[0036] The specific implementation of the present invention will be further explained in detail below by describing the best embodiment with reference to the accompanying drawings.

[0037] A glass lifter assembly with an integrated glass guide groove comprises a front lower guide groove assembly 3, a rear lower guide groove assembly 4, a drive assembly 1 and a wire rope assembly 2; the front lower guide groove assembly 3 comprises a front slide rail 31, with pulley structures 5 connected at both ends of the front slide rail 31; a front slider 35 is provided on the front slide rail 31; the front slide rail 31 is connected to a front lower guide groove 34; the rear lower guide groove assembly 4 comprises a rear lower guide groove 41; the pulley structures 5 are connected at both ends of the rear lower guide groove 41, and a rear slider 44 is arranged in the area between the pulley structures 5 at both ends of the rear lower guide groove 41; the drive assembly 1 ... the front slide rail 31 is provided with a front slider 35; the front slide rail 31 is connected to a front lower guide groove 34; the rear lower guide groove assembly 4 comprises a rear lower guide groove 41 The dynamic assembly 1 is connected to the front slider 35 in the front lower guide groove assembly 3 and the rear slider 44 in the rear lower guide groove assembly 4 through a wire rope assembly; the glass lifter assembly disclosed in the present invention is essentially a double-arm glass lifter, but the difference between the glass lifter assembly disclosed in the present invention and the prior art mainly lies in that the glass lifter assembly disclosed in the present invention integrates the guide groove structure used for traditional glass lifting. The glass lifter of the present invention has a front lower guide groove 34 and a rear lower guide groove 41, which reduces the glass lifting problem caused by the traditional lifter assembly, glass guide groove and the accumulated tolerance after installation on the vehicle door.

[0038] The glass lifter assembly disclosed in the present invention can reduce the cumulative error of the traditional guide groove and the glass lifter being separately installed on the vehicle door by integrating the guide groove structure.

[0039] Specifically, the front lower guide groove assembly 3 in the present invention:

[0040] It mainly includes a front slide rail 31: the front slide rail 31 is a rigid extrusion part, arranged along the Z direction of the car door; pulleys are fixed at both ends (one on the upper and one on the lower) to form the turning fulcrum of the wire rope 21.

[0041] Front slider 35 is nested on the front slide rail 31 , and can slide along the front slide rail 31 while bearing the main weight of the door glass 1-3 and the main positioning of the glass in the Z direction.

[0042] Front lower guide groove 34: The overall structural cross-section is U-shaped and is connected to the front slide rail 31 through the front bracket; the upper end of the front lower guide groove 34 is connected to the upper guide groove 1-4 of the car door, forming a "semi-closed" guide channel at the lower edge of the glass.

[0043] The essential function is to guide and limit the lateral position of the door glass 1-3 when it is lowered.

[0044] In the present invention, the front lower guide groove 34 and the front bracket can be made into an integrated structure or a split structure, and the specific design can be based on actual requirements.

[0045] In the present invention, the rear lower guide groove assembly 4 mainly includes a rear lower guide groove 41: the rear lower guide groove 41: the cross-section is also U-shaped; the rear lower guide groove assembly 4 of the present invention has no rear expensive design, and the pulley structure 5 in the rear lower guide groove assembly 4 of the present invention is connected to the two ends of the rear lower guide groove 41; that is, pulleys are connected to both ends of the rear lower guide groove 41.

[0046] The rear slider 44 is mainly directly connected to the wire rope assembly 2, which is equivalent to floating in the inner cavity of the car door. When used later, it is directly connected to the car door glass 1-3 and is only pulled by the wire rope 21; its Z-axis position adapts to the tension of the wire rope 21, and plays an auxiliary positioning and torsion compensation role during actual use.

[0047] The rear bracket is mainly a mounting bracket, which is mainly suitable for mounting and fixing the rear lower guide groove assembly 4 on the vehicle door, and is convenient for arranging and placing the pulley structure 5 in the rear lower guide groove assembly 4.

[0048] In the present invention, the drive assembly 1 mainly includes a metal 8-tooth motor + a worm gear reducer, and steel wire ropes 21 are led out from both ends of the output shaft to form an H-shaped rope winding loop; the three mounting points of the motor housing are directly fixed on the door sheet metal.

[0049] The wire rope assembly 2 mainly includes a high-strength wire rope 21, and the wire rope 21 is covered with a wear-resistant sheath. The wire rope 21 assembly is connected to the front slider 35 and the rear slider 44. The connection method can refer to the existing double-arm window lifter.

