During this process, the distance between the lower corner components is reduced, the upper cross bar is folded, and the distance between the upper corner components is reduced to cooperate with the storage of the lower cross bar until the locking rod moves to the second position. At this time, the lower cross bar, the column, and the upper cross bar all extend roughly in the up and down direction. At this point, the foldable children's bed is in a folded state, occupying a minimum of space, which is convenient for users to store.

[0007] In this way, the foldable children's bed provided by the present application can realize the switching of the foldable children's bed between the use state and the folded state because the locking rod can slide between the first position and the second position relative to the guide channel.

[0028] In order to more clearly understand the above-mentioned objectives, features and advantages of the present invention, the scheme of the present invention will be further described below. It should be noted that the embodiments of the present invention and the features in the embodiments can be combined with each other without conflict.

[0029] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein; it is obvious that the embodiments in the specification are only part of the embodiments of the present invention, rather than all of the embodiments.

[0030] A crib is a safe place for babies to sleep and play, whether at home or traveling. A crib can also create a safe area for babies, especially when they can crawl or are very curious. In order to take up less space and be easy to move, cribs are usually foldable.

[0031] However, the existing foldable children's beds are troublesome and laborious to fold and unfold, and are not flexible enough.

[0032] To solve the above technical problems, please refer to Figure 1 , Figure 1 Schematic diagram of a foldable child bed provided in some embodiments of the present application. The present application provides a foldable child bed 100, which may include a plurality of upper corner members 110, a plurality of foldable upper crossbars 120, a plurality of lower corner members 130, a plurality of uprights 140, a locking mechanism 150, a plurality of lower crossbars 160, and a plurality of connecting rods 170.

[0033] Specifically, a plurality of upper cross bars 120 and a plurality of upper corner components 110 form a closed upper fence, and adjacent upper cross bars 120 are rotatably connected via the upper corner components 110, wherein the upper cross bar 120 may include two sub-upper cross bars, which are rotatably connected to each other. Specifically, the two sub-upper cross bars may be rotatably connected via a rotatable connector 121, and the upper cross bar 120 may also be formed as a foldable soft bar.

[0034] One end of the column 140 is connected to the upper corner member 110, and the other end is connected to the lower corner member 130. A steering wheel 180 may be provided below the lower corner member 130 to realize the movement of the foldable child bed 100. The number of the upper corner member 110, the upper crossbar 120, the lower corner member 130 and the column 140 may be the same. Specifically, the foldable child bed 100 is formed as a rectangular parallelepiped, and the number of the upper corner member 110, the upper crossbar 120, the lower corner member 130 and the column 140 are all 4. Thus, the skeleton of the foldable child bed 100 is formed by a plurality of upper corner members 110, a plurality of upper crossbars 120, a plurality of lower corner members 130 and a plurality of columns 140.

[0035] Of course, in some other embodiments, since the frame shape of the foldable children's bed 100 (for example, circular, square, etc.) changes, the number of upper corner members 110, upper cross bars 120, lower corner members 130 and columns 140 may also be different.

[0036] See also Figure 2 and Figure 3 , Figure 2 for Figure 1 A top view of the locking mechanism shown in ; Figure 3 for Figure 2 The locking mechanism 150 may include a housing 151 and a locking rod 152. The housing 151 includes a first surface facing away from the upper fence and a second surface facing the upper fence. A guide channel is defined in the housing 151. The guide channel is in a direction from the first surface to the second surface (for example, Figure 1 The guide channel extends in the first surface to form a first opening. The locking rod 152 includes a first rod segment 1521 and a second rod segment 1522 connected to each other. The first rod segment 1521 can be slidably extended into the guide channel from the first opening, and the second rod segment 1522 is located outside the first surface.

[0037] One end of the lower cross bar 160 is rotatably connected to the lower corner member 130 , and the other end is rotatably connected to the housing 151 . The number of the lower cross bars 160 is the same as the number of the lower corner members 130 .

[0038] In the specific implementation process, please continue to refer to Figures 1 to 3 Two lower cross bars 160 can be grouped together, and the two lower cross bars 160 in a group are spaced apart in the up and down directions. The number of lower cross bars 160 is twice the number of lower corner components 130. This can ensure the stability of the lower cross bars 160 during rotation and the stability of the support of the lower cross bars 160.

[0039] One end of the connecting rod 170 is rotatably connected to the second rod segment 1522 , and the other end is connected to the lower cross bar 160 .

[0040] Among them, since the frame shape of the foldable children's bed 100 (for example, formed into a circle, a square, etc.) changes, the number of the lower corner members 130, the lower crossbar 160, and the connecting rod 170 can be specifically adjusted.

