(Overall configuration of mobile unit)
The moving body 1 is a vehicle having three wheels or four or more wheels (four wheels in this example) that moves along a predetermined route set in advance.

The movable body 1 includes a drive source (not shown) such as an electric motor, an energy supply source (not shown) such as a power source, and electric parts 5 such as a control device 5a (specifically, a control board). The mobile body 1 is driven by a drive source when energy is supplied from the energy supply source. In this example, the power source is a rechargeable battery, and mainly supplies power for performing a travel function, a distance detection function, and a communication function.

The moving body 1 can change the traveling speed and / or the traveling direction D by controlling the driving of the wheels 6 to 6 with an instruction signal from the control device 5a. In this example, the mobile body 1 independently drives and controls the two left wheels 6 (6a) and 6 (6b) and the two right wheels 6 (6a) and 6 (6b). The traveling direction D can be changed by providing a difference in speed. The moving body 1 can turn (fixed turning) without changing the position by setting the rotation directions to opposite directions. The moving body 1 mainly moves straight forward (advancing direction D of an arrow in FIGS. 1 to 3). The moving body 1 may use, for example, an endless track including an endless belt installed on wheels [6 (6a), 6 (6b)], [6 (6a), 6 (6b)].

Such a moving body 1 can be used as a monitoring robot that monitors a monitoring target (detected object) such as a suspicious person or a suspicious object while communicating with a monitoring center, for example.

In this example, the moving body 1 includes a monitoring device 7 (specifically, an image capturing unit) and an arm unit 8 and is an autonomous traveling type monitoring vehicle.

The moving body 1 includes a lower unit 2 and an upper unit 3, and the upper unit 3 can be opened and closed with respect to the lower unit 2 via a hinge portion 4. That is, the moving body 1 has a so-called clamshell mechanism. The moving body 1 also includes an exterior part 200 (specifically, exterior covers) that covers the lower unit 2 and the upper unit 3.

The lower unit 2 is provided with electrical components 5 such as a drive source, a power source, and a control device 5a. Specifically, electrical components 5 such as a drive source, a power source, and a control device 5 a are provided in the lower unit 2. The electrical components 5 protrude slightly upward from the upper opening of the lower unit 2.

The upper unit 3 is provided with a monitoring device 7 and an arm unit 8. Specifically, the arm portion 8 is a long member having one end provided on the upper surface of the upper unit 3 and the other end provided with the monitoring device 7. The arm portion 8 is configured to rotate from the place where it is disposed on the upper unit 3, and the monitoring device 7 provided at the other end can be moved in the vertical direction V by rotating. In this example, the image capturing unit that functions as the monitoring device 7 is a PTZ (pan / tilt / zoom) camera, and is controlled by the control device 5a to capture an image and video around the moving body 1. Note that the moving body 1 may be provided with not only an image capturing unit but also a detection unit such as a sensor that detects an object as the monitoring device 7.

The lower unit 2 and the upper unit 3 have the same or substantially the same shape when viewed from above. The lower unit 2 and the upper unit 3 may have any shape such as a polygonal shape, a circular shape, and an elliptical shape when viewed from above. Moreover, the outer wall surface 2a of the lower unit 2 and the outer wall surface 3a of the upper unit 3 may be formed linearly or may be formed curvedly.

In this example, the lower unit 2 and the upper unit 3 are quadrangular (specifically, a long rectangular shape in the traveling direction) when viewed from above. The outer wall surface 2 a of the lower unit 2 is linearly formed along the vertical direction V or the substantially vertical direction V. The outer wall surface 3a of the upper unit 3 is linearly formed along the vertical direction V or the substantially vertical direction V when the upper unit 3 is closed.

The lower unit 2 and the upper unit 3 have the outer wall surfaces 2a, 3a on the outer periphery aligned or substantially aligned when the upper unit 3 is closed (fully closed). The lower unit 2 and the upper unit 3 are box-type units opened on opposite sides.

The movable body 1 has a predetermined opening smaller than 90 degrees with respect to the lower unit 2 around the rotation shaft 4a (rotation axis) of the hinge portion 4 provided in the lower unit 2 and the upper unit 3. It is possible to open (open) up to an angle θa (see FIG. 2).

Here, the opening angle θa is an angle when the upper unit 3 is fully opened with respect to the lower unit 2 (when fully opened), and is, for example, any angle between 40 degrees and 45 degrees. Can do.

In this example, the opening angle θa is approximately 40 degrees (40 degrees or approximately 40 degrees). The hinge portion 4 is provided on the rear side (specifically, the rear end portion) of the lower unit 2 and the upper unit 3, and is configured such that the rotation shaft 4a of the hinge portion 4 is along the left-right direction H1. . In addition, the hinge part 4 is provided in the front side (specifically front end part) of the lower unit 2 and the upper unit 3, and it is comprised so that the rotating shaft 4a of the hinge part 4 may follow the left-right direction H1. May be. The hinge portion 4 is provided on the left side (specifically, the left end portion) or the right side (specifically, the right end portion) of the lower unit 2 and the upper unit 3, and the pivot shaft 4 a of the hinge portion 4. May be configured along the front-rear direction H2.

The moving body 1 is provided with a support member 9 for supporting the upper unit 3 with respect to the lower unit 2 when the upper unit 3 is open. Thereby, the moving body 1 can prevent the upper unit 3 from descending in the open state. Examples of the supporting member 9 include a damper such as a gas damper and a biasing member such as a spring. In this example, the support member 9 is a gas damper. The support member 9 is biased in the closing direction up to a predetermined angle (for example, about 15 degrees) in the angle range larger than 0 degree and smaller than the opening angle θa, and is pushed in the opening direction when the predetermined angle is exceeded. It is supposed to be a structure that is The movable body 1 is configured to be restricted from rotating in the opening direction of the upper unit 3 so that the upper unit 3 does not open any more when the upper unit 3 opens to a predetermined opening angle θa.

The moving body 1 is provided with a lock member 10 for locking the upper unit 3 with respect to the lower unit 2 when the upper unit 3 is closed. As the lock member 10, a conventionally known member can be used, and detailed description thereof is omitted here.

Further, a central component 14 including the components of the movable body 1 is provided on the front side (specifically, the front end portion) of the upper unit 3 of the movable body 1 and in the central portion in the left-right direction H1. .

In this example, the central configuration unit 14 is provided with an optical detection unit 14a that optically detects an object to be detected.

Here, as the optical detection unit 14a, any device can be used as long as it detects light to be detected using light. As the optical detection unit 14a, for example, a lidar (Lighter: Light Detection and Ranging or Laser) that identifies the position, distance, and shape of the detected object by irradiating the detected object with a light beam (specifically, laser light). Imaging Detection and Ranging), imaging camera (imaging camera), and the like.

As the Lidar, typically, a detected object is detected in a detection range in both the horizontal direction H and the vertical direction V, or a two-dimensional Lidar (so-called 2DLidar) that detects a detected object in the detection range in the horizontal direction H. A three-dimensional Lidar (so-called 3DLida) can be exemplified. For example, the two-dimensional Lidar and the three-dimensional Lidar can detect an object to be detected in real time with a moving image and / or a still image.

