Description

Technical Field

[0001] This application relates to the field of swing chairs, and more specifically, to an electrically driven swing chair. Background Technology

[0002] In the relevant technical field, swing chairs are a popular entertainment tool for children and other users. In order to enable swing chairs to swing automatically, a swing motor is often added to drive the swing chair to swing. Summary of the Invention

[0003] This application provides an electrically driven swing chair, which aims to provide adjustment feedback for the swing of the electrically driven swing chair, so that the swing range of the swing chair is always within a set range to meet the user's needs.

[0004] This application provides an electrically driven swing chair, including: a swing body, a driving device, a detection device, a control device, and an energy storage device. The swing body includes a support device and a load-bearing mechanism. The load-bearing mechanism is connected to the support device and can swing relative to the support device. The driving device is connected to the support device and is drively connected to the load-bearing mechanism. The detection device is connected to the support device and the driving device, and is used to detect the rotational speed of the driving device. The control device is electrically connected to the driving device and the detection device, and is used to adjust the rotational speed of the driving device according to the rotational speed of the driving device detected by the detection device. The energy storage device is electrically connected to the driving device and the control device.

[0005] Based on the above embodiments, a detection device detects the rotational speed of the drive device and feeds the detection result back to the control device. The control device uses the rotational speed to calculate the current swing speed of the bearing mechanism. When the swing speed calculated by the detection device exceeds a set range, the control device controls the rotational speed of the drive device to slow down, so that the swing speed of the bearing mechanism slows down until the swing speed of the bearing mechanism meets the set speed range, thus ensuring the user's riding safety. When the swing speed of the bearing mechanism calculated by the detection device is less than the set range, the control device controls the rotational speed of the drive device to speed up, so that the swing speed of the bearing mechanism speeds up until the swing speed of the bearing mechanism meets the set speed range, thus satisfying the user's set requirements.

[0006] In some embodiments, the drive device includes a reduction mechanism and a swing motor. The reduction mechanism is connected to the support device and has an output shaft that is connected to the load-bearing mechanism. The swing motor is connected to the reduction mechanism, and the rotating shaft of the swing motor is drivenly connected to the reduction mechanism.

[0007] Based on the above embodiments, the swing motor drives the reduction mechanism to move, and the reduction mechanism converts the rotational motion of the swing motor into swing motion, or the swing motor directly outputs swing motion, which is then transmitted to the bearing mechanism through the output shaft of the reduction mechanism, so that the bearing mechanism swings relative to the support device.

[0008] In some embodiments, the detection device includes a grating sensor and a test piece. The grating sensor is connected to a support device and electrically connected to a control device. The grating sensor has a detection position. The test piece is connected to the shaft of a swing motor and is partially disposed at the detection position.

[0009] Based on the above embodiments, the rotating shaft of the swing motor drives the test piece to rotate synchronously. The test piece rotates relative to the grating sensor at the detection position, thereby changing the working state of the grating sensor. This allows the grating sensor to measure the rotational speed of the test piece and calculate the rotational speed of the swing motor shaft. This facilitates the detection of the rotational speed of the swing motor shaft, thereby calculating the swing speed of the bearing mechanism. This ensures that the swing speed of the bearing mechanism is always within the set speed range, providing a guarantee for the user's riding safety and meeting the user's set requirements.

[0010] In some embodiments, the electrically driven swing chair also includes a multi-stage adjustment device, which is disposed on the support device and electrically connected to the control device for adjusting the swing amplitude and / or swing speed of the support mechanism.

[0011] Based on the above embodiments, a multi-stage adjustment device is used to adjust the swing amplitude and swing speed of the bearing mechanism in order to provide users with different riding experiences.

[0012] In some embodiments, the support device includes a housing with a receiving cavity, in which a drive device, a detection device, a control device, an energy storage device, and a multi-stage adjustment device are all disposed, with the multi-stage adjustment device partially exposed outside the receiving cavity.

