[0049] The directional words appearing in the following description are all directions shown in the figures, and do not limit the specific structure of the embodiments of this application. In the description of this application, it should also be noted that, unless otherwise clearly specified and limited, the terms "assembly" and "connection" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be directly connected or indirectly connected. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to the specific circumstances.

[0050] To solve the existing technical problems, the present invention provides a locking mechanism and electronic device for locking a component to be installed in place. To better understand the present invention, the locking mechanism and electronic device of the present invention are described in detail below with reference to Figures 1 to 9.

[0051] The following first introduces the locking mechanism provided in the embodiment of the present application for locking the installed part in place.

[0052] Please refer to FIG1 , which is a schematic exploded view of the structure of the locking mechanism according to an embodiment of the present application.

[0053] As shown in FIG1 , the present application provides a locking mechanism 100 for locking a component to be installed in place. The locking mechanism 100 includes a fixed body 10, a first locking member 20, and a second locking member 30. The first locking member 20 is connected to the fixed body 10 and is movable relative to the fixed body 10. The first locking member 20 includes a first base 21. The first base 21 has a first locking end 211 at one end thereof proximal to the second locking member 30. The first base 21 is movable relative to the fixed body 10. The second locking member 30 is connected to the first locking member 20 and the fixed body 10. Movement of the first locking member 20 drives the second locking member 30 to move relative to the fixed body 10. The second locking member 30 includes a second base 31. The second base 31 has a second locking end 311 at one end thereof distal to the first locking member 20. When the locking mechanism is in the first locking state, the first locking end 211 is configured to engage with the component to be installed, while the second locking end 311 is configured to avoid the component to be installed. When the locking mechanism is in the second locking state, the second locking end 311 is used to cooperate with the part to be installed, and the first locking end 211 avoids the part to be installed.

[0054] The fixed body 10 is the basic mounting component of the locking mechanism 100, providing a mounting base for components such as the first locking member 20 and the second locking member 30. The fixed body 10 can have a variety of shapes, including regular shapes such as a cuboid, cube, or cylinder, or other irregular shapes. The fixed body 10 can also be manufactured from a variety of materials, such as plastic, metal, graphite, or ceramic.

[0055] The locking mechanism 100 has two locking states. When the locking mechanism 100 is in the first locking state, the first locking end 211 engages with the part to be installed, and the second locking end 311 avoids the part to be installed. When the locking mechanism 100 is in the second locking state, the second locking end 311 engages with the part to be installed, and the first locking end 211 avoids the part to be installed. During the transition between the two locking states of the locking mechanism 100, the positions of the first locking member 20 and the second locking member 30 both change, and the first locking member 20 and the second locking member 30 can also lock the part to be installed in different positions. In the locked state, one of the first locking end 211 and the second locking end 311 engages with the part to be installed to interfere with the installation and removal trajectory of the part to be installed, while the other avoids the part to be installed to avoid interfering with the installation and removal trajectory of the part to be installed. The engagement method can be a snap connection or abutment.

[0056] Specifically, the first locking member 20 includes a first base 21 and a first latching end 211 disposed at one end of the first base 21 near the second locking member 30. The first latching end 211 is the primary portion of the first locking member 20 for contacting the component to be mounted. The specific structural dimensions of the first base 21 and the first latching end 211, as well as the connection method therebetween, are not limited in this embodiment of the present application. For example, the first base 21 and the first latching end 211 are integrally formed. The first base 21 can be positioned in a first mating position and a first avoidance position. In the first mating position, the first latching end 211 interferes with the installation / removal trajectory of the component to be mounted, thereby mating with the component to be mounted. In the first avoidance position, the first latching end 211 avoids the component to be mounted, i.e., the first latching end 211 does not interfere with the installation / removal trajectory of the component to be mounted, and thus, does not interfere with the installation / removal process of the component to be mounted.

[0057] Specifically, the second locking member 30 is connected to the first locking member 20 and the fixed body 10. Movement of the first locking member 20 drives the second locking member 30 to move relative to the fixed body 10. The second locking member 30 includes a second base 31 and a second latching end 311 disposed at an end of the second base 31 away from the first locking member 20. The second latching end 311 is the main portion of the second locking member 30 that contacts the component to be mounted. The specific structural dimensions of the second base 31 and the second latching end 311, as well as the connection method therebetween, are not limited in this embodiment of the present application. For example, the second base 31 and the second latching end 311 are integrally structured. When the first base 21 is in the first matching position, the second base 31 is in the second avoidance position, and the second locking end 311 avoids the part to be installed, that is, the second locking end 311 does not interfere with the installation and removal trajectory of the part to be installed, that is, the second locking end 311 will not interfere with the installation and removal process of the part to be installed; when the first base 21 is in the first avoidance position, the second base 31 is in the second matching position, and the second locking end 311 interferes with the installation and removal trajectory of the part to be installed and can therefore be matched and connected with the part to be installed.

