As shown in fig. 2, the pushing trigger mechanism 21 includes a pushing trigger component and a pushing adjustment component.

The pushing triggering component extends towards the opposite side coupler 1; and when the car coupler 1 is automatically coupled, the opposite side car coupler 1 can push the pushing triggering assembly to move in the same direction. The push trigger assembly is driven by mechanical force of coupling of the coupler 1, the push force is further transmitted to the transmission mechanism 22 through the push trigger assembly, and meanwhile, the transmission mechanism 22 transmits the force to the pushing mechanism 23, so that the pushing mechanism 23 pushes the electric coupler out under the action of the push force. The opposite-side coupler 1 is a coupler body coupled to the coupler body of the vehicle.

Specifically, the pushing triggering component is arranged on the hook body and extends towards the opposite side coupler 1; when the car coupler is automatically coupled, the opposite car coupler 1 can push the pushing triggering assembly to move in the same direction; the pushing adjusting component comprises a first pushing adjusting piece, and one end of the first pushing adjusting piece is connected with the pushing triggering component.

By providing the guide cylinder 217, the pushing trigger mechanism 21 is prevented from swinging during movement, which results in unstable pushing process. Meanwhile, the first push trigger 2111 passes through the guide cylinder 217, so that the guide cylinder 217 serves as a guide during the movement of the first push trigger 211.

Further, in the present embodiment, the pushing trigger mechanisms 21 are symmetrically disposed on both sides of the coupler 1, that is, two pushing trigger mechanisms 21 are symmetrically disposed on both sides of the coupler 1. When the couplers 1 are coupled, the pushing triggering mechanisms 21 on the two couplers 1 are contacted, so that the pushing triggering mechanisms 21 on the two couplers 1 can be pushed mutually to realize triggering.

In summary, by adopting the above structure, when the coupling gap occurs at the upper end of the coupler 1, the gap can be shortened by releasing the first pushing adjusting piece 213, and meanwhile, the second pushing adjusting piece 214 plays a role in buffering the pushing force of the pushing triggering component, so that the pushing triggering mechanism 21 can stably transmit the mechanical force to the corresponding mechanism, and the electric coupler can be stably pushed out. Further, since the first pushing elastic member 2133 is in a disc spring structure, and the first pushing elastic member 2133 is disposed in the compression chamber 2134 between the first compression member 2131 and the second compression member 2132, the first pushing elastic member 2133 is in a pre-compressed state. Thus, when the coupler is coupled, the second push spring is first compressed by the mechanical pushing force, and when the second compression element 2132 is compressed to the maximum extent, i.e., the fourth push trigger 2122 is engaged with the stop flange 2154, the second compression element 2132 is no longer compressed. At this time, the pushing force of the electric coupler is kept unchanged, the two couplers 1 can continue to move relatively, the first pushing elastic piece 2133 starts to be stressed and compressed, and therefore the gap between the couplers is gradually reduced. Therefore, by adopting the structure, the coupling clearance between the couplers 1 can be compensated through the pushing adjusting assembly under the condition of keeping the compression force of the electric coupler unchanged. Therefore, the problem that the relative motion is generated between two mechanical car couplers due to overlarge gaps, and then the relative motion of the electric car couplers can be driven, and finally the electric car couplers are likely to be conducted and have poor sealing performance, so that the running safety of a train is influenced is solved.

Meanwhile, since the opposite coupler 1 can push the first push trigger 211, under the action of the first push trigger 211, the second push trigger 212 and the first push trigger 211 move in the same direction, that is, both move in a direction away from the opposite coupler 1. Because one end of the transmission mechanism 22 is connected with the second pushing trigger 212, the end of the transmission mechanism 22 moves along with the second pushing trigger 212; further, the pushing force is transmitted to the pushing mechanism 23 through the transmission mechanism 22, and the electric coupler is pushed out through the pushing mechanism 23, so that the mechanical driving force generated when the coupler 1 is automatically coupled is converted into the pushing force of the electric coupler. Therefore, by adopting the structure, the coupler 1 is not required to be provided with driving and controlling parts, so that the coupler 1 is simple in structure, low in operation and maintenance cost and effectively saved in space.

As shown in fig. 2, the transmission mechanism 22 includes a transmission member 221 and a rotation member 222. One end of the transmission member 221 is connected to the pushing trigger assembly, and the other end thereof is connected to the pushing mechanism 23. The rotating member 222 is disposed on the transmission member 221, and the transmission member 221 is rotatably connected to the hook body through the rotating member 222. In this embodiment, the transmission member 221 is preferably a rod-shaped structure, and the rotation member 222 is preferably a rotation shaft. Thus, when the first pushing trigger piece 211 is pushed by the opposite coupler 1, the second pushing trigger piece 212 and the first pushing trigger piece 211 move in the same direction, so that the second pushing trigger piece 212 further pushes one end of the transmission piece 221 to move in the same direction; due to the connection between the second push trigger 212 and the hook body through the rotating element 222, the other end of the transmission element 221 pushes the pushing mechanism 23 to move toward the opposite coupler 1, and the electric coupler is pushed out under the action of the pushing mechanism 23.

