[0031] The following examples illustrate the present invention, but the present invention is not limited to these examples. Modifications to the specific embodiments of the present invention or equivalent replacement of some technical features without departing from the spirit of the present invention should be included in the scope of the technical solution claimed by the present invention.

[0032] like Figure 1-15A base structure 1 capable of preventing reverse installation comprises a base structure 1 and a placement structure, wherein the placement structure is installed on the base structure 1, the base structure 1 comprises a chassis 11 and a rotating assembly 12, a pressing block assembly 3 is provided on the rotating assembly 12, the pressing block assembly 3 is installed on the rotating assembly 12 so as to be movable up and down, and when the placement structure is installed on the base structure 1, the pressing block assembly 3 is driven to move downward, a mounting groove 111 is provided on the chassis 11 and on a side of the chassis 11 close to the front end, a blocking surface 112 is formed on the chassis 11 and on a side of the chassis 11 close to the rear end, the mounting groove 111 is used to cooperate with the downwardly moving pressing block assembly 3 to install the placement structure on the base structure 1, and the blocking surface 112 is used to block the downward movement of the pressing block assembly 3 to limit the placement structure from being installed on the base structure 1.

[0033] The present invention proposes a base structure 1 that can prevent reverse installation, wherein the placement structure is placed on the base structure 1, and the pressing block assembly 3 moves downward at the rotating assembly 12. When the placement structure is placed on the base structure 1 in a correct direction, the pressing block assembly 3 moves downward and extends into the installation groove 111, and the placement structure is installed on the base structure 1; when the placement structure is placed on the base structure 1 in an incorrect direction, the pressing block assembly 3 touches a blocking surface 112 when moving downward, and the blocking surface 112 limits the downward movement of the pressing block assembly 3. The pressing block assembly cannot move downward, so that the placement structure cannot be placed on the base structure 1, thereby causing a safety accident.

[0034] The present invention proposes a base structure 1 that can prevent reverse installation. When the placement structure is placed in the correct direction, the pressing block assembly 3 moves downward to match the installation groove 111 of the chassis 11 for installation; when the placement structure is placed in an incorrect direction, the pressing block assembly 3 is limited to move downward by the blocking surface 112, so that the placement structure cannot be placed on the base structure. It is ensured that when the placement structure is installed on the base, its installation direction is correct, avoiding the situation where the placement structure is installed in the wrong direction or the placement structure is reversed, thereby preventing safety accidents.

[0035] In this embodiment, the placement structure includes a carrier and a seat body of a safety seat.

[0036] In this embodiment, a protrusion is formed at the bottom of the placement structure.

[0037] When the placement structure is installed in coordination with the base structure and the installation direction is correct, the protrusion at the placement structure will press the pressing block assembly, causing the pressing block assembly to move downward, and the placement structure can be installed on the base structure; when the placement structure is installed in coordination with the base but the installation direction is wrong, the protrusion at the bottom of the placement structure presses the pressing block assembly, but because the pressing block assembly cannot move downward, the pressing block assembly conflicts with the protrusion, making it impossible for the placement structure to be installed on the base structure. The correct installation direction can be ensured during the placement and installation of the placement structure, avoiding the situation where the installation error is discovered only after the installation is completed and the need to reinstall occurs, saving installation time and energy.

[0038] When a safety seat or a carrier is installed on a car, since the infant is very young, the seat or carrier needs to be installed facing the car seat backrest. The present invention proposes a base structure that can prevent reverse installation. Since the placement structure and the base structure are detachably connected, the placement structure can be installed on the base structure with the correct direction after the base structure is installed on the car seat.

[0039] The pressing block assembly 3 includes a pressing block 32 and a driving block 31. The driving block 31 is above the pressing block 32. One end of the driving block 31 faces the placement structure, and the other end contacts the pressing block 32. The driving block 31 is used to contact the placement structure and drive the pressing block 32 to move downward.

[0040] In this embodiment, the upper end surface of the driving block 31 faces the placement structure, the lower end surface of the driving block 31 faces the pressing block 32 , and the lower end surface of the driving block 31 contacts the pressing block 32 .
