DETAILED DESCRIPTION

[0028] In order for those skilled in the art to better understand the technical solutions of the present application, the present application will be further described in detail below in combination with the drawings and specific embodiments.

[0029] The embodiment of the present application provides a seat wire harness fixing support and a vehicle, wherein the vehicle comprises a seat framework 20 and a seat wire harness fixing support 10, the seat framework 20 is provided with a horizontal pipe 201, the horizontal pipe 201 is arranged below a seat cushion, and the seat wire harness fixing support 10 is installed on the seat framework 20 and is used for fixing a connection wire harness. The connection wire harness can be a connection wire harness of electronic equipment such as a heating function, a ventilation system and an electric adjustment device carried by a vehicle seat. The seat wire harness fixing support 10 provides a fixing point for each connection wire harness and fixes the connection wire harness. The arrangement of the connection wire harness below the vehicle seat is more regular, and the problems of difficult installation and even interference and wear with the installation of surrounding parts caused by disordered arrangement of the connection wire harness are avoided.

[0030] Specifically, as shown in FIG. 1, the seat wire harness fixing support 10 comprises a fixing plate 1, a wire harness fixing hole 2, a horizontal pipe clamping part 3, a positioning part 4, a first reinforcing rib 5, a fastener 6, a vertical plate 7 and a third reinforcing rib 8. Figure 1 and Figure 2As shown, the seat wire harness fixing support 10 comprises a fixing plate 1 provided with wire harness fixing holes 2 for fixing the connecting wire harness, which can be fixed by fixing buckles or can be fixed by fixing buckles and plug-in connectors. The number, size, shape and position of the wire harness fixing holes 2 are not limited and can be set according to actual conditions. In the installed state, all the wire harness fixing holes 2 can be fixed by the buckles and the connecting wire harness or plug-in connector, or part of the wire harness fixing holes 2 can be fixed by the buckles and the connecting wire harness or plug-in connector, and part of the wire harness fixing holes 2 can be left empty to form a reserved hole, so as to fix the newly added connecting wire harness when other electronic devices are added subsequently. Through the wire harness fixing holes 2 of the seat wire harness fixing support 10, fixing points can be provided for the connecting wire harness and the plug-in connector, and the connecting wire harness can be effectively prevented from being pulled to cause functional failure.

[0031] The fixing plate 1 is also provided with a cross pipe clamping portion 3 provided with a clamping groove 31, and the cross pipe clamping portion 3 is clamped and matched with the cross pipe 201 through the clamping groove 31 to fix the fixing plate 1 with the seat framework 20.

[0032] The cross pipe 201 is located below the seat framework 20, and the structure of the groove wall of the clamping groove 31 is matched with the structure of the outer wall surface of the cross pipe 201. For example, the cross section (radial section) of the cross pipe 201 is in a circular structure, the cross section of the clamping groove 31 is also in a circular arc structure, and the width of the slot of the clamping groove 31 is smaller than the diameter of the circular arc structure, i.e. the width of the slot of the clamping groove 31 is smaller than the diameter of the cross pipe 201. In the clamped state, the cross pipe 201 can be prevented from being separated from the clamping groove 31 to ensure the clamping stability.

[0033] The fixing plate 1 is also provided with a positioning portion 4, and the seat framework 20 is also provided with a corresponding positioning structure 202. During installation, the positioning portion 4 of the fixing plate 1 is positioned and matched with the positioning structure 202, and the cross pipe clamping portion 3 is clamped and fixed with the cross pipe 201, which is convenient to operate and does not need to adjust the position of the seat wire harness fixing support 10 multiple times, thereby effectively improving the installation efficiency.

[0034] Specifically, as shown in the figure, Figure 1 The positioning structure 202 provided on the seat framework 20 is a positioning hole, and the positioning portion 4 provided on the fixing plate 1 is a positioning protrusion. During installation, the positioning protrusion is inserted into the positioning hole to realize positioning. The positioning protrusion and the positioning hole can be in interference fit to ensure the stability in the installed state while realizing positioning.

[0035] Of course, the positioning structure 202 of the seat framework 20 can also be a positioning protrusion, and the positioning portion 4 of the fixed plate 1 can also be a positioning hole. When the positioning portion 4 is provided as a positioning protrusion and the positioning structure 202 is provided as a positioning hole, only the existing seat framework 20 needs to be processed to have a positioning hole, which can be applied to the seat framework 20 in the prior art, has a wide range of applications, and is good in flexibility.