Further, as an imaging camera, typically, a camera provided with an imaging element such as a CCD (Charge Coupled Device) image sensor having sensitivity to visible light or a CMOS (Complementary Metal Oxide Semiconductor) image sensor can be exemplified. The imaging camera can, for example, capture the object to be detected in real time with a moving image and / or a still image. Note that the imaging camera may be one that captures images using infrared light and / or ultraviolet light instead of / in addition to visible light.

In addition, other components of the moving body 1 are provided on the front side (specifically, the front end portion) of the upper unit 3 of the moving body 1 and on both sides (specifically, both end portions) in the left-right direction H1. Both end constituent parts 15 are provided.

In this example, the both-end component 15 is provided with a headlight 15a and an ultrasonic detector 15b.

When the mobile body 1 is splashed with water (for example, the exterior portion 200 of the lower unit 2 due to the water falling from the exterior portion 200 of the central component 14 in the upper unit 3 when the upper unit 3 is opened). Drainage structure for draining to the outside, in order to effectively prevent intrusion of water into the interior and water permeation from the exterior part 200 of the both-end component 15 in the upper unit 3 into the exterior part 200 of the lower unit 2) 100 is provided. Next, the drainage structure 100 will be described in detail.

<Drainage structure>
[Drainage member]
FIG. 4 is a schematic cross-sectional view showing the drainage member 110 in a state where the exterior part 200 and the like are removed from the moving body 1 shown in FIG. FIG. 5 is a schematic cross-sectional view showing an enlarged drainage member 110 portion in the moving body 1 shown in FIG.

6 is a schematic configuration diagram showing a state in which the lower unit 2 and the upper unit 3 are extracted from the moving body 1 shown in FIG. FIG. 7 is a schematic configuration diagram showing a drainage member 110 portion R1 in the upper unit 3 shown in FIG.

8 shows the positional relationship between the flange 111 and the lower unit 2 in the drainage member 110 provided on the outer wall surface 3a of the upper unit 3 in the lower unit 2 and the upper unit 3 shown in FIG. It is the schematic perspective view seen.

By the way, in the mobile body 1, when using in the place where water W (refer FIG.4, FIG.5, FIG.7) (specifically rain) is applied (for example, when using outdoors), water is contained in the mobile body 1. W may enter, and inconvenience due to the entry of water W (for example, failure of the electrical components 5 (see FIGS. 4 and 6) such as the control device 5a (see FIGS. 4 and 6)) may occur. There is.

In this respect, in this embodiment, the drainage structure 100 (see FIG. 4) includes a drainage member 110 (see FIGS. 3 and 4 to 8) provided on the outer wall surface 3a of the upper unit 3. The drainage member 110 has a flange 111 (see FIGS. 4 to 8) that protrudes from the outer wall surface 3 a of the upper unit 3. In the state where the upper unit 3 is closed, the drainage member 110 is configured such that the tip 111a (see FIGS. 4 and 5) side of the flange 111 faces downward (see FIGS. 4 and 5). Here, the state in which the upper unit 3 is closed means that the upper unit 3 is in a fully closed state with respect to the lower unit 2.

According to the present embodiment, since the drainage member 110 is provided on the outer wall surface 3a of the upper unit 3, the entire moving body 1 does not have to be completely waterproof, and the cost can be reduced accordingly. Further, since the drainage member 110 is provided on the outer wall surface 3a of the upper unit 3, it is possible to make it difficult to be restricted in design. And the drainage member 110 has the collar part 111 which protrudes in the outer wall surface 3a of the upper unit 3, and when the upper unit 3 is closed, it is comprised so that the front-end | tip 111a side of the collar part 111 may face downward. . Therefore, in a state where the upper unit 3 is closed, after the water W falling from above or the water W falling from above the flange 111 of the outer wall surface 3a of the upper unit 3 is received by the flange 111, It can be made to flow downward along the flange 111, and further, can be dropped outside the lower unit 2 to be drained. Thereby, the water W can be made difficult to enter the lower unit 2. Therefore, prior to opening the upper unit 3, the operator does not have to wipe off the water W accumulated in the upper unit 3, and therefore, deterioration of workability by the operator when opening the upper unit 3 is avoided. be able to.

In this example, a collar 111 is provided below the central component 14. In this way, when the upper unit 3 is opened, the water W effectively enters the exterior unit 200 of the lower unit 2 due to the water W falling from the exterior unit 200 of the central component 14 in the upper unit 3. Can be prevented.

Here, the above-described configuration and operation are based on the fact that the moving body 1 is installed on the horizontal installation surface S (see FIG. 4), and of course vary depending on the state of the installation surface S of the moving body 1. In addition, in this example, although the above-mentioned structure and operation | movement changed with the state of the installation surface S of the moving body 1, it changed above the inclination of the drainage structure 100 according to the state of the installation surface S of the moving body 1. You may comprise so that a structure and an effect | action may be maintained constant or substantially constant. The same applies to the drainage structures 100 in the first embodiment and later described later.

As shown in FIGS. 4 to 7, the flange 111 may be formed in a flat plate shape, or is not illustrated, but is formed in a curved shape that gradually curves downward toward the tip 111 a side. Also good.

By the way, in the state where the moving body 1 is installed on the horizontal installation surface S, the downward inclination angle θb1 (see FIG. 5) of the flange 111 with respect to the horizontal direction H when the upper unit 3 is closed (see FIG. 5). Is formed in a curved shape, if the angle with respect to the horizontal direction H of the imaginary tangent passing through the base end 111b (see FIGS. 5 and 7) of the flange 111 is too small, the water W will flow into the flange 111. Easy to accumulate. On the other hand, if the downward inclination angle θb1 is too large, the workability of attaching the drainage member 110 to the outer wall surface 3a of the upper unit 3 tends to deteriorate.

In this regard, in this embodiment, the downward inclination angle θb1 can be about 5 degrees to 15 degrees, for example. In this example, the downward inclination angle θb1 is approximately 10 degrees (10 degrees or approximately 10 degrees).

By doing so, it is possible to realize both the improvement of the flowability of the water W at the flange 111 and the improvement of the workability of attaching the drainage member 110 to the outer wall surface 3a of the upper unit 3.

Further, the protruding length L (length in the horizontal direction H) of the flange 111 (see FIG. 5) is set to a length that prevents the water W from entering the lower unit 2 when the upper unit 3 is closed. it can. Specifically, the protruding length L of the flange 111 is a length such that the tip 111a of the flange 111 is located on the outer side (front side in this example) of the lower unit 2 when the upper unit 3 is closed. be able to.

(First embodiment)
The drainage member 110 includes an outer wall surface 3a (3a1) (see FIGS. 3 to 7) on the front side (front side) of the upper unit 3 and an outer wall surface 3a (3a2) on the back side (rear side) (FIGS. 3 and 4). 6 and 8), left side (left side) outer wall surface 3a (3a3) (see FIGS. 3, 4, and 6), right side (right side) outer wall surface 3a (3a4). ) (See FIG. 3 and FIG. 8).

