[0062] In the related art, the hopper car has a technical problem that the touch-type bottom door opening and closing mechanism is inconvenient to use. The embodiment of the present application provides a hopper box bottom door unit and a hopper box, which can at least solve the technical problem that the hopper car adopts a touch-type bottom door opening and closing mechanism, which is inconvenient to use.

[0063] The present application is described below with reference to the accompanying drawings and specific embodiments:

[0064] like Figures 1 to 8 As shown, the hopper box bottom door unit 100 is installed on the box body 200 of the hopper box 1000, and the box body 200 of the hopper box 1000 is provided with a material leakage port. The hopper box bottom door unit 100 includes a bottom door mechanism 110, a door closing drive assembly 120, and a door opening drive assembly 130. The bottom door mechanism 110 is installed on the box body 200, and has a shielding position for shielding the material leakage port and an opening position for opening the material leakage port; the door closing drive assembly 120 is installed on the box body 200 and connected to the bottom door mechanism 110, and is used to drive the bottom door mechanism 110 to move so that the bottom door mechanism 110 is located in the shielding position; the door opening drive assembly 130 is installed on the box body 200 and connected to the bottom door mechanism 110, and is used to drive the bottom door mechanism 110 to move so that the bottom door mechanism 110 is located in the opening position.

[0065] The bottom of the box body 200 of the hopper box 1000 is provided with a material leakage port, and the material in the hopper box 1000 leaks out through the material leakage port. The bottom door mechanism 110 is installed on the box body 200, and the bottom door mechanism 110 can cover the material leakage port, so that the material leakage port is in a closed state, and the material in the hopper box 1000 cannot leak out through the material leakage port. The bottom door mechanism 110 can also not cover the material leakage port, so that the material leakage port is in an open state, and the material in the hopper box 1000 can leak out through the material leakage port.

[0066] The door closing drive assembly 120 is mounted on the housing 200, and is connected to the bottom door mechanism 110, and is used to drive the bottom door mechanism 110 to move, so that the bottom door mechanism 110 can be located in the shielding position. The door opening drive assembly 130 is mounted on the housing 200, and is connected to the bottom door mechanism 110, and is used to drive the bottom door mechanism 110 to move, so that the bottom door mechanism 110 can be located in the opening position.

[0067] After such design, the funnel box bottom door unit 100 has a door closing drive component 120 for controlling the closing of the bottom door mechanism 110 and a door opening drive component 130 for controlling the opening of the bottom door mechanism 110. The funnel box 1000 having the funnel box bottom door unit 100 of the present application can realize the opening and closing of the bottom door mechanism 110 by its own structure, and there is no need to realize the opening and closing of the bottom door mechanism 110 by cooperating with ground facilities. The opening and closing of the bottom door mechanism 110 is more convenient, which helps to improve the opening efficiency and closing efficiency of the bottom door mechanism 110, thereby improving the transportation efficiency of the funnel box 1000. The opening and closing of the bottom door mechanism 110 are respectively realized by the door opening drive component 130 and the door closing drive component 120 rather than by a group of drive components. This design can more accurately control the movement speed of the bottom door mechanism 110, ensure the stability and reliability of the opening and closing actions, and facilitate the maintenance and optimization of the door opening drive component 130 and the door closing drive component 120 respectively. Once a problem occurs, it can be quickly located and solved, thereby ensuring the efficient operation and safety performance of the funnel box bottom door unit 100 and improving the opening and closing efficiency and safety of the bottom door mechanism 110.

[0068] The specific structure of the bottom door mechanism 110 is diverse and well known to those skilled in the art, and is not limited in this application.

[0069] In some embodiments, Figure 1 and Figure 2 As shown, the bottom door mechanism 110 includes a main shaft assembly 111, a door panel assembly 112 and a connecting rod assembly 113. The main shaft assembly 111 is rotatably connected to the housing 200, and the door closing drive assembly 120 and the door opening transmission mechanism 132 are both connected to the main shaft assembly 111; the door panel assembly 112 is rotatably connected to the housing 200, and the door panel assembly 112 is used to cover the material leakage port; the connecting rod assembly 113 is hinged to the main shaft assembly 111 and the door panel assembly 112.

