[0067] like Figures 1 to 8 As shown, a locking mechanism is proposed according to a first aspect of the present application, comprising: a power unit 110, the power unit 110 including a drive member 111, a connecting rod 112 and a transmission member 113, one end of the drive member 111 being connected to one end of the connecting rod 112, and the other end of the connecting rod 112 being connected to the transmission member 113; a disconnection unit 120, the disconnection unit 120 including a rotating shaft 121 and a locking member 122, the connecting rod 112 being used to rotate about the rotating shaft 121 as a fulcrum, and the locking member 122 being used to lock or unlock the rotating shaft 121. When the rotating shaft 121 is unlocked, the rotating shaft 121 loses its fulcrum function, the drive member 111 releases the constraint on the transmission member 113, and the transmission member 113 can move freely. For example, the connecting rod 112 can rotate about the connection point between the connecting rod 112 and the drive member 111 as a fulcrum; and an auxiliary door opening unit 130, the auxiliary door opening unit 130 being used to assist in opening the door 220.

[0068] The locking mechanism provided by the embodiment of the present application comprises a power unit 110, a disconnecting unit 120 and an auxiliary door opening unit 130. The power unit 110 can comprise a driving member 111, a connecting rod 112 and a transmission member 113. When the door body 220 of the shielding cabin is opened by using the starting locking structure, the driving member 111 of the power unit 110 can be started, the driving member 111 drives the transmission member 113 to move through the connecting rod 112, and the transmission member 113 can drive the door body 220 to separate from the cabin body 210, so as to realize the opening of the door body 220 of the shielding cabin. When the power unit 110 fails, the disconnecting unit 120 can be started, the locking member 122 is controlled to unlock the rotating shaft 121, the rotating shaft 121 loses the effect of fulcrum, the connecting rod 112 can rotate at the connecting position of the connecting rod 112 and the driving member 111, the power unit 110 is disconnected, and the door body 220 can be opened by manpower. If the opening resistance of the door body 220 is large, the auxiliary door opening unit 130 can be started to assist in opening the door body 220, so as to ensure the smooth opening of the door body. Similarly, in an emergency, the door body 220 can also be opened by using the auxiliary door opening unit 130. If the door body 220 cannot be opened due to the resistance of the power unit 110 during the emergency opening of the door body 220, the power unit 110 can be unlocked by using the disconnecting unit 120, and then the door body 220 can be opened by using the auxiliary door opening unit 130, so as to ensure the smooth opening of the door body and make the opening of the door body 220 more convenient.

[0069] In some examples, the power unit 110 can comprise a pneumatic cylinder or an electric push rod, and of course can also comprise other driving structures, as long as the connecting rod 112 can be driven to rotate around the rotating shaft 121.

[0070] As shown in FIGS. 1, 2 and 3, the power unit 110 can comprise a driving member 111, a connecting rod 112 and a transmission member 113. Figure 1 and Figure 4 In a feasible implementation, the power unit 110 further comprises a guide bearing 114, the guide bearing 114 is arranged on the door body 220, the transmission member 113 passes through the guide bearing 114, and the guide bearing 114 guides and limits the transmission member 113; a guide member 115, the guide member 115 is connected to the cabin body 210, and an inclined guide groove 117 is formed in the guide member 115; and an unlocking member 116, the unlocking member 116 is connected to the transmission member 113 and movably arranged on the guide groove 117. When the unlocking member 116 is at the root of the guide groove 117, the door body 220 is attached to the cabin body 210, and when the unlocking member 116 is at the top of the guide groove 117, the door body 220 separates from the cabin body 210.

[0071] In the technical solution, the structural composition of the power unit 110 is further provided, and the power unit 110 can further include a guide bearing 114, a guide piece 115 and a locking piece 122. Based on this, the guide bearing 114 is arranged, and the connecting rod 112 drives the movement of the transmission piece 113. The connecting rod 112 can drive the transmission piece 113 to move relative to the guide bearing 114. The transmission piece 113 can drive the unlocking piece 116 to move in the guide groove 117 of the guide piece 115. The unlocking piece 116 moves in the guide groove 117, which can drive the door body 220 to approach or move away from the cabin body 210, so as to automatically open the door body 220.

[0072] The guide bearing 114 is at least two, which are divided into two groups and arranged at the ends of the transmission piece 113. In this way, the guide bearing 114 can better guide the transmission piece 113. Figure 1 As shown in the figure, the guide bearing 114 can be four, and the four guide bearings 114 are divided into two groups and arranged at the two ends of the transmission piece 113.

