The present invention will be described in detail below with reference to specific embodiments shown in the drawings. These embodiments are not intended to limit the invention and structural, methodological, or functional modifications of these embodiments that may be made by one of ordinary skill in the art are included within the scope of the invention.

The invention provides a multi-section ergonomic bionic seat which is suitable for an application scene of providing hand support when a user takes, and can effectively solve the problem that the user experience is poor due to the fact that a handrail body cannot be adjusted forwards and backwards in the prior art.

Referring to fig. 1 to 4, in the present embodiment, the multi-stage ergonomic bionic seat includes a seat plate 1, a back plate 2, a armrest connection assembly 3, an armrest support assembly 4, and an armrest body 5.

An inner tub 101 is provided at the rear end of the seat plate 1, and an inner rod 102 is provided in the inner tub 101. The back plate 2 is positioned at the rear end of the seat plate 1, and the lower end of the back plate 2 is inserted into the inner tub 101 and is rotatably connected with the seat plate 1 around the inner rod 102. The upper end of the armrest connecting component 3 is in sliding connection with the backup plate 2, and the lower end is hinged with the seat plate 1. The lower end of the armrest support assembly 4 is mounted on the seat plate 1. The rear end of the armrest body 5 is hinged with the armrest connecting component 3, and the front end extends to the upper part of the armrest supporting component 4 and is connected with the armrest supporting component 4 in a front-back sliding way.

It should be noted that, when sitting, the armrest plate 2 is rotated forward relative to the seat plate 1, and at this time, the armrest connecting assembly 3 slides upward relative to the armrest plate 2 and pushes the armrest body 5 forward synchronously, so that the armrest body 5 slides forward relative to the armrest support assembly 4, so as to provide forward hand support for the user in a sitting posture;

when lying and sleeping, the leaning board 2 is rotated backwards relative to the seat board 1, at the moment, the armrest connecting assembly 3 slides downwards relative to the leaning board 2 and synchronously pulls the armrest body 5 backwards, so that the armrest body 5 slides backwards relative to the armrest supporting assembly 4, and the armrest body provides back hand support for a user in a sitting posture;

therefore, the multi-section ergonomic bionic seat provided by the invention can effectively solve the problem that the armrest body 5 cannot be adjusted back and forth in the prior art, and is beneficial to improving user experience.

Optionally, a first guiding chute 201 is provided on the side of the back plate 2. The armrest connection assembly 3 includes a slide bar 301, a male bar 302, and a connection frame 303.

One end of the slide bar 301 is inserted into the first guiding chute 201 and slides up and down along the first guiding chute 201 relative to the back plate 2. The protruding rod 302 is fixedly arranged on the side surface of the seat board 1. The upper end of the connecting frame 303 is provided with an upper via hole for the sliding rod 301 to pass through, and the lower end is provided with a lower via hole for the protruding rod 302 to pass through.

It can be appreciated that when the back of the user leans back against the back plate 2, the back plate 2 will rotate backward relative to the seat plate 1, so that the slide rod 301 slides down along the first guiding chute 201;

similarly, when the user rotates the back plate 2 forward relative to the seat plate 1, the slide rod 301 slides upward along the first guide chute 201.

Further, a damping fin 202 extending along the length direction of the first guiding chute 201 and sliding through the sliding rod 301 is disposed in the first guiding chute 201;

an adjusting nut 304 is sleeved on the sliding rod 301 in a threaded manner, and the adjusting nut 304 is located between the backup plate 2 and the connecting frame 303.

It should be noted that, the damping fin 202 slides through the sliding rod 301, that is, the frictional resistance received by the sliding rod 301 when sliding up and down along the first guiding chute 201 is increased to a certain extent, so as to prevent the user from being frightened due to too fast backward rotation speed of the back plate 2 when the user leans backward against the back plate 2.

