[0031] First Embodiment

[0032] As shown in Figures 1 to 4, the first embodiment of the present invention provides a child safety seat 10 including a seat body 100, a seat belt 200, a first barrier 300, a limiting member 510, a second barrier 600, and a clamp member 700.

[0033] Specifically, as shown in Figure 1, the seat body 100 includes a seat base 120 and a backrest 130 that are connected to each other and define a seating space 110. A child can sit in the seating space 110. The seat base 120 supports the child's buttocks, and the backrest 130 supports the child's back. In this embodiment, the seat base 120 and backrest 130 are made of plastic material, but are not limited to this.

[0034] As shown in Figures 1 and 2, the seat belt 200 includes a first connecting portion 210, a second connecting portion 220, and a third connecting portion 230. The first connecting portion 210 has a first end 211 and a second end 212. The first end 211 is positioned on the rear side of the backrest 130, and the second end 212 is positioned on the front side of the backrest 130, so that the first connecting portion 210 can secure a child in the seating space 110. In this embodiment, the child safety seat 10 further includes a first connecting member 410 and a second connecting member 420. The first connecting member 410 is positioned on the rear side of the backrest 103. The second connecting member 420 is positioned in the seating space 110. In the embodiment shown in Figures 1 and 2, the first connecting portion 210 includes a first shoulder belt 201 and a second shoulder belt 202 that are positioned side by side. The first end 211 of the first shoulder belt 201 and the first end 211 of the second shoulder belt 202 are both fixed to the first connecting member 410, and the second end 212 of the first shoulder belt 201 and the second end 212 of the second shoulder belt 202 are both connected to the second connecting member 420, so that the first shoulder belt 201 and the second shoulder belt 202 wrap around the rear side of the backrest 130 and pass into the seating space 110. In this way, the first shoulder belt 201 and the second shoulder belt 202 each secure the child's shoulders to the child safety seat 10. The second connecting member 220 has a third end (not shown in the drawing) and a fourth end 222. The third end is positioned on the front of the seat base 120. The fourth end 222 is connected to the first ends 211 of the two shoulder belts and to the second connecting member 420. Thus, the second connecting member 220 passes through the front and rear sides of the seat base 120. The third connecting member 230 has a fifth end 231 and a sixth end 232. The fifth end 231 is connected to the second connecting member 420. The sixth end 232 is located inside the seat base 120 by being connected to a buckle (e.g., a slide buckle). In this way, the seat belt 200 can secure a child in the seating space 110 to the child safety seat 10. In this embodiment, the first connecting member 410 is, for example, a five-way safety buckle, and the second connecting member 420 is, for example, a woven metal buckle.Of course, in other embodiments, the first connecting member 410 and the second connecting member 420 may be in other forms. Furthermore, in other embodiments, the seat belt 200 may be configured in other ways.

[0035] It should be understood that the terms "front" and "rear" as used herein refer specifically to the seating space 110. For example, the front of the backrest 130 refers to the side of the backrest 130 facing the seating space 110, and the rear of the backrest 130 refers to the side of the backrest 130 facing away from the seating space 110.

[0036] As shown in Figures 2 to 4, the first barrier 300 is fixed to the rear side of the seat base 120. Specifically, the seat base 120 is provided with an elongated housing section 121, and the first barrier 300 is attached to this housing section 121 by fasteners such as screws. The seat belt 200 comes into contact with the first barrier 300, and the first barrier 300 is configured to prevent deformation of the seat base 120. In this way, when the vehicle is involved in an accident such as a collision or sudden braking, the seat base 120 is pulled and dragged by the impact force of the seat belt 200, preventing deformation that would lengthen the seat belt 200 in the seating space 110 and cause the child's head to be displaced too far upward, thereby effectively reducing injuries to the child's body. Of course, in other embodiments, the first barrier 300 may be fixed to the rear of the backrest 130, the seat belt 200 may contact the first barrier 300, and the first barrier 300 may be configured to prevent deformation of the backrest 130. The child safety seat can effectively reduce the degree to which the child's head is displaced upward within the child safety seat in the event of an accident, thereby preventing injury to the child's body.

[0037] Furthermore, the first barrier 300 may protrude from the rear of the seat base 120 so that the seat belt 200 is separated from the rear of the seat base 120. In this case, the seat belt 200 does not directly contact the seat base 120, but directly contacts the first barrier 300. When the vehicle encounters an accident such as a shock or sudden braking, the impact force applied to the seat belt 200 can be absorbed by the first barrier 300, thereby preventing the seat base 120 from being deformed by the seat belt 200, preventing the portion of the seat belt 200 in the seating space 110 from becoming longer, and reducing the degree of upward displacement of the child's head.

