Description

Technical Field

[0001] The utility model relates to the technical field of vehicles, in particular to a cross-double-line fixed glass lifter. Background Art

[0002] As an essential component in modern automobiles, the development of window regulators has been driven by a constant pursuit of convenience, safety, and durability. Early window regulators were mostly manually operated. With technological advancements and the growing demand for automation, electric window regulators have gradually become mainstream. This shift not only improves operational convenience but also enables more precise control through motor drive, enhancing the user experience.

[0003] The core function of an electric window lifter is to rapidly raise and lower the glass through electric drive. Specifically, when the user initiates a command via a switch, the power motor receives the signal and starts, converting rotational motion into linear motion through internal transmission mechanisms such as gears or worm gears. This power is transmitted to a steel cable via a winch assembly. One end of the cable is fixed to the winch, and the other end is connected to the column slider and glass bracket. As the winch rotates, the cable is pulled, driving the column slider up and down along the lifter column slide, thereby raising and lowering the door and window glass. Throughout this process, the glass guide groove and the wire rope guide plate remain parallel, ensuring smooth and linear glass lifting.

[0004] However, while existing traditional window lift designs meet basic functional requirements to a certain extent, they still present some significant technical challenges. First, the single-point fixing method makes the central fixing point of the steel wire rope susceptible to wear and tear during long-term, high-frequency reciprocating motion. This wear not only accelerates the aging of the steel wire rope, but can also cause severe wear and tear, leading to the wire rope breaking or pulling through the slider, causing the lift assembly to fail and affecting the normal operation of the vehicle's doors and windows. Second, due to the elastic properties of the steel wire rope, the rapid lifting process may produce certain vibrations and noise, affecting riding or user comfort.

[0005] CN214943504U discloses a dual-track, rope-type window lifter for a vehicle and a vehicle. The dual-track, rope-type window lifter comprises a lifter body including a first and second cross-arranged cable; and a cable buckle disposed at the intersection of the first and second cables. The dual-track, rope-type window lifter for a vehicle utilizes a cable buckle disposed at the intersection of the first and second cables to limit the movement of the first and second cables, thereby reducing swaying of the first and second cables. This prevents the first and second cables from slapping against the door sheet metal and glass when the vehicle door is closed, generating unusual noise. Furthermore, the dual-track, rope-type window lifter prevents the guide rails of the vehicle from deflecting.

[0006] The dual-rail rope-type glass lifter in this patent not only avoids unnecessary contact between the cable and the door sheet metal and glass during movement and reduces noise by designing a cable clip, but also reduces the deflection of the guide rail by limiting the freedom of the cable, thereby ensuring the smoothness and reliability of the lifter operation. However, although the design of the cable clip is intended to reduce the shaking of the cable, it will bring some potential problems. First, the contact between the cable clip and the first and second cables may cause wear problems over time due to increased friction, which may affect the durability and functionality of the glass lifter. Secondly, each slider is connected to a cable at only a single point. This single-point fixing method may cause relative displacement and wear between the cable and the slider's fixing point after long-term repeated movement, thereby affecting the stability and reliability of the glass lifter.

[0007] In addition, on the one hand, due to differences in understanding among those skilled in the art; on the other hand, because the applicant studied a large number of documents and patents when making this utility model, but due to space limitations, not all details and contents are listed in detail. However, this does not mean that the utility model does not have the characteristics of these prior arts. On the contrary, the utility model already has all the characteristics of the prior art, and the applicant reserves the right to add relevant prior art to the background technology. Utility Model Content

[0008] In view of the shortcomings of the prior art, the present application proposes a cross-double-line fixed window lifter, which aims to solve one or more technical problems in the prior art.

[0009] Therefore, in response to the above technical problems, the present invention proposes a cross-double-line fixed glass lifter, including two columns arranged in parallel at intervals, two sliders slidably connected to the two columns, and a motor that provides driving force for the sliding of the sliders. One end of a first cable passing through the motor extends into the travel area of ​​the first slider along a first direction, and the other end extends into the travel area of ​​the second slider along a second direction opposite to the first direction. A second cable is connected between the first slider and the second slider, one end of the second cable extends into the travel area of ​​the first slider along the second direction, and the other end extends into the travel area of ​​the second slider along the first direction. The surface of the slider forms upper and lower channels that are staggered with each other in a manner with a height difference, so that the cable passing through the travel area can be detachably installed inside the slider.

