[0055] While this invention has been illustrated and described with reference to specific embodiments, it should not be limited to the details shown. Rather, various modifications to these details may be made within the scope of equivalents of the claims and without departing from the invention.

[0056] The descriptions of directions such as "front," "back," "up," and "down" used in this article are for ease of understanding only. This invention is not limited to these directions, but can be adjusted according to actual circumstances.

[0057] First refer to Figures 1 to 7 The general description of the carrier 200 (e.g., a crib) and the canopy applied to the carrier 200 according to this application. As shown, the carrier 200 has a frame 210, the bottom and sides of which are covered with a drape 230 ( Figures 13 to 15 This is for carrying an infant. In this embodiment, the frame 210 is foldable or collapsible; however, in other embodiments, the frame 210 may be fixed. In this embodiment, the frame 210 is hexagonal; however, in other embodiments, the frame 210 may have different shapes, such as rectangular or circular.

[0058] A connector 220 is provided at the upper part of the frame 210. The connector 220 can be a zigzag-shaped component that bends along the upper edge of the frame 210, or it can be an arc-shaped, straight, or other shaped component. In this embodiment, the connectors 220 are provided at each corner of the frame 210, that is, six connectors 220 are evenly distributed along the upper edge of the frame 210. However, in other embodiments, the number of connectors 220 can be more or less, for example, two, four, or eight connectors 220.

[0059] The ceiling connection device 100 can be detachably inserted into the carrier 200, and more specifically, into the insertion portion 220 of the carrier 200. The ceiling connection device 100 can be inserted into any insertion portion 220. In this embodiment, two ceiling connection devices 100 are symmetrically inserted into two opposite insertion portions 220.

[0060] The first canopy rod 300 and the second canopy rod 400 are rotatably connected to the canopy coupling device 100, with the rotation axis X approximately a straight line connecting the two canopy coupling devices 100. Tarpaulin 500 ( Figures 13 to 15 The two ends of the canopy rod are respectively connected to the first canopy rod 300 and the second canopy rod 400. Through the canopy coupling device 100 of this application, the first canopy rod 300 and the second canopy rod 400 rotate independently. When the first canopy rod 300 and the second canopy rod 400 rotate to the sides so that the carrier 200 is close to a horizontal position ( Figure 6 The tarpaulin 500 is fully deployed, forming a complete sunshade. When one of the first canopy pole 300 and the second canopy pole 400 rotates to the upper part of the vehicle 200, and the other rotates to a certain angle with the upper part of the vehicle 200 ( Figures 1 to 5 , Figure 7 The tarpaulin 500 is partially unfolded to form a partial sunshade. When the first roof pole 300 and the second roof pole 400 are rotated to overlap each other and be close to horizontal (not shown), the tarpaulin 500 is fully folded, so that the sunshade is fully closed.

[0061] Now refer to Figures 8 to 12 The ceiling engagement device 100 according to this application is described in detail. As shown in the figure, the ceiling engagement device 100 includes a socket 110, a first rotating seat 120, a second rotating seat 130, and a locking member 140. The ceiling engagement device 100 may also include an elastic member 150.

[0062] A socket 110 is used to connect the ceiling connection device 100 to the carrier 200. The socket 110 has a base end 112 and an engagement end 111. The base end 112 is rotatably connected to a first rotating seat 120 and a second rotating seat 130, and the engagement end 111 engages with the carrier 200. The shape of the engagement end 111 corresponds to the shape of the insertion portion 220 on the carrier 200. More specifically, the engagement end 111 may be shaped like a clamp fitted over the outside of the insertion portion 220, and the lower end of the engagement end 111 may have an inwardly protruding engaging portion 115. When the engagement end 111 is fitted onto the insertion portion 220, the engaging portion 115 engages with the lower edge of the insertion portion 220 to secure the ceiling connection device 100 to the carrier 200. The base end 112 is disc-shaped, and the center of this disc defines a rotation axis X. In this embodiment, the rotation axis X is approximately perpendicular to the line connecting the joint end 111 and the base end 112. That is, the line connecting the joint end 111 and the base end 112 extends approximately vertically, while the rotation axis X extends approximately horizontally.

[0063] One side of the base end 112 faces the interior of the vehicle 200, hereinafter referred to as the inner side, and the other side of the base end 112 faces the exterior of the vehicle 200, hereinafter referred to as the outer side.

[0064] The inner side of the base end 112 is provided with a first positioning recess 113, which is in the form of a fan-shaped recess centered on the rotation axis X. Multiple first positioning recesses 113 are provided along the circumferential direction. The first positioning recesses 113 are used to accommodate and engage the first positioning protrusion 123 on the first rotating seat 120 (e.g., ...). Figure 10 , Figure 11 (as best shown), so as to fix the relative angle between the first rotating seat 120 and the base end 112. In other embodiments, the base end 112 may be provided with a first positioning protrusion 123 instead of a first positioning recess 113, and correspondingly, the first rotating seat 120 is provided with a first positioning recess 113 instead of a first positioning protrusion 123.

