[0002] In related technologies, the two ends of the bed frame's support mechanism are pivotally connected to the corresponding frames. The longitudinal span of the bed frame is changed by moving the first support member relative to the second support member, making the bed frame height adjustable for user convenience or allowing the bed frame to occupy a smaller volume in its retracted state for easy transport. During the process of adjusting the bed frame height via the support mechanism, the first and second support members may disengage from each other along a second direction. Utility Model Content

Detailed Implementation

[0044] It should be noted that, unless otherwise specified, the embodiments and technical features in the embodiments of this application can be combined with each other, and the detailed descriptions in the specific implementation should be understood as explanations of the purpose of this application and should not be regarded as undue limitations on this application.

[0045] In related technologies, a bed frame includes a support mechanism and a frame. The support mechanism has frames at both ends. The support mechanism includes a first support member and a second support member. The span of the support mechanism along the second direction is changed by moving the first support member relative to the second support member, thus changing the span of the frame along the second direction, and consequently, the height of the bed frame. When the first support member extends relative to the second support member along the second direction, the span of the frame along the second direction increases, and the bed frame is in a higher position. When the first support member retracts relative to the second support member along the second direction, the distance between the frames along the second direction decreases accordingly, and the bed frame is in a retracted state. In the retracted state, the bed frame is in a lower position, or occupies a smaller volume for easier transport. During the extension or retraction of the first support member relative to the second support member, since neither the first nor the second support member has a limiting structure, the first support member may extend too far along the second direction relative to the second support member, causing the first support member to detach from the second support member along the second direction.

[0046] Therefore, this disclosure provides a bed frame, please refer to the embodiments provided. Figures 1-5 The bed frame includes a support mechanism according to any embodiment of this application. The height of the bed frame can be adjusted via the support mechanism.

[0047] In some embodiments, the bed frame also includes at least two foldable frames. Figure 1 This is a view of the bed frame in normal use; simply place a mattress on top of the bed frame to use it.

[0048] For example, such as Figure 1 The two frames are arranged alternately on the left and right.

[0049] In some embodiments, each frame includes at least two spaced-apart sub-frames. For example... Figure 1 Each frame has sub-frames arranged at intervals, and the two ends of the support mechanism are pivotally connected to the sub-frames.

[0050] For example, the height of the frame can be increased or decreased by adjusting the support mechanism.

[0051] In this embodiment of the disclosure, the height of the frame is changed by adjusting the support mechanism, so that the bed frame can switch between a higher and lower height, which is convenient for users and also convenient for transportation.

[0052] In some embodiments, please refer to Figures 1-5 At least one support mechanism is a first support mechanism 100, and at least one support mechanism is a second support mechanism 200. The first support mechanism 100 is pivotally connected between two adjacent frames, so that the two adjacent frames can rotate around the first support mechanism 100. The frame includes at least two spaced sub-frames 303, and the second support mechanism 200 is pivotally connected between two corresponding sub-frames 303 of the same frame.

[0053] For example, please refer to Figure 11 , Figure 11 A schematic diagram of the bed frame folding process is shown. The two side frames of the first support mechanism 100 rotate toward the first support mechanism 100 to fold into a folded state. During the folding process, the second support mechanism 200 rotates relative to the two sub-frames 303 of the same frame.

[0054] This disclosure provides a bed frame; please refer to [link / reference]. Figures 1-5 The bed frame includes a first support mechanism 100, a second support mechanism 200, and at least two foldable frames. The first support mechanism 100 and the second support mechanism 200 can be the support mechanisms of corresponding embodiments of this disclosure. The first support mechanism 100 is pivotally connected between two adjacent frames, allowing the two adjacent frames to rotate around the first support mechanism 100. Each frame includes at least two spaced-apart subframes 303, and the second support mechanism 200 is pivotally connected between two corresponding subframes 303 of the same frame.

[0055] This disclosure provides a support mechanism; please refer to [link / reference]. Figures 1-6 , Figure 10 The support mechanism includes a first support member 1 and a second support member 2. The second support member 2 is movably installed on the first support member 1 along a second direction R2, and the second direction R2 is arranged to intersect with the first direction R1.

[0056] It should be noted that the longitudinal direction of the bed frame is the second direction, R2.

[0057] For example, the second direction R2 is perpendicular to the first direction R1.

[0058] The second support member 2 is movably mounted on the first support member 1 along the second direction R2, meaning that the second support member 2 is mounted on the first support member 1, the second support member 2 is movable relative to the first support member 1, and the second support member 2 moves relative to the first support member 1 along the second direction R2.

[0059] The ability of the second support member 2 to move relative to the first support member 1 refers to the relative movement between the first support member 1 and the second support member 2. For example, the first support member 1 may move along the second direction R2 while the second support member 2 remains stationary; or, the second support member 2 may move along the second direction R2 while the first support member 1 remains stationary; or, both the first support member 1 and the second support member 2 may move.

[0060] For example, there can be one frame, and the height of the frame can be adjusted by moving the first support 1 relative to the second support 2. For example, please refer to [link to example]. Figure 1 There can be two frames, and the two frames can be pivotally connected to opposite sides of the first support mechanism 100.

[0061] For example, the first support member 1 and the second support member 2 are respectively connected to the frame. The first support member 1 can be stationary relative to the correspondingly connected frame. The second support member 2 can be stationary relative to the correspondingly connected frame.

[0062] For example, the first support member 1 and the second support member 2 are respectively pivotally connected to the frame. Both the first support member 1 and the second support member 2 are rotatable relative to the frame.

[0063] By moving the first support member 1 relative to the second support member 2 along the second direction R2, the span of the support mechanism along the second direction R2 is changed, thereby adjusting the span between the frames along the second direction R2, allowing the bed frame to switch between higher and lower height states.

