[0025] In the following, the tool box for a cargo truck cargo compartment, which automatically lifts and opens and closes the upper lid according to the present invention, will be described in detail with reference to the drawings.

[0026] FIG. 1(a) shows a schematic diagram of a tool box in which the intermediate frame part (20) and the cover part (30) of the present invention are closed; FIG. 1(b) shows a schematic diagram of the rear of a tool box in which the cover part (30) of the present invention is open; FIG. 1(c) shows a schematic diagram of the front of a tool box in which the cover part (30) of the present invention is open; FIG. 1(d) shows a schematic diagram of a tool box in which the intermediate frame part (20) of the present invention is raised; and FIG. 1(e) shows a schematic diagram of a tool box in which the intermediate frame part (20) of the present invention is raised and the cover part (30) is open. As shown in FIG. 1, the intermediate frame part (20), which is located on the upper part of the main body part (10) having a space for loading objects inside, can be moved in an upward or downward direction, or the cover part (30) can be opened and closed by rotating.

[0027] The tool box for a cargo compartment of the present invention is primarily installed in the cargo compartment or the underside of the vehicle body to store and organize tools, parts, safety equipment, etc. This increases the space utilization of the cargo area and helps to quickly locate necessary tools. In addition, the tool box for a cargo compartment protects tools from external impacts and prevents theft. For example, regarding the storage of tools and parts, various tools such as hammers, wrenches, and screwdrivers, as well as parts such as bolts, nuts, and washers, are organized and stored; regarding the storage of safety equipment, safety equipment such as safety shoes, safety helmets, and safety vests are stored so that they can be quickly worn when needed; and regarding space utilization, the cargo space of the truck is used efficiently, and cargo and tools can be stored separately.

[0028] FIG. 2(a) shows a conceptual diagram of a tool box of the present invention, and FIG. 2(b) shows a conceptual diagram of a barrier part (60) located at the top of the tool box of the present invention. As shown in FIG. 2, a tool box for a cargo truck cargo compartment, which is an embodiment of the present invention, which automatically opens and closes by lifting the top lid, comprises: a main body part (10) having a space for loading items inside; an intermediate frame part (20) located at the top of the main body part (10) and moving in an upward or downward direction relative to the main body part (10); and a cover part (30) located at the top of the intermediate frame part (20), which opens and closes by rotating the y-axis as the axis of rotation, where the direction parallel to the length direction of the intermediate frame is defined as the y-axis, the direction parallel to the width direction of the intermediate frame is defined as the x-axis, and the direction perpendicular to one surface of the intermediate frame is defined as the z-axis.

[0029] The main body (10) of the present invention is provided with a space for storing items inside and is mainly made of steel plate, aluminum, or composite material. Steel plate has high strength and excellent durability but has the disadvantage of being heavy, aluminum is light and does not rust but may have relatively low strength, and composite material is a form that combines the two advantages and is desirable in terms of durability and strength.

[0030] The vertical movement of the intermediate frame part (20) and the cover part (30) provides convenience to the user. For example, when a user attempts to lift an item loaded in a tool box for a cargo truck, the intermediate frame part (20) and the cover part (30) connected thereto move upward so that the user can easily lift the item. Conversely, when a user loads an item into a tool box for a cargo truck, the intermediate frame part (20) and the cover part (30) connected thereto move downward so that the user can easily put the item down.

[0031] A barrier section (60) is provided on the upper part of the cover section (30), and the barrier section (60) is composed of a pipe selected from square, circular, and elliptical shapes with a hollow interior. The barrier section (60) includes a horizontal barrier section (61) formed parallel to one side of the cover section (30) and a plurality of vertical barrier sections (62) formed perpendicularly to the bottom of the horizontal barrier section (61) and one side of the cover section (30).

[0032] Therefore, when placing a load on the upper part of the cover section (30), if the load is secured to the upper part of the cover section (30) by using a securing means such as a strap to tie it to the horizontal barrier section (61) or the vertical barrier section (62), it has the advantage of stably securing the load to the upper part of the cover section (30).

[0033] Here, with respect to the upper surface area (S10) of the main body (10), the upper surface area (S20) of the intermediate frame part (20) and the upper surface area (S30) of the cover part (30) satisfy the following relationship 1, so that even if rainwater falls from above, the upper surface area (S20) of the intermediate frame part (20) and the upper surface area (S30) of the cover part (30) are larger than the upper surface area (S10) of the main body (10), so the rainwater does not seep into the main body (10) at the ends of the intermediate frame part (20) and the cover part (30) but falls to the ground.

[0034] (Relationship 1) S10 < S20 and S10 < S30

[0035] In addition, if a straight groove (not shown) with an incline is formed on the upper surface of the cover portion (30) and extends to the side of the cover portion (30), rainwater moves at a constant speed through the inclined groove from the upper part of the main body portion (10) and falls in an inclined direction rather than downward from the main body portion (10) due to the acceleration of the rainwater from the side of the cover portion (30), causing the rainwater to fall away from the main body portion (10). Therefore, even on rainy days, there is an effect of preventing rainwater from leaking into the boundary between the main body portion (10) and the intermediate frame portion (20) or the cover portion (30).