[0010] The glass lifter of the present invention forms a cross-double-wire layout by placing two cables in two independent channels with a height difference inside the slider. This design effectively utilizes the space inside the slider, making the entire lifter structure more compact, reducing the external space occupied, and facilitating the realization of complex lifting functions in a limited space. The double-wire fixing method is more stable than the traditional single-point fixing method, and can avoid the wear and tear of the fixed point of the wire cable during long-term, high-frequency reciprocating motion. In addition, because the two cables are separated by a cross path inside the slider, direct contact between them after extending out of the slider is avoided. This design significantly reduces interference and friction between the cables, reduces noise and wear caused by friction, and improves the service life and smooth operation of the lifter.

[0011] According to a preferred embodiment, the upper and lower channels are formed by recessing at least a portion of the slider's surface. The lower channel has a greater recess depth than the upper channel. The upper and lower channels intersect at different heights, and both terminate at the same end surface of the slider, adjacent to the travel area. This design, by creating recessed areas of varying depths on the slider's surface to form the upper and lower channels, fully utilizes the slider's three-dimensional space, achieves physical isolation between the channels, and prevents interference between the cables during sliding.

[0012] According to a preferred embodiment, the columns include a first column with a first slider slidably connected thereto in parallel, and a second column with a second slider slidably connected thereto. The motor is located on the side of the first column away from the second column, or on the side of the second column away from the first column. By employing a parallel design of the first and second columns, this parallel structure provides stable support for the independent and parallel sliding of the sliders. Placing the motor on one side of the column prevents the motor from being affected by changes in column load, resulting in more stable motor drive.

[0013] According to a preferred embodiment, both ends of the first cable and the second cable are equipped with limit blocks whose geometric dimensions exceed their diameters, and the surface of the slider can form grooves at the beginning of the upper channel and the lower channel in a manner of expanding the recessed area, so that the limit blocks can limit the relative displacement between the cables and the slider by being inserted into the grooves. The limit blocks act as physical barriers, effectively limiting the lateral movement of the cables in the slider channel, preventing the cables from falling off or being misplaced due to factors such as vibration and impact, thereby improving the operational stability of the entire device. In addition, the limit blocks can also fit tightly against the inner wall of the groove under the drive of the motor and generate the necessary abutting force. This force transmission causes the slider to slide along the length direction of the column, thereby realizing the control and adjustment of the slider position.

[0014] According to a preferred embodiment, pulleys are provided near both ends of the first column, wherein the pulley located at the first direction end of the first column changes the extension direction of the second cable to the second direction end toward the second column; and the pulley located at the second direction end of the first column can change the extension direction of the first cable so that it passes through the motor. Pullies are provided near both ends of the second column, wherein the pulley located at the second direction end of the second column changes the extension direction of the second cable to the first direction end toward the second column; and the pulley located at the first direction end of the second column can change the extension direction of the first cable so that it passes through the motor. By configuring the pulleys, the cable can not only smoothly bypass the column or other obstacles to ensure the effective transmission of the driving force, but also adjust the path of the cable according to the actual installation environment and space limitations to accommodate different vehicle models and different window sizes.

[0015] According to a preferred embodiment, the slider is provided with smoothly transitioned chamfers at the ends of the upper and lower channels to guide the two staggered cables to extend in directions away from each other within the passage area after passing through the ends of the channels. The two cables are parallel to the length of the column on which the slider is located. The smoothly transitioned chamfers and orderly cable layout together enhance the reliability and stability of the device. By reducing friction and vibration, the risk of system failure caused by damage to mechanical components is reduced. At the same time, the orderly cable layout also helps ensure that the cables maintain the correct direction and position during movement, avoiding safety issues caused by cable misalignment or detachment.

