[0041] 1 to 13, the present disclosure provides a combined seat / bed support switching mechanism 100 for a receiving device. The receiving device here is, for example, a stroller for carrying or pushing a baby, and includes a main frame body 200. The support switching mechanism 100 is disposed on the main frame body 200. The support switching mechanism 100 may be in the form of a seat to be attached to the main frame body 200 of the receiving device of this embodiment, which switches between a seat mode (shown in FIG. 1) and a carrycot mode (shown in FIG. 2) to allow an infant to sit in a seated position in the seat mode and to allow the infant to lie flat in a reclining position in the carrycot mode.

[0042] The support switching mechanism 100 includes two fixed holders 10 , a receiving support 20 , and a switching assembly 30 .

[0043] 1 and 2, two fixed holders 10 are fixed to either side of the main frame body 200. In this embodiment, each of the two fixed holders 10 has a seat mode positioning portion 11 and a carrycot mode positioning portion 12, and the seat mode positioning portion 11 and the carrycot mode positioning portion 12 are spaced apart by a certain angle on the fixed holder 10 (as shown in FIG. 3).

[0044] As shown in FIGS. 1 and 2 , the receiving support 20 is provided with rotatable holders 21 on both sides corresponding to the fixed holders 10. The rotatable holders 21 are rotatably disposed on the corresponding fixed holders 10, and the receiving support 20 is configured to rotatably swing between a seat position P1 (shown in FIG. 1 ) and a carrycot position P2 (shown in FIG. 2 ) as the rotatable holders 21 rotate. The receiving support 20 may be provided with a seat cover (not shown). The seat cover allows a baby to sit in a seated position when the receiving support 20 is in the seat position P1, and allows a baby to lie flat in a reclining position when the receiving support 20 is in the carrycot position P2. Therefore, when the receiving support 20 is rotatably swung to the seat position P1 and locked, it is in the seat mode. When the receiving support 20 is rotatably swung to the carrycot position P2 and locked, it is in the carrycot mode. As shown in Figures 1 and 2, the receiving support 20 in this embodiment is provided with a canopy frame 22, and the receiving support 20 can be provided with accessories 23, such as dinner plates or handrails, on rotating holders 21 on both sides, especially when the receiving support 20 is in seat position P1.

[0045] In this embodiment, the switching assembly 30 is provided with locking members 40 respectively connected to the drive levers 50 of the rotating holders 21 (shown in Figure 4). When the drive levers 50 are pulled by an external force, the drive levers 50 drive the locking members 40 to move away from their corresponding fixed holders 10, thereby unlocking the receiving support 20 and allowing it to pivotally swing between the seat position P1 and the carrycot position P2. After the external force is removed, the locking members 40 are driven to move towards their corresponding fixed holders 10 and engage with one of the seat mode positioning portion 11 and the carrycot mode positioning portion 12, thereby locking the receiving support 20. In this case, the receiving support 20 cannot pivotally swing between the seat position P1 and the carrycot position P2.

[0046] 9 to 12, the locking member 40 can be moved linearly between a locked position P3 and an unlocked position P4 by actuation of the drive lever 50. When the receiving support 20 is pivotally swung to the seat position P1, the locking member 40 can be aligned with the seat mode positioning portion 11, and the drive lever 50 drives the locking member 40 to move to the locked position P3 so that it engages with and locks into the seat mode positioning portion 11. Alternatively, when the receiving support 20 is pivotally swung to the carrycot position P2, the locking member 40 can be aligned with the carrycot mode positioning portion 12, and the drive lever 50 drives the locking member 40 to move to the locked position P3 so that it engages with and locks into the carrycot mode positioning portion 12. Furthermore, when the drive lever 50 drives the locking member 40 to move it to the unlocked position P4, the locking member 40 disengages from one of the seat mode positioning portion 11 and the carrycot mode positioning portion 12, thereby allowing the receiving support 20 to rotatably swing between the seat position P1 and the carrycot position P2.

[0047] In the above embodiment, the two fixed holders 10 each have a seat mode positioning portion 11 and a carrycot mode positioning portion 12, and the swivel holders 21 are each provided with a locking member 40 and a drive lever 50, so that the locking member 40 can engage with one of the seat mode positioning portion 11 and the carrycot mode positioning portion 12 between the two fixed holders 10 and the corresponding two swivel holders 21 to lock them, but the present disclosure is not limited to this. For example, it is also possible that only the fixed holder 10 has a seat mode positioning portion 11 and a carrycot mode positioning portion 12, and the swivel holder 21 is provided with a locking member 40 and a drive lever 50 corresponding to the fixed holder 10, so that the locking member 40 can engage with one of the seat mode positioning portion 11 and the carrycot mode positioning portion 12 to lock them.

