Description
Technical Field
[0001] This utility model relates to the application field of mobile vehicle-mounted compressed gas, specifically to a compression device for a vehicle-mounted shared power system. Background Technology
[0002] Compressed gas has a wide range of applications. With the advancement of industrial and other technologies, its application scenarios are expanding. The use of compressed gas in vehicles is gradually increasing, including applications such as field operations and temporary short-term gas use. There are also many sub-sectors where compressed air is used as a pneumatic power source and a source of raw gas. Vehicle-mounted gas use has become a new growth point.
[0003] Initially, the solution for onboard gas supply was to use onboard bottled gas. However, this method had limitations, such as limited bottled gas capacity, the fact that bottled gas is a high-pressure specialized device, and the cumbersome process of transporting and changing cylinders. This led to the development of onboard compressed gas solutions. Early onboard compressed gas systems used a separate onboard diesel engine to power the compressor, producing compressed gas. This required a separate diesel engine, resulting in a high-powered onboard generator; it also increased the space occupied by the additional equipment; and it added the need for regular maintenance and upkeep. Utility Model Content
[0004] The purpose of this utility model is to provide a compression device for a vehicle-mounted shared power system. This device solves the technical problems of large space occupation, high energy consumption and complex maintenance in traditional vehicle-mounted compressed gas supply solutions by optimizing power distribution and structure.
[0005] To achieve the above objectives, this utility model is implemented through the following technical solution:
[0006] A compression device for a vehicle-mounted shared power system includes:
[0007] Car engine;
[0008] A shift switch, which switches the power output path of the vehicle engine via a clutch;
[0009] The power output path includes:
[0010] First path: The clutch is connected to the vehicle's side transmission gear to drive the vehicle;
[0011] Second path: The clutch is connected to the engine drive shaft to drive the compressor assembly and / or generator assembly.
[0012] In this solution, the car engine can quickly switch between two modes through the linkage control of the shift switch and the clutch. The first path directly drives the vehicle, while the second path distributes power to the compressor or generator to meet the needs of compressed gas production or power generation when the vehicle is parked. Compared with the existing technology, this device omits the traditional independent diesel engine and uses the existing car power system to achieve "one machine for multiple uses", which significantly reduces the number of on-board equipment, space occupation and maintenance costs.
[0013] As a further technical solution for the compression device, the compression device also includes a two-way clutch and a control system;
[0014] The bidirectional clutch is synchronously rotatably connected to the engine drive shaft, and the bidirectional clutch is engaged with the compressor assembly and / or the generator assembly respectively;
[0015] The control system controls the engagement state of the bidirectional clutch based on the switching signal of the switching switch.
[0016] In this solution, the two-way clutch acts as a mechanical hub, rotating synchronously with the engine drive shaft. It can selectively transmit power to the compressor or generator, or drive both simultaneously, according to the control system. This achieves dynamic distribution and precise control of engine power between the compressor and generator. When the control system receives the switching switch signal in real time and adjusts the engagement state of the two-way clutch, it achieves rapid response of the power path, avoids mechanical conflict or energy loss, and optimizes energy efficiency through dynamic load management, enabling the engine to operate under optimal conditions, reducing fuel consumption and extending equipment life. Ultimately, this achieves intelligent upgrading and efficient resource utilization of the vehicle power system.
[0017] As a further technical solution for the compression device, when only the compressor assembly is driven, the compressed air in the automobile cylinder supplies air to the compressor-side cylinder in the compressor assembly, so that the bidirectional clutch remains connected to the compressor gearbox in the compressor assembly and outputs power.
[0018] In this solution, when the system only needs to drive the compressor, the compressed air in the car cylinder directly supplies air to the compressor-side cylinder. The air pressure drives the two-way clutch to rigidly connect with the compressor gearbox, ensuring that the engine power is efficiently transmitted to the compressor and avoiding idling losses. At the same time, the compressed air of the car itself is used as the execution medium to form a "gas production-gas consumption" energy closed loop, reducing energy consumption and simplifying pipeline design.
