Description

Technical Field

[0001] The present application relates to the technical field of furniture, and in particular to a bed frame and a children's bed. Background Art

[0002] Children's beds are mainly used to provide a place for children to rest or play. Usually, in order to facilitate the storage or transportation of children's beds, they are often set as a foldable structure to reduce the size. Generally, children's beds are composed of columns and multiple handrail tubes that can be folded and connected between the columns, and the multiple handrail tubes are pivoted to each other. The handrail tubes are pivoted to approach each other, thereby driving the columns to move closer to each other to achieve the folding of the children's bed. However, the common handrail tubes are limited by the structure, and the upper surface of the handrail tubes is uneven after pivoting, which easily leads to the children's bed covering laid on the handrail tubes not fitting well and the appearance is not neat.

[0003] In addition, in order to facilitate the rest of small babies, a hammock is generally installed in the cribs currently on the market. In order to ensure that the mattress on the hammock is flat and makes the baby more comfortable when using it, the hammock is generally provided with a support structure for supporting the mattress, and the support structure can be folded together with the crib. However, the support structure of the cribs currently on the market still has a large volume after being folded, which is not conducive to storage and transportation. Summary of the invention

[0149] In order to make the above-mentioned purposes, features and advantages of the present application more obvious and easy to understand, the specific implementation methods of the present application are described in detail below in conjunction with the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of the present application. However, the present application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the present application, so the present application is not limited by the specific embodiments disclosed below.

[0150] Figures 1 to 4 The schematic diagram of a child bed 1000 in one embodiment of the present application is schematically shown. The child bed 1000 is mainly used to provide a place for children or infants to rest or play. Specifically, the child bed 1000 is generally a rectangular frame structure, including a bed frame 10 (see Figure 5 , Fig.13 or Fig.17 ) and a child bed covering 1200 (such as a cloth cover, etc., see Figures 1 to 4 ), wherein the bed frame 10 is a foldable structure, so that the child bed 1000 can be folded and switched between an unfolded state and a folded state. The child bed 1000 has a small volume after being folded, which is convenient for storage and transportation.

[0151] Figure 5 FIG. 1 shows a three-dimensional view of a bed frame 10 provided according to the first embodiment of the present application. The bed frame 10 includes: a first column 111, a second column 112, and an armrest tube mechanism 120. The second column 112 is arranged opposite to the first column 111. The armrest tube mechanism 120 is movably connected between the first column 111 and the second column 112. The armrest tube mechanism 120 is in the unfolded position (see FIG. 111 ). Figure 5 and Figure 6 ) and the collapsed position (see Figure 8 When the armrest tube mechanism 120 is in the unfolded position, the armrest tube mechanism 120 is at least partially parallel to the horizontal plane.

[0152] The above-mentioned bed frame 10 can have an extended position and a folded position by movably connecting the armrest tube mechanism 120 between the first column 111 and the second column 112. When the armrest tube mechanism 120 is in the folded position, the entire bed frame 10 can be folded to reduce the volume of the bed frame 10 for easy storage and transportation. Since the armrest tube mechanism 120 is at least partially parallel to the horizontal plane when it is in the extended position, the child bed cover 1200 (such as a cloth cover) installed on the armrest tube mechanism 120 tends to be flat when the armrest tube mechanism 120 is in the extended position, so that it fits better with the armrest tube mechanism 120, thereby making the bed frame 10 covered with the child bed cover 1200 more neat in appearance.

[0153] In some embodiments, there are multiple first columns 111 and multiple second columns 112, and the multiple first columns 111 and the multiple second columns 112 are alternately arranged in the circumferential direction, and a handrail tube mechanism 120 is provided between adjacent first columns 111 and second columns 112. In this way, when each handrail tube mechanism 120 is in the deployed position, each first column 111, each handrail tube mechanism 120 and each second column 112 are sequentially connected and enclosed to form a ring structure. It should be understood that the "multiple" used in this application means at least two.

[0154] Specifically, see Figure 5 There are two first columns 111 and two second columns 112, and four armrest tube mechanisms 120. When each armrest tube mechanism 120 is in the unfolded position, each first column 111 is connected to each second column 112 through the armrest tube mechanism 120 to form a rectangular bed frame 10. Figures 5 to 8 In some embodiments, the handrail tube mechanism 120 includes a first handrail tube group 121, and the first handrail tube group 121 includes a first handrail tube 122. The first handrail tube 122 has a first pivot end 1221A and a first sliding end 1221B. The first pivot end 1221A is pivoted to the first column 111 or the second column 112, and the first sliding end 1221B is pivoted and slidably connected to the second column 112 or the first column 111. In other words, when the first pivot end 1221A is pivoted to one of the first column 111 and the second column 112, the first sliding end 1221B is pivoted and slidably connected to the other. When the handrail tube mechanism 120 is in the deployed position, the first column 111 and the second column 112 are away from each other (see Figure 5 and Figure 6 ), and the corresponding first handrail tube 122 is at least partially parallel to the horizontal plane.

[0155] See also Figure 6 and Figure 7In some embodiments, the first armrest tube 122 includes a first tube section 1222 and a second tube section 1223 that are connected to each other and arranged at an angle. The first end of the first tube section 1222 away from the second tube section 1223 is a first pivot end 1221A, and the first end of the second tube section 1223 away from the first tube section 1222 is a first sliding end 1221B. The first pivot end 1221A and the first sliding end 1221B are arranged at the ends of each tube section, which is conducive to improving the convenience of connection between the first armrest tube 122 and the first column 111 and the second column 112; at the same time, when the armrest tube mechanism 120 is in the unfolded position, the first armrest tube 122 has the maximum unfolded length, so that the distance between the first column 111 and the second column 112 reaches the maximum, thereby enabling the bed frame 10 to have a larger accommodation space in the unfolded state to support the child bed cover 1200, thereby increasing the area of ​​the child bed cover 1200 in the unfolded position, and providing a larger space for children to rest or entertain. More specifically, see Figure 6 and Figure 7 When the handrail tube mechanism 120 is in the unfolded position, the first tube segment 1222 is parallel to the horizontal plane, and the second tube segment 1223 extends downward from the second end of the first tube segment 1222 .

[0156] In some embodiments, the angle α between the first tube segment 1222 and the second tube segment 1223 is greater than 90°.

[0157] More specifically, in some embodiments, the angle α between the first pipe segment 1222 and the second pipe segment 1223 is 150°. Of course, in some alternative embodiments, the angle α between the first pipe segment 1222 and the second pipe segment 1223 can also be 100°, 120°, or 140°, etc., which is not specifically limited here.

[0158] In order to improve the convenience of connecting the first handrail tube 122 to the first column 111 and the second column 112, and to improve the convenience of switching the first handrail tube 122 between the unfolded position and the folded position, see Figure 6 and Figure 8 In some embodiments, the bed frame 10 further includes a top corner 130. More specifically, in some embodiments, the first column 111 or the second column 112 is provided with a top corner 130, and the top corner 130 has a first pivoting portion Q1, and the first pivoting portion Q1 is used to pivot with the first pivoting end 1221A.

[0159] Furthermore, in some embodiments, the bed frame 10 also includes a sliding member 140. The sliding member 140 is slidably provided on the first column 111 or the second column 112. The sliding member 140 is provided with a second pivot portion Q2, and the second pivot portion Q2 is used to pivot with the first sliding end 1221B. When the vertex 130 connected to a first handrail tube 122 is set on one of the first column 111 and the second column 112, the sliding member 140 connected to the first handrail tube 122 is set on the other. When the user needs to switch the bed frame 10 from the expanded state to the folded state, that is, when the handrail tube mechanism 120 is switched from the expanded position to the folded position (by Figure 6 The displayed status switches to Figure 8 When the user pushes or pulls the sliding member 140, the sliding member 140 drives the first sliding end 1221B of the first handrail tube 122 to move downward (in the F1 direction) along the corresponding first column 111 or second column 112, thereby enabling the first sliding end 1221B of the first handrail tube 122 to rotate at the second pivoting portion Q2 of the sliding member 140, and at the same time enabling the first pivoting end 1221A of the first handrail tube 122 to rotate at the first pivoting portion Q1 of the top corner 130, thereby driving the first column 111 and the second column 112 to move closer to each other. When the user needs to switch the bed frame 10 from the folded state to the unfolded state, that is, when the handrail tube mechanism 120 is switched from the folded position to the unfolded position (by Figure 8 The displayed status switches to Figure 6 When in the state shown in the figure, the sliding member 140 is pushed, so that the sliding member 140 drives the first sliding end 1221B of the first handrail tube 122 to move upward (F2 direction) along the corresponding first column 111 or the second column 112, so that the first sliding end 1221B of the first handrail tube 122 can rotate at the second pivot portion Q2 of the sliding member 140, and at the same time, the first pivot end 1221A of the first handrail tube 122 can rotate at the first pivot portion Q1 of the top angle 130, thereby driving the first column 111 and the second column 112 to move away from each other.

[0160] More specifically, in some embodiments, Figure 5 and Figure 6As shown, in the annular bed frame 10 formed by connecting and enclosing a plurality of first columns 111, a plurality of second columns 112, and a plurality of first handrail tube groups 121, each vertex 130 arranged on the first column 111 or the second column 112 includes a first vertex portion 131 and a second vertex portion 132, and the first vertex portion 131 and the second vertex portion 132 are connected to each other and are arranged at an angle. The first vertex portion 131 and the second vertex portion 132 are both provided with a first pivoting portion Q1, and the first pivoting portion Q1 is used to pivot with the first pivoting end 1221A of the first handrail tube 122. Similarly, each sliding member 140 on the second column 112 or the first column 111 may also include a first sliding portion 141 and a second sliding portion 142, and the first sliding portion 141 and the second sliding portion 142 are connected to each other and are arranged at an angle. The first sliding portion 141 and the second sliding portion 142 are both provided with a second pivoting portion Q2, and the second pivoting portion Q2 is used to pivot with the first sliding end 1221B of the first handrail tube 122. Thus, when the sliding member 140 slides on the second column 112 or the first column 111, the first sliding ends 1221B of the two first handrail tubes 122 connected to the same sliding member 140 will slide up and down with the sliding member 140 and pivot relative to the sliding member 140. At the same time, the first pivoting ends 1221A of the two first handrail tubes 122 connected to the same vertex 130 will pivot relative to the vertex 130.

