[0032] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0033] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0034] Example 1:

[0035] Please see Figure 1-3The present invention provides a technical solution: To achieve the above objectives, the present invention provides the following technical solution: A positioning and cleaning device for electronic expansion valves of new energy vehicles, comprising: a frame assembly, including a base 1 and a support bar 2 fixed to each other, and a mounting seat 3 fixed to the top of the support bar 2; a clamping assembly, including a motor 4 installed at the bottom of the mounting seat 3, a drive rod 5 fixed to the output end of the motor 4 and passing through the mounting seat 3, a rotating platform 6 fixed to the top of the drive rod 5, and four sets of clamping members disposed on the top of the rotating platform 6; the clamping members include a movable groove 7 opened on the top of the rotating platform 6, a movable block 8 movably disposed inside the movable groove 7, and a clamping member fixed to the top of the movable block 8. The following components are included: a connecting seat 18; a clamping block 19 mounted on top of the connecting seat 18; a first telescopic rod 9 fixed between the inner wall of one side of the movable slot 7 and the outer wall of one side of the movable block 8; a first spring 10 located outside the first telescopic rod 9; a mounting groove 11 opened on the outer wall of the rotary table 6; a receiving wheel 12 movably mounted inside the mounting groove 11; a channel 13 penetrating the mounting groove 11 and the movable slot 7; an electric telescopic rod 15 mounted on the bottom of the motor 4; a connecting plate 16 fixed to the bottom of the electric telescopic rod 15; a connecting groove 17 opened on the outer wall of the connecting plate 16; and a section fixed to the outer wall of the movable block 8 on the side away from the first telescopic rod 9, passing through the channel 13 and overlapping the receiving wheel 12. The wall includes a pull rope 14; a cleaning assembly comprising a vertical plate 29 fixed to the top of the mounting base 3, a nozzle 30 mounted on the end of the vertical plate 29 near the rotating platform 6, a container 28 mounted on the top of the base 1, cleaning water contained inside the container 28, a water pump mounted inside the container 28, and a pipe 31 mounted at the outlet of the water pump and passing through the top of the container 28 and connecting to the nozzle 30; the first spring 10 has its two ends fixed to the inner wall of one side of the movable groove 7 and the outer wall of one side of the movable block 8, respectively; the pull rope 14 has its end away from the movable block 8 movably mounted inside the connecting groove 17; a barrier frame 32 is mounted on the top of the mounting base 3; and the motor 4 and the electric telescopic rod 15 are both waterproof. It also includes a connecting assembly, which includes an embedding groove 20 on the top of the connecting seat 18, an embedding block 21 fixed to the bottom of the clamping block 19 and embedded in the embedding groove 20, a connecting hole 22 on the outer wall of the connecting seat 18, a second telescopic rod 23 fixed to the inner wall of the connecting hole 22, a second spring 24 located outside the second telescopic rod 23, a connecting strip 25 fixed to one end of the second telescopic rod 23, a limiting hole 27 on the outer wall of the clamping block 19, and a limiting post 26 fixed to one end of the connecting strip 25 near the clamping block 19 and engaged inside the limiting hole 27; the two ends of the second spring 24 are respectively fixed to one end of the connecting strip 25 and the inner wall of the connecting hole 22.

