Description

Technical Field

[0001] The utility model relates to a manual trolley, in particular to an accessory or component specifically applicable to a baby carriage. Background Art

[0002] Baby carriages can provide convenience for the travel of infants and young children and are recognized by many families. The basic structure of a baby carriage includes a frame, wheels and a seat, and different functions can be designed at different positions.

[0003] The applicant proposed a seat backrest with a ventilation function in previous research. It realizes the ventilation function by setting a ventilation net on the seat pocket and sets an openable and closable storage board on the ventilation net to realize the dual functions of ventilation and storage. The technical problems existing in this structure are as follows:

[0004] Since the storage board is close to the ventilation net, the storage board only has the storage function after being opened. After the storage board is closed, it needs to be close to the ventilation net, and the storage area is severely compressed, resulting in the inability to continuously perform the storage function or the ventilation net cannot be effectively and fully closed. Summary of the Utility Model

[0005] The utility model provides a backrest ventilation structure, which specifically designs a ventilation storage area (storage area), so that there is still a considerable storage space after the ventilation function is closed. The main technical solutions adopted are as follows:

[0006] A backrest ventilation structure includes a backrest body, and the key points are that: the backrest body includes a back board and a surrounding board;

[0007] A circle of the surrounding board is provided on the back of the back board, the internal area of the surrounding board is a ventilation storage area, and ventilation holes communicating with the ventilation storage area are provided on the back board;

[0008] A cover board is provided on the back side of the back board, and the cover board covers the ventilation storage area;

[0009] The lower part of the cover board is hinged to the backrest body, and the cover board is configured to rotate to open or close the ventilation storage area;

[0010] The upper part of the cover board is connected to the backrest body through a locking mechanism, and the locking mechanism is configured to keep the cover board and the backrest body locked or unlocked.

[0011] The surrounding board is fixed to the back of the back board and extends towards the back side (rear) of the back board, which can increase the length of the ventilation storage area in the front-back direction, thereby expanding the space of the ventilation storage area. When the ventilation storage area is closed, the cover board and the backrest body are kept locked, and there can still be a relatively considerable storage space between them due to the extension of the surrounding board; at the same time, placing items in the storage space will not affect the full closing of the cover board.

[0020] Taking the state when the backrest body 1 is used vertically as the reference direction, the side facing the passenger is the relying surface (front), and the side facing away from the passenger is the back surface (rear). A circle of the surrounding board 12 is provided on the back surface of the backboard 11. The surrounding board 12 is fixedly connected to the backboard 11. The inner area of the surrounding board 12 is a ventilation storage area. Ventilation holes are provided on the backboard 11 and communicate with the ventilation storage area. The ventilation holes are preferably a group of mesh through holes;

[0021] A cover plate 2 is further provided on the back side of the backboard 11. The cover plate 2 covers the ventilation storage area. The cover plate 2 is away from the backboard 11. The cover plate 2 is close to the edge of the surrounding board 12 away from the backboard 11. The cover plate 2, the backboard 11 and the surrounding board 12 form a storage box.

[0022] The lower part of the cover plate 2 is hinged to the backrest body 1. The cover plate 2 is configured to rotate to open or close the ventilation storage area. Specifically: the lower part of the cover plate 2 near the edge is hinged to the backrest body 1; more specifically: the lower part of the cover plate 2 near the edge is hinged to the backboard 11; more specifically: a bottom hinge seat 6 is correspondingly provided on the backboard 11, and the lower part of the backboard 11 near the edge is hinged to the bottom hinge seat 6; the backboard 11 is larger than the surrounding board 12, and it is easier to maintain stability when the bottom hinge seat 6 is provided on the backboard 11.

[0023] The upper part of the cover plate 2 is connected to the backrest body 1 through a locking mechanism 3, and the locking mechanism 3 is configured to keep the cover plate 2 and the backrest body 1 locked or unlocked.

For example: The first structure: The locking mechanism 3 includes two magnetic attraction blocks, and the two magnetic attraction blocks are respectively arranged on the cover plate 2 and the backrest body 1. The second structure: The locking mechanism 3 is a magic tape. The third structure: The locking mechanism 3 is a bolt assembly. In addition, mature structures such as the locking and unlocking assembly of an automotive glove box and a press-type elastic self-locking mechanism can all be used as the locking mechanism 3 of the present application. The structures and installation methods of these locking mechanisms 3 are well known to those skilled in the art and will not be elaborated here.

[0025] According to the usage habit, the ventilation holes and the surrounding plate 12 are both located in the upper part of the back plate 11.

[0026] An angle limiting mechanism 4 is also arranged between the cover plate 2 and the backrest body 1, and the angle limiting mechanism 4 is configured to limit the rotation angle of the cover plate 2.

[0027] There are also various specific structures of the angle limiting mechanism 4, such as connecting rods, ropes, etc. In this specific embodiment, the angle limiting mechanism 4 includes two hinged connecting rods. An upper hinge seat 7 is fixedly arranged on the surrounding plate 12. The free end of the first connecting rod is hinged to the upper hinge seat 7, and the free end of the first connecting rod is hinged to the cover plate 2.