[0013] Based on the above embodiments, the drive device, detection device, control device, energy storage device, and multi-stage adjustment device are all housed within the housing cavity. The housing protects the drive device, detection device, control device, energy storage device, and multi-stage adjustment device, ensuring that their operation is not disturbed by external factors. This provides a guarantee for the safety of the user riding the load-bearing mechanism. Furthermore, part of the multi-stage adjustment device protrudes outside the housing cavity, allowing the user to operate the multi-stage adjustment device and adjust the swing amplitude and swing speed of the load-bearing mechanism, providing the user with different riding experiences.

[0014] In some embodiments, the housing has an adjustment groove with an adjustment port at the bottom, through which a portion of the multi-stage adjustment device extends into the adjustment groove.

[0015] Based on the above embodiments, a portion of the multi-stage adjustment device extends into the adjustment groove from the adjustment port, allowing the portion of the multi-stage adjustment device to protrude from the receiving cavity. This facilitates the user's adjustment of the swing amplitude and swing speed of the bearing mechanism. Furthermore, since the portion of the multi-stage adjustment device protruding from the receiving cavity is located within the adjustment groove, the adjustment groove can be used to protect the multi-stage adjustment device, thereby reducing the probability of damage to the multi-stage adjustment device due to external impacts and extending the service life of the multi-stage adjustment device, thus extending the lifespan of the electric swing chair.

[0016] In some embodiments, the support device includes a housing having a receiving cavity and a light outlet communicating with the receiving cavity. The electrically driven swing chair also includes an indicator light disposed in the receiving cavity and facing the light outlet, and electrically connected to the control device to indicate the current operating status of the electrically driven swing chair.

[0017] Based on the above embodiments, users can determine the current operating status of the electric swing chair through the indicator lights, so that users can turn the electric swing chair on, off, or adjust it.

[0018] In some embodiments, the bearing mechanism includes a bearing part and a swing arm connected to the bearing part. The swing arm is connected to the output shaft of the drive device. The support device includes a housing, a first protective shell, and a second protective shell. The housing has a receiving cavity, in which the drive device, detection device, control device, energy storage device, and multi-stage adjustment device are all disposed. The first protective shell is disposed on the housing and has a mounting port facing the bearing part. The output shaft of the drive device passes through the housing and is located inside the first protective shell. The second protective shell is connected to the side of the swing arm away from the bearing part. The second protective shell is connected to the output shaft inside the first protective shell through the mounting port. Wherein, the angle between the central axis of the swing arm and the vertical direction is α, then the swing angle of the central axis of the swing arm is 2α. The central angle formed by the walls of the mounting ports on both sides of the swing axis of the second protective shell is β, and β satisfies: β≤360°-2α.

[0019] Based on the above embodiments, the output shaft of the drive device is protected by the first protective shell and the second protective shell. When β satisfies β≤360°-2α, it can ensure that the swing arm can swing at a large angle. Moreover, no matter how large the swing arm swings, there will be no circumferential opening between the second protective shell and the first protective shell, so as to prevent foreign objects from entering the first protective shell and the second protective shell from the opening, thereby providing a reliable guarantee for the stable operation of the electric drive swing chair. When β>360°-2α, the swing amplitude of the swing arm will be limited due to the excessively large central angle of the first protective shell, which will affect the adjustment of the swing amplitude of the bearing part by the multi-stage adjustment device.

[0020] In some embodiments, the support device includes a frame and a crossbeam, with the housing connected to the frame; the crossbeam passes through a first protective shell and is connected to the frame.

[0021] Based on the above embodiments, the support device and the crossbeam support the housing and the load-bearing mechanism so that the load-bearing mechanism can swing relative to the support device, and also provide a safety guarantee for the swing of the load-bearing mechanism.

[0022] In some embodiments, the drive device includes a reduction mechanism and a swing motor. The reduction mechanism has a housing and two connecting ends, both of which are exposed outside the housing. One connecting end is connected to a crossbeam, and the other connecting end is connected to the housing. The reduction mechanism also has an output shaft connected to a load-bearing mechanism. The swing motor is connected to the housing, and the rotating shaft of the swing motor is drively connected to the reduction mechanism.

