Detailed Description

The present application is further described below with reference to specific embodiments, and it should be noted that, without conflict, any combination between the embodiments or technical features described below may form a new embodiment.

In the description of the present application, it should be noted that, for the terms of orientation, such as "central", "lateral", "longitudinal", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", etc., it indicates that the orientation and positional relationship shown in the drawings are based on the orientation or positional relationship shown in the drawings, and is only for the convenience of describing the present application and simplifying the description, but does not indicate or imply that the device or element referred to must have a specific orientation, be constructed in a specific orientation, and be construed as limiting the specific scope of protection of the present application.

It is noted that the terms first, second and the like in the description and in the claims of the present application are used for distinguishing between similar elements and not necessarily for describing a particular sequential or chronological order.

In one preferred embodiment of the present application, as shown in fig. 1 and 18, a window guide assembly includes at least one lift rail 3, at least one lift slider 4, and a lift driving device 5. The lifting slide block 4 comprises a supporting block 42 and a traction slide block 41 which are elastically connected with each other; the traction slider 41 can be in sliding fit with the lifting slide rail 3, and the supporting block 42 is used for clamping the window glass 100. When the lifting driving device 5 pulls the traction slider 41 to drive the supporting block 42 and the window glass 100 to move along the lifting slide rail 3 to be closed, the lifting driving device 5 can continue to pull the traction slider 41 to slide along the lifting slide rail 3, and then the supporting block 42 can drive the window glass 100 to move normally through the extrusion fit with the lifting slide rail 3 until the window glass 100 is flush with the outer surface of the window frame 2. Compared with the traditional window guide rail assembly, the window glass 100 can be driven to move synchronously by the normal movement of the supporting block 42 relative to the traction sliding block 41 after the window glass 100 is in a closed state, until the outer surfaces of the window glass 100 and the window frame 2 are flush, and then the surface difference between the window glass 100 and a vehicle door can be reduced or eliminated, so that the driving performance of the vehicle is improved.

It is understood that the elevation slide rail 3 is installed in the door in the elevation direction of the window glass 100. The number of the lifting slide rails 3 can be set according to actual needs, and is at least one; in general, two lifting rails 3 may be provided to improve the supporting strength of the window glass 100. The number of the lifting slide blocks 4 is matched with that of the lifting slide rails 3; and the lifting range of the lifting slider 4 is limited to the inside of the vehicle door. The lifting driving device 5 is a prior art, and its specific structure and operation principle are well known to those skilled in the art, so they will not be described in detail here.

It will also be appreciated that in the use of the window guide rail assembly of the present application in a vehicle, there are a variety of modes of operation for the window glass 100; including but not limited to the following two.

The first working mode is as follows: when the vehicle speed of the vehicle is low, the closing of the window glass 100 is in a conventional closed state. When the vehicle speed is high, the window glass 100 is in a zero-surface-difference state flush with the outer surface of the window frame 2, so that the wind resistance of the vehicle during running is reduced to improve the driving performance.

And a second working mode: when the window glass 100 is closed at any vehicle speed, the window glass 100 is in a zero-surface-difference state.

For the two working modes, the control is performed only by different algorithm programs, and the specific algorithm programs are well known by those skilled in the art.

In this embodiment, as shown in fig. 1 to 3, the lifting slide rail 3 may be fixedly installed in the door through the installation plate 600, so that the whole window guide rail assembly of the present application may be modularized. That is, when the window guide rail assembly is installed, the installation of the whole window guide rail assembly can be realized only by the fixed connection between the installation plate 600 and the inside of the vehicle door. When the door trim is processed, only the position connected to the mounting plate 600 needs to be processed, so that the processing difficulty of the door trim can be reduced.

In this embodiment, as shown in fig. 7, the top of the supporting block 42 is provided for holding the window glass 100. One side of the supporting block 42 is provided with at least one sliding rod 422 which is in sliding fit with the traction sliding block 41, the sliding rod 422 is sleeved with a second spring 720, and the second spring 720 is respectively connected with the sliding rod 422 and the traction sliding block 41. Wherein, at least one slide bar 422 is matched with the lifting slide rail 3 through an extrusion structure. When the window glass 100 is closed and the lifting driving device 5 continues to drag the traction slider 41 to slide, the sliding rod 422 may drive the supporting block 42 to drive the window glass 100 to move in the normal direction by the pressing structure and compress the second spring 720. When the elevating driving unit 5 reversely tows the traction slider 41, the supporting block 42 may perform a returning movement to a closed state by the elastic force of the second spring 720.