[0058] In the locking mechanism 100 provided in the embodiment of the present application, the locking mechanism 100 includes a fixed body 10, a first locking member 20 and a second locking member 30. The first locking member 20 includes a first base 21 and a first locking end 211 arranged at one end of the first base 21, and the second locking member 30 includes a second base 31 and a second locking end 311 arranged at one end of the second base 31. The first locking member 20 and the second locking member 30 are movably arranged on the fixed body 10. When the locking mechanism 100 is in the first locking state, the first locking end 211 is used to cooperate with the part to be installed, and the second locking end 311 avoids the part to be installed. When the locking mechanism 100 is in the second locking state, the second locking end 311 is used to cooperate with the part to be installed, and the first locking end 211 avoids the part to be installed. By designing the first locking member 20 and the second locking member 30, the installation and removal process of the part to be installed can be adjusted as needed, and the connection stability between the part to be installed and the locking mechanism 100 can be improved. In addition, the first locking member 20 and the second locking member 30 cooperate to control the movement of the part to be installed, so that the part to be installed stops at a predetermined position, which can slow down the movement, reduce the defect of the part to be installed moving under adverse conditions, and improve the stability and safety of the part to be installed.

[0059] In some optional embodiments, as shown in Figure 1, the first locking member 20 further includes a telescopic member 40, the telescopic member 40 is disposed at an end of the first base 21 away from the first stop end 211, the telescopic member 40 is connected to the first base 21 and the fixed body 10, and along the arrangement direction of the telescopic member 40 and the first stop end 211, the first base 21 moves relative to the fixed body 10 along an arrangement direction x, the telescopic member 40 is configured to telescope, and when the locking mechanism 100 is not subjected to external force, the telescopic member 40 drives the first stop end 211 to protrude from the fixed body 10. The arrangement direction x in the embodiment of the present application includes two opposite directions, that is, the arrangement direction x includes a direction from the telescopic member 40 to the first stop end 211 and a direction from the first stop end 211 to the telescopic member 40.

[0060] Specifically, the first locking member 20 includes a first base 21 and a telescopic member 40. The fixed body 10 is provided with a blocking portion. One end of the telescopic member 40 is connected to the first base 21, and the other end of the telescopic member 40 is connected to the blocking portion. The blocking portion, the telescopic member 40 and the first base 21 are arranged in sequence along the arrangement direction x. The first locking end 211 is arranged at the end of the first base 21 away from the telescopic member 40. The telescopic member 40 provides a traction force to the first base 21 so that the first base 21 is in the first matching position by default. When the first base 21 is placed in the first avoidance position by an external force, the telescopic member 40 is subjected to the external load and is in a state of contraction and deformation. When the external force disappears or decreases, the first base 21 moves toward the first matching position along the arrangement direction x based on the rebound force (thrust) after the telescopic member 40 is contracted. It can be understood that when the external force disappears, the first base 21 is driven by the telescopic member 40 to return from the first avoidance position to the first matching position. The movement of the first locking member 20 can drive the second locking member 30 to move relative to the fixed body 10. Therefore, when the first base 21 is reset from the first avoidance position to the first matching position, the second base 31 is reset from the second matching position to the second avoidance position.

[0061] Optionally, the telescopic member 40 is selected from at least one of a linear spring, a torsion spring, a spring, a solid elastic rubber, a porous elastic rubber, a solid elastic plastic, a porous elastic plastic, a memory metal and a magnetic component.

[0062] In some embodiments of the present application, the first locking member 20 includes at least two telescopic members 40 , which are respectively connected to the first base 21 and the fixed body 10 , and the two telescopic members 40 are spaced apart along the end of the first base 21 .

[0063] In these optional embodiments, the telescopic member 40 provides traction to the first base 21. When the locking mechanism 100 is in the second locking state, the telescopic member 40 is in a contracted deformation due to the external load. After the external load disappears, based on the rebound force (thrust) after the telescopic member 40 contracts, the locking mechanism 100 is driven to the first locking state, that is, the first base 21 and the second base 31 are automatically reset, thereby reducing the operation of the locking mechanism 100 and improving the degree of automation of the locking mechanism 100.

