The embodiments described below with reference to the drawings are illustrative and intended to be illustrative of the invention and are not to be construed as limiting the invention.

The following disclosure provides many different embodiments, or examples, for implementing different features of the invention. To simplify the disclosure of the present invention, the components and arrangements of specific examples are described below. Of course, they are merely examples and are not intended to limit the present invention. Furthermore, the present invention may repeat reference numerals and/or letters in the various examples. This repetition is for the purpose of simplicity and clarity and does not in itself dictate a relationship between the various embodiments and/or configurations discussed. In addition, the present invention provides examples of various specific processes and materials, but one of ordinary skill in the art may recognize the applicability of other processes and/or the use of other materials.

Next, with reference to the drawings, a through passage 100, a train 1000, and a rail transit system 10000 according to an embodiment of the present invention are described.

Referring to fig. 1, a rail transit system 10000 may include a rail 2000 and a train 1000, wherein the train 1000 runs along the rail 2000, and the train 1000 may include a plurality of vehicle bodies 200 and a through passage 100 connected between two adjacent vehicle bodies 200, wherein the through passage 100 may be a through passage 100 according to any embodiment of the present invention described later. The rail transit system 10000 may be a subway system, a light rail system, or the like.

As shown in fig. 2 and 3, the through passage 100 may include: a first frame 1, a second frame 2 and a continuous knitting and releasing mechanism 3. Referring to fig. 4, the first frame 1 and the second frame 2 are disposed opposite to each other, that is, the first frame 1 and the second frame 2 are disposed facing each other. The coupling/decoupling mechanism 3 is for coupling and decoupling the first frame 1 and the second frame 2, and in other words, the first frame 1 and the second frame 2 can be coupled by operating the coupling/decoupling mechanism 3, and the first frame 1 and the second frame 2 can be decoupled by operating the coupling/decoupling mechanism 3.

As shown in fig. 5, the continuous knitting release mechanism 3 includes: the lock head 31, the lock seat 32 and the pushing device 33, with reference to fig. 6 and 7, the lock head 31 is fixed on the first frame 1, that is, the lock head 31 is installed on the first frame 1 and is stationary relative to the first frame 1. The lock base 32 is slidably provided on the second frame body 2, that is, the lock base 32 is mounted on the second frame body 2 and is slidable relative to the second frame body 2.

Referring to fig. 8, the pushing device 33 is also disposed on the second frame 2 and is used for pushing the lock seat 32 to slide toward the direction of the plug-fit locking with the lock head 31 (the first direction F1 shown in fig. 8). After the lock seat 32 is inserted and locked in place with the lock head 31, the first frame body 1 connected with the lock head 31 and the second frame body 2 connected with the lock seat 32 can be hung together.

Therefore, according to the through passage 100 of the embodiment of the present invention, the lock seat 32 is pushed by the pushing device 33, and the insertion locking of the lock seat 32 and the lock head 31 can be realized, so that the first frame 1 and the second frame 2 can be simply and effectively connected, and the connecting and releasing mechanism 3 has a simple structure and low cost. In addition, the train 1000 and the rail transit system 10000 according to the embodiment of the present invention have the through passage 100 according to the embodiment of the present invention, so that the advantages similar to those of the through passage 100 may be provided, and detailed description thereof is omitted.

In some embodiments of the present invention, as shown in fig. 4, a side surface of the second frame body 2 facing the first frame body 1 is provided with a second groove 22, and with reference to fig. 5 and 6, the lock seat 32 is provided with a slider 3211 which is matched with the second groove 22, and the slider 3211 is embedded in the second groove 22, so that the lock seat 32 slides along the second groove 22. Therefore, the sliding fit between the lock holder 32 and the second frame 2 can be simply and effectively realized, the assembly and the processing are convenient, and the assembly connection between the lock holder 32 and the second frame 2 can also be ensured through the fit between the second groove 22 and the slider 3211. It will be appreciated that the ends of the second groove 22 may have a break location to allow the slider 3211 to enter the second groove 22, i.e., the second groove 22 is not a closed loop around the second bezel 20 of the second frame 2.

It should be noted that the number of the second grooves 22 on the second frame 2 is not limited, and may be one or more, for example, in the examples shown in fig. 4 and 5, each lock seat 32 may be slidably engaged with two second grooves 22 through two sliders 3211, respectively, so as to improve the sliding reliability and stability of the lock seat 32. Of course, the present invention is not limited to this, and the lock seat 32 may also be slidably engaged with the second frame body 2 by other methods, for example, a slide rail may be installed on the second frame body 2, and the lock seat 32 may have a roller engaged with the slide rail, and so on, which will not be described herein.

In some embodiments of the present invention, as shown in fig. 2 and 3, the first frame body 1 may be a closed ring-shaped frame formed by joining a plurality of first frame edges 13 end to end, and the second frame body 2 may be a closed ring-shaped frame formed by joining a plurality of second frame edges 23 end to end, and in conjunction with fig. 2 and 3, each second frame edge 23 may have one or more lock seats 32, and each first frame edge 13 may have the same number of lock heads 31 as the number of lock seats 32, so that a plurality of hitching and unraveling mechanisms 3 run through the circumferential direction of the track 100, thereby improving the hitching reliability of the first frame body 1 and the second frame body 2.