However, when the upper unit 3 is opened with respect to the lower unit 2, the lower end of the outer wall surface 3a (3a1) on the side opposite to the hinge portion 4 (see FIGS. 4 and 6) of the upper unit 3 (front side in this example). 3b (see FIGS. 4 to 7) is located above the inner region α (see FIG. 6) of the lower unit 2. In this case, the water W falling along the outer wall surface 3a (3a1) on the opposite side of the hinge portion 4 of the upper unit 3 falls inside the lower unit 2 [specifically, the location where inconvenience occurs when the water W enters. (For example, the location where the electrical components 5 such as the control device 5a are provided)].

In this respect, in the present embodiment, the drainage member 110 is provided on the outer wall surface 3a (3a1) on the opposite side of the hinge unit 4 of the upper unit 3.

Thus, when the upper unit 3 is opened with respect to the lower unit 2, the lower end 3 b of the outer wall surface 3 a (3 a 1) opposite to the hinge portion 4 of the upper unit 3 is connected to the inner region α of the lower unit 2. Water W can be reliably drained on the outer wall surface 3a (3a1) of the upper unit 3 opposite to the hinge portion 4. As a result, the water W on the outer wall surface 3a (3a1) of the upper unit 3 on the side opposite to the hinge portion 4 is moved into the lower unit 2 [particularly where inconvenience occurs when the water W enters (for example, the electric power of the control device 5a etc. It is possible to make it difficult to enter the part where the parts 5 are provided.

(Second Embodiment)
By the way, when the drainage member 110 is provided on the outer wall surface 3a (3a1) opposite to the hinge portion 4 of the upper unit 3, when the upper unit 3 is open, the tip 111a side of the flange 111 is When configured to face downward, there are the following disadvantages. In other words, the water W falling from above the flange 111 of the outer wall surface 3a (3a1) opposite to the hinge 4 of the upper unit 3 and the water W accumulated in the flange 111 are It flows toward the tip 111a and falls from the tip 111a. If it does so, the water W which falls from the front-end | tip 111a of the collar part 111 will enter the inside of the lower unit 2 easily. Here, the state where the upper unit 3 is open means that the upper unit 3 is fully open with respect to the lower unit 2.

Therefore, it is desirable that the water W falling from the flange 111 does not easily enter the lower unit 2.

In this regard, in the present embodiment, the drainage member 110 is configured such that the tip 111a side of the flange 111 faces upward when the upper unit 3 is open (see FIGS. 6 and 7).

By doing so, even when the upper unit 3 is opened relative to the lower unit 2 or / or in a further open state, the flange portion 111 of the outer wall surface 3a (3a1) opposite to the hinge portion 4 of the upper unit 3 is provided. The water W that has fallen down from above and the water W that has accumulated in the flange 111 are collected on the base end 111b (see FIGS. 6 and 7) of the flange 111, and the rotation shaft 4a ( It can be drained by dropping from both ends 111c, 111c (see FIG. 8) in the direction (see FIG. 4 and FIG. 6) (the horizontal direction H1 in this example). Thereby, the water W falling from the collar part 111 can be made difficult to enter the inside of the lower unit 2.

Here, when the movable body 1 is installed on the horizontal installation surface S, the upward inclination angle θb2 of the flange 111 with respect to the horizontal direction H in the state in which the upper unit 3 is open (see FIG. 7) (see FIG. 7) When 111 is formed in a curved shape, the angle of the imaginary tangent line passing through the base end 111b of the flange 111 with respect to the horizontal direction H) is determined by the opening angle θa and the downward inclination angle θb1. For example, when the opening angle θa is about 40 degrees and the downward inclination angle θb1 is about 5 degrees to 15 degrees, the upward inclination angle θb2 can be about 25 degrees to 35 degrees. In this example, the upward inclination angle θb2 is about 30 degrees.

Further, in the present embodiment, the drainage member 110 may be configured such that the tip 111a side of the flange 111 faces downward when the upper unit 3 is open. In this case, the protrusion length L (see FIG. 7) of the flange portion 111 is such that the tip 111a of the flange portion 111 is in the direction of the rotation axis 4a (rotation axis direction) of the hinge portion 4 when the upper unit 3 is open. It may be a length located on the outer side (the front side in this example) of the lower unit 2 in the orthogonal horizontal direction H (the front-rear direction H2 in this example).

By doing so, even when the upper unit 3 is opened relative to the lower unit 2 or / or in a further open state, the flange portion 111 of the outer wall surface 3a (3a1) opposite to the hinge portion 4 of the upper unit 3 is provided. In addition, the water W that has fallen from above and the water W that has accumulated in the flange 111 can be dropped from the tip 111a of the flange 111 to the outside of the lower unit 2 and drained. Thereby, the water W falling from the collar part 111 can be made difficult to enter the inside of the lower unit 2.

(Third embodiment)
By the way, when opening the upper unit 3 with respect to the lower unit 2, depending on the position where the hinge part 4 is provided and the shapes of the upper unit 3 and the lower unit 2, the hinge part 4 side of the upper unit 3 (rear side in this example) The lower end 3b (see FIG. 6) of the outer wall surface 3a (3a2) of the lower unit 2 may be located in or above the inner region α. In this case, the water W falling along the outer wall surface 3 a (3 a 2) on the hinge portion 4 side of the upper unit 3 easily enters the lower unit 2.

Therefore, in the present embodiment, the drainage member 110 can be illustrated as being provided on the outer wall surface 3a (3a2) of the upper unit 3 on the hinge portion 4 side.

Thus, when the upper unit 3 is opened with respect to the lower unit 2, even if the lower end 3b of the outer wall surface 3a (3a2) on the hinge part 4 side of the upper unit 3 is in the inner region α of the lower unit 2 or on the inner side Even if located above the region α, the water W can be reliably drained from the outer wall surface 3a (3a2) of the upper unit 3 on the hinge portion 4 side. Thereby, the water W on the outer wall surface 3 a (3 a 2) on the hinge portion 4 side of the upper unit 3 can be made difficult to enter the lower unit 2.

Here, the protrusion length L of the flange 111 is a horizontal direction H (in this example, the front-rear direction) in which the tip 111a of the flange 111 is orthogonal to the direction of the rotation axis 4a of the hinge 4 regardless of the open / closed state of the upper unit 3. In H2), the length is located outside the lower unit 2 (in this example, the rear side). Moreover, it is preferable that the collar 111 does not contact the lower unit 2 when the upper unit 3 is open.

