[0053] In order to facilitate understanding of the present application, the present application will be described in more detail below with reference to the accompanying drawings. However, the present application can be realized in many different forms and is not limited to the embodiments described herein. On the other hand, the purpose of providing the embodiments is to make the contents disclosed in the present application more clear and complete.

[0054] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the art to which this application belongs. In this application, the terms used in the specification of this application are merely intended to describe certain embodiments and are not intended to limit this application. As used herein, the term "and / or" includes any and all combinations of one or more of the associated listed items.

[0055] 1, 3, 5, and 6, a bed frame structure 100 according to an embodiment includes a bottom assembly 1 and two support assemblies 2. The bottoms of the two support assemblies 2 are fixed to the bottom assembly 1, and the two support assemblies 2 are arranged above the bottom assembly 1 at intervals. Each of the two support assemblies 2 is foldable. Specifically, the support assembly 2 has a pivot connection point 21 that allows both ends of the support assembly to rotate so as to be folded. The bed frame structure 100 also includes two armrests 3. The two armrests 3 are arranged between the two support assemblies 2 at intervals. Both ends of the two armrests 3 are respectively arranged on the two support assemblies 2 so as to be movable up and down. The bottom assembly 1, the support assembly 2, and the two armrests 3 together form a rest space 4. When the two armrests 3 slide downward to a position below the pivot connection point 21, the two support assemblies 2 can be folded inward respectively, thereby folding the bed frame structure 100. In this way, the operation is simple and convenient compared to other methods.

[0056] 1 and 3, the support assembly 2 includes two support rods 22 and a connecting rod 23. The pivot connection point 21 is disposed at a position between both ends of each support rod 22. The connecting rod 23 is fixedly connected between the two support rods 22. In this embodiment, one end of each of the two support rods 22 is fixedly connected to the connecting rod 23, and the other end of each of the two support rods 22 is fixed to the bottom assembly 1. The two armrests 3 are respectively disposed on the two support rods 22 so as to be movable up and down. Specifically, each support rod 22 includes a first rod portion 221 and a second rod portion 222. The first rod portion 221 and the second rod portion 222 are pivotally connected by the pivot connection point 21. The bottom of the second rod portion 222 is fixed to the bottom assembly 1.

[0057] Referring also to FIG. 4, the support rod 22 further includes a locking member 223. In this embodiment, one end of the locking member 223 is movably disposed in the first rod portion 221, and the other end of the locking member 223 is locked to the second rod portion 222. The locking member 223 is moved to disengage from the second rod portion 222, so that the first rod portion 221 can rotate to a folded state relative to the second rod portion 222. A sliding groove 221a is formed in the first rod portion 221, and a locking groove 222a is formed in the upper portion of the second rod portion 222. The locking member 223 includes a sliding portion 223a and a locking portion 223b connected to the sliding portion 223a. The sliding portion 223a is movably disposed in the sliding groove 221a, and a part of the structure of the sliding portion 223a is exposed to the outside. The locking portion 223b is locked in the locking groove 222a. The locking member 223 is pushed upward and moves along the sliding groove 221a, whereby the locking portion 223b of the locking member 223 is disengaged from the locking groove 222a. This releases the lock between the first rod portion 221 and the second rod portion 222, and the first rod portion 221 rotates inward relative to the second rod portion 222 to enter a folded state.

[0058] Referring to FIG. 4, the sliding part 223a further includes a groove 223c for easily moving the sliding part. A user can apply force to the groove 223c of the sliding part 223a to drive the sliding part 223a to move downward. Furthermore, the support assembly 2 further includes a first elastic reset member 6 configured to reset the locking member 223. In this embodiment, the first elastic reset member 6 is disposed in the sliding groove 221a and is located between the first rod part 221 and the locking member 223. When the locking member 223 is pushed upward, the locking member 223 compresses the first elastic reset member 6, thereby disengaging the locking part 223b from the locking groove 222a. When no force is applied to the locking member 223, the locking part 223b is locked in the locking groove 222a again by the elastic restoring force of the first elastic reset member 6. In this embodiment, the first elastic reset member 6 is a compression spring, but is not limited thereto. It can be seen that in another embodiment, one end of the locking member 223 is movably disposed on the second rod portion 222 , in which case the other end of the locking member 223 is locked within the first rod portion 221 .

