FIG. 6 is a schematic diagram for explaining a configuration of a loading platform side bracket 36. 4 is a schematic diagram for explaining water passing through a gap G. FIG.

<Vehicle configuration>
A configuration of a vehicle having a cab and cargo bed connection structure according to an embodiment of the present invention will be described with reference to FIGS. 1 and 2.

  Drawing 1 is a mimetic diagram which looked at vehicle 1 concerning one embodiment from the side. FIG. 2 is a schematic diagram for explaining the internal configuration of the vehicle 1. In FIG. 2, the surrounding member 60 is omitted for convenience of explanation.

  Here, the vehicle 1 is a truck having a frame structure. As shown in FIGS. 1 and 2, the vehicle 1 includes a vehicle frame 10, a cab 20, a loading platform 30, a connecting portion 40, a hood member 50, and a surrounding member 60. The vehicle 1 is a vehicle in which an occupant can walk through between the cab 20 and the loading platform 30 via the connecting portion 40.

  The vehicle frame 10 is a skeleton that supports the vehicle 1. For example, the vehicle frame 10 includes a pair of side frames extending in the front-rear direction of the vehicle 1 (the X direction in FIG. 1), and a cross member provided between the pair of side frames. A drive source (for example, a motor) that generates power is attached to the front portion of the vehicle frame 10.

  The cab 20 is mounted on the vehicle frame 10 as shown in FIG. 1, and is located above a drive source (for example, a motor). Inside the cab 20 is formed a passenger compartment in which a passenger such as a driver sits. The roof 21 above the cab 20 is a high roof. As shown in FIG. 2, a cab opening 24 that is a rectangular opening is formed on the back surface 22 side of the cab 20. The opening of the cab opening 24 is also formed in the roof 21 so that an occupant can walk through.

  The loading platform 30 is mounted on the vehicle frame 10 and is located behind the cab 20. The loading platform 30 is formed in a box shape, and a space in which luggage is accommodated is formed inside. As shown in FIG. 2, a loading platform opening 34, which is a rectangular opening, is formed on the front surface 32 of the loading platform 30 (the facing surface facing the rear surface 22 of the cab 20). The loading platform opening 34 is formed at a position facing the cab opening 24. The size of the opening of the cargo bed opening 34 is substantially the same as the size of the opening of the cab opening 24.

  As shown in FIG. 2, the connecting portion 40 connects the cab 20 and the loading platform 30. A passage R through which a passenger or the like can walk through between the cab 20 and the loading platform 30 is formed in the connecting portion 40. The passage R is a passage between the cab opening 24 and the cargo bed opening 34.

  The hood member 50 is provided in the connecting portion 40 and covers the passage R. Further, the hood member 50 connects the cab 20 and the loading platform 30. Specifically, one end of the hood member 50 is connected to the periphery of the cab opening 24, and the other end of the hood member 50 is connected to the periphery of the cargo bed opening 34. The hood member 50 has flexibility and can be deformed. Thereby, even if the relative displacement of the cab 20 and the loading platform 30 mounted separately on the vehicle frame 10 occurs, the relative displacement can be absorbed by the hood member 50 being deformed.

  The surrounding member 60 is attached between the cab 20 and the loading platform 30, as shown in FIG. The surrounding member 60 is provided around the hood member 50 and surrounds the hood member 50. In other words, the surrounding member 60 surrounds the passage R between the cab 20 and the loading platform 30.

By the way, the surrounding member 60 is connected to the cab 20 while not being connected to the loading platform 30 so as not to prevent the cab 20 and the loading platform 30 from moving separately. For this reason, there exists a possibility that water may pass through the clearance gap between the surrounding member 60 and the loading platform 30 above the connection part 40, and may approach into the channel | path R (top member 50). For example, when it is raining, water may enter through the gap, or water that has accumulated on the loading platform 30 may move into the gap and enter when the vehicle 1 stops. .
On the other hand, in this embodiment, although details will be described later, a bracket is provided below a gap between the surrounding member 60 and the loading platform 30, and the bracket supplies water to the vehicle width direction end side of the vehicle 1. Has the function of draining water. Thereby, the water which passed the clearance gap can be discharged | emitted appropriately.

<Detailed configuration of the upper portion of the connecting portion 40>
Here, the configuration of the hood member 50, the surrounding member 60, and the peripheral portion in the upper part of the connecting portion 40 will be described with reference to FIG.

