[0002] A children's bed provides a space for children to sleep or play. Children's beds can be folded for storage, enhancing their convenience. They typically consist of a base structure, support legs, and a railing at the top of the legs. Before switching the bed from its unfolded to its folded state, the base structure needs to be unlocked. In current technology, the complex base structure makes unlocking inconvenient, increasing the difficulty of folding the bed, the user's workload, and hindering the improvement of folding efficiency.

[0003] Therefore, improvements to existing technologies are necessary. Utility Model Content

[0004] This application aims to solve at least one of the technical problems existing in the prior art by providing a base assembly and a children's bed.

[0005] According to one aspect of this application, a base assembly is provided for a children's bed, the children's bed having an unfolded form and a folded form; the base assembly includes a connecting seat, a base rod, a locking member, and a driving member; the connecting seat has a limiting portion; the base rod is spaced apart along the periphery of the connecting seat, and the base rod is hinged to the connecting seat; the locking member is connected to the end of the base rod near the connecting seat by an elastic member, and the end of the locking member near the connecting seat is provided with a snap-fit ​​groove; when the children's bed is in the unfolded form, the limiting portion abuts against the locking member to restrict the rotation of the base rod relative to the connecting seat; the driving member slides vertically against the connecting seat, the driving member being configured to drive the locking member away from the limiting portion along the axial direction of the base rod to release the rotation restriction of the base rod relative to the connecting seat, and to cause the end of the driving member near the locking member to snap into the snap-fit ​​groove.

[0006] In one embodiment, the end of the drive member near the locking member has a first guide surface and a second guide surface that are connected and angled together. The second guide surface is disposed at the bottom of the first guide surface. When the child bed is in the unfolded state, the locking member is disposed between the limiting part and the first guide surface. The included angles between the first guide surface and the second guide surface and the horizontal plane are both acute angles, and the first guide surface and the second guide surface cooperate to form a corner portion, which is engaged with the engaging groove.

[0007] In one embodiment, the corner extends to the side of the limiting portion facing the bottom rod.

[0008] In one embodiment, the locking member has a third guide surface, and when the children's bed is in the unfolded state, the third guide surface abuts against the first guide surface.

[0009] In one embodiment, the connector is provided with a plug hole, the wall of the plug hole is provided with a sliding groove extending in a vertical direction, the sliding groove is adapted to the drive member; the base assembly further includes a lifting member, the lifting member is plugged into the plug hole, the drive member is connected to the lifting member, and the end of the drive member passes through the sliding groove.

[0010] In one embodiment, the sliding groove has a first groove segment and a second groove segment, the first groove segment is disposed at the top of the second groove segment, and the driving member is slidably connected to the first groove segment; the bottom of the lifting member is provided with a limiting pin, and the limiting pin is slidably connected to the second groove segment.

[0011] In one embodiment, the base rod is hinged to the connecting seat via a pivot; the locking member is provided with a guide groove that extends axially along the base rod, the locking member is inserted into the base rod, and the pivot is inserted into the guide groove.

[0012] According to another aspect of this application, a children's bed is provided, including any of the aforementioned base assemblies; the children's bed further includes a railing assembly and support legs, the railing assembly including a connecting rod and a connector, one end of the connecting rod being hinged to the connector; one end of the support leg being hinged to the end of the base rod away from the connecting seat, and the other end being hinged to the end of the connecting rod away from the connector.

[0013] The beneficial effects of this application are as follows: the locking state of the locking component is released by the driving component. The driving component moves upward relative to the connecting seat. During the movement of the driving component, the driving component pushes the locking component to move axially along the bottom rod, releasing the locking component from the limiting part until the end of the driving component near the locking component is engaged in the locking groove at the end of the locking component. At this time, the driving component and the locking groove cooperate with each other, eliminating the need for manual control of the driving component. The locking groove can limit the relative position of the driving component and the locking component, reducing labor intensity and preventing the driving component from slipping off the end of the locking component due to gravity, external influences, or other factors, thus losing the restriction on the position of the locking component. The locking groove ensures that the locking component is always in the unlocked state during the subsequent folding of the children's bed. The structure is simple, which is conducive to the smooth folding of the children's bed and improves the efficiency of folding the children's bed. Attached Figure Description

Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection, an electrical connection, or a connection that allows communication between them; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication between two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0034] The base assembly and children's bed of this application will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0035] In the existing technology, the base structure is relatively complex, the unlocking operation is inconvenient, which increases the difficulty of folding the children's bed, increases the labor intensity of the user, and is not conducive to improving the efficiency of folding the children's bed.