[0036] During installation, the positioning portion 4 is first positioned and matched with the positioning structure 202, and then the clamping groove 31 of the cross pipe clamping portion 3 is clamped and matched with the cross pipe 201, so that the seat wire harness fixing support 10 is fixed with the seat framework 20, and the installation operation is relatively convenient.

[0037] In the seat wire harness fixing support 10, the cross pipe clamping portion 3 and the positioning portion 4 can be provided with only one, respectively. The cross pipe clamping portion 3 is clamped with the cross pipe 201 to achieve fixation, and the positioning portion 4 is positioned and matched with the positioning structure to achieve positioning. Compared with the scheme in which only the positioning portion 4 is provided and the cross pipe clamping portion 3 is not provided, fixation can be achieved by the cross pipe clamping portion 3 and the cross pipe 201. Compared with the scheme in which only the clamping portion is provided for clamping fixation and the positioning portion 4 is not provided, the positional stability in the installed state can be ensured, and the positional shift of the seat wire harness fixing support 10 relative to the seat framework 20 can be avoided.

[0038] As shown in FIG. 1, Figure 2 The clamping portion includes two clamping plates, which are arranged side by side and form a clamping groove 31 therebetween. In the depth direction of the clamping groove 31, the height of one clamping plate is higher than that of the other clamping plate. That is, the two clamping plates are arranged opposite to each other to form two side walls of the clamping groove 31, and the height of one side wall is higher than that of the other side wall. The side wall with the relatively higher height can form a guide wall.

[0039] For convenience of description, the clamping plate with the relatively higher height is referred to as a first clamping plate, and the clamping plate with the relatively lower height is referred to as a second clamping plate. During installation, the seat wire harness fixing support 10 is moved so that the first clamping plate is attached to the cross pipe 201 on the side of the second clamping plate, and then the seat wire harness fixing support 10 is moved in the depth direction of the clamping groove 31. The cross pipe 201 can slide relative to the cross pipe clamping portion 3 to attach the first clamping plate, and then the cross pipe 201 can be located in the clamping groove 31.

[0040] Of course, in the present embodiment, the heights of the two clamping plates can be set to be the same, and the height of the first clamping plate can be set to be higher than that of the second clamping plate. The first clamping plate can provide a guiding effect for the installation of the seat wire harness fixing support 10, facilitate the clamping and matching between the clamping groove 31 and the cross pipe 201, and effectively improve the installation efficiency.

[0041] The side of the clamping plate opposite to the clamping groove 31 is also provided with a reinforcing structure connected between the clamping plate and the fixed plate 1 to ensure the structural strength of the horizontal pipe clamping part 3, thereby ensuring the clamping stability between the horizontal pipe clamping part 3 and the horizontal pipe 201.

[0042] In the embodiment, the reinforcing structure is not specifically limited, for example, a rib plate can be arranged between the clamping plate and the fixed plate 1 to form the reinforcing structure, or the clamping plate can be arranged in a thickened structure to form the reinforcing structure. Figure 2 As shown in the figure, the side wall surface of the clamping plate opposite to the clamping groove 31 is also provided with a hollow groove 33. The hollow groove 33 can ensure the clamping strength between the horizontal pipe clamping part 3 and the horizontal pipe 201, and can also achieve the effects of weight reduction and cost reduction.

[0043] As shown in the figure, the side wall surface of the clamping plate opposite to the clamping groove 31 is also provided with a hollow groove 33. The hollow groove 33 can ensure the clamping strength between the horizontal pipe clamping part 3 and the horizontal pipe 201, and can also achieve the effects of weight reduction and cost reduction. Figure 4 As shown in the figure, the side wall surface of the clamping plate opposite to the clamping groove 31 is also provided with a hollow groove 33. The hollow groove 33 can ensure the clamping strength between the horizontal pipe clamping part 3 and the horizontal pipe 201, and can also achieve the effects of weight reduction and cost reduction.

[0044] The fixed plate 1 is also provided with a fastener mounting hole 13, and is fixed to the seat framework 20 through a bolt, a screw or other fastener 6 to ensure the stability and avoid loosening between the seat wire harness fixing support 10 and the seat framework 20 due to vibration during driving or adjustment of the seat.

[0045] The fixed plate 1 is also provided with a counterbore 14 which is in communication with the fastener mounting hole 13 and is located on the side surface of the fixed plate 1 away from the horizontal pipe clamping part 3. During installation, the bolt or screw passes through the counterbore 14 and the fastener mounting hole 13 and is fixed to the seat framework 20. The head of the bolt or the screw is located in the counterbore 14 to avoid protruding and interfering or wearing with the connected wire harness or other surrounding parts.

