Referring to fig. 1, an embodiment of the present invention provides an access device 100, the access device 100 is used for storing an object 200 and locking the object 200, so that the object 200 is fixed inside the access device 100, and the access device 100 can also unlock the object 200 inside the access device 100, so that the object 200 can be taken out from the access device 100, wherein the object 200 may be a mobile power source or other mobile electronic devices.

Referring to fig. 2-3, the access device 100 includes a housing 10, a locking mechanism 20, and a limiting structure 30. The housing 10 is provided with a receiving cavity 101, and the receiving cavity 101 is used for receiving the object 200. The locking mechanism 20 includes a lock arm 21, a first elastic member 22, and a memory alloy 23. The two lock arms 21 are rotatably mounted to the housing 10, respectively, and one ends of the two lock arms 21 are rotatable with respect to the housing 10 toward or away from the object 200 about respective rotational axes, respectively. The first elastic element 22 is connected with the two locking arms 21, two ends of the memory alloy 23 are respectively connected with the two locking arms 21, the first elastic element 22 is used for providing elastic force and enabling one end of each locking arm 21 to abut against the object 200 so as to lock the object 200, and the memory alloy 23 is used for driving one end of each locking arm 21 to rotate away from the object 200 so as to unlock the object 200. The limiting structure 30 is fixed to the housing 10, and the limiting structure 30 is used for respectively limiting one end of each of the two locking arms 21 to a limit position when the one end of each of the two locking arms 21 is rotated away from the object 200, so that when the memory alloy 23 drives the one end of each of the two locking arms 21 to rotate away from the object 200, the two locking arms 21 can cooperatively unlock the object 200 under the limitation of the limiting structure 30.

When the memory alloy 23 is not driven, the elastic force provided by the first elastic element 22 makes one end of the locking arm 21 abut against the object 200 and maintain a locked state, and at this time, the object 200 can be locked in the accommodating cavity 101. In the driving process of the memory alloy 23, the memory alloy 23 overcomes the elastic force of the first elastic piece 22 to do work, and one end of the locking arm 21 rotates around the rotation axis of the locking arm 21 away from the object 200 until the two locking arms 21 unlock the object 200 and keep the unlocked state, and at the moment, the object 200 can be taken out of the accommodating cavity 101.

It should be noted that, one end of the locking arm 21 refers to an end of the locking arm 21 directly contacting the object 200, and in the process that one ends of the two locking arms 21 respectively rotate around the respective rotation axes away from the object 200, the object 200 can be taken out only after the object 200 is completely unlocked only when the two locking arms 21 release the locking of the object 200. However, since there is a difference in the rotational resistance of each of the two lock arms 21 and the memory alloy 23 is linearly contracted by energization, there is only rotation of the lock arm 21 having a small rotational resistance and no rotational motion of the lock arm 21 having a large rotational resistance.

In this embodiment, by providing the limiting structure 30, the two locking arms 21 can cooperatively unlock the object 200 under the limitation of the limiting structure 30. Specifically, during the driving process of the memory alloy 23, the memory alloy 23 is electrified and contracted, the locking arm 21 with smaller rotation resistance rotates away from the object 200 to the opposite limit position first, and then the locking of the object 200 is released, and meanwhile, the locking arm 21 with smaller rotation resistance is limited by the limiting structure 30 to continue rotating away from the object 200. At this time, the memory alloy 23 continues to contract to drive the locking arm 21 with larger resistance, so that the locking arm 21 with larger rotation resistance releases the locking of the object 200 after rotating away from the object 200 to the corresponding limit position, and meanwhile, the locking arm 21 with larger rotation resistance is limited by the limit structure 30 to continue rotating away from the object 200, at this time, both the locking arms 21 release the locking of the object 200, and thus the cooperative unlocking of the object 200 is completed.

The embodiment of the utility model provides an access arrangement 100, through setting up limit structure 30, eliminated two locking arms 21 because of the rotation resistance variation in size and/or the rotation difference that the drive power variation in size that memory alloy 23 exported respectively two locking arms 21, realized two locking arms 21 to the unblock in coordination of object 200, prevent that two locking arms 21 can not relieve the locking to object 200 completely and cause object 200 to lock and die in holding chamber 101, make locking arm 21 can unlock object 200 sensitively, simple structure and effect are showing.

It can be understood that after the object 200 enters the accommodating cavity 101, the two locking arms 21 respectively abut against the two opposite outer side walls of the object 200, so that the object 200 is locked in the accommodating cavity 101 under the clamping of the two locking arms 21, and it is difficult to ensure that the object 200 is completely locked in the accommodating cavity 101 by the friction force generated between the locking arms 21 and the object 200. Therefore, in order to increase the locking degree between the object 200 and the locking arm 21, as shown in fig. 2, in this embodiment, two outer side walls of the object 200 that are opposite to each other are provided with two locking grooves 201 respectively matched with one ends of the two locking arms 21, when the object 200 is accommodated in the accommodating cavity 101, the two locking grooves 201 respectively correspond to one ends of the two locking arms 21, and one ends of the two locking arms 21 can be respectively fastened to the two locking grooves 201, so that the object 200 cannot move along the length direction of the accommodating cavity 101, thereby ensuring that the object 200 is completely locked in the accommodating cavity 101.