[0036] To address the aforementioned technical problems, this application provides a base assembly for a children's bed, the children's bed having an unfolded form and a folded form. The base assembly includes a connecting seat, a base rod, a locking member, and a driving member. The connecting seat has a limiting portion. The base rod is spaced apart along the periphery of the connecting seat and is hinged to the connecting seat. The locking member is connected to the end of the base rod near the connecting seat via an elastic member, and the end of the locking member near the connecting seat has a locking groove. When the children's bed is in the unfolded form, the limiting portion abuts against the locking member to restrict the rotation of the base rod relative to the connecting seat. The driving member slides vertically against the connecting seat, and is configured to drive the locking member away from the limiting portion along the axial direction of the base rod, thereby releasing the rotation restriction of the base rod relative to the connecting seat and causing the end of the driving member near the locking member to engage with the locking groove. This will be described in detail below.

[0037] See Figure 1-5The base assembly is used in a children's bed, which has an unfolded form and a folded form. The base assembly includes a connecting seat 10, a base rod 20, a locking member 30, and a driving member 50. The connecting seat 10 has a limiting part 11. The base rod 20 is spaced along the periphery of the connecting seat 10 and is hinged to the connecting seat 10. The locking member 30 is connected to the end of the base rod 20 near the connecting seat 10 by an elastic member 40, and the end of the locking member 30 near the connecting seat 10 is provided with a snap-fit ​​groove 31. When the children's bed is in the unfolded form, the limiting part 11 abuts against the locking member 30 to restrict the rotation of the base rod 20 relative to the connecting seat 10. The driving member 50 slides vertically on the connecting seat 10 and is configured to drive the locking member 30 away from the limiting part 11 along the axial direction of the base rod 20 to release the rotation restriction of the base rod 20 relative to the connecting seat 10 and to make the end of the driving member 50 near the locking member 30 snap into the snap-fit ​​groove 31.

[0038] During the use of the children's bed, the children's bed has an unfolded form and a folded form. In this embodiment, when the children's bed is in the unfolded form, the locking member 30 and the limiting part 11 on the connecting seat 10 cooperate with each other. That is, the limiting part 11 can restrict the locking member 30 (i.e., the bottom rod 20) from rotating relative to the connecting seat 10. In other words, the bottom rod 20 and the connecting seat 10 are in a relatively static state through the cooperation of the locking member 30 and the limiting part 11, which helps to improve the stability of the unfolded form of the children's bed. When the children's bed needs to switch from the unfolded form to the folded form, the locking state of the locking member 30 needs to be released (i.e., the limitation of the bottom rod 20 position by the limiting part 11 is released), so that the bottom rod 20 can rotate relative to the connecting seat 10 to realize the folding operation of the children's bed.

[0039] In this embodiment, the locking state of the locking member 30 is released by the driving member 50. The driving member 50 moves upward relative to the connecting seat 10. During the movement of the driving member 50, the driving member 50 pushes the locking member 30 to move axially along the bottom rod 20 (moving away from the connecting seat 10), so that the locking member 30 moves away from the limiting part 11, releasing the locking part 11 from locking the locking member 30, until the end of the driving member 50 near the locking member 30 is engaged in the engaging groove 31 at the end of the locking member 30. At this time, the driving member 50... The drive member 50 and the locking member 30 cooperate with each other. The locking member 31 can restrict the relative position of the drive member 50 and the locking member 30 (that is, ensure that the drive member 50 abuts against the locking member 30, that is, ensure that the locking member 30 is always in the unlocked state). This prevents the drive member 50 from slipping off the end of the locking member 30 due to gravity, external influences or other factors, and thus loses the restriction on the position of the locking member 30 (the position where the locking member 30 is in the unlocked state), causing the locking member 30 to return to the locked state, thereby affecting the subsequent folding and closing operation of the children's bed.

