Description

Technical Field

[0001] This utility model relates to the field of vehicle auxiliary equipment technology, and in particular to a vehicle-mounted air circuit function expansion module. Background Technology

[0002] As commercial vehicles become increasingly feature-rich, the tasks of the vehicle's air circuit system are gradually increasing. In addition to basic braking and door control operations, seat adjustment, horn activation, and cleaning and dust removal equipment inside and outside the driver's cab all require a stable air supply. The number of air circuit interfaces reserved at the factory is limited and cannot directly meet the needs of later installation of various pneumatic devices, resulting in a shortage of air supply interfaces when the vehicle is upgraded.

[0003] Currently, when expanding or modifying the vehicle's air circuit, a simple three-way fitting or hose is often used to directly connect the air circuit from the original vehicle's air tank. This non-integrated connection method lacks a stable mechanical support structure. The external pipe is prone to loosening or even falling off under the continuous vibration of the vehicle during driving, which can lead to air leakage and affect driving safety. Moreover, this simple connection method does not have air pressure buffering and stabilization functions, causing the pressure of the expanded air circuit to fluctuate significantly with the original vehicle system. It cannot provide stable working pressure for precision pneumatic equipment, and the lack of real-time monitoring of the air circuit status also makes it difficult for the driver to detect potential air circuit abnormalities.

[0004] Therefore, this utility model proposes an on-board air circuit function expansion module to overcome the shortcomings of the prior art. Utility Model Content

[0005] In view of the problems existing in the vehicle air circuit system when expanding its functions, such as insufficient number of interfaces, non-integrated pipeline connection method leading to poor vibration resistance and easy loosening and leakage, lack of pressure stabilization and buffer mechanism leading to unstable air supply pressure, and lack of real-time status monitoring means that faults are difficult to detect in a timely manner, this utility model aims to provide a vehicle air circuit function expansion module with improved structure that can effectively solve the above problems.

[0006] This utility model provides a vehicle-mounted air circuit function expansion module, including: a module housing, a control mechanism disposed inside the module housing, and a connection mechanism disposed on the module housing.

[0007] The connecting mechanism is used to connect the module housing with the vehicle's air circuit system and expand its functions. The connecting mechanism includes a connecting rod, a flange connecting ring, and expansion bolts. One end of the connecting rod is fixedly connected to the module housing, and the other end connects to the flange connecting ring. The connecting rod is used to ensure force transmission and structural stability. The flange connecting ring has a connecting hole for precise positioning. The expansion bolts, in conjunction with the connecting hole, securely mount the flange connecting ring to the vehicle mounting surface. The module housing has an air circuit channel inside, which is connected to the original vehicle's air circuit through the sealing structure of the connecting mechanism. The flange connecting ring is used to enhance the sealing performance at the connection point. The control mechanism, as the core coordinating working component, is built into the module housing. It is used to dynamically adjust the air circuit parameters according to sensor data and operating commands to achieve stable expansion and precise control of the vehicle's air circuit functions.

[0008] Preferably, the control mechanism includes a pressure-stabilizing gas storage tank, which is fixedly installed inside the module housing. The gas inlet of the pressure-stabilizing gas storage tank is connected to the gas passage inside the module housing. The pressure-stabilizing gas storage tank uses its internal volume to smooth and buffer the pressure fluctuations of the incoming gas, thereby storing and stabilizing the gas pressure and providing a stable gas source for subsequent gas-using equipment.

[0009] Preferably, the control mechanism also includes a branch gas pipeline, which is connected to the outlet of the pressure-stabilized gas storage tank. The branch gas pipeline extends to the outside of the module housing and serves as an airflow distribution channel to accurately distribute the gas processed by the pressure-stabilized gas storage tank to various gas-using components on the vehicle, meeting the needs of multiple devices using gas simultaneously.

[0010] Preferably, a temperature sensor is installed on the branch gas pipeline. The temperature sensor is electrically connected to the control mechanism and directly contacts the airflow. It is used to monitor the gas pipeline temperature data in real time and feed it back to the control mechanism so that the control mechanism can make corresponding adjustment strategies according to the temperature changes.

