Abstract
Description
Technical Field
[0001] This invention relates to the field of air brake new energy commercial vehicle technology, specifically to an air compressor pipeline system for air brake new energy commercial vehicles. Background Technology
[0002] New energy commercial vehicles, especially those with air brakes, rely on electric air compressors to generate compressed air as the power source for their braking systems. In the cold winters of northern regions, ambient temperatures can reach -20°C or even lower. After the vehicle is turned off, a small amount of moisture remains in the pipes from the air compressor to the dryer. At extremely low ambient temperatures, this residual moisture is very likely to freeze, causing blockages inside the pipes.
[0003] When the vehicle is restarted, the blocked pipelines will prevent the air compressor from delivering compressed air to the air reservoirs of each brake circuit, causing the air pressure in the vehicle's braking system to build up slowly or not at all, which seriously affects the vehicle's braking performance and poses a direct threat to driving safety.
[0004] Currently, common solutions to this problem rely on passive insulation or manual drainage after shutdown, lacking effective means to proactively and automatically prevent icing during vehicle operation. These methods are not only inefficient and dependent on the driver's initiative, but also fail to address the root cause of the problem, causing significant inconvenience and safety risks for users operating vehicles in cold regions. Summary of the Invention
[0005] This application provides an air compressor piping system for air-brake new energy commercial vehicles to at least solve one technical problem existing in the related technology.
[0006] This application provides an air compressor piping system for air-brake new energy commercial vehicles, including: a dryer inlet pipe with an electric heating wire installed on the inner or outer surface of the pipe wall; an ambient temperature sensor for detecting ambient temperature; a vehicle control unit (VCU) electrically connected to the ambient temperature sensor for receiving temperature signals; a relay with a control coil electrically connected to the control output terminal of the VCU; and a heating wire harness branch connected between the load contact of the relay and the electric heating wire for supplying power to the electric heating wire.
[0007] As an optional implementation, the electric heating wire is made of copper and is fixed to the wall of the dryer's air inlet pipe by spiral winding or straight embedding.
[0008] As an optional implementation, the end of the dryer air inlet pipe is provided with a heating wire harness connector to enable pluggable electrical connection between the heating wire harness branch and the electric heating wire.
[0009] As an optional implementation, the system further includes a spiral cooling pipeline and a high-temperature hose, and the dryer inlet pipe is connected to the air compressor storage pipe through the high-temperature hose.
[0010] As an optional implementation, the VCU is pre-configured with a first temperature threshold and a second temperature threshold. When the temperature detected by the ambient temperature sensor is lower than the first temperature threshold, the VCU controls the relay to engage to turn on the heating circuit; when the detected temperature is higher than the second temperature threshold, the VCU controls the relay to disengage to stop heating.
[0011] As an optional implementation, the first temperature threshold is -10°C and the second temperature threshold is 0°C.
[0012] As an optional implementation, the resistance value of the electric heating wire is matched with the power supply voltage so that the heating temperature of the air inlet pipe of the dryer is kept constant below 10°C when energized.
[0013] As an optional implementation, the electric heating wire is a copper wire covered with an insulating layer.
[0014] As an optional implementation, the dryer's air inlet pipe is made of nylon.
[0015] In this embodiment, an air compressor piping system for an air-brake new energy commercial vehicle is provided, comprising: a dryer inlet pipe with an electric heating wire disposed on the inner or outer surface of the pipe wall; an ambient temperature sensor for detecting ambient temperature; a vehicle control unit (VCU) electrically connected to the ambient temperature sensor for receiving temperature signals; a relay with its control coil electrically connected to the control output terminal of the VCU; and a heating wire harness branch connected between the load contact of the relay and the electric heating wire for supplying power to the electric heating wire. By integrating the electric heating wire into the dryer inlet pipe and forming a closed-loop automatic control system with the ambient temperature sensor, VCU, and relay, significant benefits are achieved. This system can automatically start and stop heating according to changes in ambient temperature, realizing proactive and intelligent prevention of pipe icing problems, fundamentally eliminating the major safety hazard of insufficient air pressure in the braking system caused by pipe icing. Its highly integrated structural design not only improves the reliability and durability of the system and avoids the installation and maintenance problems of external heating devices, but also directly heats the pipe, resulting in high heat transfer efficiency and rapid response. Furthermore, the precise temperature control strategy based on VCU avoids continuous energy consumption, significantly improves the utilization efficiency of the limited on-board electrical energy of new energy commercial vehicles, and achieves a balance between energy saving and safety.

Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.
[0022] It should be noted that the terms "first," "second," etc., in the specification, claims, and accompanying drawings of this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that the embodiments of this application described herein can be implemented in orders other than those illustrated or described herein. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion; for example, a process, method, system, product, or apparatus that comprises a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such processes, methods, products, or apparatus.
[0023] like Figure 1As shown in the embodiment of this application, an air compressor pipeline system for air-brake new energy commercial vehicles is provided, including: The dryer intake pipe 1 has an electric heating wire installed on its inner or outer surface; an ambient temperature sensor 5 is used to detect the ambient temperature; a vehicle control unit (VCU) 6 is electrically connected to the ambient temperature sensor 5 to receive temperature signals; a relay 7 has its control coil electrically connected to the control output terminal of the VCU 6; and a heating harness branch 8 is connected between the load contact of the relay 7 and the electric heating wire to supply power to the electric heating wire.
[0024] By integrating the electric heating wire into the dryer's air inlet pipe 1 and forming a closed-loop automatic control system with the ambient temperature sensor 5, VCU 6, and relay 7, significant benefits have been achieved. This system can automatically start and stop heating based on changes in ambient temperature, enabling proactive and intelligent prevention of pipe icing and fundamentally eliminating the major safety hazard of insufficient brake system air pressure caused by pipe ice blockage. Its highly integrated structural design not only improves the system's reliability and durability, avoiding the installation and maintenance issues of external heating devices, but also directly heats the pipes, resulting in high heat transfer efficiency and rapid response. Furthermore, the precise temperature control strategy based on VCU 6 avoids continuous energy consumption, significantly improving the utilization efficiency of the limited onboard electrical energy of new energy commercial vehicles, achieving a balance between energy saving and safety.
[0025] As an optional implementation, the electric heating wire is made of copper and is fixed to the wall of the dryer inlet pipe 1 by spiral winding or straight embedding.
[0026] The electric heating wire was further specified as being made of copper and fixed using either spiral winding or straight embedding. This specific setup not only optimizes heat conduction efficiency and ensures uniform heating of the pipeline, avoiding localized overheating or heating dead zones, but its robust fixing method also enhances its long-term reliability and durability under vehicle vibration environments, thereby guaranteeing the stability and continuity of the anti-icing effect.
[0027] As an optional implementation, the end of the dryer inlet pipe 1 is provided with a heating harness connector to enable pluggable electrical connection between the heating harness branch 8 and the electric heating wire.
[0028] Standardizing and modularizing the connection methods of the heating harness and piping allows the dryer inlet pipe 1 assembly to exist as an independent, easily replaceable component. This significantly simplifies production assembly and after-sales maintenance processes. If a fault occurs in the piping or heating components, the entire assembly can be replaced directly, reducing maintenance costs and time, and improving product maintainability and economy.
[0029] As an optional implementation, the system further includes a spiral cooling pipeline 2 and a high-temperature hose 3, wherein the dryer inlet pipe 1 is connected to the air compressor storage pipe 4 through the high-temperature hose 3.
[0030] As an optional implementation, the VCU 6 is pre-configured with a first temperature threshold and a second temperature threshold. When the temperature detected by the ambient temperature sensor 5 is lower than the first temperature threshold, the VCU 6 controls the relay 7 to engage to turn on the heating circuit; when the detected temperature is higher than the second temperature threshold, the VCU 6 controls the relay 7 to disengage to stop heating.
[0031] As an optional implementation, the first temperature threshold is -10°C and the second temperature threshold is 0°C.
[0032] As an optional implementation, the resistance value of the electric heating wire is matched with the power supply voltage so that the heating temperature of the air inlet pipe 1 of the dryer is kept constant below 10°C when energized.
[0033] As an optional implementation, the electric heating wire is a copper wire covered with an insulating layer.