[0040] The snap-fit ​​groove 31 ensures that the locking member 30 remains unlocked (i.e., the locking state is released) during the subsequent folding of the children's bed, facilitating smooth folding. To further illustrate this, a counterexample is provided below: The locking member 30 does not have a snap-fit ​​groove 31 at its end; that is, the end of the locking member 30 near the connecting seat 10 is arranged in a vertical plane (when the children's bed is in its unfolded state). After the driving member 50 moves the locking member 30 away from the limiting part 11, the driving member 50 abuts against this plane. During the subsequent folding of the children's bed (the connecting seat 10 drives the driving member 50 to continue moving upwards),... Since the end of the base rod 20 is hinged to the connecting seat 10, the base rod 20 will rotate relative to the connecting seat 10. That is, during the upward movement of the connecting seat 10, the locking member 30 set at the end of the base rod 20 rotates relative to the connecting seat 10 (i.e., the driving member 50). That is, the end of the locking member 30 near the connecting seat 10 moves upward relative to the driving member 50. During the upward movement of the end of the locking member 30, due to the loss of the restriction of the locking groove 31, the driving member 50 is more likely to slip off from the above-mentioned plane and lose the limiting effect on the locking member 30. Under the action of the elastic member 40, the locking member 30 is easy to return to the locked state, which is not conducive to the folding operation of the children's bed.

[0041] The specific process of switching the children's bed from unfolded to folded mode is as follows: First, the drive component 50 is moved upward. During the upward movement of the drive component 50, the locking component 30 is pushed along the axial direction of the base rod 20 towards the side away from the connecting seat 10 until the end of the drive component 50 near the locking component 30 is engaged in the locking groove 31. The locking groove 31 prevents the drive component 50 from sliding downward, ensuring the restriction of the locking component 30's position. Furthermore, it eliminates the need to lift the drive component 50 by hand, freeing up both hands and facilitating subsequent folding operations. Next, the connecting seat 10 is moved upward. During this upward movement, the base rod 20 rotates relative to the connecting seat 10, and the locking component 30 rotates with the base rod 20 to the side of the limiting part 11. Figure 6 From the perspective of the right side of the limiting part 11, at this time the limiting part 11 will not restrict the rotation of the locking part 30 (i.e. the bottom rod 20). Continue to move the connecting seat 10 upward until the bottom rod 20 is in a vertical state, and complete the folding operation of the children's bed. The structure is simple and the operation is convenient. Just move the driving part 50 upward and then move the connecting seat 10 upward to complete the folding operation of the children's bed.

[0042] It is worth mentioning that the locking member 30 is connected to the end of the base rod 20 near the connecting seat 10 by the elastic member 40. When the children's bed is in the unfolded state, the elastic member 40 of the locking member 30 maintains its engagement with the limiting part 11 under the elastic force. When the locking member 30 is released, the locking member 30 is driven to move by the driving member 50. During the movement of the locking member 30, the elastic member 40 is compressed, which can ensure that the locking member 30 is pressed against the end of the driving member 50, thus ensuring the stability of the unlocked state of the locking member 30.

[0043] It should be noted that, in this application, when the children's bed is processed into its unfolded form, if... Figure 3 As shown, one end of the base rod 20 is restricted from rotating clockwise by the cooperation of the locking member 30 and the limiting part 11. At the same time, the side of the base rod 20's rotating shaft 80 away from the locking member 30 is restricted from rotating counterclockwise by the connecting seat 10. This will not be described in detail here.

[0044] In some embodiments, the end of the drive member 50 near the locking member 30 has a first guide surface 51 and a second guide surface 52 connected and angled together. The second guide surface 52 is disposed at the bottom of the first guide surface 51. When the children's bed is in the unfolded state, the locking member 30 is disposed between the limiting part 11 and the first guide surface 51. The included angles between the first guide surface 51 and the second guide surface 52 and the horizontal plane are both acute angles, and the first guide surface 51 and the second guide surface 52 cooperate to form a corner part 53, which is engaged in the engaging groove 31.

[0045] The angle between the first guide surface 51 and the horizontal plane is an acute angle, and the angle between the second guide surface 52 and the horizontal plane is also an acute angle, meaning that both the first guide surface 51 and the second guide surface 52 are inclined (relative to the horizontal plane). When the children's bed is in the unfolded state, the locking member 30 is located between the first guide surface 51 and the limiting part 11, meaning that the locking member 30 abuts against the first guide surface 51. When the locking member 30 needs to be unlocked, the setting of the first guide surface 51 allows the driving member 50 to drive the locking member 30 more smoothly, reducing the force required to lift the driving member 50, reducing labor intensity, and making the structure simple and easy to use.