[0064] In some optional embodiments, as shown in FIG1 , the fixed body 10 is provided with a hollow cavity 14. The locking mechanism 100 further includes a keycap 50, which includes a key portion 51 and a connecting portion 52. The key portion 51 is connected to the connecting portion 52. The key portion 51 protrudes from the fixed body 10. The connecting portion 52 extends through the hollow cavity 14 and is connected to the first base 21. The connecting portion 52 is movable within the hollow cavity 14 along the arrangement direction x.

[0065] In an embodiment of the present application, the fixed body 10 is provided with a hollow cavity 14, and the keycap 50 includes a button portion 51 and a connecting portion 52, one end of the connecting portion 52 passes through the hollow cavity 14 and is connected to the first base 21, and the other end of the connecting portion 52 is connected to the button portion 51, and the connecting portion 52 can move relative to the fixed body 10 along the arrangement direction x in the hollow cavity 14 to drive the first base 21 to move relative to the fixed body 10 along the arrangement direction x, and the button portion 51 protrudes from the fixed body 10 to facilitate operation of the keycap 50, so as to drive the keycap 50 to move in the hollow cavity 14 of the fixed body 10 by applying an external force to the button portion 51.

[0066] Specifically, a boss is provided on one end of the connecting portion 52 facing away from the key portion 51, and an inwardly recessed portion is provided on the end of the first base 21 facing the keycap 50, and the boss and the recess are engaged with each other.

[0067] In some optional embodiments, as shown in Figure 1, when the locking mechanism 100 is in the first locking state, the first base 21 is in the first mating position, and when the locking mechanism 100 is in the second locking state, the first base 21 is in the first avoidance position; the first base 21 is arranged on one side of the fixed body 10, and the first base 21 is provided with a limiting groove 22 extending along the arrangement direction x, and a surface of the fixed body 10 facing the first base 21 is provided with a limiting protrusion 11 protruding toward the first base 21, and the limiting protrusion 11 extends into the limiting groove 22, and the limiting protrusion 11 limits the first base 21 to limit the movement range of the first base 21 between the first mating position and the first avoidance position along the arrangement direction x.

[0068] In an embodiment of the present application, the first base 21 is provided with a limiting groove 22 extending along the arrangement direction x. Optionally, the limiting groove 22 is located at an end of the first base 21 away from the telescopic member 40. It can be understood that the limiting groove 22 is located at the first locking end 211. A surface of the fixed body 10 facing the first base 21 is provided with a limiting protrusion 11 protruding toward the first base 21. The limiting protrusion 11 extends into the limiting groove 22. The first base 21 moves relative to the fixed body 10 along the arrangement direction x. Accordingly, the limiting protrusion 11 and the first base 21 undergo relative motion. When the first base 21 moves to the first mating position, the limiting protrusion 11 engages with the limiting groove 22 to limit the movement of the first base 21, allowing the first base 21 to move along the arrangement direction x to the first mating position. In addition, based on the restriction of the telescopic member 40, the first base 21 moves along the arrangement direction x to the first avoidance position. It can be understood that the first base 21 can reciprocate between the first mating position and the first avoidance position.

[0069] In these optional embodiments, such a configuration allows the movement position of the first base 21 to be limited through the cooperation of the limiting protrusion 11 and the limiting groove 22, which not only simplifies the overall structure of the locking mechanism 100, but also makes the locking mechanism 100 easy to process and manufacture, thereby reducing the manufacturing cost of the locking mechanism 100.

[0070] In some optional embodiments, as shown in Figure 1, the second base 31 is connected to the first base 21, and the second base 31 is rotatably connected to the fixed body 10, wherein when the first base 21 moves along the arrangement direction x between the first mating position and the first avoidance position, the second base 31 rotates relative to the fixed body 10 between the second mating position and the second avoidance position.

[0071] Specifically, the second base 31 is connected to the first base 21 and is rotatably connected to the fixed body 10. When the first base 21 is in the first mating position, the first base 21 and the second base 31 are perpendicular to each other. When the first base 21 is in the first avoidance position, the first base 21 and the second base 31 are arranged at an acute angle. During the movement of the first base 21 from the first mating position to the first avoidance position, the first base 21 drives the second base 31 to rotate relative to the fixed body 10, that is, the second base 31 rotates from the second avoidance position to the second mating position, thereby causing the first retaining end 211 to engage with the component to be mounted to transform into the second retaining end 311 engaging with the component to be mounted, and causing the first retaining end 211 to interfere with the mounting and removal trajectory of the component to be mounted to interfere with the second retaining end 311. The interference with the mounting and removal trajectory of the component to be mounted can be a change in the deflection angle of the component to be mounted or a change in the movement distance of the component to be mounted.

