[0003] However, the defects of the existing electric beds are also very obvious. No matter how delicate the electric cylinder and its linkage mechanism are set, the cylinder body bracket always needs to be fixed at a certain angular position, that is, inclined, occupying packaging space and increasing transportation costs. Summary of the Invention

[0004] The purpose of the present invention is to provide a foldable electric bed to solve the problems in the prior art.

[0005] The purpose of the present invention is achieved as follows: A foldable electric bed includes:

[0008] A flipping drive device for driving the movable board to flip upward, the flipping drive device includes an electric cylinder and a cylinder bracket, and both ends of the electric cylinder are respectively rotatably connected to one end of the cylinder bracket and the movable board;

[0009] A locking hinge seat and a locking mechanism installed on the locking hinge seat are further provided, the locking hinge seat is fixedly connected to the lower surface of the fixed board and / or the bed frame, and the other end of the cylinder bracket is rotatably connected to the locking hinge seat up and down;

[0010] In the use state, the cylinder bracket is locked at the use angular position by the locking mechanism, the cylinder bracket is inclined in the direction of the electric cylinder with the locking hinge seat as the reference, and the rotation connection point between the cylinder bracket and the electric cylinder is at the lowest position and set as the support base of the electric cylinder.

[0011] Further, in the packaging state, after the cylinder bracket is unlocked by the locking mechanism, it folds in the direction opposite to the electric cylinder and is stored in the bed frame together with the electric cylinder.

[0012] Further, the cylinder bracket is provided with a storage groove, and in the packaging state, part of the electric cylinder is received in the storage groove.

[0013] Further, the cylinder bracket is provided with a locking groove that is locked and cooperated with the locking mechanism in the use state.

[0014] Furthermore, the locking groove is located close to the rotation connection point between the cylinder bracket and the locking hinge seat.

[0015] Furthermore, the locking mechanism comprises:

[0016] A movable lock seat, the movable lock seat is rotatably connected to the locking hinge seat;

[0017] A locking pin is fixedly inserted into the movable lock seat and is inserted into the locking groove when locking the cylinder bracket.

[0018] Furthermore, the locking mechanism also includes a spring, two ends of which are respectively connected to the movable lock seat and the locking hinge seat, and the expansion and contraction direction of the spring conforms to the direction in which the lock pin is inserted into the lock slot.

[0019] Furthermore, in the packaged state, the bed board assembly and the bed frame are parallel to each other to form an overall substantially flat structure.

[0023] 2. The cylinder bracket can be quickly locked and unlocked, so that it is convenient to quickly switch between the packaging state and the use state. When switching to the use state, the elastic force of the spring drives the lock pin to quickly insert into the lock slot of the cylinder bracket, so that the cylinder bracket can be quickly locked at a preset angle position. When switching to the packaging state, just rotate the locking hinge in the opposite direction to make the lock pin disengage from the lock slot, and the cylinder bracket can be rotated and folded;

[0024] 3. There are two optional packaging modes. The electric bed can be flattened or folded in half, making the use of packaging space more flexible, thus flexibly adapting to packaging containers or other boxes of different specifications. BRIEF DESCRIPTION OF THE DRAWINGS

[0036] Next, the present invention will be further described in conjunction with the attached Figures 1-11 drawings and specific embodiments.

[0037] As Figure 1 , 3 , as shown in 6, a foldable electric bed includes:

[0038] A horizontally placed bed frame 2 in the shape of a rectangular frame, with several bed legs 10 detachably arranged thereon;

[0039] A bed board group 1, erected on the bed frame 2, which is divided into a fixed board 1b and a movable board. The fixed board 1b is fixedly connected to the bed frame 2, and the movable board is rotatably connected to the bed frame 2;

[0040] A flipping drive device for driving the movable board to flip upward. The flipping drive device includes an electric cylinder 4 and a cylinder bracket 4. The two ends of the electric cylinder 4 are respectively rotatably connected to one end of the cylinder bracket 4 and the movable board.

[0041] Among them, in this embodiment, as Figure 1 , 5As shown in FIGS. 6, the fixed plate 1b mainly supports the buttocks. The movable plate is provided as a back plate 1a, a thigh plate 1d, and a calf plate 1c, which support the back, thigh, and calf respectively. There are two sets of flipping drive devices, which are respectively arranged on the front and rear sides of the electric bed. The electric cylinder 4 of one set of flipping drive devices is used to lift and lower the back plate 1a, and the bracket on the bottom surface of the back plate 1a is rotatably connected to the bed frame 2. The electric cylinder 4 of the other set of flipping drive devices is used to lift and lower the thigh plate 1d. The thigh plate 1d and the calf plate 1c are rotatably connected. Support connecting rods 9 are rotatably connected to both the left and right sides of the bed frame 2, and the two support connecting rods 9 are also respectively rotatably connected to the left and right sides of the calf plate 1c. When the thigh plate 1d is lifted, the calf plate 1c and the support connecting rods 9 rotate together, and the thigh plate 1d, the calf plate 1c, and the support connecting rods 9 form a quadrilateral linkage mechanism.

