Preferably, only the rear segment body 2 is connected with a driving device for driving the unfolding and folding.
The specific working process and principle of the folding and unfolding motion assembly of the embodiment are as follows:
when the front section body 1 and the rear section body 2 of the folding and unfolding moving assembly are in a folded state, the blocking piece 5 of the linkage mechanism is kept at the third position under the action of the elastic piece 6, the blocking piece 5 is matched with the blocking matching part 41 to prevent the locking component 4 from moving from the first position to the second position, the locking component 4 is positioned at the first position, and the locking seat 7 is clamped between the first matching part 81 and the second matching part 82 to lock and fix the rear section body 2 and the basic section body 3; the locking member 4 is withdrawn from the locating hole 11 and the front body 1 is movable relative to the rear body 2, see figure 1.
When the folding and unfolding motion assembly is unfolded, the locking part 4 locks and fixes the rear section body 2 and the basic section body 3, and only the front section body 1 can be unfolded firstly when unfolded, and the front section body 1 is firstly contacted with the push matching part 51 of the blocking piece 5 when moving from a folding state to an unfolding state, which is shown in fig. 2; then, the push fit part 51 is pushed to enable the blocking piece 5 to overcome the action of the elastic piece 6 and move to the fourth position until the front section body 1 moves to the unfolding state, the blocking piece 5 moves to the fourth position, and at the moment, the blocking piece 5 is separated from the blocking fit part 41, so that the blocking effect on the locking component 4 is relieved, and the reference of fig. 3 is made; then the front section body 1 drives the rear section body 2 to move from a folded state to an unfolded state, in the process that the rear section body 2 moves from the folded state to the unfolded state, the locking seat 7 pushes the first matching part 81 to force the clamping hook 8 to swing so as to drive the locking component 4 to move from the first position to the second position, the locking component 4 is inserted into the positioning hole 11 to prevent the front section body 1 and the rear section body 2 from moving relatively, and the rear section body 2 and the front section body 1 are locked and fixed, as shown in fig. 4; until the rear segment 2 moves to the deployed state, see fig. 5.
The action sequence of the folding and unfolding motion assembly is opposite to that of the folding and unfolding motion assembly, because when the front section body 1 and the rear section body 2 are in the unfolding state, the locking component 4 keeps the rear section body 2 and the front section body 1 locked and fixed, only the rear section body 2 can be folded firstly when folded, the clamping hook 8 is not contacted with the locking seat 7 when the rear section body 2 moves from the unfolding state to the folding state, the locking component 4 is kept at the second position, until the rear section body 2 moves to the folding state, the locking seat 7 pushes the second matching part 82 to force the clamping hook 8 to swing to drive the locking component 4 to move from the second position to the first position, at the moment, the locking seat 7 is clamped between the first matching part 81 and the second matching part 82 to lock and fix the rear section body 2 and the base section body 3, and simultaneously the locking component 4 exits from the positioning hole 11, so that the front section body 1 can move relative to the rear section body 2, and then the front section body 1 moves from the unfolding state to the folding state, in the process that the front section body 1 moves from the unfolding state to the folding state, the front section body 1 is separated from the push matching part 51 of the blocking piece 5, the blocking piece 5 automatically moves to the third position under the action of the elastic piece 6, the locking part 4 is prevented from moving from the first position to the second position, and the rear section body 2 and the basic section body 3 are kept locked and fixed; and the whole folding and unfolding motion assembly is folded until the front section body 1 moves to a folding state.
A multi-stage linear motion platform includes the stowing and deploying motion assembly of this embodiment. In a specific application, the multistage linear motion platform can only comprise three sections, namely a front section 1, a rear section 2 and a base section 3. The multistage linear motion platform also can comprise more than four sections of joint bodies which are sequentially arranged, and any adjacent three sections of joint bodies form a folding and unfolding motion assembly.
