Description

Technical Field

[0001] The utility model relates to the technical field of children's products, in particular to a multifunctional baby bed. Background Art

[0002] At present, baby beds have become increasingly popular among consumers in the market, and some multifunctional baby beds have also appeared, such as: the hanging bed type, the connection part can hang the bed body and swing it to be used as a rocking bed, when the bed body is removed from the connection part, it can be placed on the ground and used as a playbed. Although it has multiple functions, this product is large in size, occupies a large floor space, and when the baby bed is used, the guardrail is too high, making it inconvenient to hold and place the baby; the bottom support type bed body is adopted, the base supports the seat connection part, the connection part supports the bed body, the depth of the bed guardrail of the bed body is adjustable, when the bed body is connected to the connection part, the depth of the bed guardrail can be manually adjusted to be shorter so that it can be used as a baby bed (the depth of the EU rocking bed body is more than 220mm), when the bed body is removed from the connection part, the depth of the bed guardrail can be manually adjusted to be higher so that it can be used as a playbed (the depth of the EU playbed bed body is more than 600mm).

[0003] However, since the bed is surrounded by soft materials such as cloth, when the depth of the bed guardrail is adjusted to a shorter depth, it is necessary to use locking structures such as zippers to fold and store the soft materials in the excess depth. At this time, the following problems are likely to occur: zippers and other locking structures are prone to unlocking due to accidental operation, causing the folded and stored soft materials to sag and form cloth pockets, posing a safety hazard and failing to pass EU testing standards; the depth of the bed is not completely locked, and can be manually unlocked to increase the depth of the bed, causing the width and length of the original supporting structure to be insufficient to support the depth of the bed after the adjustment, causing a safety hazard and failing to pass EU testing standards.

[0004] Therefore, it is necessary to propose a new multifunctional baby bed to solve the above-mentioned technical problems. Utility Model Content

[0061] When the lock part is locked with the bed, the lock part drives the second limiting component to switch from the second blocking state to the second avoiding state, so that the second limiting component allows the movable frame to move closer to the fixed frame; when the lock part is unlocked with the bed, the lock part disengages from the second limiting component, and the second limiting component can be reset to the second blocking state at this time, so that the second limiting component prevents the movable frame from moving closer to the fixed frame; when the lock part is locked with the bed and the movable frame moves closer to the fixed frame, the second limiting component prevents the lock part from being unlocked with the bed.

[0062] Further, the lock portion includes a clamping member for detachably plugging with the movable frame, the second limiting assembly includes a third movable member, a ninth reset member, and a second stopper, the third movable member is movably arranged on the movable frame, the second stopper is arranged on the fixed frame or the lifting assembly, the ninth reset member is arranged between the third movable member and the movable frame, and the clamping member is provided with a first locking groove matched with the second stopper;

[0063] When the card connector is inserted into the movable frame, the card connector pushes the third movable member to move out of place, so that the third movable member is separated from the second stop block to allow the movable frame to move closer to the fixed frame, and after the movable frame moves closer to the fixed frame, the second stop block is inserted into the first locking groove to lock the card connector, thereby preventing the card connector from detaching from the movable frame; when the card connector detaches from the movable frame, the ninth reset member drives the third movable member to reset, so that the third movable member can be against the second stop block to prevent the movable frame from moving closer to the fixed frame.

[0064] Furthermore, a depth limiting rod for contacting with or separating from the movable frame is provided at the upper end of the bed frame or the lifting assembly, and the depth limiting rod contacts with the movable frame when the bed is in the first depth state.

[0065] Furthermore, the bed body also includes a guide rail, which is fixedly arranged relative to the lifting assembly, and the extension direction of the guide rail is parallel to the lifting direction of the bed frame, and the movable frame is slidably arranged on the guide rail.

[0066] Furthermore, it also includes a support part, which includes a rotating body, supporting legs, and a locking and unlocking mechanism. The rotating body is pivotally connected to the bed body, and the supporting legs are slidably arranged on the rotating body. The locking and unlocking mechanism is arranged between the rotating body and the bed body to lock the rotating body in a folded state. When the supporting legs slide outward to a preset length, the supporting legs trigger the locking and unlocking mechanism, so that the locking and unlocking mechanism releases the lock on the rotating body, thereby allowing the rotating body to rotate to an expanded state with the supporting legs.

[0067] Furthermore, the locking and unlocking mechanism includes a seventh locking block and a fourteenth reset piece. The seventh locking block is movably arranged on the rotating body, and the fourteenth reset piece is arranged between the seventh locking block and the rotating body. A first locking hole that is plugged into and cooperates with the seventh locking block is arranged on the bed body. A shift block is arranged on the supporting foot. When the supporting foot slides outward to a preset length, the shift block pushes the seventh locking block to move, so that the seventh locking block disengages from the first locking hole, thereby releasing the lock on the rotating body.

[0148] Example 1

[0149] The following is combined with Figures 1 to 15The utility model discloses a multifunctional baby bed, including: a base 1, a connecting part 2, a bed body 3, and a supporting part 4. The base 1 is used to be supported on a supporting surface, such as the ground, etc. The connecting part 2 is arranged on the base 1, and the base 1 supports the connecting part 2. The bed body 3 is detachably connected to the connecting part 2, and the connecting part 2 supports the bed body 3. The supporting part 4 is connected to the bed body 3. The connecting part 2 can be an electric drive structure or a fixed connection structure. When the connecting part 2 is an electric drive structure, the bed body 3 can be driven to move. When the connecting part 2 is a fixed connection structure, the bed body 3 is also fixed. Of course, in this embodiment, it is preferred that the connecting part 2 is an electric drive structure. It should be noted that the electric drive structure can have a swing function or a lifting function or a combination of swing and lifting functions.

[0150] In this embodiment, the bed 3 includes a first depth state and a second depth state, the depth dimension of the first depth state is smaller than the depth dimension of the second depth state, and the first depth state and the second depth state correspond to two application states of the bed 3, respectively, and specifically, the first depth state corresponds to the rocking bed position and the second depth state corresponds to the game bed position. Of course, the above is only an example, and it is not necessary to limit the first depth state to the rocking bed position and the second depth state to the game bed position; the bed 3 may also include other depth states, such as the third depth state, the fourth depth state, etc. For ease of understanding, the following will be described by taking the first depth state corresponding to the rocking bed position and the second depth state corresponding to the game bed position as an example.

[0151] The bed body 3 includes a base frame 31, a bed frame 32, a lifting assembly 33 and a software 34. The base frame 31 is used to be detachably connected to the connecting portion 2, thereby realizing a detachable connection between the bed body 3 and the connecting portion 2, and realizing locking or unlocking between the bed body 3 and the connecting portion 2. The lifting assembly 33 is connected between the base frame 31 and the bed frame 32 to adjust the relative height of the base frame 31 and the bed frame 32. The bed frame 32 and the base frame 31 are also connected through the software 34. The software 34 includes at least a first layer 341 and a second layer 342. A locking portion 35 is provided between the first layer 341 and the second layer 342. The locking portion 35 makes the first layer 341 and the second layer 342 42 is locked or unlocked, the bed body 3 is in a first depth state when the first layer 341 and the second layer 342 are brought together and locked by the locking portion 35. When the bed body 3 is in the first depth state and the bed body 3 and the connecting portion 2 are locked, the bed body 3 can be used as a rocking bed; when the first layer 341 and the second layer 342 are unlocked by the locking portion 35 and the first layer 341 is away from the second layer 342, the bed body 3 is in a second depth state. When the bed body 3 and the connecting portion 2 are unlocked and separated and the bed body 3 is in the second depth state, the support portion 4 can be used to support the bed body 3 on a support surface (such as the ground, etc.), and the support portion 4 provides support for the bed body 3, so that the bed body 3 can be used as a playbed.

[0152] See also Figures 1 to 4 , Fig.11 and Fig.14In particular, the multifunctional baby bed also includes a first linkage mechanism 5 and a second linkage mechanism 6. When the first layer 341 and the second layer 342 are brought together and locked by the lock part 35, the lock part 35 can also be locked with the bed body 3 and cooperate with the first linkage mechanism 5; when the lock part 35 is locked with the bed body 3, the first linkage mechanism 5 allows the base frame 31 and the connecting part 2 to be locked; when the lock part 35 and the bed body 3 are unlocked, the first linkage mechanism 5 prevents the base frame 31 and the connecting part 2 from being locked; when the base frame 31 and the connecting part 2 are locked, the first linkage mechanism 5 prevents the lock part 35 from being unlocked with the bed body 3 so that the first layer 341 and the second layer 342 remain locked.

[0153] The lock part 35 cooperates with the first linkage mechanism 5, which means that the lock part 35 cooperates with the first linkage mechanism 5, and can also be interpreted as the lock part 35 cooperates with the first linkage mechanism 5 to make the first linkage mechanism 5 in the following state: the first linkage mechanism 5 at this time can allow the bottom frame 31 to be locked with the connecting part 2. Further relatedly, when the bottom frame 31 is locked with the connecting part 2, the first linkage mechanism 5 can make the lock part 35 in the following state: the lock part 35 at this time cannot be unlocked from the bed body 3, so that the first layer 341 and the second layer 342 remain locked.

[0154] The support part 4 and the lifting assembly 33 are locked or unlocked with each other through the second linkage mechanism 6. When the base frame 31 is unlocked and separated from the connecting part 2 and the bed body 3 is in the second depth state, the second linkage mechanism 6 allows the support part 4 to be opened for supporting the bed body 3; when the base frame 31 is unlocked and separated from the connecting part 2 and the support part 4 is opened for use, the second linkage mechanism 6 prevents the lifting assembly 3 from shrinking so that the bed body 3 remains in the second depth state. At this time, the bed body 3 can be used as a playbed and the support part 4 provides support; when the support part 4 is folded, the second linkage mechanism 6 allows the bed body 3 to switch from the second depth state to the first depth state.

[0155] The multifunctional baby bed provided by the utility model can use the lifting assembly 33 to lower the depth of the bed body 3. After the redundant soft parts 34 are gathered together and stored, the locking part 35 can be used to lock them so that the redundant soft parts 34 cannot be unfolded to form a cloth bag, so that the bed body 3 is in the first depth state. At the same time, the locking part 35 is further locked with the bed body 3 and matched with the first linkage mechanism 5, and then the bottom frame 31 and the connecting part 2 are locked to realize the installation of the bed body 3. At this time, it is used as a rocking bed. At this time, the first linkage mechanism 5 will prevent the locking part 35 from unlocking the bed body 3, so that the first layer 341 and the second layer 342 remain locked. When the lock part 35 is unlocked from the bed body 3, the lock part 35 will not be able to cooperate with the first linkage mechanism 5. At this time, the first linkage mechanism 5 will prevent the base frame 31 from being locked with the connecting part 2, and the bed body 3 cannot be used as a rocking bed. When the base frame 31 is unlocked and separated from the connecting part 2, the first linkage mechanism 5 allows the lock part 35 to be unlocked from the bed body 3. At this time, the first layer 341 and the second layer 342 can be unlocked by the lock part 35. Under the rising action of the lifting assembly 33, the bed frame 32 rises, and the first layer 341 is away from the second layer 342, so that the bed body 3 is in a second depth state.

