Specifically, the protrusion insertion hole 25 may be formed through the outer part 24 of the side member 21 , and the protrusion insertion hole 131d may be formed in the outer surface support part 131a of the outer member 130 . . The insertion protrusion 153 may be formed at a position corresponding to the protrusion insertion hole 25 and the protrusion insertion hole 131d.

When the holder body 151 is rotated in the downward direction, the holder body 151 is rotated in the first direction by the elastic force of the first elastic member 161 pulling the rod member 140, and the insertion protrusion 153 is a protrusion. It is inserted into the insertion hole 25 and the projection insertion hole (131d). In addition, the holder body 151 may bring the outer member 130 into close contact with the side member 21 by the elastic force of the first elastic member 161 .

Meanwhile, a process of assembling the side member 21 using the vehicle mounting assembly 100 according to an embodiment of the present invention will be described below with reference to FIGS. 8 to 14 .

First, referring to FIG. 8 , in the initial state before the side member 21 is assembled, the rod member 140 and the inner member 120 are moved in the first direction, so the roller member 171 is formed through the roller guide hole ( 125) and at the end of the guide slot 113 in the first direction. At this time, the outer member 130 and the holder member 150 are rotated upward.

In this state, the side member 21 may enter in the A direction. At this time, the inner member 120 can be rotated by the inserted side member 21 (refer to the dotted line in FIG. 8 ), and the rotation of the inner member 120 is prevented by the lower end of the side wall 117 of the mounting member 110 It is limited and can be positioned in place.

Next, referring to FIGS. 9 and 10, when the holder member 150 is pulled in the second direction (refer to the arrow direction) by the operator, the rod member 140 moves while the first elastic member 161 is tensioned, The inner member 120 is moved in the second direction by the roller member 171 .

At this time, while the outer pressing part 126 of the inner member 120 presses the upper straight part 133 of the outer member 130, the outer member 130 may be rotated around the bearing fixing part 134 ( see Fig. 10). In this case, the second elastic member 162 may be rotated.

11 and 12 , when the holder member 150 is further pulled in the second direction, the outer member 130 is further rotated so that the bearing fixing part 134 moves in the first direction of the outer sliding groove 127 . It can move to the end, and the outer member 130 and the inner member 120 are in close contact. Accordingly, the inner member 120 having the outer member 130 may be in close contact with the inserted side member 21 .

When the holder member 150 is rotated around the hinge member 173 as shown in FIG. 13 , the insertion protrusion 153 is positioned at a position corresponding to the protrusion insertion hole 131d and the protrusion insertion groove.

Thereafter, as shown in FIG. 14 , the insertion protrusion 153 may be inserted into the protrusion insertion groove and the protrusion insertion hole 131d while the rod member 140 moves in the first direction by the tensile force of the first elastic member 161 . . And even after being inserted, the rod member 140 is pulled by the elastic restoring force of the first elastic member 161 and the holder member 150 pulls the outer member 130 to make the outer member 130 more closely attached to the side member. can

Through this process, the side member 21 is fixed to the vehicle mounting assembly 100 , whereby the side member 21 and the vehicle body side seal part 11 may be coupled to each other.

After that, when the body part 10 and the chassis frame part 20 are separated for replacement of the body part 10, the above-described process is performed in the reverse order, so that the side member 21 is connected to the inner member 120 and the inner member 120. It can be separated between the outer members 130 .

That is, in the state in which the side member 21 is assembled (refer to FIG. 14), the holder member 150 is pulled in the first direction to remove the insertion protrusion 153 from the protrusion insertion hole 131d (refer to FIG. 13), the holder The member 150 may be rotated upward (see FIGS. 11 and 12 ). At this time, the rod member 140 may be moved in the first direction by the tensile force caused by the elastic restoring force of the first elastic member 161 .

As the rod member 140 moves in the first direction, the pressing force pressing the upper straight part 133 of the outer member 130 by the outer pressing part 126 is released, and at this time, the elastic restoring force of the second elastic member 162 is released. Thus, the outer member 130 may be rotated upward (refer to FIGS. 9 and 10). Accordingly, the side member 21 can be separated while being spaced apart between the inner member 120 and the outer member 130 .

In the vehicle mounting assembly according to an embodiment of the present invention, the outer member is provided to rotate in association with the movement of the inner member, so that the side seal part of the vehicle body and the side member can be easily combined or separated.

Accordingly, using an embodiment of the present invention, the body part can be easily replaced, and various body parts can be easily combined with the chassis frame without separate bolting, bonding, welding, etc. and can be separated.

Therefore, using the present invention, it is possible to easily replace various body parts in the side members especially when using multi-purpose mobility that requires replacement of body parts of various shapes and functions according to the purpose and use of the user.

As mentioned above, although specific embodiments of the present invention have been described above, the spirit and scope of the present invention are not limited to these specific embodiments, and those described in the claims by those of ordinary skill in the art to which the present invention pertains Various modifications and variations are possible without changing the gist of the present invention.