Further, the adjusting nut 304 is turned to adjust the frictional resistance between the slide rod 301 and the damping fin 202, thereby adjusting the backward rotation speed of the backup plate 2. For example, by moving the adjustment nut 304 in a direction approaching the back plate 2, the frictional resistance between the slide rod 301 and the damper 202 increases, and the speed of the back plate 2 rotating backward decreases; conversely, the adjusting nut 304 is moved in a direction approaching the connecting frame 303, the frictional resistance between the slide rod 301 and the damper 202 is reduced, and the backward rotation speed of the backup plate 2 is increased.

In this embodiment, the armrest support assembly 4 includes a support plate 401, a carriage 402, a spring 403, and a belt 404.

The lower end of the supporting plate 401 is fastened to the side of the seat plate 1, and the upper end is slidably connected to the armrest body 5. The sliding frame 402 is installed in the supporting plate 401 and is connected with the supporting plate 401 in a vertical sliding manner. The spring 403 is mounted below the carriage 402, and is used for driving the carriage 402 to slide upwards relative to the support plate 401. One end of the belt 404 is fixedly connected to the sliding frame 402, and the other end sequentially bypasses the bottom surface and the top surface of the supporting plate 401 and is fixedly connected to the armrest body 5.

It can be understood that when the user needs to lie and sleep, when the connecting frame 303 pulls the armrest body 5 backward, the armrest body 5 pulls the belt 404 backward, so that the belt 404 pulls the sliding frame 402 downward, and at this time, the upward elastic force of the spring 403 can provide a certain buffer to prevent the back plate 2 from rotating backward too fast;

when the user needs to sit, the connecting frame 303 pushes the armrest body 5 forward, and simultaneously, the spring 403 pushes the sliding frame 402 upward, so as to drive the belt 404 to pull the armrest body 5 forward, thereby reducing the effort required by the user.

Further, a second guide chute 501 is provided at the bottom of the armrest body 5, into which the top of the support plate 401 is inserted.

In this embodiment, the top surface of the inner tank 101 is provided with an inclined surface 1011, and the lower end of the backup plate 2 is provided with an arc-shaped plate 203 hinged with the inner rod 102. The ramp 1011 is configured to abut against the top surface of the arc-shaped plate 203, so as to limit the backup plate 2 from continuing to rotate backwards relative to the seat plate 1.

Further, a reset pushing frame 6 sliding back and forth relative to the seat board 1 is provided at the bottom of the seat board 1, and the arc-shaped plate 203 is fixedly provided with a reset baffle 204 extending to be arranged opposite to the reset pushing frame 6.

Specifically, when the user leans backward, the armrest 2 rotates backward, and the reset baffle 204 pushes the reset pushing frame 6 forward, so that the front end of the reset pushing frame 6 protrudes slightly from the front end of the seat plate 1;

when the sitting state needs to be switched, the reset pushing frame 6 is pushed backwards, so that the rear end of the reset pushing frame 6 pushes the reset baffle 204 backwards, and the reset baffle 204 drives the whole leaning board 2 to rotate forwards, so that the sitting state is switched.

Optionally, a supporting frame 7 is further arranged at the bottom of the seat board 1.

To sum up, the multi-section ergonomic bionic seat provided in this embodiment sets up handrail body 5 on handrail coupling assembling 3 and handrail supporting component 4 for handrail body 5 can take place corresponding displacement along with the front and back state of backup plate 2, and then solves the problem that handrail body 5 can't adjust from beginning to end among the prior art, improves user experience.

It should be understood that although the present disclosure describes embodiments, not every embodiment is provided with a separate embodiment, and that this description is for clarity only, and that the skilled artisan should recognize that the embodiments may be combined as appropriate to form other embodiments that will be understood by those skilled in the art.

The above list of detailed descriptions is only specific to practical embodiments of the present invention, and they are not intended to limit the scope of the present invention, and all equivalent embodiments or modifications that do not depart from the spirit of the present invention should be included in the scope of the present invention.