Further, the transmission member 221 includes a first transmission section and a second transmission section that are fixedly connected, and the length of the first transmission section is smaller than that of the second transmission section. One end of the first transmission section is connected with the pushing trigger mechanism piece, and the other end of the first transmission section is connected with the rotating piece 222; one end of the second transmission section is connected to the rotating member 222, and the other end is connected to the pushing mechanism. In other words, the transmission rod is divided into two sections, namely a first transmission section and a second transmission section, by the rotating part 222, the first transmission section is located above the second transmission section, namely, on the premise that the transmission part can realize transmission, the length of the second transmission section is designed into a reasonable length according to the length of the secondary positioning pin of the electric coupler, and the length of the second transmission section is longer than that of the first transmission section. Therefore, by adopting the structure, the stroke of the electric coupler is enlarged to a reasonable length, so that the guide length between the couplers 1 is increased; in other words, the short pushing distance of the pushing trigger mechanism 21 is converted into the long pushing distance of the electric coupler, so that the electric coupler can be further ensured to be accurately coupled.

As shown in fig. 2, the pushing mechanism 23 includes a pushing assembly, a guiding assembly, and a connecting member 27. One end of the pushing component is connected with the transmission mechanism 22; the other end is connected with the electric coupler. The guiding component is fixedly connected with the mechanical coupler 1, and the guiding component extends towards the coupler 1 on the opposite side. One end of the connecting member 27 is fixedly connected to the electrical coupler and the other end is slidably connected to the guide member.

Specifically, as shown in fig. 5, the pushing assembly includes a first pushing member 231, a second pushing member 232, a third pushing member 233, and a pushing pressure spring 234. One end of the first pushing member 231 is connected with the transmission mechanism 22; one end of the second pushing element 232 is connected with the electric coupler, the other end is arranged opposite to the first pushing element 231, and a horizontal gap M exists between the second pushing element 232 and the first pushing element 231₁(ii) a One end of the third pushing member 233 is connected with the first pushing member 231 in a sliding manner, and the other end thereof is fixedly connected with the second pushing member 232; one end of the pushing compression spring 234 is sleeved on the first pushing member 231, and the other end thereof is sleeved on the second pushing member 232. Wherein, under the pushing action of the transmission mechanism 22, the first pushing member 231 slides along the third pushing assembly toward the second pushing member 232, and along with the horizontal gap M between the first pushing member 231 and the second pushing assembly₁Gradually decreases so that the pushing compression spring 234 is gradually compressed.

In this embodiment, one end of the first pushing element 231 is provided with a second mounting element 28, the second mounting element 28 is provided with a second mounting groove, the second mounting groove is also provided with a connecting hole, the connecting hole is also provided with a pin shaft, the other end of the transmission mechanism 22 is provided with a second long circular hole, and the pin shaft penetrates through the second long circular hole, so that the end of the transmission mechanism 22 is rotatably connected with the pin shaft, and the transmission mechanism 22 is rotatably connected with the second mounting element 28. At the same time, the end of the transmission 22 is allowed to rotate more freely in the longitudinal direction by the provision of this second oblong hole. Therefore, the transmission piece 221 can transmit the pushing force to the pushing mechanism 23 more effectively, so that the pushing mechanism 23 pushes out the electric coupler. Further, the first pushing member 231 includes a first pushing seat and a first pushing rod, and the outer circumference size of the first pushing seat is larger than that of the pushing compression spring 234 and is used for limiting the pushing compression spring 234; the outer diameter of the first pushing rod is slightly smaller than the cavity of the pushing compression spring 234, so that one end of the pushing compression spring 234 is sleeved on the first pushing rod.

It should be noted that the first oblong hole and the second oblong hole in the transmission mechanism 22 may be designed according to actual needs, and only the first oblong hole or the second oblong hole may be provided, or both may be present.

One end of the second pushing member 232 is connected to the electrical coupler, and the other end is disposed opposite to the first pushing member 231. Further, the second pushing member 232 includes a second pushing seat and a second pushing rod; the second pushing base is connected with the electric coupler and is used for limiting and pushing the pressure spring 234, the second pushing rod is arranged opposite to the first pushing rod, and the second pushing rod extends towards the first pushing rod. In this embodiment, a gap M exists between the second push rod and the first push rod in the horizontal direction₁And the outer diameter of the second pushing rod is slightly smaller than the cavity of the pushing compression spring 234, so that the other end of the pushing compression spring 234 can be sleeved on the second pushing rod. By adopting the above structure, the pushing compression spring 234 can be compressed under the action of pushing force, and the maximum compression distance is M₁。

One end of the third pushing member 233 is slidably connected to the first pushing member 231; the other end of which is fixedly connected with the second pushing member 232. In this embodiment, the third pushing member 233 is a rod-shaped structure, and when the first pushing member 231 receives a pushing force, the first pushing member 231 can slide toward the second pushing member 232 along the third pushing member 233, so as to play a guiding role, and the pushing pressure spring 234 can be more stable in a compression process.