[0059] 1 and 2, the bed frame structure 100 further includes two support legs 5. The two support legs 5 are disposed below the bottom assembly 1 at intervals. Specifically, the bottom assembly 1 includes four bottom rods 11. The four bottom rods 11 are fixedly connected in sequence to form a closed rectangular structure. The two support legs 5 are respectively connected to two opposing bottom rods 11. A second rod portion 222 is fixed to each bottom rod 11. In this embodiment, the support legs 5 are pivotally connected to the bottom rods 11, and the support legs 5 rotate inwardly relative to the bottom rods 11 to be in a folded state in order to fold the bed frame structure 100. In addition, the bottom assembly 1 further includes a horizontal rod 12 and a sliding assembly 13. The horizontal rod 12 is connected between the two opposing bottom rods 11. One end of each sliding assembly 13 is slidably disposed on the transverse rod 12, and the other end of the sliding assembly 13 is pivotally connected to the support leg 5. The sliding assembly 13 slides along the transverse rod 12 and rotates the support leg 5 to the folded state. Specifically, the sliding assembly 13 includes a sliding sleeve 131 and an interlocking member 132. The sliding sleeve 131 is slidably sleeved on the transverse rod 12. One end of the interlocking member 132 is pivotally connected to the sliding sleeve 131, and the other end of the interlocking member 132 is pivotally connected to the support leg 5. The sliding sleeve 131 is driven to slide along the transverse rod 12, thereby rotating the interlocking member 132, which in turn rotates the support leg 5 inwardly to the folded state.

[0060] As shown in FIG. 2 , the sliding assembly 13 further includes a locking member 133. The locking member 133 is disposed in the sliding sleeve 131 and selectively locked in the positioning portion of the horizontal rod 12. The locking member 133 is operated to be disengaged from the positioning portion of the horizontal rod 12, thereby allowing the sliding sleeve 131 to slide along the horizontal rod 12. Specifically, the locking member 133 includes a hook portion 133a and an unlocking button portion 133b connected to the hook portion 133a. The hook portion 133a is selectively locked to the positioning portion of the horizontal rod 12, and the unlocking button portion 133b is pivotally connected to the sliding sleeve 131. The unlocking button portion 133b rotates to disengage the hook portion 133a from the positioning portion of the horizontal rod 12, thereby unlocking the sliding sleeve 131 and allowing the sliding sleeve 131 to move along the horizontal rod 12. In another embodiment, the locking member 133 may be slidably locked within the transverse rod 12. The locking member 133 is pulled out, which disengages the locking member 133 from the transverse rod 12 and allows the sliding sleeve 131 to slide along the transverse rod 12.

[0061] 2, the sliding assembly 13 further includes a second elastic reset member 7 configured to reset the unlock button portion 133b. The second elastic reset member 7 is disposed between the unlock button portion 133b and the sliding sleeve 131. When the unlock button portion 133b is pressed and rotated, the unlock button portion 133b compresses the second elastic reset member 7 and rotates the hook portion 133a to disengage from the horizontal rod 12, thereby allowing the sliding sleeve 131 to move along the horizontal rod 12. When the sliding sleeve 131 slides in the reverse direction, the unlock button portion 133b rotates due to the elastic restoring force of the second elastic reset member 7 and rotates the hook portion 133a, so that the hook portion 133a is engaged with the horizontal rod 12 again. The second elastic reset member 7 may be, but is not limited to, a compression spring.

