the lens of the rear camera to always clearly capture the rear situation.

[0064] Here, the rainwater drop projection (32c) formed on the lower support surface (32b) may be shaped like a spire or have a concave groove, and attaching a separate spire projection may also be included in the present invention.

[0065] According to the present invention, a rear camera can be installed more easily at the rear of a yard chassis, and the rear camera can be safely protected against external impacts.

[0066] In addition, it prevents deformation of the enclosure housing in which the rear camera is assembled even in the event of a rear collision of the yard chassis, and by using the said enclosure housing to block rainwater ingress, it prevents the rear camera from malfunctioning and ensures rear visibility.

[0067] In addition, the unique number of the yard chassis and the video captured by the rear camera are displayed on the navigation monitor of the yard tractor to guide the yard tractor to the exact unloading location of the container yard, and the yard chassis is unloaded while recognizing surrounding objects, thereby preventing safety accidents in advance.

[0068] As described above, the embodiments explained are the most preferred examples of the present invention, but are not limited to the above embodiments, and it is obvious to those skilled in the art that various modifications are possible within the scope of the technical spirit of the present invention.
