[0029] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0030] In order to enable those skilled in the art to better understand the present application, the present application is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0031] Please refer to Figures 1 to 3 , Figure 1 A schematic diagram of the structure of a wire harness protection device provided in an embodiment of the present application; Figure 2 A schematic diagram of the structure of the wire harness protection device provided in an embodiment of the present application at the line card; Figure 3 This is a schematic diagram of the installation of the wire harness protection device provided in an embodiment of the present application.

[0032] Please refer to Figure 1 and Figure 3 The present application provides a wire harness protection device, including a shell 1 and a wire harness positioning portion; the aforementioned wire harness positioning portion is arranged in the shell 1, and is used to clamp and position the wire harness to be protected; the shell 1 is provided with a wire entry port 3 for the wire harness to be protected to pass through, and the wire entry port 3 is arranged on the side and / or bottom of the shell 1, and the wire entry port 3 gradually shrinks toward the inside of the shell 1 and toward the center of its own cross section.

[0033] The wiring harness protection device provided in this embodiment can position and clamp the wiring harness to be protected in the housing 1, for example, the low-voltage wiring harness at the electric drive axle end and the wiring harness at the vehicle end can be positioned and clamped in the housing 1, and the housing 1 can be used to effectively position the aforementioned low-voltage wiring harness and protect the low-voltage wiring harness and the wiring harness at the vehicle end.

[0034] When the harness protection device is used to position the low-voltage harness and the vehicle-end harness, the risk of the low-voltage harness becoming loose or being worn due to vibration can be reduced.

[0035] When the harness protection device is used to protect the low-voltage harness and the vehicle-end harness, the low-voltage harness and the vehicle-end harness can be inserted from the wire inlet 3, so that the wiring ports of the low-voltage harness and the vehicle-end harness are located inside the housing 1, and the wiring ports of the low-voltage harness and the vehicle-end harness are prevented from being stepped on. In addition, the aforementioned wire inlet 3 is arranged on the side or bottom of the housing 1, and the wire inlet 3 gradually shrinks toward the inside of the housing 1 and toward the center of its own cross section, so the surface of the wire inlet 3 is an inclined surface with a certain curvature, which can prevent water outside the housing 1 from flowing into the wire inlet 3 along the surface of the housing 1, and to a certain extent reduce the risk of external rainwater and dust entering the housing 1 and contacting the wiring ports of the low-voltage harness and the vehicle-end harness.

[0036] The wire harness protection device provided in the present application is further described below in conjunction with the accompanying drawings and implementation examples.

[0037] like Figure 1 and Figure 3 As shown, in some embodiments, the shell 1 is provided with a wire entry port 3, which may include an outer channel opening 31 close to the outer side of the shell 1 and an inner channel opening 32 close to the inner side of the shell 1; wherein the outer channel opening 31 and the inner channel opening 32 are connected to each other, the outer channel opening 31 is a constant diameter channel, and the inner channel opening 32 is a variable diameter channel with a gradually decreasing diameter.

[0038] In the above embodiment, the line inlet 3 includes an outer channel opening 31 and an inner channel opening 32. When rainwater outside the housing 1 flows toward the line inlet 3 along the surface of the housing 1, the rainwater is blocked by the outer channel opening 31 and the inner channel opening 32. Most of the rainwater will stagnate at the outer channel opening 31, and a small amount of rainwater will contact the inner channel opening 32. Part of the rainwater that enters the inner channel opening 32 will also flow to the outer channel opening 31 again under the action of gravity. It can be seen that the above-mentioned line inlet 3 can effectively prevent rainwater from contacting the wiring harness to be protected and its wiring port in the housing 1.

[0039] In the above embodiment, when the low-voltage wire harness and the vehicle-end wire harness are inserted into the housing 1, the low-voltage wire harness and the vehicle-end wire harness can be respectively inserted from different wire inlets 3 of the housing 1. Usually, part of the cable skin of the low-voltage wire harness and the vehicle-end wire harness is stuck at the inner channel opening 32 and does not contact the outer channel opening 31, which can reduce the probability of rainwater flowing into the housing 1 along the cable skin, and further reduce the risk of rainwater contacting the wiring ports of different wire harnesses to be protected in the housing 1.

[0040] Generally, the housing 1 may be provided with a through-hole and a wire-threading bracket; the aforementioned wire-threading bracket may be detachably installed in part of the through-hole. In this embodiment, the inner channel opening 32 of the wire inlet 3 is provided on the aforementioned wire-threading bracket, and the outer channel opening 31 of the wire inlet 3 is defined by the through-hole and the wire-threading bracket, so that the operator can conveniently set a suitable wire inlet 3 for different wire harnesses to be protected, and ensure that each wire harness to be protected is stably and reliably installed in the corresponding wire inlet 3.

[0041] In some embodiments, the shell 1 may include a top plate 11 and a pair of first side plates; wherein the top plate 11 can be detachably mounted on the shell 1; the pair of first side plates are spaced apart from each other, and the pair of first side plates are respectively provided with wire entry ports 3, so that different wire harnesses to be protected can be passed through the shell 1 from different directions.

[0042] In the above embodiment, the top plate 11 is detachably mounted on the shell 1; when the top plate 11 is removed, the wiring harness to be protected can be easily and conveniently installed and removed in the shell 1; when the top plate 11 is installed, the top plate 11 can prevent the operator from stepping on the wiring harness to be protected and prevent rainwater from contacting the wiring harness to be protected and its wiring port.

[0043] In some embodiments, at least a portion of the edge of the top plate 11 is bent and extended downward to guide rainwater to flow down smoothly, avoid rainwater accumulation on the top plate 11 , and prevent rainwater from entering the housing 1 through the installation seam of the top plate 11 .

[0044] On the basis of the above embodiment, the housing 1 may further include a second side plate 12; the edge of the top plate 11 may be bent and extended toward the second side plate 12. In this embodiment, the edge of the top plate 11 is bent and extended toward the second side plate 12, which can guide rainwater to flow down from the second side plate 12, prevent rainwater from flowing down from the first side plate provided with the cable inlet 3, and reduce the risk of rainwater entering the cable inlet 3.

[0045] For reference Figure 1 and Figure 2 In some embodiments, the bottom of the housing 1 is exposed, or the housing 1 includes a bottom plate 13 and the bottom plate 13 is provided with an opening 4. The bottom of the housing 1 presents the above-mentioned design, which can timely discharge rainwater and dust entering the housing 1, prevent water and dust from accumulating in the housing 1, and avoid damage to the wiring harness to be protected and its wiring port.

[0046] In some embodiments, the harness positioning portion includes a wire card 5 ; the wire card 5 has a wire clamping plate for surrounding and squeezing the harness to be protected, and the wire clamping plate is suspended in the housing 1 , so that the connection ports of different harnesses to be protected can be suspended in the housing 1 .

[0047] In addition, the wiring harness protection device provided in the present application also positions and clamps the shell 1 on the vehicle body through the fixing bracket 3, ensuring that the low-voltage wiring harness and the vehicle-end wiring harness waiting for protection are reliably connected to the vehicle body.

[0048] In summary, the wiring harness protection device provided in the present application can fix the wiring harness to be protected and its wiring port at a designated position in the housing 1, which can effectively fix the wiring harness to be protected and reduce the risk of water ingress or loosening of the wiring harness to be protected.

[0049] The wiring harness protection device provided in the present application can be installed above the main reduction gearbox housing assembly of the electric drive axle, for example, it can be installed in the middle of the top of the main reduction gearbox housing assembly of the electric drive axle, to optimize the spatial layout of the bridge end and ensure the wiring safety of the electric drive axle.
