[0057] The present invention will be further described below in conjunction with specific embodiments and the accompanying drawings. More details are set forth in the following description to facilitate a full understanding of the present invention. However, the present invention can obviously be implemented in many other ways different from this description. Those skilled in the art can make similar generalizations and deductions according to the actual application situation without departing from the connotation of the present invention. Therefore, the protection scope of the present invention should not be limited by the content of this specific embodiment.

[0058] It should be noted that these and subsequent other drawings are only examples, and they are not drawn according to the condition of equal proportion, and should not be used to limit the actual claimed protection scope of the present invention.

[0059] The purpose of this application is to solve some problems existing in the window glass lifter in the related art. Specifically, the window glass lifter in the related art is as Figure 1 shown. During the process of the lifter realizing the lifting of the window glass 10, due to the different curvatures of the window glass 10 of different vehicle models, the slide rail 100 of the lifter must be configured separately to match the glass curvature of different window glasses 10. In this way, the versatility of the lifter is poor, and the costs of design, manufacture, testing, after - sales, etc. of the lifter are greatly increased. Therefore, in order to improve the versatility of the lifter, relevant research of the present invention has been carried out, which will be described in detail below.

[0060] Figure 2 This is the structure diagram of the door assembly of the present invention. The lifter of the present invention is installed in the door 20 to realize the lifting of the window glass 10, and thus realize the opening and closing of the window. The specific structure of the lifter is as follows:

[0061] Figure 3 This is the exploded view of the lifter according to an embodiment of the present invention; Figure 4 This is the installation position diagram of the lifter according to an embodiment of the present invention; Figure 5 This is the present invention Figure 4 enlarged view at I. The lifter of the present invention includes a slide rail 100, a slider 200, a mounting seat 300, a flexible mechanism 400, and a driving device 500.

[0062] The slide rail 100 is fixedly installed on Figure 2In the vehicle door 20, the slide rail 100 and the window glass 10 are spaced apart. The slide rail 100 can be a straight slide rail or an arc-shaped slide rail. When the slide rail 100 is a straight line type, its extending direction is consistent with the lifting direction Z of the window glass 10; when the slide rail 100 is an arc-shaped type, its radius of curvature can be arbitrary, and can be the same as or different from the radius of curvature of the window glass 10.

[0063] The slider 200, the flexible mechanism 400 and the mounting seat 300 are combined to form a component. The slider 200 is slidably disposed in the slide rail 100, the mounting seat 300 is directly or indirectly mounted to the window glass 10, and the flexible mechanism 400 is respectively connected to the mounting seat 300 and the slider 200.

[0064] The driving device 500 is fixedly installed in Figure 2 the inner door 20. The driving device 500 is internally provided with a motor, and sleeve 520 is arranged on both sides. The wire wheels 110 are arranged on both sides of the slide rail 100, and the slider 200 is limited to slide between the wire wheels 110 on both sides of the slide rail 100.

[0065] The wire ropes 510 are arranged on both sides of the slider 200. One wire rope 510 on one side of the slider 200 is wound around a wire wheel 110 in sequence, passes through a sleeve 520 to connect to one side of the driving device 500; the other wire rope 510 on the other side of the slider 200 is wound around another wire wheel 110 in sequence, passes through another sleeve 520 to connect to the other side of the driving device 500.

[0066] The driving device 500 can pull one side of the slider 200 through the wire rope 510, so that the slider 200 slides and approaches a wire wheel 110, and then drives the window glass 10 to rise through the flexible mechanism 400 and the mounting seat 300; the driving device 500 can also pull the other side of the slider 200 through the wire rope 510, so that the slider 200 slides and approaches the other wire wheel 110, and then drives the window glass 10 to descend through the flexible mechanism 400 and the mounting seat 300.

