Further optionally, the motor assembly comprises: the device comprises a motor, a Hall sensor arranged on the motor and an electromagnetic brake arranged on the motor, wherein the Hall sensor and the electromagnetic brake are respectively connected with a controller;

the Hall sensor is used for monitoring the number of turns of the motor;

and the controller is also used for acquiring the position point of the lifting chair 1 and/or controlling the electromagnetic brake according to the number of rotating circles of the motor monitored by the Hall sensor.

Specifically, when the number of rotations of the motor monitored by the hall sensor is greater than or equal to a rotation threshold (a person skilled in the art can determine the rotation threshold according to years of experience and engineering requirements), the controller controls the motor to stop running and/or controls the electromagnetic brake to cut off power supply.

In some embodiments, the controller further comprises a calculation module for calculating the running distance of the lifting chair 1 according to the number of turns of the motor rotation monitored by the hall sensor, and transmitting the running distance of the lifting chair 1 to the controller; and the controller is also used for determining the position point of the lifting chair 1 on the track 2 according to the running distance of the lifting chair 1.

It should be noted that, in the embodiment of the present invention, the manner of calculating the running distance of the lifting chair 1 by the calculation module according to the number of rotations of the motor monitored by the hall sensor is well known to those skilled in the art, and those skilled in the art may select different calculation manners according to engineering requirements, so that the specific implementation manner thereof is not described too much.

In some embodiments, referring to fig. 6, the armrests 4 are disposed on two sides of the seat 3, and the display screen 13 is disposed on the armrest 4 on one side for displaying the position point, the operation state and the diagnosis information of the lifting chair 1;

a direction toggle piece 12 is arranged on the armrest 4 at the other side of the seat 3 and is used for changing the running direction of the lifting chair 1;

the display 13 and the direction toggle piece 12 can be connected with the controller by wires (the connection mode of the display 13 and the direction toggle piece 12 with the controller can be selected according to engineering requirements).

In some embodiments, the type of display 13 may be, but is not limited to, an LCD display; the direction toggle piece 12 is implemented by a sensor, and particularly, but not limited to, the running direction of the lift chair 1 can be changed by pressing each direction switch in the direction toggle piece 12.

It should be noted that the operation state of the lift chair 1 may include, but is not limited to: the lifting chair 1 stops running and the lifting chair 1 starts running; diagnostic information may include, but is not limited to: lost reference times, seat 3 rotation limit angle, obstacle in front, obstacle on side, battery level, low voltage times, brake failure, main relay failure on the controller, and use times of the lift chair 1.

For example, assuming that the type of the display screen 13 on the armrest 4 of the stair chair of model a is an LCD display screen, when the motor of the stair chair of model a rotates, the hall sensor monitors the number of revolutions of the motor, the calculation module in the controller of the stair chair of model a calculates the travel distance of the chair 1 according to the number of revolutions of the motor monitored by the hall sensor, the controller determines the position point of the chair 1 on the rail 2 according to the travel distance of the chair 1 and marks a corresponding position point (0-99999) on the distance, and the controller transmits the position point of the chair 1 at the moment to the LCD display screen on the armrest 4 on one side of the chair 1 for display.

For another example, referring to fig. 7, assuming that the controller of the B-model stairlift chair is implemented by a PCB, when speed setting is to be performed on the installed track 2, the controller needs to press the SW2 menu key on the PCB controller for 5 seconds from the starting point O of the track 2 (i.e. the lowest starting point of the stairlift) to enter the speed setting state, the B-model stairlift chair runs upwards, the speed is set to be fast (fast is represented by H) according to the straight section of the track 2, when the starting point of the turning section is reached, the controller needs to press the SW1 selection key on the PCB controller to select to be slow (slow is represented by L), and the controller needs to press the SW2 menu key on the PCB controller for 5 seconds to exit the speed setting state; the downward running speed of the B-type stair lift chair is automatically set to be 70% of the upward running speed (namely 70% of the upward fast speed section and 70% of the upward slow speed section) through the PCB controller;

