Description

Technical Field

[0001] The present application relates to the technical field of furniture equipment, and in particular to an electric lift bed. Background Art

[0002] Electric lift beds are mostly made of steel or steel-wood. They are popular among urban users because of their lifting function, adjustable bed height, and the ability to utilize the variable space under the bed. Related electric lift beds, such as the electric lift bed with publication number CN221204754U previously applied for by the applicant in this case, include a bed frame and lift legs connected to the frame. Specifically, a pair of lift legs are mounted at the head of the frame, and a pair of lift legs are mounted at the tail of the frame. Each pair of lift legs is connected to a transmission rod that is connected to the screw-nut assembly within each leg, and a drive motor that is connected to the transmission rod. The drive motor is generally located near one of the legs. In addition, the electric lift bed is also equipped with a controller and a hand controller. The controller is generally mounted at the bottom of the frame and is electrically connected to the drive motors at the head and tail of the frame via wiring. The hand controller is also electrically connected to the controller via wiring.

[0003] The wiring of the electric lift bed of the related technology is generally routed along the four sides of the bed frame, that is, the wiring of the controller and the drive motors at the head and tail of the bed frame is passed through the crossbeam on the rear side of the bed frame along the length of the bed frame, but in order to facilitate the connection between the controller and the drive motor, the wiring heads of the two are set on the outside; the hand controller is generally installed on the crossbeam on the front side of the bed frame, and the wiring of the hand controller and the controller must pass through a part of the crossbeam on the front side of the bed frame and the head or tail of the bed frame; therefore, it is inevitable that there will be more wiring harnesses and wiring harness connectors concentrated at the head and / or tail of the bed frame, and the head and tail of the bed frame are both provided with a transmission rod and a drive motor; in order to prevent the wiring harness, wiring harness connector, transmission rod and drive motor from being exposed from the bed frame, either a shielding plate that is suitable for the size of the bed frame is installed at the bottom of the bed frame to shield the wiring harness, wiring harness connector and transmission rod; or only the transmission rod is shielded by a baffle, and the wiring harness and wiring harness connector are hidden inside the bed frame after connection.

[0004] The above-mentioned related art electric lift bed has the following defects during actual use: the entire shielding plate is connected to the bottom of the bed frame to shield the wiring harness, wiring harness connector, transmission rod and drive motor. When the entire circuit of the electric lift bed is inspected, the entire shielding plate needs to be removed, which is very inconvenient and laborious; and the method of hiding the wiring harness and wiring harness connector inside the crossbeam of the bed frame makes it easy for the wiring harness and wiring harness connector to be exposed when the electric lift bed is in use, and the plugging and unplugging operation of the wiring harness connector is also very inconvenient when the circuit is inspected.

[0037] The present application will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0038] See also Figures 1 to 8As shown; an embodiment of the present application discloses an electric lift bed, whose structure includes a bed frame 1, a fence 2 connected to the bed frame 1 and two groups of lifting components 3 respectively connected to the head and tail of the bed frame 1. The bed frame 1 is a steel bed frame 1 or a steel-wood bed frame 1, which includes two hollow bed beams 100 arranged along the length direction and a slat frame component 101 connected between the two bed beams 100; each group of lifting components 3 includes two lifting bed legs 300 and a screw nut component in the two lifting bed legs 300; the electric lift bed includes at least one drive motor 302, which is arranged on the lower side of the bed frame 1, and the drive motor 302 is driven and connected to the screw nut component for driving the lifting bed legs 300 to rise and fall; it is not difficult to understand that the electric lift bed also includes a hand controller 304 and a controller 303, the controller 303 is connected next to the lifting bed legs 300 of one group of lifting components 3, and the hand controller 304 is installed on the bed beam 100 on the side of the bed frame 1 close to the user.

[0039] Specifically in this embodiment, there are two drive motors 302, that is, an electric lifting bed driven by dual drive motors; the two drive motors 302 are respectively arranged corresponding to the two groups of lifting components 3, and each drive motor is connected to the two screw nut assemblies of the two lifting bed legs 300 in the corresponding lifting component 3 through the transmission rod 301; therefore, the transmission rod 301 and the drive motor 302 are respectively connected to the head and tail of the bed frame 1.

