[0042] Unless otherwise defined, all terms (including technical and scientific terms) used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. It will be further understood that terms, such as those defined in commonly used dictionaries, should be interpreted as having a meaning that is consistent with their meaning in the context of the relevant art and the present disclosure and will not be interpreted in an overly literal sense.

[0043] The specific embodiments of the present application will be further described in the following with reference to the drawings.

[0044] As shown in Figures 1 to 3 The embodiment provides a sliding structure 100, which comprises a guide assembly 10, a first sliding piece 20, a second sliding piece 30, a roller assembly 40 and an elastic piece 50.

[0045] For the convenience of subsequent reading, the present application introduces the first direction Z, the second direction X and the third direction Y to describe the embodiments of the present application. The first direction Z, the second direction X and the third direction Y can be three mutually non-parallel straight line directions in space; further, the first direction Z, the second direction X and the third direction Y can be three mutually perpendicular directions in a three-dimensional coordinate system (three-dimensional Cartesian coordinate system). In the subsequent embodiments, the first direction Z is taken as the Z-axis direction of the coordinate axis of the three-dimensional coordinate system, the second direction X is taken as the X-axis direction of the coordinate axis of the three-dimensional coordinate system, and the third direction Y is taken as the Y-axis direction of the coordinate axis of the three-dimensional coordinate system.

[0046] The guide assembly 10 is arranged along the first direction Z, and the first sliding piece 20 is configured to be slidable along the first direction Z relative to the guide assembly 10 to guide the first sliding piece 20 to slide along the first direction Z through the guide assembly 10. The second sliding piece 30 is slidably connected to the first sliding piece 20 along the second direction X. The roller assembly 40 comprises a first roller 41 and a second roller 42, and the first roller 41 is arranged at a first side of the guide assembly 10 along the second direction X, and the second roller 42 is arranged at a second side of the guide assembly 10 away from the first roller 41. The first roller 41 is rotatably connected to the first sliding piece 20, and the second roller 42 is rotatably connected to the second sliding piece 30, and the first roller 41 and the second roller 42 are configured to roll on the guide assembly 10. One end of the elastic piece 50 is elastically connected to the second sliding piece 30, and the other end of the elastic piece 50 is elastically connected to the first sliding piece 20, and the elastic piece 50 is configured to provide an elastic force to the second sliding piece 30 to elastically abut the second roller 42 against the guide assembly 10.

[0047] Thus, in the sliding structure 100 of the present application, one end of the elastic member 50 is elastically connected to the second sliding member 30, and the other end of the elastic member 50 is elastically connected to the first sliding member 20. On one hand, the elastic member 50 provides the second sliding member 30 with an elastic force to move towards the side of the first roller 41, so as to elastically abut the second roller 42 connected to the second sliding member 30 against the guide assembly 10. On the other hand, the elastic member 50 can also exert a counterforce on the first sliding member 20, so as to make the first sliding member 20 have a tendency to move towards the side of the first roller 41, and thus make the first sliding member 20 drive the first roller 41 connected thereto to also abut against the guide assembly 10, so as to ensure that the roller assembly 40 and the guide assembly 10 maintain a relatively stable cooperation relationship and are not easy to be loosened, and make the sliding of the first sliding member 20 more stable and smooth.

[0048] Please combine Figures 1 to 3 In an embodiment, the guide assembly 10 comprises a first guide 11 and a second guide 12, which are arranged in parallel along the second direction X. The first guide 11 and the second guide 12 are structures such as optical axes, and the extension directions of the first guide 11 and the second guide 12 are parallel to the first direction Z.

[0049] In the second direction X, the first roller 41 can roll on the side of the first guide 11 away from the second guide 12, so that the first roller 41 can move relative to the first guide 11 along the extension direction of the first guide 11. In the second direction X, the second roller 42 can roll on the side of the second guide 12 away from the first guide 11, so that the second roller 42 can move relative to the second guide 12 along the extension direction of the second guide 12.