In addition, the lock seat 32 can slide along the length direction of the corresponding second frame edge 23 (i.e. the lock seat 32 is disposed on which second frame edge 23, and can slide along the length direction of which second frame edge 23), so that the lock seat 32 can have a sufficient sliding space, thereby avoiding increasing the width of the second frame edge 23, and ensuring that the through passage 100 has a small volume, a light weight, and is convenient to process.

In some embodiments of the present invention, as shown in fig. 4, the first frame body 1 may have the same structure (i.e., the same shape and size) as the second frame body 2 and be arranged in an axisymmetric manner. Therefore, the processing and the assembly are convenient, and the universality is high. At this time, if the second frame 2 has the second groove 22, the first frame 1 has the first groove 11 having the same structure as the second groove 22, and referring to fig. 5 and 6, the locking head 31 can be fixedly connected to the first frame 1 by the mounting member 35 mounted to the first groove 11. Wherein, installed part 35 can be bolt etc. and the head of bolt can inlay and establish in first recess 11, and the pole portion and the tapered end 31 threaded connection of bolt. It will be appreciated that the end of the first recess 11 may have a break so that the head of the bolt can enter the first recess 11, so that the connection of the locking head 31 to the first frame 1 can be simply and effectively achieved, i.e. the first recess 11 is not a closed annular groove that surrounds the first rim 10 of the first frame 1 in a complete turn.

In some embodiments of the present invention, as shown in fig. 4, the first frame body 1 has a first sealing groove 12 which surrounds the first frame opening 10 of the first frame body 1 completely, the second frame body 2 has a second sealing groove 24 which surrounds the second frame opening 20 of the second frame body 2 completely, and the second sealing groove 24 is disposed opposite to the first sealing groove 12, so that a sealing member (not shown) may be filled in at least one of the first sealing groove 12 and the second sealing groove 24 to seal between the first frame body 1 and the second frame body 2. This can improve the sealing performance of the through passage 100. Of course, the present invention is not limited to this, and only one of the first frame body 1 and the second frame body 2 may have a seal groove.

In some embodiments of the present invention, as shown in fig. 5, one of the lock seat 32 and the lock cylinder 31 has a lock pin 313, and the other has a lock hole 3212, that is, when the lock seat 32 has the lock pin 313, the lock cylinder 31 has the lock hole 3212; when the lock base 32 has the lock hole 3212, the lock head 31 has a lock pin 313. Of course, the present invention is not limited thereto, and in other embodiments of the present invention, the lock seat 32 may also have the lock pin 313 and the lock hole 3212 at the same time, and in this case, the lock cylinder 31 may also have the lock pin 313 and the lock hole 3212 at the same time.

As shown in fig. 5, the lock pin 313 is adapted to be inserted into and locked with the lock hole 3212, that is, after the lock pin 313 penetrates into the lock hole 3212, the lock head 31 and the lock seat 32 can be locked and connected, and the extending direction of the lock pin 313 is the same as the sliding direction of the lock seat 32 (e.g., the direction F1-F2 shown in fig. 8) and perpendicular to the thickness direction of the second frame body 2, for example, when the lock seat 32 slides along the length direction of the corresponding second frame edge 23, the extending direction of the lock pin 313 is also the length direction of the corresponding first frame edge 13. Therefore, the locking and unlocking of the lock seat 32 and the lock head 31 can be simply and effectively realized, and the reliability of the coupling locking is ensured.

Here, it should be noted that the "thickness direction of the second frame 2" is described later, that is, an axial direction of the through passage 100, or a length direction of the train 1000 when the train 1000 travels along a straight line section of the track 2000, as shown in a third direction F3 in fig. 13.

Further, as shown in fig. 5, the cross-sectional area of one end of the lock pin 313 facing the lock hole 3212 may gradually decrease in a direction toward the lock hole 3212 (here, in a case where the lock pin 313 is not fitted in place with the lock hole 3212, the lock pin 313 is directed toward the lock hole 3212). Therefore, the lock pin 313 can conveniently enter the lock hole 3212, the assembly precision requirement is reduced, the production efficiency is improved, and the locking effectiveness of the lock head 31 and the lock seat 32 is improved.

For example, in the specific example shown in fig. 5, the lock head 31 may include a base portion 311, a rod portion 312 and a lock pin 313, the base portion 311 may be mounted on the first frame 1 through the mounting component 35, the rod portion 312 extends along a direction from the first frame 1 to the second frame 2, and two ends of the rod portion 312 are respectively connected to the base portion 311 and the lock pin 313, so as to ensure that the lock pin 313 can be close to the lock seat 32 mounted on the second frame 2, thereby facilitating alignment and locking between the lock pin 313 and the lock hole 3212, and reducing the processing difficulty of the lock seat 32.

