[0042] 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.

[0043] An embodiment of the present invention provides a baby crib, which is mainly used to provide a place for children or infants to rest or play. Specifically, the baby crib may include a baby crib frame 1000 (see the first embodiment or the second embodiment of the present invention) provided in the present invention. Figure 1 ) and an enclosure (not shown in the figure) arranged on the crib frame 1000. The enclosure defines a first accommodation space of the crib, and children or infants can play in the first accommodation space. The enclosure can be fixedly mounted on the crib frame 1000, or the enclosure can be detachably mounted on the crib frame 1000. Of course, in other alternative embodiments, the crib can also include a hammock (not shown in the figure), which is mounted on the crib frame 1000 and forms a second accommodation space in the hammock, and children or infants can rest in the second accommodation space. The hammock can be fixedly mounted on the crib frame 1000, or the hammock can be detachably mounted on the crib frame 1000. The crib frame 1000 will be explained together with the description of the crib below.

[0044] Figure 1 The three-dimensional diagram of the baby bed frame 1000 in the first embodiment of the present invention is schematically shown. The baby bed frame 1000 is a foldable structure, that is, the baby bed frame 1000 has an unfolded state for use (see FIG. Figure 1) and the folded state for storage (see Figure 3 ), so that the baby bed can also be folded. Specifically, the baby bed frame 1000 may include an armrest assembly 110 and a side rod assembly 120. The armrest assembly 110 includes two armrest tubes 111, and the first ends of the two armrest tubes 111 are pivotally connected to each other so that the armrest assembly 110 can be folded. The side rod assembly 120 includes two columns 121 pivotally connected to each other, and the top ends of the two columns 121 are pivotally and slidably connected to the two armrest tubes 111 respectively. When the baby bed frame 1000 is in the unfolded state, the top ends of the two columns 121 are away from each other and the two armrest tubes 111 are relatively unfolded. In this embodiment, the two armrest tubes 111 are on the same straight line when they are relatively unfolded (see Figure 1 and Figure 2 Of course, in other embodiments, the two armrest tubes 111 may form a certain angle when they are relatively unfolded. When the crib frame 1000 is in the folded state, the top ends of the two uprights 121 are close to each other and the two armrest tubes 111 are relatively folded (see FIG. Figure 3 and Figure 4 ). In this way, the user can pivot the two columns 121 so that the top ends of the two columns 121 are separated from each other to support the two handrail tubes 111 and place the two handrail tubes 111 in the same straight line, thereby placing the baby bed frame 1000 in an unfolded state for use. Alternatively, the user can pivot the two columns 121 so that the top ends of the two columns 121 are relatively close to each other to drive the two handrail tubes 111 to fold relatively, thereby placing the baby bed frame 1000 in a folded state for storage or transportation.

[0045] In the above-mentioned baby crib frame 1000, since the two columns 121 in the side rod assembly 120 are not only respectively connected to the armrest assembly 110, but also cross-connected, compared with the traditional side rod assembly 120, the side rod assembly 120 in the present application has more force support points, and the side rod assembly 120 forms two stable triangular support structures, which enhances the structural strength of the baby crib frame 1000 and makes the baby crib more stable.

[0046] See also Figure 1 and Figure 3In one embodiment, the crib frame 1000 includes a plurality of armrest assemblies 110 and a plurality of side rod assemblies 120, and the number of the armrest assemblies 110 is the same as the number of the side rod assemblies 120, and the two correspond to each other one by one. Specifically, the plurality of armrest assemblies 110 are connected end to end in sequence, which is equivalent to the second ends of the two adjacent armrest tubes 111 of each two adjacent armrest assemblies 110 being pivotally connected to each other. In this way, the armrest assemblies 110 can be enclosed to form an annular frame, which is convenient for supporting the enclosure and / or hammock when the crib frame 1000 is in the unfolded state. More specifically, when the crib frame 1000 is in the unfolded state, the ends of the two uprights 121 of each side rod assembly 120 are away from each other, and the armrest tubes 111 in each armrest assembly 110 are relatively extended and in the same plane. When the crib frame 1000 is in the folded state, the ends of the two upright posts 121 of each side rod assembly 120 are folded together, and the two armrest tubes 111 in each armrest assembly 110 are relatively pivoted and folded. At the same time, the two connected armrest tubes 111 in two adjacent armrest assemblies 110 are pivoted and folded together.