[0064] For example, please refer to Figures 1-5The frame includes at least two spaced-apart subframes 303. One end of a first support member 1 is disposed at a corresponding subframe 303, and / or one end of a second support member 2 is disposed at a corresponding subframe 303. For example, one frame is a first frame 301, and the other frame is a second frame 302. One subframe 303 of the first frame 301 is disposed at one end of the first support member 1 of the corresponding support mechanism, and the other subframe 303 of the first frame 301 is disposed at one end of the second support member 2 of the corresponding support mechanism. One subframe 303 of the second frame 302 is disposed at one end of the first support member 1 of the corresponding support mechanism, and the other subframe 303 of the second frame 302 is disposed at one end of the second support member 2 of the corresponding support mechanism.

[0065] For example, please refer to Figures 1-5 The first support mechanism 100 is pivotally connected between two adjacent frames. For example, one end frame is the first frame 301, and the other end frame is the second frame 302. The two sub-frames 303 of the first frame 301 are pivotally connected to the left side of the first support mechanism 100, and the two sub-frames 303 of the second frame 302 are pivotally connected to the right side of the first support mechanism 100.

[0066] For example, the first support member 1 of the first support mechanism 100 is pivotally connected to the upper sub-frame 303 of the two frames. The second support member 2 of the first support mechanism 100 is pivotally connected to the lower sub-frame 303 of the two frames. For example, one end of the second support mechanism 200 along the second direction R2 is disposed on one sub-frame 303 of the corresponding frame, and the other end of the second support mechanism 200 along the second direction R2 is disposed on another sub-frame 303 of the corresponding frame. For example, one end of the second support mechanism 200 along the second direction R2 is connected to one sub-frame 303 of the first frame 301, and the other end of the second support mechanism 200 along the second direction R2 is connected to another sub-frame 303 of the first frame 301. One end of the second support mechanism 200 along the second direction R2 is connected to one sub-frame 303 of the second frame 302, and the other end of the second support mechanism 200 along the second direction R2 is connected to another sub-frame 303 of the second frame 302.

[0067] For example, the first support member 1 of the second support mechanism 200 is connected to a sub-frame 303 of one end of the frame. The second support member 2 of the second support mechanism 200 is connected to another sub-frame 303 of the same frame. For example, one end of the frame is a first frame 301, and the other end of the frame is a second frame 302. The first support member 1 is connected to a sub-frame 303 of the first frame 301 at one end along the second direction R2, and the second support member 2 is connected to a sub-frame 303 of the first frame 301 at one end along the second direction R2. The first support member 1 is connected to a sub-frame 303 of the second frame 302 at one end along the second direction R2, and the second support member 2 is connected to a sub-frame 303 of the second frame 302 at one end along the second direction R2.

[0068] In some embodiments, please refer to Figures 6-10 The first support member 1 includes a first bearing plate 11 and a constraint member that are connected to each other. The constraint member is located on one side of the first bearing plate 11 along a first direction R1, where the first direction R1 is the thickness direction of the first bearing plate 11.

[0069] For example, the first bearing plate 11 is provided with a constraint member on at least one side along the third direction R3, and the third direction R3 is arranged to intersect with the first direction R1 and the second direction R2 respectively.

[0070] For example, the first bearing plate 11 is provided with constraint members on opposite sides along the third direction R3.

[0071] In this embodiment of the present disclosure, the second support member 2 is constrained by the constraint member on one side of the first bearing plate 11 along the first direction R1.

[0072] In some embodiments, please refer to Figures 6-10 At least one constraint is a first constraint 12, and the first constraint 12 includes a first limiting member 122.

[0073] In some embodiments, please refer to Figures 6-10 The first constraint member 12 includes a first flange 121 connected to the first limiting member 122, and the first flange 121 is connected to one side of the first bearing plate 11 along the first direction R1.

[0074] The first flange 121 is connected to one side of the first support plate 11 along the first direction R1, and the first flange 121 protrudes from the first support plate 11 along the first direction R1.

[0075] In this embodiment of the present disclosure, the first flange 121 connected to one side of the first bearing plate 11 along the first direction R1 can better support the first bearing plate 11, which is beneficial to improving the overall bearing capacity of the first support member 1.

[0076] In this embodiment of the present disclosure, the first flange 121 extends along the second direction R2 and is perpendicularly connected to the first support plate 11.

[0077] In some embodiments, please refer to Figures 6-10 The second support member 2 includes a second bearing plate 21.

[0078] For example, the constraint can constrain the second bearing plate 21.

[0079] See some implementation columns. Figures 6-10 The second support member 2 also includes a guide member 22 connected to the second support plate 21, and the guide member 22 is located on one side of the second support plate 21 along the first direction R1.

[0080] For example, the constraint can constrain the guide 22.

[0081] For example, the constraint can constrain the second carrier plate 21 and / or the guide 22.

[0082] For example, the guide 22 is located on the side of the second support plate 21 opposite to the first support plate 11.

[0083] In some embodiments, please refer to Figures 6-10 The guide member 22 includes a second limiting member 222, which can move relative to the first limiting member 122 along the second direction R2 to abut against the first limiting member 122 to restrict the first support member 1 and the second support member 2 from disengaging.

[0084] For example, the thickness direction of the first bearing plate 11 is substantially the same as that of the second bearing plate 21.

[0085] For example, the second limiting member 222 is located on one side of the second bearing plate 21 along the first direction R1.

[0086] For example, the second limiting member 222 is located on the side of the second bearing plate 21 opposite to the first bearing plate 11 along the first direction R1.

[0087] For example, the first limiting member 122 and the second limiting member 222 are both located on the same side of the second bearing plate 21 along the first direction R1.

[0088] In some embodiments, please refer to Figures 6-10 The guide 22 also includes a second flange 221 connected to the second limiting member 222, and the second flange 221 is connected to one side of the second bearing plate 21 along the first direction R1.

