A large-opening translation vehicle door structure is shown in figures 1-10 and comprises: a train body having a car 11 and a door 12; the pulling mechanism 2 is used for driving the vehicle door 12 to move along the parallel direction of the length direction of the carriage 11; the door pushing mechanism 3 is used for driving the vehicle door 12 to horizontally move along the vertical direction of the length direction of the carriage 11; and a support mechanism 4 for supporting the weight of the vehicle door 12.
Wherein, the pulling mechanism 2 comprises a pulling slide block 22 and a connecting plate 23; the pulling slide block 22 slides linearly on the carriage 11 along the length direction of the carriage 11; one end of the connecting plate 23 is fixedly connected with the pulling slide block 22, and the other end is fixedly connected with the top end of the vehicle door 12;
the door pushing mechanism 3 comprises a lifting block 31 and a rotating arm 32; the lifting block 31 is slidably mounted at the bottom of the carriage 11, and the lifting block 31 moves up and down; one end of the rotating arm 32 is hinged with the bottom end of the vehicle door 12, and the other end of the rotating arm freely droops; when the door 12 is closed, the freely hanging end of the rotating arm 32 abuts against the top end surface of the lifter 31;
the supporting mechanism 4 comprises a supporting guide rail 41, a supporting seat 42, a sliding rod 43 and a spring 44; the support guide rail 41 is fixedly connected with the bottom of the carriage 11; the support seat 42 slides on the support rail 41; one end of the sliding rod 43 is fixedly connected with the lower end of the vehicle door 12, and the other end is connected with the supporting seat 42 in a sliding manner and horizontally slides along the vertical direction of the length direction of the carriage 11; one end of the spring 44 is fixedly connected with the sliding rod 43, and the other end is fixedly connected with the supporting seat 42.
As shown in fig. 1, the movement locus of the door 12 is as follows: when the door 12 is closed, the door 12 moves to the position of the door frame on the compartment 11, and after the door 12 is aligned with the door frame, the door 12 moves outwards and horizontally along the length direction of the vertical compartment 11 to enter the door frame; when the door 12 is opened, the door 12 moves horizontally inwards along the length direction of the vertical compartment 11 to move out of the doorframe, and then moves to a position far away from the doorframe on the compartment 11 until the door 12 is completely staggered with the doorframe.
The working process of the vehicle door structure is as follows: when the door 12 is closed, the slider 22 is pulled to slide towards the door frame direction, the connecting plate 23 is driven to pull the door 12 to slide towards the door frame direction, when the door 12 is aligned with the door frame, the rotating arm 32 slides to the top end of the lifting block 31, at the moment, the slider 22 is pulled to stop sliding, the lifting block 31 rises upwards, abuts against the free end of the rotating arm 32 and pushes the rotating arm 32 to rotate, the other end of the rotating arm 32 pushes the bottom end of the door 12 to enter the door frame and keeps thrust, the connecting plate 23 at the top end generates elastic deformation along with the bottom end, the top end of the door 12 also enters the door frame along with the bottom end, the door closing action is completed, and meanwhile, the sliding rod 43 moves the compression spring 44 along with the door 12; when the door 12 is opened, the lifting block 31 descends to release the free end of the rotating arm 32, the thrust at the other end of the rotating arm 32 is released, the compression spring 44 pushes the sliding rod 43, the sliding rod 43 drives the door 12 to move out of the doorframe, then the sliding block 22 is pulled to slide in the direction away from the doorframe, the connecting plate 23 is driven to pull the door 12 to slide in the direction away from the doorframe, and the door opening action is completed.
The whole structure of the car door structure is simple, and the production and maintenance cost can be effectively reduced. The lifting block 31 can protect the door 12, that is, when the door 12 is not slid in place, the rotating arm 32 will not slide to the top end of the lifting block 31, and at this time, even if the lifting block 31 is lifted, the door 12 will not be pushed, and the door 12 is prevented from being pushed to hit the compartment 11 without being in place.
As an embodiment of driving the pulling slider 22, as shown in fig. 3 and 5, the pulling mechanism 2 further includes a pulling guide rail 21, a pulling rack 24, and a pulling motor 25; the pulling guide rail 21 is fixedly connected with the top of the carriage 11, and the pulling guide rail 21 is parallel to the carriage 11; a plurality of pulling sliders 22 and connecting plates 23 are arranged, the connecting plates 23 are fixedly connected with the top end of the vehicle door 12 at equal intervals, each pulling slider 22 is fixedly connected with one corresponding connecting plate 23, and the pulling sliders 22 are fixedly connected with one pulling rack 24; the pulling motor 25 is fixedly connected with the carriage 11, and the output end of the pulling motor 25 is meshed with the pulling rack 24.
The pulling slide block 22 and the connecting plate 23 are provided with a plurality of pulling slide blocks, so that the stress of the vehicle door 12 is more uniform when the vehicle door is pulled, the fracture of the joint of the vehicle door 12 and the connecting plate 23 caused by the excessive pulling force generated by the single connecting plate 23 on the vehicle door 12 is avoided, and the reliability of the structure is improved. All the pulling sliders 22 and one pulling rack 24 are connected into a whole, so that the synchronization of the actions of the pulling sliders 22 is ensured, the change of the distance between the connecting plates 23 caused by the speed difference between the pulling sliders 22 is avoided, and the influence of the pulling of the plurality of connecting plates 23 on the vehicle door 12 on the safety of the vehicle door 12 is prevented.
