Embodiment 1

[0032] Such as figure 1 with figure 2 As shown, the present invention provides a charger with full charge and automatic power-off, comprising: a housing 1, an installation cavity 11 is provided inside the housing 1, and the installation cavity 11 has a first inner surface 111 and a The second inner surface 112; the automatic power-off switch 2, the automatic power-off switch 2 is arranged in the installation cavity 11, and the upper end of the automatic power-off switch 2 stops against the first inner surface 111; the buffer assembly 3. The buffer assembly 3 includes an elastic support 31 and a guide 32, one end of the elastic support 31 is supported by the automatic power-off switch 2, and the other end of the elastic support 31 is supported by the second The inner surface 112 , the guide piece 32 is disposed on the second inner surface 112 , the guide piece 32 cooperates with the automatic power-off switch 2 to limit the moving direction of the automatic power-off switch 2...

Embodiment 2

[0037] The difference between this embodiment and the foregoing embodiment is:

[0038]In some embodiments of the present invention, the elastic supporting member 31 includes a supporting plate 311 and a supporting spring 312, the supporting plate 311 is supported on the lower end of the automatic power-off switch 2, and the supporting spring 312 is supported on the between the support plate 311 and the second inner surface 112 . Thus, by supporting the elastic force of the spring 312, the automatic power-off switch 2 is stopped against the first inner surface 111, thereby reducing the distance that the automatic power-off switch 2 moves relative to the housing 1, so as to improve the inner surface of the housing 1. The stability of the automatic power-off switch 2, to avoid loose connection between the wire and the automatic power-off switch 2,

[0039] Preferably, in one of the preferred technical solutions of this embodiment, the support plate 311 is provided with a slidin...

Embodiment 3

[0044] The difference between this embodiment and the above embodiments is that in some embodiments of the present invention, the guide member 32 includes a first guide flange 322, and the first guide flange 322 has a first guide groove 3221, and the automatic The lower end of the power-off switch 2 is slidably disposed in the first guide groove 3221 , and the outer wall of the automatic power-off switch 2 is slidably matched with the inner wall of the first guide groove 3221 . Thereby, the moving direction of the automatic cut-off switch 2 is guided.

[0045] Preferably, in one of the preferred technical solutions of this embodiment, the outer wall of the automatic power-off switch 2 is provided with a limit flange 21, and the limit flange 21 cooperates with the guide 32 to limit The displacement of the automatic power-off switch 2. It can be understood that, during the movement of the automatic power-off switch 2, the limit flange 21 first contacts the guide member 32, so a...

Abstract

The invention provides a charger capable of automatically powering off after full charging, which is characterized in that a shell is internally provided with a mounting cavity, and the mounting cavity is provided with a first inner surface and a second inner surface; an automatic power-off switch is arranged in the mounting cavity, and the upper end of the automatic power-off switch abuts againstthe first inner surface; a buffer assembly comprises an elastic supporting piece and a guide piece, one end of the elastic supporting piece is supported on the automatic power-off switch, the other end of the elastic supporting piece is supported on the second inner surface, the guide piece is arranged on the second inner surface, and the guide piece is matched with the automatic power-off switchto limit the moving direction of the automatic power-off switch. The elastic supporting piece is arranged between the automatic power-off switch and the second inner surface, so that when the automatic power-off switch moves relative to the shell, the automatic power-off switch abuts against the first inner surface through the elastic force of the elastic supporting piece, the moving distance ofthe automatic power-off switch relative to the shell is reduced, and the stability of the automatic power-off switch in the shell is improved.

Description

technical field [0001] The invention relates to the technical field of chargers, in particular to a charger with automatic power-off when fully charged. Background technique [0002] In the related technologies of electric vehicle chargers, an automatic power-off switch is usually installed in the circuit of the electric vehicle charger, and the on-off of the charger is controlled by the automatic power-off switch, so that after the battery of the electric vehicle is fully charged, the Open the circuit to achieve the purpose of protecting the battery, but because the charger needs to be placed on the electric vehicle, when the electric vehicle is driving on a bumpy road, the automatic power-off switch may collide with the charger shell in the charger, thereby Affect the stability of the charger and affect the stability of the connection between the lead and the automatic power-off switch. [0003] Therefore, it is necessary to develop a charger with full automatic power-off...