[0072] In the embodiment of the present application, the second base 31 and the fixed body 10 may be connected in a bearing connection, a pin connection, a hinge connection, etc., so as to realize the rotational connection between the second base 31 and the fixed body 10 .

[0073] In some optional embodiments, as shown in FIG1 , the second base 31 is provided with a through hole 312 and a slide groove 313. The second locking member 30 further includes a first pin 32 and a second pin 33. The first pin 32 passes through the through hole 312 and is connected to the fixed body 10. The second pin 33 passes through the slide groove 313 and is connected to the first base 21. The second pin 33 can move along the slide groove 313.

[0074] In an embodiment of the present application, the second base 31 is provided with a through hole 312 and a slide groove 313, and the through hole 312 and the slide groove 313 are arranged at intervals. Specifically, the slide groove 313 is arranged at a non-zero angle with the arrangement direction x, which can be understood as the angle a between the slide groove 313 and the arrangement direction x is 0<a≤90°. Referring to Figures 7 and 8, the angle a between the slide groove 313 and the arrangement direction x refers to the angle between the slide groove 313 and the direction from the telescopic member 40 to the first locking end 211. Optionally, when the first base 21 is in the first mating position, referring to Figure 7, the first base 21 and the second base 31 are arranged perpendicularly, that is, the slide groove 313 is arranged perpendicular to the arrangement direction x; when the first base 21 is in the first avoidance position, referring to Figure 8, the first base 21 and the second base 31 are arranged at an acute angle, that is, the slide groove 313 is arranged at an acute angle with the arrangement direction x. The second locking member 30 further includes a first pin 32 and a second pin 33. The first pin 32 extends through the through hole 312 and is connected to the fixed body 10. Optionally, the fixed body 10 is provided with a first groove, and the first pin 32 is engaged with the first groove. The first pin 32 cooperates with the through hole 312 to enable the second base 31 to rotate relative to the first pin 32. The second pin 33 extends through the slide groove 313 and is connected to the first base 21. Optionally, the first base 21 is provided with a second groove, and the second pin 33 is engaged with the second groove. The first pin 32 cooperates with the through hole 312, and the second pin 33 can slide along the slide groove 313. Movement of the second pin 33 in the arrangement direction x can cause the second base 31 to rotate relative to the first pin 32, and movement of the first base 21 can drive the second pin 33 to slide within the slide groove 313.

[0075] Specifically, first insert the second pin 33 into the slide groove 313, then fix the second pin 33 into the second groove, and then insert the first pin 32 into the through hole 312, and assemble the connected first base 21, first pin 32, second base 31, and second pin 33 to the fixed body 10, wherein the first pin 32 is fixed to the first groove, and then install the telescopic member 40 so that the telescopic member 40 is connected to the fixed body 10 and the first base 21.

[0076] In some optional embodiments, as shown in FIG1 , the fixing body 10 is provided with a first receiving groove 12, the first pin 32 is connected to the groove wall of the first receiving groove 12, and the second base 31 is at least partially disposed in the first receiving groove 12, wherein when the second base 31 is in the second avoidance position, the second locking end 311 is received in the first receiving groove 12. When the second base 31 is in the second engagement position, the second locking end 311 protrudes from the first receiving groove 12.

[0077] In an embodiment of the present application, the fixed body 10 is provided with a first accommodating groove 12, and the first pin shaft 32 is connected to the groove wall of the first accommodating groove 12. Specifically, first grooves are provided on the two opposite groove walls of the first accommodating groove 12, and the two ends of the first pin shaft 32 are respectively clamped in the two first grooves. When the second base 31 is in the second avoidance position, the second locking end 311 is received in the first accommodating groove 12 to form an avoidance of the installation and removal trajectory of the part to be installed; when the second base 31 is in the second matching position, the second base 31 rotates relative to the fixed body 10, and the second locking end 311 protrudes from the first accommodating groove 12 and interferes with the installation and removal trajectory of the part to be installed to limit the movement of the part to be installed.

