Description

Technical Field

[0001] The utility model relates to the technical field of unmanned aerial vehicles, in particular to a protective structure for a power supply plug of a plant protection unmanned aerial vehicle. Background Art

[0002] In modern agricultural production, plant protection drones have become an important agricultural machinery and equipment. They can spray farmland efficiently and accurately, greatly improving agricultural production efficiency. However, during use, since the power plug is exposed to the outside, it is easily affected by environmental factors such as dust and moisture, resulting in poor contact or even short circuit of the plug, affecting the normal operation of the drone. In addition, it is necessary to frequently replace batteries and replenish pesticides. Improper operation during the loading process will splash the liquid medicine onto the power plug at the aircraft end. The pollution of liquid medicine and dust increases the safety hazards of operations. In mild cases, the plug will be corroded, reducing operating efficiency and service life. In severe cases, a short circuit accident will occur, causing a fire source with serious consequences. In order to solve the above problems, it is urgent to design a protective structure for the power plug of the plant protection drone. Utility Model Content

[0004] The technical solution of the utility model is achieved in this way:

[0005] A power plug protection structure for a plant protection UAV comprises an aircraft end plug and a battery end socket. The aircraft end plug is provided with a power plug and a guide column. The outer wall of the aircraft end plug is slidably provided with a protective sliding cover. A baffle is provided at one end of the protective sliding cover. The baffle and the protective sliding cover form a protective cavity. The baffle is provided with a plurality of through holes for the power plug and the guide column to pass through. The side wall of the protective sliding cover is slidably engaged with the aircraft end plug. When the protective sliding cover slides to the farthest distance relative to the aircraft end plug, the power plug is placed in the protective cavity.

[0006] Furthermore, a positioning column is provided on the inner side of the baffle, a spring is sleeved on the outer side of the positioning column, and a blind hole for accommodating the spring is provided on the aircraft end plug. By providing the positioning column and the spring, the aircraft end plug can be effectively prevented from shaking and loosening during transportation, thereby improving the stability and reliability of the protective sliding cover.

[0017] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0018] like Figures 1 to 4 As shown, an embodiment of the utility model provides a power plug protection structure for a plant protection UAV, including an aircraft end plug 6 and a battery end socket 1, the aircraft end plug 6 is provided with a power plug and a guide column 12, the outer wall of the aircraft end plug 6 is slidably provided with a protective slide 4, one end of the protective slide 4 is provided with a baffle 14, the baffle 14 and the protective slide 4 form a protection cavity, the baffle 14 is provided with a plurality of through holes for the power plug and the guide column 12 to pass through, the side wall of the protective slide 4 is slidably engaged with the aircraft end plug 6, and when the protective slide 4 slides to the farthest distance relative to the aircraft end plug 6, the power plug is placed in the protection cavity.

[0019] During use, the power plug is aligned with the battery terminal socket 1 through the guide column 12, and the battery terminal socket 1 presses down the protective slide 4, so that the power plug is inserted into the battery terminal socket 1 to achieve the power connection of the drone. When the battery terminal socket 1 needs to be replaced or removed, the battery terminal socket 1 is pulled out, and the protective slide 4 is slid to place the power plug in the protective cavity. The protective slide 4 is kept fixed by the friction between the inner wall of the protective slide 4 and the outer side of the aircraft terminal plug 6, so as to achieve the effect of protecting the power plug. A protective cavity is formed by the baffle 14 and the protective slide 4, and the power plug is placed therein, so as to protect the power plug from the external environment in the non-working state, avoid damage or contamination during use, and improve the safety and convenience of operation.

[0020] The through hole includes a power hole 10 for the power plug to pass through and a guide hole 9 for the guide column 12 to pass through. A fluororubber sealing ring 3 is fixedly arranged in the power hole 10, and a sliding bearing 2 is fixedly arranged in the guide hole 9. By providing the fluororubber sealing ring 3, it is possible to effectively prevent liquid medicine or dust from penetrating into the power hole 10, thereby improving the protective performance of the protective slide cover 4 on the power plug. By fixing the sliding bearing 2 in the guide hole 9, the friction between the guide column 12 and the guide hole 9 can be reduced, thereby improving the movement efficiency and service life.

[0021] A positioning column 13 is provided on the inner side of the baffle 14, and a spring 5 is sleeved on the outer side of the positioning column 13. A blind hole 11 for accommodating the spring 5 is provided on the aircraft end plug 6. When the battery end socket 1 is installed, the battery compresses the spring 5 under the action of its own gravity, so that the power plug extends out of the power hole 10. When the battery is removed, the battery end socket 1 is pulled out, the spring is restored, and the baffle 14 is pushed to place the power plug in the protective cavity. By providing the positioning column 13 and the spring 5, the shaking and loosening of the aircraft end plug during transportation can be effectively prevented, and the stability and reliability of the protective slide cover 4 can be improved. The spring 5 can be accommodated through the blind hole 11, making the entire structure more compact and easy to install and maintain.

[0022] The end of the positioning column 13 is placed in the blind hole 11, and the distance between the end of the positioning column 13 and the bottom of the blind hole 11 is greater than the sliding distance of the protective slide 4. By placing one end of the positioning column 13 in the blind hole 11, the positioning column 13 is prevented from being unable to enter the blind hole 11 due to deformation of the spring 5. By setting the distance between the end of the positioning column 13 and the bottom of the blind hole 11 to be greater than the sliding distance of the protective slide 4, it can be ensured that when the protective slide 4 slides, the positioning column 13 will not contact the bottom of the blind hole 11, thereby preventing the power plug from being unable to fully extend.

[0023] The side wall of the protective slide 4 is provided with an oblong hole 8, the length direction of the oblong hole 8 is the same as the sliding direction of the protective slide 4, and the side wall of the aircraft end plug 6 is threadedly connected with a fastening screw 7, and when the protective slide 4 slides, the fastening screw 7 slides in the oblong hole 8. By providing the oblong hole 8, the fastening screw 7 can slide along the oblong hole 8 when the protective slide 4 slides, thereby limiting the sliding distance of the protective slide 4. The fastening bolt 7 connected by thread can facilitate the removal of the protective slide 4.

[0024] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