[0040] It is not difficult to understand that the power cord of the controller 303 of the electric lifting bed of this embodiment is connected to the indoor power cord along one of the lifting bed legs 300 downward, and the controller 303 is connected to the head of the bed frame 1; the controller 303 is electrically connected to the drive motors 302 on the two sets of lifting components 3 through a wiring harness. Specifically, the drive motors 302 on one set of lifting components 3 are connected to the controller 303 through a wiring harness, and the wiring harness is arranged at the head of the bed frame 1, and the drive motors 302 on the other set of lifting components 3 are connected to the controller 303 through the inner hole of the bed beam 100 through the wiring harness, and the wiring harness is at least partially arranged at the tail of the bed frame 1; the wiring harness of the hand controller 304 passes through part of the bed beam 100 and is electrically connected to the controller 303 at the head of the bed, and the wiring is also arranged on the bed frame. 1; in addition, other accessories of the electric lifting bed are also electrically connected to the controller 303, such as the table lamp under the bed frame 1, the personnel detection unit on the bed frame 1, etc., which also need to be electrically connected to the controller 303 with a wiring harness, and the wiring harness and the wiring harness connector are all arranged at the head or tail of the bed frame 1; therefore, in addition to the drive motor 302 and the transmission rod 301 of the lifting component 3, the controller 303 and various wiring harnesses are also installed at the head or tail of the bed frame 1, so that the user can see the transmission rod 301 of the lifting component 3 and the drive motor 302, controller 303 and various wiring harnesses on the lifting component 3 from the bottom of the bed frame 1, that is, the transmission rod 301, drive motor 302, controller 303 and various wiring harnesses of the lifting component 3 are exposed to the bed frame 1, posing a great safety hazard.

[0041] In order to avoid the transmission rod 301, the driving motor 302, the controller 303 and the wiring harness at the head or tail of the bed frame 1 from being exposed, and also for the convenience of wiring maintenance, see Figure 3 、 Figure 4 and Figure 5 As shown, the electric lift bed also includes at least one motor cover 5 and at least one wire shield 4. The motor cover 5 is connected to the edge of the bed frame, that is, the motor cover 5 is connected to the head or tail of the bed frame 1 and covers the drive motor 302 corresponding to the lifting assembly 3; the wire shield 4 is connected to the edge of the bed frame, that is, the wire shield 4 is set at the head or tail of the bed frame 1 and is set corresponding to the motor cover 5; the wire shield 4 is used to shield the transmission rod 301, drive motor 302 of the lifting assembly 3 and the wiring harness arranged at the head or tail of the bed frame 1, preventing the transmission rod 301, drive motor 302, wiring harness and wiring harness connector of the lifting assembly 3 from being exposed, thereby improving the safety of the electric lift bed; in addition, when the entire circuit of the electric lift bed is under maintenance, it is only necessary to remove the wire shield 4 to inspect the wiring harness and plug and unplug the wiring harness connector, making the circuit maintenance operation simple and convenient. Moreover, after the circuit maintenance is completed, it is only necessary to connect the wire shield 4 to the bed frame 1, which is very simple and labor-saving to install.

[0042] For example, see Figure 4 、 Figure 5 、 Figure 6 and Figure 7 As shown, there are two motor covers 5, one connected to the head and one to the tail of the bed frame 1; and two wire shields 4, one set at the head and one to the tail of the bed frame 1. The motor cover 5 is a wooden board, laid between the two bed beams 100 of the bed frame 1, with its top flush with the ribs 101 of the bed frame 1. The motor cover 5 is above the lifting assembly 3 and vertically covers the transmission rod 301 of the lifting assembly 3 and the drive motor 302 of the lifting assembly 3. The wire shield 4 is set below the bed frame 1, and the length direction of the wire shield 4 is consistent with the width direction of the bed frame 1.

[0043] Further in this embodiment, see Figure 4 、 Figure 6 and Figure 7 As shown, the fence 2 includes a headboard assembly 200 connected to the head of the bed frame 1 and a footboard assembly 201 connected to the tail of the bed frame 1. The headboard assembly 200 and the footboard assembly 201 are used to cover the head and tail of the bed frame 1 respectively; and the fence 2 also includes a front rail assembly located on the side of the bed frame 1 close to the user and a rear rail assembly located on the side of the bed frame 1 away from the user.