[0073] Specifically, the guide groove 117 can be arranged obliquely relative to the side wall of the cabin body 210. When the unlocking piece 116 is at the root of the guide groove 117, the door body 220 is attached to the cabin body 210. When the unlocking piece 116 is moved to the top of the guide groove 117 under the action of the transmission piece 113, the door body 220 can be separated from the cabin body 210.

[0074] It can be understood that, in order to facilitate the assembly of the unlocking piece 116 and the movement of the unlocking piece 116 in the guide groove 117, the opening direction of the guide groove 117 can be arranged towards the top of the cabin body 210.

[0075] As shown in the figure, Figure 3 and Figure 6As shown, in an embodiment, the locking member 122 comprises a frame 1221 connected to the door body 220, the connecting rod 112 passes through the frame 1221, the frame 1221 is arranged with a locking groove in the height direction, the rotating shaft 121 on the connecting rod 112 is located in the locking groove, the connecting rod 112 is movably or rotatably connected to the frame 1221 through the rotating shaft 121; a fixed shaft 1222 and a base 1223, the base 1223 is slidingly arranged in the locking groove, the lower end of the fixed shaft 1222 is connected to the base 1223, the fixed shaft 1222 is connected to the rotating shaft 121 through the base 1223; a reset member 1225 and a limiting nut 1228, the limiting nut 1228 is connected to the upper end of the fixed shaft 1222, the reset member 1225 is sleeved on the fixed shaft 1222, the lower end of the reset member 1225 abuts against the upper end of the frame 1221, and the upper end abuts against the limiting nut 1228; an unlocking switch 1224, the unlocking switch 1224 is hingedly connected to the frame 1221, in the case that the rotating shaft 121 is locked, the unlocking switch 1224 abuts against the upper end of the fixed shaft 1222, the unlocking switch 1224 locks the rotating shaft 121 through the fixed shaft 1222 and the base 1223, preventing the rotating shaft 121 from moving up and down; in the case that the unlocking switch 1224 is rotated relative to the frame 1221 and separated from the upper end of the fixed shaft 1222, the reset member 1225 applies an elastic force to the fixed shaft 1222 through the limiting nut 1228, and the rotating shaft 121 is unlocked.

[0076] In the technical scheme, the structure of the locking member 122 is further provided, the locking member 122 can comprise the frame 1221, the fixed shaft 1222, the base 1223 and the unlocking switch 1224, the frame 1221 provides a mounting position for the fixed shaft 1222 and the base 1223, and can also limit the connecting rod 112. When the unlocking switch 1224 abuts against the upper end of the fixed shaft 1222, the unlocking switch 1224 overcomes the elastic force of the reset member 1225 and locks the rotating shaft 121 through the fixed shaft 1222 and the base 1223, preventing the rotating shaft 121 from moving up and down, so that the connecting rod 112 can rotate around the rotating shaft 121 as a fulcrum. When the power unit 110 fails or needs to be disconnected, the unlocking switch 1224 can be rotated to separate the unlocking switch 1224 from the upper end of the fixed shaft 1222, the unlocking switch 1224 loses the limiting effect on the fixed shaft 1222, the elastic force of the reset member 1225 can act on the limiting nut 1228, and then drive the fixed shaft 1222 to move away from the rotating shaft 121, the connecting rod 112 loses the fulcrum effect, so that the power unit 110 is in a disconnected state, and the use of the locking mechanism is safer.

[0077] As Figure 3 and Figure 6As shown, in one feasible embodiment, the locking member 122 further includes: a sensor 1226 connected to the frame 1221; and a sensor detection piece 1227 connected to the unlocking switch 1224. When the unlocking switch 1224 locks the rotating shaft 121, the sensor 1226 can detect the sensor detection piece 1227.

[0078] In this technical solution, the structure of the locking member 122 is further provided. The locking member 122 may also include a sensor 1226 and a sensor detection piece 1227. Based on this, the position of the unlocking switch 1224 can be detected by setting the sensor 1226 and the sensor detection piece 1227, ensuring that the unlocking switch 1224 is in the locked position when the shielded cabin is in normal use.

[0079] In some examples, the locking mechanism may also include a processor and an alarm. The processor is connected to the sensor 1226. If the sensor 1226 does not detect the sensor detection piece 1227, it indicates that the unlocking switch 1224 has not been reset, and the processor can control the alarm to sound an alarm.

