Abstract
Description
Technical Field
[0001] This utility model relates to the field of glass lifter technology, and in particular to a stable double-arm glass lifter. Background Technology
[0002] Window regulators are the devices used to raise and lower car door windows, and are mainly divided into two categories: electric window regulators and manual window regulators. Nowadays, many car door windows are generally equipped with push-button electric window regulators.
[0003] For example, the authorization notice number "CN207647354U" describes a type of electric rear door window regulator for automobiles. Although this double-arm window regulator, with its two lifting arms, can ensure parallel lifting and lowering of the glass compared to a single-arm regulator, and has a larger lifting force, ensuring smooth glass operation, the auxiliary arm and auxiliary guide rail are slidably connected. The glass is only fixed in place by the main arm, which is not secure enough. Furthermore, after the glass reaches the top, the main arm is fixed via gears and a rotating head, which can lead to situations where the window cannot close completely. Utility Model Content
[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a stable double-arm glass lifter.
[0005] To achieve the above objectives, the present invention adopts the following technical solution:
[0006] Design a stable double-arm window regulator, including a door frame and a motor reducer. The door frame has a mounting block on its surface. The output end of the motor reducer has a rotating shaft, which is rotatably connected to the mounting block. The rotating shaft has two threaded sections with opposite directions of rotation. Each of the two threaded sections is threadedly connected to a first slider. Each of the two first sliders is hinged to a support arm. The two support arms are hinged together at the middle. Each of the two support arms has a second slider at its upper end. Each of the two second sliders has a support block at its upper end. The upper ends of the two support blocks are slidably connected to a first track. The two ends of the first track are slidably connected to the door frame. A glass clamp is provided above the first track. A buffer assembly is provided between the first track and the glass clamp.
[0007] Preferably, the buffer assembly includes two slide rods, both of which are disposed on the lower surface of the glass clamp. The lower ends of both slide rods slide through the first track and are provided with end blocks. Springs are sleeved on the outside of both slide rods. The upper ends of the springs are connected to the lower surface of the first track, and the lower ends of the springs are connected to the upper surface of the end blocks.
[0008] Preferably, the lower surface of the first track is provided with a first T-shaped groove, and two first limiting blocks are provided inside the first T-shaped groove. The lower surfaces of the two first limiting blocks are connected to the upper ends of the support blocks one by one.
[0009] Preferably, each of the two first sliders has a first connecting block on its upper surface, and each of the two support arms has a second connecting block at its lower end. The two first connecting blocks and the two second connecting blocks correspond one-to-one, and the first connecting blocks and the second connecting blocks are hinged together by a pin.
[0010] Preferably, a second track is provided below the two first sliders, and the first sliders are slidably connected to the second track.
[0011] Preferably, the upper surface of the second track is provided with a second T-shaped groove, and two second limiting blocks are provided inside the second T-shaped groove. The upper surface of each of the two second limiting blocks is provided with a third connecting block. The two third connecting blocks correspond one-to-one with the two first sliders, and the upper end of the third connecting block is connected to the lower surface of the first slider.
[0012] The present invention proposes a stable double-arm window regulator with the following advantages: Because the rotating shaft has two sections with opposite spiral directions, the two first sliders can be brought together or dispersed by starting the motor and reducer. Through the two support arms, the first track can be raised or lowered, and the glass is fixed in place by the two support arms, ensuring a very secure fixation. Simultaneously, the buffer component, when the glass installed on the glass clamp reaches the top, will squeeze the glass clamp, causing the slide rod to move downwards, thereby stretching the spring. Due to the stretching effect of the spring, the glass installed on the glass clamp is firmly pressed against the upper edge of the window, preventing any situation where it cannot be closed tightly.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0019] Reference Figure 1-4 A stable double-arm window regulator includes a door frame and a motor reducer 1. The door frame surface has mounting blocks 2. The output end of the motor reducer 1 has a rotating shaft 3, which is rotatably connected to the mounting blocks 2, making the rotation of the shaft 3 smoother. The rotating shaft 3 has two threaded sections with opposite directions of rotation, each threadedly connected to a first slider 4. Rotation of the rotating shaft 3 allows the two first sliders 4 to converge or separate. Each first slider 4 is hinged to a support arm 5, which is hinged at the middle. Each support arm 5 has a second slider 6 at its upper end, and each second slider 6 has a support block 7 hinged at its upper end. The upper ends of the two support blocks 7 are slidably connected to a first track 8, which is slidably connected to the door frame at both ends, ensuring that the first track 8 can only rise or fall. A glass clamp 9 is located above the first track 8, and a buffer assembly is located between the first track 8 and the glass clamp 9.
[0020] The buffer assembly includes two slide rods 10, both of which are mounted on the lower surface of the glass clamp 9. The lower ends of both slide rods 10 slide through the first track 8 and are equipped with end blocks 11. Springs 12 are sleeved on the outside of each slide rod 10. The upper end of the spring 12 is connected to the lower surface of the first track 8, and the lower end of the spring 12 is connected to the upper surface of the end block 11. When the glass installed on the glass clamp 9 reaches the top, it will compress the glass clamp 9, causing the slide rods 10 to move downwards, thereby stretching the springs 12. Due to the stretching effect of the springs 12, the glass installed on the glass clamp 9 is firmly pressed against the upper edge of the car window, preventing any situation where the window cannot be closed tightly.
[0021] The lower surface of the first track 8 is provided with a first T-shaped groove 13, and the inside of the first T-shaped groove 13 is provided with two first limiting blocks 14, and the lower surfaces of the two first limiting blocks 14 are connected to the upper end of the support block 7 in a one-to-one correspondence.
[0022] The upper surfaces of the two first sliders 4 are provided with first connecting blocks 15, and the lower ends of the two support arms 5 are provided with second connecting blocks 16. The two first connecting blocks 15 and the two second connecting blocks 16 correspond one-to-one, and the first connecting blocks 15 and the second connecting blocks 16 are hinged by insert shafts 17.
[0023] A second track 18 is provided below the two first sliders 4, and the first sliders 4 are slidably connected to the second track 18. With the help of the second track 18, the two first sliders 4 are more stable when moving in a straight line.
[0024] The upper surface of the second track 18 is provided with a second T-shaped groove 19. The second T-shaped groove 19 is provided with two second limiting blocks 20. The upper surface of each of the two second limiting blocks 20 is provided with a third connecting block 21. The two third connecting blocks 21 correspond one-to-one with the two first sliders 4. The upper end of the third connecting block 21 is connected to the lower surface of the first slider 4.
[0025] Working principle: Since the rotating shaft 3 has two threaded sections with opposite directions of rotation, the two first sliders 4 can be brought together or dispersed by starting the motor reducer 1. Since the two threaded sections are threadedly connected to the first sliders 4 and the two first sliders 4 are hinged to the support arms 5, the lower ends of the two support arms 5 can be brought together or dispersed. Since the upper ends of the two second sliders 6 are hinged to the support blocks 7 and the upper ends of the two support blocks 7 are slidably connected to the first track 8, the first track 8 can be raised or lowered by the two support arms 5. The glass is fixed in place by the two support arms 5, and the fixation is very reliable.
[0026] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
