Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a switch structure that performs electrical switching.

[Prior Art and Problems to be Solved] Conventionally, toys and the like that operate by obtaining power from batteries or the like are equipped with a switch for starting and stopping or for changing the operating state.

However, these conventional switches, such as toggle switches and slide switches, generally have a structure that includes an operating piece that switches the contacts, and the switch operation is performed by directly operating the operating piece. The drawback was that it required manual effort to switch over.

[Means for Solving Problems] The present invention, which solves the above-mentioned conventional problems, has a switch structure that performs electrical switching, in which two switch elements that perform a switching operation by the action of magnetic force are arranged side by side in a substantially V-shape. It has a long plate shape, has one end rotatably supported so as to reciprocate over the switch element, is biased toward either side of the two switch elements, and has a weight at the other end. and a drive member having a magnetic body that operates the switch element at a position corresponding to the switch element, the drive member having a long plate shape and having a middle portion thereof freely rotatable near the rotation axis of the drive member. The holding member is pivotally supported by the switch element, and has one end abutting against the rotating shaft side end of the driving member to hold the driving member at a position separated from the switch element.

[Example] Hereinafter, an example of the present invention will be described in detail based on the drawings. In the following, a case will be explained in which the switch structure of the present invention is applied to a traveling toy.

1 to 5, the running toy of this embodiment has a drive motor 2, a transmission gear section 3, a battery 4, and a switch section 5 mounted on a chassis 1, and a car shape is mounted on the chassis 1. It is covered with a model body 20.

The drive motor 2 and the transmission gear section 3 are provided at the rear of the chassis 1, as shown in FIGS. 1 and 3, and the rotation shaft of the drive motor 2 is connected to the transmission gear section 3. The transmission gear portion 3 also includes rear wheels 6, 6 at both ends.
A shaft 7 fitted with the
is transmitted to rotate the rear wheels 6, 6. Furthermore, front wheels 8, 8 are rotatably provided at the front of the chassis 1.

Two batteries 4 are housed side by side in a battery storage section 9 formed on the chassis 1 as shown in the figure, and are connected to the drive motor 2 via a switch section 5.

The switch section 5 includes reed switches 11a, 11b, a drive member 12, and a lock lever 1 on a substrate 10.
6 is disposed above the drive motor 2 and the transmission gear section 3, as shown in FIG. The reed switches 11a and 11b are elements that each perform a switching operation by the action of an external magnetic force, and are arranged in a V-shape on the substrate 10 at predetermined intervals as shown in FIGS. 4a and 4b. The reed switches 11a, 11b are electrically wired to the drive motor 2 and batteries 4, 4 described above according to the circuit configuration shown in FIG.

Now, let's talk about the circuit configuration shown in Figure 5.
Electrical batteries 4, 4 are connected in parallel to the drive motor 2, respectively, and reed switches 11a, 11b are connected in series to the batteries 4, 4, respectively. With such a configuration, the reed switch 11
When the reed switch 11b is closed, the battery 4 connected to it and the drive motor 2 are electrically connected, and the drive motor 2 rotates in the forward direction.On the other hand, when the reed switch 11b is closed, the other battery 4 and the drive motor 2 are electrically connected, and the drive motor 2 is driven. The motor 2 is configured to rotate in a backward direction. That is, reed switch 11
By switching between a and 11b, the polarity of the battery 4 connected to the drive motor 2 changes, allowing the toy to travel forward and backward.

The drive member 12 is made of a plate-like member, and one end of the drive member 12 is rotatably supported on the center line between the reed switches 11a and 11b on the board 10 by a shaft 12a. The driving member 12 can be rotated only within the range of the opening angle between the reed switches 11a and 11b, and as shown in FIG. 11b. Note that the drive member 12
is supported at a certain height above the substrate 10 so that it can rotate without colliding with the reed switches 11a and 11b.

In addition, the reed switch 11a of the drive member 12,
A magnet 13 is provided at a position corresponding to 11b for applying a magnetic force to the reed switches 11a and 11b to perform a switching operation.
Due to the magnet 13, when the driving member 12 overlaps one of the reed switches 11a and 11b, the reed switches 11a and 11b on the overlapping side are electrically connected.

Further, a protrusion 14a provided on the free end side of the drive member 12 and a reed switch 11 on the substrate 10 are connected to each other.
A protrusion 14b provided on the center line between a and 11b
A spring 14 is installed between them. This spring 14 is for urging the drive member 12 toward either the reed switch 11a or 11b side to rotate it, and the state in which the shaft 12a and the protrusions 14a, 14b are aligned in a straight line as shown in the figure is what is called This is a point of consideration, and reed switch 11
It is designed so that it can be rotated to either side of a or 11b by biasing. A weight 15 is attached to the free end of the drive member 12 to ensure that the drive member 12 rotates.