[0050] In the present invention, the pulley structure 5 mainly includes a pulley, which is mainly arranged on the upper bracket or the rear bracket, and is used to control the routing trajectory of the wire rope 21. At the same time, in conjunction with the pulling of the drive assembly 1, the front slider 35 and the rear slider 44 can be tensioned.

[0051] Based on the above design, the present invention has the following effects:

[0052] 1. Simplified structure: The traditional rear slide rail is eliminated and the rear slider 44 is "suspended" on the wire rope 21, which reduces the number of parts and the weight of the assembly.

[0053] 2. Improved precision: The front lower guide groove 34 and the rear lower guide groove 41 are equivalent to being integrated into a traditional glass lifter, reducing the size matching between the traditional lifter and the front lower guide groove 34 and the rear lower guide groove 41, and reducing the size chain matching between the lifter and the door lower guide groove. By controlling the precision of the lifter assembly, the precision of the lifting system is improved, ensuring the lifting and lowering stability of the glass lifting system.

[0054] 3. Operation quality: The flexible guide of the steel wire rope 21 and the adaptive function of the rear slider 44 effectively absorb the torsion of the glass and the tolerance of the vehicle body, which is beneficial to reduce vibration and noise.

[0055] 4. Easy assembly: After the lifter is integrated with the guide groove, installation can be completed by positioning it in the door once, which shortens the installation cycle and reduces the number of door sheet metal welding tools.

[0056] Furthermore, in the present invention, the rear slider 44 and the rear lower guide groove 41 are spaced apart. In the present invention, the rear slider 44 and the lower guide groove are spaced apart to avoid friction between the rear slider 44 and the rear lower guide groove 41 when the rear slider 44 moves.

[0057] The rear slider 44 is connected to the drive assembly 1 only through the wire rope 21, and does not directly contact or slide with the rear lower guide groove 41. A preset gap is always maintained between the two (usually 2-5mm, which can be adjusted according to the glass size and door sheet metal tolerance).

[0058] The rear lower guide groove 41 only serves as a guide channel for the lower edge of the glass. Its U-shaped notch maintains a conventional fit with the glass, but does not assume the guiding or supporting function of the rear slider 44.

[0059] This spacing design enables the rear slider 44 to form a "floating positioning": when the glass is twisted due to manufacturing tolerances or door deformation, the rear slider 44 can adaptively adjust its position to avoid jamming or wear of the sealing strip caused by forced constraints.

[0060] Tolerance compensation: Utilizing the elasticity and spacing of the steel wire rope 21, the deviation of the glass itself is automatically absorbed, which is beneficial to improving the smoothness of the lifting and lowering of the door glass 1-3.

[0061] Weight reduction and noise reduction: the friction pair of the rear slide rail and slider is eliminated, reducing the number of parts and sliding noise.

[0062] The rear slider 44 floats to avoid applying extra lateral force to the glass, the compression of the sealing strip is uniform, and the durability is extended.

[0063] Furthermore, in the present invention, a front bracket is provided on the front slide rail 31, and the pulley structure 5 in the front lower guide groove assembly 3 is arranged on the front bracket; in the present invention, the front bracket is both an installation interface between the slide rail and the door sheet metal and a bearing base for the pulley structure 5.

[0064] In addition, in the present invention, a front lower guide groove 34 is provided on the front bracket; the front bracket includes a front upper bracket 32 ​​and a front lower bracket 33, and the front upper bracket 32 ​​and the front lower bracket 33 are distributed at both ends of the front slide rail 31; the two ends of the front slide rail 31 are connected to the vehicle door through the front upper bracket 32 ​​and the front lower bracket 33 respectively; the front lower guide groove 34 is set on the front upper bracket 32; in the present invention, the rigid bracket is composed of two sections, the front upper bracket 32 ​​and the front lower bracket 33, which are respectively fixed to the upper and lower ends of the front slide rail 31 to form a "double-point" cantilever structure; the front upper bracket 32 ​​and the front lower bracket 33 are respectively rigidly fixed to the upper and lower end surfaces of the front slide rail 31 to form a "double-cantilever" structure that is symmetrical up and down; both brackets have vehicle door mounting holes, so that the front slide rail 31 is directly locked to the vehicle door inner panel through the front upper bracket 32 ​​and the front lower bracket 33, without the need for additional transition brackets.

[0065] A pulley structure 5 is provided on the front upper bracket 32 ​​and the front lower bracket 33 respectively. The pulleys in the pulley structure 5 are respectively embedded in the bearing seats of the front upper bracket 32 ​​and the front lower bracket 33, and the pulley axis is perpendicular to the length direction of the front slide rail 31; after the wire rope 21 is turned by the pulley, it forms a "top-to-bottom symmetrical" traction force system with the front slider 35, reducing the unbalanced load of the front slider 35.

