[0031] To make the objectives, features, and advantages of this invention more apparent and understandable, the technical solutions of the embodiments of this invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the embodiments described below are only some embodiments of this invention, and not all embodiments. Based on the embodiments of this invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this invention.

[0032] The technical solution of the present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0033] Please see Figures 1-6 As shown, the present invention designs a rotatable stroller, which includes a handle 1, a seat assembly 3, and a base 11. The handle 1 is provided with an abutment block 2, the seat assembly 3 is provided with a first push rod 5, and a first locking member 4 and a first unlocking member 17 are provided between the handle 1 and the seat assembly 3. The first unlocking member 17 abuts against the first locking member 4, and a second locking member 10 is provided between the seat assembly 3 and the base 11. The abutment block 2 abuts against the first push rod 5, and the first push rod 5 abuts against the second locking member 10. In the first state, the first unlocking member 17 is driven, and the first unlocking member 17 pushes the first locking member 4 to disengage from the seat assembly 3. The handle 1 rotates relative to the seat assembly 3 under force. The abutment block 2 pushes the first push rod 5, and the first push rod 5 pushes the second locking member 10, which disengages from the base 11. The seat assembly 3 rotates relative to the base 11 under force to switch to the second state.

[0034] It should be noted that the first locking member 4 of the present invention is located between the handle 1 and the seat assembly 3, the second locking member 10 is located between the seat assembly 3 and the base 11, and the first unlocking member 17 is located between the handle 1 and the seat assembly 3. The inclined surface of the first push rod 5 abuts against the inclined surface of the second locking member 10. When the seat assembly 3 needs to be rotated, the first unlocking member 17 is driven. After the first unlocking member 17 pushes the first locking member 4 completely into the handle 1, the handle 1 and the seat assembly 3 are unlocked. At this time, the handle 1 is under force and can rotate relative to the seat assembly 3. When the handle 1 and the seat assembly 3 are in a vertical state, the abutment block 2 on the handle 1 can push the first push rod 5. The first push rod 5 moves in the direction close to the second locking member 10 and pushes the second locking member 10 away from the base 11. The seat assembly 3 and the base 11 are unlocked. At this time, the seat assembly 3 is under force and can rotate relative to the base 11. Compared with the prior art, when rotating the seat assembly 3, the present invention does not need to move to the front of the stroller, which brings great convenience to people.

[0035] Specifically, the rotatable stroller also includes a front wheel assembly 14 and a rear wheel assembly 15, both of which are connected to a base 11.

[0036] Specifically, the seat plate assembly 3 also includes a second push rod 6. In the first state, when the abutting block 2 abuts against the first push rod 5, the side wall of the second push rod 6 abuts against the abutting block 2.

[0037] Specifically, the seat plate assembly 3 also includes a first push block 8, which abuts against the second push rod 6 and the base 11.

[0038] Specifically, the seat plate assembly 3 also includes a third push rod 7 and a second push block 9. The base 11 is provided with a limiting groove 12. In the first state, one end of the second push block 9 is located in the limiting groove 12, and the inclined surface of the second push block 9 abuts against the inclined surface of the limiting groove 12. The third push rod 7 and the second push rod 6 are respectively located on both sides of the first push rod 5, and the second push block 9 abuts against the third push rod 7.

