[0002] The existing method for replacing the gearbox oil and air compressor oil of an electric passenger car still uses a relatively traditional method, which has two disadvantages: one is that more than two people are required to operate, and there is a phenomenon of grease dripping during the operation, which further causes the ground to be slippery and there is a risk of personnel injury; the other is that it is difficult to grasp the oil level inside the gearbox and air compressor of the electric passenger car, resulting in equipment damage during the oil change process and low work efficiency.

[0003] In view of the disadvantages such as a large number of gearboxes of electric passenger cars, urgent grease replacement time, high-altitude operation during operation requiring a special person to hold the ladder and easy grease dripping when replacing the gearbox oil and air compressor oil of electric passenger cars, and the influence of manual oil injection when replacing the gearbox oil and air compressor oil of electric passenger cars, there are disadvantages such as easy fatigue of operators resulting in safety risks, grease dripping causing waste of resources, and low work efficiency. Therefore, a dual-purpose tool for refueling the gearbox oil and air compressor oil of an electric passenger car is specially designed. Content of the Utility Model

Detailed implementation mode

[0029] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0030] Embodiment:

[0031] Please refer to Figures 1 - 5 As shown, the present utility model is a multi-functional tool for filling gearbox oil and air compressor oil of an electric passenger car, including

[0032] Base plate 1;

[0033] Moving assembly, which is arranged below the base plate 1 and is used to drive the base plate 1 to move;

[0034] Lifting assembly, which is arranged above the base plate 1, and a support frame is installed on one side of its upper end;

[0035] Oil barrel 3, the oil barrel 3 is placed on the support frame, and the oil barrel 3 is lifted by the lifting assembly;

[0036] Oil injection assembly, which is arranged below the support frame and is connected to the oil barrel 3.

[0037] The upper wall of the base plate 1 is fixedly connected with a handrail 2.

[0038] The moving components include front universal wheels 4 and rear universal wheels 16. Both of the two front universal wheels 4 are fixedly arranged on the lower wall of the substrate 1, and both of the two rear universal wheels 16 are fixedly arranged on the lower wall of the substrate 1. A brake pad is provided on the rear universal wheel 16.

[0039] The lifting component includes a telescopic oil cylinder rod 5, and the lower end of the telescopic oil cylinder rod 5 is fixedly connected to the upper wall of the substrate 1.

[0040] A foot-operated control pump 6 is provided on one side of the substrate 1. There is a docking pipe 7 between the foot-operated control pump 6 and the telescopic oil cylinder rod 5. A connection port is opened on the outer wall of the lower end of the telescopic oil cylinder rod 5. One end of the docking pipe 7 is inserted and connected to the connection port through a quick-insert female head, and the other end of the docking pipe 7 is inserted and connected to the output port of the foot-operated control pump 6 through a quick-insert male head.

[0041] A control switch 8 is provided on the foot-operated control pump 6.

[0042] The support frame is composed of rib plates 9 and a platform plate 10. Both of the two rib plates 9 are fixedly arranged on one side of the upper end of the lifting component, and the platform plate 10 is fixedly arranged on the upper wall of the rib plates 9.

[0043] A patterned surface is provided on the upper wall of the platform plate 10. A protective fence 11 is fixedly connected to the platform plate 10. The protective fence 11 is rectangular in shape and is designed with an opening on one side;

[0044] By providing a patterned surface on the upper wall of the platform plate 10, during the specific working process, when a person places the oil barrel 3 on the platform plate 10, the bottom wall of the oil barrel 3 contacts the platform plate 10 through the patterned surface, which is convenient for increasing the friction force and further playing an anti-slip role;

[0045] Among them, by providing the protective fence 11, it can effectively prevent the oil barrel 3 from moving, tilting or tipping over due to external forces during the lifting process.

[0046] The oil injection component includes an oil pipe 12, an oil gun 13, a flow display meter 14 and a cut-off valve 15. The upper end of the oil pipe 12 is inserted and connected to a port provided on the bottom wall of the oil barrel 3 through a quick plug. Both ends of the flow display meter 14 are communicated with one end of the oil gun 13 and the lower end of the oil pipe 12 respectively. The cut-off valve 15 is provided on the oil gun 13.

[0047] As can be seen from the above, during operation, first inject the new lubricating oil to be filled into the oil barrel 3 in advance, move the tooling to a reasonable location, lock the rear universal wheel 16 with the brake pad, and turn the control switch 8 on the foot-operated control pump 6 to the "ON" position. Further, the staff drives the telescopic oil cylinder rod 5 to rise through the foot-operated control pump 6. After rising to a certain height (higher than the gearbox or air compressor of the electric multiple unit), stop rising. At this time, the operator puts the oil gun 13 into the fuel tank of the electric multiple unit that needs to be filled with lubricating oil, and opens the cut-off valve 15 to start filling with new oil. At this time, the lubricating oil automatically injects into the gearbox or air compressor through the oil pipe 12 due to gravity, thus completing the new oil filling operation. The operator can also intuitively understand the amount of lubricating oil filled through the flow display meter 14;

[0048] After the operation is completed, first close the cut-off valve 15 of the oil gun 13, then lower the oil barrel 3 through the foot-operated control pump 6, and then open the brake pad set on the rear universal wheel 16 to start the operation of the next work station. If different types of lubricating oil need to be filled, replacing a set of new fuel tanks and oil filling parts can achieve the filling of different types of lubricating oil. This tooling can effectively improve work efficiency, reduce human resource costs, and reduce safety risks during the operation. When filling lubricating oil, the operator only needs to manually control the oil tank lifting device to complete the filling of new lubricating oil. If the new lubricating oil in the oil barrel 3 is not enough, lower the oil barrel 3 and then quickly add new lubricating oil, and then raise the oil barrel 3. Further opening the cut-off valve 15 can effectively and conveniently fill with new lubricating oil;

[0049] Among them, a one-way electric pump can be installed on the basis of the present utility model to increase the oil filling speed.