[0089] For example, please refer to Figures 6-10The second flange 221 is located on the side of the second bearing plate 21 that is away from the first bearing plate 11 along the first direction R1.

[0090] For example, please refer to Figures 6-10 The second support member 2 is located on one side of the first bearing plate 11 along the first direction R1.

[0091] In this embodiment of the present disclosure, the second flange 221 extends along the second direction R2 and is perpendicularly connected to the second support plate 21.

[0092] In some embodiments, please refer to Figures 6-10 The support mechanism also includes a locking device 3, which is used to lock the first support member 1 and the second support member 2 in the locked state. The first support member 1 can move relative to the second support member 2 when the locking device 3 is in the unlocked state.

[0093] For example, when it is necessary to adjust the position of the first support member 1 relative to the second support member 2, the locking device 3 is unlocked, allowing the first support member 1 to move relative to the second support member 2. This movement adjusts the height of the frame along the second direction R2 to a suitable position, resulting in a higher bed frame. After the first support member 1 has moved to the adjusted position relative to the second support member 2, the locking device 3 is locked, locking both the first and second support members 1 and 2. In this locked state, the second support member 2 and the first support member 1 are virtually unable to move along the second direction R2.

[0094] For example, the second direction R2 is arranged in the vertical direction.

[0095] In this embodiment, the first flange 121 connected to one side of the first support plate 11 can better support the first support plate 11, and can improve the load-bearing capacity of the first support member 1 along the second direction R2 when the weight of the first support member 1 is relatively light. The second flange 221 connected to one side of the second support plate 21 can better support the second support plate 21, and can improve the load-bearing capacity of the second support member 2 along the second direction R2 when the weight of the second support member 2 is relatively light. The first flange 121 and the second flange 221 can also constrain each other to a certain extent to limit the movement of the first support member 1 relative to the second support member 2 along the arrangement direction of the first flange 121 and the second flange 221, thereby better guiding the movement of the first support member 1 relative to the second support member 2 along the second direction R2. The movement of the first support member 1 and the second support member 2 is limited by the first limiting member 122 on the first support member 1 and the second limiting member 222 on the second support member 2 abutting along the second direction R2. When the first support member 1 and the second support member 2 move away from each other to a preset position along the second direction R2, the first limiting member 122 and the second limiting member 222 abutting along the second direction R2, restricting the first support member 1 and the second support member 2 from moving further away along the second direction R2, thereby restricting the first support member 1 and the second support member 2 from disengaging. This makes it easier to adjust the position of the first support member 1 relative to the second support member 2 along the second direction R2.

[0096] In some embodiments, please refer to Figures 6-10 The first support member 1 has multiple adjustment holes 15, which are arranged sequentially along the second direction R2. The second support member 2 has a locking hole 24. A locking device 3 passes through the locking hole 24 and the corresponding adjustment hole 15 to lock the first support member 1 and the second support member 2.

[0097] For example, the first support plate 11 is provided with at least two adjustment holes 15, which are arranged along the second direction R2. The second support plate 21 is provided with a locking hole 24. The locking device 3 can be inserted into the locking hole 24 and the adjustment holes 15 at different positions so that the moving distance of the first support member 1 and the second support member 2 is adjustable.

[0098] For example, adjustment hole 15 is formed in first support plate 11.

[0099] For example, locking hole 24 is formed in second support plate 21.

[0100] It should be explained that "multiple" refers to two or more.

[0101] For example, with the locking device 3 in the unlocked state, the first support member 1 is moved to align the locking hole 24 with the corresponding adjustment hole 15. Then, the locking device 3 is passed through the locking hole 24 and the aligned adjustment hole 15 to lock the first support member 1 and the second support member 2. The first support member 1 and the second support member 2 are locked in the adjusted position. The locking device 3 is then moved out of the locking hole 24 and the adjustment hole 15 to unlock the locking device 3.

[0102] For example, the first support member 1 has two adjustment holes 15, and the second support member 2 has one locking hole 24.

[0103] For example, both the adjustment hole 15 and the locking hole 24 are circular in shape, and the diameter of the adjustment hole 15 and the diameter of the locking hole 24 are the same.

[0104] For example, the adjusting hole 15 can be moved to be coaxial with the locking hole 24. Projected along the axial direction of the locking hole 24, the projection area of ​​the locking hole 24 and the projection area of ​​the adjusting hole 15 are concentric.

[0105] For example, when the locking device 3 passes through the locking hole 24 and the adjusting hole 15, the locking hole 24 and the corresponding adjusting hole 15 are coaxial. Projected along the axial direction of the locking hole 24, the projection area of ​​the locking hole 24 and the projection area of ​​the adjusting hole 15 are concentric.

[0106] In some embodiments, please refer to Figure 8 and Figure 9 The locking device 3 includes a locking body 31 and a support shaft 32 and an end stop 33 connected to each other. The support shaft 32 passes through the locking hole 24 and the corresponding adjustment hole 15. The end stop 33 abuts against one of the first support member 1 and the second support member 2 along the axial direction of the support shaft 32. The locking body 31 is threadedly connected to the support shaft 32. The locking body 31 abuts against the other of the first support member 1 and the second support member 2 along the axial direction of the support shaft 32.

[0107] For example, when projected axially along the support shaft 32, both the projection area of ​​the support shaft 32 and the projection area of ​​the end stop 33 are circular. The diameter of the support shaft 32 is smaller than the diameter of the end stop 33. The diameter of the support shaft 32 is less than or equal to the diameter of the locking hole 24, and the diameter of the support shaft 32 is less than or equal to the diameter of the adjusting hole 15. The diameter of the end stop 33 is greater than or equal to the diameter of the locking hole 24, and the diameter of the end stop 33 is greater than or equal to the diameter of the adjusting hole 15.