It can be understood that the specific number of the sliding rods 422 can be selected according to actual needs, for example, as shown in fig. 7, the number of the sliding rods 422 is three; through the elastic connection of the three sliding rods 422 and the corresponding number of second springs 720, it can be ensured that sufficient elastic force is provided to drive the window glass 100 to reset. The second spring 720 is always kept in a compressed state.

Specifically, as shown in fig. 7, a holding portion 421 for holding the window glass 100 is provided on the top of the supporting block 42; the holding portion 421 is higher than the top of the drawing slider 41 by a distance to ensure that the drawing slider 41 can avoid interference with the edge of the door when the window glass 100 is closed. Meanwhile, the three sliding rods 422 are uniformly distributed along the width direction of the supporting block 42; the middle sliding rod 422 and the lifting sliding rail 3 are matched through an extrusion structure, so that the arrangement of the extrusion structure can be facilitated.

In this embodiment, as shown in fig. 5, 7, 15 and 16, the sliding bar 422 is disposed obliquely with respect to the side of the supporting block 42. The extrusion structure includes a first butting block 321 and a second butting block 423; the first abutting block 321 is disposed on the lifting slide rail 3, and the second abutting block 423 is disposed on an end of the slide bar 422. When the first abutting block 321 and the second abutting block 423 are abutted and matched, the supporting block 42 can perform a motion parallel to the axial direction of the sliding rod 422. The partial movement of the supporting block 42 parallel to the lifting slide rail 3 and the movement of the traction slider 41 are reversely balanced, and the supporting block 42 moves relative to the lifting slide rail 3 along the normal direction of the window glass 100.

It can be understood that the first supporting block 321 and the second supporting block 423 are engaged in a wedge shape along the lifting direction. Therefore, when the first abutting block 321 and the second abutting block 423 are abutted and matched, the sliding rod 422 can be subjected to a driving force along the axial direction, and the supporting block 42 can be driven to drive the window glass 100 to move along the axial direction of the sliding rod 422. At this time, the movement of the supporting block 42 can be divided into a first partial movement parallel to the lifting rail 3 and downward and a second partial movement in the normal direction of the window pane 100. And the abutting fit of the first abutting block 321 and the second abutting block 423 is derived from the ascending motion of the lifting slide block 4 along the lifting slide rail 3. Therefore, the overall upward movement trend of the lifting slider 4 can be exactly offset with the first partial movement of the supporting block 42, so that the supporting block 42 can drive the window glass 100 to only perform the second partial movement relative to the lifting slide rail 3, namely, the movement along the normal direction of the window glass 100.

It will also be appreciated that the distance X required for the window pane 100 to move normally to be flush with the outer surface of the window frame 2 when closed may be set. Then, one skilled in the art can calculate the inclination angle of the sliding rod 422, the required ascending distance of the traction sliding block 41, and the inclination angles of the wedge surfaces of the first abutting block 321 and the second abutting block 423 according to the parameter X.

In one embodiment of the present application, as shown in fig. 5 to 6 and 12 to 16, each lifting slide rail 3 includes a first slide rail 31, a second slide rail 32 and at least one second driving plate 33. The second slide rail 32 is fixedly disposed on the mounting plate 600, and the first abutting block 321 can be disposed inside the second slide rail 32. The first slide rail 31 is elastically slidably mounted to the mounting plate 600 in a normal direction of the window glass 100. The second driving plate 33 is slidably mounted on the mounting plate 600 along the lifting direction of the window glass 100 and is positioned at the side of the first slide rail 31; the second driving plate 33 is matched with the first slide rail 31 through a guide structure. When the window glass 100 is in the closed state, the lifting slider 4 slides from the first slide rail 31 to the second slide rail 32, and the traction slider 41 can pull the second driving plate 33 to drive the first slide rail 31 to move normally to abut against the supporting block 42 through the guiding structure. When the lifting slider 4 continues to slide along the second slide rail 32 to drive the window glass 100 to move normally, the first slide rail 31 can synchronously move normally with the supporting block 42 through the guiding structure, so that the first slide rail 31 can be ensured to always abut against the supporting block 42 to improve the anti-theft performance of the window glass 100.

