It should be noted that the embodiments of the present disclosure and the features in the embodiments can be combined with each other without conflict.

[0038] In the following description, many specific details are set forth to facilitate a full understanding of the present disclosure, but the present disclosure may also be implemented in other ways different from those described herein; it is obvious that the embodiments in the specification are only part of the embodiments of the present disclosure, rather than all of the embodiments.

[0039] Reference Figures 1 to 14 As shown, some embodiments of the present disclosure provide a lock assembly, including a lock shell 11 and a lock cover plate 12 covering the lock shell 11, the bottom of the lock shell 11 is recessed toward the direction close to the lock cover plate 12 to form an installation groove 10, and a lock catch 2 is provided on the installation groove 10, and the lock catch 2 is used to lock the lock catch assembly fixed at the safety seat interface 200 in the installation groove 10 to achieve locking cooperation between the lock assembly and the lock catch assembly, and an installation area for fixing the vehicle-mounted component 300 is formed on the lock cover plate 12 to fix the vehicle-mounted component 300 to connect the vehicle-mounted component 300 to the lock assembly.

[0040] In the current vehicle cabin environment, in order to facilitate the installation of child safety seats, a safety seat interface 200, also known as a Latch (Lower Anchors and Tethers for Children, referred to as Latch) interface, is configured on the rear vehicle seat 100. The Latch interface is specifically located on the back of the vehicle seat 100. In order to ensure the stability of the child safety seat, the upper load limit of this interface is relatively high. Therefore, installing a child safety seat on this interface is highly safe.

[0041] The lock assembly provided by the present disclosure has a bottom of the lock housing 11 that is recessed toward the lock cover plate 12 to form a mounting groove 10 for accommodating the lock assembly. The mounting groove 10 can ensure that the lock assembly is more adaptably fixedly connected to the lock assembly, and the two opposite side walls of the mounting groove 10 are provided with lock members 2. By providing the lock members 2, the flexibility of locking and unlocking between the lock assembly and the lock assembly can be ensured. The lock cover plate 12 is formed with a mounting area for fixing the vehicle-mounted component 300, so that the lock cover plate 12 of the lock assembly can be used as a loading platform alone. As a loading platform, it can also ensure safety and achieve rapid reuse, thereby improving the practicality of the lock assembly. For example, objects such as drones and loading platforms can be placed on the lock cover plate 12, or the lock cover plate 12 can be fixed to the bottom of the vehicle-mounted component 300. When it is necessary to fix the vehicle-mounted component 300 in the vehicle cabin, the lock assembly at the safety seat interface 200 is stably locked in the installation groove 10 through the lock pieces 2 on both sides, so as to realize the locking cooperation between the lock head assembly and the lock assembly. The lock pieces 2 on both sides can ensure the locking reliability of the lock assembly in the installation groove 10; when it is not necessary to fix the vehicle-mounted component 300, the lock assembly is directly unlocked from the installation groove 10 through the lock piece 2, so as to ensure the flexible disassembly of the lock head assembly and the vehicle-mounted component 300. After the vehicle seat 100 is folded and laid flat, the vehicle-mounted component 300 is fixed at the safety seat interface 200 through the locking cooperation between the lock head assembly and the lock buckle assembly, which can effectively improve the fixing stability of the vehicle-mounted component 300, so that the vehicle-mounted component 300 can still be stably fixed on the vehicle seat 100 when the vehicle is on a bumpy road or in a collision condition, avoiding the vehicle-mounted component 300 from being scattered or causing a collision due to unreliable fixation, thereby endangering the life safety of the passengers, providing a safer riding environment for the passengers, and reducing the risk of damage to the vehicle-mounted component 300, improving the security of the fixation of the vehicle-mounted component 300 and the practicality of the safety seat interface 200, and can expand the functionality and application scenarios of the safety seat interface 200, and fixing the vehicle-mounted component 300 at the safety seat interface 200 through the lock head assembly can expand the storage space inside the vehicle and improve the space utilization rate of the cabin.

[0042] In some embodiments, reference Fig.11 and Fig.14 As shown, the lock assembly includes a lock body 3, and a snap-fit ​​groove 4 is formed on the side of the lock body 3 to snap-fit ​​with the lock member 2 to achieve locking cooperation between the lock head assembly and the lock assembly.

The safety seat interface 200 includes a latch port 201 and an interface frame 202 disposed in the latch port 201. The interface frame 202 is connected and fixed to the seat frame of the vehicle seat 100, so the interface frame 202 itself has a high structural strength and a high load-bearing upper limit.

