Preferred embodiments of the present disclosure will be described in detail below with reference to the accompanying drawings. In the present specification and the drawings, components having substantially the same function are designated by the same reference numerals, so that duplicate description will be omitted.

(Overall configuration of relay box mounting structure)
Hereinafter, an example of the configuration of the relay box mounting structure according to the embodiment will be described. In this embodiment, an example in which the relay box is mounted on the cab-over type vehicle is described.

Each figure shows a common Cartesian coordinate system (X, Y, Z) in order to clarify the positional relationship of each configuration. In the following, the positive direction of the X-axis represents the front of the vehicle (hereinafter, abbreviated as "forward"), the positive direction of the Y-axis represents the width direction of the left side of the vehicle, and the positive direction of the Z-axis represents the top of the vehicle. It will be described as representing a direction (hereinafter, abbreviated as "upward direction"). However, these directions do not limit the posture when the relay box of the present invention is used.

FIG. 1 is a diagram showing an example of a mounting state of the relay box 1 in the vehicle C. FIG. 2 is a diagram showing a state in which the relay box 1 is removed in FIG. It should be noted that FIGS. 1 and 2 show a storage space formed between the front panel CF and the instrument panel (not shown) in the cab of the vehicle C.

A relay box 1 and an HVAC (Heating, Ventilating and Air-Conditioning) unit C1 (air conditioner) are housed in a storage space between the front panel CF and the instrument panel in the cab of the vehicle C. The HVAC unit C1 is composed of, for example, a heat exchanger unit C1a and a blower unit C1b, and the heat exchanger unit C1a and the blower unit C1b are arranged side by side in the vehicle width direction. The relay box 1 is arranged so as to cover the HVAC unit C1.

The relay box 1 is attached to a reinforcement C2 (corresponding to the "support member" of the present invention) extending along the vehicle width direction in the vehicle C. The reinforcement C2 is a rod-shaped reinforcing material whose one end and the other end are fixed to the side panels on both sides of the vehicle C. The reinforcement C2 has a claw portion C2a (two claw portions C2a in the present embodiment) between one end and the other end of the reinforcement C2, and the relay box 1 is fixed by the claw portion C2a. ing.

The claw portion C2a is formed so as to protrude rearward (minus X direction) from the reinforcement C2, for example. The claw portion C2a has, for example, a flat plate shape in which the plate surface faces in the vertical direction, and is formed to penetrate from the upper surface side to the lower surface side of the plate surface in a substantially central region of the plate surface (the present invention). (Equivalent to the "fitting receiving structure").

FIG. 3 is a diagram showing an example of the configuration of the relay box 1.

The relay box 1 is equipped with electrical components such as relays and fuses. Wiring (not shown) extending from various devices mounted on the vehicle C is connected to the relay box 1, and the electric components mounted on the relay box 1 are electrically connected to the various devices via the wiring. It is connected.

The relay box 1 has a main body 10 on which electrical components are mounted, and a block member 20 attached to the main body 10. The main body 10 of the relay box 1 according to the present embodiment has a rectangular parallelepiped shape in which the main surface on which the electric components are mounted is substantially rectangular. The block member 20 is attached to the outer side surface of the main body 10 (meaning a surface on the lateral side with respect to the main surface on which the electric component is mounted. The same applies hereinafter).

A plurality of slide guide grooves 11 are formed on the outer side surface of the main body 10, and when the block member 20 is attached to the main body 10, the attachment location to the main body 10 is set among the plurality of slide guide grooves 11. You can choose from any of them. More specifically, in the present embodiment, the slide guide grooves 11 are formed at two locations on the upper side surface of the main body 10, two locations on the left side surface of the main body 10, and two locations on the right side surface of the main body 10.

FIG. 4 is a diagram showing an example of the work of attaching the block member 20 to the main body 10 of the relay box 1.

For example, the block member 20 has a slide fitting groove 23 formed on one side surface (lower side surface in the present embodiment) of the block member 20 formed on the outer side surface (upper side surface in the present embodiment) of the main body 10. It is fixed to the main body 10 by fitting into the slide guide groove 11. In the slide fitting groove 23, a convex portion 23a that is hooked on the locking projection 11a formed in the slide guide groove 11 of the main body 10 is formed, and the locking projection 11a and the convex portion 23a are locked. Therefore, the fixed state of the main body 10 and the block member 20 is maintained.