[0161] See also Figures 5 to 8 In this embodiment, the first handrail tube set 121 includes two first handrail tubes 122. The first pivot end 1221A of one of the first handrail tubes 122 is pivotally connected to the first column 111, and the first sliding end 1221B of one of the first handrail tubes 122 is pivotally connected and slidably connected to the second column 112. The first pivot end 1221A of the other first handrail tube 122 is pivotally connected to the second column 112, and the first sliding end 1221B of the other first handrail tube 122 is slidably pivotally connected to the first column 111. In other words, when the first handrail tube group 121 includes two first handrail tubes 122, the first pivot end 1221A of one of the first handrail tubes 122 is pivoted to the first column 111, and the first sliding end 1221B of the first handrail tube 122 is pivoted and slidably connected to the second column 112; while the first pivot end 1221A of the other first handrail tube 122 is pivoted to the second column 112, and the first sliding end 1221B of the first handrail tube 122 is slidably pivoted to the first column 111. More specifically, when the handrail tube mechanism 120 is in the deployed position, the two first handrail tubes 122 in the first handrail tube group 121 are arranged side by side in the horizontal direction, and the projections of the first tube sections 1222 of the two first handrail tubes 122 on the vertical plane parallel to the LR direction (left-right direction) and perpendicular to the horizontal plane at least partially overlap (see Figure 7 ).

[0162] Combine the following Figure 5 and Figure 7 , to explain the meaning of the above-mentioned "the two first handrail tubes 122 are arranged side by side in the horizontal direction, and the projections of the first tube sections 1222 of the two first handrail tubes 122 on the vertical plane parallel to the LR direction (left-right direction) and perpendicular to the horizontal plane at least partially overlap".

[0163] Figure 5 The schematic diagram shows a bed frame 10 in this embodiment, which includes two first upright posts 111, two second upright posts 112 and a handrail tube mechanism 120. When the bed frame 10 is in an unfolded state, the bed frame 10 is generally in a square structure and is generally symmetrical left-right and front-back. Figure 5 and Figure 7 , taking one of the first columns 111 and the second column 112 arranged along the left-right direction as an example, when the two first handrail tubes 122 arranged between the two are in the unfolded position, the first tube sections 1222 of the two first handrail tubes 122 are arranged in parallel in the horizontal direction (specifically, they can be regarded as the front-to-back direction), and the two first tube sections 1222 are partially overlapped in the front-to-back direction. Alternatively, taking one of the first columns 111 and the second column 112 arranged along the front-to-back direction as an example, when the two first handrail tubes 122 arranged between the two are in the unfolded position, the first tube sections 1222 of the two first handrail tubes 122 are arranged in parallel in the horizontal direction (specifically, they can be regarded as the left-to-right direction), and the two first tube sections 1222 are partially overlapped in the left-to-right direction.

[0164] It should be noted that, unless otherwise clearly specified and limited, the directional terms such as "front", "rear", "left", and "right" of the bed frame 10 in the various embodiments of the present application are based on the "front", "rear", "left", and "right" directions of the bed frame 10 shown in the figure, and the arrows B and P in the figure schematically indicate the "front" and "rear" directions, and the arrows L and R in the figure schematically indicate the "left" and "right" directions. These directional terms are only used to make the description of the embodiments of the present application clearer, and are not used to improperly limit the scope of protection of the present application.

[0165] See also Figure 5 and Figure 6 In some embodiments, both the first column 111 and the second column 112 are provided with a vertex 130. Each vertex 130 includes a first vertex portion 131 and a second vertex portion 132, and the first vertex portion 131 and the second vertex portion 132 are connected to each other and are arranged at an angle. Both the first vertex portion 131 and the second vertex portion 132 are provided with a first pivoting portion Q1, and the first pivoting portion Q1 is used to pivot with the first pivoting end 1221A of the first handrail tube 122.

[0166] Continue to see Figure 5 and Figure 6In some embodiments, a sliding member 140 is slidably provided on the first column 111 and the second column 112. The sliding member 140 can slide up and down on the first column 111 and the second column 112. Each sliding member 140 includes a first sliding portion 141 and a second sliding portion 142, which are connected to each other and arranged at an angle. The first sliding portion 141 and the second sliding portion 142 are both provided with a second pivoting portion Q2, and the second pivoting portion Q2 is used to pivot with the first sliding end 1221B of the first handrail tube 122. When each first armrest tube group 121 switches from the extended position to the folded position, the sliding member 140 located on each first column 111 and each second column 112 moves downward (F1 direction) along the corresponding first column 111 and second column 112, and at the same time, the first sliding end 1221B of each first armrest tube 122 pivots relative to the second pivot portion Q2 of the sliding member 140, and the first pivot end 1221A of each first armrest tube 122 pivots relative to the first pivot portion Q1 of the top angle 130, so that each first column 111 and each second column 112 can be brought closer to each other, so that the bed frame 10 is switched from the extended state to the folded state. When each first armrest tube group 121 switches from the folded position to the extended position, the sliding members 140 located on each first column 111 and each second column 112 move upward (F2 direction) along the corresponding first column 111 and second column 112, and at the same time, the first sliding end 1221B of each first armrest tube 122 pivots relative to the second pivot portion Q2 of the sliding member 140, and the first pivot end 1221A of each first armrest tube 122 pivots relative to the first pivot portion Q1 of the vertex 130, so that each first column 111 and each second column 112 can move away from each other, so that the bed frame 10 can be switched from the folded state to the extended state.

[0167] See also Figure 6 and Fig. 9 In some embodiments, the top corner 130 is provided with a locking mechanism 150. When the armrest tube mechanism 120 is in the unfolded position, the locking mechanism 150 can be locked with the sliding member 140 to limit the sliding of the sliding member 140 relative to the column 110, so that the bed frame 10 remains in the unfolded state.

[0168] Continue to see Figure 6 and Fig. 9In some embodiments, the locking mechanism 150 includes a locking member 151 pivotally connected to the top corner 130. Specifically, the top corner 130 has a support seat 133, and the locking member 151 is pivotally connected to the support seat 133. The locking member 151 has an operating end 1511 and a locking end 1512, and the sliding member 140 is provided with a locking matching portion 143. The locking member 151 can pivot between a locking position and a release position. When the locking member 151 is located at the locking position, the locking end 1512 can be locked and matched with the locking matching portion 143. When the locking member 151 is located at the release position, the locking end 1512 can be released from the locking matching portion 143. More specifically, the pivot point between the locking member 151 and the support seat 133 is located between the operating end 1511 and the locking end 1512, so that the locking member 151 is roughly in a "seesaw" structure when pivoting on the support seat 133, that is, the operating end 1511 is pressed and rotated to make the operating end 1511 close to the center of the first column 111 or the second column 112, so that when the locking member 151 rotates, the locking end 1512 is tilted away from the center of the first column 111 or the second column 112. Of course, the locking member 151 can also be configured to pull the operating end 1511 to release the locking end 1512 from the locking mating portion 143.

[0169] Further, see Fig. 9 In some embodiments, the locking mechanism 150 further includes a reset member 152. The operating end 1511 can be operated to pivot the locking member 151 from the locked position to the unlocked position, and the reset member 152 is used to bias the operating end 1511 to pivot the locking member 151 to the locked position. The reset member 152 is, for example, a spring, which abuts against the operating end 1511 and provides a reset force for the operating end 1511 to move away from the center of the first column 111 or the second column 112. When the user needs to switch the locking member 151 from the locked position to the unlocked position, the user only needs to press the operating end 1511, and the locking end 1512 will tilt away from the center of the first column 111 or the second column 112, so that the locking end 1512 can be separated from the locking mating portion 143. Under the action of the reset member 152, the user only needs to release the operating end 1511 to switch the locking member 151 from the unlocked position to the locked position.

[0170] Optionally, in other embodiments, the support base 133 may be omitted, and the locking member 151 is directly pivoted to the top corner 130 (see FIG. Fig.32). Specifically, a mounting seat 134 is provided on the top corner 130, and a pressing channel 1341 is provided in the mounting seat 134. The operating end 1511 of the locking member 151 extends into the mounting seat 134 and is accommodated in the pressing channel 1341. More specifically, the pressing channel 1341 passes through the mounting seat 134 along its length direction, and a button 153 is movably provided in the pressing channel 1341, and the button 153 is located on the side of the operating end 1511 facing away from the column 110, and is against the operating end 1511. In this way, the user can directly push the operating end 1511 to rotate around the pivot point between the locking member 151 and the top corner 130 by pressing the button 153 horizontally, so that the locking end 1512 is tilted to disengage from the locking mating portion 143. In this way, the user only needs to press the button 153 horizontally to drive the locking member 151 to rotate, without pressing and rotating the operating end 1511, and the operation is more convenient and quick.

[0171] Of course, in some alternative embodiments, the implementation of the locking mechanism 150 is not limited to the above examples, as long as it can play the role of locking the sliding member 140.

[0172] See also Figures 5 to 9 In some embodiments, the first handrail tube group 121 further includes a rotating connection mechanism 123. The two first handrail tubes 122 are pivotally connected by the rotating connection mechanism 123. Specifically, when the first handrail tube group 121 includes two first handrail tubes 122, the two first handrail tubes 122 are rotationally connected by the rotating connection mechanism 123. When the sliding member 140 corresponding to one of the first handrail tubes 122 moves downward on the first column 111 or the second column 112, the first sliding end 122B of the first handrail tube 122 moves downward, so that the first handrail tube 122 is tilted and has a tendency to move downward. At this time, the rotating connection mechanism 123 also moves downward under the drive of the first handrail tube 122. Under the action of the rotating connection mechanism 123, the other first handrail tube 122 can also be driven to have a tendency to move downward, so that the sliding member 140 corresponding to the other first handrail tube 122 can move downward relative to the second column 112 or the first column 111. It can be seen that the rotating connection mechanism 123 has a linkage effect, which can make the two first armrest tubes 122 between the adjacent first columns 111 and the second columns 112 rotate synchronously. By setting the rotating connection mechanism 123, the user can only push or pull a single sliding member 140 downward to make all the armrest tube mechanisms 120 fold up, thereby realizing the folding of the entire child bed 1000.

