[0032] The technical solution of the present invention is further described below in conjunction with the accompanying drawings and specific embodiments.

[0033] like Figure 1 to Figure 15 As shown, the child safety seat of the present invention is fastened to the car seat 200 by a car safety belt 100 arranged on the car seat 200. The child safety seat includes a base assembly and a backrest 2. The base assembly includes a seat plate 1 for supporting the child's buttocks and an armrest 3 for the child to hold on to. The backrest 2 is located behind the seat plate 1 and extends in the up and down direction. The armrest 3 is respectively arranged on the left and right sides of the seat plate 1.

[0034] The child safety seat further comprises a first clamping mechanism 4, which is used to clamp the vehicle safety belt 100 so that the vehicle safety belt 100 can be tensioned, thereby stably fixing the child safety seat on the vehicle seat 200. The first clamping mechanism 4 is rotatably arranged on the seat plate 1. The first clamping mechanism 4 has a first position and a second position on the seat plate 1. When the first clamping mechanism 4 is in the first position, the first clamping mechanism 4 is away from the seat plate 1, and a passage for the vehicle safety belt 100 to pass through is provided between the first clamping mechanism 4 and the seat plate 1, such as Figure 1 , Figure 3 , Figure 7 , Fig. 9 , Fig.12 and Fig.13 When the first clamping mechanism 4 is in the second position, the first clamping mechanism 4 is close to the seat plate 1 to compress the vehicle seat belt 100 under the first clamping mechanism 4, as shown Figure 2 , Figure 4~Figure 6 , Figure 8 , Fig.10 , Fig.11 , Fig.14 and Fig.15 The first clamping mechanism 4 rotates relative to the seat plate 1 to switch between the first position and the second position.

[0035] The first clamping mechanism 4 includes a bottom plate 41. When the first clamping mechanism 4 is in the second position, the bottom plate 41 is located in the front or rear of the seat plate 1 and is sequentially connected to the seat plate 1. The upper end surface of the bottom plate 41 and the upper end surface of the seat plate 1 are located in the same plane, and the seat plate 1 and the bottom plate 41 together form a seat portion that supports the child's buttocks.

[0036] The connection between the first clamping mechanism 4 and the seat plate 1 can be located at the rear of the seat plate 1. In this embodiment, the left and right sides of the rear of the seat plate 1 are rotatably connected to the left and right sides of the first clamping mechanism 4 respectively. When the first clamping mechanism 4 is converted from the first position to the second position, the first clamping mechanism 4 rotates forward relative to the seat plate 1 around the rotation connection with the seat plate 1. When the first clamping mechanism 4 is in the second position, the bottom plate 41 is located at the front of the seat plate 1. Figure 1 , Figure 2 , Figure 5~Figure 15 shown.

[0037] The connection between the first clamping mechanism 4 and the seat plate 1 can also be located at the front part of the seat plate 1. In this embodiment, the middle part of the front part of the seat plate 1 is rotatably connected to the first clamping mechanism 4. When the first clamping mechanism 4 is in the first position, the first clamping mechanism 4 and the backrest 2 are respectively located at the front and rear ends of the seat plate 1. When the first clamping mechanism 4 is converted from the first position to the second position, the first clamping mechanism 4 rotates backward relative to the seat plate 1 around the rotation connection with the seat plate 1. When the first clamping mechanism 4 is in the second position, the bottom plate 41 is located at the rear part of the seat plate 1. Figure 3 and Figure 4 shown.

[0038] The child safety seat also includes a head support assembly 5 disposed on the backrest 2, and a guide structure 51 for guiding the car safety belt 100 is disposed on the head support assembly 5, and the guide structures 51 are respectively located on the left and right sides of the head support assembly 5, so that no matter whether the child safety seat is installed directly behind or to the side of the driver's seat, the car safety belt 100 can be guided by the guide structure 51. The car safety belt 100 includes a shoulder belt 101 and a waist belt 102. When the child safety seat is tied with the car safety belt 100, the path of the car safety belt 100 can adopt the following forms, and of course the path of the car safety belt 100 is not limited to the form given in this embodiment.

[0039] First path form: A first connector 201 is provided on the upper part of the car seat 200, and the upper end of the shoulder belt 101 is connected to the first connector 201, and then the shoulder belt 101 passes through the guide structure 51 located on the same side of the child safety seat as the first connector 201, and extends downward from the upper part of the backrest 2 of the child safety seat to the lower part of the backrest 2, and the upper and lower parts of the shoulder belt 101 on the backrest 2 are respectively located on the left and right sides of the backrest 2, and the lower part of the shoulder belt 101 passes around the armrest 3 from the outer side of the armrest 3 located on the same side as the lower part of the shoulder belt 101, and is connected to the second connector 202 provided at the bottom of the car seat 200, as shown in FIG. Figure 1 , Figure 2 , Figure 5 , Fig. 9 and Fig.10 The waist belt 102 extends from the connection with the second connecting member 202 through the armrest portion 3 located on one side near the second connecting member 202 to the armrest portion 3 on the other side, and passes through the armrest portion 3 on the other side to be connected to the third connecting member 203 disposed at the bottom of the car seat 200, as shown in FIG. Figure 1 to Figure 11 The armrest portion 3 is provided with a notch 31 with a forward opening and a "C" shape and a passage 32 passing through the left and right ends thereof. When the waist belt 102 passes through the armrest portion 3, it can pass through the passage 32. Figure 1 and Figure 2 As shown, it is also possible to pass through the gap 31, such as Figure 5 , Fig. 9 and Fig.10 shown.