[0036] Specifically, by placing the electronic expansion valve on top of the rotary table 6 and then activating the electric telescopic rod 15, the electric telescopic rod 15 will retract, causing the pull rope 14 to lose tension and become slack. Simultaneously, the first spring 10 will drive the first telescopic rod 9 to retract. The retraction of the first telescopic rod 9 will drive the movable block 8 to move within the movable groove 7. The movable block 8 will then drive the connecting seat 18 and the clamping block 19 to move. At this point, the four clamping components will close together, clamping and fixing the electronic expansion valve in cooperation. Then, the angle of the electronic expansion valve is adjusted according to the angle of contaminants outside the valve. Specifically, the motor 4 is started, and the motor 4 uses the drive rod 5... The rotating table 6 drives the electronic expansion valve to rotate, thereby adjusting the angle of the electronic expansion valve. When the contaminants outside the electronic expansion valve are directly opposite the nozzle 30, the motor 4 is turned off and the water pump is started. Under the action of the water pump, the cleaning water inside the container 28 will enter the nozzle 30 through the pipe 31. The cleaning water will finally be sprayed onto the electronic expansion valve through the nozzle 30, thereby achieving the purpose of cleaning the contaminants outside the electronic expansion valve. Compared with the existing methods, the present invention can automatically perform fixed-point and fixed-position cleaning of the electronic expansion valve, replacing the existing manual cleaning method. It cleans the electronic expansion valve more thoroughly, and the cleaning and clamping force are stable throughout the process, without causing damage to the electronic expansion valve.

[0037] Pulling the connecting bar 25 will stretch the second telescopic rod 23 and the second spring 24, causing the connecting bar 25 to move the limiting post 26. After the limiting post 26 disengages from the limiting hole 27, it will drive the embedded block 21 to disengage from the embedding groove 20. Subsequently, it will drive the clamping block 19 to separate from the connecting seat 18, thus disassembling the clamping block 19. Then, a new clamping block 19 can be placed on top of the connecting seat 18. After the embedded block 21 is embedded in the embedding groove 20, the connecting bar 25 is released. Under the action of the second spring 24, the second telescopic rod 23 will retract, and the second telescopic rod 23 will then drive the connecting bar 25 to move. When the limiting post 26 engages in the limiting hole 27, the new clamping block 19 can be fixed. Therefore, this invention can replace different clamping blocks 19, making it suitable for clamping and fixing different types of electronic expansion valves, thus having high applicability.

[0038] Example 2:

[0039] Please see Figure 1 , 4-6, This invention provides a technical solution: a fixed-point cleaning device for electronic expansion valves of new energy vehicles, further comprising a recycling component. The recycling component includes a T-shaped groove 33 symmetrically opened on the top of the base 1, a T-shaped slider movably installed inside the T-shaped groove 33, a collection frame 34 fixed on the top of the T-shaped slider, a filter plate 37 placed inside the collection frame 34, an outlet pipe 35 installed on the outer wall of the collection frame 34, and a valve body 36 installed on the outer wall of the outlet pipe 35. A limit ring 38 is fixed on the inner wall of the collection frame 34, and the limit ring 38 abuts against the bottom of the filter plate 37. The filter plate 37 consists of a pretreatment layer, an adsorption layer, and a filter layer from top to bottom. The pretreatment layer is made of high-strength polyester fiber mesh, the adsorption layer is made of activated carbon, and the filter layer is made of... Made of polypropylene meltblown filter element, and also includes a self-locking assembly. The self-locking assembly includes a strip 39 fixed to the outer wall of container 28, a locking groove 40 opened at one end of the strip 39, a locking bar 41 fixed to the outer wall of collection frame 34 and located inside the locking groove 40, a return groove 42 opened on the inner wall of the locking groove 40, a perforation 43 opened on the outer wall of the strip 39 and communicating with the return groove 42, a fixing groove 47 opened on the outer wall of the locking bar 41, a locking rod 44 movably set inside the perforation 43, a pull plate 45 fixed to one end of the locking rod 44, a fixing bar 48 fixed to the other end of the locking rod 44 and located inside the fixing groove 47, and a third spring 46 located outside the locking rod 44. The two ends of the third spring 46 are respectively fixed to one end of the pull plate 45 and the outer wall of the strip 39.

[0040] The recycling component is used to recycle the cleaning water after cleaning the electronic expansion valve. Specifically, the cleaning water after cleaning the electronic expansion valve will drip into the collection frame 34. During this process, the filter plate 37 will filter the cleaning water. The filtered cleaning water can be reused, which is more energy-saving and environmentally friendly. With the cooperation of the T-shaped slide 33 and the T-shaped slider, the collection frame 34 can be pulled out from under the mounting base 3. Then, the valve body 36 is opened, and the filtered cleaning water will be discharged from the inside of the collection frame 34 through the outlet pipe 35, which facilitates the reuse of the cleaning water.

