A compact charger with foldable prongs

Abstract

This invention provides a compact charger with foldable prongs, including a linkage between a plug structure and a cable retracting structure. When the cable retracting structure is pushed inward, it extends to pull the plug structure into the charger's interior, thus retracting the charger's prongs, reducing the charger's size, and preventing exposed prongs from scratching other objects. The invention also includes an unfolding structure with two movable strips. Two movable strips are rotatably connected to the two movable strips, and a return spring is positioned between them.

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0024] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," "fixing," and "equipped with" should be interpreted broadly.

Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0025] Referring now to the accompanying drawings, the various figures are intended only to illustrate certain exemplary embodiments and are not intended to limit the scope of the invention. In the various figures, the same reference numerals denote the same or corresponding parts. The dimensions and scales in the various figures are also for illustrative purposes only and should not be construed as limiting the scope of the invention; these dimensions may be enlarged relative to actual products.

[0026] Reference Figure 1-3 The present invention relates to a compact charger with foldable plugs, comprising a charger structure 1, wherein a stretching structure 2 is provided inside the charger structure 1.

[0027] The stretching structure 2 includes a plug structure, a take-up structure, and an extension structure. The plug structure is located on one side of the charger structure 1, and the take-up structure is located on the other side of the charger structure 1. An unfolding structure is provided between the plug structure and the take-up structure. The unfolding structure includes a moving strip 209, with rotating strips 208 rotatably connected to both ends of the moving strip 209. The rotating strips 208 are rotatably connected to the plug structure and the take-up structure. Two moving strips 209 are provided, and a return spring 210 is provided between the two moving strips 209. In the above-mentioned technical method... In this design, the plug structure includes an auxiliary strip 201, with plug bodies 202 disposed on both sides of the outer wall of the auxiliary strip 201. The plug bodies 202 are slidably connected to the positioning groove 105. The auxiliary strip 201 is rotatably connected to the rotating strip 208. The cable winding structure includes a lifting ring 203, with a rotating ring 211 rotatably connected to the bottom of the lifting ring 203. The rotating ring 211 is rotatably connected to the rotating strip 208. A positioning shaft 204 is disposed inside the lifting ring 203. Auxiliary grooves 205 are provided on both sides of the lifting ring 203. A take-up reel 206 is rotatably connected to the outer wall of the positioning shaft 204. A planar spiral spring is provided between the positioning shaft 204 and the take-up reel 206. A charging cable 207 is provided on the outer wall of the take-up reel 206. When the charger structure 1 is needed, the plug body 202 is inserted into the socket, and the charging cable 207 is connected to the device for charging. When the charger body 101 needs to be stored, the charging cable 207 is released, and then the planar spiral spring drives the take-up reel 206 to rotate. The take-up reel 206 drives the charging cable 207 to be drawn into the outer wall of the take-up reel 206, and then downwards. Pushing the positioning shaft 204 causes the rotating bar 208 to rotate, which in turn causes the moving bar 209 to move outward. The moving bar 209 then stretches the return spring 210 and causes the bottom rotating bar 208 to rotate, which in turn causes the auxiliary bar 201 to move inward. The auxiliary bar 201 then causes the plug body 202 to be retracted into the charger body 101. Afterward, the auxiliary groove 205 passes through the insertion shaft 108 and is rotated, causing the insertion shaft 108 to engage with the top of the lifting ring 203, thus completing the storage.

[0028] Furthermore, in the above technical solution, the charger structure 1 includes a charger body 101, an installation chamber 102 is provided inside the charger body 101, heat-conducting strips 103 are provided on both sides of the installation chamber 102, heat dissipation holes 104 are provided on the outer wall of the charger body 101, a positioning groove 105 is provided at the bottom of the charger body 101, a connecting ring 106 is provided at the top of the charger body 101, a limiting ring 107 is provided at the top of the connecting ring 106, and insertion shafts 108 are provided on both sides of the top of the limiting ring 107. During the use of the charger body 101, gas can enter and exit through the heat dissipation holes 104, and then the heat-conducting strips 103 absorb the internal heat during the gas flow, and the gas flow drives the heat on the surface of the heat-conducting strips 103.

[0029] The above-described embodiments are merely illustrative of certain implementations of this utility model, and their descriptions are relatively specific and detailed. However, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
