Description

Technical Field

[0001] This utility model relates to the field of transmission mechanisms, and in particular to a transmission mechanism for a rotating seat. Background Technology

[0002] A chair is a device used for people to sit on, widely used in homes, offices, transportation, leisure and entertainment venues, and many other places. Based on its purpose and structure, chairs can be divided into several types, including home chairs, office chairs, transportation chairs, and special-purpose chairs. A swivel chair is a special type of chair that can rotate around a vertical axis. Compared to ordinary chairs, swivel chairs allow users to easily adjust their orientation and change their field of vision without moving the chair itself.

[0003] In the process of developing this application, the inventors discovered the following problems with the existing technology: Currently, most swivel chairs are mainly operated manually. First, the swivel locking device must be manually released, then the chair must be manually rotated, and finally the swivel device must be locked again. The locking device is generally controlled by the foot. This type of swivel chair is cumbersome to operate, increasing the complexity of operation for the operator. However, in certain scenarios, such as amusement parks and other entertainment venues, recreational chairs need to be automatically rotated and adjusted to enhance the user experience.

[0004] Therefore, those skilled in the art have provided a transmission mechanism for a rotating seat to solve the problems mentioned in the background art. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a transmission mechanism for a rotating seat that enables the seat to rotate 180° left and right. The mechanism is simple in structure and convenient and quick to use.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] A transmission mechanism for a rotating seat includes a housing and a transmission component installed inside the housing. A base is fixedly disposed on the bottom surface inside the housing, and the transmission component is mounted on the base. The transmission component includes a transverse fixing frame fixed to the base. A main column is rotatably disposed on one side of the transverse fixing frame via a bearing, and a motor is fixedly disposed on the other side of the transverse fixing frame. A power gear is fixedly disposed at the output end of the motor. A main drive wheel meshing with the power gear is fixedly disposed on the upper end of the main column. A top seat is fixedly disposed on the upper end of the main column and is rotatably disposed on the upper end of the housing. Positioning contacts are fixedly disposed at the midpoints of both sides of the upper end face of the main drive wheel.

[0008] Furthermore, a power supply is fixedly installed on one side of the upper surface of the base.

[0009] Furthermore, a PLC control board is fixedly installed on the upper surface of the base near the rear end.

[0010] Furthermore, a sensor is fixedly installed at the midpoint of one side of the inner wall of the outer shell. The sensor is an infrared positioning sensor that performs positioning sensing and detection on the positioning contact.

[0011] Furthermore, the two positioning contacts are symmetrically swapped along the axis of the main column after each 180° rotation.

[0012] Furthermore, the diameter of the main drive wheel is four times that of the drive gear.

[0013] This utility model has the following beneficial effects:

[0014] This utility model proposes a transmission mechanism for a rotating seat. The transmission mechanism is installed and fixed to the connecting shaft seat of the seat through the upper top seat. The rotation of the top seat is achieved by the internal transmission component. The internal transmission component is equipped with positioning contacts. There are two positioning contacts, and the motor is automatically triggered after rotating 180°, thereby realizing the 180° left and right rotation drive function. Attached Figure Description

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Reference Figures 1-3This utility model provides an embodiment of a rotating seat transmission mechanism, including a housing 2 and a transmission component 3 installed inside the housing 2. A base 6 is fixedly installed on the bottom surface inside the housing 2. The transmission component 3 is installed on the base 6. The transmission component 3 includes a transverse fixing frame 306, which is fixed on the base 6. A main column 301 is rotatably installed on one side of the transverse fixing frame 306 via a bearing. A motor 305 is fixedly installed on the other side of the transverse fixing frame 306. A power gear 304 is fixedly installed at the output end of the motor 305. A main transmission wheel 303 that meshes with the power gear 304 is fixedly installed at the upper end of the main column 301. A top seat 1 is fixedly installed at the upper end of the main column 301 and is rotatably installed on the upper end of the housing 2. Positioning contacts 302 are fixedly installed at the midpoints of both sides of the upper surface of the main transmission wheel 303.

[0022] Specifically, the horizontal fixing bracket 306 provides auxiliary support and fixation for the motor 305, preventing the motor 305 from swaying and becoming unstable when suspended in the air. The gear meshing transmission method has the advantages of simple structure and stable transmission. The electric drive method of the motor 305 enables it to have intelligent control operation.

[0023] Reference Figures 2-3 A power supply 4 is fixedly installed on one side of the upper surface of the base 6. A PLC control board 7 is fixedly installed near the rear end of the upper surface of the base 6. A sensor 5 is fixedly installed at the midpoint of one side of the inner wall of the outer shell 2. The sensor 5 uses an infrared positioning sensor to perform positioning sensing detection on the positioning contact 302.

[0024] Specifically, power supply 4 provides power to motor 305, PLC control board 7 and sensor 5 to ensure the normal operation of the three electrical devices. Sensor 5 is used to detect the rotation angle of positioning contact 302 on the upper end of positioning main drive wheel 303. When positioning contact 302 rotates 180°, the automatic sensor will transmit the signal to PLC control board 7. Then PLC control board 7 controls motor 305 to perform forward and reverse rotation, thereby realizing the 180° left and right rotation operation of transmission component 3.

[0025] Reference Figure 3 The two positioning contacts 302 rotate 180° and then symmetrically switch positions along the axis of the main column 301.

[0026] Specifically, the two positioning contacts 302 are designed symmetrically with the main column 301 as the center line. The position is changed every time the positioning contact 302 rotates 180°, which ensures accurate positioning.

[0027] Reference Figure 3 The diameter of the main drive wheel 303 is four times that of the drive gear 304;

[0028] Specifically, the power gear 304, as the power output end, drives the main drive wheel 303 to rotate. The reduction in its diameter reduces the speed at which it drives the main drive wheel 303, thus preventing the seat from rotating too fast and causing discomfort during use.

[0029] Working principle: When in use, the motor 305 is started by the controller connected to the PLC control board 7. The motor 305 drives the main drive wheel 303 at the output end to rotate, which causes the power gear 304 meshing with it to rotate. Then the main column 301 rotates, which drives the top seat 1 at the upper end to rotate. The top seat 1 is fixed to the seat, realizing the rotation operation of the seat.

[0030] Secondly, two positioning contacts 302 are provided on the upper end of the main drive wheel 303. When the positioning contacts 302 rotate 180°, the internal sensor 5 automatically senses and transmits the signal to the PLC control board 7. Then, the PLC control board 7 controls the motor 305 to perform forward and reverse rotation, thereby realizing the left and right 180° rotation operation of the transmission component 3.

[0031] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
