[0027] 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. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present utility model.

[0028] Refer to Figures 1 - 7 , an embodiment provided by the present utility model: an outdoor AGV automatic charging pile protection device, including a support component 1, the support component 1 includes a rear side plate 101 and a front side plate 107, a connecting rod 102 is fixedly connected between the rear side plate 101 and the front side plate 107, the connecting rod 102 passes through the driving frame 601 and is slidably connected to each other. The number of the connecting rods 102 is four. An adaptation hole 106 and an accommodating channel 104 are provided on the front side plate 107. A contact switch 1 103 is fixedly installed at the lower part of the rear side plate 101, and a contact switch 2 105 is fixedly installed at the lower part of the front side plate 107;

[0029] Refer to Figure 6, the support component 1 can provide support and installation positions for the whole, and the contact switch 1 103 and the contact switch 2 105 are used for switch actions in extreme positions.

[0030] On the front side plate 107, the electric push rod 1 2 and the electric push rod 2 3 are fixedly installed. In front of the support component 1, there is a charging head device 5. The charging head device 5 includes a charging head 501. The rear part of the charging head 501 is fixedly connected with a driving frame 504. The rear part of the driving frame 504 is fixedly connected with a light rod 505. The number of light rods 505 is two. The light rods 505 pass through the matching holes 106 and are slidably connected to each other. A wire channel 503 is reserved at the rear part of the charging head 501. A charging electrode plate 502 is arranged at the front part of the charging head 501. The electric push rod 1 2 drives the charging head device 5 to extend and retract. The output end of the electric push rod 1 2 passes through the front side plate 107 and is fixedly connected with the driving frame 504;

[0031] Reference Figure 5 , Figure 7 , during the charging operation, the electric push rod 1 2 is powered on to work, driving the driving frame 504 to move. The driving frame 504 drives the charging head 501 and the charging electrode plate 502 to move, so that part of the charging head 501 extends out, facilitating the connection and charging between the charging electrode plate 502 and the AGV.

[0032] Above the charging head device 5, there is a protection component 6. The electric push rod 2 3 drives the protection component 6 to extend and retract; the protection component 6 includes a driving frame 601. A protective cover 602 is fixedly connected to the driving frame 601. The longitudinal section shape of the protective cover 602 is U-shaped with the opening facing downwards and is made of a transparent material. The protective cover 602 passes through the accommodation channel 104. An end protector is arranged at the end of the protective cover 602;

[0033] Reference Figure 2 , Figure 3 , Figure 4 , during the protection operation, the electric push rod 2 3 is powered on to work, driving the driving frame 601 to move. The driving frame 601 drives the protective cover 602 to move. The protective cover 602 can extend out prior to the charging head 501, so as to provide a shielding effect for part of the charging head 501, avoiding rainwater and snow from falling on the charging head 501 and playing a protective role in the connected state.

[0034] The end protection member includes a slide bar 603 fixedly installed inside the protective cover 602 and a double-sided electromagnet 606 in the middle. There are two slide bars 603, and they are symmetrically arranged. A end protection plate 604 is slidably connected to the slide bar 603. There are two end protection plates 604. Elastic pads are fixedly connected to the opposite sides of the two end protection plates 604. A clamping spring 6031 is sleeved on the slide bar 603 and outside the end protection plate 604. A strong magnet 605 is fixedly connected to the inner end of the end protection plate 604. The magnetism of the double-sided electromagnet 606 during operation is the same as that of the strong magnet 605.

[0035] Reference Figure 2 , Figure 3 , Figure 4 , when about to connect, the double-sided electromagnet 606 is powered on and operates. Magnetic forces are generated on both sides of the double-sided electromagnet 606. Since the magnetism of the double-sided electromagnet 606 during operation is the same as that of the strong magnet 605, a repulsive force is generated, which can push the end protection plate 604 to move outward, squeezing the clamping spring 6031, providing a channel for the connection of the charging electrode plate 502 on the charger head 501. When the connection is completed, the double-sided electromagnet 606 stops operating and the magnetic force disappears. Under the elastic force of the clamping spring 6031, the connection part can be clamped, thus ensuring good protection during the charging state.

[0036] By providing the support assembly 1 and the protection assembly 6, before the charger head 501 extends out, the protective cover 602 can be driven to extend out, which can block rain and snow and prevent rain from falling on the charger head 501. Moreover, the end protection plate 604 can provide protection in the retracted state and the connected state, and the protection effect is good.

[0037] Working principle: When in use, the support component 1 can provide support and installation positions for the whole. The first contact switch 103 and the second contact switch 105 are used for switch actions in extreme positions. The second electric push rod 3 is energized to work, driving the driving frame 601 to move. The driving frame 601 drives the protective cover 602 to move. The protective cover 602 can extend prior to the charging head 501, so as to provide a shielding effect for the charging head 501 part, preventing rainwater and snow from falling on the charging head 501 and playing a protective role in the connected state; when about to connect, the double-sided electromagnet 606 is energized to work, and magnetic forces are generated on both sides of the double-sided electromagnet 606. Since the magnetism of the double-sided electromagnet 606 during operation is the same as that of the strong magnet 605, a repulsive force is generated, so as to push the end guard plate 604 to move outward, squeezing the clamping spring 6031, providing a channel for the connection of the charging electrodes 502 on the charging head 501. Then the first electric push rod 2 is energized to work, driving the driving frame 504 to move. The driving frame 504 drives the charging head 501 and the charging electrodes 502 to move, making the charging head 501 part extend, facilitating the connection and charging between the charging electrodes 502 and the AGV. When connected, the double-sided electromagnet 606 stops working and the magnetic force disappears. Under the elastic force of the clamping spring 6031, the connected part can be clamped, thus ensuring good protection in the charging state.

[0038] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
