[0023] According to some embodiments of the present disclosure, one aspect of the present disclosure provides a child safety seat comprising a seat body and a base for supporting the seat body. The base comprises a base body and a support mechanism mounted to the base body for supporting the child safety seat on a vehicle seat. The support mechanism includes a support member extending from the base body and reciprocally movable relative to the base body, and an adjustment device configured to adjust a position of the support member relative to the base body.

[0024] According to some embodiments of the present disclosure, another aspect of the present disclosure provides a base for a child seat. The base includes a base body and a support mechanism mounted to the base body for supporting the child seat on a vehicle seat. The support mechanism includes a support member extending from the base body and reciprocally movable relative to the base body, and an adjustment device configured to adjust a position of the support member relative to the base body.

[0025] The position of the child seat on the vehicle seat may need to be adjusted during use. For example, when adjusting the angle of the child seat's seat body, the base of the child seat on the vehicle seat needs to be moved accordingly. Some embodiments of the present disclosure provide an adjustable support element. If the position of the base of the child seat changes, the support element is adjusted accordingly so that it rests against a backrest of the vehicle seat to better support the child seat on the vehicle seat.

[0026] The child seat of each embodiment of the present disclosure and the base of the child seat are described in detail below in conjunction with the accompanying drawings of the present disclosure.

[0027] According to the Fig. In the embodiment illustrated in Figures 1-7, the child seat 10 comprises a seat body 20 and a base 30 for supporting the seat body 20. The base 30 further comprises a base body 40 and a support mechanism 50 connected to the base body 40. The support mechanism 50 stably supports the child seat 10 on the vehicle seat. The support mechanism 50 comprises a support element 51 and an adjustment device 52. The support element 51 protrudes from the base body 40, and the adjustment device 52 is configured to adjust and secure the position of the support element 51 relative to the base body 40.

[0028] According to one embodiment of the present disclosure, the seat body 20 is configured so that its inclination angle relative to the base 30 is adjustable. When the inclination angle of the seat body 20 is adjusted, the position of the base body 40 on the vehicle seat must be adjusted accordingly. Accordingly, the relative position of the support member 51 relative to the base body 40 can be adjusted simultaneously, i.e., the length of the support member 51 extending from the base body 40 can be adjusted so that the support member 51 can continue to rest against the backrest of the seat, thereby stably supporting and securing the child safety seat 10 on the vehicle seat. Fig. 1 and Fig. 2 show the support element 51 in a first and a second position, respectively. In the second position, the support element 51 protrudes relatively far from the substructure body 40.

[0029] It should be noted that the above or following description regarding the support element being configured to rest against the backrest of the vehicle seat does not imply that the support element is necessarily in contact with the backrest of the vehicle seat under normal circumstances. Rather, it includes the situation where the two are separated by a small distance and contact can only occur under certain circumstances. For example, when the child seat moves a small distance, the support element abuts the backrest of the vehicle seat to limit the movement of the child seat.

[0030] The base body 40 comprises an upper housing and a lower housing 41 which are assembled (in order to clarify the structure of the support mechanism 50, the upper housing is shown in the Fig. not shown). It is understood that the substructure body 40 may also consist of one piece in other embodiments.

[0031] According to Fig. 7, the support element 51 has a tubular and rod-shaped structure and comprises a support portion 510 and two connecting portions 511, each arranged on opposite sides of the support portion 510 and connected thereto. The support portion 510 is designed to bear against the backrest of the vehicle seat. In some embodiments, the support portion 510, together with the connecting portions 511, can be supported on a seat surface of the vehicle seat. Furthermore, a bending portion 512 can be provided between the connecting portion 511 and the support portion 510 and can be configured such that the length L of the support portion 510 is greater than the distance D between the ends E1, E2 of the connecting portion 511. A longer support portion 510 offers better support. Understandably, the connecting portions 511 can be in the Fig. 8, the support portion 510 extends directly from the support portion 510 without a bending portion, and in this case, the length of the support portion 510 is equal to the distance between the two connecting portions 511. The connecting portions 511 are provided with a plurality of positioning holes 513, each arranged along a front-rear direction of the child seat 10, and the positioning holes 513 cooperate with the adjusting device 52 to adjust and secure the position of the support member 51 with respect to the base body 40. The larger the number of positioning holes 513 and the more densely they are arranged, the larger the adjustment range of the support member 51 and the higher the adjustment accuracy.

[0032] In other embodiments, each connecting section 511 may be connected to a separate support section, ie each side of the base 30 is provided with a support element, so that the two support elements can be adjusted independently of each other.

[0033] The connecting sections 511 of the support element 51 are inserted into the substructure body 40 (see Fig. 4-6). Corresponding to the connecting part 511, the base body 40 is provided with guide rails 42 on both sides. In one embodiment, the guide rails 42 are provided on both sides of the lower housing 41. The connecting sections 511 are housed in the guide rails 42 and slide accordingly when the support element 51 is adjusted.

