Abstract

This invention relates to a mechanical adaptive bidirectional self-locking structure, comprising a guide rail, a drive mechanism slidably mounted on the guide rail, and a motion mechanism. The drive mechanism includes a first locking component and a triggering component. The first locking component locks the drive mechanism relative to the guide rail when the drive mechanism tends to move towards the motion mechanism, preventing the drive mechanism from moving along the guide rail towards the motion mechanism. The motion mechanism includes a second locking component, which is triggered by the triggering component during the drive mechanism's movement away from the motion mechanism, thereby locking the motion mechanism bidirectionally relative to the guide rail. This mechanical adaptive bidirectional self-locking structure can achieve bidirectional self-locking at any position of the motion mechanism. When the motion mechanism reaches the desired contact point, it is stopped by external contact triggering, and after the drive mechanism continues to move a certain distance, it automatically adapts and self-locks at the desired self-locking position. The control logic is simple, improving the stability and accuracy of this part of the system.

Description

Technical Field

[0001] This invention relates to the field of transmission, and more specifically, to a mechanical adaptive bidirectional self-locking structure. Background Technology

[0002] In the existing technology, the mechanical self-locking mechanism used in linear motion mechanisms is mainly unidirectional locking, while most bidirectional self-locking structures are fixed-point bidirectional self-locking based on specific positioning points, which cannot adapt to the working conditions at any position.

[0003] In existing mechanical self-locking mechanisms, structures capable of locking at any position are mostly used for unidirectional self-locking, or can only achieve fixed-point bidirectional self-locking by setting up special latching structures at certain specific positions. When encountering working conditions that require bidirectional locking of linear motion at any position, only some electrical auxiliary structures, such as motors, electromagnets, and suction cups, can be used.

[0004] Some mechanical bidirectional self-locking mechanisms cannot adapt to the required self-locking position through the movement of parts and external forces; they can only remain stationary in a position without active drive or require additional force sensors for detection. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to provide a mechanical adaptive bidirectional self-locking structure to address the above-mentioned deficiencies of the prior art.

[0006] The technical solution adopted by the present invention to solve its technical problem is: to construct a mechanical adaptive bidirectional self-locking structure, including a guide rail, a drive mechanism and a motion mechanism respectively slidably mounted on the guide rail;

[0007] The drive mechanism includes a first locking component and a triggering component. The first locking component is used to lock the drive mechanism relative to the guide rail when the drive mechanism has a tendency to move toward the motion mechanism, thereby preventing the drive mechanism from moving along the guide rail toward the motion mechanism.

[0008] The motion mechanism includes a second locking component, which is triggered by the triggering component during the movement of the drive mechanism away from the motion mechanism to bidirectionally lock the motion mechanism relative to the guide rail.

[0009] In some embodiments, the driving mechanism includes a driving slider and a driving component;

[0010] The drive slider slides with the guide rail, and the trigger component is connected to the drive slider;

[0011] The driving component is movably coupled with the driving slider so that it can move back and forth relative to the driving slider in the guiding direction of the guide rail, thereby driving the first locking component to lock and unlock the driving slider.

[0012] In some embodiments, the drive slider is provided with a first guide surface, and the first guide surface and the guide rail have an angle between them;

[0013] The first locking component includes a first elastic element and a first pin. The first elastic element is connected between the drive component and the first pin. The first pin is located within the angle formed by the first guide surface and the guide rail. The first elastic element provides an elastic force to the first pin to engage with the first guide surface, thereby achieving self-locking of the drive mechanism.

[0014] In some embodiments, the triggering component includes a connector and a trigger portion disposed on the connector. The connector is connected to the drive slider, and the trigger portion cooperates with a second locking component to drive the trigger portion to trigger the second locking component to achieve bidirectional self-locking.

[0015] In some embodiments, the connector is covered outside the guide rail, and the two opposite sides of the connector are respectively provided with a first guide groove arranged along the guide direction. The two ends of the first pin pass through the first guide grooves on both sides, and the two ends of the first pin are respectively connected to the first elastic element between the drive assembly.

