Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a small-sized traveling toy that can be driven by remote control or the like and has a streamlined vehicle body.

Traveling toys are one of the most popular toys among many toys, and in particular, traveling toys that have built-in electronic circuits and motor units and can be moved in various ways by remote control etc. are popular not only for children but also for adults. It is also popular among but,
Conventional running toys of this type require a printed circuit board for an electronic circuit that receives signals from a remote control device, etc. and sends various running signals to the motor unit, and the motor unit, making it necessary to downsize the running toy. Due to the limitations of these printed circuit boards and motor units, the body shape of the traveling toy had to be box-shaped. Therefore, it is difficult to apply this type of traveling toy to a small streamlined traveling toy, and the types and types of traveling toys are limited.

The present invention has been made in view of the above-mentioned circumstances, and includes forming the mounting portion of the printed circuit board of the chassis in a forward-slanted shape, and
By forming the motor unit containing the motor, battery, etc. in an inclined shape, and by positioning the front part of the motor unit below the chassis mounting part, the printed circuit board with electronic components and the motor unit can be placed inside the streamlined vehicle body. To provide a traveling toy that can be stored compactly and can be applied to a traveling toy consisting of a small streamlined vehicle body and can be driven by remote control or the like.

It will be posted on. Next, the front engagement groove 41 of the holding member 4o is engaged with the rear end protruding piece 23 of the printed circuit board 2o,
In addition, the rear engagement piece 42 is inserted into the rear groove 3 of the motor unit 30.
7 and placed on the motor unit) 30. Thereafter, a screw 44 is screwed into the screw hole 13 of the chassis 10 from the through hole 43 of the holding member 40, and is firmly fixed.

In this way, the printed circuit board 20 can be fixed in a forward-inclined manner, and the inclined motor unit 30 can be assembled with its front part positioned below the printed circuit board 20 and stacked on top of each other. It can be built into the streamlined vehicle body.

The connector 50 has a switch 51 and a connecting portion (not shown) on its lower surface, and is housed in a casing 15 having windows on the top and bottom so that these are exposed on the bottom surface of the shear 710. This connector 50 connects a lead terminal 52 on the top surface of the printed circuit board 20 to a slave circuit, a battery 34 of the motor unit 30, etc. by a lead wire (not shown). Therefore, the battery 34 is charged by the external charging device via a connection portion (not shown).

The front wheel support body 60 has protrusions 61a and 61 on the lower and upper parts.
b, and the lower protrusion 61a is inserted into the fitting hole 16 of the chassis 10.
At the same time, the upper protrusion 61b is fitted into the fitting hole 72 of the fixing member 70 and fixed. In this case, one or both of the lower and upper protrusions 51a, 6
1b are provided to prevent the front wheel support body 60 from swinging. A front wheel 62 is rotatably attached to the front wheel support 60 by a pin 63.

The fixing member 70 has an opening 71 in the center for holding the connector 50, and front wheel supports 6 on both sides of the opening 710.
A fitting hole 72 into which the upper projection 61b of No. 0 fits is provided. 73 is a through hole for a screw 74 provided in the front part of the opening 71, and is provided corresponding to the screw hole 17 of the chassis 10.

When the connector 50 and the front wheel support 60 are fixed to the front part of the chassis 10 by the fixing member 70, the connector 50 is housed in the housing part 15, and the front wheel support 60 is
The lower protrusion 61b of the chassis 10 is fitted into the fitting hole 16 of the chassis 10. Next, the fixing member 70 is inserted into the opening 71 of the housing part 15.
At the same time, the upper fitting portion 61b of the front wheel support 60 is fitted into the fitting hole 72, thereby fixing the connector 50 and the front wheel support 60. Thereafter, the screw 74 is screwed into the screw hole 17 of the chassis 10 from the through hole 73 of the fixing member 70 to firmly fix the fixing member 70 to the chassis 10.

In this way, the printed circuit board 20 and the motor unit) 3
0 to the chassis 10 with the holding member 40, and the connector 5
0 and the front wheel support 60 are fixed to the chassis 10 with the fixing member 70 (see FIG. 2), and then a streamlined vehicle body 80 is attached to form a complete running toy (see FIG. 1).

The present invention incorporates the printed circuit board 20, motor unit 30, etc. that make up the traveling toy in a streamlined vehicle body 80, and constructs a chassis so that the rear wheels 35 are located at the center of gravity of the entire traveling toy when assembled as described above. The inclination angle of the printed circuit board mounting portion 11 of 10, the inclination angle and fixed position of the motor unit 30, the mounting position of the rear wheel 35, the arrangement state of the motor 33 and battery 34 in the motor unit 30, etc. are selected. Therefore, if you want to start and accelerate quietly, you will be driving normally, but if you start suddenly.

When accelerating, the running toy falls backwards and performs a wheelie using the rear wheels 35 and auxiliary wheels 38.

Conversely, if you suddenly stop or decelerate while doing a wheelie, the toy will fall forward and assume its normal running position, allowing you to enjoy various running forms and their changes. .

The second embodiment shown in FIG. 5 is a motor unit) 30
The case 31 is tilted in an inverted 〈 shape, and the output shaft 32 of the rear wheel 35, the motor 33, and the battery 3 are installed inside the case 31.
4 is arranged in an inverted 〈 shape. According to this embodiment, the rear part of the traveling toy can be shortened. In this embodiment as well, the fixing means such as the motor unit 30 and the possibility of wheelie running are exactly the same as those in the first embodiment.

Note that the inclination angle of the mounting portion 11 of the printed circuit board 20, the motor 33 in the motor unit 30, etc. The arrangement of the battery 34, etc. can be changed as appropriate.

As described above, according to the present invention, the printed circuit board mounting portion of the chassis is formed in a forward-inclined shape, the printed circuit board is fixed in the forward-inclined state, and the motor unit formed in an inclined shape is
Since the front part is positioned below the printed circuit board and fixed in an overlapping state, the constituent members of the traveling toy can be arranged in a chevron shape. Therefore, the vehicle body can be made streamlined, making it possible to imitate the shape of the vehicle body of various vehicles or vehicle types, thereby providing even more enjoyment to the player. Also, the arrangement of each component.

It can also be fixed very compactly and can be applied to small traveling toys.
