Description

Technical Field

[0001] This utility model belongs to the technical field of electric window regulators, specifically relating to a dual-track zero-step window regulator. Background Technology

[0002] To improve vehicle aesthetics and reduce wind resistance and noise between door glass and window frames, the zero-step difference design between door glass and window frames is becoming increasingly common in automobiles.

[0003] The zero-step difference structure between the door glass and the window frame consists of the door glass and a zero-step difference dual-track window regulator assembly. This assembly typically comprises a guide rail assembly, a drive assembly, a bracket assembly, and a cable. The bracket assembly is the connection mechanism between the window regulator and the door glass. The door glass is generally clamped to the bracket assembly, which is then fitted into the guide rail assembly, allowing relative movement between them. The cable assembly is connected to the bracket assembly, and the drive assembly pulls the bracket assembly up and down along the guide rail via the cable assembly, causing the window glass to move up and down along with the bracket assembly. Simultaneously, a slider is attached to the inside of the window glass, and grooves are provided on both sides of the door window to slide along the slider. When the window glass moves up and down with the bracket assembly, it is constrained by the slider and the grooves, moving along the grooves.

[0004] With changes in car design, wider door windows and larger tilt angles have emerged. As a result, the large length difference between the two sides of the glass and the excessive constraint of the slider and the track during the raising and lowering of the window cause jamming and shaking during the process, resulting in poor stability.

[0038] The embodiments of the present invention will now be described in detail with reference to the accompanying drawings.

[0039] Please see Figure 1 and Figure 2A dual-rail zero-step lift device includes a first guide rail 1, a second guide rail 2, a drive assembly 3, a first bracket 4, and a second bracket 5. The first guide rail 1 is fitted onto the first bracket 4, and the second guide rail 2 is fitted onto the second bracket 5. The drive assembly 3 is connected to both the first bracket 4 and the second bracket 5, driving the first bracket 4 to move on the first guide rail 1 and simultaneously driving the second bracket 5 to move on the second guide rail 2. The device also includes a first X-direction adjustment structure mounted on the first bracket 4 and a second X-direction adjustment structure mounted on the second bracket 5, enabling X-direction adjustment of the door glass 6. Specifically, the X-direction is a horizontal direction perpendicular to the lifting direction of the door glass 6. The door glass 6 is mounted on the first bracket 4 and the second bracket 5 using existing technology. Drive assembly 3 adopts existing technology, and its principle is consistent with the structure of the dual-track functional glass lifter with authorization announcement number CN220909469U. Drive assembly 3 includes a coil base 31, a drive source 32, a first cable 33, a second cable 34, and a third cable 35. The coil base 31 is mounted on the first guide rail 1, the drive source 32 is mounted on the coil base 31, the first fixed pulley 11 and the second fixed pulley 12 are disposed at both ends of the first guide rail 1, and the third fixed pulley 21 and the fourth fixed pulley 22 are disposed at... The first cable 33 is positioned at both ends of the second guide rail 2; one end of the first cable 33 is connected to the reel base 31, and the other end passes over the third fixed pulley 21 and connects to the second bracket 5; one end of the second cable 34 is connected to the reel base 31, and the other end passes over the second fixed pulley 12 and connects to the first bracket 4; one end of the third cable 35 passes over the first fixed pulley 11 and connects to the first bracket 4, and the other end passes over the fourth fixed pulley 22 and connects to the second bracket 5. The drive source 32 is linked to the first bracket 4 and the second bracket 5 respectively through the cables. Preferably, the drive source 32 is a motor.

[0040] This utility model discloses a dual-rail zero-step differential lifter. When the car door glass 6 needs to be raised or lowered, the motor is started first. The motor drives the first cable 33, the second cable 34, and the third cable 35 synchronously, thereby causing the first bracket 4 and the second bracket 5 to slide synchronously and in the same direction on the first guide rail 1 and the second guide rail 2, respectively, thus raising or lowering the car door glass 6. When the car door glass 6 moves or deviates during the raising or lowering process, the first X-direction adjustment structure and the second X-direction adjustment structure synchronously provide X-direction clearance space, effectively reducing the phenomenon of jamming or shaking of the car door glass 6 caused by movement or deviation during the raising or lowering process, and improving the stability of the raising and lowering of the car door glass 6.

