Description

Technical Field

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

[0002] Electric lift beds are mostly made of steel or steel-wood structures. They are popular among urban users because of their lifting function, ability to adjust the height of the bed and use of the variable space under the bed. The electric lift bed of the related technology, such as the electric lift bed with announcement number CN217161559U, announcement number CN218542118U and announcement number CN216358434U previously applied by the applicant of this case, has a structure including a bed frame and four lift legs connected to the bed frame. Specifically, a pair of lift legs are installed at the head of the bed frame, and a pair of lift legs are installed at the tail of the bed frame. Two pull rods are connected between each pair of lift legs, and a longitudinal rod extending along the length direction of the bed frame is connected to the side of the bed frame away from the user, and the two ends of the longitudinal rod are respectively connected to the two pairs of lift legs; the bed frame is arranged in a rectangular shape, which includes two longitudinal beams extending along the length direction of the bed frame, and the two ends of the two longitudinal beams are respectively connected to transverse beams, the two longitudinal beams and the two transverse beams are connected end to end in a rectangular shape, and a slat frame is connected between the two longitudinal beams; a fence is connected around the bed frame, and the fence is connected to the longitudinal beam and transverse beam of the bed frame by screws. After the bed frame of the electric lift bed of this structure is assembled, connecting grooves or connecting parts for connecting the tops of four lift bed legs are formed at the four corners of the bed frame. Therefore, when assembling this type of electric lift bed, it is necessary to first connect the four lift bed legs through pull rods and longitudinal rods, and then assemble the bed frame so that the bed frame is installed as a whole on the tops of the four lift bed legs, and finally complete the installation of the fence or guardrail.

[0003] The above-mentioned related art electric lift bed has the following defects in the actual installation process: First, the connection part on the bed frame for connecting the top of the lift bed legs is formed after the bed frame is assembled; therefore, after the four lift bed legs are connected by the pull rod and the longitudinal rod, the bed frame needs to be assembled on the ground, that is, first, two longitudinal bed beams and two transverse bed beams are spliced ​​into a rectangular frame, and then the rectangular frame is hoisted to the top of the four lift bed legs, and the connection parts at the four corners of the rectangular frame are respectively aligned with the top of the four lift bed legs to complete the assembly; however, due to the inevitable installation error or clearance fit accuracy error when the rectangular frame is assembled and the four lift bed legs are connected, the connection parts at the four corners of the bed frame cannot be accurately aligned with the top of the lift bed legs, so the installer needs to loosen the connection screws of the rectangular frame to calibrate the installation accuracy of the rectangular frame or recalibrate the installation accuracy of the four lift bed legs, resulting in troublesome, laborious, and time-consuming installation. Furthermore, the rectangular frame of the bed frame is heavy, and the operation is laborious when hoisting or lifting it to the top of the lift bed legs. In addition, after the bed frame and the lifting bed legs are assembled, the headboard assembly, footboard assembly, front panel and rear panel of the fence need to be surrounded and installed on the rectangular frame of the bed frame in sequence, which requires many installation steps and is troublesome to operate.

During installation, the top wall of the slot of the plug-in seat is against the top of the lifting bed leg, and there is a plane contact between the two, so it is easy to judge the horizontality of the rear block assembly or the front block assembly during installation, further improving the assembly accuracy.

[0019] Furthermore, the electric lift bed of the present application is a modular installation structure, and the rear baffle assembly, front baffle assembly, head assembly and foot assembly of the bed body are all assembled before the product leaves the factory, so when the electric lift bed is installed, the installation process is simple; in particular, after the rear baffle assembly, front baffle assembly, head assembly and foot assembly of the bed body are assembled, the frame of the bed frame of the electric lift bed is connected, avoiding the need to install the fence of the bed frame after the bed frame is installed.

