However, the present disclosure is not limited to the embodiments described herein, and the present disclosure should be understood to include all modifications, equivalents, and alternatives included within the spirit and scope of the embodiments.

[0024] Although the present application will be described in detail below mainly with reference to a child safety seat, the side impact safety protection device according to the present application can also be applied in other suitable cases to provide cushioning protection to an infant in a child safety seat, and can realize automatic deployment and automatic folding.

[0025] Hereinafter, a side impact safety protection device 30 and a child safety seat 1 including the side impact safety protection device 30 according to the present application will be described in detail with reference to the accompanying drawings.

[0026] 1 and 2 are schematic diagrams showing the structure of a child safety seat 1 according to the present application, in which the child safety seat 1 is not disposed on a base 20 in FIG. 1, and the child safety seat 1 is disposed on the base 20 in FIG. 2. Specifically, the child safety seat 1 includes a main body 10, a base 20, and a side impact safety protection device 30 according to the present application. The side impact safety protection device 30 is provided on the base 20. When the main body 10 of the child safety seat 1 is not disposed on the base 20, as shown in FIG. 1, the side impact safety protection device 30 is in a folded state. Furthermore, when the main body 10 of the child safety seat 1 is disposed on the base 20, as shown in FIG. 2, the side impact safety protection device 30 disposed on the base 20 automatically protrudes outward to a deployed position to provide a cushioning protection function.

[0027] Further referring to FIG. 3, it is a schematic diagram showing the structure of the base 20 according to the present application. The base 20 includes an upper surface 21 and a side surface 22. In the process of using the child safety seat 1, the base 20 is fixedly installed on the seat of the car, and the main body 10 of the child safety seat 1 is fitted into the base 20. The side impact safety protection device 30 according to the present application includes a side impact protection block 31 and a driving member 34 for driving the side impact protection block 31. As shown in FIG. 3, the driving member 34 of the side impact safety protection device 30 is visible from the upper surface 21 of the base 20, and the side impact protection block 31 of the side impact safety protection device 30 is visible from the side surface 22 of the base 20.

[0028] 4 and 5, in which FIG. 4 shows the side impact protection block 31 of the side impact safety protection device 30 in the folded position, and FIG. 5 shows the side impact protection block 31 of the side impact safety protection device 30 in the unfolded position. Preferably, the protection block receiving groove 221 is disposed on the side surface 22 of the base 20, and the side impact protection block 31 of the side impact safety protection device is received in the protection block receiving groove 221 when the side impact safety protection device is in the folded state, thereby further receiving the side impact protection block 31 and reducing the overall folded size.

[0029] Hereinafter, the specific structure of the side impact safety protection device 30 according to the present application will be described in detail with reference to Fig. 6 and Fig. 7. Fig. 6 is a schematic diagram showing the specific structure of the side impact safety protection device 30 according to the present application, and Fig. 7 is another schematic diagram showing the specific structure of the side impact safety protection device 30 according to the present application. The side impact safety protection device 30 according to the present application mainly includes a side impact protection block 31, a traction member 32, a driving member 34, and a reset member 35. The driving member 34 is used to drive the side impact protection block 31 to the unfolded position or the folded position. One end of the traction member 32 is connected to the side impact protection block 31, the other end of the traction member 32 is connected to the driving member 34, and the reset member 35 is connected to the driving member 34 to fold the side impact protection block 31 via the driving member 34.

[0030] Specifically, based on the preferred embodiment shown in FIG. 6 and FIG. 7, as described above, the side impact protection block 31 in the folded position is disposed in the protection block receiving groove 221 of the side surface 22 of the base 20, and the side impact protection block 31 further includes a casing 311, a pivot 312, and a rear cover 313. The casing 311 and the rear cover 313 snap-engage with each other to improve the overall aesthetics of the side impact protection block 31. Furthermore, the casing 311 and the rear cover 313 jointly form a cavity for accommodating components and structures therein. Of course, in other embodiments, the side impact protection block 31 may be an integrally molded structure. The pivot 312 is disposed in the casing 311 of the side impact protection block 31. One end of the towing member 32 is connected to the pivot 312 of the side impact protection block 31. According to the illustrated preferred embodiment, the side impact safety protection device 30 further includes a torsion spring 36, which is sheathed on the pivot 312. Specifically, as shown in FIG. 8, a specific structure of the side impact protection block 31 is shown, and the rear cover 313 is removed in this drawing to clearly show the structures of the torsion spring 36 and the pivot 312, etc. The side impact safety protection device 30 preferably further includes a towing member fixing member 321. The towing member fixing member 321 is fixedly disposed in the casing 311 of the side impact protection block 31, and the towing member 32 is connected to the towing member fixing member 321. In addition, the pivot 312 of the side impact protection block 31 passes through the towing member fixing member 321, and preferably, as shown, the two torsion springs 36 are disposed on the portions of the pivot 312 located on both sides of the towing member fixing member 321, respectively. In this way, the side impact protection block 31 is pivotally connected to the towing member 32 via the towing member fixing member 321. Furthermore, one end of each torsion spring 36 is connected to or abuts on the side impact protection block 31, and the other end of each torsion spring 36 abuts on the protection block receiving groove 221. The torsion springs 36 always press the side impact protection block 31 into the folded position. According to another preferred embodiment, the side impact protection block 31 and the towing member fixing member 321 are integrally formed.

