[0032] Please refer to Figures 1 to 8 As shown, this application provides a window glass lifting device 100. The window glass lifting device 100 is installed in the door panel assembly 1 to drive the lifting of the window glass 2. The window glass lifting device 100 includes a guide rail 3 and a sliding member 4. The sliding member 4 carries the window glass 2 and slides on the guide rail 3 to achieve the lifting of the window glass 2. Among them, a plurality of limiting members 9 are provided on the guide rail 3. The limiting members 9 protrude from the side of the guide rail 3 where the window glass 2 is slidably installed. The limiting members 9 are configured to be able to abut against the window glass 2 when the window glass 2 is in a semi-lowered state and a fully lowered state and shakes towards the side close to the guide rail to reduce the shaking of the window glass 2.
[0033] The window glass lifting device 100 provided by this application includes limiting members 9 that can abut against the window glass 2 when the window glass 2 is in a semi-lowered state and a fully lowered state and shakes inwards to reduce the shaking of the window glass 2. In this way, the tightness of the door can be enhanced, the shaking noise of the window glass 2 when closing the door can be reduced, and the user experience when closing the door can be improved.
[0034] Please refer to Figure 1 and Figure 2 As shown, when the window glass 2 is in a fully closed state, the top and the left and right sides of the window glass 2 are within the window frame 21. Due to the limitation of the window frame 21, the shaking amount of the window glass 2 is relatively small when closing the door at this time; when the window glass 2 is in a semi-lowered state, as Figure 2When in the state shown or in the fully lowered state where it has completely dropped into the door panel assembly 1, since the top of the window glass 2 and a part of the left and right sides are separated from the window frame 21, when closing the door at this time, the window glass 2 shakes greatly and will generate abnormal noises, affecting the user experience.
[0035] Please refer to Figures 3 to 6 As shown, in this embodiment, the sliding member 4 is installed on one side of the guide rail 3, and the lower end of the window glass 2 is fixed to the sliding member 4 and can slide along with the sliding member 4 on one side of the guide rail 3. In this embodiment, the window glass 2 slides on the outer side surface of the guide rail 3. When the window glass 2 is impacted when closing the door, when the window glass 2 shakes inward, it will contact the limiting member 9 provided on the guide rail 3 to reduce the shaking. As Figure 6 shown, when the window glass 2 is in the normal position, there is a spacing between the limiting member 9 and the window glass 2 to prevent the window glass 2 from contacting and rubbing against the limiting member 9 during the normal lifting and lowering process, resulting in unsmooth lifting and lowering and wear. In this embodiment, the plurality of limiting members 9 are provided at positions above the middle of the guide rail 3 so that when the window glass 2 is in the semi-lowered state and the fully lowered state, the limiting member 9 can limit the shaking of the window glass 2 near the upper end. As Figure 3 In the figure, the position indicated by a is the position of the sliding member 4 when the window glass 2 is in the semi-lowered state, and the position indicated by b is the position of the sliding member 4 when the window glass 2 is in the fully lowered state. Specifically, in this embodiment, there are two guide rails 3. Among them, two limiting members 9 are provided on the guide rail 3 closer to the front side in the vehicle traveling direction, and one limiting member 9 is provided on the guide rail 3 relatively closer to the rear side in the vehicle traveling direction. Since during the dropping process of the window glass 2, usually the side of the window glass 2 closer to the front side in the vehicle traveling direction first completely separates from the window frame 21, that is, at the semi-lowered state, the front end of the window glass 2 completely separates from the window frame 21 while a part of the rear end of the window glass 2 is still in the window frame 21. Therefore, using two limiting members 9 for the front side of the window glass 2 can provide stable support and limitation for the front end of the window glass 2, and the rear side of the window glass 2 is stably supported and limited by the window frame 21 and one limiting member 9. Of course, in other embodiments, the number of the limiting members 9 can be set to be more. In this embodiment, the limiting member 9 is an elastic block detachably installed on the guide rail 3, such as a rubber block. A card slot is provided on the guide rail 3, and a buckle 91 that is engaged with the card slot is provided on the elastic block. The elastic block is installed on the guide rail 3 by elastically deforming the buckle 91 and inserting it into the card slot. In other embodiments, the limiting member 9 can also be connected to the guide rail 3 by means of screws, bonding, etc. In this embodiment, the guide rail 3 is also provided with structures such as ribs to enhance the structural strength of the guide rail 3, improve the stability of the lifting and lowering of the window glass 2, and reduce the vibration of the lifting device itself at the moment of closing the door.
