A stroller frame with a hidable release actuator includes a foldable frame, a locking mechanism, a release mechanism and a baby carrier. The locking mechanism is mounted on the foldable frame for locking the foldable frame in the erected configuration. The release mechanism has a release actuator operatively mounted on the foldable frame for unlocking the locking mechanism by rotation in either a forward direction or a rearward direction. The baby carrier has a deployed position to support a baby occupant thereon and can hide the release actuator thereunder. The baby carrier can be converted into a folded position to permit the access to the release actuator. By this arrangement, to prevent the caregiver from accessing the release actuator, so as to avoid accidentally folding of the foldable frame before the baby occupant being held up from the baby carrier.

1. A stroller frame, including: a foldable frame (10), having an erected configuration (100) and a folded configuration (200);a locking mechanism (3), mounted on the foldable frame (10) for locking the foldable frame in the erected configuration (100);a release mechanism (4), having a release actuator (43) operatively mounted on the foldable frame (10) for unlocking the locking mechanism (3) by rotation in either a forward direction (45) or a rearward direction (46); anda baby carrier (2), having a deployed position (26) for supporting a baby occupant thereon and hiding the release actuator (43) thereunder and thereby blocking access to the release actuator (43) and preventing the locking mechanism (3) from unlocking, and a folded position (27) for permitting access to the release actuator (43);wherein the baby carrier (2) includes:a connector (23), for releasably connecting the baby carrier (2) to the foldable frame (10);a seat frame 1241 connected to the connector (23) for support a baby occupant thereon; anda backrest frame (25), pivotally connected to the seat frame (24) and capable of converting the baby carrier (2) into the deployed position (26) and the folded position (27) by rotation; wherein the backrest frame (25) is lockable into the deployed position (26), and wherein the backrest frame (25) is configured to support the back of the baby occupant and shields the release actuator (43) when the backrest frame (25) is locked in the deployed position (26);wherein the foldable frame (10) includes:a front strut (11), having a pair of front wheels (12) pivoted at a front-lower end, and two joints (13) mounted on a rear-upper end thereof;a rear strut (15), having a pair of rear wheels (16) pivotally connected at a rear-lower end, and a front upper end pivotally connected to the joints (13);a pair of push arms (17), slidably passing through the two joints (13) respectively and lockable by the locking mechanism (3) in a locked position; anda linking element (18), pivotably connected between a lower end of the push arms (17) and the rear strut (15). 2. The stroller frame according to claim 1, wherein the foldable frame (10) is equipped with a pair of sockets (14) for releasably connecting the baby carrier (2) to the foldable frame (10). 3. The stroller frame according to claim 2, wherein the baby carrier (2) is selectable to connect to the foldable frame (10) either in a forward direction (21) or in a rearward direction (22). 4. The stroller frame according to claim 1, wherein the backrest frame (25) is equipped with an unlocking mechanism (28) for unlocking the backrest frame (25) from the deployed position (26). 5. The stroller frame according to claim 1, wherein the push arms (17) are lockable to the rear strut (15) by the locking mechanism (3). 6. The stroller frame according to claim 1, wherein the rear strut (15) has two sides each formed with a first positioning portion (31), and the locking mechanism (3) includes: two first latch elements (32), retractably mounted within the push arms (17) respectively;two resilient elements (30), biasing the two first latch elements (32) toward the first positioning portion (31) thereby locking the push arms (17) to the rear strut (15). 7. The stroller frame according to claim 6, wherein the front strut (11) has two sides each, is formed with a second positioning portion (33) at the upper end thereof, and the locking mechanism (3) includes two second latch elements (34) for engaging with the second positioning portions (33), respectively so as to lock the push arms (17) to the front strut (11). 8. The stroller frame according to claim 7, wherein the release mechanism (4) has two sides, each of which includes: a sliding element (42), movably received in one of the push arms (17) and being formed with two skewed slots for driving one of the first latch elements (32) and one of the second latch elements (34) so as to withdraw said first latch element (32) from the first positioning portion (31), and withdraw said second latch element (34) from the second positioning portion (33); anda sleeve (41) operatively sleeved on the push arms (17) and associating between the sliding element (42) and the release actuator (43); wherein the sleeve (41) is driven by the release actuator (43) to move downward thereby driving the sliding element (42) to unlock the push arms (17) from the rear strut (15). 9. The stroller frame according to claim 8, wherein the release actuator (43) has two ends pivotally connected on the joints (13), and each of the ends of the release actuator (43) being formed with a cam-like extension (49) slidably abutted against the sleeve (41), so as to drive the sleeve (41) to move downward by rotation of the release actuator (43). 10. The stroller frame according to claim 9, wherein the sleeve (41) is formed with a side extension (44) for slidably abutting against the cam-like extension (49). 11. The stroller frame according to claim 8, wherein the release actuator (43) is formed with a gripped portion (48) for either pushing or pulling by hand to rotate the release actuator (43). 12. The stroller frame according to claim 6, wherein the release mechanism (4) includes: a sliding element (42), movably received in the push arms (17) for driving the first latch elements (32) to withdraw from the first positioning portion (31) thereby unlocking the push arms (17) from the rear strut (15);a sleeve (41) operatively sleeved on the push arms (17) and associating between the sliding element (42) and the release actuator (43); wherein the sleeve (41) is driven by the release actuator (43) to move downward thereby driving the sliding element (42) to unlock the push arms (17) from the rear strut (15). 13.