[0078] In these optional embodiments, such a configuration not only enables the second base 31 to avoid the installation trajectory of the installation component when the second base 31 is in the second avoidance position, so that the second locking end 311 is accommodated in the first accommodating groove 12, thereby reducing the overall space occupied by the locking mechanism 100, but also enables the second locking end 311 to be protected, thereby extending the service life of the locking mechanism 100.

[0079] In some optional embodiments, as shown in FIG1 , the fixing body 10 is provided with a second receiving groove 13, and the first base 21 is at least partially disposed in the second receiving groove 13. When the first base 21 is in the first engagement position, the first latching end 211 protrudes from the second receiving groove 13. When the first base 21 is in the first avoidance position, the first latching end 211 is received in the second receiving groove 13.

[0080] In an embodiment of the present application, the fixed body 10 is provided with a second accommodating groove 13. When the first base 21 is in the first mating position, the first locking end 211 protrudes from the second accommodating groove 13 and interferes with the installation and removal trajectory of the part to be installed, and can be engaged with the part to be installed. When the first base 21 is in the first avoidance position, the first locking end 211 is received in the second accommodating groove 13 to form an avoidance for the part to be installed.

[0081] In some embodiments, the first base 21 is provided with a second groove, and the two ends of the second pin 33 are respectively engaged with the two second grooves. Specifically, the second pin 33 is first inserted into the slide groove 313, and then the second pin 33 is fixed to the second groove of the first base 21. Then, the first pin 32 is inserted into the through hole 312, and then the first pin 32 is fixed to the first groove of the fixed body 10. Thus, the connected first base 21, the first pin 32, the second base 31, and the second pin 33 are assembled to the fixed body 10. Then, the connecting portion 52 of the keycap 50 is passed through the hollow cavity 14 to connect with the first base 21, and then the telescopic member 40 is installed so that the telescopic member 40 is connected to the fixed body 10 and the first base 21.

[0083] In the second aspect, as shown in Figures 2 to 7, an embodiment of the present application provides an electronic device 1000, which includes a base 200, a locking mechanism 100 according to the above-mentioned method, and a circuit board assembly 300. The locking mechanism 100 is arranged on the base 200. The circuit board assembly 300 includes a circuit board 301 and an elastic conductive member 302, the circuit board 301 is arranged on the base 200, and the elastic conductive member 302 is connected to the circuit board 301. In which, when the locking mechanism 100 is in the first locking state, the first locking end 211 is used to cooperate with the chip 2000. When the chip 2000 is configured to be installed on the base 200, the chip 2000 squeezes the elastic conductive member 302, and the chip 2000 is electrically connected to the circuit board 301 through the elastic conductive member 302. When the locking mechanism 100 is in the second locking state, the second locking end 311 is used to cooperate with the chip 2000. When the chip 2000 is configured to be disassembled from the base 200, the second locking end 311 is used to limit the movement of the chip 2000 in the direction away from the elastic conductive member 302, and the chip 2000 is at least partially separated from the elastic conductive member 302.

[0084] In an embodiment of the present application, the chip 2000, as an example of an object to be installed, can cooperate with the first locking end 211 or the second locking end 311, wherein, when the locking mechanism 100 is in the first locking state, the first locking end 211 is used to cooperate with the chip 2000, and when the chip 2000 is installed on the base 200, the chip 2000 is configured to overcome the upward elastic force of the elastic conductive part 302 to squeeze the elastic conductive part 302, and the electrical contacts on the lower surface of the chip 2000 are electrically connected to the circuit board 301 through the elastic conductive part 302; when the locking mechanism 100 is in the second locking state, the second locking end 311 is used to cooperate with the chip 2000, and when the chip 2000 is removed, the second locking end 311 is used to limit the chip 2000 from moving in a direction away from the elastic conductive part 302 under the action of the upward elastic force of the elastic conductive part 302, and the chip 2000 is at least partially separated from the elastic conductive part 302.

[0085] The base 200 is a basic mounting component of the electronic device 1000 and can provide a mounting base for components such as the locking mechanism 100 , the circuit board assembly 300 , and the chip 2000 . Optionally, the locking mechanism 100 , the circuit board assembly 300 , and the chip 2000 are located on one side of the base 200 .

