Description

  The present invention relates to a stopper for regulating the sliding of a battery in a sliding battery that slides on and removes the battery from a vehicle body.

  Battery-powered industrial vehicles (for example, towing vehicles and forklifts) use a battery as a drive source. Therefore, a very large battery is adopted. Since a large battery is heavy, a sliding battery that slides on and off the vehicle body is used. And an industrial vehicle is provided with the stopper which controls the slide of a battery so that the battery accommodated in the vehicle body may not escape from a vehicle body (for example, patent document 1 and patent document 2).

The stopper is changed to a restricting position for restricting the sliding of the battery and an allowable position for allowing the sliding. Then, the stopper is set to the restriction position to prevent the battery from coming out of the vehicle body. Also, with the stopper set to the permissible position, pull out the battery from the vehicle body. Therefore, when replacing the battery, the stopper is moved from the restricted position to the permitted position, pulled out, pushed in, and then moved from the permitted position to the restricted position. Cost. In addition, there is a stopper that can be operated once, but it is necessary to pull out the battery with one hand.

  Therefore, in view of the above circumstances, the problem to be solved by the present invention is that the battery only needs to be operated once when replacing the battery, and the battery can be safely pulled out and pushed in with both hands. It is to provide a battery stopper.

In order to solve the above problems, the stopper according to the present invention is:
A sliding battery stopper,
A regulating member for regulating the sliding of the battery;
A rotating shaft that rotates the restricting member between the first position and the second position;
A lever member for rotating the regulating member;
And a biasing member capable of biasing the restricting member in both the first position and the second position.
The regulating member is
In the first position, the sliding in the battery pull-out direction is restricted, and the battery is allowed to slide in the pushing-in direction,
When in the second position, the battery is allowed to be pulled out and slid in the pushing direction.
The lever member
While the regulating member is changed from the first position to the second position, the regulating member is changed from the second position to the first position by the battery in the process of sliding the battery in the pull-out direction.

Preferably,
A support member for supporting the rotation shaft;
The biasing member consists of a torsion coil spring,
The torsion coil spring has one end attached to the support member and the other end attached to the regulating member.

  Preferably, the restricting member has a notch for locking the slide of the battery.

  According to the present invention, when replacing the battery, the regulating member is moved from the first position to the second position. Since the battery can be pulled out with the biasing member biasing the regulating member to the second position, the operator can pull out the heavy battery with both hands, and there is no danger of pinching the hand. In the process of sliding the battery in the pull-out direction, the battery operates the lever member to change the regulating member from the second position to the first position. For this reason, the operator needs only to operate the stopper once and is less troublesome.

  Hereinafter, a stopper for a sliding battery according to the present invention will be described with reference to the accompanying drawings.

[Stopper arrangement]
FIG. 1 is a side view showing a state in which a battery is pulled out from a tow vehicle. FIG. 2 is a perspective view of the towing vehicle viewed from the rear. In FIG. 1, the towing vehicle 3 is represented by a two-dot chain line.

  As shown in FIG. 1, the towing vehicle 3 detachably stores the battery 2 in a storage portion 30 a at the rear of the vehicle body 30. The towing vehicle 3 travels using the battery 2 as a drive source. The battery 2 is slidable in the front-rear direction 30 b in the storage portion 30 a of the vehicle body 30.

  The towing vehicle 3 includes a stopper 1 in the storage portion 30 a of the vehicle body 30. The stopper 1 restricts backward sliding of the battery 2 in the front-rear direction 30b. That is, when the battery 2 is housed in the housing portion 30 a of the vehicle body 30, sliding forward is restricted by the inner wall 30 c of the housing portion 30 a, and sliding backward is restricted by the stopper 1.

  The towing vehicle 3 includes a cover 31 that can be opened and closed at the rear. When the operator replaces the battery 2 or the like, the battery carrier vehicle 40 is disposed behind the towing vehicle 3, the cover 31 is opened, and the battery 2 is slid in the front-rear direction 30 b, thereby removing the battery from the vehicle body 30. It is pulled out to the transport vehicle 40 or pushed into the vehicle body 30 from the battery transport vehicle 40.

