DETAILED DESCRIPTION

[0025] The specific implementation of the present invention is further described below in conjunction with the accompanying drawings and embodiments. The following embodiments are only used to more clearly illustrate the technical solution of the present invention, and cannot be used to limit the protection scope of the present invention.

[0026] See also Figure 1 , the present invention relates to a 360-degree rotating seat for a child stroller, comprising a reversing mechanism and a seat connecting base 8, the reversing mechanism comprising a fixed disk 1, a rotating disk 3, a first driving mechanism and a second driving mechanism;

[0027] The rotating disk 3 is arranged on the fixed disk 1, and the rotating disk 3 and the fixed disk 1 can rotate. The rotating shaft 101 of the fixed disk 1 passes through the rotating disk 3, the rotating cam 4, the unlocking gear 5, the first spring 6, the quick release disk 7 and the quick release plate 9 in sequence. The seat connection base 8 is installed on the upper end of the rotating shaft 101;

[0028] The first driving mechanism includes a pull rod 2, a rotating cam 4, an unlocking gear 5 and a first spring 6, and the first driving mechanism is used to lock and unlock the fixed plate 1 and the rotating plate 3. The rotating plate 3 after unlocking has two orientations: the child faces forward and the child faces backward. The second driving mechanism includes a quick release plate 7, a quick release plate 9 and a quick release switch 11, and the second driving mechanism is used to disassemble the seat.

[0029] See also Figure 2 The fixed disk 1 has a locking tooth 102 meshing with the unlocking gear 5. When the pull rod 2 is in the initial state, the unlocking gear 5 meshes with the locking tooth 102 of the fixed disk 1, and the fixed disk 1 is locked with the rotating disk 3;

[0030] The rotating disk 3 has a guide tooth 301, and the rotating cam 4 has an inclined groove 401 meshing with the guide tooth 301. The rotating cam 4 is sleeved on the gear of the unlocking gear 5. The flange bottom surface of the unlocking gear 5 abuts against the top surface of the rotating cam 4. The upward rotation of the rotating cam 4 can drive the unlocking gear 5 to move upward, so that the unlocking gear 5 is separated from the locking tooth 102 of the fixed disk 1.

[0031] The rotating disk 3 is provided with a guide groove, in which the pull rod 2 can slide. The pull rod 2 is connected to the rotating cam 4 through an unlocking wire rope 201. When the pull rod 2 slides along the guide groove, the unlocking wire rope 201 drives the rotating cam 4 to rotate.

[0032] In the initial state, the rotating cam 4 is located at the lower part of the rotating disk 3, which is the first state of the rotating cam 4. At this time, the inclined groove 401 of the rotating cam 4 is fully engaged with the guide tooth 301 of the rotating disk 3, and there is no pushing force on the unlocking gear 5; the pull rod 2 is pulled, and the unlocking wire rope 201 drives the rotating cam 4 to rotate. Under the cooperation of the inclined groove 401 and the guide tooth 301, the rotating cam 4 rotates and moves upward. The rotating cam 4 is partially engaged with the guide tooth 301 of the rotating disk 3, and the rotating cam 4 pushes the unlocking gear 5 to move upward, and the unlocking gear 5 disengages from the locking tooth 102 of the fixed disk 1. At the same time, the unlocking gear 5 compresses the first spring 6. At this time, the rotating cam 4 is located at the upper part of the rotating disk 3, which is the second state of the rotating cam 4.

[0033] See also Figure 2 and Figure 4 , the quick release plate 7 is arranged on the rotating plate 3, the rotating cam 4 and the unlocking gear 5 are located between the quick release plate 7 and the rotating plate 3, the first spring 6 is sleeved on the rotating shaft 101, and the lower end of the first spring 6 is arranged on the flange top surface of the unlocking gear 5, and the upper end of the first spring 6 is against the bottom surface of the quick release plate 7;

[0034] The quick release switch 11 is disposed on the rotating disk 3, and the quick release switch 11 can slide along the radial direction of the rotating disk 3. The quick release switch 11 includes a resisting column 1101, and the resisting column 1101 cooperates with the rear end of the quick release plate 9;