[0070] The upper end of the door panel assembly 112 is rotatably connected to the box body 200, and the connecting rod assembly 113 is located between the door panel assembly 112 and the main shaft assembly 111. One end of the connecting rod assembly 113 is rotatably connected to the middle of the door panel assembly 112, and the other end is rotatably connected to the main shaft assembly 111. The door closing drive assembly 120 and the door opening drive assembly 130 are both connected to the main shaft assembly 111, and are respectively used to drive the main shaft assembly 111 to move in two opposite directions. If the door closing drive assembly 120 drives the main shaft assembly 111 to rotate clockwise, the door opening drive assembly 130 drives the main shaft assembly 111 to rotate counterclockwise; if the door closing drive assembly 120 drives the main shaft assembly 111 to rotate counterclockwise, the door opening drive assembly 130 drives the main shaft assembly 111 to rotate clockwise. The main shaft assembly 111 rotates, driving the connecting rod assembly 113 to rotate, driving the door panel assembly 112 to rotate around the box body 200, so that the door panel assembly 112 opens or closes the leakage port. In some embodiments, the door closing drive assembly 120 drives the main shaft assembly 111 to rotate counterclockwise, and the door opening drive assembly 130 drives the main shaft assembly 111 to rotate clockwise. When the main shaft assembly 111 rotates clockwise, the door panel assembly 112 opens the material leakage port, and when the main shaft assembly 111 rotates counterclockwise, the door panel assembly 112 closes the material leakage port. In order to facilitate the introduction of the present application, the present application is introduced below by taking the example that when the main shaft assembly 111 rotates clockwise, the door panel assembly 112 opens the material leakage port, and when the main shaft assembly 111 rotates counterclockwise, the door panel assembly 112 closes the material leakage port.

[0071] In some embodiments, the door closing drive assembly 120 and the door opening transmission mechanism 132 are respectively disposed at two ends of the main shaft assembly 111 .

[0072] Specifically, along the axis of the main shaft assembly 111, the door closing drive assembly 120 is arranged at one end of the main shaft assembly 111, and the door opening drive assembly 130 is arranged at the other end of the main shaft assembly 111. The door closing drive assembly 120 and the door opening transmission mechanism 132 are respectively arranged at both ends of the main shaft assembly 111, which helps to keep the door closing drive assembly 120 and the door opening transmission mechanism 132 away from each other and avoid interference between the door closing drive assembly 120 and the door opening transmission mechanism 132.

[0073] In some embodiments, the door panel assembly 112 includes a first door panel 1121 and a second door panel 1122 that are relatively arranged, and the upper ends of the first door panel 1121 and the second door panel 1122 are both rotatably connected to the box body 200. The main shaft assembly 111 and the connecting rod assembly 113 are located between the two door panels, and the main shaft assembly 111 includes a main shaft 1111 and a first rotating arm 1112 and a second rotating arm 1113 that are fixedly arranged on the main shaft 1111, the first rotating arm 1112 is arranged on a side of the main shaft 1111 close to the first door panel 1121, and the second rotating arm 1113 is arranged on a side of the main shaft 1111 close to the second door panel 1122. The connecting rod assembly 113 includes a first connecting rod 1131 and a second connecting rod 1132. The first connecting rod 1131 is arranged between the first door panel 1121 and the first rotating arm 1112. One end of the first connecting rod 1131 is rotatably connected to one end of the first rotating arm 1112 away from the first main shaft 1111, and the other end is rotatably connected to the middle area of ​​the first door panel 1121. The second connecting rod 1132 is arranged between the second door panel 1122 and the second rotating arm 1113. One end of the second connecting rod 1132 is rotatably connected to one end of the second rotating arm 1113 away from the first main shaft 1111, and the other end is rotatably connected to the middle area of ​​the second door panel 1122. The rotation of the main shaft 1111 can drive the first rotating arm 1112 and the second rotating arm 1113 to rotate, thereby driving the first connecting rod 1131 and the second connecting rod 1132 to rotate, thereby making the lower ends of the first door panel 1121 and the second door panel 1122 approach each other or move away from each other. When the lower ends of the first door panel 1121 and the second door panel 1122 are close to each other, the first door panel 1121 and the second door panel 1122 respectively open the corresponding material leakage openings; when the lower ends of the first door panel 1121 and the second door panel 1122 are far away from each other, the first door panel 1121 and the second door panel 1122 respectively close the corresponding material leakage openings. In some embodiments, when the main shaft 1111 rotates clockwise, the lower ends of the first door panel 1121 and the second door panel 1122 are close to each other, and when the main shaft 1111 rotates counterclockwise, the lower ends of the first door panel 1121 and the second door panel 1122 are far away from each other.