[0173] Specifically, the rotating connection mechanism 123 is connected to the first tube segments 1222 of the two first handrail tubes 122, and when the two first handrail tubes 122 are in the unfolded position, the two first tube segments 1222 have an overlapping area. Further, when the handrail tube mechanism 120 is in the unfolded position, that is, when the two first handrail tubes 122 are in the unfolded position, the rotating connection mechanism 123 is located below each first tube segment 1222. In this way, it is possible to avoid the rotating connection mechanism 123 being protruding above the horizontal plane where the first handrail tubes 122 are located, causing problems such as the child bed cover 1200 not fitting well.

[0174] It should be noted that “when the handrail tube mechanism 120 is in the unfolded position, the rotating connection mechanism 123 is located below each first tube segment 1222” means that when the handrail tube mechanism 120 is in the unfolded position, along the first connection portion 12311 (see Figure 7 ) and the second connecting portion 12312 (see Figure 7 ) From the perspective of the setting direction on the rotating connection mechanism 123, the height of the end of the rotating connection mechanism 123 where the first connection part 12311 is located is lower than the height of the upper surface of the first tube segment 1222. In other words, the end of the rotating connection mechanism 123 where the first connection part 12311 is located will not protrude from the horizontal plane where the upper surface of the first tube segment 1222 is located, thereby improving the fit of the children's bed covering 1200 on the armrest tube mechanism 120.

[0175] See also Figures 6 to 8 In some embodiments, the rotating connection mechanism 123 includes a rotating member 1231. Two rotating members 1231 are provided, and each rotating member 1231 is provided with a first connecting portion 12311 and a second connecting portion 12312. Each first handrail tube 122 corresponds to the first connecting portion 12311 connected to each rotating member 1231, and the two second connecting portions 12312 are rotatably connected. When the two first handrail tubes 122 in the first handrail tube group 121 are in the unfolded position, the two rotating members 1231 are overlapped with each other; when the two first handrail tubes 122 in the first handrail tube group 121 are switched from the unfolded position to the folded position, the two rotating members 1231 rotate with each other through the second connecting portion 12312 to form a certain angle. Specifically, when the first column 111 and the second column 112 are close to each other, the angle between the two rotating members 1231 gradually increases.

[0176] Specifically, in some embodiments, Fig.10 As shown, the rotating member 1231 includes a first clamping plate 12313, a connecting plate 12314 and a second clamping plate 12315. The connecting plate 12314 is connected between the first clamping plate 12313 and the second clamping plate 12315, and the first clamping plate 12313, the connecting plate 12314 and the second clamping plate 12315 are surrounded to form a clamping groove 12316 (see Fig.10) so that the rotating member 1231 is generally in a U-shaped structure. The first clamping plate 12313 and the second clamping plate 12315 are both provided with a first connecting portion 12311 and a second connecting portion 12312, and the first connecting portion 12311 is closer to the notch of the clamping groove 12316 than the second connecting portion 12312. The first handrail tube 122 is limited in the clamping groove 12316 and connected to the two first connecting portions 12311. More specifically, the first connecting portion 12311 and the second connecting portion 12312 are both limiting holes. The first handrail tube 122 is placed in the clamping groove 12316, and is connected to the first handrail tube 122 through the limiting hole (first connecting portion 12311) through a connecting member such as a screw or a bolt, so that the first handrail tube 122 can be stably installed on the rotating member 1231. Furthermore, the two rotating members 1231 can be rotatably connected by a rotating shaft or the like penetrating the limiting hole (second connecting portion 12312).

[0177] See also Fig.10 In some embodiments, the rotating member 1231 further includes a reinforcing rib 12317. The first clamping plate 12313 and the second clamping plate 12315 are both provided with a reinforcing rib 12317, and the reinforcing rib 12317 on the first clamping plate 12313 extends toward the second clamping plate 12315, and the reinforcing rib 12317 on the second clamping plate 12315 extends toward the first clamping plate 12313. By adding the reinforcing rib 12317, the structural strength of the rotating member 1231 can be improved as a whole. In addition, the end of each reinforcing rib 12317 close to the notch of the clamping groove 12316 can be used to support the first handrail tube 122 (see Figure 7 ).

[0178] See also Fig.11 and Fig.12 In some alternative embodiments, the rotating connection mechanism 123 includes two rotating connection parts 1232, each of which includes a clamping plate 12321 and a connecting column 12322 fixed on the clamping plate 12321. The clamping plate 12321 is provided with a first connecting part 12311, and the two first handrail tubes 122 are respectively connected to the first connecting parts 12311 of the two rotating connection parts 1232, and are pivotally connected through the connecting columns 12322 of the two rotating connection parts 1232.

[0179] Continue to see Fig.11 and Fig.12, the clamping plates 12321 of the two rotating connecting parts 1232 and the connecting columns 12322 of the two rotating connecting parts 1232 enclose a clamping groove 12316. The two first handrail tubes 122 are limited in the clamping groove 12316 and connected to the corresponding first connecting parts 12311. Alternatively, one of the two first handrail tubes 122 is located in the clamping groove 12316 and connected to the corresponding first connecting part 12311, and the other is located outside the clamping groove 12316 and connected to the corresponding first connecting part 12311. Alternatively, both of the two first handrail tubes 122 are located outside the clamping groove 12316 and connected to the corresponding first connecting part 12311.

[0180] See also Fig.13 and Fig.14 In some embodiments, the bed frame 10 further includes a first protection component 160. Specifically, the first protection component 160 is disposed on the first handrail tube 122 and is located at the pivot point of the two first handrail tubes 122, that is, it is equivalent to being located at the connection point between the first handrail tube 122 and the rotating connection mechanism 123. When the handrail tube mechanism 120 switches from the unfolded position to the folded position, the two first handrail tubes 122 pivot relative to the rotating connection mechanism 123 respectively, and enclose the rotating connection mechanism 123 to form a first shearing clamping area 127 (see Figure 8 The first protection component 160 is used to shield the first shearing and clamping area 127 (see Figure 8 and Fig.14 In this way, when the user folds the bed frame 10, not only can the child bed covering 1200 be prevented from entering the first shearing and clamping area 127, thereby avoiding affecting the folding smoothness of the bed frame 10, but also the user's hand can be prevented from accidentally entering the first shearing and clamping area 127, thereby preventing possible pinching injuries.

[0181] In one embodiment, at least one of the two first handrail tubes 122 between the first column 111 and the second column 112 is provided with a first protection assembly 160. In other words, any one of the first handrail tubes 122 may be provided with the first protection assembly 160, or both of the first handrail tubes 122 may be provided with the first protection assembly 160.

[0182] See also Fig.14 and Fig.15In some embodiments, the first protective assembly 160 includes a first protective baffle 161 and a first protective connector 162 connected to each other. The first protective baffle 161 is used to shield the first shearing and stuffing area 127. In this embodiment, the first protective baffle 161 is generally a trapezoidal sheet structure, and the first protective connector 162 is arranged at a bottom edge of the first protective baffle 161. In this embodiment, the first protective baffle 161 and the first protective connector 162 are integrally formed. In other embodiments, the first protective baffle 161 and the first protective connector 162 can also be connected by riveting, welding, etc. A first arc-shaped concave surface 1621 that can fit the outer wall of the first handrail tube 122 is formed on the side of the first protective connector 162 facing away from the first protective connector 162. In this embodiment, two first connecting protrusions are arranged at intervals on one side of the first arc-shaped concave surface 1621, and each first connecting protrusion is provided with a first connecting hole 1622. In other embodiments, the number of the first connecting protrusions and the first connecting holes 1622 can also be more than two or less than two. The corresponding first handrail tube 122 is provided with two first fixing holes (not shown in the drawings) respectively corresponding to the two first connection holes 1622, and two fasteners (such as rivets, screws or rivets, etc.) respectively pass through the corresponding first connection holes 1622 and the first fixing holes to connect the first protective assembly 160 and the first handrail tube 122. In this way, the stability of the first protective assembly 160 after installation can be improved. Of course, in other alternative embodiments, the first protective assembly 160 can also be connected to the first handrail tube 122 by a snap-on method, or the first protective assembly 160 can also be integrally formed on the first handrail tube 122.

[0183] Fig.16 FIG. 1 shows a three-dimensional view of a bed frame 10 provided according to a second embodiment of the present application. The bed frame 10 is similar to the first embodiment and includes a first column 111, a second column 112 and an armrest tube mechanism 120. The second column 112 is arranged opposite to the first column 111. The armrest tube mechanism 120 is movably connected between the first column 111 and the second column 112. The armrest tube mechanism 120 is in the unfolded position (see 16 and Fig.17 ) and the collapsed position (see Fig.19 When the armrest tube mechanism 120 is in the unfolded position, the armrest tube mechanism 120 is at least partially parallel to the horizontal plane.

[0184] Compare the bed frame 10 of the first embodiment with the bed frame 10 of the second embodiment (see Figure 5 and Fig.16 ) It can be seen that the armrest tube mechanism 120 of the bed frame 10 in the second embodiment is different from the armrest tube mechanism 120 of the bed frame 10 in the first embodiment.

[0185] See also Fig.16In some embodiments, the handrail tube mechanism 120 includes a second handrail tube group 124, and the second handrail tube group 124 includes a second handrail tube 125 and a third handrail tube 126, and two of the second handrail tube 125 and two of the third handrail tube 126 are provided. Fig.17 Each second handrail tube 125 has a second pivot end 1251A and a second sliding end 1251B, the two second pivot ends 1251A are pivotally connected, and the two second sliding ends 1251B are slidably disposed on the first column 111 and the second column 112, respectively, and are pivotally connected to the first column 111 and the second column 112. Each third handrail tube 126 has a third pivot end 1261A and a fourth pivot end 1261B, the two third pivot ends 1261A are pivotally connected, and the two fourth pivot ends 1261B are pivotally connected to the first column 111 and the second column 112, respectively. When the handrail tube mechanism 120 is in the unfolded position, at least a portion of each second handrail tube 125 and at least a portion of each third handrail tube 126 are parallel to the horizontal plane. Therefore, when the armrest tube mechanism 120 is in the unfolded position, the crib cover 1200 (such as a cloth cover) installed on the armrest tube mechanism 120 tends to be flat, so that it fits better with the armrest tube mechanism 120, thereby making the bed frame 10 covered with the crib cover 1200 look neater.

