[0032] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0033] In the description of the present invention, it should be understood that the features defined as “first” or “second” may explicitly or implicitly include one or more of the features.

[0034] Reference below Figure 1-Figure 8 A bed frame 100 according to an embodiment of the present invention is described.

[0035] like Figure 1-Figure 3 As shown, the bed frame 100 according to the embodiment of the present invention includes: a first bed rail 1, a second bed rail 2 and a folding mechanism 3, and the folding mechanism 3 includes: an operating part 31, a clamping part 32, a clamping reset member 33 and an adjusting part 34.

[0036] Specifically, the first end of the operating part 31 is rotatably connected to the first bed rod 1, and the second end of the operating part 31 is rotatably connected to the second bed rod 2. The clamping part 32 is movably arranged on the operating part 31 between the mating position and the disengaging position. When in the mating position, the clamping part 32 is mated with the first bed rod 1 to make the first bed rod 1 relatively fixed to the second bed rod 2. When in the disengaging position, the clamping part 32 is disengaged from the first bed rod 1 to make the first bed rod 1 movable relative to the second bed rod 2. The clamping reset member 33 is connected between the clamping part 32 and the operating part 31 to always drive the clamping part 32 to move toward the mating position. The adjusting part 34 is slidably arranged on the operating part 31, and the adjusting part 34 has an adjusting surface 3411 in contact with the clamping part 32. The adjusting surface 3411 is configured to drive the clamping part 32 to move between the mating position and the disengaging position when the adjusting part 34 slides.

[0037] It can be understood that, since the first end of the operating portion 31 is rotatably connected to the first bed rod 1, the operating portion 31 has only one degree of rotational freedom relative to the first bed rod 1. When the clamping portion 32 is in the mating position, the degree of rotational freedom of the operating portion 31 is also constrained, which is equivalent to the folding mechanism 3 and the first bed rod 1 forming a whole, and the first bed rod 1 and the second bed rod 2 are relatively fixed. In addition, the clamping reset member 33 often drives the clamping portion 32 to move toward the mating position, so the fixation of the first bed rod 1 and the second bed rod 2 is relatively stable, which improves the safety performance of the bed frame 100. When the clamping portion 32 is in the disengaged position, the clamping portion 32 is disengaged from the first bed rod 1, the folding mechanism 3 is rotatable relative to the first bed rod 1, the folding mechanism 3 is rotatable relative to the second bed rod 2, and the first bed rod 1 is rotatable relative to the second bed rod 2, that is, the bed frame 100 can be folded.

[0038] Through the foregoing analysis, the bed frame 100 according to the embodiment of the present invention is a foldable bed frame. When the adjusting portion 34 is pulled to disengage the clamping portion 32, the bed frame can be folded freely. When the adjusting portion 34 is released, the clamping portion 32 can automatically reset. When the bed frame is opened, the clamping portion 32 can maintain the clamping state under the action of the clamping reset member 33. Therefore, the folding mechanism 3 has a relatively simple structure. During use, the bed frame 100 has a high safety performance. When not in use, the bed frame 100 can be folded to save space.

[0039] In some embodiments, Figure 4 As shown, the first bed bar 1 includes two support bars, which are connected as a whole at one end, and the folding mechanism 3 is arranged between the two support bars. The folding mechanism 3 includes two clamping parts 32, and the two clamping parts 32 are matched with the two support bars in a one-to-one correspondence. The folding mechanism 3 is arranged between the two support bars of the first bed bar 1 to save installation space.

[0040] In some embodiments, Figure 3 and Figure 5 As shown, the adjusting portion 34 includes a connecting segment 342 and two adjusting segments 341 . The two adjusting segments 341 are respectively arranged at both ends of the connecting segment 342 and arranged in the same direction. Each connecting segment 342 is provided with an adjusting surface 3411 . The adjusting portion 34 generally slides in a direction perpendicular to the connecting segment 342 .

[0041] Specifically, Figure 5 As shown, the operating part 31 is provided with perforations 311 on the parts located on both sides of the two adjustment sections 341, and the two support rods are provided with clamping holes 11 opposite to the corresponding perforations 311, and the two clamping parts 32 are respectively formed as pins, and the two pins are respectively matched in the perforations 311, and one end of each pin is matched with the corresponding adjustment surface 3411, and the other end of each pin is inserted into the corresponding clamping hole 11 when in the matched position, and each pin is pulled out from the clamping hole 11 when in the disengaged position. The restriction of the perforations 311 allows the clamping part 32 to only expand and contract in the perforations 311, ensuring that the head of the clamping part 32 is always matched with the adjustment surface 3411, thereby limiting the range of movement of the clamping part and improving the structural reliability.