Specifically, as shown in fig. 4, 7, 13, 15 and 16, an inclined first locking surface 313 is disposed on a side of the top of the first slide rail 31 close to the lifting slider 4. The bottom of the supporting block 42 is provided with a second locking surface 424 on the side close to the lifting slide rail 3. The inclination angles of the first locking surface 313 and the second locking surface 424 are offset, so that when the window glass 100 is in a closed state and a zero-surface-difference state, the supporting block 42 is locked by the abutting fit of the first locking surface 313 and the second locking surface 424.

It is understood that whether the vehicle adopts the first or second operating mode, the window glass 100 is either in a conventional closed state or in a zero-surface-difference closed state after the vehicle is parked. Therefore, in order to ensure the anti-theft effect of the window glass 100, the first slide rail 31 needs to be engaged against the second locking surface 424 of the supporting block 42 through the first locking surface 313.

In this embodiment, the specific number of the second driving plates 33 can be selected according to actual needs. The number of the second driving plates 33 is at least one, and preferably the number of the second driving plates 33 is two. For example, as shown in fig. 3, two second driving plates 33 are respectively disposed on two sides of the first slide rail 31 to ensure that the first slide rail 31 is uniformly stressed when moving in the normal direction.

In this embodiment, as shown in fig. 4, 6, 7, 12 and 14, the top of the second driving plate 33 is provided with a first traction rod 331 near the second slide rail 32, and the side of the traction slider 41 is provided with a second traction rod 411. The guide structure includes a drive slot 330 and a drive block 312 in sliding engagement. The driving block 312 is disposed at a side portion of the first slide rail 31, and the driving slot 330 is disposed at the second driving plate 33 and inclined to an extending direction of the second driving plate 33. When the window glass 100 is in a closed state, the pulling slider 41 can be abutted and matched with the first pulling rod 331 of the second driving plate 33 through the second pulling rod 411, and further can drive the second driving plate 33 to slide in the same direction. During the sliding process of the second driving plate 33, the driving slot 330 and the driving block 312 can cooperate to drive the first slide rail 31 to move toward the normal direction of the supporting block 42 until the first locking surface 313 on the first slide rail 31 abuts against the second locking surface 424 of the supporting block 42. When the window glass 100 moves normally, the pull slider 41 can continue to be abutted against the first pull rod 331 of the second drive plate 33 through the second pull rod 411, and further, the drive slot 330 continues to be engaged with the drive block 312 to drive the first slide rail 31 and the support block 42 to move normally synchronously, so as to ensure that the first locking surface 313 and the second locking surface 424 are always in an abutted state.

It can be understood that there may be a plurality of driving slots 330 and driving blocks 312, and the driving slots and the driving blocks extend in the extending directions of the second driving plate 33 and the first slide rail 31 respectively; thereby, the first slide rail 31 can be ensured to be stressed uniformly when moving in the normal direction.

Specifically, as shown in fig. 4 and 14, the back of the first sliding rail 31 is provided with a plurality of guide rods 311 parallel to the normal direction of the window glass 100, and the first sliding rail 31 is slidably engaged with the mounting plate 600 through the guide rods 311. Meanwhile, the guide rod 311 is sleeved with a first spring 710, and two ends of the first spring 710 are respectively connected with the mounting plate 600 and the guide rod 311, so that the first slide rail 31 and the mounting plate 600 are in elastic sliding fit. So that the first slide rail 31 can be restored by the elastic force of the first spring 710 when the lifting slider 4 performs the descending sliding.

For the sake of understanding, the following description will be made in detail on a specific elevating and lowering process of the window glass 100. Take the above-mentioned operation mode as an example.

