In the above embodiment, the male plug a of the automobile is plugged into a socket (not labeled) so that the male plug a is butted against the female plug 120, thereby electrically connecting the male plug a and the female plug 120 to each other. If the user backs a car and keeps away from charging pile under the prerequisite of not pulling out public plug A, under the pulling force effect of public plug A for the pulling force that connecting piece 220 bore exceeds the work interval. The connector 220 is disengaged from the base 110 so that the male plug a pulls the protective housing 210 and the connector 220 together away from the base 110. Thereby can avoid pulling down to fill electric pile and cause serious accident loss.
It should be emphasized that the link 220 is used to connect the protection seat 210 and the base 110, and when the pulling force applied to the link 220 exceeds the working range, the link 220 is completely (or partially) separated from the base 110, so that the protection seat 210 and the base 110 are far away from each other. And the connectors 220 satisfying the above conditions may satisfy all the requirements. For example, the connecting member 220 may be broken under a tensile force exceeding the working range, and the protective seat 210 and the base 110 can be moved away from each other without limitation after the connecting member 220 is broken.
In some embodiments, the connecting member 220 includes a connecting piece 221 and a plurality of pressing portions 222, the connecting piece 221 is fixedly connected to the protective base 210, the plurality of pressing portions 222 are arranged along a circumferential direction of the connecting piece 221, the pressing portions 222 and the base 110 press an outer edge of the connecting piece 221, and when the connecting member 220 is subjected to a pulling force exceeding a working range, the connecting piece 221 deforms to separate from the pressing of the pressing portions 222 and the base 110.
In the above embodiment, when the pulling force applied to the connecting member 220 exceeds the working range, the connecting member 221 is deformed and bent, so that the connecting member 220 is forced to be separated from the clamping of the clamping portion 222 and the base 110.

By inserting the protection bolt 2221 through the notch 2211 and screwing a protection screw hole (not labeled), the contact area between the protection bolt 2221 and the connection piece 221 can be increased, so that the clamping portion 222 and the base 110 can clamp the connection piece 220 more stably.
It is understood that any embodiment that can secure the connection piece 221 and the protection seat 210 is possible, such as welding or clamping. In one embodiment, the connecting piece 221 has a plurality of fastening screws 2212, the protecting base 210 has a plurality of matching holes 212 corresponding to the fastening screws 2212, and the protecting base 210 further has a plurality of fastening bolts 213 corresponding to the matching holes 212, wherein the fastening bolts 213 pass through the matching holes 212 and are screwed with the fastening bolts 213.
In the above embodiment, since the connecting piece 221 and the protection base 210 are connected by a bolt, the bolt connection may connect the connecting piece 221 and the protection base 210 more firmly than a snap connection. In contrast to the welding connection method, the bolt connection method may replace the connection piece 221, so that the connection piece 221 may be replaced with a new one after the connection piece 221 is deformed.
In a specific embodiment, the base 110 includes a base body 111 and a transition seat 112, the female plug 120 is mounted on the base body 111, the transition seat 112 is detachably mounted on the base body 111, and the connecting member 220 is connected to the transition seat 112. The transition seat 112 and the connecting member 220 are used for connection, and the female plug 120 is mounted on the base body 111. When the connecting element 220 is under tension, the transition seat 112 will directly bear the acting force of the connecting element 220, and if the transition seat 112 is damaged by the tension, the transition seat 112 can be replaced. The problem that the whole base 110 is difficult to repair due to the damage of the pulling force is avoided.
In the above embodiment, the base 110 further includes the sealing gasket 113, and the sealing gasket 113 is interposed between the base body 111 and the transition seat 112. So that the sealability between the base body 111 and the transition seat 112 can be secured to protect the electrical components in the base 110.
In some preferred embodiments, the anti-pulling protection mechanism further includes an electronic control assembly 300, the electronic control assembly 300 includes a position sensor 310 and a power supply module (not shown), the position sensor 310 is mounted on the base 110 to detect the relative position between the base 110 and the connecting member 220, the power supply module (not shown) is electrically connected to the position sensor 310 to obtain the relative position information between the base 110 and the connecting member 220, when the connecting member 220 is connected to the base 110, the power supply module (not shown) supplies power to the female plug 120, and when the connecting member 220 is separated from the base 110, the power supply module (not shown) stops supplying power to the female plug 120.
In the above embodiment, when the connecting element 220 is pulled away from the base 110, the position sensor 310 senses the information and transmits the information to the power supply module (not shown) in the form of an electrical signal, and the power supply module (not shown) stops supplying power to the female plug 120, thereby reducing the risk of electric shock. It should be noted that, the position sensor 310 may be a sensor with a suitable specification and model according to actual needs, as long as it can accurately determine whether the connecting element 220 is detached from the base 110. Meanwhile, the power supply module (not shown) should include a control circuit and a power supply, and it is a conventional electric control means that the power supply module (not shown) controls whether to supply power to the female plug 120 according to the electric signal of the position sensor 310, and the power supply module (not shown) is not described in detail herein.
It is contemplated that male plug a may be secured during normal charging so that male plug a maintains a mated condition with female plug 120. In one embodiment, the protection seat 210 further has a clamping portion (not shown), a first state of clamping the male plug a in the socket (not shown), and a second state of allowing the male plug a to enter and exit the socket (not shown).
In a preferred embodiment, the base 110 further includes a guiding block 114, the guiding block 114 is located between the socket (not labeled) and the female plug 120, and the guiding block 114 defines a guiding hole 1141 for the male plug a to pass through. After the male plug a is butted through the guiding hole 1141, the male plug a can be properly aligned with the female plug 120, which facilitates the butting of the male plug a and the female plug 120.
In addition, the invention also provides a charging pile which is provided with the anti-pulling protection mechanism for the charging pile.
First, the clamping portion (not labeled in the figure) is adjusted to the second state, the male plug a of the automobile is plugged into the plug interface (not labeled in the figure), and then the male plug a is butted through the guiding hole 1141 and then can be aligned with the female plug 120, so that the male plug a is butted with the female plug 120, and the male plug a and the female plug 120 are electrically connected with each other. The clamping portion (not labeled in the figure) can be adjusted to the first state, so that the male plug A is fixed. If the user backs a car and keeps away from charging pile under the prerequisite of not pulling out public plug A, under the pulling force effect of public plug A for the pulling force that connecting piece 220 bore exceeds the work interval. The connection piece 221 is deformed and bent, so that the connection member 220 is forcibly separated from the clamping of the clamping portion 222 and the base 110. Thereby disengaging the connector 220 and the shield seat 210 from the base 110.
The connector 220 is disengaged from the base 110 so that the male plug a pulls the protective housing 210 and the connector 220 together away from the base 110. Thereby can avoid drawing down to fill electric pile and cause serious accident loss.