[0156] In this way, the multifunctional baby bed mentioned above, through the action of the first linkage mechanism 5, must first lock the lock part 35 and the bed body 3 when used as a rocking bed and cannot be unlocked manually, so that the lock part 35 cannot unlock the first layer 341 and the second layer 342 of the software 34, so that the bottom frame 31 and the bed frame 32 cannot move in the depth direction, and the depth size of the bed body 3 remains unchanged, so that the bed body 3 is always in the first depth state, and it is prevented that the first layer 341 and the second layer 342 are unlocked by the lock part 35 manually, so that the baby slides out of the bottom frame 31 or deviates from the bottom frame 31 to form a safety hazard, and at the same time, it is prevented that the first depth state in the rocking bed position is changed to the second depth state in the play bed position manually, so that the depth of the bed body 3 increases, and the base 1 is not lengthened and widened accordingly, forming a safety hazard, resulting in an over- The invention can not only avoid the disadvantages of EU safety test, but also overcome the disadvantages of making the depth dimensions of the bed body 3 of the rocking bed and the game bed the same, which makes it inconvenient to hold a baby when the rocking bed is used. It also overcomes the disadvantage that the base 1 needs to be very long and wide due to the high depth of the bed body 3 of the game bed, because only a very long and wide base 1 can pass the EU safety test and have no safety hazards. When the base frame 31 is unlocked and separated from the connecting part 2, the first linkage mechanism 5 allows the lock part 35 to be unlocked from the bed body 3, so that the lock part 35 unlocks the first layer 341 and the second layer 342, and then the depth of the base frame 31 and the bed frame 32 is manually adjusted, so that the first depth state is converted to the second depth state, so that the depth dimension requirement of the bed body 3 of the game bed is guaranteed when in the game bed position, thereby increasing the game bed function of the product, making it more cost-effective and more popular with consumers.

[0157] It should be noted that the first depth state of the bed 3 refers to the dimensional depth of the bed 3 that meets the EU safety test requirements when in the rocking bed position, and the second depth state of the bed 3 refers to the dimensional depth of the bed 3 that meets the EU safety test requirements when in the game bed position. Of course, the first state of the depth of the bed 3 may be more than one dimensional depth of the bed 3, as long as it meets the dimensional depth requirements of the rocking bed position that meet the EU safety test requirements, there can be multiple depths of the bed 3. Similarly, the second state of the depth of the bed 3 may be more than one dimensional depth of the bed 3, as long as it meets the EU safety test requirements of the bed 3 in the game bed position, there are multiple dimensional depths of the bed 3. The locking of the above-mentioned base frame 31 and the connecting part 2 can be connected and locked, and of course it can also be directly locked. It can also be understood that when the rocking bed is in use, the base frame 31 and the bed 3 will not be separated because there is no need to unlock.

[0158] At this time, it can be understood that in order to achieve locking between the bottom frame 31 of the bed body 3 and the connecting part 2, the multifunctional baby bed can also include a locking mechanism, which is arranged between the bottom frame 31 and the connecting part 2 to relatively lock the bottom frame 31 and the connecting part 2 after they are connected. Of course, since the locking mechanism is not the innovation of the present invention, any locking mechanism can be used, and this embodiment will not be described.

[0159] In addition, the above scheme is combined with a first linkage mechanism 5 and a second linkage mechanism 6. By setting the second linkage mechanism 6, when the base frame 31 is unlocked and separated from the connecting portion 2, the depth of the bed body 3 must be adjusted to the second depth state before the support portion 4 is allowed to be supported on the support surface (such as the ground, etc.) so that the bed body 3 is in the game bed position and used as a game bed, thereby overcoming the risk that when the bed body 3 is not in the second depth state, the support portion 4 is supported on the support surface and is manually operated to be used as a game bed, which fails to pass the EU safety test requirements and poses a safety hazard; at the same time, when the bed body 3 is in the second depth state and when the support portion 4 is supported on the support surface, the second linkage mechanism 6 makes the bed body 3 always in the second depth state, that is, the base frame 31 and the bed frame 32 cannot change in depth, that is, at this time, the depth of the bed body 3 will never change. It is impossible to change to a size that does not meet the depth dimension requirements of the game bed body 3, thereby overcoming the disadvantages of manually adjusting the depth of the base frame 31 and the bed frame 32 to adjust the bed body 3 from the second depth state to the first depth state or the depth dimension of the bed body 3 that does not meet the EU safety test requirements when the support part 4 is supported on the support surface for use as a game bed; when the support part 4 leaves the support surface, the second linkage mechanism 6 allows the second depth state of the bed body 3 to change and can be converted to the first depth state or other depth states of the bed body 3, so that the bed body 3 meets the EU safety test standards when used as a game bed and has no safety hazards. At the same time, when it is not used as a game bed and needs to be used as a rocking bed, it can be converted to the rocking bed position, so that the bed body 3 is in the first depth state, thereby ensuring the safety of use as a rocking bed, thereby making the product cost-effective, multi-functional, small in size and low in cost.

[0160] In this embodiment, the first linkage mechanism 5 is disposed on the base frame 31 or the lifting assembly 33, or the first linkage mechanism 5 is disposed between the base frame 31 and the connecting portion 2, or the first linkage mechanism 5 is disposed between the lifting assembly 33 and the connecting portion 2, the first linkage mechanism 5 cooperates with the connecting portion 2, and the locking portion 35 can be locked with the base frame 31 or the lifting assembly 33. Preferably, the first linkage mechanism 5 is disposed on the base frame 31, and the locking portion 35 can be locked with the base frame 31, so that the various components can be hidden conveniently and the overall appearance is more beautiful.

[0161] Preferably, the base frame 31 is provided with a mounting seat 36 for locking or unlocking with the connecting portion 2, and the first linkage mechanism 5 includes a bidirectional locking portion 51, which prevents the mounting seat 36 from locking with the connecting portion 2 when the locking portion 35 is unlocked with the bed body 3; when the locking portion 35 is locked with the bed body 3, the bidirectional locking portion 51 allows the mounting seat 36 to lock with the connecting portion 2, and when the mounting seat 36 is locked with the connecting portion 2, the bidirectional locking portion 51 prevents the locking portion 35 from unlocking with the base frame 31 or the lifting assembly 33. The bidirectional locking of the locking portion 35 and the connecting portion 2 is achieved by the bidirectional locking portion 51, the functional integration is high, the functional modularization is convenient, the occupied volume of the first linkage mechanism 5 is controlled, and the cost is reduced.

[0162] More preferably, the first linkage mechanism 5 also includes a blocking portion 52, and the blocking portion 52 and the two-way locking portion 51 are respectively movably arranged on the mounting seat 36, and the locking portion 35, the two-way locking portion 51 and the blocking portion 52 cooperate with each other, and the two-way locking portion 51 also cooperates with the connecting portion 2. Specifically, the locking portion 35 cooperates with the two-way locking portion 51, and the locking portion 35 also cooperates with the blocking portion 52, and the two-way locking portion 51 cooperates with the blocking portion 52, and the two-way locking portion 51 also cooperates with the connecting portion 2. Among them, when the locking part 35 is locked with the bed body 3, the locking part 35 drives the blocking part 52 to move and make way, and the blocking part 52 releases the movement restriction of the two-way locking part 51 so that the two-way locking part 51 can move relative to the mounting seat 36, thereby allowing the mounting seat 36 to be locked with the connecting part 2; when the mounting seat 36 is locked with the connecting part 2, the connecting part 2 drives the two-way locking part 51 to move to form an obstruction to the locking part 35, so that the two-way locking part 51 prevents the locking part 35 from being unlocked from the bed body 3.

[0163] More preferably, a matching portion 361 is further provided on the mounting seat 36 , and the locking portion 35 can be locked or unlocked with the matching portion 361 to achieve locking or unlocking between the locking portion 35 and the bed body 3 , and the bidirectional locking portion 51 can also prevent the locking portion 35 from unlocking with the matching portion 361 .

[0164] See also Figures 6 to 10As a preferred specific example, the mounting seat 36 is provided with a first mounting groove 362, a side hole 363, a first slide groove 364, and a second slide groove 365. The matching portion 361 includes a first clamping position 3611 and a first plug hole 3612. The first clamping position 3611 and the first plug hole 3612 are also provided on the mounting seat 36. Specifically, the mounting seat 36 includes a first seat body 366 and a second seat body 367. The first seat body 366 and the second seat body 367 are fixedly connected to the bottom frame 31 at intervals. The first mounting groove 362 and the side hole 363 can be specifically provided on the first seat body 366. The first slide groove 364, the second slide groove 365, the first clamping position 3611 and the first plug hole 3612 can be specifically provided on the second seat body 367. Of course, the mounting seat 36 can also be A whole; wherein the first mounting groove 362 is used to insert the connecting part 2, the side hole 363 is connected to the first mounting groove 362, the two-way locking part 51 includes a latch 511, a first reset member 512 and a first transmission member 513, the latch 511 is slidably arranged in the side hole 363, and one end of the latch 511 penetrates into the first mounting groove 362, the other end of the latch 511 is connected to one end of the first transmission member 513, the first reset member 512 is connected between the latch 511 and the mounting seat 36, and the other end of the first transmission member 513 is used to cooperate with the blocking lock part 35 to prevent the locking part 35 from detaching from the bed body 3, preferably, the first transmission member 513 is slidably arranged on the first slide groove 364, and the sliding direction of the first transmission member 513 is opposite to the sliding direction of the latch 511 The locking portion 35 is preferably a zipper structure. Specifically, the locking portion 35 includes two chain belts 351, a pull head 352, and a clamping member 353. The two chain belts 351 are respectively connected to the first layer 341 and the second layer 342. The pull head 352 and the clamping member 353 are connected to the first layer 341 and the second layer 342. When the chain belt 351 cooperates and the first layer 341 and the second layer 342 are brought together, the first layer 341 and the second layer 342 can be locked in the brought together state by pulling the slider 352. The snap-fitting member 353 is connected to the slider 352. The snap-fitting member 353 is used to connect with the matching portion 361 and can be used to push the first stop block 521 to slide, and can be restricted by the first transmission member 513. The snap-fitting member 353 can be specifically provided with a first slot 355 for cooperating with the first clamping position 3611 and a first protrusion 354 for cooperating with the first socket 3612, wherein a space allowing the snap-fitting member 353 to drive the first stop block 521 to slide and a space for the first protrusion 354 to be inserted into the first socket 3612 needs to be reserved between the first clamping position 3611 and the first slot 355.

[0165] Wherein, the first elastic member and the second elastic member are preferably springs. Of course, in other examples, the first elastic member and the second elastic member can also adopt structures such as tension springs and spring sheets to provide a restoring force.