[0065] A first rotation limiting portion 114 is provided at a circumferential position of the socket 110. In this embodiment, the first rotation limiting portion 114 is configured as a sheet-like portion extending inward along the axial direction from the circumferential edge of the socket 110. In other embodiments, the first rotation limiting portion 114 may be configured as a rod or other suitable shape. The first rotation limiting portion 114 is used to limit the range of the relative rotation angle between the socket 110 and the first rotating seat 120, which will be described in detail below.

[0066] The first rotating seat 120, the second rotating seat 130, and the locking member 140 are respectively stacked and connected to the base end 112 of the socket 110, and are rotatable relative to the socket 110 around the same rotation axis X. The first rotating seat 120 is stacked between the base end 112 and the second rotating seat 130, and the first top rod 300 and the second top rod 400 are respectively inserted into the first rotating seat 120 and the second rotating seat 130 along a direction perpendicular to the rotation axis X. More specifically, in the direction of the rotation axis X, from the outside to the inside, the components are, in sequence, the socket 110, the first rotating seat 120, the locking member 140, and the second rotating seat 130. The rotation shaft 160 passes through the center of each of the above components in sequence, so that these components can be rotatably assembled together.

[0067] The first rotating seat 120 has a first disc-shaped portion 121 and a first top rod joint portion 122. The center of the first disc-shaped portion 121 is located at the rotation axis X, and the first top rod joint portion 122 extends outward from the outer periphery of the first disc-shaped portion 121 in a direction perpendicular to the rotation axis X. One end of the first top rod 300 is inserted into the first top rod joint portion 122, such that the rotation of the first disc-shaped portion 121 around the rotation axis X drives the first top rod 300 to rotate around the rotation axis X. A first positioning protrusion 123 is provided on the side of the first disc-shaped portion 121 facing the socket 110 (i.e., the outer side), rising towards the socket 110. The shape and position of the first positioning protrusion 123 correspond to the position of the first positioning recess 113, and in this embodiment, it is a fan shape centered on the rotation axis X. In this embodiment, a pair of first positioning protrusions 123 are provided symmetrically along the rotation axis X; however, in other embodiments, there may be only one first positioning protrusion 123, or there may be more first positioning protrusions 123. As mentioned above, the first positioning protrusion 123 on the first rotating seat 120 and the first positioning recess 113 on the socket 110 can be interchanged.

[0068] A first locking portion 124 is provided at a corresponding circumferential position of the first rotating base 120, and the first rotation limiting portion 114 interacts with the first locking portion 124. In one embodiment, the first locking portion 124 is provided circumferentially along the first rotating base 120, such that the first rotating base 120 is limited to rotating relative to the socket 110 between a first angular position and a second angular position. When viewed from the socket 110 side, if the engaging end 111 of the socket 110 is located at the 6 o'clock position on a clock face, the first angular position is approximately the 3 o'clock position, and the second angular position is approximately the 11 o'clock position.

[0069] The locking member 140 is inserted between the first rotating seat 120 and the second rotating seat 130, and can rotate together with the first rotating seat 120 to limit the relative angle between the first rotating seat 120 and the second rotating seat 130 to change within a certain range. In this embodiment, the locking member 140 is placed in the hollow cylindrical space of the first rotating seat 120.

[0070] In this embodiment, the inner wall of the first rotating seat 120 is provided with a protruding insert 125, and the outer wall of the locking member 140 is provided with a recessed slot 143. Through the engagement between the slot 143 and the insert 125, the locking member 140 is inserted into the first rotating seat 120 in a manner without relative rotation. In other embodiments, the insert 125 of the first rotating seat 120 and the slot 143 of the locking member 140 can be interchanged, that is, the inner wall of the first rotating seat 120 is provided with a recessed slot 143, while the outer wall of the locking member 140 is provided with a protruding insert 125. The locking member 140 is slidably inserted into the first rotating seat 120 so that the first rotating seat 120 and the slider respectively abut outward against the socket 110 and inward against the second rotating seat 130.

[0071] In this embodiment, the locking member 140 is disc-shaped, and a second positioning protrusion 142 is provided on the side facing the second rotating seat 130 (e.g., Figure 10 , Figure 11 (As best shown), it is inserted into the second positioning recess 133 of the second rotating seat 130 to fix the relative angle between the locking member 140 and the second rotating seat 130. In other embodiments, the locking member 140 may have a second positioning recess 133 instead of a second positioning protrusion 142, and correspondingly, the second rotating seat 130 may have a second positioning protrusion 142 instead of a second positioning recess 133. The shape of the second positioning protrusion 142 is similar to that of the first positioning protrusion 123, and will not be described again here.

[0072] The second rotating seat 130 has a second disc-shaped portion 131 and a second top rod joint portion 132. The center of the second disc-shaped portion 131 is located at the rotation axis X, and the second top rod joint portion 132 extends outward from the outer periphery of the second disc-shaped portion 131 in a direction perpendicular to the rotation axis X. One end of the second top rod 400 is inserted into the second top rod joint portion 132, such that the rotation of the second disc-shaped portion 131 around the rotation axis X drives the second top rod 400 to rotate around the rotation axis X. A recessed second positioning recess 133 is provided on the side (i.e., the inner side) of the second disc-shaped portion 131 facing the locking member 140. The shape and position of the second positioning recess 133 correspond to the second positioning protrusion 142. The shape of the second positioning recess 133 is similar to that of the first positioning recess 113, and will not be described again here.