[0044] The present application is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0045] See also Figures 1 to 10 As shown; an embodiment of the present application discloses an electric lifting bed, whose structure includes a bed body 2 and a lifting component 1, the lifting component 1 is connected to the bottom of the bed body 2, and the lifting of the lifting component 1 can drive the bed body 2 to adjust the height, and when the lifting component 1 descends to the lowest position, there is still a certain activity space between the bottom of the bed body 2 and the ground, and the height of the activity space depends on the height of the lifting component 1 when it descends to the lowest position.

[0046] In this embodiment, the lifting assembly 1 includes two lifting frames 100 and a longitudinal rod 106 connecting the two lifting frames 100. Each lifting frame 100 includes a transmission rod 103, a driving motor 104 for driving the transmission rod 103 to rotate, and two lifting bed legs: a first lifting bed leg 101 and a second lifting bed leg 102. The two ends of the transmission rod 103 are respectively connected to the screw nut assemblies in the two lifting bed legs; that is, the driving motor 104 drives the first lifting bed leg 101 and the second lifting bed leg 102 to rise and fall synchronously through the transmission rod 103.

[0047] For example, there are four drive motors, each of which is driven and connected to the corresponding screw nut assembly in the lifting bed leg; there are two drive motors, and the drive motors are driven and connected to the two screw nut assemblies in the corresponding lifting assembly through a transmission rod; there is one drive motor, and the drive motor is driven and connected to the screw nut assemblies in the four lifting bed legs through a transmission rod.

[0048] For example, see Figure 1 and Figure 2 As shown, the lifting assembly 1 includes four lifting bed legs, and the lifting bed legs are combined in pairs to form two lifting frames 100 respectively located at the head and the tail of the bed body 2. In each lifting frame 100, at least one pull rod 105 is connected between the two lifting bed legs, that is, between the first lifting bed leg 101 and the second lifting bed leg 102. A lead screw nut assembly is connected inside each lifting bed leg to drive the lifting bed leg to axially extend and retract, which is a technical means of the existing mature technology and will not be described in detail in this embodiment.

[0049] Further, in this embodiment, the upper end of each lifting bed leg is connected to a gear box that is transmission-connected to the lead screw nut assembly; the two ends of the transmission rod 103 of each lifting frame 100 are respectively transmission-connected to the gear boxes in the two lifting frames 100. The driving motor 104 is connected to a position close to one of the lifting bed legs and is transmission-connected to the transmission rod 103, and is used to drive the transmission rod 103 to rotate, so that the first lifting bed leg 101 and the second lifting bed leg 102 are synchronously lifted and lowered. Moreover, in this embodiment, at least one longitudinal rod 106 is provided between the two lifting frames 100, and the longitudinal rod 106 is arranged on the side of the bed body 2 away from the user or on the side close to the wall, and the two ends of the longitudinal rod 106 are respectively connected to the two first lifting bed legs 101 of the two lifting frames 100, so that the two lifting frames 100 and the longitudinal rod 106 form a whole to form a lifting assembly 1.

[0050] It is not difficult to understand that the electric lift bed also includes a hand controller 107 and a controller 108. The controller 108 is connected to the side of the lift bed leg of one of the lift frames 100, and the hand controller 107 is installed on the side wall of the bed body 2 close to the user. The power cord of the controller 108 of the electric lift bed is connected to the indoor power cord along one of the lift bed legs downward, and the controller 108 is connected to the head of the bed body 2; the controller 108 is electrically connected to the drive motors 104 of the two lift frames 100 through a wiring harness.