[0016] In some embodiments, the connector is provided with a limiting port, and the driving component cooperates with the limiting port. The limiting port limits the range of the driving component's back-and-forth movement to achieve locking and unlocking of the first locking component.

[0017] In some embodiments, the second locking component includes a self-locking base and a drive element;

[0018] The self-locking base slides with the guide rail, and the driving member is rotatably mounted on the self-locking base between the self-locking position and the unlocking position. The triggering component abuts against the driving member and drives the driving member to rotate to the self-locking position, so that the second locking component locks the motion mechanism bidirectionally relative to the guide rail.

[0019] In some embodiments, the second locking component further includes a second pin, a third pin, a second elastic element, and a third elastic element. The self-locking base is provided with a second guide groove, a second guide surface, and a third guide surface. The second guide groove extends along the guiding direction of the guide rail. The second guide surface and the third guide surface are respectively angled with the guide rail, and the openings of the angles are opposite to or opposite to each other.

[0020] The second pin passes through the second guide groove and is located within the angle formed by the second guide surface and the guide rail. The third pin is located within the angle formed by the third guide surface and the guide rail. The third elastic element connects the second pin and the third pin.

[0021] When the driving member is in the self-locking position, the driving member is separated from the second pin, and the third elastic member provides elastic force to the second pin and the third pin respectively against the second guide surface and the third guide surface, thereby realizing bidirectional self-locking;

[0022] When the trigger component moves toward the motion mechanism, the drive component rotates to the unlock position following the movement of the trigger component under the drive of the second elastic element. The rotation of the drive component simultaneously causes the second pin to separate from the second guide surface, thereby driving the motion mechanism to move.

[0023] In some embodiments, after the drive member rotates following the movement of the trigger component, the drive mechanism abuts against the self-locking base.

[0024] In some embodiments, the triggering component is provided with a third guide groove, the third guide groove extends along the guiding direction of the guide rail, and the third pin is engaged in the third guide groove, allowing the third pin to move along the third guide groove.

[0025] In some embodiments, the drive member includes a laterally extending first drive portion and a second drive portion, the first drive portion being abutted against by the triggering component, the second drive portion being used to drive the second pin to separate from the second guide surface, and the second elastic member being connected to the second drive portion.

[0026] In some embodiments, the motion mechanism further includes a first slider and a second slider for mounting the self-locking base. The first slider and the second slider are spaced apart on the guide rail along the guide direction, and the self-locking base is connected between the first slider and the second slider.

[0027] In some embodiments, the second locking component includes two driving members, two second elastic members, and two third elastic members. The two driving members are rotatably disposed on two opposite sides of the self-locking base. The two second elastic members are located on both sides of the triggering component and are respectively connected to the driving members on both sides. The two third elastic members are respectively disposed on two opposite sides of the self-locking base and are connected to the ends of the second pin and the third pin on their respective sides.

[0028] In some embodiments, the motion mechanism is further provided with a stop portion for being blocked and stopped when reaching a set position, and a sensing device is provided between the drive mechanism and the motion mechanism for sensing that the drive mechanism is moving away from the motion mechanism after the motion mechanism is blocked and stopped, so as to stop the driving force applied to the drive mechanism.

[0029] The mechanical adaptive bidirectional self-locking structure of the present invention has the following advantages: the mechanical adaptive bidirectional self-locking structure can realize bidirectional self-locking at any position of the moving mechanism, and when the moving mechanism reaches the required contact point, it is stopped by external contact trigger, and after the driving mechanism continues to move a certain distance, it automatically adapts to self-locking at the required self-locking position. The control logic is simple, which improves the stability and accuracy of this part of the system. Attached Figure Description

[0036] To provide a clearer understanding of the technical features, objectives, and effects of the present invention, specific embodiments of the present invention will now be described in detail with reference to the accompanying drawings.

[0037] like Figure 1 As shown, a preferred embodiment of the mechanical adaptive bidirectional self-locking structure of the present invention includes a guide rail 1, a drive mechanism 2 and a motion mechanism 3 respectively slidably mounted on the guide rail 1.

