Description

Technical Field

[0001] The invention relates to the technical field of automobiles, and in particular to an automobile sun visor and wiring harness installation structure and method. Background Art

[0002] The car sun visor is a component installed on the car to prevent glare. It plays an important role in some occasions. For example, in sunny weather, the sunlight shining through the front window of the car may affect the driver's vision, thus affecting driving safety. The car sun visor needs to be fixed on the front roof beam of the car through the installation assembly. During driving, the sun visor blocks the sunlight and reduces the impact of sunlight on the driving process.

[0003] With the diversification of car models, when the car is high and the human body sits low, the head space of the driver and the co-driver is increased, resulting in the Z-direction height of the sun visor in the open state not meeting the human-machine arrangement, and the car sun visor cannot fully block the sunlight; in addition, the existing car sun visor installation method is a front top cross beam stamping mounting boss, the sun visor wiring harness passes through the beam cavity, and is limited by the height of the boss stamped by the front top cross beam. The problem that the Z-direction height of the sun visor in the open state does not meet the human-machine arrangement is still unable to solve the problem. In addition, the height of the stamped boss is small, which makes the operating space of the assembly workers small, and the assembly process is not visible, and the wiring harness needs to be taken out from the top cross beam cavity. The wiring harness hole is easy to cut hands and cut the wiring harness, making the sun visor assembly difficult. Summary of the invention

[0004] In view of the shortcomings of the prior art, the purpose of the present invention is to provide a car sun visor and wiring harness installation structure and method. The arrangement of a mounting bracket can solve the problem that the Z-direction height of the sun visor in the open state does not meet the human-machine layout requirements. At the same time, the wiring harness can be routed outside the front top beam and threaded through the mounting bracket, reducing the difficulty of installation.

[0005] In order to achieve the above object, the present invention is implemented through the following technical solutions:

[0006] In the first aspect, a car sun visor and wiring harness installation structure includes a front top cross beam, a mounting bracket is provided at the inner end portion of the front top cross beam, a through hole and a U-shaped groove are opened on the mounting bracket, and a wiring harness enters from the inner side of the front top cross beam through the U-shaped groove between the mounting bracket and the front top cross beam and passes through the through hole to be connected to the sun visor wiring harness, and the mounting bracket is clamped with the sun visor mounting block through the through hole.

[0007] As a further implementation method, the mounting bracket has a U-shaped cross-section, including two side plates and a bottom plate between the two side plates, and a storage space for the wiring harness and the sun visor wiring harness is formed between the mounting bracket and the front top cross beam.

[0008] As a further implementation, the through hole is provided on the bottom plate of the mounting bracket, and the U-shaped groove is provided on the side plate.

[0009] As a further implementation method, a guide hole is provided on the front top cross beam at the U-shaped groove for connecting with a wiring harness buckle.

[0010] As a further implementation, one end of the wiring harness buckle is clamped on the guide hole, and the other end buckles the corresponding wiring harness.

[0011] As a further implementation method, a flange hole is provided on the front top cross beam, and the flange hole is located on the axis of the through hole. The flange at the edge of the flange hole is used to protect the wiring harness so that the wiring harness can be inserted into the flange hole.

[0012] As a further implementation method, the flanged hole is formed by installing a flanged rubber ring inside the opening of the front top cross beam.

[0013] As a further implementation method, positioning holes are provided on both sides of the through hole on the bottom plate for installing and positioning the sun visor mounting block.

[0014] As a further implementation, the two side plates of the mounting bracket are connected to form a closed structure on one side close to the side enclosure, and are open on the other side.

[0015] In a second aspect, a method for installing a car sun visor and a wiring harness adopts any of the above-mentioned car sun visor and wiring harness installation structures, comprising the following steps:

[0016] The body sheet metal is turned upside down in the factory, and the mounting bracket is welded to the front top cross beam of the car. The indoor wiring harness at the side A-pillar extends to the wiring harness branch at the inner side of the front top cross beam, enters between the mounting bracket and the front top cross beam through the U-shaped groove and passes through the through hole. After connecting the wiring harness connector with the connector of the sun visor wiring harness, the wiring harness is inserted into the mounting bracket and fixed at the guide hole with a snap.

[0017] The beneficial effects of the present invention are as follows:

[0018] 1. The present invention provides a mounting bracket on the inner side of the front top cross beam, and the mounting bracket 4 has a set height, which is equivalent to lowering the height of the sun visor, thereby solving the problem that when the height of the car is high and the sitting posture of the human body is low, the head space of the driver and the co-driver is increased, resulting in the Z-direction height of the sun visor in the open state not meeting the human-machine arrangement, and the car sun visor cannot fully block the sunlight; the mounting bracket is covered so that the wiring harness can enter between the mounting bracket and the front top cross beam from the outside of the front top cross beam through the U-shaped groove and pass through the through hole to connect with the sun visor wiring harness, so the operation space is large, and the operation can be visualized, the installation is simple and fast, there is no need to dig the wires from the inner cavity of the front top cross beam, and the risk of cutting hands is reduced.