[0080] like Figure 2 As shown, in one feasible embodiment, the auxiliary door opening unit 130 includes: an energy storage component 131, which stores energy and is connected to the door body 220; a firing lever 132, which is connected to the energy storage component 131; and an unlocking part 134, which releases the energy of the energy storage component 131 so that the firing lever 132 abuts against the cabin body 210.

[0081] In this technical solution, the structure of the auxiliary door opening unit 130 is further provided. The auxiliary door opening unit 130 may include an energy storage element 131, a firing lever 132 and an unlocking part 134. In the natural state, the unlocking part 134 locks the energy storage element 131, the energy storage element 131 is in the energy storage state, the firing lever 132 is not in contact with the cabin 210, and the door 220 can be opened by the power unit 110. When the power unit 110 malfunctions, it can be disconnected by disconnecting unit 120. Then, the energy storage unit 131 can be unlocked by unlocking unit 134. The energy storage unit 131 releases energy, which can drive the firing rod 132 to move. The firing rod 132 abuts against the cabin 210, which can move the door 220 away from the cabin 210, and the door 220 can be opened. This ensures the smooth opening of the door 220 of the shielded cabin. Even if the power unit 110 is in a malfunctioning state, the door 220 can still be opened smoothly, making the use of the shielded cabin more convenient and safe.

[0082] like Figure 2As shown, in one feasible embodiment, the energy storage component 131 includes: a frame 1311 connected to the door 220, with the transmission component 113 passing through the frame 1311; a limiting component 1312 and a limiting pin 1313, with the limiting pin 1313 connected to the firing lever 132 and the limiting component 1312 rotatably connected to the frame 1311; and a spring 1314 sleeved on the firing lever 132, with one end of the spring 1314 abutting against the frame 1311 and the other end abutting against the limiting pin 1313.

[0083] like Figure 2 , Figure 7 and Figure 8 As shown, in one feasible embodiment, the unlocking part 134 includes: a retaining member 1341, which is disposed inside the frame 1311 and hinged at both ends to the frame 1311, and is arranged on one side of the limiting member 1312; and an unlocking screw 1342, which is disposed on the frame 1311 and connected to the retaining member 1341, for driving the retaining member 1341 to rotate relative to the frame 1311; wherein, when the retaining member 1341 rotates relative to the frame 1311 to avoid the limiting member 1312, the spring 1314 releases energy to push the limiting member 1312 to rotate relative to the frame 1311 and trigger the firing rod 132.

[0084] In this technical solution, the structure of the energy storage component 131 is further provided. The energy storage component 131 may include a frame 1311, a limiting component 1312, a limiting pin 1313, and a spring 1314. The frame 1311 provides an installation position for the energy storage component 131, and facilitates the formation of the limiting component 1312 and the setting and positioning of the spring 1314. The spring 1314 is sleeved on the firing rod 132. In the natural state, the limiting pin 1313 on the firing rod 132 abuts against the limiting component 1312, while the spring 1314 is in a compressed state. In this case, the energy storage component 131 is in an energy storage state.

[0085] When the door body needs to be opened by the auxiliary door opening unit 130, the unlocking screw 1342 arranged on the frame 1311 can be screwed, the retaining member 1341 is driven by the unlocking screw 1342 to rotate away from the limiting member 1312, the retaining member 1341 avoids the limiting member 1312, in this case, the elastic force of the spring 1314 acts on the limiting member 1312, the limiting member 1312 rotates relative to the frame 1311 under the elastic force, the limiting member 1312 loses the limiting effect on the spring 1314, the firing rod is fired under the elastic force of the spring 1314, so that the firing rod 132 abuts on the cabin body 210, drives the door body 220 away from the cabin body 210, and the opening of the shielding cabin door body 220 is realized, especially in the case of failure of the power unit 110, the opening of the door body 220 can also be realized, so that the use of the shielding cabin is safer and more convenient.

[0086] It can be understood that if the door body 220 is not directly opened by the auxiliary door opening unit 130, the power unit 110 can be disconnected by the disconnecting unit 120, and the opening of the door body 220 can be realized by the excitation of the spring 1314 of the auxiliary door opening unit 130.

[0087] As shown in Figure 2 , Figure 7 and Figure 8 , in a possible implementation, the auxiliary door opening unit 130 further comprises a reset unit 133, the reset unit 133 is used for resetting the spring 1314, and the reset unit 133 comprises a limiting frame 1331, one end of the firing rod 132 extends through the frame 1311 and is arranged in the limiting frame 1331, and a pull pin 1332 connected to the firing rod 132 through the limiting frame 1331.
