Abstract

An object of the present invention is to provide a battery car that uses an eccentric wheel as a drive wheel, adds a wave motion to the operation of a conventional horizontal running, and provides shock buffering when the auxiliary wheel is worn and safety to the surroundings during unmanned running Provided.
When a battery car puts money into a coin slot 6, a switch is turned on and travels forward. When the battery car 7 is traveling forward, the front part of the battery car 7 moves while moving up and down, thereby causing a wave motion and a change in speed with respect to the traveling direction. When the handle 5 is released, the handle 5 naturally rotates in the unmanned circuit direction 9 and travels while drawing the unmanned circuit arc 8. When getting on and off or turning the handle 5 to the left or right, the impact is absorbed by the auxiliary wheel 14 provided with a buffer mechanism, and the infant can operate without being surprised by the impact. When an unmanned ride is made, the risk of collision with a person, a fixture in the facility, and the like is reduced by making a round trip on a certain circle along the unmanned round arc trajectory 8.

Description

  This invention relates to the operation of a battery car in a small stationary vehicle for play.

Conventionally, there is a battery car of a small vehicle for play. Basically, it is a tricycle consisting of a drive unit including a drive wheel and a rear wheel. A caster is provided on the left side of the front part of the body frame as an auxiliary wheel when the balance is lost.
The auxiliary wheel is in contact with the ground at the same height as the driving wheel, and is equipped with a rear wheel to become a pseudo four-wheeled vehicle, keeping the battery car parallel.

  The drive unit has a drive wheel and a drive device. The drive wheel drives the rotation of the geared motor via a transmission component, and rotates around the center of the drive wheel as the central axis, so the drive wheel rotates in a perfect circle. The battery car runs slowly in parallel.

The drive part is also attached to the center of the front part of the body frame with a lead angle of 10 degrees. The steering wheel is directly connected to the steering wheel at the upper part of the drive part, and the drive part moves left and right. Also moves left and right and steers.
The auxiliary wheel is provided on the left side of the drive wheel, and is attached directly to the frame while maintaining a height balance with the drive wheel.

  Drive slowly in parallel in the time range set in advance by inserting coins. If you get off while driving, it will continue to move with the handle released, so it will continue to move for less than the set time, and safety considerations for the surroundings during unmanned driving are fully taken Absent.

According to the above technology, the battery car of a small vehicle for play is traveling only in parallel, and the auxiliary wheel is in contact with the ground at the same height as the driving wheel. The height of the vehicle becomes unbalanced, and the auxiliary wheel hits the floor when getting on and off and steering, and an impact is generated.
For safety reasons, the running speed is slow, so you may get off during the boarding, and will continue to run unattended for less than the set time, causing collisions with people and fixtures in the facility, etc. The safety to the surroundings is not sufficiently maintained.
Therefore, this device uses an eccentric wheel as the driving wheel, adds a wave motion to the operation of the conventional horizontal running, and a battery that can keep shock when the auxiliary wheel is worn and safety to the surroundings during unmanned running Car is an issue.

  In the first device, the drive wheel is supported by a drive wheel center support shaft provided in the drive unit 11, and a drive wheel sprocket 22 is connected to one end of the drive wheel center support shaft.

The rotation of the geared motor 13 is transmitted from the motor part sprocket 24 to the drive wheel sprocket 22 via the transmission component 23, and the eccentric drive wheel 3 is driven to rotate in an ellipse, so that the vehicle body frame 12 changes the wavy motion direction 4 The battery car 7 runs slowly while drawing.
Therefore, the vehicle travels while undulating by repeating the movement shown in FIG.

  In the second device, a caster 18 as an auxiliary wheel 14 is mounted on a caster mounting base 25, and the caster mounting base 25 and the caster mounting shaft 17 are connected.

  By using the caster mounting shaft 17 as a spring support shaft and mounting the spring 19 between the spring housing 20 and the flange 27, the caster mounting shaft 17 supports the spring 19 and is joined to the vehicle body frame 12. A damper is formed between the spring 27 and the flange 27 to provide a buffering effect, and the spring housing 20 protects the swaying portion of the spring 19.

  In the third device, the fixed position of the drive unit 11 is separated from the center of the front part of the vehicle body frame 12 to the right, and the lead angle 16 is 10 degrees, and the drive unit 11 moves to the left according to the natural law associated with the first device. The battery car 7 continues to make a round turn in the unmanned round direction 9 with a radius corresponding to the length of the wheel base.

  By using the eccentric wheel 3 in which the conventional drive wheel shaft center 1 is eccentric by the first device, the wavy motion 4 and the speed change in the front-rear direction are added, and a new movement is added. Amusement can be increased, and at the same time appeal and customer attraction can be improved.

  By the second device, the shock generated when the auxiliary wheel 14 is worn can be buffered, and at the same time, the shock when the load is applied to the auxiliary wheel 14 is reduced, so that the infant is surprised. You can get on and ride without worrying, and you can get on and off without any shock.

  In the third device, the effect of the first device and the lead angle 16 with the vehicle body frame 12 to which the drive unit 11 is joined are 10 degrees, and the battery car 7 is unmanned with respect to the traveling direction when the handle 5 is released. Since it is now possible to make a left turn in the rounding direction 9, it travels along the unmanned rounding arc trajectory 8 during unmanned travel, minimizing collisions with obstacles and improving safety.

(B) The battery car of the small vehicle for play of the present invention turns on when the money is inserted into the coin slot 6, and travels forward.
(B) As shown in FIG. 5, when the vehicle car 7 is traveling forward, the front part of the battery car 7 moves while moving up and down, thereby causing a wave motion and a change in speed with respect to the traveling direction.
(C) Hold the steering wheel 5 and steer it. When the handle 5 is released, the handle 5 naturally rotates in the unmanned circuit direction 9 and travels while drawing the unmanned circuit arc 8.
(D) When getting on and off or turning the handle 5 to the left or right, the impact is absorbed by the auxiliary wheel 14 provided with a buffer mechanism, and the infant can operate without being surprised by the impact.
Therefore, it has become possible to entertain children with movements that are different from conventional battery cars, and to ride infants with peace of mind.
When unmanned boarding, it is possible to reduce the risk of collisions with people and fixtures in the facility by traveling around a certain circle along the unmanned circular arc trajectory 8, thus improving safety.

"Other embodiments"
(B) In the embodiment of FIG. 1, the axis of the drive wheel is eccentric from the center of the drive wheel, but in other embodiments, the eccentric distance from the center of the drive wheel is changed according to the movement. Also good.
(B) Although the exterior of FIG. 3 is a police car, it may be changed to an exterior suitable for the application.
(C) Not only forward travel but also reverse travel may be possible.
