The invention belongs to the technical field of elevator accessory products, and particularly discloses a toe guard device for a lift car of an elevator. The toe guard device comprises a fixed toe guard installed at the bottom of the lift car and a movable toe guard installed at the bottom of the fixed toe guard, the top of the movable toe guard is movably connected with the fixed toe guard through an elastic connecting piece in the vertical direction, and the lateral side of the movable toe guard and the lateral side of the fixed toe guard are each provided with an automatic locking structure, wherein the movable toe guard and the fixed toe guard relatively move in the vertical direction when the lift car of the elevator enters a pit, and the movable toe guard and the fixed toe guard are relatively fixed in the vertical direction when the lift car of the elevator leaves the pit. By means of the toe guard device, it can be guaranteed that the toe guards cannot be manually contracted when the lift car is not located at the pit, and can be passively contracted only after the lift car enters the pit, the length and the rigidity which are the same as those of an existing toe guard for the lift car when the lift car is not located at the pit are guaranteed, and the safety of a trapped person during rescuing when the lift car is not located at the pit can be sufficiently guaranteed. At the pit, as the toe guards for the lift car are automatically contracted, the pit depth can be reduced while the safety performance is guaranteed, and therefore the pit excavation cost is reduced.
