Description

Technical Field

[0001] This utility model belongs to the field of bus manufacturing technology, specifically relating to a cable conduit structure for buses. Background Technology

[0002] With the development of new energy vehicles, new energy buses have become the mainstream product in the current bus industry, especially pure electric buses, which are more favored by consumers. The requirements for their driving range and battery capacity are becoming increasingly stringent, typically demanding large battery capacity and long driving range. To accommodate more battery capacity, some batteries are usually installed on the roof. Holes are made in the roof lining at appropriate locations to run the high-voltage wiring harness, and a battery cover is then installed on the roof to protect the batteries. An inspection door needs to be added to the battery cover for battery maintenance. This results in the battery cover not being completely sealed, leading to water leakage. Water can flow along the high-voltage wiring harness into the air conditioning ducts. Utility Model Content

[0003] The purpose of this utility model is to provide a conduit structure for passenger vehicles, which solves the problem that water will seep into the air conditioning duct along the high-voltage wiring harness when a battery is installed on the roof.

[0004] The technical solution adopted by this utility model is a cable conduit structure for a passenger vehicle, including a cable conduit and a water inlet pipe. The cable conduit includes a U-shaped bend and a water collection pipe located at the bottom of the U-shaped bend. The cable conduit is installed on the lower surface of the passenger vehicle roof cover by a mounting plate. The head of the U-shaped bend is vertical and the top extends out of the upper surface of the passenger vehicle roof cover. The tail of the U-shaped bend extends horizontally outward by a set distance. The water collection pipe is vertically connected to the water inlet pipe, and the water inlet pipe extends outside the vehicle.

[0005] Furthermore, the aforementioned conduit and water pipe are both arranged inside the air conditioning duct, with the water pipe extending from the rear of the vehicle body to the outside along the air conditioning duct.

[0006] Furthermore, the aforementioned mounting plate is a square plate perpendicular to the head of the conduit, the head of the conduit passes through the mounting plate and is fixedly connected to it, and there is a set distance between the mounting plate and the top of the conduit.

[0007] Furthermore, the aforementioned mounting plate is welded or bonded to the roof lining of the bus.

[0008] Furthermore, the diameter of the aforementioned water inlet pipe is larger than that of the water collection pipe, and the direction of the water inlet pipe is relatively downward relative to the overall direction of the water collection pipe.

[0009] Compared with the prior art, the beneficial effect of this utility model is that the cable conduit, water collection pipe and water diversion pipe provided by this utility model form a cable conduit structure for passenger vehicles. When water seeps into the cable conduit along the high-voltage wiring harness, it is collected by the water collection pipe and flows out of the vehicle through the water diversion pipe, thus preventing water from flowing directly into the vehicle.

[0011] Figure 2 This is a schematic diagram of the conduit structure. Detailed Implementation

[0012] The present invention will be further explained below with reference to the accompanying drawings to enable those skilled in the art to better understand it.

[0013] Example 1

[0014] like Figure 1-2 As shown, a bus wiring conduit structure includes a wiring conduit 1 and a water inlet pipe 4. The wiring conduit 1 includes a U-shaped bend 2 and a water collection pipe 3 located at the bottom of the U-shaped bend 2. The wiring conduit 1 is installed on the lower surface of the bus roof cover 6 via a mounting plate 5. The head of the U-shaped bend 2 is vertical and its top extends out of the upper surface of the bus roof cover 6. The tail of the U-shaped bend 2 extends horizontally outward by a set distance. The water collection pipe 3 is vertically connected to the water inlet pipe 4, which extends outside the vehicle. When water seeps into the wiring conduit 1 along the high-voltage wiring harness, it is collected by the U-shaped bend 2 and led through the water collection pipe 3 to the water inlet pipe 4 to flow outside the vehicle, thus preventing water from flowing directly into the vehicle.

[0015] Furthermore, both the aforementioned conduit 1 and water pipe 4 are arranged within the air conditioning duct 7, which is the air outlet channel for the bus's electric air conditioning system. Its cross-section is semi-elliptical, with one side installed on the bus roof and the other side installed on the bus side wall, serving as a space for the high-voltage wiring harness. The water pipe 4 extends from the rear of the bus body to the outside along the air conditioning duct 7, ensuring that the wiring harness and pipes are arranged neatly and without taking up extra space.

[0016] Mounting plate 5 is a square plate perpendicular to the head of conduit 1. The head of conduit 1 passes through mounting plate 5 and is fixedly connected to it. There is a set distance between mounting plate 5 and the top of conduit 1 so that conduit can be fixed under bus roof skin 6 through mounting plate 5 and the top of conduit 1 can drain water from bus roof. Mounting plate 5 is welded or bonded to bus roof skin 6.

[0017] In order to facilitate the water in the conduit 1 to be drawn out through the water inlet pipe 4 as soon as possible, the diameter of the water inlet pipe 4 is larger than that of the water collection pipe 3, and the direction of the water inlet pipe 4 is relatively downward relative to the water collection pipe 3.

[0018] The bus wiring conduit structure, composed of the above-mentioned components, is designed with minimal changes to the current bus structure. When water seeps into the wiring conduit along the high-voltage wiring harness, it is collected by the water collection pipe and flows out of the vehicle through the water diversion pipe.

[0019] The embodiments described above are merely preferred embodiments of the present invention and are not intended to limit the scope of the present invention. Various modifications and improvements made by those skilled in the art to the technical solutions of the present invention without departing from its design spirit and principles should fall within the protection scope defined by the claims of the present invention.