By adopting the structure, the transmission mechanism 22 transmits the pushing force to the pushing mechanism 23, so that the pushing mechanism 23 pushes the electric coupler to move towards the position close to the opposite side coupler 1, and the pushing of the electric coupler is realized. However, a certain gap usually exists between the coupled couplers 1, and due to the arrangement of the pushing compression spring 234, the pushing compression spring 234 can be in a compressed state, so that the coupling gap between the couplers 1 can be compensated, and the good sealing performance and the conducting performance of the electric coupler are ensured.

The guide assembly comprises a hanger 24, a guide block 25, and a guide bar 26.

The hanger 24 is fixed on the mechanical coupler 1, and the guide block 25 is fixedly arranged on the hanger 24; and the guide block 25 is provided with a guide hole facing the other hook body on the opposite side. The guide rod 26 is fixedly arranged in the guide hole, the guide rod 26 is connected with the connecting piece 27 in a sliding mode, and the connecting piece 27 is fixedly arranged on the electric coupler. The connection member 27 of the present embodiment includes a first connection portion 271 and a second connection portion 272, and the first connection portion 271 is perpendicular to the second connection portion 272. The first connecting portion 271 is vertically and tightly fixed to a side end surface of the electrical coupler, so that the connecting member 27 can be stably disposed on the electrical coupler. The second connecting portion 272 is horizontally and closely attached to the upper end surface of the electric coupler, and the second connecting portion 272 is provided with a connecting through hole through which the guide bar 26 passes and is slidably connected to the second connecting portion 272.

Further, a limiting block 29 is further arranged on the upper end face of the electric coupler, the limiting block 29 is arranged opposite to the second connecting portion 272, a through hole is formed in the limiting block 29, and the guide rod 26 penetrates through the through hole and is connected with the limiting block 29 in a sliding mode. In other words, the stopper 29 is disposed near one end of the opposite coupler 1 and connected to the guide block 25, i.e., the stopper 29 is disposed at the front edge end of the electric coupler; one end of the guide rod 26 is slidably connected to the second connecting portion, and the other end thereof is slidably connected to the stopper 29. Since the stopper 29 is connected to the guide block 25, the stopper 29 prevents the electric coupler from moving backward by the mechanical pushing force. Meanwhile, by adopting the structure, the electric coupler slides along the extending direction of the guide rod 26 in the pushing-out process, so that the guide rod 26 plays a role in guiding the electric coupler, the stability of the electric coupler in the pushing-out process is ensured, and the swinging of the electric coupler in the pushing-out process is avoided.

As shown in fig. 2, in order to ensure good protection of the electric coupler when the electric coupler is not coupled, the electric coupler generally has a protective cover structure, and before the electric coupler is coupled, the protective cover should be opened to realize the connection between the two electric couplers. In order to enable the electric coupler to realize automatic coupling more effectively and stably, a cover turning device 3 for the electric coupler is further arranged.

Specifically, the flip cover device 3 includes a flip cover trigger mechanism 31 and a flip cover push mechanism 32.

The flip-flop trigger mechanism 31 is arranged on the coupler body, and one end of the flip-flop trigger mechanism 31 extends towards the opposite coupler 1; and when the coupler 1 is automatically coupled, the opposite coupler 1 can push the flip-flop trigger mechanism 31 to move in the same direction. The flip cover pushing mechanism 32 comprises a flip cover pushing member 321 and a flip cover guiding member 322, the flip cover pushing member 321 is connected with the flip cover triggering mechanism 31, and an arc-shaped guiding groove is arranged on the flip cover pushing member 321; one end of the flip cover guide 322 is fixedly connected with the protective cover 4 of the electric coupler, and the other end thereof is inserted into the arc-shaped guide groove. When the coupler 1 is automatically coupled, under the pushing action of the coupler 1 on the opposite side, the flip trigger mechanism 31 drives the flip pushing piece 321 to move, so that the flip guide piece 322 drives the protective cover 4 of the electric coupler to move along the arc-shaped guide groove, and the protective cover 4 of the electric coupler is opened.

More specifically, the flip-flop triggering mechanism 31 includes a flip-flop triggering elastic member, a first flip-flop triggering member 313, a second flip-flop triggering member 314, and a flip-flop triggering body 315.

