Description

Technical Field

[0001] The present invention relates to the technical field of new energy vehicles, and in particular to an air-conditioning system for a new energy vehicle. Background Art

[0002] New energy vehicle air conditioning systems are air conditioning systems designed specifically for electric vehicles (EVs) and other new energy vehicles. Compared with traditional fuel vehicle air conditioning systems, these air conditioning systems have some unique technical and design requirements because they need to take into account the use and charging of the battery, as well as improving the overall energy efficiency of the vehicle. The design of new energy vehicle air conditioning systems must not only ensure the owner's comfort experience, but also take into account the energy efficiency and endurance of the battery. Similar to traditional automotive air conditioning, electric vehicle air conditioning systems usually also contain core components such as compressors, evaporators, condensers, and expansion valves. The difference is that the compressor of an electric vehicle is usually driven by an electric motor instead of an internal combustion engine. This means that the compressor drive is fully electric, and the energy efficiency of the air conditioning system is closely related to the battery charge and temperature changes.

[0003] Therefore, the air-conditioning system of new energy vehicles cannot be without devices such as condensers. However, the existing condensers used in new energy vehicles will accumulate impurities and dust in the air on the heat dissipation fins during long-term use, resulting in accumulation of dirt in the condenser and reducing the heat exchange efficiency. Therefore, after a certain period of use, the car needs to be disassembled to perform maintenance and cleaning on the condenser. The existing maintenance method generally requires staff to perform corresponding cleaning within a certain period of time, otherwise it will affect the air conditioning cooling effect.

[0027] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0028] See also Figure 1-7 As shown, a new energy vehicle air conditioning system includes a condenser 1, and also includes: a fan 2 installed on one side of the condenser 1, the two sides of the rear side of the condenser 1 are respectively connected with a first pipe 3 and a second pipe 4, one side of the second pipe 4 is connected with a liquid storage dryer 5, one side of the first pipe 3 is connected with a compressor body 6, one side of the compressor body 6 is connected with a third pipe 7, one side of the third pipe 7 is connected with an expansion valve 8, one side of the expansion valve 8 is connected with an evaporator body 9, and one side of the liquid storage dryer 5 is connected with a fourth pipe 10. It should be noted that: the condenser 1, the fan 2, the first pipe 3, the second pipe 4, the liquid storage dryer 5, the compressor body 6, the third pipe 7, the expansion valve 8, the evaporator body 9 and the fourth pipe 10 are all devices with relatively mature applications in the prior art. The specific model can be selected according to actual needs and will not be repeated here. One side of the fourth pipe 10 runs through the interior of the expansion valve 8 and is connected to the evaporator body 9;

[0029] The support plates 11 are fixed to the top and bottom of both sides of the condenser 1. The fixing of the support plates 11 and the condenser 1 facilitates the fixing of the limit rod 12. The front side of the support plate 11 is fixedly connected to the limit rod 12. A positioning shell 13 is provided at the bottom of the limit rod 12. The mounting member 15 provided inside the positioning shell 13 facilitates the installation and fixing of the filter plate 14. The front side of the condenser 1 is provided with a filter plate 14. The interior of the positioning shell 13 is fixedly connected with a mounting member 15 for mounting the filter plate 14. The mounting member 15 includes a second spring 1501. Extension plates 16 are fixedly connected to both sides of the condenser 1. A fixing frame 17 is fixedly connected to one side of the condenser 1. The fixing frame 17 cooperates with the extension plate 16 to facilitate the driving work of the auxiliary driving member 18. A driving member 18 for cleaning the filter plate 14 is fixedly connected to one side of the fixing frame 17. The driving member 18 includes a dual-axis motor 1801 and an internal threaded connecting frame 1802.

[0030] The surface of the limiting rod 12 is sleeved with a sliding plate 19, and the positioning shell 13 can be slidably connected by fixing the sliding plate 19 with the positioning shell 13, and the final stroke of the sliding plate 19 can be limited by the positioning ring 20. The bottom of the sliding plate 19 is fixedly connected to the positioning shell 13, and one side of the limiting rod 12 is fixedly connected with the positioning ring 20, and one side of the positioning ring 20 is fixedly connected with a first spring 21, which is fixed between the support plate 11 and the positioning shell 13 through the first spring 21. When the user needs to remove the filter plate 14, the positioning shell 13 can be pushed to one side and the first spring 21 can be squeezed to facilitate the disassembly and assembly of the mounting member 15, so as to prevent the disassembly distance from being affected by the internal threaded connecting plate 1805, resulting in disassembly. The spacing is not enough, and the filter plate 14 cannot be disassembled. One side of the first spring 21 is fixedly connected to the support plate 11. The top and bottom of both sides of the filter plate 14 are fixedly connected with plug plates 22. The plug plates 22 cooperate with the mounting parts 15 to facilitate the installation and fixation of the filter plate 14. The top and bottom of the plug plates 22 are fixedly connected with reinforcement blocks 23. One side of the reinforcement block 23 is fixedly connected to the filter plate 14. Through the setting of the reinforcement block 23, the connection strength between the plug plate 22 and the filter plate 14 can be improved. One side of the extension plate 16 is fixedly connected with a reinforcement plate 24. Through the fixed connection of the reinforcement plate 24 to the condenser 1, the connection strength between the extension plate 16 and the condenser 1 can be improved. One side of the reinforcement plate 24 is fixedly connected to the condenser 1.