[0042] More specifically, if Figure 3-Figure 5 As shown, the surfaces of the two adjustment sections 341 facing each other constitute adjustment surfaces 3411 respectively, and the two adjustment surfaces 3411 are formed as inclined surfaces that are inclined in a direction away from the connecting section 342 and toward each other. Each adjustment surface 3411 is provided with a sliding hole 3412 extending along the sliding direction of the adjustment portion 34, each pin fits in the corresponding sliding hole 3412, and one end of each pin has a clamping head that contacts the adjustment surface 3411. This design can, on the one hand, set the two adjustment surfaces 3411 inside the adjustment portion 34 to avoid interference in the adjustment, and on the other hand, increase the contact area between the adjustment portion 34 and the operating portion 31, thereby improving the stability of the adjustment portion 34 when sliding.

[0043] It can be understood that in the sliding direction of the adjusting portion 34, when the adjusting portion 34 slides in one direction, the distance between the two pins gradually decreases, so the two pins will be pulled out of the locking holes 11 respectively. When the two pins are completely out of the locking holes 11, the folding mechanism 3 can rotate relative to the first bed frame 100. When the adjusting portion 34 slides in another direction, the distance between the two pins gradually increases, so the two pins will be gradually inserted into the locking holes 11 respectively.

[0044] In some embodiments, Figure 3-Figure 5 As shown, the folding mechanism 3 further includes a support block 35 , which is disposed on the operating portion 31 and between the two adjustment sections 341 , and the clamping reset member 33 is connected between the clamping head and the support block 35 .

[0045] Positioning crosses are respectively provided on opposite sides of the support block 35 . Both the two clamping reset members 33 are springs. One end of each spring is sleeved on the positioning cross and the other end is sleeved on the clamping head of the clamping portion 32 .

[0046] Specifically, Figure 3 As shown, a limit groove 351 is defined between the support block 35 and the operating portion 31 for limiting the sliding direction of the adjustment section 341. This design allows the adjustment section 341 to slide only in a direction perpendicular to the connecting section 342, thereby ensuring the sliding direction of the adjustment section 34 and preventing the adjustment section 34 from being skewed or stuck.

[0047] In some embodiments, Figure 3 As shown, a receiving cavity 343 is defined in the second end of the operating portion 31, and the adjusting portion 34 and the clamping reset member 33 are both arranged in the receiving cavity 343. In this way, the adjusting portion 34 and the clamping reset member 33 can be protected to prevent the parts from being lost.

[0048] In some embodiments, Figure 3-Figure 5 As shown, the folding mechanism 3 further includes an adjustment reset member 36, which is connected between the operating portion 31 and the adjustment portion 34. In this way, when the user releases the adjustment portion 34, the adjustment portion 34 automatically resets, facilitating the next folding operation of the folding mechanism 3.

[0049] like Figure 4-Figure 6 As shown, in some embodiments, the folding mechanism 3 further includes a handle 37, which is slidably disposed on the first end of the operating portion 31, and the handle 37 is connected to the adjusting portion 34 via a rope 38. The user can directly fold the bed frame 100 by pulling the handle 37, so that the user does not need to directly contact the adjusting portion 34.

[0050] The handle 37 is used to pull the adjusting portion 34 . On the one hand, the handle 37 can be set larger to facilitate holding. On the other hand, it is away from the adjusting portion 34 and the clamping portion 32 to improve the safety of use.

[0051] Refer to the following Figure 1-Figure 8 The specific structure and folding process of a bed frame 100 according to an embodiment of the present invention are introduced.

[0052] like Figure 1-Figure 3As shown, the bed frame 100 of this embodiment includes two first bed bars 1, two second bed bars 2 and two folding mechanisms 3. The two first bed bars 1 and the two second bed bars 2 are arranged alternately, and the bed frame 100 is formed into a square frame shape, and a folding mechanism 3 is arranged in each first bed bar 1.

[0053] Specifically, the bed frame 100 can be regarded as being composed of two groups of rods connected end to end, each of which includes a folding mechanism 3 and a first bed rod 1 and a second bed rod 2 connected to the folding mechanism 3. In each rod group, one end of the folding mechanism 3 is rotatably connected to the second bed rod 2 of the same group, and the other end is rotatably connected to the frame formed by the first bed rod 1 of the same group. One end of the first bed rod 1 is rotatably connected to the second bed rod 2 of the other group, and the other end is in contact with the second bed rod 2 of the same group but not connected.

[0054] Each folding mechanism 3 includes: an operating portion 31, a clamping portion 32, a clamping reset member 33, an adjusting portion 34, a supporting block 35, an adjusting reset member 36, a handle 37 and a rope 38. Each first bed bar 1 includes two support rods, and each folding mechanism 3 includes two clamping portions 32. The two clamping portions 32 are matched with the two support rods in a one-to-one correspondence, and the two clamping portions 32 are located at the diagonal positions of the bed frame 100.

