[0059] The present disclosure will be described in detail below with reference to the accompanying drawings.

[0060] like Figures 1 to 6 As shown, the folding handle 10 of the child car seat 1 is arranged at the top of the backrest of the child car seat 1, so that the user can pull the folding handle 10 when folding the child car seat 1. However, the folding handle 10 can also be arranged at other positions of the child car seat 1, such as the side or lower part of the backrest of the child car seat 1, or even on the seat of the child car seat 1.

[0061] In order to enable the folding handle 10 to be automatically closed after the child car seat 1 is folded, the folding handle 10 according to an embodiment of the present disclosure includes a handle body 11 , a handle connector 12 and an elastic body.

[0062] Among them, Fig. 6A and Figure 8 As best seen, the handle body 11 includes a pulling portion 11A and a shaft portion 11B located at one end of the pulling portion 11A. The pulling portion 11A may be, for example, in the shape of a wing or a strip, so that the user can hook or pull the portion with his fingers to apply a force. The shaft portion 11B may be, for example, in the shape of a cylinder, so that the handle body 11 can pivot around the axis Z of the shaft portion 11B.

[0063] like Figure 5 , Figure 6 , Fig. 6A As can be best seen, the handle connector 12 serves to pivotally fix the handle body 11 to the child vehicle seat 1. On one hand, the handle connector 12 is fixed to the child vehicle seat 1, and on the other hand, the handle body 11 is pivotally connected to the handle connector 12 via its shaft portion 11B.

[0064] The handle connector 12 according to the present disclosure can adopt various embodiments as long as they can achieve the above-mentioned function of the handle connector 12. Fig. 6A , Figure 8 and Fig.11 In the illustrated embodiment, the handle connector 12 has a housing cavity 12A for the shaft portion 11B of the handle body 11 to pivot therein, and a mounting portion 12B for fixing to the child vehicle seat 1. The mounting portion 12B may be located at both ends or one end of the housing cavity 12A, and may be provided with mounting holes for fixing to the child vehicle seat 1 by means of bolts, screws, rivets or other connectors.

[0065] In order to enable the shaft portion 11B of the handle body 11 to pivot in the accommodating cavity 12A of the handle connecting member 12, in one embodiment, both ends of the shaft portion 11B of the handle body 11 are hollow (such as Fig. 6A , Figures 8 to 10 At the same time, pivot holes 12C (such as Fig. 6A , Figures 8 to 11 As best seen, two pivot pins 15 respectively pass through the pivot holes 12C on the handle connector 12 and respectively penetrate into the two ends of the shaft portion 11B of the handle body 11. Thus, the shaft portion 11B of the handle body 11 can pivot around the pivot pins 15 in the accommodating cavity 12A of the handle connector 12.

[0066] It should be understood that the present disclosure is not limited to this embodiment. In other embodiments, pivot holes 12C are provided on the side walls at both ends of the accommodating cavity 12A of the handle connector 12, and pivot shafts (not shown) may be provided at both ends of the shaft portion 11B of the handle body 11, and the pivot shafts pass through the pivot holes 12C on the handle connector 12; or pivot shafts (not shown) are provided on the side walls at both ends of the accommodating cavity 12A of the handle connector 12, and both ends of the shaft portion 11B of the handle body 11 are hollow, and the pivot shafts pass through both ends of the shaft portion 11B of the handle body 11; or, the outer surface of the shaft portion 11B of the handle body 11 is closely matched with the inner surface of the accommodating cavity 12A of the handle connector 12 in shape and size, so that the shaft portion 11B can pivot in the accommodating cavity 12A, and no additional pivot hole or pivot shaft is required. These other embodiments can all enable the shaft portion 11B of the handle body 11 to pivot in the accommodating cavity 12A of the handle connecting member 12 .

[0067] The elastic body is a key component to realize the automatic closing of the folding handle 10 , and is configured to force the handle body 11 to pivot toward the closed position.

[0068] In such Figures 6 to 8 In the embodiment shown, the elastic body is a torsion spring 13. The torsion spring 13 has two abutment ends 13A and 13B (see Figure 8 ), wherein one abutting end 13A abuts against the handle connecting member 12, and the other abutting end 13B abuts against the handle body 11. When the handle body 11 is subjected to the force of the user and pivots toward the open position, the torsion spring 13 is compressed and generates elastic force on the handle body 11 and the handle connecting member 12. Therefore, when the handle body 11 is no longer subjected to the force of the user, the elastic force of the torsion spring 13 will force the handle body 11 to pivot toward the closed position.

[0069] In such Fig. 9 , Fig.10 and Fig.12 In the embodiment shown, the elastic body is a contact strip 14 extending outward from the shaft portion 11B of the handle body 11. The contact strip 14 is pressed by the contact surface 121 of the handle connector 12 (see Fig.11 and Fig.12 ) is pressed downward to generate elastic force, and the elastic force of the contact strip 14 forces the handle body 11 to pivot toward the closed position. When the handle body 11 is subjected to the force of the user and pivots toward the open position, the contact strip 14 is further pressed downward by the contact surface 121 of the handle connecting member 12 to generate a greater elastic force on the handle body 11. Therefore, when the handle body 11 is no longer subjected to the force of the user, the elastic force of the contact strip 14 will force the handle body 11 to pivot toward the closed position.

