[0044] Embodiments of the invention will now be described with reference to the accompanying drawings, in which similar element reference numerals denote similar elements.

[0045] Please see Figure 1 The child safety seat 100 of the present invention includes a base 10 and a body 20 selectively assembled to or removed from the base 10, and a seat belt guide device 30, such that the body 20 is assembled onto the base 10 as needed for use, and is used in conjunction with the base 10, or is removed from the base 10 for use alone, such as... Figure 2 and Figure 3 As shown. The main body 20 includes a base 20a and a backrest 20b and a seat 20c movably disposed on the base 20a. To make the main body 20 more suitable for children, as shown... Figure 4As shown, the backrest 20b is also provided with an adjustable headrest 20e and a headrest adjustment operation member 20f provided on the headrest 20e for adjusting the headrest 20e, but it is not limited to this. The seat 20c and the backrest 20b are pivotally connected to each other. The mutual pivoting of the seat 20c and the backrest 20b gives the body 20 three usage positions. Of course, in other embodiments, the mutual pivoting of the seat 20c and the backrest 20b can also give the body 20 two, four or five usage positions, so it is not limited to this. For ease of description, the three usage positions of the body 20 are respectively called the most reclining position, the middle position and the most upright position, which correspond to Figures 7 to 9 or Figures 10 to 12 The state shown. To ensure that the backrest 20b and seat 20c can be maintained when switched to the most reclined position, the middle position, or the most upright position, as shown... Figure 5 and Figures 10 to 14 As shown, each of the left and right side walls 26 of the backrest 20b is provided with a locking pin 20i, and each of the left and right side walls 21 of the base 20a is provided with three spaced-apart engaging holes 211. When the locking pin 20i engages with different engaging holes 211, the body 20 is positioned in the corresponding most flat position, middle position, or most upright position. To enable the locking pin 20i to be released, such as... Figure 4 As shown, a backrest adjustment operating component 20g is also provided at the rear of the backrest part 20b. A three-dimensional structural schematic diagram is provided below. Figure 6 The end of the contact foot 27 of the backrest adjustment mechanism 20g is connected to the locking pin 20i. By operating the backrest adjustment mechanism 20g, the user can disengage the locking pin 20i from the engaging hole 211, thus releasing the main body 20 from its most reclining, intermediate, or upright position. This allows the main body 20 to switch between these three positions. To ensure smoother and more reliable pivoting operation of the seat 20c and the backrest 20b, as... Figures 10 to 14As shown, a first guide assembly 23 and a second guide assembly 24 are provided between the base 20a and the backrest 20b for guiding the pivoting of the seat 20c and the backrest 20b. A third guide assembly 25 is provided between the base 20a and the seat 20c for guiding the pivoting of the seat 20c and the backrest 20b. The linkage structure 32 described below is formed in the first guide assembly 23. Specifically, in this embodiment, the first guide assembly 23 includes a first guide groove 23b located on the side wall 21 of the base 20a and a first guide member 23a located on the side wall 26 of the backrest 20b, extending into the first guide groove 23b and slidable along the first guide groove 23b. The second guide assembly 24 includes a second guide member located on the side wall 21 of the base 20a. The second guide 24a extends into the second guide groove 24b and is located on the side wall 26 of the backrest 20b. The third guide assembly 25 includes a third guide groove 25b on the side wall 21 of the base 20a and a third guide 25a on the side wall 22 of the seat 20c. The side wall 26 of the backrest 20b faces the side wall 21 of the base 20a, and the side wall 22 of the seat 20c faces the side wall 21 of the base 20a. The linkage structure 32 is formed on the first guide 23a, which can be understood as part of the first guide 23a, but is not limited thereto. The side wall 21 of the base 20a may also be provided with a gear adjustment mark structure 50 that is linked to the third guide 25a and corresponds one-to-one with the use position of the main body 20. Figures 10 to 12 As shown, during the process of pivoting between the seat 20c and the backrest 20b to switch the body 20 from the most reclining position to the most upright position, the second guide member 24a slides from the right end to the left end of the second guide groove 24b, the third guide member 25a slides from the right end to the left end of the third guide groove 25b, and the first guide member 23a slides from the upper end to the lower end of the first guide groove 23b, thereby driving the linkage structure 32 by the sliding first guide member 23a. It is worth noting that the first guide assembly 23, the second guide assembly 24, and the third guide assembly 25 do not need to be provided simultaneously between the base 20a and the seat 20c and between the base 20a and the backrest 20b; one of the two locations is sufficient. In other embodiments, the second guide assembly 24 and the third guide assembly 25 are deleted, or only the second guide assembly 24 is deleted, or only the third guide assembly 25 is deleted. For details regarding the specific structure and relationship of the second guide assembly 24, the third guide assembly 25, the base 20a, and the seat 20c; the specific structure and relationship of the back adjustment operation member 20g, the locking pin 20i, and the locking hole 211; and the specific structure and relationship of the seat 20c and the back support 20b, please refer to the Chinese patent application No. 201510757603.0. Therefore, they will not be described in detail here.