[0019] As a further technical solution for the compression device, the compressor assembly also includes a compressor shaft-side drive gear, a compressor shaft-side drive coupling, a compressor shaft-side passive coupling, a compressor head shaft, and a compressor-side speed sensor;
[0020] The compressor gearbox transmits power to the compressor shaft-side drive gear, which in turn transmits power to the compressor shaft-side drive coupling. The compressor shaft-side drive coupling then transmits power to the compressor shaft-side passive coupling, ultimately transmitting power to the compressor head shaft, thus powering the compressor and generating compressed air.
[0021] The compressor-side speed sensor detects the rotational speed of the compressor head shaft and feeds the signal back to the control system.
[0022] In this scheme, the compressor gearbox transmits power to the compressor head shaft in sequence through the compressor shaft-side drive gear, compressor-side drive coupling, and driven coupling, enabling the compressor to generate compressed air. At the same time, the compressor-side speed sensor detects the compressor head shaft speed and feeds the signal back to the control system, which helps the control system to monitor the compressor's operating status in real time and make dynamic adjustments based on the speed, ensuring that the compressor operates stably and efficiently under different operating conditions.
[0023] As a further technical solution for the compression device, when only the generator assembly is driven, the compressed air in the automobile cylinder supplies air to the engine-side cylinder in the generator assembly, so that the bidirectional clutch remains connected to the generator gearbox in the generator assembly and outputs power.
[0024] In this solution, when the system only needs to drive the generator, the compressed air in the car cylinder directly supplies air to the generator-side cylinder. The air pressure drives the two-way clutch to rigidly connect with the generator gearbox, ensuring that the engine power is efficiently transmitted to the generator to meet the power generation needs. At the same time, the compressed air of the car itself is used as the execution medium to form a "gas production-electricity consumption" energy closed loop, reducing energy consumption and simplifying pipeline design.
[0025] As a further technical solution for the compression device, the generator assembly includes a generator shaft-side passive coupling, a generator shaft-side active coupling, a generator shaft-side active gear, and a generator-side speed sensor;
[0026] The generator gearbox transmits power to the generator shaft-side drive gear, which in turn transmits power to the generator shaft-side drive coupling. The generator shaft-side drive coupling then transmits power to the generator shaft-side passive coupling, enabling the generator to operate normally and provide the required power.
[0027] The generator-side speed sensor detects the speed of the passive coupling on the generator shaft side and feeds the signal back to the control system.
[0028] In this scheme, the generator gearbox transmits power to the generator sequentially through the generator shaft-side drive gear, drive coupling, and driven coupling, enabling the generator to operate normally and provide the required power. At the same time, the generator-side speed sensor detects the speed of the generator shaft-side driven coupling and feeds back the signal to the control system. This helps the control system to monitor the generator's operating status in real time and dynamically adjust the generator's operating status according to the speed, ensuring that the generator provides stable and efficient power under different operating conditions.
[0029] As a further technical solution for the compression device, when the compressor assembly and the generator assembly are driven simultaneously, the compressed air in the automobile cylinder simultaneously supplies air to the compressor-side cylinder in the compressor assembly and the engine-side cylinder in the generator assembly, and the bidirectional clutch simultaneously engages the compressor gearbox in the compressor assembly and the engine gearbox in the generator assembly.
[0030] In this solution, when the system needs to supply air and generate electricity simultaneously, the compressed air in the car cylinder supplies air to the compressor-side cylinder and the generator-side cylinder respectively. The air pressure drives the two-way clutch to rigidly connect with the two gearboxes at the same time, so that the engine power is synchronously transmitted to the compressor and generator through the drive shaft, which meets the dual load operation requirements. By sharing the power source, "one machine for multiple uses" is achieved, avoiding equipment redundancy and energy waste in the traditional independent drive mode.
[0031] As a further technical solution for the compression device, pressure sensors are respectively provided for the compressor-side cylinder and the engine-side cylinder. The control system performs pressure detection based on the pressure sensors. If the pressure is lower than the required pressure of the compressor-side cylinder or the engine-side cylinder, an alarm signal will be issued until the alarm signal is cleared.
[0032] In this solution, the control system dynamically detects the pressure value inside the cylinder through a pressure sensor. When the pressure in any cylinder is lower than the threshold required for clutch engagement, an alarm signal is immediately triggered to alert the user or automatically start the air replenishment process. This ensures that the two-way clutch completes power transmission under stable air pressure, avoiding clutch slippage, power interruption, or mechanical damage caused by insufficient air pressure.