[0070] Of course, in addition to the above two embodiments, the present disclosure may adopt other forms of elastomers, for example, a tension spring or an elastic rope, one end of which is fixed to the pulling portion 11A of the handle body 11, and the other end is fixed to the child car seat 1, thereby forcing the handle body 11 to pivot toward the closed position with the help of the tension spring or the elastic rope.

[0071] Next, a folding device for a child vehicle seat according to the present disclosure will be described.

[0072] like Fig.13 As shown, the folding device according to an embodiment of the present disclosure includes a folding handle 10 , a driving member 20 , a fixing member 30 and a pulling member 40 .

[0073] The backrest and the seat of the child car seat 1 are connected together by a pivot structure 1A, and the backrest and the seat are pivoted relative to each other by means of the pivot structure 1A. When the user pivots the backrest to a certain obtuse angle relative to the seat, that is, when the child car seat 1 is in an unfolded state for a child to sit on, in order to maintain the unfolded state, the pivot structure 1A needs to be locked so that it cannot rotate. To this end, the folding device according to the present disclosure is provided with a movable fixing member 30 near the pivot structure 1A, and the fixing member 30 is provided with a locking pin 31. When the child car seat 1 is unfolded, the locking pin 31 engages with the pivot structure 1A of the child car seat 1, so that the pivot structure 1A cannot rotate and the child car seat 1 is maintained in the unfolded state.

[0074] On the other hand, when the user is ready to fold the child vehicle seat 1 and the child vehicle, the user needs to disengage the locking pin 31 from the pivot structure 1A, thereby allowing the pivot structure 1A to rotate and fold the child vehicle seat 1 .

[0075] In order to conveniently achieve the disengagement of the locking pin 31 from the pivot structure 1A, a folding handle 10, a driving member 20 and a traction member 40 are provided in accordance with the folding device disclosed herein. With the aid of the driving member 20 and the traction member 40, the movement of the folding handle 10 can be transmitted to the fixing member 30, thereby driving the locking pin 31 to disengage from the pivot structure 1A, as described below.

[0076] First, the folding handle 10 is configured to drive the driving member 20 to move. In one embodiment, the outer surface of the shaft portion 11B of the handle body 11 of the folding handle 10 has a driving rib 11C inclined to the axis Z of the shaft portion 11B (see Fig. 9 and Fig.10 ), the driving member 20 has a driving inclined surface 20A (see Fig. 6A ), the driving rib 11C and the driving inclined surface 20A cooperate with each other, and when the handle body 11 pivots toward the open position, the driving rib 11C and the driving inclined surface 20A interact with each other, so that the driving member 20 moves. However, the present disclosure is not limited to this, and various methods can be adopted to enable the folding handle 10 to drive the driving member 20 to move. For example, the outer surface of the shaft portion 11B of the handle body 11 of the folding handle 10 can adopt a threaded mechanism, and the driving member 20 can adopt a worm structure that cooperates therewith, thereby converting the pivoting motion of the folding handle 10 into a linear motion of the driving member 20.

[0077] Secondly, the movement of the driving member 20 is further transmitted to the fixing member 30. In one embodiment, a traction member 40 is connected between the driving member 20 and the fixing member 30, so that when the driving member 20 moves, the movement of the driving member 20 is transmitted to the fixing member 30 via the traction member 40, thereby driving the locking pin 31 to disengage from the pivot structure 1A. Fig.14As shown, the pivot structure 1A can be rotated to fold the child car seat 1. Of course, the present disclosure is not limited thereto, and various methods can be adopted to transmit the movement of the driving member 20 to the fixing member 30. For example, the folding handle 10 and the driving member 20 can be arranged close to the fixing member 30, so that the driving member 20 can be directly connected to the fixing member 30, so that the movement of the driving member 20 is directly transmitted to the fixing member 30.

[0078] When the child car seat 1 is in the unfolded state, the locking pin 31 is inserted into the pivot structure 1A and engaged therewith, and the movement of the locking pin 31 inserted into the pivot structure 1A causes the movement of the fixing member 30, which is transmitted to the driving member 20 via the traction member 40, thereby driving the driving member 20 to move and causing the folding handle 10 to pivot toward the closed position, so that the folding handle 10 will not be opened at this time.

[0079] On the contrary, when the child car seat 1 is folded, the pivoting movement of the folding handle 10 toward the open position is transmitted to the fixing member 30 by means of the driving member 20 and the pulling member 40, and then the locking pin 31 is driven to disengage from the pivot structure 1A. Since the pulling member 40 is in a relaxed state and cannot pull the driving member 20 to move and make the folding handle 10 pivot toward the closed position, the folding handle 10 will remain in the open state. In this case, the elastic member in the folding handle 10 according to the present disclosure will play an active role and force the handle body 11 to pivot toward the closed position.

[0080] The foregoing embodiments and advantages are merely exemplary and should not be construed as limitations of the present disclosure. The description herein is intended to be illustrative rather than limiting the scope of the claims. A variety of alternatives, modifications, and variations will be apparent to those skilled in the art. The features, structures, and other characteristics of the exemplary embodiments described herein may be combined in a variety of ways to provide other and / or alternative exemplary embodiments.

[0081] Since the features of the present disclosure can be embodied in a variety of forms without departing from the characteristics of the present disclosure, it should also be understood that the above-mentioned embodiments are not limited to any details described above, unless otherwise noted, but should be broadly interpreted as being within the scope defined by the appended claims.
