[0028] The present invention provides a backrest adjustment mechanism 1 for a baby carriage.

[0029] In the embodiment of the present invention, Figures 1 to 6 As shown, the backrest adjustment mechanism 1 of the baby carriage includes a backrest angle adjustment component 11 and a movable connection component 12. The backrest angle adjustment component 11 includes at least one adjustment belt 111 and an adjustment component 112 for controlling the tightness of the adjustment belt 111. The inclination angle of the backrest 21 is adjusted by adjusting the tightness of the adjustment belt 111. The movable connection component 12 includes at least one connecting member 121 and a guide member 122 capable of moving the connecting member 121 along a predetermined direction. The two ends of the adjustment belt 111 are respectively connected to the corresponding connecting members 121. When the adjustment belt 111 is adjusted in tightness by the adjustment component 112 or is driven during the process of folding and unfolding the baby carriage 2, the connecting member 121 is synchronously driven by the adjustment belt 111 to move upward or downward along the guide member 122 When the stroller needs to be folded, the adjustment belt 111 is adjusted to a loose state by the adjustment component 112, and the non-locking part of the adjustment belt 111 becomes longer. At this time, the connecting piece 121 can drive the end of the adjustment belt 111 to slide upward along the guide piece 122. The adjustment belt 111 does not produce any constraint in the process, so as not to affect the folding of the stroller. When it is necessary to lean on, the adjustment belt 111 is adjusted to a tight state by the adjustment component 112, and the non-locking part of the adjustment belt 111 becomes shorter. At this time, the connection can drive the end of the adjustment belt 111 to slide downward along the guide piece 122. The adjustment belt 111 will not hinder the angle adjustment of the backrest 21 in the process, so that the backrest 21 can be further rotated in the upright direction, so that the inclination angle of the backrest 21 can support infants and young children to lie down upright, thereby increasing comfort.

[0030] In the embodiment of the present invention, the material of the adjustment belt 111 may refer to the prior art, wherein preferably, the adjustment belt 111 is a braided belt, which can be better adapted to the use of baby products due to its softness and high toughness.

[0031] In an embodiment of the present invention, the guide member 122 is provided with a guide groove 1221, and the connecting member 121 includes a sliding portion 1211 for cooperating with the guide groove 1221, and the sliding portion 1211 can slide up and down in the guide groove 1221, and the sliding portion 1211 drives the end of the adjustment belt 111 to move in the guide groove 1221 according to the non-locking length of the adjustment belt 111. It can be understood that the sliding mode of the sliding portion 1211 is various. In some other embodiments, the sliding portion 1211 can also be a ring structure, and the guide member 122 does not need to be provided with a guide groove 1221. The ring structure is directly sleeved on the guide member 122. Among them, the preferred embodiment of the present invention is Figure 6As shown, the sliding portion 1211 is a cylindrical structure extending into the guide groove 1221. The advantage of this extending structure is that it is more stable to use. Compared with the sleeve connection, the snap-fit ​​connection method is more stable.

[0032] Specifically, in order to enable the connecting member 121 to stably control the end of the adjusting belt 111, the connecting member 121 also includes a connecting portion 1212 for fixing the adjusting belt 111. The connecting portion 1212 is provided with a socket 12121. The end of the adjusting belt 111 extends into and is wrapped around the socket 12121 for fixing. This connection method is simple and stable, and is suitable for assembly and actual use.

[0033] Furthermore, during the use of the present invention, the end of the adjustment belt 111 will be driven by the connecting piece 121 to form a small drag at the position of the socket 12121. In order to protect the end of the adjustment belt 111, the outer frame of the socket 12121 is formed with a protrusion 12122 for protecting the adjustment belt 111 at the docking point of the socket 12121 in the direction in which the adjustment belt 111 extends.

[0034] Furthermore, in some preferred embodiments of the present invention, the sliding portion 1211 and the connecting portion 1212 are integrally formed. The advantage of the integral forming is that the structure is more stable. At the same time, the sliding portion 1211 is formed with a curved structure 1213 for docking with the guide member 122 in a direction away from the connecting portion 1212. The advantage of the curved structure 1213 is that it can be more conveniently connected to the frame. When docking with the frame, the curved structure 1213 is aligned with the frame, and part of the frame is extended into the curved structure 1213 for installation.

[0035] In an embodiment of the present invention, the guide member 122 is disposed on the frame of the baby carriage. In order to more smoothly control the movement of the guide member 122, the guide groove 1221 corresponds to an opening at one end of the sliding portion 1211, and the connecting portion 1212 extends out of the opening and is connected to the adjustment belt 111.

[0036] It can be understood that when the guide member 122 is provided on the frame, the guide member 122 can be provided at various positions, mainly limited to the handlebar tube, the foot tube and other parts with a certain expansion distance. The guide member 122 can meet the movement of the connecting member 121 for a certain distance, so that the adjustment belt 111 does not affect the folding of the vehicle and the inclination adjustment of the backrest 21. Figure 5 and Figure 6 As shown, in the embodiment of the present invention, the guide member 122 is disposed on the front leg tube of the frame.

[0037] In an embodiment of the present invention, the adjustment component 112 includes a main body 1121 and a first accommodating chamber 1122 and a second accommodating chamber 1123 for extending into the adjustment belt 111, wherein the length of a partial section of the adjustment belt 111 passing through the first accommodating chamber 1122 and the second accommodating chamber 1123 is locked by the adjustment component 112, and the locked partial section length is not used to adjust the inclination degree of the backrest 21.

[0038] Specifically, in order to facilitate the use of the adjustment component 112, the adjustment component 112 is provided with a limit button 1124. When the limit button 1124 is pressed, the adjustment component 112 releases the lock on the adjustment belt 111. The locking and unlocking of the adjustment belt 111 by the adjustment component 112 is controlled by a button, which is convenient for daily use.

[0039] Furthermore, when the locking section of the adjustment belt 111 needs to be lengthened, it is necessary to drag the portion of the adjustment belt 111 passing through the adjustment component 112. In order to facilitate the dragging action, the section of the adjustment belt 111 passing through the first accommodating chamber 1122 and the second accommodating chamber 1123 is provided with a pulling member 13 for conveniently adjusting the length of the adjustment belt 111. When the aforementioned steps need to be performed, the locking section of the adjustment belt 111 can be lengthened by pulling the pulling member 13.

[0040] Specifically, the pulling member 13 includes an abutment portion 131 arranged parallel to the adjustment belt 111 and a pulling portion 132 used for external force pulling. The abutment portion 131 and the pulling portion 132 are an integrally formed ring body. The advantage of the integral molding is that the structure is relatively stable. In addition, in order to save more effort when pulling the pulling member 13, the pulling portion 132 is at least partially bent to the abutment portion 131. The bent pulling portion 132 can be more adaptable to the hand structure. When pulling, the hand and the pulling portion 132 can fit together, thereby achieving a labor-saving effect.