[0011] Preferably, the control mechanism also includes a power input interface, which is disposed on the module housing and electrically connected to the control mechanism for connecting to the vehicle power supply to provide a stable operating voltage for the electrical components within the control mechanism.

[0012] Preferably, a display screen is provided on the surface of the module housing. The display screen is electrically connected to the control mechanism. The display screen serves as a visual window for human-machine interaction, used to intuitively display the working status of relevant pressure and temperature, so that users can keep track of the operation of the gas circuit system at any time.

[0013] Preferably, the module housing surface is also provided with a button, which is located on one side of the display screen. The button is electrically connected to the control mechanism and serves as a user input terminal for the user to issue operation commands to enable or disable the pneumatic circuit function or set parameters.

[0014] Preferably, the connecting rod has a hollow structure to form an airflow channel inside the connecting mechanism. One end of the hollow structure of the connecting rod passes through the center of the flange connecting ring, and the other end is connected to the air passage inside the module housing. This hollow design allows the connecting rod to serve as a mechanical support while also functioning as an air duct, simplifying the overall structure.

[0015] This utility model has the following beneficial effects: 1. This utility model solves the problems of unstable connection, poor sealing and complicated installation of existing vehicle air circuit expansion equipment with the original vehicle by setting a connecting mechanism consisting of a connecting rod, a flange connecting ring and expansion bolts on the outer wall of the module housing. The hollow structure of the connecting rod realizes the air circuit conduction, and the flange connecting ring is fixed by multi-point locking. This achieves the effects of improving the stability of module installation, ensuring the safety of air circuit sealing and transmission, and simplifying the installation operation process.

[0016] 2. This utility model integrates a control mechanism inside the module housing, uses a pressure-stabilizing gas tank to buffer and stabilize the introduced gas, achieves multi-path distribution through branch gas pipelines, and combines temperature sensors, display screens, and buttons to realize status monitoring and interactive control. It solves the problems of existing vehicle-mounted gas circuits having single functions, lacking pressure stabilization mechanisms, and being unable to monitor the gas circuit status in real time. It achieves the effects of improving the stability of vehicle-mounted gas supply, realizing intelligent monitoring and management, and enhancing the expandability of gas circuit functions.

All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the protection scope of this utility model.

[0020] Example: Please refer to Figures 1 to 4 This utility model provides a vehicle air circuit function expansion module, which aims to solve the problems of the limited number of interfaces in the existing vehicle air circuit system, which cannot meet the air demand of multiple devices at the same time, and the loose and unstable external air circuit connection structure.

[0021] Please refer to Figure 1 and Figure 2 The vehicle-mounted air circuit function expansion module includes a module housing 1, a control mechanism 2 disposed inside the module housing 1, and a connection mechanism 3 disposed on the outer wall of the module housing 1. The module housing 1 is constructed as a hollow box structure to serve as the mounting carrier for the core components. The module housing 1 is made of rigid metal or engineering plastic to provide physical protection. The control mechanism 2, as a core functional component, is fixedly installed in the inner cavity of the module housing 1. The control mechanism 2 is used to realize gas pressure stabilization, buffering, branch distribution, and status monitoring. The connection mechanism 3, as a bridge for the physical connection between the module housing 1 and the original vehicle air circuit, is fixedly disposed on the outer surface of the module housing 1. The connection mechanism 3 is used to securely lock the module housing 1 to the vehicle mounting surface and realize the introduction of the air source. Through the cooperation of the module housing 1, the control mechanism 2, and the connection mechanism 3, the vehicle-mounted air circuit function expansion module constitutes an expansion device that integrates mechanical fixation, air circuit conduction, and intelligent control.