[0036] Please refer to Figures 3 to 5 As shown, the slider 4 is driven by a power member 5 through a pull rope 6. That is, the window glass lifting device 100 includes a power member 5 and a pull rope 6 connected between the power member 5 and the slider 4. Further, the window glass lifting device 100 further includes an elastic biasing member 8 that applies a force to the pull rope 6 to keep the pull rope 6 taut. By providing the elastic biasing member 8, it is possible to prevent abnormal noises caused by the loosening of the pull rope 6 during long-term use. In some embodiments, the elastic biasing member 8 is a spring; in other embodiments, the elastic biasing member 8 can also be other elastic members such as elastic sheets. Please refer to Figure 7 As shown, in this embodiment, the power member 5 is mounted on a mounting seat 51, and a movable sleeve 81 is movably assembled on the mounting seat 51; specifically, a mounting hole 510 is formed on the mounting seat 51, and the movable sleeve 81 is axially slidably assembled in the mounting hole 510. The pull rope 6 includes a rope core 61 and a tube sleeve 62 sleeved outside the rope core 61. The movable sleeve 81 and the mounting hole 510 allow the rope core 61 to pass through and prevent the tube sleeve 62 from passing through. The elastic biasing member 8 is sleeved on the movable sleeve 81 to elastically bias the movable sleeve 81 in a direction away from the mounting seat 51. In the daily use state, the elastic biasing member 8 is in a state of being compressed and deformed to continuously provide a force to tighten the pull rope 6. When the pull rope 6 has a certain amount of loosening deformation, the elastic biasing member 8 elastically deforms and recovers to offset the loosening deformation amount of the pull rope 6, thereby keeping the pull rope 6 taut.
[0037] Please refer to Figure 8 As shown, in order to reduce the impact between the pull ropes 6, or between the pull rope 6 and the window glass 2 or other components when closing the door, a protective sleeve 7 is also sleeved on the pull rope 6 in this embodiment. A plurality of flexible convex teeth 71 are provided on the outer peripheral wall of the protective sleeve 7, and the flexible convex teeth 71 can play a role in buffering and noise reduction during impact. In this embodiment, the protective sleeve 7 is made of EPDM (Ethylene Propylene Diene Monomer) foamed material, which has good buffering and shock absorption effects. In other embodiments, the protective sleeve 7 can also be made of other rubber or elastic materials. The protective sleeve 7 can be sleeved on a part of the pull rope 6 or on the entire outer surface of the pull rope 6; the flexible convex teeth 71 are strip-shaped and extend parallel to the axis of the protective sleeve 7.
[0038] For the window glass lifting device 100 provided in this application, when closing the door when the window glass 2 is in the half-lowered state or fully lowered state, the inward swaying of the window glass 2 will be blocked by the limiting member 9, reducing the abnormal noise caused by the swaying of the window glass 2; when the pull rope 6 sways and hits other components, the impact sound will be reduced due to the buffering effect of the protective sleeve 7; the looseness generated during the long-term use of the pull rope 6 will be offset by the elastic deformation of the elastic biasing member 8, so that the pull rope 6 can maintain a tensioned state during long-term use. The solution of this application has the remarkable effects of reducing the abnormal noise caused by the swaying of the window glass 2, enhancing the tightness of the door, and improving the use experience when closing the door.
[0039] This application also provides a door, which includes a door panel assembly 1, a window glass 2, and the window glass lifting device 100 as described in the above embodiments. The window glass lifting device 100 is installed inside the door panel assembly 1, and the window glass 2 can rise to be exposed outside the door panel assembly 1 and descend to be received inside the door panel assembly 1. This application also provides a vehicle, which includes the door as described above.
[0040] From the description of the specific embodiments above, it can be seen that for the window glass lifting device 100 provided in this application, a number of limiting members 9 are provided on the guide rail 3. The limiting members 9 protrude from the side of the guide rail 3 where the sliding member 4 and the window glass 2 are installed. The limiting members 9 are configured to be able to abut against the window glass 2 when the window glass 2 sways inward in the half-lowered state and fully lowered state to reduce the swaying of the window glass 2. In this way, the abnormal noise caused by the swaying of the window glass 2 can be reduced, the tightness of the door can be enhanced, and the use experience when closing the door can be improved.
[0041] The technical features of the above-described embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered to be within the scope described in this specification.
[0042] The above-described embodiments only represent several implementation manners of this application. Their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the patent application. It should be noted that for those of ordinary skill in the art, without departing from the concept of this application, several modifications and improvements can still be made, and these all belong to the protection scope of this application. Therefore, the patent protection scope of this application should be subject to the appended claims.
