[0058] Some other embodiments of the present disclosure further provide a locking device, referring to Figures 8 to 14 As shown, the locking device includes a lock assembly and a lock assembly as in any of the above embodiments, the lock assembly includes a lock body 2, the lock body 2 is provided with a lock portion 21, the lock portion 21 is used to connect with the lock groove 12 of the lock assembly to achieve locking cooperation between the lock assembly and the lock assembly, wherein the lock assembly is used to connect with the vehicle-borne component 300, by folding the vehicle seat 100 and laying it down, so that the safety seat interface 200 on the back of the vehicle seat 100 is placed on a plane, and the lock assembly is connected to the lock assembly fixed on the safety seat interface 200 to form a locking device for locking the vehicle-borne component 300 on the safety seat interface 200, thereby limiting the shaking or displacement of the vehicle-borne component 300 and ensuring the fixed safety and stability of the vehicle-borne component 300.

[0059] In some embodiments, reference Figures 8 to 10 As shown, the lock body 2 includes a lock housing 20 and a lock cover plate 22 covering the lock housing 20 , the lock catch portion 21 is disposed on the lock housing 20 , and a mounting area for fixing the vehicle-mounted component 300 is formed on the lock cover plate 22 .

[0060] It should be noted that the lock hook bottom plate 111 and the lock buckle bracket 103 are fixedly connected, and the lock hook upper plate 112 and the interface frame 202 are hung and fixed, so that the fixation between the lock hook 11 and the interface frame 202 is relatively stable, and it can prevent the vehicle-mounted component 300 from being displaced to break the connection between the lock buckle assembly and the safety seat interface 200 when the vehicle brakes suddenly or collides. On this basis, the locking device of the lock head assembly and the lock buckle assembly has certain versatility and modularity. The lock head assembly can not only be used to fix the vehicle-mounted component 300, but also the lock head cover plate 22 of the lock head assembly can be used as a loading platform alone. As a loading platform, it can also ensure safety and achieve rapid reuse, which improves the practicality of the lock head assembly. For example, objects such as drones and loading platforms can be placed on the lock head cover plate 22, or the lock head cover plate 22 can be fixed to the bottom of the vehicle-mounted component 300.

[0061] In some embodiments, reference Fig.11 and Fig.12As shown, the bottom of the lock housing 20 is recessed toward the direction close to the lock cover plate 22 to form an installation groove 24 to install and accommodate the lock assembly. In the actual installation process, the fixing method between the lock housing 20 and the lock assembly can be set to other structures according to the actual installation requirements, as long as the installation between the lock assembly and the lock assembly can be achieved. The lock portion 21 is a movable member 23 arranged on two opposite side walls of the installation groove 24. The movable member 23 is telescopically arranged in the installation groove 24 to achieve a snap fit with the lock groove 12 (i.e., the snap groove) provided on the lock assembly, so as to achieve a locking fit between the lock assembly and the lock assembly.

[0062] Reference Fig.12 and Fig.13 As shown, specifically, the movable member 23 includes an elastic portion 231 and a snap-on protrusion 232. The elastic portion 231 is located in the lock housing 20. The elastic portion 231 can be a spring or other elastic structure. One end of the elastic portion 231 is fixed to the side wall of the lock housing 20, and the other end of the elastic portion 231 is fixed to the snap-on protrusion 232. The snap-on protrusion 232 is configured to extend into the mounting groove 24 under the elastic force of the elastic portion 231 to achieve locking cooperation with the lock buckle groove 12. Fig.13 As shown, the end of the snap-fitting protrusion 232 away from the elastic portion 231 is formed as an inclined surface. When the snap-fitting protrusion 232 is not matched with the lock buckle groove 12, it extends into the installation groove 24 under the elastic force of the elastic portion 231. When the lock head assembly and the lock buckle assembly are locked and matched, the lock buckle upper cover 101 is accommodated in the installation groove 24. The side portion of the side plate portion 101c cooperates with the inclined surface of the end of the snap-fitting protrusion 232. As the lock buckle upper cover 101 is continuously pressed downward, the snap-fitting protrusion 232 gradually compresses the elastic portion 231 in the direction away from the installation groove 24 to allow the lock buckle upper cover 101 to be completely accommodated in the installation groove 24. When the center of the snap-fitting groove is flush with the center of the snap-fitting protrusion 232, the snap-fitting protrusion 232 extends in the direction close to the installation groove under the elastic force of the elastic portion 231, and extends into the snap-fitting groove, completing the locking cooperation between the lock head assembly and the lock buckle assembly.

[0063] Furthermore, the lock housing 20 is a cover structure, and the lock housing 20 and the lock cover plate 22 together form a receiving cavity 27, and the elastic portion 231 is received in the receiving cavity 27. The portion corresponding to the movable member 23 on the receiving cavity 27 is connected to the mounting groove 24, so that the engaging protrusion 232 can move relative to the mounting groove 24 and the receiving cavity 27.

[0064] The lock assembly also includes a driving rod 25, which is movably disposed in the accommodating cavity 27. A trigger end 251 is formed at one end of the driving rod 25. A matching portion that slidably matches with the clamping protrusion 232 is provided on the driving rod 25 to drive the clamping protrusion 232 to retract from the mounting groove 24 into the accommodating cavity 27. When the trigger end 251 on the driving rod 25 is triggered, the matching portion is linked with the trigger end 251, and the clamping protrusion 232 is driven to disengage from the clamping groove and retract into the accommodating cavity 27, thereby realizing the unlocking between the lock assembly and the lock buckle assembly.

[0065] Reference Figures 10 to 12 As shown, specifically, a button 26 is provided on the side wall of the lock housing 20, and the button 26 is movably located on the side wall of the lock housing 20, and the button 26 is linked and fixed with the trigger end 251. The driving rod 25 has two rod bodies, one rod body is slidably matched with the clamping protrusion 232 on one side, and the other rod body is slidably matched with the clamping protrusion 232 on the opposite side. A boss 232a is convexly provided on the side of the end of the snap-fitting protrusion 232 facing away from the installation groove 24, and the matching part is an inclined groove 252 formed on the side wall of the driving rod 25. The inclined groove 252 is slidably matched with the boss 232a, and the boss 232a is configured to be relatively movable in the inclined groove 252 with the movement of the driving rod 25, so as to drive the snap-fitting protrusion 232 to retract into the accommodating chamber 27, that is, under the cooperation of the boss 232a and the inclined groove 252, the snap-fitting protrusion 232 is retracted into the accommodating chamber 27, so as to realize the unlocking between the locking portion 21 and the locking groove 12. When it is necessary to unlock the lock head assembly and the lock catch assembly, it is only necessary to press the button 26, and the button 26 is linked with the trigger end 251 to drive the two rod bodies of the driving rod 25 to move in the direction away from the button 26, so that the boss 232a moves synchronously with the inclined groove 252 as the driving rod 25 moves. At this time, the engaging protrusion 232 will overcome the elastic force of the elastic part 231, retract from the engaging groove and move along the mounting groove 24 and the accommodating cavity 27 in the direction away from the engaging groove to achieve the disengagement between the lock catch groove 12 and the lock catch part 21, and then the lock catch upper cover 101 is removed from the mounting groove 24, thereby achieving the unlocking between the lock catch assembly and the lock head assembly.

[0066] Still other embodiments of the present disclosure provide a vehicle, comprising a vehicle seat 100 and a locking assembly as in any of the above embodiments, wherein a safety seat interface 200 is provided on the back of the vehicle seat 100, and the technical features of the locking assembly used in the vehicle can be found in the locking assembly in the above embodiments, which will not be described in detail here.