[0046] When the locking member 30 is released from its locking state and the child bed continues to be folded, the second guide surface 52 facilitates the smooth separation of the locking member 30 from the drive member 50 and its entry into the right side of the limiting part 11. Figure 6 (View) That is, through the guiding effect of the second guide surface 52, the locking part 30 can smoothly enter the right side of the limiting part 11, which improves the smoothness of the rotation of the bottom rod 20, improves the folding efficiency of the children's bed, and reduces the labor intensity when folding the children's bed.

[0047] In addition, the first guide surface 51 and the second guide surface 52 cooperate to form a corner 53, which can better cooperate with the locking groove 31, making it less likely for the drive member 50 to slip off from the end of the locking member 30 (i.e., the locking groove 31).

[0048] In some embodiments, the corner portion 53 extends to the side of the limiting portion 11 facing the bottom rod 20.

[0049] In this embodiment, Figure 6 From the perspective, the corner 53 extends to the right side of the limiting part 11. When the children's bed is folded, the locking part 30 can be pushed as far to the right as possible, away from the limiting part 11, so as to avoid the limiting part 11 interfering with the locking part 30 during the folding process and affecting the folding efficiency of the children's bed.

[0050] Specifically, when the locking member 30 needs to be released from its locked state, the driving member 50 can push the locking member 30 to a side (right side) further away from the limiting part 11, so that the locking member 30 is completely unlocked; during the upward movement of the connecting seat 10, the locking member 30 can be better guided to the right side of the limiting part 11, which improves the smoothness of the folding of the children's bed and thus improves the folding efficiency of the children's bed.

[0051] In some embodiments, the locking member 30 is provided with a third guide surface 32, which abuts against the first guide surface 51 when the child bed is in the unfolded state.

[0052] The third guide surface 32 abuts against the first guide surface 51, that is, the third guide surface 32 is inclined. By setting the third guide surface 32, the smoothness of the drive member 50 driving the locking member 30 is improved, and the locking member 30 can move better to the side away from the connecting seat 10, reducing labor intensity. At the same time, when the children's bed switches from the folded form to the unfolded form, it is conducive to the smooth unfolding of the children's bed and reduces the difficulty of operation.

[0053] Specifically, with Figure 7 Taking the perspective as an example, when the connecting seat 10 is pressed down, the connecting seat 10 drives the bottom rod 20 to rotate counterclockwise. During the rotation of the bottom rod 20, the third guide surface 32 abuts against the right side of the limiting part 11. The third guide surface 32 can smoothly slide past the right side of the limiting part 11, that is, the locking part 30 can smoothly slide to the bottom of the limiting part 11, thereby locking the locking part 30 and completing the unfolding operation of the children's bed.

[0054] It should be noted that after the children's bed is folded up, the drive unit 50 will automatically fall back to its original position (or be manually driven). When the children's bed switches from the folded state to the unfolded state, the locking unit 30 will spring back to the bottom of the limiting part 11 under the action of the elastic member 40 and press against the first guide surface 51.

[0055] In some embodiments, the connector 10 is provided with a plug hole 12, and the wall of the plug hole 12 is provided with a sliding groove 121 extending in the vertical direction. The sliding groove 121 is adapted to the drive member 50. The base assembly also includes a lifting member 60, which is plugged into the plug hole 12. The drive member 50 is connected to the lifting member 60, and the end of the drive member 50 passes through the sliding groove 121.

[0056] The drive component 50 is connected to the lifting component 60. In actual use, simply moving the lifting component 60 upwards will move the drive component 50 to unlock the locking component 30. When multiple bottom rods 20 need to be unlocked, the lifting component 60 can simultaneously lift multiple drive components 50 (the drive components 50 shown in the figure are symmetrically arranged on the left and right sides. Although they are structurally integrated, they can be regarded as two drive components 50 on the left and right sides being simultaneously set on the lifting component 60, which can unlock two bottom rods 20 at the same time). This improves the synchronicity of unlocking the bottom rods 20, facilitates the smooth operation of the children's bed folding, and improves the efficiency of the children's bed folding.