[0074] In some embodiments, the main shaft assembly 111 includes two first rotating arms 1112 and two second rotating arms 1113, and the two first rotating arms 1112 and the two second rotating arms 1113 are spaced apart along the axis of the main shaft 1111. The connecting rod assembly 113 includes two first connecting rods 1131 and two second connecting rods 1132, and the two first connecting rods 1131 and the two second connecting rods 1132 are spaced apart in a direction parallel to the main shaft 1111.

[0075] like Figure 3As shown, in some embodiments, the door opening drive component 130 includes a door opening drive element 131 and a door opening transmission mechanism 132, and the door opening drive element 131 is installed on the box body 200; the door opening transmission mechanism 132 is installed on the box body 200 and is connected to the bottom door mechanism 110, and the door opening transmission mechanism 132 acts on the door opening drive element 131 and the bottom door mechanism 110; the door opening drive element 131 drives the door opening transmission mechanism 132 to move, so that the door opening transmission mechanism 132 drives the bottom door mechanism 110 to be in the open position.

[0076] The door opening drive element 131 and the door opening transmission mechanism 132 are both installed on the box body 200. The door opening transmission mechanism 132 is driven by the door opening drive element 131. The door opening drive element 131 drives the door opening transmission mechanism 132 to move, driving the main shaft component 111 of the bottom door mechanism 110 to rotate clockwise, thereby driving the door panel component 112 to rotate around the box body 200, so that the door panel component 112 opens the leakage port of the box body 200.

[0077] In some embodiments, the door opening transmission mechanism 132 includes a lever assembly 1323, a first transmission member 1321 and a contact member 1322, the middle portion of the lever assembly 1323 is hinged to the box body 200; the contact member 1322 is fixedly connected to the bottom door mechanism 110, one end of the lever assembly 1323 is located above the contact member 1322, the first transmission member 1321 is connected to the other end of the lever assembly 1323, and the door opening drive element 131 drives the first transmission member 1321 to move in the height direction, so that the lever assembly 1323 drives the contact member 1322 to move, so that the bottom door mechanism 110 is located in the open position.