[0073] A second locking portion 134 is provided at a circumferential position of the second rotating seat 130. The second locking portion 134 is configured to extend from the outer periphery of the second rotating seat 130 toward the first rotating seat 120. When the second rotating seat 130 rotates to a certain angular position, the second locking portion 134 will abut against the first locking portion 124. The interaction between the second locking portion 134 and the first locking portion 124 of the first rotating seat 120 limits the second rotating seat 130 to rotate within a range of 0-180° relative to the first rotating seat 120.

[0074] An elastic element 150 is disposed between the first rotating seat 120 and the locking element 140. In this embodiment, the elastic element 150 is a compression spring that biases the first rotating seat 120 and the locking element 140 away from each other along the axial direction. In other words, the elastic element 150 biases the first rotating seat 120 toward the base end 112 of the socket 110 and biases the locking element 140 toward the second rotating seat 130.

[0075] Thus, under the bias of the elastic element 150, the first positioning protrusion 123 of the first rotating seat 120 tends to lock into the first positioning recess 113 of the base end 112. When the user forcefully moves the first rotating seat 120, the first rotating seat 120 overcomes the bias of the elastic element 150 and moves slightly away from the base end 112, causing the first positioning protrusion 123 to disengage from the first positioning recess 113. The side edge of the first positioning protrusion 123 may be provided with an inclined chamfer so as to convert the rotational force of moving the first rotating seat 120 into an axial force, causing the first rotating seat 120 to move away from the base end 112 of the socket 110. As the first rotating seat 120 rotates relative to the base end 112, the first positioning protrusion 123 aligns with a certain first positioning recess 113. At this time, the first rotating seat 120 moves towards the socket 110 under the bias of the elastic member 150, and the first positioning protrusion 123 engages in the corresponding first positioning recess 113, thereby fixing the relative rotational position of the first rotating seat 120 and the socket 110. In this way, under the bias of the elastic member 150, the first positioning recess 113 of the socket 110 and the first positioning protrusion 123 of the first rotating seat 120 complete the process of positioning-relative rotation-repositioning.

[0076] Similarly, under the bias of the elastic element 150, a similar positioning-relative rotation-repositioning process can also be completed between the second positioning protrusion 142 of the locking element 140 and the second positioning recess 133 of the second rotating seat 130.

[0077] Therefore, the ceiling connection device 100 according to this application has a fairly simple structure, and achieves independent rotation and positioning of the first ceiling rod 300 and the second ceiling rod 400 with as few components as possible.

[0078] Now refer to Figures 13 to 16This describes how the canopy coupling device 100 according to this application is used in conjunction with the tarpaulin 500.

[0079] As shown in the figure, the two ends of the tarpaulin 500 are fixed to the first roof pole 300 and the second roof pole 400, respectively. One or more intermediate support poles 600 may also be provided in the middle of the tarpaulin 500 to maintain the shape of the tarpaulin 500. The intermediate support poles 600 are also configured to rotate around the rotation axis X.

[0080] When the relative angle between the first canopy pole 300 and the second canopy pole 400 is 180°, the tarpaulin 500 is fully deployed, as shown below. Figure 13 As shown. When the relative angle between the first canopy rod 300 and the second canopy rod 400 is any angle between 0 and 180°, for example, 120°, the tarpaulin 500 is partially unfolded, as shown. Figure 14 and Figure 15 As shown. In order to stably hold the tarpaulin 500 in the partially unfolded position, the tarpaulin 500 is provided with a retraction and fixing device, which is used to fix the first canopy rod 300 or the second canopy rod 400 to the intermediate support rod 600, or to fix one intermediate support rod 600 to another intermediate support rod 600.

[0081] For example, the closure and fastening device can be a zipper 511, such as Figure 14 As shown. Specifically, two adjacent intermediate support rods 600 may be provided with matching zippers 511. When the tarpaulin 500 is partially unfolded, the two intermediate support rods 600 overlap, and at this time the zippers 511 of the two rods can be engaged to fix the tarpaulin 500 in the partially unfolded state.

[0082] For example, the closing and fixing device can be a button 512 and a retaining ring 513, such as Figures 15 to 16 As shown. Specifically, the first canopy rod 300 (or the second canopy rod 400, the intermediate support rod 600) is provided with a strip of cloth and buttons 512 on the strip of cloth, and the intermediate support rod 600 adjacent to it is provided with a fixing ring 513. When the tarpaulin 500 is partially unfolded, the strip of cloth passes through the fixing ring 513, and the button 512 fastens the strip of cloth, thereby fixing the tarpaulin 500 in the partially unfolded state.

[0083] In summary, this application discloses a canopy joining device that enables a canopy to be detachably joined to a carrier, such as a crib. Furthermore, the canopy joining device allows for independent rotation and positioning of two canopy rods, thereby supporting both full and partial deployment of the canopy.
