Description

Electric control chair

The utility model relates to the seat of a kind of seat, particularly a kind of electronic regulation and control.

Conventional seat, no matter be movably common seat, or fixed seat on the vehicle, the general angle that all can not regulate the height and the backrest at its seat by individual's wish, changeless modeling structure allows the people sit for a long time and feels tired easily.The seat that can regulate seat height and backrest angle is now also arranged, but all by the user with the rotation mode manual regulation, the auto use chair of many either sitting or lying on it is proposed in recent years, as the automobile-used either sitting or lying on it chair that CN2177629Y proposes, its backrest angle can transfer to seat cushion and maintain an equal level, but its adjusting still is manual control, make the old man children still feel operation inconvenience, if can be with automatic replacement manual regulation, will be to the user, particularly the weakling brings great convenience and practicality.

The purpose of this utility model provides and a kind ofly can realize self-regulating Electric control chair by button operation, can adjust the suitable fit seat that is fit to various builds, front and back position that can the automatic compensation seat, the seat of appropriateness, the appropriate benefit of backrest angle highly up and down.

The design plan that the utility model adopted is: Electric control chair, it comprises cushion, the chair back, headrest and bracing frame, architectural feature also has by the input button, cpu controller, the miniature motor that links to each other with controller output end, the gear that links to each other with the micromotor mouth and retarder are formed and are regulated seat front and back position, the motorized adjustment controller of height and backrest angle up and down.

The advantage of said structure is, as long as the user is an input button of pressing controller gently, just scalable goes out to be fit to the best seat of different builds, comfortable fit, appropriate benefit, has overcome many troubles of regulating by muscle power, particularly gives old, children and the many convenience of weakling.This kind structure can be widely used in car and boat seat, meeting and office with chair etc.The special-purpose chair of vehicle particularly can be at any time according to the time and the degree of fatigue of driving as the seat of chaufeur, adjusts the angle that reaches backrest before and after the seat, up and down, is transferred to the optimum position and tiredly keeps energetic to overcome.If make passenger seat, also can easily backrest be put to optional position less than 180 degree, make the bedding that respite is had a rest temporarily.A comfortable proper seat makes people's sitting not feel tired, and energy is vigorous for a long time, is the pure electromechanical integrated product of modernized breath.

The 26S Proteasome Structure and Function of embodiment is described below in conjunction with accompanying drawing.

The structure of Electric control chair comprises seat, power transmission and regulating control.Regulating control partly is the center of whole Electric control chair, as shown in Figure 1.It is actually the power controller of a tape input and output, available cpu chip or micro controller system, and concrete model requires to decide on controller function.Its input end is various input switch buttons, represents the parallel motion of seat respectively as button (6,7,8), and height is regulated, the angular adjustment of backrest etc.Micromotor M1, M2, M3, M4 are performance element, are parallel motion as M1, and M2, M3 are that height is regulated, and M4 is that backrest angle is regulated motor.

Seat comprises seat cushion, backrest and supports the bracing frame of seat cushion, bracing frame also is the framework of seat, be connected to the bracing frame of seat lifting or translation by two parallel strut bars (14) by supporting seat (11) and two parallel slide rails (13), referring to Fig. 2 and Fig. 3.

Because being with the seat of backrest is the very big seat tool of randomness, it will bear various different personality people's body weight and application force, that is to say because user's individual difference, seat will bear various dynamic application forces, consider these factors in the design, each movable parts has all adopted big moment design, and seat can be resetted by automatically regulating under free position, and seat all can be by the button motorized adjustment to optimum regime when people's seat is arranged.

Propulsion source is the electrical motor M1-M4 of big moment, and its mouth slows down with the increase moment by worm and gear, and utilizes the latching characteristics of worm and gear, and seat is stopped and lock-bit in free position under the control of instruction, and is safe in utilization to guarantee.

The various regulatory functions of adjusted and controlled description below in conjunction with seat.

The height adjustment of seat, referring to Fig. 2, it comprises height adjustment and guide controller, by micromotor M2, worm reduction box (12), connecting rod (10), crank (15), strut bar (14) and on connection folder (9) forms, the two ends of strut bar (14) fix by supporting seat (11) and the slide rail (13) that is parallel to each other.Establish on the strut bar some be connected with seat cushion be connected folder (9), set firmly the crank (15) that links to each other with connecting rod under the strut bar.The other end of connecting rod (10) links to each other with the output shaft of worm reduction box (12).Crank under another strut bar links to each other with the drop-gear box of another micromotor M3 output, does not retouch out micromotor M3 drop-gear box (12) and connecting rod (10) in Fig. 2.When needs are regulated the height of seat, (7) push button, sent instruction promptly for M2 and M3, motor M 2 and M3 work, the driven by motor worm screw is rotated, and the direction of arrow is represented the back-out or the screw-in of a core among the figure, rotatablely moving of motor is become the straight-line motion of connecting rod by worm and gear, swing by degree in crank angle will connect folder raises or reduces, thereby regulates the height of seat cushion.Fig. 4 is the embodiment in addition of height of seat adjustment structure, and motor output is directly linked to each other with seat cushion board by connecting rod (10) through worm reduction box (12) output by screw shaft (16), can carry out work by a motor with a big moment.

The regulating mechanism of parallel motion is by shown in Figure 3, and the horizontal adjustment controller of seat is made up of micromotor M1, worm shaft (16), worm reduction box (12), slide rail (13), setting nut (18) and adjusting screw(rod) (19).Micromotor M1 is connected with the worm reduction box (12) on both sides by worm shaft (16), and the adjusting worm screw (19) on the worm-wheel shaft (17) fixes by setting nut (18) and slide rail (13).The other end of adjusting screw(rod) (19) is supported on the permanent seat of substrate by supporting base (20).Represent advancing of guide rail or direction of retreat with the direction of arrow.Micromotor M1 starts by worm-wheel shaft (17) rotation in screw shaft (16) the drive worm reduction box when pushing button (6), also driving adjusting screw(rod) (19) rotates, setting nut (18) is moved, make the seat horizontal displacement thereby drive the slide rail displacement that fixes with setting nut.

The backrest angle regulating mechanism of seat as shown in Figure 5.It is made up of micromotor M4, transmission shaft (23), retarder (24) moving gear (25), fixed gear (26) and curved bar (27).Micromotor M1 is linked to each other with retarder by transmission shaft, by the engagement of moving gear and fixed gear, an end of curved bar and fixed gear axle fixedly the other end and seat cushion (28) one side fix.When 4 work of motor M when closing button (8), moving gear changes around the axle core of fixed gear, and making whole backrest is that rotate at the center with the curved bar, thereby realizes the angular adjustment of back of seat, transfer to 180 degree positions as if angle, back of seat is kept flat can be used as interim bedding use backrest and seat cushion.
