Description

Technical Field

[0001] This application relates to the field of external wiring harness protection devices, and more specifically, to wiring harness boxes and vehicles. Background Technology

[0002] A related technology provides a cable protection box with a cable routing channel inside for external wiring harnesses to pass through, which is used to protect the external wiring harnesses. However, with the development of technology, the radial dimension of the external wiring harnesses has increased, which can easily affect the interior space of the vehicle. Utility Model Content

[0003] This application provides a wiring box and a vehicle to address the issue of how to reduce the impact of external wiring harnesses on the vehicle's interior space.

[0004] According to one aspect of this application, a cable guard box is provided, including a box body and a fixing part. The box body has a cable routing channel for external cable harnesses to pass through, and the cable routing channel has an inlet and a first outlet opposite each other along the length direction of the cable guard box; along the height direction of the cable guard box, the size of the first outlet is larger than the size of the inlet. One end of the fixing part is connected to the outside of the box body, and the fixing part is used to fix at least a portion of the external cable harness extending out of the first outlet.

[0005] The aforementioned cable box, because the size of the first outlet is larger than the size of the inlet along the height direction, allows the external wiring harness passing through the cable box to be divided into multiple bundles and extend out from the first outlet, and arranged along the height direction at the first outlet position. This helps to reduce the width dimension of the portion of the cable box near the first outlet, and also helps to reduce the space occupied by the external wiring harness extending from the first outlet along the width direction, thereby increasing the passenger's activity space and reducing the impact of the external wiring harness on the vehicle's interior space.

[0006] In one embodiment, the external wiring harness includes multiple sub-external wiring harnesses that extend from a first outlet. An external wiring harness connector is provided at the end of each sub-external wiring harness away from the first outlet. The fixing portion has multiple snap-fit ​​portions that are spaced apart from each other along the extending direction of the fixing portion, and each snap-fit ​​portion engages with a corresponding external wiring harness connector.

[0007] In one embodiment, the housing includes a base plate and two side plates, each protruding from one side of the base plate. The two side plates are positioned opposite each other along their height and spaced apart to define a cable routing groove between them. One end of a fixing part is connected to the side of one of the side plates away from the cable routing groove.

[0008] In one embodiment, the wiring box is used for installation between the vehicle body and the door sill trim. Two side panels protrude from the base plate on the side of the wiring box closest to the vehicle body along the width direction. The wiring box also includes a limiting structure disposed on the base plate and / or the side panels, the limiting structure being able to abut against the door sill trim along the width direction to limit the door sill trim along the width direction.

[0009] In one embodiment, the door sill trim includes a trim body and a snap-fit ​​element. The trim body covers a portion of the vehicle body on the side facing inwards. One end of the snap-fit ​​element is connected to the side of the trim body closer to the vehicle body in the width direction. A gap exists between the snap-fit ​​element and the trim body in the width direction. The limiting structure includes a first limiting structure. One side of the first limiting structure is connected to the side of the side panel away from the wiring channel and extends in the height direction away from the side panel. The first limiting structure includes a first limiting portion that can pass through the gap to limit the door sill trim in the width direction.

[0010] In one embodiment, the first limiting portion is connected to the side of the side plate near the bottom plate along the width direction. The first limiting structure also includes a second limiting portion, one end of which is connected to the end of the first limiting portion that extends out of the gap. The second limiting portion extends along the width direction so that it can abut against the snap-fit ​​member along the length direction, thereby limiting the snap-fit ​​member along the length direction.

[0011] In one embodiment, the cable guard box is used for installation between the vehicle body and the door sill trim. Two side panels protrude from the base plate along the width direction of the cable guard box towards the vehicle body. The cable guard box also includes a second limiting structure that protrudes along the width direction from the base plate away from the cable routing channel, and the second limiting structure is capable of supporting the door sill trim along the width direction.

[0012] In one embodiment, the housing has multiple cable tie holes that communicate with cable routing channels. Each cable tie hole is used to allow multiple cable ties to pass through.

[0013] According to another aspect of this application, a vehicle is provided, including a door sill panel, a body, an external wiring harness, and a wiring enclosure as described in any of the above embodiments. The wiring enclosure is mounted between the door sill panel and the body. The external wiring harness passes through a wiring channel.

[0014] In one embodiment, the vehicle also includes a carpet, one end of which extends along the width of the wiring box to the side of the door sill panel near the undercarriage. The wiring box extends along the height of the door sill panel to the side of the door sill panel near the undercarriage and is located between the carpet and the vehicle body.