[0051] In this embodiment, the bed body 2 of the electric lifting bed includes a rear block assembly 200, a front block assembly 201, a head assembly 202 and a foot assembly 203, and the rear block assembly 200, the front block assembly 201, the head assembly 202 and the foot assembly 203 are sequentially surrounded to form a frame and a fence of the bed body 2, in order to facilitate the connection between the bed body 2 and the lifting assembly 1; see Figure 1 , Figure 3 , Figure 4 , Figure 5 and Figure 6As shown, both ends of the rear block component 200 and both ends of the front block component 201 are respectively connected with sockets 204 that match and plug into the top ends of the lifting bed legs, the sockets 204 at both ends of the rear block component 200 are respectively plugged and fixed with the top ends of the two first lifting bed legs 101 of the lifting assembly 1, and the sockets 204 at both ends of the front block component 201 are respectively plugged and fixed with the top ends of the two second lifting bed legs 102 of the lifting assembly 1; the headboard component 202 is arranged at the head of the bed body 2 and is respectively connected to the ends of the rear block component 200 and the front block component 201, and the footboard component 203 is arranged at the tail of the bed body 2 and is respectively connected to the ends of the rear block component 200 and the front block component 201.

[0052] For example, see Figure 4 and Figure 5 As shown, the inner side walls of the two ends of the rear block assembly 200 are respectively connected with a socket 204, the socket 204 is formed by bending a metal plate, and each socket 204 has a slot 205 with an opening 206 facing downward and for accommodating the top of the lifting bed leg. Because the lifting bed leg is a rectangular parallelepiped, the slot 205 is set as a square slot 205 adapted to the top of the lifting bed leg, and the socket 204 is connected with a fastener connected to the top of the lifting bed leg when the socket 204 is plugged into the top of the lifting bed leg, and the fastener is also a connecting screw. The rear block assembly 200 is located on the back of the bed body 2, and the two sockets 204 of the rear block assembly 200 are plugged into the top of the two first lifting bed legs 101 of the lifting assembly 1 from top to bottom, and are fixedly connected to the top of the two first lifting bed legs 101 through connecting screws. Similarly, the sockets 204 at both ends of the front block assembly 201 are the same as the sockets 204 at both ends of the rear block assembly 200. After being plugged into the top ends of the two second lifting bed legs 102, they are fixedly connected to the top ends of the two second lifting bed legs 102 through connecting screws.

[0053] Further in this embodiment, see Figure 4 and Figure 5 As shown, each socket 204 is provided with an open opening 207 connected with the slot 205 and the opening 206 on one side close to the center of the bed body 2. In other words, the socket 204 is provided with an open side on one side close to the center of the bed body 2, which is used to avoid the transmission rod 103 installed on the top of the lifting bed leg on the one hand, and on the other hand, when the socket 204 is plugged with the top of the lifting bed leg, not only can the socket 204 be plugged with the top of the lifting bed leg from the bottom opening 206 from top to bottom, but also can be plugged with the top of the lifting bed leg from the side opening 207 from outside to inside, so that the connection of the rear stop assembly 200 and the front stop assembly 201 is more convenient and simple.

[0054] In this embodiment, when the electric lifting bed is installed, the lifting bed legs are connected in pairs to form two lifting frames 100, and then the two lifting frames 100 are connected through the longitudinal rod 106; because both ends of the rear block assembly 200 and the front block assembly 201 of the bed body 2 are connected with the sockets 204 that match the top of the lifting bed legs, when the bed body 2 is installed, the sockets 204 at both ends of the rear block assembly 200 are respectively plugged and fixed with the top of the two first lifting bed legs 101 of the two lifting brackets, and then the sockets 204 at both ends of the front block assembly 201 are respectively plugged and fixed with the top of the two second lifting bed legs 102 of the two lifting brackets, and finally the head assembly 202 and the foot assembly 203 are connected and covered on the ends of the rear block assembly 200 and the front block assembly 201, so that the frame of the bed body 2 is assembled, and the fence of the electric lifting bed is also basically assembled. Therefore, the electric lifting bed is simple and convenient to install, saving time and effort.