[0040] Second path form: This path is different from the first path form in that the lower part of the shoulder strap 101 passes around the inner side of the armrest 3 on the same side as the lower part of the shoulder strap 101 and is connected to the second connecting member 202 provided at the bottom of the car seat 200, such as Figure 3 , Figure 4 , Figure 6 and Fig.11 When the shoulder strap 101 passes through the armrest portion 3, it can pass through the channel 32, as shown in FIG. Figure 3 and Figure 4 As shown, it is also possible to pass through the gap 31, such as Figure 6 and Fig.11 As shown, the rest is the same as the first path.

[0041] The third path form: This path is different from the first path form in that the upper and lower parts of the shoulder strap 101 on the backrest 2 are respectively located on the same side of the left and right sides of the backrest 2, and the shoulder strap 101 extends from its lower part on the backrest 2 along the left and right direction of the seat plate 1 from one side of the left and right sides of the seat plate 1 to the other side, and passes through the armrest part 3 located on the other side of the seat plate 1 to connect with the second connecting member 202 arranged at the bottom of the car seat 200, such as Figure 7 and Figure 8 As shown, the rest is the same as the first path.

[0042] When the first pressing mechanism 4 presses the vehicle safety belt 100, the shoulder belt 101 can be pressed only below the first pressing mechanism 4. Figure 1 , Figure 2 , Figure 5 , Figure 6 , Figure 9~Figure 11 As shown, the path of the automobile safety belt 100 can adopt the first path form or the second path form, and the connection between the first clamping mechanism 4 and the seat plate 1 can be located at the rear part of the seat plate 1 or at the front part of the seat plate 1 .

[0043] When the first pressing mechanism 4 presses the automobile safety belt 100, the shoulder belt 101 and the waist belt 102 can also be pressed under the first pressing mechanism 4 at the same time. Figure 3 , Figure 4 , Figure 7 and Figure 8 As shown, the path of the automobile safety belt 100 can adopt the third path form, and the connection between the first clamping mechanism 4 and the seat plate 1 can be located at the rear part of the seat plate 1 or at the front part of the seat plate 1. The path of the automobile safety belt 100 can also adopt the second path form, in which case the connection between the first clamping mechanism 4 and the seat plate 1 is located at the front part of the seat plate 1.

[0044] The child safety seat also includes a second clamping mechanism 6, which is used to clamp the shoulder strap 101 located on the backrest 2 against the backrest 2, thereby improving the comfort of the occupant when riding in the child safety seat. The second clamping mechanism 6 can be rotatably arranged on the seat plate 1. In this embodiment, the second clamping mechanism can be rotatably arranged at the rear of the seat plate 1. The second clamping mechanism 6 has a first position and a second position. When the second clamping mechanism 6 is in the first position, the second clamping mechanism 6 is away from the backrest 2, and there is a passage between the second clamping mechanism 6 and the backrest 2 for the shoulder strap 101 to pass through. Fig. 9 , Fig.12 and Fig.13 When the second clamping mechanism 6 is in the second position, the second clamping mechanism 6 is pressed on the backrest 2 to press the shoulder strap 101 on the backrest 2, as shown Fig.10 , Fig.11 , Fig.14 and Fig.15 When the second clamping mechanism 6 rotates relative to the seat plate 1, the second clamping mechanism 6 can be switched between the first position and the second position.

[0045] When the path of the automobile safety belt 100 adopts the first path form, the second path form or the third path form mentioned above, the shoulder belt 101 can be pressed against the backrest 2 by the second pressing mechanism 6 .

[0046] The child safety seat also includes a linkage member 7 that drives the second clamping mechanism 6 to rotate synchronously relative to the seat plate 1 when the first clamping mechanism 4 rotates relative to the seat plate 1. The linkage member 7 is arranged between the first clamping mechanism 4 and the second clamping mechanism 6. In this way, when the first clamping mechanism 4 is in the first position, the second clamping mechanism 6 is also just in the first position. When the first clamping mechanism 4 rotates from the first position to the second position, the second clamping mechanism 6 can be driven by the linkage member 7 to move from the first position to the second position. In this way, the linkage between the first clamping mechanism 4 and the second clamping mechanism 6 can be achieved. When the first clamping mechanism 4 and the second clamping mechanism 6 need to change their positions, only one of the first clamping mechanism 4 and the second clamping mechanism 6 needs to be operated, and there is no need to operate each separately, which is convenient to use.

[0047] In this embodiment, the linkage member 7 is a connecting rod, and the two ends of the connecting rod are respectively rotatably connected to the first clamping mechanism 4 and the second clamping mechanism 6. In this way, a four-bar linkage is formed between the first clamping mechanism 4, the seat plate 1, the second clamping mechanism 6 and the connecting rod. When the first clamping mechanism 4 rotates relative to the seat plate 1 to switch between the first position and the second position, the second clamping mechanism 6 can be synchronously driven to rotate relative to the seat plate 1 to switch between the first position and the second position through the four-bar linkage.

[0048] Preferably, the second clamping mechanism 6 is respectively arranged on the left and right sides of the seat plate 1. Figure 12~Figure 15 In this way, no matter the child safety seat is installed directly behind or to the side of the driver's seat, the shoulder belt 101 can be pressed against the backrest 2 by the second pressing mechanism 6 .

[0049] The above embodiments are only for illustrating the technical concept and features of the present invention, and their purpose is to enable people familiar with the technology to understand the content of the present invention and implement it accordingly, and they cannot be used to limit the protection scope of the present invention. Any equivalent changes or modifications made according to the spirit of the present invention should be included in the protection scope of the present invention.