[0078] The door opening drive element 131 drives the first transmission member 1321 to move in the height direction, and can drive the first transmission member 1321 to move upward or downward in the height direction. The contact member 1322 is fixedly connected to the main shaft 1111 of the main shaft assembly 111, and the middle part of the lever assembly 1323 is hinged on the box body 200. Therefore, if the end of the lever assembly 1323 connected to the first transmission member 1321 is raised, the end located above the contact member 1322 will be lowered. In this way, the lever assembly 1323 can press the contact member 1322 and press the contact member 1322 downward, so that the main shaft assembly 111 rotates clockwise by a certain angle, so that the main shaft assembly 111 passes the dead point. After the main shaft assembly 111 passes the dead point, the material in the box body 200 will push the door panel assembly 112 to continue to rotate, so that the door panel assembly 112 is fully opened. That is to say, after the lever assembly 1323 presses the contact member 1322 downward, so that the main shaft assembly 111 rotates clockwise and the door panel assembly 112 opens to a certain angle, the door panel assembly 112 will be fully opened under the gravity of the material. If the end of the lever assembly 1323 connected to the first transmission member 1321 is lowered, the end located above the contact member 1322 will rise. It is easy to understand that the contact member 1322 will return to the state when it is not pressed under the drive of the door closing drive assembly 120. Specifically, when the material is completely lowered, the door closing drive assembly 120 drives the main shaft assembly 111 to rotate counterclockwise, thereby causing the contact member 1322 to rotate counterclockwise, so that the contact member 1322 returns to the position when it is not pressed. The lever assembly 1323 and the first transmission member 1321 may be returned to the state where the contact member 1322 is not pressed under the action of the door opening drive element 131, or may be returned to the state where the contact member 1322 is not pressed under the action of the contact member 1322. If the lever assembly 1323 and the first transmission member 1321 are reset by the door opening drive element 131, the door opening drive element 131 drives the first transmission member 1321 to descend to the position before the elevation, thereby resetting the lever assembly 1323 and the first transmission member 1321. If the lever assembly 1323 and the first transmission member 1321 are reset by the contact member 1322, after the contact member 1322 rotates counterclockwise to a moving angle under the drive of the door closing drive assembly 120, the contact member 1322 will contact the lever assembly 1323, driving the end of the lever assembly 1323 located above the contact member 1322 to move upward, thereby resetting the lever assembly 1323 and the first transmission member 1321.

[0079] With this design, the lever assembly 1323 presses the contact piece 1322 downward, so that after the contact piece 1322 drives the main shaft assembly 111 to pass the dead point, the bottom door mechanism 110 can be fully opened under the action of the gravity of the material, and the contact piece 1322 and the lever assembly 1323 are separated, thereby overcoming the impact of the instantaneous rotational torque of the door panel assembly 112 passing the dead point on the door opening drive element 131, the lever assembly 1323 and the first transmission member 1321, which helps to extend the service life of the door opening drive element 131, the lever assembly 1323 and the first transmission member 1321, and ensure the continuous and stable operation of the door opening transmission mechanism 132. After such a design, under the action of the lever assembly 1323, the door opening drive element 131 can apply a smaller force to the first transmission member 1321, so that the lever assembly 1323 can apply a larger force to the contact member 1322, so that the door opening drive element 131 can drive the contact member 1322 to rotate clockwise with a smaller force, thereby driving the main shaft assembly 111 to rotate clockwise, which helps to reduce the requirements of the door opening drive component 130 for the performance of the door opening drive element 131 and reduce the cost of the door opening drive component 130.

[0080] In some embodiments, when the door closing drive assembly 120 drives the bottom door mechanism 110 to move to the shielding position, the lever assembly 1323 , the first transmission member 1321 and the door opening drive element 131 are driven by the contact member 1322 to return to the initial position.

[0081] The door closing drive assembly 120 drives the main shaft assembly 111 to rotate counterclockwise, thereby driving the contact piece 1322 to rotate counterclockwise. When the contact piece 1322 rotates counterclockwise to a certain angle, the contact piece 1322 will contact the lever assembly 1323, so that the end of the lever assembly 1323 located above the contact piece 1322 rises, thereby causing the end of the lever assembly 1323 connected to the first transmission member 1321 to descend, causing the first transmission member 1321 and the door opening drive element 131 to descend, thereby causing the lever assembly 1323, the first transmission member 1321 and the door opening drive element 131 to reset to their initial positions. With this design, the lever assembly 1323, the first transmission member 1321 and the door opening drive element 131 are all reset by the contact member 1322, and there is no need to reset by controlling the movement of the door opening drive element 131, thereby reducing the requirements for the door opening drive element 131 and the complexity of the control logic of the door opening drive element 131, so that the door opening drive element 131 can drive the first transmission member 1321 to rise until the lever 13231 presses the contact member 1322 to rotate until the lever assembly 1323 passes the dead point, which helps to save the cost of the door opening transmission mechanism 132.