[0041] Specifically, the locking mechanism 150 can be located at the center position of multiple lower corner components 130. Taking the number of lower corner components 130 as 4 as an example, the number of lower cross bars 160 is also 4, and the 4 lower cross bars 160 cross at the position of the locking mechanism 150 to form an "X" shape structure.

[0042] Among them, the locking rod 152 includes a first position and a second position. When the locking rod 152 is in the first position, the first rod segment 1521 is located in the guide channel, and the foldable children's bed 100 is in use. When the locking rod 152 is in the second position, at least part of the first rod segment 1521 is located outside the first opening, and the foldable children's bed 100 is in a folded state.

[0043] When the locking rod 152 is in the first position, the foldable child bed 100 is in use. When the locking rod 152 is moved from the first position to the second position, the locking rod 152 moves downward relative to the shell 151, that is, it drives the connecting rod 170 to drag the lower cross bar 160. Under the pulling of the connecting rod 170, the lower cross bar 160 rotates downward and in the direction of the shell 151, that is, multiple lower cross bars 160 are stored toward the locking mechanism 150. During this process, the distance between the lower corner components 130 is reduced, the upper cross bar 120 is folded, and the distance between the upper corner components 110 is reduced to cooperate with the storage of the lower cross bar 160 until the locking rod 152 moves to the second position. At this time, the lower cross bar 160, the column 140, and the upper cross bar 120 all extend roughly in the up and down direction. At this point, the foldable child bed 100 is in a folded state, occupying a minimum space, which is convenient for users to store.

[0044] In this way, the foldable children's bed 100 provided in the present application can switch the foldable children's bed 100 between the use state and the folded state because the locking rod 152 can slide between the first position and the second position relative to the guide channel. The user only needs to pull the locking rod 152 from the first position to the second position, and the folding operation is simple and effortless.

[0045] In some embodiments of this application, please refer to Figure 2 , the radial dimension of the second rod segment 1522 is larger than the radial dimension of the second opening, and when the locking rod 152 is in the second position, the second rod segment 1522 abuts against the first surface. It can be understood that in the process of the locking rod 152 moving from the second position to the first position, the second rod segment 1522 moves toward the first surface, and setting the radial dimension of the second rod segment 1522 larger than the first opening can prevent the second rod segment 1522 from moving into the guide channel, and further prevent the locking rod 152 from exceeding the first position (i.e., the locking rod 152 moves to the side of the first position away from the second position) in the process of moving from the second position to the first position, thereby preventing the foldable child bed 100 from shaking up and down during use, and ensuring the stability of the foldable child bed 100 in use.

[0046] In some embodiments of this application, please refer to Figures 2 to 4 , Figure 4 for Figure 3 Schematic diagram of the locking rod and the unlocking member shown in . A connecting pin 1523 is provided on the circumferential outer side of the second rod segment 1522, and the connecting pin 1523 extends toward the circumferential outer side of the second rod segment 1522. The connecting pin 1523 is rotatably connected to the connecting rod 170, and the connecting pin 1523 corresponds to the connecting rod 170 one by one. Therefore, by providing the connecting pin 1523, an installation position is provided for the rotatable connection of the connecting rod 170.

[0047] Among them, taking the number of lower corner components 130 as 4 as an example, the number of lower cross bars 160 is 4, the number of connecting rods 170 is 4, the number of connecting pins 1523 is 4, and the connecting pins 1523 extend on the diagonal of the quadrilateral surrounded by the lower corner components 130, so that the two opposite lower cross bars 160 can rotate on the plane, thereby enhancing the stability of the lower cross bar 160 rotating between the use state and the folded state of the foldable children's bed 100.

[0048] In some embodiments of this application, please refer to Figure 3 and Figure 4 The guide channel passes through the second surface to form a second opening, and the end of the first rod segment 1521 close to the second opening is provided with a clamping groove 1525 recessed toward the first surface, and the inner wall of the clamping groove 1525 is provided with a clamping cross bar 1526. Specifically, the clamping groove 1525 may include a first inner wall and a second inner wall opposite to each other in a first direction, and the clamping cross bar 1526 extends from the first inner wall toward the second inner wall, and is connected to the first inner wall and the second inner wall.

[0049] The locking mechanism 150 may further include an unlocking member 153, which may include a connected rotating portion 1531 and a clamping portion 1532, wherein the rotating portion 1531 is rotatably installed on the second opening, and the clamping portion 1532 extends into the second opening, and the clamping portion 1532 is provided with a clamping notch 1533 which can be clamped with the clamping cross bar 1526, and the unlocking member 153 includes a locking position and an unlocking position, and the unlocking member 153 can rotate between the locking position and the unlocking position, and when the unlocking member 153 is located at the locking position, the clamping cross bar 1526 is clamped into the clamping notch 1533, and the locking rod 152 is fixed in the first position, and when the unlocking member 153 is located at the unlocking position, the clamping cross bar 1526 is disengaged from the clamping groove 1525, and the locking rod 152 can move between the first position and the second position.