[0062] 10 to 13, a positioning portion configured to position the locking member 133 is provided on the horizontal rod 12. The positioning portion includes a first locking position 121 and a second locking position 122. In this embodiment, the first locking position 121 and the second locking position 122 are rectangular grooves formed on the horizontal rod 12. When the hook portion 133a of the locking member 133 is locked at the first locking position 121, the support leg 5 is locked in an unfolded state relative to the bottom assembly 1. When the hook portion 133a of the locking member 133 is locked at the second locking position 122, the support leg 5 is locked in a folded state relative to the bottom assembly 1. The unlock button portion 133b rotates to rotate the hook portion 133a, thereby disengaging the hook portion 133a from the first locking position 121 or the second locking position 122, thereby unlocking the sliding sleeve 131. In this manner, the sliding sleeve 131 is movable along the transverse rod 12, thereby rotating the support leg 5 via the interlocking member 132 to unfold or fold.

[0063] 1 and 7 to 9, the support leg 5 includes a support leg body 51 and an extendable portion 52. The upper end of the support leg body 51 is pivotally connected to the bottom assembly 1, and the extendable portion 52 is disposed at the lower end of the support leg body 51 so as to be movable laterally. In this embodiment, when the support leg body 51 rotates inward relative to the bottom assembly 1 to be in a folded state, the extendable portion 52 can be moved to be retracted into the support leg body 51. In this manner, the volume of the bed frame structure 100 after folding can be further reduced, which is more convenient for storage than other methods. In addition, the support leg 5 further includes a leg wheel 53, which is pivotally connected to the extendable portion 52. The leg wheel 53 can drive the entire bed frame structure 100 to move.

[0064] Referring to FIG. 1, each armrest 3 is provided with an armrest lock assembly 31 configured to lock the armrest to the top of the support assembly 2 or unlock the armrest from the top of the support assembly 2. The armrest lock assembly 31 can adopt an existing lock assembly. For example, the armrest lock assembly 31 may adopt a combination of an existing pressing member, a rotating wheel, a steel wire, and an armrest lock member 133, and pull the steel wire by driving and rotating the rotating wheel and pressing the pressing member. In this way, the steel wire is used to pull the armrest lock member 133 to disengage it from the first rod portion 221 of the support rod 22. This allows the armrest 3 to be unlocked and moved downward. This structure is widely used in children's products such as cribs, and therefore will not be described in detail in this specification.

[0065] The specific operating principle of the bed frame structure 100 will be briefly explained below with reference to Figs.

[0066] When the bed frame structure 100 needs to be folded, the armrest 3 can be driven to slide downward to the lowest position below the pivot connection point 21 of the support rod 22. Then, the locking member 223 is pushed upward and moved along the sliding groove 221a, so that the locking portion 223b of the locking member 223 is disengaged from the second rod portion 222. In this way, the lock between the first rod portion 221 and the second rod portion 222 is released. The first rod portions 221 on both sides rotate inward to the folded state. Next, the sliding sleeve 131 is unlocked by pressing the unlock button portion 133b of the locking member 133 to rotate the hook portion 133a to disengage from the positioning portion of the horizontal rod 12. The sliding sleeves 131 on both sides are moved inward along the horizontal rod 12, so that the support legs 5 are rotated to the folded state via the interlocking member 132. Finally, the telescopic portion 52 is driven to retract into the support leg body 51. In this way, the volume of the folded bed frame structure 100 can be further reduced, which is more convenient for storage than other methods.

[0067] Based on the above, the support assembly 2 of the above bed frame structure 100 is provided with a pivot connection point 21 that allows both ends of the support assembly to rotate into a folded state, both ends of the armrest 3 can be arranged on the two support assemblies 2 so that they can move up and down, and the two armrests 3 can be slid downward to a position below the pivot connection point 21, and then the two support assemblies 2 rotate inwardly to a folded state. Finally, the support legs 5 on both sides are respectively rotated inwardly and folded, thereby folding the bed frame structure 100. The folding is simple and convenient, the structure is simple, and the manufacturing cost is low. Therefore, this bed frame structure is suitable for widespread use.

[0068] 14 to 16, a bed frame structure 100 according to another embodiment includes a bed body 10 having an accommodation space, and support legs 5 capable of supporting the bed body 10. When in use, an infant or small child can be placed in the accommodation space. Each support leg 5 is foldable relative to the bed body 10, and has an unfolded state and a folded state.

