More specifically, the length between the pair of ribs 71e on both sides in the width direction of the chair is set to be shorter than the length in the width direction of the chair in the cover member 73 described later.
For this reason, the cover member 73 that covers the ECU 7 and is held by the holding cover 71 is restricted from moving forward by the rib 71e.

Between the ribs 71d adjacent to each other in the front-rear direction provided on the side surface of the holding cover 71, a rectangular slit 71h extending vertically is formed. Note that slits 71 h are also formed on the rear surface of the holding cover 71 at similar intervals.
Thus, by forming the slit 71h, air can flow between the inside and the outside of the holding cover 71, and the heat dissipation of the ECU 7 and the battery 8 held by the holding cover 71 can be improved.
In particular, the slit 71h formed on the rear surface of the holding cover 71 causes the air sent from the fan 50 in front of the holding cover 71 to flow backward, improving heat dissipation.
In addition, you may make it function a part of slit 71h as a through-hole of the charging cable which is not shown in figure, or the harness 11 or the harness U8 instead of the opening 71i.

The base member 72 and the cover member 73 are frames having a substantially U-shaped vertical cross section.
Specifically, the base member 72 has a substantially U-shaped cross section, and extends in the front-rear direction longer than the width direction length. A plurality of punch holes 72a are formed on the side surface of the base member 72, and the heat dissipation of the ECU 7 supported therein is enhanced by allowing air to flow.
On the other hand, the cover member 73 has a substantially U-shaped cross section and extends in the width direction longer than the length in the front-rear direction.
In particular, a rectangular notch is formed on the front surface of the cover member 73 in order to expose the connector 70 of the ECU 7 and connect the ECU 7 to the respiration sensor 9 or the vibration device 35 by the connector 70.
These are stacked one above the other to form a storage space for the ECU 7.
The base member 72 and the cover member 73 are fastened by the fixing screw N2 in a state where the ECU 7 is stored, stacked on the battery 8, and held in the housing concave groove 71a.

The base member 72 is placed on the ribs 71d that are arranged at intervals in the front-rear direction, so that the heated air generated from the ECU 7 passes between the ribs 71d via the punch holes 72a of the base member 72. Will pass. For this reason, the heat dissipation of ECU7 can be made favorable.
Furthermore, since the lower part of the rib 71d is formed with a height higher than the thickness of the battery 8 in the vertical direction, the holding cover 71 and the battery 8 arranged on the rib 71d can be separated from each other.
As described above, the holding cover 71 and the battery 8 are arranged apart from each other, so that the heat between the two can be prevented from being directly transmitted and the temperature rise between the two can be suppressed.

  The control device U <b> 1 is stored together with the battery 8 in the housing groove 71 a of the holding cover 71. In this state, the holding cover 71 is fastened to the cushion pan F21 by the tapping screw N1.

  In particular, the holding cover 71 is attached to the upper frame portion F21c in front of the lower frame portion F21b and below the resin plate F21d, and the space in front of the lower frame portion F21b is effectively utilized. . By attaching the holding cover 71 in this way, it is possible to suppress the downward extension of the resin plate F21d and to prevent the seating area for the seated person from being narrowed.

<About the seat cover that covers the resin plate>
In the said embodiment, the holding | maintenance cover 71 was demonstrated as what hold | maintains and protects the control apparatus U1 and the battery 8. FIG. Further, in order to enhance the protection capability and improve the aesthetic appearance, a seat cover 51 that covers the resin plate F21d together with the holding cover 71 may be attached.

Next, the seat cover 51 that covers the resin plate F21d from the back surface will be described with reference to FIGS. 8 to 11 in addition to FIG.
Here, FIG. 8 is a schematic front view showing a state in which the seat cover 51 is attached to the lower surface of the resin plate F21d. FIG. 9 shows the control device holding cover 77 and the battery holding cover 78 on the lower surface of the resin plate F21d. 10 is a schematic front view showing the attached state, FIG. 10 is an upper perspective view showing the upper part of the seat cover 51, and FIG. 11 is a schematic side view showing the seat cover 51 from the side.

  The seat cover 51 is made of a resin material and has a bowl shape. The seat cover 51 has a slit 51a in the upper front portion, an elongated hole 51c that exposes the battery 8 in the lower portion of the front surface, and an exhaust port 51b (see FIG. 3) on the rear surface.

The slit 51a is for introducing outside air into the seat cover 51 in order to air-cool the control device U1 and the battery 8, and extends in the width direction of the chair and is formed in two vertically.
Then, as shown in FIG. 3, the fan 50 is disposed at a position facing the slit 51a, so that the intake of outside air is further promoted.

