Description

Technical Field

[0001] This utility model relates to the field of vehicle temperature control, and more specifically to a temperature regulation device for a test flight vehicle used in aircraft. This utility model also relates to a test flight vehicle. Background Technology

[0002] A flight test vehicle is a special vehicle used for aircraft flight test support work, equipped with a variety of special functions and professional equipment to serve flight test missions. The flight test vehicle includes a work box that integrates all the special functions and professional equipment, and a cockpit that serves as the core control area during the vehicle's movement.

[0003] In existing test flight vehicles, the work compartment is separate from the cockpit. After arriving at the designated location, personnel work inside the work compartment, while the driver remains in the cockpit. The work compartment is equipped with air conditioning to regulate its temperature. In extreme weather conditions such as summer or winter, the temperature inside the work compartment can be regulated by this air conditioner. The driver in the cockpit needs to keep the vehicle idling to operate the air conditioning in the cockpit to maintain a comfortable temperature. However, idling increases fuel consumption, and incomplete combustion produces more harmful gases, exacerbating environmental pollution. It also easily leads to carbon buildup, which can clog fuel injectors, intake manifolds, and exhaust systems, affecting engine performance and fuel economy. Furthermore, prolonged idling accelerates engine wear and aging, and high temperatures shorten engine life and may also damage vehicle electronic systems and the catalytic converter.

[0004] Therefore, it is desirable to propose an alternative means of regulating the temperature inside the cockpit of a test vehicle that can avoid engine wear, increased fuel consumption, and decreased engine performance caused by vehicle idling, and can also reduce emissions. Utility Model Content

[0005] This invention is made to solve the above-mentioned problems in the prior art. Its purpose is to provide a temperature regulation device for a test vehicle. This temperature regulation device can transmit the air regulated by the air conditioner inside the working box to the cockpit, so as to ensure that the driver in the cockpit can maintain a relatively comfortable environment even without starting the vehicle's engine.

[0006] To achieve the above objectives, this utility model provides a temperature regulation device for a test flight vehicle. The test flight vehicle includes a working box, a cockpit, and an air conditioner for regulating the ambient temperature inside the working box. The working box and the cockpit are separate. The temperature regulation device for the test flight vehicle includes an external air pipe. One end of the external air pipe is fixed to the working box, and the other end of the external air pipe is fixed to the cockpit. The external air pipe connects the gas inside the working box with the gas inside the cockpit.

[0007] As described above, the temperature regulation device of this utility model, by using an external air pipe as a connecting device, enables gas communication between the working box of the test vehicle and the cockpit, allowing the driver to have a relatively comfortable environment in the cockpit even without starting the vehicle's engine to start the air conditioner, thus avoiding the problems caused by the vehicle idling to start the air conditioner in the cockpit.

[0008] According to one embodiment of the present invention, the external air pipe includes an airflow pipe, one end of which leads into the cockpit, and the other end of which leads into the working box and is connected to the ventilation mechanism. The ventilation mechanism is fixed inside the working box and can draw air from inside the working box into the airflow pipe.

[0009] Therefore, the temperature regulation device of this utility model combines the airflow duct with the ventilation mechanism. The ventilation mechanism draws out the cold and warm air generated by the air conditioner inside the working box and forces the gas into the external air pipe, thereby more effectively transmitting the air regulated by the air conditioner inside the working box to the cockpit.

[0010] Furthermore, the airflow duct of the temperature regulating device according to this utility model is flexible. The flexible airflow duct has good bending properties, which prevents the shaking generated during vehicle operation from damaging the duct body, and also avoids damage to the duct body caused by relative position changes and angular deflections between the cab and the work box during operation.

[0011] Preferably, the airflow duct of the temperature regulating device according to this utility model is a double-layer duct. The double-layer duct design effectively reduces the heat transfer caused by gas contact with the external environment during transmission in the airflow duct, thereby reducing energy loss and minimizing the possibility that the temperature-regulated cold or warm air transmitted from the working chamber will not heat up or cool down during the transmission of the airflow duct to the cockpit.

[0012] Specifically, the double-layered airflow duct includes a metal outer tube and a plastic inner tube, with the plastic inner tube fixed to the inner wall of the metal outer tube. Metal materials offer good corrosion resistance to the external environment, providing better protection when the test vehicle is used in extreme test flight environments. The plastic material offers good heat insulation and moisture resistance, effectively isolating outdoor air from the air inside the airflow duct.

[0013] Preferably, the outer metal tube in the airflow duct of the double-layered pipeline is designed as a corrugated pipe. The corrugated outer tube can better cope with vibrations caused by possible swaying during the operation of the test vehicle, thereby reducing vibration; on the other hand, it can also adapt to the aforementioned possible swaying and other possible relative rotations and / or displacements between the working box and the corrugated pipe through its own elastic deformation.