[0055] The rear block assembly 200 and the front block assembly 201 are sequentially connected to the top of the lifting bed leg of the lifting assembly 1, so that the entire bed body 2 is not hoisted as a whole to connect to the top of the lifting bed leg of the lifting assembly 1 after the entire bed body 2 is assembled. Therefore, the installation is labor-saving and simple, and the defect of being difficult to accurately align with the top of the lifting bed leg of the lifting assembly 1 due to the assembly accuracy error of the entire bed body 2 is avoided; furthermore, the rear block assembly 200 and the front block assembly 201 are first plugged and then fixed with the top of the lifting bed leg through the plug-in seat 204, so when installing the rear block assembly 200 or the front block assembly 201, it is only necessary to plug the slot 205 of the plug-in seat 204 into the top of the lifting bed leg, without manual lifting or hoisting, and the installation is very labor-saving. Moreover, during installation, the inner top wall of the slot 205 of the plug-in seat 204 is against the top of the lifting bed leg, and there is a plane contact between the two, so it is easy to judge the horizontality of the rear block assembly 200 or the front block assembly 201 during installation, further improving the assembly accuracy.

[0056] Furthermore, the electric lift bed of the present application is a modular installation structure. The rear block assembly 200, the front block assembly 201, the head assembly 202 and the foot assembly 203 of the bed body 2 are all assembled when the product leaves the factory. Therefore, when installing the electric lift bed, the installation process is simple; in particular, after the rear block assembly 200, the front block assembly 201, the head assembly 202 and the foot assembly 203 of the bed body 2 are assembled, the frame of the bed frame of the electric lift bed is connected to avoid installing the fence of the bed frame after the bed frame is installed. Therefore, the electric lift bed is not only simple in structure, but also fast in installation.

[0057] In this embodiment, the bed body 2 further includes a slatted frame 109, which is disposed between the rear guard assembly 200 and the front guard assembly 201; the rear guard assembly 200 is an integral part, that is, it has been assembled into a whole when the electric lifting bed leaves the factory. Figure 4As shown, the rear guard assembly 200 includes a first bed beam 208 and a rear enclosure 209 connected to the top of the first bed beam 208, and the two ends of the first bed beam 208 are connected to the sockets 204, and the inner wall of the first bed beam 208 is connected to the first support part 210 for connecting the slat frame 109 of the bed body 2; wherein, the rear enclosure 209 is also the rear part of the fence of the bed body 2; the first support part 210 is a plurality of protruding support rods along the inner wall of the first bed beam 208, and the top of the support rod can be connected or supported by one side of the slat frame 109.

[0058] In other embodiments, the rear stop assembly 200 can also be split into two independent parts, namely the first bed beam 208 and the rear stop 209. After the installer connects the first bed beam 208 to the top of the two first lifting bed legs 101 of the lifting assembly 1, the rear stop 209 is connected to the top of the first bed beam 208 by connecting screws.

[0059] Further in this embodiment, see Figure 5 As shown, the front block assembly 201 includes a second bed beam 211 and a front enclosure 212 connected to the top of the second bed beam 211. The two ends of the second bed beam 211 are connected to the socket 204. The inner wall of the second bed beam 211 is connected to a second support portion 213 corresponding to the first support portion 210 and connected to the slat frame 109 of the bed body 2. The second support portion 213 is a plurality of outwardly protruding support rods along the inner wall of the second bed beam 211. The top of the support rod can be supported or connected to the other side of the slat frame 109. The front block assembly 201 is a split type, and can also be connected as one when leaving the factory.

[0060] It is easy to understand that the front guard assembly 201 is provided with an opening 206 for the user to enter the bed body 2, so the length of the front enclosure 212 is smaller than the length of the second bed beam 211. The opening 206 can be set at the left or right end of the front guard assembly 201 according to the needs of the user. In addition, the first bed beam 208 and the second bed beam 211 are both hollow structures, and the inside is used for wiring harness routing. For example, the first bed beam 208 can be used for wiring of the controller 108 and the drive motor 104, and the second bed beam 211 can be used for wiring of the controller 108 and the hand controller 107.