[0039] Specifically, in the second state, one end of the first push block 8 is confined within the limiting groove 12, the second push rod 6 cancels its contact with the abutment block 2, and the side wall of the third push rod 7 abuts against the abutment block 2. When the seat plate assembly 3 and the base 11 are in the first state, the gap between the end of the third push rod 7 and the handle 1 is larger than the size of the abutment block 2, and the gap between the end of the second push rod 6 and the handle 1 is smaller than the size of the abutment block 2. When the handle 1 rotates, the abutment block 2 can smoothly pass through the third push rod 7. Continuing to rotate until the handle 1 and the seat plate assembly 3 are at a 90-degree angle, the abutment block 2 can abut against the first push rod 5. The first push rod 5 can disengage the second locking member 10 from the base 11, and the side wall of the second push rod 6 abuts against the abutment block 2, preventing the handle 1 from continuing to rotate. As the rotation continues, the second push block 9 disengages from the limiting groove 12 after the rotating seat plate assembly 3 rotates. The side wall of the third push rod 7 abuts against the abutting block 2. Under the constraint of the second push rod 6 and the third push rod 7, the handle 1 cannot rotate. When the seat plate assembly 3 rotates 180 degrees, it is in the second state. The first push block 8 is limited to the limiting groove 12. The second push rod 6 cancels the constraint on the abutting block 2. The third push rod 7 still abuts against the abutting block 2. The handle 1 can rotate towards the rear wheel assembly 15, but cannot rotate towards the front wheel.

[0040] Specifically, the rotatable stroller also includes a third locking member 16, a third unlocking member 18, and a fixing part 13. The front wheel assembly 14 and the rear wheel assembly 15 are both connected to the fixing part 13. The third locking member 16 is located between the fixing part 13 and the base 11 and is used to lock the fixing part 13 and the base 11. The third unlocking member 18 abuts against the third locking member 16.

[0041] Specifically, the rotatable stroller also includes a first link and a second link, with the first link connecting to the front wheel assembly 14 and the second link connecting to the rear wheel assembly 15.

[0042] Specifically, the rotatable stroller also includes a first elastic element, which connects a third locking element 16 and a fixing part 13.

[0043] When the third unlocking member 18 of the present invention is driven, it can push the third locking member 16 away from the base 11. At this time, the base 11 is subjected to force and can flip up and down relative to the fixed part 13. When the first link and the second link are subjected to force, the front wheel assembly 14 and the rear wheel assembly 15 can move closer to each other. The base 11, the front wheel assembly 14 and the rear wheel assembly 15 can be folded. The third unlocking member 18 is not driven. The first elastic member provides the third locking member 16 with an elastic force that abuts against the third unlocking member 18. The fixed part 13 locks the base 11, and the base 11 is locked and cannot flip up and down.

[0044] Specifically, the rotatable stroller also includes a second elastic member and a third elastic member. The handle 1 is provided with a first receiving groove, the seat assembly 3 is provided with a second receiving groove, the second elastic member connects the first receiving groove and the first locking member 4, the base 11 is provided with a third receiving groove, the seat assembly 3 is provided with a fourth receiving groove, and the third elastic member connects the fourth receiving groove and the second locking member 10.

[0045] It should be noted that the first locking member 4 of the present invention is a gear, and the second elastic member is disposed between the first receiving groove and the first locking member 4. In the locked state, the second elastic member constantly provides elastic force to the gear in both the first and second receiving grooves, and the third elastic member constantly provides elastic force to the second locking member 10 in both the third and fourth receiving grooves. When the first unlocking member 17 is driven, it can push the first locking member 4 to move towards the direction closer to the first receiving groove. After the first locking member 4 has moved completely into the first receiving groove, the handle 1 can rotate relative to the seat plate assembly 3 under force. When the handle 1 is rotated to a 90-degree angle with the seat plate assembly 3, the abutment block 2 can push the second locking member 10, and the second locking member 10 moves towards the direction closer to the fourth receiving groove. After the second locking member 10 has moved completely into the fourth receiving groove, the seat plate assembly 3 and the base 11 are unlocked, and the seat plate assembly 3 can rotate relative to the base 11 under force.

[0046] Specifically, the rotatable stroller also includes a brake and a pedal 19. The brake is connected to the rear wheel assembly 15 and is used to limit the rotation of the rear wheel assembly 15. The pedal 19 is connected to the front wheel assembly 14, and the seat assembly 3 has an opening at one end near the pedal 19. When the brake of the present invention is pressed, the stroller cannot be pushed forward, which enhances the safety performance of the stroller. The pedal 19 facilitates the support of the baby's legs, which enhances its practicality.