[0019] 2. The present invention is provided with a flanging hole and a wiring harness buckle, which can realize the fixation of the wiring harness after the sun visor is installed. The setting of the flanging can protect the wiring harness from being cut; the flanging can be formed by a flanging rubber ring, which is elastic and can clamp the wiring harness to a certain extent, thereby better fixing the wiring harness.

[0029] It should be noted that the following detailed descriptions are illustrative and intended to provide further explanation of the present invention. Unless otherwise specified, all technical and scientific terms used in the present invention have the same meanings as those commonly understood by those skilled in the art to which the present invention belongs.

[0030] like Figure 6As shown, the prior art adopts a front top cross beam stamped boss 10 structure, and the sun visor wiring harness passes through the cross beam cavity, but is limited by the height of the stamped boss of the front top cross beam, and cannot solve the problem that the Z-direction height of the sun visor in the open state does not meet the human-machine layout. In addition, the small height of the stamped boss makes the operating space of the assembly workers small, resulting in difficulties in assembling the sun visor.

[0031] Embodiment 1

[0032] In a typical embodiment of the present invention, reference is made to Figure 1-Figure 5 As shown, a car sun visor and wiring harness installation structure includes a front top cross beam 2, a mounting bracket 4 and a wiring harness buckle 7.

[0033] The mounting bracket 4 is covered at both end portions of the inner side of the front top cross beam 2 and is used as the mounting bracket 4 for the main driver's seat and the co-driver's seat respectively.

[0034] like Figure 1 and Figure 4 As shown, the cross section of the mounting bracket is U-shaped, including two side plates and a bottom plate between the two side plates, and the side edges of the two side plates close to the opening end of the mounting bracket 4 are folded outwards to be folded with the inner side of the front top cross beam to achieve welding of the mounting bracket on the front top cross beam 2. The side edges of the two side plates away from the front top cross beam 2 are connected by the bottom plate.

[0035] The mounting bracket 4 is provided with a through hole 41 and a U-shaped groove 42 . The through hole 41 is provided on the bottom plate of the mounting bracket 4 , and the U-shaped groove 42 is provided on one of the side plates of the mounting bracket 4 , which is the side plate of the mounting bracket 4 close to the rear end of the vehicle.

[0036] The mounting bracket 4 has a set height, so that an accommodation space for the wiring harness 31 and the sun visor harness is formed between the mounting bracket 4 and the front roof beam 2, and the U-shaped groove 42 and the through hole 41 are connected through the accommodation space to serve as an extension channel for the harness.

[0037] The wiring harness 31 enters the accommodation space between the mounting bracket and the front top cross beam 2 from the inner side surface of the front top cross beam 2 through the U-shaped groove 42 and passes through the through hole 41, and is used to be connected to the sun visor wiring harness. The mounting bracket 4 is clamped with the sun visor mounting block 61 through the through hole 41 to install the sun visor 6 on the mounting bracket 4.

[0038] like Figure 1 As shown, since the mounting bracket 4 is covered on the front top cross beam 2, and the side panels are inclined relative to the front top cross beam 2, a U-shaped groove 42 is provided on one of the side panels, and a guide hole 21 is provided on the part of the front top cross beam 2 exposed at the U-shaped groove 42 for connecting with the wiring harness buckle 7.

[0039] One end of the wire harness buckle is clamped on the guide hole 21 to fix the guide hole 21 to the wire harness buckle 7. The other end of the wire harness buckle 7 buckles the corresponding wire harness to prevent the wire harness from moving and generating noise. The wire harness buckle 7 of this embodiment is fixed on the wire harness. During installation, you only need to clamp the wire harness buckle 7 on the guide hole 21.

[0040] like Figure 1 As shown, positioning holes are provided on both sides of the through hole on the bottom plate of the mounting bracket 4, which are used to install and position the sun visor mounting block 61. When the sun visor mounting block 61 is installed with the mounting bracket 4, its clamping part is clamped at the through hole, and positioning pins are provided on both sides of the clamping part. When clamped, the positioning pins are inserted into the positioning holes to achieve installation positioning.

[0041] The two side plates of the mounting bracket 4 are connected to form a closed structure near the side enclosure. The closed structure is arranged near the side enclosure and has a triangular shape, and the other side is open.