[0186] See also Fig.18 In some embodiments, the second handrail tube 125 includes a third tube segment 1252 and a fourth tube segment 1253 connected and arranged at an angle, the first end of the third tube segment 1252 away from the fourth tube segment 1253 is a second pivot end 1251A, and the first end of the fourth tube segment 1253 away from the third tube segment 1252 is a second sliding end 1251B. At the same time, the third handrail tube 126 includes a fifth tube segment 1262 and a sixth tube segment 1263 connected and arranged at an angle, the first end of the fifth tube segment 1262 away from the sixth tube segment 1263 is a fourth pivot end 1261B, and the first end of the sixth tube segment 1263 away from the fifth tube segment 1262 is a third pivot end 1261A. When the handrail tube mechanism 120 is in the deployed position, each third tube segment 1252 and each fifth tube segment 1262 are located in the same horizontal plane, and the fourth tube segment 1253 extends downward from the second end of the third tube segment 1252, and the sixth tube segment 1263 extends downward from the second end of the fifth tube segment 1262. The second handrail tube 125 and the third handrail tube 126 connected to the first column 111 or the second column 112 are arranged side by side in the horizontal direction, and the projections of the fifth tube segment 1262 and the third tube segment 1252 on the vertical plane parallel to the front-back direction (BP direction) and perpendicular to the horizontal plane overlap.

[0187] Combine the following Fig.16 and Fig.18, to explain the meaning of the above-mentioned "the second handrail tube 125 and the third handrail tube 126 connected to the first column 111 or the second column 112 are arranged side by side in the horizontal direction and the projections of the fifth tube segment 1262 and the third tube segment 1252 on the vertical plane parallel to the front-to-back direction and perpendicular to the horizontal plane partially overlap."

[0188] Fig.16 The schematic diagram shows a bed frame 10 in this embodiment, which includes two first columns 111, two second columns 112 and an armrest tube mechanism 120. When the bed frame 10 is in the unfolded state, the bed frame 10 is generally in a square structure, and is generally symmetrical left-right and front-back. In this embodiment, one of the first columns 111 and the second column 112 arranged in the front-to-back direction can be taken as an example. When the two second armrest tubes 125 and the two third armrest tubes 126 arranged therebetween are in the unfolded position, the second armrest tubes 125 and the third armrest tubes 126 are arranged side by side in the horizontal direction (specifically, they can be regarded as being in the left-right direction), and the third tube segment 1252 of the second armrest tube 125 and the fifth tube segment 1262 of the third armrest tube 126 are partially overlapped in the left-right direction (see FIG. 1 ). Fig.16 and Fig.18 ).

[0189] See also Fig.16 and Fig.18 In some embodiments, the second pivoting ends 1251A of the two third tube segments 1252 are arranged side by side in the horizontal direction and their projections on the vertical plane parallel to the front-to-back direction and perpendicular to the horizontal plane partially overlap. Specifically, taking one of the first upright column 111 and the second upright column 112 arranged along the front-to-back direction as an example, when the two second handrail tubes 125 arranged between the two are in the unfolded position, the second pivoting ends 1251A corresponding to the two third tube segments 1252 are arranged side by side in the horizontal direction (specifically, it can be regarded as in the left-right direction), and the second pivoting ends 1251A corresponding to the two third tube segments 1252 partially overlap in the left-right direction.

[0190] In some embodiments, the angle α between the third tube segment 1252 and the fourth tube segment 1253 is greater than 90°.

[0191] More specifically, in some embodiments, the angle α between the third tube segment 1252 and the fourth tube segment 1253 is 150°. Of course, in some alternative embodiments, the angle α between the third tube segment 1252 and the fourth tube segment 1253 can also be 100°, 120° or 140°, etc., which is not specifically limited here.

[0192] In some embodiments, the angle α (not shown) between the fifth tube segment 1262 and the sixth tube segment 1263 is greater than 90°.

[0193] More specifically, in some embodiments, the angle α between the fifth tube segment 1262 and the sixth tube segment 1263 is 150°. Of course, in some alternative embodiments, the angle α between the fifth tube segment 1262 and the sixth tube segment 1263 can also be 100°, 120°, or 140°, etc., which is not specifically limited here.

[0194] See also Fig.16 and Fig.18 The second handrail tube group 124, for example, further includes the rotating connection mechanism 123 described in the first embodiment. Specifically, the rotating connection mechanism 123 is connected to the second handrail tube 125 and the third handrail tube 126. In this embodiment, two rotating connection mechanisms 123 are provided in one second handrail tube group 124, and along the parallel direction of the second handrail tube 125 and the third handrail tube 126, the second handrail tube 125 and the third handrail tube 126 that are arranged opposite to each other are connected by a rotating connection mechanism 123.

[0195] See also Fig.16 In some embodiments, the bed frame 10 further includes the top corner 130 and the sliding member 140 described in the first embodiment, and the top corner 130 has a locking mechanism 150. Referring to the contents described in the first embodiment, each first column 111 and each second column 112 is provided with a top corner 130 and a sliding member 140.

[0196] Specifically, the vertex 130 includes a first vertex portion 131 and a second vertex portion 132, the first vertex portion 131 and the second vertex portion 132 are connected to each other and are arranged at an angle, and the first vertex portion 131 and the second vertex portion 132 are both provided with a first pivoting portion Q1, and the first pivoting portion Q1 is pivotally connected to the fourth pivoting end 1261B. Specifically, the sliding member 140 includes a first sliding portion 141 and a second sliding portion 142, the first sliding portion 141 and the second sliding portion 142 are connected to each other and are arranged at an angle, and the first sliding portion 141 and the second sliding portion 142 are both provided with a second pivoting portion Q2, and the second pivoting portion Q2 is pivotally connected to the second sliding end 1251B.

[0197] When the bed frame 10 of this embodiment is used, when the user needs to switch the bed frame 10 from the unfolded state to the folded state, that is, when the armrest tube mechanism 120 is switched from the unfolded position to the folded position (by Fig.17 The displayed status switches to Fig.19 Its working process can be described by the handrail tube mechanism 120 arranged between a first column 111 and a second column 112.

[0198] See also Figures 17 to 19, the user pushes or pulls the sliding member 140, so that the sliding member 140 drives the second sliding end 1251B of the corresponding second handrail tube 125 to move downward (F1 direction) on the corresponding first column 111 and second column 112. Since in the unfolded state, each third tube segment 1252 is arranged horizontally, the fourth tube segment 1253 extends downward from the second end of the third tube segment 1252, the fifth tube segment 1262 is arranged horizontally, and the sixth tube segment 1263 extends downward from the second end of the fifth tube segment 1262, therefore, when the second sliding end 1251B moves downward with the sliding member 140, the second handrail tube 125 pivots, and the two second pivoting ends 1251A rotate relative to each other, so that the two second handrail tubes 125 are close to each other. At the same time, the rotating connection mechanism 123 moves downward with the second handrail tube 125. Under the linkage of the rotating connection mechanism 123, the third handrail tube 126 has a tendency to rotate downward relative to the corresponding vertex angle 130, and the two third pivot ends 1261A rotate with each other to make the two third handrail tubes 126 approach each other, and finally achieve the first column 111 and the second column 112 to move closer to each other. By setting the rotating connection mechanism 123, the user can only push or pull a single sliding member 140 downward to make all the handrail tube mechanisms 120 folded, thereby achieving the folding of the entire child bed 1000.

[0199] When the bed frame 10 of this embodiment is used, when the user needs to switch the bed frame 10 from the folded state to the unfolded state, that is, when the armrest tube mechanism 120 is switched from the folded position to the unfolded position (by Fig.19 The displayed status switches to Fig.17 Its working process can also be described by the handrail tube mechanism 120 arranged between a first column 111 and a second column 112.

[0200] See also Fig.19 , the user pushes the sliding member 140, so that the sliding member 140 drives the second sliding end 1251B of the second handrail tube 125 to move upward along the corresponding first column 111 and second column 112. At this time, the two second handrail tubes 125 move away from each other and push the first column 111 and second column 112 away from each other. In this process, the fourth pivoting ends 1261B of the two third handrail tubes 126 rotate upward relative to the first pivoting portion Q1, and the two third handrail tubes 126 move away from each other and also push the first column 111 and second column 112 away from each other. When the two second handrail tubes 125 and the two third handrail tubes 126 are fully unfolded, the sliding member 140 can be locked on the first column 111 and the second column 112 through the locking mechanism 150.

[0201] See also Figure 20 to Figure 22 The bed frame 10 provided in the second embodiment may further include a second protection component 170. Fig. 20The partial structure of the bed frame 10 is shown, at this time, the second armrest tube set 124 is in the unfolded position; Fig.21 Shown Fig. 20 The bed frame 10 is in the middle, and the second armrest tube group 124 is in a transition position between the unfolded position and the folded position; Fig. 22 It shows Fig. 20 The bed frame 10 is in the folded position, and the second handrail tube group 124 is in the folded position. In the present embodiment, the second protective assembly 170 is disposed on each second handrail tube 125 and / or the third handrail tube 126. In other words, the second protective assembly 170 can be disposed only on each second handrail tube 125; or, only on each third handrail tube 126; or, can be disposed on both the second handrail tube 125 and the third handrail tube 126. Further, the second protective assembly 170 is located at the pivot joint of the second handrail tube 125 and the third handrail tube 126 connected to the first column 111 or the second column 112, that is, it is equivalent to being located at the connection between the second handrail tube 125 and the rotating connection mechanism 123; and / or the connection between the third handrail tube 126 and the rotating connection mechanism 123. When the handrail tube mechanism 120 switches from the extended position to the retracted position, the second handrail tube 125 and the third handrail tube 126 connected to the first column 111 or the second column 112 respectively pivot relative to the corresponding rotating connection mechanism 123 and enclose the corresponding rotating connection mechanism 123 to form a second shearing clamping area 128 (see Fig.19 ), the second protection assembly 170 is used to shield the second shearing and clamping area 128 (see Fig.19 and Fig. 22 In this way, when the user folds the bed frame 10, not only can the child bed cover 1200 be prevented from entering the second shearing and clamping area 128, thereby avoiding affecting the folding smoothness of the bed frame 10, but also the user's hand can be prevented from accidentally entering the second shearing and clamping area 128, thereby preventing possible pinching injuries.