  As shown in FIG. 2, the towing vehicle 3 includes a rail 32 that extends in the front-rear direction 30 b in the storage portion 30 a. The battery 2 slides along the rail 32. As described above, the towing vehicle 3 includes the stopper 1 in the storage portion 30a. Further, the battery 2 includes an auxiliary lock pin 33, and the auxiliary lock pin 33 is inserted into the vehicle body 3 to restrict sliding.

[Configuration of stopper]
FIG. 3 is a view for explaining the configuration of the stopper. 3A is a side view, FIG. 3B is a plan view, FIG. 3C is a rear view, and FIG. 3D is a perspective view seen from the rear.

  The stopper 1 includes a regulating member 11. The regulating member 11 is a plate member. The restricting member 11 has a notch portion 11a at the front portion in the front-rear direction 30b. As will be described later, the notch 11a of the restricting member 11 locks the battery 2 to restrict the slide.

  The stopper 1 includes a pair of support members 14 on both sides of the regulating member 11. The support member 14 is made of an L-shaped plate member. The stopper 1 is attached to the storage portion 30a of the vehicle body 30 with a bolt member 14a or the like via the support member 14.

  The support member 14 rotatably supports the regulating member 11 via the rotary shaft 10 that is pivotally supported at the rear portion of the front-rear direction 30b. The stopper 1 includes a lever 13. The lever 13 is fixed to the rotating shaft 10. Therefore, the control member 11 can be rotated around the rotation shaft 10 by operating the lever 13.

  The stopper 1 includes a torsion coil spring 12. The torsion coil spring 12 has one end 12 a fixed to the support member 14 and the other end 12 b fixed to the regulating member 11. Since the support member 14 is fixed to the vehicle body 30, the torsion coil spring 12 biases the rotation of the regulating member 11 about the rotation shaft 10.

[Action of torsion coil spring]
FIG. 4 is a diagram for explaining the operation of the torsion coil spring. FIG. 4 is a side view showing the stopper 1. In FIG. 4, the support member 14 is represented by a two-dot chain line.

  The dead line 15 a is a line connecting the center 10 a of the rotating shaft 10 and one end 12 a of the torsion coil spring 12. The spring line 15 b is a line connecting the one end 12 a and the other end 12 b of the torsion coil spring 12.

  As described above, the rotating shaft 10 and the one end 12a of the torsion coil spring 12 are supported by the support member 14 fixed to the vehicle body 30 (FIG. 3B). The other end 12b of the torsion coil spring 12 is supported by a rotatable restricting member 11 (FIG. 3B). Accordingly, the position of the deadline 15a is always fixed, and when the regulating member 11 is rotated, the spring line 15b is rotated around the one end 12a.

  FIG. 4A shows the first position 1A in the regulating member 11. In the first position 1A, the spring line 15b is located above the dead line 15a. The torsion coil spring 12 is biased in a direction in which the one end 12a and the other end 12b are separated from each other by a spring force (biasing force). Therefore, at this position, the torsion coil spring 12 urges the restricting member 11 in the clockwise direction (arrow direction) in the drawing around the rotation shaft 10. Then, when the lever 13 hits a notch-shaped contact portion 14a provided on the support member 14, the regulating member 11 is fixed to the first position 1A.

  FIG. 4B shows the neutral position 1 </ b> C in the regulating member 11. In the neutral position 1C, the spring line 15b is located on an extension line of the dead line 15a. At this position, the torsion coil spring 12 does not rotate the regulating member 11 around the rotation shaft 10. That is, at this position, the regulating member 11 is not urged to rotate by the torsion coil spring 12 and is balanced in rotation.

  FIG. 4C shows the second position 1B in the regulating member 11. In the second position 1B, the spring line 15b is positioned below the dead line 15a. At this position, the torsion coil spring 12 urges the restricting member 11 in the counterclockwise direction (arrow direction) in the drawing around the rotation shaft 10. Then, the restricting member 11 hits the vehicle body side contact portion 34 provided on the vehicle body 30 and is fixed to the second position 1B.