[0016] According to a preferred embodiment, the contact surface of the stopper has the same inclination angle as the inner wall of the groove, and is provided with a plurality of concave and convex textures on the contact surface to prevent the stopper from slipping out of the top opening of the groove during cable movement. This design allows the stopper to fit more closely to the inner wall of the groove when inserted into the groove. When the cable is subjected to tension or vibration, the close fit between the stopper and the groove reduces relative movement between the two, thereby enhancing the fixing effect of the stopper in the groove.

[0017] According to a preferred embodiment, the inner dimensions of the groove are configured to be larger than the stop block to leave excess space. This excess space effectively absorbs slight elongation of the cable due to aging, thus preventing interference with the rest of the window lifter structure and extending the service life of the device.

[0018] According to a preferred embodiment, the window lifter is equipped with a bracket for mounting the column and motor. As a basic supporting member, the bracket not only provides support and fixation for the column, motor, and pulley, but also allows for a secure connection to the internal structure of the vehicle door through multiple mounting holes on its surface, thereby improving the stability of the window lifter.

DETAILED DESCRIPTION

[0031] The present invention will be described in detail below with reference to the accompanying drawings.

[0032] Example 1

[0033] The utility model relates to a cross-double-line fixed glass lifter, such as Figure 1 As shown, it mainly includes a column 200 and sliders 101, 102 slidably connected to the column 200. The function of the sliders 101, 102 is to support the window glass so that the glass can slide up and down along the column 200 as the sliders 101, 102 to achieve the lifting function. The column 200 is installed inside the vehicle door through a bracket 600. The bracket 600 serves as a basic supporting component. Its design is usually flat and is fixedly connected to the internal structure of the door through multiple mounting holes provided on its surface. A motor 400 is also integrated on the bracket 600. The motor 400 is responsible for providing the necessary driving force for the sliding of the sliders 101, 102. The motor 400 is designed to have a first cable 301 running through its interior, and its middle section is connected to the output shaft of the rotor of the motor 400. The motor 400 applies opposite pulling forces to the first cable 301 by rotating the rotor forward and reverse, thereby enabling the sliders 101 and 102 connected to both ends of the first cable 301 to slide smoothly on the column 200 along the first direction or the second direction.

[0034] Preferably, if Figure 1 As shown, a first column 201 and a second column 202 are arranged in parallel and opposed relation on the support structure 600. They are fixed to the two side edges of the support 600, respectively, to achieve balanced and symmetrical support for the vehicle window glass. Each column 200 is equipped with a slider 101, 102. For the convenience of subsequent description, the first column 201 is slidably connected to the first slider 101, and the second column 202 is slidably connected to the second slider 102. The two sliders 101, 102 can move synchronously under the drive of the motor 400 to drive the vehicle window glass supported by them to complete the lifting operation.

[0035] Preferably, if Figure 2 As shown, a double-layer staggered channel structure is introduced on the surfaces of the first and second sliders 101, 102. Specifically, each slider 101, 102 is constructed with two layers of channels: the upper channel 110 is designed to be shallower, while the lower channel 120 is deeper. This differentiated design creates a distinct height gradient on the surfaces of the sliders 101, 102, resulting in an interlaced layout of the upper and lower channels 110, 120 in three-dimensional space.

[0036] Preferably, if Figures 3 to 5As shown, due to the different depths of the upper channel 110 and the lower channel 120, their intersections on the sides of the sliders 101 and 102 are staggered and formed at different heights. Furthermore, the upper channel 110 and the lower channel 120 begin at the interior of the sliders 101 and 102, while their ends converge at the same end edge of the sliders 101 and 102. These ends connect to a passage area 140 outside of this end face of the sliders 101 and 102. This design facilitates the subsequent assembly of the cables 301 and 302. The passage area 140 is parallel to the end faces of the upper channel 110 and the lower channel 120, and is the open space through which the cables 301 and 302 traveling in the first or second direction must pass when connecting with the sliders 101 and 102.