[0108] For example, the locking body 31 can be a nut. For instance, the nut can be a wing nut.

[0109] For example, the support shaft 32 and the end stop 33 can be configured as a pin or bolt.

[0110] In this embodiment, the support shaft 32 passes through the locking hole 24 and the corresponding adjustment hole 15 to restrict the movement of the first support member 1 relative to the second support member 2. The locking body 31 is threadedly connected to the support shaft 32 to clamp both the portion of the first support member 1 and the portion of the second support member 2 between the locking body 31 and the end stop 33.

[0111] For example, please refer to Figure 12 Locking device 3 can be a pin.

[0112] For example, please refer to Figure 12 and Figure 13 The pin includes a pin body 34, a limiting ring 35, and a stop boss 36. The limiting ring 35 is mounted on the pin body 34. The maximum radial dimension of the limiting ring 35 along the pin body 34 is greater than the diameter of the pin body 34, and the maximum radial dimension of the limiting ring 35 along the pin body 34 is greater than the diameter of the locking hole 24 and / or the diameter of the adjusting hole 15. The stop boss 36 protrudes radially from the pin body 34. The maximum radial span between the pin body 34 and the stop boss 36 along the pin body 34 is greater than the diameter of the locking hole and / or the diameter of the adjusting hole. Both the first support member and the second support member can be constrained axially between the stop boss 36 and the limiting ring 35 along the pin body 34.

[0113] For example, please refer to Figure 12 The maximum radial dimension of the limiting ring 35 along the nail body 34 is D7, and the diameter of the nail body 34 is D8, where D7 > D8.

[0114] For example, please refer to Figure 13 The maximum span of the nail body 34 and the stop boss 36 along the radial direction of the nail body 34 is D9, where D9 > D8.

[0115] For example, please refer to Figure 12 The stop boss 36 can be connected to the nail body 34. Through compression deformation, the stop boss 36 passes through the locking hole 24 and the adjusting hole 15, constraining the first support member 1 and the second support member 2 along the axial direction of the nail body 34 between the stop boss 36 and the limiting ring 35, thus locking the device. Through compression deformation, the stop boss 36 can be reversed and passed through the locking hole 24 and the adjusting hole 15, allowing the nail body 34 to be removed from the first support member 1 and the second support member 2, unlocking the device.

[0116] For example, please refer to Figure 12The nail body 34 has a mounting hole 341. The stop boss 36 is movably mounted in the mounting hole 341 of the nail body 34 along the radial direction of the nail body 34. The locking device 3 also includes an elastic element 37 located in the mounting hole 341. The elastic element 37 abuts against the stop boss 36 and the nail body 34 respectively. The nail body 34 limits the stop boss 36 to prevent the stop boss 36 from disengaging from the mounting hole 341. By squeezing, the stop boss 36 passes through the locking hole 24 and the adjusting hole 15. Under the action of external force, the stop boss 36 retracts back into the mounting hole 341. After passing through the locking hole 24 and the adjusting hole 15, the stop boss 36 is reset under the action of the elastic element 37 to constrain the first support 1 and the second support 2 along the axial direction of the nail body 34 between the stop boss 36 and the limiting ring 35, and the locking device 3 is locked. By squeezing, the stop boss 36 is forced to pass through the locking hole 24 and the adjusting hole 15 in the opposite direction. Under the action of external force, the stop boss 36 retracts back into the mounting hole 341. After passing through the locking hole 24 and the adjusting hole 15 in the opposite direction, the stop boss 36 is reset under the action of the elastic member 37, which allows the nail body 34 to be moved out from the first support member 1 and the second support member 2, and the locker 3 is unlocked.

[0117] For example, the elastic element 37 can be a spring.

[0118] In some embodiments, please refer to Figures 6-10 The first flange 121 and the second flange 221 are arranged along a third direction R3. The third direction R3 is arranged to intersect with the first direction R1 and the second direction R2. The second flange 221 is located between the second bearing plate 21 and the corresponding first flange 121 along the third direction R3. The first limiting member 122 is partially covered on the second flange 221. The first limiting member 122 is located on the side of the first flange 121 facing the corresponding second flange 221 along the third direction R3.

[0119] For example, the third direction R3 is perpendicular to the first direction R1 and the second direction R2, respectively.

[0120] In this embodiment, during the user's movement of the first support 1 relative to the second support 2, the user's hand primarily contacts the side of the first flange 121 facing away from the second flange 221 along the third direction R3, i.e., the outer side of the first flange 121. The second limiting member 222 is located on the side of the first flange 121 facing the corresponding second flange 221 along the third direction R3, reducing the possibility of the user contacting the second limiting member 222 during operation and minimizing the possibility of being scratched by it. The first limiting member 122 is connected to the first flange 121 and covers the second flange 221, meaning one end of the first limiting member 122 protrudes towards the side facing the second flange 221, i.e., the inner side of the first flange 121, further reducing the possibility of the user contacting and being scratched by the first limiting member 122 during operation. Furthermore, the first limiting member 122, which is connected to the first flange 121, partially covers the second flange 221, so that the second flange 221 is partially located between the first limiting member 122 and the first bearing plate 11 along the first direction R1. The first limiting member 122 and the first bearing plate 11 can effectively limit the second support member 2 along the first direction R1, thereby guiding the first support member 1 to move relative to the second support member 2 along the second direction R2 as much as possible.

[0121] Exemplarily, the arrangement of the first limiting member 122 and the second limiting member 222 is not limited. Exemplarily, the first limiting member 122 is located on the side of the second flange 221 away from the second bearing plate 21 along the third direction R3, and the second limiting member 222 covers the first flange 121.

[0122] In some embodiments, please refer to Figures 7-9 The second support member 2 is located on the side of the first bearing plate 11 facing the first flange 121 along the first direction R1, and the size of the first flange 121 along the first direction R1 is larger than the size of the second flange 221 along the first direction R1.