  FIG. 3 is a schematic diagram showing the internal configuration of part A of FIG. As shown in FIG. 3, the hood member 50 includes one end portion 52 on one end side in the width direction, the other end portion 53 on the other end side in the width direction, and a connection portion 54 connecting the one end portion 52 and the other end portion 53. Have

  One end 52 of the hood member 50 is fixed to a panel around the cab opening 24 of the cab 20. Specifically, the one end 52 is fixed by a fastening member 28a such as a screw while being sandwiched between brackets 26 and 27 on the indoor side of the cab 20.

The other end portion 53 of the hood member 50 is fixed to a panel around the loading platform opening 34 of the loading platform 30. Specifically, the other end portion 53 is fixed by a fastening member 38 a in a state sandwiched between the panel and the loading platform side bracket 36.
The connecting portion 54 of the hood member 50 is bent (curved) as shown in FIG. The connecting portion 54 functions as a covering portion that covers the passage R.

  In the upper part of the connection part 40, the surrounding member 60 is located above the hood member 50, as shown in FIG. One end 62 of the surrounding member 60 is connected to the cab 20 (the panel of the roof 21 in FIG. 3). On the other hand, the other end 63 of the surrounding member 60 is not connected to the loading platform 30 and is separated from the loading platform 30. For this reason, as shown in FIG. 3, a gap G exists between the other end 63 and the front surface 32 of the loading platform 30.

  Under the gap G (in other words, the other end 63 of the surrounding member 60), the above-described load carrier side bracket 36 is located. The loading platform side bracket 36 is a bracket provided around the loading platform opening 34.

  FIG. 4 is a schematic diagram for explaining the configuration of the loading platform side bracket 36. As shown in FIG. 4, the loading platform side bracket 36 includes an upper bracket 36 a positioned above the loading platform opening 34, and a left bracket 36 b and a right bracket 36 c positioned on both sides of the loading platform opening 34.

  As shown in FIG. 4, the upper bracket 36 a is provided along the vehicle width direction of the vehicle 1 (Y direction in FIG. 4). For example, the upper bracket 36a is disposed horizontally in the vehicle width direction. However, the present invention is not limited to this, and the upper bracket 36a may be disposed so as to be inclined (for example, the center side in the vehicle width direction is high and becomes low toward both ends). Further, the upper bracket 36a is disposed directly below the gap G. The upper bracket 36a arranged in this manner has a function of a drainage member that drains water toward the end in the vehicle width direction.

  FIG. 5 is a schematic diagram for explaining water passing through the gap G. FIG. In FIG. 5, the manner in which water falls is indicated by broken lines. The water falling through the gap G is received by the upper bracket 36a located directly below the gap G. And the water which fell to the upper bracket 36a is drained to the both ends side of a vehicle width direction along the upper bracket 36a. Thereby, the water which passes the clearance gap G can be discharged | emitted appropriately. The water that has flowed to both ends in the vehicle width direction may flow downward of the vehicle 1 along, for example, the left bracket 36b and the right bracket 36c.

  The upper bracket 36a is formed in an L shape as shown in FIG. 3, and includes a fixing portion 37a and a rail portion 37b. The fixing portion 37a is fixed to the front surface 32 of the loading platform 30 via a fastening member 38a. The rail part 37b protrudes toward the back surface 22 of the cab 20, and has a function of receiving and draining water as shown in FIG.

  The rail portion 37b of the upper bracket 36a is located above the connection portion 54 that is a cover portion that covers the passage R of the hood member 50. Thereby, it can suppress that the water which passed the clearance gap G falls to the connection part 54 of the hood member 50. FIG. For example, when water that has accumulated on the loading platform 30 passes through the gap G and falls to the connecting portion 54 at a time when the vehicle 1 is stopped, an excessive tension acts on the connecting portion 54, and the connecting portion 54 is Risk of damage. On the other hand, since the rail part 37b of the upper bracket 36a is located above the connection part 54, it can suppress that water falls to the connection part 54, Therefore It can prevent that the connection part 54 is damaged. In addition, the rail part 37b may protrude to the back surface 22 vicinity of the cab 20, and can suppress more effectively that water falls to the connection part 54 in this case.

  In addition to the drainage function, the upper bracket 36a also has a function of fixing the other end 53 of the hood member 50. That is, the upper bracket 36 a fixes the other end portion 53 of the hood member 50 around the cargo bed opening 34. Thus, the number of parts can be reduced because the upper bracket 36a also has a plurality of functions.

<Effect in this embodiment>
