Description

TECHNICAL FIELD

[0001] The utility model belongs to the field of seat armrest, concretely relates to a hinge structure for arranging wire harness of folding armrest. BACKGROUND

[0002] With the increasingly fierce competition in the automobile industry, the configuration of automobile seat armrest is also increasingly high. In addition to being able to be folded relative to the seat, the seat armrest also has a heating function or has a key or control panel for operating the seat, which involves the problem of how to arrange the seat armrest wire harness.

[0003] The armrest wire harness of the existing seat armrest is located inside the armrest framework, a wire harness avoiding groove is provided at the position close to the seat framework hinge, the armrest wire harness is pulled out from the armrest framework through the wire harness avoiding groove, the surface and the foam of the seat backrest have a through hole relative to the position of the wire harness avoiding groove, the armrest wire harness is pulled into the seat through the through hole after being pulled out from the armrest framework and connected with the branch of the bus wire harness. Since the wire harness avoiding groove and the through hole are both near the hinge, the armrest wire harness is arranged in parallel with the hinge. When the seat armrest is folded up and down relative to the hinge, the seat framework, the surface and the foam of the seat backrest are not moved, that is, the through hole is not moved. The armrest wire harness will be pulled with the folding of the seat armrest assembly, so that the through hole on the seat backrest will reciprocally rub the armrest wire harness up and down, thereby generating noise and causing abrasion of the armrest wire harness. SUMMARY

[0004] The utility model discloses a hinge structure for arranging wire harness of folding armrest, which can not pull the armrest wire harness up and down when the seat armrest is folded up and down, so as to avoid reciprocally rubbing the armrest wire harness up and down and solve the problems of noise and wire harness abrasion.

[0005] In order to achieve the above-mentioned purpose, the utility model provides a hinge structure for arranging wire harness of folding armrest, which comprises a hinge and a hollow shaft, the hinge is connected with one end of the hollow shaft, a through hole for the armrest wire harness to pass through is arranged on the hollow shaft, the other end of the hollow shaft is provided with an open end, and the hinge is connected with the seat framework through the hollow shaft.

[0006] Advantages and beneficial effects of the utility model

[0007] 1. The utility model discloses a bold innovation attempt to the arrangement of handrail wire harness, according to the material mechanics, the contribution of the center part material of the pivot to the strength of the pivot is very small, but the contribution to the weight is very big, therefore, the pivot non-fixed cooperation position is shortened in the application, and a hollow shaft is additionally arranged between the pivot and the seat framework, the hollow shaft is equipped with through -hole, and the handrail wire harness is connected with the branch of bus wire harness through the through -hole on the hollow shaft and the open end of the hollow shaft, because the pivot is coaxial with the hollow shaft, so when the seat handrail is folded up and down, the handrail wire harness is not pulled up and down, therefore, the reciprocating friction of the up and down shearing of the handrail wire harness is not formed, and the problems of noise and wire harness abrasion are solved.

[0008] 2. The utility model discloses simple structure, convenient installation does not have the influence of original assembly sequence, and lightens the overall weight. ACCURACY

[0009] In order to more clearly illustrate the technical scheme in the embodiment of the utility model, the following will be needed to use the drawing in the embodiment description briefly introduces, obviously, the drawing in the following description only is the embodiment of the utility model, for the ordinary skilled person in the art comes, under the premise of not paying the creative labor, can also obtain other drawings according to the provided drawing.

[0012] Figure 3 It is the handrail assembly and seat framework assembly position schematic diagram provided by the utility model.

[0013] Reference signs: pivot 1, hollow shaft 2, through -hole 21, seat framework 3, handrail assembly 4, handrail wire harness 5. SPECIFIC IMPLEMENTATION

[0014] The specific implementation of the utility model will be described in detail below in combination with the drawings, and it should be noted that in the description of the utility model, the terms "upper", "lower", "left", "right", "inner", "outer", "front", "rear" and the like indicate the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the utility model and simplifying the description, and do not indicate or imply that the devices or elements referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as a limitation on the utility model.

[0015] As Figure 1 And Figure 2As shown, a rotating shaft structure for folding the armrest wire harness arrangement includes a rotating shaft 1 connected with the armrest assembly 4, the rotating shaft 1 in the embodiment is a spline shaft, the seat framework 3 is connected with the armrest assembly 4 by spline shaft and snap spring in the armrest assembly 4, the length of the rotating shaft 1 is shortened compared with the prior art structure (the rotating shaft 1 is directly connected with the seat framework assembly 3), a hollow shaft 2 with larger diameter than the rotating shaft 1 is additionally arranged between the rotating shaft 1 and the seat framework 3, the left end of the rotating shaft 1 is fixedly connected or integrally connected with the right end of the hollow shaft 2, a through hole 21 is arranged above the hollow shaft 2, and the left end of the hollow shaft 2 is provided with an open end, and the hollow shaft 2 is fixedly connected with the seat framework 3 through the open end.

[0016] As Figures 1-3 shown, when the armrest assembly 4 and the seat framework 3 are assembled, the armrest wire harness 5 is pulled out from the armrest framework through the wire harness avoiding groove, is pulled into the inner cavity of the hollow shaft 2 through the through hole 21, is pulled into the seat interior through the open end of the left end of the hollow shaft 2 to be connected with the branch of the bus wire harness, and finally assembled with the armrest assembly 4 and the seat framework 3 by spline shaft and snap spring in the armrest assembly 4, since the rotating shaft 1 and the hollow shaft 2 are coaxial, the armrest assembly 4 will not pull up and down the armrest wire harness 5 when folding up and down, thus the reciprocating friction of the armrest wire harness up and down shearing is not formed, and the problems of noise and wire harness abrasion are solved.

[0017] Finally, it should be noted that: the above embodiments are only used to illustrate the technical solutions of the embodiments of the present application, and not to limit them; although the embodiments of the present application have been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that they can still modify the technical solutions recorded in the foregoing embodiments, or make equivalent replacement for part or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the embodiments of the present application.
