Referring to fig. 1 to 5, the present application discloses a ceiling mount for mounting on a trolley, the ceiling mount comprising:

a rotation center 71 including a plurality of rotation disks 711 which are rotatably fitted;

a plurality of groups of frames 72, wherein the frames 72 belonging to the same group are connected with one rotating disc 711;

a plurality of prongs 73 are mounted to each frame 72 for connection to the frame of the cart.

The ceiling mount functions to form a support system for mounting subsequent coverings for creating a relatively isolated environment for the child. Avoid the influence of sun exposure and outside dirty environment. In order to provide a comfortable environment for children, the ceiling generally requires a large internal volume, and the ceiling needs to have a folding structure in order to be folded and stored conveniently. Compared with the common folding form of the conch-shaped concentric hinged layer-by-layer overlapped sleeves on the market, the technical scheme disclosed by the application has the advantages of small volume after folding and large internal space after unfolding

In a specific option, the rotary disks 711 are preferably two in number and are rotatably fitted to each other, which design enables a reduction in the volume of the rotation center 71 and a simplification of the structure, while two frames 72 are attached to each rotary disk 711. The two frames 72 are unfolded and folded by mutual rotation of the rotating discs 711. The number of rotating discs 711 and frames 72 can thus be adjusted as desired. For example, a plurality of rotating discs 711 are rotatably fitted to each other and a plurality of frames 72 are mounted on different rotating discs 711, which enables more complex space changes of the ceiling mount. When the rotating disks 711 are rotated with each other so that the interval between the frames 72 becomes large, the frames 72 form a three-dimensional space, and the ceiling brackets are unfolded; when the rotating disks 711 are rotated with each other so that the interval between the frames 72 becomes smaller, the three-dimensional space inside the frames 72 becomes smaller, and at this time, the ceiling brackets are unfolded. The roof support is mounted to the frame by prongs 73. In the actual selection, the ceiling support has two unfolding and folding modes, when the unfolding and folding of the frame and the unfolding and folding movement trends of the ceiling support are consistent, the ceiling support can be unfolded or folded together with the frame; when the unfolding and folding movement trends of the frame are inconsistent with the unfolding and folding movement trends of the ceiling support, the ceiling support can be assembled on the unfolded frame through the pins 73 after being unfolded, and can be detached and independently folded before the frame is folded. Is flexible and convenient.

The space in which the roof support is expanded and the volume in which it is collapsed is determined by the frame 72. In one embodiment, the number of frames 72 in each group of frames is one or more, and each frame 72 includes:

ceiling rods 721 connected to the respective rotating disks 711 and extending away from the rotation center 71;

a support rod 722 rotatably engaged with an end of the ceiling rod 721 remote from the rotation center 71, the support rod 722 having a pin 73 at its distal end;

all the ceiling rods 721 are radially distributed on the periphery of the rotation center 71 in the unfolded state of the ceiling support; in the collapsed state of the canopy support, all of the canopy rods 721 and support rods 722 are brought together.

In this embodiment, the two frames 72 are respectively connected to the rotating disc 711 and are located on the diameter and the extension line of the rotating disc 711. The frame 72 itself has two states of folding and unfolding, the frame 72 is in the unfolding state, and the ceiling rod 721 and the supporting rod 722 are mutually unfolded; when the frame 72 is in the folded state, the ceiling rods 721 and the supporting rods 722 are attached to each other, so that a larger space expression after being unfolded and a smaller folded volume after being folded are realized. In order to ensure the unfolding stability of the frame 72, in one embodiment, the ceiling rod 721 and the supporting rod 722 are matched through the limiting seat 7221, one of the ceiling rod 721 and the supporting rod 722 is used as a fixing part and fixedly connected with the limiting seat 7221, and the other is used as a rotating part and rotatably connected with the limiting seat 7221;

the stopper 7221 has a stopper 7222, and when the ceiling rod 721 and the support rod 722 are unfolded, the stopper 7222 abuts against the rotating member to restrict an angle between the ceiling rod 721 and the support rod 722.

When the frame 72 is unfolded, the unfolding angle of the ceiling rod 721 and the supporting rod 722 is limited by the limiting seat 7221, so that the unfolding stability is ensured, and the frame 72 can bear external force to ensure the structural integrity. But only the collapsing of the frame 72, the ceiling frame is still bulky after the turning discs 711 are turned over each other to collapse the ceiling frame, so that in one embodiment the turning discs 711 are axially stacked on each other, the outer circumference of each turning disc 711 is provided with coupling lugs 712, and each ceiling rod 721 in the frame 72 connected to the turning disc 711 is hinged to the corresponding coupling lug 712.