[0050] In particular, the outer circumferential surface of the first roller 41 is provided with an annular groove 410, which is arranged around the outer circumferential surface of the first roller 41. In the radial direction of the first roller 41, the annular groove 410 is recessed inward from the outer circumferential surface of the first roller 41. The annular groove 410 is used to accommodate the first guide 11, so that the first roller 41 will not deviate during the movement relative to the first guide 11.

[0051] Correspondingly, the outer circumferential surface of the second roller 42 is also provided with an annular groove 410, which has the same structure and principle as the annular groove 410 provided on the first roller 41, and will not be described again.

[0052] Please combine Figures 1 to 4 In an embodiment, the first sliding member 20 comprises a first zone 21 and a second zone 22.

[0053] The first zone 21 is arranged in parallel to the guide assembly 10 along the third direction Y, and in the second direction X, the two ends of the first zone 21 respectively exceed the first guide 11 and the second guide 12.

[0054] The number of the second sections 22 is two, and the two second sections 22 are respectively arranged at two opposite sides of the guide assembly 10 along the second direction X. The two second sections 22 are respectively integrally formed at two opposite ends of the first section 21 along the second direction X. The second section 22 protrudes towards the guide assembly 10 from the side of the first section 21 close to the guide assembly 10 along the third direction Y.

[0055] It can be understood that in other embodiments, the two second sections 22 can be detachably connected with the first section 21.

[0056] In the embodiment, the first roller 41 is rotatably connected with the first section 21. The first roller 41 is located between the first guide 11 and one of the second sections 22 along the second direction X, and the second roller 42 is located between the second guide 12 and the other second section 22 along the second direction X, so as to ensure that the first roller 41 and the second roller 42 can clamp the guide assembly 10 from two sides of the guide assembly 10 along the second direction X, and ensure the stability of the first sliding member 20 during sliding.

[0057] When the first sliding member 20 slides relative to the guide assembly 10, the first roller 41 and the second roller 42 are driven by the first sliding member 20 to slide relative to the guide assembly 10, and the first roller 41 and the second roller 42 roll relative to the guide assembly 10 during sliding relative to the guide assembly 10, thereby reducing the friction between the first roller 41 and the second roller 42 and the guide assembly 10.

[0058] In the embodiment, the number of the first roller 41 and the second roller 42 is two. The two first rollers 41 are arranged at intervals along the first direction Z, and the two first rollers 41 are rotatably installed on the first section 21 through shaft members. The two second rollers 42 are arranged at intervals along the first direction Z, and the two second rollers 42 are rotatably installed on the second sliding member 30 through shaft members.

[0059] It can be understood that in other embodiments, the number of the first roller 41 and the second roller 42 can also be three or more.

[0060] Please refer to the combination of Figures 1 to 4In an embodiment, a sliding gap 212 is provided between the second sliding member 30 and the first sliding member 20 in the second direction X. The sliding gap 212 is configured to allow the second sliding member 30 to move towards the side close to the first roller 41 and the side away from the first roller 41 in the second direction X, so that the second sliding member 30 can be offset relative to the first sliding member 20 in the second direction X under the elastic force of the elastic member 50, to ensure that the second roller 42 can always be in abutting contact with the guide assembly 10 under the elastic force of the elastic member 50 when the first sliding member 20 is offset in the second direction X due to machining errors or assembly errors of the partial sections of the first guide member 11 or the second guide member 12, thereby improving the sliding accuracy of the first sliding member 20 and avoiding the offset of the first sliding member 20 during sliding.

[0061] In the embodiment, the first sliding member 20 is provided with a sliding groove 210. In the third direction Y, the sliding groove 210 extends from the side of the first section 21 close to the second guide member 12 to the side away from the second guide member 12, and the sliding groove 210 does not penetrate the first section 21 in the third direction Y.

