Description

Technical Field

[0001] This utility model relates to chairs, specifically to a rocking chair that can automatically rock. Background Technology

[0002] A rocking chair is a common type of chair. It is used by applying a certain force to make the chair rock. Traditional rocking chairs typically require the user to place their feet on the ground and rely on the reaction force of their body to rock, or the user to sway their body to change their center of gravity. After a certain period of rocking, the amplitude of the rocking gradually decreases until it stops, requiring the user to place their feet on the ground again to apply force and make the chair rock. This is relatively strenuous. Furthermore, traditional rocking chairs only provide a basic rocking experience, their function is limited, and the overall user experience is poor. Utility Model Content

[0003] In view of the deficiencies in the prior art, the technical problem to be solved by this utility model is to provide an automatically rocking chair for solving the above-mentioned problems.

[0004] Therefore, this utility model is implemented using the following solution:

[0005] An automatically rocking rocking chair includes a rocking chair body, characterized in that: the rocking chair body has a first swing frame and a second swing frame arranged left and right at the corresponding lower leg positions, the user's lower leg positions can rest on the first and second swing frames, one end of the first and second swing frames is hinged to the rocking chair body, and also includes a swing drive component, the swing drive component can drive the first and second swing frames to swing, when the swing drive component drives the first and second swing frames to swing asynchronously, the rocking chair body basically remains stationary, when the swing drive component drives the first and second swing frames to swing synchronously, the entire rocking chair body is driven to swing by changing the center of gravity.

[0006] The swing drive assembly includes a first motor, the output end of which is connected to a drive shaft. One end of the drive shaft is connected to one end of a first swing arm. The other end of the first swing arm is hinged to one end of a first connecting rod. The other end of the first connecting rod is hinged to a first swing frame. The other end of the drive shaft is connected to one end of a second swing arm. The other end of the second swing arm is hinged to one end of a second connecting rod. The other end of the second connecting rod is hinged to a second swing frame.

[0007] A first slide rod is slidably disposed inside the first connecting rod, and one end of the first slide rod is hinged to the first swing frame. A second slide rod is slidably disposed inside the second connecting rod, and one end of the second slide rod is hinged to the second swing frame. Limiting components are provided for the first and second slide rods.

[0008] The limiting assembly includes a first limiting post disposed on a first sliding rod and a second limiting post disposed on a second sliding rod. The first connecting rod is provided with a first limiting groove through which the first limiting post passes, and the first limiting post abuts against both sides of the first limiting groove. The second connecting rod is provided with a second limiting groove through which the second limiting post passes, and the second limiting post abuts against both sides of the second limiting groove.

[0009] It also includes an adjustment frame, one end of which is hinged to the rocking chair body. The first motor is mounted on the adjustment frame, and a locking component is provided corresponding to the adjustment frame.

[0010] The rocking chair body is equipped with a second motor, the output end of which is connected to a rotating shaft. The rotating shaft is connected to one end of a third swing arm, the other end of which is hinged to one end of a third connecting rod, the other end of which is hinged to a fourth swing arm, one end of which is hinged to the rocking chair body, and the other end of which is equipped with a roller that can rest against the ground.

[0011] The outer wall of one end of the drive shaft has a first transmission pin and a second transmission pin extending outward, and the outer wall of the other end has a third transmission pin extending outward. The first swing arm is provided with a first transmission step and a second transmission step, and the second swing arm is provided with a third transmission step and a fourth transmission step. The first transmission pin abuts against the first transmission step, the second transmission pin abuts against the second transmission step, and the third transmission pin can abut against either the third or the fourth transmission step.

[0012] The second swing arm is connected to the drive shaft (11) with a first gear. The first gear meshes with a second gear on the transmission shaft. A first transmission sleeve is connected to the first gear. The first transmission sleeve is provided with a fifth transmission step and a sixth transmission step that can abut against the third transmission pin. The transmission shaft is connected to one end of the second swing arm.