[0061] Furthermore, in this embodiment, the plug socket 204 is at least partially protruded on the outer side of the end surface of the rear block assembly 200 and the front block assembly 201, and the side of the head assembly 202 and the foot assembly 203 close to the bed body 2 is respectively provided with a groove 214 for the protruding part of the plug socket 204 to be embedded. In this way, after the head assembly 202 and the foot assembly 203 are assembled, not only can the head assembly 202 and the foot assembly 203 cover the ends of the rear block assembly 200 and the front block assembly 201, but also the connection between the head assembly 202 and the foot assembly 203 and the rear block assembly 200 and the front block assembly 201 is more firmly and the structure is more compact.

[0062] For example, see Figure 3 and Figure 6 As shown, the plug sockets 204 at both ends of the rear block assembly 200 and the front block assembly 201 extend outward from the rear block assembly 200 and the front block assembly 201 respectively, and two grooves 214 are provided on both sides of the inner wall of the head assembly 202. After the head assembly 202 is connected to the ends of the rear block assembly 200 and the front block assembly 201, the protruding parts of the plug socket 204 are embedded in the two grooves 214. The cooperation between the protruding parts of the plug socket 204 and the grooves 214 of the head assembly 202 prevents the head assembly 202 from moving horizontally, thereby making the head assembly 202 more firmly and stably connected to the ends of the rear block assembly 200 and the front block assembly 201. In addition, the structure of the foot assembly 203 is the same as that of the head assembly 202, and this embodiment will not be described repeatedly.

[0063] It is not difficult to understand that the power cord of the controller 108 of the electric lifting bed is connected to the indoor power cord along one of the lifting bed legs downward, and the controller 108 is connected to the head of the bed body 2; the controller 108 is electrically connected to the drive motors 104 of the two lifting frames 100 through a wiring harness. Specifically, the drive motor 104 of one lifting frame 100 is connected to the controller 108 through a wiring harness, and the wiring harness is arranged at the head of the bed body 2, and the drive motor 104 of the other lifting frame 100 is connected to the controller 108 through the inner hole of the first bed beam 208 through the wiring harness, and the wiring harness is at least partially arranged at the tail of the bed body 2; the wiring of the hand controller 107 passes through part of the second bed beam 211 and is electrically connected to the controller 108 located at the head of the bed, and the wiring is also arranged at The head of the bed 2; plus other accessories of the electric lifting bed are also electrically connected to the controller 108, such as the table lamp under the bed 2, the personnel detection unit on the bed 2, etc., which also need to be electrically connected to the controller 108 with a wiring harness, and the wiring harness and the wiring harness connector are all arranged at the head or tail of the bed 2; therefore, in addition to the transmission rod 103 and the drive motor 104 of the lifting frame 100, the controller 108 and various line harnesses are also installed at the head or tail of the bed 2, so that the user can see the transmission rod 103 and the drive motor 104 of the lifting frame 100, the controller 108 and various line harnesses under the bed 2, that is, the transmission rod 103 and the drive motor 104 of the lifting frame 100, the controller 108 and various line harnesses are exposed, posing a safety hazard.

[0064] In this embodiment, in order to prevent the transmission rod 103 and the drive motor 104, the controller 108 and the wiring harnesses at the head or tail of the bed 2 from being exposed, and also for the convenience of wiring maintenance, see Figure 7 , Figure 8 and Fig. 9As shown, the electric lift bed also includes two wire shielding plates 4 corresponding to the two lifting frames 100 respectively, and a motor cover plate 3 connected to the bed body 2 above the two lifting frames 100 and correspondingly covering the drive motor 104. Each wire shielding plate 4 has a first connection portion 400 connected to the motor cover plate 3 and a second connection portion 401 connected to the bottom of the head assembly 202 or the foot assembly 203, which is used to shield the transmission rod 103 of the lifting bracket, the drive motor 104, and the wire harness arranged at the head or tail of the bed body 2. The wire shielding plate 4 can shield the transmission rod 103, the drive motor 104 of the lifting frame 100, and the wire harness arranged at the head or tail of the bed body 2, so as to avoid the transmission rod 103, the drive motor 104, the wire harness and the wire harness connector from being exposed, thereby improving the safety of the electric lift bed; in addition, when the entire line of the electric lift bed is inspected, the wire harness can be inspected and the wire harness connector can be plugged in and out by simply removing the wire shielding plate 4, so that the line inspection operation is simple and convenient. Furthermore, after the line maintenance is completed, it is only necessary to connect the first connection portion 400 and the second connection portion 401 of the wire shielding plate 4 to the motor cover plate 3 and the bottom of the bed body 2 respectively, so the installation is very simple and labor-saving.

