Description

Technical Field

[0001] This utility model relates to the technical field of electronic oil pump covers for new energy vehicles, and in particular to an electronic oil pump cover for new energy vehicles. Background Technology

[0002] With the booming development of the new energy vehicle industry, the electronic oil pump, as a core component of the power system of new energy vehicles, undertakes the key function of providing stable fluid transmission for the motor, battery thermal management system and hydraulic control system. The pump cover of the electronic oil pump, as an important part of the electronic oil pump, directly affects the reliability, sealing and service life of the oil pump.

[0003] Existing electronic fuel pump covers for new energy vehicles may not be able to effectively intercept oil in layers and cannot quickly install and remove filter components. In actual use, the lack of layer interception design means that large, medium, and fine particles in the oil cannot be filtered step by step and may directly enter the fuel pump. At the same time, the process of disassembling filter components is cumbersome and time-consuming, which is not conducive to daily maintenance and repair. Therefore, we propose an electronic fuel pump cover for new energy vehicles. Utility Model Content

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see the appendix Figure 1 - Appendix Figure 5 A pump cover for an electronic oil pump used in a new energy vehicle includes a base plate 1. Screws 2 are threaded to the four corners of the top of the base plate 1. A pump cover body 3 is fixedly connected to the inner wall of the middle of the base plate 1. A filter assembly 4 is provided inside the pump cover body 3. The filter assembly 4 includes a connecting block 401, a filter frame 403, a guide plate 404, a connecting plate 408, an insert block 410, and a threaded cylinder 411. There are four sets of connecting blocks 401. Bolts 402 are fixedly connected to the top of two sets of connecting blocks 401. Insertion holes 412 are opened on the top of the other two sets of connecting blocks 401. The four sets of connecting blocks 401 are circumferentially distributed and fixedly connected to the inner wall of the pump cover body 3. A coarse filter screen 405, a medium filter screen 406, and a fine filter screen 407 are fixedly connected to the inner wall of the filter frame 403 from bottom to top.

[0023] The base plate 1 serves as the basic structure of the pump cover body 3, supporting the pump cover body 3 and all internal components, and is fixedly connected to the oil pump by the screws 2 at the four corners.

[0024] The guide plate 404 is fixedly installed on the top of the filter frame 403. There are also four sets of connecting plates 408. The top of the two sets of connecting plates 408 is provided with slots 409. There are two sets of inserts 410. The two sets of inserts 410 are fixedly installed on the bottom of the other two sets of connecting plates 408.

[0025] The guide plate 404 is located at the top of the filter frame 403. Its main purpose is to guide the oil to flow evenly into the filter screen area, avoid excessive local flow leading to uneven filtration, and improve filtration efficiency.

[0026] Two sets of insert blocks 410 are slidably connected to the inner walls of two sets of insert holes 412 respectively. The inner walls of two sets of slots 409 are slidably connected to the outer walls of two sets of bolts 402 respectively. Two sets of threaded cylinders 411 are also provided. The inner walls of the two sets of threaded cylinders 411 are threadedly connected to the outer walls of the two sets of bolts 402 respectively. Four sets of connecting plates 408 are circumferentially distributed and fixedly connected to the outer wall of the filter frame 403. The lower surfaces of the four sets of connecting plates 408 are respectively attached to the upper surfaces of the four sets of connecting blocks 401.

[0027] A finger hole is provided at one end of the connecting plate 408 near the pump cover body 3, allowing workers to easily remove the filter frame 403 from inside the pump cover body 3.

[0028] Specifically, through the filter assembly 4, the connecting block 401 and the filter frame 403 form a detachable assembly structure via bolts 402, insertion holes 412, insertion blocks 410, threaded cylinders 411 and connecting plates 408. During installation, the insertion block 410 is inserted into the insertion hole 412, the bolt 402 is fitted into the slot 409, and then the threaded cylinder 411 is tightened to securely fix the filter frame 403. This structure allows workers to quickly complete the installation and disassembly of the filter assembly 4. At the same time, the coarse filter screen 405, medium filter screen 406 and fine filter screen 407 inside the filter frame 403 form a three-stage filtration system, which intercepts large, medium and fine particles and impurities in the oil in layers, improving filtration accuracy and efficiency.