[0066] The front lower guide groove 34 and the front upper bracket 32 ​​are generally an integrated structure. Such a setting can avoid the trouble of additional connection process between the front lower guide groove 34 and the front upper bracket 32. Of course, this does not mean that the two cannot be used with a split structure.

[0067] Based on the above design, the present invention has the following advantages:

[0068] 1. Assembly precision: the front slide rail 31, the front lower guide groove 34 and the door are in a straight line, and the lateral bounce of the glass lifting and lowering is reduced throughout the entire stroke.

[0069] 2. The front lower guide groove 34 is equivalent to being integrated on the front slide rail 31, eliminating the traditional independent guide groove bracket, reducing the number of assembly parts; and reducing the overall number of vehicle doors.

[0070] 3. The modular unit is installed as a whole, avoiding the trouble of traditional split installation of the front slide rail 31 and the front lower guide groove 34, which is conducive to improving the production cycle of the vehicle door.

[0071] Furthermore, in the present invention, the front lower guide groove 34 includes a front guide base provided on the front upper bracket 32, and a front groove portion is provided on the front guide base; the horizontal cross-section of the front lower guide groove 34 is U-shaped; in the present invention, the front guide base is the basic structure of the front lower guide groove 34, and the front groove portion is mainly used to limit the running trajectory of the door glass 1-3; the opening direction of the front groove portion is generally set along the X direction of the entire vehicle when the door is closed.

[0072] In the present invention, the leading base is generally designed as an integral structure with the front upper bracket 32. Such a configuration can avoid the trouble of connecting the front upper bracket 32 ​​with the front guide groove during subsequent installation.

[0073] Furthermore, a rear bracket is provided on the rear lower guide groove 41 in the present invention; the pulley structure 5 in the rear lower guide groove assembly 4 is provided on the rear bracket; the setting of the rear bracket of the present invention serves as a mounting part, which is mainly used to facilitate the installation of the rear lower guide groove 41 on the vehicle door, and also facilitates the arrangement and placement of the pulley structure 5.

[0074] In the present invention, the rear bracket includes a rear upper bracket 43 and a rear lower bracket 42, and the rear upper bracket 43 and the rear lower bracket 42 are distributed at both ends of the rear lower guide groove 41; the rear upper bracket 43, the rear lower guide groove 41 and the rear lower bracket 42 form a C-shaped structure; the rear lower guide groove 41 is connected to the vehicle door through the rear upper bracket 43 and the rear lower bracket 42; based on this design, a laterally open trough structure is formed between the rear upper bracket 43, the rear lower guide groove 41 and the rear lower bracket 42, and the subsequent rear slider 44 is arranged in the trough structure; the rear upper bracket 43 and the rear lower bracket 42 act as upper and lower connecting frames, which are convenient for the installation and limitation of the rear slider 44.

[0075] Furthermore, in the present invention, the rear lower guide groove 41 includes a rear guide base, which is provided with a rear groove portion; the horizontal cross-section of the rear lower guide groove 41 is U-shaped; the rear guide base is the main structure of the rear lower guide groove 41, and the rear groove portion is used to limit the downward movement of the door glass 1-3.

[0076] At the same time, in the present invention, the rear upper bracket 43 and the rear lower bracket 42 are distributed on the same side of the rear guide base; such a setting can facilitate the connection between the rear upper bracket 43 and the rear lower bracket 42 and the vehicle door, and avoid the rear upper bracket 43 and the rear lower bracket 42 being distributed on both sides of the rear guide base to affect the subsequent direct fitting and positioning with the vehicle door body.

[0077] In the present invention, the rear upper bracket 43, the rear guide base, and the rear lower bracket 42 are fixedly connected to form a C-shaped closed frame by bolts, riveting / laser welding; the C-shaped opening is along the X direction of the vehicle when the door is closed, and the bolt holes of the rear upper bracket 43 and the rear lower bracket 42 are installed and connected to the door inner panel to form a self-enclosed torsional rigid frame, which can significantly improve the bending stiffness compared with traditional split brackets.

[0078] The pulleys in the pulley structure 5 are respectively pressed into the bearing seats of the rear upper bracket 43 and the rear lower bracket 42, and the pulley shaft is perpendicular to the longitudinal center line of the rear guide base; after the corresponding wire rope 21 passes through the upper and lower pulleys, it pulls the rear slider 44 to perform floating motion in the laterally opened trough structure.