[0033] As a further technical solution for the compression device, the compression device also includes a housing, which is a sealed structure. The housing integrates the compressor gearbox, the generator gearbox, and the bidirectional clutch, and is connected to the automobile engine via a coupling.
[0034] In this solution, the sealed structure of the enclosure effectively isolates external dust, moisture and other pollutants, ensuring that the transmission components operate in a clean environment, extending the equipment's lifespan. The internal integrated layout significantly shortens the power transmission path, reduces energy loss and improves transmission efficiency.
[0035] As a further technical solution for the compression device, the control system dynamically adjusts the transmission ratio of the compressor gearbox and the generator gearbox based on the feedback signals from the compressor-side speed sensor and the generator-side speed sensor.
[0036] In this solution, the control system automatically adjusts the gearbox transmission ratio based on the speed feedback signal and the actual load requirements of the compressor and generator, so that the engine output speed is precisely matched with the equipment operating requirements, avoiding power waste or overload risk caused by a fixed transmission ratio. This adaptive adjustment mechanism not only improves the efficiency of compressed air production and power generation, but also reduces fuel consumption by optimizing engine operating conditions, while ensuring that the equipment can operate stably under high or low load conditions.
[0037] Compared with the prior art, this utility model has the following advantages and beneficial effects:
[0038] 1. This utility model achieves "one machine for multiple uses" by sharing the power of a car engine to replace the traditional independent diesel engine. The engine can be flexibly switched to drive the vehicle, supply air to the compressor, or generate electricity from the generator, which significantly reduces the number of on-board devices and energy consumption. It is especially suitable for scenarios where air supply or power generation is required after parking, thereby reducing fuel consumption and operating costs.
[0039] 2. The control system of this utility model monitors the cylinder pressure in real time through a pressure sensor and dynamically adjusts the transmission ratio in combination with speed feedback to ensure that the compressor and generator operate under optimal conditions. When the air pressure is insufficient, an alarm is triggered to avoid mechanical failure. At the same time, the adaptive speed adjustment also improves the power transmission efficiency and extends the equipment life. Attached Figure Description

Detailed Implementation
[0044] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the embodiments and accompanying drawings. The illustrative embodiments and descriptions of this utility model are only used to explain this utility model and are not intended to limit this utility model.
[0045] Example 1
[0046] This embodiment 1 provides a compression device for a vehicle-mounted shared power system, such as... Figure 1 As shown, it includes a compressor assembly, a generator assembly, an automotive engine 1, a shift switch 3, a two-way clutch 17, and a control system 23;
[0047] Among them, the car engine 1 serves as a shared power source, connected to the clutch 2 via the output shaft, and the shift switch 3 switches the power output path of the car engine 1 through the clutch 2 to provide the power required for vehicle driving, compressor assembly air supply, or generator assembly power generation.
[0048] Specifically, the car engine 1 is connected to the clutch 2 via the output shaft. The shift switch 3 controls the selection of the power output path of the clutch 2 via mechanical or electronic signals. Here, the clutch 2 is a multi-plate friction clutch, and the engagement and disengagement of the path are controlled by air pressure or hydraulic pressure. The power output path includes a first path and a second path. The first path is for the shift switch 3 to select the clutch 2 to maintain connection with the car side transmission gear 4 for driving the car. The second path is for the shift switch 3 to select the clutch 2 to maintain contact with the engine drive shaft 12 and provide power.
[0049] In this embodiment, one end of the engine drive shaft 12 is connected to the clutch 2 via a coupling 5, and the other end of the engine drive shaft 12 is connected to a two-way clutch 17. The two-way clutch 17 rotates synchronously with the engine drive shaft 12. Through the two-way clutch 17, the power of the engine drive shaft 12 can be transmitted to the compressor assembly or the generator assembly, or simultaneously to both the compressor assembly and the generator assembly.
[0050] Please refer to Figure 1 As shown, when the shift switch 3 selects the clutch 2 to maintain connection with the engine drive shaft 12 and provide power, the control system 23 controls the engagement state of the bidirectional clutch 17 according to the shift signal of the shift switch 3, and determines whether to provide power to the compressor assembly, the generator assembly, or both the generator assembly and the compressor assembly at the same time.
