Description

Technical Field

[0001] The present application relates to the technical field of child seats, and in particular to a child safety seat and a vehicle. Background Art

[0002] Child safety seats are typically installed in the rear seats of vehicles, restraining children with seatbelts to reduce injuries in the event of a collision. Child safety seats typically consist of a base secured to the rear seat and a flexible seat body mounted on the base. The seat body is designed to accommodate the child.

[0003] However, there is at least one of the following problems in the related art: the traditional fixing methods for child safety seats are complex and diverse. For example, the child safety seat is installed on the rear seat by screw connection, which increases the difficulty of disassembly and assembly. Summary of the Invention

[0004] The technical problem to be solved by the present application is that the conventional fixing methods for child safety seats are complicated and varied. For example, the child safety seat is installed on the rear seat by screw connection, which increases the difficulty of disassembly and assembly.

[0005] To solve the above problems, the present application provides a child safety seat, which is arranged in the seat position of a vehicle; the child safety seat includes: a base structure composed of a backrest portion and a base portion, the base structure is used to install the child seat, and the base structure cooperates with the vehicle's seat belt structure; when the seat belt structure is in a buckled state, a restraining force is applied to the backrest portion and the base portion to limit them to the seat position.

[0006] Compared with the prior art, the technical effect achieved by adopting this technical solution is as follows: Compared with installing the child safety seat to the seat of the vehicle by screw connection, in this technical solution, the vehicle's safety belt structure is fully utilized to constrain the base structure, thereby playing the role of fixing the child safety seat to the seat. In the technical solution of this application, there is no need to add screw holes on the seat or the base structure to adapt to the screw connection method, which reduces the difficulty of assembling the child safety seat. Furthermore, in order to ensure that the restraining effect of the safety belt structure on the base structure is reliable, the base structure in this application is composed of two parts, namely, a backrest portion and a base portion. Therefore, the restraining effect of the safety belt structure on the backrest portion and the base portion at the same time further improves the stability of fixing the base structure to the seat position, avoiding the situation where the safety belt structure only constrains either the backrest portion or the base portion, resulting in the child safety seat falling off the seat position due to poor restraint effect.

[0007] In one example of the present application, the part of the seat belt structure used to cooperate with the backrest portion is defined as the first cooperation portion, and the part used to cooperate with the base portion is defined as the second cooperation portion; when the seat belt structure is in a buckled state, the first cooperation portion is vertically inclined and arranged at a front position of the backrest portion close to the base portion to apply a first restraining force to the backrest portion to limit it to the seat position; and the second cooperation portion laterally covers the position of the upper end of the base portion to apply a second restraining force to the base portion to limit it to the seat position.

[0008] Compared with the existing technology, the technical effect achieved by adopting this technical solution is: the corresponding first restraint force and second restraint force are applied to the backrest part and the base part respectively through the first matching part and the second matching part, thereby strengthening the effect of fixing the base structure to the seat position.

[0009] In one example of the present application, the base structure is provided with a left side and a right side arranged relatively to each other; the first end of the first matching portion is connected to the upper position of the inner chamber wall of the vehicle on the left side, and is arranged adjacent to the backrest portion; the second end of the second matching portion is connected to the lower position of the inner chamber wall of the vehicle on the left side, and is arranged adjacent to the base portion; the other end of the first matching portion and the other end of the second matching portion are connected by a locking member of the seat belt structure, and the locking member is used to cooperate with the fixed card slot arranged on the right side to make the seat belt structure enter a fastened state; wherein, when the locking member is separated from the fixed card slot, the seat belt structure changes from the fastened state to the unlocked state.

[0010] Compared with the existing technology, the technical effect achieved by adopting this technical solution is: the effect of disassembling and assembling the base structure is effectively achieved by utilizing the connection or separation between the locking member and the fixed slot.

[0011] In one example of the present application, the backrest portion includes: a backrest body portion, one end of which is connected to the base portion; a pillow portion, which is arranged at one end of the backrest body portion away from the base portion; a fastener, which is connected to the pillow portion, and the fastener is provided with a fastener groove for restraining the safety belt structure; wherein the fastener is located between the pillow portion and the backrest body portion.