[0041] Example 1

[0042] Further, please refer to Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 and Figure 14The first bracket 4 is provided with a first constraint post 44, and the door glass 6 is provided with a positioning circular hole 61 that mates with the first constraint post 44. The first bracket 4 is provided with an adjustment groove 41, and the first X-direction adjustment structure includes a first spring piece 42 and a second spring piece 43 disposed in the adjustment groove 41. A gap 411 for clamping the first guide rail 1 is provided between the first spring piece 42 and the second spring piece 43. The first guide rail 1 moves along the X-direction while being clamped by the first spring piece 42 and the second spring piece 43 to achieve X-direction adjustment of the door glass. The second X-direction adjustment structure is the same as the first X-direction adjustment structure. Specifically, the first bracket 4 is provided with a glass clamping spring piece 47, and a glass mounting groove 46 is provided between the glass clamping spring piece 47 and the first bracket 4. The inner wall width of the glass mounting groove 46 is smaller than the thickness of the door glass 6. During assembly, the door glass 6 is pressed into the glass mounting groove 46 using the glass clamping spring 47. The first constraint post 44 is inserted into the positioning round hole 61 through an interference fit. The first bracket 4 and the door glass 6 are matched by the feature of the post and the round hole, so there is no clearance at the position of the round hole, thus the door glass 6 is installed on the first bracket 4 and the second bracket 5. The adjustment groove 41 is provided, which not only provides deformation space for the first spring 42 and the second spring 43 and provides sufficient clearance in the X direction, but also limits the deformation of the first spring 42 and the second spring 43 through its inner wall, that is, the clearance is limited, which satisfies the stable sliding of the first guide rail 1. The width of the gap 411 between the first spring 42 and the second spring 43 is k, and the value of k is less than the thickness h of the first guide rail 1, so that the first guide rail 1 presses against the first spring 42 and the second spring 43, which helps to prevent the first guide rail 1 from vibrating in the pressing direction, achieves a damping effect, and reduces the shaking of the door glass 6. The first spring plate 42 is arched at one end near the inner wall of the adjustment groove 41, with its two ends connected to the inner wall of the adjustment groove 41 to provide space for deformation of the first spring plate 42. Through the combination of the first spring plate 42 and the second spring plate 43, the spring plate itself elastically deforms, adapting to the glass's X-direction clearance movement and providing a certain supporting elasticity to prevent abnormalities such as vibration and jamming of the first bracket 4 during X-direction clearance. Similarly, the second bracket 5 has the same structure as the first bracket 4, forming a second X-direction adjustment structure. The second X-direction adjustment structure and the first X-direction adjustment structure synchronously provide X-direction clearance for any movement or offset during the lifting and lowering of the door glass 6, reducing phenomena such as jamming or vibration during the lifting and lowering of the door glass 6, resulting in good stability during the lifting and lowering of the door glass 6.

[0043] Further, please refer to Figure 4 and Figure 5The first spring plate 42 and the second spring plate 43 include an end guide section 421, a middle pressing section 422, and a bottom support section 423 arranged sequentially. The adjusting groove 41 is provided with a guide portion 412, and the distance d between the inner walls of the guide portions 412 is not less than the opening distance e formed by the two end guide sections 421. Preferably, the first spring plate 42 and the second spring plate 43 are mirror images of each other in the adjusting groove 41. The first spring plate 42 presses against one side of the first guide rail 1, and the second spring plate 43 presses against the opposite side of the first guide rail 1, and the first spring plate 42 and the second spring plate 43 clamp the first guide rail 1. The two sides of the adjusting groove 41 extend outward to form the guide portion 412, and the guide portion 412, in conjunction with the opening of the end guide section 421, facilitates the smooth insertion and assembly of the first guide rail 1. The end face of the middle pressing section 422 near the first guide rail 1 adopts an arc structure, and its arc middle part is pressed and contacted with the first guide rail 1. The end guide section 421 and the bottom support section 423 adopt an arc structure, and the apex of the arc is pressed into contact with the first guide rail 1. The point-to-surface contact with the first guide rail 1 effectively ensures that the first spring piece 42 and the second spring piece 43 maintain pressure contact with the first guide rail 1. The first spring piece 42 and the second spring piece 43 have good deformation sensitivity, which facilitates the movement of the first guide rail 1.

[0044] Further, please refer to Figure 4 The middle pressing section 422 is provided with a cavity 424. Specifically, the shape of the cavity 424 is an ellipse that matches the arc structure. This improves the rapid deformation of the middle pressing spring when it is pressed by the first guide rail 1, resulting in good sensitivity and quickly providing clearance in the X direction.