The lock lever 16 is connected to the driving member 1 on the substrate 10.
It is rotatably supported by a shaft 17 on the shaft 12a side of No. 2. This lock lever 16 is connected to the operating section 1.
6a and a lock portion 16b, the operating portion 16
Rotate around the shaft 17 by operating a to lock the lock part 16.
When b is brought into contact with the end of the drive member 12, the drive member 12 is held at the position of the consideration point shown in FIG. 4a. Further, if the lock portion 16b is released from the end of the drive member 12 by rotating to the opposite side, the lock of the drive member 12 is released and the drive member 12 is attached to the spring 1.
4 toward the reed switch 11a or 11b. The operating portion 16a of the lock lever 16 is positioned so as to protrude outward from the rear of the body 20, so that it can be operated from the outside.

Next, the operation of the above embodiment will be explained.
First, from the state shown in Fig. 4a, the lock lever 1
6 is rotated to separate the lock portion 16a from the end of the drive member 12, thereby leaving the drive member 12 in a free state. In this state, the drive member 12 is biased by the spring 14 to switch the reed switch 11a.
11b, so for example, if you want the traveling toy to travel forward, apply an impact by hitting the rear of the body 20 to rotate the drive member 12 toward the reed switch 11a. let Furthermore, when the vehicle is to travel backwards, the driving member 12 may be positioned on the reed switch 11b side by tapping the front portion of the body 20 or the like.

Now, when the drive member 12 rotates toward the reed switch 11a, the reed switch 11a is turned on by the magnetic force of the magnet 13, the battery 4 on the reed switch 11a side and the drive motor 2 are electrically connected, and the drive motor 2 is moved in the forward direction. Rotate to. The rotation of the drive motor 2 is transmitted to the rear wheels 6 via the transmission gear section 3, and the traveling toy travels forward.

Next, when the front part of the traveling toy collides with an obstacle such as a wall while traveling forward, the drive member 12 is rotated toward the reed switch 11b by inertia force against the bias of the spring 14. As a result, reed switch 11a is turned off, and reed switch 11b is turned on instead. When the other battery 4 that drives and rotates the drive motor 2 in the reverse direction is electrically connected to the drive motor 2, the collision state is automatically switched to reverse travel. Similarly, if the rear part of the traveling toy collides with an obstacle while traveling backwards, the drive member 12 is activated by the reed switch 1.
It rotates to the 1a side and runs forward again. By the above-described operation, the switch section 5 of the running toy is switched every time there is a collision, and the running toy repeats forward running and backward running, thereby providing an interesting running state.

Note that the above embodiment shows a case where the switch structure of the present invention is applied to a running toy so that the switch is automatically switched depending on the impact received while running, but the present invention is limited to the above running toy. It can be used for toys that perform actions other than running. For example, if the switch structure of the present invention is used in a toy that changes posture, the drive member 12
The switch may be changed by rotating the switch. Furthermore, the switch structure of the present invention can also be applied to electrical appliances other than toys.

In the above embodiment, the reed switches 11a, 11
Although the case where two reed switches b are provided and switching is performed by the drive member 12 has been shown, for example, only one reed switch may be provided to simply turn on and off. Further, although a case has been shown in which the drive member 12 is rotated to move the magnet 13 toward and away from the reed switches 11a and 11b, a structure in which the drive member 12 is slid can also be adopted.

Further, although the structure is such that the lock lever 16 is brought into contact with the end of the drive member 12 to hold the drive member 12, it is sufficient that the lock lever 16 is capable of holding the drive member 12. A structure using pieces or pins or the like can be considered. Further, although the embodiment uses a reed switch that is turned on by the action of a magnetic force, it is also possible to use a switch element that is turned off when a magnetic force is applied. Also, a spring 1 that biases the drive member 12
4 is not necessarily necessary, and the drive member 12 may be moved only by its own weight.

[Effects of the invention] As described above, the present invention includes a switch element that performs a switching operation by the action of magnetic force, a drive member that has a magnetic body that operates the switch element and can approach and move away from the switch element, and the drive member. By providing a holding member that holds the member at a position away from the switch element, when the holding member is released and the driving member is freed, the posture of the target to which the switch is attached can be changed or a light impact can be applied to the target. This provides the effect of being able to switch the switch without directly operating the operating section.
