Description

Technical Field

[0001] The utility model relates to the technical field of the installation structure of vehicle interior parts, and particularly relates to a wire harness guiding structure for a vehicle sill area. Background Art

[0002] Most of the high-voltage battery packs of electric passenger vehicles are arranged at the bottom of the occupant compartment floor. Compared with traditional fuel vehicles, the Z-direction (vehicle up and down direction) and Y-direction (vehicle left and right direction) clearances between the body floor and the sill trim in the sill areas on both sides are insufficient. At the same time, with the popularization of the lightweight design concept, the front and rear floor skeletons tend to apply the die-casting aluminum process. Compared with the traditional steel structure, the die-cast aluminum parts need to occupy more space in the Z-direction.

[0003] Currently, as Figure 1 shown, the guiding wire groove 01 of the wire harness main trunk in the area of the rear floor die-cast aluminum skeleton and the rear floor cross beam adopts a Z-direction flat design. When the wire harness main trunk extends downward along the X-direction (the front and rear direction of the vehicle) through the die-cast aluminum skeleton 02 and the floor cross beam 03 to the body floor 04, it can only meet the Z-direction clearance requirements in the areas of the floor cross beam 03 and the die-cast aluminum skeleton 02, and cannot control the Y-direction clearance of the wire harness main trunk in the area of the body floor 04 at the same time, resulting in an interference problem between the guiding wire groove 01 in the area of the body floor 04 and the interior trim panel. Summary of the Utility Model

[0004] The technical problem to be solved by the utility model is that the unreasonable wire harness guiding structure in the existing sill area causes the problem that the space occupied in the Y-direction in the body floor area is too large.

[0005] In view of the above technical problems, the utility model provides the following technical solutions:

[0006] A vehicle wire harness guiding structure includes a guiding wire groove. The guiding wire groove includes a first wire groove area, a transition wire groove area, and a second wire groove area that are sequentially extended along the X-direction. The height difference between the lower surface of the first wire groove area and the lower surface of the second wire groove area is greater than the height difference between the upper surface of the first wire groove area and the upper surface of the second wire groove area. The length of the second wire groove area along the Y-direction is less than the length of the first wire groove area along the Y-direction, where the X-direction is the front and rear direction of the vehicle, and the Y-direction is the left and right direction of the vehicle.

[0007] In some embodiments of the utility model, the notch of the guiding wire groove faces the Y-direction, and the height difference between the lower groove wall of the first wire groove area and the lower groove wall of the second wire groove area is greater than the height difference between the upper groove wall of the first wire groove area and the upper groove wall of the second wire groove area.

[0008] In some embodiments of the present utility model, a first mounting plate is provided in the first wire groove area, and the first mounting plate is arranged on the lower groove wall of the first wire groove area. A second mounting plate is provided in the second wire groove area, and the second mounting plate is arranged on the lower groove wall of the second wire groove area. Connecting holes are respectively provided on the first mounting plate and the second mounting plate.

[0009] In some embodiments of the present utility model, a plurality of guiding ribs are arranged at intervals on the bottom of the guiding wire groove, and the plurality of guiding ribs divide the guiding wire groove into two wire harness accommodating areas.

[0010] In some embodiments of the present utility model, the length of the guiding rib in the Y direction is the same as the length of the second wire groove area in the Y direction.

[0011] In some embodiments of the present utility model, the free end of the guiding rib has a hooking structure on the side facing the lower groove wall of the guiding wire groove.

[0012] In some embodiments of the present utility model, a guiding plate protruding in the Y direction is provided on the groove wall of the first wire groove area on the side far from the second wire groove area.

[0013] The present utility model also provides a vehicle, including a vehicle body frame and the vehicle wire harness guiding structure as described above. Among them, the vehicle body frame is divided into a first area and a second area by a floor cross beam, the first area is higher than the second area, the first wire groove area is connected to the first area of the vehicle body frame, and the second wire groove area is connected to the second area of the vehicle body frame.