[0123] For example, please refer to Figures 6-10 The first support member 1 is fitted onto the second support member 2.

[0124] For example, please refer to Figure 9 The first flange 121 has a dimension of D1 along the first direction R1, and the second flange 221 has a dimension of D2 along the first direction R1, where D1 > D2.

[0125] In this embodiment, the second support member 2 is positioned on the side of the first bearing plate 11 facing the first flange 121, allowing the first support member 1 to guide the movement of the second support member 2 with a relatively simple structure. The dimension of the first flange 121 along the first direction R1 is larger than that of the second flange 221 along the first direction R1, resulting in a smaller or even negligible protrusion of the second flange 221 from the first flange 121 along the first direction R1. This reduces the degree to which the first limiting member 122 protrudes from the side of the first flange 121 away from the first bearing plate 11 along the first direction R1, thereby improving the load-bearing capacity of the first limiting member 122. During the process of the first limiting member 122 moving to abut against the second limiting member 222, the first limiting member 122 can better withstand the impact of the second limiting member 222.

[0126] It is understood that the dimensions of the first flange 121 and the second flange 221 are not limited. For example, the dimension of the first flange 121 along the first direction R1 may be less than or equal to the dimension of the second flange 221.

[0127] In some embodiments, please refer to Figures 6-10 The second limiting member 222 protrudes along the first direction R1 from the side of the first flange 121 away from the first bearing plate 11.

[0128] For example, please refer to Figures 6-10 The second limiting member 222 is located on the side of the second flange 221 that is away from the second bearing plate 21 along the first direction R1.

[0129] For example, the second limiting member 222 protrudes from the side of the first limiting member 122 away from the first bearing plate 11 along the first direction R1.

[0130] In this embodiment, the second limiting member 222 protrudes from the side of the first flange 121 away from the first bearing plate 11 along the first direction R1, so that the second limiting member 222 can be firmly abutted against the first limiting member 122 along the second direction R2, reducing the possibility of the first limiting member 122 and the second limiting member 222 slipping off due to the deformation of the first limiting part under force during the process of the second limiting part and the first limiting member 122 abutting against each other along the first direction R1, thereby reducing the possibility of the first support member 1 and the second support member 2 separating from each other.

[0131] It is understood that the arrangement of the second limiting member 222 is not limited. For example, the surface of the first flange 121 facing away from the first support plate 11 along the first direction R1 is the first surface, and the second limiting member 222 is located on the side of the first surface facing the first support plate 11 along the first direction R1, that is, the second limiting member 222 does not protrude from the first flange 121.

[0132] In some embodiments, please refer to Figures 6-10The first limiting member 122 is located on the side of the first flange 121 away from the first bearing plate 11 along the first direction R1, and the second flange 221 is located between the first bearing plate 11 and the first limiting member 122 along the first direction R1. The second limiting member 222 protrudes from the side of the second flange 221 away from the second bearing plate 21 along the first direction R1.

[0133] In this embodiment, the first limiting member 122 is located on the side of the first flange 121 facing away from the first support plate 11 along the first direction R1. A large space exists between the first limiting member 122 and the first support plate 11 along the first direction R1 to accommodate the second flange 221, effectively guiding the second flange 221 to move along the second direction R2 between the first limiting member 122 and the first support plate 11. The second limiting member 222 protrudes from the side of the second flange 221 facing away from the second support plate 21 along the first direction R1. The portion of the first limiting member 122 extending along the third direction R3 can abut against the second limiting member 222, allowing the first limiting member 122 and the second limiting member 222 to abut against each other along the first direction R1 with a relatively simple structure.

[0134] It is understood that the specific structure of the first limiting member 122 is not limited. For example, the first limiting member 122 includes a limiting body and an auxiliary member connected to each other. The second flange 221 is located between the limiting body and the first support plate 11 along the first direction R1. The auxiliary member is located on the side of the limiting body facing the first support plate 11 along the first direction R1. The second flange 221 is located between the auxiliary member and the first flange 121 along the third direction R3. The second limiting member 222 is located on the side of the second flange 221 away from the first flange 121 along the third direction R3. The second limiting member 222 does not protrude from the second flange 221.

[0135] In some embodiments, please refer to Figure 7 and Figure 8 Along the second direction R2, the size of the first limiting member 122 is smaller than the size of the first flange 121, and the size of the second limiting member 222 is smaller than the size of the second flange 221.

[0136] For example, please refer to Figure 8 The dimension of the first limiting member 122 along the second direction R2 is D3, and the dimension of the first flange 121 along the second direction R2 is D4. <D4。

[0137] For example, please refer to Figure 8 The second limiting member 222 has a dimension of D5 along the second direction R2, and the second flange 221 has a dimension of D6 along the second direction R2. <D6。

[0138] In this embodiment of the present disclosure, along the second direction R2, the size of the first limiting member 122 is smaller than the size of the first flange 121, and the size of the second limiting member 222 is smaller than the size of the second flange 221. This allows space to be left in a limited space for the first support member 1 to move relative to the second support member 2 along the second direction R2, and also allows the first limiting member 122 and the second limiting member 222 to abut well.

[0139] It is understood that the dimensions of the first limiting member 122 and the second limiting member 222 are not limited. For example, along the second direction R2, the dimension of the first limiting member 122 may be greater than or equal to the dimension of the first flange 121, and the dimension of the second limiting member 222 may be greater than or equal to the dimension of the second flange 221.

[0140] In some embodiments, please refer to Figures 6-10 The first support member 1 has a first mounting portion 13 for mounting the frame, and the second limiting member 222 is located between the first mounting portion 13 and the first limiting member 122 along the second direction R2. The second support member 2 has a second mounting portion 23 for mounting the frame, and the first limiting member 122 is located between the second mounting portion 23 and the second limiting member 222 along the second direction R2.

