[0032] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present application.

[0033] As Figures 1 to 7 shown, the present application provides an end cover assembly 20, including a base 21 and a cover 22; the base 21 has a groove 211, a charging interface 212 and an insertion channel 213, and the charging interface 212 and the insertion channel 213 are provided on the groove wall of the groove 211; the cover 22 includes a flexible cover 221, and the flexible cover 221 can be hermetically covered or opened for the groove 211, and the flexible cover 221 has a connection buckle 23, and the connection buckle 23 is movably inserted into the insertion channel 213 and can limit the flexible cover 221 from detaching from the insertion channel 213.

[0034] When the cover 22 is opened, the charging interface 212 located on the groove 211 can be exposed to allow an external power source to be electrically connected to the charging interface 212, thereby realizing the charging function; in addition, due to the setting of the connection buckle 23, the flexible cover 221 can be prevented from detaching from the base 21. When the cover 22 is hermetically covered to the groove 211, the cover 22 can seal the charging interface 212, thereby preventing external liquid from invading the charging interface 212; it can also prevent dirt from being generated at the charging interface 212, thereby avoiding poor contact and potential safety hazards.

[0035] In this embodiment, as Figures 2 to 7As shown, the specific structure of the base 21 is not strictly limited; the end of the base 21 is recessed to form a groove 211. Among them, the charging interface 212 and the insertion channel 213 are both located on the bottom wall of the groove 211. The charging interface 212 can be electrically connected to an external power source to realize the charging function, and further elaboration is not required here. An installation hole 214 is formed in the bottom wall of the groove 211; at least part of the charging interface 212 is located in the installation hole 214 and is fixed in the installation hole 214 by means of snap connection or gluing. One end of the insertion channel 213 away from the groove wall of the groove 211 is open, and the end cover assembly 20 further includes a sealing plug 24. The sealing plug 24 seals the opening of the insertion channel 213 to prevent liquid from invading the interior of the appliance through the insertion channel 213. The cover 22 and the sealing plug 24 together ensure the waterproof safety during the use of the end cover assembly 20.

[0036] In this embodiment, as Figures 3 to 7 shown, the flexible cover 221 has a plate-like structure; the flexible cover 221 has two opposite sides, one side facing the groove 211 and the other side facing away from the groove 211. The flexible cover 221 is made of a flexible material so that the flexible cover 221 can have a certain flexibility; for example, materials such as silica gel. The outer periphery of the flexible cover 221 has a sealing lip 2211, and the sealing lip 2211 is in sealing cooperation with the side wall of the groove 211 to seal the opening of the groove 211. The sealing lip 2211 is continuously arranged around the outer periphery of the flexible cover 221; when the flexible cover 221 seals the opening of the groove 211, the sealing lip 2211 is in interference fit with the side wall of the groove 211.

[0037] In this embodiment, as Figures 5 to 7 shown, the connecting buckle 23 is generally in a long strip shape; one end of the connecting buckle 23 is attached to the flexible cover 221, and the other end is inserted into the insertion channel 213. The connecting buckle 23 is adjacent to the outer edge of the flexible cover 221 to facilitate the flipping action of the flexible cover 221. Specifically, the connecting buckle 23 includes a connecting section 231 and a limiting head 232; the connecting section 231 is attached to the flexible cover 221 and is movably inserted into the insertion channel 213; the limiting head 232 is attached to one end of the connecting section 231 facing away from the flexible cover 221 and protrudes laterally from the connecting section 231; the insertion channel 213 has a limiting surface 2131, the limiting surface 2131 faces away from the groove 211, and the limiting head 232 can abut against the limiting surface 2131 to limit the connecting buckle 23 from disengaging from the insertion channel 213.

[0038] In this embodiment, as Figures 5 to 7As shown, the connecting section 231 is in a long strip structure; one end of the connecting section 231 is connected to the flexible cover 221, and the other end extends away from the flexible cover 221. The connecting section 231 is flexibly arranged; during the process of the flexible cover 221 flipping, the connecting section 231 can be deformed, so as to facilitate the flexible cover 221 to perform the flipping action. The connecting section 231 and the flexible cover 221 are integrally arranged to strengthen the connection strength between the connecting section 231 and the flexible cover 221, and also reduce the difficulty of the processing technology of the connecting section 231 and the flexible cover 221.

