[0032] It should be noted that the features in the embodiments of the present application can be combined with each other without conflict.

[0033] The inventors of the present application have found that considering that the backrest of an electric rotating seat may shake due to the sudden stop of the seat rotation after the rotation reaches the position, and even may cause personal safety problems. Embodiments of the present application provide a rotating seat, which is at least used to solve this technical problem.

[0034] Please refer to Figures 1 - 5 , the rotating seat 10 provided by the embodiments of the present application includes a base 100, a rotating disk 200, a backrest 300, and a driving assembly 400. The rotating disk 200 is rotatably disposed on the base 100. The driving assembly 400 is disposed on the base 100. The driving assembly 400 is connected to the rotating disk 200 to drive the rotating disk 200 to rotate. The backrest 300 is connected to the rotating disk 200. A track groove 210 is provided on the rotating disk 200. Buffer slopes 211 are provided at both ends of the track groove 210. An elastic assembly 110 is provided on the base 100. The elastic assembly 110 is used to cooperate with the track groove 210.

[0035] It should be pointed out that a rotating shaft is provided on the base 100, and the rotating disk 200 rotates in cooperation with the rotating shaft; the driving component 400 is connected to the rotating disk 200 to drive the rotating disk 200 to rotate around the rotating shaft; the inner bottom wall of the track groove 210 is a transition plane 212, and the two ends of the transition plane 212 are respectively connected to the buffer slopes 211 at the two ends of each track groove 210. During the rotation of the rotating disk 200, the elastic component 110 will abut against the transition plane 212, the buffer slope 211 and one of the bottom surfaces of the rotating disk 200.

[0036] When the rotating seat 10 is in use, the driving component 400 drives the rotating disk 200 to rotate around the rotating axis, and the seat back 300 rotates synchronously with the rotating disk 200. During the rotation of the rotating disk 200, the elastic component 110 can abut against the transition plane 212, the buffer slope 211 and one of the bottom surfaces of the rotating disk 200. When the elastic component 110 transfers from abutting against the transition plane 212 to abutting against the buffer slope 211, the elastic component 110 will apply resistance to the rotating disk 200, so that the rotation speed of the rotating disk 200 decreases. At this time, the user will be prompted that the rotating seat 10 is about to rotate to the use state. When the elastic component 110 disengages from the buffer slope 211 and the rotating disk 200 stops rotating, the seat back 300 will not produce a large shake, thereby reducing the degree of shaking when the seat rotation stops, thereby ensuring the personal safety of the user.

[0037] In some optional embodiments, a plurality of track grooves 210 are arranged on the rotating disk 200 at intervals along its circumference, and the number of the elastic component 110 is one, and the elastic component 110 is used to cooperate with any one of the track grooves 210 .

[0038] During the rotation of the rotating disk 200, the elastic component 110 can cooperate with any one of the track grooves 210 on the rotating disk 200, that is, the elastic component 110 can abut against the transition plane 212 or the buffer slope 211 in any one of the track grooves 210. When the elastic component 110 transfers from abutting against the transition plane 212 in any one of the track grooves 210 to abutting against the buffer slope 211, the elastic component 110 will apply resistance to the rotating disk 200, so that the rotation speed of the rotating disk 200 decreases.

[0039] In some other optional embodiments, a plurality of elastic components 110 are disposed on the base 100 , the number of the track groove 210 is one, and the plurality of elastic components 110 are used to cooperate with the track groove 210 .

[0040] A plurality of elastic components 110 are arranged along the circumference of the rotating disk 200 . When any elastic component 110 is transferred from abutting against the transition plane 212 to abutting against the buffer slope 211 , the elastic component 110 will apply resistance to the rotating disk 200 , so that the rotation speed of the rotating disk 200 decreases.

[0041] In this embodiment, the buffer inclined plane 211 extends obliquely from the inner bottom wall of the track groove 210 towards the bottom surface of the rotating disk 200.

[0042] The buffer inclined plane 211 is arranged in the track groove 210. In the inclined direction of the buffer inclined plane 211, one end of the buffer inclined plane 211 is connected to one end of the transition plane 212, and the other end of the buffer inclined plane 211 is connected to the bottom surface of the rotating disk 200.

[0043] During the clockwise rotation of the rotating disk 200, the elastic component 110 will abut against the transition plane 212 after passing through the first buffer inclined plane 211 in the track groove 210, and then abut against the second buffer inclined plane 211 to decelerate the rotating disk 200; during the counterclockwise rotation of the rotating disk 200, the elastic component 110 will abut against the transition plane 212 after passing through the second buffer inclined plane 211, and then abut against the first buffer inclined plane 211 to decelerate the rotating disk 200.

