Description

Technical Field

[0001] An exemplary embodiment of the present disclosure relates to a mounting apparatus for an upper module of a vehicle. Background Art

[0002] like Figure 1 As shown, a utility vehicle (hereinafter, referred to as a "vehicle") including a truck can be used for various purposes by replacing an upper module 111 and mounting it to an underbody 112 of the vehicle instead of using a loading platform.

[0003] The upper module 111 may be a fuel tank, a camping module, or a box-type loading platform. For example, a fuel tank is mounted on the lower body 112 and the vehicle can be used as a fuel tanker, or a camping module is mounted on the lower body 112 and the vehicle can be used as a camper. Alternatively, when a box-type loading platform is applied to the upper module 111, the empty loading platform is separated from the lower body 112 of the vehicle, the cargo is pre-loaded in the loading platform, and then the loading platform loaded with the cargo is mounted on the lower body 112 of the vehicle, so that in the field of cargo logistics such as door-to-door delivery services, the time required for loading cargo can be reduced.

[0004] To install the upper module 111 , mounting brackets 121 and 122 are provided on the upper module 111 and the lower body 112 , respectively, and the mounting brackets 121 and 122 are fastened to the lower body 112 at multiple points using fastening bolts 131 and fastening nuts 132 , thereby mounting the upper module 111 on the lower body 112 .

[0005] However, when the upper module 111 is installed using the fastening bolts 131 and the fastening nuts 132, the attachment and detachment work of the upper module 111 is not easy. When installing a new upper module 111, it is necessary to release the fastening bolts 131 and the fastening nuts 132, remove the previously installed loading platform, adjust the position of the new upper module 111, and tighten the fastening bolts 131 and the fastening nuts 132 again to install the upper module 111 on the lower body 112.

[0006] However, since the release and reconnection of the fastening bolts 131 and the fastening nuts 132 are repeated at a plurality of points, a lot of time is required, and when the new upper module 111 is installed, it is not easy to align the position of the new upper module 111 .

[0030] Hereinafter, a mounting unit of an upper module for a vehicle according to an embodiment of the present disclosure will be described in detail with reference to the accompanying drawings.

[0031] According to an embodiment of the present disclosure, the mounting unit 30 for the upper module of a vehicle may include: a base 31, mounted on the lower body 12 of the vehicle; a main rod 33, rotatably arranged on the base 31 and having a head 33a, which can pass through the mounting bracket 21 mounted on the upper module 11 of the vehicle according to the rotation of the main rod and can be clamped and fixed to the mounting bracket 21; and an operating handle 36, having an end portion connected to the main rod 33 and configured to rotate the main rod 33 to fix the head 33a to the mounting bracket 21.

[0032] The base 31 may be fastened to the lower body 12 of the vehicle. The base 31 may include an upper flange 31a formed to extend from an upper end portion in a direction parallel to the ground, and a lower flange 31c formed to extend from a lower end portion in a direction parallel to the ground. A mounting hole 31b and a through hole 31d through which the main rod 33 passes may be formed in the upper flange 31a and the lower flange 31c, respectively. The mounting hole 31b may be formed in the form of a long hole.

[0033] The cover 32 may be fastened to the outside of the base 31. The cover 32 may be formed in a curved shape to form a space for accommodating the main rod 33, and both end portions of the cover 32 are fastened to the base 31 by bolts (not shown).

[0034] The main lever 33 may be rotatably provided in the base 31. According to the rotation of the main lever 33, the main lever 33 may lock or unlock the mounting bracket 21 formed on the upper module 11. In a state where the main lever 33 unlocks the mounting bracket 21, the previously mounted upper module 11 may be detached and a new upper module 11 may be mounted. In a state where the main lever 33 locks the mounting bracket 21, the newly mounted upper module 11 may remain in a state of being firmly mounted on the vehicle.

[0035] The head 33a may be formed on the top of the main rod 33. According to the rotation of the main rod 33, the head 33a may pass through or may be stuck in the fixing hole 21a formed in the mounting bracket 21. The fixing hole 21a may be formed in the form of a long hole, and the cross section of the head 33a may be formed in a shape corresponding to the fixing hole 21a. Therefore, according to the arrangement state of the head 33a and the fixing hole 21a, the upper module 11 may be locked or unlocked relative to the lower vehicle body 12.

[0036] That is, when the head 33a is aligned with the fixing hole 21a in the same direction as the direction in which the length of the fixing hole 21a is longer, the upper module 11 can be in an unlocked state relative to the lower body 12, and when the head 33a is aligned with the fixing hole 21a in different directions, the upper module 11 can be in a locked state relative to the lower body 12.

[0037] The head portion 33a may be formed to have a cross-sectional area that narrows from the bottom to the top to be easily inserted into the fixing hole 21a. In addition, the cross-sectional area of ​​the head portion 33a may be formed to be slightly smaller than the cross-sectional area of ​​the fixing hole 21a.

[0038] An operating handle 36 may be fastened to a lower end portion of the main rod 33 .

[0039] The operating handle 36 may include a fastening portion 36 a coupled to the main rod 33 , and a handle 36 b extending from the fastening portion 36 a and held and operated by a user.