[0038] The drive mechanism 2 includes a first locking component 21 and a triggering component 22. The first locking component 21 is used to lock the drive mechanism 2 relative to the guide rail 1 when the drive mechanism 2 has a tendency to move toward the motion mechanism 3, thereby preventing the drive mechanism 2 from moving along the guide rail 1 toward the motion mechanism 3.

[0039] The motion mechanism 3 includes a second locking component 31, which is triggered by the trigger component 22 during the movement of the drive mechanism 2 away from the motion mechanism 3, so as to lock the motion mechanism 3 bidirectionally relative to the guide rail 1.

[0040] This invention can achieve bidirectional self-locking at any position of the motion mechanism 3. When the motion mechanism 3 reaches the required contact point, it is stopped by external contact trigger. After the drive mechanism 2 continues to move a certain distance, it automatically adapts to self-locking at the required self-locking position C. The control logic is simple, which improves the stability and accuracy of this part of the system.

[0041] Combination Figures 1 to 3 As shown, the drive mechanism 2 includes a drive slider 23 and a drive component 24. The drive slider 23 slides with the guide rail 1, and the trigger component 22 is connected to the drive slider 23.

[0042] Furthermore, the drive assembly 24 is connected to an external power input mechanism, allowing external force to be applied to the drive assembly 24. The drive assembly 24 is movably engaged with the drive slider 23, enabling it to move back and forth relative to the drive slider 23 in the guiding direction of the guide rail 1, thereby driving the first locking assembly 21 to lock and unlock the drive slider 23.

[0043] In this embodiment, the drive component 24 can move within a limited range between the working position A and the locking position B. When the drive mechanism 2 drives the motion mechanism 3 to move, the drive component 24 is located at the working position A close to the motion mechanism 3. When the motion mechanism 3 is stopped by the resistance, the drive component 24 will continue to move to the locking position B in the direction away from the motion mechanism 3 under the continued action of the external force, thereby realizing the locking of the drive mechanism 2 and triggering the motion mechanism 3 to achieve bidirectional self-locking.

[0044] In some embodiments, the motion mechanism 3 is further provided with a stop part 32 for being stopped when it reaches a set position. When the motion mechanism 3 reaches the contact point, the stop part 32 stops moving after it comes into contact with the contact point. The drive mechanism 2, under the action of the external driving force, will make the drive component 24 continue to move away from the motion mechanism 3.

[0045] A sensing device 4 is provided between the drive mechanism 2 and the motion mechanism 3, which is used to sense that the drive mechanism 2 is away from the motion mechanism 3 after the motion mechanism 3 is blocked and stopped, so as to stop the driving force applied to the drive mechanism 2.

[0046] Preferably, in this embodiment, when the drive mechanism 2 moves away from the motion mechanism 3 to the locked position B, the sensing device 4 is triggered to shut off the driving force applied to the drive mechanism 2. During the movement of the drive mechanism 2 away from the motion mechanism 3, the trigger component 22 triggers the motion mechanism 3 to achieve self-locking, and the trigger component 22 and the drive slider 23 stop. At the same time, the drive component 24 continues to move to the locked position B under the action of the driving force. The drive component 24 drives the first locking component 21 to work, so that the first locking component 21 locks the drive slider 23, preventing the drive slider 23 and the trigger component 22 from getting close to the motion mechanism 3, and keeping the motion mechanism 3 self-locked.

[0047] Furthermore, when unlocking is required, force is applied to the drive component 24 toward the motion mechanism 3, causing the drive component 24 to move to the working position A. The first locking component 21 unlocks, and under the drive of the drive component 24, the drive mechanism 2 moves toward the motion mechanism 3, triggering component 22 to release the self-locking of the motion mechanism 3. The motion mechanism 3 is unlocked and can continue to move on the guide rail 1.

[0048] In some embodiments, the drive slider 23 is provided with a first guide surface 231, and the first guide surface 231 has an angle with the guide rail 1. Preferably, the angle between the first guide surface 231 and the guide rail 1 is open towards the motion mechanism 3.