[0023] Based on the above embodiments, two connecting ends are respectively connected to the housing and the crossbeam, so that the swing motor and the reduction mechanism are stably connected to the support device, so that the output shaft of the reduction mechanism can stably drive the movement of the bearing mechanism. The swing motor is connected to the housing of the drive device, so that the rotating shaft of the swing motor can be stably connected to the reduction mechanism.

[0024] In some embodiments, the second protective shell is provided with a clearance groove to avoid the crossbeam. With the swing axis of the second protective shell as the center, the central angle formed by the two opposite groove walls of the clearance groove is γ, which satisfies: γ≥360°-β+α.

[0025] Based on the above embodiments, when γ satisfies γ≥360°-β+α, the second protective shell will not collide with the crossbeam when swinging with the swing arm, thus ensuring the stability of the support device; when γ<360°-β+α, the second protective shell may collide with the crossbeam when swinging with the swing arm, thereby affecting the connection stability between the crossbeam and the support device, thus affecting the stability of the support device and posing a significant safety hazard.

[0026] An embodiment of this application provides an electrically driven swing chair, comprising: a swing body, a driving device, a detection device, a control device, and an energy storage device. The swing body includes a support device and a load-bearing mechanism, the load-bearing mechanism being connected to the support device and capable of swinging relative to the support device; the driving device being connected to the support device and being drively connected to the load-bearing mechanism; the detection device being connected to the support device and the driving device, for detecting the rotational speed of the driving device; the control device being electrically connected to the driving device and the detection device, for adjusting the rotational speed of the driving device according to the rotational speed of the driving device detected by the detection device; and the energy storage device being electrically connected to the driving device and the control device. The rotational speed of the drive unit is detected by a detection device, and the detection result is fed back to the control device. The control device uses the rotational speed to calculate the current swing speed of the load-bearing mechanism. When the swing speed calculated by the detection device exceeds the set range, the control device controls the rotational speed of the drive unit to slow down, so that the swing speed of the load-bearing mechanism is slowed down until the swing speed of the load-bearing mechanism is within the set speed range, thus ensuring the safety of the user. When the swing speed of the load-bearing mechanism calculated by the detection device is less than the set range, the control device controls the rotational speed of the drive unit to speed up, so that the swing speed of the load-bearing mechanism is increased until the swing speed of the load-bearing mechanism is within the set speed range, thus meeting the user's needs.

Detailed Implementation

[0030] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0031] In the relevant technical field, swing chairs are a popular recreational tool for children and other users. In order to enable the swing chair to swing automatically, a swing motor is often added to drive the swing chair to swing. However, due to the frictional resistance between the user, the electrically driven swing chair and the air, the swing speed of both the electrically driven swing chair and the user will gradually decrease, and thus cannot reach the swing speed set by the user.

[0032] To address the aforementioned technical problems, this application proposes an electrically driven swing chair that provides adjustment feedback for the swing of the chair, ensuring that the swing speed remains within a set range to meet the user's needs.

[0033] Please refer to Figure 1-3This application provides an electrically driven swing chair 1, including: a swing body 11, a drive device 12, a detection device 13, a control device 14, and an energy storage device 15. The swing body 11 includes a support mechanism 111 and a support device 112. The support mechanism 111 is connected to the support device 112 and can swing relative to the support device 112. The drive device 12 is connected to the support device 112 and is also connected to the support mechanism 111. The detection device 13 is connected to the support device 112 and the drive device 12, and is used to detect the rotational speed of the drive device 12. The control device 14 is electrically connected to the drive device 12 and the detection device 13, and is used to adjust the rotational speed of the drive device 12 according to the rotational speed of the drive device 12 detected by the detection device 13. The energy storage device 15 is electrically connected to the drive device 12 and the control device 14.