[0014] Furthermore, the ventilation mechanism includes a fan and a pipe fixing component. One end of the pipe fixing component is connected to the air outlet of the fan, and the other end of the pipe fixing component is connected to the inlet of the airflow pipe, allowing the air drawn in by the fan to flow into the airflow pipe. The pipe fixing component enables a stable connection between the fan and the airflow pipe, and also fixes the airflow pipe to the working housing through the cooperation of the pipe fixing component with the working housing.

[0015] In a non-limiting embodiment of this utility model, the working chamber has an opening at its end wall, and a pipe fastener is configured to pass through this opening to connect the inlet of the airflow pipe and the fan. A sealant is applied between the opening at the end wall and the surface of the pipe fastener. The sealant effectively achieves an airtight seal between the working chamber and the pipe fastener, preventing gas inside the working chamber from escaping through the gap between the inner circumferential surface of the opening and the outer wall of the pipe fastener, and also preventing external ambient air from entering the working chamber through the aforementioned gap, thereby ensuring the internal temperature of the working chamber.

[0016] Optionally, the pipe fastener is fixed to the working housing by bolts. Thus, the pipe fastener enables a detachable connection between the airflow pipe and the working housing.

[0017] According to another aspect of this utility model, a test flight vehicle is also proposed. The test flight vehicle includes a work box, a cockpit, an air conditioner for regulating the ambient temperature inside the work box, and a temperature regulation device for the test flight vehicle according to any of the above embodiments.

[0018] Based on the above-described configuration, compared with existing test vehicles, the test vehicle using the temperature regulation device proposed in this utility model can transmit the cold or warm air regulated by the air conditioning unit in the working box to the cockpit through the airflow pipe and ventilation mechanism in the external air pipe, so that even after the vehicle is turned off, the driver in the cockpit can have a good temperature environment.

[0037] The specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. These embodiments will help those skilled in the art to further understand this utility model, but are not intended to unnecessarily limit the scope of protection of this utility model.

[0038] Figure 1 This is a schematic perspective view of a test vehicle including the temperature control device for a test vehicle according to the present invention. Figure 1 As shown, the test vehicle includes a working housing 1, an air conditioner for regulating the ambient temperature inside the working housing 1, an external air pipe 3 serving as the temperature control device for the test vehicle, and a cockpit 4. The working housing 1 is fixed to the top of the main beam of the test vehicle. The air conditioner for regulating the ambient temperature inside the working housing 1 includes an outdoor unit 2 located outside the working housing 1 and a wall-mounted unit located inside the working housing 1. One end of the external air pipe 3 is fixed to the working housing 1 and extends into the working housing 1, while the other end of the external air pipe 3 is fixed to the cockpit 4 and extends into the cockpit 4, thus connecting the air inside the working housing 1 and the cockpit 4.

[0039] Once the test vehicle reaches the designated location, personnel begin work inside the work compartment 1. At this time, the air conditioning unit in work compartment 1 is powered by an independent power source and operates to regulate the air temperature inside. The driver of the test vehicle remains in the cockpit 4. The external air pipe 3 of the temperature regulation device can transfer either the cool air generated by the air conditioning unit in work compartment 1 or the warm air generated by the heating unit to the cockpit 4, ensuring a comfortable temperature environment in both work compartment 1 and cockpit 4 even when the test vehicle's engine is off.

[0040] like Figure 2 As shown, the external air pipe 3 includes an airflow duct 5 and a ventilation mechanism 6. One end of the airflow duct 5 is inserted into the cockpit 4, and the other end of the airflow duct 5 is connected to the ventilation mechanism 6, which is fixed to the inner wall of the working box 1.

[0041] In this embodiment, the airflow duct 5 is implemented as a flexible hose, which has good flexibility and can prevent damage to the duct body caused by shaking when the vehicle is moving. During the movement of the test vehicle, there may be relative position changes and angular deflections between the cockpit and the work box. The flexible hose with good flexibility can also prevent damage to the duct body caused by such relative position changes and angular deflections.