Initially, as shown in fig. 1, the window glass 100 is positioned inside the door with the window in an open state. Meanwhile, as shown in (1) of fig. 14, the driving slot 330 on the second driving plate 33 is engaged by the first end and the driving block 312 on the first slide rail 31; and the first spring 710 is in a compressed state.

When the vehicle runs at a low speed or is parked and the window needs to be closed, the method comprises the following steps:

(a) As shown in fig. 11, the lifting driving device 5 pulls the lifting slider 4 to drive the window glass 100 to slide from the lower portion of the first slide rail 31 to the second slide rail 32. At this time, as shown in fig. 12 and 13, the window glass 100 still has a small distance to be completely closed, which may be set to Y. At this time, as shown in fig. 12, the second traction rod 411 of the traction slider 41 is just in contact with the first traction rod 331 of the second driving plate 33. At this time, as shown in fig. 13, the second locking surface 424 on the supporting block 42 and the first locking surface 313 on the first slide rail 31 are spaced apart in both the ascending and descending directions and the normal direction. Meanwhile, a distance also exists between the second abutting block 423 at the end of the sliding rod 422 and the first abutting block 321 on the second sliding rail 32 in the lifting direction, and the value of the distance is Y. At this time, as shown in (1) in fig. 14, the relative positions of the second driving plate 33 and the first slide rail 31 are not changed.

(b) As shown in fig. 15, the lifting driving device 5 pulls the lifting slider 4 to drive the window glass 100 to lift along the second slide rail 32 by a distance Y, so that the supporting block 42 is just contacted with the first abutting block 321 on the second slide rail 32 through the second abutting block 423 at the end of the sliding rod 422. In this process, as shown in fig. 14 (2) and fig. 15, the pulling slider 41 drives the second driving plate 33 to slide for a distance Y in the ascending direction by the abutting engagement of the second pulling rod 411 and the first pulling rod 331 on the second driving plate 33. And the second driving plate 33 is in press fit with the driving slot 330 and the driving block 312 to drive the first slide rail 31 to move normally in a direction close to the supporting block 42 until the second locking surface 424 on the supporting block 42 contacts with the first locking surface 313 on the first slide rail 31. During this process, the first spring 710 is under constant compression.

When the vehicle needs to run at a high speed and the window is in a zero-surface-difference state, as shown in fig. 16, the lifting driving device 5 continues to drag the lifting slider 4 to drive the window glass 100 to lift and slide along the second slide rail 32 until the window glass 100 moves along the normal direction by the distance X to be flush with the outer surface of the window frame 2. Specifically, the supporting block 42 is press-fitted through the second abutting block 423 at the end of the sliding rod 422 and the first abutting block 321 on the second sliding rail 32, so as to drive the supporting block 42 to counteract the total ascending motion of the ascending and descending slider 4 through descending partial motion in the ascending and descending direction, so that the supporting block 42 drives the window glass 100 to move normally relative to the ascending and descending sliding rail 3. In this process, as shown in (3) of fig. 14, the pulling slider 41 drives the second driving plate 33 to continue to slide along the ascending direction by the abutting engagement of the second pulling rod 411 and the first pulling rod 331 on the second driving plate 33, and then the second driving plate 33 continues to slide along the ascending direction by the pressing engagement of the driving slot 330 and the driving block 312, so as to drive the first sliding rail 31 and the supporting block 42 to perform the synchronous normal movement of the contact between the first locking surface 313 and the second locking surface 424. In this process, both the first spring 710 and the second spring 720 are in a compressed state.

When the window needs to be opened, the lifting driving device 5 reversely drags the lifting slide block 4 to firstly slide downwards along the second slide rail 32. During the process of sliding down the lifting slider 4, the second spring 720 drives the support block 42 to drive the window glass 100 to perform the return movement along the normal direction through the return elastic force. Meanwhile, the first spring 710 drives the first slide rail 31 to perform a return movement in the normal direction by a return elastic force. When the first slide rail 31 and the second slide rail 32 are aligned again, the lifting driving device 5 continuously and reversely pulls the lifting slider 4 to slide from the second slide rail 32 to the first slide rail 31 and continuously slide downwards to a required position, so as to meet the requirement of the window opening height of the user.