[0202] like Fig.19 As shown, when the handrail tube mechanism 120 switches from the unfolded position to the folded position, the two sixth tube segments 1263 pivot with each other and gradually enclose to form a third shearing and clamping area 129. Specifically, this refers to the area enclosed by the inner sides of the two sixth tube segments 1263. Specifically, as Figure 20 to Figure 22 As shown, in this embodiment, the second protection assembly 170 is disposed on each third handrail tube 126, and when the second protection assembly 170 is disposed on each third handrail tube 126, the second protection plate 170 extends from the fifth tube section 1262 to the sixth tube section 1263, so that the second protection assembly 170 is also used to shield the third shearing clamping area 129 (see Fig.19 and Fig. 22In this way, not only can the child bed cover 1200 be prevented from entering the third shearing trap 129 , but also the hand can be prevented from accidentally entering the third shearing trap 129 .

[0203] Specifically, Fig.23 As shown, in the second embodiment, the second protection assembly 170 of the bed frame 10 includes a second protection baffle 171 and a second protection connector 172 connected to each other. The second protection baffle 171 is used to shield the second shearing and stuffing area 128 and the third shearing and stuffing area 129. In this embodiment, the second protection baffle 171 is generally a trapezoidal sheet structure, and the second protection connector 172 is arranged at the bottom edge and the side edge of one side of the second protection baffle 171. In this embodiment, the second protection baffle 171 and the second protection connector 172 are integrally formed. In other embodiments, the second protection baffle 171 and the second protection connector 172 can also be connected by riveting, welding, etc. A second arc-shaped concave surface 1721 that can fit the outer wall of the second handrail tube 125 and / or the third handrail tube 126 is formed on the side of the second protection baffle 171 facing away from the second protection baffle 171. In this embodiment, two second connection protrusions are arranged at intervals on one side of the second arc-shaped concave surface 1721, and each second connection protrusion is provided with a second connection hole 1722. In other embodiments, the number of the second connection protrusions and the second connection holes 1722 may be more than two or less than two. The corresponding second handrail tube 125 and / or the third handrail tube 126 are provided with two second fixing holes (not shown in the drawings) respectively opposite to the two second connection holes 1722, and two fasteners (such as rivets, screws or rivets, etc.) respectively pass through the corresponding second connection holes 1722 and the second fixing holes to connect the second protective assembly 170 and the second handrail tube 125 and / or the third handrail tube 126. In this way, the stability of the second protective assembly 170 after installation can be improved. Of course, the second protective plate 170 can also be installed on the second handrail tube 125 and / or the third handrail tube 126 in other ways, such as snap-on connection, etc., which are not specifically limited here.

[0204] like Fig.17 and Fig.18 As shown, when the handrail tube mechanism 120 switches between the unfolded position and the folded position, the two sixth tube segments 1263 pivot with each other and gradually enclose to form a third shearing clamping area 129. Specifically, it refers to the area enclosed by the outer sides of the two sixth tube segments 1263. Optionally, in other alternative embodiments, the second protective baffle 171 of the second protective assembly 170 can also be in other shapes. For example, the second protective baffle 171 is a roughly rectangular sheet structure. Fig. 27 and Fig.28As shown, in one embodiment, the second protective baffle 171 includes a first plate 1711 and a second plate 1712 connected to each other. The first plate 1711 is roughly a right-angled trapezoidal sheet structure, the second plate 1712 is roughly a triangular sheet structure, and the second plate 1712 is arranged at the oblique side edge of the first plate 1711, so that the entire second protective baffle 171 is roughly rectangular. Figure 24 to Figure 26 As shown, when the second protective baffle 171 is installed on each third handrail tube 126, the first plate body 1711 can be used to shield the second shear clamping area 128 and the third shear clamping area 129 at the same time, and the third shear clamping area 129 is always shielded, that is, it is equivalent to that both the third shear clamping area 129 on the inner side of the sixth tube section 1263 and the third shear clamping area 129 on the outer side of the sixth tube section 1263 will be shielded (see Fig.18 , Fig.19 , Fig. 22 and Fig.26 ). Specifically, Fig. 27 and Fig.28 As shown, an arc groove 1713 is formed at the connection between the first plate 1711 and the second plate 1712. The arc groove 1713 is used to adapt to the sixth pipe segment 1263 and play a role of avoidance, so that after the second protective baffle 171 is installed on the third handrail tube 126, the first plate 1711 and the second plate 1712 can be in the same vertical plane to respectively block the third shearing clamping area 129 inside the sixth pipe segment 1263 and the third shearing clamping area 129 outside the sixth pipe segment 1263. Specifically, a second connecting hole 1722 is formed on the groove wall of the arc groove 1713 and the first plate 1711, respectively, and two fasteners (such as rivets, screws or rivets, etc.) pass through the corresponding second connecting holes 1722 to connect with the sixth pipe segment 1263 and the rotating connection mechanism 123 (such as the rotating member 1231 or the clamping plate 12321) to connect the second protective assembly 170 with the third handrail tube 126.

[0205] It should be noted that the "inside" of the sixth pipe segment 1263 refers to the side of the sixth pipe segment 1263 that faces the angle formed between the sixth pipe segment 1263 and the fifth pipe segment 1262 that is less than 180 degrees; the "outside" of the sixth pipe segment 1263 refers to the side of the sixth pipe segment 1263 that faces away from the angle formed between the sixth pipe segment 1263 and the fifth pipe segment 1262 that is less than 180 degrees. In other words, the "inside" of the sixth pipe segment 1263 refers to the side of the sixth pipe segment 1263 that faces away from the angle formed between the sixth pipe segment 1263 and the fifth pipe segment 1262 that is less than 180 degrees. Fig.24 The lower side of the sixth pipe section 1263 in the unfolded state of the handrail tube mechanism shown in FIG. 1264; the “outer side” of the sixth pipe section 1263 refers to the lower side of the sixth pipe section 1263 in the unfolded state of the handrail tube mechanism shown in FIG. Fig.24The upper side of the sixth pipe section 1263 of the handrail tube mechanism in the unfolded state shown. Optionally, in some alternative embodiments, the handrail tube mechanism 120 includes a second handrail tube group 124, and the second handrail tube group 124 may only include two of the above-mentioned second handrail tubes 125. Each second handrail tube 125 has a second pivot end 1251A and a second sliding end 1251B, the two second pivot ends 1251A are pivotally connected, and the two second sliding ends 1251B are slidably disposed on the first column 111 and the second column 112, respectively, and are pivotally connected to the first column 111 and the second column 112. When the handrail tube mechanism 120 is in the unfolded position, at least a portion of each second handrail tube 125 is parallel to the horizontal plane.

[0206] Optionally, in some other alternative embodiments, the handrail tube mechanism 120 includes a second handrail tube group 124, and the second handrail tube group 124 may include only two of the above-mentioned third handrail tubes 126. Each third handrail tube 126 has a third pivot end 1261A and a fourth pivot end 1261B, the two third pivot ends 1261A are pivotally connected, and the two fourth pivot ends 1261B are respectively pivotally connected to the first column 111 and the second column 112. When the handrail tube mechanism 120 is in the unfolded position, at least a portion of each third handrail tube 126 is parallel to the horizontal plane.

[0207] Fig.29 A three-dimensional view of a bed frame 10 provided according to the third embodiment of the present application is shown, and the bed frame 10 is similar to the first embodiment or the second embodiment described above. The bed frame 10 includes a plurality of columns 110 (which can be regarded as the first column 111 and the second column 112 in the first embodiment or the second embodiment) and a plurality of armrest tube mechanisms 120. More specifically, the plurality of columns 110 are arranged at intervals along the circumferential direction, and an armrest tube mechanism 120 is movably connected between two adjacent columns 110. The armrest tube mechanism 120 is switchable between an extended position and a folded position so that the bed frame 10 can be switched between an extended state and a folded state. When the armrest tube mechanism 120 is in the extended position, the armrest tube mechanism 120 is at least partially parallel to the horizontal plane. Among them, when the bed frame 10 is in the extended state, the plurality of columns 110 are away from each other (see Fig.17 ); When the bed frame 10 is in the folded state, the plurality of uprights 110 are folded together.

[0208] In some examples of the third embodiment, the handrail tube mechanism 120 includes at least one of a first handrail tube group 121 and a second handrail tube group 124 .

[0209] Specifically, in Fig.29The bed frame 10 in the third embodiment shown includes both a first armrest pipe group 121 and a second armrest pipe group 124. Specifically, the first armrest pipe group 121 may refer to the first armrest pipe group 121 in the bed frame 10 provided in the first embodiment, and the second armrest pipe group 124 may refer to the second armrest pipe group 124 in the bed frame 10 provided in the second embodiment.

[0210] In some embodiments, Fig.29 As shown, the bed frame 10 includes four columns 110 arranged at intervals along the circumferential direction. In order to clearly understand the handrail tube mechanism 120 arranged between each column 110, the four columns 110 can be referred to as the first column 111, the second column 112, the third column 113 and the fourth column 114 in sequence. Among them, a first handrail tube group 121 is provided between the first column 111 and the second column 112, and between the third column 113 and the fourth column 114, and the two first handrail tube groups 121 are arranged oppositely. A second handrail tube group 124 is provided between the first column 111 and the fourth column 114, and between the second column 112 and the third column 113, and the two second handrail tube groups 124 are arranged oppositely. When the bed frame 10 is in the unfolded state, it generally has a rectangular structure.

[0211] See also Fig.29 In some embodiments, the first column 111, the second column 112, the third column 113, and the fourth column 114 are all provided with a vertex 130 and a sliding member 140. The vertex 130 includes a first vertex portion 131 and a second vertex portion 132, the first vertex portion 131 and the second vertex portion 132 are connected to each other and are arranged at an angle, and the first vertex portion 131 and the second vertex portion 132 are both provided with a first pivoting portion Q1. Specifically, one first pivoting portion Q1 is pivoted to the first pivoting end 1221A of the first handrail tube 122, and the other first pivoting portion Q1 is pivoted to the fourth pivoting end 1261B of the third handrail tube 126.

