DETAILED DESCRIPTION

[0035] The present application is further described in detail below in conjunction with the accompanying drawings.

[0036] The present application discloses an electric bed leg structure, such as Figure 1 As shown, the bed frame 1 includes a thigh board 2 hinged on the bed frame 1, and a calf board 3 hinged on the thigh board 2. The bed frame 1 is horizontally arranged, and a horizontally arranged hip board is fixed to the upper end of the bed frame 1. One end of the thigh board 2 is hinged to the hip board, and the other end of the thigh board 2 is hinged to the calf board 3. Both the thigh board 2 and the calf board 3 can be rotated to a horizontal state and abut against the bed frame 1. The bed frame 1 is provided with a driving member for pushing the thigh board 2 to rotate upward. The driving member is connected to the position of the thigh board 2 near the calf board 3, so that when the thigh board 2 is pushed to move upward, the end of the calf board 3 near the thigh board 2 can also move upward accordingly.

[0037] like Figure 2 As shown, an activity space for the calf board 3 to rotate is provided between the thigh board 2 and the calf board 3, and four groups of connecting components 4 are provided between the thigh board 2 and the calf board 3 to connect the two. The connecting components 4 are arranged along the connection between the thigh board 2 and the calf board 3. The connecting components 4 include a first connecting member 41 installed under the thigh board 2 and a second connecting member 42 installed under the calf board 3. The first connecting member 41 and the second connecting member 42 are hinged, and the hinge point of the first connecting member 41 and the second connecting member 42 is located in the activity space, so that when it is necessary to add new accessories or perform maintenance, the calf board 3 can be directly turned upward, so that maintenance is more convenient.

[0038] like Figure 3As shown, the bed frame 1 is also provided with two groups of adjustment components 5 for adjusting the position of the calf board 3, and the adjustment components 5 are respectively located on both sides of the bed frame 1 and connected to the outermost connection component 4. The adjustment component 5 includes a first adjustment rod 51 hinged on the second connection member 42 and a second adjustment rod 52 hinged on the first adjustment rod 51, one end of the first adjustment rod 51 is connected to the first connection member 41, and the other end of the first adjustment rod 51 is connected to the second adjustment rod 52. The rotation axis of the first adjustment rod 51 and the second connection member 42 is located below the calf board 3, and the rotation axis of the second adjustment rod 52 and the first adjustment rod 51 is arranged below the first adjustment rod 51 which is arranged horizontally, and when the calf board 3 and the thigh board 2 are both in a horizontal state, the first adjustment rod 51 is arranged horizontally, and the end of the second adjustment rod 52 away from the first adjustment rod 51 is tilted downward. Therefore, when the thigh board 2 rotates upward, the first adjustment rod 51 and the second adjustment rod 52 can drive the calf board 3 to move, and the position and rotation trajectory of the calf board 3 can be restricted when moving.

[0039] Since the calf board 3 can be directly flipped upward, the calf board 3 will also be directly flipped upward when the electric bed is in use, thus affecting the use. Therefore, support feet 11 are provided on both sides of the bed frame 1, and the lower end surface of the support foot 11 is flush with the lower end surface of the bed frame 1, and the upper end surface of the support foot 11 is lower than the second adjustment rod 52 which is horizontally arranged, so that the support foot 11 is used to hinder the downward rotation of the second adjustment rod 52, so that when the thigh board 2 and the calf board 3 are in a horizontal state, the second adjustment rod 52 cannot be rotated downward, so that the calf board 3 cannot be flipped upward.

[0040] Since the end of the second adjustment rod 52 away from the first adjustment rod 51 is tilted downward, in order to keep the height of the rotation axis of the second adjustment rod 52 unchanged without extending the second adjustment rod 52, the second adjustment rod 52 includes a horizontal portion 521 and a bending portion 522 integrally formed with the horizontal portion 521, and the end of the horizontal portion 521 away from the bending portion 522 is connected to the first adjustment rod 51, and when the calf board 3 is in a horizontal state, the horizontal portion 521 remains horizontal. The end of the bending portion 522 away from the horizontal portion 521 is rotatably connected to the bed frame 1, and the end of the bending portion 522 away from the horizontal portion 521 is tilted downward, so that the position of the rotation axis of the bending portion 522 will not change without lengthening the entire length of the second adjustment rod 52.

[0041] The second adjustment rod 52 is located on the side of the first adjustment rod 51 close to the bed frame 1. The second adjustment rod 52 is arranged in a sheet shape, and the horizontal portion 521 is arranged close to the first adjustment rod 51. The end of the bent portion 522 away from the horizontal portion 521 is bent toward the bed frame 1, and the end close to the bed frame 1 is parallel to the vertical surface of the bed frame 1. Therefore, the rotation position of the second adjustment rod 52 is close to the bed frame 1 and the first adjustment rod 51, respectively, so that the rotation axis through which the second adjustment rod 52 is arranged is not easily deformed when the second adjustment rod 52 rotates.

[0042] In order to enhance the strength of the second adjustment rod 52, the overall width of the second adjustment rod 52 is increased and is greater than the width of the first adjustment rod 51. When the first adjustment rod 51 is in a horizontal state, the upper end of the horizontal portion 521 is higher than the first adjustment rod 51, and the lower end of the horizontal portion 521 is lower than the first adjustment rod 51. The strength of the second adjustment rod 52 is enhanced by increasing the width, so that the second adjustment rod 52 is not easily deformed.

[0043] Since the second adjusting rod 52 is higher than the first adjusting rod 51 and the area of ​​the second adjusting rod 52 facing the calf plate 3 is smaller, when the calf plate 3 is under pressure, it will directly abut against the second adjusting rod 52, resulting in an indentation on the calf plate 3, which affects the strength. Therefore, an abutting block 53 is provided on the first adjusting rod 51, and a mounting hole 511 is provided at the upper end of the first adjusting rod 51, and a mounting rod 531 is coaxially fixed to the lower end of the abutting block 53, and the mounting rod 531 is inserted into the mounting hole 511, and the lower end of the abutting block 53 abuts against the first adjusting rod 51, and the upper end of the abutting block 53 is higher than the upper end surface of the horizontal portion 521 and can abut against the lower side of the horizontally arranged calf plate 3, thereby supporting the calf plate 3.

[0044] The implementation principle of this embodiment is: when the electric bed needs to be repaired, the driving component is controlled to push the thigh board 2 and the calf board 3 to rotate upward, and then the calf board 3 is flipped upward so that the electric bed can be repaired or accessories can be added.

[0045] The embodiments of this specific implementation method are all preferred embodiments of the present application, and are not intended to limit the protection scope of the present application. Therefore, all equivalent changes made based on the structure, shape, and principle of the present application should be included in the protection scope of the present application.
