Detailed Description
The following detailed description of the embodiments of the present invention will be given with reference to the accompanying drawings, for the purpose of helping those skilled in the art to understand more completely, accurately and deeply the conception and technical solution of the present invention, and to facilitate its implementation.
It should be noted that, in the following embodiments, the "first" and "second" do not represent an absolute distinction relationship in structure and/or function, nor represent a sequential execution order, but merely for convenience of description.
As shown in fig. 1, the utility model provides an unmanned aerial vehicle fluid pressure type brake system fluid filling device, including storage bucket 7, change-over valve 3 and the syringe 1 of being connected with change-over valve 3, change-over valve 3 includes one-way oil inlet 11 of being connected with storage bucket 7 through first defeated oil pipe 9 and the one-way oil-out 4 of being connected with the defeated oil pipe 12 of second, and syringe 1 is constructed for being used for the extraction to come from the fluid of one-way oil inlet 11 and with fluid through the defeated oil pipe 12 of one-way oil-out 4 injection second.
Specifically, as shown in fig. 1, one end of a first oil delivery pipe 9 is connected to an oil outlet 8 provided at the bottom of the oil storage bucket 7, and the other end of the first oil delivery pipe 9 is connected to a one-way oil inlet 11. The oil storage barrel 7 is used for storing oil, the dust cover 6 is arranged at the top of the oil storage barrel 7, the air inlet 10 is formed in the dust cover 6, the oil outlet 8 of the oil storage barrel 7 is formed in the bottom, and the first oil delivery pipe 9 guides the oil in the oil storage barrel 7 to the one-way oil inlet 11 of the change-over valve 3. One end of the second oil delivery pipe 12 is connected with the one-way oil outlet 4 of the change-over valve 3, the other end of the second oil delivery pipe 12 is provided with an adaptive joint 5, the adaptive joint 5 is used for being spliced with an oil filling port of the hydraulic brake system of the unmanned aerial vehicle, and the second oil delivery pipe 12 guides oil from the one-way oil outlet 4 of the change-over valve 3 to the hydraulic brake system of the unmanned aerial vehicle.
As shown in fig. 1, the switching valve 3 has a first interface end, a second interface end and a third interface end. The first connection end of the changeover valve 3 is provided with a non-return valve, forming a non-return oil inlet 11, which allows oil to flow only from the first oil line 9 into the changeover valve 3 and then into the injector 1. The second interface end of change-over valve 3 also sets up a check valve, forms one-way oil-out 4, and this check valve makes the fluid that comes from syringe 1 can only flow to second defeated oil pipe 12 from change-over valve 3, and the refilling that flows into unmanned aerial vehicle fluid pressure type braking system again realizes fluid.
