[0034] The preferred embodiments of the present invention will be described in more detail below. Although the preferred embodiments of the present invention are described below, it should be understood that the present invention can be implemented in various forms and should not be limited by the embodiments set forth herein. On the contrary, these embodiments are provided to make the present invention more thorough and complete, and to fully convey the scope of the present invention to those skilled in the art.

[0035] The present invention provides an electrically controlled flip-up side door for a rail logistics vehicle, comprising:

[0036] The side door mechanism comprises two side doors symmetrically arranged on both sides of the carriage, and the tops of the side doors are hinged to the carriage;

[0037] Two opening and closing mechanisms are arranged between the two side doors. The opening and closing mechanisms include an electric hydraulic push rod, which is drive-connected to the side door. When the output end of the electric hydraulic push rod is extended, the side door is switched to an open state.

[0038] Specifically, the upward-flipping side door includes a side door mechanism and an opening and closing mechanism. The two symmetrically arranged side doors can be upward-flipped and opened through the opening and closing mechanism. In addition, an electric hydraulic push rod is arranged in the opening and closing mechanism to reduce the use of manpower and reduce labor intensity.

[0039] Optionally, the opening and closing mechanism includes:

[0040] A first connecting rod, one end of which is hinged to the roof of the carriage;

[0041] A second connecting rod, one end of which is hinged to the other end of the first connecting rod, and the other end of the second connecting rod is hinged to the side door;

[0042] The electric hydraulic push rod is arranged below the first connecting rod and the second connecting rod, and one end of the electric hydraulic push rod is hinged to the middle part of the first connecting rod.

[0043] Specifically, two connecting rods are arranged in the opening and closing mechanism, and the connecting rods and the connecting rods and the electric hydraulic push rod are hingedly connected. This can reduce the space occupied by the opening and closing mechanism. When the output end of the electric hydraulic push rod is extended, the first connecting rod can be pushed to both sides of the car body, thereby driving the second connecting rod to lift the side door, so that the car door can be opened.

[0044] Optionally, the first connecting rod is connected to the ceiling of the carriage through a connecting rod support, and the connecting rod support includes:

[0045] A support plate, with bearing blocks respectively arranged at both ends of the support plate;

[0046] The rotating shaft is connected with the bearing parts of the two bearing blocks. One end of the first connecting rod is provided with a mounting hole, and the mounting hole and the rotating shaft are connected with a flat key.

[0047] Specifically, the first connecting rod is connected to the ceiling of the carriage, and the first connecting rod and the ceiling are hingedly connected, so that a connecting rod support is used for transmission between the first connecting rod and the ceiling, the connecting rod support is fixed to the ceiling through a support plate, and two bearing blocks are arranged on the support plate, and a rotating shaft is arranged between the two bearing blocks, so that the rotating shaft can rotate clockwise and counterclockwise under the drive of the bearings, and finally the first connecting rod is sleeved on the rotating shaft and fixedly connected by a flat key, so that the first connecting rod can drive the rotating shaft to rotate freely, and when the output end of the electric hydraulic push rod telescopes, the first connecting rod can realize synchronous rotation.

[0048] Optionally, the connecting rod support also includes an angle sensor, which is arranged on the outside of a bearing block through a fixing plate, one end of the rotating shaft passes through the bearing block and extends toward the angle sensor, and the sensing end of the angle sensor cooperates with one end of the rotating shaft.

[0049] Specifically, an angle sensor is also provided on the outside of a bearing block, and the rotating shaft extends to the outside of the bearing block and is provided corresponding to the angle sensor, so that the angle of rotation of the rotating shaft driven by the first connecting rod can be monitored by the angle sensor, and then the opening or closing angle of the side door driven by the second connecting rod can be known by conversion. Since the two ends of the side door are driven by an electric hydraulic push rod respectively, the electric hydraulic push rod can drive the second connecting rod to push the side door after driving the first connecting rod to rotate, so that the rotation angles of the first connecting rod and the second connecting rod are monitored by the angle sensors at both ends of the side door, so that the opening angles at both ends of the side door can be kept consistent, ensuring the force balance of the side door.

[0050] Optionally, the electric hydraulic push rod is arranged corresponding to the end of the side door, and the electric hydraulic push rods corresponding to the two symmetrically arranged side doors are cross-arranged.

[0051] Specifically, multiple side doors can be set on both sides of a carriage, and the side doors on both sides need to be set symmetrically. Two opening and closing mechanisms are set between the same ends of the two side doors. The two opening and closing mechanisms respectively drive the second connecting rod through the electric hydraulic push rod to flip the side door upward to the outside of the carriage and open it. Since the movement directions of the electric hydraulic push rod and the second connecting rod in the two opening and closing mechanisms are opposite, the electric hydraulic push rods in the two opening and closing mechanisms can be cross-arranged. In addition to not affecting the function of synchronously opening the side doors on both sides, the space occupied by the opening and closing mechanisms in the carriage can also be reduced.

[0052] Optionally, the electric hydraulic push rod is connected to the bottom plate of the carriage via a push rod support.

[0053] Optionally, the side door mechanism comprises:

[0054] A hinge, one end of which is connected to the side door, and the other end of which is connected to the top of the carriage;

[0055] The lock seat is arranged at the bottom of the side door, and the side door is connected with the other end of the second connecting rod through the connecting seat.

[0056] Optionally, the side door is made of aluminum alloy profile and has a frame structure.

