[0047] In the related art, there is a certain limit requirement for the goods, or the two ends of the flat car that need to transport vehicles and other goods will be provided with end doors that are rotatably connected to the body of the flat car. The end door rotates relative to the body of the flat car to protrude vertically relative to the body, which plays a certain limit role. The end door rotates relative to the body of the flat car to be horizontally supported on the body. The horizontally placed end door can play a transitional role between different bodies of the flat car, for unloading of goods or for the passage of goods such as vehicles, etc. When the end door is in a state of vertically protruding relative to the body, it is necessary to use a latch or fastener to position the end door and the body. The position of the latch or fastener is usually located between the two bodies. There is a certain danger in manually operating the latch or fastener to connect the end door and the body, and the efficiency is not high, which will affect the state change efficiency of the end door, so that the transportation or loading and unloading of goods is affected, and the loading and unloading efficiency of the flat car is affected. There is a technical problem that the loading and unloading efficiency of the flat car is not ideal. The embodiment of the present application provides a flat car, which can at least solve the above technical problems to a certain extent.

[0048] The present application will be described below with reference to the accompanying drawings:

[0049] Figure 1A schematic diagram of the structure of a flat car in some embodiments or certain embodiments of the present application is shown. Figure 2 It shows a schematic diagram of the end structure of a flat car in some embodiments or certain embodiments of the present application, Figure 3 A front view of the end of a flat car in some embodiments or certain embodiments of the present application is shown, with reference to Figures 1 to 3 , an embodiment of the present application provides a flat car, comprising:

[0050] The vehicle body 1 is provided with two ends.

[0051] The two end doors 2 are opposite to each other and are rotatably connected to the two ends 11 of the vehicle body 1 respectively.

[0052] The positioning assembly 3 is provided with a transmission part 31 and a plug-in part 32. The transmission part 31 is rotationally connected to the end door 2 and extends to at least one side of the vehicle body 1. The plug-in part 32 is driven by the transmission part 31 and is connected to the transmission part 31. The transmission part 31 rotates relative to the end door 2 until the plug-in part 32 is inserted into the vehicle body 1.

[0053] The two end doors 2 are opposite to each other and are rotatably connected to the two ends of the vehicle body 1. The end doors 2 can be rotated relative to the vehicle body 1 to vertically protrude from the vehicle body 1, and play a limiting role on the goods on the vehicle body 1. The end doors 2 can also be rotated relative to the vehicle body 1 to be horizontally supported on the vehicle body 1 for the passage of vehicles and other goods. The flat car is also provided with a positioning assembly 3, and the positioning assembly 3 is provided with a transmission part 31 and a plug-in part 32. The transmission part 31 of the positioning assembly 3 is rotatably connected to the end door 2, and the transmission part 31 extends to at least one side of the vehicle body 1. When the end door 2 is rotated to a state where positioning is required, such as protruding relative to the vehicle body 1, the operator can operate the transmission part 31 from one side or both sides of the vehicle body 1 to rotate the transmission part 31 relative to the end door 2, and the plug-in part 32 is driven by the transmission part 31 to be connected to the transmission part 31, and the plug-in part 32 can be driven by the transmission part 31 to be inserted into the vehicle body 1. There is a certain space on both sides of the body 1 of the flat car, and the transmission part 31 extending to at least one side of the body 1 can have a safer operating space, which improves the safety of the operator operating the transmission part 31. After the plug-in part 32 is plugged into the body 1, the plug-in part 32 is limited by the body 1. The plug-in part 32 and the transmission part 31 are in the same positioning assembly 3, and there is a force transmission between the plug-in part 32 and the transmission part 31. When the plug-in part 32 is limited by the body 1, the transmission part 31 is also limited to a certain extent. The limited transmission part 31 can play a certain role in limiting and supporting the end door 2, so that the position of the end door 2 relative to the body 1 can be fixed to a certain extent. The plug-in part 32 can move to be inserted into the vehicle body 1 with the rotation of the transmission part 31, and the plug-in part 32 can also move to be separated from the vehicle body 1 with the rotation of the transmission part 31. When the end door 2 needs to be rotated relative to the vehicle body 1, the operator can also manually operate the transmission part 31 at one side of the vehicle body 1 to separate the plug-in part 32 from the vehicle body 1. The staff operates the transmission part 31 beside the flat car to complete the positioning or relaxation of the end door 2, and then changes the state of the end door 2. The operation is simple and safe, and the time for changing the state of the end door 2 can be increased to facilitate the movement and loading and unloading of goods, improve the loading and unloading efficiency of the flat car for goods, and to a certain extent solve the technical problem that the loading and unloading efficiency of the flat car is not ideal.

