Abstract
The utility model discloses a car window glass lifting mechanism on a car. Car window glass is fixedly connected to one surface of a fixing plate, a nut and two roller sliders are fixed onto the other surface of the fixing plate, the two roller sliders are arranged on two sides of the fixing plate, and the nut is arranged between the two roller sliders. Two circular guiding rods respectively penetrate through middle cavities of the two roller sliders, and a roller in the inner cavity of each roller slider contacts with the outer wall of the respective circular guiding rod. A screw rod penetrating through the nut and the upper ends of the two circular guiding rods are jointly connected with an upper support plate, and the screw rod and the lower ends of the circular guiding rods are jointly connected with a lower support plate. A centripetal rolling bearing is arranged between the screw rod and the upper support plate, a thrust rolling bearing is arranged between the screw rod and the lower support plate, the lower end of the screw rod downwardly extends out of the lower support plate, and the screw rod is connected with an output shaft of a motor. The car window glass lifting mechanism adopting the spirally rolling sliders has the advantages of reliable work of the mechanism, simple structure, fine force bearing condition of parts and difficult damage.
Description
Technical field
The utility model relates to a kind of lifting mechanism for vehicle window glass, refers in particular to the lifting mechanism for vehicle window glass that is used on the car, belongs to traffic and transport field.
Background technology
The existing lifting mechanism for vehicle window glass of China is divided into two big classes, and a class is a rope traction mechanism, and another kind of is linkage.There is the wire rope easy fracture in rope traction mechanism, the flimsy shortcoming of race plastic gasket of wire rope leading block, reason is at rope traction fixedly in the slide block lifting process of glass for vehicle window, haulage cable and slide block guide rail produce sliding friction, and be big to the wearing and tearing of wire rope, and the diameter of leading block is less, flexural stress when wire rope passes through leading block is bigger, that have even do not have leading block, directly crooked at the guide rail two ends, the flexural stress that wire rope is subjected to is bigger.The long-term lifting of glass for vehicle window, haulage cable bending and un and wearing and tearing, tired fracture of wire is bound to, broken until integral body, the race plastic gasket of wire rope leading block, though less to the wearing and tearing of wire rope generation, plastic gasket intensity is low, easily damage by pressure, often need more change steel rope and change steel rope leading block.And linkage pressure angle in car glass lifting process alters a great deal, and when glass for vehicle window rose to the higher position, parallel index cam mechanism was very big, makes the transmission force property of mechanism and stationary performance all relatively poor.
Summary of the invention
The purpose of this utility model is for overcoming the deficiencies in the prior art, provides that a kind of stationarity is good, reliable operation and non-damageable lifting mechanism for vehicle window glass.
The technical solution adopted in the utility model is: glass for vehicle window is fixedly connected on the fixed head one side, and the fixed head another side is fixed with a nut and two ball slide blocks, and two ball slide blocks are arranged at the fixed head both sides, and nut is arranged in the middle of two ball slide blocks; Two circular guide rods pass two ball slide block lumens respectively, and the ball in the ball slide block inner chamber contacts with circular guide rod outer wall; Pass a screw rod of nut and the upper end of two circular guide rods and be connected with a upper bearing plate jointly, the lower end of screw rod and two circular guide rods is connected with lower supporting plate jointly; Be provided with radial antifriction bearing between screw rod and the upper bearing plate, be provided with thrust bearing between screw rod and the lower supporting plate, the lower ends downward of screw rod is stretched out lower supporting plate and is connected the output shaft of motor.
The utility model adopts spiral ball slide block lifting mechanism for vehicle window glass, better than existing linkage stationarity, than existing wire rope mechanism reliable operation, the part stress situation is good, not fragile, and saved worm and gear required in linkage and the wire rope mechanism or rack-and-pinion reducing gear, simple in structure, cost reduces.
Description of drawings
Fig. 1 is the utility model three-dimensional structure diagram.
Among the figure: 1. screw rod; 2. nut; 3. circular guide rod; 4. ball slide block; 5. glass fixed head; 6. radial antifriction bearing; 7. thrust bearing; 8. upper bearing plate; 9. lower supporting plate; 10. threaded connector; 11. motor; 12. shaft coupling; 13.U type supporting plate.
The specific embodiment
As Fig. 1, glass for vehicle window is fixedly connected on fixed head 5 one sides, and fixedly connected nut 2 and ball slide block 4 on the another side of fixed head 5 have two ball slide blocks 4 to be fixed on the two sides of fixed head 5 another sides, at the center fixed nut 2 of two ball slide blocks 4.Ball slide block 4 is commercial product, and its inner chamber has equally distributed spherical ball, and two circular guide rods 3 pass two ball slide block 4 lumens respectively, and the spherical ball in ball slide block 4 inner chambers is contacted with the outer wall of circular guide rod 3.A screw rod 1 passes nut 2, and the upper end of screw rod 1 and two circular guide rods 3 is connected a upper bearing plate 8 jointly, and the lower end of screw rod 1 and two circular guide rods 3 is connected lower supporting plate 9 jointly.A radial antifriction bearing 6 is installed between screw rod 1 and the upper bearing plate 8, a thrust bearing 7 is installed between screw rod 1 and the lower supporting plate 9, and the lower ends downward of screw rod 1 is stretched out lower supporting plate 9.
Motor 11 is vertically set on the bottom of screw rod 1, and a U type supporting plate 13 is set in the positive bottom of motor 11, and U type supporting plate 13 is contacted with motor 11, U type supporting plate 13 is fixedly connected on the lower supporting plate 9 by threaded connector 10, thereby makes motor 11 stable.The output shaft of motor 11 drives screw rod 1 rotation by extending area, shaft coupling 12 connecting screw rods, 1 lower end.
Operating principle of the present utility model is: drive screw rod 1 positive and negative rotation by motor 11, nut 2 is moved up and down along screw rod 1, because the support of circular guide rod 11 makes nut 2 can not produce deflection in moving process, guaranteed the stressed good of nut 2.Nut 2 drives ball slide block 4 inside when moving up and down ball moves along circular guide peg 3 rollings, and ball slide block 4 is rolling friction along the mobile friction of circular guide rod 3, and resistance is very little.Simultaneously, screw rod 1 adopts rolling bearing to connect with the revolute pair of upper and lower base plate 8,9, makes the rotary resistance of revolute pair less, thereby realizes the elevating movement of glass for vehicle window.
The pitch size of screw rod 1 of the present utility model and nut 2 is calculated according to existing glass for vehicle window lifting velocity and is determined, if need the vehicle window lifting velocity faster, can increase pitch.