[0067] As described above, the radius of curvature of the slide rail 100 and the window glass 10 of the present application can be inconsistent as Figure 6 shown. Therefore, during the lifting process of the window glass 10, when the distance between the slide rail 100 and the window glass 10 changes, in order to adapt to this change, the distance between the mounting seat 300 and the slider 200 will also be adjusted, and the flexible mechanism 400 can adjust its posture to adapt to the change in the distance between the mounting seat 300 and the slider 200, so as to ensure that while the window lifter drives the window glass 10 to continuously lift and lower, it does not affect the sliding of the slider 200 in the slide rail 100.

[0068] In summary, during the raising and lowering process of the window glass 10, the lifter of the present invention can, through the attitude adjustment of the flexible mechanism 400, ensure that the distances between the mounting seat 300 and the slider 200, and between the window glass 10 and the slide rail 100 always match each other. Therefore, the slide rail 100 does not need to be consistent with the curvature radius of the window glass 10, and various costs such as design cost, manufacturing cost, testing and experiment cost, and after-sales optimization cost are greatly reduced, thereby improving the versatility and economy of the lifter.

[0069] Figure 7 It is a view of the lifter from an observation angle in an embodiment of the present invention; Figure 8 It is an embodiment of the present invention Figure 7 An enlarged view of part II; Figure 9 It is a structural diagram of the protrusion in the slider in an embodiment of the present invention. The slider 200 includes a main body part 210 and an ear part 220, and the ear part 220 is connected to the main body part 210; the slide rail 100 includes a main rail 101 and a side rail 102, and the side rail 102 extends from the side of the main rail 101. Among them, the main body part 210 and the main rail 101 are in sliding fit, and the ear part 220 and the side rail 102 are in sliding fit. The sliding fits at the two positions can improve the constraint effect on the movement path of the slider 200, thereby improving the movement accuracy.

[0070] Optionally, during the raising and lowering process of the window glass 10, not only does the distance between the window glass 10 and the slide rail 100 change, but also due to the curved surface structure of the window glass 10 and the guide rail structure of the car door 20, an angle change occurs between the window glass 10 and the slide rail 100. To adapt to this angle change, the present invention adopts the following solution:

[0071] A second chute 221 is provided in the ear part 220, and at least part of the side rail 102 extends into the second chute 221. The top surface and the bottom surface of the second chute 221 face the side rail 102, and the distance between the top surface and the bottom surface of the second chute 221 is greater than the thickness of the side rail 102, so as to have sufficient clearance between the second chute 221 and the side rail 102. Protrusions 222 are provided on both the top surface and the bottom surface of the second chute 221. The protrusions 222 are used to contact the side rail 102, and the protrusions 222 on the top surface and the protrusions 222 on the bottom surface correspond to each other along the thickness direction of the side rail 102. The slider 200 can swing around the protrusions 222 to adjust the inclination degree relative to the slider 200. In this way, through the angle adjustment of the slider 200, the angle change of the window glass 10 during the raising and lowering process can be well adapted, so that the lifter and the window glass 10 have better adaptability.

[0072] Optionally, the protrusion 222 is located at the middle position of the second sliding groove 221, and the surface of the protrusion 222 for contacting the side rail 102 is set as an arc-shaped or spherical surface, so that a line contact or point contact is formed between the protrusion 222 and the side rail 102. In this way, on the one hand, the contact area between the lug part 220 and the side rail 102 can be reduced, and the resistance during the sliding process can be reduced; on the other hand, the structural features of the arc-shaped surface and spherical surface of the protrusion 222 can enable the slider 200 to swing better around the protrusion 222.

[0073] Optionally, as described above, the mounting base 300 can be directly mounted to the window glass 10. For example, a clamping groove is provided on the mounting base 300 to clamp the window glass 10; the mounting base 300 can also be indirectly mounted to the window glass 10 by providing a bracket 600, as follows:

[0074] Figure 10 is a diagram of the mounting position of the bracket in the window lifter according to an embodiment of the present invention; Figure 11 is a diagram of the mounting position of the bracket from another angle according to an embodiment of the present invention. As shown in the figure, the window lifter further includes a bracket 600. One side of the bracket 600 is rotatably connected to the mounting base 300 by inserting a pin shaft or the like, and the other side of the bracket 600 is used to connect to the window glass 10. In this way, the window glass 10 can rotate with the bracket 600 to adjust the inclination degree of the window glass 10 relative to the sliding rail 100, thereby improving the adaptability of the window lifter during the lifting and lowering process of the window glass 10.