(Fourth embodiment)
In the present embodiment, the flange 111 in the drainage member 110 has a flange size d1 (see FIG. 8) that is the same or substantially the same as the lower unit size d2 (see FIG. 8), or larger than the lower unit size d2. The mode made into the size can be illustrated. The collar size d1 is a horizontal direction H along the outer wall surface 3a of the upper unit 3 (in this example, the outer wall surface 3a (3a1) opposite to the hinge portion 4) (in this example, the pivot shaft 4a of the hinge portion 4). Direction) (longitudinal direction). The lower unit size d2 is the size of the lower unit 2 in the horizontal direction H (in this example, the direction of the rotating shaft 4a of the hinge portion 4) along the outer wall surface 2a (see FIGS. 4 to 6 and 8) of the lower unit 2. It is.

By doing so, the water W falling from above or the water W falling from above the flange 111 of the outer wall surface 3a of the upper unit 3 is moved along the horizontal direction H along the outer wall surface 2a of the lower unit 2 (this In the example, the hinge part 4 can escape to both outer sides in the rotation axis 4a direction (longitudinal direction). Thereby, the water W falling from the upper side and the water W falling from the upper side than the flange 111 of the outer wall surface 3 a of the upper unit 3 can be further prevented from entering the lower unit 2.

In this example, the collar part 111 has a collar part size d1 larger than the lower unit size d2. The flange 111 is a rectangular (specifically rectangular) flat plate member (specifically, a sheet-like member). In addition, you may chamfer the corner | angular part by the side of the front-end | tip 111a in the collar part 111 of a square-shaped flat plate member.

The collar 111 is a flat plate member in this example. However, the present invention is not limited to this, and the flange portion 111 has a plate-like portion that extends from the inside to the outside in the horizontal direction H along the outer wall surface 3a of the upper unit 3 (in this example, in the direction of the rotating shaft 4a of the hinge portion 4). It may be a plate-like member having a bent angle mountain shape (for example, a bent angle mountain shape bent at the central portion or substantially the central portion as an apex) that is bent so as to gradually become lower. Further, the flange portion 111 is configured such that the plate-like portion gradually becomes lower from the inside toward the outside in the horizontal direction H (in this example, the direction of the rotation axis 4a of the hinge portion 4) along the outer wall surface 3a of the upper unit 3. It may be a plate-like member having a curved arc shape that curves (for example, a curved arc shape that curves with the central portion or the substantially central portion as a vertex).

By doing so, it is possible to easily drop the water W from both ends 111c and 111c in the horizontal direction H along the outer wall surface 3a of the upper unit 3 of the collar unit 111.

(Fifth embodiment)
FIG. 9 is a schematic perspective view showing the drainage member 110 portion R2 in the upper unit 3 shown in FIG. In addition, since the drainage member 110 has substantially the same configuration on both sides in the horizontal direction H (left side and right side in this example), in FIG. 9, one side of the drainage member 110 (left side in this example) Only side).

By the way, the water W flowing through the drainage member 110 falls from a water drop fixed point P (see FIG. 9) that falls at a fixed position or a substantially fixed position in the drainage portion 110a (see FIGS. 8 and 9) in the drainage member 110. It is preferable. On the other hand, when the water W does not fall at a fixed position or a substantially fixed position in the drainage part 110a, that is, when the drainage part 110a is a horizontal plane or a plane close to the horizontal, the water W is a horizontal plane. Or, it cannot be specified from which position of the drainage part 110a which is a plane close to the horizontal.

Therefore, it is desired to drop the water W from the water drop fixed point P in the drainage part 110a of the drainage member 110 to specify the position where the water W falls.

In this respect, in the present embodiment, the drainage member 110 has a drainage portion 110a serving as a water drop fixed point P where the water W falls at a fixed position or a substantially fixed position regardless of the open / closed state of the upper unit 3.

In this way, the water W can be dropped at the water falling fixed point P in the drainage part 110a. Thereby, in the drainage part 110a in the drainage member 110, the water W can be dropped from the water fall fixed point P, and the fall position of the water W can be specified.

(Sixth embodiment)
In the present embodiment, the drainage portion 110a that becomes the water drop fixed point P is provided outside the lower unit 2 in the horizontal direction H (in this example, the horizontal direction H1). Specifically, the drainage part 110a is located on both outer sides of the lower unit 2 in the horizontal direction H (the horizontal direction H1 in this example) along the outer wall surface 3a of the upper unit 3 of the drainage member 110 regardless of the open / closed state of the upper unit 3. It is provided in the protruding part.

In this way, the water W can be reliably dropped outside the lower unit 2 in the horizontal direction H from the drainage part 110a. Thereby, the water W falling from the drainage part 110a can be further prevented from entering the lower unit 2.

(Seventh embodiment)
The drainage member 110 supports the flange 111 and is provided with a base 112 (FIG. 5) provided on the outer wall 3a of the upper unit 3 (in this example, the outer wall 3a (3a1) opposite to the hinge 4 of the upper unit 3). 7 to 9). The base 112 has a base size d3 (see FIG. 5) that is the size in the horizontal direction H (in this example, in the direction of the rotation axis 4a (rotation axis direction) and the horizontal direction H1 of the hinge 4) along the outer wall surface 3a of the upper unit 3. 8) is larger than the lower unit size d2. Further, the base 112 may have a base size d3 that is the same as or substantially the same as the collar size d1, but in this example, the base 112 is larger than the collar size d1.

And the drainage part 110a used as the water fall fixed point P is the both ends 112b and 112b in the horizontal direction H (this example left-right direction H1) along the outer wall surface 3a of the upper unit 3 of the base 112 (refer FIG. 8, FIG. 9). And the lower end 112c (see FIGS. 8 and 9) form a pair of corner portions 112d and 112d (see FIGS. 8 and 9) that form acute angles.

By doing so, the drainage portion 110a that becomes the water drop fixed point P can be easily formed with a simple configuration such as the base portion 112 that supports the flange portion 111 and is provided on the outer wall surface 3a of the upper unit 3. Can be realized.

In the present embodiment, the drainage portion 110a serving as the water drop fixed point P is configured to be the same or substantially the same regardless of the open / closed state of the upper unit 3. However, the present invention is not limited to this, and the drainage portion 110a serving as the water drop fixed point P may be configured to be different in a state where the upper unit 3 is open and in a closed state.

(Eighth embodiment)
The material that can be used for the flange 111 in the drainage member 110 may be a material having rigidity or a material having elasticity, as long as it functions as a rod. There may be. Examples of the material that can be used for the flange 111 include materials such as metal materials (specifically, sheet metal) and resin materials.

By the way, when work members 12 and 12 (see FIG. 8) [for example, detachable members (for example, connection connector CN) (see FIG. 8)] that require work by an operator are provided in the vicinity of the collar 111, the collar 111 This obstructs the workability of the work members 12 and 12 by the operator. In this regard, the drainage member 110 is detachably provided on the outer wall surface 3 a of the upper unit 3, and the drainage member 110 is detached from the upper unit 3 when an operator works on the work members 12 and 12. However, in this case, it takes time and effort to separate the drainage member 110 from the upper unit 3, and for example, it takes time to cope with an emergency.

Therefore, when an operator works on the work members 12 and 12, it is desired to reduce the effort and time for detaching the drainage member 110 from the upper unit 3, for example, to respond promptly in an emergency.

