Description

Window Regulator Cable Assemblies

technical field

The utility model relates to a window adjuster cable assembly, in particular to a window adjuster cable assembly for vehicles.

Background technique

Vehicle doors are generally fitted with window glass, and the window glass can be lowered to an open position or raised to a closed position. The raising and lowering of the window glass is controlled by a window regulator. Commonly used window regulators include gear-type window regulators and cable-type window regulators.

A general gear-type window adjuster includes a gear-shaped part with an arm and a small planetary gear meshed with the gear-shaped part, wherein the arm of the gear-shaped part is mounted on the window glass and driven by the rotation of the small planetary gear The gear part, and then controls the window lift.

The cable device in a general cable-type window regulator is coiled on a cable shaft or a drum, and a rotating arm is further connected to the cable shaft, and the rotation of the cable shaft can cause the lifting of the rotating arm. The pivoting arm is connected directly or indirectly to the lower edge of the window glass. Therefore, the lifting of the corresponding window glass can be controlled by the lifting of the rotating arm.

Please refer to FIG. 1 and FIG. 2 , which are schematic diagrams of a conventional single-acting cable device. In addition, various types of double-acting cable devices have also been widely used.

Regardless of whether the single-acting or double-acting cable devices are divided into two categories, that is, unshielded cable devices and shielded cable devices.

As shown in FIG. 1 , it is a cable combination 10 of a single-acting unshielded cable window regulator. The upper pulley 20 is pivotably mounted on a rigid member 24 via a pivot shaft 22 . The lower pulley 26 and the drum 30 are also pivotably mounted on the rigid member 24 via the pivot shaft 28 and the drum shaft 32 respectively. The cable arrangement 34 is coiled around the upper pulley 20 , the lower pulley 26 and the drum 30 to form the cable arrangements 36 , 38 and 40 . The cable routing 40 is provided with a swivel arm 42 attached directly or indirectly to the bottom of the window glass (not shown) and thereby divided into a cable routing 40A between the upper pulley 20 and the swivel arm 42 and a lower pulley 26 The cable routing 40B between the rotating arm 42 has two parts.

Clockwise rotation of the drum 30 causes the pivot arm 42 to lower, and counterclockwise rotation causes the pivot arm 42 to rise.

A typical cable arrangement includes two separate lengths of cable 34A and 34B. Wherein one end of cable 34A is connected on the rotating arm 42, and the other end is arranged on the drum 30, and its end near the drum 30 is generally coiled several times on the drum to allow lifting or lowering the rotating arm 42. Similarly, one end of the cable 34B is connected to the swivel arm 42 and the other end is set on the drum 30 , and its end adjacent to the drum 30 is also coiled several times on the drum 30 to allow the swivel arm 42 to be lifted or lowered. For example, cable 34A can be used as a lift cable, which raises the window glass in a tensioned state, and cable 34B can be used as a lower cable, which lowers the window glass when tensioned.

After each component shown in Figure 1 is assembled into a subassembly, it is further installed on the car door. Its installation method can be to use screws, bolts, rivets and other similar fixing parts to pass through the fixing holes 44 on the subassembly and the corresponding on the door. The fixing holes are fixed. Then, install the window glass.

The upper pulley 20 and the lower pulley 26 are each provided with a circumferential groove at the cable position. The outer surface of the drum 30 has a spiral groove, so that when the window glass is raised, the cable 34A is wound in the spiral groove and the cable 34B is loosened from the spiral groove; Unwind and the cable 34A winds in the helical groove.

When the components shown in FIG. 1 are combined into subassemblies, it is particularly important to keep the cables from falling off from the wheel bodies. Therefore, the pivoting shaft of the pulley must be firmly fixed at a specific position, and generally the rigid member 24 is made of a steel sheet stamped from a 0.6 mm thick steel plate. The subassembly in Fig. 1 is assembled on the car door by means of the fixing holes 44 thereon. Due to the rigidity of the door, the pivot shafts of each wheel body are actually kept on the rigid element 24 with a fixed distance interval. Therefore, the rigid element 24 A certain area of (the hatched area at A as shown in the figure) becomes redundant.

As shown in FIG. 2 , it is a cable combination 111 of a single-acting shaded cable window regulator. The functions realized by its various components are the same as those of the corresponding components in the window regulator cable assembly 10 in FIG. 1 . In this case, instead of the above-mentioned T-shaped rigid element 24, the upper pivot shaft 122 and the lower pivot shaft 128 are fixed by the rigid element 150, thereby ensuring that the upper pulley 120 and the lower pulley 126 are installed in a fixed-distance relationship.