[0065] For example, see Fig. 9 As shown, there are two motor cover plates 3, which are respectively connected to the head and the tail of the bed body 2; there are two wire shielding plates 4, which are respectively arranged at the head and the tail of the bed body 2. The motor cover 3 is a wooden plate, which is laid between the two bed beams of the bed body 2 and the top is flush with the slat frame 109 of the bed body 2. The motor cover 3 is above the lifting frame 100 and covers the transmission rod 103 and the driving motor 104 of the lifting frame 100 in the vertical direction. The length direction of the wire shielding plate 4 is consistent with the width direction of the bed body 2, and the wire shielding plate 4 is a thin plate with a relatively thin thickness. The first connecting portion 400 of the wire shielding plate 4 is connected to the top of the motor cover 3. The first connecting portion 400 of the wire shielding plate 4 extends downward and extends toward the head or tail direction of the bed body 2 to the bottom of the headstock assembly 202 or the footstock assembly 203, and is connected to the bottom of the headstock assembly 202 or the footstock assembly 203 by screws, so that the wire shielding plate 4, the motor cover 3 and the headstock assembly 202 or the wire shielding plate 4, the motor cover 3 and the footstock assembly 203 enclose a shielding space to shield the transmission rod 103, the driving motor 104, the wiring harness and the wiring harness connector.

[0066] Further in this embodiment, see Figure 6 , Figure 7 and Figure 8As shown, a shielding portion 402 is provided between the first connection portion 400 and the second connection portion 401 of the wire shielding plate 4, a first pivot portion 404 extending along the length direction of the wire shielding plate 4 is provided between the shielding portion 402 and the first connection portion 400, and a second pivot portion 405 extending along the length direction of the wire shielding plate 4 is provided between the shielding portion 402 and the second connection portion 401; the first connection portion 400, the shielding portion 402 and the second connection portion 401 are arranged around the outside of the transmission rod 103, the driving motor 104 and the wiring harness of the lifting stand 100; the first connection portion 400 is detachably connected to the top of the motor cover 3 by Velcro. In other words, the wire shielding plate 4 is composed of three parts, 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. This facilitates 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 or position relative to the shielding part 402 to connect with the motor cover 3 and the bottom of the bed 2; 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.

[0067] When disassembling the wire shielding plate 4, it is only necessary to disconnect the first connecting part 400 from the Velcro on the motor cover 3 to open the wire shielding plate 4 and expose the wiring harness. This is convenient for maintenance personnel to inspect and repair. After the inspection is completed, the first connecting part 400 of the wire shielding plate 4 can be covered again, that is, the first connecting part 400 of the wire shielding plate 4 can be bonded to the Velcro on the motor cover 3 again.

[0068] Furthermore, in the present embodiment, the wire shielding plate 4 is made of felt; it can not only be bonded to the Velcro on the motor cover 3, but also is 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 that of the wire shielding plate 4, so as to facilitate the rotation of the first connection portion 400 and the second connection portion 401.