[0086] The circuit board assembly 300 performs operations such as amplification, filtering, and analog-to-digital conversion on the electrical signals generated by the chip 2000. The processed signals can then be transmitted to a computer or other peripheral device for signal analysis to enable base recognition. This signal analysis can also be performed within a control module on the circuit board 301. The circuit board assembly 300 includes a circuit board 301 and an elastic conductive member 302. The circuit board 301 is disposed on the base 200, and the elastic conductive member 302 is connected to the circuit board 301. Optionally, the circuit board assembly 300 includes multiple elastic conductive members 302, each of which is electrically connected to the circuit board 301. Connecting the contacts on the chip 2000 to the elastic conductive member 302 requires accurate positioning and fixation to ensure good conduction at each contact. At the same time, due to the precision and fragility of the chip 2000, especially in a biochip 2000 such as a sequencing chip 2000 having an amphiphilic film, the amphiphilic film is very easy to break, resulting in sequencing failure. Therefore, when removing the chip 2000 from the electronic device 1000, it is necessary to reduce the phenomenon of the chip 2000 being excessively bounced by the elastic conductive member 302 and causing severe vibration.

[0087] In an embodiment of the present 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. A microstructure array composed of microstructure units may be formed in the sequencing chip 2000. An amphiphilic film is formed on the microstructure unit for embedding the protein nanopore therein. The amphiphilic film separates the microstructure unit into two upper and lower chambers, and the protein nanopore is the only channel between the upper and lower chambers. During sequencing, driven by an electric field force, an analyte such as a DNA molecule can move from one chamber through the nanopore to another. When the four different bases of the DNA molecule pass through the nanopore, the electrical signal generated by the chip 2000 will fluctuate, thereby making it possible to identify the different bases.

[0088] For example, as shown in Figures 5 and 6, during the process of installing the chip 2000 on the electronic device 1000, the edge of one end of the chip 2000 that moves downward squeezes the first stop end 211 that is in the first matching position, so that the first base 21 moves toward the first avoidance position. At this time, the telescopic member 40 is in a contraction deformation, and at the same time, based on the cooperation of the first pin 32 and the second pin 33, the second stop end 311 is rotated toward the chip 2000. At this time, the edge of one end of the chip 2000 has rotated downward from the top and passed the second stop end. The stop end 311 will not be engaged with the second stop end 311 that rotates and protrudes from the fixed body 10. Continue to squeeze the first stop end 211 until the chip 2000 is flush with the first base 21. It can be understood that the chip 2000 is connected to the elastic conductive part 302, and one edge of the chip 2000 has rotated downward from the top through the first stop end 211. The first base 21 is reset to the first mating position under the action of the telescopic part 40, so that the first stop end 211 is engaged with the chip 2000 to install the chip 2000 in place.

[0089] For example, as shown in Figures 7, 8 and 9, during the process of removing the chip 2000 from the electronic device 1000, the keycap 50 is pulled to move along the arrangement direction x, and the keycap 50 drives the first base 21 to move along the arrangement direction x toward the first avoidance position, and the first locking member 20 moves along the arrangement direction x toward the direction away from the chip 2000. At this time, the telescopic member 40 is in a state of contraction and deformation, and the second base 31 moves with the first base 21 through the second pin shaft 33. At the same time, due to the restriction of the first pin shaft 32, the second base 31 rotates clockwise with the first pin shaft 32 as the axis, that is, the second base 31 rotates relative to the fixed body 10. At this stage, the first locking end 211 moves along the arrangement direction x with the first base 21 away from the chip 2000, so that the first stopping end 211 is separated from the chip 2000, so that the chip 2000 as a whole is bounced up under the action of the elastic conductive member 302, but the second stopping end 311 rotates along the direction close to the chip 2000 relative to the fixed body 10 with the second base 31 to above the edge of one end of the chip 2000, and the second base 31 rotates to the second mating position, and the bounced chip 2000 is engaged with the rotating second stopping end 311 to limit the bounced chip 2000 from continuing to move, so that the chip 2000 will not bounce up excessively and the vibration of the chip 2000 is reduced. When the keycap 50 is released, based on the rebound force after the telescopic part 40 contracts, the first base 21 is driven to reset to the first mating position along the arrangement direction x, and the first stopping end 211 presses against the chip 2000 that is at least partially away from the elastic conductive part 302 to form a certain support for the chip 2000. The second base 31 rotates counterclockwise relative to the fixed body 10, and the second base 31 rotates to the second avoidance position. The second stopping end 311 avoids the disassembly track of the chip 2000 to facilitate the direct removal of the chip 2000.

[0090] In an embodiment of the present application, one end of the chip 2000 is connected to the locking mechanism 100, and the other end of the chip 2000 can cooperate with the locking mechanism 100 and other components to achieve the installation and disassembly of the chip 2000 through the locking mechanism 100 and other components.