In some embodiments of the present invention, as shown in fig. 8 and 9, the pushing device 33 may include a first mounting seat 331 and a rotating wheel 332, the first mounting seat 331 is fixed on the second frame body 2, that is, the first mounting seat 331 is mounted on the second frame body 2 and is stationary relative to the second frame body 2, the rotating wheel 332 is a cam (that is, the base circle of the outer contour is non-circular) or an eccentric (that is, the base circle of the outer contour is circular) and is rotatably connected to the first mounting seat 331, that is, the rotating wheel 332 is mounted on the first mounting seat 331 and is rotatable relative to the first mounting seat 331, and the rotating wheel 332 pushes the lock seat 32 to slide during rotation. Therefore, the lock holder 32 can be simply and effectively pushed to slide by rotating the rotating wheel 332, and the lock holder has the advantages of simple structure, quick response and low manufacturing cost. As shown in fig. 5 and 6, the connection between the first mounting seat 331 and the second housing 2 can refer to the connection between the lock head 31 and the first housing 1, which is not described herein again.

As shown in fig. 9, the outer peripheral surface of the rotor 332 may include a curved surface portion 3321 and a flat surface portion 3322, and when the flat surface portion 3322 is in surface contact with the lock holder 32, the lock holder 32 reaches a locking position where it is fitted to the lock cylinder 31. Therefore, when the lock base 32 reaches the locking position where the lock head 31 is inserted, that is, when the first frame body 1 and the second frame body 2 are hung together, the turning wheel 332 and the lock base 32 are in surface contact, so that the turning wheel 332 is prevented from continuing to turn or reversing due to other factors, for example, vibration of the train 1000, and the like, that is, the turning wheel 332 is prevented from turning away from the current angular position, the turning wheel 332 is ensured to be reliably stopped at the position where the lock base 32 and the lock head 31 are inserted and locked, the locking action is ensured to be reliable, and the stable hanging of the first frame body 1 and the second frame body 2 is ensured.

In the example shown in fig. 5 and 9, the latch base 32 may include a body portion 321, a link portion 322, and a force bearing portion 323, the link portion 322 being connected between the body portion 321 and the force bearing portion 323, and the force bearing portion 323 facing the pushing device 33 through a plane. From this, on the one hand, can draw close the distance between lock seat 32 and the thrust unit 33 through connecting rod portion 322, make things convenient for lock seat 32 and thrust unit 33 respectively with the erection joint of second framework 2, on the other hand, lock seat 32 can bear the driving force that thrust unit 33 applyed through having planar load portion 323, thereby make the atress of lock seat 32 more even, avoid lock seat 32 atress to concentrate, reduce the impaired risk of lock seat 32, and can improve the motion stationarity and the life of lock seat 32. In addition, the structural shape of the force bearing portion 323 is not limited, and for example, in the example shown in fig. 5, the force bearing portion 323 may be a flat plate shape, so that the force bearing portion is convenient to process and manufacture, and has low cost and good force bearing uniformity.

As shown in fig. 9, the rotating wheel 332 and the first mounting base 331 can be rotatably connected through a rotating shaft 333, and the rotating shaft 333 drives the rotating wheel 332 to rotate relative to the first mounting base 331 during rotation, that is, when the rotating shaft 333 is rotated, the rotating shaft 333 can drive the rotating wheel 332 to rotate synchronously therewith, for example, the rotating shaft 333 and the rotating wheel 332 can be matched through a key or a non-circular surface. Referring to fig. 10 and 11, an axial end 3331 of the rotating shaft 333 protrudes out of the second frame body 2 on the side away from the first frame body 1 and has a counterbore with a non-circular profile cross section or a non-circular cross section. Thus, the rotating shaft 333 can be rotated by the tool engaged with the axial end 3331, so as to rotate the rotating wheel 332, thereby pushing the lock seat 32 to slide toward the locking position.

As shown in fig. 9, the rotor 332 may have a first connection hole 3323, the first connection hole 3323 is spaced apart from the rotation axis of the rotor 332 (e.g., the central axis of the rotating shaft 333) and the second frame 2 has a second connection hole 21, and when the lock housing 32 reaches the locking position of being inserted into the lock head 31 (e.g., when the rotor 332 and the lock housing 32 are in surface contact as described above), that is, when the first frame 1 and the second frame 2 are coupled together, the first connection hole 3323 and the second connection hole 21 are aligned to be suitable for being connected by the connecting member 34.

Therefore, the turning wheel 332 can be further prevented from being turned away from the current position by other factors, so that the reliability of the connection between the first frame body 1 and the second frame body 2 is ensured, and the problem of drive clamping stagnation is avoided. In addition, in some embodiments of the present invention, one of the first coupling hole 3323 and the second coupling hole 21 may be a screw hole, and the coupling member 34 may be a screw or a bolt, so that the reliability of locking may be further improved.

Of course, the present invention is not limited thereto, for example, in other embodiments of the present invention, the pushing device 33 may also be other devices, such as a driving cylinder device, a rack and pinion mechanism, a worm and gear mechanism, etc., which are not described herein.

In some embodiments of the present invention, as shown in fig. 5, the hitching and knitting-releasing mechanism 3 may further include: and the unlocking device 36 is arranged on the second frame body 2 and is used for pushing the lock seat 32 to slide towards the direction of separating and unlocking from the lock head 31.