[0047] See 1. Figure 3 and Figure 5 In one embodiment, the crib frame 1000 further includes a corner piece 170, and each armrest assembly 110 is connected by the corner piece 170. Specifically, the second ends of two adjacent armrest tubes 111 of each adjacent armrest assembly 110 are pivotally connected by a corner piece 170. In this way, when the crib frame 1000 is folded, the second end of each armrest tube 111 will pivot around the corresponding corner piece 170, so that the two adjacent armrest tubes 111 in the two adjacent armrest assemblies 110 can be folded relative to each other, thereby reducing the volume of the armrest assembly 110. More specifically, the second end of each armrest tube 111 is sleeved with an armrest grommet 113. The second end of each armrest tube 111 is pivotally connected to the corner piece 170 through the armrest grommet 113. Specifically, the two sides of the corner piece 170 opposite to the two armrest sleeves 113 are respectively provided with a first pivoting inclined surface 171, and the ends of the two armrest sleeves 113 close to the corner piece 170 are respectively provided with a second pivoting inclined surface (not shown in the drawings), and the two second pivoting inclined surfaces of the two armrest sleeves 113 are respectively fitted with the two first pivoting inclined surfaces 171 of the corresponding corner piece 170, and are respectively pivoted by fasteners such as screws. In this way, the second ends of the two armrest tubes 111 can be pivoted to the corner piece 170 at a certain angle through the two armrest sleeves 113. Of course, in other alternative embodiments, the second end of the armrest tube 111 may not be provided with the armrest sleeve 113, and this application does not make any specific restrictions on this.

[0048] See also Figure 1 and Figure 3In one embodiment, the crib frame 1000 further includes a plurality of pivot bases 160, the number of the pivot bases 160 being the same as the number of the side bar assemblies 120, and the two corresponding to each other. Specifically, the bottom ends of two adjacent uprights 121 of two adjacent side bar assemblies 120 are pivotally connected through a corresponding pivot base 160.

[0049] In this embodiment, if Figure 1 As shown, the baby bed frame 1000 specifically includes four armrest assemblies 110, four side rod assemblies 120 and four pivot bases 160. The four pivot bases 160 are arranged in a matrix, and more specifically, the four pivot bases 160 are roughly located directly below the four corner pieces 170. In this way, when the baby bed frame 1000 is in an unfolded state, the four armrest assemblies 110 are enclosed to form a rectangular shape, and a first accommodating space with a cubic structure is formed between the four armrest assemblies 110, the four side rod assemblies 120 and the four pivot bases 160. In this way, the structure of the baby bed frame 1000 is generally symmetrical in both left and right and front and back.

[0050] It should be noted that, unless otherwise clearly specified and limited, the directions such as "front", "back", "left", and "right" of the crib frame 1000 in various embodiments of the present invention can be represented by arrows B, P, L, and R in the figures. These direction terms are only used to make the description of the embodiments of the present invention clearer and are not used to improperly limit the scope of protection of the present invention.

[0051] Furthermore, in one embodiment, the lengths of the armrest tubes 111 in the four armrest assemblies 110 may be the same, or may be different. Specifically, when the lengths of the armrest tubes 111 in the four armrest assemblies 110 are the same, when the crib frame 1000 is unfolded, the four armrest assemblies 110 are enclosed to form a square shape (see FIG. Figure 6 ). When the lengths of the armrest tubes 111 in the two armrest assemblies 110 arranged opposite to each other in the front-to-back direction (first direction F1) are the same, and the lengths of the armrest tubes 111 in the two armrest assemblies 110 arranged opposite to each other in the left-right direction (second direction F2) are the same, and the lengths of the armrest tubes 111 in the two adjacent armrest assemblies 110 are different, at this time, when the baby bed frame 1000 is unfolded, the four armrest assemblies 110 are enclosed to form a rectangular shape (see Figure 1 ).