[0034] The adjustment device 52 comprises an actuating element 520, a driving element 521 connected to the actuating element 520 and at least one securing element 522 connected to the driving element 521 (see Fig. 4-6). The securing element 522 has a rod-shaped structure. In the Fig. In the embodiment illustrated in Figures 4-6, the adjustment device 52 includes a pair of locking elements 522, each arranged on two sides of the drive element 521. It is understood that in other embodiments, the adjustment device may include one or more than two locking elements. The locking elements 522 can be inserted into the positioning holes 513 of the support element 51 to secure the position of the support element 51 relative to the base body 40. The drive element 521 and the actuating element 520 are located in the same actuating plane (not labeled).When the actuating member 520 is moved from a first position to a second position along the actuating plane, it drives the driving member 521 to rotate clockwise or counterclockwise and releases the securing members 522 from the positioning holes 513, and when the actuating member 520 is moved from the second position to the first position, it drives the driving member 521 to rotate in the opposite direction and inserts the securing members 522 into the positioning holes 513. In this embodiment, the actuating member 520 is moved along a front-to-back direction of the actuating plane between the first position and the second position. According to the structure of the illustrated embodiment, one end of the driving member 521 is pivotally connected to the actuating member 520, and the other end of the driving member 521 is pivotally connected to the securing members 522.The drive element 521 is pivotally mounted on the base body 40 by being hinged to the lower housing 41 via a pivot point. The pivot point thus divides the drive element 521 into two segments, which are connected to the actuating element 520 and the securing element 522, respectively, enabling the actuating element 520 to control the reciprocating movement of the securing elements 522 by means of a lever action. The element shown in . Fig. The actuating element 520 shown in Figure 5 is in the first position in which the securing elements 522 are inserted into the positioning holes 513 and the position of the support element 51 is secured at this moment. Fig. The operating member 520 shown in Figure 6 is in the second position, where the locking members 522 are released from the positioning holes 513, and at this moment, the support member 51 can be freely adjusted to the desired positions. When the operating member 520 is moved from the first position to the second position along the front-to-back direction of the operating plane, for example, by the user's operation, the operating member 520 rotates the driving member 521 and releases the locking members 522 from the positioning holes 513. When the operating member 520 is moved from the second position to the first position, the driving member 521 rotates in the opposite direction, thereby inserting the locking members 522 into the positioning holes 513.

[0035] The adjustment device 52 may also include a spring element, such as a spring 523. The spring 523 bears against the actuating element 520 to exert an elastic force on the actuating element 520. When the actuating element 520 is released from the second position, the spring 523 can return the actuating element 520 to the first position. Furthermore, a limiting element 43 is provided on the base body 40 to limit the rotation of the driving element 521. In one embodiment, the limiting element 43 is provided on the lower housing 41. When the driving element 521 rotates, it engages the limiting element 43 to limit the range of rotation.

[0036] The base body 40 is provided with positioning slots 44 through which the securing elements 522 are guided. The securing elements 522 are displaceable in a transverse direction in the positioning slot 44, but immobile in the front-backward direction because they are restricted by the positioning slot 44. In one embodiment, the positioning slot 44 is provided on the lower housing 41. To further stabilize the connecting portions 511 of the support element 51 in the guide rails 42 and to prevent the connecting portion 511 from detaching from the guide rail 42, the base body 40 also includes stoppers 45 mounted above the guide rails 42 to limit the connecting portions 511 of the support element 51. In one embodiment, the stoppers 45 can be fastened above the guide rail 42 by screws.

[0037] Fig. 9-10 show another embodiment of the present disclosure having a different structure of the adjustment device than that shown in Fig. 4-6. In detail, the adjustment device 62 comprises an actuating element 620, a driving element 621 connected to the actuating element 620, and securing elements 622 connected to the driving element 621. The Fig. The actuating element 620 shown in Figure 9 is in a first position in which the securing elements 622 are inserted into the positioning holes 513, so that the position of the support element 51 is secured. Fig. The actuating element 620 shown in Figure 10 is in a second position in which the securing elements 622 are released from the positioning holes 513, so that the support element 51 can be freely adjusted to the desired positions at this moment. The driving element 621 is provided with guide slots 624, and one end of the securing element 622 is movably clamped in the guide slot 624. The guide slot 624 is configured to release the securing element 622 from the positioning slot 513 when the actuating element 620 is moved from the first position to the second position along the front-to-rear direction of the child seat 10, and to insert the securing element 622 into the positioning slot 513 when the actuating element 620 is moved from the second position to the first position along the front-to-rear direction of the child seat 10.In a more specific embodiment, an inclination angle is provided between the extending direction of the guide slot 624 and the front-rear direction of the child seat 10, which converts the movement of the actuating element 620 in the front-rear direction into the movement of the securing element 622 in the transverse direction perpendicular to the front-rear direction.

