Description
Technical Field
[0001] The utility model relates to the technical field of lifters, in particular to a wire harness installation structure of a glass lifter and a glass lifter. Background Art
[0002] With the development of the automobile industry, the technological sense of automobiles has gradually increased. Among them, the multifunctional technology of car window glass (such as zoned color change, heating, video playback, etc.) has also gradually been adopted by OEMs; to achieve the above functions, it is necessary to electrically connect the glass to the power supply equipment through a wiring harness.
[0003] In the prior art, most of the two ends of the harness are connected to the photochromic glass and the car power supply respectively. In order to meet the design requirements, the length of the harness must be greater than the lifting stroke of the glass, resulting in a relatively loose harness. In addition, the harness is made of several strands of wires that are twisted and wound, and the shape of the harness is usually crooked. As a result, when the car is driving (for example, uphill / downhill or in poor road conditions), when the door is opened or closed, or when one end of the harness is raised or lowered with the glass, the harness shakes greatly, causing the harness to easily collide with the door substrate / door sheet metal or other parts and produce abnormal noises; and the wear of the harness causes the power-on function to fail. Utility Model Content
[0004] In view of the deficiencies in the prior art, the first purpose of the utility model is to provide a wiring harness installation structure for a window lifter, which can confine the wiring harness within a designed space to prevent the wiring harness from shaking and colliding, thereby causing abnormal noise and wear and failure.
[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:
[0006] A wire harness installation structure for a glass lifter comprises: a stopper fixed on a door substrate of the glass lifter, the stopper having a cavity, one end of the wire harness being fixed on the door substrate / door sheet metal, and the other end of the wire harness passing through the cavity and being fixed on a slider of the glass lifter.
[0007] Compared with the prior art, the utility model has the following beneficial effects:
[0008] By fixing the limiter on the door base plate, the wiring harness passes through the cavity of the limiter. As one end of the wiring harness moves up and down with the slider, the cavity always confines the wiring harness within the designed space to prevent the wiring harness from shaking and hitting the door base plate or other components, which would cause abnormal noise and wear and failure.
[0009] As a preferred solution, the limiting member is in the shape of an elongated strip and the middle part thereof penetrates through to form the closed cavity, and the inner contour of the limiting member matches the outer surface of the wiring harness.
[0010] As a preferred solution, one end of the limiting member is provided with a separable / connectable connection module.
[0011] As a preferred solution, at least two limiting members are provided, and the lengths of the limiting members are unequal and all extend along the length direction of the guide rail.
[0012] As a preferred solution, the limiting member is in a long strip shape, and both ends of the limiting member are bent in the same direction and fixed on the door substrate.
[0013] As a preferred solution, the slider of the glass lifter is provided with an opening groove and a hook with opposite opening directions, and a connection block is fixed on the wire harness. When the connection block is inserted into the opening groove, the wire harness is stuck in the hook.
[0014] As a preferred solution, the slider of the glass lifter is provided with a clamping groove and a hook, and a connection block is fixed on the wire harness. When the connection block is clamped in the clamping groove, the wire harness is stuck in the hook.
[0015] Another object of the present utility model is to propose a glass lifter, including the wire harness installation structure described in any one of the above.
[0016] On the one hand, the glass lifter can limit the wire harness within the designed space, avoiding the wire harness from shaking and hitting, thereby causing abnormal noise and wear failure. On the other hand, fewer parts are added to the existing lifter, and the occupied space in the car door is also small, and the structure is compact.
[0017] As a preferred solution, the glass lifter is applied to glass color change, glass display of text or video. Description of the Drawings

[0025] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments; the structures described in various embodiments can be freely combined without conflicts in terms of structure or principle.

It is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation to the present utility model. In addition, terms such as "first", "second", etc. are only used for distinguishing descriptions and cannot be understood as indicating or implying relative importance.
[0028] With the development of the automotive industry, the technological sense of automobiles has gradually increased. In the prior art, multifunctional technologies (such as zoned color change, heating, video playback, etc.) have been incorporated into window glass; to achieve the above functions, the glass needs to be electrically connected to a power supply device through a wire harness 4. The present utility model proposes a wire harness installation structure for a window regulator. For the convenience of understanding this technical solution, the wire harness installation structure will be described in combination with the window regulator; the following will illustrate some embodiments of the present utility model with reference to the accompanying drawings.