[0013] The aforementioned technical solution provides an automatically rocking chair with first and second swing frames for users to place their lower legs. When the swing drive component drives the first and second swing frames to swing asynchronously, the legs can swing alternately back and forth, achieving leg relaxation. During this alternating swing, the chair's center of gravity remains unchanged, keeping the chair stationary. When the swing drive component drives the first and second swing frames to swing synchronously, the legs swing synchronously back and forth, again achieving leg relaxation. During this process, the chair's center of gravity continuously shifts, generating a rocking force to achieve automatic rocking. This eliminates the need to step on the ground or shake the body to rock the chair, providing a better user experience. Attached Figure Description

[0025] As shown in the figure, the present invention discloses an automatically rocking rocking chair, including a rocking chair body 1. The rocking chair body 1 has a first swing frame 2 and a second swing frame 4 arranged left and right at the corresponding lower leg positions. The user's lower legs can rest on the first and second swing frames. One end of the first and second swing frames is hinged to the rocking chair body 1. The invention also includes a swing drive assembly, which can drive the first and second swing frames to swing. When the swing drive assembly drives the first and second swing frames to swing asynchronously, the rocking chair body 1 remains basically stationary. When the swing drive assembly drives the first and second swing frames to swing synchronously, the entire rocking chair body 1 is driven to swing by changing the center of gravity.

[0026] Furthermore, the swing drive assembly includes a first motor 10, the output end of which is connected to a drive shaft 11. One end of the drive shaft 11 is connected to one end of a first swing arm 13, the other end of the first swing arm 13 is hinged to one end of a first connecting rod 14, the other end of the first connecting rod 14 is hinged to a first swing frame 2, the other end of the drive shaft 11 is connected to one end of a second swing arm 16, the other end of the second swing arm 16 is hinged to one end of a second connecting rod 17, and the other end of the second connecting rod 17 is hinged to a second swing frame 4. With this structure, by controlling the first motor 10 to drive the drive shaft 11 to rotate, and through the swing arm and connecting rod structure for transmission, the first and second swing frames can be driven to swing back and forth, causing the user's legs to rise and fall back and forth.

[0027] Furthermore, a first slide rod 20 is slidably disposed within the first connecting rod 14, one end of which is hinged to the first swing frame 2. A second slide rod is slidably disposed within the second connecting rod 17, one end of which is hinged to the second swing frame 4. Limiting components are provided corresponding to the first and second slide rods. The limiting components include a first limiting post 19 disposed on the first slide rod 20 and a second limiting post disposed on the second slide rod. The first connecting rod 14 is provided with a first limiting groove 15 through which the first limiting post 19 passes, and the first limiting post 19 abuts against both sides of the first limiting groove 15. The second connecting rod is provided with a second limiting groove through which the second limiting post passes, and the second limiting post abuts against both sides of the second limiting groove. This design incorporates a sliding rod transmission structure. During normal use, due to the squeezing force of the first and second swing frames, the limiting posts on the first and second sliding rods are always pressed tightly against one side of the first and second limiting grooves 15. There is no relative movement between the sliding rod and the connecting rod. The connecting rod and the sliding rod work together to drive the swing frame to swing, ensuring the stability of the transmission. When the user's hands, feet, or other parts are inserted between the swing frame and the rocking chair body, or when there is another object between the swing frame and the rocking chair body 1, when the swing frame swings down and contacts it, the sliding rod will slide within the connecting rod due to the reverse force, preventing the swing frame from continuing to move and squeezing the obstacle, thus avoiding damage to the human body or objects and effectively improving its safety during use.

[0028] Furthermore, it also includes an adjustment frame 12, one end of which is hinged to the rocking chair body 1. The first motor 10 is mounted on the adjustment frame 12, and a locking component is provided corresponding to the adjustment frame. By adopting the above structure, when the adjustment frame 12 swings, it drives the first motor 10, the swing arm, and the connecting rod structure to move synchronously, thereby driving the first and second swing frames to swing and adjusting their overall angle so that they can be adjusted to the required angle position before swinging. The locking component can use fasteners to lock the adjustment frame 12, or it can use a common rotary locking structure composed of a turntable, a self-locking pin, and a self-locking spring. This is existing technology and not an innovation of this application, so its specific structure and principle will not be described in detail.

