[0029] The present invention is further described in detail below in conjunction with the accompanying drawings.

[0030] Figure 1 is a schematic diagram of folding a folding electric bed according to an embodiment of the present invention, Figure 2FIG. 2 is a top view of a folding electric bed according to an embodiment of the present invention. Figure 1 and Figure 2 As shown, the folding electric bed provided by the present invention includes: an upper bed body 1, a lower bed body 2 and a split fixing part 3; wherein, the two ends of the split fixing part 3 are respectively fixedly connected to the outer walls of the upper bed body 1 and the lower bed body 2 on the same side, and the upper bed body 1 is foldable relative to the lower bed body 2 at the split fixing part 3; the split fixing part 3 includes: a first fixing member 31 and a second fixing member 32; wherein, the first fixing member 31 and the second fixing member 32 are detachably fixedly connected, the first fixing member 31 is arranged on the outer wall of the upper bed body 1, and the second fixing member 32 is arranged on the outer wall of the lower bed body 2.

[0031] UPS is one of the most commonly used express delivery companies in the United States. The charging standards of this express delivery company are particularly strict. When the package size and weight meet the requirements, it is particularly economical and has a great competitive advantage in terminal sales. The UPS standard is that the outer package size = length + (width + height) × 2 < 3940 mm, and the gross weight of the whole bed is less than 68KG. To meet this standard, the electric bed of 1524 mm × 2032 mm must be made into a folding structure.

[0032] When the first fixing member 31 and the second fixing member 32 are not connected, the upper bed body 1 and the lower bed body 2 can be stacked on each other, and the upper bed body 1 and the lower bed body 2 can also be folded together by a pivot connection at the junction of the two. A connecting member can also be added, and the two ends of the connecting member are respectively connected to the pivots of the upper bed body 1 and the lower bed body 2, and the length of the connecting member itself is used to provide freedom for the folding of the bed body. The upper bed body 1 and the lower bed body 2 are folded after relative rotation with the pivot connection 4 between the two as the rotation axis, so that the upper bed body 1 and the lower bed body 2 are fully folded, the length of the bed body in the folding direction is shortened to about 50% of the original length, and the upper bed body 1 and the lower bed body 2 are fully folded in half, the thickness of the bed after folding is controlled, and the packaging size requirements of UPS are met.

[0033] When unfolded, the split fixing part 3 strengthens the connection strength between the upper bed body 1 and the lower bed body 2 through the connection between the first fixing part 31 and the second fixing part 32, preventing the junction from collapsing when the user uses it, which is safer and more reliable; the first fixing part 31 and the second fixing part 32 can be fixed by the cooperation of bolts and nuts, and the split fixing part 3 can also be fixedly connected by installing the bed feet, which not only strengthens the connection strength between the upper bed body 1 and the lower bed body 2, but also provides more reliable support for the middle part of the bed body, thereby improving the stability of the entire bed body when in use; when folding, it is only necessary to separate the first fixing part 31 and the second fixing part 32 to fold, which is simple and quick.

[0034] In addition, through the foldable connection of the upper bed body 1 and the lower bed body 2 and the cooperation of the split fixing part 3, the bed body can be folded and packaged after the main body assembly is completed in the factory, which can reduce the packaging size of the bed body and facilitate packaging and transportation. When in use, it is only necessary to unfold the folded bed body and fix the relative position between the first fixing part 31 and the second fixing part 32 to limit the folding between the upper bed body 1 and the lower bed body 2. The installation is simple and labor-saving.