[0166] When used specifically, Fig.10 The direction shown is for reference. After the first layer 341 and the second layer 342 are locked in the closed state by pulling the pull head 352, the clamping member 353 can drive the first stopper 521 to slide upward and compress the second elastic member, so that the lower surface of the first stopper 521 is higher than the upper surface of the other end of the first transmission member 513, so that the first stopper 521 cannot prevent the first transmission member 513 from sliding. Then the first protrusion 354 on the clamping member 353 is aligned and inserted into the first insertion hole 3612 to form a lock, so as to prevent the clamping member 353 from moving downward and disengaging under the action of the second elastic member and causing accidental unlocking. At the same time, the lower surface of the clamping member 353 will also be higher than the upper surface of the other end of the first transmission member 513. Then the first mounting groove 362 is aligned with the connecting frame 21 of the connecting part 2. During the process of inserting the connecting frame 21 into the first mounting groove 362, the connecting frame 21 can drive the latch 511 to slide and compress the first elastic member and prevent the latch 511 from resetting. The latch 511 drives the first transmission member 513 to slide at the same time, so that The other end of the first transmission member 513 slides to the bottom of the clamping member 353, so that the other end of the first transmission member 513 can be used to prevent the clamping member 353 from moving downward and disengaging to complete the unlocking; when it is necessary to unlock the clamping member 353, the connecting frame 21 must first be disengaged from the first mounting groove 362 to release the resistance to the latch 511. The latch 511 can then be reset under the action of the first elastic member, so that the latch 511 drives the first transmission member 513 to slide and reset, so that the first transmission member The other end of 513 is detached from the clamping member 353, and then the clamping member 353 can be removed. After the clamping member 353 is removed, the lock on the first stop block 521 will be released. At this time, the first stop block 521 can be reset under the action of the second elastic member, so that the first stop block 521 can be blocked by the other end of the first transmission member 513. In this way, the sliding of the pin 511 can be restricted in the reverse direction. At this time, the pin 511 can be blocked by the connecting frame 21 of the connecting part 2, so that the mounting seat 36 cannot be locked with the connecting part 2.

[0167] It should be noted that the first clamping position 3611 and the first clamping slot 355 can also be interchanged, such as the first clamping position 3611 is set on the clamping member 353, and the first clamping slot 355 is correspondingly set on the mounting seat 36; the first plug hole 3612 and the first protrusion 354 can also be interchanged, such as the first plug hole 3612 is set on the clamping member 353, and the first protrusion 354 is correspondingly set on the mounting seat 36. That is, the matching portion 361 can also include the first clamping slot 355 and the first clamping slot 355 and the first protrusion 354, or the first clamping position 3611 and the first protrusion 354.

[0168] It should be noted that the bidirectional locking part 51 can also adopt other structures that can realize bidirectional locking of the lock part 35 and the connecting part 2. For example, the first transmission member 513 can also be rotatably connected to the mounting seat 36. In this case, the latch 511 can be used to drive the first transmission member 513 to rotate, and the first stopper 521 is used to prevent the first transmission member 513 from rotating; or, the bidirectional locking part 51 can also adopt a structure of a pull rope combined with two locking parts, such as one locking part cooperates with the lock part 35, and the other locking part cooperates with the connecting part 2, and the pull rope acts between the two locking parts. When the first locking part cooperates with the lock part 35, the locking part drives the second locking part through the pull rope so that the connecting part 2 can be locked with the mounting seat 36. Conversely, when the connecting part 2 is locked with the mounting seat 36, the first locking part can prevent the lock part 35 from being unlocked from the bed body 3. In addition, the blocking part can also adopt other structures that can realize limiting the bidirectional locking part 51 and be driven by the lock part 35. For example, the first stopper 521 may also be rotatably connected to the mounting seat 36. In this case, the first stopper 521 blocks the other end of the first transmission member 513 when rotating and resetting. When the clamping member 353 is connected to the matching portion 361, the first stopper 521 can be driven to rotate and disengage from the first transmission member 513, so that the first stopper 521 releases the restriction on the first transmission member 513. Since a specific solution has been clearly disclosed, the structures of other bidirectional locking portions 51 and blocking portions that can achieve the same purpose will not be described here.

[0169] See also Figures 11 to 15In this embodiment, the second linkage mechanism 6 includes a first locking portion 61, a second locking portion 62, and a first transmission portion 63. The first locking portion 61 is used to lock or unlock the support portion 4 and the base frame 31 or the lifting assembly 33. The second locking portion controls the locking or unlocking of the bed frame 32 and the base frame 31 through the lifting assembly 33. The first transmission portion 63 is used to act on the first locking portion 61 when the bed body 3 is converted from the first depth state to the second depth state, so that the first locking portion 61 releases the lock on the support portion 4, thereby allowing the support portion 4 to be opened for supporting the bed body 3 for use; the first transmission portion 63 is used to act on the second locking portion 62 when the support portion 4 is opened for use, so that the second locking portion 62 locks the lifting assembly 33 so that the bed body 3 remains in the second depth state.

[0170] In this way, the first locking portion 61 is used to achieve locking or unlocking between the support portion 4 and the base frame 31 or the lifting assembly 33, and the second locking portion is used to control the locking or unlocking of the bed frame 32 and the base frame 31 through the lifting assembly 33, and the state change is achieved through the transmission of the first transmission portion 63, so that only when the bed body 3 is in the second depth state can the support portion 4 be allowed to be supported on the supporting surface (such as the ground, etc.) so that the bed body 3 is in the game bed position and used as a game bed, and when the game bed is in use, the bed body 3 is locked in the second depth state, which has high safety and can pass EU testing standards.

[0171] Preferably, the lifting assembly 33 includes a first connecting rod 331 and a second connecting rod 332 which are relatively slidably connected and can be relatively locked or unlocked, the first connecting rod 331 is connected to the bed frame 32, the second connecting rod 332 is connected to the base frame 31, the first transmission part 63 includes a second transmission member 631 and a third transmission member 632, the second locking part 62 is arranged on the first connecting rod 331, the first locking part 61 is arranged on the second connecting rod 332 or the base frame 31, the second transmission member 631 is connected between the second locking part 62 and the support part 4, and the third transmission member 632 is connected to the first Between the locking portion 61 and the first connecting rod 331; when the bed body 3 is in the second depth state, the first connecting rod 331 releases the locking of the support portion 4 by the first locking portion 61 through the third transmission member 632, thereby allowing the support portion 4 to be opened for supporting the bed body 3 for use; when the first connecting rod 331 and the second connecting rod 332 are locked and the bed body 3 is in the second depth state, when the support portion 4 is opened for use, the support portion 4 prevents the first connecting rod 331 and the second connecting rod 332 from being unlocked through the second transmission member 631, thereby keeping the bed body 3 in the second depth state.

[0172] It should be noted that a locking pin structure 333 is provided between the first connecting rod 331 and the second connecting rod 332 for locking the bed body 3 in the first depth state or the second depth state. The locking pin structure 333 can realize the locking or unlocking between the first connecting rod 331 and the second connecting rod 332. The locking pin structure 333 belongs to the prior art, and the relevant descriptions of other lifting and locking documents can be referred to. This article will not elaborate on it here. In addition, other locking structures can be used between the first connecting rod 331 and the second connecting rod 332 to realize the locking or unlocking between the first connecting rod 331 and the second connecting rod 332.

[0173] See also Figures 11 to 15 As a preferred specific example, the first locking portion 61 includes a first locking block 611 and a third elastic member 612. The first locking block 611 is slidably disposed on the second connecting rod 332. The second transmission member 631 is a pull rope and is connected between the first locking block 611 and the first connecting rod 331. The support portion 4 is pivotally connected to the lower portion of the second connecting rod 332. A second card slot 41 is provided on the support portion 4. When the support portion 4 is in the rotationally retracted position, the first locking block 611 is aligned with the second card slot 41, and the first locking block 611 can be clamped to the second card slot 41 under the action of the third elastic member 612, thereby locking the support portion 4 in the rotationally retracted position. When the first connecting rod 331 rises so that the bed body 3 is in the second depth state, the first connecting rod 331 can pull the first locking block 611 out of the second card slot 41 through the second transmission member 631, thereby releasing the lock on the support portion 4. The second locking portion 62 includes a second locking block 621 and a fourth elastic member 622. The second locking block 621 is slidably disposed on The first connecting rod 331 and the third transmission member 632 are also pull ropes and are connected between the second locking block 621 and the support part 4. When the first connecting rod 331 rises so that the bed body 3 is in the second depth state and the support part 4 rotates to the open position, the support part 4 can release the tension on the third transmission member 632, so that the third transmission member 632 releases the tension applied to the second locking block 621, and the second locking block 621 can slide and reset under the reset action of the fourth elastic member 622, so that the second locking block 621 locks the locking pin structure 333, so that the locking pin structure 333 cannot be unlocked, thereby keeping the first connecting rod 331 and the second connecting rod 332 locked, thereby keeping the bed body 3 in the second depth state. When the support part 4 is in the rotationally retracted position, the support part 4 can pull the second locking block 621 to slide and compress the fourth elastic member 622 through the third transmission member 632, so that the second locking block 621 releases the lock of the locking pin structure 333, thereby releasing the lock of the lifting assembly 33.

[0174] It should also be explained that the first locking portion 61 and the second locking portion 62 may also adopt other structures that can achieve locking and unlocking of the support portion 4 and the lifting assembly 33. Since the innovation of the utility model does not lie in the specific structure of the first locking portion 61 and the second locking portion 62 and a specific scheme has been clearly disclosed, other structures of the first locking portion 61 and the second locking portion 62 that can achieve the same purpose will not be elaborated here.

[0175] Example 2

[0176] See also Figures 16 to 22 This embodiment also discloses a multifunctional baby bed. The difference between this embodiment and Embodiment 1 lies in: the second linkage mechanism 6 and the support part 4 are different.

[0177] It should be noted that this embodiment is the same as Embodiment 1, and both include a second linkage mechanism 6 and a support portion 4, wherein the support portion 4 is connected to the bed body 3; when the bed body 3 is in the second depth state, the second linkage mechanism 6 can allow the support portion 4 to be supported on the support surface for use, and at the same time, the second linkage mechanism 6 can prevent the lifting assembly 33 from shrinking so that the bed body 3 remains in the second depth state.

[0178] Here, allowing the support parts 4 to be supported on the support surface for use means that all the support parts 4 can be normally supported on the support surface, thereby providing support for the bed body 3 and maintaining the stable use of the bed body 3.

[0179] Different from Example 1, in this embodiment, the second linkage mechanism 6 cooperates with the lifting assembly. Specifically, the second linkage mechanism 6 is arranged between the support part 4 and the lifting assembly 33. When the bed 3 is in the second depth state and the support part 4 is supported on the support surface, the second linkage mechanism 6 is triggered, so that the second linkage mechanism 6 prevents the lifting assembly 33 from shrinking so that the bed 3 remains in the second depth state.

[0180] That is, the support part 4 of this embodiment can be fixed, and does not need to be a rotating support part 4 like the first embodiment.

[0181] Thus, in the above scheme, the multifunctional baby bed of the present embodiment adjusts the depth of the bed body 3 to the second depth state, and utilizes the function of the second linkage mechanism 6, when the support portion 4 is supported on the support surface (such as the ground, etc.) so that the bed body 3 is in the play bed position when the play bed is used, the second linkage mechanism 6 is also utilized to prevent the contraction of the lifting assembly 33 so that the bed body 3 remains in the second depth state, so that the depth cannot be adjusted when the play bed is used, thereby overcoming the disadvantages of manually adjusting the depth of the base frame 31 and the bed frame 32 to adjust the bed body 3 from the second depth state to the first depth state or the depth size of the bed body 3 that does not meet the EU safety test requirements when the support portion 4 is supported on the support surface to be used as a play bed, so that the bed body 3 meets the EU safety test standards when used as a play bed without safety hazards.