[0038] Furthermore, the first barrier 300 has a higher hardness than the seat base 120. In this way, by placing the first barrier 300 on the seat base 120, the structural strength of the seat base 120 can be increased. In addition, when the vehicle is involved in an accident such as a collision or sudden braking, the seat base 120 becomes less likely to deform due to the pulling and dragging of the seat belt 200, preventing the portion of the seat belt 200 in the seating space 110 from becoming longer, and reducing the degree of upward displacement of the child's head.

[0039] Optionally, the first barrier 300 has a rod-like shape and is either fully or partially embedded in the rear side of the seat base 120. In this embodiment, the first barrier 300 is partially embedded in the rear side of the seat base 120 such that the seat belt 200 is in direct contact with the first barrier 300, and the seat belt 200 is positioned at a distance from the rear side of the seat base 120.

[0040] Furthermore, as shown in Figure 2, the limiting member 510 is configured to restrict and fix the seat belt 200 to the rear side of the backrest 130. In this way, the length of the portion of the seat belt 200 in the seating space 110 can be further limited, preventing the portion of the seat belt 200 in the seating space 110 from being pulled too far when the vehicle is involved in an accident such as a collision or sudden braking, and reducing the degree of upward displacement of the child's head.

[0041] Furthermore, in one embodiment, the first barrier 300 and the second barrier 600 may also have at least one restricting member 510 positioned thereon. In another embodiment, as shown in Figures 2 and 10, the child safety seat 10 further includes a fixing rod 520 (which may be optionally provided according to actual requirements), the fixing rod 520 is fixed to the rear side of the backrest 130, and the restricting member 510 is rotatably connected to the fixing rod 520.

[0042] The limiting member 510 includes a limiting portion 511, and by rotating the limiting member 510 in a direction approaching the backrest 130, the seat belt 200 can be pressed against the rear side of the backrest 130 via the limiting portion 511. In this way, by rotating the limiting member 510 in a direction approaching the backrest 130, the seat belt 200 can be pressed against the rear side of the backrest 130 via the limiting portion 511, which prevents the portion of the seat belt 200 within the seating space 110 from becoming longer in the event of an accident, and reduces the degree of upward displacement of the child's head. In this embodiment, the limiting portion 511 includes a plurality of limiting teeth 511a. When the limiting member 510 rotates in a direction approaching the backrest 130, the limiting teeth 511a abut the seat belt 200 against the rear side of the backrest 130, generating a large frictional force between the limiting teeth 511a and the seat belt 200, resulting in a better limiting effect. If it is necessary to adjust the length of the seat belt 200 in the seating space 110 according to the size of the child in the seating space 110, the limiting member 510 can be rotated away from the backrest 130 to release the biasing force of the limiting member 511 on the seat belt 200, thereby making it easier to adjust the length of the seat belt 200 in the seating space 110.

[0043] In this embodiment, as shown in Figures 2 and 10, the limiting member 510 includes a limiting body 512 having a substantially U-shaped structure and a limiting portion 511 positioned in the middle of the limiting body 512. Both ends of the limiting body 512 form a pivoting portion 512a for rotatably connecting to the first barrier 300 or the fixed rod 520. Of course, in other embodiments, the limiting member 510 may have other forms.

[0044] Furthermore, as shown in Figures 1 and 2, a perforation 131 is formed in the backrest 130, and the second end 212 of the seat belt 200 passes from the rear of the backrest 130 through the perforation 131, wraps around the front of the backrest 130, and enters the seating space 110. The fixing rod 520 is positioned opposite the perforation 131. In this way, the seat belt 200 can be effectively restricted and fixed. In this embodiment, two perforations 131 are arranged along the lateral direction of the backrest 130 for the first shoulder belt 201 and the second shoulder belt 202 to pass through, respectively, and are spaced apart from each other. Correspondingly, two restricting members 510 are positioned to bias the first shoulder belt 201 and the second shoulder belt 202 against the rear side of the backrest 130, respectively.

[0045] Furthermore, as shown in Figures 1 and 2, the vehicle includes an on-board safety belt 20, which is fitted to pass in front of the backrest 130 in order to secure the child safety seat 10 to the vehicle. The second barrier 600 is fixed to the backrest 130 and is configured to prevent deformation of the backrest 130. Since the child safety seat 10 is secured to the vehicle via the on-board safety belt 20 and the second barrier 600 fixed to the backrest 130 can prevent deformation of the backrest 130, it is possible to avoid deformation of the backrest 130 (for example, a reduction in its lateral dimension) when the vehicle encounters an accident such as an impact or sudden braking. As a result, the backrest 130 deforms due to the pulling action of the vehicle safety belt 20 (for example, its lateral dimension becomes smaller), which loosens the fastening between the vehicle safety belt 20 and the child safety seat 10, preventing the child safety seat 10 from being displaced and reducing the degree of upward displacement of the child's head.