[0040] The fastening portion 36 a may be formed in a ring shape in which a fastening hole 36 c is formed, into which a lower end portion of the main rod 33 may be inserted, and thus the main rod 33 and the operating handle 36 may be coupled.

[0041] In particular, when the operating handle 36 rotates, in order to prevent the operating handle 36 from sliding with the main rod 33, a portion of the periphery of the lower end portion of the main rod 33 may be cut to form a flat first coupling surface 33c, and corresponding to the flat first coupling surface 33c, a portion of the fastening hole 36c may be formed as a flat second coupling surface 36e. Since the lower end portion of the main rod 33 and the fastening portion 36a are in surface contact with each other through the first coupling surface 33c and the second coupling surface 36e, sliding may not occur between the operating handle 36 and the main rod 33.

[0042] The handle 36 b may be formed to extend in a horizontal direction from the outer peripheral surface of the fastening portion 36 a . A user may rotate the main rod 33 by holding the handle 36 b and rotating the operating handle 36 .

[0043] The fastening protrusion 36d may be formed on the upper surface of the fastening portion 36a. The fastening protrusion 36d may be formed to protrude upward by a predetermined height h1 on a predetermined section of the upper surface of the fastening portion 36a. The fastening protrusion 36d may be caught on the protrusion 37b of the plate 37 to move the operating handle 36 and the main rod 33 downward.

[0044] The damper 34 may be assembled to the main rod 33. The damper 34 may be arranged to contact the bottom surface of the upper flange 31a of the base 31. Specifically, in the damper 34, an extension 34a is formed to extend upward. The extension 34a is formed at the main rod 33 on the damper 34 at intervals of 180 degrees so that the main rod 33 is located at a portion passing through the mounting hole 31b. In the mounting hole 31b, the extension 34a may be inserted between the main rod 33 and the mounting hole 31b.

[0045] The extension 34a can be expanded outward by the rotation of the main rod 33. Since a cam portion 33b protruding from a portion of the periphery below the head 33a is formed on the main rod 33, the cam portion 33b can press the extension 34a outward when the main rod 33 rotates. The cam portion 33b can be formed to press the extension 34a in a state where the main rod 33 restricts the upper module 11.

[0046] That is, in a state where the main rod 33 does not restrict the upper module 11, the cam portion 33b may not press the extension portion 34a, and a gap C may be formed between the mounting hole 31b and the extension portion 34a. However, when the main rod 33 rotates to restrict the upper module 11, the cam portion 33b may press the extension portion 34a outward so that the gap C disappears. Because the extension portion 34a is located between the mounting hole 31b and the cam portion 33b, the movement of the main rod 33 in a direction parallel to the ground can be suppressed.

[0047] The spring 35 may be assembled to the outer periphery of the main rod 33. The upper end portion of the spring 35 may be supported on the bottom surface of the damper 34, and the lower end portion of the spring 35 may be supported on the gasket 35a, so that the spring 35 elastically supports the damper 34 and the main rod 33 upward. The gasket 35a may be inserted into the through hole 31d of the lower flange 31c.

[0048] The plate 37 may be fastened to the bottom surface of the lower flange 31c. A through hole 37a may be formed in the plate 37 so that the main rod 33 passes through the through hole 37a. The protrusion 37b may be formed to protrude downward from a portion of the plate 37 by a predetermined height h2.

[0049] The protrusion 37b may contact the fastening protrusion 36d according to the rotation of the operating handle 36. Due to the rotation of the operating handle 36, the fastening protrusion 36d contacts the protrusion 37b, so the operating handle 36 may move downward by a predetermined height. When the height h1 of the fastening protrusion 36d is the same as the height h2 of the protrusion 37b, the operating handle 36 may move downward by a height equal to the height. Meanwhile, when the height h1 of the fastening protrusion 36d is different from the height h2 of the protrusion 37b, the operating handle 36 may move downward by a lower height of the two heights.

[0050] The cap nut 38 may be fastened to the bottom surface of the plate 37. The lower end portion of the main rod 33 and the operating handle 36 may be fastened within the cap nut 38. The cap nut 38 may be fastened to the lower end portion of the main rod 33. The cap nut 38 may restrict the lower end portion of the main rod 33 to prevent the main rod 33 from being pulled upward.

[0051] An operating state of the mounting unit 30 for the upper module of the vehicle having the above-described configuration according to the embodiment of the present disclosure will be described below.

[0052] Figures 4 to 6D A process of installing the upper module using the installation unit 30 for the upper module 11 is shown.

[0053] The mounting units 30 for the upper module may be provided at a plurality of points of the lower vehicle body 12. Corresponding to the mounting units 30, the mounting brackets 21 may be provided on the lower surface of the upper module 11.

[0054] In order to mount the upper module 11 on the lower body 12 of the vehicle, the upper module 11 can be aligned so that the mounting bracket 21 is located above the mounting unit 30 for the upper module (see FIG. Figure 4 ).

