[0047] Please refer to Figures 1 to 7 The present application provides a child bed 100, in an embodiment of the present application, the child bed 100 includes a stand 10, an upper support rod 20 provided at the upper end of the stand 10, a lower support rod 30 provided at the lower end of the stand 10, a locking member 40 movably provided on the upper support rod 20, and a linkage mechanism 50; the upper support rod 20 and the lower support rod 30 both have an unfolded state and a folded state, the locking member 40 has a locking position and an unlocking position, the locking member 40 locks the upper support rod 20 in position when in the unfolded state at the locking position, and the locking member 40 releases the locking of the upper support rod 20 when in the unlocking position; the linkage mechanism 50 includes a sliding member 51 and a traction cable 52, the sliding member 51 is movably provided on the stand 10, and the traction cable 52 connects the sliding member 51 and the locking member 40; when the lower support rod 30 is folded by rotating, the lower support rod 30 can drive the stand 10 to move towards the lower support rod 30, and drive the sliding member 51 to move relative to the stand 10, so as to drive the traction cable 52 to move the locking member 40 to the unlocking position.

[0048] The stand 10 can be arranged in an up-and-down direction when the child bed 100 is in a normal use state. In a cross section perpendicular to the extending direction of the stand 10, the cross section of the stand 10 can be circular, of course, it can also be square or rectangular, etc. In addition, the number of stands 10 can be multiple, and the multiple stands 10 are arranged in a horizontal direction. Moreover, the lines connecting between two adjacent stands 10 are sequentially connected into a closed loop. For example, when the number of stands 10 is four, the lines connecting between two adjacent stands 10 are sequentially connected into a square or a rectangle.

[0049] The upper support rod 20 is arranged at the upper end of the stand rod 10, can be arranged in a horizontal direction or slightly inclined (for example, an angle less than or equal to 10° is formed with the horizontal direction), and can be located between two adjacent stand rods 10. The number of upper support rods 20 can correspond to the number of stand rods 10. For example, when the stand rod 10 is provided with four, the number of upper support rods 20 can also be four, and each upper support rod 20 is located between two adjacent stand rods 10. In addition, in order to facilitate the upper support rod 20 to have an unfolded state and a folded state, each upper support rod 20 can include two upper rod bodies 21, the proximal end of the two upper rod bodies 21 is rotatably connected, and the distal end is rotatably connected to the corresponding stand rod 10. At this time, in the unfolded state, the two upper rod bodies 21 can form a straight angle or an angle close to a straight angle. In the folded state, the two upper rod bodies 21 can form an acute angle. In addition, when the upper support rod 20 is folded, the proximal end of the two upper rod bodies 21 can be folded downward, or the proximal end of the two upper rod bodies 21 can be folded horizontally towards the inside of the space surrounded by the plurality of stand rods 10, and the application does not limit the folding direction of the upper support rod 20. In addition, the proximal end of the two upper rod bodies 21 can be directly rotatably connected. Of course, an intermediate connecting piece 60 can be arranged between the proximal end of the two upper rod bodies 21, and the proximal end of the two upper rod bodies 21 is rotatably connected to the intermediate connecting piece 60, so as to indirectly rotatably connect the proximal end of the two upper rod bodies 21. At this time, the intermediate connecting piece 60 is convenient to give a connection position to realize the rotation connection between the two rod bodies. In addition, the upper rod body 21 and the stand rod 10 can also be directly rotatably connected. Of course, an angle connecting piece 70 can be arranged between the stand rod 10 and the two upper rod bodies 21 adjacent to the stand rod 10, and the stand rod 10 and the two upper rod bodies 21 adjacent to the stand rod 10 are rotatably connected to the angle connecting piece 70, so as to indirectly rotatably connect the upper rod body 21 and the stand rod 10. At this time, the angle connecting piece 70 is convenient to give a connection position to realize the rotation connection between the stand rod 10 and the two upper rod bodies 21 adjacent to the stand rod 10. In addition, it should be noted that the rotation connection proposed in the application can be that one of the connected objects is provided with a plug shaft, and the other is provided with a plug hole, and the plug shaft is inserted into the plug hole to realize the rotation connection between the connected objects. Of course, the connected objects can also be provided with a through hole, and the rotation connection between the connected objects is realized by directly inserting the plug shaft. That is, the application does not limit the way of rotation connection. In addition, in the cross section perpendicular to the extension direction of the upper rod body 21, the cross section of the upper rod body 21 can be circular, of course, it can also be square or rectangular, etc.