[0054] It should be noted that the positioning assembly 3 is connected to one end door 2 of the vehicle body 1, which can correspondingly reduce the time required for positioning and adjusting the state of this end door 2, and to a certain extent can facilitate the movement and loading and unloading of goods by the flat car, and improve the efficiency of moving goods. When the plug-in portion 32 and the vehicle body 1 are in a separated state, the end door 2 can rotate freely relative to the vehicle body 1, and the rotation of the end door 2 relative to the vehicle body 1 can be driven manually or by a driving mechanism. In this application, the two ends of the vehicle body 1 are the two ends in the length direction of the vehicle body 1, and at least one side of the vehicle body 1 is at least one side in the width direction of the vehicle body 1.

[0055] In some or certain embodiments, the transmission part 31 is provided with two ends respectively extending to both sides of the vehicle body 1 , and both ends of the transmission part 31 are spaced apart from the end door 2 .

[0056] The transmission part 31 is provided with two ends extending to both sides of the vehicle body 1, and both ends are spaced apart from the end door 2, providing operating space for the operator. The operator can operate the transmission part 31 at any side of the flat car, effectively reducing the time to complete the positioning of the end door 2, reducing the time required for the state change of the end door 2, and helping to improve the loading and unloading efficiency of the flat car for goods.

[0057] In some or certain embodiments, the positioning component 3 includes:

[0058] The handle 33 is connected to a peripheral wall of one end of the transmission part 31 .

[0059] The positioning assembly 3 also includes a handle 33 connected to the peripheral wall of one end of the transmission part 31. The operator can operate the transmission part 31 through the handle 33 to facilitate the control of the rotation of the transmission part 31 and quickly complete the positioning or release of the end door 2 to improve the loading and unloading efficiency of the flat car for goods.

[0060] In some or certain embodiments, the positioning assembly 3 may include two handles 33, and the two wrenches are respectively connected to the two ends of the transmission part 31. This facilitates operation and improves the loading and unloading efficiency of the flat car for goods.

[0061] In some or certain embodiments, the flat car may also include two positioning assemblies 3, and the transmission parts 31 of the two positioning assemblies 3 are respectively rotatably connected to the two end doors 2. The states of the two end doors 2 can be controlled, and when loading goods such as vehicles, the two end doors 2 can be laid flat for vehicles to pass through.

[0062] In some or certain embodiments, the two end doors 2 may be located between the two positioning components 3, and the plug-in parts 32 of the two positioning components 3 may be respectively used to connect with the two ends of the vehicle body 1. This can effectively reduce the possibility of interference. The positioning component 3 may also be arranged on one side of the vehicle body 1, and the plug-in part 32 may also be inserted into one side of the vehicle body 1. This can also achieve connection and fixation.

[0063] In some or certain embodiments, the positioning component 3 may include:

[0064] The rotating structural member is configured as a transmission part 31 .

[0065] The plug-in connector is connected to the peripheral wall of the rotary structure, and the side away from the rotary structure is configured as a plug-in portion 32.

[0066] The rotating structural member is configured as a transmission part 31. The structure of the rotating structural member facilitates the rotational coordination with the end door 2. The connector is connected to the peripheral wall of the rotating structural member. The side of the connector away from the rotating structural member is configured as a plug-in part 32, which can enable a certain distance to exist between the plug-in part 32 and the rotating structural member. When the rotating structural member rotates relative to the end door 2, the plug-in part 32 can have a larger linear speed, which facilitates the plug-in part 32 to move quickly to connect with the vehicle body 1.