The flip triggering elastic component comprises a flip triggering elastic shell 311 and a flip triggering elastic piece 312; a containing cavity 3111 is arranged in the flip-open cover triggering shell, and the flip-open cover triggering elastic piece 312 is arranged in the containing cavity 3111. Wherein, one end of the first flip-flop triggering component 313 penetrates into the accommodating chamber 3111 to be connected with the flip-flop triggering elastic component 312; one end of the second flip-flop triggering component 314 penetrates into the accommodating chamber 3111 to be connected with the flip-flop triggering elastic component 312; when the coupler 1 is automatically coupled, the first flip-flop triggering component 313 and the second flip-flop triggering component 314 interact under the pushing action of the opposite coupler 1, so that the flip-flop triggering elastic component 312 is compressed.

Further, the length extending direction of the accommodating chamber 3111 in the flip-flop elastic housing 311 is consistent with the pushing direction of the first flip-flop trigger mechanism 31, and the flip-flop elastic member 312, the first flip-flop trigger component 313 and the second flip-flop trigger component 314 are slidably disposed in the accommodating chamber 3111. In this embodiment, the flip triggering elastic housing 311 includes an elastic housing body 3112 and an elastic housing cover 3113. One end of the elastic housing body 3112 is provided with a through hole, through which the first flip triggering component 313 extends into the accommodating chamber 3111; the other end of the elastic case body 3112 is provided with an opening facing the second flip trigger assembly 314. Elastic housing cover 3113 joint is in elastic housing body 3112's opening part, and is provided with the through-hole on elastic housing cover 3113, makes second flip trigger component 314 stretch into in holding cavity 3111 through this through-hole.

In this embodiment, the elastic case body 3112 is preferably a cylindrical structure, and the accommodation chamber 3111 is a cylindrical structure. Further, the elastic case cover 3113 includes a first case cover portion and a second case cover portion. A stepped structure is formed between the first case cover portion and the second case cover portion, so that the elastic case cover 3113 can be clamped at an opening of the elastic case body 3112 to close the elastic case body 3112.

The first flip-flop trigger component 313 includes a first flip-flop trigger 3131 and a second flip-flop trigger 3132. In this embodiment, the first flip-flop triggering member 3131 is preferably a cylindrical rod-shaped structure, and one end of the first flip-flop triggering member 3131 extends toward the opposite-side coupler 1, and the other end thereof penetrates into the flip-flop triggering elastic housing 311 and extends toward the flip-flop triggering elastic member 312. Since the first flip-flop triggering part 3131 extends toward the opposite coupler 1, the first flip-flop triggering part 3131 can be coupled to the opposite coupler 1 when the coupler 1 is automatically coupled, so that the first flip-flop triggering part 3131 receives a certain pushing force. In this embodiment, the second flip-cover trigger 3132 is preferably a plate-shaped structure, the second flip-cover trigger 3132 is fixed on the first flip-cover trigger 3131, and the second flip-cover trigger 3132 is connected to the second flip-cover trigger 314. Thus, when the first flip-cover trigger 3131 is pushed, the second flip-cover trigger 3132 can move in the same direction as the first flip-cover trigger 3131, so as to push the second flip-cover trigger 314, and the flip-cover trigger elastic member 312 is compressed under the action of the second flip-cover trigger 314.

The second flip-flop trigger assembly 314 includes a third flip-flop trigger 3141 and a fourth flip-flop trigger 3142. In this embodiment, the third flip trigger 3141 is preferably a rod-shaped structure, and the fourth flip trigger 3142 is preferably a plate-shaped structure. Further, one end of the third flip trigger is connected to the flip pushing mechanism 32, and the other end thereof penetrates into the flip trigger elastic housing 311. The fourth flip-flop triggering member 3142 is fixedly disposed on the third flip-flop triggering member 3141, meanwhile, the fourth flip-flop triggering member 3142 is disposed between the second flip-flop triggering member 3132 and the flip-flop triggering elastic member 312, and two end faces of the fourth flip-flop triggering member 3142 are respectively connected to the second flip-flop triggering member 3132 and the flip-flop triggering elastic member 312. Thus, when the first flip-flop trigger 3131 receives a pushing force, the pushing force can be transmitted to the flip-flop trigger elastic member 312 through the fourth flip-flop trigger 3142, so that the flip-flop trigger elastic member 312 is compressed. Meanwhile, the third flip-flop triggering part 3141 transmits the pushing force to the flip-flop pushing mechanism 32, so that the flip-flop guiding part 322 drives the protective cover 4 of the electrical coupler to move along the arc-shaped guide groove under the action of the flip-flop pushing mechanism 32, thereby opening the protective cover 4 of the electrical coupler.

As shown in fig. 3 and 7, the flip pushing mechanism 32 includes a flip pushing member 321, a flip guide 322, and a rotating member 323. The flip cover pushing member 321 is connected to the flip cover triggering mechanism 31, one end of the flip cover guiding member 322 is fixedly connected to the protective cover 4 of the electrical coupler, and the other end of the flip cover guiding member is inserted into the arc-shaped guiding groove on the flip cover pushing member 321.