[0036] FIG. 3(a) shows a conceptual diagram of a tool box with a cargo load (35) of the present invention, and FIG. 3(b) shows a conceptual diagram of a rubber fixing part (70) of the present invention. As shown in FIG. 3, six rubber fixing parts (70) are provided on the lower surface of the main body (10) to cushion impact, and the rubber fixing part (70) is provided with a vibration-damping rubber (71) fixed to the lower surface of the main body (10), a seating pad (73) located below the vibration-damping rubber (71), and a lower support plate (72) located at the boundary between the vibration-damping rubber (71) and the seating pad (73), and a spring (71-1) is formed within the vibration-damping rubber (71). For example, six rubber fixing parts (70) on the lower surface of the main body (10) are provided with a first to third rubber fixing part adjacent to the front of the main body (10) and a fourth to sixth rubber fixing part adjacent to the rear of the main body (10). A first to third spring is provided inside the first to third rubber fixing parts, and a fourth to sixth spring is provided inside the fourth to sixth rubber fixing parts. The anti-vibration rubber (71) serves to cushion the impact applied when placing cargo (35) on the cover part (30) or loading items into the main body (10). Here, if a spring (71-1) is formed inside the anti-vibration rubber (71), the effect of shock absorption due to elasticity can be enhanced. The seating pad (73) is made of plastic so that the main body (10) can be placed more stably on the vehicle. The lower support plate (72) serves to fix the anti-vibration rubber (71) and the seating pad (73).

[0037] In addition, it is preferable to use springs with elastic moduli that are smaller than springs with elastic moduli that are smaller than springs with elastic moduli that are smaller than springs with elastic moduli that are installed inside springs with elastic moduli that are installed inside springs with elastic moduli that are smaller than springs with elastic moduli that are installed inside springs with elastic moduli that are smaller than springs with elastic moduli that are smaller than springs with elastic moduli that are smaller than springs with elastic moduli. This results in a greater rebound at the rear of the main body (10) than at the front when loading cargo (35), thereby providing a more stable effect for the user to hold and lower the cargo (35) from the front of the main body (10).

[0038] FIG. 4(a) shows a conceptual diagram of a tool box with the intermediate frame part (20) of the present invention raised, and FIG. 4(b) shows a conceptual diagram of a first pole part (42) used in the electric vertical movement lift part (40) of the present invention.

As shown in FIG. 4 and 5, the intermediate frame part (20) is raised and lowered by the electric vertical movement lift part (40) located on both inner sides of the main body part (10).

[0039] The device is provided with a right first receiving part (41-1) fixed to the inner surface of the main body (10), and a right first pole part (42-1) installed so as to be inserted into the right first receiving part (41-1), wherein the end of the right first pole part (42-1) is connected to the lower surface of the intermediate frame part (20). Additionally, the device is provided with a left first receiving part (41-2) fixed to the inner surface of the main body (10), and a left first pole part (42-2) installed so as to be inserted into the left first receiving part (41-2), wherein the end of the left first pole part (42-2) is connected to the lower surface of the intermediate frame part (20).

[0040] The above electric vertical movement lift unit (40) is raised and lowered by a controller (not shown) and is driven by electric energy supplied from a battery in the vehicle.

[0041] The first pole section (42) has the advantage of stably supporting the intermediate frame section (20) by means of the horizontal support section (42p), which is connected to one end of the vertical support section (42v). Here, the contact area between one side of the horizontal support section (42p) and the lower surface of the intermediate frame section (20) is considered and reflected during the design of the tool box, taking into account the weight of the intermediate frame section (20) and the cover section (30), as well as the weight limit placed on the cover section (30).

[0042] FIG. 6 shows a conceptual diagram of a tool box in which the intermediate frame portion (20) of the present invention is raised and the cover portion (30) is open. FIG. 7(a) shows a conceptual side view of a tool box in which the intermediate frame portion (20) and the cover portion (30) of the present invention are closed, and FIG. 6(b) shows a conceptual front view of a tool box in which the cover portion (30) of the present invention is rotated. As shown in FIG. 6 and 7, if the direction parallel to the length direction of the cover portion (30) is defined as the y-axis, the direction parallel to the width direction of the cover portion (30) is defined as the x-axis, and the direction perpendicular to one side of the cover portion (30) is defined as the z-axis, the cover portion (30) can be opened and closed by rotating the y-axis from 0 to 90 degrees with the y-axis as the rotation axis. The electric opening and closing lift portion (50) can be driven by an electrically connected motor, etc.

[0043] The above electric opening and closing lift is provided with a second receiving portion (51) connected to the lower surface of the cover portion (30), and a second pole portion (52) installed to be insertable into the interior of the second receiving portion (51) and connected to the upper surface of the intermediate frame portion (20). One end of the second receiving portion (51) is provided with a rotating portion (53) coupled to the lower surface of the cover portion (30) to control rotation in the direction of the y-axis rotation axis, and one end of the second pole portion (52) is provided with a rail portion (54) that moves parallel to the x-axis on the upper surface of the intermediate frame portion (20). Accordingly, one end of the second receiving portion (51) is rotated with the y-axis as the rotation axis direction at a position fixed to the lower surface of the cover portion (30), and one end of the second pole portion (52) moves within the rail portion (54), and when the cover portion (30) is to be closed, one end of the second pole portion (52) moves forward of the rail portion (54), and when the cover portion (30) is to be opened, one end of the second pole portion (52) moves backward of the rail portion (54).

[0044] In addition, if the electric vertical movement lift unit (40) located on both inner sides of the main body (10) fails to move the intermediate frame unit (20) up and down, the automatic device is released and the operator can manually open and close the cover unit (30) by holding the handle provided at one end.