[0050] The lower support rod 30 is arranged at the lower end of the stand rod 10, can be arranged in a horizontal direction or slightly inclined (for example, an angle less than or equal to 10° with the horizontal direction), and can be located between two diagonal stand rods 10 or between two adjacent stand rods 10. When the lower support rod 30 is located between two diagonal stand rods 10, the number of lower support rods 30 can be half of the number of stand rods 10. For example, when the stand rod 10 is provided with four, the number of lower support rods 30 can be two, and each lower support rod 30 is located between two diagonal stand rods 10 to form an X shape. When the lower support rod 30 is located between two adjacent stand rods 10, the number of lower support rods 30 can correspond to the number of stand rods 10. For example, when the stand rod 10 is provided with four, the number of lower support rods 30 can also be four, and each lower support rod 30 is located between two adjacent stand rods 10. In addition, in order to facilitate the lower support rod 30 to have an unfolded state and a folded state, each lower support rod 30 can include two lower rod bodies 31, and the proximal end of the two lower rod bodies 31 is rotatably connected, and the distal end is rotatably connected to the corresponding stand rod 10 or the sliding member 51 on the corresponding stand rod 10. At this time, in the unfolded state, the two lower rod bodies 31 can form a straight angle or an angle close to a straight angle. In the folded state, the two lower rod bodies 31 can form an acute angle. In addition, when the lower support rod 30 is folded, when the lower support rod 30 is located between two diagonal stand rods 10, the proximal end of the two lower rod bodies 31 can be folded upward. When the lower support rod 30 is located between two adjacent stand rods 10, the horizontal direction can be folded toward the inside of the space surrounded by the plurality of stand rods 10, and the application does not limit the folding direction of the lower support rod 30. In addition, in order to facilitate the rotation connection of the two lower rod bodies 31 in the lower support rod 30, a base 80 can be arranged between the two lower rod bodies 31, so that the connection position is facilitated by the base 80 to facilitate the rotation installation of the lower rod body 31. Especially when the lower support rod 30 is located between two diagonal stand rods 10, one base 80 can realize the rotation connection of four lower rod bodies 31 in two lower support rods 30, so as to simplify the number of parts and simplify the structure, and also facilitate the arrangement of two lower support rods 30 at the same height. In addition, when no locking structure is arranged between the lower support rod 30 and the stand rod 10 to lock the unfolded state of the two, the gravity of the base 80 can also drive the lower support rod 30 to unfold and support the stand rod 10. Of course, the locking structure including the elastic bead can also be arranged between the lower support rod 30 and the stand rod 10. The elastic bead can be arranged in one of the lower support rod 30 and the stand rod 10, and can be elastically extended and inserted into the other of the lower support rod 30 and the stand rod 10, so as to lock the lower support rod 30 and the stand rod 10 in the unfolded state. When the base 80 is lifted, the elastic bead can be retracted to unlock the lower support rod 30 and the stand rod 10, so that the two can be close to each other and folded.

[0051] The locking member 40 is movably arranged on at least one of the upper rod bodies 21 of the upper support rod 20 and has a locking position and an unlocking position when moving relative to the upper support rod 20. The locking manner of the locking member 40 to the two upper rod bodies 21 in the unfolded state can be that the locking member 40 is movably arranged on one of the two upper rod bodies 21, and when the two rod bodies are rotated to the unfolded state, the locking member 40 can be inserted into the other one of the two upper rod bodies 21 to block the relative rotation of the two upper rod bodies 21. Alternatively, the locking member 40 is movably arranged on one of the two upper rod bodies 21, and the end of the two upper rod bodies 21 close to each other can be provided with meshing gears, and when the two rod bodies are rotated to the unfolded state, the locking member 40 can be inserted into the two adjacent teeth of the gear on the same upper rod body 21 as the locking member 40 to limit the gear and block the relative rotation of the two upper rod bodies 21. It can be seen that the locking manner of the locking member 40 to the upper support rod 20 in the unfolded state is not limited in the present application, as long as the locking member 40 can block the relative rotation of the two upper rod bodies 21 in the upper support rod 20 when moving to the locking position, and the two upper rod bodies 21 in the upper support rod 20 can rotate relative to each other when the locking member 40 moves to the unlocking position. In addition, when the locking member 40 moves to the unlocking position, the end of the two upper rod bodies 21 in the upper support rod 20 close to each other can be folded downward under the action of gravity to improve the folding convenience of the child bed 100. In addition, the locking member 40 can be slidingly arranged on the upper support rod 20, or can be rotatably arranged.

