[0002] The switch is a switching and locking device for turnouts. The switch is linked to the driving mechanism inside the contact assembly through a sliding locking block, and the driving mechanism then drives the contact type contact switch to turn on or off. The driving mechanism of the existing contact assembly usually stays against the locking block to achieve linkage, resulting in unstable movement of the locking block. Summary of the invention

[0003] An object of the present invention is to provide a driving mechanism for a contact assembly of a switch machine, which has a simple structure and high reliability.

[0004] Another object of the present invention is to provide a contact assembly for a switch machine, which has a simple structure and high reliability.

[0005] Another object of the present invention is to provide a switch machine, the contact assembly of which has a simple structure and high reliability.

[0006] The present invention provides a driving mechanism of a contact assembly of a switch machine, wherein the switch machine includes a contact type contact switch and a locking block, wherein the locking block can move between a pop-up position and a retracted position along a locking direction and its opposite direction. The driving mechanism includes a frame, a first driving member, a first elastic member and a second driving member. The first driving member is rotatably arranged on the frame around a rotation axis perpendicular to the locking direction, and the first driving member can rotate between a first trigger position and a second trigger position and drive the contact type contact switch to switch a switch state. One end of the first elastic member is fixed to the frame, and the other end acts on the first driving member and continuously applies an elastic force to the first driving member to rotate toward the first trigger position. The second driving member is movably arranged on the frame along the locking direction and its opposite direction and connected to the locking block, and the second driving member can synchronously move along the locking direction and its opposite direction under the drive of the locking block and push the first driving member to rotate between the first trigger position and the second trigger position. Among them, during the movement of the locking block from the pop-up position to the retracted position, the second driving member can move under the drive of the locking block, and can drive the first driving member to rotate from the first trigger position to the second trigger position, and during the movement of the locking block from the retracted position to the pop-up position, before the locking block reaches the pop-up position, the second driving member can continue to abut against the first driving member to keep it in the second trigger position.

[0007] The driving mechanism of the contact assembly of the switch machine of the present invention realizes the switch slow action when the locking block retreats and the switch fast action when the locking block pops out with a simple structure through the first driving member, the first elastic member and the second driving member. The first driving member continuously abuts against the second driving member and generates pressure under the action of the first elastic member. Under the support of the frame, the second driving member transmits force to the locking block only in the locking direction, which is conducive to the locking block popping out and improves stability.

[0008] In an exemplary embodiment of the driving mechanism, the first driving member includes a first driving part and a second driving part. The first driving part can rotate around the rotation axis and abut against the operating rod of the contact type contact switch to reciprocate. The second driving part can rotate around the rotation axis synchronously with the first driving part. The second driving member includes a driving block, a slider and a second elastic member. The driving block is movably arranged on the frame body and connected to the locking block along the locking direction and the opposite direction. When the first driving member is located at the first trigger position, the first driving part is located on the movement path of the driving block. The slider is arranged on the driving block and can move relative to the driving block along the locking direction and the opposite direction between a release position close to the second driving part and a compression position away from the second driving part. The second elastic member applies force to the driving block and the slider respectively, and continuously applies elastic force to the slider to make it move toward a release position. Wherein, during the movement of the locking block from the pop-up position to the retracted position along the locking direction, the slider can move relative to the driving block from its release position under the abutment of the second driving part, and the driving block can rotate against the second driving part and generate displacement in the opposite direction of the locking direction. When the first driving member moves to the second trigger position, the second elastic member drives the slider to move to the release position. When the locking block moves from the retracted position to the pop-up position, the slider at the release position can abut against the second driving part to prevent the first driving member from rotating to the first trigger position until the slider is out of contact with the second driving part.

[0009] In another exemplary embodiment of the driving mechanism, the driving block has a first abutting surface and a lifting inclined surface on one side along a lifting direction perpendicular to both the locking direction and the rotation axis, the first abutting surface is perpendicular to the lifting direction, the lifting inclined surface is parallel to the rotation axis and connected to the first abutting surface, and during the movement of the locking block from the pop-up position to the retracted position along the locking direction, the abutting position of the second driving portion and the driving block transitions from the inclined surface to the first abutting surface, and the first driving member is kept at the second triggering position. The slider has a second abutting surface flush with the first abutting surface on one side along the lifting direction, and during the movement of the locking block from the retracted position to the pop-up position, the abutting position of the second driving portion and the second driving member transitions from the first abutting surface to the second abutting surface, preventing the first driving member from rotating to the first triggering position.

