The movement of the first locking member 20 can drive the second locking member 30 to move relative to the fixed body 10, so that when the first base 21 is reset from the first retracted position to the first engaged position, the second base 31 is reset from the second engaged position to the second retracted position.

When the locking mechanism 100 is in the first locked state, the first locking end 211 is configured to cooperate with the chip 2000, and the chip 2000 is configured to be mounted on the base 200, the chip 2000 presses the elastic conductive member 302, and the chip 2000 is electrically connected to the circuit board 301 through the elastic conductive member 302.

In the embodiment of the present application, the chip 2000 as an example of the mounted object may be mated with the first locking end 211 or the second locking end 311, wherein the first locking end 211 is for mating with the chip 2000 in a state where the locking mechanism 100 is in the first locking state, the chip 2000 is configured to press the elastic conductive member 302 against the upward elastic force of the elastic conductive member 302 when the chip 2000 is mounted to the base 200, and the electrical contacts of the lower surface of the chip 2000 are electrically connected with the circuit board 301 through the elastic conductive member 302; in the case where the locking mechanism 100 is in the second locking state, the second locking end 311 is configured to cooperate with the chip 2000, the second locking end 311 is configured to restrict the movement of the chip 2000 in a direction away from the elastic conductive member 302 by the upward elastic force of the elastic conductive member 302 when the chip 2000 is detached, and the chip 2000 is at least partially separated from the elastic conductive member 302.

The base 200 is a basic mounting member of the electronic device 1000, which may provide a mounting basis for the components of the locking mechanism 100, the circuit board assembly 300, the chip 2000, and the like. Optionally, the locking mechanism 100, the circuit board assembly 300, and the chip 2000 are located on one side of the base 200.

The circuit board assembly 300 amplifies, filters, and analog-to-digital converts the electrical signal generated by the chip 2000, and may further transmit the processed signal to a peripheral device such as a computer for signal analysis to implement base recognition, which may also be performed in a control module on the circuit board 301. The circuit board assembly 300 includes a circuit board 301 and an elastic conductive member 302, wherein the circuit board 301 is disposed on the base 200, and the elastic conductive member 302 is connected to the circuit board 301.

The contacts on the chip 2000 are connected to the elastic conductive member 302, so that each contact needs to be accurately positioned and fixed, and meanwhile, due to the characteristics of precision and vulnerability of the chip 2000, especially in the biochip 2000 such as the sequencing chip 2000 with the amphiphilic molecule film, the amphiphilic molecule film is very easy to break, so that the sequencing is invalid, therefore, when the chip 2000 is taken out from the electronic device 1000, the phenomenon that the chip 2000 is excessively sprung up by the elastic conductive member 302 to cause severe vibration needs to be reduced.

In an embodiment of the application, the chip 2000 may be a biochip 2000, alternatively, the chip 2000 may be a sequencing chip 2000, such as a nanopore sequencing chip 2000. The sequencing chip 2000 may have a microstructure array formed by microstructure units, where an amphiphilic molecule film for embedding a protein nanopore is formed on the microstructure units, where the amphiphilic molecule film separates the microstructure units into an upper chamber and a lower chamber, and the protein nanopore is the only channel between the upper chamber and the lower chamber. During sequencing, analytes such as DNA molecules can move from one chamber through the nanopore to another under the drive of electric field forces, which can cause the electrical signal generated by the chip 2000 to fluctuate as four different bases of DNA molecules pass through the nanopore, thereby enabling recognition of the different bases.

As shown in fig. 5 and 6, in an exemplary process of mounting the chip 2000 on the electronic device 1000, the end edge of the chip 2000 moving downward presses the first locking end 211 at the first engaging position, so that the first base 21 moves toward the first avoiding position, at this time, the expansion member 40 is deformed by shrinkage, and at the same time, the second locking end 311 rotates toward the chip 2000 based on the engagement of the first pin shaft 32 and the second pin shaft 33, at this time, the end edge of the chip 2000 has rotated downward from above and passed the second locking end 311, and is not engaged with the second locking end 311 protruding from the fixing body 10, and the first locking end 211 is continuously pressed until the chip 2000 is aligned with the first base 21, which means that the chip 2000 is connected to the elastic conductive member 302, the end edge of the chip 2000 has rotated downward from above and passed the first locking end 211, and the first base 21 is reset to the first engaging position under the action of the expansion member 40, so that the first locking end 211 is engaged with the chip 2000, so that the chip 2000 is mounted in place.

When the key cap 50 is released, based on the resilience force of the telescopic member 40 after shrinking, the first base 21 is driven to return to the first matching position along the arrangement direction x, the first locking end 211 abuts against the chip 2000 which is at least partially far away from the elastic conductive member 302, so as to form a certain support for the chip 2000, the second base 31 rotates anticlockwise relative to the fixed body 10, the second base 31 rotates to the second avoiding position, and the second locking end 311 avoids the detaching track of the chip 2000, so that the chip 2000 can be taken out directly.