[0048] In a preferred embodiment, as shown in FIG. 3 , the fixed holder 10 is formed as an integral unit, and the seat mode positioning portion 11 and the carrycot mode positioning portion 12 are each positioning grooves recessed from the fixed holder 10. As shown in FIG. 4 , the locking member 40 in this embodiment includes an actuating portion 41 and an engaging portion 42, and the engaging portion 42 extends laterally from one end of the actuating portion 41. When the locking member 40 is aligned with the seat mode positioning portion 11 and moved to the locking position P3, the engaging portion 42 is inserted into the seat mode positioning portion 11 to engage and lock (as shown in FIG. 10 ). In this case, the receiving support 20 is located at the seat position P1 and is in the seat mode. Furthermore, when the locking member 40 is aligned with the carrycot mode positioning portion 12 and moved to the locking position P3, the engaging portion 42 is inserted into the carrycot mode positioning portion 12 to engage and lock (as shown in FIG. 13 ). In this case, the receiving support body 20 is located in the carrycot position P2, and the stroller is in the carrycot mode.

[0049] 4, the driving lever 50 has a force application end 51 and a force resistance end 52 that are spaced apart from each other, and a shaft coupling portion 53 that is located between the force application end 51 and the force resistance end 52 and is shaft-coupled to the rotating holder 21 on which the driving lever 50 is disposed. Preferably, the shaft coupling portion 53 in this embodiment is a shaft hole, and the rotating holder 21 on which the driving lever 50 is disposed has a rotating shaft 211 (shown in FIGS. 10 to 13) that is disposed corresponding to the shaft coupling portion 53, and the driving lever 50 is inserted by the rotating shaft 211 in the shaft coupling portion 53 so that the driving lever 50 can be shaft-coupled to the rotating holder 21 on which the driving lever 50 is disposed.

[0050] 5 and 6 , the switching assembly 30 includes an operable operating member 60 and a traction member 70. The operating member 60 is disposed on the receiving support 20 and, in this embodiment, is located approximately at the handrail 201 of the main frame body 200. The traction member 70 is a cable in this embodiment, with one end connected to the force application end 51 and the other end connected to the operating member 60. The force resistance end 52 is rotatably and swingably connected to the actuation portion 41. When the operating member 60 is pulled, the force application end 51 is driven via the traction member 70, causing the drive lever 50 to swing around the axis of the shaft coupling portion 53. Meanwhile, the locking member 40 is driven to move between the locked position P3 and the unlocked position P4 via the force resistance end 52 connected to the actuation portion 41.

[0051] As shown in FIG. 6 , in this embodiment, the operating member 60 further includes a tensioning portion 61 and two sliders 62. The tensioning portion 61 is rotatably disposed on the receiving support 20 and is tensionable. The tensioning portion 61 has two guide rail portions 611. The two guide rail portions 611 are disposed at an angle. The two sliders 62 are disposed on the receiving support 20 and each have a guide channel 621 that engages with the guide portion 611. Each slider 62 has a joint (not shown) that connects to one end of the traction member 70. When the tensioning portion 61 is pulled, the two sliders 62 are guided by the two guide rail portions 611 and move toward each other, connecting the traction member 70 and driving the force application end 51 connected to the other end of the traction member 70.

[0052] As shown in FIG. 4, the switching assembly 30 further includes a reset member 80. The reset member 80 extends along the movement direction of the locking member 40, with one end abutting against one end of the actuating portion 41 away from the engaging portion 42 and the other end abutting against the inner side wall of the rotating holder 21 (shown in FIGS. 10 to 13). When the driving lever 50 drives the locking member 40 to move it to the unlocked position P4, the actuating portion 41 applies pressure to the reset member 80 to generate a reset elastic force, and when the driving lever 50 stops driving, the reset elastic force can reset the locking member 40 to the locked position P3.

[0053] The reset member 80 described above is a compression spring, and a boss 411 is provided at one end of the operating part 41 remote from the engagement part 42. The boss 411 is provided so that the reset member 80 can be attached in a sleeve-like manner, thereby preventing the reset member 80 from easily slipping away from the operating part 41 that it abuts. The operating part 41 is also provided with a rod part 412 that extends from the same side as the engagement part 42, and the drive lever 50 is provided with a receiving hole 521 at its force-resisting end 52. The drive lever 50 may be rotatably and swingably connected to the operating part 41 via the receiving hole 521 into which the rod part 412 is inserted.