[0012] Compared with the existing technology, the technical effect achieved by adopting this technical solution is: by hiding the fastener between the headrest portion and the backrest portion, the space formed between the headrest portion and the backrest portion is fully utilized, making the overall structure of the base structure compact. In addition, by constraining the safety belt structure through the fastener groove set in the fastener, it is avoided that when the child safety seat is fixed to the seat position, the safety belt structure is prevented from moving significantly relative to the base structure, thereby affecting the fixing effect of the safety belt structure on the child safety seat.

[0013] In one example of the present application, the buckle includes: a connecting portion, which is connected to one side of the headrest portion close to the backrest body portion; a bent portion, which is connected to one end of the connecting portion close to the backrest body portion, and a snap-fit ​​opening is formed between the bent portion and the connecting portion for the safety belt structure to enter the buckle slot.

[0014] Compared with the existing technology, the technical effect achieved by adopting this technical solution is that the structure of the buckle is simple and reliable, and the restraint of the safety belt structure is achieved.

[0015] In one example of the present application, the end of the curved portion used to form the snap-fit ​​opening has a first guide structure; the end of the connecting portion used to form the snap-fit ​​opening has a second guide structure arranged opposite to the first guide structure; wherein, in the process of the safety belt structure entering the buckle slot from the snap-fit ​​opening, the safety belt structure folds at least once.

[0016] Compared with the existing technology, the technical effect achieved by adopting this technical solution is: by setting the first guide structure and the second guide structure, the efficiency of adjusting the safety belt structure to enter the buckle groove is improved, and the difficulty of the safety belt structure to smoothly enter the buckle groove is reduced.

[0017] In one example of the present application, a receiving groove is provided at one end of the base portion near the backrest portion, and the base portion is also provided with a snap-fit ​​protrusion, which is arranged at the entrance position of the receiving groove, and the snap-fit ​​protrusion extends toward the direction close to the backrest portion; wherein, when the safety belt structure is in a snap-fit ​​state, at least part of the structure of the safety belt structure is buckled into the receiving groove by the snap-fit ​​protrusion.

[0018] Compared with the existing technology, the technical effect achieved by adopting this technical solution is: through the combined setting of the accommodating groove and the buckling protrusion, the fixing effect of the safety belt structure is improved, thereby ensuring the fixing effect of the base structure when the safety belt structure is in the buckled state.

[0019] In one example of the present application, the base portion is composed of a base body and an armrest structure; the armrests are arranged on the left and right sides of the base body, and a limiting gap is formed between the armrest on the right side and the backrest portion for the first matching portion to pass through.

[0020] In one example of the present application, the base structure comprises a plastic material; and the child seat comprises a flexible material.

[0021] Compared with the existing technology, the technical effect achieved by adopting this technical solution is: by setting the base structure to be plastic material, the stability of the seat belt structure in fixing it is improved compared with flexible materials; on the other hand, since the child seat is made of flexible material, on the one hand, the comfort of the child's riding is improved; on the other hand, the vibration transmitted from the base structure to the child seat during the driving of the vehicle is reduced, that is, the child seat has a vibration reduction effect.

[0022] On the other hand, the present application also provides a vehicle, comprising: a child safety seat as in any of the above examples.

[0023] Compared with the existing technology, the technical effect achieved by adopting this technical solution is: it can achieve the technical effect corresponding to any of the above examples, which will not be repeated here.

