【Example】

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the drawings.

0012 1 and 2, reference numeral 10 is an automatic guided vehicle to which the present invention is applied. A battery storage section 12 is formed in the vehicle body 11 of the automatic guided vehicle 10. . The left and right vehicle body side walls 13 of the battery storage section 12 are open, and these open portions This is a battery exchange port 14. In addition, a battery is provided on the bottom of the battery storage section 12. A plurality of rollers 15 are arranged in parallel to facilitate the loading and unloading of the tissue.

[0013] The battery 16 is stored in the battery case 17 in the battery storage section 12. will be stored in. Battery side electrode terminals 18 are provided at both ends of the upper part of the battery case 17. It is provided. A pin hole 19 is vertically bored in each battery side electrode terminal 18. ing.

[0014] This pin hole 19 of the battery side electrode terminal 18 has a stock provided on the vehicle body 11. Papin 20 is inserted and removed. Each stopper pin 20, as shown in FIG. When the battery case 17 is placed in the predetermined position in the battery storage section 12, the corresponding battery It is arranged coaxially with the pin hole 19 of the battery side electrode terminal 18. Also, Each stopper pin 20 is supported by a movable bracket 2 that is vertically movably supported within the vehicle body 11. 1, and is moved up and down by a suitable drive means 22 to the corresponding battery side. It is inserted into and removed from the pin hole 19 of the electrode terminal 18.

[0015] Various driving means 22 for the stopper pin 20 can be considered, but in this embodiment, A female threaded portion 23 integrally formed on the movable bracket 21 and a female threaded portion 23 are integrally formed on the movable bracket 21. 23 and a screw body 24 extending vertically, and a screw body 24 integrally attached to the upper end of the screw body 24. a first bevel gear 25 attached to A shaft 26 is integrally attached to the shaft 26 and meshes with the first bevel gear 25. and a second bevel gear 27 that fits together. The shaft 26 has left and right It is shared by the stopper pin drive means 22, and the shaft 26 is rotated. With this, the left and right stopper pins 20 can be moved up and down simultaneously. shaft 2 6 is provided with an operating means for operating the stopper pin driving means 22. A working handle 28 is provided. Opposed to each operation handle 28 on the side wall 13 of the vehicle body An opening 29 is provided in the part where the operator handles the operation. 28 can be turned.

[0016] Further, the stopper pin 20 is inserted into the pin hole 19 of the battery side electrode terminal 18. The tip end is made of a conductor and is connected to the electric/electronic circuit inside the vehicle body 11. It serves as an electrode terminal 30, and when the stopper pin 20 is inserted into the pin hole 19, both Electrode terminals 18 and 30 are electrically connected. Note that the other parts of the stopper pin 20 are Preferably, it is made of a nonconductor such as lamic.

[0017] In such a configuration, a case where the battery 16 is replaced will be described. Book In the design, the battery 16 is replaced using the same procedure from either the left or right side. Therefore, only the work on the right side of the vehicle body 11 will be explained here. Ru.

[0018] First, the operator accesses the internal operation handle 28 from the opening 29 in the right side wall 13 of the vehicle body. in the specified direction, and as mentioned above, remove both the left and right stopper pins 20 from the battery. Pull it out from the pin hole 19 of the side electrode terminal 18. As a result, the battery case 17 is At the same time, the battery 16 is disconnected from the vehicle body electric circuit and the like. After this, if you hold the handle 31 provided on the end face of the battery case 17 and pull it, The battery case 17 slides on the rollers 15 of the battery storage section 12 while moving toward the vehicle body side. It passes through the battery exchange port 14 in the wall 13 and onto the battery carrier 32 . this The battery case 17 placed on the battery carrier 32 in this manner carries the battery. It is transported to a replacement station and the battery 16 inside is replaced.

[0019] The battery case 17 containing the new battery 16 is attached to the battery carrier 32 After being placed on the right side of the automatic guided vehicle 10 again, the battery replacement on the side wall 13 of the vehicle body is It is pushed into the battery storage part 12 from the exchange port 14. At this time, the stock is removed from the opening 29. Since the pin 20 and the battery side electrode terminal 18 are visible, the position of the battery case 17 is You can check the location. Once the battery case 17 is placed in the predetermined position , turn the operating handle 28 in the opposite direction to the above, and move each stopper pin 20 to the corresponding bar. Insert into the pin hole 19 of the battery side electrode terminal 18. Stopper pin 20 is in pin hole 19 When the battery case 17 is fully inserted into the vehicle body 11, the battery case 17 is fixed to the vehicle body 11 and Then, power supply from the battery 16 to the vehicle body side is started.

[0020] In the above embodiment, the battery side electrode terminals 18 are symmetrical to both ends of the battery case 17. Since the battery case 17 is arranged vertically, there is a risk that the battery case 17 may be inserted backwards. Therefore, As shown in FIG. 2, a protrusion 33 is provided on one side of the battery case 17. is preferable.

[0021] Moreover, the battery side electrode terminals 18 are not provided at both ends of the battery case 17, but at one end. They may be arranged in parallel at one end of the battery case 17, or on the side or bottom of the battery case 17. It is also possible to provide one.

[0022] Furthermore, in the above embodiment, the stopper pin driving means is composed of a gear mechanism. , other means such as a link mechanism are also conceivable.

[0023]

[Effect of the idea]

As described above, according to the present invention, the battery can be replaced from both sides of the vehicle body. Therefore, positional constraints on battery replacement work are alleviated. For example, on one side Even if an unmanned vehicle stops in a place where there is an obstacle, the battery cannot be replaced at that location. I can do that.

[0024] Also, at the same time as unlocking the battery case, the battery and the vehicle side Since the electronic circuits etc. are separated, battery replacement work can be simplified. Ru.