[0046] Furthermore, as shown in Figures 1 and 2, the vehicle-mounted safety belt 20 is used to pass laterally through the front of the backrest 130, and the second barrier 600 is positioned laterally on the rear side of the backrest 130. In a specific mounting configuration of the second barrier 600, the first mounting rib 132 and the second mounting rib 133 are positioned laterally spaced apart on the rear side of the backrest 130, and both ends of the second barrier 600 are fixed to the first mounting rib 132 and the second mounting rib 133, respectively. In this way, the second barrier 600 can prevent the backrest 130 from deforming and prevent the vehicle-mounted safety belt 20 from loosening. Of course, the second barrier 600 can also be fixed to the rear side of the backrest 130 by other means. For example, the second barrier 600 may be completely embedded or partially embedded on the rear side of the backrest 130.

[0047] In this embodiment, as shown in Figures 2 and 11, the second barrier 600 preferably has a circular tubular structure, which is simple in structure and convenient to manufacture. Optionally, the circular tubular structure has an outer diameter of 12 mm to 13 mm and a thickness of 1 mm to 1.6 mm. In this embodiment, the circular tubular structure has an outer diameter of 12.7 mm and a thickness of 1.5 mm. However, it is not limited to a circular tube, and the second barrier 600 may be a rectangular tube.

[0048] Furthermore, as shown in Figure 1, a clamp member 700 is positioned on the front of the backrest 130, configured to clamp and secure the vehicle-mounted safety belt 20. This enhances the clamping and securing effect of the vehicle-mounted safety belt 20 by the clamp member 700.

[0049] Second Embodiment

[0050] A second embodiment of the present invention provides a child safety seat 10 including a seat body 100, a second barrier 600, and a clamp member 700. As shown in Figures 5 to 7, the child safety seat according to the second embodiment has substantially the same structure as the child safety seat according to the first embodiment, except that the seat belt 200, the first barrier 300, the limiting member 510, and the fixing rod 520 are omitted. In this second embodiment, the backrest 130 has perforations on both sides. These perforations are configured to allow the vehicle's onboard safety belt 20 to pass laterally across the front of the backrest 130, thereby securing the child safety seat 10 to the vehicle. Furthermore, a second barrier 600 is positioned near the perforations to prevent the onboard safety belt 20 from deforming the backrest 130.

[0051] Third Embodiment

[0052] A third embodiment of the present invention provides a child safety seat 10 including a seat body 100, a seat belt 200, a limiting member 510, and a fixing rod 520. As shown in Figures 1, 2, and 8 to 10, the child safety seat according to the third embodiment has substantially the same structure as the child safety seat according to the first embodiment, except that the first barrier 300, the second barrier 600, and the clamp member 700 are omitted.

[0053] Fourth Embodiment

[0054] A fourth embodiment of the present invention provides a child safety seat 10 including a seat body 100, a seat belt 200, a first barrier 300, a second barrier 600, and a clamp member 700. As shown in Figures 1 and 12, the child safety seat according to the fourth embodiment has substantially the same structure as the child safety seat according to the first embodiment, except that the limiting member 510 and the fixing rod 520 are omitted.

[0055] The above-described child safety seat 10 has at least the following technical effects.

[0056] In the child safety seat 10 described above, the seat belt 200 is wrapped around the front and rear of the seat body 100 to secure the child in the seating space 10. In addition, a first barrier 300 is positioned at the rear of the seat body 100, and the seat belt 200 comes into contact with the first barrier 300, preventing deformation of the seat body 100 by the first barrier 300. In this way, when the vehicle is involved in an accident such as a collision or sudden braking, the seat body 100 is pulled and dragged by the impact force of the seat belt 200, preventing deformation that would cause the length of the seat belt 200 in the seating space 110 to increase and displace the child's head too far upward, thereby effectively reducing injuries to the child's body.

[0057] The technical features of the embodiments described above can be combined in any way. For the sake of simplicity, not all possible combinations of the technical features of the embodiments described above are listed. However, all such combinations of technical features should be considered to fall within the scope of the present invention, as long as such combinations do not contradict each other.

[0058] The embodiments described above are merely illustrative of some embodiments of the present invention, and their descriptions are relatively specific and detailed. However, they should not be understood as limiting the scope of the patent of this application. Those skilled in the art should note that several further modifications and improvements can be made without departing from the concept of the present invention, and such modifications and improvements will fall within the scope of protection of this application. Accordingly, the scope of protection of the present invention shall be subject to the appended claims. [Explanation of symbols]