[0014] In some embodiments of the present utility model, the vehicle body frame further includes a sill longitudinal beam, and the second wire groove area is attached to the longitudinal side wall of the sill longitudinal beam.

[0015] In some embodiments of the present utility model, the upper surface of the second wire groove area is lower than the upper surface of the sill longitudinal beam; or the upper surface of the second wire groove area is flush with the upper surface of the sill longitudinal beam.

[0016] The technical solution of the present utility model has the following technical effects compared with the prior art:

[0017] In the vehicle wiring harness guiding structure provided by the present utility model, the guiding wire groove includes a first wire groove area, a transition wire groove area, and a second wire groove area that are sequentially extended along the X direction. Among them, the height difference between the lower surface of the first wire groove area and the lower surface of the second wire groove area is relatively large, while the height difference between the upper groove wall of the first wire groove area and the upper groove wall of the second wire groove area is relatively small. That is to say, the Z-direction accommodation space of the second wire groove area is larger than that of the first wire groove area, and the Y-direction length of the second wire groove area is less than the Y-direction length of the first wire groove area. That is to say, the Y-direction accommodation space of the second wire groove area is smaller than that of the first wire groove area. The first wire groove area of the entire guiding wire groove is a flat groove body along the left-right direction of the vehicle, and the second wire groove area is a flat groove body structure along the up-down direction of the vehicle. When the guiding wire groove is installed in the sill area of the vehicle, the first wire groove area of the guiding wire groove is located in the first area with a relatively high height separated by the floor cross beam in the vehicle skeleton, and the second wire groove area of the guiding wire groove can be located in the second area with a relatively low height separated by the floor cross beam in the vehicle skeleton. The entire guiding wire groove will not affect the installation and layout of other components on the vehicle skeleton. Description of the Drawings

For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0026] In addition, the technical features involved in different embodiments of the present utility model described below can be combined with each other as long as they do not conflict with each other.

[0027] As Figures 2 - 4 shown is the vehicle wiring harness guiding structure provided by the present utility model, which is used for guiding the wiring harness in the vehicle sill area, so that the wiring harness is arranged along its interior to avoid interference between the wiring harness and other components.

[0028] Among them, the vehicle wiring harness guiding structure includes a guiding wire groove. The guiding wire groove extends as a whole along the X direction (i.e., the front-rear direction of the vehicle). The guiding wire groove 10 includes a first wire groove area 11, a second wire groove area 12 extending along the X direction, and a transition wire groove area 13 located between the two. The height difference between the lower groove wall of the first wire groove area 11 and the lower groove wall of the second wire groove area 12 is greater than the height difference between the upper groove wall of the first wire groove area 11 and the upper groove wall of the second wire groove area 12. The width of the second wire groove area 12 along the Y direction (i.e., the left-right direction of the vehicle) is smaller than the length of the first wire groove area 11 along the Y direction.

[0029] In the above vehicle wiring harness guiding structure, the height difference between the lower surface of the first wire groove area 11 and the lower surface of the second wire groove area 12 is greater than the height difference between the upper groove wall of the first wire groove area 11 and the upper groove wall of the second wire groove area 12. That is, the accommodation space of the second wire groove area 12 in the Z direction (i.e., the up and down direction of the vehicle) is greater than the accommodation space of the first wire groove area 11 in the Z direction. The width of the second wire groove area 12 is smaller than the width of the first wire groove area 11. That is, the accommodation space of the second wire groove area 12 in the Y direction is smaller than the accommodation space of the first wire groove area 11 in the Y direction. That is, the first wire groove area 11 of the guiding wire groove 10 is a flat groove body along the left and right direction of the vehicle, while the second wire groove area 12 is a flat groove body structure along the up and down direction of the vehicle. When the guiding wire groove 10 is installed in the sill area of the vehicle, the first wire groove area 11 of the guiding wire groove 10 is located in the first area with a higher height separated by the floor cross beam in the vehicle skeleton, and the second wire groove area 12 of the guiding wire groove 10 can be located in the second area with a lower height separated by the floor cross beam in the vehicle skeleton. The entire guiding wire groove 10 will not affect the installation and arrangement of other components on the vehicle skeleton.