[0055] When the upper module 11 moves downward in a state where the upper module 11 is aligned with the lower vehicle body 12, the head 33a can be inserted into the fixing hole 21a of the mounting bracket 21. In the unlocked state, because the fixing hole 21a and the head 33a are aligned in the same direction, the head 33a can pass through the fixing hole 21a. When the upper module 11 continues to move downward, the lower surface of the mounting bracket 21 can be positioned on the upper surface of the base 31. In this state, the head 33a can pass through the fixing hole 21a, and the damper 34 can be positioned in the fixing hole 21a (see FIG. 2 ). Figure 5A and Figure 5B ).

[0056] In this state, since the head 33a is aligned with the fixing hole 21a in the same direction, the mounting unit 30 for the upper module may be in an unlocked state, so that the upper module 11 may not be fixed to the lower vehicle body 12 (see FIG. 1 ). Figure 5C In addition, because the cam portion 33b is in a state where the extension portion 34a is not pressed, a gap C may exist between the extension portion 34a and the fixing hole 21a, so that the upper module 11 can move relative to the lower body 12 within a predetermined distance (see Figure 5D ).

[0057] Next, if Figure 5C As shown in , in a state where the upper module 11 is positioned on the base 31 , the operating handle 36 may be rotated by a predetermined angle to lock the upper module 11 relative to the lower vehicle body 12 .

[0058] That is, when the operating handle 36 is rotated about 90 degrees in the clockwise direction, the main rod 33 can rotate, and the head 33a and the fixing hole 21a can be aligned in different directions, for example, at right angles, so that the head 33a is stuck on the fixing hole 21a and no longer moves downward (see FIG. Figure 6C In this way, the head 33 a can limit the upward movement of the mounting bracket 21 , so that the upper module 11 is locked relative to the lower vehicle body 12 .

[0059] In particular, when the operating handle 36 rotates, because the fastening protrusion 36d contacts the bottom surface of the protrusion 37b, the operating handle 36 can move downward by a height equal to the predetermined height h2. When the operating handle 36 rotates, the fastening protrusion 36d can rotate in a state of contacting the protrusion 37b, and thus the operating handle 36 and the main rod 33 can move downward. Until the operating handle 36 rotates so that the lower end portion of the main rod 33 can be located at L0 (see Figure 5B and Figure 6B ), and when the operating handle 36 is rotated, the main rod 33 can move downward so that the lower end portion of the main rod 33 is located at L1 (see Figure 6B ).

[0060] Due to the downward movement of the operating handle 36 , the main rod 33 may also move downward, and the head 33 a may press the mounting bracket 21 downward, thereby preventing a gap in the vertical direction from being generated when the upper module 11 is installed.

[0061] In addition, because the cam portion 33b squeezes the extension portion 34a outward due to the rotation of the main rod 33, the gap C between the extension portion 34a and the fixing hole 21a can disappear, and when the upper module 11 is installed on the lower body 12 and the extension portion 34a squeezes the inner surface of the fixing hole 21a, the generation of a gap in the horizontal direction can be prevented.

[0062] Meanwhile, the process of separating the upper module 11 can be performed in the reverse direction of the process of installing the upper module 11. That is, the user can move the operating handle 36 in the following manner: Figure 6C The main rod 33 is rotated in the counterclockwise direction as shown in FIG. 1 to rotate the main rod 33 so that the head 33a and the fixing hole 21a of the mounting bracket 21 are aligned in the same direction. When the head 33a and the fixing hole 21a are aligned in the same direction (see FIG. 1 ), the main rod 33 rotates in the counterclockwise direction as shown in FIG. Figure 5C ), the head 33a can pass through the fixing hole 21a, and thus the upper module 11 and the lower vehicle body 12 can be unlocked, that is, can be in a separable state. In this state, when the upper module 11 is lifted from the lower vehicle body 12, the upper module 11 can be separated from the vehicle.

[0063] As described above, by using the mounting unit 30 for the upper module according to the embodiment of the present disclosure, various types of upper modules 11 can be easily mounted on or removed from the lower body of the vehicle. Therefore, upper modules 11 of different shapes can be alternately mounted on the vehicle and used on the vehicle. Alternatively, by using a method of removing an empty loading platform and installing a loading platform pre-loaded with goods, the time required for loading goods at a distribution center can be reduced.

[0064] According to the mounting unit of the upper module for a vehicle of the embodiment of the present disclosure, the mounting unit has the above configuration, and in a state where the upper module is stationary on the upper portion of the lower body of the vehicle, the upper module can be securely mounted on the vehicle by simply manipulating the operating handle.

[0065] Therefore, various types of upper modules can be easily mounted on or removed from the lower body of the vehicle.

[0066] Furthermore, when the operating handle is manipulated, the main rod may move downward to press the mounting bracket on the upper module downward, so that the combining force between the mounting bracket and the base may be increased.

[0067] Although the embodiments of the present disclosure have been described with reference to the accompanying drawings, it is obvious to those skilled in the art that various changes and modifications may be made without departing from the spirit and scope of the present disclosure, and are not limited to the exemplary embodiments disclosed herein. Therefore, it should be noted that such replacement or modification falls within the claims of the present disclosure, and the scope of the present disclosure should be interpreted based on the appended claims.
