In this specification, "in one embodiment" does not mean the same embodiment, nor is it an independent or alternative embodiment that excludes other embodiments.

[0024] Embodiments

[0025] Reference Figures 1-4 For the embodiments of the present application, the embodiments provide an energy storage battery charging port device with protection function, which can realize the effect of opening the protection plate 204 without using screwdrivers and other tools, and locking the protection plate 204 without screws.

[0026] Energy storage battery 100;

[0027] It should be noted that the model of the energy storage battery 100 is 3EVF200, the capacity is 6V 200Ah, and the size is 267*180*270mm.

[0028] The protection mechanism 200 comprises a hollow rotating disc 201 fixedly installed on the top of the energy storage battery 100 through a bearing, a plurality of limiting grooves 202 respectively arranged on the surface of the hollow rotating disc 201, a limiting rod 203 arranged on the inner wall of the limiting groove 202, a protection plate 204 rotatably sleeved on the outer surface of the limiting rod 203, a plurality of fixed rods 205 fixedly connected to the top of the energy storage battery 100 and matched with the protection plate 204, and a positioning assembly 206 arranged on the outer side of the hollow rotating disc 201.

[0029] It should be noted that the hollow rotating disc 201 is coincided with the center of the charging port T, and when the hollow rotating disc 201 rotates counterclockwise, the limiting rod 203 can be driven to move through cooperation with the limiting groove 202, so that the limiting rod 203 drives the protection plate 204 to rotate with the fixed rod 205 as the center, and a plurality of protection plates 204 form a closed circle to cover the charging port T, thereby protecting the charging port T.

[0030] Specifically, the plurality of limiting grooves 202 are arranged in a circumferential array on the surface of the hollow rotating disc 201, and the outer surface of the limiting rod 203 is in sliding contact with the inner wall of the limiting groove 202.

[0031] Further, the plurality of limiting grooves 202 are arranged in a circumferential array on the inner side of the hollow rotating disc 201, and the inner surface of the protection plate 204 is in rotational contact with the outer surface of the fixed rod 205.

[0032] Preferably, the positioning assembly 206 comprises a fixed plate 206a fixedly connected to the top of the energy storage battery 100, and a spring 206b fixedly installed on the outer surface of the fixed plate 206a.

[0033] It should be noted that the positioning assembly 206 further comprises a pawl 206c fixedly connected to the other end of the spring 206b, and a fixed column 206d fixedly installed on the top of the energy storage battery 100 and matched with the pawl 206c.

[0034] Further, the positioning assembly 206 further comprises a ratchet wheel 206e engaged with the outer surface of the pawl 206c, a connecting shaft 206f fixedly connected to the inner surface of the ratchet wheel 206e, a gear 206g fixedly sleeved on the outer surface of the connecting shaft 206f, and a rack 206h engaged with the outer surface of the gear 206g.

[0035] Further, when the connecting shaft 206f rotates clockwise, the ratchet wheel 206e and the gear 206g can be driven to rotate synchronously, and through cooperation of the gear 206g and the rack 206h, the hollow rotating disc 201 is driven to rotate counterclockwise, and when the connecting shaft 206f reversely rotates, the ratchet wheel 206e is blocked by the pawl 206c, so that the connecting shaft 206f cannot rotate.

[0036] Specifically, the inner surface of the pawl 206c is in rotational contact with the outer surface of the fixed column 206d, the outer end surface of the connecting shaft 206f is fixedly installed on the outer surface of the energy storage battery 100 through a bearing, and the inner side surface of the rack 206h is fixedly connected with the outer side surface of the hollow rotating disc 201.

[0037] In use, rotating the connecting shaft 206f clockwise drives the ratchet 206e and the gear 206g to rotate synchronously, the hollow rotating disc 201 is driven to rotate counterclockwise through the cooperation of the gear 206g and the rack 206h, the limiting rod 203 is driven to move through the cooperation of the hollow rotating disc 201 and the limiting groove 202, the protective plates 204 are driven to rotate around the fixed rod 205 by the limiting rod 203, and a plurality of protective plates 204 form a closed circle to cover the charging port T, so as to protect the charging port T.

[0038] When the charging port T needs to be used, the pawl 206c is pushed away from the ratchet 206e to a position where the pawl 206c is out of contact with the ratchet 206e, and the spring 206b is given a pressure, the connecting shaft 206f is rotated counterclockwise, the gear 206g is driven to rotate synchronously, the hollow rotating disc 201 is driven to rotate clockwise through the cooperation of the gear 206g and the rack 206h, the limiting rod 203 is driven to move through the cooperation of the hollow rotating disc 201 and the limiting groove 202, the protective plates 204 are driven to rotate around the fixed rod 205 by the limiting rod 203, and the covering of the charging port T is simultaneously opened.

[0039] In summary, through the cooperation between the components in the protection mechanism 200, the user can quickly open and close the protective plates 204 by hand without the help of any tools, and the protective plates 204 do not need to be fixed by screws, which reduces the risk of water and dust entering and improves the safety and service life of the charging port T.