[0067] Some embodiments of this application are described in detail. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0068] Example

[0069] Figure 1 This is a side view of vehicle 1 in one embodiment of this application; Figure 2 for Figure 1 A partial structural schematic diagram of the door sill trim 200 and the vehicle body 300 in the embodiment shown. Figure 3 for Figure 1 A partial structural schematic diagram of the cable protection box 100 and the vehicle body 300 in the embodiment shown. Figure 4 for Figure 1 Cross-sectional view of the wiring box 100, door sill trim 200 and body 300 in the illustrated embodiment.

[0070] See Figures 1 to 3This application provides a vehicle 1, including a door sill trim 200, a body 300, an external wiring harness 400, and a wiring box 100. Combined with... Figure 4 As shown, the wiring box 100 is installed between the door sill trim 200 and the vehicle body 300. The wiring box 100 is provided with a wiring channel 10a through which the external wiring harness 400 passes. Optionally, the external wiring harness 400 may be a wiring harness of the vehicle 1.

[0071] Thus, by providing a cable tray 100, the external wiring harness 400 within the cable tray 10a is protected, and the external wiring harness 400 is confined between the cable tray 100 and the vehicle body 300. The cable tray 10a can constrain the routing of the external wiring harness 400, allowing the external wiring harness 400 to be routed in the required direction.

[0072] For ease of understanding, this application embodiment uses the length direction X, width direction Y, and height direction Z of the cable guard box 100 for description. The length direction X, width direction Y, and height direction Z are three non-parallel directions in a spatial coordinate system. In subsequent embodiments, the length direction X, width direction Y, and height direction Z are described as three mutually perpendicular reference directions in a three-dimensional Cartesian coordinate system. The directions shown in this application embodiment are used to help understand the relative positional relationships of the components, but do not limit their specific directions. In use, the length direction X can be parallel to the front-rear direction of vehicle 1, the width direction Y can be parallel to the left-right direction of vehicle 1, and the height direction Z can be parallel to the up-down direction of vehicle 2.

[0073] In some embodiments, as Figure 2 and Figure 4 As shown, vehicle 1 also includes a carpet 500, one end of which extends along the width direction Y of the wiring box 100 to the side of the door sill trim 200 near the bottom of the vehicle. The wiring box 100 extends along the height direction Z to the side of the door sill trim 200 near the bottom of the vehicle and is located between the carpet 500 and the body 300 to provide space between the carpet 500 and the body 300 to accommodate the external wiring harness 400.

[0074] In some embodiments, as Figures 2 to 4As shown, the vehicle body 300 includes a door sill (not shown) and an A-pillar inner panel assembly 301. The end of the door sill near the front of the vehicle along the length direction X is connected to the A-pillar inner panel assembly 301. A door sill trim 200 covers the side of the door sill near the interior of the vehicle and the portion of the A-pillar inner panel assembly 301 near the door sill. Therefore, the door sill trim 200 extends beyond the door sill along the length direction X towards the front of the vehicle, improving the aesthetics of the door sill trim 200. Optionally, a wiring box 100 is installed between the A-pillar inner panel assembly 301 and the door sill trim 200 and fixed relative to the A-pillar inner panel assembly 301. A wiring channel 10a is provided on the side of the wiring box 100 near the A-pillar inner panel assembly 301 along the width direction Y.

[0075] In some embodiments, the cable protection box 100 is snapped into the A-pillar inner panel assembly 301 and is fixed relative to the A-pillar inner panel assembly 301 by fasteners.

[0076] Figure 5 for Figure 1 A schematic diagram of the assembly state of the cable guard box 100 and the external wire harness 400 in the embodiment shown. Figure 6 for Figure 1 A schematic diagram of the assembly state of the cable protection box 100 and the external wire harness 400 in the embodiment shown from another perspective. Figure 7 for Figure 1 A schematic diagram of the cable protection box 100 in the illustrated embodiment.

[0077] See Figures 5 to 7 This embodiment provides a cable protection box 100, which includes a box body 10 and a fixing part 20. The box body 10 is provided with a cable routing groove 10a for external cable harnesses 400 to pass through. The cable routing groove 10a has an inlet 10a1 and a first outlet 10a2 opposite to each other along the length X of the cable protection box 100. Along the height Z of the cable protection box 100, the size of the first outlet 10a2 is larger than the size of the inlet 10a1. One end of the fixing part 20 is connected to the outside of the box body 10, and the fixing part 20 is used to fix at least a portion of the external cable harnesses 400 that protrudes from the first outlet 10a2.