[0057] Specifically, since the flip-up side door is driven by an electric hydraulic push rod, the size of the side door can be increased, which can meet the requirements of loading and taking out multiple push trays. The side door is set as a frame structure, which can increase the load-bearing strength of the side door. The frame structure is composed of aluminum alloy profiles and plates, which can reduce the dead weight of the side door. A lock seat is also set at the bottom of the side door, which can serve as a side wall of the carriage when the side door is closed to protect the goods carried in the carriage.

[0058] The present invention also provides a rail vehicle, comprising the above-mentioned electrically controlled flip-up side door for rail logistics vehicles.

[0059] Example

[0060] like Figures 1 to 5 As shown, the present invention provides an electrically controlled flip-up side door for a rail logistics vehicle, comprising:

[0061] The side door mechanism 1 comprises two side doors 2 symmetrically arranged on both sides of the carriage, and the tops of the side doors 2 are hinged to the carriage 3;

[0062] Two opening and closing mechanisms 4 are arranged between the two side doors 2. The opening and closing mechanisms 4 include an electric hydraulic push rod 5. The electric hydraulic push rod 5 is drivingly connected to the side door 2. When the output end of the electric hydraulic push rod 5 is extended, the side door 2 is switched to an open state.

[0063] In this embodiment, the opening and closing mechanism 4 includes:

[0064] A first connecting rod 6, one end of which is hinged to the ceiling of the carriage 3;

[0065] A second connecting rod 7, one end of which is hinged to the other end of the first connecting rod 6, and the other end of the second connecting rod 7 is hinged to the side door 2;

[0066] The electric hydraulic push rod 5 is arranged below the first connecting rod 6 and the second connecting rod 7 , and one end of the electric hydraulic push rod 5 is hinged to the middle part of the first connecting rod 6 .

[0067] In this embodiment, the first connecting rod 6 is connected to the ceiling of the carriage 3 through a connecting rod support 8, and the connecting rod support 8 includes:

[0068] A support plate 9, with bearing blocks 10 disposed at both ends of the support plate 9;

[0069] The rotating shaft 11 is connected to the bearing parts of the two bearing blocks 10 . A mounting hole is provided at one end of the first connecting rod 6 . The mounting hole and the rotating shaft 11 are connected by a flat key 12 .

[0070] In this embodiment, the connecting rod support 8 also includes an angle sensor 13, which is arranged on the outside of a bearing block 10 through a fixing plate 14. One end of the rotating shaft 11 passes through the bearing block 10 and extends toward the angle sensor 13. The sensing end of the angle sensor 13 cooperates with one end of the rotating shaft 11.

[0071] In this embodiment, the electric hydraulic push rods 5 are arranged corresponding to the ends of the side doors 2, and the electric hydraulic push rods 5 corresponding to the two symmetrically arranged side doors 2 are arranged crosswise.

[0072] In this embodiment, the electric hydraulic push rod 5 is connected to the bottom plate of the carriage 3 via a push rod support 18 .

[0073] In this embodiment, the side door mechanism 1 includes:

[0074] A hinge 15, one end of which is connected to the side door 2, and the other end of which is connected to the top of the carriage 3;

[0075] The lock seat 16 is arranged at the bottom of the side door 2 , and the side door 2 is connected to the other end of the second connecting rod 7 via the connecting seat 17 .

[0076] In this embodiment, the side door 2 is made of aluminum alloy profile and is a frame structure.

[0077] The present invention also provides a rail vehicle, comprising the above-mentioned electrically controlled flip-up side door for rail logistics vehicles.

[0078] In summary, the flip-up side door is mainly composed of a side door mechanism 1 and an opening and closing mechanism 4, wherein the side door 2 is arranged in a two-layer symmetrical manner. When the output end of the electric hydraulic push rod 5 is extended, the side doors on both sides of the carriage 3 can be flipped up. The two opening and closing mechanisms 4 are staggered between the two symmetrically arranged side doors. Each opening and closing mechanism 4 is independently controlled by the side door 2 on one side. In the opening and closing mechanism 4, the electric hydraulic push rod 5 drives the first connecting rod 6 to rotate, and the first connecting rod 6 then drives the second connecting rod 7 to rotate, so that the second connecting rod 7 can drive the side door to realize the opening and closing action. A lock seat 16 is also arranged at the bottom of the side door. When the side door 2 is closed on the carriage 3, the electromagnetic push rod can be used to lock the side door through the lock seat 16. In the opening and closing structure 4, the upper end of the first connecting rod 6 is hinged to the top of the car body 3 through the connecting rod support 8, and the lower end of the first connecting rod 6 is hinged to the lower end of the second connecting rod 7. The upper end of the second connecting rod 7 is hinged to the inner side of the side door 2. When the electric hydraulic push rod 5 pushes the first connecting rod 6 to rotate, the second connecting rod 7 can drive the side door 2 to open and close. At the same time, the first connecting rod 6 drives the rotating shaft 11 to rotate. The rotation angle of the first connecting rod 6 can be understood through the angle sensor 13, so that the opening and closing angle of the side door can be pushed out, so that the opening and closing control of the side door can be more accurate, ensuring the balance of the driving force at both ends of the side door.

[0079] The embodiments of the present invention have been described above, and the above description is exemplary, not exhaustive, and is not limited to the disclosed embodiments. Many modifications and changes will be apparent to those skilled in the art without departing from the scope and spirit of the described embodiments.