A separate plate 152 is provided at the drum 130 . In this state of implementation, the cables are thus held in the associated grooves and the cable routing 136 , 138 is provided with a cable sheath 154 .

The cable sheath 154 has elastic deformation capability, and it is a tube body formed by tightly helically coiled metal strips, and a friction-reducing material, such as polytetrafluoroethylene (PTFE), is provided inside the tube body, and the outside of the tube body A waterproof material, such as a plastic material, is provided. Two ends of the cable sheath 154 are respectively matched with the connector 156 and the board 152 on the rigid element 150 . In particular, the joints must be strong enough to withstand a load equivalent to the maximum tensile load of the cable (since the joint 156 reacts to this load). Further, a tensile load applied to the cable will act an equivalent compressive load (neglecting friction) on the shielded cable. Therefore, the shielded cable must also be strong enough to withstand a load equivalent to the maximum tensile load of the cable. Based on the above reasons, the tightly helically coiled metal strip needs to be made extremely finely, and in addition, an inner bushing and an outer waterproof material for reducing friction are required on it, so the cost is relatively high.

The elastic deformation capability of the cable sheath 154 is preferably such that both ends of the sheath can move relative to each other. By bending the cable sheath 154 into a U shape, both ends thereof are brought closer to each other, and by straightening the cable sheath 154, both ends thereof are separated from each other. Therefore, the linear distance between its two ends can be changed. In some mounting configurations, the changes described above may be used to move the plate 152 closer to the rigid member 150 to avoid obstructions when assembling the window regulator cable assembly 111 to its corresponding door. When the obstruction is removed, the plate 152 and rigid member 150 are returned to their proper positions, and the window regulator cable assembly 111 is mounted to the door. Thus, the use of shielded cables may assist in installing the window regulator cable assembly to the door and secure the cables within their associated pulley channels.

As noted above, excess material is used in the existing window regulator cable assembly 10 shown in FIG. 1, and the existing window regulator cable assembly 111 shown in FIG. The rigid element 150 and the plate body 152 are provided with interfaces of corresponding strength, and the cost is relatively high.

For the shaded window regulator cable combination, further reference may be made to US Patent No. 5,694,717, European Patent Nos. 0107531, 0385167, and 0607589, and British Patent No. 1,448,795. European Patent No. 0107531, No. 0607589, U.S. Patent No. 5694717 and British Patent No. 1448795 all disclose a system for internal tensioning of the cable. The action tensions the cable internally. The tensile load of the cable is equal to the compressive load of the spring and the same as the compressive load of the cable jacket.

Detailed ways

FIG. 3 shows a window adjustment cable assembly 212 of the present invention, wherein components performing the same functions as those shown in FIG. 1 are identified with numbers greater than 200. As shown in FIG. It can be seen that the upper and lower wheels 220 , 226 are mounted on a rigid member 250 which is smaller than the rigid member 150 in FIG. 2 .

Similarly, the cable drum 230 is mounted on a separate plate 252 which is smaller than the separate plate 152 in FIG. 2 .

FIG. 3 also shows (schematically) that the rigid element 250 and the separate plate 252 are secured to the rigid frame (in this case the door 270 ) via corresponding fastening holes 244 . Once the cable assembly 212 is secured to the door 270 , the rigidity of the door ensures that the rigid member 250 is maintained in its exact position away from the separate panel 252 .

The cable routing 236 is surrounded by a semi-rigid tube 260 . In this case the semi-rigid tube 260 is made of extruded plastic material, such as PVC (polyvinyl chloride) or polyethylene. Tube 260 has an elongated slit 262 (FIG. 6). Semi-rigid tube 261 is the same as tube 260 .

The diameter of the inside of the tube 260 loosely fits the cable 234 . The diameter of the tube 260 at this time is 4 mm.

The outer diameter of the tube is 6mm.

The end of the tube 260 abuts against the fitting 266 .

Tubes 260, 261 temporarily exit drum 230 from upper and lower wheels 220, 226, respectively. Thus, the cable assembly 212 can be manufactured, for example, with all of the components shown in FIG. 3 (except the door 270 ) as a subassembly. This subassembly can be transported and secured to the door 270 and the tubes 260, 261 will ensure that the cables cannot come out of either cable channel on either wheel.

Once the subassembly is secured to the door 270, the tubes 260, 261 become redundant as the rigid member 250 is held in place away from the panel 252 to take advantage of the rigidity of the door.