[0182] See also Figures 17 to 22 In this embodiment, preferably, the second linkage mechanism 6 includes a first trigger portion 64, a third locking portion 65, and a second transmission portion 66. The first trigger portion 64 is arranged on the support portion 4 and is used to resist the support surface. The third locking portion 65 is arranged on the lifting component 33 and controls the locking or unlocking of the bed frame 32 and the base frame 31 through the lifting component 33. The second transmission portion 66 is connected between the first trigger portion 64 and the third locking portion 65; when the first trigger portion 64 is pushed and moved by the support surface, the support portion 4 is normally supported on the support surface. At the same time, the first trigger portion 64 acts on the third locking portion 65 through the second transmission portion 66, so that the third locking portion 65 locks the lifting component 33 so that the bed body 3 remains in the second depth state.

[0183] In the above scheme, in the process of placing the support part 4 on the support surface, the support surface is used to push the first trigger part 64 to move, so that the support part 4 can be normally supported on the support surface. At the same time, the movement of the first trigger part 64 can act on the third locking part 65 through the second transmission part 66, so that the state of the third locking part 65 changes, so that the third locking part 65 locks the lifting assembly 33 so that the bed body 3 remains in the second depth state. In this way, the bed body 3 is in the game bed position and used as a game bed, and the bed body 3 is locked in the second depth state when the game bed is in use. It has high safety and can pass EU testing standards.

[0184] See also Fig.18 , Fig.19 , Fig.21 and Fig. 22As a preferred specific example, the lifting assembly 33 of this embodiment also includes a first connecting rod 331 and a second connecting rod 332 that are relatively slidably connected and can be relatively locked or unlocked. The first connecting rod 331 is connected to the bed frame 32, and the second connecting rod 332 is connected to the base frame 31. A locking pin structure 333 for locking the bed body 3 in the first depth state or the second depth state is provided between the first connecting rod 331 and the second connecting rod 332. The locking pin structure 333 can realize the locking or unlocking between the first connecting rod 331 and the second connecting rod 332. The locking pin structure 333 belongs to the prior art, and the relevant descriptions of other lifting and locking documents can be referred to. This article will not elaborate on it here. In addition, other locking structures can be used between the first connecting rod 331 and the second connecting rod 332 to realize the locking or unlocking between the first connecting rod 331 and the second connecting rod 332.

[0185] In addition, in this specific example, the first trigger part 64 includes a first slider 641 and a fifth elastic member 642. The first slider 641 is slidably disposed on the support part 4 and can slide out from the bottom of the support part 4. The fifth elastic member 642 is disposed between the first slider 641 and the support part 4. The third locking part 65 includes a third locking block 651 and a sixth elastic member 652. The third locking block 651 is movably disposed on the first connecting rod 331. The sixth elastic member 652 is disposed between the third locking block 651 and the first connecting rod 331. The second transmission part 66 includes a fourth transmission member, which is a pull rope and is connected between the first slider 641 and the third locking block 651. Specifically, the support part 4 can be fixedly connected to the bottom of the second connecting rod 332, or the support part 4 can be fixedly connected to the bottom of the base frame 31. The support portion 4 is preferably a hollow structure to facilitate the installation of the first trigger portion 64 and the second transmission portion 66. A fastener 42 and a shaft 43 are provided on the support portion 4. The fastener 42 is used to provide support for the fifth elastic member 642, and the shaft 43 is used to surround the fourth transmission member. The fourth transmission member can be passed through the support portion 4 and enter the second connecting rod 332 and connected to the third locking block 651. The third locking block 651 can be specifically rotatably set at the lower end of the first connecting rod 331. In particular, the third locking block 651 is located below the locking pin structure 333; when the first slider 641 is pushed by the supporting surface to slide and shrink into the support portion 4, the first slider 641 drives the third locking block 651 to move through the fourth transmission member, so that the third locking block 651 locks the locking pin structure 333, thereby keeping the bed 3 in the second depth state.

[0186] To be more specific, the fifth elastic member 642 and the sixth elastic member 652 are preferably springs. When the first slider 641 is pushed by the support surface to slide and shrink into the support part 4, the first slider 641 can compress the fifth elastic member 642. The first slider 641 also pushes one end of the fourth transmission member to move upward. Through the action of the shaft 43, a pulling effect is generated on one end of the fourth transmission member, so that the other end of the fourth transmission member pulls the third locking block 651 to rotate. After the third locking block 651 rotates, it can be inserted into the rear side of the locking pin structure 333, so that the third locking block 651 locks the locking pin structure 333, so that the locking pin structure 333 cannot be unlocked, thereby keeping the first connecting rod 331 and the second connecting rod 332 locked, thereby keeping the bed body 3 in the second depth state. When the support portion 4 is separated from the support surface, the support surface no longer acts on the first slider 641, and the first slider 641 is reset under the elastic force of the fifth elastic member 642. When the first slider 641 is reset, the pull on the fourth transmission member is released, so that the fourth transmission member releases the pull on the third locking block 651. The third locking block 651 rotates and resets under the elastic force of the sixth elastic member 652, so that the third locking block 651 leaves the rear side of the locking pin structure 333, thereby unlocking the locking pin structure 333, thereby allowing the first connecting rod 331 and the second connecting rod 332 to be unlocked, thereby allowing the depth state of the bed 3 to be adjusted.

[0187] It should be noted that in other preferred embodiments, the support portion 4 may also be rotatably connected to the second connecting rod 332 or the base frame 31 , which does not affect the function of the second linkage mechanism 6 .

[0188] Example 3

[0189] See also Figure 23 to Figure 28 This embodiment also discloses a multifunctional baby bed. The difference between this embodiment and Embodiment 1 or 2 is that the second linkage mechanism 6 is different.

[0190] It should be noted that this embodiment is the same as Embodiment 1 or 2, and both include a second linkage mechanism 6 and a support portion 4, wherein the support portion 4 is connected to the bed body 3; when the bed body 3 is in the second depth state, the second linkage mechanism 6 can allow the support portion 4 to be supported on the support surface for use, and at the same time, the second linkage mechanism 6 can prevent the lifting assembly 33 from shrinking so that the bed body 3 remains in the second depth state.

[0191] Different from Embodiment 1 or 2, in this embodiment, the second linkage mechanism 6 cooperates with the lifting assembly 33, and the second linkage mechanism 6 can be used to resist or disengage from the support surface. When the bed 3 is in the second depth state, the second linkage mechanism 6 can disengage from the support surface to allow the support part 4 to be supported on the support surface for use. At the same time, the second linkage mechanism 6 prevents the lifting assembly 33 from shrinking so that the bed 4 remains in the second depth state.

[0192] Thus, in the above scheme, the multifunctional baby bed of the present embodiment can adjust the second linkage mechanism 6 after adjusting the depth of the bed body 3 to the second depth state, so that the second linkage mechanism 6 is separated from the support surface, thereby allowing the support portion 4 to be supported on the support surface (such as the ground, etc.) so that the bed body 3 is in the play bed position and used as a play bed. At the same time, the second linkage mechanism 6 is used to prevent the contraction of the lifting assembly 33 so that the bed body 3 remains in the second depth state, so that the depth cannot be adjusted when the play bed is used, thereby overcoming the disadvantages of manually adjusting the depth of the base frame 31 and the bed frame 32 to adjust the bed body 3 from the second depth state to the first depth state or the depth size of the bed body 3 that does not meet the EU safety test requirements when the support portion 4 is supported on the support surface to be used as a play bed, so that the bed body 3 meets the EU safety test standards when used as a play bed and has no safety hazards.

[0193] It should be noted that the support part 4 of this embodiment can be fixedly connected to the base frame 31 or the second connecting rod 332, or can be rotatably connected to the base frame 31 or the second connecting rod 332. This embodiment does not limit the connection method and connection object of the support part 4.

[0194] As a preferred specific example, similar to Embodiment 1 or 2, the lifting assembly 33 of this embodiment also includes a first connecting rod 331 and a second connecting rod 332 that are relatively slidably connected and can be relatively locked or unlocked, the first connecting rod 331 is connected to the bed frame 32, the second connecting rod 332 is connected to the base frame 31, and a locking pin structure 333 for locking the bed body 3 in the first depth state or the second depth state is provided between the first connecting rod 331 and the second connecting rod 332. The locking pin structure 333 can realize the locking or unlocking between the first connecting rod 331 and the second connecting rod 332. The locking pin structure 333 belongs to the prior art, and the relevant descriptions of other lifting and locking documents can be referred to, which will not be elaborated in this article. In addition, other locking structures can be used between the first connecting rod 331 and the second connecting rod 332 to realize the locking or unlocking between the first connecting rod 331 and the second connecting rod 332.

[0195] See also Figure 23 to Figure 28 In this embodiment, preferably, the second linkage mechanism 6 includes a rotating portion 67 , a fourth locking portion 68 , a fifth locking portion 69 , a third transmission portion 70 , and a fourth transmission portion 71 .

[0196] The rotating part 67 can be rotatably arranged on the lifting assembly 33. Specifically, the rotating part 67 is rotatably arranged on the lower end of the second connecting rod 332. Of course, the rotating part 67 can also be rotatably arranged on the base frame 31 or the supporting part 4, so that the rotating part 67 can be rotated to open so as to abut against the supporting surface or rotated to be retracted so as to be separated from the supporting surface. The function of the rotating part 67 is as follows: when the rotating part 67 is rotated to open, it can contact the supporting surface before the supporting part 4, so that the supporting part 4 cannot be normally supported on the supporting surface; when the rotating part 67 is rotated to be retracted, it will not form an obstacle, and the supporting part 4 can be normally supported on the supporting surface.

[0197] Among them, the fourth locking part 68 is arranged on the lifting component 33 and controls the locking or unlocking of the bed frame 32 and the base frame 31 through the lifting component 33. The third transmission part 70 is connected between the rotating part 67 and the fourth locking part 68. When the rotating part 67 rotates away from the supporting surface, it allows the supporting part 4 to be supported on the supporting surface for use. At the same time, the rotating part 67 acts on the fourth locking part 68 through the third transmission part 70, so that the fourth locking part 68 locks the lifting component 33 so that the bed body 3 remains in the second depth state.

[0198] Among them, the fifth locking portion 69 is used to lock or unlock the rotating portion 67 and the lifting assembly 33 or the base frame 31 or the support portion 4, and the fourth transmission portion 71 is connected between the fourth locking portion 68 and the fifth locking portion 69. When the bed body 3 is converted from the first depth state to the second depth state, the fourth locking portion 68 acts on the fifth locking portion 69 through the fourth transmission portion 71, so that the fifth locking portion 69 releases the lock on the rotating portion 67, thereby allowing the rotating portion 67 to rotate away from the support surface, thereby allowing the support portion 4 to be supported on the support surface for use.