[0069] The support leg 5 includes a support section 331 and a foot section 350 connected to the support section 331. The foot section 350 includes a main body section 351 and an expandable section 52. The expandable section 52 is expandable relative to the main body section 351 and has an expanded state (see FIG. 15) and a retracted state (see FIG. 16). When the support leg 5 is in a folded state, the expandable section 52 is restricted from switching from the retracted state to the expanded state. When the support leg 5 is in an unfolded state, the expandable section 52 can be switched from the retracted state to the extended state. That is, when the support leg 5 is in a folded state, the expandable section 52 is operated to retract to the retracted state relative to the main body section 351, and the expansion and contraction of the expandable section 52 is restricted. When the support leg 5 is in an unfolded state, the expandable section 52 is freely expandable and contractable. When not in use, the support leg 5 is folded relative to the bed body 10 to be in a folded state, thereby restricting the telescopic part 52 from switching from the retracted state to the extended state, effectively reducing the space occupied by the bed frame structure and facilitating storage and transportation. When the support leg 5 is in an unfolded state, the telescopic part 52 is switched from the retracted state to the extended state to facilitate use.

[0070] It should be further noted that the main body part 351 is connected to the support part 331, and both ends of the main body part 351 are provided with the telescopic parts 52. When the telescopic parts 52 are in an extended state relative to the main body part 351, the bed frame structure 100 can be used as a baby bed. When the bed frame structure 100 is used as a bedside bed, the telescopic parts 52 are retracted when it abuts against an adult bed, so that the telescopic parts 52 are retracted relative to the main body part 351, and the bedside bed approaches the adult bed, making it easier to use the bed frame structure.

[0071] 14 to 19, the bed frame structure 100 further includes a drive unit 70 (see FIG. 22) provided on each support leg 5 and a locking mechanism. When the support leg 5 is in a folded state, the drive unit 70 is operated to lock the locking mechanism, thereby restricting the telescopic unit 52 from switching from the retracted state to the extended state. When the support leg 5 is in an unfolded state, the drive unit 70 unlocks the locking mechanism, and the telescopic unit 52 is switched from the retracted state to the extended state. The bed body 10 has four sides and a bottom. In one embodiment, when the support leg 5 is folded into the bottom of the bed body 10 and is in a folded state, the drive unit 70 is driven by the bed body 10 to lock the locking mechanism. It should be noted that any part of the bed body 10 that drives the drive unit 70 to lock the locking mechanism is included in the scope of protection of the present application. Further, the bed body 10 includes a frame 311 and a first part 315 disposed at the bottom of the frame 311 (see FIG. 14). When the support leg 5 is folded into the first part 315 and is in a folded state, the driving part 70 is driven by the first part 315 to lock the locking mechanism. The bed body 10 further includes a connecting member 313, one end of which is slidably connected to the first part 315 and the other end of which is connected to the support leg 5. The connecting member 313 is slid to fold the support leg 5 relative to the bed body 10. In this embodiment, the frame 311 includes an upper frame 3111, a lower frame 3113, and a plurality of posts 3115 located between the upper frame 3111 and the lower frame 3113. The first part 315 is located in the lower frame 3113, and the structure formed by the lower frame 3113 may be understood to be the bottom of the bed body 10.

[0072] 20 to 25, the driving unit 70 has a locking member 3711. The locking mechanism includes a locking member 355 connected to the telescopic unit 52. The positioning member 553 is disposed on the locking member 355. When the telescopic unit 52 is operated to be in the retracted state, the telescopic unit 52 is fixedly connected to the locking member 355, so that the telescopic unit 52 drives the locking member 355 to retract toward the fixed unit 57, and the positioning member 553 can approach the fixed unit 57. When the support leg 5 is operated to be folded relative to the bed body 10, the driving unit 70 is compressed by the first part 315, and the positioning member 553 is locked to the locking member 3711. When the positioning member 553 is locked to the locking member 3711, the telescopic unit 52 is always in the retracted state, that is, the telescopic unit 52 is locked and cannot be extended. When the support leg 5 is operated to be in an unfolded state relative to the frame 311, the positioning member 553 is unlocked from the locking member 3711. That is, when the support leg 5 is operated to be in an unfolded state, the first part 315 does not apply pressure to the driving part 70. When the driving part 70 extends to drive the locking member 3711 and the positioning member 553 to release the lock, the reset part 59 separates the expandable part 52 from the fixed part 57 to be in an extended state.