[0044] In this embodiment, the wire shielding plate 4 is a thin plate. Figure 6 、 Figure 7 and Figure 8 As shown, the wire shielding plate 4 has a first connecting portion 400 connected to the motor cover plate 5 and a second connecting portion 401 arranged opposite to the first connecting portion 400, a shielding portion 402 is provided between the first connecting portion 400 and the second connecting portion 401 of the wire shielding plate 4, a first pivoting portion 404 extending along the length direction of the wire shielding plate 4 is provided between the shielding portion 402 and the first connecting portion 400, and a second pivoting portion 405 extending along the length direction of the wire shielding plate 4 is provided between the shielding portion 402 and the second connecting portion 401; the first connecting portion 400, the shielding portion 402 and the second connecting portion 401 are arranged around the part of the lifting assembly, that is, the outside of the transmission rod 301, the drive motor 302 and the wiring harness. In other words, the wire shielding plate 4 is composed of three parts of plates, namely the first connecting part 400, the shielding part 402 and the second connecting part 401, wherein the first connecting part 400 can rotate around the first pivot part 404 relative to the shielding part 402, and the second connecting part 401 can rotate around the second pivot part 405 relative to the shielding part 402, so as to facilitate the installation of the wire shielding plate 4. During installation, the first connecting part 400 and the second connecting part 401 can be rotated to a suitable angle relative to the shielding part 402 and respectively connected to the motor cover 5 and the fence 2 or the bottom of the bed frame 1; similarly, when the product is packaged before leaving the factory, the wire shielding plate 4 can be rotated and folded to reduce the packaging volume.

[0045] Furthermore, in this embodiment, the first connecting portion 400 of the wire shielding plate 4 is connected to the top of the motor cover 5, the shielding portion 402 of the wire shielding plate 4 extends downward along the height direction of the bed frame 1, and the second connecting portion 401 extends horizontally toward the head or tail direction of the bed frame 1 to the bottom of the fence 2, and is connected to the bottom of the fence 2 by screws, so that the wire shielding plate 4, the motor cover 5 and the fence 2 enclose a shielding space that shields the transmission rod 301, the drive motor 302, the wiring harness and the wiring harness connector.

[0046] Specifically, to facilitate installation and removal of the wire shield 4 for line maintenance, the first connecting portion 400 of the wire shield 4 passes through the bed frame 1 from bottom to top and is detachably connected to the top of the motor cover 5. The second connecting portion 401 of the wire shield 4 at the head of the bed frame 1 is screwed to the bottom of the headboard assembly 200; and the second connecting portion 401 of the wire shield 4 at the tail of the bed frame 1 is screwed to the bottom of the footboard assembly 201.

[0047] For example, the first connecting portion 400 is connected to the top of the motor cover 5 via Velcro. That is, a Velcro is attached to the top of the motor cover 5. The first connecting portion 400 of the wire shield 4 passes through the bed frame 1 from bottom to top, and the first connecting portion 400 is horizontally placed on the top of the motor cover 5 and connected to the Velcro on the motor cover 5. The second connecting portion 401 is then flipped horizontally around the second pivot portion 405. At this time, the outer end of the second connecting portion 401 is located at the bottom of the fence 2. The second connecting portion 401 is then fixed to the bottom of the fence 2 using screws or other fasteners. When removing the wire shield 4, the first connecting portion 400 can be disconnected from the Velcro on the motor cover 5 to open the wire shield 4 and expose the wiring harness. This facilitates maintenance personnel. After the maintenance is completed, the first connecting portion 400 of the wire shield 4 can be replaced, that is, the first connecting portion 400 of the wire shield 4 is once again bonded to the Velcro on the motor cover 5.

[0048] Furthermore, in this embodiment, the wire shielding plate 4 is made of felt; it can not only be bonded to the Velcro on the motor cover 5, but also be convenient for shaping or bending, and the first pivot portion 404 and the second pivot portion 405 on the wire shielding plate 4 can be indentations or grooves on the wire shielding plate 4, and their thickness is less than the thickness of the wire shielding plate 4, which facilitates the rotation of the first connection portion 400 and the second connection portion 401.