[0052] In order to clearly illustrate the specific structure and working principle of the baby crib frame 1000 of the present invention, one of the armrest assemblies 110 and a corresponding side rod assembly 120 will be taken as an example for further explanation.

[0053] In one embodiment, the first ends of the two armrest tubes 111 in the armrest assembly 110 may be directly pivotally connected. In other embodiments, the first ends of the two armrest tubes 111 in the armrest assembly 110 may be indirectly pivotally connected. Figure 1 and Figure 2 As shown, the armrest assembly 110 may further include an armrest pivot seat 112, and the first ends of the two armrest tubes 111 in the armrest assembly 110 are respectively pivoted through the armrest pivot seat 112. When the crib frame 1000 is in the unfolded state, the two armrest tubes 111 in each armrest assembly 110 and the corresponding armrest pivot seat 112 are located on the same straight line. When the crib frame 1000 is in the folded state, the two armrest tubes 111 in the armrest assembly 110 are respectively pivoted relative to the armrest pivot seat 112 to fold the armrest assembly 110. Specifically, when each armrest assembly 110 is folded, each armrest tube 111 is parallel to each other.

[0054] See also Figure 1 and Figure 2 In one embodiment, the top end of the column 121 is pivotally and slidably connected to the corresponding handrail tube 111, and the bottom end of the column 121 is connected to the corresponding pivot base 160, so that the column 121 can support the handrail assembly 110. In one embodiment, the column 121 is a straight rod structure (not shown in the figure). Between two mutually pivoted columns 121, the pivot point C1 of the two is located between the top and the bottom of the column 121. Specifically, the pivot point C1 is closer to the top, so that the distance between the bottom ends of the two columns 121 can be increased, so that the side rod assembly 120 is more stable, so as to support the handrail assembly 110.

[0055] In this embodiment, the pillar 121 is bent, for example Figure 1 and Figure 2 As shown, each column 121 includes a first segment 1211, a connecting segment 1213 and a second segment 1212. The first segment 1211 and the second segment 1212 do not extend along the same straight line, and the connecting segment 1213 is connected between the first segment 1211 and the second segment 1212. In this embodiment, the first segment 1211 and the second segment 1212 are substantially parallel. Of course, in other embodiments, the extension direction of the first segment 1211 and the extension direction of the second segment 1212 may also form a certain angle, and this application does not make any specific limitation on this.

[0056] Specifically, the first segment 1211 and the second segment 1212 are both fixed relative to the connecting segment 1213, for example, the three can be formed in an integral manner. Of course, in other alternative embodiments, the first segment 1211 and the second segment 1212 can be detachably connected to the connecting segment 1213, for example, the three can be detachably connected by threaded connection or snap connection. More specifically, the two columns 121 are pivotally connected through the corresponding connecting segment 1213, which is equivalent to the pivot point C1 being located in the connecting segment 1213. The end of the first segment 1211 away from the second segment 1212 is the top of the column 121, which is equivalent to the end of the first segment 1211 away from the second segment 1212 being used for pivoting and sliding connection with the handrail tube 111. The end of the second segment 1212 away from the first segment 1211 is the bottom of the column 121, which is equivalent to the end of the second segment 1212 away from the first segment 1211 being used for pivoting with the pivot base 160.