[0141] For example, the second limiting member 222 moves along the second direction R2 between the first mounting portion 13 and the first limiting member 122, and the first limiting member 122 moves along the second direction R2 between the second mounting portion 23 and the second limiting member 222.

[0142] In this embodiment of the present disclosure, the second limiting member 222 can be limited by the frame mounted on the first mounting part 13 and / or the first limiting member 122 can be limited by the frame mounted on the second mounting part 23, thereby preventing the frame from excessively approaching along the second direction R2.

[0143] For example, please refer to Figure 6 and Figure 10 The first mounting portion 13 has a first hole 131, through which a fastener passes to connect the first mounting portion 131 to the frame. The first support member 1 is pivotally connected to the frame via the first mounting portion 13, allowing the frame to rotate about the axis of the first hole 131 when the bed frame is folded or unfolded. The second mounting portion 23 has a second hole 231, through which a fastener passes to connect the second mounting portion 231 to the frame. The second support member 2 is pivotally connected to the frame via the second mounting portion 23, allowing the frame to rotate about the axis of the second hole 231 when the bed frame is folded or unfolded.

[0144] For example, please refer to Figure 6 and Figure 10Projecting along the second direction R2, the projection area of ​​the first flange 121 and the projection line of the central axis of the first hole 131 are arranged alternately, and the projection area of ​​the second flange 221 and the projection line of the central axis of the second hole 231 are arranged alternately.

[0145] In some embodiments, please refer to Figures 6-10 The first bearing plate 11 is provided with constraint members on both sides. The arrangement direction of the constraint members on both sides is intersected with the first direction R1 and the second direction R2 respectively. The second support member 2 is located between at least a portion of one side constraint member and at least a portion of the other side constraint member along the arrangement direction of the constraint members on both sides.

[0146] For example, please refer to Figure 1 , Figure 3 , Figure 6 and Figure 7 Of the two side constraints, each side constraint is the first constraint 12.

[0147] For example, please refer to Figure 1 , Figure 2 , Figure 4 , Figure 5 and Figure 10 Of the two constraint members, one constraint member is the first constraint member 12, and the other constraint member is the second constraint member 14.

[0148] For example, please refer to Figures 6-10 The constraint members on both sides are arranged along the third direction R3, and the third direction R3 is arranged to intersect with the first direction R1 and the second direction R2 respectively.

[0149] In this embodiment, the first bearing plate 11 is provided with constraint members on both sides. The arrangement direction of the constraint members on both sides is intersected with the first direction R1 and the second direction R2, so that the constraint members on both sides can constrain the second support member 2 on the corresponding side of the arrangement direction of the constraint members on both sides, thereby restricting the movement of the first support member 1 relative to the second support member 2 along the arrangement direction of the constraint members on both sides, thereby better guiding the first support member 1 to move relative to the second support member 2 along the second direction R2.

[0150] It is understood that the arrangement of the constraint is not limited. For example, the constraint is located on one side of the first bearing plate 11 along the third direction R3.

[0151] In some embodiments, please refer to Figure 1 , Figure 3 , Figure 6 and Figure 7Both sides of the constraint member are first constraint members 12. The second bearing plate 21 is provided with guide members 22 on both sides. The arrangement direction of the guide members 22 on both sides is intersected with the first direction R1 and the second direction R2 respectively. Each side of the first constraint member 12 is provided with a corresponding guide member 22.

[0152] For example, please refer to Figure 6 and Figure 7 The third party is arranged in the left-right direction R3 as shown in the figure. The first limiting member 122 of the first constraint member 12 on the left side of the first support plate 11 can abut against the second limiting member 222 of the guide member 22 on the left side of the first support plate 11 along the second direction R2. The first limiting member 122 of the first constraint member 12 on the right side of the first support plate 11 can abut against the second limiting member 222 of the guide member 22 on the right side of the first support plate 11 along the second direction R2.

[0153] In this embodiment, both sides of the constraint members are first constraint members 12, and each first constraint member 12 on each side has a corresponding guide member 22. The first limiting member 122 of each first constraint member 12 and the second limiting member 222 of the corresponding guide member 22 can abut against each other along the second direction R2, so that when the first limiting member 122 and the second limiting member 222 abut against each other, the first support member 1 along the arrangement direction of the two constraint members and the second support member 2 along the arrangement direction of the two guide members 22 can be subjected to force relatively evenly. Furthermore, both sides are provided with a first flange 121 and a second flange 221. The first flange 121 on both sides can provide good support for the corresponding sides of the first bearing plate 11, improving the bearing capacity of the first support member 1 along the second direction R2. The second flange 221 on both sides can provide good support for the corresponding sides of the second bearing plate 21, improving the bearing capacity of the second support member 2 along the second direction R2.

[0154] In some embodiments, please refer to Figure 1 , Figure 2 , Figure 4 , Figure 5 and Figure 10 One side of the constraint member is the first constraint member 12, and the guide member 22 is located on the side of the second bearing plate 21 facing the first constraint member 12 along the arrangement direction of the two side constraint members. The other side of the constraint member is the second constraint member 14, which has a guide rib 141. The second bearing plate 21 is located between the first bearing plate 11 and the guide rib 141 along the first direction R1, and the guide rib 141 spans between the opposite ends of the first bearing plate 11 along the second direction R2.

[0155] It should be explained that the guide rib 141 spans between the two opposite ends of the first bearing plate 11 along the second direction R2. The end faces of the two ends of the first bearing plate 11 along the second direction R2 are reference faces. The guide rib 141 spans between the two reference faces along the second direction R2. The guide rib 141 is located on both sides of the center position of the first bearing plate 11 along the second direction R2.