[0035] Further, Figure 3 FIG. 1 is a first top view of the folding electric bed according to an embodiment of the present invention. Figure 2 and Figure 3 As shown, the upper bed body 1 includes: a first load-bearing part 11, a first flipping mechanism 12, a first sliding mechanism 13, a first limiting mechanism 14 and an upper frame 15, and the lower bed body 2 includes: a second load-bearing part 21, a second flipping mechanism 22, a second sliding mechanism 23, a second limiting mechanism 24 and a lower frame 25; wherein, the first load-bearing part 11 is arranged at the top of the upper frame 15, the first flipping mechanism 12 and the first pulley mechanism are both located between the first load-bearing part 11 and the upper frame 15, the two ends of the first flipping mechanism 12 are respectively pivotally connected to the head 101 of the first load-bearing part 11 and the upper frame 15, the first pulley mechanism is respectively fixedly connected to the first load-bearing part 11 and the tail 201 of the upper frame 15 so that the first load-bearing part 11 can slide relative to the upper frame 15, and the first limiting mechanism 14 is The two ends are pivotally connected to the first load-bearing part 11 and the head 101 of the upper frame 15 respectively; the second load-bearing part 21 is arranged at the top of the lower frame 25, the second flipping mechanism 22 and the second pulley mechanism are both located between the second load-bearing part 21 and the lower frame 25, the two ends of the second flipping mechanism 22 are pivotally connected to the second load-bearing part 21 and the head 101 of the lower frame 25 respectively, the second pulley mechanism is fixedly connected to the second load-bearing part 21 and the lower frame 25 respectively so that the second load-bearing part 21 can slide relative to the lower frame 25, the two ends of the second limiting mechanism 24 are pivotally connected to the tail 201 of the first load-bearing part 11 and the second sliding mechanism 23 respectively; the first sliding mechanism 13 and the second sliding mechanism 23 are pivotally connected at the junction of the upper bed body 1 and the lower bed body 2.

[0036] When the first flipping mechanism 12 is working, it pushes the first load-bearing part 11 to flip upward in whole or in part relative to the upper frame 15. The flipping of the first load-bearing part 11 moves with the first limiting mechanism 14 as a radius. The length of the first limiting mechanism 14 and the connection positions of its two ends are designed according to the flipping angle required. With the cooperation of the first sliding mechanism 13, the first limiting mechanism 14 pulls the first load-bearing part 11 to move in the direction of the head 101 of the upper frame 15. When the first sliding mechanism 13 moves toward the head 101 of the bed, it also drives the second sliding mechanism 23 pivotally connected to the first sliding mechanism 13 to move toward the head 101 of the bed. The second load-bearing part 21 moves toward the head 101 of the bed following the second sliding mechanism 23, so that the first load-bearing part 11 and the second load-bearing part 21 still maintain a basically unchanged relative distance from the head 101 of the upper frame 15 during the flipping process, thereby realizing the function of the head 101 of the first load-bearing part 11 against the wall, avoiding the head 101 of the bed from moving closer to the tail 201 after flipping, and providing the user with a better visual distance.

[0037] When the second flipping mechanism 22 is working, it pushes the second load-bearing part 21 to flip upward in whole or in part relative to the lower frame 25. The flipping of the second load-bearing part 21 takes the length of the second limiting mechanism 24 as a radius. The length of the second limiting mechanism 24 can be designed according to actual needs, which limits the motion trajectory and height of the flipping of the second load-bearing part 21. When the first sliding mechanism 13 pulls the second sliding mechanism 23 to translate, the second limiting mechanism 24 also translates at any time, maintaining the restriction on the motion trajectory and height of the flipping of the second load-bearing part 21, which is conducive to maintaining the flipping shape of the second load-bearing part 21 and giving the user a more comfortable sleeping position.

[0038] Furthermore, if Figure 2 As shown, the first load-bearing part 11 includes: a first load-bearing component 111 and a second load-bearing component 112, and the second load-bearing part 21 includes: a third load-bearing component 211, a fourth load-bearing component 212 and a fifth load-bearing component 213; the first load-bearing component 111 and the second load-bearing component 112 are pivotally connected at the junction; the third load-bearing component 211, the fourth load-bearing component 212 and the fifth load-bearing component 213 are pivotally connected at the junction in sequence.