In this embodiment, the flip pushing member 321 includes a first flip pushing portion 3211 and a second flip pushing portion 3212. The first flip pushing part 3211 is connected to the third flip triggering member 3141 so that the third flip triggering member 3141 can transmit the pushing force to the flip pushing mechanism 32. The second flip pushing portion 3212 is preferably a plate-shaped structure, and the second flip pushing portion 3212 is provided with the arc-shaped guide grooves, which include a first guide groove 3213 and a second guide groove 3214. The first guide groove 3213 is horizontally disposed on the flip pushing member 321, one end of the second guide groove 3214 is connected to the first guide groove 3213, and the other end of the second guide groove 3214 is curved and extends downward, i.e., is curved in a direction away from the first flip pushing portion 3211, and the second guide groove 3214 is communicated with the first guide groove 3213, i.e., the horizontal plane of the second guide groove 3214 is lower than the horizontal plane of the first guide groove 3213. Meanwhile, in the present embodiment, the arc-shaped curve angle of the first guide groove 3213 needs to be obtained by a corresponding calculation method. In addition, the arc-shaped curve of the first guide groove 3213 may be changed according to actual conditions, processing difficulty, and the like.

In this embodiment, the flip cover guide 322 is preferably a rod-shaped structure, before the flip cover trigger mechanism 31 is triggered, the flip cover guide 322 is located in the second guide groove 3214, and after the flip cover trigger mechanism 31 is triggered, the flip cover guide 322 moves from the second guide groove 3214 to the first guide groove 3213. When the coupler 1 is automatically coupled, under the pushing action of the coupler 1 on the opposite side, the first flip-flop triggering element 3131 drives the flip-flop pushing mechanism 32 to move towards the position far away from the coupler 1 on the opposite side, that is, the second flip-flop pushing portion 3212 also moves towards the position far away from the coupler 1 on the opposite side, at this time, because the horizontal plane of the first guiding groove 3213 is higher than the horizontal plane of the second guiding groove 3214, and the second guiding groove 3214 is an arc-shaped structure, the horizontal movement of the flip-flop pushing element 321 is converted into the rotational movement of the protective cover 4 through the matching of the first guiding groove 3213, the second guiding groove 3214 and the flip-pushing element 322, that is, when the second flip-pushing portion 3212 moves linearly, the direction of the force applied by the arc-shaped guiding groove to the flip-pushing element 322 is perpendicular to the connecting line between the center of the rotating element 323 and the center of the flip-pushing element 322, the flip guide 322 and the rotator 323 are prevented from being damaged by the impact force. Meanwhile, the second guide groove 3214 functions in that after the protective cover 4 is opened, the flip guide 322 can move along the first guide groove 3213, so that the electrical coupler can move forward in the horizontal direction to realize pushing out of the electrical coupler, that is, after the protective cover is opened, the electrical coupler is pushed out, that is, along with the change of the distance between the couplers, the electrical coupler can sequentially move. In other words, the distance between the two couplers 1 is converted into the opening action of the protective covers 4 in a one-to-one correspondence manner, and finally the protective covers 4 are opened, and the protective covers 4 pass through the first guide grooves 3213 after being opened, so that the electric coupler can be stably pushed out. The problem that in the prior art, a flip device cannot be applied to application of realizing sequential actions of the electric couplers depending on distance changes among the couplers is solved.

Further, a flip trigger 315 is disposed on the hook, the flip trigger 315 is disposed corresponding to the flip trigger 31, that is, the flip trigger 315 and the flip trigger 31 are disposed on two sides of the hook respectively. When the coupler 1 is coupled, the flip-flop triggering body 315 on the coupler 1 on the opposite side contacts with the first flip-flop triggering component 313 in the flip-flop triggering mechanism 31, so as to trigger the flip-flop device 3 to open the protective cover 4. By providing the flip trigger 315, the flip trigger mechanism 31 can be triggered more stably, so that the flip device 3 can realize the flip function more stably.

Therefore, the protective cover 4 of the electric coupler can realize opening action by using mechanical driving force when the coupler 1 is coupled by adopting the structure, so that the electric coupler is not required to be relied on; namely before the electric coupler is pushed out, the protective cover 4 can be opened independently. When the coupler 1 is disengaged, the protective cover 4 can be automatically closed due to the disappearance of the pushing force. Therefore, the electric couplers can sequentially act according to the change of the distance between the couplers. Thus, the distance between the flip-flop trigger 31 and the opposite coupler 1 in the flip device 3 can be adjusted. Therefore, the problem that the flip device 3 in the prior art cannot be applied to the application of realizing the sequential action of the electric coupler by means of the distance change between the couplers 1 is solved.

In this embodiment, the length of the extending connection surface of the flip-open trigger mechanism 31 is greater than the length of the extending connection surface of the pushing trigger mechanism 21, so that when the coupler 1 is coupled, the opposite coupler 1 is first connected to the flip-open trigger mechanism 31, and thrust is generated to the flip-open trigger mechanism 31, so that the flip-open trigger mechanism 31 drives the protective cover 4 to open. As the two couplers 1 further approach, the opposite coupler 1 starts to push the pushing trigger mechanism 21, so that the pushing mechanism 23 drives the electric coupler to move toward the direction approaching the opposite coupler 1 under the action of the transmission mechanism 22, thereby realizing the pushing of the electric coupler.