[0031] As mentioned above, one end of the towing member 32 is connected to the side impact protection block 31, and the other end of the towing member 32 is connected to the driving member 34. The driving member 34 preferably includes a pressing end 341 and a resetting end 342. The pressing end 341 is exposed outside the upper surface 21 of the base 20, so that the body 10 of the child safety seat 1 contacts the pressing end 341 of the driving member 34, thus triggering the driving member 34. The resetting end 342 of the driving member 34 is connected to the resetting member 35. According to a preferred embodiment shown in Figs. 6 and 7, the resetting member 35 is a spring.

[0032] Next, the detailed operation process of the side impact safety protection device 30 of the present application will be described with reference to Figures 9 and 10, which are schematic diagrams showing the structures of the side impact safety protection device 30 of the present application in different positions.

[0033] At the same time, referring to FIG. 7, when the main body 10 of the child safety seat 1 is placed on the base 20, the main body 10 contacts the pressing end 342 of the driving member 34 exposed outside the upper surface 21 of the base 20, and the gravity of the main body 10 itself pushes down the pressing end 342, which pulls the towing member 32 downward, thereby driving the towing member fixing member 321 to rotate in the clockwise direction indicated by the arrow in FIG. 7. By driving the towing member fixing member 321, the side impact protection block 31 is pivoted outward against the pressing action of the torsion spring 36, and thus reaches its deployed position to provide buffer protection. When the side impact protection block 31 is in the deployed position, the reset member 35 is compressed. Meanwhile, as shown in FIG. 9, when the main body 10 of the child safety seat 1 is removed from the base 20, the pressure of the gravity of the main body 10 itself on the pressing end 341 of the driving member 34 disappears. At this time, the towing member 32 moves upward under the action of the elastic force of the reset member 35, and at this time, the torsion spring 36 arranged between the side impact protection block 31 and the towing member 32 is released, as a result of which, under the action of the torsion spring 36, the side impact protection block 31 is pivoted downward to its folded position.

[0034] According to the side impact safety protection device 30 and the child safety seat 1 including the side impact safety protection device 30 according to the present application, the side impact safety protection device 30 has a simple structure and is easy to operate, and when the main body 10 of the child safety seat 1 is placed on the base 20, the side impact protection block 31 of the side impact safety protection device 30 can be automatically deployed to its deployed position to provide cushioning protection. Meanwhile, when the main body 10 of the child safety seat is removed from the base 20, the side impact protection block 31 of the side impact safety protection device 30 can be automatically folded by driving the reset member 35, and the operator does not need to perform a series of cumbersome operations to fold it, making the operation more convenient.

[0035] In the above embodiment of the present application, a child safety seat is used as an example for illustration. However, the present application may be applied to other types of seat devices in suitable forms. The present application also relates to a base adapted to mount the seat device. The base may, for example, include a body having at least one protrusion, the protrusion being located on at least one of the two sides close to the front edge of the body, and the above-mentioned side impact safety protection device is disposed on the protrusion.

[0036] However, since the features of the present disclosure can be embodied in various forms without departing from the characteristics of the present disclosure, the above-mentioned embodiments should not be limited to any of the above details unless otherwise specified, but should rather be broadly interpreted as being within the scope defined by the appended claims. Therefore, all modifications and changes that fall within the scope and limits of the claims, or equivalent solutions of such scope and limits, are intended to be included in the scope of the appended claims.