[0034] The carrying mechanism 111 can be configured as a tool with a riding function so that the user can ride on it and thus the user can swing relative to the support device 112 as the carrying mechanism 111 swings.

[0035] The support device 112 can be configured as a support device structure spliced ​​from tubular structures, used to support the bearing mechanism 111 and the user riding on the bearing mechanism 111, so that the user riding on the bearing mechanism 111 can swing relative to the support device 112.

[0036] The drive device 12 may include a swing motor 121 or a swing cylinder, etc., to provide power support for the swing of the bearing mechanism 111. The connection between the drive device 12 and the support device 112 may be, but is not limited to, screw connection, snap connection or adhesive connection. The drive device 12 and the bearing mechanism 111 may be connected by a transmission structure such as a coupling.

[0037] The detection device 13 may include a grating sensor 131 or other devices that can be used to detect the rotational speed of the drive device 12. The connection between the detection device 13 and the support device 112 may be, but is not limited to, screw connection, snap connection or welding.

[0038] The control device 14 may include a control circuit board and other electronic components for controlling the rotation speed of the drive device 12 and receiving detection signals from the detection device 13 to control the rotation speed of the drive device 12.

[0039] The energy storage device 15 may be configured as a battery, and the energy storage device 15 is electrically connected to the drive device 12 and the control device 14 to provide power support for the drive device 12 and the control device 14.

[0040] In this embodiment, the detection device 13 detects the rotational speed of the drive device 12 and feeds the detection result back to the control device 14. The control device 14 uses the rotational speed to calculate the current swing speed of the bearing mechanism 111. When the swing speed of the bearing mechanism 111 calculated by the detection device 13 exceeds the set range, the control device 14 controls the rotational speed of the drive device 12 to slow down, so that the swing speed of the bearing mechanism 111 slows down until the swing speed of the bearing mechanism 111 meets the set speed range, thus ensuring the user's riding safety. When the detection device 13 detects that the swing speed of the bearing mechanism 111 is less than the set range, the control device 14 controls the rotational speed of the drive device 12 to speed up, so that the swing speed of the bearing mechanism 111 speeds up until the swing speed of the bearing mechanism 111 meets the set speed range, thus satisfying the user's set requirements.

[0041] Please refer to Figure 1 and Figure 2 In one specific embodiment, the driving device 12 includes a swing motor 121 and a reduction mechanism 122. The reduction mechanism 122 is connected to the support device 112 and has an output shaft 1221, which is connected to the bearing mechanism 111. The swing motor 121 drives the output shaft 1221 of the reduction mechanism 122 to swing. The swing motor 121 is connected to the reduction mechanism 122, and the rotating shaft 1211 of the swing motor 121 is connected to the reduction mechanism 122 in a transmission connection. The reduction mechanism 122 converts the rotational motion of the swing motor 121 into swing motion, or oscillation. Motor 121 directly outputs oscillating motion, which is then transmitted to bearing mechanism 111 via output shaft 1221 of reduction mechanism 122, so that bearing mechanism 111 oscillates relative to support device 112. The connection between oscillating motor 121 and reduction mechanism 122 can be screwed, snap-fitted or glued. The connection between the rotating shaft 1211 of oscillating motor 121 and reduction mechanism 122 can be, but is not limited to, a transmission connection via coupling or other transmission structures. The connection between the output shaft 1221 of reduction mechanism 122 and bearing mechanism 111 can be, but is not limited to, a transmission connection via coupling or other transmission structures.

