For example, "connected" can be a fixed connection, such as welding, riveting, or bonding; it can also be a detachable connection, such as threaded connection, keyed connection, or pin connection; or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; or it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0020] Example 1 like Figure 1-4 As shown, the present invention proposes a tilting mechanism for adjusting the backrest of an infant carrier, including a carrier body 12. Both ends of the carrier body 12 near the side of the infant are fixedly installed with a carrying strap 13. A backrest 2 is hinged to the side of the upper end of the carrier body 12 away from the carrying strap 13. A backrest cushion 3 is laid on the upper surface of the backrest 2 and the upper surface of the carrier body 12. An inclined plate 9 is hinged to the bottom of the backrest body 12 on the side away from the back strap 13. Both ends of the backrest 2 on the side away from the back strap 13 are integrally formed with side plates 5. Mounting blocks 4 are fixedly installed on both sides of the inclined plate 9. The mounting blocks 4 are fixedly connected to the backrest 2 through connecting blocks 1. An arc-shaped sliding groove 7 is opened on the side plate 5. Sliding parts are fixedly installed on the side of the mounting blocks 4 away from the central axis of the inclined plate 9, and the sliding parts slide in conjunction with the sliding slots 7; the mounting block 4 on one side is detachably connected to the side plate 5 on the corresponding side through a limiting mechanism; the back plate 2 is elastically connected to both sides of the back chair body 12 through elastic connecting parts.

[0021] It should be added that the length of the inclined plate 9 is the same as the width of the back plate 2 to ensure sufficient support area; the connection block 1 can improve the stability of the connection between the mounting block 4 and the back plate 2.

[0022] In this embodiment, the sliding component includes sliding bolts 14. Multiple sliding bolts 14 are distributed in an arc shape and fixedly installed on the side of the mounting block 4. The rod of the sliding bolt 14 slides through the sliding slot 7.

[0023] It should be added that the width of the sliding slot 7 is 0.5-1mm larger than the diameter of the rod of the sliding bolt 14, which ensures smooth sliding; the arc-shaped distribution trajectory of the sliding bolt 14 is concentric with the rotation trajectory of the back plate 2 around the hinge, ensuring that the sliding bolt 14 always moves stably along the sliding slot 7 during the adjustment process.

[0024] In this embodiment, the limiting mechanism includes a limiting ring 8, a rod 15, a mounting bracket 16, and a spring 17; a plurality of limiting holes 6 arranged in a ring are provided through one side plate 5; the mounting bracket 16 is fixedly installed on the side of the mounting block 4 away from the inclined plate 9, and the rod 15 slides through the two side walls of the mounting bracket 16; the spring 17 is sleeved on the outer wall of the rod 15, the limiting ring 8 is fixedly sleeved on the outer wall of the rod 15, and both the spring 17 and the limiting ring 8 are located inside the mounting bracket 16; the limiting end of the rod 15 can be selectively inserted into the corresponding limiting hole 6.

[0025] It should be added that, in this embodiment, the diameter of the limiting opening 6 is 0.2-0.3mm larger than the diameter of the limiting end of the insertion rod 15, to ensure that the insertion rod 15 can be smoothly inserted without significant shaking; the internal space of the mounting bracket 16 can fully accommodate the spring 17 and the limiting ring 8, avoiding mutual interference between components during adjustment.

[0026] In this embodiment, the insertion rod 15 has an L-shaped structure; the limiting ring 8 is closer to the limiting opening 6 than the spring 17.

[0027] It should be added that, in this embodiment, the insertion rod 15 is easy for parents to operate with one hand; the limiting ring 8 and the insertion rod 15 are interference fit, which can prevent the limiting ring 8 from shifting during the sliding of the insertion rod 15 and ensure the stable transmission of the thrust of the spring 17.

[0028] Example 2 like Figure 1 As shown, based on Embodiment 1, the elastic connector is further defined. The elastic connector includes a connecting pad 10 and a connecting strap 11. The connecting pad 10 is fixedly installed on the side of the back panel 2, and the connecting pad 10 is fixedly connected to the side of the back chair body 12 through multiple connecting straps 11. The connecting strap 11 is an elastic band, and the two ends of the elastic band are fixedly connected to the connecting pad 10 and the back chair body 12 respectively.

[0029] It should be added that the elastic band, connecting pad 10, and backrest body 12 are all fixed by a double method of sewing and bonding, and the sewing thread is high-strength nylon thread to ensure a firm connection.

[0030] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