[0046] like Figures 1 to 3 ,as well as Figures 7 to 14 As shown, the seat belt guide device 30 is mounted on the child safety seat 100. The seat belt guide device 30 includes a barrier 31 movably mounted on the base 20a, a linkage structure 32 mounted on the backrest 20b and linked to the barrier 31, and a seat belt guide channel 35 mounted on the base 20a for the vehicle's seat belt to pass through. The seat belt guide channel 35 has a notch 35a to facilitate the entry and exit of the vehicle's seat belt. Specifically, in this embodiment, the seat belt guide channel 35 is located on the side wall 21 of the base 20a, and is safe... The notch 35a with the guide channel 35 is arranged facing upwards to facilitate operation by the operator, but is not limited thereto. The barrier 31 is slidably mounted on the base 20a, preferably on the left and right side walls 21 of the base 20a respectively. The backrest 20b drives the barrier 31 to cross or leave the seat belt guide channel 35 to close or open the notch 35a. Of course, in other embodiments, the barrier 31 can be assembled on the base 20a in a pivoting manner, and the backrest 20b drives the barrier 31 to pivot to open or close the notch 35a. Therefore, it is not limited thereto. When the body 20 switches from the most flat position or the middle position to the most upright position, the backrest 20b drives the barrier 31 to open the notch 35a through the linkage structure 32, as shown in the figure. Figure 12 or Figure 14 As shown, at this time, the car's seatbelt enters the seatbelt guide channel 35 through the open notch 35a, allowing the body 20 to be secured to the car seat by the seatbelt. For example, as... Figure 9 , Figure 12 and Figure 14 As shown, in this embodiment, the barrier 31 retracts into the base 20a and leaves the seat belt guide channel 35 when the body 20 switches to its most upright position; as Figure 7 , Figure 8 , Figure 10 , Figure 11 and Figure 13 As shown, in this embodiment, the barrier 31 pops out of the base 20a and crosses the seat belt guide channel 35 when the body 20 is switched to the most reclining position or the middle position. It is understood that by setting the linkage structure 32 on the seat 20c, the barrier 31 can be selectively driven to open or close the notch 35a during the switching of the body 20 between the most reclining position, the middle position and the most upright position, so it is not limited to this.