[0039] In this embodiment, if Figures 5 to 7 As shown, the size of the stopper 232 is larger than the size of the entrance of the insertion channel 213 close to the groove wall, so that the stopper 232 cannot easily pass through the insertion channel 213. In order to allow the stopper 232 to enter the insertion channel 213, the stopper 232 is flexibly configured; the stopper 232 can deform itself to pass over the entrance of the insertion channel 213 and enter the insertion channel 213, so as to facilitate the assembly of the stopper 232 into the insertion channel 213. Among them, the stopper 232 and the connecting section 231 are integrally configured to strengthen the connection strength between the connecting section 231 and the stopper 232, and also reduce the difficulty of the processing technology of the connecting section 231 and the stopper 232.

[0040] In this embodiment, if Figures 5 to 7 As shown, the connecting buckle 23 further includes a pulling section 233, which is connected to the side of the limiting head 232 away from the connecting section 231; the pulling section 233 is used to pull the limiting head 232 into the insertion channel 213. When the connecting buckle 23 and the insertion channel 213 are assembled, the pulling section 233 is first extended into the insertion channel 213, and then extends from the end of the insertion channel 213 away from the groove 211, so that the end of the pulling section 233 is exposed outside the insertion channel 213, and the user can pull the pulling section 233 to deform the limiting head 232 to enter the insertion channel 213.

[0041] In this embodiment, if Figures 5 to 7As shown, the traction section 233 is generally in a long strip shape; in order to enable the traction section 233 to extend into the insertion channel 213 and be exposed outside the insertion channel 213, the length of the traction section 233 is greater than the length of the insertion channel 213. After the connecting buckle 23 is assembled with the insertion channel 213, due to the long length of the traction section 233, it may interfere with the sealing plug 24 to block the insertion channel 213; therefore, after the traction limit head 232 enters the insertion channel 213, the traction section 233 can be separated from the limit head 232. The user can cut or break the traction section 233 to separate the traction section 233 from the limit head 232. Among them, the traction section 233, the connecting section 231 and the limit head 232 are integrally arranged to strengthen the connection strength between the traction section 233, the connecting section 231 and the limit head 232, and at the same time can reduce the processing difficulty of the traction section 233, the connecting section 231 and the limit head 232.

[0042] In this embodiment, as Figures 3 to 7 shown, the cover 22 further includes a support cover 222, and the support cover 222 is stacked on the flexible cover 221 to strengthen the support strength of the flexible cover 221. The support cover 222 is made of hard rubber so that the support cover 222 has a certain support strength to support the flexible cover 221. Among them, the support cover 222 is generally in a disc shape; and the support cover 222 is stacked on the side of the flexible cover 221 facing away from the groove 211; when the cover 22 seals the opening of the groove 211, the support cover 222 is located in the groove 211. At least a part of the sealing lip 2211 in the flexible cover 221 is located outside the range of the support cover 222 to ensure that the sealing lip 2211 contacts the side wall of the groove 211. The support cover 222 and the flexible cover 221 are formed by two-color injection molding to strengthen the connection strength between the support cover 222 and the flexible cover 221, and at the same time can reduce the processing difficulty between the flexible cover 221 and the support cover 222.

[0043] In this embodiment, as Figures 5 to 7 shown, among the support cover 222 and the flexible cover 221, one of them is provided with a positioning groove 2221, and the other is provided with a positioning boss 2212 that cooperates with the positioning groove 2221; when processing the flexible cover 221 and the support cover 222, by the positioning boss 2212 being located in the positioning groove 2221, the relative position between the flexible cover 221 and the support cover 222 can be determined. Among them, the outer contour of the positioning groove 2221 is substantially the same as the outer contour of the positioning boss 2212. In this embodiment, a part of the side of the flexible cover 221 facing the support cover 222 protrudes outward locally to form the positioning boss 2212; a part of the side of the support cover 222 facing the flexible cover 221 is recessed locally to form the positioning groove 2221.

[0044] In this embodiment, as Figures 3 to 7As shown, the cover 22 has a latching groove 220, and the latching groove 220 is exposed outside the groove 211; the latching groove 220 facilitates the user to operate the cover 22. The user's finger can latch on the latching groove 220 to separate the cover 22 from the groove 211, so as to facilitate the opening or latching of the cover 22.

[0045] The following describes the usage process of the end cap assembly 20:

[0046] When charging is required, the hand acts on the latching groove 220 to lift the cover 22, causing the cover 22 to rotate around the connecting buckle 23 in the insertion channel 213 to open the charging interface 212 in the groove 211. During this process, the connecting buckle 23 moves along the insertion channel 213 until the limiting head 232 abuts against the limiting surface 2131.

[0047] When it is necessary to cover the groove 211, the hand presses the cover 22, causing the cover 22 to rotate around the connecting buckle 23 in the insertion channel 213 until the flexible cover 21 in the cover 22 closes the opening of the groove 211 to seal the charging interface 212. During this process, the connecting buckle 23 moves along the insertion channel 213.
