The present application claims the benefit of Chinese Patent Application No. 202210338690.6 filed on Apr. 1, 2022, the contents of which are incorporated herein by reference in their entirety.
The present application belongs to the technical field of charging equipment, in particular to a charger.
With the increasing functions of electronic devices such as mobile phones and tablet computers, the power consumption of mobile phones increases, and the charging frequency also increases. The existing Chinese, American and Japanese standard chargers are limited by the size of internal components and the size of charger case, and limited by the requirements of safety regulations on creepage distance. This makes the two sides perpendicular to the plug insertion direction, one side being more than 19.3 cm and the other side being more than 27.2 cm, relatively large in both length and width dimensions, and thus very inconvenient to carry. And when in use, the relative position of the pin and the charger body is fixed, which causes great inconvenience when used in sockets with different receptacle directions.
Aiming at the problem of inconvenient use caused by the fixed relative position between the existing pin and the charger body, a charger is provided.
In order to solve the above technical problems, the embodiments of the present application provide a charger, which includes a charger body, a plug and a tooth ring;
Optionally, the positioning part includes a positioning main body and a plurality of outer teeth arranged on the positioning main body, and the clamping groove is formed between the outer teeth and surface of the positioning main body and between two adjacent outer teeth.
Optionally, the positioning main body is provided with a first side and a second side arranged oppositely, and both the first side and the second side are provided with the outer teeth; the clamping teeth includes a first clamping tooth and a second clamping tooth, the first clamping tooth is clamped in the clamping groove on the first side, and the second clamping tooth is clamped in the clamping groove on the second side.
Optionally, the plug further includes a rotating part connected between the connecting part and the positioning part;
Optionally, an annular groove is arranged in the middle of the rotating part, and an edge of the connecting hole is arranged in the annular groove.
Optionally, the tooth ring is provided with a flange, the second cavity is provided with a limit groove, and the flange is arranged in the limit groove.
Optionally, the charger body includes an upper cover and a lower cover connected in snap-fit, the upper cover is provided with a first groove, a second groove and a first spacer plate for separating the first groove and the second groove, the lower cover is provided with a third groove, a fourth groove and a second spacer plate for separating the third groove and the fourth groove; the first groove and the third groove form the first cavity, the second groove and the fourth groove form the second cavity, and the first spacer plate and the second spacer plate form the spacer plate.
Optionally, the charger further includes a left pendulum block rotatably connected to the upper cover and a right pendulum block rotatably connected to the lower cover;
Optionally, the left pendulum body is provided with a first pin slot, and the right pendulum body is provided with a second pin slot, and the pin can be hidden in a cavity formed by the first pin slot and the second pin slot.
Optionally, the left pendulum body is provided with a left avoidance groove, and the right pendulum body is provided with a right avoidance groove, when the left pendulum block and the right pendulum block swing to a fully unfolded state, a distance between the left avoidance groove and the right avoidance groove is greater than a length of the connecting part, so as to avoid hitting the rotating connecting part.
The charger provided by the embodiments of the application is light and thin overall, and is convenient to carry and pack. The plug can rotate at certain angles, and the plug can be positioned at the position of the angle by clamping the clamping tooth in the clamping groove; a plurality of clamping grooves are provided, so that rotation of the plug at multiple angles can be realized, and the pin can be inserted into a charging socket at any rotation angles without affecting usage effect of the charger.
Reference signs in the drawings are as follows:
In order to make the beneficial effects, technical solutions and technical problems solved by the present application clearer, the present application will be further illustrated in detail with reference to the drawings and embodiments. It should be understood that the specific embodiments described here are merely for illustrating the present application, not for limiting the present application.
As shown in
The plug 1 includes a connecting part 11, a positioning part 12 and a pin 13; the upper surface of the connecting part 11 exposes the receiving cavity, and the pin 13 is installed on the upper surface of the connecting part 11. One end of the positioning part 12 is connected to the lower surface of the connecting part 11, and another end of the positioning part 12 extends into the central through hole of the tooth ring 2, so that the positioning of the plug 1 is realized through the tooth ring 2 and the positioning part 12.
Specifically, the central through hole of the tooth ring 2 is provided with a clamping tooth, the positioning part 12 is provided with a plurality of clamping grooves 123, and when the plug 1 in the receiving cavity is rotated, the clamping tooth is clamped into one of the clamping grooves 123 to limit rotation angle of the plug 1.
According to the charger provided by the embodiment of the application, the plug 1 can rotate at certain angles, and the plug 1 can be positioned at the position of the angle by clamping the clamping tooth in the clamping groove 123; a plurality of clamping grooves are provided, so that rotation of the plug 1 at multiple angles can be realized, and the pin 13 can be inserted into a charging socket at any rotation angles without affecting usage effect of the charger. Moreover, the charger is relatively light and easy to carry and pack.

The right pendulum block 8 includes a right pendulum body 81, a right gear 82 and a right rotating shaft 83. The right gear 82 is installed on the right pendulum body 81, the right rotating shaft 83 is installed on the right gear 82, and the left rotating shaft 73 and the right rotating shaft 83 extend in opposite directions. A right rotating groove 45 is arranged on the inner surface of the lower cover 4, and the right gear 82 and the right rotating shaft 83 are arranged in the right rotating groove 45.
The left gear 72 meshes with the right gear 82. Rotate the left pendulum block 7 or the right pendulum block 8, the left pendulum block 7 and the right pendulum block 8 can rotate simultaneously to expose or hide the pin 13. The maximum rotation angle of the left pendulum block 7 and the right pendulum block 8 is 90°. In this case, the left pendulum block 7 and right pendant block 8 swing to a fully unfolded state, the charger is in a usable state, the plug 1 can be rotated, and when the left pendulum block 7 and right pendulum block 8 swing back to the initial position, the pin 13 is hidden between the left pendulum block 7 and right pendulum block 8.
In this embodiment, the thickness of the charger is small. In the charging process, when user touches the position closest to the pin of the charger body, the creepage distance is short, which does not meet the safety requirements. By setting the left pendulum block 7 and right pendulum block 8, the creepage distance is increased when fully unfolded, which can prevent the user from touching unsafe positions and thus improve safety.
As shown in
In an embodiment, the left pendulum body 71 is provided with a left avoidance groove 712, and the right pendulum body 81 is provided with a right avoidance groove 812. When the left pendulum block 7 and the right pendulum block 8 swing to a fully unfolded state, the left avoidance groove 712 and the right avoidance groove 812 are recessed away from the plug 1. The concave directions of the left avoidance groove 712 and the right avoidance groove 812 are opposite. The distance between the left avoidance groove 712 and the right avoidance groove 812 is slightly longer than the length of the connecting part 11, so as to avoid hitting when the connecting part 11 rotates, and without blocking the connecting part 11.
The above descriptions are only preferred embodiments of the present application and are not intended to limit the present application. Any modifications, equivalent substitutions and improvements made within the spirit and principle of the present application shall be included in the protection scope of the present application.