[0156] For example, please refer to Figure 2 and Figure 10 The third-party constraint 14 is arranged along the left-right direction shown in the figure, and the first limiting member 122 of the first constraint member 12 on the left side of the first bearing plate 11 can abut against the second limiting member 222 of the guide member 22 on the left side of the first bearing plate 11 along the second direction R2. The second constraint member 14 on the right side of the first bearing plate 11 has a guide rib 141, and the right side of the second bearing plate 21 along the first direction R1 is located between the first bearing plate 11 and the guide rib 141.

[0157] For example, the space enclosed by the second constraint member 14 and the first support plate 11 for accommodating the second support plate 21 is C-shaped, U-shaped or V-shaped.

[0158] In this embodiment, the first limiting member 122 of the first constraint member 12 on one side and the second limiting member 222 of the corresponding guide member 22 abut against each other along the first direction R1, which can restrict the separation of the first support member 1 and the second support member 2. The guide rib 141 is arranged across the opposite ends of the first bearing plate 11 along the second direction R2, so that the guide rib 141 can guide and constrain the second bearing plate 21 with a larger dimension along the second direction R2, reducing the possibility of the first support member 1 flipping along the first direction R1 during the movement relative to the second support member 2, and making the movement of the first support member 1 relative to the second support member 2 more stable. The guide member 22 is located on the side of the second bearing plate 21 facing the first constraint member 12 along the arrangement direction of the two side constraints. The side of the second bearing plate 21 facing the second constraint member 14 along the arrangement direction of the two side constraints does not have a second flange 221 corresponding to the guide member 22, and the dimension of the first support member 1 along the first direction R1 at the corresponding position of the guide rib 141 can be smaller.

[0159] In some embodiments, please refer to Figure 2 and Figure 10 The second bearing plate 21 contacts the guide rib 141 and the first bearing plate 11 on opposite sides along the first direction R1, respectively.

[0160] In this embodiment, the guide rib 141 is almost attached to the second support plate 21 to constrain the second support plate 21 along the first direction R1. The two sides of the second support plate 21 along the first direction R1 are in contact with the guide rib 141 and the first support plate 11, respectively. This can minimize the space between the guide rib 141 and the first support plate 11 along the first direction R1, so that the size of the first support member 1 along the first direction R1 at the corresponding position of the guide rib 141 is minimized as much as possible.

[0161] For example, the second bearing plate 21 is arranged at intervals with the guide rib 141.

[0162] In some embodiments, please refer to Figure 2 , Figure 5 and Figure 10 The guide rib 141 extends from one end of the first bearing plate 11 to the other end of the first bearing plate 11 along the second direction R2.

[0163] In this embodiment of the present disclosure, the guide rib 141 extends continuously from one end to the other end, which is beneficial for the guide rib 141 to guide the second bearing plate to move in the second direction R2 between the guide rib 141 and the first bearing plate 11 more smoothly.

[0164] In some embodiments, the guide rib 141 includes a plurality of sub-ribs, which are arranged sequentially at intervals between one end and the other end of the first bearing plate 11 along the second direction R2.

[0165] It should be explained that multiple sub-reinforcements are arranged sequentially and spaced apart between one end and the other end of the first bearing plate 11 along the second direction R2. The end faces of the two ends of the first bearing plate 11 along the second direction R2 are reference faces. The sub-reinforcements are located between the two reference faces along the second direction R2, and there are at least a portion of the sub-reinforcements on both sides of the center position of the first bearing plate 11 along the second direction R2.

[0166] In this embodiment, the second bearing plate 21 can be guided well by the guide rib 141 along a longer distance in the second direction R2, while also saving materials, reducing weight, and lowering costs.

[0167] In some embodiments, the first support member 1 and the second support member 2 are respectively pivotally connected to the corresponding subframe 303.

[0168] In some embodiments, when the frame is in the unfolded state, the first flange 121 and the second flange 221 abut against the space between the two subframes 303.

[0169] For example, when the frame is in the unfolded state, the first flange 121 and the second flange 221 of the second support mechanism 200 abut against the two sub-frames 303. When the bed frame is in the unfolded state, it can prevent the sub-frames 303 from rotating around the axis of the first hole 131 toward the first flange 121 and around the axis of the second hole 231 toward the second flange 221, so that the sub-frames 303 of the bed frame can only fold in one direction, thereby avoiding the problem of the bed frame collapsing during unfolded use.

[0170] In some embodiments, please refer to Figure 2 When the frame is in the unfolded state, the first flange 121 and the second flange 221 of the second support mechanism 200 abut against the two sub-frames 303.

[0171] In some embodiments, please refer to Figures 6-10 The second support member 2 is located at least partially between the constraint member and the first bearing plate 11 along the first direction R1 to restrict the second support member 2 from disengaging from the first support member 1 along the first direction R1.

[0172] For example, the first support plate 11 is provided with a constraint on at least one side along the third direction R3. The constraint restricts the movement of the first support 1 relative to the second support 2 along the third direction R3.

[0173] For example, the first support plate 11 is provided with constraint members on opposite sides along the third direction R3. The constraint members on both sides constrain the second support member 2 and restrict its movement along the third direction R3.

[0174] The second support member 2 is at least partially located between the constraint member and the first bearing plate 11 along the first direction R1. That is, at least a portion of the constraint member, the second support member 2, and the first bearing plate 11 are arranged sequentially along the first direction R1. At least a portion of the constraint member is located on the side of the second support member 2 away from the first bearing plate 11 along the first direction R1. The projection area of ​​the at least a portion of the constraint member on the side of the second support member 2 away from the first bearing plate 11 along the first direction R1 partially overlaps with the projection area of ​​the second support member 2 along the first direction R1. The projection area of ​​the second support member 2 along the first direction R1 and the projection area of ​​the first bearing plate 11 along the first direction R1 at least partially overlap.