[0067] It should be noted that the rotary structural member is configured as the transmission part 31 , and the two axial ends of the rotary structural member can be configured as the two ends of the transmission part 31 respectively.

[0068] In some or certain embodiments, one end of the rotary structure can be rotated and inserted into the end door 2, and the other end of the rotary structure can extend out of the end door 2 and to one side of the vehicle body 1. This can also facilitate the operation of the operator.

[0069] In some or certain embodiments, the end door 2 may be provided with a protrusion 24 for the rotary structure to pass through, the rotary structure can pass through the protrusion 24 and can rotate around its own axis, and the two ends of the rotary structure extend to the two sides of the vehicle body 1 respectively. This facilitates the assembly of the rotary structure and the end door 2, and also facilitates the operation of the two ends of the rotary structure to control the position of the plug-in portion 32.

[0070] In some or certain embodiments, the positioning assembly 3 may include at least two connectors, and the at least two connectors are spaced apart and distributed along the axial direction of the rotating structure.

[0071] At least two connectors are distributed along the axial direction of the rotating structure, and each connector is connected to the peripheral wall of the rotating structure. The connector is provided with a plug-in portion 32. Then, at least two connectors can move to be inserted into the vehicle body 1 as the rotating structure rotates, thereby enhancing the supporting and positioning effect of the end door 2.

[0072] In some or certain embodiments, the plug-in component may be plate-shaped, block-shaped, or rod-shaped, and the vehicle body 1 may be provided with a hole or slot corresponding to the plug-in portion 32 of the plug-in component. When the rotary structure rotates a certain angle relative to the end door 2, the plug-in component moves with the rotary structure, and the plug-in portion 32 of the plug-in component can rotate to insert into the corresponding hole or slot on the vehicle body 1, thereby completing the positioning of the plug-in portion 32 and the rotary structure.

[0073] In some or certain embodiments, the vehicle body 1 is provided with a positioning groove 12 and a limiting member 4 inserted into the positioning groove 12, the plug-in portion 32 is provided with a waist-shaped hole 322 movably sleeved on the limiting member 4, and the plug-in portion 32 is used to move to be inserted into the positioning groove 12 or separate from the positioning groove 12 as the transmission portion 31 rotates.

[0074] The positioning groove 12 provided on the vehicle body 1 is for the plug-in part 32 to be inserted and matched, and a limiting piece 4 is provided in the positioning groove 12, and the plug-in part 32 can be movably mounted on the limiting piece 4. When the transmission part 31 rotates relative to the end door 2, the transmission part 31 can drive the plug-in part 32 to move, and the plug-in part 32 can be inserted into the positioning groove 12 or separated from the positioning groove 12 during movement. However, the plug-in part 32 can also be movably mounted on the limiting piece 4 in the positioning groove 12 at the same time. Even if the plug-in part 32 is separated from the positioning groove 12, the limiting piece 4 can also play a certain limiting role on the plug-in part 32 to prevent the plug-in part 32 from falling. Subsequently, adjusting the position of the transmission part 31 can also drive the plug-in part 32 to move and insert into the positioning groove 12.

[0075] It should be noted that when the plug-in portion 32 is inserted into the positioning groove 12, there is abutment or other interaction between the plug-in portion 32 and the bottom or wall of the positioning groove 12; the plug-in portion 32 is separated from the positioning groove 12, which means that there is no contact relationship between the plug-in portion 32 and the bottom of the positioning groove 12.

[0076] For ease of understanding, here is provided Figure 4 and Figure 5 , Figure 4 A schematic diagram of a use state of a positioning component in some embodiments or certain embodiments of the present application is shown, Figure 5 A schematic diagram showing another use state of the positioning component in some embodiments or certain embodiments of the present application is shown. Figure 4 The middle plug-in portion 32 is inserted into the positioning groove 12 of the vehicle body 1, and the end door 2 is in a vertical state. Figure 5 The middle plug-in portion 32 is separated from the positioning groove 12 of the vehicle body 1, and the end door 2 is in a horizontal position.