[0212] Continue to see Fig.29 In some embodiments, the sliding member 140 includes a first sliding portion 141 and a second sliding portion 142, which are connected to each other and arranged at an angle. The first sliding portion 141 and the second sliding portion 142 are both provided with a second pivoting portion Q2. Specifically, one second pivoting portion Q2 is pivotally connected to the first sliding end 1221B of the first handrail tube 122, and the other second pivoting portion Q2 is pivotally connected to the second sliding end 1251B of the second handrail tube 125.

[0213] See also Fig.30Further, in the third embodiment, the bed frame 10 includes both a first protection component 160 and a second protection component 170. Specifically, the structure and setting position of the first protection component 160 can refer to the first protection component 160 in the bed frame 10 provided in the first embodiment; the structure and setting position of the second protection component 170 can refer to the second protection component 170 in the bed frame 10 provided in the second embodiment, and will not be repeated here.

[0214] It should be noted that in the third embodiment, the second protective baffle 171 in the second protective assembly 170 may be in the aforementioned trapezoidal sheet structure (see Fig.23 and Fig.30 ); Of course, it can also be the aforementioned rectangular sheet structure (see Fig. 27 and Fig.31 ).

[0215] See also Fig.33 and Fig.34 The fourth embodiment of the present application also provides a bed frame 10, which is a variation of the bed frame 10 shown in the first embodiment, and includes: a plurality of columns 110 and a plurality of handrail tube mechanisms 120. The plurality of columns 110 are arranged at intervals along the circumferential direction, and a handrail tube mechanism 120 is movably connected between each two adjacent columns 110. The handrail tube mechanism 120 includes at least one pair of handrail tubes, and a pair of handrail tubes includes two handrail tubes, and the two handrail tubes are intersected and pivotally connected to each other, and each handrail tube mechanism 120 can be switched between an extended position and a folded position so that the bed frame 10 can be switched between an extended state and a folded state.

[0216] It should be noted that the "pair of handrail tubes" in the fourth embodiment may refer to two first handrail tubes 122, but it should be emphasized that the two first handrail tubes 122 are straight tubes, which is equivalent to the first tube section 1222 and the second tube section 1223 being on the same straight line. In addition, compared with the bed frame 10 in the first embodiment, the bed frame 10 in the fourth embodiment omits the rotating connection mechanism 123, which is equivalent to when two first handrail tubes 122 are provided between the two columns 110, the two first handrail tubes 122 are directly pivoted instead of being pivoted through the rotating connection mechanism 123.

[0217] For further information, see Fig.35 and Fig.36 , the bed frame 10 in the fourth embodiment further includes a plurality of third protection components 180. Specifically, each pair of handrail tubes is provided with a third protection component 180, and the third protection component 180 is installed on at least one handrail tube and is located at the pivot point of the two handrail tubes. When each handrail tube mechanism 120 switches between the unfolded position and the folded position, each third protection component 180 is used to shield the fourth shearing and filling area α1 (see FIG. 1 ) formed between the two handrail tubes (i.e., the two first handrail tubes 122) in the corresponding pair of handrail tubes. Fig.34 Thus, when folding this type of bed frame 10, it is also possible to prevent the child's bed covering 1200 or hands from accidentally entering the fourth shearing and stuffing area α1.

[0218] Specifically, see Fig.35 and Fig.36 , the third protective assembly 180 includes a third protective baffle 181 and a third protective connector (not shown in the drawings) that are interconnected. The third protective baffle 181 is used to shield the fourth shearing and stuffing area α1. In this embodiment, the third protective baffle 181 is roughly a rectangular sheet structure, and the third protective connector is arranged at one side edge of the third protective baffle 181. In this embodiment, the third protective baffle 181 and the third protective connector are integrally formed. In other embodiments, the third protective baffle 181 and the third protective connector can also be connected by riveting, welding, etc. A third arc-shaped concave surface (not shown in the drawings) that can fit the outer wall of the handrail tube is formed on the side of the third protective connector facing away from the third protective baffle 181. In this embodiment, two third connecting protrusions (not shown in the drawings) are arranged at intervals on one side of the third arc-shaped concave surface, and each third connecting protrusion is provided with a third connecting hole (not shown in the drawings). In other embodiments, the number of the third connecting protrusions and the third connecting holes can also be more than two or less than two. The corresponding handrail tube is provided with two third fixing holes (not shown in the drawings) respectively corresponding to the two third connection holes, and two fasteners (such as rivets, screws or rivets, etc.) respectively pass through the corresponding third connection holes and the third fixing holes to connect the third protection component 180 and the handrail tube. In this way, the stability of the third protection component 180 after installation can be improved. Of course, in other alternative embodiments, the third protection component 180 can also be connected to the handrail tube by a snap-on method, or the third protection component 180 can also be integrally formed on the handrail tube.

[0219] See also Fig.37 and Fig.38 The fifth embodiment of the present application also provides a bed frame 10, which is a variation of the bed frame 10 shown in the second embodiment, and includes: a plurality of columns 110 and a plurality of armrest tube mechanisms 120. The plurality of columns 110 are arranged at intervals along the circumferential direction, and an armrest tube mechanism 120 is movably connected between each two adjacent columns 110. The armrest tube mechanism 120 includes two pairs of armrest tubes, and the two pairs of armrest tubes are pivotally connected to each other. Specifically, each pair of armrest tubes includes two armrest tubes, and the two armrest tubes are crossed and pivotally connected to each other. Each armrest tube mechanism 120 can be switched between an extended position and a folded position so that the bed frame 10 can be switched between an extended state and a folded state.

[0220] It should be noted that the "pair of handrail tubes" in the fifth embodiment may refer to the second handrail tube 125 and the third handrail tube 126, but it should be emphasized that the second handrail tube 125 and the third handrail tube 126 are straight tubes, which is equivalent to the third tube segment 1252 and the fourth tube segment 1253 being on the same straight line, and the fifth tube segment 1262 and the sixth tube segment 1263 being on the same straight line. In addition, compared with the bed frame 10 in the second embodiment, the bed frame 10 in the fifth embodiment omits the rotating connection mechanism 123, which is equivalent to the second handrail tube 125 and the third handrail tube 126 being directly pivoted instead of being pivoted through the rotating connection mechanism 123.

[0221] For further information, see Fig.39 and Fig.40 , the bed frame 10 in the fifth embodiment further includes a plurality of third protection components 180. Specifically, each pair of handrail tubes is provided with a third protection component 180, and the third protection component 180 is installed on at least one handrail tube and is located at the pivot point of the two handrail tubes, that is, the third protection component 180 can be installed on the second handrail tube 125 and / or the third handrail tube 126. Therefore, when each handrail tube mechanism 120 switches between the unfolded position and the folded position, each third protection component 180 can be used to shield the fourth shearing and filling area α1 formed between the second handrail tube 125 and the third handrail tube 126 (see Fig.34 Thus, when folding this type of bed frame 10, it is also possible to prevent the child's bed covering 1200 or hands from accidentally entering the fourth shearing and stuffing area α1.

[0222] The present application also provides a bed frame 10 (not shown in the figure), which includes a plurality of columns 110 and a plurality of handrail tube mechanisms 120. Among them, the plurality of columns 110 are arranged at intervals along the circumferential direction, and a handrail tube mechanism 120 is movably connected between each two adjacent columns 110. Specifically, for the entire bed frame 10, the handrail tube mechanism 120 includes the handrail tube mechanism 120 in the fourth embodiment mentioned above, and also includes the handrail tube mechanism 120 in the fifth embodiment mentioned above. In other words, the bed frame 10 can also be regarded as similar to the bed frame 10 shown in the third embodiment mentioned above, and the only difference is that each first handrail tube 122 in the first handrail tube group 121 is a straight tube, and the second handrail tube 125 and the third handrail tube 126 in the second handrail tube group 124 are both straight tubes; and the rotating connection mechanism 123 is omitted. The two first armrest tubes 122 in the first armrest tube group 121 are directly pivoted; the second armrest tube 125 and the third armrest tube 126 in the second armrest tube group 124 are directly pivoted. Furthermore, since each armrest tube mechanism 120 of the bed frame 10 is also provided with a third protective assembly 180, the bed frame 10 can still prevent the child's bed covering 1200 from being pinched or the hand from being pinched during the folding process through the third protective assembly 180. In summary, according to the different types of the bed frame 10, different types of protective assemblies (such as the first protective assembly 160, the second protective assembly 170 or the third protective assembly 180, etc.) can be selectively provided on the armrest tubes of the bed frame 10. When each handrail tube mechanism 120 switches between the unfolded position and the folded position, each protective component is used to shield the shearing and clamping area (such as the first shearing and clamping area 127, the second shearing and clamping area 128, the third shearing and clamping area 129, the fourth shearing and clamping area α1, etc.) formed between two handrail tubes in the corresponding pair of handrail tubes. In this way, it can prevent the child's bed covering or hands from being clamped.

[0223] The bed frame 10 and the child bed 1000 proposed in the present application have at least the following technical effects:

[0224] In the bed frame 10 and the children's bed 1000 of the present application, the armrest tube mechanism 120 is movably connected between the first column 111 and the second column 112, so that the armrest tube mechanism 120 can have an extended position and a folded position, and when the armrest tube mechanism 120 is in the folded position, the entire bed frame 10 can be in a folded state, so that the volume of the bed frame 10 becomes smaller for easy storage and transportation. When the armrest tube mechanism 120 is in the extended position, it is at least partially parallel to the horizontal plane. Therefore, when the armrest tube mechanism 120 is in the extended position, the children's bed covering (such as a cloth cover) installed on the armrest tube mechanism 120 tends to be flat, so that it fits better with the armrest tube mechanism 120, thereby making the appearance of the bed frame 10 covered with the children's bed covering neater. In other words, when the bed frame and the children's bed 1000 including the bed frame according to the present application are in the unfolded state, the upper surface of the armrest tube component is flat, so that the children's bed covering laid on the bed frame is more comfortable and flat.