When attaching the block member 20 to the main body 10, the operator fits the slide fitting groove 23 of the block member 20 into the slide guide groove 11 formed in the main body 10, and in this state, the block member 20 The slide fitting groove 23 of the above is slid and moved along the slide guide groove 11. Then, the operator slides the slide fitting groove 23 of the block member 20 so as to push it along the slide guide groove 11, so that the convex portion 23a formed in the slide fitting groove 23 of the block member 20 is formed. Overcomes the locking projection 11a formed in the slide guide groove 11. As a result, the convex portion 23a is caught and engaged with the locking projection 11a, and the block member 20 is fixed to the main body 10.

The block member 20 may be detachable from the main body 10. In that case, for example, the convex portion 23a provided in the slide fitting groove 23 may be elastically deformable.

(Detailed configuration of relay box mounting structure)
FIG. 5 is a diagram showing an example of the configuration of the block member 20 of the relay box 1. FIG. 6 is a diagram showing a state in which the claw portion C2a disposed on the reinforcement C2 is inserted into the block member 20 and the block member 20 and the reinforcement C2 are fixed.

7A and 7B are views showing the work when the relay box 1 is attached to the reinforcement C2. FIG. 8 is a diagram showing an operation when the relay box 1 is removed from the reinforcement C2. 7A, 7B, and 8 are side sectional views of the relay box 1.

The block member 20 has an insertion hole 21, a lever portion 22, and a slide fitting groove 23. The block member 20 has, for example, a substantially rectangular parallelepiped shape.

The insertion hole 21 is, for example, a through hole formed in the block member 20 along the ± X direction, and has a shape into which the claw portion C2a can be inserted. More specifically, the insertion hole 21 has a shape that fits with the claw portion C2a so that the claw portion C2a does not rattle when the claw portion C2a is inserted.

The lever portion 22 is provided at a position in the block member 20 where the claw portion C2a comes into contact with the tip of the claw portion C2a when the claw portion C2a is inserted into the insertion hole 21. Here, the lever portion 22 represents the exit of the insertion hole 21 (out of one end and the other end of the insertion hole 21, the side where the tip of the claw portion C2a is exposed when the claw portion C2a is inserted into the insertion hole 21. . The same applies below). The lever portion 22 is formed so that the extending direction from its base end position to the tip end is along the insertion direction (plus X direction) of the claw portion C2a.

Here, the lever portion 22 is configured to be elastically deformable, and when the claw portion C2a is inserted into the insertion hole 21, the upper surface (the surface on the plus Z direction side) is pressed against the claw portion C2a, and the lever is concerned. The tip of the portion 22 is configured to be pushed down toward the lower side (minus Z direction side) with respect to the position of the base end of the lever portion 22. Specifically, the lever portion 22 has a protrusion 22a (corresponding to the “fitting structure” of the present invention) on the upper surface thereof. Then, when the claw portion C2a is inserted into the insertion hole 21, the tip of the claw portion C2a presses the protrusion 22a diagonally downward, so that the tip of the lever portion 22 moves with respect to the base end position of the lever portion 22. And is pushed down. The protrusion 22a has, for example, an inclined shape that is inclined upward from the base end position of the lever portion 22 toward the tip of the lever portion 22.

Further, the protrusion 22a has a shape that fits with the opening C2aa formed in the claw portion C2a. As a result, when the claw portion C2a is inserted into the insertion hole 21 until the tip of the claw portion C2a reaches the vicinity of the tip of the lever portion 22, the tip of the lever portion 22 is on the lower side with respect to the base end position of the lever portion 22. In the state of being elastically deformed, the protrusion 22a is in a state of fitting with the opening C2aa formed in the claw portion C2a (see FIG. 7B). As a result, the relay box 1 is fixed to the reinforcement C2.

The block member 20 is formed with a space 22R below the lever portion 22 (in the minus Z direction) so that the lever portion 22 can be pushed down. Then, the lever portion 22 is pressed in the direction in which the protrusion 22a (lever portion 22) and the opening C2aa (claw portion C2a) are separated from each other, so that the fitting state between the protrusion 22a and the opening C2aa is released. It is possible (see FIG. 8). As a result, the fixed state of the relay box 1 and the reinforcement C2 is released.