By comparing and comparing Figures 1-3, the following points can be noticed:

a) All three Figures show an embodiment providing a subassembly to ensure that the wire is under tension and does not come loose from the drum or pulley prior to installation on a door or similar;

b) the excess material indicated by hatching at A in Fig. 1 is absent in Fig. 3, thus allowing the embodiment of Fig. 3 to be lighter than that of Fig. 1;

c) The expensive arcuate sheath shown in Fig. 2 is absent in Fig. 3. The pipe cost in Fig. 3 is cheap;

d) The joint 156 in Figure 2 needs to be strong enough to resist full cable tension loading. The joint 266 of FIG. 3 only needs to be strong enough to "transfer" loads prior to assembly of the cable assembly to the door, which loads are significantly lower than the "in-use" loads of installing the cable assembly on the door and the associated vehicle in use. .

As mentioned above, the tubes 260 , 261 each have an elongated slit 262 . This allows the tubes 260, 261 to be removed from their associated cabling once the subassembly is installed on the door. In addition, depending on the assembly method employed, the slits may facilitate assembly of the tubes to the cable routing during fabrication of the subassembly prior to delivery.

However, in other embodiments the slot may not be required as the tube may remain on the associated cable routing in use. It will be appreciated that since no tubes are required to obtain tension in the cable arrangement, tubes are clearly superfluous in this case (except when two cable paths cross and bends are used, see below). In order to reduce costs, it is preferable to ensure that the tubes are manufactured only from extruded plastic materials.

Thus, it will be appreciated that the semi-rigid tubes 260, 261 cope with the aforementioned "transferring" loads in the longitudinal direction. In a more specific embodiment, such a tube may also be semi-rigid in the lateral direction. This results in the ends of the tubes being kept at the same distance from each other, unlike the ends of the arcuate tubes in the previous case.

Shown in FIG. 4 is a double acting lift cable assembly 313 , the components of which perform substantially the same function as cable assembly 10 and are numbered greater than 300 .

In this case there are two laterally separated rigid elements 350,351. The rigid member 351 includes a second upper pulley 321 and a second lower pulley 327 .

Cable routing 390 includes cable routing 391 from pulley 320 to deflector 342A and cable routing 392 from deflector 342A to pulley 326 . The cable routing 394 includes a cable routing 395 from the defibrator 342B to the pulley 321 and a cable routing 396 from the defibrator 342B to the pulley 327 .

In this case the cable arrangement consists of three cables 397 , 398 , 399 , cable 397 being similar to cable 234A in that cable 397 is connected at one end to needle deflector 342A and at the other end to cable drum 330 . Cable 397 is thus a lifting cable. Cable 398 is similar to cable 234B in that it is connected to needle deflector 342B at one end and to cable drum 330 at the other end. Cable 398 is thus a lowering cable.

It will be appreciated that the cable 399 is connected to the deflector 342B at one end and to the deflector 342A at the other end. This cable is an intermediate cable and acts in the raising direction by raising the deflector 342B, but can also act in the lowering direction by lowering the deflector 342A.

In this case there are three cable runs 372 , 373 , 374 comprising semi-rigid tubes 375 , 376 , 377 .

It can be seen that since the cable runs 372 and 376 intersect at point C, any contact between all these cable runs is prevented by the semi-rigid 375,376.

Therefore, once assembled to the door, all three semi-rigid tubes can be removed in order to reuse them, while also reducing the weight of the assembly. However, the tubes are very cheap and also very light, so it's okay to leave them on the assembly as well. More specifically, when there are two cables crossing, it is preferable to leave at least one semi-rigid tube to ensure that the cable runs do not touch each other, nor can they be "sawed" when operating the adjuster in use. Action disrupts cable routing.

FIG. 5 shows another embodiment of a double acting lift window regulator cable assembly 414 in which the component switch performs substantially the same function as the components of the cable assembly 313 , which are numbered 100 above. In this case, the plate on which the cable drum 430 is mounted is incorporated in the rigid element 451 . Because of this cable arrangement, the lower pulleys 427, 426 each comprise a pair of wheels that rotate in opposite directions. At this point, semi-rigid tubes 482, 483 are provided on the cable routing 480, 481.

In other embodiments, certain end fittings may be dispensed. Thus, for example, the end fittings 266 of the plate body 252 can be omitted. In this case, the tubes 260 , 261 may be elongated to come into contact with the cable drum 230 . Once assembled to the door, the semi-rigid tube can be removed to allow the cable drum 230 to rotate freely.