[0052] The linkage mechanism 50 can receive the drive of the lower support rod 30 when folding by the sliding member 51, and then drive the locking member 40 to move from the locking position to the unlocking position by the traction cable 52. The sliding member 51 can be arranged on the outside of the stand rod 10, and can also be arranged on the inside of the stand rod 10. In addition, the sliding member 51 can be driven to slide downward when the lower support rod 30 is folded, and can also be driven to slide upward. In addition, the lower support rod 30 can drive the sliding member 51 by cooperating with the connecting rod 53 as described below, and can also abut against the sliding member 51 to drive it. The application does not limit the driving mode of the sliding member 51 by the lower support rod 30. In addition, the traction cable 52 can be arranged on the outside of the stand rod 10 and the upper support rod 20, and can also be arranged on the inside of the stand rod 10 and the upper support rod 20. The material of the traction cable 52 can be metal, and can also be nylon, etc. The application does not limit the material of the traction cable 52. In addition, one traction cable 52 can be arranged on each stand rod 10, and the end of the traction cable 52 away from the sliding member 51 can be arranged on the upper rod body 21 adjacent to the stand rod 10 and connected with the locking member 40 on the upper rod body 21. Alternatively, the end of the traction cable 52 away from the sliding member 51 can form two branches to be arranged on the two upper rod bodies 21 adjacent to the stand rod 10 and connected with the locking members 40 on the two upper rod bodies 21, respectively. Of course, two traction cables 52 can be arranged on each stand rod 10, and the ends of the two traction cables 52 connected with the sliding member 51 can be arranged on the two upper rod bodies 21 adjacent to the stand rod 10 and connected with the locking members 40 on the two upper rod bodies 21, respectively. It can be seen that the application does not limit the number and structure of the traction cable 52. In addition, the traction cable 52 and the sliding member 51 can be directly connected, and can also be indirectly connected through the fixing seat 54 as described below. The application does not limit this.

[0053] The child bed 100 of the technical scheme of the present application, when the user drives the lower support rod 30 of the child bed 100 to rotate and fold, the vertical rod 10 can be brought closer to the lower support rod 30. At the same time, due to the linkage mechanism 50 including the sliding piece 51 and the traction cable 52 provided on the child bed 100, the lower support rod 30 can also drive the sliding piece 51 to move relative to the vertical rod 10 during the process of rotating and folding. At this time, the sliding sliding piece 51 can drive the locking piece 40 to move to the unlocking position through the traction cable 52, so as to realize the unlocking of the limiting and locking of the upper support rod 20, so that the upper support rod 20 can be rotated and folded. Therefore, the structure of the child bed 100 in the present scheme realizes the unlocking of the upper support rod 20 during the rotating and folding process of the lower support rod 30. At this time, it is not necessary to perform a relatively complicated step-by-step unlocking operation on the lower support rod 30 and the upper support rod 20 of the child bed 100, which simplifies the folding process of the child bed 100, thereby facilitating the convenience of using the child bed 100. Moreover, at this time, the linkage mechanism 50 receives the driving force of the lower support rod 30 through the sliding piece 51 during the rotating and folding of the lower support rod 30, and the structure cooperation between the two is reliable, thereby facilitating the stability of the unlocking of the upper support rod 20 during the rotating and folding of the lower support rod 30. At the same time, it also makes the structure relatively simple, thereby facilitating the convenience of manufacturing the child bed 100.