[0091] In the electronic device 1000 provided in the embodiment of the present application, the electronic device 1000 includes a base 200, a locking mechanism 100 and a circuit board assembly 300. The locking mechanism 100 includes a first locking member 20 and a second locking member 30. The first locking end 211 of the first locking member 20 and the second locking end 311 of the second locking member 30 respectively cooperate with the chip 2000. The first locking member 20 is used for installation and positioning of the chip 2000, and the second locking member 30 is used to limit the bounced chip 2000 to slow down the movement of the chip 2000, so that the chip 2000 does not bounce excessively, reduce the vibration of the chip 2000, and improve the stability and safety of the chip 2000.

[0092] In some optional embodiments, as shown in Figures 2, 4 and 5, the base 200 is provided with a limit member 400, the limit member 400 and the locking mechanism 100 are spaced apart along the arrangement direction x, the chip 2000 is configured to be located between the limit member 400 and the locking mechanism 100, and the chip 2000 and the limit member 400 are detachably connected.

[0093] In an embodiment of the present application, when the chip 2000 is installed on the base 200 , the chip 2000 has a first end and a second end along the arrangement direction, the second end is used to cooperate with the first locking member 20 and the second locking member 30 , and the first end is used to cooperate with the limiting member 400 .

[0094] Exemplarily, when installing the chip 2000, the first end of the chip 2000 is first connected to the limit member 400. At this time, the chip 2000 is tilted relative to the arrangement direction x, and then the second end edge of the chip 2000 moving toward the base 200 is squeezed to squeeze the first locking end 211 in the first mating position, so that the first base 21 moves toward the first avoidance position. At this time, the telescopic member 40 is in a state of contraction and deformation. Until the chip 2000 is flush with the first base 21, under the action of the telescopic member 40, the first base 21 is reset to the first mating position, so that the first locking end 211 is mated with the second end, so that the chip 2000 is installed in place. At the same time, the elastic conductive member 302 on the circuit board 301 is compressed to support the electrical contact of the output signal in the chip 2000, and is connected to the chip 2000 circuit board 301.

[0095] For example, when the chip 2000 is removed, the keycap 50 is pulled to move along the arrangement direction x toward the avoidance position, and the first locking end 211 is separated from the second end. Since the first end of the chip 2000 is connected to the limit member 400, under the elastic force of the elastic conductive member 302, the first end of the chip 2000 is pivoted with the limit member 400 as the pivot to rotate the second end of the chip 2000 upward, and the chip 2000 partially bounces up. The bounced chip 2000 is restricted by the second locking end 311 of the second base 31 linked to the first base 21, thereby limiting the bounce angle of the chip 2000, that is, the acute angle between the chip 2000 and the arrangement direction x is smaller, thereby reducing the problem of severe vibration caused by excessive bounce angle.

[0096] In these optional embodiments, such a configuration allows the degree to which the chip 2000 is lifted to be adjusted simply by controlling the locking mechanism 100, thereby reducing vibrations in the chip 2000. Furthermore, the chip 2000 can be installed and removed quickly and easily, simplifying the operation of the electronic device 1000. Furthermore, the chip 2000 is arranged at an acute angle to the arrangement direction x, meaning that one end of the chip 2000 is lifted, further reducing vibrations caused by the chip 2000 being lifted.

[0097] In some optional embodiments, when the chip 2000 is configured to be disassembled from the base 200, the first base 21 is driven to move from the first mating position to the first avoidance position, and when the chip 2000 is connected to the limit member 400, one end of the chip 2000 rotates with the limit member 400 as a pivot, and when the first base 21 is in the first avoidance position, the other end of the chip 2000 is located between the first locking end 211 and the second locking end 311.

[0098] In an embodiment of the present application, when the chip 2000 is taken out from the base 200, that is, when the chip 2000 is configured to be disassembled from the base 200, the first base 21 is driven to move from the first mating position to the first avoidance position. When the first base 21 is in the first avoidance position and the chip 2000 is connected to the limit member 400, one end of the chip 200 is rotated with the limit member as a pivot until the other end of the chip 200 is located above the first stopping end 211, so that the chip 2000 cannot be re-stuck into the card slot of the chip 200 by the first stopping end 211.

[0099] In some optional embodiments, as shown in Figures 1 and 2, the base 200 is provided with a positioning groove 201, which is used to accommodate at least a portion of the chip 2000. When the locking mechanism 100 is in the first locking state, the first latching end 211 protrudes from the second receiving groove 13 and extends into the positioning groove 201, and the second latching end 311 is received in the first receiving groove 12. When the locking mechanism is in the second locking state, the second latching end 311 protrudes from the first receiving groove 12 and extends into the positioning groove 201, and the first latching end 211 is received in the second receiving groove 13.