[0044] In this embodiment, the driving component 400 includes a motor 410 and a first gear 420. The motor 410 is arranged on the base 100. The motor 410 is coaxially connected to the first gear 420. A second gear 220 is arranged on the rotating disk 200, and the first gear 420 and the second gear 220 cooperate with each other.

[0045] When it is necessary to drive the rotating disk 200 to rotate, start the motor 410. The motor 410 drives the first gear 420 to rotate, and the first gear 420 drives the second gear 220 and the rotating disk 200 to rotate synchronously.

[0046] In other embodiments, the driving component 400 is not limited to the cooperation mechanism of the motor 410 and the gear. For example, the driving component 400 includes a motor 410, a worm gear and a worm. The motor 410 is coaxially connected to the worm. The worm gear is arranged on the rotating disk 200, and the worm and the worm gear cooperate. When it is necessary to drive the rotating disk 200 to rotate, start the motor 410. The motor 410 drives the worm to rotate, and the worm drives the worm gear and the rotating disk 200 to rotate synchronously.

[0047] In this embodiment, the elastic component 110 includes a buffer elastic member 111 and a buffer pressing block 112 which are connected. The buffer elastic member 111 is arranged on the base 100. The buffer elastic member 111 is used to move the buffer pressing block 112 towards the rotating disk 200, and the buffer pressing block 112 is used to cooperate with the track groove 210.

[0048] Under the elastic action of the buffer elastic member 111, the buffer pressing block 112 can abut against one of the transition plane 212, the buffer inclined plane 211 and the bottom surface of the rotating disk 200.

[0049] During the rotation of the rotating disk 200, the buffer pressure block 112 can abut against one of the transition plane 212, the buffer slope 211 and the bottom surface of the rotating disk 200. When the buffer pressure block 112 is transferred from abutting against the transition plane 212 to abutting against the buffer slope 211, the buffer elastic member 111 applies resistance to the rotating disk 200 through the buffer pressure block 112, so that the rotation speed of the rotating disk 200 decreases. Therefore, when the buffer pressure block 112 is separated from the buffer slope 211 and the rotating disk 200 stops rotating, the chair back 300 will not produce a large shake, thereby reducing the degree of shaking when the seat stops rotating and ensuring the personal safety of the user.

[0050] It should be noted that the number of track grooves 210 can be determined according to the number of corresponding states when the rotating seat 10 is in use. When the buffer pressure block 112 enters the track groove 210, it represents that the rotating seat 10 is about to enter a certain use state. The reduction in the rotation speed of the motor 410 will reduce the rotational inertia generated by the stopping of the motor 410 when the rotating seat 10 is rotated into place, so that the rotating seat 10 reduces the degree of shaking of the seat back 300 due to the reduction in inertia, thereby improving the riding comfort and safety of the user.

[0051] In this embodiment, a receiving groove 120 is opened on the base 100, and a limiting column 121 is arranged in the receiving groove 120. The buffer elastic member 111 is a spring, and the spring is sleeved on the limiting column 121. One end of the spring abuts against the inner bottom wall of the receiving groove 120, and the other end of the spring abuts against the buffer pressure block 112.

[0052] The limiting column 121 serves to limit the spring to prevent the spring from deflecting. Under the elastic action of the spring, the buffer pressing block 112 can abut against one of the transition plane 212, the buffer slope 211 and the bottom surface of the rotating disk 200.

[0053] In other embodiments, the buffer elastic member 111 may also be an elastic member made of spring sheet or rubber.

[0054] In this embodiment, the track groove 210 is an arc-shaped groove.

[0055] When there are multiple track grooves 210, the multiple track grooves 210 are on the same circular path. When the buffer pressure block 112 moves into the track groove 210, the buffer pressure block 112 can abut against the transition plane 212 or the buffer slope 211. When the buffer pressure block 112 moves outside the track groove 210, that is, when the buffer pressure block 112 moves between two adjacent track grooves 210, the buffer pressure block 112 abuts against the bottom surface of the rotating disk 200.

[0056] In this embodiment, a connecting arm 230 is provided on the surface of the rotating plate 200 facing away from the base 100 , and the chair back 300 is connected to the connecting arm 230 .

[0057] The number of the connecting arms 230 is two, and the two connecting arms 230 are arranged in parallel. The chair back 300 is connected to the two connecting arms 230 at the same time. Among them, the connection manner between the chair back 300 and the connecting arms 230 can be bolt connection, snap connection, plug connection, etc., and no limitation is made thereto.

[0058] In this embodiment, the base 100 includes a base upper cover 130 and a base lower cover 140 which are connected to each other. The rotating disk 200 is rotatably arranged on the base lower cover 140, and the driving assembly 400 and the elastic assembly 110 are both arranged on the base lower cover 140.

