[0020] This section will describe in detail the specific embodiments of the utility model. The preferred embodiments of the utility model are shown in the accompanying drawings. The purpose of the accompanying drawings is to supplement the description of the text part of the specification with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the utility model, but it cannot be understood as a limitation on the protection scope of the utility model.
[0021] Reference Figure 1-3 The utility model discloses a window glass lifter capable of reducing abnormal noise, comprising a window glass 1, a first bearing 5 is provided below the window glass 1, guide grooves 2 are provided at upper and lower symmetrical positions of the first bearing 5, inner grooves 12 are provided at symmetrical positions inside the guide grooves 2, and a plurality of steel balls 13 are provided inside the four inner grooves 12.
[0022] The inner ring of the first bearing 5 is fixedly connected with three driven movable rods 4 and an active movable rod 6. The other ends of the three driven movable rods 4 are fixedly connected with guide blocks 3. The three guide blocks 3 include a slider 14 and a second bearing 15. By providing an inner groove 12 and a steel ball 13, the contact area between the slider 14 and the inside of the guide groove 2 is reduced by the steel ball 13, so that the friction between the slider 14 and the inside of the guide groove 2 is reduced, thereby greatly reducing the noise generated by the friction between the slider 14 and the inside of the guide groove 2.
[0023] The other end of the active movable rod 6 is fixedly connected to a sector rack 7, the teeth of the sector rack 7 are meshedly connected to a gear 8, the rotating shaft of the gear 8 is fixedly connected to a worm gear structure 9, the teeth of the worm gear structure 9 are meshedly connected to a worm structure 10, one end of the worm structure 10 is fixedly connected to a motor 11, the upper guide groove 2 is fixedly connected to the lower end of the vehicle window glass 1, the surfaces of the two upper sliders 14 are slidably connected to the guide groove 2, the surface of the lower slider 14 is slidably connected to the guide groove 2, and the upper ends of the three sliders 14 are fixedly connected to the second bearing 15.
