Description

Technical Field

[0001] The utility model relates to a steering assist pump system, and more specifically to an oil storage pot for a booster pump. Background Art

[0002] An automotive steering assist pump is also called a power steering pump. The power steering pump is the power source of a hydraulic power steering system. It uses the engine as a transmission medium to convert mechanical energy into hydraulic energy. The steering gear converts the hydraulic energy into mechanical energy through the hydraulic oil output by the oil pump, so as to reduce the operation intensity of the driver and improve the maneuverability of the whole vehicle.

[0003] However, with long-term use, a large amount of metal chips will be mixed in the power steering fluid, which will further reduce the quality of the power steering fluid and further deteriorate the assist effect. Therefore, after the oil storage pot has been used for a long time, it is necessary to replace the power steering fluid in the oil storage pot. During the replacement process, an external extraction device is required to extract the old oil in the oil storage pot, and then the oil in the pipeline is replaced by injecting new oil and turning the steering wheel. However, in the above process, since the oil storage pot is not removed, the replacement of the oil in the pipeline requires repeated operations. On the one hand, this makes the replacement of the power steering fluid more difficult, and on the other hand, it will cause more new oil to be used during the replacement process, resulting in more waste. Summary of the Utility Model

[0004] Aiming at the deficiencies of the prior art, the purpose of the utility model is to provide an oil storage pot for a booster pump that is convenient for replacing power steering fluid.

[0005] To achieve the above purpose, the utility model provides the following technical solution: An oil storage pot for a booster pump, comprising a pot body, an upper cover and a filter plate. The pot body is provided with an oil inlet and an oil outlet. The upper cover is detachably installed at the upper end of the pot body. The filter plate is in a straight plate structure and is inserted into the pot body to evenly divide the pot body into left and right cavities. The oil inlet is arranged in the right cavity, and the oil outlet is arranged in the left cavity. A number of filter holes are evenly distributed on the filter plate. The filter holes communicate the left cavity and the right cavity. A filter screen is arranged in the filter holes. A liftable cover plate is arranged on the side of the filter plate facing the right cavity. Through holes corresponding to the filter holes in number and position are opened on the cover plate, so that the through holes coincide with the filter holes through the up and down lifting of the cover plate to communicate the left cavity and the right cavity, or are staggered from each other to disconnect the left cavity and the right cavity.

[0006] As a further improvement of the present utility model, a receiving groove is formed on the lower end surface of the middle part of the upper cover. A lifting rod is fixed in the middle of the upper side edge of the cover plate. A lifting handwheel is rotatably arranged at the upper end of the upper cover. The upper end of the lifting rod passes through the upper cover and then penetrates into the lifting handwheel and is threadedly connected to the lifting handwheel. Slide rails are fixed on both side edges of the filter plate, and both side edges of the cover plate are slidably arranged on the slide rails.

[0007] As a further improvement of the present utility model, a plurality of magnetic rods are fixed on the side of the cover plate facing away from the filter plate, and the magnetic rods are located at the position between the upper and lower through holes on the cover plate.

[0008] As a further improvement of the present utility model, both the oil inlet and the oil outlet are located at the lower end of the kettle body.

[0009] The beneficial effects of the present utility model are as follows: By setting the kettle body, the upper cover, the filter plate, the oil inlet and the oil outlet, a structure of an oil storage kettle can be effectively formed. And by setting the filter plate and the cover plate, the kettle body can be effectively divided into a left cavity and a right cavity. During the process of changing oil, after the old oil in the oil storage kettle is pumped out completely, the old oil is received through the right cavity, and new oil is filled into the left cavity. In this way, the replacement of the power steering oil in the pipeline can be completed quickly and effectively, and at the same time, the use of power steering oil can be saved.

[0011] Figure 2 is Figure 1 a schematic structural view of the filter plate and the cover plate in Detailed Description of the Invention

[0012] The following will further describe the present utility model in detail with reference to the embodiments given in the drawings.