[0078] In the aforementioned cable box 100, since the size of the first outlet 10a2 is larger than the size of the inlet 10a1 along the height direction Z, the external wire harness 400 passing through the cable box 100 can be divided into multiple bundles and extend out from the first outlet 10a2, and arranged along the height direction Z at the position of the first outlet 10a2. At least some of the external wire harnesses 400, after extending from the first outlet 10a2, can be fixed to the fixing part 20 respectively. Therefore, since the radial dimension is reduced after the external wire harness 400 is divided into multiple bundles, it is beneficial to reduce the dimension along the width direction Y of the portion of the cable box 100 near the first outlet 10a2, and to reduce the space occupied by the external wire harness 400 along the width direction Y at the position of the fixing part 20. This reduces the space occupied by both the external wire harness 400 and the cable box 100 near the first outlet 10a2, thereby reducing the impact of the external wire harness 400 on the vehicle interior space, increasing the passenger's movement space along the width direction Y, and improving ride comfort.

[0079] In use, for example, when the cable guard box 100 is installed between the door sill trim 200 and the A-pillar inner panel assembly 301, the first cable outlet 10a2 is located on the side of the cable inlet 10a1 along the length direction X, closer to the front of the vehicle. This allows the external wiring harness 400 to extend from the cable inlet 10a1 near the door sill into the cable routing groove 10a, where it is divided into multiple bundles before extending out from the first cable outlet 10a2. Consequently, the door sill trim 200 can fit more snugly against the A-pillar inner panel assembly 301 along the width direction Y, thereby increasing the legroom for front passengers. Similarly, when the cable guard box 100 extends along the height direction Z between the carpet 500 and the A-pillar inner panel assembly 301, the carpet 500 can also fit more snugly against the A-pillar inner panel assembly 301 along the width direction Y.

[0080] Specifically, such as Figure 7 As shown, let the inlet 10a1 have a first dimension L1 along the height direction Z, and let the first outlet 10a2 have a second dimension L2 along the height direction Z, where the second dimension L2 is greater than the first dimension L1. Combined with... Figure 6 As shown, the external wire harness 400 is divided into a first external wire harness 401 and a second external wire harness 402 in the wiring groove 10a. The radial dimensions of the first external wire harness 401 and the second external wire harness 402 are both smaller than the radial dimension of the external wire harness 400 that passes through the inlet 10a1.

[0081] In some embodiments, as Figure 6 As shown, the cable tray 10a also has a second cable outlet 10a3, which is located on one side of the box 10 along the height direction Z. The external cable harness 400 also includes a third external cable harness 403. The external cable harness 400 is further divided into a third external cable harness 403 in the cable tray 10a. The third external cable harness 403 passes through the second cable outlet 10a3 to meet the wiring requirements in different directions.

[0082] In some embodiments, the fixing portion 20 extends in a plane perpendicular to the width direction Y to provide a larger wiring space in the plane perpendicular to the width direction Y, which is beneficial to further reduce the space occupied by the external wire harness 400 in the width direction Y at the location of the fixing portion 20.

[0083] Figure 8 for Figure 1 A schematic diagram of the cable protection box 100 in the illustrated embodiment from another perspective.

[0084] In some embodiments, as Figure 5 As shown, the external wiring harness 400 includes multiple sub-external wiring harnesses 4011, which extend from the first outlet 10a2. An external wiring harness connector 600 is provided at the end of each sub-external wiring harness 4011 away from the first outlet 10a2. The external wiring harness connector 600 is used to connect the sub-external wiring harness 4011 to other vehicle wiring harnesses. Figure 8 As shown, the fixing part 20 is provided with a plurality of snap-fit ​​parts 21, which are spaced apart from each other along the extending direction of the fixing part 20. Each snap-fit ​​part 21 is respectively snapped into one of a plurality of external wiring harness connectors 600. Thus, by setting the snap-fit ​​parts 21 to snap into the external wiring harness connectors 600, the ease of assembling and disassembling the external wiring harness connectors 600 from the fixing part 20 is improved. Furthermore, since the multiple snap-fit ​​parts 21 are spaced apart from each other along the extending direction of the fixing part 20, the multiple external wiring harness connectors 600 can be arranged along the extending direction of the fixing part 20, thereby reducing the space occupied by a single external wiring harness connector 600 in the width direction Y, and further increasing the occupant's movement space in the width direction Y. In this embodiment, the first external wiring harness 401 is divided into a plurality of sub-external wiring harnesses 4011.

[0085] In use, first align the external wire harness connector 600 with the corresponding snap-fit ​​part 21, and then press the external wire harness connector 600 toward the side closer to the snap-fit ​​part 21 so that the external wire harness connector 600 snaps into the snap-fit ​​part 21.