[0077] In some or certain embodiments, the stopper 4 may be a pin or a column, etc. The stopper 4 may be connected to the vehicle body 1 and inserted into the positioning groove 12 or located in the positioning groove 12. A hole corresponding to the stopper 4 may be provided on the plug-in portion 32, and the hole corresponding to the stopper 4 has a larger diameter than the stopper 4, so that the stopper 4 can limit the plug-in portion 32.

[0078] In some or certain embodiments, the vehicle body 1 is provided with a protruding matching portion 13 , the positioning groove 12 is provided on the matching portion 13 , and the limiting member 4 is detachably connected to the matching portion 13 .

[0079] The vehicle body 1 has a protruding mating portion 13 , and the mating portion 13 has a positioning groove 12 , which is convenient for mating with the plug-in portion 32 . The limiting member 4 is detachably connected to the mating portion 13 , which is convenient for disassembly, assembly and maintenance of the positioning assembly 3 .

[0080] In some or certain embodiments, both ends of the vehicle body 1 may be provided with a matching portion 13, and the matching portion 13 at each end of the vehicle body 1 may be matched with a corresponding plug-in portion 32, thereby improving the overall positioning and supporting effect.

[0081] Figure 6 FIG. 1 shows a schematic diagram of a positioning assembly in some embodiments or certain embodiments of the present application, with reference to FIG. Figure 6 In some or certain embodiments, the vehicle body 1 is provided with a positioning groove 12 and a stopper 4 inserted into the positioning groove 12, and the positioning assembly 3 includes:

[0082] The rotating structural member is configured as a transmission part 31 .

[0083] The transition piece 34 is connected to the peripheral wall of the rotary structure. The plug-in portion 32 can be movably sleeved on the transition piece 34 and the limiting member 4. The plug-in portion 32 is used to move to the insertion positioning groove 12 or separate from the positioning groove 12 as the rotary structure rotates.

[0084] The positioning groove 12 of the vehicle body 1 can be used for the insertion and positioning of the plug-in part 32. The rotating structural member in the positioning assembly 3 is used to achieve the cooperation with the end door 2. The setting of the transition piece 34 facilitates the connection and movement of the plug-in part 32. The plug-in part 32 can be movably sleeved on the transition piece 34 and the limiter 4. When the rotating structural member rotates, there can be a certain adjustment space between the transition piece 34 and the plug-in part 32. After the transition piece 34 rotates to a certain extent, it can abut against the plug-in part 32. The transition piece 34 continues to rotate with the transmission part 31 to drive the plug-in part 32 to move to separate from the positioning groove 12. At the same time, the plug-in part 32 can be limited by the limiter 4, and the plug-in part 32 will not fall. When the plug-in part 32 needs to be reinserted into the positioning groove 12, the transmission part 31 is rotated in the reverse direction so that the plug-in part 32 can be driven to be reinserted into the positioning groove 12.

[0085] It should be noted that when the limit member 4 is inserted into the positioning groove 12 and the plug-in portion 32 can be movably mounted on the limit member 4, the positioning groove 12 can be set as a U-shaped groove or a special-shaped groove with a groove opening inclined relative to the end 11 of the vehicle body 1, and accordingly the limit member 4 can be set at the opening or edge of the positioning groove 12, so that the plug-in portion 32 can be movably mounted on the limit member 4, and the plug-in portion 32 can be separated from the positioning groove 12 while being mounted on the limit member 4.

[0086] In some or certain embodiments, the plug-in portion 32 is provided with a movable hole 321 and a waist-shaped hole 322 which are spaced apart from each other and whose axes extend along the axial direction of the rotating structure. The movable hole 321 is movably sleeved on the transition piece 34 , and the waist-shaped hole 322 is movably sleeved on the limiting piece 4 .