[0024] By adopting the technical solution of this application, the following technical effects can be achieved:

[0025] (1) Compared with installing the child safety seat to the seat of the vehicle by means of screw connection, in this technical solution, the vehicle's safety belt structure is fully utilized to constrain the base structure, thereby playing the role of fixing the child safety seat to the seat. In the technical solution of the present application, there is no need to add screw holes on the seat or the base structure to adapt to the screw connection method, which reduces the difficulty of assembling the child safety seat. Furthermore, in order to ensure that the restraining effect of the safety belt structure on the base structure is reliable, the base structure in the present application is composed of two parts, namely, a backrest portion and a base portion. Therefore, the stability of fixing the base structure to the seat is further improved by the restraining effect of the safety belt structure on the backrest portion and the base portion at the same time, avoiding the situation where the safety belt structure only restrains either the backrest portion or the base portion, resulting in the child safety seat falling off the seat due to poor restraint effect;

[0026] (2) By hiding the fastener between the headrest and the backrest, the space formed between the headrest and the backrest is fully utilized, making the overall structure of the base structure compact. In addition, by constraining the safety belt structure with the fastener groove provided in the fastener, it is avoided that when the child safety seat is fixed to the seat position, the safety belt structure is prevented from moving significantly relative to the base structure, thereby affecting the fixing effect of the safety belt structure on the child safety seat;

[0027] (3) By setting the base structure to be made of plastic material, the stability of the seat belt structure in fixing it is improved compared to flexible materials; in contrast, since the child seat is made of flexible material, on the one hand, the riding comfort of the child is improved; on the other hand, the vibration transmitted from the base structure to the child seat during the driving of the vehicle is reduced, that is, the child seat has a vibration reduction effect.

[0039] In order to make the above-mentioned objects, features and advantages of the present application more obvious and easy to understand, the specific embodiments of the present application are described in detail below with reference to the accompanying drawings.

[0040] An embodiment of the present application provides a child safety seat, which is arranged in a seat position of a vehicle; specifically, the child safety seat includes a base structure 100 composed of a backrest portion 110 and a base portion 120, the base structure 100 is used to install the child seat, and the base structure 100 cooperates with a seat belt structure 200 of the vehicle; when the seat belt structure 200 is in a buckled state, a restraining force is applied to the backrest portion 110 and the base portion 120 to limit them to the seat position.

[0041] Therefore, compared to installing a child safety seat to a vehicle seat using screw connections, this technical solution fully utilizes the vehicle's seatbelt structure 200 to constrain and cooperate with the base structure 100, thereby securing the child safety seat to the seat. In this technical solution, there is no need to add screw holes to the seat or base structure 100 to accommodate the screw connection method, which reduces the difficulty of assembling the child safety seat. Moreover, since the principle of its fixing method is similar to that of restraining an adult in a seat, the child safety seat can be secured by simply adjusting the seatbelt structure 200 to a buckled state.

[0042] Furthermore, to ensure that the safety belt structure 200 reliably restrains the base structure 100, the base structure 100 in the present application is composed of two parts, namely, a backrest portion 110 and a base portion 120. Thus, by the simultaneous restraint of the safety belt structure 200 on both the backrest portion 110 and the base portion 120, the stability of the base structure 100 in the seat position is further improved, avoiding the situation where the safety belt structure 200 only restrains one of the backrest portion 110 or the base portion 120, resulting in poor restraint and causing the child safety seat to fall out of the seat position.

[0043] Further, see Figure 1 , which is a schematic diagram of the cooperation relationship between a safety belt structure and a base structure 100 provided in an embodiment of the present application. Figure 2-Figure 7 , defining the part of the seat belt structure 200 used to cooperate with the backrest portion 110 as the first cooperation portion 210, and the part used to cooperate with the base portion 120 as the second cooperation portion 220; when the seat belt structure 200 is in the buckled state, the first cooperation portion 210 is vertically inclined and arranged at the front side position of the backrest portion 110 close to the base portion 120, so as to apply a first restraining force to the backrest portion 110 to limit it to the seat position; and the second cooperation portion 220 covers the upper end of the base portion 120 laterally to apply a second restraining force to the base portion 120 to limit it to the seat position.

[0044] Specifically, the first and second fitting portions 210 and 220 apply corresponding first and second restraining forces to the backrest portion 110 and the base portion 120 , respectively, thereby strengthening the effect of fixing the base structure 100 to the seat.