[0042] Please refer to Figure 1 and Figure 2In one specific embodiment, the detection device 13 includes a grating sensor 131 and a test piece 132. The grating sensor 131 is connected to the support device 112 and electrically connected to the control device 14. The grating sensor 131 has a detection position 1311. The test piece 132 is connected to the rotating shaft 1211 of the swing motor 121, and part of the test piece 132 is disposed on the detection position 1311. The rotating shaft 1211 of the swing motor 121 drives the test piece 132 to rotate synchronously. The test piece 132 rotates relative to the grating sensor 131 on the detection position 1311, causing the grating sensor 131 to rotate. The rotational speed of the tested component 132 can be measured, and the rotational speed of the shaft 1211 of the swing motor 121 can be calculated. This allows for the detection of the rotational speed of the shaft 1211 of the swing motor 121, thereby detecting the swing speed of the bearing mechanism 111. This ensures that the swing speed of the bearing mechanism 111 is always within the set speed range, providing a guarantee for the user's riding safety and meeting the user's set requirements. The connection method between the grating sensor 131 and the support device 112 can be, but is not limited to, screw connection, snap connection, or adhesive connection. The material of the tested component 132 can be plastic or metal and is opaque.

[0043] Please refer to Figure 1 and Figure 2 In another specific embodiment, the detection position 1311 can be a detection groove formed on the side of the photosensitive sensor near the test piece 132. The test piece 132 can be configured as a disc shape, and a portion of the test piece 132 is located within the detection groove. One of the two opposing groove walls of the detection groove is provided with a transmitter (not shown in the figure), and the other groove wall is provided with a receiver (not shown in the figure). The test piece 132 has multiple arc-shaped grooves 1321 and multiple blocking portions 1322. Adjacent arc-shaped grooves 1321 are separated by blocking portions 1322. The arc-shaped grooves 1321 and the blocking portions 1322 alternately pass through the detection groove; when the arc-shaped groove 1321 and the transmitter and the... When the receiver is aligned, it can receive the signal transmitted by the transmitter. When the shielding part 1322 is aligned with the receiver and the transmitter, the receiver cannot receive the signal transmitted by the transmitter. The rotational speed of the test piece 132 can be calculated by the time interval between two or more receivers receiving the transmitter signal. The swing speed of the bearing mechanism 111 can be calculated by the transmission ratio between the swing motor 121 and the bearing mechanism 111. The swing speed of the bearing mechanism 111 can then be adjusted to ensure that the swing speed of the bearing mechanism 111 is always within the set range, thus ensuring the user's riding safety and meeting the user's set requirements.

[0044] Please refer to Figure 1 and Figure 2In one specific embodiment, the electrically driven swing chair 1 further includes a multi-level adjustment device 16, which is disposed on the support device 112 and electrically connected to the control device 14. It is used to adjust the swing amplitude and swing speed of the support mechanism 111 to provide users with different riding experiences. The multi-level adjustment device 16 can be made of plastic to prevent it from becoming electrified. The multi-level adjustment device 16 can be an operation button or other electronic components used to send control signals to the control device 14.

[0045] Please refer to Figure 1-3 In another specific embodiment, the multi-stage adjustment device 16 can be configured as an adjustment wheel. The multi-stage adjustment device 16 is rotatably connected to the support device 112 and electrically connected to the control device 14. The rotation of the multi-stage adjustment device 16 changes the resistance value of the resistor connected to it. Different resistance values ​​correspond to different adjustment levels. Different adjustment levels cause the swing motor 121 to have different rotation speeds, so as to change the swing speed of the bearing mechanism 111.

[0046] Please refer to Figure 1-3 In one specific embodiment, the support device 112 includes a housing 1121 with a receiving cavity 1122. The drive device 12, detection device 13, control device 14, energy storage device 15, and multi-stage adjustment device 16 are all disposed within the receiving cavity 1122. The housing 1121 protects the drive device 12, detection device 13, control device 14, energy storage device 15, and multi-stage adjustment device 16, ensuring that their operation is not disturbed by external factors. This provides safety for the user riding the support mechanism 111. Furthermore, a portion of the multi-stage adjustment device 16 protrudes outside the receiving cavity 1122, facilitating user operation of the multi-stage adjustment device 16 to adjust the support mechanism. The swing amplitude and / or swing speed of mechanism 111 provide users with different riding experiences. The shell 1121 can be made of plastic or metal. In this embodiment, the shell 1121 is preferably made of plastic to prevent it from becoming electrically charged. The shell 1121 can include an inner shell 1123 and an outer shell 1124. The inner shell 1123 and the outer shell 1124 can be injection molded separately. The inner shell 1123 is connected to the support device 112. The connection method can be screwed, snap-fit, or glued. The drive device 12, detection device 13, control device 14, energy storage device 15, and multi-stage adjustment device 16 are all connected to the inner shell 1123. The connection method can be screwed, snap-fit, or glued. Then, the outer shell 1124 is connected to the inner shell 1123. The connection method can be screwed, snap-fit, or glued.