[0057] Furthermore, if Figure 1 and Figure 2 As shown, in this embodiment, the length of the second segment 1212 is greater than the length of the first segment 1211, so that the pivot point C1 between the two columns 121 can be closer to the top of the column 121, thereby increasing the distance between the bottom ends of the two columns 121, making the side rod assembly 120 more stable. Of course, in other alternative embodiments, the length of the second segment 1212 can be equal to or less than the length of the first segment 1211, so that the pivot point C1 between the two columns 121 can be located in the middle of the column 121 or closer to the bottom end of the column 121.

[0058] See also Figure 2 In one embodiment, the connecting section 1213 is tilted relative to the first section 1211 and the second section 1212. More specifically, in this embodiment, when the baby bed frame 1000 is in the unfolded state, the connecting section 1213 is parallel to the handrail tube 111. This can improve the supporting stability of the side rod assembly 120, make the handrail assembly 110 more stable, and increase the structural strength of the baby bed frame 1000. It should be noted that the "parallel" in this embodiment means approximately parallel, not absolutely completely parallel.

[0059] See also Figure 1 and Figure 2In one embodiment, the baby bed frame 1000 further includes a sliding member 140, and the sliding member 140 is slidably provided on both armrest tubes 111. Each sliding member 140 is provided with a first pivoting portion 141, and the first pivoting portion 141 is used to pivot with the corresponding column 121. In this way, the top end of the column 121 can slide relative to the armrest tube 111 and pivot at the same time through the sliding member 140, so that the baby bed frame 1000 can switch between the unfolded state and the folded state. Specifically, when the two columns 121 in the side rod assembly 120 rotate around the pivot point C1 so that the two columns 121 are close to each other, the top ends of the two columns 121 rotate relative to the corresponding first pivoting portion 141 respectively, and at the same time drive the corresponding sliding member 140 to slide on the armrest tube 111 so that the two sliding members 140 are close to each other, which is equivalent to moving the sliding member 140 in the direction close to the armrest pivot seat 112. As the two sliding members 140 approach the armrest pivot seat 112, the corresponding two armrest tubes 111 gradually rotate around the armrest pivot seat 112 to bend the armrest assembly 110. In other embodiments, the crib frame 1000 may not include the sliding member 140, and the top ends of the two columns 121 are directly pivotally and slidably connected to the armrest tube 111. For example, the top end of the column 121 has two forked portions, and the two forked portions are connected by a sliding pin. Long sliding grooves are provided on two opposite sides of the armrest tube 111, and the sliding pins of the forked portions of the column 121 are engaged in the long sliding grooves and can slide and rotate in the long sliding grooves. Figure 2 Taking the armrest assembly 110 shown in the figure as an example, the two armrest tubes 111 distributed along the front-to-back direction, which is equivalent to the first direction F1, can be respectively turned and rotated along D1 and D2 around the armrest pivot seat 112; in other words, the two armrest tubes 111 arranged on both sides of the armrest pivot seat 112 along the front-to-back direction can be respectively turned and rotated along D1 and D2 for folding.

[0060] See also Figure 2 In one embodiment, the baby bed frame 1000 further includes a first limiter 150. The first limiter 150 is provided on each of the two armrest tubes 111 in each armrest assembly 110. The first limiter 150 is used to limit the sliding stroke of the column 121 on the corresponding armrest tube 111. Specifically, the column 121 is pivotally and slidably connected to the corresponding armrest tube 111 through the sliding member 140. The first limiter 150 is located on the sliding path of the sliding member 140 and is used to constrain the sliding stroke of the sliding member 140. In this way, the sliding distance of the column 121 on the armrest tube 111 can be limited, and then the pivot angle between the two pivotally connected columns 121 can be constrained, while avoiding possible sliding of the sliding member 140 under the action of unexpected external forces. Of course, in other alternative embodiments, the first limiter 150 may not be provided on each armrest tube 111, and this application does not make any specific restrictions on this.