[0030] Specifically, in an optional implementation manner, as Figure 3 shown, the notch of the guiding wire groove 10 faces the Y direction. It includes a groove bottom extending in the vertical direction and upper and lower groove walls respectively located on both sides of the groove bottom. Among them, the upper and lower groove walls of the first wire groove area 11 and the second wire groove area 12 of the guiding wire groove 10 extend in the horizontal direction, and the upper and lower groove walls of the transition wire groove area 13 of the guiding wire groove 10 have a certain angle relative to the horizontal direction. The height difference between the lower groove wall of the first wire groove area 11 and the lower groove wall of the second wire groove area 12 is greater than the height difference between the upper groove wall of the first wire groove area 11 and the upper groove wall of the second wire groove area 12. Among them, the wiring harness can extend into its interior along the notch of the guiding wire groove 10 and realize extension in the X direction. In other alternative implementation manners, the notch of the guiding wire groove 10 faces the Z direction, for example, facing the lower side of the vehicle. Specifically, taking the YZ plane as the reference plane, the reference value of the width W1 * height H1 of the second wire groove area 12 is: (20 mm - 30 mm) * (60 mm - 80 mm), the reference value of the width W2 * height H2 of the second wire groove area 12 is: (60 mm - 80 mm) * (20 mm - 30 mm), the reference value of the Z - direction height difference ΔH between the two is 65 mm - 85 mm, and the reference value of the Y - direction width ΔW is 70 mm - 90 mm.

[0031] Specifically, the guiding wire groove 10 is integrally formed by a cast aluminum skeleton, and its connection method with the vehicle body skeleton 20 is not unique. In one implementation manner, as Figure 4As shown, the first wire groove area 11 is provided with a first mounting plate 111, and the second wire groove area 12 is provided with a second mounting plate 121. Connecting holes are respectively provided on the first mounting plate 111 and the second mounting plate 121. The guiding wire groove 10 is connected and fixed to the vehicle body frame 20 by passing through the connecting holes on the first mounting plate 111 and the second mounting plate 121 and the fastening screws on the vehicle body frame 20.

[0032] More specifically, the first mounting plate 111 is arranged on the lower groove wall of the first wire groove area 11, and the second mounting plate 121 is arranged on the lower groove wall of the second wire groove area 12. Among them, the first mounting plate 111 is integrally cast with the first wire groove area 11 and has the same wall thickness as its lower groove wall. The second mounting plate 121 is integrally cast with the second wire groove area 12 and has the same wall thickness as its lower groove wall.

[0033] Specifically, since the wire harnesses in the vehicle usually vary greatly in size, in order to enable wire harnesses of different sizes to extend and transition reasonably along the guiding wire groove 10, in one implementation, as Figure 2 shown, a number of guiding ribs 14 are arranged at intervals on the bottom of the guiding wire groove 10. The number of guiding ribs 14 divides the guiding wire groove 10 into two wire harness accommodating areas. Among them, due to the large height difference between the lower groove wall of the first wire groove area 11 and the lower groove wall of the second wire groove area 12, the transition arc of its transition wire groove area 13 is large. The area between the guiding rib 14 and the lower groove wall of the guiding wire groove 10 is used to accommodate wire harnesses with a larger diameter, such as wire harnesses with a cross-sectional area greater than 10mm 2 ; while the area between the guiding rib 14 and the upper groove wall of the guiding wire groove 10 is used to accommodate wire harnesses or wire harness bundles with a smaller diameter, such as wire harnesses with a cross-sectional area less than 10mm 2 ; which is beneficial to the control of the wire harness posture and can avoid the problem of short service life caused by too large a bending angle of the wire harness with a larger diameter.