[0010] In another schematic embodiment of the driving mechanism, the driving mechanism also includes a roller, which is rotatably disposed at the first driving end and has an axis parallel to the rotation axis. The driving block can drive the second driving part to rotate by leaning against the roller, and the friction between the driving block and the second driving part is reduced by the roller, thereby further improving stability.

[0011] In another schematic embodiment of the driving mechanism, the driving block is formed with a slide groove extending along the locking direction, the slider is arranged in the slide groove, and the second elastic member is a compression spring arranged in the slide groove along the locking direction, one end of which abuts against the inner wall of the slide groove, and the other end abuts against an end of the slider in the locking direction away from the second driving end.

[0012] In another schematic embodiment of the driving mechanism, the driving block is also formed with a long hole opened perpendicular to the locking direction and extending along the locking direction, and the slider also has a pin shaft that can slide in the long hole. The driving block limits the distance that the slider moves relative to the driving block through the long hole and the pin shaft.

[0013] In another exemplary embodiment of the driving mechanism, the first driving member further includes two spring sheets, which are arranged on the first driving part, and the first driving part can abut against the operating rod of the contact type contact switch through the spring sheets and make it reciprocate. The spring sheets can play a buffering role in the process of the first driving part abutting against the reciprocating motion of the operating rod to reduce the impact force and further improve the stability.

[0014] The present invention also provides a contact assembly of a switch machine, including a contact type contact switch and the above-mentioned driving mechanism, wherein a first driving member can rotate between a first trigger position and a second trigger position and drive the contact type contact switch to switch a switch state.

[0015] The present invention also provides a switch machine, comprising a locking block and a contact assembly as described above. The locking block can move between a pop-up position and a retracted position along a locking direction. The second drive member is movably arranged on the frame along the locking direction and the opposite direction. The second drive member is also connected to the locking block, and the second drive member can synchronously move along the locking direction and the opposite direction under the drive of the locking block and push the first drive member to rotate between a first trigger position and a second trigger position, wherein, during the movement of the locking block from the pop-up position to the retracted position, the second drive member can drive the first drive member to rotate from the first trigger position to the second trigger position, and during the movement of the locking block from the retracted position to the pop-up position, the second drive member can continuously abut against the first drive member to keep it in the second trigger position before the locking block reaches the pop-up position.

[0049] In order to have a clearer understanding of the technical features, purposes and effects of the invention, the specific embodiments of the present invention are now described with reference to the accompanying drawings. The same reference numerals in the drawings represent components with the same structure or similar structures but the same functions.

[0050] In this document, “exemplary” means “serving as an example, instance or illustration”, and any diagram or implementation described in this document as “exemplary” should not be interpreted as a more preferred or more advantageous technical solution.

[0051] To simplify the drawings, each drawing schematically shows only the parts related to the exemplary embodiment, which do not represent the actual structure of the product.

[0052] In this article, "first", "second", etc. are only used to distinguish each other, rather than to indicate their importance and order.

[0053] Figure 1 Schematic diagram of a driving mechanism for explaining an exemplary embodiment. Figure 1 The switch machine includes a contact type contact switch 60 and a locking block 70. The locking block 70 can move between a pop-up position and a retracted position along a locking direction X and its reverse direction. Figure 1 The middle locking block 70 is in the pop-up position, see Figure 6 The middle locking block 70 is located at the retracted position. The driving mechanism includes a frame 10 , a first driving member 20 , a first elastic member 30 and a second driving member 40 .

[0054] The first driving member 20 is rotatably disposed on the frame 10 around a rotation axis A perpendicular to the locking direction X. The first driving member 20 can rotate between a first trigger position and a second trigger position and drive the contact type contact switch 60 to switch a switch state. Figure 1 The first driving member 20 is located at the first triggering position, referring to Figure 6 The first driving member 20 is located at the second triggering position. Figure 2 2 is a schematic diagram for explaining the structure of the first driving member 20 of the driving mechanism. Figure 2 Combined with Figure 1 In the exemplary embodiment, the first driving member 20 includes a first driving portion 22 and a second driving portion 24. The first driving portion 22 can rotate around the rotation axis A. The operating rod 62 of the contact type contact switch 60 has a driving protrusion 64 extending along its radial direction. The first driving portion 22 can drive the operating rod 62 to reciprocate along its axial direction by abutting against the driving protrusion 64. The second driving portion 24 can rotate around the rotation axis A synchronously with the first driving portion 22.

[0055] The first elastic member 30 is a tension spring, one end of which is fixed to the frame 10 and the other end of which is fixed to the first driving member 20 , and continuously applies elastic force to the first driving member 20 to rotate it toward the first trigger position.