[0037] Preferably, if Figure 1 As shown, each slider 101, 102 is connected to two cables 301, 302 extending in opposite directions. These cables 301, 302 can be moved by a motor 400, thereby pulling the slider 101, 102 to slide smoothly along the column 200. To ensure the smooth operation and durability of the cables 301, 302, each slider 101, 102 is equipped with an upper channel 110 and a lower channel 120 for accommodating the corresponding cables 301, 302. This layout effectively separates the cables 301, 302 extending in opposite directions, preventing them from contacting each other during the movement of the sliders 101, 102. This avoids wear caused by unnecessary relative movement between the cables 301, 302 and reduces the maintenance burden of the window lifter of the present invention.

[0038] Preferably, if Figure 1As shown, the first and second sliders 101, 102 are connected via two cables 301, 302, each of which performs a specific function. Specifically, both ends of the first cable 301 and the second cable 302 are connected to the first and second sliders 101, 102, respectively. The difference is that the first cable 301 is connected to the motor 400, allowing it to "actively" apply the tension required for sliding the sliders 101, 102 under the drive of the motor 400. The second cable 302, on the other hand, is used to connect the first and second sliders 101, 102, and "passively" transmit the tension between the two sliders 101, 102, thereby enabling the two sliders 101, 102 to slide to the same degree. Particularly preferably, one end of the first cable 301 is connected to the beginning of one of the channels of the first slider 101 via the passage area 140 of the first slider along a first direction; the other end of the first cable 301 is connected to the beginning of one of the channels of the second slider 102 via the passage area 140 of the second slider along a second direction. In other words, the two ends of the first cable 301 are connected to the channels of the respective sliders 101 and 102 in opposite directions. With this design, the rotation direction of the motor 400 can control the movement of the sliders 101 and 102 in different directions. When the rotor of the motor 400 rotates in the forward direction, the first cable 301 connected to one of the sliders 101 and 102 is tensioned, and the resulting tension drives the slider 101 and 102 to slide upward (in the first direction) along the column 200. Conversely, when the rotor of the motor 400 rotates in the reverse direction, the other first cable 301 is tensioned, correspondingly driving the other slider 101 and 102 to slide downward (in the second direction). This mechanism ensures that no matter how the rotation direction of the motor 400 changes, the two sliders 101 and 102 can achieve smooth and bidirectional sliding on the column 200.

[0039] Preferably, if Figure 2As shown, the widths of the upper channel 110 and the lower channel 120 are designed to match the diameters of the cables 301, 302, ensuring that the cables 301, 302 can be securely embedded and pass through the two channels, achieving smooth and unobstructed assembly. The surfaces of the sliders 101, 102 can be expanded to form grooves 130 at the beginning of the channels. These grooves 130 provide a secure anchor point for the connection between the cables 301, 302 and the sliders 101, 102. Particularly preferably, both ends of the first and second cables 301, 302 are equipped with limit blocks 310. The geometric dimensions of these limit blocks 310 are designed to be larger than the diameters of the cables 301, 302. These limit blocks 310 can be embedded in the grooves 130 formed on the surfaces of the sliders 101, 102, effectively limiting the relative movement between the cables 301, 302 and the sliders 101, 102 through physical contact, thereby establishing a secure mechanical connection. Driven by motor 400, the contact surfaces of the stoppers 310 of the first and second cables 301, 302 tightly contact the inner wall of groove 130, generating the necessary contact force. This force transmission causes the sliders 101, 102 to slide along the length of the column 200, enabling control and adjustment of the positions of the sliders 101, 102. The interaction between the cables 301, 302, the stoppers 310, and the groove 130 ensures stable and efficient power transmission between the various components of the window lifter, enabling smooth movement of the sliders 101, 102 along a designated path.

[0040] Preferably, if Figure 2 As shown, the grooves 130 of the sliders 101 and 102 are designed with ample internal space, exceeding the dimensions of the stopper 310. This design allows for sufficient clearance after the stopper 310 is assembled. This margin is designed to anticipate the natural elongation of the cables 301 and 302 due to material aging during long-term use. When the cables 301 and 302 undergo slight elongation, this margin effectively accommodates this change, preventing interference with the remaining components of the window lifter and extending the service life of the device. Although the stopper 310 at the end of the cables 301 and 302 may lose its ability to maintain close contact with the sidewalls of the groove 130 due to elongation, even in this situation, the present design allows the drive force of the motor 400 to quickly adjust the position of the stopper 310, urging it to engage the sidewalls of the groove 130 and ensure continuous and stable power transmission. This mechanism ensures that the window lifter can maintain normal functional operation during the control process, although there may be a slight response delay, thereby avoiding performance failure caused by the elongation of the cables 301 and 302.