[0199] In the above scheme, in the process of using the bed body 4 as a playbed, it is necessary to first adjust the bed body 4 to the second depth state through the lifting assembly 33. At this time, the lifting assembly 33 can act on the fifth locking part 69 through the fourth transmission part 71, so that the fifth locking part 69 unlocks the rotating part 67, and then the rotating part 67 can be manually driven to rotate and retract, so as to allow the support part 4 to be normally supported on the support surface. When the rotating part 67 rotates and retracts, the rotating part 67 can act on the fourth locking part 68 through the third transmission part 70, so that the fourth locking part 68 locks the lifting assembly 33 so that the bed body 3 remains in the second depth state. In this way, the bed body 3 is in the playbed position and used as a playbed, and the bed body 3 is locked in the second depth state when the playbed is used, which is highly safe and can pass the EU test standards. At the same time, the fifth locking portion 69 and the fourth transmission portion 71 can also be used to lock the rotating portion 67 when the bed body 4 is not in the second depth state, so that the rotating portion 67 can maintain contact with the support surface before the support portion 4, thereby making it impossible for the support portion 4 to be normally supported on the support surface, that is, when the bed body 4 is not in the second depth state, the support portion 4 cannot be normally supported on the support surface, so as to further improve the safety of use.

[0200] See also Figure 26 to Figure 28 As a preferred specific example, the rotating portion 67 is rotatably connected to the lower side of the second connecting rod 332, a third card slot 671 is provided on the rotating portion 67, the fourth locking portion 68 includes a fourth locking block 681 and a seventh elastic member 682, the seventh elastic member 682 is preferably a spring, the fourth locking block 681 is rotatably arranged on the first connecting rod 331 and corresponds to the position of the locking pin structure 333, the seventh elastic member 682 is arranged between the fourth locking block 681 and the first connecting rod 331, the third transmission portion 70 includes a fourth transmission member, the fourth transmission member is a pull rope and is connected between the rotating portion 67 and the fourth locking block 681; when the rotating portion 67 is rotated to open, the locking pin 331 is released. The pulling of the fourth transmission member causes the fourth transmission member to release the pulling on the fourth locking block 681, and the fourth locking block 681 is reset to the rear side of the locking pin structure 333 under the elastic force of the seventh elastic member 682, thereby releasing the lock on the locking pin structure 333; when the rotating part 67 rotates and retracts, it pulls the fourth transmission member, so that the fourth transmission member pulls the fourth locking block 681, and the fourth locking block 681 compresses the seventh elastic member 682 and moves upward to insert into the rear side of the locking pin structure 333, thereby locking the locking pin structure 333, thereby preventing the locking pin structure 333 from unlocking the first connecting rod 331 and the second connecting rod 332, so that the bed 3 can be kept in the second depth state.

[0201] The fifth locking portion 69 includes a fifth locking block 691 and an eighth elastic member 692. The fifth locking block 691 is used to engage with the third card slot 671. The eighth elastic member 692 is preferably a spring. The fifth locking block 691 is slidably arranged on the second connecting rod 332 and corresponds to the position of the rotating portion 67. Specifically, when the rotating portion 67 is in the rotationally retracted position, the fifth locking block 691 is aligned with the third card slot 671 of the rotating portion 67. The eighth elastic member 692 is arranged between the fifth locking block 691 and the second connecting rod 332. The fourth transmission portion 71 includes a fifth transmission member, which is a pull rope and is connected between the first connecting rod 331 and the fifth locking block 691. When the first connecting rod 331 rises and makes the bed body 3 in the second depth state, , the first connecting rod 331 pulls the fifth transmission member, so that the fifth transmission member pulls the fifth locking block 691 to compress the eighth elastic member 692 and slide upward to disengage from the third slot 671 of the rotating part 67, thereby releasing the lock of the rotating part 67. At this time, the rotating part 67 can rotate under the action of external force; when the rotating part 67 is in the rotational open position and the first connecting rod 331 descends so that the bed body 3 is in the first depth state, the first connecting rod 331 releases the pull on the fifth transmission member, so that the fifth transmission member releases the pull on the fifth locking block 691, and the fifth locking block 691 is reset under the elastic force of the eighth elastic member 692, so that the fifth locking block 691 is clamped to the third slot 671, thereby locking the rotating part 67 in the rotational open position.

[0202] It should also be explained that the fourth locking portion 68 and the fifth locking portion 69 may also adopt other structures that can achieve locking and unlocking of the rotating portion 67 and the lifting assembly 33. Since the innovation of the utility model does not lie in the specific structure of the fourth locking portion 68 and the fifth locking portion 69 and a specific scheme has been clearly disclosed, the structures of the fourth locking portion 68 and the fifth locking portion 69 that can achieve the same purpose will not be elaborated here.

[0203] Based on the above description, the solutions of the second linkage mechanism 6 in Embodiment 1, Embodiment 2 and Embodiment 3 of the present invention are the same in that:

[0204] The second linkage mechanism 6 has at least the following first function: when the bed body 3 is used as a game bed, the bed body 3 is kept in the second depth state. Specifically, when the bed body 3 is in the second depth state, the second linkage mechanism 6 can allow the support part 4 to be supported on the support surface for use. At the same time, the second linkage mechanism 6 prevents the lifting assembly 33 from shrinking so that the bed body 3 remains in the second depth state.

[0205] The difference is:

[0206] (1) In Example 1, the support portion 4 is movably arranged, and the second linkage mechanism 6 is linked with the support portion 4 and the lifting assembly 33. The second linkage mechanism 6 allows the support portion 4 to be opened or folded when the bed body 3 is in the second depth state. When the support portion 4 is opened and used, the second linkage mechanism 6 prevents the lifting assembly 33 from shrinking so that the bed body 3 remains in the second depth state. When the support portion 4 is folded, the second linkage mechanism 6 allows the bed body 3 to switch from the second depth state to the first depth state;

[0207] (2) In Example 2, the second linkage mechanism 6 cooperates with the lifting assembly 33. When the bed 3 is in the second depth state and the support portion 4 is supported on the support surface, the second linkage mechanism 6 is triggered, so that the second linkage mechanism 6 prevents the lifting assembly 33 from shrinking so that the bed 3 remains in the second depth state;

[0208] (3) In Example 3, the second linkage mechanism 6 cooperates with the lifting assembly 33, and the second linkage mechanism 6 can be used to resist or disengage from the support surface. When the bed 3 is in the second depth state, the second linkage mechanism 6 can be disengaged from the support surface to allow the support portion 4 to be supported on the support surface for use. At the same time, the second linkage mechanism 6 prevents the lifting assembly 33 from shrinking so that the bed 3 remains in the second depth state.

[0209] It should also be noted that the multifunctional baby beds of Embodiment 1, Embodiment 2 and Embodiment 3 can be used as play beds without disassembling the bed body 3, that is, there is no need to unlock and separate the bed body 3 from the connecting portion 2. At this time, the supporting portion 4 can be changed, such as making the supporting portion 4 lowered and supported on the supporting surface, so that the supporting portion 4 can be used to provide support for the bed body 3; or, the bed body 3 and the supporting portion 4 can be lowered as a whole, that is, the connecting portion 2 or the base 1 can be changed to lower the bed body and the supporting portion 4 as a whole, so that the supporting portion 4 is supported on the supporting surface, so that the supporting portion 4 can be used to provide support for the bed body 3.

[0210] It should also be noted that, when the multifunctional baby bed of the utility model is used when the bed body 3 is placed on the support surface, that is, when it is supported on the support surface by the support part 4, the depth of the bed body 3 can also be other depth states, and it is not limited to being placed on the support surface in the second depth state. The function of the second linkage mechanism 6 of the utility model can satisfy that when the bed body 3 is in the second depth state and is normally supported on the support surface by the support part 4, the second linkage mechanism 6 can lock the lifting assembly 33, so that the bed body 3 remains in the second depth state and its depth cannot be adjusted.

[0211] It should also be noted that allowing the support part 4 to be supported on the support surface for use means that all the support parts 4 can be normally supported on the support surface, thereby providing support for the bed body 3 and maintaining the stable use of the bed body 3; if the support part 4 cannot be normally supported on the support surface, it will not meet the requirements of safe support, cannot meet the EU testing standards, and there will be safety hazards. At this time, the bed body 3 cannot be used as a play bed.

[0212] Example 4

[0213] See also Figure 29 to Figure 52 This embodiment also discloses a multifunctional baby bed. The multifunctional baby bed of this embodiment is further optimized on the basis of Embodiment 1, 2 or 3: due to the different structure of the bottom frame 31, after the bed body 3 is removed from the base 1, it can be used as a baby bed or as a playbed, which further increases the function of the product, further improves its cost performance, and meets more usage needs of consumers.

[0214] It should be noted that, similar to Embodiment 1, 2 or 3, the multifunctional baby bed of this embodiment also includes a base 1, a connecting part 2, a bed body 3, a supporting part 4, a first linkage mechanism 5 and a second linkage mechanism 6. The bed body 3 also includes a base frame 31, a bed frame 32, a lifting assembly 33, and a software component 34. The first and second layers of the soft component 34 are also provided with a locking part 35. When the bed body 3 is in a first depth state and the locking part 35 is locked with the bed body 3, the first linkage mechanism 5 allows the base frame 31 to be locked with the connecting part 2. When the locking part 35 is unlocked with the bed body 3, the first linkage mechanism 5 prevents the base frame 31 from being locked with the connecting part 2. When the base frame 31 is locked with the connecting part 2, the first linkage mechanism 5 prevents the locking part 35 from being unlocked with the bed body 3, so that the first layer 341 and the second layer 342 remain locked. The multifunctional baby bed of this embodiment, when the bed body 3 is installed on the base 1 and used in the first depth state, can also realize the storage and locking of the software 34 to avoid forming a cloth bag, and cannot be unlocked manually, thereby preventing the occurrence of safety accidents and passing the EU test standards, solving the same technical problems as those shown in Example 1, and achieving the same technical effects as those shown in Example 1. For specific principles and related descriptions, please refer to the relevant solution content in Example 1, and will not be repeated here.

[0215] See also Figures 33 to 37In particular, in the present embodiment, the base frame 31 includes a movable frame 311 and a fixed frame 312, the soft part is connected between the movable frame 311 and the bed frame 32, the movable frame 311 can be raised and lowered with the bed frame 32, the fixed frame 312 and the lifting assembly 33 are relatively fixedly arranged, the movable frame 311 can move closer to or away from the fixed frame 312, the bed frame 32 has a first preset height and a second preset height, the first preset height is the initial height of the bed frame 32 when the bed body 3 is in the first depth state, and the second preset height is the height of the bed frame 32 after rising when the bed body 3 is in the second depth state; the support part 4 is connected to the bed body 3, when the base frame 31 is unlocked and separated from the connecting part 2, and the bed frame 32 is at the second preset height, the second linkage mechanism 6 can allow the support part 4 to be supported on the support surface for use, and at the same time the second linkage mechanism 6 prevents the contraction of the lifting assembly 33 so that the bed frame 32 remains at the second preset height.

[0216] In the above scheme, the movable frame 311 can be raised and lowered along with the bed frame 32, and by utilizing the function of the second linkage mechanism 6, when the bottom frame 31 is unlocked and separated from the connecting portion 2 so as to remove the bed body 3 from the base 1, the height of the bed frame 32 must be adjusted to the second preset height before the support portion 4 can be supported on the support surface (such as the ground, etc.), and the second linkage mechanism 6 is also utilized to prevent the contraction of the lifting assembly 33 so that the bed frame 32 remains at the second preset height. During the rising process of the bed frame 32, when the locking portion 35 keeps locking the first layer 341 and the second layer 342, the locking portion 35 is locked. 42, the movable frame 311 will rise with the bed frame 32 until the bed frame 32 is at the second preset height, so that the bed body 3 is in the first depth state, so that the bed body 3 is in the baby bed position and can be used as a baby bed; because the bed frame 32 remains at the second preset height, when the first layer 341 and the second layer 342 are unlocked by the lock part 35, the movable frame 311 can descend under the action of gravity so that the first layer 341 and the second layer 342 are separated from each other, so that the bed body 3 is in the second depth state, so that the bed body 3 is in the play bed position and can be used as a play bed.

