DETAILED DESCRIPTION

[0021] The following will be combined with the accompanying drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this utility model, not all of them. Based on the embodiments in this application, all other embodiments obtained by ordinary technical personnel in this field without making creative efforts are within the scope of protection of this utility model.

[0022] Reference Figure 1-Figure 3 The utility model provides an electric vehicle charging gun power assist mechanism, including a connector 1, an outer shell 2 and a panel 3. The outer shell 2 is installed in the charging pile, and the connector 1 is slidably and lifted in the outer shell 2. The panel 3 is rotatably installed on the outer wall of one side of the outer shell 2 through a second rotating shaft 6. At least one set of trigger components 4 for driving the connector 1 to rise and fall is installed between the panel 3 and the outer shell 2, and the connecting end of the connector 1 can extend out of the top wall of the outer shell 2 and be electrically connected to a power supply such as a power bank in the charging pile. In this embodiment, two sets of trigger components 4 are symmetrically installed to improve the stability of the movement of the connector 1.

[0023] Reference Figure 1-Figure 3The trigger assembly 4 includes a connecting rod 41 and a torsion spring 42. One end of the connecting rod 41 is rotatably connected to the side wall of the panel 3 through a rotating shaft 5. The other end of the connecting rod 41 is slidably mounted on the side wall of the outer shell 2 and is movably connected to the connector 1. A vertical waist-shaped groove 211 for sliding the connecting rod 41 is opened on the outer wall of the outer shell 2. One end of the torsion spring 42 is hooked on the outer wall of the rotating shaft 5. A positioning shaft 7 is fixed on the outer wall of the outer shell 2 on the side of the vertical waist-shaped groove 211 away from the panel 3. The positioning shaft 7 is arranged close to the top wall of the outer shell 2 and is located obliquely above the rotating shaft 5. The other end of the torsion spring 42 is hooked on the outer wall of the positioning shaft 7. When the panel 3 is in the normal state, it is parallel to the outer shell 2, and the connecting end of the connector 1 is in the state of extending out of the outer shell 2. When performing the disconnection operation, the user only needs to pull the panel 3 to rotate, and then drive the connecting rod 41 to press the connector 1 through the panel 3, so that the connector 1 slides to the side extending into the outer shell 2. At this time, the torsion spring 42 is stretched to obtain elastic potential energy. When the operation is completed, the user only needs to release the panel 3, the torsion spring 42 returns to its original state and drives the panel 3 and the connector 1 to automatically reset.

[0024] Furthermore, a sliding portion 411 is provided on the side of the connecting rod 41 facing the outer shell 2, and the sliding portion 411 passes through the vertical waist-shaped groove 211 and is inserted into the connector 1, and then the limited sliding of one end of the connecting rod 41 is realized by the cooperation between the sliding portion 411 and the vertical waist-shaped groove 211. A movable groove 11 is provided on the outer wall of the connector 1, and the sliding portion 411 can move in the movable groove 11 at any angle and distance in the upward, downward, left and right directions to adapt to the movement of the connecting rod 41.

[0025] Furthermore, a limit plate 8 is integrally formed on the side wall of the outer shell 2 , and a limit groove 81 is formed on the limit plate 8 to limit the movement of the connecting rod 41 and the torsion spring 42 , thereby ensuring the stability of the trigger assembly 4 during operation.

[0026] Reference Figure 1-Figure 3 In a further embodiment, a seal 9 is installed on the outer wall of the outer shell 2 in synchronization with the sliding movement of the connecting rod 41. A sliding groove 212 for slidingly limiting the seal 9 is integrally formed on the outer wall of the outer shell 2. The sliding portion 411 is penetrated by the seal 9. The seal 9 is used to block the vertical waist-shaped groove 211 to reduce the possibility of rainwater and debris entering the outer shell 2 and causing damage. The vertical waist-shaped groove 211 will only be briefly exposed for a period of time when the panel 3 is operated.

[0027] Reference Figure 2 and Figure 3In a further embodiment, the outer shell 2 includes a main shell 21 and a back cover 22.
