Description

a wheel shaker

technical field

The invention relates to a rocker, in particular to a wheeled rocker which can drive rocking chairs, swings and the like to swing.

Background technique

Traditional electric rocking chairs, electric swings and other rocking devices include a base, a rocking body mounted on the base and a rocker that drives the rocking body to swing. The two ends of the rocker are respectively fixed on the base and the rocking body. The rockers used in traditional electric rocking chairs, electric swings and other rocking devices are all designed for the specific rocking device. The rockers on different rocking devices have different structures and cannot be used interchangeably. Therefore, the rockers on different rocking devices Different molds need to be set up for manufacturing, which not only increases the production difficulty of various swing devices, but also increases the production cost of the swing device, and at the same time increases the difficulty of assembling the swing device.

Contents of the invention

In order to overcome the deficiencies of the prior art, the present invention provides a wheeled rocker that can be applied to different rocking devices such as electric rocking chairs, electric swings and other rocking devices.

The technical solution adopted by the present invention to solve its technical problems is:

A wheeled rocker, including a swing arm and a driving mechanism, is characterized in that one end of the swing arm is equipped with a rotating shaft, one end of the rotating shaft is equipped with a fixing mechanism that can be fixed on the swing device, and the other end of the swing arm is equipped with a roller. The driving mechanism is installed in the roller, and the output end of the driving mechanism is fixedly connected with the swing arm.

Wherein, the driving mechanism includes a motor and a reducer connected to the motor, the motor is connected with speed, direction and position sensors, and the swing arm is fixedly connected to the output shaft of the reducer.

As a preferred embodiment of the present invention, the fixing mechanism includes a body with an opening, a splint is arranged in the opening of the body, a screw is fixed on the splint, the screw is threadedly connected with the body, and the body is provided with a connection block.

As an improvement of the above embodiment of the present invention, the connecting block is hinged on the body through a pin shaft, a connecting rod is provided on the connecting block, and a hole for accommodating the connecting rod is provided on the rotating shaft.

The beneficial effects of the present invention are: the present invention can be applied to different rocking devices, such as electric rocking chairs, electric swings, etc., thus avoiding the process of separately mold-making and producing the rockers of different rocking devices, thereby reducing the production of rocking devices. Difficulty can also reduce the production cost of the swinging device. During assembly, only the rollers of the swinging device need to be placed on the ground, and the other end is fixed on the swinging device through a fixing device, thus bringing great convenience to the assembly of the swinging device.

Description of drawings

The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

Fig. 1 is a three-dimensional exploded schematic diagram of the present invention;

Fig. 2 is a perspective view of the present invention;

Fig. 3 is a three-dimensional schematic diagram of a fixing device;

FIG. 4 is an exploded perspective view of FIG. 3 .

Detailed ways

With reference to Fig. 1, Fig. 2, a kind of wheel type rocker disclosed by the present invention comprises a swing arm 1 and a drive mechanism, wherein one end of the swing arm 1 is equipped with a rotating shaft 2, and one end of the rotating shaft 2 is equipped with a shaft that can be fixed on the swing device. As for the fixing mechanism, a roller 3 is installed on the other end of the swing arm 1 , the driving mechanism is installed in the roller 3 , and the output end of the driving mechanism is fixedly connected with the swing arm 1 . When in use, the roller of the wheeled swinger is placed on the ground, and the other end is fixed on the swinging device through a fixing device. The driving mechanism drives the swing arm to swing. When the swing arm swings, it drives the other end of the swing arm to move up and down, and the swing arm rotates around the shaft. Make the swinging device swing while the rollers roll on the ground to adapt to the change of the lateral displacement of the swing arm during swinging.

As shown in the figure, the drive mechanism that the present invention adopts comprises motor 4 and the speed reducer 5 that is connected with motor 4, is connected with speed, direction and position sensor on motor, and speed, direction and position sensor can be controlled by mouse pair tube and grating 6 Composition, the swing arm 1 is fixedly connected with the output shaft 7 of the reducer 5 . The invention perceives the rotation angle of the swing arm through speed, direction and position sensors, and feeds back to the control system of the drive mechanism, so that the control system controls the motor to rotate forward and reverse within a certain angle, so that the swing arm swings within a certain angle.

The rocker of the present invention can be commonly used in different rocking devices, such as electric rocking chairs, electric swings, etc., thereby eliminating the need for different rocking devices. To reduce the production cost of the swinging device, only the rollers of the swinging device need to be placed on the ground during assembly, and the other end is fixed on the swinging device through a fixing device, thus bringing great convenience to the assembly of the swinging device.

Referring to FIG. 3 , FIG. 3 is a structural schematic diagram of a fixing mechanism adopted in the present invention. As shown in the figure, the fixing mechanism includes a body 8 with an opening. A splint 9 is arranged in the opening of the body 8. A screw 10 is fixed on the splint 9. The screw 10 is screwed to the body 8. The body 8 is provided with a shaft that can be installed on the shaft. 2 on the connection block 11.

Referring to Figure 4, in order to facilitate the installation of the fixing device on different fixtures, the connecting block 11 adopts a structure that is hinged on the body 8 through the pin shaft 12. The opening can be matched with the fixture. And the connecting block 11 is provided with a connecting rod 13, and one side of the rotating shaft 2 is provided with a hole (not shown) for accommodating the connecting rod. When the fixing device is assembled with the swing arm, it is only necessary to insert the connecting rod into the hole on the rotating shaft within.

The above description is only a preferred embodiment of the present invention, and the protection scope of the present invention cannot be limited by it. As long as the equivalent changes and modifications are made according to the protection scope of the present invention, they should still fall within the scope of the present invention.
