[0031] The following embodiments illustrate the present invention, but the present invention is not limited to these embodiments. Modifications to the specific implementation of the present invention or equivalent substitutions for some technical features, without departing from the spirit of the present invention, should all be covered within the scope of the technical solution claimed by the present invention.

[0032] like Figure 1-15A base structure 1 with anti-reverse installation capability includes a base structure 1 and a placement structure. The placement structure is installed on the base structure 1. The base structure 1 includes a chassis 11 and a rotating assembly 12. A pressure block assembly 3 is provided on the rotating assembly 12. The pressure block assembly 3 is installed on the rotating assembly 12 and can move up and down. When the placement structure is installed on the base structure 1, the pressure block assembly 3 is driven to move downward. An installation groove 111 is provided on the chassis 11, and a stop surface 112 is formed on the chassis 11, and on the side of the chassis 11 near the rear end. The installation groove 111 is used to cooperate with the downwardly moving pressure block assembly 3 to install the placement structure on the base structure 1. The stop surface 112 is used to prevent the pressure block assembly 3 from moving downward to limit the installation of the placement structure on the base structure 1.

[0033] This utility model proposes a base structure 1 that prevents reverse installation. The placement structure is placed on the base structure 1, and the pressure block assembly 3 moves downward at the rotating assembly 12. When the placement structure is correctly positioned on the base structure 1, the pressure block assembly 3 moves downward and extends into the mounting groove 111, thus the placement structure is installed on the base structure 1. When the placement structure is incorrectly positioned on the base structure 1, the pressure block assembly 3 will touch the stop surface 112 when it moves downward. The stop surface 112 will restrict the downward movement of the pressure block assembly 3, preventing the placement structure from being placed on the base structure 1, thereby causing a safety accident.

[0034] This invention proposes a base structure 1 that prevents reverse installation. When the placement structure is correctly oriented, it is installed by the downward movement of the pressure block assembly 3, which engages with the mounting groove 111 of the base 11. When the placement structure is incorrectly oriented, the downward movement of the pressure block assembly 3 is restricted by the stop surface 112, preventing the placement structure from being placed on the base structure. This ensures that the placement structure is installed in the correct orientation when mounted on the base, avoiding incorrect installation or reverse installation, which could lead to safety accidents.

[0035] In this embodiment, the placement structure includes a baby carrier and a seat for a child safety seat.

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

[0037] When the placement structure and base structure are installed together correctly, the protrusion at the placement structure will press against the pressure block assembly, causing the pressure block assembly to move downwards, allowing the placement structure to be installed onto the base structure. However, if the placement structure and base are installed incorrectly, the protrusion at the bottom of the placement structure will press against the pressure block assembly, but since the pressure block assembly cannot move downwards, the pressure block assembly and protrusion will collide, preventing the placement structure from being installed onto the base structure. This method ensures correct installation orientation during the placement and installation process, avoiding the need for reinstallation after installation is complete, saving time and effort.

[0038] When a child safety seat or infant carrier is installed in a car, because the child is young, the seat or carrier needs to be installed facing the back of the car seat. This utility model proposes a base structure that can prevent reverse installation. Because the placement structure and the base structure are detachably connected, after the base structure is installed on the car seat, the placement structure is installed on the base structure with the correct orientation.

[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 is in contact with 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 face of the driving block 31 faces the placement structure, the lower end face of the driving block 31 faces the pressing block 32, and the lower end face of the driving block 31 is in contact with the pressing block 32.

[0041] The rotating assembly 12 includes a bottom cover body 121 and a turntable 122. The turntable 122 is connected to the bottom cover body 121, and the turntable 122 is located at one end near the chassis 11, while the bottom cover body 121 is located at the other end away from the chassis 11. The pressing block 32 is disposed at the turntable 122 and can move up and down at the turntable 122. The driving block 31 is disposed at the bottom cover body 121 and can move up and down at the bottom cover body 121.

[0042] In this embodiment, the bottom cover body 121 and the turntable 122 are fixedly connected together.

[0043] In this embodiment, a connecting part 120 is provided on the bottom cover body 121, and the connecting part 120 is used to connect with the placement structure.

[0044] In some embodiments, the connecting portion 120 is a snap-fit.

[0045] A pressure block seat 42 is provided at the turntable 122, and the pressure block 32 is installed at the pressure block seat 42 in a way that can move up and down; a drive block seat 41 is provided at the bottom cover body 121, and the drive block 31 is installed at the drive block 31 in a way that can move up and down.

[0046] A first return spring is provided at the pressure block seat 42. One end of the first return spring is in contact with the pressure block seat 42, and the other end is in contact with the pressure block 32. The first return spring is used to drive the pressure block 32 to move upward.

[0047] A through hole 321 is formed on the pressure block 32, and a limiting post 422 extends from the pressure block seat 42 toward the through hole. The limiting post 422 passes through the through hole 321, and the cooperation between the limiting post 422 and the through hole 321 can limit the distance the pressure block 32 can move downward and upward.

[0048] The lower end of the first reset spring 51 is in contact with the limiting post 422, and the upper end of the first reset spring 51 is in contact with the top end of the through hole 321, which can drive the pressure block 32 to move upward. That is, when the pressure block 32 moves downward, it drives the pressure block 32 to move upward and reset.

[0049] A second return spring 52 is provided at the drive block seat 41. One end of the second return spring 52 contacts the drive block seat 41, and the other end contacts the drive block 31. The second return spring 52 is used to drive the drive block 31 to move upward. In this embodiment, a mounting cavity is formed at the drive block seat 41, and a protrusion 311 extends from the drive block 31 toward the mounting cavity. One end of the second return spring 52 contacts the protrusion 311, and the other end contacts the bottom of the mounting cavity to drive the drive block 31 to move upward. That is, when the drive block 31 moves downward, under the action of the second return spring, the drive block 31 is driven to move upward to reset.

[0050] The turntable 122 is rotatably mounted on the chassis 11, and the groove wall 110 of the mounting groove 111 abuts against the pressure block 32 to restrict the rotation of the turntable 122. The rotation angle of the turntable 122 can be restricted by the groove wall of the mounting groove 111.

[0051] The mounting groove 111 is arc-shaped, and the arc angle of the mounting groove 111 is 180°-270°.

[0052] The baffle 112 is arc-shaped, and the arc angle of the mounting groove 111 is 90-180°.

[0053] The mounting groove 111 and the stop surface 112 are both located on one end face of the chassis 11 facing the rotating assembly 12.

[0054] In this embodiment, the arc shape of the mounting groove 111 and the stop surface 112 can be closed to form a complete ring. That is, the arc radius of the mounting groove 111 is the same as the arc radius of the stop surface 112.

[0055] The above preferred embodiments should be regarded as illustrative examples of the embodiments of the present application. Any technical deductions, substitutions, improvements, etc. that are similar to or based on the present application should be considered within the scope of protection of this patent.