[0225] On the other hand, the bed frame 10 and the child bed 1000 proposed in the present application have at least the following technical effects:

[0226] In the bed frame 10 and the children's bed 1000 of the present application, no matter how the bed frame 10 is constructed (for example, the upper end of the armrest tube mechanism 120 is flat, or the first armrest tube 122, the second armrest tube 125 and the third armrest tube 126 can all be straight tubes, etc.), a protective component can be set to block the shear clamping area (for example, a first protective component 160 is set to block the first shear clamping area 127, a second protective component 170 is set to block the second shear clamping area 128 and the third shear clamping area 129, or a protective component 180 is set to block the fourth shear clamping area α1), so that when the user folds the bed frame 10, not only can the children's bed covering 1200 be prevented from entering the shear clamping area, thereby avoiding affecting the folding smoothness of the bed frame 10, but also the user's hand can be prevented from accidentally entering the shear clamping area, thereby preventing possible pinching.

[0227] Return to see Figures 1 to 4, the child bed cover 1200 of the child bed 1000 may include a bottom support piece 1210 that is substantially rectangular and four side support pieces 1220 that are respectively connected to the four sides of the bottom support piece 1210. The shape of the bottom support piece 1210 is adapted to the horizontal cross-sectional shape of the bed frame 10 in the unfolded state. For example, in this embodiment, the horizontal cross-sectional shape of the bed frame 10 in the unfolded state and the bottom support piece 1210 are both rectangular. More specifically, each side support piece 1220 is connected between the corresponding first column 111 and the second column 112, that is, a side support piece 1220 is connected between each first column 111 and each second column 112. The bottom support piece 1210 is connected to two first columns 111 and two second columns 112. The bottom support piece 1210 and the four side support pieces 1220 enclose a receiving cavity.

[0228] In some embodiments, the crib cover 1200 may further include a protective member 1230. The protective member 1230 is connected to one end of each side support sheet 1220 away from the bottom support sheet 1210, and the protective member 1230 is sleeved on each armrest tube mechanism 120. By connecting the bottom support sheet 1210 and the side support sheet 1220 to the bed frame 10, a storage space for the crib 1000 can be defined, and children can play in the storage space. In addition, the protective member 1230 is sleeved on the armrest tube mechanism 120, which can prevent the armrest tube mechanism 120 from being exposed and causing problems such as bumps and pinching, and at the same time improve the aesthetics of the crib 1000. The protective member 1230 can be made of a flexible material. For example, the protective member 1230 can be a cloth cover.

[0229] In some embodiments, the side support sheet 1220 is, for example, a sheet of cloth, or a sheet of mesh, etc., which is not specifically limited here. Further, when the side support sheet 1220 is a sheet of mesh, the side support sheet 1220 can be regarded as transparent, and the user can observe the situation of the child in the accommodating space at any time from the outside of the bed frame 10.

[0230] Furthermore, in some embodiments, an operating member 1300 (eg, Figure 1 , Figure 2 and Fig.41 ). For example, the operating member 1300 may be a structure such as a webbing, a rope or a ring (such as a hard pull ring, a handle or a hook). In this embodiment, the operating member 1300 may be a webbing pull ring. The operating member 1300 may be operated to switch the bed frame 10 from the unfolded state to the folded state.

[0231] When the user needs to switch the child bed 1000 from the unfolded state to the folded state, the user presses the operating end 1511 to put the locking member 151 in the unlocked position; then, the user pulls the operating member 1300 upward or pushes or pulls the sliding member 140 along the F1 direction, so that the first columns 111 and the second columns 112 included in the bed frame 10 can be brought closer to each other with the cooperation of the armrest tube mechanism 120, the top angle 130 and the sliding member 140, so that the child bed 1000 can be folded.

[0232] See also Figures 1 to 4 as well as Fig.41 and Fig.43 In some embodiments, the child bed 1000 further includes a hammock 200. The hammock 200 is detachably connected to the bed frame 10 and installed in the bed frame 10. Of course, in some alternative embodiments, the hammock 200 can also be fixedly connected to the bed frame 10. In one embodiment of the present application, the hammock 200 can be accommodated in an accommodating cavity formed by the bottom support sheet 1210 and the four side support sheets 1220.

[0233] See also Figure 1 In one embodiment, the hammock 200 is provided with an operating port 201, and the operating port 201 is arranged opposite to the operating member 1300. When the user needs to switch the child bed 1000 from the unfolded state to the folded state, the user can pass the operating port 201 to pull the operating member 1300 upward, and the upward movement of the operating member 1300 drives the bottom support sheet 1210 to fold upward, and the folding of the bottom support sheet 1210 drives the four pillars to fold, so that the child bed 1000 is switched to the folded state. When the child bed 1000 is in the unfolded state, a mattress can be laid in the hammock 200 to cover the operating port 201, so as to facilitate carrying infants and young children. The hammock 200 and the child bed have a small volume after being folded, which is convenient for storage and transportation.

[0234] Specifically, Fig.41 and Fig.43As shown, the hammock 200 includes a hammock covering 210 and a support assembly 220 supported at the bottom of the hammock covering 210. The hammock covering 210 includes a bottom covering 211 that is approximately rectangular and four side coverings 212 that are respectively connected to the four sides of the bottom covering 211. The bottom covering 211 and the four side coverings 212 enclose a receiving chamber 230 for accommodating a mattress 300 and a baby. In this embodiment, the four side coverings 212 are detachably connected to the four side support sheets 1220 through a zipper 240. In other embodiments, the four side coverings 212 can also be detachably connected to the four side support sheets 1220 by button fastening, Velcro bonding, etc., or directly fixedly connected. A first opening 2111 opposite to the operating member 1300 is provided at a substantially central position of the bottom covering 211. In this embodiment, the hammock covering 210 is made of mesh material, so that the entire hammock 200 is more light and breathable. In other embodiments, the hammock covering 210 can also be made of other light and breathable non-mesh materials.

[0235] Specifically, Figure 43 to Figure 45 As shown, the support assembly 220 includes a pivot seat 221 and a plurality of support tube groups 222 circumferentially pivoted to the pivot seat 221. In the present embodiment, the pivot seat 221 is generally an annular structure, and a second opening 2211 is formed in the middle of the pivot seat 221. The second opening 2211 is opposite to the first opening 2111 and the operating member 1300, that is, the operating port 201 of the present application may include the second opening 2211 and the first opening 2111. The operator can operate the operating member 1300 via the second opening 2211 and the first opening 2111. The pivot seat 221 includes a first surface 2212 (such as Fig.45 ) and the second surface 2213 facing the bottom covering 211 (as shown Fig.46 The second surface 2213 of the pivot seat 221 is surrounded by a plurality of pivot assemblies 2214, each of which includes two pivot members 2214a disposed relatively spaced apart. In this embodiment, there are four pivot assemblies 2214, and the support tube assemblies 222 have four corresponding groups and are respectively pivotally connected to the four pivot assemblies 2214.

[0236] Furthermore, when the hammock 200 is in the unfolded state, the length of each support tube group 222 is less than the length of each column 110. Thus, the length of each support tube group 222 is shorter, and the gravity moment of each support tube group 222 is smaller, so that the support stability of the entire support assembly 222 is better.

[0237] Specifically, each support tube group 222 includes a plurality of tube segments connected to each other, and the plurality of tube segments can be at least partially folded together. It should be understood that the term "a plurality" herein refers to at least two. Figure 43 to Figure 45As shown, each support tube group 222 includes a support inner tube 2221 and a support outer tube 2222 slidably sleeved outside the support inner tube 2221. The support inner tube 2221 has a first end 2221a and a second end 2221b, and the support outer tube 2222 has a third end 2222a and a fourth end 2222b. The first end 2221a of the support inner tube 2221 is pivotally connected to the corresponding pivot assembly 2214, the second end 2221b of the support inner tube 2221 is inserted into the support outer tube 2222 through the third end 2222a of the corresponding support outer tube 2222 and slidably sleeved with the support outer tube 2222, and the fourth end 2222b of the support outer tube 2222 away from the pivot seat 221 is connected to the hammock cover 210. In other embodiments not shown, each support tube group 222 includes a first tube segment, a second tube segment, and a third tube segment connected in sequence from close to the pivot seat 221 to away from the pivot seat 221, wherein the second tube segment can be folded and collapsed with the first tube segment, or the second tube segment can be folded and collapsed with the third tube segment. Of course, the present application is not limited thereto, and the support tube group 222 can also be collapsed by other means besides sliding or folding.

[0238] In this embodiment, Fig.43 and Fig.44 As shown, the fourth ends 2222b of the four support tube groups 222 are respectively connected to the four vertex corners of the bottom covering 211. Specifically, the four vertex corners of the bottom covering 211 are respectively provided with sleeves 2112 extending toward the center position of the bottom covering 211. In this embodiment, the sleeve 2112 is sewn on the bottom covering 211 using the same mesh material as the bottom covering 211. The support outer tube 2222 of each support tube group 222 is inserted into the sleeve 2112, and the support outer tube 2222 is fixedly connected to the sleeve 2112 by fasteners 2113 such as rivets. In this embodiment, the length of the sleeve 2112 is the same as the length of the support outer tube 2222. Such a configuration can, on the one hand, prevent the sleeve 2112 from being too long and affecting the extension and retraction of the support tube group 222, and on the other hand, ensure that the sleeve 2112 has a sufficient length so that the support tube group 222 can avoid irregular swinging of the support outer tube 2222 when the child bed 1000 is folded or unfolded, thereby affecting the folding and unfolding.

[0239] like Figure 45 to Figure 47As shown, the support tube group 222 can be switched between an extended state and a shortened state. In this embodiment, the extended state of the support tube group 222 refers to a state in which the first end 2221a of the support inner tube 2221 and the fourth end 2222b of the support outer tube 2222 are farthest apart, and the shortened state of the support tube group 222 refers to a state in which the first end 2221a of the support inner tube 2221 and the fourth end 2222b of the support outer tube 2222 are closest to each other. When the support tube group 222 is in an extended state, the support inner tube 2221 at least partially extends out of the support outer tube 2222. When the support tube group 222 is in a shortened state, the support inner tube 2221 shrinks in the support outer tube 2222, that is, the support inner tube 2221 is completely hidden in the support outer tube 2222. Of course, in other embodiments, the support inner tube 2221 does not necessarily have to be completely hidden in the support outer tube 2222, that is, a part of the support inner tube 2221 is hidden in the support outer tube 2222. When the support tube set 222 is in a shortened state, a distance between the first end 2221a of the support inner tube 2221 and the fourth end 2222b of the support outer tube 2222 is smaller than a distance between the first end 2221a and the fourth end 2222b of the support outer tube 2222 when the support tube set 222 is in an extended state.