It will be appreciated that the cable routings 236, 238, 372, 373, 374, 480, 481 may be straight and the tubes correspondingly straight. In other embodiments, the semi-rigid tube may be crimped or bent, particularly for crimped connections to window glass. Thus, a coiled semi-rigid tube may be provided, with associated cable routing requiring a bend or twist to avoid components inside the door. Once assembled, the crimped tube can rest against and be laterally supported by a particular component. The cable tensioning system tends to straighten the cable thereby tensioning the cable against the concrete part, but the tube acts between the cable and the concrete part to prevent sawing movement of the cable over the part. It will be appreciated that in this case, once installed in the door, the tube need not bear any longitudinal loads, merely acting as a plane on which the cables slide.

As a result of wear and stretching of the cable in use, it is sometimes necessary to include a cable tensioning system. Typically the tensioning system can act to displace part of the cable run, thus increasing the active length of the cable run, or alternatively Ground, a tensioning system to shorten the active length of the cable.

Referring to Fig. 7, there is shown a cable tensioning system applied with the present invention. The needle deflector 510 is mounted to slide on the guide rail 512 . The window glass 514 is installed on the needle deflector through a fixing piece (not shown). The cable 516 has one end 516A fixed to the needle deflector 510 . A pulley 518 is provided. A displacer in the form of a lug 520 that pivots at pivot point A is also provided. The lug 520 includes an arcuate guide slot 522 in which the cable 516 slides when the glass is raised or lowered. The lug 520 is biased in a clockwise direction by a spring (not shown) as indicated by arrow B. As shown in FIG. Pulley 518 pivots at pivot point A and can rotate independently of lug 520 . A biasing spring maintains tension in the cable 516 . As the system wears, the lugs can be turned slightly in a clockwise direction to counteract the wear.

It will be appreciated that arcuate guide slot 522 laterally displaces portions of cable 516 (with region 516A being displaced laterally in the direction of arrow C), thus causing the length of the cable path to increase.

In other embodiments, as shown in FIGS. 3 , 4 or 5 , the lug 520 may be associated with either a pulley or a drum. In other embodiments, the displacer may operate partially along the cable run to displace part of the cable laterally. In other embodiments, the pivoting of the pulley, or the pivoting of the cable drum may be biased so as to move the overall wheel replacement when worn to obtain tension in the cable. In these cases, the area where the cable contacts the wheel needs to be laterally biased.

FIG. 8 is a detailed diagram of the needle deflector 242 (see FIG. 3 for a schematic diagram). At this moment, the needle deflector is guided on the guide rail 630 .

The lift cable 234A includes an end 632 that includes a cable gland 634 . End portion 632 and nipple 634 are positioned within housing portion 636 of needle deflector 242 . There is also a spring 638 within the housing. The spring 638 is a helically wound compression spring and the function of the spring is to bias the fitting 634 downwardly relative to the housing portion 636 . In this way, the tensioning system can effectively shorten the length of the lift cable 234A.

The lowering cable 234B also includes an end portion 662 that includes a cable nipple 664 that is biased upward by a spring 668 to shorten the length of the lowering cable 234B.

It will be appreciated that in other embodiments the system is used to "shorten" the cable and need not be included in the deflector.

It can also be understood that the needle deflector shown in FIG. 8 can be used as the needle deflector 342A in FIG. 4 . In this case, spring 638 may provide a tensioning system for lift cable 397 and spring 668 may provide a tensioning system for transition cable 399 . It can also be understood that the needle deflector of FIG. 8 can also be used as the needle deflector 342B of FIG. 4 . In this case, spring 638 may act as a tensioning system for transition cable 399 and spring 668 may act as a tensioning system for lowering cable 398 .

It is preferred to have a tensioning system for raising the cable, a single acting tensioning system for lowering the cable, and a single acting tensioning system for the transition cable (if present in the particular system). By using the needle deflector shown in FIG. 8 instead of the needle deflectors 342A, 342B in FIG. 4 , a tensioning system that can lift cables, lower cables and transition cables can be provided. It is also understood that such a system provides a tension spring at either end of the transition cable 399 . In another embodiment, one of the typical springs acting on the transition cable can be omitted to save cost.

All the embodiments described so far relate to vertically opening windows. However, the invention can also be applied to closures that open horizontally. The terms "upper" and "lower" in the claims should therefore not be construed as limiting the specific position of each wheel relative to the other wheels in the claims.