[0044] In addition, a lock hook 5 for connecting to the safety seat interface 200 is provided on the lock body 3 . The lock hook 5 is used to be hooked and matched with the interface frame 202 , so as to fix the lock body 3 on the safety seat interface 200 .

[0045] In some embodiments, the mounting housing 30 includes a buckle lower cover 302 and a buckle upper cover 301 covering the buckle lower cover 302. The buckle lower cover 302 is used to be placed at the safety seat interface 200, and the buckle lower cover 302 is formed with a first avoidance opening that allows the interface frame 202 to be exposed. An installation space is formed between the buckle upper cover 301 and the buckle lower cover 302. The lock hook 5 is arranged in the installation space and is hooked and matched with the interface frame 202 through the first avoidance opening to fix the buckle body 3 on the safety seat interface 200.

[0046] Furthermore, the mounting housing 30 further includes a lock bracket 303, the size of which can be adapted to the size of the lock lower cover 302, and the lock bracket 303 is disposed in the mounting space and connected to the lock lower cover 302, and the connection method can be bonding, welding or screwing. The lock bracket 303 is formed with a second avoidance opening corresponding to the first avoidance opening for the interface frame 202 to be exposed, one end of the lock hook 5 is fixed to the lock bracket 303, and the other end of the lock hook 5 extends into the second avoidance opening and hooks the interface frame 202.

[0047] In some embodiments, an operation port communicating with the installation space is formed on the top of the latch cover 301, and the operation port is detachably covered with an inner cover 304. The inner cover 304 and the latch cover 301 can be fixed by snap connection, for example, a protrusion is provided on the inner cover 304, and a connecting groove is provided on the edge of the operation port, and the protrusion and the connecting groove cooperate with each other to fix the inner cover 304 on the latch cover 301, so as to achieve the blocking of the operation port, prevent dust or other debris from entering the operation port and the latch port 201, causing damage to the internal structure thereof, and make the appearance of the latch body 3 more complete and beautiful.

[0048] Furthermore, the lock upper cover 301 includes a top cover and a side plate connected to the periphery of the top cover, the bottom periphery of the side plate is connected to the lock lower cover 302, and the clamping groove 4 is provided on the side plate. In actual application, the connection between the side plate and the lock lower cover 302 can be screwed, clamped, or bonded. Specifically, refer to Figure 8 As shown, the side plate and the lock lower cover 302 are fixed by snapping, a plugging protrusion is formed at the bottom periphery of the side plate, and a slot that is plugged with the plugging protrusion is formed at the periphery of the lock lower cover 302 to fix the side plate and the lock lower cover 302. The snap groove 4 is a snap groove formed on two opposite side walls of the side plate, and the snap groove is connected to the lock head assembly to fix the vehicle-mounted component 300 on the safety seat interface 200.

[0049] Reference Fig. 9 and Fig.10 As shown, specifically, the lock hook member 5 includes a lock hook bottom plate 51, a torsion spring 53 and a lock hook upper plate 52. The lock hook bottom plate 51 is fixed on the mounting housing 30. The lock hook upper plate 52 is hingedly matched with the lock hook bottom plate 51 through the torsion spring 53. A pressing portion is formed at one end of the lock hook upper plate 52, and a lock hook for hanging and matching with the interface frame 202 is formed at the other end of the lock hook upper plate 52. When the pressing portion on the lock hook upper plate 52 is pressed, the lock hook releases the hanging of the interface frame 202 and tilts upward, so that the lock buckle body 3 is disengaged from the safety seat interface 200.

[0050] Reference Fig.13 and Fig.14 As shown, specifically, the lock component 2 includes an elastic portion 21 and a snap-on protrusion 22. The elastic portion 21 is located in the lock housing 11. The elastic portion 21 can be a spring or other structure with elastic force. One end of the elastic portion 21 is fixed to the side wall of the lock housing 11, and the other end of the elastic portion 21 is fixed to the snap-on protrusion 22. The snap-on protrusion 22 is configured to extend into the mounting groove 10 under the elastic force of the elastic portion 21 to achieve locking cooperation with the lock assembly.

[0051] Furthermore, the lock housing 11 is a cover structure, and the lock housing 11 and the lock cover plate 12 jointly form a accommodating cavity 13. The locking member 2 is located on two opposite side walls of the mounting groove 10. The accommodating cavity 13 and the corresponding portion of the locking member 2 are connected to the mounting groove 10 so that the engaging protrusion 22 can move relative to the mounting groove 10 and the accommodating cavity 13. Specifically, the locking member 2 can extend from the accommodating cavity 13 to the mounting groove 10 or retract from the mounting groove 10 to the accommodating cavity 13.