[0082] The door opening drive element 131 can be an oil cylinder, an air cylinder, a screw nut, a scissor arm lifting mechanism, etc., which is not limited in this application.

[0083] In some embodiments, the door opening driving element 131 includes a driving rotating element 1311 and an eccentric wheel 1312 installed at the output end of the driving rotating element 1311 , and the first transmission member 1321 is disposed above the eccentric wheel 1312 .

[0084] The driving element 1311 can be a motor, and the eccentric wheel 1312 is fixedly connected to the output shaft of the motor. When the motor rotates, the eccentric wheel 1312 is driven to rotate. The first transmission member 1321 is arranged above the eccentric wheel 1312 and contacts the eccentric wheel 1312. When the eccentric wheel 1312 rotates counterclockwise under the drive of the motor, the eccentric wheel 1312 can contact the first transmission member 1321, driving the first transmission member 1321 to move upward, so that the lever assembly 1323 presses down the contact member 1322, driving the main shaft 1111 assembly to rotate past the dead point.

[0085] In some embodiments, the lever assembly 1323 includes a lever 13231 and a second transmission member 13232, the lever 13231 has a first end 13231a, a hinged end 13231b and a second end 13231c that are spaced apart, the hinged end 13231b is disposed between the first end 13231a and the second end 13231c, the first end 13231a is connected to the first transmission member 1321, and the hinged end 13231b is hinged to the box body 200; one end of the second transmission member 13232 is connected to the second end 13231c of the lever 13231, and the other end is located above the contact member 1322.

[0086] That is, along the length direction of the lever 13231, the first end 13231a, the hinged end 13231b and the second end 13231c are arranged in sequence and at intervals. The lever 13231 is connected to the first transmission member 1321 through the first end 13231a, connected to the second transmission member 13232 through the second end 13231c, and rotatably connected to the box body 200 through the hinged end 13231b. With this design, the first transmission member 1321 moves upward, driving the first end 13231a to move upward, causing the second end 13231c to move downward, thereby causing the second transmission member 13232 to move downward, causing the second transmission member 13232 to press the contact member 1322 located below it, causing the contact member 1322 to rotate clockwise. With this design, when the door closing drive assembly 120 drives the main shaft 1111 assembly to rotate counterclockwise, the contact member 1322 contacts the second transmission member 13232, driving the second transmission member 13232 to move upward, causing the second end 13231c of the lever 13231 to move upward, thereby causing the first end 13231a of the lever 13231 to move downward, causing the first transmission member 1321 to move downward, and the first transmission member 1321 presses the eccentric wheel 1312, causing the eccentric wheel 1312 to drive the rotating shaft of the door opening drive element 131 to rotate counterclockwise, thereby resetting the lever assembly 1323, the first transmission member 1321 and the door opening drive element 131.

[0087] In some embodiments, the distance from the first end 13231a to the hinged end 13231b is greater than the distance from the second end 13231c to the hinged end 13231b.

[0088] With this design, the driving element 1311 can use a smaller force to enable the second transmission member 13232 to drive the contact member 1322 to rotate, so that the main shaft component 111 passes the dead point, which helps to reduce the performance requirements of the door opening drive component 130 for the driving element 1311 and reduce the cost of the door opening drive component 130.

[0089] In some embodiments, the hopper box bottom door unit 100 includes two bottom door mechanisms 110 , and the door opening transmission mechanism 132 includes two contact members 1322 , the two contact members 1322 are respectively installed on the two bottom door mechanisms 110 , and the other ends of the second transmission member 13232 are respectively located on the two contact members 1322 .