[0075] Optionally, for the specific structure of the flexible mechanism 400, the flexible mechanism 400 can be set as an elastic component, and its own elastic deformation is used to adapt to the distance change between the slider 200 and the mounting base 300. In this application, the flexible mechanism 400 is set as a link structure, as follows:

[0076] Please refer to again Figure 4 and Figure 5 , the flexible mechanism 400 includes a first link 410 and a second link 420 that are rotatably connected to each other. The middle parts of the first link 410 and the second link 420 are rotatably connected. One end of the first link 410 is rotatably connected to the slider 200, and the other end is slidably connected to the mounting base 300; one end of the second link 420 is slidably connected to the slider 200, and the other end is rotatably connected to the mounting base 300.

[0077] Specifically, the middle parts of the first link 410 and the second link 420 are rotatably sleeved with the same pin 430 to realize the relative rotation between the two. Pins 430 are fixedly arranged at both ends of the first link 410 and both ends of the second link 420; a first sliding groove 310 is provided on one side of the slider 200, and a through hole 240 is provided on the other side; a first sliding groove 310 is provided on one side of the mounting base 300, and a through hole 240 is provided on the other side.

[0078] The pin 430 at one end of the first link 410 is rotatably arranged in the through hole 240 of the slider 200, and the pin 430 at the other end is slidably arranged in the first chute 310 of the mounting seat 300; the pin 430 at one end of the second link 420 is slidably arranged in the first chute 310 of the slider 200, and the pin 430 at the other end is rotatably arranged in the through hole 240 of the mounting seat 300.

[0079] In this way, the attitude adjustment of the flexible mechanism 400 is specifically as follows: by the sliding of the pin 430 in the first chute 310, the included angle between the first link 410 and the second link 420 will be adjusted to adapt to the change in the distance between the slider 200 and the mounting seat 300 during the lifting and lowering process of the window glass 10.

[0080] Figure 12 It is the structure diagram of the locking device in the window lifter according to an embodiment of the present invention; Figure 13 It is an embodiment of the present invention Figure 12 The enlarged view at III; Figure 14 It is the plan view of the locking device according to an embodiment of the present invention. As shown in the figure, the self-locking device includes a gear 710 and a limit block 720. The limit block 720 is rotatably arranged on the slider 200. At least one of the first link 410 and the second link 420 is provided with the gear 710. The gear 710 is arranged at the rotatable end of the link it is connected to, and the gear 710 can rotate with the connected link. For example, the gear 710 is arranged at the rotatable end of the first link 410 and fixedly sleeved on the pin 430. A key connection can be made between the gear 710 and the pin 430 to keep the synchronous rotation or synchronous locking of the gear 710 and the pin 430. The rotatable end of the first link 410, that is Figure 5 The end where the first link 410 is rotatably connected to the slider 200 in the figure.

[0081] The gear 710 and the limit block 720 can mesh with each other, thereby preventing the gear 710 from rotating, and further locking the flexible mechanism 400 in the current attitude; when the slider 200 moves, the gear 710 and the limit block 720 can be separated from each other, thereby releasing the gear 710 to unlock the flexible mechanism 400 to adjust the attitude.

[0082] In this way, on the one hand, before leaving the factory, the attitude of the flexible mechanism 400 can be fixed, which is convenient for installing the window lifter in the door and installing it on the window glass 10. On the other hand, after the window glass 10 is lifted to an appropriate height, through the attitude fixing of the flexible mechanism 400, the position of the window glass 10 can be hovered, improving the functionality of the window lifter.

[0083] Optionally, the limit block 720 is rotatably arranged on the slider 200. The wire rope 510 is respectively connected to the slider 200 and the limit block 720. The driving device 500 can simultaneously pull the slider 200 and the limit block 720 through the wire rope 510 to drive the limit block 720 to separate from the gear 710 and drive the slider 200 to slide. This can improve the controllability of the limit block 720.