[0045] Further, please refer to Figure 6 to Figure 9 It also includes a damping spring 45 disposed in the adjustment groove 41. The damping spring 45 is connected to the inner wall of the adjustment groove 41 and presses against the first guide rail 1. Specifically, the middle part of the damping spring 45 is connected to the inner wall of the adjustment groove 41, and the two ends of the damping spring 45 are curved upwards. The arc section of the damping spring 45 contacts the bottom surface of the first guide rail 1 and presses against the first guide rail 1. With this structure, the first guide rail 1 is prevented from vibrating in the pressing direction, achieving a damping effect. The first spring 42 and the second spring 43 press against the first guide rail 1 in the X direction, and the damping spring 45 presses against the first guide rail 1 in the vertical direction, allowing the first bracket 4 to slide smoothly on the first guide rail 1.

[0046] Furthermore, the distance from the side wall of the first guide rail 1 to the inner wall of the guide portion 412 is 'a'; the distance from the edge end face of the first guide rail 1 to the side end face of the buffer spring 45 is 'b'; and the distance from the edge end face of the first guide rail 1 to the inner wall of the corresponding adjustment groove 41 is 'c', where c>b>a. This structure prevents the buffer spring from detaching from the contact surface of the first guide rail 1 during the X-axis movement of the first bracket, and the clearance size is determined by distance 'a'.

[0047] Example 2

[0048] Please seeFigure 3 , Figure 10 , Figure 11 , Figure 12 and Figure 13 The specific implementation of this embodiment is basically the same as that of Embodiment 1, except that the second X-direction adjustment structure is different. Specifically, the first bracket 4 is provided with a first constraint post 44, and the door glass 6 is provided with a positioning circular hole 61 that cooperates with the first constraint post 44; the first bracket 4 is provided with an adjustment groove 41, and the first X-direction adjustment structure includes a pair of mirror-arranged first spring pieces 42 and second spring pieces 43 provided in the adjustment groove 41. A gap for clamping the first guide rail 1 is provided between the first spring pieces 42 and the second spring pieces 43. The first guide rail 1 moves along the X-direction in the clamping of the first spring pieces 42 and the second spring pieces 43 to realize the X-direction adjustment of the door glass; the door glass 6 is provided with a glass clip 62, and the second X-direction adjustment structure includes a second constraint post 51 provided in the second bracket 5 and a clearance square hole 621 provided in the glass clip 62. The second constraint post 51 moves along the clearance square hole 621 in the X-direction. Specifically, the width of the clearance square hole 621 is the same as the outer diameter of the second constraint post 51, and the length of the clearance square hole is greater than the outer diameter of the second constraint post 51. The second constraint post 51 can move in the X direction of the clearance square hole 621, forming a clearance gap m of the second X-direction adjustment structure. When m and a are not equal, the minimum value is taken. Preferably, m = a, to ensure that the clearance of the second X-direction adjustment structure is consistent with the clearance of the first X-direction adjustment structure, which is convenient for control.

[0049] Furthermore, the second bracket 5 is provided with a second guide rail groove 52, the width of which is greater than the thickness of the second guide rail 2. This structure ensures that the clearance of the second X-direction adjustment structure is matched with the clearance feature of the second bracket 5 and the glass clamp 62, facilitating clearance control.

[0050] This utility model discloses a dual-track zero-step differential lifter. When the car door glass 6 needs to be raised or lowered, the motor is first started to drive the car door glass 6 to rise or fall. When the car door glass 6 moves or deviates during the raising or lowering process, the first X-direction adjustment structure and the second X-direction adjustment structure simultaneously provide X-direction clearance space, effectively reducing phenomena such as jamming or shaking of the car door glass 6 caused by movement or deviation during the raising or lowering process. The first X-direction adjustment structure and the second X-direction adjustment structure adopt different clearance structures according to the structure of the glass car door 6, improving the application scenarios. The first spring 42 and the second spring 43 include an end guide section 421, a middle pressing section 422 and a bottom support section 423 arranged in sequence, effectively ensuring that the first spring 42 and the second spring 43 maintain pressure contact with the first guide rail 1.

[0051] The specific embodiments described above further illustrate the purpose, technical solution, and beneficial effects of this utility model. It should be understood that the above description is only a specific implementation method of this utility model and is not intended to limit this utility model. Any modifications, equivalent substitutions, and improvements made within the scope of the spirit of this utility model should be included within the protection scope of this utility model.