[0217] In this way, the above-mentioned multifunctional baby bed can be used as a baby bed or as a playbed after the bed body 3 is removed from the base 1, and the height of the bed frame 32 cannot be adjusted when the support part 4 is supported on the support surface for use, thereby overcoming the shortcomings of manually adjusting the height of the bed frame 32 to adjust the bed body 3 from the second depth state to the first depth state or the depth size of the bed body 3 that does not meet the EU safety test requirements when the support part 4 is supported on the support surface for use as a playbed. As a result, the bed body 3 meets the EU safety test standards when used as a playbed without safety hazards, that is, further increasing the function of the product, improving its cost performance, and meeting the EU safety test standards to meet more consumer usage needs.

[0218] See also Figures 48 to 52It can be understood that the second linkage mechanism 6 and the support part 4 of this embodiment can adopt the specific scheme of the second linkage mechanism 6 and the support part 4 in Embodiment 1, 2 or 3, so as to meet the above-mentioned purpose and function. Preferably, in order to facilitate subsequent improvements, this embodiment specifically adopts the specific scheme of the second linkage mechanism 6, the support part 4 and the lifting assembly 33 disclosed in Embodiment 1, and reference can be made to the relevant description in Embodiment 1.

[0219] See also Figures 33 to 37 Since the movable frame 311 can be raised and lowered with the bed frame 32, preferably, the bed body 3 further includes a guide rail 38, which is fixedly arranged relative to the lifting assembly 33. Specifically, the guide rail 38 is arranged on the second connecting rod 332, and the extension direction of the guide rail 38 is parallel to the lifting direction of the bed frame 32. The movable frame 311 is slidably arranged on the guide rail 38. In this way, the guide rail 38 is used to guide the lifting and lowering of the movable frame 311, so as to avoid or reduce the shaking of the movable frame 311. Specifically, a slide seat 3111 is arranged on the movable frame 311, and the slide seat 3111 cooperates with the guide rail 38.

[0220] See also Figures 33 to 37 In addition, a depth limiting rod 37 for resisting or separating from the movable frame 311 is provided at the upper end of the bed frame 32 or the lifting assembly 33. When the bed body 3 is in the first depth state, the depth limiting rod 37 resists the movable frame 311. Preferably, the upper end of the depth limiting rod 37 is connected to the upper end of the first connecting rod 331. In this way, the depth limiting rod 37 is used to control the minimum depth of the bed body 3, so that the depth dimension of the bed body 3 is not allowed to be adjusted to a depth dimension less than the first depth state, so that the bed body 3 meets the EU safety test standards when used as a baby bed without safety hazards; and based on the existence of the guide rail 38, there may be friction when the movable frame 311 slides on the guide rail 38, which makes it difficult for the movable frame 311 to smoothly descend under the action of gravity. At this time, the resisting effect of the depth limiting rod 37 can also be used. When the bed body 3 is in the first depth state and when the bed frame 32 is driven to descend, the bed frame 32 can be pushed down together with the movable frame 311 by the depth limiting rod 37, which is more convenient to operate.

[0221] See also Figures 45 to 47 In the present embodiment, in order to reduce the volume of the support part 4 when it is stored, and to provide a wider supporting torque when the playbed is used, so as to improve safety, preferably, the support part 4 includes a rotating body 44, a supporting leg 45, and a locking and unlocking mechanism 46. The rotating body 44 is pivotally connected to the bed body 3, and the supporting leg 45 is slidably arranged on the rotating body 44. The locking and unlocking mechanism 46 is arranged between the rotating body 44 and the bed body 3 to lock the rotating body 44 in a folded state. When the supporting leg 45 slides outward to a preset length, the supporting leg 45 triggers the locking and unlocking mechanism 46, so that the locking and unlocking mechanism 46 releases the lock on the rotating body 44, thereby allowing the rotating body 44 to rotate to an unfolded state with the supporting leg 45.

[0222] In this way, using the above-mentioned support part 4, when you want to support the support part 4 on the support surface for use, you must first slide the support legs 45 outward to a preset length before unlocking it, allowing the rotating body 44 to rotate with the support legs 45 to the unfolded state, ensuring that the support legs 45 are extended before use. When the bed body 3 is installed on the base 1 when the rocking bed is used or packaged for export, the support legs 45 can slide inward and retract, and the locking and unlocking mechanism 46 can be used to lock the rotating body 44 in the folded state, so that the support part 4 occupies a small volume as a whole and is not easy to loosen.

[0223] See also Figures 45 to 47 Specifically, the locking and unlocking mechanism 46 includes a seventh locking block 461 and a fourteenth reset piece 462. The seventh locking block 461 is movably arranged on the rotating body 44, and the fourteenth reset piece 462 is arranged between the seventh locking block 461 and the rotating body 44. A first locking hole 39 plugged and matched with the seventh locking block 461 is arranged on the bed body 3. A shift block 451 is arranged on the supporting foot 45. When the supporting foot 45 slides outward to a preset length, the shift block 451 pushes the seventh locking block 461 to move, so that the seventh locking block 461 disengages from the first locking hole 39, thereby releasing the lock of the rotating body 44. In this way, the locking or unlocking of the rotating body 44 is achieved, wherein the supporting foot 45 pushes the seventh locking block 461 to move only after sliding a certain stroke, thereby ensuring that the supporting foot 45 has a larger telescopic length and the locking or unlocking stroke of the seventh locking block 461 is smaller. It is understandable that the cooperation between the support leg 45 and the seventh locking block 461 may also adopt other known structures, such as providing a long groove on the support leg 45 and providing a protrusion on the seventh locking block 461 that can slide relatively and abut against each other in the long groove.

[0224] Of course, the support foot 45 may also be provided with a marble, and the rotating body 44 may be provided with two holes that cooperate with the marble, so that the support foot 45 can be positioned at the retracted position or the extended position.

[0225] See also Figures 38 to 44 In this embodiment, a solution of the first linkage mechanism 5 different from that of the first embodiment is proposed, which can be better applied to the movable frame 311. Specifically, the first linkage mechanism 5 includes a first locking and unlocking component 81, a first limiting component 53, and a second limiting component 55.

[0226] In this embodiment, the first locking and unlocking component 81 is arranged between the movable frame 311 and the lifting component 33. The first locking and unlocking component 81 is used to lock or unlock the lock part 35. When the base frame 31 is unlocked and separated from the connecting part 2, and the bed frame 32 rises to a second preset height, the first locking and unlocking component 81 releases the lock part 35, thereby allowing the lock part 35 to be unlocked from the bed body 3.

[0227] Preferably, the first locking and unlocking assembly 81 includes a first driving member 811, a first movable member 812 for limiting the locking portion 35, and an eleventh reset member 813. The first driving member 811 is arranged on the lifting assembly 33, the first movable member 812 is movably arranged on the movable frame 311, and the eleventh reset member 813 is arranged between the first movable member 812 and the movable frame 311. When the bed frame 32 rises with the movable frame 311 until the bed frame 32 is at a second preset height, the first driving member 811 drives the first movable member 812 to move relative to the movable frame 311 and change its position, so that the first movable member 812 is separated from the locking portion 35 and the restriction on the locking portion 35 is released, thereby allowing the locking portion 35 to be unlocked from the bed body 3.

[0228] Specifically, the first movable member 812 is slidably arranged on the movable frame 311, the lock portion 35 is a zipper structure, and the lock portion 35 includes two chain belts 351, a pull head 352, and a clamping member 353. The two chain belts 351 are respectively connected to the first layer 341 and the second layer 342, the pull head 352 cooperates with the chain belts 351, and the clamping member 353 is connected to the pull head 352. The clamping member 353 is used for detachable insertion with the movable frame 311, and the clamping member 353 is provided with a The first movable member 812 is provided with an escape groove 814 to match the first locking groove 3531. The first movable member 812 slides and fits into the first locking groove 3531 under the reset action of the eleventh reset member 813 to restrict the clamping member 353 on the movable frame 311. The first movable member 812 slides and changes its position under the driving action of the first driving member 811 so that the escape groove 814 is aligned with the first locking groove 3531, so that the first movable member 812 releases the restriction on the clamping member 353. The first driving member 811 can be specifically fixedly connected to the upper end of the second connecting rod 332, and the first movable member 812 and the eleventh reset member 813 can be specifically arranged on the slide seat 3111 of the movable frame 311.

[0229] Thus, in the above scheme, when the connecting part 2 is unlocked from the base frame 31 and the bed frame 32 is not raised, the first movable member 812 keeps restricting the snap-in member 353 on the movable frame 311, and when the bed frame 32 is raised to a second preset height so that the supporting part 4 can be supported on the supporting surface for use, the first movable member 812 releases the restriction on the snap-in member 353 under the driving action of the first driving member 811. At this time, the snap-in member 353 can be pulled out to complete the unlocking, thereby allowing the bed body 3 to switch from the first depth state to the second depth state.

[0230] See also Figures 37 to 44In this embodiment, the first limiting component 53 is arranged on the bed body 3 and can be used to block the connecting part 2. The first limiting component 53 includes a first blocking state and a first avoidance state. When the bed frame 32 is at a first preset height, the first limiting component 53 is in the first avoidance state. At this time, the first limiting component 53 releases the restriction on the connecting part 2, thereby allowing the connecting part 2 to be locked with the base frame 31; when the base frame 31 is unlocked and separated from the connecting part 2, and the bed frame 32 rises with the movable frame 311 away from the first preset height, the first limiting component 53 switches from the first avoidance state to the first blocking state. At this time, the first limiting component 53 prevents the connecting part 2 from being locked with the base frame 31.

[0231] Based on the split structure of the bottom frame 31 (the bottom frame 31 includes a movable frame 311 and a fixed frame 312), preferably, the bed body 3 also includes a mounting seat 36 for locking or unlocking with the connecting portion 2, the mounting seat 36 is arranged on one of the fixed frame 312 and the movable frame 311, the first limiting component 53 is arranged on the mounting seat 36, and a trigger 54 for cooperating with the first limiting component 53 is arranged on the other of the fixed frame 312 and the movable frame 311. When the movable frame 311 moves toward the fixed frame 312, the trigger 54 drives the first limiting component 53 to switch from the first blocking state to the first avoiding state. Fig.34 As shown in FIG. 1 , as a specific example, the mounting seat 36 is disposed on the movable frame 311, and the trigger member 54 is disposed on the fixed frame 312. When the movable frame 311 descends, the movable frame 311 brings the mounting seat 36 and the first limiting component 53 to press downward toward the trigger member 54, so that the trigger member 54 triggers the first limiting component 53 to complete the state switching; Fig.35 As shown, as another specific example, the mounting seat 36 is set on the fixed frame 312, and the trigger member 54 is set on the movable frame 311. When the movable frame 311 descends, the movable frame 311 carries the trigger member 54 and presses down toward the mounting seat 36 and the first limiting component 53, so that the trigger member 54 triggers the first limiting component 53 to complete the state switching.

