If the controller receives a read-write mode opening signal at night, the controller can adjust the relative position between the small table plate 7 and a user according to the same steps in the previous section, and can also adjust the direction of light of the light source output by the lampshade 12 entering the small table plate 7, when the direction of the light source output by the lampshade 12 entering the small table plate 7 is adjusted, the third motor 9 can be controlled to rotate firstly to drive the third electric telescopic rod 10 and the lampshade 12 to rotate from vertical downward to vertical upward, then the third electric telescopic rod 10 is controlled to extend to a determined third telescopic length, and the fourth motor 11 is controlled to rotate to a determined rotation angle to drive the lampshade 12 to rotate, so that the adjustment of the incident direction of the light source output by the lampshade 12 relative to the small table plate 7 is completed.
After all adjustments are completed, the controller firstly determines the original number of the first pressure sensors in the first area, then judges whether the difference value between the current number of the first pressure sensors detecting the pressure in the first pressure sensor array 13 and the original number is larger than a corresponding preset value, if so, judges whether the first pressure sensors are currently in a night read-write mode or a day read-write mode, if so, controls the lamp in the lampshade 12 to be turned off, and if so, controls the first motor to rotate towards the direction away from the user by a preset angle. In addition, after the chair is used, a user can press a closing button arranged on the outer side of the first armrest or the second armrest, and the controller receives a closing signal and controls the components of the chair to reset.
According to the invention, the first pressure sensor array is arranged on the chair back, the height of the user and the sitting position of the user are determined according to the pressure information detected by the first pressure sensor array, and then the relative position between the small table board and the user is adjusted according to the height of the user and the sitting position of the user, so that the relative position between the small table board and the user can be fixed on the premise of not touching the body of the user, the user has high experience degree, and the relative position between the small table board and the user is adjusted without manual operation, the whole process is automatically carried out, and the degree of automation of the invention is high. In addition, the relative position between the small table plate and the user is adjusted based on the actual height and the sitting position of the user, so that the relative position between the small table plate and the user can be scientifically determined, the anti-myopia chair is suitable for anti-myopia requirements of different users, and the personnel application range and the anti-myopia effect of the chair are improved.
The invention is divided into a daytime read-write mode and an evening read-write mode, can be suitable for reading and writing in daytime and evening, and improves the environment application range of the chair; through with daytime reading and writing button and evening reading and writing button set up respectively in the outside that corresponds the handrail, can avoid the user to cause the maloperation in the use. The trunk of the user may move during reading and writing, and the hand movement during reading and writing may cause the trunk to be loosely attached to the first pressure sensor, but this does not mean that the trunk of the user is bent. According to the invention, after the adjustment is completed, the current number of the first pressure sensors detecting the pressure in the first pressure sensor array is counted, and when the difference value between the current number and the original number of the first pressure sensors in the determined first area is greater than the corresponding preset value, the humpback condition of the user is determined, so that a certain relieving free space can be provided for the user, the user is prevented from completely using the same posture for a long time, and the good experience of the user can be improved. In addition, when the desk is in the read-write mode at night, if a user humpback occurs, the lamp in the lampshade is turned off, and when the desk is in the read-write mode at day time, if the user humpback occurs, the small desk plate is turned over towards the direction far away from the user, so that when the user humpback occurs, the normal use of the user can be accurately interfered with low energy consumption, and the myopia and humpback prevention function can be smoothly realized.
In order to realize the study and entertainment of the chair, the chair is designed into a rocking chair, fig. 3 is a right side view of another embodiment of the chair for preventing myopia and humpback of the invention in an initial state, and the difference from the embodiment shown in fig. 2 is that the chair body is the rocking chair body 1, the bottom end of the arc-shaped rocking part 14 of the rocking chair body 1 is provided with a first groove 15, when the rocking chair body 1 is vertically arranged, the first groove 15 corresponds to the ground and is provided with a fourth electric telescopic rod 16, when the fourth electric telescopic rod 16 is contracted, no matter what kind of rocking state the rocking chair body 1 is in, the first groove 15 can accommodate the fourth electric telescopic rod 16 and the bottom of the fourth electric telescopic rod is not contacted with the fourth electric telescopic rod 16, the rocking chair body 1 is also provided with an angle sensor 17, and the chair surface is provided with a second pressure sensor 18, the controller switches between leaning and swinging states according to the pressure information detected by the first pressure sensor array 13 and the second pressure sensor 18 and the angle information detected by the angle sensor 17; and after the desk enters the leaning state, the controller determines the height of the user and the sitting position of the user according to the pressure information detected by the first pressure sensor array 13, controls the first motor 3, the second motor 4, the first electric telescopic rod 5 and the second electric telescopic rod 6 according to the height of the user and the sitting position of the user so as to adjust the relative position between the desk board 7 and the user, and controls the third motor 9, the third electric telescopic rod 10 and the fourth motor 11 so as to adjust the direction of the light source output by the lampshade 12 to be incident to the desk board 7.