[0047] Please refer to Figure 1 , Figure 3 and Figure 4 In another specific embodiment, the housing 1121 has an adjustment groove 1125, and the bottom of the adjustment groove 1125 has an adjustment port 1126. A portion of the multi-stage adjustment device 16 extends into the adjustment groove 1125 through the adjustment port 1126, which allows a portion of the multi-stage adjustment device 16 to protrude from the receiving cavity 1122, so that the user can adjust the swing amplitude and / or swing speed of the bearing mechanism 111. Moreover, the portion of the multi-stage adjustment device 16 protruding from the receiving cavity 1122 is located in the adjustment groove 1125, which can be used to protect the multi-stage adjustment device 16, thereby reducing the probability of the multi-stage adjustment device 16 being damaged by external impacts, extending the service life of the multi-stage adjustment device 16, and thus extending the service life of the electric drive swing chair 1.

[0048] Please refer to Figure 1 , Figure 3 and Figure 4 In one specific embodiment, the housing 1121 has a light outlet 1127 communicating with the receiving cavity 1122. The electric swing chair 1 also includes an indicator light 17, which is disposed in the receiving cavity 1122 and facing the light outlet 1127. The indicator light 17 is electrically connected to the control device 14 and is used to indicate the current operating status of the electric swing chair 1 so that the user can turn the electric swing chair 1 on, off or adjust it.

[0049] Please refer to Figure 1 , Figure 2 and Figure 5In one specific embodiment, the supporting mechanism 111 includes a supporting part 1111 and a swing arm 1112 connected to the supporting part 1111. The swing arm 1112 is connected to the output shaft 1221 of the driving device 12. The supporting device 112 also includes a first protective shell 113 and a second protective shell 114. The first protective shell 113 is disposed on the housing 1121 and has a mounting opening 1131 facing the supporting part 1111. The output shaft 1221 of the driving device 12 passes through the housing 1121 and is located inside the first protective shell 113. The second protective shell... 114 is connected to the side of the swing arm 1112 away from the bearing part 1111. The second protective shell 114 is connected to the output shaft 1221 inside the first protective shell 113 via the mounting port 1131. The first protective shell 113 and the second protective shell 114 protect the output shaft 1221 of the drive device 12. The angle between the central axis of the swing arm 1112 and the vertical direction is α, and the swing angle of the central axis of the swing arm 1112 is 2α. The mounting port 1131 on both sides of the swing axis of the second protective shell 114 is the center of the circle. The central angle formed is β. When β satisfies β≤360°-2α, it can ensure that the swing arm 1112 can swing at a large angle, and no matter how large the swing angle of the swing arm 1112 is, there will be no circumferential opening between the second protective shell 114 and the first protective shell 113, so as to prevent foreign objects from entering the first protective shell 113 and the second protective shell 114 from the opening, thereby providing a reliable guarantee for the stable operation of the electrically driven swing chair 1. When β>360°-2α, the swing amplitude of the swing arm 1112 will be limited because the central angle of the first protective shell 113 is too large. The degree of adjustment affects the adjustment of the swing amplitude of the bearing 1111 by the multi-stage adjustment device 16; wherein, the first protective shell 113 and the second protective shell 114 can both be made of rigid plastic, the first protective shell 113 can be integrally formed with the shell 1121, the connection method between the second protective shell 114 and the swing arm 1112 can be, but is not limited to, screwed, snap-fit ​​or glued, the swing arm 1112 can be set as a rod, its material can be metal, and the bearing 1111 can be spliced ​​from a metal frame for the user to sit on, so that the user can swing with the bearing 1111. In a specific embodiment, the angle α between the central axis of the swing arm 1112 and the vertical direction can be 10°, 20° or 30°.