In this respect, in the present embodiment, the collar portion 111 is formed of a flexible material (a material that is elastically deformed).

In this way, when the worker works on the work members 12 and 12, the collar portion 111 can be bent elastically (recoverably) so that the worker can work easily. Work can be performed on the work members 12 and 12 in a state in which 111 is bent. Therefore, the operator can work on the work members 12 and 12 without detaching the drainage member 110 from the upper unit 3. Thereby, the effort and time which make the drainage member 110 detach | leave from the upper unit 3 can be reduced, for example, it can respond quickly in an emergency.

Here, as a material having flexibility, a resin material, typically, a PET (polyethylene terephthalate) resin can be used.

In this example, the collar 111 is made of PET resin and is transparent or light transmissive.

(Ninth embodiment)
FIG. 10 is a schematic configuration diagram illustrating an example of the drainage member 110 in the upper unit 3. FIG. 11 is a schematic configuration diagram illustrating another example of the drainage member 110 in the upper unit 3.

By the way, the drainage member 110 supports the flange portion 111 and includes a base 112 provided on the outer wall surface 3a of the upper unit 3 (in this example, the outer wall surface 3a (3a1) opposite to the hinge portion 4 of the upper unit 3). In the case where it has, the base 112 may have the lower end 112a positioned above the position of the upper end 2b of the lower unit 2 as shown in FIG. is there.

That is, the water W flowing along the base 112 not only falls from the lower end 112a of the base 112, but also easily enters the lower unit 2 side from the lower end 112a of the base 112 through the outer wall surface 3a of the upper unit 3.

Therefore, it is desirable to suppress the water W flowing along the base 112 from entering the lower unit 2 side.

In this regard, in the present embodiment, as shown in FIG. 11, the base 112 has a lower end 112a below the position of the upper end 2b of the lower unit 2 or the upper end 2b of the lower unit 2 when the upper unit 3 is closed. It is located at a position (lower than the upper end 2b of the lower unit 2 in this example).

By doing so, the water W flowing along the base 112 is easily flown into the position of the upper end 2b of the lower unit 2 of the base 112 or the lower end 112a located at a position lower than the upper end 2b of the lower unit 2. Can do. On the other hand, it is possible to make it difficult for the water W flowing along the base 112 to flow into the lower unit 2 side, and thus the amount of water W falling from the lower end 112a of the base 112 can be increased. Thereby, it can suppress that the water W which flows along the base 112 enters into the lower unit 2 side.

The flange 111 may be provided at any position in the vertical direction V of the outer wall surface 3a of the upper unit 3. However, in the case where the outer wall surface 3a of the upper unit 3 is provided with a protruding member 13 (see FIG. 8) protruding from the outer wall surface 3a (for example, the insertion member M for inserting the connection connector CN and the harness HN of the connection connector CN). In addition, it is preferable that the flange 111 is provided below the protruding member 13 (for example, the insertion member M through which the connection connector CN or the harness HN of the connection connector CN is inserted).

Note that the flange 111 is located near the lower unit 2 (specifically, the lower end of the upper unit 3 in the vertical direction V of the outer wall surface 3a of the upper unit 3 from the viewpoint of shortening the length of the base 112 in the vertical direction V. It is preferable to be provided at a position separated from 3b by a predetermined distance on the lower unit 2 side.

(10th Embodiment)
By the way, when the base 112 in the drainage member 110 extends linearly downward from the upper end 2b of the lower unit 2 as shown in FIG. 11, for example, due to some factor such as the condition of the hinge 4 or the like, If the outer wall surface 3a (3a1) opposite to the hinge portion 4 of the unit 3 is displaced inward with respect to the outer wall surface 2a opposite to the hinge portion 4 of the lower unit 2, the following inconvenience occurs. . That is, when the upper unit 3 is closed with respect to the lower unit 2, the base 112 may collide with the lower unit 2 and the upper unit 3 may not be closed. In some cases, the base 112 may be deformed or damaged.

FIG. 12 is still another example of the drainage member 110 in the upper unit 3 and is a schematic configuration diagram showing the drainage member 110 shown in FIGS. 4 to 9.

In this regard, in this embodiment, as shown in FIG. 12, the base 112 communicates with the base main body 1121 and the lower end 1121a of the base main body 1121 and gradually moves away from the lower unit 2 as it goes downward from the lower end 1121a. And a separation portion 1122.

By doing so, the outer wall surface 3a (3a1) on the opposite side to the hinge part 4 of the upper unit 3 is on the opposite side of the hinge part 4 of the lower unit 2 due to some factors such as the condition of the hinge part 4 etc. Even when the upper unit 3 is closed with respect to the lower unit 2, the separation portion 1122 in the base 112 can guide the upper unit 3 along the lower unit 2 even when the upper unit 3 is closed with respect to the outer wall surface 2 a. Thereby, the upper unit 3 can be closed reliably. Further, deformation or breakage of the base 112 can be avoided.

The separation portion 1122 is provided so as to be positioned in the vicinity of the lower unit 2 (a position where the upper unit 3 can be guided along the lower unit 2 when the upper unit 3 is closed) when the upper unit 3 is closed. Yes.

The separation portion 1122 in the base portion 112 may be formed in a flat plate shape as shown in FIG. 12, or although not shown, it is formed in a curved shape that gradually curves upward or downward as it goes to the distal end side. May be.

By the way, the separation angle θc of the separation portion 1122 with respect to the vertical direction V (specifically, the outer wall surface 2a of the lower unit 2) (see FIG. 12) [if the separation portion 1122 is formed in a curved shape, If the virtual tangent line passing through the upper end 1122b and the vertical direction V (specifically, the angle with respect to the outer wall surface 2a of the lower unit 2) is too small, when the upper unit 3 is closed with respect to the lower unit 2, the separation at the base 112 will occur. The part 1122 easily collides with the lower unit 2. On the other hand, if the separation angle θc is too large, the drainage portion 110a of the separation portion 1122 tends to be in a state where it does not fall at a fixed position or a substantially fixed position. That is, the drainage part 110a of the separation part 1122 tends to be a horizontal plane or a plane close to horizontal. If it does so, it cannot be specified from which position of the drainage part 110a of the separation | spacing part 1122 which is a horizontal plane or a plane near horizontal.

In this regard, in the present embodiment, the separation angle θc can be about 10 degrees to 30 degrees, for example. In this example, the separation angle θc is approximately 20 degrees (20 degrees or approximately 20 degrees).

By doing so, when the upper unit 3 is closed with respect to the lower unit 2, the collision of the separation part 1122 with the lower unit 2 in the base part 112 and the fixed position of the water W in the drainage part 110 a of the separation part 1122 or approximately It is possible to achieve compatibility with dropability at a fixed position.

