Description

TECHNICAL FIELD

[0001] The present application relates to the field of comprehensive support vehicles, in particular to a comprehensive support vehicle. BACKGROUND

[0002] The comprehensive support vehicle is a military and civilian vehicle, which has multiple functions to achieve more comprehensive and more adaptable application in terrain environment.

[0003] In actual practice, there are the following problems:

[0004] 1. The existing comprehensive support vehicle is equipped with an air conditioning device, which is different from a family car. The air conditioning device is usually external, similar to a household air conditioner outdoor unit. Then, unlike a household outdoor unit, the comprehensive support vehicle works outdoors, and the outdoor working environment is complex. In addition, the comprehensive support vehicle generally works in complex road conditions, and jolting, shaking, wind sand, etc. can affect the internal structure of the vehicle. However, due to the influence of jolting or wind sand, it is impossible to perfectly seal the entire air conditioning system, so impurities such as wind sand, jolting impact, and oxide skin will enter the refrigeration circuit. In addition, the air conditioning system is equipped with an electronic expansion valve, which has a small needle port that is easily clogged by impurities. The existing technology can only disassemble the electronic expansion valve for maintenance, which has high overall disassembly and maintenance costs and high time costs.

[0005] 2. The existing air conditioning blockage can only rely on maintenance to troubleshoot, but it cannot be used normally for a period of time before troubleshooting, causing a large waste of time cost.

[0006] 3. When the existing technology maintains the air conditioner and the electronic expansion valve is blocked, the impurities clogging the valve port of the electronic expansion valve can easily fall into the refrigeration cycle, and the impurities cannot be removed in time.

[0007] 4. When the existing air conditioning refrigerant enters the electronic expansion valve, due to the sudden reduction of the valve port path, a rotational flow will occur in the valve cavity, causing unexpected vibration or abnormal noise.

[0008] 5. The existing electronic expansion valve has a small size, and machining a through hole will reduce the overall strength and increase the cost. However, the field expects to provide more functions, so more machining is required, which is contradictory. SUMMARY

[0012] The guide sleeve is arranged below the top wall of the shell, the upper end of the valve needle is accommodated in the guide sleeve, and the rotor can drive the valve needle to rotate; the nut is fixed above the bottom wall of the shell, the valve needle extends downward through the nut, the left side of the valve body is connected with the cross connection pipe, the lower end of the valve body is provided with a surrounding part, and the surrounding part is connected to the upper end of the vertical connection pipe in a sleeved manner;

[0013] The right side of the valve body is provided with the stepped hole, the stepped hole comprises a large diameter section and a small diameter section, the plug is arranged in the large diameter section, a bypass is further arranged in the inner wall of the valve body, the bypass comprises a horizontal channel and a vertical channel, the horizontal channel communicates with the inner cavity of the valve body, the upper end of the vertical channel communicates with the horizontal channel, and the lower end of the vertical channel communicates with the small diameter section; a valve port is arranged on the valve body to accommodate the valve needle, the small diameter section communicates with the valve port, the valve port comprises the first hole and the second hole, the second hole is located below the first hole, and the second hole comprises a trapezoidal cross section; the lower end of the second hole is connected with the stop ring assembly, the stop ring assembly comprises an inner ring and a connecting rod, the inner ring is connected to the lower end of the second hole through the connecting rod, and the diameter of the inner ring is smaller than that of the first hole;

[0014] The valve needle is connected with the connecting plate, the height increasing plate is arranged above the connecting plate, the stop block is connected to the left side of the connecting plate, the upper end of the stop block is connected to the height increasing plate, and in the closed state of the valve needle, the stop block closes the bypass.

[0015] Further, the small-diameter section communicates with the second hole.

[0016] Further, the small-diameter section communicates with the lower end of the first hole.

[0017] Further, the antenna module further comprises a high-speed radio antenna, and the number of the connecting rods is four.

[0024] The beneficial effects of the present application are:

[0025] 1. The first point raised in the background art is that a maintenance hole is arranged on the valve body, and the maintenance hole is blocked by a screw plug. Due to the outdoor bumping characteristics of the vehicle-mounted air conditioner, the frequency of blocking failure is higher than that of the household air conditioner, and the maintenance support in the complex outdoor environment is weaker than that of the household air conditioner, so that the design of the maintenance hole realizes rapid maintenance.

[0026] 2. The second point raised in the background art is that a bypass passage is arranged, so that the air conditioner cannot work normally before maintenance when the valve port is blocked.

[0027] 3. The third point raised in the background art is that a conical second hole is designed in the valve port. When a special maintenance tool or even a wire touches the impurities, the impurities will fall into the second hole. Since the inner diameter of the second hole is small, the impurities will vertically fall and be blocked above the inner circle, and will not fall back into the refrigeration cycle. At the same time, when working normally, if there are small impurities, the valve port cannot be blocked.

[0028] 4. The fourth point raised in the background art is actually assisted by other structures to solve the problem. The valve needle is connected with the connecting plate, the connecting plate is connected with the block, the block blocks the bypass channel, and also plays a guiding and supporting role for the valve needle. The connecting plate is provided with a raised plate. The height of the combined plate of the raised plate and the connecting plate can block the swirl of the valve cavity to some extent, thereby avoiding the generation of excessive swirl, and thus solving three problems through one structure: valve needle guiding and supporting, blocking bypass channel, and blocking excessive swirl.

[0029] 5. The fifth point of the background art is that the maintenance hole and part of the bypass hole are shared. One hole is used to realize two functions. In view of the coordination problem between different holes, the maintenance shared hole is designed as a stepped hole. The large hole section is provided with a maintenance hole, and the small hole section is provided with a bypass hole, thereby simplifying the processing structure.

[0030] Note: The above designs are not in any particular order. Each of them makes the present application have a significant progress compared with the prior art. BRIEF DESCRIPTION OF DRAWINGS