Since the door 12 inevitably generates vibration and impact during movement, in order to reduce the influence of the vibration and impact on the door structure, as shown in fig. 2 to 3, the door further includes a first buffer plate 5, and the first buffer plate 5 is fixedly installed at the top end of the compartment 11; the first buffer plate 5 and the top of the carriage 11 form a cavity structure; the pull rail 21 is fixedly mounted on the first buffer plate 5. The cavity structure enables the first buffer plate 5 to generate slight deformation, thereby effectively buffering the vibration and impact generated by the vehicle door 12, and particularly preventing the danger caused by the fact that the fixing part for pulling the guide rail 21 is loosened and falls off under the influence of the vibration and the impact when the guide rail 21 is pulled.
Since the pulling mechanism 2 cannot be kept above the vehicle door 12 all the time, and a certain vertical rotation is generated when the vehicle door 12 is closed, the vehicle door 12 generates a certain moment on the pulling mechanism 2, and in order to balance the moment, as shown in fig. 2-3, the vehicle door further comprises a torsion-resistant guide rail 6, and the torsion-resistant guide rail 6 is fixedly installed on the first buffer plate 5; the two side walls of the torsion resistant rail 6 extend vertically downwards; the pulling mechanism 2 is provided with a torsion-resistant pulley 26, which torsion-resistant pulley 26 extends between the two side walls of the torsion-resistant rail 6 and rolls on the side walls of the torsion-resistant rail 6. The anti-torque guide wheel 26 will abut against the side wall of the anti-torque guide rail 6 under the action of torque, thereby acting against the force generated by the anti-torque guide wheel 26 and balancing the torque of the door 12 on the connecting plate 23. The torsion-resistant guide rail 6 is fixedly arranged on the first buffer plate 5, so that the first buffer plate 5 can play a role of buffering the torsion-resistant guide rail 6.
Since the torque effect of the vehicle door 12 is much larger than the vibration of the vehicle door 12, in order to prevent the torsion-resistant guide rail 6 from causing an excessive deformation of the first buffer plate 5 to affect the pull guide rail 21, as shown in fig. 10, the first buffer plate 5 is provided with a first horizontal section 51 and a second horizontal section 52, and the first horizontal section 51 and the second horizontal section 52 are connected by a vertical section 53; the pull rail 21 is fixedly mounted on the first horizontal section 51 and the torsion resistant rail 6 is fixedly mounted on the second horizontal section 52. The first horizontal segment 51 and the second horizontal segment 52 are separated by the vertical segment 53, and the vertical segment 53 can generate a certain angle deflection to adapt to the deformation caused by the torsion of the torsion-resistant guide rail 6 balancing the torsion of the vehicle door 12, so as to avoid the mutual influence between the torsion-resistant guide rail 6 and the pulling guide rail 21.
In order to improve the fixing reliability of the first buffer plate 5, as shown in fig. 10, fixing sections 54 bent outward are provided at both ends of the first buffer plate 5, and the fixing sections 54 are tightly attached to the inner wall of the car 11. The fixed section 54 increases the fixed area of the first buffer plate 5 to the car 11, so that the load of the car 11 is more even.
Also in order to reduce the impact of vibration and impact on the door structure, as shown in fig. 9, one end of the sliding rod 43 is provided with a second buffer plate 431, and the second buffer plate 431 is fixedly connected with the door 12 and forms a cavity structure with the door 12. The cavity structure allows the second damping plate 431 to be slightly deformed for absorbing shock and impact of the movement of the door 12.
Preferably, as shown in fig. 6 to 8, the support rail 41 includes a fixed rail 411 and a lifting rail 412; the fixed guide rail 411 is fixedly arranged on the carriage 11, and the lifting guide rail 412 is fixedly arranged on the lifting block 31; when the lifting block 31 is lifted, one end of the rotating arm 32 abuts against the side wall of the fixed rail 411. The lifting guide rail 412 and the top surface of the lifting block 31 form an L-shaped structure which can prop against the free end of the rotating arm 32 to prevent the sliding of the free end from causing the failure of the door pushing mechanism 3; meanwhile, when the elevator block 31 is raised, the elevator rail 412 is also raised to block the support mechanism 4, so that the support mechanism 4 cannot slide on the support rail 41, thereby preventing the vehicle door 12 from sliding in the longitudinal direction of the vehicle compartment 11 when closed.
As a way of realizing the up-and-down sliding of the lifting block 31, as shown in fig. 6 to 8, the door pushing mechanism 3 further includes a screw 33, a sliding nut 34, and a rotating rod 35; the screw rod 33 is rotatably connected with the carriage 11; the screw rod 33 is provided with a first thread section 331 and a second thread section 332, and the thread directions of the first thread section 331 and the second thread section 332 are opposite; the two sliding nuts 34 are respectively sleeved on the first thread section 331 and the second thread section 332 in a threaded connection manner; one end of each of the two rotation rods 35 is hinged to the two sliding nuts 34, and the other end is hinged to one of the lifting blocks 31. The screw 33 rotates to drive the two sliding nuts 34 to move close to or away from each other, and further drives the rotating rod 35 to rotate, so that the lifting block 31 ascends or descends. This structure enables the elevator block 31 to ascend and descend smoothly, and prevents the elevator block 31 from being impacted when ascending or descending.
To facilitate the rotation of the rotating arm 32, as shown in fig. 6 to 8, a roller 321 is provided at the free, drooping end of the rotating arm 32. Meanwhile, the roller 321 can effectively prevent the rotating arm 32 from scratching the carriage 11 and the lifting block 31.
The foregoing illustrates and describes the principles, general features, and advantages of the present invention. It will be understood by those skilled in the art that the present invention is not limited to the embodiments described above, which are described in the specification and illustrated only to illustrate the principle of the present invention, but that various changes and modifications may be made therein without departing from the spirit and scope of the present invention, which fall within the scope of the invention as claimed.