As can be seen from the above, when the window glass 100 needs to move X distance in the normal direction from the closed state to the zero-difference state, when the window glass 100 is in the zero-difference state, a gap with a distance of X is generated between the inner side of the window glass 100 and the window frame 2, and when the window glass 100 is forced to the inner side direction during high-speed driving or parking of a vehicle, the window glass 100 is prone to shake or retreat, thereby affecting driving safety and anti-theft performance.

To ensure structural stability of the window glass 100 in a zero-surface-difference state and to ensure the antitheft performance of the window glass 100. In one embodiment of the present application, as shown in fig. 8, 9, 17, and 18, the window frame 2 includes a frame body 21 and a pair of support members 22. The outer side of the frame body 21 is provided with a guide groove 2101, the inner sides of the two sides of the frame body 21 are provided with mounting grooves 2102, and the mounting grooves 2102 are communicated with the guide groove 2101. The lifting slide block 4 can drive the window glass 100 to slide along the guide groove 2101, the supporting component 22 is correspondingly installed in the installation groove 2102, and the supporting component 22 can be matched with the lifting slide block 4. When the window glass 100 is moving in the normal direction, the lifter knob 4 may drive the support member 22 to slide toward the guide groove 2101 to support the window glass 100.

Specifically, as shown in fig. 8, the frame 21 includes a first portion adapted to the shape of the window glass 100 and a second portion parallel to the lifting rail 3. The second part of the frame body 21 is positioned in the door and fixedly connected; the first portion of the frame 21 is located above the door. The process of closing the window glass 100 is a process of sliding the window glass 100 toward the first portion along the second portion of the frame body 21 by both sides.

It will be appreciated that the mounting slots 2102 are located in the first and second portions of the frame 21, respectively, such that when the support member 22 is mounted in the mounting slots 2102, the elevator slide 4 can mate with the area of the support member 22 located in the second portion.

It will also be appreciated that the window pane 100 generally has four sides and that at least three sides of the window pane 100 need to be supported in order to ensure that the window pane 100 has sufficient support strength in the normal direction. The side edge of the lower portion of the window glass 100 may be supported by the supporting block 42, so that the supporting component 22 may be conveniently disposed, and the side edges of the window glass 100, which are parallel to the lifting slide rail 3, may be supported.

Specifically, as shown in fig. 9, sliding grooves 210 penetrating in the normal direction are provided on both sides of the frame body 21, and a partition plate 211 having an L-shaped cross section is provided in the extending direction of the sliding grooves 210. The slide groove 210 forms a mounting groove 2102 and a partial guide groove 2101 by a partition 211, and a gap is provided between the partition 211 and the side of the slide groove 210 to allow the mounting groove 2102 and the guide groove 2101 to communicate.

In the present embodiment, as shown in fig. 10, 17 and 18, the support assembly 22 includes a support plate 221, a first drive plate 222 and at least one connecting rod 223. The support plate 221 is L-shaped, and the first plate segment 2211 of the support plate 221 is slidably mounted in the mounting groove 2102, and the second plate segment 2212 of the support plate 221 is located in the guide groove 2101 and parallel to the window glass 100. The first drive plate 222 is slidably mounted in the mounting slot 2102 parallel to the first plate segment 2211 of the support plate 221. The first plate section 2211 of the support plate 221 is hinged to the first driving plate 222 through a connection rod 223, and the connection rod 223 is disposed to be inclined in the extending direction of the first driving plate 222. When the window glass 100 is in the closed state, the window glass 100 and the second plate segment 2212 of the support plate 221 are both located inside the guide groove 2101, and the bottom of the first drive plate 222 is just against the traction slider 41. When the window glass 100 moves to be flush with the outer surface of the frame 21 in the normal direction, the first driving plate 222 can be driven by the pulling slider 41 to move synchronously, and the supporting plate 221 is driven by the connecting rod 223 to move to be flush with the inner side of the window glass 100 in the normal direction.

