[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] like Figures 1 to 3 As shown:

[0031] Example 1: This utility model provides a leg support mechanism, including a leg support component 1. The leg support component 1 includes a mounting bracket 11. A set of leg support brackets 12 are slidably embedded on the mounting bracket 11. A driving component 13 is also fixedly installed on the mounting bracket 11. The driving component 13 is driven by an external power source.

[0032] The drive component 13 drives the leg support frame component 12 to move up and down;

[0033] As can be seen from the above, during operation, the drive component 13 fixed on the mounting bracket 11 operates under the drive of an external power source, driving a set of leg support brackets 12 that are slidably embedded on the mounting bracket 11 to move up and down, and can then stop at a specified height according to user needs, providing stable support for the legs, or move back and forth repeatedly to achieve the effect of leg activity.

[0034] Specifically, the mounting bracket 11 includes a mounting bracket body 111, on which a guide rod 112 is fixedly mounted, and a spring 113 is sleeved on the outer side of the guide rod 112.

[0035] The leg support frame 12 includes a push plate support frame 121, a guide plate 122 is provided at the lower end of the push plate support frame 121, and an inclined surface 124 is fixedly connected to the outer side of the push plate support frame 121.

[0036] The driving component 13 drives the push plate support frame 121 to move up and down, the guide plate 122 is limited and slidably embedded in the guide rod 112, and the spring 113 drives the guide plate 122 to move down along the guide rod 112.

[0037] Specifically, the driving component 13 is a cylinder, which can push the leg support frame 12 to move up and down.

[0038] Specifically, the driving component 13 includes a connecting plate 131, a set of trapezoidal push blocks 132 are fixedly installed on one side of the connecting plate 131, and an electric push rod 133 is fixedly installed on the other side of the connecting plate 131.

[0039] The bottom of the push plate support frame 121 is also provided with an inclined surface 124;

[0040] The end of the electric push rod 133 away from the connecting plate 131 is fixedly installed on the mounting frame body 111. The electric push rod 133 moves laterally to abut against the inclined surface 124 and drives the push plate support frame 121 to move upward.

[0041] Specifically, a set of guide rods 114 are also fixedly installed on the mounting frame body 111;

[0042] As can be seen from the above, when working, the control of the electric push rod 133 causes the connecting plate 131 to drive the trapezoidal push block 132 to move. The movement of the trapezoidal push block 132 will abut against the inclined surface 124, thereby causing the push plate support frame 121 to drive the guide plate 122 to move upward along the guide rod 112, thus facilitating use.

[0043] When the push plate support frame 121 drives the guide plate 122 to move upward along the guide rod 112, the spring 113 will be compressed. When the push plate support frame 121 disengages from the inclined plane 124, the spring 113 will reset and drive the guide plate 122 to move downward with the push plate support frame 121.

[0044] Example 2: An electric bed, including the leg support mechanism as described above, and also including bed frame assembly 2;

[0045] The bed assembly 2 includes a bed 21, which has an extension hole 22, an installation groove 23 on its lower side, and a bottom baffle 24 fixedly installed at the bottom of the bed 21 by bolts.

[0046] The leg support component 1 is fitted into the mounting groove 23 and is limited by the bottom baffle 24. The drive component 13 drives the leg support frame 12 to extend upward through the extension hole 22 and then extend to the bed surface.

[0047] As can be seen from the above, during installation, the leg support component 1 is inserted into the mounting groove 23 of the bed frame component 2 and is limited by the bottom baffle 24.

[0048] When in use, when the drive unit 13 is activated, the drive unit 13 drives the leg support frame 12 to move upward. The leg support frame 12 extends upward through the extension hole 22 on the bed frame 21 and extends to the bed surface, thereby realizing the height adjustment of the leg support area on the bed surface to meet the different leg support needs of users.