[0050] Please refer to Figure 1 and Figure 2In one specific embodiment, the support device 112 includes a support device 115 and a crossbeam 116. The housing 1121 is connected to the support device 115. The end of the crossbeam 116 passes through the first protective shell 113 and is connected to the support device 115. The support device 115 and the crossbeam 116 support the housing 1121 and the load-bearing mechanism 111, so that the load-bearing mechanism 111 can swing relative to the support device 115, and also provide a safety guarantee for the swing of the load-bearing mechanism 111. The crossbeam 116 can be made of metal tubing, and the support device 115 can include a front leg 1151 and a rear leg 1151. The feet 1152, front feet 1151, and rear feet 1152 can all be formed by bending metal tubes into a "U" shape. The open ends of the front feet 1151 and rear feet 1152 are close to each other and connected. The connection method can be, but is not limited to, screwing, snapping, or gluing. The sides of the front feet 1151 and rear feet 1152 that are far apart from each other are set at an angle. The crossbeam 116 is located at the open ends of the front feet 1151 and rear feet 1152. The connection method between the crossbeam 116 and the support device 115 can be, but is not limited to, screwing, snapping, or gluing. The housing 1121 is connected to the open ends of the front feet 1151 and rear feet 1152. In this embodiment, the front feet 1151 and rear feet 1152 can be connected through the housing 1121, and the crossbeam 116 can also be connected to the housing 1121 to reduce the impact of the front feet 1151, rear feet 1152, and crossbeam 116 on the drive device 12.

[0051] Please refer to Figure 1-3 The reduction mechanism 122 has a housing 1222 and two connecting ends 1223. Both connecting ends 1223 are exposed outside the housing 1222. One connecting end 1223 is connected to the crossbeam 116, and the other connecting end 1223 is connected to the housing 1121, so that both the swing motor 121 and the reduction mechanism 122 can be stably connected to the housing 1121 of the support device 112, so that the output shaft 1221 of the reduction mechanism 122 can stably drive the bearing mechanism 111 to move. The swing motor 121 is connected to the housing 1222, so that the rotating shaft 1211 of the swing motor 121 can be stably connected to the reduction mechanism 122. The connection method between the two connecting ends 1223 and the crossbeam 116 and the housing 1121 can be, but is not limited to, screwed, snap-fit, or glued. The connection method between the swing motor 121 and the housing 1222 can be, but is not limited to, screwed, snap-fit, or glued, as long as the requirement of stable connection between the rotating shaft 1211 of the swing motor and the reduction mechanism 122 is met.

[0052] Please refer to Figure 1 In another specific embodiment, a rubber sleeve 1161 is also provided in the middle of the crossbeam 116. The connection between the rubber sleeve 1161 and the crossbeam 116 can be, but is not limited to, screw connection, snap connection or adhesive connection, so that the user can grab the rubber sleeve 1161 to move the electric swing chair 1.

[0053] Please refer to Figure 1 and Figure 5 In one specific embodiment, the second protective shell 114 is provided with a clearance groove 1141 to avoid the crossbeam 116. With the swing axis of the second protective shell as the center, the central angle formed by the two opposite groove walls of the clearance groove 1141 is γ. When γ satisfies γ≥360°-β+α, the second protective shell 114 will not collide with the crossbeam 116 when swinging with the swing arm 1112, thus ensuring the stability of the support device 112. When γ<360°-β+α, the second protective shell 114 may collide with the crossbeam 116 when swinging with the swing arm 1112, thereby affecting the connection stability between the crossbeam 116 and the support device 115, thus affecting the stability of the support device 112 and posing a significant safety hazard.