[0039] The first load-bearing component 111 and the second load-bearing component 112 are pivotally connected, and the third load-bearing component 211, the fourth load-bearing component 212 and the fifth load-bearing component 213 are pivotally connected in sequence at the junction. By adjusting the connection relationship between the first flipping mechanism 12 and the second flipping mechanism 22 and different load-bearing components, a variety of bed surface deformations can be achieved to meet different needs.

[0040] Preferably, the first flipping mechanism 12 pushes the first load-bearing component 111 to flip upward relative to the upper frame 15, and the second flipping mechanism 22 pushes the fourth load-bearing component 212 to flip upward relative to the lower frame 25. When the fourth load-bearing component 212 flips, it drives the fifth load-bearing component 213 to flip together. The first weighing component is mainly used to support the head 101 and back of the human body, the second load-bearing component 112 and the third load-bearing component 211 are mainly used to support the arms, and the fourth load-bearing component 212 and the fifth load-bearing component 213 are used to support the legs of the human body and cooperate with the bending of the legs of the human body, giving the user a more comfortable experience.

[0041] Further, Figure 4 FIG. 2 is a second bottom view of the folding electric bed according to the embodiment of the present invention. Figure 3 and Figure 4 As shown, the upper frame 15 includes: a first support member 151, a second support member 152, a third support member 153, a fourth support member 154 and a fifth support member 155, and the lower frame 25 includes: a sixth support member 251, a seventh support member 252, an eighth support member 253, a ninth support member 254 and a tenth support member 255; wherein, the first support member 151 is parallel to the second support member 152, the third support member 153, the fourth support member 154 and the fifth support member 155 are parallel to each other, the two ends of the first support member 151 and the second support member 152 are respectively vertically connected to the two ends of the third support member 153 and the fourth support member 154, and the third support member 153, the fourth support member 154 and the fifth support member 155 are parallel to each other, and the two ends of the first support member 151 and the second support member 152 are respectively vertically connected to the two ends of the third support member 153 and the fourth support member 154, and the third support member 153, the fourth support member 154 and the fifth support member 155 are parallel to each other. The two ends of the fifth support member 155 are respectively vertically connected to the first support member 151 and the second support member 152 and are located below the first load-bearing component 111; the sixth support member 251 is parallel to the seventh support member 252, the eighth support member 253, the ninth support member 254 and the tenth support member 255 are parallel to each other, the two ends of the sixth support member 251 and the seventh support member 252 are respectively vertically connected to the two ends of the eighth support member 253 and the ninth support member 254, and the two ends of the tenth support member 255 are respectively parallel and vertically connected to the sixth support member 251 and the seventh support member 252 and are located below the fourth load-bearing component 212.

[0042] The first to tenth support members 255 are preferably long strips of metal parts. If the strength is sufficient, hollow metal tubes can also be used. Of course, other plastic parts that meet the strength requirements can also be used to reduce the weight of the bed, facilitate transportation, and save transportation costs.

[0043] Furthermore, if Figure 3As shown, the first sliding mechanism 13 includes: a first track, a first pulley group 131 and a first pulley seat 132; wherein the first track is arranged on the inner side walls of the first support member 151 and the second support member 152, the first pulley group 131 is pivotally connected to the first pulley seat 132, the first pulley seat 132 is fixedly connected to the second support assembly, and the first pulley group 131 can slide in the first track; the second sliding mechanism 23 includes: a second track, a second pulley group 231, a second pulley seat 232, a third track 233, a third pulley group and a third pulley seat 234; wherein the second track is arranged on the inner side walls of the sixth support member 251 and the seventh support member 252, The second pulley group 231 is pivotally connected to the second pulley seat 232, the second pulley seat 232 is fixedly connected to the third support assembly, and the second pulley group 231 can slide in the second track; the third track is vertically fixedly connected to the middle part of the ninth support member 254 and extends toward the direction of the tenth support assembly, the top surface of the third track is flush with the top surface of the lower frame 25, the third pulley group is pivotally connected to the third pulley seat 234, the third pulley seat 234 is fixedly connected to the fifth support assembly, and the third pulley group can slide on the second track; the first pulley seat 132 and the second pulley seat 232 are pivotally connected at the junction of the upper frame 15 and the lower frame 25.