The opening 51c exposes the battery 8 and allows the battery 8 to be taken in and out or connected between a charging cable (not shown) and the charging jack 80a while the holding cover 71 is covered with the seat cover 51. is there. The opening 51c penetrates in the front-rear direction and extends in the width direction of the chair below the slit 51a. The opening 51c functions as an outside air intake port together with the slit 51a.
Furthermore, you may make it function the slit 51a or the opening 51c as a through-hole of the charging cable which is not shown in figure, the harness 11, or the harness U8.
The seat cover 51 only needs to be attached to the resin plate F21d in such a direction that the opening 51c does not face the support column F21a that obstructs the insertion and removal of the battery 8 or the like. That is, if the opening 51c is not oriented to face the support column F21a, the seat cover 51 may be attached so that the opening 51c is directed not only to the front but also to the side and rear.

The exhaust port 51 b is for exhausting the air taken in from the slit 51 a or the opening 51 c to the outside of the seat cover 51.
As described above, the heat of the ECU 7 and the battery 8 can be dissipated by exhausting the air taken in from the slit 51a or the opening 51c and passing through the ECU 7 or the battery 8 to the outside of the seat cover 51. It becomes possible.

Further, the holding cover 71 according to the above embodiment is configured to hold the control device U1 and the battery 8 together in the vertical direction, but a cover that holds them separately may be adopted.
For example, as shown in FIG. 9, a control device holding cover 77 that holds the control device U1 and a battery holding cover 78 that holds the battery 8 may be mounted side by side in the width direction of the chair.
Since the control device holding cover 77 and the battery holding cover 78 are attached in this way, both covers below the resin plate F21d rather than the holding cover 71 that holds the control device U1 and the battery 8 in a stacked manner vertically. Can be suppressed. Along with this, the downward extension of the seat cover 53 covering them can also be suppressed.

In the seat cover 51 and the seat cover 53, a recess is formed in a portion facing the holding cover 71 or the control device holding cover 77 and the battery holding cover 78.
For example, as shown in FIG. 10, as a recess in the seat cover 53, a control device housing portion 53 a is formed at a portion facing the control device holding cover 77, and a battery housing portion 53 b is formed at a portion facing the battery holding cover 78. In addition, a plurality of ribs 53c are formed at other portions. The seat cover 53 is light and has high rigidity due to the formation of a plurality of ribs 53c.

The control device housing portion 53 a has a shape corresponding to the control device holding cover 77, and the battery housing portion 53 b has a shape corresponding to the battery holding cover 78.
Specifically, as in the present embodiment, when the lower surface of the control device holding cover 77 is at a lower position than the lower surface of the battery holding cover 78, the control device housing portion 53a is more than the battery housing portion 53b. Deeply formed.
The control device housing portion 53a is formed such that the bottom surface of the control device housing portion 53a is positioned slightly lower than the lower surface of the control device holding cover 77 in a state where the seat cover 53 is attached to the resin plate F21d. Has been.
Similarly, the battery housing portion 53b is formed such that the bottom surface of the battery housing portion 53b is positioned slightly lower than the lower surface of the battery holding cover 78 in a state where the seat cover 53 is attached to the resin plate F21d. Yes.

Since the control device housing portion 53a and the battery housing portion 53b are formed in this manner, the resin plate F21d is not obstructed by the resin plate F21d with the control device holding cover 77 and the battery holding cover 78 attached thereto. The seat cover 53 can be attached to F21d.
In this case, since the control device accommodating portion 53a is formed deepest than the other portions, the amount of the downward protrusion of the seat cover 53 can be minimized, and the control device accommodating portion 53a is below the seat cover 53. A place for seated legs can be widened.

Similarly to the seat cover 53 having the control device housing portion 53a for housing the control device holding cover 77 and the battery housing portion 53b for housing the battery holding cover 78 and including the ribs 53c, the seat cover 51 is also provided. A recess (not shown) that covers the holding cover 71 and a rib can be formed.
In this case, it is preferable that the holding cover 71, in other words, the concave portion (not shown) is arranged at the center in the width direction of the chair. According to such a configuration, the weight in the width direction of the chair can be balanced.

  Furthermore, when the control device U1 or the battery 8 is attached to the back pan F22 side, the same configuration as the seat cover 51, 53 described above can be applied to the back cover 55.

(About the display provided on the seat cover)
An operation switch U5, an operation display unit U6, and a charging state display unit U7 are attached to the side surface of the seat cover 51 shown in FIG.

  The operation switch U5 is a push button type operation switch for actuating or stopping the awakening device U, and is fitted into a fitting hole (not shown) of the seat cover 51.