[0029] Furthermore, a second motor 5 is installed on the rocking chair body 1. The output end of the second motor 5 is connected to a rotating shaft, which is connected to one end of a third swing arm 6. The other end of the third swing arm 6 is hinged to one end of a third connecting rod 7, and the other end of the third connecting rod 7 is hinged to a fourth swing arm 8. One end of the fourth swing arm 8 is hinged to the rocking chair body 1, and the other end of the fourth swing arm 8 is equipped with a roller 9 that can rest against the ground. With the above structure, when the legs are not raised or lowered, the second motor 5 can be controlled to swing, and the fourth swing arm 8 can be swung through the swing arm and connecting rod structure, thereby pressing against the ground and causing the entire rocking chair to sway. In addition, when the rocking chair is not swaying, the angle of the fourth swing arm swinging to a fixed support point can be controlled, so that the roller 9 rests against the ground, limiting the angle position of the rocking chair body and keeping the rocking chair stationary.

[0030] Furthermore, the outer wall of one end of the drive shaft 11 has a first transmission pin 21 and a second transmission pin 22 extending outward, and the outer wall of the other end has a third transmission pin 23 extending outward. The first swing arm 13 is provided with a first transmission step 24 and a second transmission step 25, and the second swing arm 16 is provided with a third transmission step 26 and a fourth transmission step 27. The first transmission pin 21 abuts against the first transmission step 24, the second transmission pin 22 abuts against the second transmission step 25, and the third transmission pin 23 can abut against the third or fourth transmission step. By adopting the above structure, the drive shaft 11 rotates and, through the first and second transmission pins, presses against the first and second transmission steps, causing one end of the first swing arm 13 to rotate, thereby causing the first swing frame 2 to swing. Additionally, the third transmission pin 23 presses against the third or fourth transmission step to cause the second swing arm 16 to swing, thereby causing the second swing frame 4 to swing. In this transmission structure, regardless of whether the motor rotates forward or backward, the first and second transmission pins can immediately drive the first swing arm 13 to rotate, causing the first swing frame 2 to swing. The third transmission pin 23 only needs to engage with the third or fourth transmission step. The second swing arm 16 will only rotate when the steps abut against each other. Utilizing this characteristic, when switching between synchronous and asynchronous movements of the first and second swing frames, simply reverse the motor. The first swing frame 2 will continue to swing, while the second swing frame 4 will stop swinging and wait for the third transmission pin 23 to rotate 180 degrees (depending on the relative angle of the third and fourth transmission steps) to abut against the third and fourth transmission steps before the second swing arm 16 rotates, causing the second swing frame 4 to swing. This achieves the synchronous or asynchronous switching between the first and second swing frames. With this structure, only a single motor is needed to switch between synchronous and asynchronous swinging of the first and second swing frames. Alternatively, separate motors can be used for each swing frame to control their swinging, and a controller can be used to control the movement of the corresponding motors, also achieving the synchronous or asynchronous swinging switching between the first and second swing frames.

[0031] Furthermore, a first gear 28 is provided at the connection end between the second swing arm 16 and the drive shaft 11. The first gear 28 meshes with a second gear 29 provided on the transmission shaft 31. A first transmission sleeve 30 is connected to the first gear 28. The first transmission sleeve 30 is provided with a fifth transmission step 32 and a sixth transmission step 33 that can abut against the third transmission pin 23. The transmission shaft 31 is connected to one end of the second swing arm 16. By adopting the above structure, the transmission of the second swing arm 16 can be realized through the gear set, making the transmission between the two more stable. This avoids the problem of the second swing frame 4 falling rapidly due to lack of support when swinging down, ensuring that the second swing frame 4 can reciprocate within a reasonable speed range, making its movement more stable, and thus providing a better user experience.

[0032] The working principle of this utility model is as follows: When the user lies back on the rocking chair body 1 with their legs placed on the first and second swing frames respectively, the first motor 10 is activated, and through the swing arm and linkage structure, it drives the first and second swing frames and the user's legs to swing asynchronously, relaxing the legs. At this time, the center of gravity of the rocking chair body 1 does not change, so the rocking chair body 1 remains basically in a stationary state. When the first motor 10 is reversed, the transmission structure drives the first and second swing frames and the user's legs to swing synchronously, which can also relax the legs. During this process, the center of gravity of the rocking chair body 1 will continuously change, thereby generating rocking force to realize the automatic rocking of the chair.

[0033] This invention features a structure with first and second swing frames for users to place their lower legs. When the swing drive component moves the first and second swing frames, it causes the user's legs to swing and relax. It can also switch between synchronous and asynchronous swinging of the first and second swing frames and synchronous swinging. The rocking chair automatically rocks by changing the center of gravity, eliminating the need to step on the ground or shake the body to rock the chair, thus providing a better user experience.