[0079] The rear guide base is an aluminum extrusion or a steel plate bending piece, and the horizontal section is in U shape, the groove width and the groove depth are consistent with the front groove part; the rear upper support 43 and the rear lower support 42 are located on the same side (C type inner side) of the rear guide base, and the shape of the fitting surface of the rear upper support 43 and the rear lower support 42 and the corresponding area of the door inner plate is required to be the same, so as to avoid installation interference with the door inner plate.

[0080] In the application, the C-shaped closed frame directly transmits the stress of the guide groove to the door panel, which is beneficial to guarantee the service life of the rear lower guide groove 41 and reduce the shaking of the rear lower guide groove 41.

[0081] The rear lower guide groove 41 is connected with the rear upper support 43 and the rear lower support 42, the rear upper support 43 and the rear lower support 42 can be used as the mounting support of the rear lower guide groove 41 and also as the mounting support of the glass lifter, which saves the space in the thickness direction of the door compared with the traditional "guide groove + independent support" scheme, and simplifies the assembly process.

[0082] A door assembly, comprising a door body 1-2, a door glass 1-3 arranged on the door body 1-2, and a glass lifter assembly connecting the door glass 1-3 with the door body 1-2; the glass lifter assembly mainly comprises a front lower guide groove assembly 3, a rear lower guide groove assembly 4, a driving assembly 1 and a steel wire rope assembly 2; the lower edge of the door glass 1-3 is connected to a front sliding block 35 in the front lower guide groove assembly 3 and a rear sliding block 44 in the rear lower guide groove assembly 4 respectively; when the door glass 1-3 is lowered, the U-shaped groove part of the front lower guide groove 34 and the rear lower guide groove 41 can be operated.

[0083] The upper guide groove 1-4 is fixed at the window frame and cooperates with the front lower guide groove 34 and the rear lower guide groove 41 to form a lateral guide for the glass.

[0084] The front sliding block 35 and the rear sliding block 44 are respectively linked to the lower edge of the door glass 1-3.

[0085] The driving assembly 1 pulls the two sliding blocks through the steel wire rope assembly 2, and drives the door glass 1-3 to rise and fall on the front sliding rail 31.

[0086] When the operation is between the front lower guide groove 34 and the rear lower guide groove 41, the front lower guide groove 34 and the rear lower guide groove 41 limit the lateral direction of the window glass operation.

[0087] In the application, the front lower guide groove 34 and the rear lower guide groove 41 are bolted to the door inner plate through the respective supports.

[0088] Furthermore, in the present invention, the front lower guide groove 34 and the rear lower guide groove 41 in the window lifter assembly are arranged relative to each other; the door body 1-2 is provided with an upper guide groove 1-4; the front lower guide groove 34 and the rear lower guide groove 41 are respectively distributed at the two ends of the upper guide groove 1-4; based on the above design, the window glass can be facilitated to smoothly transition between the upper guide groove 1-4 and the front lower guide groove 34 or the rear lower guide groove 41.

[0089] In the present invention, it is generally required that the upper guide grooves 1-4 be installed on the door inner panel together with the window lifter assembly first, because after the positions of the upper guide grooves 1-4 are determined, they can serve as the installation references for the front lower guide grooves 34 and the rear lower guide grooves 41, and further can serve as the installation references for the window lifter assembly of the present invention. Such an arrangement can avoid the glass lifter assembly being installed misaligned, resulting in the front lower guide grooves 34 and the rear lower guide grooves 41 not being able to correspond with the upper guide grooves 1-4, and avoid the smooth operation of the subsequent vehicle window glass being affected by the misalignment between the upper guide grooves 1-4 and the front lower guide grooves 34 and the rear lower guide grooves 41.

[0104] 2.2 Rear lower guide groove assembly 4;

[0105] A rear upper bracket 43 and a rear lower bracket 42 are connected to both ends of the rear guide base respectively.

[0106] The rear upper bracket 43, the rear lower bracket 42, and the rear guide base are laser welded into a C-shaped closed frame; the C-shaped opening faces the front of the vehicle when the vehicle door is closed.

[0107] The rear upper bracket 43 and the rear lower bracket 42 are provided on the inner panel of the door and can be fixed by bolts;

[0108] A pulley is provided on each of the rear upper bracket 43 and the rear lower bracket 42 , and the line connecting the center points of the two pulleys on the rear upper bracket 43 and the rear lower bracket 42 is required to be arranged parallel to the front slide rail 31 .

[0109] The rear slider 44 is directly fixed on the steel wire rope 21 and moves along with the steel wire rope 21 during subsequent use.

[0110] 8.3 Drive assembly 1

[0111] 8-tooth metal motor + worm gear reducer, rated output torque; three mounting points directly locked to the inner door panel.