In other words, the length of the extending connecting plane of the flip-open trigger 31 is greater than the length of the extending connecting plane of the push trigger 21, so that the protecting cover 4 is opened before the electric coupler is pushed out. Therefore, the protective cover 4 is not limited by the length of the good guide part of the coupler 1 when being opened, so that the coupler 1 with short guide length can be safely opened under the action of mechanical drive, the electric coupler can be accurately pushed out, and the electric coupler can be accurately linked. The technical problem that the automatic coupling coupler 1 with short guide length in the prior art cannot realize accurate coupling of an electric coupler through mechanical driving is solved.

Meanwhile, two ends of the hook body are respectively provided with a secondary positioning pin 7 and a secondary positioning sleeve 8. In this embodiment, the secondary positioning pin 7 and the secondary positioning sleeve 8 are disposed on the coupler body of the electric coupler. Specifically, the secondary positioning pin 7 is arranged corresponding to the secondary positioning sleeve 8 on the coupler body of the opposite side electric coupler, and the secondary positioning sleeve 8 is arranged corresponding to the secondary positioning pin 7 on the coupler body of the opposite side electric coupler. Through the mutual matching between the electric pushing device and the cover turning device, the electric coupler can have a good guide structure when the coupler 1 is automatically coupled; therefore, the secondary positioning pin 7 can be accurately inserted into the secondary positioning sleeve 8 on the coupler body of the opposite side electric coupler; meanwhile, the secondary positioning pin 7 on the hook body of the opposite side electric coupler can be accurately inserted into the secondary positioning sleeve 8, so that the precise matching of the inner contact pin and the inner jack of the electric coupler is ensured.

In summary, the length of the pushing trigger mechanism extending out of the connecting line is set to L1, the length of the guide surface 9 of the convex pile 5 is set to L2, and the length of the flip trigger mechanism extending out of the connecting line is set to L3. Meanwhile, the transmission mechanism 22 is arranged, so that the stroke of the electric coupler is prolonged, the guide length between the couplers 1 is increased, and the electric coupler has enough guide length when being linked. By the arrangement of the structure, when the coupler 1 is coupled, the convex pile 5 firstly enters the concave pile 6, so that a better guiding effect is achieved in the coupling process, and on the basis, the flip triggering mechanism 31 moves successively to open the protective cover 4; finally, the pushing trigger mechanism 21 is triggered, and the electric coupler is pushed out under the action of the pushing trigger mechanism 21. The relation between the L3 and the L1 value is designed according to the length of the secondary positioning pin of the electric coupler and the related dimension of the electric coupler, so that the protective cover 4 is opened before the electric coupler is pushed out, and the phenomenon that the protective cover 4 cannot be opened due to short guide length of the coupler is avoided. Meanwhile, as the L2 is greater than the L1, the electric coupler is provided with good guide and enough guide length when being pushed out, so that the secondary positioning sleeve and the secondary positioning pin can be accurately connected, and the contact pin and the jack between the electric couplers can be accurately connected. The technical problem that the automatic coupling coupler 1 with short guide length in the prior art cannot realize accurate coupling of an electric coupler through mechanical driving is solved.

The invention also provides a car coupler 1 which comprises a coupler body, wherein the coupler body is provided with the electric car coupler pushing device.

Meanwhile, the coupler 1 comprises a coupler body, the coupler body comprises an electric coupler body, and a protective cover 4 is arranged on the electric coupler body; a flip cover device 3 is arranged on one side of the protective cover 4, the flip cover device 3 comprises a flip cover trigger mechanism 31 and a flip cover pushing mechanism 32, and the flip cover trigger mechanism 31 extends towards the opposite side coupler 1; when the coupler 1 is automatically coupled, the opposite coupler 1 can push the flip-flop trigger mechanism 31 to move synchronously; one end of the flip pushing mechanism 32 is connected to the flip triggering mechanism 31, and the other end is connected to the protecting cover 4. Wherein, when coupling 1 is automatic to be linked, make under offside coupling 1 pushing action flip trigger mechanism 31 drives flip pushing mechanism 32 and promotes protective cover 4 moves, realizes opening of protective cover 4.

In this embodiment, the length L3 of the flip trigger mechanism 31 extending out of the connecting plane is greater than the length L1 of the push trigger mechanism 21 extending out of the connecting plane; when the coupler 1 is coupled, the flip-flop trigger mechanism 31 is triggered by the opposite coupler 1 before the pushing trigger mechanism 21.