[0055] like Figure 3 As shown, the first end of the operating part 31 is rotatably connected to the first bed rod 1, the second end of the operating part 31 is rotatably connected to the second bed rod 2, and an accommodating cavity 343 is defined in the second end of the operating part 31, and the adjusting part 34 and the snap-on reset member 33 are both arranged in the accommodating cavity 343.

[0056] like Figure 3 As shown, the clamping portion 32 is movably provided on the operating portion 31 between a mating position and a disengaging position. In the mating position, the clamping portion 32 is mated with the first bed rod 1 to fix the first bed rod 1 and the second bed rod 2 relatively. In the disengaging position, the clamping portion 32 is disengaged from the first bed rod 1 to allow the first bed rod 1 to rotate relative to the second bed rod 2.

[0057] like Figure 3 As shown, the locking reset member 33 is connected between the locking portion 32 and the operating portion 31 to normally drive the locking portion 32 to move toward the matching position.

[0058] like Figure 3As shown, the adjusting portion 34 is slidably disposed on the operating portion 31, and the adjusting portion 34 has an adjusting surface 3411 in contact with the clamping portion 32, and the adjusting surface 3411 is configured to drive the clamping portion 32 to move between the mating position and the disengaging position when the adjusting portion 34 slides. Specifically, the adjusting portion 34 includes a connecting section 342 and two adjusting sections 341, and the two adjusting sections 341 are respectively disposed at both ends of the connecting section 342 and arranged in the same direction, and each adjusting section 341 is provided with an adjusting surface 3411, and the surfaces of the two adjusting sections 341 facing each other respectively constitute the adjusting surfaces 3411, and the two adjusting surfaces 3411 are formed as inclined surfaces inclined in a direction away from the connecting section 342 and approaching each other. Each adjusting surface 3411 is provided with a sliding hole 3412 extending along the sliding direction of the adjusting portion 34, and the adjusting portion 34 generally slides in a direction perpendicular to the connecting section 342.

[0059] Specifically, Figure 5 As shown, the side walls of the accommodating cavity 343 facing the two adjustment sections 341 are respectively provided with through holes 311, and the two support rods are respectively provided with clamping holes 11 opposite to the corresponding through holes 311. The two clamping parts 32 are respectively formed as pins, and the two pins are respectively engaged in the through holes 311. One end of each pin is engaged with the corresponding adjustment surface 3411. When in the engaged position, the other end of each pin is inserted into the corresponding clamping hole 11, and when in the disengaged position, each pin is pulled out from the clamping hole 11.

[0060] More specifically, each pin fits into the corresponding sliding hole 3412 , and one end of each pin has a clamping head in contact with the adjustment surface 3411 .

[0061] The support block 35 is disposed in the accommodating cavity 343 and between the two adjusting sections 341 . The clamping reset member 33 is connected between the clamping head and the support block 35 . A limiting groove 351 for limiting the sliding direction of the adjusting section 341 is defined between the support block 35 and the operating portion 31 .

[0062] The adjustment reset member 36 is connected between the operating portion 31 and the adjustment portion 34 , and the adjustment reset member 36 is a spring.

[0063] like Figure 5 and Figure 6 As shown, the handle 37 is slidably disposed on the first end of the operating portion 31 , and the handle 37 is connected to the adjusting portion 34 via a rope 38 .

[0064] The folding process of the bed frame 100 according to one embodiment of the present invention is as follows:

[0065] When the bed frame 100 is in normal use, the pin is inserted into the clamping hole 11, and the folding mechanism 3 and the first bed frame 100 become a whole. At this time, the first bed frame 100 cannot rotate relative to the second bed frame 100. Figure 7As shown, when the bed frame 100 needs to be folded, the handle 37 is pulled to make the adjustment part 34 slide in the direction close to the handle 37. It can be understood that when the adjustment part 34 slides in the direction close to the handle 37, the distance between the pin and the connecting section 342 continues to increase. Since the two adjustment surfaces 3411 are inclined surfaces facing away from the connecting section 342 (away from the handle 37) and approaching each other, the two pins will gradually be pulled out of the clamping holes 11. When the pins are completely out of the clamping holes 11, the folding mechanism 3 can rotate in the frame formed by the first bed frame 1 in the same group, and the folding mechanism 3 can rotate relative to the second bed rod 2 in the same group, and the first bed rod 1 can rotate relative to the second bed rod 2 in another group. Therefore, the overall folding can be completed by simply folding the folding mechanism 3 towards the second bed rod 2 in the same group and folding the first bed rod 1 towards the second bed rod 2 in another group. The folding result is shown as follows. Figure 8 shown.