[0041] Preferably, if Figure 1 、 Figure 2As shown, to ensure that the direction of the driving force applied by the motor 400 to the sliders 101, 102 via the cables 301, 302 is consistent with the predetermined sliding direction of the sliders 101, 102, the sliders 101, 102 are integrated with smoothly transitioning chamfers at the end positions of the upper channel 110 and the lower channel 120. These chamfers guide the two staggered cables 301, 302, allowing them to naturally extend in opposite directions after passing through the ends of the upper channel 110 and the lower channel 120. This design ensures that the extension path of the cables 301, 302 remains parallel to the length of the column 200 to which the sliders 101, 102 are attached, thereby accurately transmitting the driving force and achieving efficient and stable sliding of the sliders 101, 102.

[0042] Preferably, the stopper 310 is designed so that its contact surface and the inner wall of the groove 130 share a consistent inclination angle. Specifically, the inclination angle is designed so that the angles between the contact surface of the stopper 310 and the bottom surface, as well as between the inner wall of the groove 130 and the bottom surface, match and are equal. This design allows the bottom tip of the stopper 310 to gradually penetrate deeper along the inclined inner wall of the groove 130 until it is fully seated, thereby achieving a tight fit between the two. This design not only simplifies the installation process but also ensures that the stopper 310 can be accurately positioned in the predetermined position of the groove 130, avoiding functional failure due to positional deviation. In addition, the inclination angle plays a key role in preventing the stopper 310 from slipping. Because the top of the groove 130 is open, the stopper 310 may tend to slide upward along the inner wall of the groove 130 when subjected to external forces such as tension from the cables 301, 302 or vibration. However, the presence of the tilt angle means that when the stopper 310 attempts to slide upward, it encounters gradually increasing resistance. This is because as the stopper 310 rises, the contact force between its contact surface and the inner wall of the groove 130 gradually increases, and the friction force also increases accordingly. This self-locking effect effectively limits the upward movement of the stopper 310, thereby preventing it from sliding out of the top opening of the groove 130.

[0043] Preferably, to enhance anti-slip performance, the contact surface of the stopper 310 is provided with a series of strip-shaped concave and convex textures. These textures are preferably arranged in a parallel pattern, running parallel to the top or bottom surface of the stopper 310. This design increases the friction coefficient of the contact interface, effectively suppressing the potential slippage of the stopper 310 along the top opening edge of the groove 130, even when dynamic components such as the cables 301 and 302 are experiencing high-speed motion or high-intensity tension.

[0044] Preferably, if Figure 1As shown, the glass lifter designed in the present invention integrates multiple pulleys 500, which are placed at the ends of both sides of the column 200. The main function of the pulley 500 is to guide the first cable 301 and the second cable 302 to move around it, so as to achieve flexible adjustment of the driving force transmission direction. Specifically, Figure 1 As shown, the pulley 500 located at the lower end (second direction) of the first column 201 and the pulley 500 located at the upper end (first direction) of the second column 202 correspond to each other in terms of function. They work together to enable the first cable 301 connected to the first slider 101 and the second slider 102 to change its direction of travel, ensuring that it can pass through the motor 400 located on one side of the first column 201. Similarly, the pulley 500 at the upper end of the first column 201 and the pulley 500 at the lower end of the second column 202 also play a similar role. They are responsible for changing the travel path of the second cable 302, ensuring that the two ends of the second cable 302 have opposite extension directions at the first slider 101 and the second slider 102.