[0042] Preferably, in the illustrated embodiment, the airflow duct 5 is implemented as a double-layer duct. The airflow duct 5 includes a metal outer tube 51, an air inlet 52, an air outlet 53, and a plastic inner tube 54. The air inlet 52 and the air outlet 53 are respectively located at the two ends of the metal outer tube 51. The plastic inner tube 54 is fixed to the inner wall of the metal outer tube 51, so that there is no gap between the outer circumferential surface of the plastic inner tube 54 and the inner circumferential surface of the metal outer tube 51. During airflow transmission, the double-layer design of the metal outer tube 51 and the plastic inner tube 54 can reduce the temperature change of the airflow caused by heat exchange with the outside environment during transmission. In addition, the test vehicle will be used in some extreme test flight environments. The metal material of the metal outer tube 51 has good corrosion resistance to the external environment, while the plastic material of the plastic inner tube 54 has good heat insulation and moisture resistance, which can better isolate the outdoor environment around the test vehicle from the air inside the airflow duct 5, reducing energy loss during airflow transmission. Both the outer metal tube 51 and the inner plastic tube 54 are constructed using flexible hoses. Their good flexibility prevents damage from vibrations during vehicle operation. In the illustrated embodiment, the outer metal tube 51 is constructed as a corrugated pipe. This corrugated design allows for vibration damping during the operation or travel of the test vehicle, and also accommodates potential changes in the relative angle and / or displacement between the work box 1 and the cockpit 4 during operation, preventing damage to the airflow duct 5. Such damage affects the transmission of temperature-regulated air between the work box 1 and the cockpit 4, thus impacting the temperature regulation efficiency of the temperature control device, reducing the comfort level within the cockpit 4, and causing the temperature-regulated air to dissipate, resulting in energy waste.

[0043] Alternatively, the airflow duct 5 can also be a multi-layered pipe structure with an insulation layer on the outside of a metal pipe, and is not limited to the double-layered pipe structure with a metal outer pipe and a plastic inner pipe shown in this embodiment.

[0044] The ventilation mechanism 6 includes a fan 61, a pipe fastener 62, and sealant 63. One end of the pipe fastener 62 is connected to the air outlet of the fan 61, while the other end is connected to the air inlet 52 of the airflow duct 5. The pipe fastener 62 is threadedly connected to the fan 61 and the air inlet 52, and the fastening and connection between the pipe fastener 62 and both are achieved through the mutual engagement of the internal and external threads. At the front end of the working housing 1, i.e., Figure 1A circular opening is provided on the end wall of the working housing 1 near the cockpit 4. A pipe fastener 62 is inserted into this circular opening. The flanges at both ends of the pipe fastener 62 are detachable. When installed into the working housing 1, the main body of the pipe fastener 62 passes through the circular opening on the side wall of the working housing 1. Then, the flanges at both ends engage with the main body and abut against the side wall of the working housing 1. The pipe fastener 62 is then secured to the side wall of the working housing 1 with bolts. Sealant 63 is wrapped around the circumferential surface of the main body of the pipe fastener 62 to fill the gap between the pipe fastener 62 and the inner wall of the circular opening, thereby reducing or preventing the air regulated by the air conditioning inside the working housing 1 from escaping to the outside of the working housing 1 through the aforementioned gap. The fan 61 can draw out the cold and warm air generated by the air conditioning unit inside the working box 1, and the drawn cold and warm air can be transmitted to the interior of the cockpit 4 through the airflow duct 5, thereby regulating the ambient temperature inside the cockpit 4 without starting the air conditioning in the cockpit 4. Thus, even without starting the engine of the test vehicle, a relatively comfortable environment can be provided for the driver in the cockpit 4.

[0045] When using this temperature control device, the air conditioning unit of the test vehicle's working compartment 1 is powered by an external power source on-site. The air conditioning unit regulates the temperature of the air inside the working compartment 1. Simultaneously, the fan 61 of the ventilation mechanism 6 is also powered by an external power source, blowing the temperature-regulated air from the working compartment 1 into the cockpit 4 through the airflow duct 5. The airflow volume through the airflow duct 5 can be adjusted by changing the opening and closing of the fan blades in the fan 61 as needed. Therefore, the driver in the cockpit 4 does not need to start the test vehicle's engine to drive the air conditioning unit inside the cockpit 4. The external air pipe 3 connects the working compartment 1 and the cockpit 4, maintaining a consistent internal temperature. This reduces exhaust fumes generated during vehicle idling due to the need to start the air conditioning unit in the cockpit 4, reduces fuel consumption during idling, avoids engine performance degradation caused by prolonged idling, improves the utilization efficiency of the air conditioning unit in the working compartment 1, and reduces environmental pollution.

Those skilled in the art can make various suitable changes or modifications to these embodiments without departing from the scope of protection of the claims of this utility model, but all such changes and modifications fall within the protection scope of this utility model.

[0047] For example, in the embodiment described above, the seal between the pipe fastener 62 and the circular opening at the front end wall of the working box 1 is achieved by sealant 63. However, the present invention is not limited to this and airtight seal between the two can also be achieved in other ways, such as by setting a sealing gasket.

[0048] Furthermore, the position of the temperature regulation device for the test vehicle of this utility model in the test vehicle is not limited to the position shown in the figure. It can also be arranged on the right side or the lower part of the end wall at the front end of the working box of the test vehicle.

[0049] Furthermore, the airflow duct 5 in the temperature control device for test vehicles of this invention can be composed of multiple interconnected duct segments connected by pipe connectors such as flanges, and is not limited to this. Figures 1 to 3 The embodiment shown consists of only one complete pipe section.