[0047] like Figures 10 to 14As shown, since the linkage structure 32 is formed on the first guide component 23, specifically on the first guide member 23a of the first guide component 23, the linkage structure 32 and the first guide member 23a are integrated, so that the first guide component 23 drives the blocking member 31 to move, thus simplifying the structure and operation process. Specifically, in this embodiment, the seat belt guide device 30 further includes a first elastic member 33 and a fixing member 34 built into the base 20a. The first elastic member 33 always has the tendency to drive the blocking member 31 to open the notch 35a, so as to facilitate the insertion of the seat belt. The seat belt guide channel 35 is located on the fixing member 34, and the first elastic member 33 is connected to the fixing member 34 and the blocking member 31. Of course, in other embodiments, the first elastic member 33 always has the tendency to drive the blocking member 31 to close the notch 35a, and the first elastic member 33 is connected to the blocking member 31 and the base 20, but it is not limited to this. For example, in this embodiment, the first elastic member 33 is a compression spring, but it is not limited to this example. To ensure that the linkage structure 32 reliably links the blocking member 31 to open or close the notch 35a, the blocking member 31 has a pushing portion 311 and an inclined transition portion 312 inclined relative to the pushing portion 311. During the process of the linkage structure 32 sliding from the inclined transition portion 312 to the pushing portion 311, it drives the blocking member 31 to close the notch 35a. Of course, in other embodiments, during the process of the linkage structure 32 sliding from the inclined transition portion 312 to the pushing portion 311, it drives the blocking member 31 to open the notch 35a; that is, the linkage structure 32, at the inclined transition portion 312 and... During the sliding process between the pushed parts 311, the blocking member 31 opens or closes the notch 35a, so this is not a limitation. To make the linkage between the linkage structure 32 and the blocking member 31 smoother, the linkage structure 32 can be a cylindrical structure, and a second elastic member 40 is connected between the first guide member 23a and the side wall 21 of the base 20a. Of course, in other embodiments, the second elastic member 40 can be connected between the linkage structure 32 and the side wall 21 of the base 20a, so this is not a limitation. For example, the second elastic member 40 is a tension spring, but it is not limited to this. It is worth noting that in other embodiments, at least one of the first elastic member 33 and the fixing member 34 in the seat belt guide device 30 can be deleted.

[0048] like Figures 10 to 14As shown, the child safety seat 100 of the present invention may further include a gear adjustment indicator structure, wherein the gear adjustment indicator structure 50 includes a first pivot member 51 and a second pivot member 52. The first pivot member 51 and the second pivot member 52 are each pivotally connected to the side wall 21 of the base 20a. Preferably, the middle portions of the first pivot member 51 and the second pivot member 52 are pivotally connected to the side wall 21 of the base 20a, such that the pivot point of the first pivot member 51 is located between its two ends, and the pivot point of the second pivot member 52 is located between its two ends. One end of the first pivot member 51 is connected to the third guide member 25a, and the other end of the first pivot member 51 is linked to one end of the second pivot member 52. The second pivot member 52 has a gear adjustment mark 521 corresponding to the usage position of the main body 20. The side wall 21 of the base 20a has a window 212 directly opposite one of the gear adjustment marks 521. Therefore, as... Figures 10 to 12 As shown, during the process of the main body 20 switching from the most reclining position to the most upright position by pivoting between the seat 20c and the backrest 20b, the third guide member 25a slides from the right end to the left end of the third guide groove 25b, thereby driving the first pivot member 51 to pivot. The pivoting first pivot member 51 then drives the second pivot member 52 to pivot accordingly, so that one of the position adjustment marks 521 on the second pivot member 52 faces the viewing window 212. For example, such as... Figure 7 As shown, when the main body 20 is in its most flat position, the viewing window 212 is directly aligned with one of the gear adjustment indicators 521; as Figure 8 As shown, when the main body 20 is in the middle position, the viewing window 212 is directly opposite the second gear position in the gear adjustment indicator 521; as Figure 9 As shown, when the main body 20 is in the most upright position, the viewing window 212 is directly opposite the three gears in the gear adjustment mark 521.