[0042] like Figure 4 As shown, the front top cross beam 2 is provided with a flange hole 22, and the flange hole 22 is located on the axis of the through hole, that is, the flange hole 22 is located directly above the through hole. Figure 4 The viewing angle is an inverted vehicle body viewing angle. When assembling auto parts in the factory, when installing structures such as sun visors, the vehicle body sheet metal is installed inverted to improve installation efficiency and reduce installation difficulty.

[0043] After the wiring harness 31 is connected to the sun visor harness, the connected harness needs to be inserted back into the accommodation space between the mounting bracket 4 and the front roof crossbeam 2 .

[0044] By providing the flanging hole 22, when storing the wire harness, the overlong wire harness can be inserted into the flanging hole 22, so that part of the wire harness is accommodated in the front top cross beam 2 in the flanging hole 22. The flanging at the edge of the flanging hole 22 is used to protect the wire harness so that the wire harness can be inserted into the flanging hole 22. By providing the flanging at the opening, the flanging hole 22 can be prevented from cutting the wire harness. Specifically, the flanging hole 22 is formed by installing a flanging rubber ring on the inner side of the opening of the front top cross beam 2. The flanging rubber ring is elastic, and part of the wire harness is inserted into the flanging hole 22. The flanging rubber ring can clamp the wire harness and fix the wire harness. The flanging rubber ring combined with the wire harness buckle can fix the wire harness in the mounting bracket 4 to prevent the wire harness from vibrating due to bumps during vehicle driving.

[0045] like Figure 1As shown, the indoor wiring harness 3 extends from the side A-pillar 1, is attached to the side A-pillar 1 and extends to the end position of the front top cross beam 2, and is attached to the inner side of the front top cross beam 2 and extends along its length direction, extending to the mounting bracket 4 to form a group of wiring harness 31 branches, and the branch wiring harness 31 is used to extend through the U-shaped groove, the accommodating space, and the through hole. A wiring harness connector 5 is provided at the end, and the wiring harness connector 5 and the sun visor wiring harness connector of the sun visor 6 are plugged in and matched to achieve the connection between the wiring harnesses.

[0046] The indoor wiring harness 3 of this embodiment extends through the inner side surface of the front top beam, that is, the indoor wiring harness 3 is located on the outside of the front top beam 2, and the wiring is not routed from the inner cavity of the front top beam 2. The wiring harness 31 is passed through the U-shaped groove 42, the accommodating space, and the through hole from the outside of the front top beam 2. The operating space is large, and the operation can be visualized. The installation is simple and fast, and there is no need to dig the wires from the inner cavity of the front top beam 2, reducing the risk of cutting hands.

[0047] The difficulty of installation can be changed by adjusting the size of the U-shaped groove 42. It is preferred to enlarge the U-shaped groove 42 so that the operation process is simple and quick when threading the wiring harness and installing the wiring harness buckle, which solves the problem of difficult assembly for operators and improves the portability of the sun visor and sun visor wiring harness assembly.

[0048] The mounting bracket 4 has a set height, which is equivalent to lowering the height of the sun visor, thereby solving the problem that when the car is at a high height and the human body sits low, the head space for the driver and the co-driver is increased, resulting in the Z-direction height of the sun visor in the open state not meeting the human-machine layout, and the car sun visor cannot fully block the sunlight.

[0049] Embodiment 2

[0050] In a typical embodiment of the present invention, reference is made to Figure 1-Figure 5 As shown, a method for installing a car sun visor and a wiring harness, using the car sun visor and wiring harness installation structure of embodiment 1, comprises the following steps:

[0051] In the automobile factory, the automobile body sheet metal is inverted, and the mounting bracket 4 is welded to the two ends of the inner side of the front top cross beam 2 of the automobile. The indoor wiring harness 3 at the side A-pillar 1 extends the wiring harness 31 branch at the inner side of the front top cross beam 2. The wiring harness 31 branch is inserted into the U-shaped groove 42, enters the accommodating space between the mounting bracket 4 and the front top cross beam 2 through the U-shaped groove 42 and passes out from the through hole 41, so that the wiring harness connector 5 is exposed to the outside to facilitate connection with the sun visor wiring harness connector. After connecting the wiring harness connector 5 with the connector of the sun visor wiring harness, the wiring harness is inserted into the mounting bracket 4, and the wiring harness at the guide hole 21 is fixed by the wiring harness buckle 7. The wiring harness buckle 7 is clamped with the guide hole, and part of the wiring harness is clamped in the flange hole 22 to fix the wiring harness. Then, the sun visor mounting block 61 is clamped and connected with the mounting bracket 4 to achieve the installation of the sun visor 6.

[0052] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
