Description

Automatic swing device

Technical field

The invention relates to the field of rocking toys, and in particular to an automatic rocking device applied to a rocking toy or a decorative device.

Background technique

With the development of technology, people's living standards are gradually improved. According to personal taste or corporate image needs, they are usually placed on the desk of the office space of the office, or on the desk of the home study study room. In general, there are special fixed placements or toys. In order to attract the eye and improve the taste, it is usually preferred to choose an automatic swing toy that will be self-acting and similar to the tumbler.

At present, the above-mentioned tumbler-type automatic swinging toy on the market is generally provided with a fixed seat, which is rocked by a movable member provided on the fixed seat. For example, the shape is made into a display similar to a simulated flowerpot. The fixed seat is a flower pot, and the swinging piece on the fixed seat is a flower body. Such a swinging toy has a small visual change in the overall swing, and is not easy to attract the eye. Therefore, some manufacturers create a curved surface on the bottom surface of the fixed seat, and swing the movable member on the fixed seat to drive the fixed seat to swing together by external force. Such a swing toy has an increased amplitude of the overall swing, and requires a certain volume of the movable member. In order to establish enough external force to drive the fixed seat to swing.

At present, this type of swinging toy has been gradually reduced, which will reflect the sensation and be liked by people. Therefore, the way of swinging the fixed seat by a certain volume of moving parts has gradually failed to meet the demand for small production.

On the other hand, the manner in which the fixed seat swings by the force of the movable member is that the bottom surface of the fixed seat is a curved surface, and cannot be stably contacted with the tabletop. During the swinging process, the external force drives the swing, and the swinging toy is easily displaced as a whole. Long swings can cause the rocking toy to move, falling off the table, causing damage or other dangerous conditions.

Summary of the invention

The object of the present invention is to provide a novel automatic rocking device applied to a rocking toy or a decorative device, which has a simple structure and a small volume, and realizes swinging by changing the center of gravity of the rocking body itself to generate a force from the inside, so that the automatic rocking device is applied. The furnishings and toys do not easily shift during the continuous sway, causing damage or other dangerous conditions.

In order to achieve the above object, the technical solution of the present invention is:

An automatic rocking device includes a rocking body and a curved rocking structure, the arc rocking structure is disposed at a bottom of the rocking body for supporting a reciprocating swing of the rocking body; the rocking body includes a movable weight member and a driving structure, The movable weight member is driven by the driving structure to change the position of the center of gravity of the swinging body, and the force is used to drive the swinging body to perform an inertial rocking motion along the curved rocking structure.

As a first modification of the automatic rocking device of the present invention, the rocking body further includes a rack, the movable weight member and the driving structure are an electric motor, and the motor is provided with a gear that cooperates with the rack and passes through The gear is driven to mesh with the rack, and the motor is moved along the rack so that the weight of the swing body changes with the movement of the motor, thereby making a reciprocating rocking motion.

Further, the rack is a linear or curved rack. The arc-shaped rack can cooperate with the arc-shaped rocking structure at the bottom of the rocking body. When the motor is meshed with the rack by the gear and moves along the trajectory of the arc-shaped rack, the swing amplitude can be effectively increased, and Guarantee the stability of the swing and improve the swing effect.

Further, the direction in which the rack is disposed coincides with the arc-shaped rocking structure, so that the rocking body performs a reciprocating rocking motion in a direction in which the arc-shaped rocking structure is disposed.

As a second modification of the automatic rocking device of the present invention, the rocking body further includes a horizontally disposed annular rack, the movable weight member and the driving structure are an electric motor, and the motor is provided with the annular rack Cooperating gears, and by driving the gears to mesh with the annular rack, the motor is caused to rotate horizontally along the annular rack. Passing the motor through the driving gear, centering on the annular rack, horizontally rotating around the ring gear, so that the center of gravity of the rocking body changes with the rotation of the motor, and reciprocating rocking motion, further saving space, effectively Reduce the volume of the swinging body.

In the above two solutions, since the movable weight member and the driving structure are the same as the motor body, the motor itself is the driving mechanism for generating power, and the movable weight member itself, fully utilizing the gravity characteristic of the motor body, effectively Reducing the number of internal parts and their footprint makes the internal connection structure simpler and smaller.

As a third modification of the automatic rocking device of the present invention, the movable weight member is an eccentric wheel, and the driving structure is an electric motor, and the eccentric wheel is coupled to the motor shaft.

On the basis of the above, the motor is horizontally disposed, and the eccentric wheel is vertically oscillated and reciprocated under the driving of the motor. Through the sway of the eccentric wheel, thereby changing the position of the center of gravity of the swinging body, an internal force is generated to drive the swinging body to reciprocate along the arcuate rocking structure.

As a further improvement of the above-mentioned movable weight member and driving structure, the motor is vertically disposed, and the eccentric wheel is horizontally rotated by the driving of the motor. Since the arc-shaped rocking structure supports the rocking body at the bottom, when the eccentric wheel rotates horizontally, the center of gravity of the rocking body also changes to make a reciprocating rocking motion.

As a further improvement of the automatic rocking device of the present invention, the curved rocking structure is integrally or detachably connected to the rocking body. The detachable connection structure allows the rocking device to be paired with different curved rocking structures to produce a variety of rocking action effects.

Further, the arc-shaped rocking structure is a curved surface or an arc-shaped bracket to be replaced with different toys, such as a truncate toy adopting a curved surface structure, and a sled toy adopting a curved bracket structure.

The automatic rocking device of the present invention has the beneficial effects that, under the driving structure, the movable weight member reciprocates in the rocking body, changes the center of gravity of the rocking body, and generates an internal force to make the curved bottom portion The swinging body loses balance and achieves reciprocating rocking. The movable weight member generates a rocking driving force inside the rocking body, and does not need to pass through an external driving structure, so that the overall structure of the device is simpler and the volume is smaller. On the other hand, by changing the center of gravity of the swinging body itself, the swing is generated from the inside to cause the swing or the toy to be applied, and the swing or the toy of the automatic swinging device is not easily displaced during the continuous rocking, causing damage or other dangers. The situation has occurred.