  The operation display unit U6 is a display lamp that indicates that the awakening device U is operating or stopped. When the operation display unit U6 is operating normally, the operation display unit U6 displays blue and is operating but has some trouble. It is configured to display yellow when it is present and to turn off when it is stopped.

The charging state display unit U7 is a display lamp that displays the charging state of the battery 8. When the battery 8 is sufficiently charged, the charging state display unit U7 displays blue, and when the remaining charge becomes a predetermined value or less. Is displayed in red, and is turned off when the remaining charge is exhausted.
As shown in FIG. 11, the operation display unit U6 and the charging state display unit U7 are attached to the side surface of the seat cover 51, and are arranged at positions sandwiching the operation switch U5.

Thus, by attaching the operation switch U5, the seated person can operate with the awakening function sitting on and off, and the operability is improved.
Moreover, since the operation display part U6 and the charge state display part U7 are provided, since the operation state of the awakening function and the charge state of the battery 8 can be confirmed, it becomes easy to use.

  Note that the operation switch U5, the operation display unit U6, and the charge state display unit U7 may be fitted into a fitting hole (not shown) provided in the upper end portion of the backrest cover 55 as shown in FIG. Well, it may be attached to both covers.

<Modification>
Finally, with reference to FIG. 12, a seat cover 54 according to a modification will be described.
Here, FIG. 12 is a schematic cross-sectional view showing a III-III cross section of FIG. 1 showing a seat cover 54 according to a modification.

The seat cover 54 according to the modification is formed and attached so as to cover only the front side of the support column F21a on the lower surface of the resin plate F21d.
A through hole 54a for exposing the charging jack 80a of the battery 8 shown in FIG. 5 is formed at a position facing the support column F21a on the rear surface of the seat cover 54.
The battery 8 is held by the holding cover 71 so that the charging jack 80a faces rearward facing the support column F21a. The holding cover 71 has a through hole 75a that exposes the charging jack 80a at the rear. ing.

Further, a through hole F21n communicating with the outside and the internal space is formed on the front side of the support column F21a facing the seat cover 54.
That is, in the state where the seat cover 54 covers the holding cover 71, the through hole 54a, the through hole 75a, and the through hole F21n face each other, and the extension cable 66 is passed through the inside of the support column F21a through these. Yes.

As shown in FIG. 1, a charging connector 65 is disposed at the tip of a foot F31 above the caster F31a in the leg member F3.
An extension cable 66 is connected to the charging jack 80a and the charging connector 65.
With such a configuration, the charging cable 65 can be charged by inserting the charging cable into the charging connector 65 located at the tip of the foot F31 close to the floor, so that the charging cable does not interfere with the person passing through the periphery. It will be easy to use.
Further, the seated person can more easily see the tip of the foot F31 than the vicinity of the lower surface of the cushion pan F21, and can easily connect a charging cable (not shown) to the charging connector 65.

Similarly to the through hole 75a for passing the extension cable 66, a harness (not shown) connected to the harness 11 and the vibration device 35 is attached to the rear surface of the seat cover 54 and facing the support column F21a. You may make it form the through-hole for letting it pass to back of.
As described above, since the through hole is formed at the position facing the support column F21a, it is possible to make it difficult for the seated person to touch the harness connection portion that is less likely to be touched except for maintenance.
In this modified example, the seat cover 54 is naturally an optional component.

  Since the slit 51a or the opening 51c functions as an inlet / outlet of the battery 8, a charging cable (not shown), or a through hole of the harness 11 or the harness U8, the slit 51a or the opening is formed in the support column F21a which becomes an obstacle to the insertion / extraction of the battery 8. It is only necessary that the seat covers 51, 53, and 54 are attached so that the holes 51c do not face each other. That is, if the slit 51a or the opening 51c is not oriented to face the support column F21a, the seat covers 51, 53, and 54 are attached so that the slit 51a or the opening 51c faces not only the front but also the side and the rear. May be.

In the above embodiment, the fan 50 is attached to the lower surface of the resin plate F21d. However, the configuration is not limited to this configuration as long as the ECU 7 or the battery 8 can be cooled.
For example, the fan 50 may be attached to the seat cover 51. The attachment of the fan 50 to the seat cover 51 is effective when the fan 50 cannot be attached because the resin plate F21d is made of metal and is difficult to tapping.
Further, a space for the holding cover 71 may be provided, and the fan 50 may be attached to the space. If the fan 50 is attached to the holding cover 71, the fan 50 is arranged near the ECU 7 connected to the fan 50, so that the wiring can be made compact.