(Eleventh embodiment)
By the way, when using the base part 112 which supports the collar part 111, when there is a clearance gap between the base part 112 and the collar part 111 and / or between the base part 112 and the outer wall surface 3a of the upper unit 3, as follows. There is an inconvenience. That is, the water W easily enters the lower unit 2 between the base 112 and the flange 111 and / or between the base 112 and the outer wall surface 3 a of the upper unit 3. This is particularly true when the base 112 and the collar 111 are partially fixed (in this example with partial fixing members SC to SC (see FIGS. 8 to 12) such as screws) and / or This becomes conspicuous when the base 112 and the outer wall surface 3a of the upper unit 3 are partially fixed (in this example, by partial fixing members SC to SC (see FIGS. 8 to 12) such as screws).

In this respect, in the present embodiment, the base 112 supports the flange 111 via the seal member 120 (121). Alternatively / further (further in this example), the base 112 is provided on the outer wall surface 3a of the upper unit 3 via the seal member 120 (122).

By doing so, the gap between the base 112 and the flange 111 and / or (and in this example), the base 112 and the outer wall surface 3a of the upper unit 3 can be eliminated or almost eliminated. This eliminates or almost eliminates the entry of water W between the base 112 and the flange 111 and / or (and in this example) between the base 112 and the outer wall surface 3a of the upper unit 3. As a result, the water W from the gap can be prevented from entering the lower unit 2. This is particularly true when the base portion 112 and the collar portion 111 are partially fixed (in this example, with partial fixing members SC to SC such as screws) and / or (as in the present embodiment) and / or ( In this example, this is effective when the base 112 and the outer wall surface 3a of the upper unit 3 are partially fixed (in this example, by partial fixing members SC to SC such as screws).

As a material that can be used for the seal member 120, any material can be used as long as it has a function such as weather resistance, waterproofness, and water-stopping property. For example, a soft member (specifically, A member made of a porous material), more specifically, urethane foam can be used. In this example, the seal member 120 is made of urethane foam (PORON (registered trademark) manufactured by Roger Sinoac Co., Ltd.) having a fine and substantially uniform high-density cell structure.

Specifically, the base main body 1121 (see FIGS. 10 to 12) is provided on the first main body 11211 (see FIGS. 10 to 12) that supports the flange 111 and the outer wall surface 3a of the upper unit 3. It has a second main body 11212 (see FIGS. 10 to 12). The first main body 11211 and the second main body 11212 are integrally formed. The first body portion 11211 and the second body portion 11212 have the same or substantially the same thickness. The first main body 11211 is bent at a predetermined angle (90 degrees-downward inclination angle θb1) with respect to the second main body 11212. The base main body 1121 (specifically, the second main body 11212) and the separation portion 1122 (see FIG. 12) are integrally formed. The base main body 1121 (specifically, the second main body 11212) and the separation portion 1122 have the same or substantially the same thickness. The separation portion 1122 is bent at a predetermined angle (180 degrees−separation angle θc) with respect to the base main body portion 1121 (specifically, the second main body portion 11212).

For example, the base 112 can be formed by pressing and bending a flat sheet metal.

The seal member 120 (121) is bonded to the inner (lower) surface of the first main body 11211 with an adhesive member N such as an adhesive or a double-sided pressure-sensitive adhesive sheet. Similarly, the seal member 120 (122) is bonded to the outer surface (the rear side in this example) of the second main body 11212 with an adhesive member N such as an adhesive or a double-sided pressure-sensitive adhesive sheet.

4 to 9 and 12, the seal member 120 (122) is gradually separated from the lower unit 2 as it goes downward, like the separation portion 1122. Specifically, the seal member 120 (122) is bonded to the outer surface (rear side in this example) of the separation portion 1122 by an adhesive member N (see FIG. 12) such as an adhesive or a double-sided pressure-sensitive adhesive sheet.

The sealing member 120 (122) can be provided such that the lower end is below the lower end of the base 112 (the separation portion 1122 in the base 112 in the configuration shown in FIGS. 4 to 9 and 12). In this case, the lower end portion of the seal member 120 (122) can also be the drainage portion 110a (see FIG. 12) that becomes the water drop fixed point P (the lowest point in this example).

Both ends 112b and 112b (see FIGS. 8 and 9) of the base portion 112 (the separation portion 1122 in the configuration shown in FIGS. 4 to 9 and 12) and the height of the lower end 112c (see FIGS. 8 and 9) respectively forming an acute angle. The position (height position from the installation surface S (see FIG. 4)) is from the inside to the outside in the horizontal direction H (in this example, the direction of the rotation axis 4a of the hinge portion 4) along the outer wall surface 3a of the upper unit 3. As it goes to (in this example, regardless of the open / closed state of the upper unit 3), it gradually becomes lower (see FIGS. 8 and 9). Specifically, the lower end 112c of the base 112 is inclined at predetermined corner angles θd and θd (see FIGS. 8 and 9) with respect to both ends 112b and 112b. If the corner angle θd is too large, the drainage portion 110a tends to be in a state where it does not fall at a fixed position or a substantially fixed position. On the other hand, if the corner angle θd is too small, the adhesion area between the base portion 112 (specifically, the separation portion 1122) and the seal member 120 (122), and hence the adhesion due to the adhesion member N, tends to decrease. Accordingly, the corner angle θd can be about 2 to 6 degrees, for example. In this example, the corner angle θd is about 4 degrees (4 degrees or substantially 4 degrees).

By doing so, it is possible to realize both the dropability of the water W at the fixed position or substantially fixed position in the drainage section 110a and the adhesion of the adhesive member N to the base 112 and the seal member 120 (122).

The flange 111 and the seal member 120 (121) have through holes t1 to t1 and t2 to t2 (see FIGS. 10 to 12) penetrating one or more (seven in this example) fixing members SC to SC. Is provided. The first main body portion 11211 is provided with fixing portions F1 to F1 (see FIGS. 10 to 12) for fixing the fixing members SC to SC (in this example, a female screw that is screwed with a male screw of the fixing member SC). It has been. The flange 111 and the seal member 120 (121) are detached from the fixing portions F1 to F1 in a state where the fixing members SC to SC are inserted into the through holes t1 to t1 and t2 to t2 from the inner side (lower side in this example). The first main body 11211 is detachably provided by being fixed (screwed in this example).

The second main body 11212 and the seal member 120 (122) include through holes t3 to t3 and t4 to t4 (see FIGS. 10 to 12) penetrating one or more (four in this example) fixing members SC to SC. ) Is provided. Fixing portions F2 to F2 (see FIGS. 10 to 12) for fixing the fixing members SC to SC on the outer wall surface 3a of the upper unit 3 (in this example, a female screw that is screwed with a male screw of the fixing member SC) Is provided. The second main body 11212 and the seal member 120 (122) have the fixing members F2 to F2 in a state where the fixing members SC to SC are inserted into the through holes t3 to t3 and t4 to t4 from the inside (in this example, the front side). Is detachably fixed (screwed in this example) to the outer wall surface 3a of the upper unit 3 so as to be detachable.

