[0001] This invention belongs to the field of vehicle engineering technology, specifically relating to a sealed protective structure for external sensor cables passing through walls. Background Technology

[0002] Displacement, tilt, and angle sensors for wheeled or tracked vehicles are typically located outside the vehicle to measure suspension displacement or wheel rotation angle. Sensor cables often transmit information to the vehicle's internal controller via through-wall electrical connectors. However, due to the harsh working environment outside the vehicle, cables and connectors are generally susceptible to interference from liquids, dirt, and impacts, making them prone to corrosion or damage. Furthermore, the through-wall nature of the cables also affects the vehicle's sealing. Summary of the Invention

[0003] To address the shortcomings of existing technologies, this invention provides a sealed protective structure for external sensor cables passing through walls. This structure not only protects the external sensor cables and electrical connectors, but also seals the sensor cables between them and the vehicle body. Furthermore, it facilitates the maintenance and replacement of sensors by personnel outside the vehicle.

The following embodiments are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0029] Example 1

[0030] A certain tracked vehicle is equipped with an tilt sensor on its external suspension to measure the rotation angle of the swing arm of the rotating shock absorber. The sensor signal needs to be transmitted to the inside of the vehicle body through the wall via electrical transmission for the vibration control of the entire vehicle.

[0031] Example 1 provides a sealed protective structure for the tilt sensor cable passing through a wall, which can be partially referred to as... Figures 1-2The system includes an electrical connector (1), a cable (2), a wall-penetrating seal (3), an interior sealing end cap (4), an exterior sealing end cap (5), an adapter plate (13), a sealing cover (15), and a protective rubber tube (16); the adapter plate (13) has an opening; the wall-penetrating seal (3) is a cylindrical structure with openings at both ends; the cable (2) includes an interior cable (i.e., the end of the cable connecting the interior of the vehicle to the exterior sensor) and an exterior cable (i.e., the end of the cable connecting the exterior sensor to the interior of the vehicle);

[0032] First, drill a hole (30cm in diameter) in the vehicle body (12) at the location where the wall needs to be penetrated. Then, weld the adapter plate (13) onto the vehicle body (12). Note that the center of the hole on the adapter plate (13) should be aligned with the center of the hole on the vehicle body (12). The dimensions of the adapter plate (13) are as follows: Figure 3 As shown;

[0033] The through-wall seal (3) passes through the hole in the adapter plate (13) into the vehicle body and is fixed to the adapter plate (13) by screws M8X16 (9), such as Figure 4 As shown;

[0034] The sealing end cap (4) is installed on the wall seal (3) inside the vehicle using screws M5X12 (7) to protect and restrain the cable. The cable inside the vehicle passes through the reserved hole on the sealing end cap (4) and enters the wall seal (3). The cable outside the vehicle and the electrical connector (1) pass through the reserved hole on the protective rubber tube (16) and the sealing cover (15), and then pass through the reserved hole on the sealing end cap (5) and enter the wall seal (3) to connect with the cable inside the vehicle through the electrical connector (1). The sealing end cap (5) is fixed to the wall seal (3) with screws M4X10 (6). The end of the cable outside the vehicle that protrudes from the sealing end cap (5) is tightened with a metal cable waterproof connector (10) to seal and prevent dust and water. Figure 5 As shown;

[0035] The protective rubber tube (16) is provided with pipe joints (11) at both ends. The end of the protective rubber tube (16) close to the sealing cover (15) is fixedly connected to the sealing cover (15) through the pipe joints (11). The sealing cover (15) is fixed to the adapter plate (13) by screws M8X16 (GB / T5783-2000) and covers the vehicle exterior sealing end cover (5). There is a sealing groove on the contact side between the sealing cover (15) and the adapter plate (13), and a constraint O-ring (14) (4mm in diameter) is fixed inside. The sealing level of the protective cover (15) is IP67, so mud, sand and other substances outside the vehicle cannot enter the vehicle body. The electrical connector (1) is also sealed inside the wall-penetrating seal (3), and the weak points such as cables are protected. The cables and connectors are not easily damaged.

[0036] Practical experience has proven that the sealed protective structure has a good protective effect, with no leakage observed inside the vehicle body and no damage to the cables.

[0037] The above description is only a preferred embodiment of the present invention. It should be noted that for those skilled in the art, any changes, substitutions, combinations, or simplifications made without departing from the technical principles of the present invention should be considered equivalent substitutions, and these improvements and modifications should also be considered within the scope of protection of the present invention.