[0045] In the operational process, such as Figure 1 As shown, the motor 400 serves as a power source, and its output directly acts on the end of the first cable 301 connected to the first slider 101. When the motor 400 drives the first cable 301 to move in the second direction, the tension carried by the first cable 301 is transmitted to the limit block 310 embedded in the groove 130 of the first slider 101, thereby causing the limit block 310 and the first slider 101 to form a tight synchronous motion, and move together toward the bottom of the first column 201. Conversely, if the motor 400 changes the driving direction and instead drives the end of the first cable 301 connected to the second slider 102 to move in the first direction, the tension of the first cable 301 will also act on the limit block 310 located in the groove 130 of the second slider 102, driving it to closely cooperate with the second slider 102 and move synchronously toward the top of the second column 202. At the same time, when the motor 400 drives either slider 101 or 102 to move, the second cable 302 can serve as a transmission element, effectively distributing the driving force to the slider 101 or 102 not directly driven by the motor 400, ensuring that the two sliders 101 or 102 maintain synchronized motion. In summary, this configuration of the pulley 500 optimizes the spatial layout of the cables 301 or 302 within the bracket 600, effectively reducing the possibility of entanglement and interference, while ensuring the smoothness and efficiency of the sliders 101 or 102 during the lifting process.

[0046] Example 2

[0047] This embodiment is a further improvement of the above embodiment, and repeated contents will not be repeated here.

[0048] Definition of direction: combined Figure 6The length direction of the column 200 is the slider movement direction X. The slider width direction Y is perpendicular to the slider movement direction X. The slider thickness direction Z is perpendicular to the slider movement direction X and the slider width direction.

[0049] The utility model relates to a slider for a glass lifter, such as Figure 6 As shown, it comprises a main body 100 having a bow 103 for slidably engaging with a column 200, a cable holder 104 for holding two cables 301, 302, and a sliding shoe 105 for holding the main body 100 against the column.

[0050] Preferably, if Figures 6 to 9 As shown, the bow 103 has a curved portion on one side of the column 200 that is shaped to fit the side wall of the column 200, so that the main body 100 can translate along the longitudinal direction of the column 200. The curved portion bends toward the column 200 in the thickness direction Z of the slider, or may also act on the side of the column 200 away from the slider (i.e., the side facing the slider) with the help of an elbow. Figure 1 dorsal side of the ).

[0051] Preferably, if Figures 6 to 9 As shown, the sliding shoe 105 is located on the other side opposite to the bow 103 in the slider width direction Y, so that the bow 103 is connected to the cable holder 104 in the slider width direction Y, and the sliding shoe 105 is also connected to the cable holder 104 on the other side. The sliding shoe 105 may also have a form-fitting member on the side away from the cable holder 104 for mechanically retaining it on the side of the column 200 facing the main body 100, or preferably retaining it on the column 200 in a form-fitting manner, for example, it can also be slidably buckled on the column 200 in an elbow manner.

[0052] Preferably, if Figures 6 to 9 As shown, the slider body 100 is provided with a cable retainer 104 approximately centered in the slider width direction Y. This cable retainer 104 comprises an upper channel 110 and a lower channel 120, retaining the longitudinal front regions of two cables 301 and 302 within the upper and lower channels 110 and 120, respectively. The longitudinal front region of the first cable 301 terminates in a cable end 310a, while the longitudinal front region of the second cable 302 terminates in a cable end 310b. These end 310b are formed as protrusions with a larger diameter than the cables, such as nuts or bearing balls integrally formed with the cables. The cable end 310b is retained in a groove 130 formed at the distal end of the lower channel 120, capable of withstanding the tension of the window lift along the cable's length. The groove 130 has a shape that matches the protrusion and provides clearance for fluctuations in the lifting motion, particularly along the pulling direction, which also serves as an elongation compensation gap.

[0053] like Figures 6 to 9 As shown, the second cable 302 extends from the cable end 310b, which is restrained by the groove 130, along the lower channel 120 of the slider body 100, which has a diameter similar to that of the cable, to the predetermined cable intersection 200 of the cable retainer 104. The cable intersection 200 is formed by four intersecting through-slots of the slider body 100. These four through-slots intersect with each other, particularly in a generally X-shaped intersection. Within this X-shaped intersection, one of the through-slots is formed by the lower channel 120. After passing through the intersection point within the X-shaped intersection, the lower channel 120 enters another through-slot 601 within the X-shaped intersection. Thus, the second cable 302, extending from the cable end 310b away from the slider body 100 (e.g., toward the motor 400), exits the lower channel 120, passes through the intersection point within the X-shaped intersection, and enters another through-slot 601 having a diameter substantially similar to that of the cable.