The exterior part 200 that covers the upper unit 3 is provided with a drainage structure 100 for discharging the water accumulated inside to the outside. Specifically, the exterior part 200 that covers the upper unit 3 is provided with a bent part 201 having a portion inclined in the height direction (vertical direction V) with respect to the bottom surface. Specifically, the bent portion 201 is bent so that the lower side is convex. And in the bending shape part 201, the drain hole 202 opened from the inner side to the outer side of the exterior part 200 is formed.

The bent shape portion 201 is provided at a position along a side surface facing the moving body 1 in the left-right direction H1 in a top view (see FIG. 3), and a part of the bent shape portion 201 overlaps with the front side end portion of the front wheel 6a. Yes. The exterior portion 200 that covers the upper unit 3 has a shape protruding outward from the lower unit 2 in a top view. And the bending shape part 201 is provided in the area | region outside the lower unit 2 in the top view. In the present embodiment, the bent shape portion 201 is disposed outside the lower unit 2 in the left-right direction H1.

FIG. 13 is an enlarged top view showing the bent portion 201 viewed from the inside of the exterior portion 200 in the thirteenth embodiment. 14 is an enlarged cross-sectional view taken along the line AA shown in FIG.

The bent shape portion 201 is predetermined with respect to the first surface portion 203 and the first surface portion 203 that are inclined downward as the distance from the hinge portion 4 increases in a state where the upper unit 3 provided with the exterior portion 200 is closed. The second surface portion 204 extends from the lower end of the first surface portion 203 at a predetermined angle. Specifically, the second surface portion 204 is extended from the front side of the first surface portion 203. A horizontal auxiliary line LH shown in FIG. 14 indicates a straight line parallel to the horizontal direction H. In the present embodiment, the angle at which the first surface portion 203 is inclined with respect to the horizontal direction H (first surface angle AN1) is a predetermined angle (this is the case when the upper unit 3 provided with the exterior portion 200 is closed). In the example, it is about 45 degrees). Further, the second surface portion 204 is parallel or substantially parallel to the horizontal direction H in a state where the upper unit 3 provided with the exterior portion 200 is closed. The first surface portion 203 and the second surface portion 204 are integrally formed. Note that the portion where the first surface portion 203 and the second surface portion 204 are connected (the apex of the bent shape portion 201) is rounded (curved) so that the inclination gradually changes.

The drain hole 202 is provided in a connection portion between the first surface portion 203 and the second surface portion 204. Specifically, the drain hole 202 is provided so as to include the apex of the inclination in the bent shape portion 201. The drain hole 202 is formed from the end of the first surface 203 on the second surface 204 side to the end of the second surface 204 on the first surface 203 side. The drain holes 202 are elongated holes in the front-rear direction H2, and a plurality of drain holes 202 are provided apart from each other in the left-right direction H1.

The first surface portion 203 is inclined so that water flows toward the drain hole 202 in a state where the upper unit 3 provided with the exterior portion 200 is closed. Therefore, the water flowing downward through the first surface portion 203 can be reliably discharged from the drain hole 202.

In the state where the upper unit 3 provided with the exterior part 200 is closed, the second surface part 204 including the drain hole 202 constitutes the lowest point in the bent shape part 201. Thereby, the flowing water guided through the second surface portion 204 can be discharged to the outside from the drain hole 202. Moreover, even if water has accumulated on the front side of the drain hole 202 in the second surface portion 204, the movable body 1 moves to the opposite side of the traveling direction D due to inertial force when accelerating in the traveling direction D. Water can be discharged from the drain hole 202 to the outside.

In this example, water may flow toward the lower unit 2 from both sides (specifically both end portions) in the left-right direction H1 on the front side (specifically, the front end portion) of the exterior portion 200 of the upper unit 3. For this reason, a drain hole 202 is provided behind the both-end component 15. By doing so, it is possible to effectively prevent water from entering from the exterior portion 200 of the both-end component 15 in the upper unit 3 into the exterior portion 200 of the lower unit 2.

In the present embodiment, a partition (not shown) is provided behind the first surface portion 203 and the first surface portion 203 so as to prevent water from flowing back and forth between the first surface portion 203 and the first surface portion 203. The side is partitioned. However, the present invention is not limited to this, and a structure may be employed in which water is discharged by opening the rear side of the bottom surface of the exterior portion 200 from the first surface portion 203 (in this example, the portion positioned above the front wheel 6a).

The first surface portion 203 is located above the front wheel 6a (see, for example, FIG. 1) and has a curved surface along the shape of the front wheel 6a at the upper end. The shape of the first surface portion 203 is not limited to this, but may be a curved surface that is curved so that the upper side is convex along the front wheel 6a. By carrying out like this, the distance between the bending shape part 210 and the wheel 6 can be narrowed, and the miniaturization of the mobile body 1 can be realized.

FIG. 15 is an enlarged cross-sectional view showing a cross section in the vicinity of the drain hole 202 with the exterior portion 200 opened.

FIG. 15 shows a state in which the upper unit 3 provided with the exterior part 200 is opened with respect to the state shown in FIG. An opening angle AN2 shown in FIG. 15 indicates an angle at which the upper unit 3 provided with the exterior part 200 is opened with respect to the lower unit 2, and is set to about 40 degrees, like the opening angle θa shown in FIG. Yes. In the state where the upper unit 3 provided with the exterior part 200 is opened, the portion of the drainage hole 202 in the bent shape part 201 includes the lowest point.

Specifically, the first surface angle AN1 is set larger than the opening angle AN2. Then, in the first surface portion 203, the first surface portion 203 is inclined so that the drain hole 202 is located downward even when the upper unit 3 provided with the exterior portion 200 is opened. On the other hand, in the 2nd surface part 204, the direction of the 2nd surface part 204 changes so that the back side of the 2nd surface part 204 may become downward, and when it does so, the drain hole 202 will be located below. As a result, even when the upper unit 3 provided with the exterior part 200 is opened, the water accumulated in the bent shape part 201 on the front side and the rear side from the drain hole 202 is guided toward the drain hole 202. The In this way, by setting the first surface angle AN1 to be larger than the opening angle AN2, even when the upper unit 3 provided with the exterior portion 200 is opened, the drain hole 202 is at the bottom of the bent shape portion 201. Contains a point. Therefore, flowing water can be reliably induced.

Thus, in the drainage structure 100 of the exterior part 200, regardless of whether the upper unit 3 provided with the exterior part 200 is opened or closed (whether the upper unit 3 is closed or open), A region corresponding to the drain hole 202 in the bent shape portion 201 includes the lowest point.

According to the drainage structure 100 of the exterior part 200 described above, the drainage hole 202 can be provided at a location where the flow of flowing water is concentrated even when the upper unit 3 provided with the exterior part 200 is opened or closed. it can. Thereby, it can suppress that the water which flowed in from the outside, such as rain water, accumulates. Moreover, the drainage hole 202 can be provided and the location which drains can be specified. Thereby, when the upper unit 3 provided with the exterior part 200 is opened, it is possible to prevent water from falling into the moving body 1 due to an unintended flow of flowing water.