[0031] The dual-axis motor 1801 is fixed to one side of the fixing frame 17, and the output end face of the dual-axis motor 1801 is fixedly connected with a screw 1803, and the end of the screw 1803 away from the dual-axis motor 1801 is rotatably connected to the extension plate 16 through a bearing, and the internal threaded connecting frame 1802 is respectively threadedly connected to the surfaces of the two screws 1803, and the side of the internal threaded connecting frame 1802 close to the filter plate 14 is fixedly connected with the first soft brush assembly 1804. When the dual-axis motor 1801 is turned on to drive the screw 1803 to rotate, the two internal threaded connecting frames 1802 will drive the first soft brush assembly 1804 to cooperate with the connecting plate 1805 and the second soft brush assembly 1806 move in opposite directions, and during the movement of the internal threaded connecting frame 1802, it will move in a limited position on the surface of the slide bar 1807, so that the impurities accumulated on the surface of the filter plate 14 can be automatically cleaned off, thereby reducing the frequency of manual cleaning. One side of the internal threaded connecting frame 1802 is fixedly connected to the connecting plate 1805, one side of the connecting plate 1805 is fixedly connected to the second soft brush assembly 1806, and the internal sliding connection of one side of the internal threaded connecting frame 1802 is connected to the slide bar 1807, and both ends of the slide bar 1807 are fixedly connected to the extension plate 16.

[0032] The second spring 1501 is fixed to one side of the interior of the positioning shell 13, the bottom of the second spring 1501 is fixedly connected to the second clamping plate 1502, one side of the second clamping plate 1502 is fixedly connected to the first inclined plate 1503, one side of the first inclined plate 1503 is slidably connected to the second inclined plate 1504, one side of the second inclined plate 1504 is fixedly connected to a push rod 1505, one side of the push rod 1505 penetrates to the outside of the positioning shell 13 and is fixedly connected to a pressing ring 1506, one side of the second inclined plate 1504 is fixedly connected to the inner wall of the positioning shell 13 with a third spring 1507 for assisting the second inclined plate 1504 in resetting. However, when the user needs to disassemble the filter plate 14, the positioning shell 13 is first squeezed inward to drive the sliding plate 19 to move on the surface of the limiting rod 12, and at the same time The first spring 21 is squeezed to leave sufficient space between the filter plate 14 and the internal threaded connecting frame 1802, and then the pressing ring 1506 is pressed to make the push rod 1505 drive the second inclined plate 1504 to move to one side. As the second inclined plate 1504 moves, the third spring 1507 is stretched, and then the second inclined plate 1504 presses against the first inclined plate 1503 to move. At this time, the first inclined plate 1503 will be forced to drive the second clamping plate 1502 to move upward on the surface limit of the retaining rod 1508 and squeeze the second spring 1501. Then the second clamping plate 1502 is separated from the surface of the plug plate 22, and the filter plate 14 can be disassembled. The retaining rods 1508 are slidably connected to both sides of the second clamping plate 1502, and the two ends of the retaining rods 1508 are fixedly connected to the inner wall of the positioning shell 13.

[0033] Working principle: first, when the user uses the condenser 1 for air conditioning, the dust and impurities contained in the air will be filtered through the filter plate 14 on the surface of the filter plate 14. When the dust and impurities accumulate to a certain extent, the dual-axis motor 1801 can be turned on to drive the screw 1803 to rotate. At this time, the two internal threaded connecting frames 1802 will drive the first soft brush assembly 1804 to cooperate with the connecting plate 1805 and the second soft brush assembly 1806 to move relative to each other, and during the movement of the internal threaded connecting frame 1802, it will move on the surface of the slide bar 1807 to limit the movement, so that the impurities accumulated on the surface of the filter plate 14 can be automatically cleaned up, thereby reducing the frequency of manual cleaning, and the dual-axis motor 1801 can be designed as a periodic cleaning system. According to the pollution degree of the use environment, a timed cleaning function can be set. For example, the cleaning function can be automatically started every time the air conditioner runs for a certain number of hours. The cleaning function can be automatically started at regular intervals. If the condenser 1 and the filter plate 14 need to be disassembled for maintenance, the filter plate 14 can drive the sliding plate 19 to move on the surface of the limit rod 12 by squeezing the positioning shell 13 inward, and at the same time squeeze the first spring 21 to leave sufficient space between the filter plate 14 and the internal threaded connecting frame 1802. Then, the pressing ring 1506 is pressed to make the push rod 1505 drive the second inclined plate 1504 to move to one side. As the second inclined plate 1504 moves, the third spring 1507 is stretched, and then the second inclined plate 1504 presses the first inclined plate 1503 to move. At that time, the first inclined plate 1503 will be forced to drive the second clamping plate 1502 to move upward on the surface of the retaining rod 1508 and squeeze the second spring 1501. Then, the second clamping plate 1502 is separated from the surface of the plug plate 22, and the filter plate 14 can be disassembled.
