In order to enable you to have a better understanding of the present invention, the preferred embodiments are described in detail below with accompanying drawings:

Please refer to FIG. 1 to FIG. 7 , the present invention provides an electric bed frame 10 including a base frame 20 and an adjustment frame assembly 30, wherein:

The base frame 20 (see FIGS. 1 to 7 ) is a rectangular frame, but the invention is not limited thereto. The above description is about an embodiment of the base frame 20 , but the embodiment is not limited to the above disclosed embodiment.

The adjustment frame assembly 30 (see FIGS. 1 to 7 ) is adjustably arranged on the top side of the base frame 20 . The adjustment frame assembly 30 includes a supporting frame 31 , a first adjustment frame 32 , a second adjustment frame 33 , a third adjustment frame 34 , a first driver 35 and a second driver 36 , wherein:

The supporting frame 31 (see FIGS. 1 to 7 ) is a rectangular frame, but is not limited thereto. The supporting frame 31 (see FIGS. 6 and 7 ) has a bearing thickness D between the top and bottom. The bottom side of the supporting frame 31 (see FIG. 2 ) is assembled (the assembly method can be implemented by screws) on the top side of the base frame 20 . The supporting frame 31 has a bearing thickness D, which facilitates the rapid assembly or disassembly of the adjustment frame set 30 and the base frame 20 . In other words, the adjustment frame set 30 can be rapidly assembled on the base frame 20 or rapidly disassembled from the base frame 20 . The supporting frame 31 has a bearing thickness D to support the first driver 35 and the second driver 36 to drive the first adjustment frame 32 , the second adjustment frame 33 and the third adjustment frame 34 to rise and fall.

The first adjustment frame 32 (see FIGS. 1 to 7 ) is a rectangular frame, but not limited thereto. The thickness of the first adjustment frame 32 in side view is less than the bearing thickness D of the bearing frame 31 in side view, so that the first adjustment frame 32 and the corresponding base frame 20 are spaced apart from each other and have a first spacing S1 (see FIG. 6 ) to maintain the first adjustment frame 32 in the state of providing the user with a flat lie as shown in FIG. 1 .

One side of the first adjustment frame 32 (see FIG. 4 ) is pivoted with one end of the first actuator 35 (the pivoting method can be implemented by a latch and a hinge as an example) on one side of the support frame 31 and close to the top and bottom of the support frame 31, respectively. The other end of the first actuator 35 is pivoted telescopically at or near the middle of the bottom of the first adjustment frame 32, so that the first adjustment frame 32 is located above the first actuator 35. Referring to FIG. 7 , the first actuator 35 is telescopically extended toward one end of the base frame 20 to lift the first adjustment frame 32 and mutually clamp the base frame 20 at a first tilt angle a1.

The first actuator 35 (see FIG. 4 ) has a first movable end 351 that is extended and retracted to lift the first adjustment frame 32 . The first actuator 35 is electrically driven to extend and retract the first movable end 351 . The first actuator 35 may be a linear actuator.

A plurality of reinforcing rods are disposed at the bottom of the first adjustment frame 32 to resist the thrust or pull generated by the extension and contraction of the first driver 35 on the first adjustment frame 32. Any two reinforcing rods are symmetrically disposed, any one reinforcing rod is disposed between any two reinforcing rods and arranged radially, and one end of any two reinforcing rods is assembled at the retractable pivot of the first driver 35, and the retractable pivot of the first driver 35 is disposed on any one reinforcing rod between any two reinforcing rods.

The second adjustment frame 33 (see FIGS. 1 to 7 ) is a rectangular frame, but is not limited thereto. The thickness of the second adjustment frame 33 in side view is less than the bearing thickness D of the bearing frame 31 in side view, so that the second adjustment frame 33 and the corresponding base frame 20 are spaced apart from each other and have a second spacing S2 (see FIG. 6 ) to maintain the second adjustment frame 33 in the state of providing the user with a flat lie as shown in FIG. 1 .

One side of the second adjustment frame 33 (please refer to FIG. 5 ) and one end of the second driver 36 are pivotally arranged on the other side of the supporting frame 31 and are respectively close to the top and bottom sides of the supporting frame 31 . The other end of the second driver 36 is telescopically pivotally arranged at the bottom edge of the second adjustment frame 33 , so that the second adjustment frame 33 is located above the second driver 36 .

The second adjustment frame 33 (see FIGS. 1 to 7 ) has two second auxiliary rods 331 , one end of which is pivoted on the other side of the supporting frame 31 and close to the bottom of the supporting frame 31 , and is located on both sides of the second driver 36 and below the second adjustment frame 33 .

The number of the second auxiliary rod 331 can also be one, the difference is that the second auxiliary rod 331 is located at one side of the second driver 36 .

The third adjustment frame 34 (see FIGS. 1-3 and 5-7 ) is a rectangular frame, but is not limited thereto. The thickness of the third adjustment frame 34 in side view is less than the bearing thickness D of the bearing frame 31 in side view, so that the third adjustment frame 34 and the corresponding base frame 20 are spaced from each other to have a third distance S3 (see FIG. 6 ) to maintain the third adjustment frame 34 in the state of providing the user with a flat lie as shown in FIG. 1 .