[0057] In addition, the drive component 50 is slidably disposed in the sliding groove 121, which can control the moving direction of the drive component 50. At the same time, the sliding groove 121 has a certain limiting effect on the drive component 50, which can improve the stability of the drive component 50 when it moves.

[0058] It should be noted that in practical applications, the insertion hole 12 is located in the middle of the connector 10, which helps to improve the synchronization of multiple base rods 20.

[0059] In some embodiments, the sliding groove 121 is provided with a first groove segment 1211 and a second groove segment 1212. The first groove segment 1211 is disposed at the top of the second groove segment 1212, and the driving member 50 is slidably connected to the first groove segment 1211. The bottom of the lifting member 60 is provided with a limiting pin 70, and the limiting pin 70 is slidably connected to the second groove segment 1212.

[0060] By setting the limit pin 70 and the second groove 1212, the distance the drive component 50 moves downward can be controlled; when the limit pin 70 slides to the bottom of the second groove 1212, it means that the drive block has reached the designated position, and it can be seen intuitively whether the drive block has moved into place, which improves the convenience of use.

[0061] It is worth mentioning that the cooperation between the second groove section 1212 and the limiting pin 70 can also ensure the stability of the bottom of the lifting part 60, thereby improving the stability of the driving part 50 and ensuring the smooth folding of the children's bed.

[0062] In some embodiments, the base rod 20 is hinged to the connecting seat 10 via a pivot 80; the locking member 30 is provided with a guide groove 33, which extends axially along the base rod 20, the locking member 30 is inserted into the base rod 20, and the pivot 80 is inserted into the guide groove 33.

[0063] In this embodiment, the movement direction of the locking member 30 is restricted by the cooperation between the rotating shaft 80 and the guide groove 33. The locking member 30 can only move along the axial direction of the base rod 20, which improves the stability of the locking member 30 and thus improves the stability of the cooperation between the locking member 30 and the driving member 50. Furthermore, the guide groove 33 can limit the distance that the locking member 30 can move in the axial direction of the base rod 20. The displacement range of the locking member 30 can be limited by setting the length of the guide groove 33, which improves the convenience of use.

[0064] In addition, such as Figure 3 As shown, the locking member 30 is also provided with a mounting groove 34, and the bottom rod 20 is also connected with a limiting shaft 90. The limiting shaft 90 passes through the mounting groove 34, and the elastic member 40 is disposed in the mounting groove 34. One end of the elastic member 40 abuts against the limiting shaft 90, and the other end abuts against the inner wall of the mounting groove 34. By setting the limiting shaft 90, the position of the elastic member 40 can be restricted. The specific details will not be elaborated here.

[0065] In some embodiments, the locking member 30 may also be sleeved on the end of the base rod 20, but is not limited thereto.

[0066] On the other hand, this application also relates to a children's bed, including any of the aforementioned base assemblies. The children's bed also includes a railing assembly and support legs. The railing assembly includes a connecting rod and a connector. One end of the connecting rod is hinged to the connector. One end of the support leg is hinged to the end of the base rod 20 away from the connecting seat 10, and the other end is hinged to the end of the connecting rod away from the connector.

[0067] The technical solution provided in this application aims to release the locking state of the locking member 30 by using the driving member 50. The driving member 50 moves upward relative to the connecting seat 10. During the movement of the driving member 50, the driving member 50 pushes the locking member 30 to move axially along the bottom rod 20, releasing the locking of the locking member 30 by the limiting part 11 until the end of the driving member 50 near the locking member 30 is engaged in the engagement groove 31 at the end of the locking member 30. At this time, the driving member 50 and the engagement groove 31 cooperate with each other, eliminating the need for manual control of the driving member 50. The engagement groove 31 can limit the relative position of the driving member 50 and the locking member 30, reducing labor intensity and preventing the driving member 50 from slipping off the end of the locking member 30 due to gravity, external influences, or other factors, thus losing the restriction on the position of the locking member 30. The engagement groove 31 ensures that the locking member 30 is always in the unlocked state during the subsequent folding of the children's bed. The structure is simple, which is conducive to the smooth folding of the children's bed and improves the efficiency of folding the children's bed.
