DETAILED DESCRIPTION

[0036] This section will describe the specific embodiments of the present application in detail. The preferred embodiments of the present application are shown in the accompanying drawings. The purpose of the accompanying drawings is to supplement the description of the text part of the specification with graphics, so that people can intuitively and vividly understand each technical feature and overall technical solution of the present application, but it cannot be understood as a limitation on the scope of protection of the present application.

[0037] In the description of this application, it should be understood that descriptions involving orientations, such as up, down, front, back, left, right, etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings. They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, they cannot be understood as limitations on this application.

[0038] In the description of this application, "several" means one or more, "many" means more than two, "greater than," "less than," and "exceed" are understood to exclude the number itself, while "above," "below," and "within" are understood to include the number itself. The terms "first" and "second" are used solely to distinguish technical features and are not to be construed as indicating or implying relative importance, or as implicitly specifying the number or order of the technical features indicated.

[0039] In the description of this application, unless otherwise clearly defined, words such as setting and connecting should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meaning of the above words in this application based on the specific content of the technical solution.

[0040] The technical solution of the present application will be further described below with reference to the embodiments and drawings.

[0041] In the embodiment of the present application, the positive direction of the X-axis in the drawings is right, and the negative direction of the X-axis is left; the positive direction of the Y-axis is front, and the negative direction of the Y-axis is back; the positive direction of the Z-axis is up, and the negative direction of the Z-axis is down.

[0042] See also Figure 1 and Figure 2 In a first aspect, an embodiment of the present application provides a bed frame 100 , which can be used to place a mattress 200 .

[0043] For example, see Figure 2 and Figure 3 The bed frame 100 includes a support assembly, a first bed board 130 and a second bed board 141. The first bed board 130 is connected to the support assembly; the second bed board 141 is rotatably connected to the support assembly. The support assembly includes a first support surface 121, which is used to support the second bed board 141 when the second bed board 141 rotates to be parallel to the first bed board 130.

[0044] When the second bed board 141 in the embodiment of the present application rotates to be parallel to the first bed board 130, the first support surface 121 of the support assembly can support the second bed board 141. At this time, the second bed board 141 can be used to extend the bed length (see Figure 4 ), or as a crib (see Figure 5 ). That is, by rotating the second bed board 141, the bed length can be adjusted to meet the different bed length requirements of different individuals; or, by rotating the second bed board 141, a baby bed can be formed, and the user does not need to purchase an additional baby bed, which can reduce economic costs. When a baby bed is not needed or the bed length is extended, the second bed board 141 can be rotated to the side close to the first bed board 130, which can reduce the occupied space and facilitate storage. The second bed board 141 can also be used as a backrest (see Figure 6 ), the tilt angle of the backrest can be adjusted by rotating the second bed board 141, thereby improving the user experience.

[0045] That is to say, the second bed board 141 in the embodiment of the present application can be switched between the backrest mode, the extended bed length mode and the crib mode, thereby realizing the multifunctionality of the bed frame 100.

[0046] Optionally, in order to make the second bed board 141 more stable in the extended bed length mode or the crib mode, a foldable support leg (not shown in the drawings) is provided on the side of the second bed board 141 away from the first bed board 130. The foldable support leg has an unfolded state and a folded state. In the backrest mode, the foldable support leg is in a folded state, close to the second bed board 141. In the extended bed length mode or the crib mode, the foldable support leg is in an unfolded state, supported on the ground.

[0047] Optionally, the first bed board 130 and the second bed board 141 are both rectangular boards, and the length of the second bed board 141 is equal to the width of the first bed board 130 . The second bed board 141 is arranged on one side of the first bed board 130 along the length direction of the first bed board 130 .

[0048] In the prior art, the height of the bed legs is not adjustable, meaning the distance between the bottom of the bed frame and the ground is not adjustable. On the one hand, if the distance between the bottom of the bed frame and the ground is too small, it is difficult for cleaning tools such as sweeping robots to reach the bottom of the bed to clean, resulting in a poor user experience. On the other hand, due to different lifestyles and heights, people have different requirements for the distance between the mattress and the ground (i.e., bed height), making it difficult for bed frames in the prior art to meet personalized height requirements.

