[0047] In an embodiment of the present application, the bottom frame mechanism 5 is connected with the linkage assembly 21 and the support assembly 23 of the multi-point linkage mechanism 2, and is used for supporting the transport damping locking device 1. The connecting rod 213 is connected with the support assembly 23 and the locking mechanism 24 through a bearing connecting assembly or a sliding connecting assembly.

[0048] In some embodiments of the present application, the multi-point linkage mechanism 2 further comprises a reset device 22, which comprises a plurality of elastic components with elastic deformation arranged on the connecting rod 213 and the swing rod mechanism 214.

[0058] In an embodiment of the present application, the unlocking position sensor 28 and the locking position sensor 29 are respectively installed at the unlocking position and the locking position of the corresponding locking component 241 of the locking mechanism 24, so as to accurately position the position of the locking component 241 of the locking mechanism 24 of the multi-point linkage mechanism 2 when the locking mechanism is locked and unlocked.

[0059] In an embodiment of the present application, the number of the unlocking position sensor 28 and the locking position sensor 29 for positioning the unlocking position or the locking position of the locking mechanism 24 is not less than one. The positioning device 24 is arranged on both sides of the connecting rod 213, which is used to position the locking position in the locked state and the unlocking position in the unlocked state of the locking component 24 of the multi-point locking structure 2.

[0060] Optionally, the unlocking position sensor 28 and the locking position sensor 29 of each positionable locking component 241 of the multi-point linkage mechanism 2 are uniformly or non-uniformly distributed on both sides of the connecting rod 213 at a certain interval, and at least two sensors are used to collect the current position information at each unlocking position and locking position, and then the unlocking position information and the locking position information are judged, and the sensors arranged at the unlocking position 28 and the locking position 29 are all redundantly arranged, so that the system is not damaged by the failure of a single sensor, and the locking state detection of the transportation shock-absorbing locking device is more reliable.