[0049] Referring to the accompanying drawings, the switching of the main body of the child safety seat of the present invention between the most reclined position, the intermediate position, and the most upright position will be described: When it is necessary to... Figure 7 , Figure 10 or Figure 13 The body 20 in the most supine position shown is... Figure 8 or Figure 11 When the main body 20 is switched to the intermediate position, the user operates the backrest adjustment mechanism 20g. The backrest adjustment mechanism 20g causes the locking pin 20i to disengage from the rightmost engaging hole 211 of the base 20a, thereby allowing the backrest 20b and base 20a to pivot relative to each other. When the backrest 20b and base 20a pivot to the point where the main body 20 is in the intermediate position... Figure 8 or Figure 11When the device is in the middle position as shown, the user releases the backrest adjustment mechanism 20g, and the locking pin 20i engages with the locking hole 211 in the middle of the base 20a. (See diagram). Figure 8 or Figure 11 As shown; when body 20 continues to move towards Figure 9 , Figure 12 or Figure 14 When the state switch is shown, the user operates the backrest adjustment mechanism 20g again. The backrest adjustment mechanism 20g drives the locking pin 20i to disengage from the locking hole 211 in the middle of the base 20a, thereby allowing the backrest part 20b and the base 20a to pivot relative to each other. When the backrest part 20b and the base 20a pivot to the point that the main body 20 is in the position shown, the user can adjust the backrest adjustment mechanism 20g. Figure 9 , Figure 12 or Figure 14 When the user releases the backrest adjustment mechanism 20g, the locking pin 20i engages with the leftmost locking hole 211 of the base 20a. (See diagram). Figure 12 or Figure 14 As shown. Specifically, during the process of the body 20 switching from its most supine position to its most upright position, when the body 20 is in its most supine position, as... Figure 10 As shown, since the third guide 25a is located at the right end of the third guide groove 25b, the gear adjustment mark 521 is aligned with the viewing window 212 at this time, as shown in the status diagram. Figure 7 As shown; simultaneously, the first guide member 23a is located at the upper end of the first guide groove 23b, causing the linkage structure 32 to push the blocking member 31 across the seat belt guide channel 35 and close the notch 35a, and the first elastic member 33 is in a compressed state. When the body 20 is in the middle position, as Figure 11 As shown, since the third guide member 25b slides to the middle of the third guide groove 25a, the second gear in the gear adjustment mark 521 is directly opposite the viewing window 212, as shown in the status diagram. Figure 8 As shown; simultaneously, the first guide member 23a slides to the middle of the first guide groove 23b, and the linkage structure 32 on the first guide member 23a still abuts against the pushed part 311 of the barrier member 31, thereby keeping the barrier member 31 in a state of crossing the seat belt guide channel 35, and the first elastic member 33 is still in a compressed state. When the body 20 is in the most upright position, as Figure 12 As shown, since the third guide 25a slides to the left end of the third guide groove 25b, the third gear in the gear adjustment mark 521 is now aligned with the viewing window 212, as shown in the diagram. Figure 9 As shown; simultaneously, the first guide member 23a slides to the lower end of the first guide groove 23b, at which point the first elastic member 33 is released, causing the linkage structure 32 and the inclined transition portion 312 of the barrier member 31 to abut against each other, thereby keeping the barrier member 31 away from the seat belt guide channel 35, as shown in the diagram; Figure 9 As shown.

[0050] Compared with the prior art, the seat belt guide device 30 of the present invention includes a barrier 31 movably disposed on the base 20a, a linkage structure 32 disposed on the backrest 20b or the seat 20c and linked to the barrier 31, and a seat belt guide channel 35 disposed on the base 20a for the seat belt of the vehicle to pass through, the seat belt guide channel 35 having a notch 35a; during the switching of the body 20 between different usage positions, the backrest 20b or the seat 20c selectively drives the barrier 31 to open or close the notch 35a through the linkage structure 32, at which time the seat belt enters the seat belt guide channel 35 through the opened notch 35a, thereby allowing the individual... The main body 20 is fixed to the car seat, or assembled with the base 10 and then fixed to the car seat together with the base 10, thus making the child safety seat 100 of the present invention have diverse and flexible usage modes; more importantly, the power for the barrier 31 to open or close the notch 35a of the seat belt guide channel 35 comes from the operator's pivot adjustment between the backrest 20b and the seat 20c, that is, the barrier 31 opens or closes the notch 35a of the seat belt guide channel 35 as the backrest 20b and the seat 20c pivot, thus simplifying the operator's operation and the structure of the seat belt guide device 30 of the present invention.

[0051] It is worth noting that in other embodiments, the child safety seat 100 may only include the body 20 and the aforementioned seat belt guide device 30; similarly, in other embodiments, the body 20 may be designed to only include the base 20a and the backrest 20b movably disposed on the base 20a. Correspondingly, the three usage positions of the body 20 are obtained by the movement of the backrest 20b relative to the base 20a; since the body 20 does not have a seat 20c, correspondingly, the body 20 in other embodiments only retains the first guide component 23 and the second guide component 24, and is not limited to the above examples.

[0052] The above-disclosed embodiments are merely preferred embodiments of the present invention and should not be construed as limiting the scope of the present invention. Therefore, any equivalent variations made in accordance with the claims of the present invention are still within the scope of the present invention.