[0061] See also Figure 1and Figure 2 In one embodiment, the crib frame 1000 may further include a folding support assembly 130. Specifically, the folding support assembly 130 includes two support members 131. The two support members 131 may be made of plastic or metal, but the present invention is not limited thereto. More specifically, one end of the two support members 131 is respectively pivotally connected to the armrest pivot seat 112, and the other end of the two support members 131 is respectively pivotally connected to the two columns 121. When the crib frame 1000 is in the unfolded state, the other ends of the two support members 131 move away from each other along with the two columns 121, which is equivalent to making the two support members 131 relatively unfolded and present an inverted V-shaped structure (see FIG. 1 ). Figure 1 and Figure 2 ). The support member 131 and the corresponding column 121 and the armrest tube 111 form a structure that is approximately triangular, so that the stability of the column 121 when supporting the armrest tube 111 can be enhanced. In addition, during the folding process of the baby bed frame 1000, when the two columns 121 in the side rod assembly 120 pivot and approach each other, the upper end of the support member 131 generates an upward thrust on the armrest pivot seat 112, so that the armrest tube 111 can pivot and fold, thereby assisting the folding of the baby bed frame 1000. When the baby bed frame 1000 is in the folded state, the other ends of the two support members 131 move closer to each other with the two columns 121 and are at least partially parallel.

[0062] In one embodiment, if Figure 2 As shown, the support member 131 includes a first support section 1311 and a second support section 1312. The first support section 1311 is connected to the second support section 1312 and is arranged at an angle, and the opening of the angle α1 between the two is arranged upward along the height direction (third direction F3) of the baby bed frame 1000, that is, the angles α1 of the two support members 131 are arranged opposite to each other. More specifically, the angle α1 between the first support section 1311 and the second support section 1312 is an obtuse angle. One end of the first support section 1311 away from the second support section 1312 is pivotally connected to the column 121, and one end of the second support section 1312 away from the first support section 1311 is pivotally connected to the armrest pivot seat 112. When the baby bed frame 1000 is folded, the second support sections 1312 of the two support members 131 are parallel to each other. Of course, in other alternative embodiments, the opening of the angle α1 between the first support segment 1311 and the second support segment 1312 can also be set downward along the third direction F3, that is, the angle α1 of the two support members 131 is set facing each other. Alternatively, the angle α1 between the first support segment 1311 and the second support segment 1312 can be a right angle or an acute angle, and the present invention is not limited to this. In other alternative embodiments, when the baby bed frame 1000 is folded, the second support segments 1312 of the two support members 131 can also be set at an angle.

[0063] See also Figure 1 and Figure 2In one embodiment, the two support members 131 are respectively located on both sides of the armrest pivot seat 112, which is equivalent to the two support members 131 being respectively located on the inner side and the outer side of the armrest pivot seat 112. Of course, in other alternative embodiments, the two support members 131 may be located on the same side of the armrest pivot seat 112, which is equivalent to the two support members 131 being simultaneously located on the inner side or the outer side of the armrest pivot seat 112. It should be noted that the inner side of the armrest pivot seat 112 refers to the side of the armrest pivot seat 112 facing the first accommodation space or the second accommodation space. The outer side of the armrest pivot seat 112 refers to the side of the armrest pivot seat 112 facing away from the first accommodation space or the second accommodation space.

[0064] In one embodiment, if Figure 2 As shown, the two support members 131 pivot coaxially relative to the armrest pivot seat 112. Of course, in other embodiments, the two support members 131 and the pivot axis of the armrest pivot seat 112 may also be staggered.

[0065] See also Figure 1 and Figure 6 In one embodiment, the baby bed frame 1000 further includes a connecting assembly 180. The connecting assembly 180 may include a central pivot 181 and a plurality of bottom rods 182. The number of the bottom rods 182 is the same as the number of the pivot base 160, and the two correspond to each other. Specifically, one end of each bottom rod 182 is pivoted to the central pivot 181 so that the connecting assembly 180 has an extended state and a folded state, and the other end of each bottom rod 182 is pivoted to the corresponding pivot base 160. When the baby bed frame 1000 is in an extended state, the connecting assembly 180 is in an extended state. When the baby bed frame 1000 is in a folded state, the connecting assembly 180 is in a folded state. In this way, the side rod assembly 120, the armrest assembly 110, etc. can be driven to fold by folding the connecting assembly 180, thereby realizing the rapid folding of the baby bed frame 1000.