assuming that the operation speed of the type B stair chair has been set, and when the downward operation speed of the type B stair chair unexpectedly runs out of control and exceeds 1.5 times of the set operation speed (it should be noted that a person skilled in the art can set "how many times the set operation speed is exceeded" herein according to actual needs or work experience), the PCB controller monitors the data of the rotating speed (the "rotating speed" in this embodiment refers to the number of revolutions per minute of the motor) through the hall sensor, and then automatically enters the overspeed protection function program, and in combination with the normally closed switch at the overspeed protection mechanism on the gear driving mechanism 10 of the lower track 2, after being forcibly disconnected by the mechanical device, the PCB controller monitors the disconnection signal, and immediately and automatically controls the motor to stop running, and the PCB controller starts the missing reference protection function, and before there is no calibration reference position, all the speeds of any position upwards or downwards automatically change into slow speeds; meanwhile, the PCB controller disconnects the power supply of an electromagnetic brake arranged on the motor, so that the motor is braked to be dead when the brake is powered off; as long as any one of the protection functions (it should be noted that, the protection function here refers to the loss reference protection function and the electromagnetic power-off protection function) is started, the stair lift chair can be prevented from running out of control continuously, and the PCB controller temporarily shields the previously set running speed scheme; after a normally closed switch at the overspeed protection mechanical device is recovered, the stair lift chair is only stopped to the starting point position again for charging, when the PCB controller detects that the stair lift chair is charged at the starting point, the lost reference protection function mode is immediately exited, and then all functions are automatically recovered and automatically adjusted to the previously adjusted speed scheme; thus, danger is prevented from occurring, and the personal safety of a user is guaranteed.

Further optionally, the main cabinet 7 further includes: the temperature control element is arranged at the MOS tube in the mainframe box 7 and is used for monitoring the voltage value of the MOS tube; the temperature control element is arranged on the controller;

It will be readily appreciated that when the controller is implemented by a PCB, the temperature controlled element may be, but is not limited to being, soldered directly to the PCB.

Specifically, when the voltage value of the MOS tube monitored by the temperature control element is greater than or equal to the voltage threshold value, the controller controls the lifting chair 1 to stop running;

when the voltage value of the MOS tube monitored by the temperature control element is smaller than the voltage threshold value, the controller controls the lifting chair 1 to normally operate.

It is easily understood that the controller controlling the elevating chair 1 to stop running means that the controller controls the motor in the main cabinet 7 to stop running.

In some embodiments, a MOS transistor in the main chassis 7 may be used to control the operation of the motor; the voltage threshold may be set to 4.3V, but is not limited thereto, and may be set by those skilled in the art according to work experience or engineering requirements.

For example, when a user uses the stair lift chair, the user may use the stair lift chair for a long time without interruption, or the user may exceed the rated load weight that the stair lift chair can bear, which may cause the temperature of the MOS transistor connected to the controller for controlling the operation of the motor to be too high, which may cause the burning and the fire, and the temperature of the motor may be too high and may be burned out; in order to protect the controller and the motor to be normally used, a high-precision temperature control element R31(CMF0805-912 □ 3550B) is arranged at a high-power MOS tube Q3, Q26(STB75NF20) which is arranged on the controller of the C-type stair lift chair and used for controlling the motor to run, the temperature control element detects the temperature change of the high-power MOS transistors Q3 and Q26(STB75NF20), the temperature control element transmits the voltage value change to the controller, and once the temperature is overhigh, the converted voltage reaches 4.3V or above, the controller automatically controls the motor to stop running immediately, the C-type stair lift chair can be reused only after the temperature of high-power MOS transistors Q3 and Q26(STB75NF20) for controlling the motor to run drops, the controller and the motor are protected, and the danger of a user in the using process is avoided, so that the personal safety of the user is guaranteed.

In some embodiments, a safety belt is further provided on the seat 3 for protecting the user. The female head of the safety belt is connected with the controller, and the direction poking piece 12 on the armrest 4 can control the lifting chair 1 to move upwards or downwards only after the controller receives a signal that the bolt of the male head of the safety belt is inserted into the female head of the safety belt when the bolt of the male head of the safety belt is inserted into the female head of the safety belt; if the bolt of the male head of the safety belt is not inserted into the female head of the safety belt, the controller cannot receive a signal that the bolt of the male head of the safety belt is inserted into the female head of the safety belt, and the lifting chair 1 cannot move upwards or downwards along the track 2; thereby ensuring the safety of the user.

According to the stair lifting chair provided by the embodiment, the danger caused by the fact that the angle between the seat 3 and the main case 7 forms a limit angle due to improper operation of a user can be avoided by utilizing the manual rotating device, and therefore personal safety of the user is guaranteed; by arranging the travel switches at each edge of the main case 7, danger caused by obstacles in front of or on the side of the running direction can be avoided, and the function of protecting users is achieved; by arranging the Hall sensor and the electromagnetic brake on the motor, the motor can be controlled to stop running immediately and the electromagnetic brake can be controlled to stop running when the controller monitors that the lifting chair 1 runs at an overspeed through the Hall sensor, so that danger is prevented from occurring and personal safety of a user is guaranteed; the temperature control element is arranged at the MOS tube in the main case 7, so that the phenomenon that the MOS tube is burnt to cause fire or the motor is burnt out due to overhigh temperature can be avoided, the safe operation of the stair lift chair is ensured, and the personal safety of a user is ensured;