[0056] The second driving member 40 is movably disposed on the frame 10 along the locking direction X and the opposite direction thereof. The frame 10 can support the second driving member 40 in the lifting direction Y perpendicular to both the locking direction X and the rotation axis A. The second driving member 40 is also connected to the locking block 70, and the second driving member 40 can synchronously move along the locking direction X and the opposite direction thereof under the drive of the locking block 70 and push the first driving member 20 to rotate between the first trigger position and the second trigger position. Among them, under the elastic force of the first elastic member 30, the force of the first driving member 20 against the second driving member 40 during the rotation process can be partially offset by the frame 10, and only the force in the locking direction X is transmitted to the locking block 70.

[0057] Reference Figure 1 , Figure 5 and Figure 7 When the locking block 70 moves from the pop-up position to the retracted position, the second driving member 40 can move under the drive of the locking block 70 and can drive the first driving member 20 to rotate from the first trigger position to the second trigger position. Figure 6 When the locking block 70 moves from the retracted position to the pop-up position, the second driving member 40 can continuously abut against the first driving member 20 to keep it at the second triggering position before the locking block 70 reaches the pop-up position.

[0058] Figure 3It is a schematic diagram of the structure of the second driving member for explaining the driving mechanism. Figure 4 Schematic diagram of the structure of the first driving member and the second driving member of the driving mechanism. Figure 1 , Figure 3 and Figure 4 In the exemplary embodiment, specifically, the second driving member 40 includes a driving block 42, a slider 44 and a second elastic member 46. The driving block 42 is movably disposed on the frame 10 and connected to the locking block 70 along the locking direction X and the reverse direction thereof. When the first driving member 20 is located at the first trigger position, the first driving portion 22 is located on the moving path of the driving block 42. The driving block 42 is formed with a slide groove 43 extending along the locking direction X and a long hole 41 opened perpendicular to the locking direction X and extending along the locking direction X. The slider 44 is disposed in the slide groove 43 and can move relative to the driving block 42 along the locking direction X and the reverse direction thereof between a release position close to the second driving portion 24 and a compression position away from the second driving portion 24. The slider 44 has a pin 45 that can slide in the long hole 41. The pin 45 cooperates with the long hole 41 to determine the release position and compression position of the slider 44. The second elastic member 46 is a compression spring disposed in the slide slot 43 along the locking direction X, one end of which abuts against the inner wall of the slide slot 43, and the other end abuts against the slider 44. The second elastic member 46 applies force to the driving block 42 and the slider 44 respectively, and continuously applies elastic force to the slider 44 to make it move toward a release position, such as Figure 1 As shown in FIG. 4 , when the slider 44 is located at the release position, the pin 45 abuts against the inner wall of the right side of the long hole 41 .

[0059] Figure 5 is a schematic diagram for explaining the driving state of the driving mechanism when the locking block 70 moves from the pop-up position to the retracted position, referring to Figure 1 and Figure 5 When the locking block 70 moves from the pop-up position to the retracted position along the locking direction X, the slider 44 can move from its release position to the compressed position relative to the driving block 42 under the abutment of the second driving portion 24. At the same time, the driving block 42 can abut against the second driving portion 24 to rotate and the driving block 42 is displaced in the opposite direction of the locking direction X. In the exemplary embodiment, referring to Figure 3 ,and Figure 4The driving block 42 has a first abutting surface S1 and a lifting inclined surface S2 on one side along the lifting direction Y, the first abutting surface S1 is perpendicular to the lifting direction Y, and the lifting inclined surface S2 is parallel to the rotation axis A and connected to the first abutting surface S1. The slider 44 has a second abutting surface S3 on one side along the lifting direction Y that is flush with the first abutting surface S1. When the locking block 70 moves along the locking direction X with the driving block 42, the driving block 42 and the slider 44 contact the second driving part 24 at the same time. Under the abutment of the second driving part 24, the slider 44 compresses the second elastic member 46, and the slider 44 starts to move relative to the driving block 42 in the direction opposite to X from the release position, that is, the right side of the pin abutting the long hole. At the same time, the lifting inclined surface S2 of the driving block 42 abuts against and lifts the second driving part 24 along the lifting direction Y. The abutting position between the second driving portion 24 and the driving block 42 gradually transitions from the lifting inclined surface S2 to the first abutting surface S1 , and at this time, the first driving member 20 remains at the second triggering position.