[Stopper operation]
FIG. 5 is a diagram for explaining the operation of the stopper. FIGS. 5A1 to 5A3 show a state where the stopper 1 is unlocked, FIGS. 5B1 to 5B3 show a state where the battery 2 is pulled out, and FIGS. 5C1 to 5C3 show a state where the battery 2 is pulled out. Indicates the state where is pushed in.

An operation for releasing the lock of the stopper 1 will be described.
As described above, when the regulating member 11 is in the first position 1A (FIG. 5 (a1)), the regulating member 11 is fixed in position, so that the battery 2 is locked to the notch portion 11a and the battery 2 is moved in the front-rear direction 30b. The rearward sliding at is restricted.

  Then, the operator O operates the lever 13 to move the regulating member 11 from the first position 1A (FIG. 5A1) to the second position 1B (FIG. 5A3) through the neutral position 1c (FIG. 5A2). )), The notch portion 11a is fixed below the bottom surface 2a of the battery 2 and allows the battery 2 to slide in the front-rear direction 30b (unlocked).

The operation of pulling out the battery 2 will be described.
When the stopper 1 is unlocked, the regulating member 11 is in the second position 1B (FIG. 5 (b1)), and the lever 13 is positioned above the bottom surface 2a of the battery 2. In this state, the battery 2 is slid rearward in the front-rear direction 30b (drawing direction 2A), the battery 2 is applied to the lever 13 and further slid.

  By applying the battery 2 to the lever 13, the regulating member 11 changes from the second position 1B to the contact position 1D through the neutral position 1C (FIG. 5 (b2)). In the contact position 1D, the spring line 15b is located above the dead line 15a. Therefore, the torsion coil spring 12 urges the regulating member 11 in the clockwise direction (arrow direction) in the drawing around the rotation shaft 10. Then, the regulating member 11 is urged while being in contact with the bottom surface 2 a of the battery 2. In this state, the battery 2 slides above the stopper 1.

  Then, by pulling out the battery 2, the regulating member 11 is released from the contact of the bottom surface 2a of the battery 2 and is in the first position 1A by the biasing force of the torsion coil spring 12 (FIG. 5 (b3)).

The pushing operation of the battery 2 will be described.
As the battery 2 is pulled out, the regulating member 11 is in the first position 1A (FIG. 5 (c1)), and in this state, the battery 2 is slid forward (in the pushing direction 2B) in the front-rear direction 30b. The battery 2 is further slid against the regulating member 11.

  As a result, the regulating member 11 is abutted against the bottom surface 2a of the battery 2 and is urged to change from the first position 1A to the abutting position 1D (FIG. 5 (c2)).

  When the battery 2 is further pushed in, the restricting member 11 is fixed at the first position 1A (FIG. 5 (c3)), and the notch 11a restricts the backward sliding of the battery 2 in the front-rear direction 30b.

  As described above, when the battery 2 is replaced, the worker O moves the regulating member 11 from the first position 1A to the second position 1B. Since the battery 2 can be pulled out with the biasing member 12 biasing the regulating member 11 to the second position 1B, the operator can pull out the heavy battery 2 with both hands, and There is no danger of pinching. Further, in the process of sliding the battery 2 in the pull-out direction 2A, the regulating member 11 is changed from the second position 1B to the first position 1A. For this reason, it is only necessary to operate the stopper 2 once at a time, and the labor is reduced.

  In the above-described embodiment, the torsion coil spring 12 is employed as the stopper 1, but various urging members such as a compression coil spring and a leaf spring can be employed. The stopper 1 is disposed below the battery 2, but may be disposed on the side or above. The stopper 1 locks the battery 2 at the notch 11a. However, the stopper 1 may be regulated by sliding the battery 2 against the regulating member 11. Moreover, although the stopper 1 was employ | adopted for the towing vehicle 3, it can be employ | adopted also for various vehicles (forklift etc.) which mount a slide type battery.

It is a side view which shows the state which pulls out a battery from a tow vehicle. It is the perspective view which looked at the towing vehicle from back. It is a figure for demonstrating the structure of a stopper. It is a figure for demonstrating the effect | action of a torsion coil spring. It is a figure for demonstrating operation | movement of a stopper.