In the present embodiment, the bent shape portion 201 having the drain hole 202 is provided on the front side of the front wheel 6a. However, the present invention is not limited to this, and water is not provided on the front side of the rear wheel 6b or the rear end of the exterior portion 200. A bent shape portion 201 having a punched hole 202 may be provided. Moreover, when the position which provides the hinge part 4 is changed, according to it, the position which provides the bending shape part 201 which has the drain hole 202 can be changed suitably.

Further, in the present embodiment, the drain hole 202 is provided at a position that does not overlap the lower unit 2 when viewed from above, so that the discharged water can be prevented from falling to the lower unit 2.

By the way, if the drain hole 202 is made too large, it will be effective for drainage, but the support structure of the exterior part 200 tends to become fragile, so that the strength becomes uneasy. In addition, if there is a large drainage hole 202, an unintended object may enter the moving body 1 (for example, a user inserts a finger into the moving body 1), which may cause a secondary inconvenience. . Therefore, the drainage hole 202 has a length in the front-rear direction H2 and a width in the left-right direction H1, which is a support structure of the exterior part 200 that includes the lowest point of the bent shape part 201 and has an allowable strength. It is possible to reduce the size so that an object that is not to enter into the moving body 1 is difficult to enter. Thereby, it is possible to prevent an unintended object from entering the interior while maintaining the strength of the exterior part 200.

In the present embodiment, the drain hole 202 has a width in the front-rear direction H2 of a predetermined distance (in this example, about 16 mm), and a width in the left-right direction H1 is set to a predetermined distance (in this example, about 5 mm). Here, the drain hole 202 is set so that the longitudinal direction (front-rear direction H2) is the traveling direction D, and the width in the longitudinal direction is the curved portion of the bent shape portion 201 (the first surface portion 203 and the second portion). The length includes all of the connection portions to the surface portion 204).

Next, a mobile unit according to a fourteenth embodiment of the present invention is described with reference to FIG. Note that the fourteenth embodiment has a schematic structure substantially the same as that of the thirteenth embodiment, so the same reference numerals are used and description thereof is omitted.

FIG. 16 is an enlarged top view showing the bent portion 201 viewed from the inside of the exterior portion in the fourteenth embodiment.

The fourteenth embodiment differs from the thirteenth embodiment in that a guide portion 205 is provided near (adjacent to) the drain hole 202.

Specifically, the bent shape portion 201 is provided with a guide portion 205 that guides water toward the drain hole 202. The guide part 205 is a step. The guide portion 205 is higher on the front side and / or the rear side than the center portion in the front-rear direction H2 of the drain hole 202 and lower on the front side and / or rear side than the drain hole 202 side. It is provided on the upper surface of the bent portion 201 so as to be.

Specifically, the guide part 205 is a convex part that is extended so as to be connected to the drain hole 202. In the present embodiment, the guide portion 205 is a rib formed so as to protrude from the upper surface of the bent shape portion 201. Further, the guide portion 205 is provided at four locations around each drain hole 202. In this example, the guide portion 205 is provided at a position (specifically, at the four corners or in the vicinity of the four corners) connected to the front left and right end portions and the rear left and right end portions with respect to the drain hole 202. Yes. The guide part 205 communicates with the end opposite to the side connected to the drain hole 202 of the other adjacent guide part 205 at the end opposite to the side connected to the drain hole 202. Yes. Adjacent and adjacent guide portions 205 and 205 are formed so as to gradually approach toward the water drain hole 202 located between the adjacent guide portions 205 and 205. The connecting portion between the adjacent guide portions 205 and 205 is located at the center portion or the substantially center portion between the adjacent drain holes 202 and 202. The guide part 205 is linearly extended in a direction inclined with respect to the front-rear direction H2 and the left-right direction H1. In addition, the guide part 205 may be extended | stretched curvilinearly (so that it may curve in a concave shape or convex shape with respect to the front-back direction H2.). That is, one of the adjacent guide portions 205, 205 may be concavely curved with respect to the front-rear direction H2, and the other may be convexly curved, or both may be curved concavely or convexly. May be.

In the drainage structure 100 of the exterior part 200 described above, when the water flowing along the first surface part 203 and the second surface part 204 reaches the guide part 205, it follows the guide part 205 as indicated by an arrow C in FIG. Guided in the direction. Therefore, it is possible to suppress the retention of water in the portion where the drain hole 202 of the bent shape portion 201 does not exist (specifically, the portion between the adjacent drain holes 202, 202). It can be drained.

In the present embodiment, the guide portion 205 is a rib protruding from the upper surface of the bent shape portion 201. However, the present invention is not limited to this, and the guide portion 205 may be a groove recessed on the upper surface of the bent shape portion 201. When the guide part 205 is a groove, the water that has reached the guide part 205 once enters the guide part 205 and is guided to the drain hole 202 through the guide part 205.

(Fifteenth embodiment)
Next, the moving body 1 according to a fifteenth embodiment of the present invention will be described with reference to FIGS. 17 and 18. Note that the fifteenth embodiment has a schematic structure substantially the same as that of the thirteenth and fourteenth embodiments, so the same reference numerals are used and description thereof is omitted.

FIG. 17 is an enlarged cross-sectional view showing a cross section near the drain hole 202 in the fifteenth embodiment, and FIG. 18 shows a state in which the upper unit 3 provided with the exterior portion 200 is opened in the fifteenth embodiment. It is an expanded sectional view which shows the cross section of the water drain hole 202 vicinity.

FIG. 17 shows a cross section along the front-rear direction H2 as in FIG. The fifteenth embodiment is different from the thirteenth embodiment and the fourteenth embodiment in that the second surface portion 204 is inclined when the upper unit 3 provided with the exterior portion 200 is closed.

Specifically, the second surface portion 204 is inclined downward toward the drain hole 202 in a state where the upper unit 3 provided with the exterior portion 200 is closed. In the present embodiment, the angle at which the second surface portion 204 is inclined with respect to the horizontal direction H (second surface angle AN3) is about 10 degrees in the state where the upper unit 3 provided with the exterior portion 200 is closed (or About 10 degrees).

In the drainage structure 100 of the exterior part 200 described above, the second surface part 204 is inclined downward toward the drain hole 202 in a state where the upper unit 3 provided with the exterior part 200 is closed. By doing so, the water flowing downward along the second surface portion 204 can be made to flow toward the drain hole 202, and thus the water can be reliably discharged from the drain hole 202.

When the opening angle AN2 (θa) is smaller than 90 degrees, the inclination angle (second surface angle AN3) of the second surface portion 204 is set smaller than the value obtained by subtracting the opening angle AN2 (θa) from 90 degrees ( AN3 <90 degrees-AN2). By doing so, the inclination angle (second surface angle AN3) of the second surface portion 204 can be maintained at an angle smaller than 90 degrees even when the upper unit 3 provided with the exterior portion 200 is opened. From this, the second surface portion 204 can be inclined downward toward the drain hole 202, and a structure in which drainage concentrates in the drain hole 202 can be maintained as in the thirteenth embodiment.