[0069] In order to make the wire shielding plate 4 and the bed body 2 more closely combined, see Figure 7 , Figure 8 and Fig.10 As shown, the first connection part 400 of the wire shielding plate 4 is provided with a clearance groove 403 for avoiding the longitudinal rod of the bed body 2, and the clearance groove 403 at least partially extends to the shielding part 402. Therefore, after the wire shielding plate 4 is installed, the first connection part 400 of the wire shielding plate 4 is parallel to the top surface of the bed body 2, the shielding part 402 is parallel to the height direction of the bed body 2, and the second connection part 401 of the wire shielding plate 4 is parallel to the first connection part 400, which can not only better shield the transmission rod 103, the drive motor 104, the wiring harness and the controller 108, but also make the bottom of the bed body 2 more neat and beautiful.

[0070] See also Figure 11 to Figure 14 As shown; another embodiment of the present application discloses an installation method of an electric lift bed, which is used to install the electric lift bed of the above embodiment, comprising the following steps: S1: connecting four lift bed legs into two lift frames 100, and connecting a longitudinal rod 106 between the two lift frames 100, so that the two lift frames 100 and the longitudinal rod 106 are connected as a whole to form a lift assembly 1. Specifically, see Fig.11 As shown, the four lifting bed legs are connected in pairs to form two lifting frames 100, that is, two pull rods 105 are connected between the first lifting bed leg 101 and the second lifting bed leg 102 of each lifting frame 100, and two parallel longitudinal rods 106 are connected between the two first lifting bed legs 101 of the two lifting frames 100. Thus, the four lifting bed legs, the pull rods 105 and the longitudinal rods 106 are connected as a whole to form a lifting assembly 1. S2: The sockets 204 at both ends of the rear stop assembly 200 are respectively plugged into the top ends of the two first lifting bed legs 101 of the two lifting frames 100, and the sockets 204 are fixedly connected to the top ends of the first lifting bed legs 101, see also Fig.12 The connection state shown; the sockets 204 at both ends of the front block assembly 201 are respectively plugged into the top ends of the two second lifting legs 102 of the two lifting frames 100, and the sockets 204 are fixedly connected to the top ends of the second lifting legs 102. In this step S2, the rear block assembly 200 is located on the back of the bed body 2, and the two sockets 204 of the rear block assembly 200 are plugged into the top ends of the two first lifting legs 101 of the lifting assembly 1 from top to bottom, and are fixedly connected to the top ends of the two first lifting legs 101 by connecting screws. Similarly, see Fig.13 As shown, the sockets 204 at both ends of the front block assembly 201 are the same as the sockets 204 at both ends of the rear block assembly 200. After being plugged into the top ends of the two second lifting bed legs 102, they are fixedly connected to the top ends of the two second lifting bed legs 102 through connecting screws. S3: Place the head assembly 202 on the head of the bed body 2, cover and connect to the ends of the first end of the rear block assembly 200 and the front block assembly 201 through screws; and place the foot assembly 203 on the tail of the bed body 2, cover and connect to the ends of the second end of the rear block assembly 200 and the front block assembly 201 through screws, see together Fig.14 Displays the connection status.

[0071] After step S2 of the above-mentioned method for installing the electric lift bed is completed, the hand controller 107 and the wiring between the hand controller 107 and the controller 108 need to be installed on the second bed beam 211 of the front stop assembly 201. After the hand controller 107 and the wiring between the hand controller 107 and the controller 108 are connected, the operation of step S3 is performed.

[0072] It is not difficult to understand that since the installation is affected by factors such as the installation environment and the skills of the installer, when connecting each component with screws, such as connecting the head assembly 202 and the foot assembly 203, the screws are generally pre-tightened first. After all the screws are pre-tightened and the joints of the components are aligned, all the screws are tightened.

[0073] After the above step S3 is completed, the armrests of the bed body 2 can be installed, that is, two armrests are connected at one end of the front block component 201 close to the rear of the bed body 2 and one end of the rear bed component 203 close to the front block component 201, and finally the bed body 2 row frame 109 is installed, the lines are plugged in, and the power is tested, and finally the motor cover 3, the wire shielding plate 4 and other accessories of the electric lift bed are connected.