The other side of the second adjustment frame 33 (please refer to FIG. 5 ) and the other ends of the two second auxiliary rods 331 are spaced and pivotally arranged on one side of the third adjustment frame 34 .

The supporting frame 31, the second adjustment frame 33, the third adjustment frame 34 and the two second auxiliary rods 331 form a four-link structure, and can further form a parallel four-link structure. The second actuator 36 extends toward the other end of the base frame 20 to raise and lower the second adjustment frame 33 and link the third adjustment frame 34 to raise and lower. Please refer to FIG. 7. The second adjustment frame 33 and the base frame 20 are mutually clamped at a second tilt angle a2, and the second adjustment frame 33 and the third adjustment frame 34 are mutually clamped at a third tilt angle a3.

The linkage process of the second adjustment frame 33 and the third adjustment frame 34 produces two changes: first, when the third adjustment frame 34 and the base frame 20 are parallel to each other, the second tilt angle a2 is equal to the third tilt angle a3 (equal means that the acceptable error range is equal). Second, when the third adjustment frame 34 and the base frame 20 are not parallel to each other, the second tilt angle a2 is smaller than the third tilt angle a3, and at this time, the third adjustment frame 34 moves away from the side of the second adjustment frame 33 and approaches the base frame 20.

The first tilt angle a1, the second tilt angle a2 and the third tilt angle a3 mentioned above are respectively generated when the first adjustment frame 32, the second adjustment frame 33 and the third adjustment frame 34 are lifted. The first spacing S1 (please refer to FIG. 6), the second spacing S2 and the third spacing S3 mentioned above are respectively generated when the first adjustment frame 32, the second adjustment frame 33 and the third adjustment frame 34 are not lifted, and the first spacing S1 (please refer to FIG. 6), the second spacing S2 and the third spacing S3 correspond to the bearing thickness D.

The direction in which the second driver 36 extends toward one end of the base frame 20 (please refer to FIG. 7) is different from the direction in which the first driver 35 extends toward the other end of the base frame 20 (please refer to FIG. 7). In this way, the first driver 35 and the first adjustment frame 32 are brought into close contact with each other, and the first driver 35 extends toward the first adjustment frame 32 to lift the first adjustment frame 32 to generate a first tilt angle a1. Similarly, the second driver 36 and the second adjustment frame 33 are brought into close contact with each other, and the second driver 36 extends toward the second adjustment frame 33 to lift the second adjustment frame 33 to generate a second tilt angle a2, and links the third adjustment frame 34 to generate a third tilt angle a3. In this way, the components are brought close to each other during the lifting process to reduce exposure and eliminate the need for an outer cover to shield them, thereby reducing the use of outer cover materials and the number of steps for assembling the outer cover.

The second actuator 36 (see FIG. 5 ) has a second movable end 361 that is extended and retracted to lift the second adjustment frame 33 . The second actuator 36 is electrically driven to extend and retract the second movable end 361 . The second actuator 36 may be a linear actuator.

A plurality of reinforcing rods are disposed at the bottom of the second adjustment frame 33 to resist the thrust or pull generated by the extension and contraction of the second driver 36 on the second adjustment frame 33. Any two reinforcing rods are symmetrically disposed, any one reinforcing rod is disposed between any two reinforcing rods and arranged radially, and one end of any three reinforcing rods is assembled at the retractable pivot of the second driver 36.

The other ends of the two second auxiliary rods 331 are pivoted on two third supporting rods 341 further provided on one side of the third adjustment frame 34 , so that the pivoting position of the other side of the second adjustment frame 33 is located above the pivoting position of the other ends of the two second auxiliary rods 331 .

One end of the two third supporting rods 341 is connected to the bottom edge of the third adjustment frame 34, and the other end of the two third supporting rods 341 is against the top of the base frame 20 to maintain the third spacing S3. The number of third supporting rods 341 can be increased at the bottom edge of the third adjustment frame 34 as needed.

A plurality of first supporting rods 321 may also be disposed at the bottom edge of the first adjustment frame 32. The first supporting rods 321 abut against the top side of the base frame 20 to maintain the first spacing S1.

The above is an explanation of an embodiment of adjusting the frame set 30, but is not limited to the above disclosed embodiment.

The descriptions such as “first”, “second” and “third” mentioned in the present invention are used for distinction and do not represent the order of precedence.

In summary, the present invention provides an electric bed frame. The electric bed frame 10 facilitates the quick assembly or disassembly of the adjustment frame assembly 30 and the base frame 20 through the bearing thickness D of the bearing frame 31, so as to carry the first driver 35 and the second driver 36 to drive the first adjustment frame 32, the second adjustment frame 33 and the third adjustment frame 34 to rise and fall. The electric bed frame 10 extends and contracts in a direction different from that of the first driver 35 through the second driver 36, thereby reducing exposure to the outside during the lifting process without the need for an outer cover to shield, thereby reducing the use of outer cover materials and reducing the outer cover assembly process.