[0042] As shown in Figure 5 、 7 、8, and 9, the electric bed is further provided with a locking hinge seat 5 and a locking mechanism installed on the locking hinge seat 5. The locking hinge seat 5 is fixedly connected to the lower surface of the fixed plate 1b and / or the bed frame 2. The other end of the cylinder bracket 4 is rotatably connected to the locking hinge seat 5 up and down. The cylinder bracket 4 is in the structure of a strip-shaped seat.

[0043] In the use state, the cylinder bracket 4 is locked at the use angle position by the locking mechanism. The cylinder bracket 4 is inclined in the direction of the electric cylinder 3 with the locking hinge seat 5 as the reference. The rotation connection point between the cylinder bracket 4 and the electric cylinder 3 is at the lowest position and is set as the support base of the electric cylinder 3. Combining Figure 4 、 5 shown, the cylinder bracket 4 and the electric cylinder 3 always present an irregular V-shaped structure with the opening facing upward.

[0044] After the above-mentioned cylinder bracket 4 is unlocked by the locking mechanism, it folds in the direction opposite to the electric cylinder 3 and is stored in the bed frame 2 together with the electric cylinder 3, so as to facilitate the selection of a longer specification electric cylinder 3. The above-mentioned cylinder bracket 4 is provided with a storage groove 4b. In the packaging state, part of the electric cylinder 3 is received in the storage groove 4b, so as to further save the packaging space, so that there is no structural interference between the electric cylinder 3 and the cylinder bracket 4 during folding. And after folding, the electric cylinder 3 and the cylinder bracket 4 are parallel to each other.

[0045] In the packaging state, as shown in Figure 2 , the bed plate group 1 and the bed frame 2 are parallel to each other to form a structure that is generally flat as a whole, that is, a flat structure.

[0046] As another packaging state, as shown in Figure 10 、 11As shown in the figure, the bed frame 2 is divided into a first frame part 2a and a second frame part 2b that are rotatably connected to each other. The bed board group 1 is divided into two plates corresponding to the first frame part 2a and the second frame part 2b respectively. One part of the fixing plate 1b and the back board 1a form one plate, and the other part of the fixing plate 1b, the thigh board 1d, and the calf board 1c form the other plate. In the packaging state, the first frame part 2a and the second frame part 2b rotate relative to each other until the two plates of the bed board group 1 are parallel to each other, so that the electric bed can be folded in half as a whole.

[0047] In both of the above two packaging states, all the bed legs 10 need to be removed.

[0048] As an optimized solution for quickly locking and unlocking the cylinder bracket 4, the above cylinder bracket 4 is provided with a lock groove 4a that is locked and cooperated with the locking mechanism in the use state, and the position of the lock groove 4a is close to the rotation connection point of the cylinder bracket 4 and the locking hinge seat 5.

[0049] The above locking mechanism includes:

[0050] A movable lock seat 6, and the movable lock seat 6 is rotatably connected to the locking hinge seat 5;

[0051] A lock pin 8, the lock pin 8 is fixedly inserted into the movable lock seat 6 and is inserted into the lock groove 4a when locking the cylinder bracket 4;

[0052] A spring 7, both ends of the spring 7 are respectively connected to the movable lock seat 6 and the locking hinge seat 5, and the telescopic direction of the spring 7 conforms to the direction in which the lock pin 8 is inserted into the lock groove 4a.

[0053] Among them, the locking hinge seat 5 has an inner groove for accommodating the rotation of the cylinder bracket 4 inside. The movable lock seat 6 is arranged outside the locking hinge seat 5. The locking hinge seat 5 is provided with a guiding hole 5a extending in an arc shape, and the center of the guiding hole 5a coincides with the rotation central axis of the movable lock seat 6. The lock pin 8 movably passes through the guiding hole 5a and moves along the length direction of the guiding hole 5a.

[0054] When the electric bed needs to be used, install the bed legs 10, turn the cylinder bracket 4 downward, the lock pin 8 first abuts against the end of the cylinder bracket 4. When the lock groove 4a of the cylinder bracket 4 is facing the lock pin 8, driven by the elastic force of the spring 7, the movable lock seat 6 rotates towards the cylinder bracket 4, driving the lock pin 8 to insert into the lock groove 4a, thereby completing the position locking of the cylinder bracket 4. During this process, the movement direction of the lock pin 8 is guided by the guiding hole 5a, so that the lock pin 8 can accurately insert into the lock groove 4a.

[0055] After the position of the cylinder bracket 4 is locked, the electric cylinder 3 and the movable plate can bear the load during use.

[0056] When entering the packaging state, directly rotate the movable lock seat 6 so that the lock pin 8 disengages from the lock groove 4a, and rotate the cylinder bracket 4 in the reverse direction to fold it. At the same time, drive the electric cylinder 3 to extend, so that the telescopic rod of the electric cylinder 3 is partially inserted into the receiving groove 4b of the cylinder bracket 4. As Figure 7 shown, the lock pin 8 abuts against one side of the cylinder bracket 4 and is pressed by the cylinder bracket 4. At the same time, as Figure 2 shown, the electric cylinder 3 and the cylinder bracket 4 are parallel to each other, and are parallel or nearly parallel to the bed frame 2.

[0057] The above is the preferred embodiment of the present invention. Those of ordinary skill in the art can also make various transformations or improvements on this basis. Without departing from the general concept of the present invention, these transformations or improvements should fall within the scope of protection required by the present invention.