[0051] When only the compressor assembly is driven, the compressed air in the car cylinder supplies air to the compressor-side cylinder 18 in the compressor assembly, keeping the two-way clutch 17 connected to the compressor gearbox 11 in the compressor assembly and outputting power. The compressor gearbox 11 transmits power to the compressor head shaft 10 in sequence through the compressor shaft-side drive gear 7, the compressor-side drive coupling 8, and the compressor-side passive coupling 9. The compressor head shaft 10 enables the compressor to obtain power and generate compressed air.
[0052] Meanwhile, a compressor-side speed sensor 21 is also connected to the compressor head shaft 10. The compressor-side speed sensor 21 detects the speed of the compressor head shaft 10 and feeds the signal back to the control system 23. The control system 23 makes dynamic adjustments according to the speed.
[0053] When only the generator assembly is driven, the compressed air in the car cylinder supplies air to the engine-side cylinder 19 in the generator assembly, keeping the two-way clutch 17 connected to the generator gearbox 16 in the generator assembly and outputting power. The generator gearbox 11 then transmits power to the generator in sequence through the generator shaft-side drive gear 15, the generator shaft-side drive coupling 14, and the generator shaft-side passive coupling 13, enabling the generator to work normally and provide the required power.
[0054] Meanwhile, a generator-side speed sensor 22 is connected to the generator shaft-side passive coupling 13. The generator-side speed sensor 22 detects the speed of the generator shaft-side passive coupling 13 and feeds back the signal to the control system 23. The control system 23 can dynamically adjust the working state of the generator according to the speed.
[0055] When the compressor assembly and generator assembly are driven simultaneously, compressed air in the vehicle cylinders simultaneously supplies air to the compressor-side cylinder 18 of the compressor assembly and the engine-side cylinder 19 of the generator assembly. The two-way clutch 17 simultaneously engages the compressor gearbox 11 of the compressor assembly and the engine gearbox 16 of the generator assembly.
[0056] Meanwhile, since the bidirectional clutch 17 is a pneumatic clutch, it achieves rapid engagement and disengagement through the air pressure difference between the compressor-side cylinder 18 and the generator-side cylinder 19. Therefore, pressure sensors 20 are connected to the compressor-side cylinder 18 and the generator-side cylinder 19 respectively. The control system 23 detects the pressure based on the pressure sensors 20. If the pressure is lower than the required pressure of the compressor-side cylinder 18 or the generator-side cylinder 19, an alarm signal will be issued to remind the user or automatically start the air replenishment process to ensure that the bidirectional clutch 17 completes power transmission under stable air pressure, avoiding clutch slippage, power interruption or mechanical damage caused by insufficient air pressure.
[0057] In summary, this embodiment allows the vehicle engine 1 to quickly switch between two modes through the linkage control of the shift switch 3 and the clutch 2. The first path directly drives the vehicle, while the second path distributes power to the compressor or generator to meet the needs of compressed gas production or power generation when the vehicle is parked. Furthermore, this embodiment omits the traditional independent diesel engine and utilizes the existing vehicle power system to achieve "one machine for multiple uses," significantly reducing the number of onboard devices, space occupation, and maintenance costs.

[0059] This embodiment 2 provides a compression device for a vehicle-mounted shared power system based on embodiment 1, such as... Figure 1 As shown, the compression device also includes a housing 6, which is a sealed structure. Inside the housing 6, the compressor gearbox 11, the generator gearbox 16, and the two-way clutch 17 are integrated, and it is connected to the automobile engine 1 through the coupling 5. The sealed structure of the housing effectively isolates external dust, water vapor and other pollutants, ensuring that the transmission components operate in a clean environment and extending the equipment life.
[0060] Example 3
[0061] This embodiment 3 provides a compression device for a vehicle-mounted shared power system based on embodiment 1 or embodiment 2, such as... Figure 1 As shown, the control system 23 can also automatically adjust the gearbox transmission ratio based on the speed feedback signal and the actual load requirements of the compressor and generator, so that the engine output speed is precisely matched with the equipment operation requirements, avoiding power waste or overload risk caused by a fixed transmission ratio.
[0062] The specific embodiments described above omit some standard configurations such as bearings, retaining rings, shaft seals, keys, lubricating oil, and automotive tachometers. Since these are all standard configurations, they have been omitted from the patent drawings and the foregoing description. However, the protective effect of this utility model (invention patent) should not be weakened as a result.