[0045] Preferably, the base structure 100 has a left side 101 and a right side 102 disposed opposite each other. The first end of the first mating portion 210 is connected to the upper portion of the vehicle's inner wall on the left side 101 and is disposed adjacent to the backrest portion 110. The second end of the second mating portion 220 is connected to the lower portion of the vehicle's inner wall on the left side 101 and is disposed adjacent to the base portion 120. The other end of the first mating portion 210 and the other end of the second mating portion 220 are connected by a latch 230 of the safety belt structure 200. The latch 230 is configured to engage with a fixed slot disposed on the right side 102 to engage the safety belt structure 200. When the latch 230 is separated from the fixed slot, the safety belt structure 200 transitions from the engaged state to the unlocked state. By utilizing the engagement or separation between the latch 230 and the fixed slot, the base structure 100 can be effectively assembled and disassembled.

[0046] Preferably, the backrest portion 110 includes, for example, a backrest body portion 111, a headrest portion 112, and a latch 113. One end of the backrest body portion 111 is connected to the base portion 120; the headrest portion 112 is disposed at an end of the backrest body portion 111 away from the base portion 120; the latch 113 is connected to the headrest portion 112 and has a latch slot 114 for restraining the seatbelt structure 200; the latch 113 is located between the headrest portion 112 and the backrest body portion 111.

[0047] By hiding the latch 113 between the headrest portion 112 and the backrest portion 110, the space formed between the headrest portion 112 and the backrest portion 110 is fully utilized, making the overall structure of the base structure 100 compact. In addition, by constraining the safety belt structure 200 with the latch groove 114 provided in the latch 113, it is avoided that the safety belt structure 200 undergoes a large positional movement relative to the base structure 100 when the child safety seat is fixed to the seat position, thereby preventing the safety belt structure 200 from moving significantly relative to the base structure 100, thereby affecting the fixing effect of the safety belt structure 200 on the child safety seat.

[0048] Preferably, the buckle 113 includes, for example, a connecting portion 115 and a curved portion 116. The connecting portion 115 is connected to a side of the headrest portion 112 close to the backrest body 111; the curved portion 116 is connected to an end of the connecting portion 115 close to the backrest body 111, and a snap-fit ​​opening 119 is formed between the curved portion 116 and the connecting portion 115 for the safety belt structure 200 to enter the buckle slot 114.

[0049] Preferably, the end of the curved portion 116 used to form the snap-fit ​​opening 119 has a first guide structure 117; the end of the connecting portion 115 used to form the snap-fit ​​opening 119 has a second guide structure 118 arranged opposite to the first guide structure 117; wherein, in the process of the safety belt structure 200 entering the buckle groove 114 from the snap-fit ​​opening 119, the safety belt structure 200 folds at least once.

[0050] Combine Figure 5 Preferably, a receiving groove 121 is provided at one end of the base portion 120 close to the backrest portion 110, and the base portion 120 is also provided with a snap-fit ​​protrusion 122, which is arranged at the entrance position of the receiving groove 121, and the snap-fit ​​protrusion 122 extends in a direction close to the backrest portion 110; wherein, when the safety belt structure 200 is in a buckled state, at least part of the structure of the safety belt structure 200 is buckled in the receiving groove 121 by the snap-fit ​​protrusion 122.

[0051] Preferably, the base portion 120 is composed of a base body 123 and an armrest structure 124; the armrests are arranged on the left side 101 and the right side 102 of the base body 123, and a limiting gap 125 is formed between the armrest on the right side 102 and the backrest portion 110 for the first matching portion 210 to pass through.

[0052] Preferably, the base structure 100 comprises a plastic material, and the child seat comprises a flexible material. By making the base structure 100 a plastic material, the stability of the seat belt structure 200 securing it is improved compared to flexible materials. Conversely, since the child seat is made of a flexible material, on the one hand, the riding comfort of the child is improved; on the other hand, the vibration transmitted from the base structure 100 to the child seat during vehicle operation is reduced, that is, the child seat has a vibration reduction effect.

[0053] In another aspect, embodiments of the present application further provide a vehicle. Specifically, the vehicle includes, for example, a child safety seat as described in the above embodiments. Accordingly, in this embodiment, the technical effects corresponding to any of the technical solutions in the above embodiments can be achieved, which will not be further elaborated here.