The configuration of the slide fitting groove 23 is as described above with reference to FIG. The slide fitting groove 23 is a slide groove that fits into the slide guide groove 11 formed on the outer side surface of the main body 10. In the slide fitting groove 23, a convex portion 23a that is hooked on the locking projection 11a formed in the slide guide groove 11 of the main body 10 is formed.

The work of attaching / detaching the relay box 1 is as follows.

When attaching the relay box 1 to the reinforcement C2, the operator inserts the claw portion C2a formed in the reinforcement C2 into the insertion hole 21 formed in the block member 20 of the relay box 1. As such, the relay box 1 is brought closer to the reinforcement C2 (see FIG. 7A). Then, after the claw portion C2a formed in the reinforcement C2 is inserted into the insertion hole 21 formed in the block member 20, the operator can see that the tip of the claw portion C2a is near the tip of the lever portion 22. Until then, the relay box 1 is further brought closer to the reinforcement C2. As a result, the tip of the lever portion 22 is pushed down by the claw portion C2a, and the protrusion 22a of the lever portion 22 fits into the opening C2aa of the claw portion C2a (see FIG. 7B). As a result, the relay box 1 and the reinforcement C2 are in a fixed state.

When removing the relay box 1 from the reinforcement C2, the operator pushes down the lever portion 22 to separate the protrusion 22a formed on the lever portion 22 from the opening C2aa formed on the claw portion C2a ( See FIG. 8). As a result, the fitted state of the protrusion 22a and the opening C2aa is released, and the fixed state of the relay box 1 and the reinforcement C2 is released. Then, in this state, the relay box 1 is removed from the reinforcement C2 by pulling out the claw portion C2a from the insertion hole 21 formed in the block member 20.

[effect]
As described above, according to the mounting structure of the relay box 1 according to the present embodiment, the relay box 1 is attached to the support member of the vehicle C (for example, the reinforcement provided on the front panel CF side) so that the relay box 1 can be easily attached and detached. It can be fixed to the ment C2). In particular, according to the mounting structure of the relay box 1 according to the present embodiment, the relay box 1 can be fixed to the support member of the vehicle C without using a tool, so that the attachment / detachment work is easy. In addition to the improvement, the work time of the attachment / detachment work can be shortened.

Further, in the mounting structure of the relay box 1 according to the present embodiment, a block member 20 separate from the main body 10 of the relay box 1 is prepared, and the relay box 1 is connected via the block member 20 attached to the main body 10. The structure is fixed to the support member of the vehicle C. As a result, the relay box 1 can be attached to the support member without depending on the arrangement position of the claw portion C2a provided on the support member of the vehicle C. In other words, this makes it possible to apply the mounting structure according to the present embodiment to various vehicles having different arrangement positions of the in-vehicle devices.

(Other embodiments)
The present invention is not limited to the above embodiment, and various modifications can be considered.

For example, in the above embodiment, as a configuration for fixing the relay box 1 and the reinforcement C2, the protrusion 22a formed on the lever portion 22 and the opening C2aa formed on the claw portion C2a are fitted. The structure is shown. However, in the mounting structure of the relay box 1 of the present invention, other configurations may be used as long as the fitting structure is formed in the lever portion 22 and the fitting receiving structure is formed in the claw portion C2a. For example, an opening may be formed in the lever portion 22 and a protrusion may be formed in the claw portion C2a.

Further, in the above embodiment, as an example of the relay box 1, a configuration in which the block member 20 is attached to the main body 10 is shown. However, the block member 20 and the main body 10 do not necessarily have to be separate bodies, and the structure of the block member 20 may be formed on the main body 10.

Further, in the above embodiment, a storage space between the front panel of the cab and the instrument panel is shown as an example of the arrangement position of the relay box 1. However, the arrangement position of the relay box 1 is arbitrary. For example, in the case of a passenger car, the relay box 1 may be arranged in the engine room. Similarly, the support member to which the relay box 1 is attached may be a member other than the infoment C2.

Although specific examples of the present invention have been described in detail above, these are merely examples and do not limit the scope of claims. The techniques described in the claims include various modifications and modifications of the specific examples illustrated above.

According to the relay box mounting structure according to the present disclosure, the relay box can be easily mounted and removed.