The invention also provides a working method of the automatic coupling coupler 1, which comprises the following steps:

s1: when the two car couplers 1 are oppositely connected,

when two car couplers 1 run to a distance d₁When the convex pile 5 enters the concave pile 6; the opposite side coupler 1 pushes the flip cover triggering mechanism 31 to move, and the flip cover triggering mechanism 31 drives the protective cover 4 to open;

specifically, when two couplers 1 are driven to a distance d₁When the first flip-flop triggering part 3131 contacts with the flip-flop triggering body 315 arranged on the opposite coupler 1, triggering is started, that is, the first flip-flop triggering part 3131 is pushed; because the length of the convex cone is greater than the length of the extending connection surface of the first flip-flop triggering piece 3131, the convex cone enters the concave cone at this time, the convex cone and the concave cone have a certain guiding function, and the electric coupler cannot move backwards under the action of the limiting block 273 on the connecting piece 27 at this time. Under the pushing of the opposite-side coupler 1, the first flip-flop triggering element 3131 drives the flip-flop pushing mechanism 32 to move towards the position far away from the opposite-side coupler 1, that is, the second flip-flop pushing portion 3212 also moves towards the position far away from the opposite-side coupler 1, at this time, the second guide groove 3214 is matched with the flip-flop guide 322, and the guide groove moves to drive the flip-flop guide 322 to rotate counterclockwise around the rotating element 323 until the uncovering action is completed.

S2: when two couplers (1) continue to run to a distance d₂During the process, the maximum diameter position of the outer peripheral surface of the convex cone 5 enters the concave cone 6, namely the guide surface 9 of the convex cone 5 enters the concave cone 6, the opposite side coupler 1 pushes the pushing trigger mechanism 21, the pushing trigger mechanism 21 drives the transmission mechanism 22 to push the pushing mechanism 23, so that the pushing mechanism 23 pushes the electric coupler to move towards the direction close to the opposite side coupler 1, and the electric coupler is pushed out.

Specifically, when the two couplers 1 continue to drive to a distance d₂At the moment, the guide surface 9 of the convex cone 5 enters the concave cone 6, the mechanical coupler has good guide, and the two couplers 1 push the trigger mechanism 21 to start triggering. I.e. the first push trigger 211 is pushed by the opposite coupler 1, while the first push trigger 211 and the second push trigger 211 are pushed by the opposite coupler 1The push trigger 212 retracts; meanwhile, the second pushing trigger 212 transmits the pushing force to the transmission member 221, and the transmission member 221 starts to rotate around the rotation member 222, so as to drive the pushing assembly to push the electric coupler to move along the guiding assembly toward the opposite coupler 1. The electric coupler continues to move forwards, and the secondary positioning pin 7 and the secondary positioning sleeve 8 start to be matched, so that the electric coupler is accurately positioned.

S3: when two couplers (1) continue to run to a distance d₃And when the pushing trigger component pushes the pushing adjusting component, the pushing adjusting component is compressed, and the coupling clearance of the coupler 1 is compensated.

Specifically, when the two couplers 1 continue to drive to a distance d₃At this time, the second pushing trigger 212 reaches the position of the limiting flange 2154, the pushing trigger 21, the pushing mechanism 23, and the transmission mechanism 22 all stop moving, and the first pushing adjuster 213 starts to be compressed until the mechanical coupling is completed. By adopting the method, when the coupling gap exists between the first pushing triggering parts 211 of the two mechanical couplers 1 due to the coupling gap between the two mechanical couplers 1, the first pushing adjusting part 213 can supplement the gap, and meanwhile, the compression force of the electric coupler can be kept unchanged.

For a more clear description of the invention, the following description will be made of the installation process of the invention by taking the embodiment shown in fig. 1 to 7 as an example:

when two car couplers 1 run to a distance d₁During the process, because the length of the extending fine-grained surface of the flip-open cover trigger mechanism 31 is greater than the length of the extending fine-grained surface of the push trigger mechanism 21, when the coupler 1 is coupled, the opposite coupler 1 is firstly connected with the flip-open cover trigger mechanism 31, and generates thrust to the flip-open cover trigger mechanism 31, so that the flip-open cover trigger mechanism 31 drives the protective cover 4 to open. Specifically, at this time, since the length of the male taper 5 is greater than the length of the first flip-flop 3131 extending out of the connection surface, the male taper 5 enters the female taper 6, the male taper 5 and the female taper 6 have a certain guiding function, and the electric coupler cannot move backward under the action of the stopper 273 on the connection member 27. Under the push of the opposite coupler 1, the first flip-open trigger 3131 pushes the second flip-open triggerThe cover trigger 3132 moves while pushing the flip-cap trigger elastic member 312 to compress, and the second flip-cap trigger 3132 further pushes the flip-cap pushing mechanism 32 to move toward the position away from the opposite-side coupler 1, at this time, due to the cooperation of the second guide groove 3214 and the flip-cap guide 322, the guide groove moves to drive the flip-cap guide 322 to rotate counterclockwise around the rotating member 323, thereby completing the uncovering operation of the protective cover 4. Because the electric coupler is still in a non-pushed state at the moment, the protective covers 4 on the two electric couplers have sufficient space for opening, so that the protective covers 4 of the electric coupler can be safely opened under the action of mechanical drive of the automatic coupling coupler 1 with short guide length.