[0060] Figure 6 Schematic diagram for explaining the driving state of the driving mechanism when the locking block 70 reaches the retracted position. Figure 5 and Figure 6 When the second driving part 24 is lifted to abut against the first abutting surface S1, the first driving member 20 moves to the second triggering position. Since the second abutting surface S3 is flush with the first abutting surface S1, at this time, the elastic restoring force of the second elastic member 46 can drive the slider 44 to move to its release position, and at this time, the second driving part 24 abuts against the first abutting surface S1 and the second abutting surface S3 at the same time.

[0061] Figure 7 is a schematic diagram for explaining the driving state of the driving mechanism when the locking block 70 moves from the retracted position to the pop-up position, referring to Figure 6 and Figure 7 , when the locking block 70 moves from the retracted position to the ejected position in the opposite direction of the locking direction X, the slider 44 can remain in its released position. The second driving portion 24 gradually breaks away from the contact with the driving block 42, and the abutment position between the second driving portion 24 and the second driving member 40 transitions from the first abutment surface S1 to the second abutment surface S3, and then the slider 44 continues to abut the second driving portion 24 and prevents the first driving member 20 from rotating to the first trigger position. When the slider 44 continues to move until the second driving portion 24 leaves the second abutment surface S3, the second driving portion 24 instantly loses support, and the first driving member 20 can quickly rotate and return to the first trigger position. Figure 1 The first trigger position is shown.

[0062] Reference Figure 1 and Figure 4In the exemplary embodiment, the driving mechanism further includes a roller 50, which is rotatably disposed on the second driving part 24 and whose axis is parallel to the rotation axis A. The driving block 42 can drive the second driving part 24 to rotate by abutting against the roller 50. The friction between the driving block 42 and the second driving part 24 is reduced by the roller 50, thereby further improving stability.

[0063] The driving mechanism of the contact assembly of the switch machine of the present invention realizes the switch slow movement when the locking block 70 retreats and the switch fast movement when the locking block 70 pops out with a simple structure through the first driving member 20, the first elastic member 30 and the second driving member 40. The first driving member 20 continuously abuts against the second driving member 40 under the action of the first elastic member 30, and the second driving member 40 is subjected to a continuously changing abutting force during the rotation of the first driving member 20. Since the second driving member 40 is arranged on the frame 10, under the support of the frame 10, the second driving member 40 only transmits force to the locking block 70 in the locking direction, so that the movement of the locking block 70 is more stable, which is conducive to the popping out of the locking block 70 and improves the stability of the overall function.

[0064] Reference Figure 1 and Figure 2 In the exemplary embodiment, the first driving member 20 further includes two spring sheets 28, which are arranged on both sides of the first driving portion 22 along a direction perpendicular to the rotation axis, and the driving protrusions 64 of the operating rod 62 are respectively located on both sides of the two spring sheets 28. The first driving portion 22 can drive the operating rod 62 to move by abutting against the driving protrusions 64 through the two spring sheets 28. The spring sheets 28 can play a buffering role in the reciprocating motion of the first driving portion 22 against the operating rod 62 to reduce the impact force and further improve the stability.

[0065] Reference Figure 1 and Figure 4 In the exemplary embodiment, the driving mechanism further includes a roller 50, which is rotatably disposed on the second driving portion 24 and whose axis is parallel to the rotation axis A. The driving block 42 can drive the second driving portion 24 to rotate by leaning against the roller 50. The friction between the driving block 42 and the second driving portion 24 is reduced by the roller 50, thereby further improving stability.

[0066] The present invention also provides a contact assembly of a switch machine, referring to Figure 1 The contact assembly includes a contact-type contact switch 60 and the above-mentioned driving mechanism. The first driving member 20 can rotate between a first trigger position and a second trigger position and drive the contact-type contact switch 60 to switch the switch state.

[0067] The present invention also provides a switch machine, referring to Figure 1The switch machine includes a locking block 70 and a contact assembly as described above. The locking block 70 is movably disposed on the frame 10 along the locking direction X and the opposite direction thereof. The second driving member 40 is also connected to the locking block 70, and the second driving member 40 can synchronously move along the locking direction X and the opposite direction thereof under the drive of the locking block 70 and push the first driving member 20 to rotate between the first trigger position and the second trigger position. In the process of the locking block 70 moving from the pop-up position to the retracted position, the second driving member 40 can drive the first driving member 20 to rotate from the first trigger position to the second trigger position, and in the process of the locking block 70 moving from the retracted position to the pop-up position, the second driving member 40 can continuously abut against the first driving member 20 to keep it in the second trigger position before the locking block 70 reaches the pop-up position.