[0049] The first locking component 21 includes a first elastic element 211 and a first pin 212. The first elastic element 211 is connected between the drive component 24 and the first pin 212. The first pin 212 is located within the angle formed by the first guide surface 231 and the guide rail 1. The first elastic element 211 provides an elastic force to the first pin 212 to engage with the first guide surface 231, so as to realize the self-locking of the drive mechanism 2.

[0050] When the drive assembly 24 moves to the locked position B, the first pin 212 is driven by the first elastic element 211 to engage within the angle between the first guide surface 231 and the guide rail 1, respectively cooperating with the first guide surface 231 and the guide rail 1, which can prevent the drive assembly 24 from moving to the working position A, thereby achieving self-locking of the drive mechanism 2.

[0051] In some embodiments, the triggering component 22 includes a connector 221 and a triggering part 222 disposed on the connector 221. The connector 221 is connected to the drive slider 23. The triggering part 222 cooperates with the second locking component 31 to allow the triggering component 22 and the drive slider 23 to move synchronously. When the drive mechanism 2 slides along the guide rail 1, it can drive the triggering part 222 to trigger the second locking component 31 to achieve bidirectional self-locking.

[0052] Furthermore, the connector 221 is covered outside the guide rail 1. The two opposite sides of the connector 221 are respectively provided with a first guide groove 2211 arranged along the guide direction. The two ends of the first pin 212 pass through the first guide groove 2211 on both sides respectively. The two ends of the first pin 212 are respectively connected to the drive assembly 24 with a first elastic member 211.

[0053] When the drive assembly 24 is in working position A, the first pin 212 is located at the end of the first guide groove 2211 near the motion mechanism 3, separated from the first guide surface 231, thus unlocking the drive mechanism 2. When the drive assembly 24 is in locked position B, the first pin 212 is located at the end of the first guide groove 2211 away from the motion mechanism 3, and the first pin 212 is located within the angle formed by the first guide surface 231 and the guide rail 1. The first elastic member 211 provides the first pin 212 with an elastic force to engage with the first guide surface 231, thereby achieving self-locking of the drive mechanism 2.

[0054] Preferably, the connector 221 is provided with a limiting port 2212, and the drive component 24 cooperates with the limiting port 2212. The limiting port 2212 limits the range of movement of the drive component 24 to achieve locking and unlocking of the first locking component 21. When the drive component 24 is in working position A near the end of the limiting port 2212 that is close to the motion mechanism 3, both the drive mechanism 2 and the motion mechanism 3 can move normally. When the drive component 24 is in locked position B away from the end of the limiting port 2212 that is far from the motion mechanism 3, both the drive mechanism 2 and the motion mechanism 3 are locked.

[0055] Combination Figure 1 , 4 As shown in Figure 5, in some embodiments, the second locking component 31 includes a self-locking base 311 and a driving member 312; the self-locking base 311 is slidably engaged with the guide rail 1, and the driving member 312 is rotatably mounted on the self-locking base 311 between the self-locking position C and the unlocking position D. The triggering part 222 of the triggering component 22 abuts against the driving member 312, driving the driving member 312 to rotate to the self-locking position C, so that the second locking component 31 locks the motion mechanism 3 bidirectionally relative to the guide rail 1.

[0056] Furthermore, in this embodiment, the second locking component 31 further includes a second pin 313, a third pin 314, a second elastic element 315, and a third elastic element 316. The self-locking base 311 is provided with a second guide groove 3111, a second guide surface 3112, and a third guide surface 3113. The second guide groove 3111 extends along the guiding direction of the guide rail 1. The second guide surface 3112 and the third guide surface 3113 each form an angle with the guide rail 1, and the openings of the angles face away from each other, facilitating the second pin 313 and the third pin 314 to abut against each other from both ends of the self-locking base 311 for self-locking. Of course, the openings of the two angles can also face each other, as long as the bidirectional movement of the self-locking base 311 can be locked.