[0029] Specifically, as Figure 1 shown, the window regulator includes a door substrate 1 and a motor, a guide rail 2 and a slider 3 installed inside the door substrate 1. The motor drives the slider 3 to slide up or down along the guide rail 2 through a steel wire rope, thereby completing the lifting operation of the glass; this part is the prior art and will not be elaborated here. Plug connectors 5 are fixedly provided at both ends of the wire harness 4.
[0030] The wire harness installation structure of the window regulator includes: a limit member 6, as combined Figure 2 shown, the limit member 6 has a cavity and is fixedly installed on the inner side of the door substrate 1. One end of the wire harness 4 is fixed on the door substrate 1 (it can also be fixed on the door sheet metal or other fixed structures), and the plug connector 5 on this end can be connected to the plug of the door (the plug of the door is electrically connected to the power supply device of the whole vehicle); this end of the wire harness 4 can be located inside / outside the door substrate 1. Exemplarily, a through hole is provided on the door substrate 1, and the wire harness 4 passes through the through hole. A plastic plug is designed at the through hole to ensure sealing. At the same time, a hole is also opened in the middle of the plug to ensure that the wire harness 4 can pass through. The plug is closely attached to the wire harness 4 to ensure sealing. The other end of the wire harness 4 passes through the cavity of the limit member 6 and is fixed on the slider 3 of the window regulator. A plug connector 5 is also fixedly provided on this end of the wire harness 4, and this plug connector 5 is connected to the plug of the glass.
[0031] Adopting the above solution, by fixedly installing the limit member 6 on the door substrate 1 and the wire harness 4 passing through the cavity of the limit member 6, during the up and down movement of one end of the wire harness 4 along with the slider 3, the cavity always restricts the wire harness 4 within the designed space (i.e., within the cavity), avoiding the wire harness 4 from shaking and hitting the door substrate or other components to generate abnormal noises and the wire harness 4 from wearing and causing the power-on function to fail.
[0032] In a preferred embodiment, as Figure 1 and Figure 2 shown, the limit member 6 is strip-shaped and extends along the direction of the guide rail 2. The middle part of the limit member 6 is penetrated left and right to form a closed cavity. Of course, the length of the cavity should at least meet the requirement that one end of the wire harness 4 can smoothly move up and down with the slider 3 to the upper dead point and the lower dead point (the specific design of the upper dead point and the lower dead point depends on the lifting height of the glass). In this way, the completely closed cavity can better limit the wire harness 4, especially avoiding the impact and wear between the wire harness 4 and the inner side of the door substrate 1 when the door substrate 1 moves. In addition, the structure of the limit member 6 is simple, easy to manufacture and cost-saving.
[0033] Furthermore, the inner contour of the limit member 6 is designed to match the outer surface size of the wire harness 4; Exemplarily, the width of the cavity is slightly larger than the outer diameter of the wire harness 4, that is, the wire harness 4 has a clearance fit with the cavity of the limit member 6, which can not only reduce the frictional loss between the wire harness 4 and the limit member 6, but also enable the limit member 6 to further reduce the shaking amplitude of the wire harness 4 and ensure the stability of the wire harness 4 trajectory.
[0034] For economy, the limit member 6 can be integrally formed with the door substrate 1. In addition, the limit member 6 can also be detachably connected to the inner side of the door substrate 1 by connection methods such as snap-fasteners / screws, which is convenient for maintenance and replacement.
[0035] In a preferred embodiment, the material of the stopper 6 is recommended to be self-lubricating and wear-resistant material, such as POM. Furthermore, the outer skin of the harness 4 is made of wear-resistant and vibration-damping materials, such as Teflon material, chloroprene rubber, etc., which can ensure the intact color change function throughout the life cycle of the lifter.
[0036] In a preferred embodiment, one end of the stopper 6 is designed as a detachable / connectable connection module 601. Specifically, Figure 2 As shown, a lower hook extending upward is fixedly provided at one end of the limiting member 6, and an upper hook extending downward is also fixedly provided on the limiting member 6, and the shape of the upper hook matches the shape of the lower hook; the upper hook and the lower hook constitute a connecting module 601.
[0037] Since the limiting member 6 is elastic, the operator applies a thrust to the upper hook and / or the lower hook to separate the two and form an opening; the wiring harness 4 can now slide along the opening into the cavity of the limiting member 4; then the external force is removed and the limiting member 6 is reset until the upper hook and the lower hook are engaged, so that the cavity of the limiting member 6 is reclosed; in this way, the wiring harness 4 can easily pass through the limiting member 6 and be well limited by the limiting member 6.