[0175] For example, the first bearing plate 11 is provided with a constraint member on one side along the third direction R3, and the third direction R3 is arranged to intersect with the first direction R1 and the second direction R2 respectively.

[0176] For example, the first support plate 11 is provided with constraint members on both sides along the third direction R3. The constraint on both sides helps to smoothly guide the first support member 1 to move relative to the second support member 2 along the second direction R2.

[0177] In this embodiment of the present disclosure, the second support member 2 is located at least partially between the constraint member and the first bearing plate 11 along the first direction R1. The second support member 2 is constrained by the constraint member and the first bearing plate 11 along the first direction R1, thereby restricting the movement of the first support member 1 relative to the second support member 2 along the first direction R1, thereby better guiding the movement of the first support member 1 relative to the second support member 2 along the second direction R2.

[0178] In some embodiments, please refer to Figures 6-10 One of the constraint members is a first constraint member 12, which includes a first flange 121 and a first limiting member 122. The first flange 121 is connected to one side of the first support plate 11 along the thickness direction, which is a third direction R3. The third direction R3 intersects with the first direction R1 and the second direction R2. The first limiting member 122 is connected to the side of the first flange 121 facing the second support member 2 along the third direction R3. The second support member 2 is at least partially located between the first limiting member 122 and the first support plate 11 along the first direction R1.

[0179] For example, please refer to Figures 6-10 The first constraint member 12 is located on one side of the first bearing plate 11 along the third direction R3.

[0180] For example, please refer to Figures 6-10 The first bearing plate 11 has first constraint members 12 on both sides along the third direction R3.

[0181] In this embodiment, the first flange 121 can better support the first bearing plate 11 to improve the bearing capacity of the first bearing plate 11 along the second direction R2. The second support member 2 is well constrained along the first direction R1 by the first limiting member 122 and the first bearing plate 11.

[0182] In some embodiments, please refer to Figure 10 One of the constraint members is the second constraint member 14, which has a guide rib 141. The second bearing plate 21 is located between the first bearing plate 11 and the guide rib 141 along the first direction R1. The guide rib 141 spans across the opposite ends of the first bearing plate 11 along the second direction R2.

[0183] For example, please refer to Figure 10 One of the constraint members is the second constraint member 14.

[0184] For example, both sides of the constraint are the second constraint 14.

[0185] In this embodiment of the disclosure, the guide rib 141 and the first bearing plate 11 constrain the second bearing plate 21 along the first direction R1.

[0186] In some embodiments, please refer to Figures 6-10 The first limiting member 122 is located on the side of the first flange 121 that is away from the first bearing plate 11 along the first direction R1, and the second support member 2 is located entirely between the first limiting member 122 and the first bearing plate 11 along the first direction R1.

[0187] In this embodiment of the present disclosure, the second support member 2 is constrained between the first limiting member 122 and the first bearing plate 11 along the first direction R1. By limiting the second support member 2 along the first direction R1 through the first limiting member 122 and the first bearing plate 11, the movement of the second support member 2 relative to the first support member 1 along the first direction R1 can be restricted.

[0188] In some embodiments, please refer to Figures 6-10 The second support member 2 includes a second bearing plate 21 and a guide member 22. The guide member 22 includes a second flange 221, which is connected to the side of the second bearing plate 21 away from the first bearing plate 11 along the first direction R1. The second flange 221 is located at least partially between the first limiting member 122 and the first bearing plate 11 along the first direction R1.

[0189] In this embodiment, the second flange 221 can better support the second bearing plate 21 to improve the bearing capacity of the second support member 2 along the second direction R2. The second flange 221 is constrained by the first limiting member 122 and the first bearing plate 11 along the first direction R1, which restricts the first support member 1 from moving relative to the second support member 2 along the first direction R1.

[0190] In some embodiments, please refer to Figure 4 and Figure 5 The subframe 303 has a mounting surface 304. The first support member 1 and the second support member 2 of the second support mechanism 200 are pivotally connected to the subframe 303 at the corresponding mounting surface 304. The guide rib 141 is located on the side of the corresponding first bearing plate 11 facing the mounting surface 304 along the first direction R1. The projection area of ​​the guide rib 141 along the first direction R1 partially overlaps with the projection area of ​​the mounting surface 304 along the first direction R1.

[0191] For example, the first flange 121 and the second flange 221 are located between the two sub-frames 303 along the second direction R2. Along the second direction R2, the projection area of ​​the first flange 121 and the projection area of ​​the sub-frame 303 at least partially overlap, and the projection area of ​​the second flange 221 and the projection area of ​​the sub-frame 303 at least partially overlap.

[0192] In this embodiment, the guide rib 141 is located on the side of the first bearing plate 11 facing the mounting surface 304 along the first direction R1. Since the size of the first support member 1 along the first direction R1 at the corresponding position of the guide rib 141 is small, even if the projection area of ​​the guide rib 141 along the first direction R1 partially overlaps with the projection area of ​​the mounting surface 304 along the first direction R1, the first support member 1 can still be attached to the mounting surface 304 as much as possible at the corresponding position of the mounting surface 304, so that the first support member 1 and the corresponding mounting bracket can be installed more firmly, reducing space occupation. The projection area of ​​the guide rib 141 along the first direction R1 partially overlaps with the projection area of ​​the mounting surface 304 along the first direction R1. The guide rib 141 extends along the second direction R2 to the corresponding position on the mounting surface 304. The bent guide rib 141 on the second constraint member 14 can strengthen the first support member 1 at the corresponding position on the mounting surface 304, so that the first support member 1 can better bear the load of the frame.

[0193] It is understood that the arrangement of the second support mechanism 200 is not limited. For example, the guide rib 141 is located on the side of the corresponding first bearing plate 11 facing away from the mounting surface 304 along the first direction R1.

[0194] The above are merely preferred embodiments of this application and are not intended to limit the scope of this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the scope of protection of this application.