[0100] In an embodiment of the present application, the base 200 is provided with a positioning groove 201, and is located between the locking mechanism 100 and the limit member 400. Circuit components are provided at the opposite ends of the positioning groove 201, that is, the layout direction of the two circuit components is perpendicular to the layout direction x. When the chip 2000 is installed on the base 200, the first part of the chip 2000 is accommodated in the positioning groove 201, and the second part of the chip 2000 is connected to and squeezes the elastic conductive member 302.

[0101] Optionally, as shown in Figures 4 and 5, the first end of the chip 2000 is provided with a first card slot 2001, and the second end of the chip 2000 is provided with a second card slot 2002, the second card slot 2002 is used to be clamped with the first stopping end 211 and the second stopping end 311, and the first card slot 2001 is used to be clamped with the limit member 400.

[0102] Specifically, when the first base 21 is in the first mating position and the chip 2000 is mounted on the base, the first latching end 211 protrudes from the second receiving groove 13 based on the telescopic member 40 and extends into the positioning groove 201, for engaging with the second latching groove 2002 of the chip 2000, while the second latching end 311 is received in the first receiving groove 12. When the first base 21 is in the first avoiding position and the chip 2000 is removed from the base, the second latching end 311 rotates out of the first receiving groove 12 and extends into the positioning groove 201, for engaging with the second latching groove 2002 of the chip 2000, while the first latching end 211 is received in the second receiving groove 13.

[0103] In these optional embodiments, such a configuration can achieve the chip 2000 stopping at a predetermined position, thereby reducing the defect of undesirable movement. In addition, the second latching end 311 can be received in the first receiving groove 12, and the first latching end 211 can be received in the second receiving groove 13, thereby reducing the overall space occupied by the locking mechanism 100, reducing the risk of accidental contact with the chip 2000, and protecting the first latching end 211 and the second latching end 311, thereby extending the service life of the locking mechanism 100.

[0104] In some optional embodiments, as shown in Figures 2 and 3, the stopper 400 is connected to the base 200 and extends along the arrangement direction x toward the positioning groove 201, and the stopper 400 partially covers the positioning groove 201. This arrangement simplifies the installation of the stopper 400 and the chip 2000 and reduces the overall manufacturing cost of the electronic device 1000.

[0105] In some optional embodiments, as shown in Figures 1 and 2, the base 200 is provided with a guide groove 202 along the arrangement direction x, and the guide groove 202 is connected to the positioning groove 201. The locking mechanism 100 also includes a keycap 50 and a connector 60. One end of the connector 60 is disposed in the guide groove 202 and slides along the guide groove 202. The other end of the connector 60 passes through the first base 21 and is connected to the keycap 50.

[0106] Optionally, the connecting member 60 is a bolt, one end of which is disposed in the guide groove 202 and slides along the guide groove 202, and the other end of the bolt is threadedly connected to the first base 21 and the keycap 50. This arrangement not only increases the connection stability between the first base 21 and the keycap 50, but also guides the movement of the first base 21 and the keycap 50.

[0107] In some optional embodiments, as shown in FIG1 , the first retaining end 211 includes an inclined surface 2111. This facilitates mounting the chip 2000 on the electronic device 1000 for testing. Optionally, the inclined surface 2111 is disposed at an acute angle to the arrangement direction x. In this embodiment of the present application, the inclined surface 2111 being disposed at an acute angle to the arrangement direction x means that the inclined surface 2111 is disposed at an acute angle to the direction from the first retaining end 211 toward the telescopic member 40.

[0108] In other embodiments of the present application, a detection device is provided, which includes a base, a locking mechanism, an elastic member and a sensor. The locking mechanism is arranged on the base. The elastic member is arranged on the base, wherein, when the locking mechanism is in a first locking state, the first locking end is used to cooperate with the member to be detected, and when the member to be detected is configured to be installed on the base, the member to be detected squeezes the elastic member, and the member to be detected is electrically connected to the sensor through the elastic member; when the locking mechanism is in a second locking state, the second locking end is used to cooperate with the member to be detected, and when the member to be detected is configured to be disassembled from the base, the second locking end is used to limit the movement of the member to be detected in a direction away from the elastic member, the member to be detected is at least partially separated from the elastic member, and the member to be detected is not conductive to the sensor.