[0034] More specifically, in a specific implementation, as Figure 2 shown, the guiding ribs 14 are respectively arranged at the end of the first wire groove area 11 (the side far from the second wire groove area 12), the connection area between the first wire groove area 11 and the transition wire groove area 13, the middle area of the transition wire groove area 13, the connection area between the transition wire groove area 13 and the second wire groove area 12, and the end of the second wire groove area 12 (the side far from the first wire groove area 11).

[0035] Specifically, in an optional implementation, the length of the guiding rib 14 in the Y direction is the same as the width of the second wire groove area 12. Since the width of the second wire groove area 12 is relatively narrow, the length of the guiding rib 14 in the Y direction being the same as the width of the second wire groove area 12 can ensure that the wire harness located between the two can be reliably installed and fixed.

[0036] More specifically, since the wire harness between the guiding rib 14 and the lower groove wall of the guiding wire groove 10 is relatively thick, in order to further improve the guiding and fixing of the wire harness, one side of the free end of the guiding rib 14 facing the lower groove wall of the guiding wire groove 10 is provided with a hooking structure 141. When the wire harness is installed, the hooking structure 141 can further limit the position of the wire harness and prevent the wire harness from slipping out of the notch.

[0037] Specifically, as Figure 2 shown, on the groove wall of the first wire groove area 11 on the side far from the second wire groove area 12, there is a guiding plate 112 protruding along the Y direction. Among them, two guiding plates 112 are provided, and the two guiding plates 112 are respectively oppositely arranged on the upper groove wall and the lower groove wall of the first wire groove area 11. The wire harness extends outwards from the notch at the end of the first wire groove area 11 (that is, the end far from the second wire groove area 12) along the side of the guiding plate 112 protruding in the Y direction.

[0038] Specifically, in an optional implementation manner, the guiding structure further includes a cover plate (not shown in the figure) for closing the guiding wire groove 10. The cover plate covers the notch side of the guiding wire groove 10, and the shape and size of the cover plate match those of the guiding wire groove 10. When installing the above guiding structure on the vehicle body frame 20, after installing the wire harness in the guiding wire groove 10, cover the cover plate on the notch side of the guiding wire groove 10, and then fix the assembled guiding structure on the vehicle body frame 20 through fastening screws.

[0039] The present utility model also provides a specific implementation manner of a vehicle. As Figure 3 shown, the vehicle includes a vehicle body frame 20 and the above vehicle wire harness guiding structure; among them, the vehicle body frame 20 is divided into a first area 21 and a second area 22 by a floor cross beam 23. Among them, the floor cross beam 23 extends along the Y direction, the first area 21 is higher than the second area 22, the first wire groove area 11 is connected to the first area 21 of the vehicle body frame 20, and the second wire groove area 12 is connected to the second area 22 of the vehicle body frame 20.

[0040] The vehicle body frame 20 further includes a sill longitudinal beam 24. The sill longitudinal beam 24 extends along the X direction. The bottom wall of the second wire groove area 12 is attached to the longitudinal side wall of the sill longitudinal beam 24. Since the width of the second wire groove area 12 is small and it is attached to the sill longitudinal beam 24, the space occupied by it along the Y direction in the second area 22 of the vehicle body frame 20 is very small, and it can avoid interference between the wire harness and other components.

[0041] The upper surface height of the threshold longitudinal beam 24 is slightly lower than the upper surface of the threshold longitudinal beam 24, or the upper surface of the second wire groove area 12 is at the same height as the upper surface of the first area 21 of the vehicle body frame 20. The upper groove wall of the second wire groove area 12 is lower than or flush with the upper surface of the threshold longitudinal beam 24, which can ensure that the second wire groove area 12 of the guide groove body 10 does not interfere with other components located above the threshold longitudinal beam 24.

[0042] Obviously, the above embodiments are only examples for clear illustration and not limitations on the implementation manners. For those of ordinary skill in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to enumerate all implementation manners here. And the obvious changes or modifications derived therefrom are still within the protection scope of the present utility model.