[0112] 2.4 Wire rope assembly 2

[0113] The stainless steel rope is covered with a PA12 sheath and is wound around the motor pulley, the front upper bracket 32, the front lower bracket 33 pulley, the rear upper bracket 43 and the rear lower bracket 42 pulley to form an H-shaped loop.

[0114] Example 2:

[0115] like Figure 1 As shown, the present invention discloses a glass lifter assembly with integrated glass run channel.

[0116] It mainly solves the requirements of achieving smooth operation of the larger door glass 1-3 of light trucks while taking into account the weight and cost competitiveness.

[0117] Specifically, if Figures 1 to 4 As shown, the window lifter assembly of the present invention includes a drive assembly 1, a front lower guide groove assembly 3, a rear lower guide groove assembly 4 and a wire rope assembly 2.

[0118] The glass lifter assembly of the present invention also adopts a structure similar to that of a double-slide rail lifter to achieve smooth lifting and lowering operation; however, the present invention does not provide a traditional rear slide rail structure.

[0119] The front lower guide groove assembly 3 includes a front slide rail 31 , a front lower guide groove 34 and a front bracket.

[0120] The rear lower guide groove assembly 4 includes a rear lower guide groove 41 and a rear bracket.

[0121] Based on the above cooperation, a high degree of integration is achieved between the lower section guide groove of the glass and the lifter, avoiding the problems of long dimensional chain and large cumulative tolerance caused by the traditional installation or welding of the lower guide groove on the inner panel of the door, which leads to large resistance to glass lifting or lifting, difficulty in lifting, abnormal noise, etc.

[0122] At the same time, in order to achieve weight reduction and cost reduction, the rear slide rail is optimized and cancelled, and the rear slider 44 is directly fixed on the wire rope 21. The two sliders in the glass lifter assembly of the present invention adopt the form of one positioning and one installation of the slider and the glass. In addition, the front slider 35 and the rear slider 44 are connected to the car window glass at multiple points to achieve uniform force on the front and rear side window glass and smooth rising operation.

[0123] Although the glass lifter assembly of the present invention adopts a structure similar to that of a traditional double-slide rail lifter, it does not use a rear slide rail structure. At the same time, the present invention adopts two front and rear slider structures to achieve the simultaneous up and down movement of the glass by the front and rear mounting points of the lifter.

[0124] The front slider 35 is connected to the front slide rail 31 , and the rear slider 44 is directly fixed to the corresponding steel wire rope 21 .

[0125] The lifter assembly is integrated with the lower sections of the front and rear glass guide grooves, achieving a high degree of integration between the lifter and the guide grooves.

[0126] The drive motor in the drive assembly 1 adopts a metal 8-tooth motor, which can withstand the larger weight and resistance of the door glass 1-3 and have a large lifting force. The mounting point adopts a 3-mounting point bracket structure, which is easy and stable to install.

[0127] The beneficial effects of adopting the above technical solution are:

[0128] The performance requirements for the larger door glass 1-3 of the door family are smooth and low-noise lifting operation;

[0129] The lifter assembly is integrated with the lower sections of the front and rear guide grooves, which has high integration, small cumulative tolerance and good assembly processability; the elimination of one rear slide rail reduces the weight and cost of the assembly.

[0130] In addition, because the glass lifter assembly disclosed in the present invention is suitable for light truck doors, and since the glass 1-3 of light truck doors is relatively large, a double-slide rail and rope pulley glass lifter is required to achieve smooth operation. However, considering lightweight and low cost, one lifter slide rail at the rear end of the lifter is eliminated, and the lifter slider is directly fixed to the rear end wire rope 21. The front slider 35 plays the main role of lifting gravity and positioning the glass in the X direction, and the rear slider 44 plays an auxiliary role of X-direction positioning. At the same time, it can be appropriately adjusted according to the distance between the loaded glass and the inner grooves of the front and rear slide rails, thereby ensuring the smoothness of the glass lifting and sealing effect.

[0131] In order to reduce the glass lifting problems caused by the accumulated tolerances of the lifter, glass guide groove and after installation on the vehicle door, the front and rear glass lower guide grooves are integrated into the lifter assembly, reducing the matching dimensional chain between the lifter and the door lower guide groove. By controlling the accuracy of the lifter assembly, the accuracy of the lifting system is improved, ensuring the lifting stability of the glass lifting system.

[0132] Obviously, the specific implementation of the present invention is not limited to the above-mentioned methods. As long as various non-substantial improvements are made using the method concept and technical solution of the present invention, they are all within the scope of protection of the present invention.