[0049] In other embodiments, the wire shielding plate 4 can also have other structures, such as the wire shielding plate including a cloth outer cover and a base plate mounted inside the outer cover, and the base plate including a first plate corresponding to the first connecting portion, a second plate corresponding to the shielding portion, and a third plate corresponding to the second connecting portion, a first stitching portion is sewn on the outer cover between the first plate and the second plate, a second stitching portion is sewn on the outer cover between the second plate and the third plate, the first stitching portion forms a first pivot portion, and the second stitching portion forms a second pivot portion. This arrangement can also facilitate bonding with the Velcro on the motor cover, and facilitates the rotational installation of the first and second connecting portions of the wire shielding plate.

[0050] In order to make the wire shield 4 and the bed frame 1 more tightly combined, see Figure 7 and Figure 8 As shown, in this embodiment, the first connection portion 400 of the wire shield 4 is provided with a clearance groove 403 that avoids the longitudinal rods of the bed frame 1, and the clearance groove 403 at least partially extends to the shielding portion 402. Therefore, after the wire shield 4 is installed, the first connection portion 400 of the wire shield 4 is parallel to the top surface of the bed frame 1, the shielding portion 402 is parallel to the height direction of the bed frame 1, and the second connection portion 401 of the wire shield 4 is parallel to the first connection portion 400. This not only better shields the transmission rod 301, the drive motor 302, the wiring harness and the controller 303, but also makes the bottom of the bed frame 1 more neat and aesthetically pleasing.

[0051] In some embodiments, the shielding plate 4 can be removed from the first connecting portion 400, that is, the shielding plate 4 only has a shielding portion 402 connected to the motor cover 5 and a second connecting portion 401 connected to the shielding portion 402, and a second pivoting portion 405 extending along the length of the shielding plate 402 is provided between the shielding portion 402 and the second connecting portion 401. The shielding portion 402 and the second connecting portion 401 are arranged around the outside of the lifting assembly 3, that is, the transmission rod, the drive motor 302, and the wiring harness. Specifically, when connecting, the shielding portion 402 of the shielding plate 4 is connected to the side of the motor cover 5, and the second connecting portion 401 rotates around the second pivoting portion 405 relative to the shielding portion 402 to the bottom of the fence 2 or bed frame 1 and connects to the bottom of the fence or bed frame 1. Similarly, in this embodiment, the shielding portion 402 of the shielding plate 4 is connected to the side of the motor cover 5 by Velcro, and the second connecting portion 401 is connected to the bottom of the fence 2 or bed frame 1 by screws.

[0052] In some embodiments, the electric lift bed can also be an electric lift bed driven by a single drive motor, that is, there is only one drive motor, which is installed in the middle position of the bed frame in the length direction, and the drive motor is connected to the screw nut assembly in the four lift legs through multiple transmission rods; specifically, the two bed beams of the bed frame are respectively connected to the drive rods that are simultaneously driven and connected to the screw nut assembly in the lift legs of the two lifting assemblies, and an intermediate drive rod is connected between the two drive rods, which is driven and connected to the drive motor. The drive motor drives the intermediate drive rod to rotate, and the two sets of lifting assemblies are driven and raised through the two drive rods in the two bed beams. The electric lift bed driven by a single drive motor has a motor cover and a wire shield, and the motor cover is set in the middle of the bed frame and covers the drive motor, that is, the motor cover is connected to the center of the bed frame, and the wire shield is also connected to the center of the bed frame and corresponds to the position of the motor cover.

[0053] In some embodiments, the electric lift bed can also be an electric lift bed with four drive motors, that is, there are four drive motors, and each drive motor is driven and connected to the screw nut assembly in the corresponding lift bed leg; that is, there is no transmission rod between the two lift bed legs of the electric lift bed, but there are still more wiring harnesses gathered between the two lift bed legs of each group of lifting assemblies. Therefore, the motor cover and wire shielding plate of the electric lift bed are both set to two, and the installation method of the two motor cover plates and the two wire shielding plates is consistent with the installation method of the above-mentioned electric lift bed with dual drive motors, and no repetitive description is made in this embodiment.