[0013] Refer to Figures 1 to 2As shown in the figure, an oil storage pot for a booster pump in this embodiment includes a pot body 1, an upper cover 2 and a filter plate 3. An oil inlet 4 and an oil outlet 5 are provided on the pot body 1. The upper cover 2 is detachably installed at the upper end of the pot body 1. Its characteristics are as follows: The filter plate 3 is in a straight plate structure and is inserted into the pot body 1 to evenly divide the inside of the pot body 1 into two left and right cavities. The oil inlet 4 is arranged in the right cavity, and the oil outlet 5 is arranged in the left cavity. A number of filter holes 31 are evenly distributed on the filter plate 3. The filter holes 31 communicate with the left cavity and the right cavity. A filter screen 32 is arranged in the filter holes 31. A liftable cover plate 6 is arranged on the side of the filter plate 3 facing the right cavity. Through holes 61 corresponding to the filter holes 31 in number and position are opened on the cover plate 6. By lifting the cover plate 6 up and down, the through holes 61 coincide with the filter holes 31 to communicate the left cavity and the right cavity, or are staggered from each other to disconnect the left cavity and the right cavity. During the process of replacing the booster oil with the oil storage pot of this embodiment, first, the existing old oil in the oil storage pot is pumped out by an external extraction device. Then, the filter plate 3 is closed by using the cover plate 6, so that the left cavity and the right cavity are independent of each other. Then, the external extraction device is used to continuously extract the old oil in the right cavity, and new oil is injected into the left cavity to realize the rapid replacement of the old oil in the pipeline. Compared with the unified space method in the prior art, it can avoid the problem that more new oil is required due to the mixing of the old oil output and the new oil in the pipeline after injecting new oil, and more steering operations are required during the replacement process.

[0014] As a specific improvement embodiment, a receiving groove 21 is opened on the lower end surface of the middle part of the upper cover 2. The middle part of the upper side edge of the cover plate 6 is fixed with a lifting rod 62. The upper end of the upper cover 2 is rotatably provided with a lifting handwheel 22. The upper end of the lifting rod 62 passes through the upper cover 2 and then penetrates into the lifting handwheel 22 and is threadedly connected with the lifting handwheel 22. Slide rails 33 are fixed on both side edges of the filter plate 3. Both side edges of the cover plate 6 are slidably arranged on the slide rails 33. Through the above structural arrangement, the self-locking lifting structure can be effectively realized by using the threaded cooperation between the lifting handwheel 2 with the cover plate 6, so as to better use the way that the filter holes 31 and the through holes 61 coincide or are misaligned to realize the connection and disconnection between the left cavity and the right cavity.

[0015] As a specific improvement embodiment, a number of magnetic rods 63 are fixed on the side of the cover plate 6 facing away from the filter plate 3. The magnetic rods 63 are located between the upper and lower through holes 61 on the cover plate 6. Through the arrangement of the magnetic rods 63, the metal chips in the booster oil can be effectively adsorbed, and the service life of the booster oil can be increased.

[0016] As a specific implementation of the improvement, both the oil inlet 4 and the oil outlet 5 are located at the lower end of the kettle body 1. In this way, the external extraction device can directly connect to the oil inlet 4 to extract the oil fluid, and the gravity also assists in the extraction process, enabling a more thorough extraction.

[0017] In summary, for the oil storage kettle of the booster pump in this embodiment, through the combined structure of the filter plate 3 and the cover plate 6, a left cavity and a right cavity that are isolated from each other can be formed inside the kettle body 1, thereby avoiding the problems of the mixing of new oil and old oil during the oil change process, which leads to a longer oil change process and a larger amount of new oil required.

[0018] The above are only the preferred implementation modes of the present invention. The protection scope of the present invention is not limited to the above embodiments. All technical solutions within the idea of the present invention belong to the protection scope of the present invention. It should be pointed out that for those of ordinary skill in the art in this technical field, several improvements and refinements made without departing from the principle of the present invention should also be regarded as within the protection scope of the present invention.
