TECHNICAL FIELD

[0001] The present application relates to a train compartment, in particular to a moving car translation mechanism. BACKGROUND

[0002] A train compartment is disclosed in Chinese patent application CN118770295A, which comprises an upper compartment and a moving car arranged in the upper compartment. The moving car can be transferred between two parallel train compartments to realize the exchange of passengers in the two train compartments. SUMMARY

[0003] The purpose of the present application is to provide a translation mechanism for the moving car of the aforementioned train compartment.

[0004] The technical solution of the present application is to construct a translation mechanism for a moving car of a train, which comprises a track and a driving component arranged on the ground of an upper compartment of the train, and a matching component arranged at the bottom of the moving car.

[0005] The track comprises a pair of longitudinal rails, a pair of first transverse rails and a pair of second transverse rails. The matching component comprises at least four pairs of track wheels and passive locking devices. The track wheels can cooperate with the longitudinal rails, the first transverse rails and the second transverse rails.

[0006] The driving component comprises longitudinal driving devices arranged along one side of the longitudinal rails, first transverse driving devices arranged along both sides of the first transverse rails, and second transverse driving devices arranged along both sides of the second transverse rails. The longitudinal driving devices, the first transverse driving devices and the second transverse driving devices each comprise a matching lead screw and a sliding block, as well as a lead screw driving motor connected to the lead screw. The sliding block is provided with a driving locking device that cooperates with the passive locking device.

[0007] The driving locking device is a push rod, and the passive locking device is a push rod hole. The push rod can be inserted into and withdrawn from the push rod hole when it is lifted.

[0008] The driving locking device is an electromagnet, and the passive locking device is an iron sheet. The upper part of the sliding block is provided with a movable groove that accommodates the electromagnet. The lower part of the sliding block is a lead screw hole that cooperates with the lead screw. The cross section of the electromagnet is an I-shaped section with equal width above and below. The coil is arranged in a groove on the side of the I-shaped section. Within the upper and lower movement range of the electromagnet, the upper and lower ends of the electromagnet are matched with the movable groove.

[0009] In one embodiment, the longitudinal rails are divided into three sections, and the two sections at both ends are respectively connected to the first transverse rails and the second transverse rails. One of the first transverse driving devices and the second transverse driving devices is respectively located at the disconnected part of the longitudinal rails.

[0010] In one of the embodiments, a position detection device is further included, two parts of the position detection device are arranged on the movable car and the ground of the upper layer car respectively, or arranged on the movable car and the wall of the upper layer car respectively, so that the position detection device is triggered when the movable car reaches the designated position, and a position signal is sent.

[0011] In one of the embodiments, the two parts of the position detection device are a light emitting unit and a light receiving unit, such as a pair of laser emitter-receiver devices or a pair of infrared emitter-receiver devices.

[0012] The track wheels are evenly distributed in the advancing direction of the car, and at least three pairs of track wheels are located on the longitudinal rails when any pair of track wheels passes through the disconnection of the longitudinal rails.

[0013] In one of the embodiments, the distance between the two pairs of track wheels at the two ends is greater than or less than the distance between the two disconnections of the longitudinal rails, preventing the two pairs of track wheels from sinking into the disconnection of the longitudinal rails and causing one end of the movable car to sink.

[0014] Advantages and benefits of the present application: When the present application is applied to the train car described in the background art, the movable car can be connected and driven in two directions to achieve the purpose of quickly exchanging the movable car between two train cars. In the present application, at least three pairs of track wheels are stably supported on the longitudinal rails, which can ensure that the track wheels can pass through the disconnection of the longitudinal rails in the air, preventing being stuck or jolted. The electromagnetic iron and the iron sheet are connected in a movable manner, which has a large redundant connection space, and even if they are not completely aligned, they can still be connected, which is highly reliable.

Preferred embodiments of the invention are shown in the drawings. However, the invention can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete.

[0026] It should be noted that when a component is considered to be "set" on another component, it can be directly set on or connected to the other component, or there may be an intervening component at the same time.

[0027] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art. The terminology used in this specification is for descriptive purposes only and is not intended to limit the invention. Example 1

[0028] like Figures 1-4 As shown, a translation mechanism for a train movable car includes a track 1 and a drive component 2 installed on the floor a of the upper carriage of the train, and a cooperating component 3 installed at the bottom of the movable car b.

[0029] The track 1 includes a pair of longitudinal rails 11, a pair of first transverse rails 12, and a pair of second transverse rails 13. The mating component 3 includes four pairs of track wheels 31 that can change direction and a passive locking device 32. The track wheels 31 can be mated with the longitudinal rails 11, the first transverse rails 12, and the second transverse rails 13.