[0062] The second sliding member 30 is located in the sliding groove 210, and in the second direction X, the groove width of the sliding groove 210 is greater than the width of the second sliding member 30, so that there is space for the second sliding member 30 to slide in the sliding groove 210.

[0063] In the second direction X, the groove wall of the side of the sliding groove 210 close to the first roller 41 is the first groove wall P1, the groove wall of the side of the sliding groove 210 away from the first roller 41 is the second groove wall P2, and the second sliding member 30 is located between the first groove wall P1 and the second groove wall P2.

[0064] When the second roller 42 abuts against the second guide member 12, the second sliding member 30 is spaced apart from the first groove wall P1 and the second groove wall P2 to form a sliding gap 212 therebetween, to ensure that the second roller 42 can move towards the side close to the second guide member 12 or the side away from the second guide member 12 in the sliding groove 210 in the second direction X, to ensure that the second roller 42 can always be in abutting contact with the second guide member 12 during the sliding of the first sliding member 20.

[0065] In the embodiment, the elastic member 50 is a compression spring, the elastic member 50 is in a compressed state, and the elastic member 50 is located between the second groove wall P2 and the second sliding member 30. One end of the elastic member 50 is elastically connected to the second sliding member 30, and the other end of the elastic member 50 is elastically connected to the second groove wall P2, to always provide the second sliding member 30 with an elastic force for moving towards the side of the first roller 41.

[0066] It is understood that in other embodiments, the elastic member 50 can also be a tension spring, the elastic member 50 is in a tension state, and the elastic member 50 is located between the first slot wall P1 and the second sliding member 30. One end of the elastic member 50 is elastically connected to the second sliding member 30, and the other end of the elastic member 50 is elastically connected to the first slot wall P1, so as to always provide the second sliding member 30 with an elastic force moving toward the side of the first roller 41 through the elastic member 50. The specific type and mounting position of the elastic member 50 can be selected according to actual design needs.

[0067] Please combine Figures 1 to 4 In an embodiment, the first sliding member 20 is provided with a through hole 211. Along the third direction Y, the through hole 211 extends from the surface of the side of the first section 21 away from the second guide 12 to the communication slot 210.

[0068] The sliding structure 100 further comprises a connecting member 80 penetrating the through hole 211. One end of the connecting member 80 is connected to the second sliding member 30, and the other end of the connecting member 80 penetrates out of the through hole 211.

[0069] The connecting member 80 is generally cylindrical in structure, and the shape of the through hole 211 is generally oval. Along the second direction X, the hole diameter of the through hole 211 is greater than the shaft diameter of the connecting member 80, so that a gap 213 is formed between the hole wall of the through hole 211 and the outer peripheral surface of the connecting member 80 in the second direction X, and the gap 213 allows the connecting member 80 to move in the second direction X within the through hole 211 relative to the first sliding member 20.

[0070] In particular, along the second direction X, the hole wall of the side of the through hole 211 close to the first roller 41 is used to abut against the connecting member 80, so as to limit the maximum stroke of the connecting member 80 moving in the second direction X toward the side of the first roller 41, thereby avoiding that the second roller 42 is too tightly abutted against the second guide 12, resulting in excessive friction between the second roller 42 and the second guide 12.

[0071] In the present embodiment, the end of the connecting member 80 away from the second sliding member 30 penetrates out of the through hole 211 and is exposed to the second sliding member 30, and the outer peripheral surface of the end of the connecting member 80 penetrating out of the through hole 211 is provided with a limiting portion 81, and the outer contour of the limiting portion 81 exceeds the hole wall of the through hole 211. Along the third direction Y, the limiting portion 81 and the first sliding member 20 abut against each other, so as to avoid that the connecting member 80 slides out of the through hole 211 along the third direction Y toward the side close to the second guide 12. In addition, along the third direction Y, the second sliding member 30 is abutted by the bottom wall of the slot 210, thereby avoiding that the connecting member 80 slides out of the through hole 211 along the third direction Y toward the side away from the second guide 12, and further achieving the limiting of the second sliding member 30 relative to the first sliding member 20 in the third direction Y.