[0052] Reference Fig.13As shown, the end of the snap-fit ​​protrusion 22 away from the elastic part 21 is formed into an inclined surface, and the side of the lock body 3 abuts against the inclined surface and compresses the elastic part 21, so that the snap-fit ​​protrusion 22 extends from the accommodating cavity 13 into the installation groove 10 and snaps into the snap-fit ​​groove 4. Specifically, when the snap-fitting protrusion 22 is not engaged with the snap-fitting groove 4, it extends into the mounting groove 10 under the elastic force of the elastic portion 21. When the lock head assembly and the lock buckle assembly are locked and engaged, in the process of placing the lock buckle upper cover 301 in the mounting groove 10, the side portion of the side plate portion cooperates with the inclined surface of the end portion of the snap-fitting protrusion 22. As the lock buckle upper cover 301 is continuously pressed downward, the snap-fitting protrusion 22 gradually compresses the elastic portion 21 in the direction away from the mounting groove 10 to allow the lock buckle upper cover 301 to be completely accommodated in the mounting groove 10. When the center of the snap-fitting groove 4 is flush with the center of the snap-fitting protrusion 22, the snap-fitting protrusion 22 extends toward the mounting groove 10 under the elastic force of the elastic portion 21, and extends into the snap-fitting groove 4, completing the locking engagement between the lock head assembly and the lock buckle assembly.

[0053] In some embodiments, reference Fig.11 , Fig.12 and Fig.14 As shown, the lock assembly also includes a driving rod 6, which is movably arranged in the accommodating cavity 13. A trigger end 60 is formed at one end of the driving rod 6. A matching portion that slidably cooperates with the snap-fitting protrusion 22 is provided on the driving rod 6. When the trigger end 60 on the driving rod 6 is touched, the matching portion is linked by the trigger end 60 to drive the snap-fitting protrusion 22 to disengage from the snap-fitting groove 4 and retract from the mounting groove 10 into the accommodating cavity 13, thereby unlocking the lock member 2 and the snap-fitting groove 4, and unlocking the lock assembly and the lock assembly.

[0054] Furthermore, two locking members 2 are respectively arranged on the two opposite side walls of the mounting groove 10, and the number of the locking members 2 is four. The driving rod 6 includes two driving arms 61, and one end of the two driving arms 61 is connected to form a trigger end 60. The other ends of the two driving arms 61 are respectively extended toward the corresponding locking members 2, and the end portions of the other ends are respectively provided with two matching parts, and the number and setting positions of the matching parts are adapted to the locking members 2.

[0055] Specifically, a button 14 is provided on the side wall of the lock housing 11, and the button 14 can be locked on the side wall of the lock housing 11, and the button 14 is fixed in linkage with the trigger end 60. One driving arm 61 is slidably matched with the clamping protrusion 22 on one side, and the other driving arm 61 is slidably matched with the clamping protrusion 22 on the opposite side. A convex column 221 is convexly provided on the side of the clamping protrusion 22 away from the installation groove 10, and the matching part is an inclined groove 611 formed on the side wall of the driving arm 61, and the inclined groove 611 is slidably matched with the convex column 221. The convex column 221 is configured to move relatively in the inclined groove 611 with the movement of the driving arm 61, so as to drive the clamping protrusion 22 to retract into the accommodating cavity 13, that is, under the cooperation of the convex column 221 and the inclined groove 611, the clamping protrusion 22 is retracted into the accommodating cavity 13, so as to achieve unlocking between the clamping groove 4 and the lock member 2. When it is necessary to unlock the lock head assembly and the lock catch assembly, it is only necessary to press the button 14, and the button 14 is linked with the trigger end 60 to drive the two driving arms 61 to move in the direction away from the button 14, so that the boss 221 moves synchronously with the inclined groove 611 as the driving arm 61 moves. At this time, the engaging protrusion 22 will overcome the elastic force of the elastic part 21, retract from the engaging groove 4 and move along the mounting groove 10 and the accommodating cavity 13 in the direction away from the engaging groove 4 to achieve the disengagement between the engaging groove 4 and the lock catch 2, and then the lock catch upper cover 301 is removed from the mounting groove 10, thereby achieving the unlocking between the lock catch assembly and the lock head assembly.