[0038] In a preferred embodiment, Figure 1 As shown, at least two limiting members 6 are provided, and the limiting effect on the wiring harness 4 is enhanced by increasing the number of limiting members 6 . Figure 1 Take two limiters 6 as an example. Since one end of the wire harness 4 is fixed on the door substrate 1, the closer the wire harness 4 is to the guide rail 2, the larger its shaking radius is during movement. Therefore, the two limiters 6 are extended along the length direction of the guide rail 2 and arranged side by side. The lengths of the two limiters 6 are set to be different. Specifically, the length of the limiter 6 close to the guide rail 2 is longer than the length of the other limiter 6. Correspondingly, the cavity of the limiter 6 close to the guide rail 2 is also longer than the other limiter 6. Different parts of the wire harness 4 are limited by different limiters 6, and the wire harness 4 is more accurately limited in the cavity, reducing the shaking of the wire harness 4 and improving the limiting effect.
[0039] It should be understood that the number of the limiting members 6 depends on the distance between the connection points at both ends of the wiring harness 4 ; and the length of the limiting members 6 depends on the stroke of the guide rail 2 .
[0040] In a preferred embodiment, Figure 5 As shown, the stopper 6 is in the shape of a long strip, and the two ends of the stopper 6 are bent in the same direction and fixed on the door base plate 1. The structure of this stopper 6 is simpler than that of the above-mentioned stopper 6. The stopper 6 and the inner wall of the door base plate 1 together form a closed cavity, which plays a role in limiting the random shaking of the wire harness 4. Furthermore, the bending length of the two ends of the stopper 6 can be made slightly larger than the diameter of the wire harness 4, that is, the shaking of the wire harness 4 is reduced, and at the same time, the wire harness 4 and the stopper 6 are clearance-matched to reduce the wear of the two.
[0041] In a preferred embodiment, Figure 3 As shown, the sliding block 3 of the glass lifter is provided with an opening slot 7 and a hook 8, and the opening directions of the opening slot 7 and the hook 8 are opposite, and the opposite here includes completely departing from each other and also includes approximately opposite. For example, Figure 3 The opening directions of the middle opening slot 7 and the hook 8 are substantially opposite. The opening slot 7 is designed to be through and open at the right end, and the opening direction of the hook 8 is substantially to the left. Figure 4 As shown, the wiring harness 4 is fixed with a connecting block 9, which includes a block-shaped head and a strip-shaped protrusion fixed together, and the width of the head is greater than the width of the opening slot 7 (the width direction is Figure 3 The upper and lower directions in the middle of the drawing are arranged to limit the wiring harness 4. The outer contour of the protrusion matches the opening slot 7. In addition, the design position of the hook 8 is to ensure that when the connecting block 9 is inserted into the opening slot 7, a part of the wiring harness 4 can be caught in the hook 8.
[0042] like Figure 3 and Figure 4 As shown, during assembly, the connection block 9 is inserted from right to left into the open slot 7, a part of the wire harness 4 is clamped in the hook 8, and the connection between one end of the wire harness 4 and the slider 3 is completed. The open slot 7 and the hook 8 play a limiting role on the wire harness 4. In this way, the connection between the wire harness 4 and the slider 3 is firm and the limiting structure is simple, and the assembly and disassembly of the wire harness 4 and the slider 3 is convenient and the structure is simple.
[0043] In a preferred embodiment, the main difference between this embodiment and the above-mentioned embodiment is that a slot (not shown in the figure) is designed on the slider 3 instead of the open slot 7, and accordingly, the connecting block 9 is designed as a clamping head that can be elastically deformed and then engaged with the slot; when the connecting block 9 is engaged in the slot, the wiring harness 4 is clamped in the hook 8.
[0044] Furthermore, the connecting block 9 is designed as a rubber block and is integrally formed with the wiring harness 4. During assembly, there is no need to first complete the assembly of the rubber block and the wiring harness 4, thus saving assembly time and cost.
[0045] The utility model also proposes a glass lifter, such as Figure 5 As shown, it is configured with any of the above-mentioned wire harness installation structures.
[0046] On the one hand, the window lifter can limit the wiring harness 4 within the designed space to prevent the wiring harness 4 from shaking and hitting, thereby causing abnormal noise and wear and tear. On the other hand, only a limiter 6 needs to be added to the existing lifter, with fewer added parts, less space occupied in the door, and a compact structure.