[0022] Please refer to Figure 3The connecting mechanism 3 includes a connecting rod 31, a flange connecting ring 32, and an expansion bolt 34. The connecting rod 31 is constructed as a hollow tubular structure with a central axial through-hole to form an internal airflow channel. One end of the connecting rod 31 is vertically welded and fixed to the outer wall of the module housing 1. The hollow inner cavity of the connecting rod 31 is connected to the air passage inside the module housing 1. The other end of the connecting rod 31 is integrally formed and fixedly connected to the end face of the flange connecting ring 32. The flange connecting ring 32 is constructed as a circular plate structure. Several connecting holes 33 are opened on the plate of the flange connecting ring 32. The connecting holes 33 are circumferentially oriented around the flange connecting ring 32. The connecting holes 33 are uniformly distributed and are through holes that penetrate the thickness direction of the flange connecting ring 32. The size of the expansion bolt 34 is adapted to the connecting holes 33. In the installation state, the flange connecting ring 32 is attached to the vehicle mounting surface. The hollow channel of the connecting rod 31 is aligned with the original vehicle air outlet. The expansion bolt 34 passes through the connecting holes 33 and is locked in the vehicle mounting surface. Through the high-strength rigid support of the connecting rod 31 and the multi-point locking cooperation of the flange connecting ring 32, the connecting mechanism 3 realizes the cantilevered and stable installation of the module housing 1. The hollow structure of the connecting rod 31 also realizes the leakage-free delivery of the original vehicle air source to the inside of the module housing 1.

[0023] In a preferred embodiment, in order to achieve pressure stabilization and buffering of the incoming gas, the control mechanism 2 includes a pressure-stabilizing gas storage tank 22. The pressure-stabilizing gas storage tank 22 is fixedly installed at the bottom of the inner cavity of the module housing 1 by a mounting bracket. The air inlet of the pressure-stabilizing gas storage tank 22 is sealed and connected to the hollow channel inside the connecting rod 31 through a pipeline. The pressure-stabilizing gas storage tank 22 uses its own volume to buffer the incoming airflow to eliminate pressure pulsation.

[0024] In a preferred embodiment, in order to achieve precise distribution of gas source to multiple gas-using devices, the control mechanism 2 also includes a branch gas pipeline 25. The input end of the branch gas pipeline 25 is connected to the gas outlet of the pressure-stabilized gas storage tank 22, and the output end of the branch gas pipeline 25 extends through the side wall of the module housing 1 to the outside of the module housing 1. The branch gas pipeline 25 is used to connect to external vehicle-mounted gas-using devices.

[0025] In a preferred embodiment, in order to monitor the temperature status of the gas path in real time, a temperature sensor 26 is installed on the branch gas path pipe 25. The sensing probe of the temperature sensor 26 is sealed and inserted into the cavity of the branch gas path pipe 25 and comes into direct contact with the airflow. The temperature sensor 26 is electrically connected to the main control circuit board of the control mechanism 2 through a signal wire.

[0026] In a preferred embodiment, in order to realize the power supply and human-machine interaction functions of the module, a power input interface 21 is embedded on the side wall surface of the module housing 1. The power input interface 21 is electrically connected to the control mechanism 2 to introduce external vehicle power. A display screen 24 is fixedly embedded on the front surface of the module housing 1. The display screen 24 is electrically connected to the control mechanism 2 to display the air pressure and temperature values. A button 23 is installed on the front surface of the module housing 1 and on one side of the display screen 24. The button 23 is electrically connected to the control mechanism 2 to allow the user to input control commands.

[0027] Working principle: When the installation is being carried out, the operator aligns the flange connecting ring 32 of the connecting mechanism 3 with the original vehicle air source interface on the vehicle mounting surface, uses the connecting hole 33 on the flange connecting ring 32 for position calibration, and screws the expansion screw 34 through the connecting hole 33 into the vehicle mounting surface until it is locked. At this time, the hollow channel inside the connecting rod 31 is sealed and connected to the original vehicle air circuit, and the module housing 1 is stably supported in the predetermined position by the connecting rod 31. When the system is powered on, the power input interface 21 introduces the vehicle power into the control mechanism 2. The gas from the original vehicle air source enters the pressure-stabilizing gas tank 22 via the connecting rod 31. The pressure-stabilizing gas tank 22 stores the gas and smooths out pressure fluctuations. The stabilized gas enters the branch gas pipeline 25 and is delivered to each gas-using terminal. During this process, the temperature sensor 26 senses the airflow temperature in real time and sends the data to the control mechanism 2. The display screen 24 displays the current temperature and pressure status in real time. The user can issue commands by observing the display screen 24 and operating the button 23. The control mechanism 2 dynamically adjusts the gas circuit parameters according to the sensor feedback and user commands, thereby realizing the expansion and stable control of the vehicle air circuit function.