[0240] In this embodiment, both the inner tube and the outer tube are hollow tubular structures, and the length of the outer support tube 2222 is greater than or equal to the length of the inner support tube 2221, so that when the support tube group 222 is in a shortened state, the inner support tube 2221 is completely retracted into the outer support tube 2222. In this embodiment, the length of the outer support tube 2222 is slightly greater than the length of the inner support tube 2221 to ensure that the inner support tube 2221 is retracted into the outer support tube 2222 to the maximum extent. In other embodiments, the lengths of the outer support tube 2222 and the inner support tube 2221 can also be adjusted according to the size and folding conditions of the children's bed. Fig.48 and Fig.49 As shown, when the child bed is in the folded state, the plurality of support tube groups 222 pivot relative to the pivot seat 221 to positions substantially located below the pivot seat 221, and the support tube groups 222 switch to the retracted state, so that the child bed can have a smaller volume and is convenient for storage and transportation. The hammock 200 is installed in the bed frame 10, and the hammock 200 can switch between the unfolded state and the folded state. One or more armrest tube mechanisms 120 of the bed frame 10 can constitute the top frame 1110 of the bed frame 10. When the hammock 200 is in the folded state, the folded height of the support assembly 220 is lower than the height of the highest point of the top frame 1110. That is, the length of the support outer tube 2222 is less than or equal to the vertical distance from the bottom covering 211 to the highest point of the top frame 1110 when the hammock 200 is in the unfolded state, so that the overall height of the child bed after folding can be reduced.

[0241] The structure of the support assembly 220 is further described below by taking it as an example:

[0242] like Fig.50 and Fig.51 As shown, the support assembly 220 further includes an anti-contact assembly 223, which is disposed between the support inner tube 2221 and the support outer tube 2222 to prevent the two from directly contacting each other. Specifically, the anti-contact assembly 223 includes a first anti-contact member 2231 disposed on the support inner tube 2221 and a second anti-contact member 2232 disposed on the support outer tube 2222, and both the first anti-contact member 2231 and the second anti-contact member 2232 are at least partially located between the support inner tube 2221 and the support outer tube 2222.

[0243] The anti-contact assembly 223 is set so that only the first anti-contact member 2231 part contacts the support outer tube 2222, and only the second anti-contact member 2232 part contacts the support inner tube 2221. The support inner tube 2221 and the support outer tube 2222 are not in direct contact, the contact area is small, and the sliding is smooth. The first anti-contact member 2231 and the second anti-contact member 2232 can both be made of plastic material to reduce the friction between the support inner tube 2221 or the support outer tube 2222, so that the relative sliding between the support inner tube 2221 and the support outer tube 2222 is smoother.

[0244] like Fig.54 and Fig.55 As shown, the first anti-contact member 2231 includes a first plug-in portion 2231a and a first abutment portion 2231b that are connected to each other. The first plug-in portion 2231a is roughly a cylindrical structure, and a first engaging finger 2231c is provided on the side wall of the first plug-in portion 2231a. The first abutment portion 2231b is roughly a truncated cone structure with a radial dimension larger than the first plug-in portion 2231a. The first abutment portion 2231b is integrally formed with the first plug-in portion 2231a, and the first abutment portion 2231b closes one end of the first plug-in portion 2231a. The first abutment portion 2231b is fixed to one end of the first plug-in portion 2231a and closes one end of the first plug-in portion 2231a. The support inner tube 2221 is provided with a first engaging hole 2221c. When the first contact prevention member 2231 is installed on the support inner tube 2221, the first insertion portion 2231a is inserted into the support inner tube 2221 through the second end 2221b of the support inner tube 2221 and the first engaging finger 2231c is engaged with the first engaging hole 2221c, thereby achieving the fixation of the first contact prevention member 2231 and the support inner tube 2221. The first abutting portion 2231b is located outside the support inner tube 2221 and closes the second end 2221b of the support inner tube 2221. The radial dimension of the first abutting portion 2231b is greater than the outer diameter of the support inner tube 2221.

[0245] like Fig.55As shown, the second anti-contact member 2232 includes a second plug-in portion 2232a and a second abutment portion 2232b that are interconnected. The second plug-in portion 2232a is generally a cylindrical structure, and a second engaging finger 2232c is provided on the side wall of the second plug-in portion 2232a. The second abutment portion 2232b is generally a boss structure integrally formed at one end of the first plug-in portion 2231a. Alternatively, the second abutment portion 2232b is generally a boss structure fixed to one end of the first plug-in portion 2231a. The support outer tube 2222 is provided with a second engaging hole 2222c (see Fig.48 and Fig.49 When the second contact prevention member 2232 is installed on the supporting outer tube 2222, the second insertion portion 2232a is inserted into the supporting outer tube 2222 through the third end 2222a of the supporting outer tube 2222 and the second engaging finger 2232c is engaged with the second engaging hole 2222c, thereby achieving the fixation of the second contact prevention member 2232 and the supporting outer tube 2222.

[0246] Furthermore, if Fig.50 and Fig.51 As shown, the fourth end 2222 b of the supporting outer tube 2222 is further provided with an end cap 224 , and the end cap 224 is at least partially inserted into the supporting outer tube 2222 to close the supporting outer tube 2222 .

[0247] Furthermore, when the hammock 200 is in the unfolded state, the support tube set 222 is in an extended state, and when the hammock 200 is in the folded state, the support tube set 222 is in a shortened state. Fig.51 As shown, the first abutment portion 2231b of the first anti-contact member 2231 and the second insertion portion 2232a of the second anti-contact member 2232 abut to limit the position. In this way, on the one hand, the maximum extension length of the support tube group 222 can be limited, and on the other hand, the support inner tube 2221 can be prevented from falling off from the support outer tube 2222. When the hammock 200 is in the folded state, the first abutment portion 2231b of the first anti-contact member 2231 and the end cover 224 abut to limit the position. Of course, the third end 2222a of the support outer tube 2222, that is, the end of the support outer tube 2222 on which the second anti-contact member 2232 is inserted, can also abut to limit the position with the pivot seat 221.

[0248] The folding process of the child bed in this embodiment is described in detail below:

[0249] When the child bed is folded, after the locking member 151 is released as described above, the four uprights 110 are in the unlocked state. Fig.41As shown, the operating member 1300 can be pulled upward through the first opening 2111 and the second opening 2211 so that the bottom support sheet 1210 is retracted toward the operating member 1300, i.e., toward the center position and pulled upward, and at the same time, the bottom support sheet 1210 drives the four columns 110 to move toward the center position together. In this way, on the one hand, the bottom support sheet 1210 is retracted between the four columns 110 in the retracted state and will not fall down, and on the other hand, the bottom support sheet 1210 being pulled upward will simultaneously generate an upward thrust on the pivot seat 221, so that the support assembly 220 can be well retracted, that is, the support tube group 222 can pivot downward relative to the pivot seat 221, and at the same time, it shrinks to the bottom under the push of the bottom support sheet 1210 and the bottom covering 211. Fig.49 The state shown. Fig.56 The intermediate state shown gradually closes to Fig.57 When the child bed is folded, Fig.58 As shown, the folded child bed can be wrapped with a mattress 300 and fixed by the webbing 310 on the mattress 300. When the hammock 200 is in the folded state, the folded height of the support assembly 220 is lower than the height of the highest point of the top frame 1110. Therefore, the folded hammock 200 is wrapped in the child bed, and the highest point of the hammock 200 is lower than the top frame 1110, so the folded hammock 200 does not affect the folded size of the child bed, so as to ensure that the folded volume of the child bed is smaller.

[0250] In an embodiment not shown, the operating member 1300 may not be provided. When the child bed is folded, the four uprights 110 may be directly unlocked and then folded together by applying external force. At this time, the bottom support sheet 1210 may fall downward under the action of gravity, and the bottom support sheet 1210 needs to be manually pulled up and folded. During the folding process, the support pipe assembly 222 will not automatically pivot downward and shrink relative to the pivot seat 221. At this time, the support assembly 220 will hinder the folding of the child bed as a whole. Therefore, the pivot seat 221 needs to be manually lifted to make the support pipe assembly 222 rotate and shrink relative to the pivot seat 221 before the child bed can be folded to the folded state.

[0251] In this embodiment, during the folding process of the child bed, after the support tube group 222 pivots downward relative to the pivot seat 221, the inner support tube 2221 of the support tube group 222 can automatically slide into the outer support tube 2222, that is, the support tube group 222 can automatically shrink, so that the folded height of the support assembly 220 is lower than the height of the highest point of the top frame 1110. In other embodiments, during the folding process of the child bed, after the support tube group 222 pivots downward relative to the pivot seat 221, the inner support tube 2221 of the support tube group 222 does not automatically slide into the outer support tube 2222. At this time, an external force needs to be applied to make the inner support tube 2221 slide into the outer support tube 2222, so that the support tube group 222 shrinks, so that the folded height of the support assembly 220 is lower than the height of the highest point of the top frame 1110.

[0252] The above-mentioned children's bed and hammock 200 have at least the following technical effects:

[0253] The above-mentioned child bed comprises a bed frame and a hammock, wherein the bed frame comprises a top frame, and the hammock comprises a hammock cover and a support assembly. When the hammock is installed in the bed frame, the child bed can be switched between an unfolded state and a folded state. When the child bed is in the folded state, the folded height of the support assembly is lower than the height of the highest point of the top frame, so that the hammock 200 has a smaller volume after being folded, which is convenient for storage and transportation.

[0254] The technical features of the above embodiments may be combined arbitrarily. To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0255] The above-described embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be construed as limiting the scope of the patent application. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application. Therefore, the protection scope of the patent application shall be subject to the attached claims.
