Abstract
Description
Technical Field
[0001] This utility model relates to the field of cleaning equipment technology, and in particular to an adjustable electric drive housing high-pressure cleaner. Background Technology
[0002] Electric drive housings are typically made of materials such as aluminum alloy, cast iron, or high-strength steel. They include cavities to house components such as the motor rotor, stator, and bearings, as well as interfaces and brackets for mounting drive controllers, connectors, and other components. In the field of new energy vehicles and motor manufacturing, the surface cleanliness of the electric drive housing, as a core component of the motor, directly affects the motor's performance and lifespan.
[0003] Existing high-pressure washers, when cleaning electric drive housings of different sizes, suffer from problems due to their non-adjustable height. This makes it difficult to match the distance and angle between the high-pressure water flow and the housing surface, resulting in blind spots or over-rinsing. For example, when cleaning large electric drive housings, the water pressure decreases due to the excessive spray distance, making it difficult to effectively remove stubborn stains; when cleaning small housings, the excessively short spray distance can easily cause surface damage. Furthermore, the manual hose retraction method leads to frequent bending and tangling of the hoses, resulting in loose connections and hose wall wear, increasing equipment maintenance frequency and costs. Therefore, an adjustable electric drive housing high-pressure washer is proposed to solve these problems. Utility Model Content

Detailed Implementation
[0030] 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.
[0031] Reference Figure 1 and Figure 2This utility model provides an embodiment of an adjustable electrically driven high-pressure cleaner, including a base 2 and a mounting plate 6. A lifting assembly is installed on the top of the base 2, and a winding assembly is installed on the top of the mounting plate 6. The cleaner body 1 is fixedly connected to the top of the mounting plate 6. The lifting assembly includes a fixing plate 15, which is fixedly connected to the top of the base 2. A drive motor 9 is fixedly connected to the outside of the fixing plate 15. A lead screw 10 is fixedly connected to the output end of the drive motor 9. A mounting block 11 is provided on the outside of the lead screw 10. A set of connecting rods 7 is rotatably connected to the outside of the mounting block 11. The drive motor 9 drives the lead screw 10 to rotate through a coupling. The rotational motion is converted into the linear reciprocating motion of the mounting block 11 through the mounting block 11, realizing the vertical lifting of the mounting plate 6, enhancing the stability of the movement, ensuring that the cleaner can flexibly adapt to workpieces of different heights, and improving cleaning efficiency and stability. The lifting assembly also includes a fixing block 8, which is fixedly connected to the bottom of the mounting plate 6. A slide rail 13 is fixedly connected to the bottom of the mounting plate 6, and a slider 14 is slidably connected to the outside of the slide rail 13. A set of connecting rods 7 is rotatably connected to the outside of the slider 14. A limit plate 12 is fixedly connected to the top of the base 2, and a lead screw 10 is rotatably connected to the middle of the limit plate 12. The slider 14 slides on the slide rail 13, ensuring the smooth lifting and lowering of the mounting plate 6 and preventing swaying or tilting. Under the limiting action of the limit plate 12, the mounting block 11 is prevented from falling off, improving stability. A caster wheel 3 is fixedly connected to the bottom of the base 2. A push rod 4 is fixedly connected to the top of the base 2. The caster wheel 3 and push rod 4 at the bottom of the base 2 enable flexible movement of the equipment to the work area.
[0032] Reference Figure 1 and Figure 3 The winding assembly includes a mounting frame 5, which is fixedly connected to the top of the mounting plate 6. A housing 22 is rotatably connected inside the mounting frame 5, and a coil spring 16 is fixedly connected inside the housing 22. A water pipe 21 is wound around the outside of the housing 22. The winding assembly also includes a fixed shaft 23, which is fixedly connected to the middle of the mounting frame 5. A ratchet 17 is rotatably connected to the outside of the fixed shaft 23. A pressing block 18 is slidably connected to the middle of the mounting frame 5, and a pawl 19 is fixedly connected to the outside of the pressing block 18, engaging with the ratchet 17. A return spring 20 is fixedly connected to the outside of the pawl 19. When the water pipe 21 is manually pulled out, the housing 22 rotates to tighten the coil spring 16, and the ratchet 17 rotates synchronously. After the water pipe 21 is pulled to the appropriate length, the pawl 19, under the action of the return spring 20, locks the ratchet 17 to prevent the housing 22 from reversing and keep the water pipe 21 extended. After use, the pawl 19 is disengaged from the ratchet 17 by pressing the pressing block 18 to compress the spring. At the same time, the coil spring 16 releases potential energy to drive the housing 22 to reverse and rewind the water pipe 21 at a uniform speed, avoiding the water pipe 21 from getting tangled and knotted, reducing wear, and helping to extend the service life of the water pipe 21.
[0033] Working principle: When it is necessary to clean electric drive housings of different heights, the drive motor 9 drives the lead screw 10 to rotate, which drives the mounting block 11 to move along the axial direction of the lead screw 10, thereby driving the two sets of connecting rods 7 to rotate. While the connecting rods 7 move, the slider 14 slides on the slide rail 13, so as to realize the lifting and lowering movement of the mounting plate 6. It can accurately adjust the height of the cleaning machine body 1 and adapt to electric drive housings of different sizes.
[0034] During use, pulling out the water hose 21 rotates the outer casing 22, tightening the coil spring 16, and causing the ratchet 17 to rotate with the outer casing 22. Pulling the water hose 21 to a suitable length causes the pawl 19 to engage the ratchet 17 to prevent rebound, keeping the water hose 21 extended. Turning on the cleaning machine body 1 sprays high-pressure water through the water hose 21 to rinse the electric drive housing. After rinsing, pressing the pressing block 18 disengages the pawl 19 from the ratchet 17. Simultaneously, the coil spring 16 releases its elastic potential energy, driving the outer casing 22 to rotate in the opposite direction, automatically rewinding the water hose 21. This automatic rewinding and unwinding prevents the water hose 21 from tangling, extending its service life.
[0035] 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.