When two couplers (1) continue to run to a distance d₂At this time, the guide surface 9 of the convex cone 5 enters the concave cone 6, the mechanical coupler 1 has good guidance, and the two couplers 1 push the trigger mechanism 21 to start triggering. That is, the first push trigger 211 is pushed by the opposite coupler 1, so that the second push adjuster 214 is compressed first, and then the pushing force increases, and the second push adjuster 214 continues to be compressed. Specifically, the first push trigger 211 transmits the pushing force to the first compression member 2131, the first push elastic member 2133, the second compression member 2132, the second push trigger 212, and the second push elastic member 214 in sequence. In the process, the second pushing elastic member 214 is compressed, the second pushing trigger member 212 transmits the pushing force to the transmission member 221, the transmission member 221 starts to rotate around the rotating member 222, and the pushing member is driven to push the electric coupler to move along the guiding member toward the opposite coupler 1. The electric coupler continues to move forwards, and the secondary positioning pin 7 and the secondary positioning sleeve 8 start to be matched, so that the electric coupler is accurately positioned.

Specifically, when the two couplers 1 continue to drive to a distance d₃At this time, the second pushing trigger 212 reaches the position of the limit flange 2154, at this time, the pushing mechanism 23 and the transmission mechanism 22 both stop moving, that is, the pushing force of the electric coupler remains unchanged, and at this time, the first pushing adjusting part 213 is still compressed under the action of the pushing force until the mechanical coupling is completed. Since the initial pre-pressure of the first push adjuster 213 is greater than the maximum compression force of the second push adjuster 214When the structure is adopted, when a coupling piece gap appears on the upper side of the mechanical coupler in the coupling operation process of the two couplers 1, the first pushing adjusting piece 213 can compensate the gap under the condition of keeping the compression force of the electric coupler unchanged, and if the structure is not adopted, the electric coupler can generate a larger gap due to the amplification effect of the transmission mechanism 22, so that the electric coupler is failed in connection. Therefore, by adopting the structure, the problem that the electrical coupler is unreliable in connection due to the fact that the gap of the upper side of the mechanical coupler is large in the operation process is solved.

In this embodiment, the predetermined boundary condition refers to a position and a closing angle β of a protective cover 4 of the electric coupler in the initial state₁And the opening angle beta of the electric coupler after being pushed in place₂。

It should be noted that the uncapping curve of the arc-shaped guide groove may be changed according to actual conditions, processing difficulty and the like, and is not limited to the above calculation method.

Based on the above, the invention has at least the following technical effects and advantages:

1. according to the invention, by arranging the electric coupler pushing device 2, the mechanical coupler coupling force is converted into the electric coupler pushing force, so that the electric coupler is pushed out without arranging driving and control parts, the automatic coupling coupler is simple in structure and low in operation and maintenance cost, and meanwhile, the space is effectively saved.

2. According to the invention, the electric coupler can be pushed out under the action of mechanical driving force by arranging the electric coupler pushing device, and meanwhile, the stroke of the electric coupler is prolonged by the transmission mechanism 22, so that the guide length between the couplers is increased, the couplers have enough guide length during coupling, and the electric coupler can be accurately coupled. Meanwhile, the stroke of the electric coupler is prolonged, so that the secondary positioning pin 7 and the secondary positioning sleeve 8 on the electric coupler can be accurately connected together. Further, the stroke of the electric coupler is prolonged, and the protective cover 4 of the electric coupler can be effectively opened. Therefore, by adopting the structure, the automatic coupling coupler 1 with short guide length is accurately coupled under the action of mechanical drive, and the technical problem that the automatic coupling coupler 1 with short guide length in the prior art cannot be accurately coupled through mechanical drive is solved.

3. According to the invention, the length of the extending connection surface of the flip-cover trigger mechanism 31 is larger than that of the pushing trigger mechanism 21, so that when the coupler 1 is coupled, the flip-cover trigger body 315 of the opposite coupler 1 is firstly connected with the flip-cover trigger mechanism 31 and generates thrust on the flip-cover trigger mechanism 31, the flip-cover trigger mechanism 31 drives the protective cover 4 to be opened firstly, and the pushing trigger mechanism 21 is triggered, so that the protective cover 4 of the electric coupler is opened before the electric coupler is pushed out, and the phenomenon that the protective cover 4 cannot be opened due to the short guiding length of the coupler 1 is avoided. Therefore, the opening action of the protective cover 4 of the electric coupler and the extending action of the electric coupler can be sequentially carried out according to the structure, namely, the action of the electric coupler is related to the distance between the couplers, and the electric coupler sequentially acts along with the change of the distance between the couplers 1.