[0232] The base frame 31 is constructed by combining a fixed frame 312 with a movable frame 311, which not only facilitates locking by using the first limiting component 53 and the trigger component 54, but also the fixed frame 312 is connected between the two lifting components 33 to play a fastening role, thereby improving the stability of the bed 3.

[0233] See also Fig.41 and Fig.43Specifically, the mounting seat 36 is provided with a first mounting groove 362 for plugging the connecting part 2, the first limiting component 53 includes a fourth movable member 531 and a tenth reset member 532, the fourth movable member 531 is movably arranged on the mounting seat 36 and the fourth movable member 531 can extend into the first mounting groove 362 to form a block to the connecting part 2, and the tenth reset member 532 is arranged between the fourth movable member 531 and the mounting seat 36; when the movable frame 311 moves closer to the fixed frame 312, the trigger member 54 drives the fourth movable member 531 to move and give way to release the blockage of the connecting part 2. As a specific example, the fourth movable member 531 is slidably arranged in the mounting seat 36 up and down, and the trigger member 54 can push the fourth movable member 531 to slide out of the first mounting groove 362, so that the first limiting component 53 is switched from the first blocking state to the first avoidance state.

[0234] In particular, the trigger member 54 is also provided with a second locking groove 541 for cooperating with the connecting portion 2; when the bed body 3 is in the first depth state and the connecting portion 2 is locked with the mounting seat 36, the connecting portion 2 is inserted into the second locking groove 541 to lock the trigger member 54 on the mounting seat 36, so that the movable frame 311 and the fixed frame 312 are kept close. In this way, the first linkage mechanism 5 prevents the movable frame 311 from rising when the base frame 31 is locked with the connecting portion 2, so that the bed frame 32 cannot deviate from the first preset height, so that the first locking and unlocking assembly 81 keeps locking the locking portion 35, thereby preventing the locking portion 35 from being unlocked from the bed body 3.

[0235] See also Figures 38 to 42 In this embodiment, the second limiting component 55 is used to cooperate with the lock part 35. The second limiting component 55 is arranged between the movable frame 311 and the fixed frame 312 or between the movable frame 311 and the lifting component 33. The second limiting component 55 is used to prevent or allow the movable frame 311 to move closer to the fixed frame 312. The second limiting component 55 includes a second blocking state and a second avoidance state; when the lock part 35 is locked with the bed body 3, the lock part 35 drives the second limiting component 55 to switch from the second blocking state to the second avoidance state, so that the second limiting component 55 allows the movable frame 311 to move closer to the fixed frame 312; when the lock part 35 is unlocked from the bed body 3, the lock part 35 is separated from the second limiting component 55, and the second limiting component 55 can be reset to the second blocking state at this time, so that the second limiting component 55 prevents the movable frame 311 from moving closer to the fixed frame 312.

[0236] Due to the existence of the first locking and unlocking component 81 and the first limiting component 53, the second limiting component 55 may not have the function of preventing the locking portion 35 from being unlocked from the bed body 3, but may have the function of preventing or allowing the movable frame 311 from moving closer to the fixed frame 312. That is, in the above scheme, when the locking portion 35 is locked with the bed body 3, the second limiting component 55 allows the movable frame 311 to move closer to the fixed frame 312, so that the trigger member 54 can trigger the first limiting component 53, so that the first limiting component 53 allows the connecting portion 2 to be locked with the bed body 3; and when the locking portion 35 is unlocked from the bed body 3, the second limiting component 55 prevents the movable frame 311 from moving closer to the fixed frame 312, so that the trigger member 54 cannot trigger the first limiting component 53, so that the first limiting component 53 prevents the connecting portion 2 from being locked with the bed body 3.

[0237] Specifically, the second limiting component 55 includes a third movable member 551, a ninth reset member 552, and a second stop block 553. The third movable member 551 is movably arranged on the movable frame 311, the second stop block 553 is arranged on the fixed frame 312 or the lifting component 33, and the ninth reset member 552 is arranged between the third movable member 551 and the movable frame 311; when the snap-in member 353 is plugged into the movable frame 311, the snap-in member 353 pushes the third movable member 551 to move out of the way, so that the third movable member 551 is separated from the second stop block 553 to allow the movable frame 311 to move closer to the fixed frame 312; when the snap-in member 353 is separated from the movable frame 311, the ninth reset member 552 drives the third movable member 551 to reset, so that the third movable member 551 can be against the second stop block 553 to prevent the movable frame 311 from moving closer to the fixed frame 312. Among them, the third movable member 551 and the ninth reset member 552 can be specifically arranged on the slide 3111 of the movable frame 311, the third movable member 551 can be horizontally slid on the slide 3111, of course, the third movable member 551 can also be horizontally rotatably connected to the slide 3111, and the second stop block 553 can be specifically fixedly connected to the lower end of the second connecting rod 332.

[0238] Thus, in the above scheme, when the lock portion 35 is unlocked from the bed body 3, that is, the snap-in component 353 is not plugged into the movable frame 311, the third movable component 551 will be located above the second stop block 553 to form a resistance, thereby preventing the movable frame 311 from continuing to descend, so that the movable frame 311 cannot be brought close to the fixed frame 312, thereby making the first limiting component 53 in the first blocking state; when the lock portion 35 is unlocked from the bed body 3, that is, the snap-in component 353 is plugged into the movable frame 311, the snap-in component 353 drives the third movable component 551, so that the third movable component 551 leaves the top of the second stop block 553, thereby forming an avoidance, thereby allowing the movable frame 311 to continue to descend, so that the movable frame 311 is brought close to the fixed frame 312, thereby making the first limiting component 53 in the first avoidance state.

[0239] It should be noted that, based on the fact that the first linkage mechanism 5 has the function of allowing or preventing the lock part 35 from being unlocked from the bed body 3, when the first linkage mechanism 5 adopts other structures to allow the lock part 35 to be unlocked from the bed body 3, the first locking and unlocking component 81 can also be used as a second solution independent of the first linkage mechanism 5 to lock or unlock the lock part 35, so that the lock part 35 can only be released when the bed frame 32 rises to a second preset height, thereby allowing the lock part 35 to be unlocked from the bed body 3, thereby further improving safety.

[0240] Example 5

[0241] See also Figures 53 to 59 This embodiment also discloses a multifunctional baby bed. The multifunctional baby bed of this embodiment differs from that of Embodiment 4 in that the first unlocking and locking component is cancelled and the function of the second limiting component 55 is added.

[0242] Similar to Example 4, the first linkage mechanism 5 of this embodiment also includes a first limiting component 53 and a second limiting component 55, while the first unlocking and locking component is cancelled, wherein the first limiting component 53 of this embodiment is the same as the first limiting component 53 of Example 4, and the second limiting component 55 of this embodiment is further optimized on the basis of the first limiting component 53 of Example 4.

[0243] Similar to Example 4, the second limiting component 55 is arranged between the movable frame 311 and the fixed frame 312 or between the movable frame 311 and the lifting component 33. The second limiting component 55 is used to prevent or allow the movable frame 311 to move closer to the fixed frame 312. The second limiting component 55 includes a second blocking state and a second avoidance state; when the lock part 35 is locked with the bed body 3, the lock part 35 drives the second limiting component 55 to switch from the second blocking state to the second avoidance state, so that the second limiting component 55 allows the movable frame 311 to move closer to the fixed frame 312; when the lock part 35 is unlocked from the bed body 3, the lock part 35 is disengaged from the second limiting component 55, and the second limiting component 55 can be reset to the second blocking state at this time, so that the second limiting component 55 prevents the movable frame 311 from moving closer to the fixed frame 312; further improved, when the lock part 35 is locked with the bed body 3 and the movable frame 311 moves closer to the fixed frame 312, the second limiting component 55 can also prevent the lock part 35 from being unlocked from the bed body 3. In this way, the second limiting component 55 has the function of preventing the locking portion 35 from being unlocked from the bed body 3 .

[0244] See also Figure 56 to Figure 59Specifically, what is different from Example 4 is that the second stopper 553 in the second limiting component 55 can cooperate with the first locking groove 3531 of the clamping member 353; when the clamping member 353 is inserted into the movable frame 311, the clamping member 353 pushes the third movable member 551 to move and make way, so that the third movable member 551 is separated from the second stopper 553 to allow the movable frame 311 to move closer to the fixed frame 312, and after the movable frame 311 moves closer to the fixed frame 312, the second stopper 553 is inserted into the first locking groove 3531 to lock the clamping member 353, thereby preventing the clamping member 353 from detaching from the movable frame 311; when the clamping member 353 detaches from the movable frame 311, the ninth resetting member 552 drives the third movable member 551 to reset, so that the third movable member 551 can be against the second stopper 553 to prevent the movable frame 311 from moving closer to the fixed frame 312.

[0245] Example 6

[0246] See also Figures 60 to 67 This embodiment also discloses a multifunctional baby bed. The multifunctional baby bed of this embodiment is different from that of Embodiment 4 in that the second linkage mechanism 6 is cancelled and a third linkage mechanism 8 is added.

[0247] In the present embodiment, a third linkage mechanism 8 is also included. The third linkage mechanism 8 is arranged on the bed body 3 and is used to cooperate with the lock part 35. The third linkage mechanism 8 includes a first state, a second state, and a third state. When the base frame 31 is unlocked and separated from the connecting part 2, the bed frame 32 is located at the first preset height and the lock part 35 is locked with the bed body 3, the third linkage mechanism 8 is in the first state. When the bed frame 32 rises to the second preset height, the third linkage mechanism 8 switches from the first state to the second state so that the third linkage mechanism 8 releases the lock part 35, thereby allowing the lock part 35 to be unlocked from the bed body 3. After the lock part 35 is unlocked from the bed body 3, the lock part 35 releases the restriction on the third linkage mechanism 8, so that the third linkage mechanism 8 switches from the second state to the third state, so that the third linkage mechanism 8 prevents the lifting assembly 33 from shrinking, thereby keeping the bed frame 32 at the second preset height.

[0248] In the above scheme, the movable frame 311 can be raised and lowered with the bed frame 32. By utilizing the action of the third linkage mechanism 8, when the base frame 31 is unlocked and separated from the connecting portion 2 to remove the bed body 3 from the base 1, the height of the bed frame 32 must be adjusted to the second preset height before the third linkage mechanism 8 can release the lock portion 35, thereby allowing the lock portion 35 to be unlocked from the bed body 3. After the lock portion 35 is unlocked from the bed body 3, the third linkage mechanism 8 will prevent the contraction of the lifting assembly 33 so that the bed frame 32 remains at the second preset height. The movable frame 311 can descend under the action of gravity so that the first layer 341 and the second layer 342 are moved away from each other, so that the bed body 3 is in a second depth state, so that the bed body 3 is in a game bed position and can be used as a game bed.

[0249] In this way, the above-mentioned multifunctional baby bed can be used as a baby bed or as a playbed after the bed body 3 is removed from the base 1, and the height of the bed frame 32 cannot be adjusted when used as a playbed, thereby overcoming the disadvantages of manually adjusting the height of the bed frame 32 to adjust the bed body 3 from the second depth state to the first depth state or the depth size of the bed body 3 not meeting the EU safety test requirements when used as a playbed. As a result, the bed body 3 meets the EU safety test standards when used as a playbed without any safety hazards, that is, the function of the product is further increased, its cost-effectiveness is improved, and it can meet the EU safety test standards and meet more consumer usage needs.