[0038] The adjustment device 62 may include a spring element, such as a spring 623, that bears against the drive element 621 to exert a spring force on the drive element 621 and the actuating element 620. The spring 623 may return the actuating element 620 to the first position when the actuating element 620 is released from the second position.

[0039] In the two embodiments of the adjusting devices 52, 62 described above, the actuating elements 520, 620 are arranged on the front side of the base body 40 and are exposed outside the base body 40, so that the user can easily and directly actuate the actuating elements 520, 620 to adjust the support element 51 without having to remove the child seat 10 from the vehicle seat.

[0040] In the embodiment described above, the support member 51 can be manually operated by the user to adjust the length of the support member 51 protruding from the base body 40 when the adjustment device 52, 62 unlocks it. In a modified embodiment, the support mechanism 50 further comprises a spring arrangement (not shown) that cooperates with the support member 51 to impart a continuous elastic thrust to the support member 51, so that the support member 51 can automatically extend from the base body 40 to a desired position when unlocked. For example, if the child seat 10 is moved forward in the vehicle, which requires an extension of the support member 51, the support member 51, when unlocked, automatically extends rearward until it rests against the backrest of the vehicle seat.

[0041] Fig. 11-13 show another embodiment of the present disclosure, in which an adjustment device 72 includes an operating member 720 and a securing member 722. The securing member 722 is attached to the support member 51. The operating member 720 is provided with a plurality of positioning grooves 725 arranged along the front and rear directions of the child seat 10. The larger the number of positioning grooves 725 and the more densely they are arranged, the larger the adjustment range of the support member 51 and the higher the adjustment accuracy. The operating member 720 is configured to move between a first position and a second position in a height direction of the child seat 10. Fig. 13 shows the actuating element 720 in a first position, in which the locking element 722 is inserted into the positioning groove 725 to secure the position of the support element 51. When the actuating element 720 is in the second position, the locking element 722 is released from the positioning groove 725, and the support element 51 can be freely adjusted to the desired positions at this moment. For example, when the actuating element 720 is pulled downward by the user to move from the first position to the second position, the positioning groove 725 of the actuating element 720 releases the locking element 722, i.e., it releases the support element 51, and the support element 51 can be freely adjusted at this moment.

[0042] The adjustment device 72 may also include a spring element, such as a spring 723, that bears against the actuating element 720 to exert a spring force on the actuating element 720. The spring 723 may cause the actuating element 720 to move back to the first position when the actuating element 720 is released from the second position.

[0043] In contrast to the previously described embodiments, the Fig. 11-13, only a single positioning hole 513 is provided for each connecting portion to secure the securing element 722 to the support element 51.

[0044] In other embodiments, the adjustment device may include a linear actuator (not shown) that drives the support member 51. The linear actuator may be, for example, an air cylinder, a hydraulic cylinder, a ball screw, etc. The linear actuator may actuate the support member 51 based on operating instructions. For example, the actuator directly actuates the connecting portions 511 of the support member 51 to move in a forward-backward direction to achieve positional adjustment of the support member 51 relative to the base body 40, thereby ensuring that the support member 51 rests against the backrest of the vehicle seat if the position of the child seat 10 needs to be adjusted to ensure the stability of the child seat 10. The linear actuator may also lock the support member 51 in the adjusted position.Compared to the previous embodiment, the use of an actuator eliminates the need to push and pull the support member by hand or allows for more effortless operation, thereby facilitating user operation.

[0045] It will be apparent to those skilled in the art that, in addition to the various adjustment device designs described above, other prior art adjustment devices may also be used, provided the adjustment device is capable of adjusting or locking the position of the support element in the forward-backward direction. The specific structure and mechanism of these other adjustment components are known to those skilled in the art, so they will not be described in detail here.

[0046] According to the safety seat and the base of the safety seat provided by various embodiments of the present disclosure, when the position of the safety seat on the vehicle seat needs to be adjusted, e.g., when the base of the safety seat needs to be moved forward away from the backrest of the vehicle seat, the length of the support member of the support mechanism extending from the base body can be increased to ensure that the support member continues to be in contact with or close to the backrest of the vehicle seat, so that the safety seat can be better stabilized on the vehicle seat. When the base of the seat needs to be moved closer to the backrest of the vehicle seat, only the length of the support member protruding from the seat body needs to be shortened.In another situation, when the seat belt is loosened due to the action of a child, the support element can be adjusted so that it continues to rest against the backrest of the vehicle seat and keeps the seat belt taut, thus ensuring the safety of children in the vehicle.