[0049] Therefore, optionally, in some embodiments, the support assembly includes a first support member 110 and a second support member 120 connected to each other, the first bed board 130 is connected to the first support member 110 movably up and down, the second bed board 141 is rotatably connected to the second support member 120, and the first support surface 121 is arranged on the second support member 120.

[0050] See also Figure 7 By moving the first bed board 130 up or down, the distance between the first bed board 130 and the ground can be adjusted. When cleaning the bed bottom, the first bed board 130 can be moved upward to increase the distance between the first bed board 130 and the ground for easier cleaning. By moving the first bed board 130 up or down, the bed height can be adjusted to meet the different bed height requirements of different individuals.

[0051] For example, when the bed length needs to be extended, the second bed board 141 can be rotated to be parallel to the first bed board 130, and the height of the first bed board 130 can be adjusted to be the same height as the second bed board 141, so that the first bed board 130 is level with the second bed board 141, thereby extending the length of the bed.

[0052] Alternatively, in some embodiments, see Figure 8 and Figure 9The first support member 110 includes a bed leg 111, and a transmission member extending in a vertical direction is provided on the bed leg 111. The first bed board 130 is movably connected to the transmission member, and the transmission member is used to drive the first bed board 130 to move up and down.

[0053] Alternatively, in some embodiments, see Figure 8 and Figure 10 The bed leg 111 is provided with a long slot 1111 extending in the vertical direction. The transmission member includes a screw 112, which is disposed in the long slot 1111. The first bed board 130 includes a plate body 131 and a connecting block 132. The connecting block 132 is disposed on the outer periphery of the plate body 131. The connecting block 132 extends into the long slot 1111 and is sleeved on the outer periphery of the screw 112. The connecting block 132 is threadedly connected to the screw 112. Optionally, the plate body 131 and the connecting block 132 can be integrally formed.

[0054] Optionally, the bed frame 100 further includes a plurality of drive components (not shown in the drawings) equal in number to the screw rods 112, with each drive component corresponding one to each screw rod 112. The drive component is connected to one end of the screw rod 112 to rotate the screw rod 112, thereby driving the first bed board 130 to move up and down. Optionally, the drive component is a drive motor.

[0055] Exemplarily, the upper end of the screw rod 112 is rotatably connected to the bed leg 111 , and the lower end of the screw rod 112 is connected to the output shaft of the driving motor. The driving motor can be accommodated inside the bed leg 111 .

[0056] For example, the first support member 110 includes four legs 111, and four drive components are also provided, with each drive component connected to each leg 111 in a one-to-one correspondence. A connecting block 132 is provided at each of the four corners of the plate 131, each having a threaded hole 1321 formed therein. The four connecting blocks 132 respectively engage with the screws 112 in the four legs 111 through the threaded holes 1321.

[0057] Alternatively, see Figure 9 The first support member 110 may further include three connecting members 113, and the four bed legs 111 are sequentially connected by the three connecting members 113. The three connecting members 113 may form a barrier with one side opening. The barrier may be used to surround the mattress 200 on the first bed board 130 to prevent the mattress 200 from shifting.

[0058] Optionally, the connecting member 113 can be a connecting rod. Of course, the connecting member 113 can also be a connecting member 113 such as a connecting plate, which is not specifically limited here.

[0059] When the first bed board 130 moves upward to its highest position, the height of the first bed board 130 from the ground is H. To prevent the enclosure from interfering with a cleaning tool (e.g., a sweeping robot) from entering under the bed for cleaning, the bottom of the enclosure (i.e., the bottom of the connecting member 113) can optionally be at a distance greater than or equal to H from the ground.

[0060] It is understandable that after the mattress 200 is placed on the first bed board 130, the top of the mattress 200 can be higher than or equal to the height of the enclosure, so that the enclosure will not affect the user getting in and out of bed.

[0061] Optionally, in some embodiments, the bed frame 100 further includes a partition 150, which is movably connected to the first support member 110 or the second support member 120. The partition 150 can extend vertically from the first support surface 121 when the second bed board 141 is rotated to be parallel to the first bed board 130 to separate the first bed board 130 and the second bed board 141.