[0046] Of course, in the embodiment, the fixed plate 1 can also be fixed to the seat framework 20 by riveting. When installed by a bolt or a screw, the seat wire harness fixing support 10 can be easily disassembled for subsequent maintenance. If the seat wire harness fixing support 10 is no longer applicable due to the addition of new electronic equipment, the seat wire harness fixing support 10 can also be disassembled and replaced, which is flexible.

[0047] In addition, in the embodiment, during the installation process, the seat wire harness fixing support 10 is first positioned and matched with the positioning structure through the positioning part 4, and is then clamped and fixed with the cross pipe 201 through the cross pipe clamping part 3, and then is fixed with the seat framework 20 through the fastener 6. Therefore, when being fixed through the fastener 6, the seat wire harness fixing support 10 has already been in a fixed state with the seat framework 20, the position of the seat wire harness fixing support 10 is stable, the operation of fixing through the fastener 6 is facilitated, and the number of fasteners 6 can be reduced, for example, only one fastener 6 or two fasteners 6 as shown, without the need to set a plurality of fasteners 6 on the circumferential edge of the fixing plate 1, thereby reducing the requirement for space arrangement. Figure 1

[0048] In the embodiment, the seat wire harness fixing support 10 is a plastic piece formed integrally, and of course, the manufacturing process of the seat wire harness fixing support 10 is not limited, for example, the seat wire harness fixing support 10 can also be a metal piece. Compared with the metal piece, the plastic piece can reduce the overall weight and has relatively low cost, and the integral forming can simplify the manufacturing process and ensure the structural stability between the parts, for example, between the fixing plate 1 and the cross pipe clamping part 3 and the positioning part 4.

[0049] In addition, the fixing plate 1 is also provided with a groove structure corresponding to the cross pipe clamping part 3 on the side away from the cross pipe clamping part 3, and the first reinforcing rib 5 is arranged in the groove structure, so as to ensure the structural stability between the cross pipe clamping part 3 and the fixing plate 1.

[0050] As shown in Figure 2 , the fixing plate 1 is also provided with the second reinforcing rib 11 to ensure the overall structural strength of the fixing plate 1. The fixing plate 1 is also provided with the flange structure 12 in the circumferential direction to strengthen the overall structure of the fixing plate 1 in the circumferential direction. The arrangement of the second reinforcing rib 11 and the flange structure 12 can effectively enhance the structural strength of the fixing plate 1, avoid bending deformation, ensure the wire harness fixing stability and the service life of the fixing plate 1.

[0051] Of course, in the embodiment, the fixing plate 1 can be provided only with the second reinforcing rib 11 without the flange structure 12, or can be provided only with the flange structure 12 without the second reinforcing rib 11, which can be set according to the actual strength requirement of the fixing plate 1.

[0052] In addition, in the embodiment, the specific structure of the fixing plate 1 is not limited, and can be set according to the actual space condition to reserve a certain gap between the fixing plate 1 and other surrounding structures to prevent scratching.

[0053] As shown in Figure 2 and Figure 4 ​As shown, the fixing plate 1 is further fixed with a vertical plate 7, the vertical plate 7 is also provided with a wire harness fixing hole 2 for fixing a connecting wire harness, and a third reinforcing rib 8 is further arranged between the vertical plate 7 and the fixing plate 1 to ensure the structural strength and stability of the vertical plate 7. The axis of the wire harness fixing hole 2 of the vertical plate 7 and the axis of the wire harness fixing hole 2 of the fixing plate 1 can be at a preset included angle to meet the fixing needs of the connecting wire harness at different positions.

[0054] Specifically, the specific size of the preset included angle is not limited, for example, Figure 4 In the embodiment shown, the preset included angle is about 90°, and the preset included angle can also be other angles such as 45°, 60°, etc., which can be set according to actual conditions.

[0055] In addition, in the embodiment, the number and position of the vertical plate 7 are not limited, and the preset included angles corresponding to each vertical plate 7 can be the same or different.

[0056] In the embodiment, the second reinforcing rib 11, the horizontal pipe clamping part 3, the positioning part 4, the flange structure 12, the vertical plate 7, etc. are all arranged on the same side of the fixing plate 1, and the counterbore 14 is located on the side of the fixing plate 1 away from the horizontal pipe clamping part 3. In the installed state, the side of the fixing plate 1 provided with the horizontal pipe clamping part 3 is arranged towards the side of the seat framework 20 and is fixed with the seat framework 20, while the side of the fixing plate 1 away from the seat framework 20 has a simple surface structure and is relatively flat, and a large number of protrusions are not arranged to avoid interference with the installation of other surrounding parts.
