[0045] DETAILED DESCRIPTION

[0046] The present invention is described in detail below in conjunction with specific embodiments. The following embodiments will help those skilled in the art to further understand the present invention, but are not intended to limit the present invention in any form. It should be noted that, for those of ordinary skill in the art, several changes and improvements can also be made without departing from the concept of the present invention. These all belong to the protection scope of the present invention.

[0047] Basic Example C

[0048] like Figure 1 As shown, a deformable clamping linear motor provided according to the present invention includes: a first clamping body 501, a telescopic body 502, a second clamping body 503, and a moving part 1;

[0049] The first clamping body 501, the telescopic body 502, and the second clamping body 503 are connected in sequence;

[0050] The first clamping body 501 and the second clamping body 503 both include opening pieces;

[0051] The opening member includes an opening body 5041 and a deformation body 5042; wherein the deformation body 5042 is arranged between two opening walls of the opening body 5041; the moving member 1 passes through the through hole of the opening wall; the deformation body 5042 is preferably an energy-induced deformable material body or an energy-induced deformable structure, so that the present invention can be a cable motor or a cable-free motor.

[0052] The deformation body 5042 can change between a first shape and a second shape:

[0053] When the deformable body 5042 is in the first shape, the relative posture between the through holes of the two opening walls allows the moving part 1 to move freely;

[0054] When the deformation body 5042 is in the second shape, the relative position between the through holes of the two opening walls causes the moving part 1 to be locked.

[0055] The telescopic body 502 is located beside the moving part 1 , or the through hole of the telescopic body 502 through which the moving part 1 passes does not contact the moving part 1 .

[0056] Working principle:

[0057] Step A: the deformable body 5042 of the first clamping body 501 is extended, so that the first clamping body 501 locks the moving part 1; the second clamping body 503 keeps the moving part 1 in a released state;

[0058] Step B: the deformation body 5042 of the telescopic body 502 is extended, so that the second clamping body 503 moves rightward relative to the moving part 1;

[0059] Step C: the deformation body 5042 of the second clamping body 503 is extended so that the second clamping body 503 locks the moving part 1;

[0060] Step D: the deformation body 5042 of the first clamping body 501 is shortened, so that the first clamping body 501 releases the moving part 1;

[0061] Step E: The deformation body 5042 of the telescopic body 502 is shortened, so that the first clamping body 501 moves rightward relative to the moving part 1.

[0062] Execute steps A to E in sequence to achieve single-step movement. Repeat multiple times to achieve long-stroke movement.

[0063] Example C1

[0064] The telescopic body 502 includes one or more opening members connected in series.

[0065] Example C2

[0066] like Figure 2 As shown, the opening of the first clamping body 501, the opening of the telescopic body 502, and the opening of the second clamping body 503 are connected in sequence.

[0067] When the deformable body 5042 is in the first shape, the outer through hole walls of the opening bodies of the first clamping body 501 and the second clamping body 503 are inclined relative to the moving part 1, that is, an angle is formed between the axial direction of the outer through hole of the opening body and the axial direction of the moving part 1, and the inner through hole walls of the opening bodies of the first clamping body 501 and the second clamping body 503 are parallel to the moving part 1.

[0068] When the deformable body 5042 is in the second shape, the outer through hole walls of the opening bodies of the first clamping body 501 and the second clamping body 503 are inclined relative to the moving part 1, that is, an angle is formed between the axial direction of the outer through hole of the opening body and the axial direction of the moving part 1, and the inner through hole walls of the opening bodies of the first clamping body 501 and the second clamping body 503 are also inclined relative to the moving part 1 and the inclination is less than the inclination of the outer through hole wall, that is, the inclination of the inner through hole wall of the opening body allows the moving part 1 to move freely. The deformation amount of the two opening walls of the opening part is asymmetric. The asymmetry of the shape increases the movement effect and increases the friction force.

[0069] Example C3

[0070] like Figure 3 As shown, a mass block is fastened to any one of the opening of the first clamping body 501 , the opening of the telescopic body 502 , and the opening of the second clamping body 503 .

[0071] Alternatively, the mass distribution of the opening of the first clamping body 501, the opening of the telescopic body 502, and the opening of the second clamping body 503 is uneven.

[0072] In a variation, the telescopic body 502 and the second clamping body 503 may be omitted.

[0073] Working principle:

[0074] The mass block M is first moved toward the first direction at a relatively slow speed, and then the first clamping body 501 and / or the second clamping body 503 release the moving part 1 at a relatively fast speed, so that under the inertial force, the first clamping body 501 and / or the second clamping body 503 can undergo a relatively large displacement toward the first direction, and at the same time, the mass block M undergoes a relatively small displacement away from the first direction.

[0075] Example C4

[0076] like Figure 4 , Figure 5 As shown, the opening body has an elastic connecting body 508, wherein the elastic connecting body 508 includes an elastic hinge structure or a spring.

[0077] The deformation body 5042 and the elastic hinge are both located at the opening side of the opening body, both located at the non-opening side of the opening body, or respectively located at the opening side and the non-opening side.

[0078] Example C5

[0079] A deformable clamping linear motor comprises: a first clamping body 501 and a moving part 1; the first clamping body 501 comprises an opening part; the opening part comprises an opening body 5041 and a deformable body 5042; wherein the deformable body 5042 is arranged between two opening walls of the opening body 5041; the moving part 1 passes through a through hole of the opening wall; the deformable body 5042 can change between a first shape and a second shape: when the deformable body 5042 is in the first shape, the relative position between the through holes of the two opening walls allows the moving part 1 to move freely; when the deformable body 5042 is in the second shape, the relative position between the through holes of the two opening walls locks the moving part 1; the mass distribution of the first clamping body 501 is uneven or a mass block M is arranged. The deformable body 5042 drives the opening body 5041 to move when it is alternately charged quickly and discharged slowly, or when it is alternately charged slowly and discharged quickly.

[0080] Take the deformable body 5042 as an electrodeformable material as an example:

[0081] like Figure 6 As shown, when the deformable body 5042 is alternately charged quickly and released slowly, that is, input Figure 6 In the signal Sign in the upper left middle portion, S represents the amplitude. Due to the inertia of the mass block M, the left side wall of the opening body 5041 moves greatly to the left during rapid energy charging, and moves slightly to the right during slow energy release, thereby completing one step to the left overall.

[0082] like Figure 6 As shown, when the deformable body 5042 is alternately rapidly discharged and slowly charged, that is, input Figure 6 In the signal Sign in the upper right middle portion, S represents the amplitude. Due to the inertia of the mass block M, the right side wall moves greatly to the right during slow charging, and the right side wall of the opening 5041 moves slightly to the left during fast energy release, thereby completing one step to the right overall.

[0083] like Figure 7 As shown, the opening body 5041 is fixed, and when the deformable body 5042 is alternately charged quickly and released slowly, the moving part 1 moves to the left; when the deformable body 5042 is alternately charged slowly and released quickly, the moving part 1 moves to the right.

[0084] In the description of the present application, it should be understood that the terms "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the referred device or element must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present application.

[0085] The above describes the specific embodiments of the present invention. It should be understood that the present invention is not limited to the above specific embodiments, and those skilled in the art can make various changes or modifications within the scope of the claims, which does not affect the essence of the present invention. In the absence of conflict, the embodiments of the present application and the features in the embodiments can be combined with each other arbitrarily.
