Technical Field
[0001] The invention relates to the technical field of glass lifters, and in particular to an automobile glass lifter. Background Art
[0002] Common car window glass includes single-layer glass and double-layer glass. Single-layer glass has a simpler structure and a lower cost, while double-layer glass has a more complex structure and is more expensive, but has better sound insulation and heat insulation effects.
[0003] At present, double-layer glass is often used in cars with higher prices as an important configuration to improve vehicle comfort. However, compared with single-layer glass, double-layer glass also has the problem of poor transparency and light transmittance. In particular, double-layer glass windows with film have a greater obstruction to the line of sight in driving environments such as at night, which not only causes inconvenience to the driver, but also poses certain safety hazards.

[0034] The following embodiments of the technical solution of the present invention are described in detail in conjunction with the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the present invention, and are therefore only used as examples, and cannot be used to limit the protection scope of the present invention.
[0035] See also Figures 1 to 3 The present invention provides an automobile glass lifter, comprising a guide rail 10, a driving assembly 20 and a glass clamping assembly 30. After the required glass is clamped by the glass clamping assembly 30, the driving assembly 20 lifts the glass through the guide rail 10.
[0036] Specifically, the guide rail 10 is fixedly arranged in the vehicle door, and two guide rails 10 are symmetrically arranged, and fixed pulleys 11 are arranged at the upper and lower ends of the guide rails 10. The driving assembly 20 includes a motor 21 and a rope 22. The motor 21 is fixedly arranged in the vehicle door. The rope 22 is connected end to end in an ∞ shape, and the two ends are respectively sleeved on the two pulleys of the two guide rails 10. The motor 21 can drive the rope 22 to move. The glass clamping assembly 30 includes a slider 31 and a converter 32. The two sliders 31 are respectively slidably connected to the two guide rails 10 and are both connected to the rope 22. The slider 31 is provided with a clamp 33 that can clamp two glasses respectively. The converter 32 is arranged on the slider 31 and can drive the clamp 33 to open and close.
[0037] Before raising or lowering the glass, first drive the clamp 33 to open and close to clamp the glass through the converter 32. There are two glasses in the door, namely single-layer glass and double-layer glass. The two clamps 33 can clamp these two glasses respectively. Different glasses can be selected according to the actual scene when using. For example, when it rains at night, the double-layer glass affects the field of vision due to its poor light transmittance. If the window is opened, rain will drift into the car. At this time, single-layer glass can be selected as the window glass. After selecting one of the glasses to clamp and fix, the motor 21 drives the rope 22 to move, and the rope 22 drives the sliders 31 on both sides to move upward to lift the glass. By setting two types of glass, it can provide better heat insulation and sound insulation through double-layer glass to improve comfort, and can also provide a clearer field of vision through single-layer glass to improve driving safety.
[0038] Specifically, the drive assembly 20 includes a wire rope drum 23, a worm wheel 24 and a worm 25. The wire rope drum 23 is fixedly sleeved on the rope 22, and a spiral wire rope is provided on the surface along the axial direction. The worm wheel 24 and the worm 25 cooperate, and the worm wheel 24 is rotatably arranged, and the back side in the figure is provided with a shifting tooth that can shift the spiral wire rope. The motor 21 is connected to the worm 25 and can drive it to rotate. The motor 21 drives the worm 25 to rotate, which drives the worm wheel 24 to rotate, and the wire rope drum 23 can be shifted to move, so as to drive the rope 22 to move, and the slider 31 can be driven to move on the guide rail 10, so as to raise and lower the glass. In addition, the worm wheel 24 cannot reversely drive the worm 25, so the lifting and lowering of the window glass can only be driven by the motor 21, and the glass cannot be pressed or raised manually, which improves safety.
[0039] Specifically, the clamp 33 includes a fixed block 331 and a clamp block 332. The fixed block 331 is fixedly set on the slider 31, and movable clamp blocks 332 are provided on both sides. By driving the clamp block 332 to move toward the fixed block 331, the clamp block 332 and the fixed block 331 can clamp the glass together, and both clamp blocks can clamp the glass with the fixed block, thereby clamping two types of glass respectively.
[0040] The converter 32 includes a knob, which is rotatably arranged on the slider 31, and two push rods 323 are arranged on the outer wall, and the two push rods 323 can respectively push two clamping blocks 332. By rotating the knob, one of the push rods 323 is driven to move circumferentially, and the clamping block 332 can be pushed to move toward the fixed block 331, so that the clamping block and the fixed block clamp the glass together.
[0041] In this embodiment, a T-shaped slide groove 311 is provided on the slider 31, and the clamping block 332 is slidably connected to the slide groove 311, which is used to limit the stroke of the clamping block, so that the clamping block 332 can only make a linear reciprocating movement relative to the fixed block 331. A strip groove 333 is provided on the clamping block 332, and a cylindrical protrusion 324 slidably connected to the slide groove 311 is provided on the push rod 323. When the push rod 323 rotates, the clamping block 332 can be driven to move through the protrusion 324, and the protrusion 324 moves in the slide groove 311 at the same time. Under the limit of the slide groove, the clamping block can be close to or away from the fixed block.
[0042] Specifically, the knob includes an upper knob 321 and a lower knob 322, the upper knob 321 is rotatably arranged on the lower knob 322, the lower knob 322 is rotatably arranged on the slider 31, and two push rods 323 are respectively arranged on the outer walls of the upper knob 321 and the lower knob 322. In addition, the slider 31 and the lower knob 322 are both provided with a motor 325, and the upper knob 321, the lower knob 322 and the slider 31 are sequentially rotatably connected by the motor 325. By setting the knobs of the upper and lower layer structures, the effect of the two push rods 323 moving independently can be achieved, so that the clamping block 332 can be pushed to clamp the glass at the same time, so as to achieve the effect of clamping and lifting the two glasses together. When in use, the driver can choose to lift the single-layer glass or the double-layer glass, or can lift the two glasses together to achieve better sound insulation and heat insulation effects.
[0043] The working principle of the above-mentioned automobile glass lifter is as follows: firstly, the required glass is selected, and the two motors 325 drive the upper knob 321 and the lower knob 322 to rotate, and the push rod 323 pushes the corresponding clamping block 332 to move toward the fixing block 331 to clamp and fix the corresponding glass. Then, the motor 21 is started, the worm 25 is driven to drive the worm wheel 24 to rotate, and the worm wheel 24 drives the wire rope to move, thereby driving the rope 22 to move, and the slider 31 is displaced on the guide rail 10 to lift the clamped glass.
[0044] The above-mentioned automobile window lifter can clamp both single-layer glass and double-layer glass window glasses according to different usage scenarios. For example, double-layer glass can provide better heat insulation and sound insulation, improving comfort, and single-layer glass can provide a clearer field of view and improve driving safety. The two glasses can also be raised at the same time to achieve better sound insulation and heat insulation effects.