[0073] 20 to 25, the locking mechanism further includes a fixed portion 57 attached to the main body portion 351, and a reset portion 59 located between the expandable portion 52 and the fixed portion 57. The main body portion 351 has a hollow structure, and the locking member 355, the fixed portion 57, and the reset portion 59 are located in the hollow structure. One end of the locking member 355 is fixedly connected to the expandable portion 52, and the other end of the locking member 355 is slidably disposed on the fixed portion 57. The locking member 355 also has a sliding portion 551, and the fixed portion 57 is provided with a sliding member 571 extending into the sliding portion 551. The sliding portion 551 and the sliding member 571 are slidably fitted together. When the telescopic part 52 abuts against the adult bed, the telescopic part 52 overcomes the elastic force of the reset part 59 by the external force and retreats into the hollow structure of the main body part 351, which drives the locking member 355 to slide toward the fixed part 57. Due to the guiding action of the sliding member 571 and the sliding part 551, the telescopic part 52 retreats into the main body part 351 and enters a retreated state. In addition, the fixed part 57 is formed with a first mounting groove 573, the telescopic part 52 is formed with a second mounting groove 531, and the reset part 59 is located between the first mounting groove 573 and the second mounting groove 531. Specifically, the reset part 59 may include, but is not limited to, a spring. In order to make the bed frame structure 100 more convenient to move, a moving part 533 is disposed on the telescopic part 52.

[0074] 20 to 25, a restoring member 90 is disposed between the fixed portion 57 and the driving portion 70. The restoring member 90 tends to drive the driving portion 70 to move away from the fixed portion 57. Specifically, the restoring member 90 may include, but is not limited to, a spring. The driving portion 70 includes a driving portion body 71 and a driving pin 73 located in the driving portion body 71. The body portion 351 has a through hole, and the driving portion body 71 is located in the hollow structure of the body portion 351. In one embodiment, the driving portion body 71 and the driving pin 73 are integrally formed to extend the service life. When the driving pin 73 extends from the through hole, the support leg 5 is in a folded state, and the first portion 315 presses the driving pin 73. The driving portion body 71 is disposed with a first positioning portion 713. The fixing portion 57 is disposed with a second positioning portion 575 that engages with the first positioning portion 713. The driving part 70 is compressed by the first part 315, and the second positioning part 575 is located in the first positioning part 713 to prevent the driving part 70 from vibrating. Specifically, the second positioning part 575 is connected to the sliding member 571 and is located on the side of the sliding member 571 facing the driving part 70. In order for the first part 315 to press the driving pin 73 more accurately and stably, the main body part 351 is provided with a restricting part 513 for positioning the first part 315. The restricting part 513 includes a first restricting part 5131 and a second restricting part 5133 (see FIG. 19), and the number of the restricting parts 513 can be adjusted as necessary, and is not limited thereto. After extending from the through hole, the driving pin 73 is located between the first restricting part 5131 and the second restricting part 5133. When the support leg 5 is in the folded state, the first part 315 presses the driving pin 73 accurately.

[0075] 27 to 34, the lock member 355 is provided with a resistance structure 80. The telescopic part 52 is operated to drive the sliding member 571 to move over the resistance structure 80. That is, when the applied external force reaches a predetermined value, the telescopic part 52 drives the sliding member 571 to overcome the resistance structure 80. That is, when the telescopic part 52 is fully extended or expanded, a certain thrust is required to overcome the resistance structure 80 in order to enable the sliding member to overcome the resistance structure 80, and the telescopic part 52 can be prevented from being extended or retracted arbitrarily. For example, the thrust can be set to be >50 Newtons (N), but is not limited thereto. In this way, the sliding member can overcome the resistance structure 80 until the telescopic part 52 is fully extended. Therefore, the thrust can be set according to actual needs. In one embodiment, the resistance structure 80 is provided in the sliding part 551. Specifically, the resistance structure 80 includes a buffer part 83, and the buffer part 83 protrudes into the sliding part 551. When the buffer portion 83 is compressed by the sliding member 571, the buffer portion 83 is elastically deformed.