[0054] like Figures 6 to 9 As shown, the X-shaped intersection area of ​​the slider body 100 is defined in the slider width direction Y by a plurality of triangular bosses 400a, 400b, and 400c within the cable retainer 104. Triangular boss 400b is defined by the lower channel 120 and the through-slot 602 for guiding the first cable 301. A first triangular side 401b of triangular boss 400b is formed by the sidewall of the lower channel 120, while a second triangular side 402b of triangular boss 400b is formed by the sidewall of the through-slot 602 for guiding the first cable 301. A third triangular side of triangular boss 400b is defined by a first sidewall 605b of the slider body 100 in the slider motion direction X. In the slider movement direction X, another triangular boss 400a opposite to the triangular boss 400b across the X-shaped intersection area is also constructed in a similar manner, that is, the three triangular sides of the triangular boss 400a are respectively composed of the side walls of the upper channel 110, the side walls of the through groove 601 and the second side wall 605a of the slider movement direction X of the slider body 100.

[0055] like Figures 6 to 9 As shown, the triangular boss 400 c formed by the X-shaped intersection is defined by the side walls of the lower channel 120 for guiding the second cable 302 and the upper channel 110 for guiding the first cable 301 .

[0056] The X-shaped intersection is formed because the "through groove 601 and lower channel 120, which jointly guide the passage of the second cable 302," and the "through groove 602 and upper channel 110, which jointly guide the passage of the first cable 301," intersect at an intersecting angle within the cable retainer 104. It is conceivable that the channels or grooves forming the X-shaped intersection are formed by open recesses recessed inward from the surface of the cable retainer 104, thereby creating an accessible operating area for cable replacement. It is also conceivable that the channels or grooves forming the X-shaped intersection can be formed, at least partially, as through holes below the surface of the cable retainer 104 (i.e., within the body 100).

[0057] like Figures 6 to 9 As shown, the upper channel 110 and the lower channel 120, each used to guide two different cables, form two paths at different heights in the slider thickness direction Z. In other words, the bottom of the upper channel 110 differs from the bottom of the lower channel 120, forming a step 800 at least within the X-shaped intersection. The step 800 includes two treads arranged at different heights and a riser located between the two treads to create a height difference and maintain an orthogonal connection between the two treads. The higher tread in the slider thickness direction Z is formed by the bottom surface of the upper channel 110, the lower tread is formed by the bottom surface of the through-channel 601, and the riser is formed by the sidewall of the through-channel 601. Because the step 800 has a thickness in the slider thickness direction Z that is roughly equivalent to the cable diameter (i.e., the height of the riser), the second cable 302 can pass over the first cable 301 in the slider thickness direction Z within the X-shaped intersection. When the slider moves up and down under the action of the two cables, for example, directly or indirectly driving the window glass to move, the cables in the X-shaped intersection area will bear the tension along the movement direction X of the slider.

[0058] according to Figures 6 to 9The effect of the pulling force will be explained below in conjunction with the through-channel 601 and the lower channel 120 that jointly guide the second cable 302. The pulling force is borne by the groove 130 at the cable end 310b and acts along the cable in the upper channel 110 on the first triangular side 401b of the triangular boss 400b and the load-bearing wall 401c of the triangular boss 400c opposite thereto. The "through-channel 601 and the lower channel 120 that jointly guide the second cable 302" and the "through-channel 602 and the upper channel 110 that jointly guide the first cable 301" extend at approximately the same angle relative to the length direction of the column 200. Preferably, an obtuse angle is defined between the lower channel 120 and the upper channel 110, while an acute angle complementary to the obtuse angle is defined between the upper channel 110 and the through-channel 601. The obtuse angle makes the component of the pulling force acting on the load-bearing wall 401c greater than the component of the pulling force acting on the first triangular side 401b of the acute-angled triangular boss 400b opposite to the load-bearing wall 401c, especially several times greater than the component of the pulling force acting on the first triangular side 401b of the acute-angled triangular boss 400b opposite to the load-bearing wall 401c.
