Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a toy drive unit that uses a trap to drive the drive parts of various toys.

2. Description of the Related Art In recent years, various parts of various toys have been configured to be movable, allowing various movements to be performed, thereby allowing a variety of play experiences to be enjoyed. In this case, the drive device for performing the various movements is required to be small and resistant to shocks and the like. In particular, toys for relatively young children that are operated and played within a certain area, such as on a tabletop, may collide with the surrounding fence or fall from the tabletop onto the floor. This often occurs, and there is an urgent need to make the drive system more robust.

The present invention has been made in view of the above-mentioned circumstances, and is one in which a motor, a battery, and a power transmission means constituting a drive device are integrated into a unit.The case of the unit is divided, and the motor and battery are housed inside the unit. By forming a storage area for the power transmission means and a housing for the power transmission means, and using these storage areas as a cushioning material, the motor, battery, and power transmission means are integrally built into the case, making the toy compact and resistant to impact. The purpose is to provide a drive unit for

An embodiment of the present invention shown in the drawings will be described below.

FIG. 1 is an exploded perspective view of the toy drive unit of the embodiment.
FIG. 2 is an assembled perspective view of FIG. 1. In these drawings, 10 is a drive unit case, 20 is a motor, and 30 is a drive unit case.
is a battery, and 40 is a power transmission means.

The case 10 is divided into three parts: left and right cases 10a and 10b, and a central case IOC.

A protrusion 11 is provided on the central case 10c side of 10b, and fitting holes 12 into which the protrusion 11 fits are provided on both sides of the central case IOC, so that assembly is possible.

Also, inside the case 10, a motor 20 and a battery 3 are provided.
A motor accommodating part 13, a battery accommodating part 14, and a power transmitting means accommodating part 15 each having a shape corresponding to the shape of the motor 0 and the power transmitting means 40 are formed. Left and right cases 10a of case 10
,, 10b and the central case IOC are each molded from a synthetic resin material, etc., and each of the above-mentioned storage sections],
3, 14, and 15 securely house and hold the motor 20, battery 30, and power transmission means 4o using elasticity of synthetic resin or the like. The central case 10c has a structure in which the partition wall between the motor storage section 13 and the battery storage section 14 and the upper surface of the battery storage section 14 are formed into an open spring body shape to increase the holding force. Left and right case 10a
The power transmission means housing portion 15 of 10b is provided with a lead-out hole 16 for an output shaft 43, which will be described later.
Terminal 2 of the motor 10, which will be described later, is located in the motor storage portion 13 of b.
Two protruding windows 17 are formed. Reference numeral 18a denotes a protrusion provided at the front lower end of the left and right cases 10a and 10b, which fits into a fitting hole 51a of a chassis 51, which will be described later, to secure the case 10.
The front part of the chassis 51 is fixed to the chassis 51. 18b is case 10
A groove provided at the rear of the entire body engages with a locking portion 52a of a fixing member 52, which will be described later. Auxiliary wheels 19a are attached to both ends of the axle 19b, and are rotatably attached to the axle support portion 19C via the axle 19b.

The motor 20 has a rectangular parallelepiped outer shape, and is mainly stored and held in the storage section 13 of the central case 10c.

A motor shaft 21 protrudes from the left side of the motor 20.
A terminal 22 protrudes from the right side. This terminal 22 is connected to a power supply lead wire 23 and a capacitor 24 by soldering, and its tip is exposed to the outside of the case IO through the window 17 of the right case part 10b, so that the terminal 22 can be cooled by air. be. The battery 30 is formed in a cylindrical shape and is stored and held in the battery storage part 14 in a state adjacent to the motor 20.

The power transmission means 40 is fixed to a small gear 41 fitted to the tip of the motor shaft 21, a gear 42 meshing with the small gear 41, and the gear 42, and has both ends connected to the left and right cases 10a, 10.
and an output shaft 43 protruding outside from the outlet hole 16 of b. The power transmission means storage section 15 has a gear 41
．． 42 and a part that rotatably supports the output shaft 43. Furthermore, tires 45 are attached to both ends of the output shaft 43 that protrudes outside the case 10 via wheels 44 . Note that in this embodiment, the output shaft 4
However, depending on the type of toy, only one end of the output shaft 43 may be projected outside the case 10.
It may be made to protrude outside.

When assembling a drive unit having such a configuration, the motor 20, battery 30, and power transmission means 40 are housed and held in the respective housing sections 13, 14, and 15 of the central case IOC, and then the output shaft 43 The protrusions 11 of the left and right cases 10a, 10b are arranged so that
are fitted into the fitting holes 12 of the central case IOC, and the left and right cases 10a, 10b and the central case 10c are integrally assembled. From this K, the drive unit integrally houses the motor 20, the battery 30, and the power transmission means 40 in the case 10, with each storage section 13, 14, 15 used as a cushioning material.

FIGS. 3 and 4 show an internal side view and an overall perspective view of an example in which the toy drive unit of this embodiment is used in a traveling toy. In this example, the toy drive unit is a traveling toy 50.
It is used as a traveling device to drive the rear wheel 45, and the front part is fitted with a protrusion 18a and a fitting hole 51a, and the rear part is fitted with a groove 1.
By fixing the fixing member 52 to the chassis 51 with the screw 53, it is firmly fixed to the chassis 51.

FIG. 5 shows an internal view of an example in which the toy drive unit of this embodiment is used in a robot toy. In this example, the toy drive unit connects only one end of the output shaft 43 to the case 10.
The running wheel 63 of the robot toy 6o is rotated through the deceleration mechanisms 61 and 62, and
It is used as a device for operating the arm portion 64.

Furthermore, the toy drive unit of the present invention can be used in various toys having a drive unit, such as moving toys or robot toys, as well as animal toys and doll toys. Also, motor 2
0 and the shape of the battery 30, the gear mechanism of the power transmission means 40, etc. are not limited to those of the above embodiments, and for example, a pulley or the like may be used for the power transmission means 40. Of course, the shape of each of the storage sections 13, 14, and 15 can also be made to correspond to the shape of the motor 20 and the like.

As described above, according to the present invention, the case is formed into a split type, and the housing portions for the motor, battery, and power transmission means are formed inside the case, and the motor, battery, and power transmission means are housed and held in these housing portions. Since the drive unit is built integrally within the case, the drive unit can be made smaller and can be used as a drive device for various parts of toys. It also has high impact resistance and will not easily break down even if it is handled somewhat roughly by children.

Furthermore, it has various effects such as easy assembly and improved assembly work.