In the embodiment, when only the second pressure sensor 18 of the first pressure sensor array 13 and the second pressure sensor 18 detects pressure information (after the second pressure sensor 18 detects pressure, if the first pressure sensor array 13 does not detect pressure within a corresponding preset time, it is determined that only the second pressure sensor 18 detects pressure), the controller controls the fourth electric telescopic rod 16 to contract, so as to enter the rocking state. When using, if the user wants to use the function of swaing of chair, only need sit the seat earlier on, wait for the shrink of fourth electric telescopic handle 16, because rocking chair body 1 has the arc to wave portion 14, after the shrink of fourth electric telescopic handle 16, rocking chair body 1 will have the trend of rocking, and the user can obviously perceive, and after the user perceived rocking chair body 1 has the trend of rocking, alright lie down and relax on the back of the chair.
After the control is switched to the swing state, the controller judges whether angle information detected by the angle sensor 17 is received, if so, only the second pressure sensor 18 in the first pressure sensor array 13 and the second pressure sensor 18 detects pressure information, and the fourth electric telescopic rod 16 is controlled to extend to abut against the first groove 15, so that the swing state is switched to the leaning state. Because the chair is triggered to enter the swing state based on the fact that only the second pressure sensor 18 detects the pressure information, if the chair directly judges whether only the second pressure sensor 18 detects the pressure information after entering the swing state, a user may not react to execute the swing operation, so that the state switching error rate is high, and the good experience of the user is low. Therefore, before the chair is switched from the swing state to the leaning state, the angle sensor 17 is adopted to detect whether the user perceives that the chair enters the swing state or not, and after the user perceives that the chair enters the swing state and executes the swing operation, the leaning state is switched, so that the switching accuracy can be improved, and the good experience of the user can be improved. When the chair is used, after a user performs a swinging operation, if the user wants to switch the chair to a leaning state, the user only needs to make the back part leave the chair back and sit on the chair seat, and then the chair can be switched from the swinging state to the leaning state. In addition, when the user uses the swing function of the chair, there may be a situation that the back of the user leaves the chair back to take a nearby object, so the controller is further configured to determine whether the duration of the pressure information not detected by the first pressure sensor array 13 is longer than a first preset time before controlling the electric telescopic rod 16 to extend, and if so, the electric telescopic rod 16 is controlled to extend, thereby the accuracy of switching and the good experience of the user can be further improved.
The controller is configured to stop the operation when the first pressure sensor array 13 and the second pressure sensor array 18 both detect pressure information, and enter a leaning state, where the fourth electric telescopic rod 16 is in an extended state, and abuts against the first groove 15. In the initial state, the fourth electric telescopic rod 16 is in the extended state, and if a user wants to use the leaning function of the chair, the user can sit on the seat and directly lean the back on the chair back.
After the controller switches the control to the leaning state, if only the second pressure sensor 18 of the first pressure sensor array 13 and the second pressure sensor 18 detects pressure information, it is determined whether the duration is longer than a second preset time, and if so, the fourth electric telescopic rod 16 is controlled to contract, so that the leaning state is switched to the swinging state. When the chair is used, a user only needs to leave the back of the chair to wait for a moment when the user wants to switch the chair from a leaning state to a swinging state, and the operation is very simple.
When the controller does not detect a pressure signal, the first pressure sensor array 13 and the second pressure sensor array 18 judge whether the duration is longer than a third preset time, if so, the controller controls the chair to enter an initial state, and controls the fourth electric telescopic rod 16 to extend to abut against the first groove 15. Because the user may leave the chair for a short time to take articles or completely leave the chair, the invention counts the time of the user leaving the chair before controlling the chair to enter the initial state, controls the chair to enter the initial state when the time of the user leaving exceeds a third preset time, and the chair is still kept in the state switched by the user when the time of the user leaving does not exceed the third preset time, thereby further improving the use quality of the user. The embodiment shows that the automatic switching device can realize the automatic switching of the leaning and swinging functions, and has the advantages of rich functions and wider application range.