[0066] Continue to see Figure 1 and Figure 6 In one embodiment, a pulling member 190 is provided on the central pivot member 181. The pulling member 190 can be operated to switch the connecting assembly 180 from the extended state to the retracted state. In this way, the connecting assembly 180 can be quickly retracted by manipulating the pulling member 190.

[0067] The following example uses a baby crib frame 1000 including four armrest assemblies 110, four side bar assemblies 120 and four pivot bases 160, and combines Figure 1 and Figure 3 The unfolding and folding process of the crib frame 1000 is described below.

[0068] See also Figure 1When the crib frame 1000 is in the unfolded state, the four pivot bases 160 are respectively located at the four corners of the virtual quadrilateral. At this time, the two columns 121 in each side bar assembly 120 are unfolded (i.e., the top ends between the two columns 121 and the bottom ends between the two columns 121 are far away from each other), and the top ends of the two columns 121 support the corresponding handrail tubes 111, so that the corresponding handrail assembly 110 is in the unfolded state (i.e., the two handrail tubes 111 are on the same straight line). At the same time, the connecting assembly 180 is in the extended state. At this time, each bottom bar 182 is radially structured with the central pivot 181 as the center, and each bottom bar 182 and the central pivot 181 are in the same plane.

[0069] Continue to see Figure 1 When the user needs to switch the baby bed frame 1000 from the unfolded state to the folded state (i.e. Figure 1 The displayed status switches to Figure 3 (when in the state shown), the user can directly pull the pulling member 190 upwards along the third direction F3. Subsequently, the pulling member 190 drives the central pivot member 181 to move upwards, and each bottom rod 182 pivots relative to the central pivot member 181 and moves toward the central axis X1-X1 of the central pivot member 181. In this process, each bottom rod 182 drives the corresponding pivot base 160 to move closer to each other, which is equivalent to driving each pivot base 160 to move closer to the central axis X1-X1, and the straight-line distance between two adjacent pivot bases 160 gradually decreases. At the same time, the two columns 121 pivoted to each other in each side rod assembly 120 are gradually retracted by sliding toward each other on the handrail tube 111 through two sliding members 140, and the two support members 131 in each folding support assembly 130 pivot as the two columns 121 are retracted. Figure 2 For example, the two support members 131 arranged on both sides of the armrest pivot seat 112 along the front-to-back direction (i.e., the first direction F1) are pivoted along the directions D1 and D2 respectively so that the bottom ends of the two support members 131 are close to each other, and the upper ends of the two support members 131 push the armrest pivot seat 112 upward, so that the two armrest tubes 111 in each armrest assembly 110 are pivoted relative to the corresponding armrest pivot seat 112. Figure 2 For example, the two armrest tubes 111 arranged on the left and right sides of the armrest pivot seat 112 along the front-to-back direction also pivot along the directions D1 and D2 respectively to make the bottom ends of the two support members 131 approach each other. The second ends of the two adjacent armrest tubes 111 in the two adjacent armrest assemblies 110 pivot relative to the corresponding corner member 170 to be folded. It can be seen that when the user needs to fold the baby bed frame 1000, the baby bed frame 1000 can be quickly folded by pulling the pull member 190 upwards.

[0070] Figure 7A three-dimensional view of a baby crib frame 1000 provided according to a second embodiment of the present invention is shown. The baby crib frame 1000 is similar to the first embodiment described above, and includes components such as a side bar assembly 120, an armrest assembly 110, a pivot base 160, and a connecting assembly 180. The baby crib frame 1000 of this embodiment is a variation of the baby crib frame 1000 of the first embodiment described above. In the absence of conflict, the structure of the components in this embodiment and the connection relationship between the components can refer to the description of the first embodiment above, and the following mainly describes the differences between this embodiment and the first embodiment described above.