[0044] The lengths of the first track, the second track, and the third track 233 are set according to the required sliding distance to match each deformation and limit sliding. The first track, the first pulley block 131, and the first pulley seat 132 cooperate so that the first load-bearing component 111 and the second load-bearing component 112 slide on the upper frame 15, and the second track, the second pulley block 231, the second pulley seat 232, the third track 233, the third pulley block, and the third pulley seat 234 cooperate in groups so that the third load-bearing component 211, the fourth load-bearing component 212, and the fifth load-bearing component 213 slide on the lower frame 25. In particular, if the third track 233, the third pulley block, and the third pulley are installed below the top surface of the lower frame 25, when the tail 201 of the fifth load-bearing component 213 exceeds the edge of the lower frame 25, the fifth load-bearing component 213 may interfere with the lower frame 25 during movement, which is not conducive to the realization of the wall-supporting function of the bed body. The wall-leaning function of the bed is achieved through the cooperation of multiple sliding mechanisms, and the translation height of the fifth load-bearing part is made higher than the lower frame 25 by adding a third track, so that the load-bearing components beyond the edge of the lower frame 25 can also be smoothly translated, ensuring the realization of the wall-leaning function.

[0045] Furthermore, if Figure 3 and Figure 4As shown, the second sliding mechanism 23 also includes: a fourth track, a fourth pulley group 235 and a fourth pulley seat 236; wherein, the fourth track is arranged on the inner wall of the sixth support member 251 and the seventh support member 252, the fourth pulley group 235 is pivotally connected to the fourth pulley seat 236, the fourth pulley seat 236 is fixedly connected to the head 101 of the fifth support assembly, and the fourth pulley group 235 can slide in the fourth track; the two ends of the second limiting mechanism 24 are pivotally connected to the fourth pulley seat 236 and the fifth load-bearing assembly 213 respectively.

[0046] When the second flipping mechanism 22 pushes the fourth load-bearing component 212 to flip upward relative to the lower frame 25 starting from the tail 201, the fifth load-bearing part not only follows the flipping, but also, with the cooperation of the second limiting mechanism 24, the fifth load-bearing part can be lifted as a whole, which can provide the user with better foot support and allow the user to further relax; when the fifth load-bearing component 213 moves toward the head 101, with the cooperation of the fourth track, the fourth pulley set 235 and the fourth pulley seat 236, the second limiting mechanism 24 moves horizontally together, and will not limit the horizontal movement of the fifth load-bearing component 213, thereby ensuring that the load-bearing part of the bed body is close to the head 101.

[0047] Furthermore, if Figure 3 and Figure 4 As shown, the two ends of the first flipping mechanism 12 are respectively connected to the head 101 of the first load-bearing component 111 and the middle vertical pivot of the fifth support member 155, and the second flipping mechanism 22 includes: a driving motor 221 and a scissors-type bracket; wherein, one end of the driving motor 221 is connected to the middle vertical pivot of the seventh support member 252; the scissors-type bracket includes: a first support frame 222 and a second support frame 223; the two ends of the first support frame 222 are respectively pivotally connected to the tail 201 of the fourth load-bearing component 212 and the other end of the driving motor 221, and the two ends of the second support frame 223 are respectively pivotally connected to the middle of the tenth support member 255 and the middle of the first support frame 222.

