Embodiment Construction

[0085] The present invention is further illustrated below by means of examples, but the present invention is not limited thereto within the scope of examples.

[0086] This embodiment discloses a protection lock mechanism for unlocking and locking the battery pack. refer to Figure 1-4 It should be understood that the protection lock mechanism 10 includes a lock pin 102 , a power pin 103 , a first electromagnetic induction element 104 and a first elastic element 105 . Wherein, the locking pin 102 can be switched between an extended state and a retracted state. The power pin 103 acts on the lock pin 102 , and the power pin 103 can move relative to the lock pin 102 to engage with or separate from the lock pin 102 . The first electromagnetic induction element 104 is disposed on the power pin 103 , and the first electromagnetic induction element 104 is used to drive the power pin 103 to apply force to the lock pin 102 along the retraction direction of the lock pin 102 under the ...

Abstract

The invention discloses a protection lock mechanism. The protection lock mechanism comprises a lock pin, a power pin and a first electromagnetic induction element. The power pin acts on the lock pin and can move relative to the lock pin so as to be connected with or separated from the lock pin. The first electromagnetic induction element is arranged on the power pin and used for driving the power pin to apply acting force to the lock pin in the retraction direction under the action of external electromagnetic equipment. The lock pin is provided with an executing part and a connecting part, the connecting part is connected to one end of the executing part, the connecting part is provided with a first accommodating cavity, and the first accommodating cavity is used for accommodating the power pin. A first inclined part is arranged on the inner wall face of the first accommodating cavity, and a second inclined part matched with the first inclined part is arranged at the head end of the power pin. When the first electromagnetic induction element is attracted with the external electromagnetic equipment, acting force is applied to the lock pin in the retraction direction, so that the lock pin is in a retraction state. According to the protection lock mechanism, the lock pin retracts in an electromagnetic mode, and efficiency and reliability are both high.

Description

[0001] This application is a divisional application of a Chinese patent application with an application date of December 29, 2017, an application number of 2017114788589, and an invention titled "protection lock mechanism". technical field [0002] The invention relates to a protection lock mechanism. Background technique [0003] The protection lock mechanism is a protection device commonly used in daily life. For example, when a door is closed, in order to reliably close the door, it is usually necessary to use a protection lock mechanism. The protection lock mechanism includes a lock pin that can be extended and retracted. Wherein, when the lock pin is in an extended state, the door can be reliably closed; when the lock pin is in a retracted state, the door can be opened. [0004] However, the protection lock mechanism in the prior art usually switches the protection lock mechanism between the extended state and the retracted state manually or mechanically, so that the e...