[0250] In addition, in order to adjust the height of the crib when it is in use after the bed body 3 is removed from the base 1, preferably, the lifting assembly 33 has multiple adjustable height gears, wherein the two height gears correspond to the first preset height and the second preset height, respectively. When the bed body 3 is maintained in the first depth state and the base frame 31 is unlocked and separated from the connecting part 2, the bed frame 32 can be lifted and lowered with the movable frame 311 to at least two other heights beyond the second preset height and keep the locking part 35 locked with the bed body 3, that is, when the crib is in use, its height is adjustable to adapt to different application scenarios, thereby meeting more usage needs of consumers.

[0251] It should be noted that the lifting component 33 with multiple adjustable height levels is a prior art, and the utility model does not lie in the specific structure of the lifting component 33. Any lifting component 33 that can achieve adjustable height levels can be used.

[0252] refer to Figures 63 to 67 , combined with Example 4 Figures 48 to 52For ease of understanding, a specific example of the lifting assembly 33 that can be used is as follows: the lifting assembly 33 includes a first connecting rod 331, a second connecting rod 332, and a locking pin structure 333. The first connecting rod 331 is slidably arranged on the second connecting rod 332, the bed frame 32 is connected to the upper end of the first connecting rod 331, the movable frame 311 is slidably arranged on the second connecting rod 332, the fixed frame 312 is fixedly connected to the lower end of the second connecting rod 332, and the locking pin structure 333 includes a sliding switch 3331, a cable 3332, and a lifting lock block. 3333, a lifting slider 3334 and a spring 3335, a sliding switch 3331 is slidably arranged at the upper end of the first connecting rod 331, the sliding switch 3331 is connected to one end of the cable 3332, a lifting lock block 3333 is horizontally slidably arranged at the lower end of the first connecting rod 331, a plurality of third lock holes arranged from top to bottom are arranged on the side wall of the second connecting rod 332, different third lock holes correspond to different height gears, the lifting lock block 3333 can be plugged and matched with the third lock holes, and the lifting slider 3333 is vertically slidably arranged at the lower end of the first connecting rod 331. A connecting rod 331 is provided with a protrusion on one side of the lifting lock block 3333, and an inclined groove is provided on the lifting slider 3334. The protrusion and the inclined groove match each other. The spring 3335 is provided between the first connecting rod 331 and the lifting slider 3334. The lifting slider 3334 is connected to the other end of the cable 3332. When the sliding switch 3331 is pressed upward, the sliding switch 3331 drives the lifting slider 3334 to slide upward through the cable 3332, and the lifting slider 3334 compresses the spring 3335, and the lifting slider 3334 is pressed upward. Under the cooperation of the protrusion and the inclined groove, 334 drives the lifting lock block 3333 to slide, so that the lifting lock block 3333 disengages from the third lock hole to complete unlocking. At this time, the first connecting rod 331 can be lifted and lowered relative to the second connecting rod 332. When the sliding switch 3331 is released, the lifting slider 3334 slides downward and resets under the elastic force of the spring 3335, and the lifting slider 3334 drives the lifting lock block 3333 to slide in the opposite direction under the cooperation of the protrusion and the inclined groove, so that the lifting lock block 3333 is inserted into the third lock hole to complete locking.

[0253] In this embodiment, the third linkage mechanism 8 includes a first locking and unlocking component 81 and a second locking and unlocking component 82, wherein the first locking and unlocking component 81 of this embodiment is the same as the first locking and unlocking component 81 of embodiment 4. In this embodiment, although the first locking and unlocking component 81 is attributed to the third linkage mechanism 8, and in embodiment 4, the first locking and unlocking component 81 is attributed to the second linkage mechanism 6, this is only based on the difference in description methods, and the specific scheme of the first locking and unlocking component 81 and the effect achieved are the same. When it is determined that there is a need, the first locking and unlocking component 81 can also be re-attributed to the second linkage mechanism 6.

[0254] Similar to the fourth embodiment, the first locking and unlocking assembly 81 is disposed between the movable frame 311 and the lifting assembly 33. The first locking and unlocking assembly 81 is used to lock or unlock the lock portion 35. When the base frame 31 is unlocked and separated from the connecting portion 2, and the bed frame 32 rises to the second preset height, the first locking and unlocking assembly 81 releases the lock of the lock portion 35, thereby allowing the lock portion 35 to be unlocked from the bed body 3. Since the first locking and unlocking assembly 81 of this embodiment is the same as the first locking and unlocking assembly 81 of the fourth embodiment, the first locking and unlocking assembly 81 will not be described again, and the relevant description of the first locking and unlocking assembly 81 in the fourth embodiment may be referred to.

[0255] In this embodiment, the second locking and unlocking component 82 is arranged between the movable frame 311 and the lifting component 33, and the second locking and unlocking component 82 is used to lock or unlock the lifting component 33, wherein when the lock part 35 is locked with the bed body 3, the lock part 35 drives the second locking and unlocking component 82 so that the second locking and unlocking component 82 releases the lock of the lifting component 33, and when the lock part 35 is unlocked with the bed body 3, the second locking and unlocking component 82 is reset to lock the lifting component 33. For ease of understanding, as a specific example, the second locking and unlocking component 82 can lock or unlock the aforementioned sliding switch 3331, that is, when the locking part 35 is locked with the bed body 3, the second locking and unlocking component 82 unlocks the sliding switch 3331, and the sliding switch 3331 can slide freely, so that the sliding switch 3331 can be pressed as needed to unlock the first connecting rod 331 relative to the second connecting rod 332, so that the first connecting rod 331 can be raised and lowered relative to the second connecting rod 332 to adjust different height gears; and when the locking part 35 is unlocked with the bed body 3, the second locking and unlocking component 82 locks the sliding switch 3331, so that the sliding switch 3331 cannot slide, so that the first connecting rod 331 cannot be unlocked relative to the second connecting rod 332, thereby keeping the bed frame 32 at the second preset height.

[0256] Preferably, the second locking and unlocking assembly 82 includes a second trigger part 821, a sixth locking part 822, and a sixth transmission member 823. The second trigger part 821 is arranged on the movable frame 311 and is used to cooperate with the lock part 35. The sixth locking part 822 is arranged on the lifting assembly 33 and is used to lock or unlock the lifting assembly 33. The sixth transmission member 823 is connected between the second trigger part 821 and the sixth locking part 822; when the lock part 35 is unlocked from the bed body 3, the lock part 35 is separated from the second trigger part 821 to release the restriction on the second trigger part 821. The second trigger part 821 moves and resets relative to the movable frame 311 and releases the driving action of the sixth locking part 822 through the sixth transmission member 823, so that the sixth locking part 822 locks the lifting assembly 33 after being reset, so that the bed frame 32 remains at the second preset height.

[0257] See also Figures 63 to 67Specifically, the second triggering part 821 includes a second movable member 8211, a twelfth resetting member 8212, and a second slider 8213. The second movable member 8211 is movably arranged on the movable frame 311, the twelfth resetting member 8212 is arranged between the second movable member 8211 and the movable frame 311, the second slider 8213 is slidably arranged at the lower end of the depth limiting rod 37, and the second slider 8213 can be raised and lowered with the depth limiting rod 37, and the second slider 8213 is connected to the sixth transmission member 823; wherein, the locking part 35 can push the second movable member 8211 to move toward the second slider 8213 so that the second movable member 8211 pushes the second slider 8213 to slide, so that the second slider 8213 drives the sixth locking part 822 through the sixth transmission member 823, or the twelfth resetting member 8212 can drive the second movable member 8211 to move and reset.

[0258] Specifically, the sixth locking portion 822 includes a sixth locking block 8221 and a thirteenth reset member 8222 for locking or unlocking the locking pin structure 333. The sixth locking block 8221 is movably arranged on the first connecting rod 331, and the thirteenth reset member 8222 is arranged between the sixth locking block 8221 and the first connecting rod 331. The sixth locking block 8221 is connected to the sixth transmission member 823; when the locking portion 35 pushes the second movable member 8211 to move, the second movable member 8211 drives the sixth locking block 8221 to move through the second slider 8213 and the sixth transmission member 823, so that the sixth locking block 8221 releases the lock on the locking pin structure 333; when the second movable member 8211 moves and resets, the second movable member 8211 releases the driving action on the sixth locking block 8221, so that the sixth locking block 8221 resets and locks the locking pin structure 333, thereby keeping the bed frame 32 at the second preset height.

[0259] As a specific example, the second movable member 8211 is horizontally slidably arranged on the slide seat 3111 of the movable frame 311, the second movable member 8211 is provided with a first abutting inclined surface, the twelfth reset member 8212 is a spring arranged between the second movable member 8211 and the slide seat 3111, the second slider 8213 is slidably arranged up and down on the lower end of the depth limiting rod 37, the second slider 8213 is provided with a second abutting inclined surface matching the first abutting inclined surface, the sixth transmission member 823 is preferably a cable, and the upper end of the second slider 8213 is connected to the first slider 8213. The lower ends of the sixth transmission member 823 are connected, the depth limiting rod 37 is provided with a pin for limiting the sliding stroke of the second slider 8213 and limiting the axial rotation of the second slider 8213, the sixth locking block 8221 is horizontally slidably arranged on the upper end of the first connecting rod 331, the position of the sixth locking block 8221 corresponds to the position of the sliding switch 3331, the thirteenth reset member 8222 is a spring between the sixth locking block 8221 and the first connecting rod 331, and the sixth locking block 8221 is connected to the upper end of the sixth transmission member 823; when the lock portion 3 When the locking part 35 is unlocked from the bed body 3 (specifically, when the clamping part 353 is pulled out of the slide seat 3111 of the movable frame 311), the twelfth reset part 8212 can elastically drive the second movable part 8211 to slide away from the sixth locking block 8221 and reset, and the thirteenth reset part 8222 can elastically drive the sixth locking block 8221 to slide toward the sliding switch 3331 and reset to lock the sliding switch 3331. When the sixth locking block 8221 is reset, the second sliding block 8213 is driven to slide upward through the sixth transmission member 823. ... When locked (specifically, when the clamping member 353 is inserted into the sliding seat 3111 of the movable frame 311), the locking portion 35 pushes the second movable member 8211 to slide toward the second slider 8213 and compresses the twelfth reset member 8212. Under the cooperation of the first abutting inclined surface and the second abutting inclined surface, the second movable member 8211 drives the second slider 8213 to slide downward, and the second slider 8213 pulls the sixth locking block 8221 away from the sliding switch 3331 through the sixth transmission member 823, thereby unlocking the sliding switch 3331.

At this time, the first limiting component 53 releases the restriction on the connecting part 2 to allow the connecting part 2 to be locked with the base frame 31; when the base frame 31 is unlocked and separated from the connecting part 2, and the bed frame 32 rises with the movable frame 311 away from the first preset height, the first limiting component 53 switches from the first avoidance state to the first blocking state. At this time, the first limiting component 53 prevents the connecting part 2 from being locked with the base frame 31.