[0071] Combination Figure 7 and Figure 8 In the second embodiment of the present invention, the connection assembly 180 is modified. Compared with the connection assembly 180 in the first embodiment, the connection assembly 180 in the second embodiment further includes a reinforcing frame 183, which is arranged between two adjacent bottom bars 182. In this way, the structural strength of the connection assembly 180 when in the extended state can be improved, and the stability of the connection assembly 180 itself can be improved, so that the stability of the side bar assembly 120 connected to each pivot base 160 can be higher. Of course, in one embodiment, the connection assembly 180 can include one reinforcing frame 183 or multiple reinforcing frames 183. For example, taking the connection assembly 180 with four bottom bars 182 as an example, the connection assembly 180 can be provided with two reinforcing frames 183, and the two reinforcing frames 183 are arranged between two different bottom bars 182 and are arranged opposite to each other. Of course, in other embodiments, the connection assembly 180 can also include four reinforcing frames 183, and a reinforcing frame 183 is provided between each two adjacent bottom bars 182. For the same bottom bar 182 , the reinforcing frames 183 on both sides thereof are connected at different positions, which is equivalent to that each bottom bar 182 is provided with two connecting points for connecting the reinforcing frames 183 on both sides of the bottom bar 182 .

[0072] In one embodiment, if Figure 7 and Figure 8As shown, the reinforcing frame 183 may include, for example, two reinforcing rods 1831, one end of the two reinforcing rods 1831 is pivoted to each other, and the other end of the two reinforcing rods 1831 is pivoted to two adjacent bottom rods 182 respectively. Such a configuration can maximally avoid interference between the reinforcing frame 183 and the bottom rods 182 when the connecting assembly 180 is folded, thereby affecting the folding of the connecting assembly 180. When the pulling member 190 is pulled upward along the third direction F3, each bottom rod 182 will still pivot relative to the central pivot 181 and move closer to the central axis X1-X1. In this process, each adjacent bottom rod 182 moves closer to each other, and the reinforcing frame 183 bends and folds in the direction close to the central pivot 181 (that is, equivalent to the end of the two reinforcing rods 1831 in the reinforcing frame 183 being pivoted to the direction of the central pivot 181, and the other end of the two reinforcing rods 1831 can pivot relative to the corresponding bottom rod 182 respectively), so that the connecting assembly 180 is folded.

[0073] It should be noted that “one end of the two reinforcing rods 1831 is pivoted to each other” includes two implementations: direct pivoting and indirect pivoting. “The other ends of the two reinforcing rods 1831 are respectively pivoted to the two adjacent bottom rods 182” also includes two implementations: direct pivoting and indirect pivoting. Specifically, in this embodiment, one end of the two reinforcing rods 1831 is connected by an indirect pivoting method, and the other ends of the two reinforcing rods 1831 are respectively connected to the two adjacent bottom rods 182 by an indirect pivoting method. More specifically, as Figure 8 As shown, the reinforcing frame 183 also includes a support seat 1832 and a connecting seat 1833. One end of the two reinforcing rods 1831 is pivoted through the support seat 1832. The other ends of the two reinforcing rods 1831 are respectively pivoted to the corresponding bottom rod 182 through a connecting seat 1833. Of course, in other alternative embodiments, one end of the two reinforcing rods 1831 is directly pivotally connected, and the other ends of the two reinforcing rods 1831 are respectively directly pivotally connected to two adjacent bottom rods 182. It should be noted that in other embodiments in which four reinforcing frames 183 are provided, the reinforcing frames 183 on both sides of the bottom rod 182 are connected to the same bottom rod 182 through different connecting seats 1833.