[0054] As shown in FIG. 4, the locking member 40 further includes an extension portion 43 and a blocking portion 44, the extension portion 43 extending at one end of the engagement portion 42 away from the actuation portion 41, and the extension portion 43 and the actuation portion 41 extending in opposite directions. The blocking portion 44 is formed in a hook shape at one end of the extension portion 43 away from the engagement portion 42. As shown in FIG. 7, the rotating holder 21 has an opening 213 in its side wall 212, and the rotating holder 21 has a resilient arm 214 extending from the side wall 212 at the opening 213. The resilient arm 214 has a protrusion 215 at its end. The protrusion 215 protrudes laterally from the side wall 212. When the locking member 40 is in the locked position P3 and engaged with one of the seat mode positioning portion 11 and the carrycot mode positioning portion 12 to be locked, the opening 213 is aligned with the extension portion 43 and the protrusion 215 is pressed, causing the elastic arm 214 to incline from the opening 213 towards the extension portion 43 to block the blocking portion 44 and restrict the locking member 40 from moving out of the locked position P3. For example, in the seat mode (shown in FIG. 1 ), a vehicle seat (not shown) may be fixed to the receiving support body 20. The vehicle seat presses the protrusion 215 (shown in FIG. 8 ) corresponding to the side wall surface A at a position where the protrusion 215 is located, and in this case the elastic arm 214 blocks the blocking portion 44, and the receiving support body 20 is locked at the seat position P1. At this time, the blocking portion 44 can be prevented from disengaging from the locking position P3 after the vehicle seat is pressed against the receiving support 20, so that the vehicle seat cannot be adjusted from the seat position P1 to the carrycot position P2 after being pressed. In this way, back flipping of the vehicle seat caused by an incorrect use angle can be prevented, and as a result, the safety of the vehicle seat in use can be guaranteed. That is, the vehicle seat can be engaged only at the seat position P1.

[0055] As shown in FIG. 3, the fixed holder 10 has a first side surface 13, and the rotating holder 21 has a second side surface 216. The first side surface 13 faces the second side surface 216 when the rotating holder 21 is rotatably arranged on the fixed holder 10. As shown in FIGS. 3 and 9, the fixed holder 10 has two convex limiting portions 14 on the first side surface 13, and the rotating holder 21 has concave groove portions 217 on the second side surface 216 that correspond to the limiting portions 14. The groove portions 217 are arc-shaped and have a predetermined arc length. The limiting portions 14 limit the rotatable angle of the rotating holder 21 by taking a predetermined arc length as the movable stroke of the groove portions 217. In this embodiment, the angle is 30 to 45 degrees, preferably 42.5 degrees, but is not limited to this angle.

[0056] In actual operation, when the receiving support 20 is in the seat position P1 on the main frame body 200 and in the seat mode (as shown in Figure 1), and the receiving support 20 is capable of being switched to the carrycot position P2, the user can pull the operating member 60 to couple it with the drive lever 50 via the pulling member 70, and drive the locking member 40 to move from the locked position P3 to the unlocked position P4 (as shown in Figures 10 and 11), thereby disengaging the locking member 40 from the seat mode positioning portion 11 and rotating the receiving support 20 to the carrycot position P2 (as shown in Figure 12), and thus entering the carrycot mode. In this case, the operating member 60 is released, the locking member 40 is reset to lock position P3 by the resetting elastic force of the reset member 80 and engages and locks with the carrycot mode positioning part 12 (shown in Figure 13), the receiving support body 20 is locked in carrycot position P2, the protrusion 215 is pressed and the elastic arm 214 tilts towards the extension part 43 to block the blocking part 44 (shown in Figure 8) and prevent the locking member 40 from moving out of lock position P3. When switching the receiving support body 20 from carrycot mode to seat mode, the only difference from the above-mentioned operation is that after the locking member 40 disengages from the seat mode positioning part 11, the receiving support body 20 swings back from carrycot position P2 to seat position P1; the rest of the operation is the same. Therefore, details will not be given here.

[0057] From the above description, it is clear that the present disclosure has the following features:

[0058] 1. In the seat-bed dual support switching mechanism 100 of the receiving device according to the present disclosure, the locking member 40 is connected to the drive lever 50, and the seesaw action of the drive lever 50 drives the locking member 40 to move between the locked position P3 and the unlocked position P4 with little effort. This simple structure allows the receiving support 20 to be switched and locked between the seat mode and the carrycot mode, resulting in a simple structure and labor-saving operation.

[0059] 2. When the receiving device of the present disclosure is engaged with a vehicle seat, the receiving support body 20 can engage with the vehicle seat only when it is in the seat position P1, and when engaged with the vehicle seat, the elastic arm 214 can block the blocking portion 44, thereby restricting the locking member 40 from leaving the locking position P3, thereby preventing the vehicle seat from back-flipping due to an incorrect use angle and ensuring the safety of the vehicle seat in use.

[0060] 3. In the combined seat-bed support switching mechanism 100 for a receiving device according to the present disclosure, the switching assembly 30 further includes an operating member 60 on the receiving support 20, which is connected to the drive lever 50 via a traction member 70, so that the operating member 60 can be placed in a position convenient for a user to operate (for example, on the handrail 201 of the main frame body 200 as shown in Figures 1 and 2), and the movement of the locking member 40 can be remotely controlled, thereby achieving the convenience of remote operation.