[0072] Please combine Figures 2 to 4In an embodiment, the second slot wall P2 is provided with a first guide hole 221 extending along the second direction X and communicating with the sliding groove 210.

[0073] The sliding structure 100 further comprises a first guide slider 60 at least partially slidably arranged in the first guide hole 221 along the second direction X, and the elastic member 50 is elastically connected to the first guide slider 60 at an end away from the second sliding member 30, so as to guide the elastic member 50 to slide along the second direction X through the sliding of the first guide slider 60 in the first guide hole 221.

[0074] In the embodiment, the second slot wall P2 is further provided with a second guide hole 222 extending along the second direction X and communicating with the sliding groove 210.

[0075] The sliding structure 100 further comprises a second guide slider 70 at least partially slidably arranged in the second guide hole 222 along the second direction X, and the second guide slider 70 is connected to the second sliding member 30, so as to guide the second sliding member 30 to slide along the second direction X through the sliding of the second guide slider 70 in the second guide hole 222.

[0076] In particular, the number of the second guide holes 222 is two. Along the first direction Z, the two second guide holes 222 are arranged at intervals, and the first guide hole 221 is located between the two second guide holes 222. Correspondingly, the number of the second guide sliders 70 is also two, and the two second guide sliders 70 are respectively slidably connected to the two second guide holes 222, so as to improve the stability of the second sliding member 30 when sliding.

[0077] Please refer to Figure 5 , and refer to Figure 1 In an embodiment, the sliding structure 100 further comprises a driving assembly 90, which comprises a driving member 91 and a transmission mechanism 92. The driving member 91 is drivingly connected to the transmission mechanism 92 to provide a driving force to the transmission mechanism 92. The transmission mechanism 92 is drivingly connected to the first sliding member 20, and based on the above-mentioned driving force, the transmission mechanism 92 drives the first sliding member 20 to slide along the first direction Z.

[0078] The transmission mechanism 92 is a lead screw 921 transmission mechanism 92, and the transmission mechanism 92 comprises a lead screw 921 and a lead screw nut 922. The extension direction of the lead screw 921 is parallel to the first direction Z, and along the second direction X, the lead screw 921 is located between the first guide 11 and the second guide 12, and the lead screw 921 is arranged at intervals with the first guide 11 and the second guide 12.

[0079] The driving member 91 is an electric motor or a motor, etc. The driving member 91 is drivingly connected to the lead screw 921 to drive the lead screw 921 to rotate. The lead screw nut 922 is sleeved on the outer circumferential surface of the lead screw 921 and is threadedly engaged with the lead screw 921 to realize the movement of the lead screw nut 922 along the first direction Z through the rotation of the lead screw 921.

[0080] The first section 21 of the first sliding member 20 is detachably connected to the lead screw nut 922, and can be connected by a fastener such as a screw, etc. to drive the first sliding member 20 to slide along the first direction Z relative to the guide assembly 10 through the lead screw nut 922.

[0081] It can be understood that in other embodiments, the transmission mechanism 92 can also be a cylinder sliding table or other mechanism.

[0082] As shown in Figures 5 to 7 , and referring to Figure 1 , the embodiment of the present application also provides a stereoscopic printer frame 200, which comprises a frame body 1 and at least one sliding structure 100 described above, and the at least one sliding structure 100 is arranged on the frame body 1. The frame body 1 comprises side plates 101, a top plate 103 and a bottom plate 102, and the at least one sliding structure 100 is arranged on the side plates 101.

[0083] The side plates 101 are arranged along the first direction Z, and the number of the side plates 101 is two, and the two side plates 101 are arranged in a spaced manner along the third direction Y.