[0029] Please see the appendix Figure 1 Appendix Figure 2 and appendix Figure 6The pump cover body 3 is equipped with an impurity collection component 5, which includes a collection tray 504. An arc-shaped groove 501 is formed on the lower right outer wall of the pump cover body 3. A sliding groove 502 is formed on the surface of the arc-shaped groove 501. A slot 503 is formed on the upper right outer wall of the bottom plate 1. The collection tray 504 is located directly below the fine filter screen 407. A connecting rod 505 is fixedly connected to the surface of the collection tray 504. A slider 506 is fixedly connected to the bottom of the connecting rod 505. The slider 506 is slidably connected to the inner wall of the sliding groove 502. A handle 507 is fixedly connected to the right end of the connecting rod 505. A plug block 508 is fixedly connected to the lower right end of the connecting rod 505. The plug block 508 is inserted into the inside of the slot 503.

[0030] When the plug block 508 is inserted into the slot 503, a rubber sleeve is fixedly connected to its outer wall. During the insertion process, the rubber sleeve is squeezed by the inner wall of the slot 503 and undergoes elastic deformation, fully filling the gap between the slot 503 and the plug block 508. This tight filling not only eliminates the space between the two, but also forms a stable locking structure by means of the friction and elastic rebound of the rubber itself, achieving a firm fixing effect and effectively preventing the plug block 508 from loosening or falling out during use.

[0031] Specifically, after the filtration process is completed, the operator holds the handle 507 and pushes the slider 506 along the slide groove 502, which moves the collection tray 504 along the arc groove 501 into the pump cover body 3. The plug block 508 is inserted into the slot 503 for fixation. At this time, the collection tray 504 is located directly below the filter frame 403, receiving the impurities intercepted by the coarse filter screen 405, the medium filter screen 406 and the fine filter screen 407, preventing impurities from falling into the oil pump and achieving centralized collection of impurities.

[0032] Working principle of this utility model: This utility model is a pump cover for an electronic oil pump in a new energy vehicle. First, the operator installs the base plate 1 onto the electronic oil pump using screws 2. Then, the connecting plate 408 on the outer wall of the filter frame 403 is aligned with the connecting block 401 on the inner wall of the pump cover body 3, so that the insert block 410 is inserted into the insert hole 412, and the slot 409 is fitted with the bolt 402 to complete the initial positioning. Then, the threaded cylinder 411 is tightened so that the lower surface of the connecting plate 408 and the upper surface of the connecting block 401 are tightly fitted, achieving a stable installation of the filter frame 403. During disassembly, the operator loosens the threaded cylinder 411 in the opposite direction, and the filter frame 403 can be easily removed through the finger holes on the connecting plate 408. After the oil enters through the pump cover inlet, it first contacts the guide plate 404, which guides the oil evenly to the filter frame 403. The oil flows sequentially through the coarse filter screen 405, the medium filter screen 406, and the fine filter screen 407. The three filter screens intercept large particles, medium particles, and fine impurities respectively, completing the stratified filtration. After the filtration is completed, the operator holds the handle 507 and pushes the slider 506 along the slide groove 502, which moves the collection tray 504 along the arc groove 501 into the pump cover body 3, so that the collection tray 504 is located directly below the filter frame 403. At this time, the plug-in block 508 is inserted into the slot 503 of the base plate 1. The rubber sleeve on the outer wall of the plug-in block 508 is deformed by compression, filling the gap between the slot 503 and the plug-in block 508, forming a stable engagement, fixing the position of the collection tray 504, and receiving the impurities intercepted during the filtration process, realizing the centralized collection of impurities. When cleaning, the plug-in block 508 is pulled out and the collection tray 504 is removed to clean the impurities.

[0033] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