[0076] In addition, the resistance structure 80 further includes a hollow portion 81. The hollow portion 81 is disposed at a position corresponding to the buffer portion 83 on one or both sides of the sliding portion 551. When the buffer portion 83 is compressed by the sliding member 571, the buffer portion 83 is elastically deformed toward the hollow portion 81. As shown in FIG. 29 to FIG. 34, when the telescopic portion 52 changes between the retracted state and the fully extended state, the telescopic portion 52 cannot freely expand or contract, since the telescopic portion cannot be folded or unfolded unless the resistance of the resistance structure 80 is overcome. In this way, it is safe and reliable. The number of the resistance structures 80 may be one, two, or more, but is not limited thereto, and the structure and shape of the resistance structure are not limited to those described in this embodiment. The external force applied to the telescopic portion 52 is used to overcome the resistance of the resistance structure 80 by pushing or pulling. Specifically, in this embodiment, when a thrust in the K direction in the figures is utilized, as shown in Figures 33 and 34, the expandable portion 52 is in the retracted state, and the sliding member 571 is moved toward the buffer portion 83 by the thrust (see Figures 31 and 32). When the thrust overcomes the elastic force of the buffer portion 83, the sliding member overcomes the buffer portion 83 and becomes fully extended (see Figures 19 and 20).

[0077] Hereinafter, the operating principle of the bed frame structure 100 will be specifically described with reference to Figs.

[0078] When the telescopic portion 52 is in a stretched state relative to the main body portion 351, the bed frame structure 100 stands stably and can be used as a baby bed.

[0079] When the bed frame structure 100 needs to be used as a bedside bed, the bed frame structure 100 is moved close to the adult bed. The telescopic part 52 abuts against the adult bed, and the telescopic part 52 overcomes the elastic force of the reset part 59 by an external force and retreats into the main body part 351, thereby causing the lock member 355 to slide toward the fixed part 57. Due to the guiding action of the sliding member 571 and the sliding part 551, the telescopic part 52 retreats into the main body part 351 and enters a retreated state, and the bed frame structure 100 approaches the adult bed.

[0080] When the bed frame structure 100 is no longer needed, the bed frame structure 100 can be folded. The support leg 5 is operated to be folded toward the bed body 10 to be in the folded state, the first part 315 presses the driving pin 73, and the driving pin 73 drives the driving part body 71 to move toward the fixed part 57, overcoming the elastic force of the restoring member 90. Next, the telescopic part 52 is operated to be retracted, and the positioning member 553 on the locking member 355 is driven to approach the fixed part 57 until the engaging member 3711 is engaged with the positioning member 553, and the telescopic part 52 is locked in the retracted state.

[0081] When the bed frame structure 100 needs to be unfolded, the support leg 5 is operated to be in the unfolded state, and the first part 315 does not apply pressure to the driving part 70. The restoring member 90 causes the driving part 70 to be extended to unlock the locking member 3711 from the positioning member 553. And the resetting part 59 causes the telescopic part 52 to be separated from the fixed part 57 to be in the extended state. The connecting member 313 is assembled to the support leg 5, and the bed frame structure 100 can be used normally.

[0082] Compared with the prior art, when the bed frame structure 100 is not in use, the telescopic part 52 retracts from the main body part 351 and is in a retracted state. In addition, by folding the support leg 5 relative to the bed main body 10 and in a folded state, the telescopic part 52 is restricted from moving from the retracted state to the extended state, effectively reducing the space occupied by the bed frame structure and facilitating storage and transportation. When the support leg 5 is in an unfolded state, the telescopic part 52 is changed from the retracted state to the extended state, facilitating use.