It can be understood that, in order to ensure that the stress of the supporting plate 221 is uniform and stable, the number of the connecting rods 223 may be provided in plurality, and the plurality of connecting rods 223 are uniformly distributed along the extending direction of the supporting plate 221. Meanwhile, the support plate 221 is slidably fitted in the normal direction of the window glass 100 through both ends and both ends of the mounting groove 2102.

Specifically, as shown in fig. 2, 10, 17, and 18, the first drive plate 222 may be elastically connected to the frame 21 at the lower end thereof by a third spring. Meanwhile, the first driving plate 222 is provided at a lower portion thereof with a drawing plate 2220, and the second driving plate 33 may be engaged with the drawing plate 2220 by the first drawing bar 331 so that the first drawing bar 331 may be just contacted with the drawing plate 2220 by a rise Y distance in the above (b) process. Further, during the subsequent normal movement of the window glass 100, the first traction rod 331 can drive the first driving plate 222 to slide upwards by the abutting engagement with the traction plate 2220.

For ease of understanding, the specific operation of the support assembly 22 is described in detail below.

When the window glass 100 is in the closed state, as shown in fig. 17 (1) and fig. 18 (1), the second plate segment 2212 of the support plate 221 is attached to the inner side of the guide groove 2101, and the window glass 100 is attached to the second plate segment 2212 so that the window glass 100 and the outer surface of the frame body 21 have a distance X.

When the window glass 100 needs to be in the zero plane difference state, as shown in fig. 17 (2) and fig. 18 (2), the traction slider 41 presses the first traction rod 331 through the second traction rod 411 to drive the first driving plate 222 to synchronously ascend. During the process of lifting the first driving plate 222, the connecting rod 223 can deflect around the hinge position of the first driving plate 222, so as to drive the supporting plate 221 to slide along the mounting groove 2102 by the normal X distance, so that the supporting plate 221 can be attached to the inner side of the window glass 100 in the zero-difference state through the second plate segment 2212. In this process, the third spring is in a stretched state.

When the window glass 100 needs to be opened, the second driving plate 33 is moved down, so that the first driving plate 222 can be synchronously moved down in reverse by the elastic force of the third spring. In this process, the first driving plate 222 can drive the connecting rod 223 to perform a reverse deflection, so as to drive the supporting plate 221 to reset.

As can be seen from the above, the length and the deflection angle of the connecting rod 223 can be set arbitrarily according to actual needs, and only the requirement of supporting the window glass 100 is satisfied. In one preferable embodiment, as shown in (2) of fig. 17, when the window glass 100 and the outer surface of the frame body 21 are flush, the extending direction of the connecting bar 223 is parallel to the normal direction of the window glass 100. When the window glass 100 is pressed inward from the outside, the connecting rod 223 is at the force-receiving dead center position, and the maximum supporting force can be provided for the window glass 100.

It should be noted that, in order to enable the zero-plane-difference state of the window glass 100, the guide groove 2101 in the present application is an L-shaped open groove as a whole. Therefore, when the window glass 100 is in the zero-difference state, the inward force applied to the window glass 100 can be supported by the support assembly 22, and the outward force applied to the window glass 100 is not supported.

In this embodiment, both the inner and outer sides can be supported in order to ensure that the window glass 100 is in a zero-surface-difference state. As shown in fig. 9, 17 and 18, at least a part of the side walls of the guide groove 2101 are provided with the stopper surface 212 inclined inward, and the side walls of the window glass 100 are also inclined accordingly. When the window glass 100 is moved to be flush with the outer surface of the frame body 21 in the normal direction, the window glass 100 is abutted against the limiting surface 212 through the inclined side wall. So that both the inner and outer sides of the window glass 100 can be supported.

It will be appreciated that the sealing of the window pane 100 may also be improved by the compression of the window pane 100 against the stop surface 212 by the support assembly 22. Of course, in order to further improve the sealing performance of the window glass 100, an elastic gasket may be attached to the inner wall of the guide groove 2101.

The foregoing has described the general principles, essential features, and advantages of the application. It will be understood by those skilled in the art that the present application is not limited to the embodiments described above, which are merely illustrative of the principles of the application, but that various changes and modifications may be made without departing from the spirit and scope of the application, and these changes and modifications are intended to be within the scope of the application as claimed.