[0084] Please refer to again Figure 3 、 Figure 5 、 Figure 13 and Figure 14 , specifically, a first plug head 721 and a second plug head 722 are arranged in the limit block 720; a first wire rope clamping seat 231 and a second wire rope clamping seat 232 are arranged in the slider 200. The wire rope 510 passing out from one side of the driving device 500 is divided into two strands to be respectively connected to the first wire rope clamping seat 231 and the first plug head 721. When the driving device 500 pulls the wire rope 510 from this side, the limit block 720 rotates counterclockwise to separate from the gear 710, and the wire rope that pulls the slider 200 moves towards the wire wheel 110 on one side to realize the lowering of the window glass 10; while the wire rope 510 passing out from the other side of the driving device 500 is divided into two strands to be respectively connected to the second wire rope clamping seat 232 and the second plug head 722. When the driving device 500 pulls the wire rope 510 from this side, the limit block 720 rotates counterclockwise to separate from the gear 710, and the wire rope that pulls the slider 200 moves towards the wire wheel 110 on the other side to realize the raising of the window glass 10.

[0085] Optionally, the wire rope clamping seat 230 is set as a spring seat, and the wire rope clamping seat 230 is in a tensile deformation state during use. The purpose of this setting is to: tension the wire rope 510 through the tension generated by the wire rope clamping seat 230 itself, ensure the normal use of the wire rope 510, and prevent the loosening of the wire rope 510 during use.

[0086] Optionally, a torsion spring is arranged between the limit block 720 and the slider 200. For example, the torsion spring is respectively connected to the limit block 720 and the slider 200. In this way, when the slider 200 stops sliding, the torsion spring can drive the limit block 720 to reset to engage with the gear 710, and further realize the locking of the flexible mechanism 400.

[0087] Figure 15 is the structure diagram of the window lifter according to another embodiment of the present invention; Figure 16 is the structure diagram of the flexible mechanism according to another embodiment of the present invention; Figure 17 is the structure diagram of the slider according to another embodiment of the present invention; Figure 18This is the structural diagram of the mounting base according to another embodiment of the present invention. As shown in the figure, the first end of the first link 410 is rotatably connected to the first end of the second link 420, and the first end of the first link 410 and the first end of the second link 420 are both rotatably connected to the slider 200; the second end of the first link 410 and the second end of the second link 420 are both slidably connected to the mounting base 300.

[0088] Specifically, the first ends of the first link 410 and the second link 420 are rotatably sleeved on the same pin 430, and at the same time, the pin 430 passes through and is fixed in the through hole 240 of the slider 200. Pins 430 are fixedly provided at the second ends of the first link 410 and the second link 420 respectively. First chutes 310 are respectively provided on two opposite sides of the mounting base 300. The pin 430 at the second end of the first link 410 is slidably disposed in the first chute 310 on one side of the mounting base 300, and the pin 430 at the second end of the second link 420 is slidably disposed in the first chute 310 on the other side of the mounting base 300. Thus, during the lifting process of the window glass 10, the first link 410 and the second link 420 can change the included angle by relative rotation to realize the attitude adjustment of the flexible mechanism 400, and further adapt to the distance change between the slider 200 and the mounting base 300.

[0089] Optionally, a slot 250 is provided on one of the slider 200 and the mounting base 300, and a plug 320 is provided on the other. The plug 320 is movably inserted into the slot 250, and the insertion direction of the plug 320 is the direction in which the slider 200 and the mounting base 300 move away from or close to each other. This can improve the movement accuracy of the mounting base 300 relative to the slider 200 and ensure that there are no abnormalities such as mutual separation and mutual dislocation during the movement process.

[0090] The door assembly disclosed by the present invention is as Figure 2 shown, including a window lifter, a window glass 10, and a door 20. The window glass 10 is slidably installed in the window guide rail of the door 20 along the lifting direction Z. Components such as the slide rail 100 and the driving device 500 of the window lifter are fixed inside the door 20. When the window lifter drives the window glass 10 to rise, the window opening gradually decreases until it closes.