[0054] Please refer to Figure 1 and Figure 2 , and Figure 5 and Figure 6 In an embodiment of the present application, the end of the lower support rod 30 close to the vertical rod 10 is rotationally connected to the sliding piece 51, and the linkage mechanism 50 further includes a connecting rod 53, both ends of the connecting rod 53 being rotationally connected to the vertical rod 10 and the end of the lower support rod 30 close to the vertical rod 10; in the unfolded state, the rotationally connected position of the lower support rod 30 and the sliding piece 51 is closer to the vertical rod 10 than the rotationally connected position of the lower support rod 30 and the connecting rod 53.

[0055] In the embodiment, one of the lower rod bodies 31 in the lower supporting rod 30 is rotationally connected to the sliding member 51, and a connecting rod 53 rotationally connected to the upright rod 10 and the lower rod body 31 is arranged in cooperation, so that the upright rod 10, the sliding member 51, the lower rod body 31 and the connecting rod 53 can constitute a crank slider mechanism. In this way, when the lower supporting rod 30 is folded and unfolded, the sliding member 51 can be driven to slide on the upright rod 10. Moreover, the upright rod 10, the sliding member 51, the lower supporting rod 30 and the connecting rod 53 have a connection relationship at this time, which is conducive to improving the stability of the driving of the sliding member 51 by the lower supporting rod 30 when the lower supporting rod 30 is folded and unfolded. The connecting rod 53 can be a first segment body 531 and a second segment body 532 at an included angle as described below. Of course, it can also be a linear segment body. In addition, the cross section of the connecting rod 53 can be circular, square or rectangular, etc. It can be seen that the shape of the connecting rod 53 is not limited in the present application. In addition, one connecting rod 53 can be arranged between each upright rod 10 and the lower supporting rod 30, and of course, two connecting rods 53 can also be arranged, which are arranged opposite to each other and located on both sides of the lower supporting rod 30 to improve the stability of the connection.

[0056] For reference Figures 1 to 4 In an embodiment of the present application, in the unfolded state, the rotation connection position of the connecting rod 53 and the upright rod 10 is located above the sliding member 51; when the two lower rod bodies 31 are folded upward at one end, the upright rod 10 can be brought close to the lower rod body 31, and the sliding member 51 can be driven to move downward, so that the two upper rod bodies 21 can be folded downward at one end.

[0057] In the embodiment, the rotation connection position of the connecting rod 53 and the upright rod 10 is arranged above the sliding member 51, so that when the lower supporting rod 30 is folded, the two lower rod bodies 31 in the lower supporting rod 30 can be folded upward at one end. This folding direction facilitates the lifting operation of the user, which is conducive to further improving the convenience of using the child bed 100. Moreover, the position of the lower supporting rod 30 can be arranged relatively low to improve the space inside the child bed 100. In addition, when the lower supporting rod 30 is folded, the sliding member 51 is driven to move downward, so that the two upper rod bodies 21 can be folded downward at one end. At this time, after the locking member 40 moves to the unlocking position and the upper supporting rod 20 is unlocked, the two upper rod bodies 21 in the upper supporting rod 20 can be automatically folded downward under the action of gravity, which further improves the convenience of folding the child bed 100.

[0058] For reference Figure 5 and Figure 6In an embodiment of the present application, the connecting rod 53 comprises a first segment 531 and a second segment 532 connected and arranged at an angle, the first segment 531 is rotationally connected to the upright rod 10 at an end away from the second segment 532, and the second segment 532 is rotationally connected to the lower support rod 30 at an end away from the first segment 531.

[0059] In the embodiment, the connecting rod 53 is arranged as the first segment 531 and the second segment 532 arranged at an angle, and the angle enclosed by the first segment 531 and the second segment 532 is directed towards the inside of the space enclosed by the plurality of upright rods 10. At this time, the space occupied by the connecting rod 53 in the horizontal direction can be reduced, thereby facilitating the folding compactness between the subsequent upright rods 10 and the lower support rod 30.

[0060] For reference Figure 5 and Figure 6 In an embodiment of the present application, the extension direction of the first segment 531 is parallel to the up-down direction, and the extension direction of the second segment 532 intersects the up-down direction and the horizontal direction; the connecting rod 53 further comprises an arc segment 533, both ends of the arc segment 533 are connected to the end of the first segment 531 and the second segment 532 close to each other, and are tangent to the first segment 531 and the second segment 532.