[0041] The self-locking assembly is used to fix the collection frame 34 to prevent it from moving, thereby ensuring the efficiency of cleaning water recycling. Specifically, under the action of the third spring 46, the locking rod 44 will always be driven to be located in the through hole 43, and the fixing strip 48 fixed at one end of the locking rod 44 is located inside the fixing groove 47, which indirectly fixes the locking strip 41 inside the locking groove 40 of the long strip 39, thereby achieving the purpose of fixing the collection frame 34 and preventing it from moving, thus ensuring the efficiency of cleaning water recycling.

[0042] It should be noted that when the collection frame 34 needs to be pulled out, the locking rod 44 should be pulled by the pull plate 45 beforehand. At this time, the third spring 46 will be stretched, and the locking rod 44 will move within the through hole 43. The locking rod 44 will also drive the fixing strip 48 to move synchronously, and the fixing strip 48 will disengage from the fixing groove 47 and be located inside the return groove 42. At this time, the fixing of the locking strip 41 and the long strip 39 (locking groove 40) can be released, and then the collection frame 34 can be pulled out. On the one hand, by pulling out the collection frame 34, it is convenient to disassemble and maintain the filter plate 37, thereby improving the working efficiency of the filter plate 37. On the other hand, since the filter plate 37 is placed directly inside the collection frame 34 and is aligned with the top of the limiting ring 38, the collection frame 34 can be pulled out. Since the filter plate 37 is directly removed from the collection frame 34, the disassembly of the filter plate 37 is relatively simple and convenient. After the cleaning water in the collection frame 34 is reused, the collection frame 34 is pushed back. At the same time, the locking bar 41 will also be located in the locking groove 40 of the long bar 39. During this process, the locking bar 41 will squeeze the fixing bar 48, and the fixing bar 48 will be squeezed to the retraction groove 42. The third spring 46 will also stretch. When the fixing groove 47 and the fixing bar 48 are aligned, the third spring 46 will drive the locking rod 44 to push the fixing bar 48 into the fixing groove 47, thus fixing the locking bar 41 and fixing the collection frame 34.

[0043] Working principle:

[0044] Install the base 1, support bar 2, and mounting base 3 into the designated positions. Place the electronic expansion valve on top of the rotary table 6, and then activate the electric telescopic rod 15. At this time, the electric telescopic rod 15 will retract, and the pull rope 14 will lose tension and become slack. Simultaneously, the first spring 10 will drive the first telescopic rod 9 to retract. The retraction of the first telescopic rod 9 will drive the movable block 8 to move within the movable groove 7. The movable block 8 will then drive the connecting seat 18 and the clamping block 19 to move. At this time, the four sets of clamping parts will close together, and with the cooperation of the four sets of clamping parts, the electronic expansion valve will be clamped and fixed. Then, adjust the angle of the electronic expansion valve according to the angle of the contaminants outside the electronic expansion valve. Start the motor 4. The motor 4 uses the drive rod 5 to drive the rotary table 6. The electronic expansion valve rotates to adjust its angle. When contaminants outside the electronic expansion valve are directly opposite the nozzle 30, the motor 4 is turned off and the water pump is started. Under the action of the water pump, the cleaning water inside the container 28 enters the nozzle 30 through the pipe 31. The cleaning water is then sprayed onto the electronic expansion valve through the nozzle 30, thus cleaning the contaminants outside the electronic expansion valve. Under the action of the blocking frame 32, the cleaning water after cleaning the electronic expansion valve drips into the collection frame 34. During this process, the filter plate 37 filters the cleaning water, and the filtered cleaning water can be reused, which is energy-saving and environmentally friendly. Furthermore, with the cooperation of the T-shaped chute 33 and the T-shaped slider, the collection frame 34 can be... 4. Pull out from under the mounting base 3, then open the valve body 36. The filtered cleaning water will be discharged from the inside of the collection frame 34 through the outlet pipe 35, thus facilitating the reuse of the cleaning water. Under the action of the third spring 46, the locking rod 44 will always be driven to be located in the through hole 43, and the fixing strip 48 fixed at one end of the locking rod 44 is located inside the fixing groove 47, indirectly fixing the locking strip 41 inside the locking groove 40 of the long strip 39, thereby achieving the purpose of fixing the collection frame 34 and preventing the collection frame 34 from moving, thus ensuring the efficiency of cleaning water recovery. When it is necessary to pull out the collection frame 34, first use the pull plate 45 to pull the locking rod 44 in advance. At this time, the third spring 46 will be stretched, and the locking rod 44 will move in the through hole 43, and the locking rod 44 will drive the fixing strip 44 to move in the through hole 43. The fixing bar 48 moves synchronously, and the fixing bar 48 will disengage from the fixing groove 47 and be located inside the retraction groove 42. At this time, the fixing of the locking bar 41 and the long bar 39 (locking groove 40) can be released. Then, the collection frame 34 can be pulled out. On the one hand, by pulling out the collection frame 34, it is convenient to disassemble and maintain the filter plate 37, thereby improving the working efficiency of the filter plate 37. On the other hand, since the filter plate 37 is placed directly inside the collection frame 34 and abuts against the top of the limiting ring 38, the filter plate 37 can be directly removed from the collection frame 34. The disassembly of the filter plate 37 is relatively simple and convenient. After the cleaning water in the collection frame 34 is reused, the collection frame 34 is pushed back. At the same time, the locking bar 41 will also be located inside the locking groove 40 of the long bar 39.During this process, the locking bar 41 will press the fixing bar 48, and the fixing bar 48 will be pressed into the retraction groove 42. The third spring 46 will also stretch. When the fixing groove 47 corresponds to the fixing bar 48, the third spring 46 will drive the locking rod 44 to push the fixing bar 48 into the fixing groove 47, thus fixing the locking bar 41 and fixing the collection frame 34. After the electronic expansion valve is cleaned, the electric telescopic rod 15 is activated. The electric telescopic rod 15 will stretch. The electric telescopic rod 15, together with the connecting plate 16 and the connecting groove 17, pulls the pull rope 14. At this time, the pull rope 14 will move on the receiving wheel 12 of the mounting groove 11, and the entire pull rope 14 will be in a taut state. The pull rope 14 will then pull the movable block 8 through the channel 13. The movable block 8 will move in the movable groove 7, while the first telescopic rod 9 and the first spring 10 are in a stretching motion. At this time, the four clamping parts will separate and release the fixation of the electronic expansion valve. Then the electronic expansion valve can be cleaned. At this point, the cleaning of the electronic expansion valve is complete, and the connecting strip 25 can be pulled. At this time, the second telescopic rod 23 and the second spring 24 within the connecting hole 22 will stretch, causing the connecting strip 25 to move the limiting post 26. Once the limiting post 26 disengages from the limiting hole 27, it drives the insert block 21 to disengage from the insert groove 20. Subsequently, the clamping block 19 can be separated from the connecting seat 18, achieving the purpose of disassembling the clamping block 19. A new clamping block 19 can then be placed on top of the connecting seat 18. After the insert block 21 is inserted into the insert groove 20, the connecting strip 25 is released. Under the action of the second spring 24, the second telescopic rod 23 will retract, and the second telescopic rod 23 will then drive the connecting strip 25 to move. When the limiting post 26 engages within the limiting hole 27, the new clamping block 19 can be fixed. Therefore, this invention allows for the replacement of different clamping blocks 19, enabling it to clamp and fix different types of electronic expansion valves, thus exhibiting high applicability.