[0062] Optionally, the separator 150 may be a separator plate. Of course, the separator 150 may also be other separators such as a separator guardrail, which is not specifically limited herein.

[0063] Alternatively, in some embodiments, see Figure 11 and Figure 12 The second support member 120 is connected to one side of the first support member 110, and the partition 150 is connected to the side of the second support member 120 away from the first support member 110 so as to be movable up and down. The second bed board 141 is provided with a through groove 1411, and the through groove 1411 is used for the partition 150 to pass through and extend out of the second support member 120.

[0064] Exemplarily, the second support member 120 can be a bed screen base, the second support member 120 can be connected to the side of the first support member 110 having an opening, the second bed board 141 is connected to the upper end of the second support member 120 through the first electric shaft 122, and the first support surface 121 is the top surface of the second support member 120.

[0065] Alternatively, in some embodiments, see Figure 11 and Figure 13 A first guide portion 124 is provided on the side of the second support member 120 away from the first support member 110, and a second guide portion 151 is provided on the partition 150. The second guide portion 151 is connected to the first guide portion 124 to guide the partition 150 to move up and down.

[0066] For example, the first guide portion 124 may be a guide groove extending in a vertical direction, and the second guide portion 151 may be a slide shaft extending in a vertical direction. Optionally, a motorized slider (not shown in the drawings) is disposed within the guide groove and is fixedly connected to the slide shaft. By driving the motorized slider up and down along the guide groove, the partition 150 can be driven up and down via the slide shaft. Optionally, when the partition 150 is moved downward to its lowest position, the top of the partition 150 can be flush with the top of the second support member 120.

[0067] Optionally, two first guide portions 124 are provided at intervals on a side of the second support member 120 facing away from the first support member 110 , and two second guide portions 151 are provided at intervals on the partition member 150 .

[0068] It can be understood that the number of the first guide parts 121 and the number of the second guide parts 151 are the same and correspond one to one. The specific number of the first guide parts 121 and the second guide parts 151 can be set according to actual needs and is not specifically limited here.

[0069] Alternatively, in some embodiments, see Figure 11 and Figure 14 The bed frame 100 further includes a guardrail 160 , which is connected to an end of the second bed board 141 away from the partition 150 , and the guardrail 160 is foldable in a direction perpendicular to the second bed board 141 .

[0070] Optionally, in some embodiments, the guardrail 160 includes at least one horizontal bar 161 and at least one vertical bar 162, one end of the vertical bar 162 is rotatably connected to the second bed board 141, and the other end is rotatably connected to the horizontal bar 161, and the vertical bar 162 is used to rotate toward the second bed board 141 to drive the horizontal bar 161 to approach and fold onto the second bed board 141.

[0071] For example, the guardrail 160 includes two crossbars 161 and a plurality of vertical bars 162, wherein one crossbar 161 is fixedly connected to the second bed board 141, and a plurality of vertical bars 162 are spaced apart between the two crossbars 161, and the ends of the vertical bars 162 are rotatably connected to the two crossbars 161. It is understood that the specific number of vertical bars 162 can be set according to actual needs and is not specifically limited here.

[0072] Alternatively, see Figure 14The two horizontal bars 161 are each provided with a groove 1611 on the opposite side. The ends of the vertical bar 162 extend into the grooves 1611 of the two horizontal bars 161 and are connected to the two horizontal bars 161 via a second electric shaft 163. The guardrail 160 can be deployed or folded by rotating the second electric shaft 163. When the guardrail 160 is folded, the opposite sides of the two horizontal bars 161 are in contact, and the two grooves 1611 are connected to form a receiving cavity, which can accommodate the second electric shaft 163.

[0073] See also Figure 5 or Figure 11 When the second bed board 141 is rotated to be parallel to the first bed board 130 to form a crib, the partition 150 can be moved upward so that the partition 150 extends out of the second support member 120, and the guardrail 160 can be unfolded to form a baffle on both sides of the second bed board 141, thereby improving the safety of the crib.

[0074] Alternatively, in some embodiments, see Figure 15 The bed frame 100 further includes a soft bag 142 , which is detachably connected to the second bed board 141 .

