For those of ordinary skill in the art, the specific meaning of the terms mentioned above in the present invention should be construed in specific situations.

[0023] As shown in FIG. 1, a safety seat provided by an embodiment of the present invention includes: a base 100, a seat back 200, a locking member 300, a linkage member 400 and a lock driving member 500. The seat back 200 is hinged to the base 100, and the seat back 200 is provided with lock holes 201 adapted to the locking member 300. The locking member 300 is movably connected to the base 100, the lock driving member 500 is mounted on the base 100, and the lock driving member 500 is in transmission connection with the locking member 300 via the linkage member 400.

[0024] The lock driving member 500 drives the locking member 300 via the transmission of the linkage member 400, and thus a reciprocating switch between a locked state and an unlocked state can be realized, so that it is easy to adjust the angle of the seat back 200, and it can ensure that the seat back 200 can be tightly fitted to a vehicle seat after the safety seat is mounted.

[0025] As shown in FIGS. 1, 5 and 7, in an embodiment of the present invention, the lock driving member 500 includes a handle device 510. The handle device 510 is slidably connected to the base 100, and the handle device 510 is in transmission connection with the linkage member 400. The handle device 510 is embedded into the base 100, and the handle device 510 is slidable relative to the base 100, thereby facilitating manual operation.

[0026] As shown in FIGS. 1, 2, 5 and 7, the handle device 510 is mounted inside the base 100, and the handle device 510 is provided with a first hand-touch portion 511. The base 100 is provided with a first operation port 101 on its back portion, and the first operation port 101 is opposite the first hand-touch portion 511.

[0027] When an occupant is seated in a seating area of the safety seat, an operator can touch the first hand-touch portion 511 from the rear of the safety seat via the first operation port 101, and then the handle device 510 can be operated to slide relative to the base 100.

[0028] As shown in FIGS. 1, 3, 5 and 7, the base 100 is provided with a second operation port 102 on its front side, and the second operation port 102 is opposite the handle device 510. The handle device 510 can be touched through the second operation port 102. Under the condition of no occupant, the handle device 510 can be operated through the second operation port 102 to adjust the seat back 200, thereby enabling the seat back 200 of the safety seat mounted on a vehicle to be better fitted to the vehicle's seat.

[0029] Further, the handle device 510 is provided with a second hand-touch portion 512, the second hand-touch portion 512 is inserted into second operation port 102, and the second hand-touch portion 512 is slidable in the second operation port 102. Thus, when the safety seat is mounted on the vehicle seat, the second hand-touch portion 512 can be operated in front of the safety seat to slide the handle device 510 relative to the base 100, thereby realizing an unlocking operation of the locking member 300.

[0030] As shown in FIGS. 1, 5 and 7, the lock driving member 500 further includes a reset elastic member 520. The reset elastic member 520 is connected between the handle device 510 and the base 100, and the reset elastic member 520 is used for driving the handle device 510 to reset, so that the locking member 300 is locked to the seat back 200. The reset elastic member 520 drives the handle device 510 to reset, so that the handle device 510 drives the locking member 300 to reach the locked state via the transmission of the linkage member 400.

[0031] As shown in FIGS. 1, 4, 5, 6 and 7, the locking member 300 includes: a first lock pin 310 and a second lock pin 320. Each of the first lock pin 310 and the second lock pin 320 is slidably connected to the base 100, and each of the first lock pin 310 and the second lock pin 320 is in transmission connection with the linkage member 400.

[0032] In an upright state of the seat back 200, the first lock pin 310 and the second lock pin 320 are inserted into the lock holes 201 of the seat back 200, respectively, to lock the seat back 200. When the handle device 510 is manually operated, the handle device 510 drives the first lock pin 310 and the second lock pin 320 out of the lock holes 201 via the transmission of the linkage member 400. In this case, the seat back 200 can swing around rotating shafts 600 to adjust the angle of the seat back 200.

[0033] Further, the linkage member 400 includes: a first link rod 410 and a second link rod 420. The first link rod 410 and the second link rod 420 are connected to the first lock pin 310 and the second lock pin 320 in one-to-one correspondence, and each of the first link rod 410 and the second link rod 420 is in transmission connection with the lock driving member 500.

[0034] In one possible embodiment, the first link rod 410 and the second link rod 420 are hinged to the first lock pin 310 and the second lock pin 320 in one-to-one correspondence, so that the first lock pin 310 and the second lock pin 320 can be linked by the first link rod 410 and the second link rod 420.

[0035] In another possible embodiment, the first link rod 410 and the second link rod 420 are connected to the first lock pin 310 and the second lock pin 320 in one-to-one correspondence by flexible shafts. Thus, the first link rod 410 and the second link rod 420 can transmit pulling force, so that the first lock pin 310 and the second lock pin 320 can be pulled to unlock. Under the action of the reset elastic member 520, the handle device 510 drives the first link rod 410 and the second link rod 420 to reset, during which the flexible shafts push the first lock pin 310 and the second lock pin 320 to reset to the locked state.

[0036] In order to achieve multi-angle adjustment and locking of the seat back 200, a plurality of lock holes 201 may be provided, and the plurality of lock holes 201 are disposed at intervals around the rotating shaft 600 of the seat back 200, so that the seat back 200 can be locked at any angle position.

[0037] Further, the seat back 200 is hinged to the base 100 by rotating shafts 600, and two rotating shafts 600 are disposed coaxially. The seat back 200 is hinged to the base 100 by means of the two rotating shafts 600, ensuring that the inclination of the seat back 200 is smoothly adjusted, and facilitating the assembly of the seat back 200 with the base 100.

[0038] As shown in FIGS. 1 and 2, the base 100 is provided with a protrusion 103, the seat back 200 is provided with a first lateral arm 210 and a second lateral arm 220, the first lateral arm 210 and the second lateral arm 220 are spaced apart from each other, and the protrusion 103 is mounted between the first lateral arm 210 and the second lateral arm 220.

[0039] Specifically, the two rotating shafts 600 are inserted into the first lateral arm 210 and the second lateral arm 220 in one-to-one correspondence, and both the two rotating shafts 600 are inserted into the protrusion 103, so that compact assembly of the seat back 200 relative to the base 100 is realized by embedding the protrusion 103 between the first lateral arm 210 and the second lateral arm 220,.

[0040] Finally, it should be noted that the foregoing embodiments are only used to illustrate the technical solutions of the present invention, but not to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that it is still possible to modify the technical solutions described in the foregoing embodiments, or perform equivalent substitutions for some or all of the technical features therein.