After the rotating discs 711 are stacked on each other in the axial direction, the rotational stroke between the rotating discs 711 can be limited by the engaging lugs 712, that is, the length of the engaging lugs 712 in the axial direction of the rotating discs 711 may be greater than the length of the rotating discs 711 in the axial direction, so that the engaging lugs 712 of different rotating discs 711 may be in an abutting state.

The rotational stroke between the rotating disks 711 can also be limited by the positional relationship between the frames 72. After the ceiling support is folded, the folded frames 72 are attached to each other, so that a smaller folding volume is realized, and the ceiling support is convenient to carry and store.

Since the ceiling mount has a plurality of foldable structures, the stability of the unfolded state is very important. In one embodiment, the prongs 73 are provided with a locking mechanism for engaging the frame of the cart and a guide mechanism.

The guide mechanism can provide limiting for the ceiling support except for the gravity direction, and the locking structure can provide connection strength, so that the ceiling support with a plurality of joints can also ensure the unfolding effect.

The present application also discloses a canopy, including a tarpaulin (not shown), mounted on each frame 72 as in the above-mentioned solutions, and deformed as the relative position of each frame 72 changes.

The tarpaulin can realize confined effect, provides good protection effect for passengers or article such as children.

The user can mount and dismount the ceiling mount through the driving part 743. In one embodiment, the driving part 743 includes:

a deformation strip 7431 formed by extending the socket 74 itself;

an operation section 7432 attached to one end of the deformation strip 7431;

the lock pin 742 is mounted on the deformation bar 7431, and after the pin 73 is connected with the socket 74, the deformation bar 7431 abuts against the pin 73, and the lock pin 742 is received in the lock hole 732.

The driving portion 743 functions to change the spatial position of the latch 742, thereby locking and unlocking the socket 74 and the pin 73. Compared with other design forms, the lock pin 742 is arranged on the deformation strip 7431, and the point is that the driving part 743 and the lock pin 742 are integrated, so that the volume of the driving part 743 can be reduced, transmission parts are saved, the whole driving part 743 can be more compact, and the ceiling bracket can be conveniently installed on various frame structures. Since the lock pin 742 and the lock hole 732 can only restrict the displacement of the socket 74 and the pin 73 in the plane,

therefore, in an embodiment, the pin 73 is provided with a first limiting groove 733 for receiving the socket 74, the cross section of the first limiting groove 733 is C-shaped, and two sides of the opening of the C-shape are clamped on the socket 74; one end of the first limiting groove 733 is closed to be a first limiting end 7331, and after the pin 73 is connected with the socket 74, the first limiting end 7331 abuts against the socket 74; the socket 74 is provided with a second limiting groove 744, the pin 73 is provided with a second limiting projection 734 matched with the second limiting groove 744, and after the pin 73 is connected with the socket 74, the second limiting projection 734 abuts against the second limiting groove 744.

The relative movement of the pin 73 and the socket 74 after the mating is limited on a plane by the limiting structure, so that the stability of the mating and the convenience of installation can be greatly improved.

The mounting and dismounting of the ceiling mount will be explained below in connection with specific components:

when a user needs to install the ceiling bracket, firstly, the frames 72 of the ceiling bracket are opened relative to the rotating center 71, the frames 72 are separated from each other by taking the connecting lugs 712 connected with the frames as rotating points until the frames are completely opened, and at the moment, a part of the frames 72 are abutted against the connecting lugs 712; then, the supporting rods 722 are opened, the supporting rods 722 of the frames 72 are far away from the ceiling rods 721 by using the limiting seats 7221 as rotating points, and after the supporting rods are unfolded in place, the space structure of the ceiling support is formed. In particular use, the pins 73 are mounted to the bottom of the support bar 722 (not shown) and the pins 73 are inserted into sockets 74 mounted on the frame. After the pin 73 and the socket 74 are inserted into each other, the lock pin 742 enters the lock hole 732 under the guidance of the first and second limiting grooves 733 and 744. The pin 73 and the socket 74 lock. The ceiling mount is installed in place.