[0086] Figure 9 for Figure 1 A schematic diagram of the assembly state of the wiring box 100, door sill trim 200 and body 300 in the embodiment shown from another perspective.

[0087] In some embodiments, as Figure 8As shown, the housing 10 includes a base plate 11 and two side plates 12. The two side plates 12 protrude from one side of the base plate 11, and are arranged opposite each other and spaced apart along the height direction Z to define a cable routing groove 10a between the two side plates 12. One end of the fixing part 20 is connected to the side of one of the side plates 12 away from the cable routing groove 10a, so as to fix the external wire harness 400 extending from the first cable outlet 10a2 relative to the fixing part 20, and to prevent the fixing part 20 from occupying the space of the base plate 11 away from the cable routing groove 10a, so as to avoid increasing the size of the cable protection box 100 along the width direction Y.

[0088] In some embodiments, as Figure 8 As shown, the cable guard box 100 is used for installation between the vehicle body 300 and the door sill trim 200. Two side panels 12 protrude from the bottom plate 11 along the width direction Y towards the vehicle body 300 (see...). Figure 9 The cable guard box 100 also includes a limiting structure 30, which is provided on the bottom plate 11 and the side plate 12. The limiting structure 30 can abut against the sill panel 200 in the width direction Y to limit the sill panel 200 in the width direction Y, so as to reduce the deformation or displacement of the sill panel 200 in the width direction Y during use, and provide more stable support for the sill panel 200 when it is stepped on.

[0089] In other embodiments, the limiting structure 30 may also be provided on the base plate 11 or the side plate 12.

[0090] Figure 10 for Figure 1 A schematic diagram of the sill plate 200 in the illustrated embodiment.

[0091] In some embodiments, as Figure 9 and Figure 10 As shown, the door sill trim 200 includes a trim body 201 and a snap-fit ​​member 202. The trim body 201 covers a portion of the vehicle body 300 on the side facing the interior. One end of the snap-fit ​​member 202 is connected to the side of the trim body 201 along the width direction Y near the vehicle body 300. A gap 200a is formed between the snap-fit ​​member 202 and the trim body 201 along the width direction Y. Figure 8 As shown, the limiting structure 30 includes a first limiting structure 31. One side of the first limiting structure 31 is connected to the side of the side panel 12 away from the wiring groove 10a, and extends along the height direction Z towards the side away from the side panel 12. The first limiting structure 31 includes a first limiting part 311, which can pass through the gap 200a to limit the sill trim 200 along the width direction Y. In this embodiment, the first limiting part 311 and the snap-fit ​​member 202 are attached to each other along the side of the vehicle 1 near the trim body 201.

[0092] In some embodiments, as Figure 8 and Figure 9As shown, the first limiting part 311 is connected to the side of the side plate 12 along the width direction Y near the bottom plate 11. The first limiting structure 31 also includes a second limiting part 312, one end of which extends out of the gap 200a from the first limiting part 311 (see...). Figure 10 One end of the connector is connected, and the second limiting part 312 extends along the width direction Y so that the second limiting part 312 can abut against the snap fastener 202 along the length direction X, thereby limiting the snap fastener 202 along the length direction X.

[0093] In some embodiments, as Figure 8 and Figure 9 As shown, the cable protection box 100 also includes a second limiting structure 32, which protrudes from the bottom plate 11 along the width direction Y on the side away from the cable routing groove 10a. The second limiting structure 32 can be supported on the sill trim 200 along the width direction Y. Optionally, the second limiting structure 32 includes a plurality of limiting ribs 321. In this embodiment, the plurality of limiting ribs 321 are spaced apart along the height direction Z and extend along the length direction X.

[0094] When in use, when the sill panel 200 is not subjected to external force, the second limiting structure 32 is spaced apart from the panel body 201 along the width direction Y. When the sill panel 200 moves closer to the box body 10 under the action of external force, the second limiting structure 32 can abut against the panel body 201 along the width direction Y.

[0095] In some embodiments, as Figure 7 As shown, the box 10 has multiple cable tie holes 10b, which are connected to the cable tray 10a. The multiple cable tie holes 10b are used for multiple cable ties (not shown in the figure) to pass through, so as to provide a restraining effect on the external wire harness 400 at different positions through the multiple cable ties. By providing multiple cable tie holes 10b, it is also beneficial to achieve the weight reduction of the cable protection box 100.

Although this application has been described in detail with reference to the above preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions to the technical solutions of this application should not depart from the spirit and scope of the technical solutions of this application.