[0035] The quick release plate 9 is radially slidably arranged in the sliding groove of the quick release plate 7. The quick release plate 7 has a second spring. One end of the second spring is connected to the bottom of the sliding groove of the quick release plate 7. The other end of the second spring is against the front end of the quick release plate 9. The quick release plate 9 has a sliding groove. The sliding groove includes a small hole 901 and a large hole 902. The small hole 901 is located at the front of the sliding groove, and the large hole 902 is located at the rear of the sliding groove. There is an arc transition between the two to ensure that the rotating shaft 101 is not hindered when sliding. The upper end of the shaft 101 can slide forward and backward in the slide groove, and the upper end of the rotating shaft 101 cooperates with the small hole 901 and the large hole 902 respectively. An annular groove is opened at the end of the rotating shaft 101. The small hole 901 cooperates with the groove so that the quick release plate 9 clamps the rotating shaft 101, and the large hole 902 cooperates with the groove so that the quick release plate 9 and the rotating shaft 101 are loosened. The aperture of the small hole 901 is smaller than the diameter of the rotating shaft 101, and the aperture of the large hole 901 is larger than the diameter of the rotating shaft 101.

[0036] Working principle:

[0037] 1. Turning when the seat is not disassembled: the direction of the rotating disk 3 is changed by the first driving mechanism. The pull rod 2 is pulled to make the rotating cam 4 in the second state. At this time, the unlocking gear 5 is disengaged from the locking tooth 102 of the fixed disk 1, and the rotating disk 3 and the fixed disk 1 can rotate relative to each other. At this time, the direction of the seat is adjusted by rotating the rotating disk 3. After releasing the pull rod 2, the rotating cam 4 is reset to the first state under the action of the rebound force of the first spring 6. At this time, the unlocking gear 5 is engaged with the locking tooth 102 of the fixed disk 1, and the rotating disk 3 and the fixed disk 1 are locked and cannot rotate relative to each other.

[0038] 2. Disassembly of the seat: The disassembly of the seat is achieved through the second driving mechanism. First, the rotating disk 3 is disassembled as a whole together with the seat connecting base 8; in the initial state, under the action of the second spring, the small hole 901 of the quick-release plate 9 is clamped with the groove of the rotating shaft 101, which limits the relative movement of the rotating disk 3 and the fixed plate 1 in the vertical direction. At this time, the seat cannot be disassembled; when the seat needs to be disassembled, the quick-release switch 11 is slid, and the resistance column 1101 pushes the quick-release plate 9, and the large hole 902 of the quick-release plate 9 cooperates with the rotating shaft 101. Since the aperture of the large hole 902 is larger than the diameter of the rotating shaft 101, the rotating disk 3, the rotating cam 4, the unlocking gear 5, the first spring 6, the quick-release plate 7, the seat connecting base 8, the quick-release plate 9 and the quick-release switch 11 can be pulled upward as a whole, thereby completing the disassembly of the seat.

[0039] 3. Automatic locking when the seat is reinstalled: When the seat is reinstalled (the seat can be changed in direction), slide the quick-release switch 11, the large hole 902 of the quick-release plate 9 cooperates with the rotating shaft 101, and the rotating disk 3 and the rest of the body are placed downward into the fixed disk 1. At this time, under the rebound pressure of the first spring 6, the unlocking gear 5 presses the rotating cam 4, and the rotating cam 4 rotates downward until it is fully engaged with the guide tooth 301 of the rotating disk 3. At this time, the unlocking gear 5 is engaged with the locking tooth 102 of the fixed disk 1. After releasing the quick-release switch, under the action of the second spring, the small hole 901 of the quick-release plate 9 is clamped with the groove of the rotating shaft 101, and the rotating disk 3 and the fixed disk 1 are locked in the vertical direction.

[0040] In the above embodiments, the present invention is only exemplarily described, but those skilled in the art may make various modifications to the present invention without departing from the spirit and scope of the present invention after reading this patent application.