[0075] It can be understood that when the second bed board 141 is used to lean on the body, the soft bag 142 can be installed on the second bed board 141 to increase the softness; and the soft bag is detachably connected to the second bed board 141, so the user can adjust the position of the soft bag 142 according to their needs to further improve the user experience.

[0076] Optionally, the soft bag 142 is connected to the second bed board 141 via a Velcro. Of course, the soft bag 142 can also be connected to the second bed board 141 via a buckle or other detachable manner, which is not specifically limited here.

[0077] Alternatively, see Figure 4 , the soft bag 142 includes a horizontal portion 1421 and a raised portion 1422 connected to each other. Figure 15 , the lengths of the horizontal portion 1421 and the raised portion 1422 are both equal to the width of the first bed board 130. Optionally, the cross-section of the raised portion 1422 is arc-shaped. Of course, the cross-sectional shape of the raised portion 1422 can also be wavy or other shapes, and there is no specific limitation here. Optionally, the horizontal portion 1421 is arranged close to the first bed board 130, and the raised portion 1422 is connected to the end of the horizontal portion 1421 away from the first bed board 130. Optionally, the horizontal portion 1421 can be integrally formed with the raised portion 1422.

[0078] For example, the soft pad 142 can be installed at the first preset position of the second bed board 141 so that the end of the horizontal portion 1421 away from the raised portion 1422 abuts against the mattress 200, thereby preventing a gap between the soft pad 142 and the mattress 200. Of course, the user can also adjust the installation position of the soft pad 142 according to their needs to adjust the position of the raised portion 1422, thereby improving comfort.

[0079] It is understandable that when the second bed board 141 is used to extend the bed length, the user can choose to remove or not remove the soft pad 142 according to actual needs. For example, when removing the soft pad 142, the height of the first bed board 130 can be adjusted to be equal to the height of the second bed board 141, and then the extended mattress 200 can be placed on the first bed board 130 and the second bed board 141 to form an extended bed; when the soft pad 142 is not removed, the height of the first bed board 130 can be adjusted so that the top surface of the mattress 200 is flush with the top surface of the horizontal part 1421 of the soft pad 142, and the soft pad 142 is installed in the second preset position of the second bed board 141 so that the end of the horizontal part 1421 away from the protrusion 1422 abuts against the mattress 200 (see Figure 4 ), thereby forming an extended bed. Optionally, the raised portion 1422 of the soft bag 142 can also be used as a pillow.

[0080] Optionally, the bed frame 100 further includes a controller and a control panel 123 , the control panel 123 is communicatively connected to the controller, and the drive motor, the electric slider, the first electric rotating shaft 122 , and the second electric rotating shaft 163 are all electrically connected to the controller.

[0081] The control panel 123 can control the opening and closing of the drive motor and its direction of rotation through the controller, thereby controlling the height of the first bed board 130; it can control the rotation of the first electric shaft 122, thereby controlling the angle between the second bed board 141 and the first bed board 130; it can control the opening and closing of the electric slider and its moving direction, thereby controlling the up and down movement of the partition 150; it can control the rotation of the second electric shaft 163, thereby controlling the folding and unfolding of the guardrail 160.

[0082] Alternatively, see Figure 15The control panel 123 is provided on the right outer side of the second support member 120 for user operation. Optionally, a first upward button and a second downward button are provided on the control panel 123. The first button is used to move the first bed board 130 upward, and the second button is used to move the first bed board 130 downward. Optionally, a third forward button and a fourth backward button are also provided on the control panel 123. The third button is used to rotate the second bed board 141 forward, and the fourth button is used to rotate the second bed board 141 backward. Optionally, a fifth upward button and a sixth downward button are also provided on the control panel 123. The fifth button is used to move the partition 150 upward, and the sixth button is used to move the partition 150 downward. Optionally, a seventh button and an eighth button are also provided on the control panel 123. The seventh button is used to unfold the guardrail 160, and the eighth button is used to fold the guardrail 160.

[0083] Optionally, the second support member 120 is further provided with a power socket on the same side as the control panel 123 , and the power socket is electrically connected to the control panel 123 , and the power socket is used to connect to a power source to provide power to the control panel 123 .

[0084] Other structures and operations of the bed frame 100 according to the embodiment of the first aspect of the present application are known to ordinary technicians in this field and will not be described in detail here.