[0059] It should be noted that the motor 410 is arranged on the base lower cover 140, the rotating shaft that is rotationally matched with the rotating disk 200 is arranged on the base lower cover 140, the accommodating groove 120 is formed on the base lower cover 140, and the base upper cover 130 is connected to the base lower cover 140 to play a role in covering components such as the motor 410.

[0060] In this embodiment, a control panel 131 for controlling the rotation of the rotating disk 200 is arranged on the base upper cover 130.

[0061] The control panel 131 has the function of controlling the rotating seat 10 to rotate clockwise and counterclockwise. The user can control the rotating seat 10 to rotate clockwise or counterclockwise by operating the buttons on the control panel 131. In fact, controlling the rotating seat 10 to rotate clockwise or counterclockwise means controlling the rotating disk 200 to rotate clockwise or counterclockwise.

[0062] In this embodiment, the rotating seat 10 further includes a controller, and the controller is electrically connected to the control panel 131 and the driving assembly 400 at the same time.

[0063] It should be noted that the controller is electrically connected to the control panel 131 and the motor 410 at the same time. When the user controls the rotating seat 10 to rotate clockwise by operating the buttons on the control panel 131, the motor 410 starts and drives the rotating disk 200 to rotate clockwise. When the user controls the rotating seat 10 to rotate counterclockwise by operating the buttons on the control panel 131, the motor 410 starts and drives the rotating disk 200 to rotate counterclockwise.

[0064] When the buffer pressure block 112 is transferred from the abutment transition plane 212 to the abutment buffer slope 211, the buffer pressure block 112 will apply resistance to the rotating disk 200 under the elastic action of the buffer elastic member 111, and the resistance gradually increases, and the user will be reminded that the rotating seat 10 is about to rotate to the use state. When the buffer pressure block 112 abuts the highest point of the buffer slope 211, the resistance is the largest. The greater the resistance applied by the buffer pressure block 112 to the rotating disk 200, the lower the rotation speed of the motor 410. When the power of the motor 410 reaches the set value, the controller can control and reduce the voltage of the motor 410, thereby reducing the rotation speed of the motor 410.

[0065] For example, Figure 6 The schematic diagram shows the rotating seat 10 being rotated to the use state. Figure 7 The schematic diagram shows the rotating seat 10 rotating to the use state.

[0066] The working principle of the rotating chair 10 provided in the embodiment of the present application is as follows: when using the rotating chair 10, the user controls the motor 410 to start by operating the control panel 131, and the motor 410 drives the first gear 420 to rotate, and the first gear 420 drives the second gear 220, the rotating disk 200, and the seat back 300 to rotate synchronously. During the rotation of the rotating disk 200, the buffer pressing block 112 can abut against one of the transition plane 212, the buffer inclined surface 211, and the bottom surface of the rotating disk 200 under the elastic action of the buffer elastic member 111. When the buffer pressing block 111 When the cushioning block 112 is transferred from the abutting transition plane 212 to the abutting buffer slope 211, the cushioning block 112 exerts resistance to the rotating disk 200 under the elastic action of the cushioning elastic member 111, so that the rotation speed of the rotating disk 200 decreases, and then the rotation speed of the motor 410 decreases. When the cushioning block 112 is separated from the cushioning slope 211 and the motor 410 stops rotating, the rotating seat 10 rotates to the use state, and the seat back 300 does not produce a large shake, which reduces the shaking degree of the seat when the rotation stops, improves the riding comfort of the user, and ensures the personal safety of the user.

[0067] In summary, the embodiment of the present application provides a rotating seat 10. During the use of the rotating seat 10, the driving component 400 drives the rotating disk 200 to rotate, and the seat back 300 rotates synchronously with the rotating disk 200. During the rotation of the rotating disk 200, the elastic component 110 can abut against the transition plane 212, the buffer slope 211 and one of the bottom surfaces of the rotating disk 200. When the elastic component 110 transfers from abutting the transition plane 212 to abutting the buffer slope 211, the elastic component 110 will apply a gradually increasing resistance to the rotating disk 200, so that the rotation speed of the rotating disk 200 and the motor 410 decreases, so that when the elastic component 110 disengages from the buffer slope 211 and the motor 410 stops rotating, the seat back 300 will not produce a large shake, thereby reducing the degree of shaking of the rotating seat 10 when it stops rotating.

[0068] The above is only a specific implementation of the present application, but the protection scope of the present application is not limited thereto. Any changes or substitutions that can be easily thought of by a person skilled in the art within the technical scope disclosed in the present application should be included in the protection scope of the present application. Therefore, the protection scope of the present application shall be based on the protection scope of the claims.