[0048] When the driving motor 221 is working, the driving motor 221 pushes the scissor-type bracket to move closer to the direction of the tenth support member 255, but is restricted by the first support frame 222 and the second support frame 223, and can only use the pivot connection point of the first support frame 222 and the second support frame 223 as the rotation axis to push the angle between the first support frame 222 and the second support frame 223 to continuously expand, thereby pushing the fourth load-bearing component 212 to flip upward relative to the lower frame 25 and driving the fifth load-bearing component 213 to flip. The scissor-type bracket realizes the flipping of the fourth support component and the fifth support component through the horizontal push of the motor, occupies less space in the vertical direction, and is conducive to reducing the thickness of the bed.

[0049] Further, Figure 5 FIG. 1 is a schematic diagram of a folding state of a folding electric bed according to an embodiment of the present invention. Figure 5 As shown, the thickness at the center of the pivot connection 4 between the fourth load-bearing component 212 and the fifth load-bearing component 213 is smaller than its outer thickness, and the outer thickness of the pivot connection 4 between the fourth load-bearing component 212 and the fifth load-bearing component 213 is smaller than the thickness of the fourth load-bearing component 212 and the fifth load-bearing component 213.

[0050] When the fourth load-bearing component 212 and the fifth load-bearing component 213 are turned upward, if the thickness of the pivot joint 4 is the same as the thickness of the fourth load-bearing component 212 or the fifth load-bearing component 213, the highest point of the pivot joint 4 is lower than the transition arc of the fourth load-bearing component 212 and the fifth load-bearing component 213, and will not be embedded in the mattress, but the highest point of the pivot joint 4 exceeds the transition radius of the fourth load-bearing component 212 and the fifth load-bearing component 213, and the top of the pivot joint 4 will be embedded in the mattress, causing wear and scratches on the mattress. By controlling the thickness of the pivot joint 4 between the fourth load-bearing component 212 and the fifth load-bearing component 213 and reducing the transition radius of the fourth load-bearing component 212 and the fifth load-bearing component 213, wear and scratches on the mattress can be avoided as much as possible.

[0051] Furthermore, if Figure 5 As shown, the fourth load-bearing component 212 also includes: a reinforcing rod 2121, an anti-foolproof component 2122 and a buffer component 2123; wherein, the reinforcing rod 2121 is arranged on the third load-bearing component 211, the anti-foolproof component 2122 and the buffer component 2123 are both arranged on the reinforcing rod 2121, the anti-foolproof component 2122 is located directly above the driving motor 221 and extends in the direction of the driving motor 221, and the buffer component 2123 is located directly above the eighth support component 253 and extends to the top of the eighth support component 253.

[0052] The anti-mistake piece 2122 extends in the direction of the installation position of the drive motor 221, and combined with the structure of the drive motor 221, limits the installation position of the drive motor 221. If the installer installs it upside down, it cannot be successfully installed. The installer is reminded to adjust the placement of the drive motor 221, which is helpful to prevent the motor from interfering with the frame due to the motor being installed upside down.

[0053] The buffer member 2123 extends the top of the eighth support member 253 to form a support, thereby increasing the supporting strength of the third load-bearing component 211, and also strengthening the support of the fourth load-bearing component 212 and the fifth load-bearing component 213, thereby stabilizing the load-bearing surface composed of the third load-bearing component 211, the fourth load-bearing component 212 and the fifth load-bearing component 213; at the same time, when the flipping is completed and restored to a flat state, the third load-bearing component 211 will have a certain impact when it descends to the vicinity of the eighth support member 253. The buffer member 2123 releases part of the impact in advance, thereby preventing all load-bearing parts from impacting the flipping mechanism at the same time, thereby extending the service life of the bed.

[0054] Furthermore, if Figure 4 As shown, the first load-bearing component 111 also includes: a multi-function socket 1111 ; wherein the multi-function socket 1111 is arranged on the lower surface of the first load-bearing component 111 .

[0055] The multifunctional socket 1111 can be a common power socket, a double-hole USB socket, etc. The multifunctional socket 1111 rises and falls synchronously with the first load-bearing component 111. The charging cable will not be tightened or not long enough due to the rising of the bed board, which is convenient for users to use.