[0057] Preferably, the second pin 313 passes through the second guide groove 3111, which can limit the range of motion of the second pin 313. The second pin 313 is also located within the angle formed by the second guide surface 3112 and the guide rail 1. When it moves close to the second guide surface 3112, it locks the self-locking base 311.

[0058] Furthermore, the third pin 314 is positioned within the angle formed by the third guide surface 3113 and the guide rail 1, and the third elastic element 316 connects the second pin 313 and the third pin 314, providing elastic force for the second pin 313 and the third pin 314 to move closer together.

[0059] When the drive member 312 is in the self-locking position C, the drive member 312 is released from the second pin 313, and the third elastic member 316 provides elastic force for the second pin 313 and the third pin 314 to abut against the second guide surface 3112 and the third guide surface 3113 respectively, thereby realizing bidirectional self-locking.

[0060] When the trigger component 22 moves toward the motion mechanism 3, the drive component 312 rotates to the unlock position D following the movement of the trigger component 22 under the drive of the second elastic member 315. The rotation of the drive component 312 simultaneously causes the second pin 313 to separate from the second guide surface 3112, allowing the drive mechanism 2 to drive the motion mechanism 3 to move.

[0061] Preferably, after the drive component 312 rotates following the movement of the trigger component 22, the drive slider 23 abuts against the self-locking base 311, which facilitates the control of the distance between the drive mechanism 2 and the motion mechanism 3.

[0062] The connector 221 of the trigger component 22 is provided with a third guide groove 2213. The third guide groove 2213 extends along the guide direction of the guide rail 1. The third pin 314 is engaged in the third guide groove 2213, allowing the third pin 314 to move along the third guide groove 2213, thereby guiding and positioning the movement direction of the third pin 314.

[0063] The motion mechanism 3 also includes a first slider 33 and a second slider 34 for mounting the self-locking base 311. The first slider 33 and the second slider 34 are spaced apart on the guide rail 1 along the guide direction. The self-locking base 311 is connected between the first slider 33 and the second slider 34, which makes the movement of the self-locking base 311 more stable and also facilitates the expansion and installation of other structures.

[0064] Preferably, in order to achieve a more balanced force distribution, the second locking component 31 includes two driving members 312, two second elastic members 315, and two third elastic members 316. The two driving members 312 are respectively rotatably disposed on two opposite sides of the self-locking base 311. In this embodiment, the trigger part 222 is columnar and extends to both sides of the connector 221, which can apply force to the two driving members 312 respectively.

[0065] In addition, two second elastic members 315 are located on both sides of the connector 221 and are connected to the driving members 312 on both sides respectively. Two third elastic members 316 are respectively arranged on the two opposite sides of the self-locking base 311 and are connected to the ends of the second pin 313 and the third pin 314 on the side where they are located. The movement of the two ends of the second pin 313 and the third pin 314 is more balanced, and the locking and unlocking are more stable.

[0066] In some embodiments, the drive member 312 includes a laterally extending first drive portion 3121 and a second drive portion 3122. The first drive portion 3121 is abutted by the trigger portion 222 of the trigger assembly 22, and the second drive portion 3122 is used to drive the second pin 313 to separate from the second guide surface 3112. A second elastic member 315 is connected to the second drive portion 3122. When the trigger portion 222 applies force to the first drive portion 3121 in the direction of the drive mechanism 2, it drives the drive member 312 to rotate to the self-locking position C. When the trigger portion 222 stops applying force to the first drive portion 3121, the force applied by the second elastic member 315 to the second drive portion 3122 drives the drive member 312 to rotate to the unlocked position D.

[0067] Understandably, in other embodiments, when the drive member 312 rotates to the self-locking position C, it can also press against the friction plate, so that the friction plate is in close contact with the guide rail 1, thereby realizing the bidirectional self-locking of the motion mechanism 3.

[0068] Understandably, the above-mentioned technical features can be used in any combination without restriction.

[0069] The above description is merely an embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent structural or procedural transformations made based on the content of the present invention's specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of the present invention.