[0030] The driving component 2 includes a longitudinal driving device 21 arranged along one side of the longitudinal rail 11, a first transverse driving device 22 arranged along both sides of the first transverse rail 12, and a second transverse driving device 23 arranged along both sides of the second transverse rail 13. The longitudinal driving device 21, the first transverse driving device 22, and the second transverse driving device 23 each include a cooperating lead screw 24 and a slider 25, as well as a lead screw drive motor 26. The slider 25 is provided with an active locking device 27 that cooperates with the passive locking device 32.

[0031] The active locking device 27 is a push rod, and the passive locking device 32 is a push rod hole. The push rod can be inserted into and removed from the push rod hole when it is raised or lowered.

[0032] The longitudinal rail 11 is divided into three sections. The two sections at both ends are respectively connected to the first transverse rail 12 and the second transverse rail 13. One of the first transverse driving device 22 and the second transverse driving device 23 is located at the break point of the longitudinal rail. That is, the first transverse driving device includes two sets of lead screws, sliders and lead screw drive motors, which are located at both ends of the first section of the longitudinal rail. The second transverse driving device also includes two sets of lead screws, sliders and lead screw drive motors, which are located at both ends of the third section of the longitudinal rail. Example 2

[0033] like Figures 5-7 As shown, in this embodiment, the active locking device 27 is an electromagnet, the passive locking device 32 is an iron sheet, the upper part of the slider 25 is provided with a movable groove 251 to accommodate the electromagnet, the lower part of the slider 25 is a threaded hole 252 that cooperates with the lead screw 24, the cross-section of the iron core 271 of the electromagnet is an I-shape with equal width at the top and bottom, and the coil 272 is set in the groove on the side of the I-shape. Within the vertical travel range of the electromagnet, both the upper and lower ends of the electromagnet cooperate with the movable groove 251. Figure 7 State I is the intermediate process of the electromagnet's core 271 rising or falling; State II is the state after the electromagnet's core 271 has fallen, completely separated from the iron plate 32; State III is the state after the electromagnet's core 271 has risen, attracting the iron plate 32.

[0034] In the foregoing embodiment, the four pairs of track wheels 31 can be evenly distributed at the bottom of the movable car b, such as... Figure 8 As shown; alternatively, the distance L3 between two consecutive pairs of track wheels at both ends can be smaller than the distance L4 between the two breaks in the longitudinal rail, as shown. Figure 9 As shown; alternatively, the distance between two consecutive pairs of track wheels at both ends can be greater than the distance between the two breaks in the longitudinal rail, as long as it is ensured that the two pairs of track wheels do not appear at the breaks simultaneously. In this way, a pair of track wheels will not obstruct the moving car when passing through the breaks in the longitudinal rail.

[0035] In the embodiment 2, the matching connection between the electromagnet and the iron sheet is a movable connection, which has a large redundant connection space, and can reduce the precision requirement of the connection between the slider and the movable car, but the distance of the slider and the movable car may not be completely equal, so a positioning detection device is needed to accurately position the movable car. For example, a photoelectric sensing device is used to send a positioning signal when the movable car reaches the specified position. The commonly used positioning detection methods in the prior art include using infrared emitting tubes and infrared sensors, laser emitting and receiving sensors, etc. When the movable car reaches the corresponding position, the light emitted by the emitting head (light emitting unit) is just blocked, so that the receiving head (light receiving unit) cannot receive the signal and triggers further action.

[0036] The application process of the present application is shown in Figure 10 When the two cars c, d are connected in parallel, the distance L1 between them is less than the distance (L2) between the two passive locking devices (push rod holes or iron sheets) on the bottom of the movable car b corresponding to the same transverse driving device, so when the transverse driving device (slider and push rod or electromagnet f1 on the slider) of one car c drives the movable car e to the other car d, the slider and the push rod or electromagnet f1 of the car can only move to the edge of the car and not leave the car, and the slider and the push rod or electromagnet f2 on the slider of the other car d can connect the other push rod hole or iron sheet on the bottom of the movable car b at the edge of the car d, complete the power relay, and continue to drive the movable car b. Obviously, after completing the power relay, the push rod or electromagnet f1 should be retracted and disconnected from the movable car b before the movable car b leaves the car c. The transfer process of the movable car b is shown in Figure 10 The movable cars in the two train cars are simultaneously transferred to the opposite train cars, and the passenger transfer is completed.

[0037] Since the movable car is a long strip structure, only one driving mechanism (longitudinal driving device) is needed to keep the direction stable when moving along the long edge direction, and the driving mechanism can be arranged at the edge of the car in the direction of train advancement, avoiding the transverse track.

[0038] The embodiments described in the present application are only used to describe the preferred embodiments of the present application, and do not limit the concept and scope of the present application. Without departing from the design idea of the present application, various modifications and improvements of the technical solutions of the present application made by the engineering technicians in the field shall fall within the protection scope of the present application. The technical content of the present application claimed for protection has been fully recorded in the claims.
