Description

[Detailed Description of the Invention] (Field of Industrial Application) The present invention relates to an improvement of a battery support device for an automobile.

(Prior Art) Batteries for automobiles, especially batteries for electric vehicles, have a large capacity and are large in size, but they also need to be taken in and out of the car body relatively frequently for charging. For this reason, conventionally, as shown in Japanese Utility Model Application Publication No. 50-52633, a battery storage part is provided in the car body, in which the battery can be taken in and out from the side of the car body, while a wheel is placed on the contact surface between the battery and the battery storage part. It has been proposed to provide a battery so that the battery can be smoothly taken in and out of the battery storage section.

By the way, in order to pull out the battery stored in the battery storage section, it is first necessary to grasp the outer end of the battery. Because the gap between the battery compartment and the wall of the battery storage unit or the gap between multiple batteries stored in parallel with each other is small, it is not possible to sufficiently grasp the end of the battery to pull it out. A problem has arisen in that the initial withdrawal process becomes quite troublesome.

(Purpose of the invention) The present invention was made in consideration of the above-mentioned circumstances, and it is an object of the present invention to provide a battery support device for an automobile that allows the battery to be easily pulled out from the battery storage portion.

(Structure of the Invention) In order to achieve the above-mentioned object, in the present invention, a type of lever action by the clamp arm is utilized to pull out the battery from the battery storage portion.

Specifically, the clamp arm is formed into a substantially L-shape having a first arm and a second arm, and a corner portion where the first and second arms are connected is connected to the vehicle of the battery storage section. It is rotatably supported at the lower end on the inside of the body. The tip of the first arm has a contact portion that comes into contact with the inner end of the battery, while the tip of the second arm has a clamp that is engaged with the upper end of the battery on the outer side of the vehicle body. The battery is fixed to the bar by a tightening member in the stored state.

With this configuration, when storing the battery, the tightening force of the tightening member allows
The battery is clamped and fixed between the clamp bar and the first arm tip of the clamp arm. Also, when pulling out the battery, after releasing the tightening by the tightening member and removing the clamp bar, if you grasp the tip of the second arm of the clamp arm and push it down, the tip of the first arm will move toward the outside of the vehicle body. Therefore, the battery is pulled out to the outside of the vehicle body by this displacement.

(Embodiment) In FIG. 1, reference numeral 1 denotes a truck as an electric vehicle, and a battery storage section 2 is provided below a loading platform 1a. This battery storage part 2
As shown in FIG. 2, by bending an iron plate or the like, it has a bottom wall 2a and left and right side walls 2b. As shown in FIGS. 1 and 3, a plurality of batteries 3 (three in the embodiment) are stored in this battery storage section 2 in parallel with each other.
The loading and unloading is carried out in the direction of the arrow in FIG. 2, that is, from the lateral side of the truck 1 (direction perpendicular to the plane of the paper in FIG. 1).

4 in Figure 2 is the clamp arm, which is the third
As shown in FIGS. 5 to 5, the first arm 4a and the second
By integrating the arm 4b with the arm 4b by welding or the like, the overall shape is approximately L-shaped. This clamp arm 4 has both first and second arms 4.
A corner portion 4c, which is a connecting portion between a and 4b, is rotatably connected by a pin 6 to a bracket 5 welded to the lower end of the battery storage portion 2 on the inside side of the vehicle body. A first arm 4a of the clamp arm 4 extends upward from the corner portion 4c.
A bracket 7 is fixed to the tip of the bracket 7, and a roller 8 is rotatably attached to the bracket 7 by a pin 9. Further, a screw shaft 10 is fixed by welding or the like to the tip of the second arm 4b that extends outward from the corner portion 4c of the vehicle body. As will be described later, this screw shaft 10 serves both as a fixing function when fixing the battery 3 and as a grip when pulling out the battery 3 from the battery storage section. The length of the second arm 4b is set to reach the vicinity of the upper end of the battery 3 on the outside of the vehicle body in the storage position.
The screw shaft 10 extends further outward from the vehicle body than the upper end of the battery 3 on the vehicle body outer side.

In the embodiment, two clamp arms 4 as described above are provided, and the second arms 4b are positioned in the gaps between the batteries 3 arranged in parallel with each other. In addition, the first arm 4a and the second
The arm 4b forms an angle smaller than 90 degrees, so that when the screw shaft 10 is located near the upper end of the battery 3 on the outside of the vehicle body, the first arm 4a extends almost straight in the vertical direction. The roller 8 is brought into contact with the back surface of the battery holder 11 which is engaged with the upper end of the battery 3 on the inside side of the vehicle body.

In order to fix the battery 3, a clamp bar 12 having a substantially L-shaped cross section is engaged with its upper end on the outer side of the vehicle body. This clamp bar 12 has a length that is approximately the same as the full width of the three batteries 3 arranged in parallel with each other, and a screw shaft 10 passes through the clamp bar 12 as shown in FIG. A through hole 12a is opened. A nut 14 is screwed into the screw shaft 10 passing through the through hole 12a via the boss 13, and by tightening the nut 14, the battery 3 is tightened via the boss 13 and the clamp bar 12.
will be pressed against the roller 8. In this way, the battery 3 is clamped and fixed between the tip of the first arm 4a (roller 8) and the tip of the second arm (nut 14) of the clamp arm 4 without rattling. In addition, when this is fixed, the end surface of the battery 3 (battery storage part 2) on the outside of the vehicle body is covered with a cover 16 rotatably attached to the loading platform 1a with a pin 15, as shown in FIG. It's getting old.

To pull out the battery 3 stored and fixed in the battery storage section 2 using the nut 14 or the like as described above, first open the cover 16 by rotating it as shown by arrow A in FIG. In this state, after loosening the nut 14 and releasing at least the engagement of the clamp bar 12 with the battery 3, the screw shaft 10 is
All you have to do is hold it and push it down as shown by arrow B in Figure 5. By pushing down this screw shaft 10,
As a result of the clamp arm 4 being rotationally displaced as shown by the dashed line in FIG. As a result, the battery 3 is pulled out from its fixed position as indicated by arrow C in FIG. 5 to the outside of the vehicle body by a length l as indicated by a chain line in FIG. This length l
By pulling out the battery 3, a large space is created around the outer edge of the battery 3, which allows you to firmly grasp this edge, so you can easily remove the battery 3 from now on. It can be pulled out. In addition, when pulling out the battery using the clamp arm 4, by using the roller 8,
The battery 3 can be pressed smoothly.

Here, when replenishing battery fluid, replacing the battery, etc., it is sufficient to completely pull out the battery 3 from the battery storage section 2, but when simply charging the battery, etc.
By locating the battery side connector for charging on the outside of the vehicle body, charging can be performed while the battery is in the extended state of the length l.

FIGS. 7 and 8 show another embodiment of the present invention, and the same components as those in the previous embodiment are given the same reference numerals and their explanations will be omitted. In this embodiment, an explosion-proof center plate 1 is placed between the batteries 3.
7 is interposed therebetween, and an abutting plate 17a, on which the roller 8 abuts, is integrated with the end surface of the center plate 17 on the inner side of the vehicle body. Of course, when pulling out the battery 3 using the clamp arm 14, the roller 8 pulls out the battery 3 via the contact plate 17a.
This is to push the outside of the vehicle body.

(Effects of the invention) As is clear from the above, the invention has the following effects:
The battery can be easily pulled out from the battery storage section using the clamp arm. Furthermore, since the battery is fixed using the clamp arm, it is possible to prevent the battery from rattling due to vibrations during driving.