[0074] In order to improve the smoothness of the pivoting of the reinforcing rod 1831 so that the reinforcing frame 183 can be folded more smoothly, in one embodiment, as shown in FIG. Figure 8As shown, the connection seat 1833 is sleeved outside the corresponding bottom rod 182 and can rotate relative to the bottom rod 182, that is, the connection seat 1833 can rotate around the bottom rod 182. The connection seat 1833 is provided with a second pivot portion 18331, and the reinforcing rod 1831 is pivotally connected to the corresponding second pivot portion 18331, and the pivot axis X2-X2 of the reinforcing rod 1831 around the second pivot portion 18331 is perpendicular to the bottom rod 182. Thus, when the pulling member 190 is pulled upward along the third direction F3, each bottom bar 182 pivots relative to the central pivot member 181 and approaches the central axis X1-X1. At the same time, two adjacent bottom bars 182 approach each other to push the two reinforcing bars 1831 to rotate around the corresponding pivot axis X2-X2, thereby bending the reinforcing frame 183 in the direction away from the central pivot member 181, which is equivalent to pushing the reinforcing bar 1831 to rotate around the corresponding pivot axis X2-X2, so that the end of the reinforcing bar 1832 pivoted to the central pivot member 181 moves toward the direction close to the central pivot member 181. In this process, the connecting seat 1833 rotates around the bottom bar 182, thereby improving the flexibility of the reinforcing frame 183 in folding, thereby improving the smoothness of the reinforcing frame 183 in folding along with each bottom bar 182.

[0075] Furthermore, in one embodiment, the reinforcing frame 183 may further include a limiting structure 1834. The limiting structure 1834 is used to limit the rotation range of the connecting seat 1833 relative to the bottom rod 182. In this way, it is possible to prevent the reinforcing rod 1831 from rotating arbitrarily during the pivoting process, thereby affecting the folding of the reinforcing frame 183.

[0076] Continue to see Figure 8 In one embodiment, the limiting structure 1834 may include a limiting hole 18341 and a second limiting member 18342. One of the limiting hole 18341 and the second limiting member 18342 is disposed on the connecting seat 1833, and the other is mounted on the bottom rod 182. The limiting hole 18341 extends in the circumferential direction around the bottom rod 182 and slidably cooperates with the second limiting member 18342. Specifically, in the present embodiment, the limiting hole 18341 is disposed on the connecting seat 1833 and extends in the circumferential direction around the bottom rod 182. The second limiting member 18342 is mounted on the bottom rod 182 and slidably cooperates with the limiting hole 18341. The extension length of the limiting hole 18341 in the circumferential direction around the bottom rod 182 is the rotation range of the connecting seat 1833 relative to the bottom rod 182.

[0077] The above-mentioned crib and crib frame 1000 have at least the following technical effects:

[0078] In the baby bed frame 1000 of the present invention, the armrest assembly 110 includes two armrest tubes 111 that can be folded relative to each other, and the side rod assembly 120 includes two columns 121 that are cross-pivoted to each other, and the top ends of the two columns 121 are respectively pivoted and slidably connected to the two armrest tubes 111, so that the user can pivot the two columns 121 so that the top ends of the two columns 121 are separated from each other to support the two armrest tubes 111 and place the two armrest tubes 111 in the same straight line, thereby placing the baby bed frame 1000 in an unfolded state for use. Alternatively, the user can pivot the two columns 121 so that the top ends of the two columns 121 are relatively close to each other to drive the two armrest tubes 111 to fold relative to each other, thereby placing the baby bed frame 1000 in a folded state for storage or transportation. In the above-mentioned baby crib frame 1000, since the two columns 121 in the side rod assembly 120 are not only respectively connected to the armrest assembly 110, but also cross-connected, compared with the traditional side rod assembly 120, the side rod assembly 120 in the present application has more force support points, thereby enhancing the structural strength of the baby crib frame 1000 and making the baby crib more stable.

[0079] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described 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.

[0080] 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.