[0050] Therefore, by setting the unlocking member 153, the locking rod 152 can be fixed in the first position, so that the foldable children's bed 100 can be guaranteed to be stable in use. When the user needs to fold the foldable children's bed 100, the unlocking member 153 needs to be rotated from the locking position to the unlocking position first to avoid the folding of the foldable children's bed 100 by mistake.

[0051] In some embodiments of this application, please continue to refer to Figures 2 to 4The unlocking member 153 further includes a hand-held portion 1534, which is connected to the rotating portion 1531 and is located outside the second opening. Therefore, by providing the hand-held portion 1534, it is convenient for the user to rotate the unlocking member 153 between the locked position and the unlocked position. At the same time, after the user rotates the unlocking member 153 to the unlocked position, the user can pull the housing 151 through the hand-held portion 1534, so that the housing 151 and the locking rod 152 move relative to each other, so that the locking rod 152 moves from the first position to the second position, so that the foldable child bed 100 is switched from the use state to the folded state.

[0052] In some embodiments of the present application, when the unlocking member 153 is in the locked position, the extending direction of the hand-held portion 1534 is parallel to the second surface. It is understandable that when the unlocking member 153 is in the locked position, the locking rod 152 is in the first position, the foldable bed for children is in use, and the extending direction of the hand-held portion 1534 is parallel to the second surface, which can ensure that the second surface is relatively flat, avoid obvious bulges on the bed surface, and ensure a good user experience.

[0053] For further information, please refer to Figure 3 and Figure 4 The second surface is provided with an avoidance groove 154, and the second opening is formed at the bottom wall of the avoidance groove 154. When the unlocking member 153 is in the locked position, the hand-held portion 1534 is located in the avoidance groove 154. Therefore, by providing the avoidance groove 154, it can be ensured that when the unlocking member 153 is in the locked position, that is, the foldable bed for children is in use, the second surface can be kept flat, and bulges can be avoided on the bed surface, further ensuring a good user experience.

[0054] In some embodiments of this application, please continue to refer to Figure 3 and Figure 4 The unlocking member 153 further includes a rotating shaft and a torsion spring 1535. The rotating shaft penetrates the rotating portion 1531 and the inner wall of the avoidance groove 154. The torsion spring 1535 is sleeved on the rotating shaft. One torsion arm of the torsion spring 1535 abuts against the rotating portion 1531, and the other torsion arm abuts against the inner wall of the avoidance groove 154. Therefore, by providing the torsion spring 1535, the unlocking member 153 can be automatically reset from the unlocking position to the locking position.

[0055] In some embodiments of this application, please continue to refer to Figure 3 and Figure 4 A tension hole 1536 is provided at one end of the hand-held portion 1534 away from the rotating portion 1531, and the tension hole 1536 is used to pass a pull rope. Thus, by passing the pull rope, the force arm of the hand-held portion 1534 can be extended, thereby reducing the force of the user to rotate the unlocking member 153 and pull the housing 151. At the same time, the design of the pull rope is convenient for the user to operate.

[0056] In some embodiments of this application, please refer to Figure 5 , Figure 5 for Figure 1 A bottom view of the locking structure is shown in FIG. A guide groove 1524 is provided on one of the inner wall of the guide channel and the outer wall of the locking rod 152, and a guide protrusion 1511 matching the guide groove 1524 is provided on the other. The guide groove 1524 is in the direction from the first surface to the second surface (i.e. Figure 5 Thus, by providing the guide groove 1524 and the guide protrusion 1511 that cooperate with each other, it is possible to prevent the locking rod 152 from rotating in the circumferential direction during the movement of the locking rod 152 between the first position and the second position, further ensuring the stability of the movement of the locking rod 152 between the first position and the second position, improving product quality, and improving the user experience.

[0057] Specifically, the inner wall of the guide channel may be provided with a guide groove 1524 , and the outer wall of the locking rod 152 may be provided with a guide protrusion 1511 , or the inner wall of the guide channel may be provided with a guide protrusion 1511 , and the outer wall of the locking rod 152 may be provided with a guide groove 1524 .

[0058] Furthermore, there may be multiple guide grooves 1524 , and there may be multiple guide protrusions 1511 , and the multiple guide grooves 1524 correspond one-to-one to the multiple guide protrusions 1511 .

[0059] In some embodiments of this application, please continue to refer to Figure 1 The foldable children's bed 100 may further include an auxiliary rod 190, one end of which is rotatably connected to the shell 151, and the other end is bent or inclined toward the ground. When the foldable children's bed 100 is in use, the auxiliary rod 190 can serve as a bed leg to further ensure the stability of the foldable children's bed 100 during use.

[0060] There may be a plurality of auxiliary rods 190 .