[0090] One of the contact members 1322 is mounted on the main shaft 1111 of one of the bottom door mechanisms 110, and the other contact member 1322 is mounted on the main shaft 1111 of the other bottom door mechanism 110. The second transmission member 13232 is located on both contact members 1322 at the same time. With this design, when the first transmission member 1321 is driven by the eccentric wheel 1312 to rise, the second transmission member 13232 synchronously presses down the two contact members 1322. The door opening transmission mechanism 132 drives the two bottom door mechanisms 110 to open synchronously, thereby improving the opening efficiency of the bottom door mechanisms 110 and helping to increase the lowering rate of the material.

[0091] In some embodiments, the second transmission member 13232 includes a first connection portion 13233, a second connection portion 13234 and two third connection portions 13235, the second connection portion 13234 is connected to the second end 13231c of the lever 13231 and the middle of the first connection portion 13233; the two third connection portions 13235 are respectively fixed at both ends of the first connection portion 13233 and are respectively located above the two contact members 1322.

[0092] The first connection part 13233 is located below the lever 13231, the second connection part 13234 is arranged between the first connection part 13233 and the lever 13231, the upper end of the second connection part 13234 is connected to the second end 13231c of the lever 13231, and the lower end is connected to the first connection part 13233. Two third connection parts 13235 are respectively connected to one end of the first connection part 13233 and the other end of the first connection part 13233, one of the third connection parts 13235 is located above one of the contacts 1322, and the other third connection part 13235 is located above the other contact 1322. Specifically, the upper end of the third connection part 13235 is fixedly connected to the first connection part 13233, and the lower end of the third connection part 13235 is located above the contact 1322.

[0093] It should be noted that the two main shafts 1111 of the two bottom door mechanisms 110 are arranged in parallel. In some embodiments, the lever 13231 is arranged perpendicular to the main shaft 1111 of the bottom door mechanism 110, and the first connecting portion 13233 and the lever 13231 are arranged in parallel.

[0094] In some embodiments, the second connection portion 13234 is connected to the middle portion of the first connection portion 13233 .

[0095] In some embodiments, the second connection portion 13234 is rotatably connected to the second end 13231c of the lever 13231 around an axis parallel to the main shaft 1111, and the upper end of the first transmission member 1321 is rotatably connected to the first end 13231a of the lever 13231 around an axis parallel to the main shaft 1111. With such a design, the first transmission member 1321 can rotate around the first end 13231a of the lever 13231, and when the lever 13231 rotates around the hinge end 13231b, the first end 13231a of the lever 13231 will also rotate. With such a design, the upper end of the first transmission member 1321 can rotate along with the first end 13231a of the lever 13231, and the lower end of the first transmission member 1321 can be located on the eccentric wheel 1312, which helps to ensure that the lower end of the first transmission member 1321 is always located above the eccentric wheel 1312, thereby ensuring the stability of the first transmission member 1321. After such design, the second transmission member 13232 can rotate around the second end 13231c of the lever 13231. When the lever 13231 rotates around the hinged end 13231b, the second end 13231c of the lever 13231 will also rotate. After such design, the upper end of the second transmission member 13232 can rotate following the second end 13231c of the lever 13231, and the lower end of the second transmission member 13232, that is, the lower end of the third connecting part 13235 can always be located on the contact member 1322. The two third connecting parts 13235 can press the two contact members 1322 at the same time, thereby ensuring the stability of the second transmission member 13232 and ensuring that the two bottom door mechanisms 110 are opened synchronously.

[0097] The door closing drive element 121 drives the door closing transmission mechanism 122 to move. The door closing transmission mechanism 122 is connected to the main shaft component 111 of the bottom door mechanism 110. The door closing transmission mechanism 122 drives the main shaft component 111 to rotate counterclockwise, thereby causing the door panel component 112 of the bottom door mechanism 110 to rotate, so that the door panel component 112 covers the leakage port of the box body 200.

[0098] In some embodiments, the door closing transmission mechanism 122 includes a first gear 1221, a second gear 1222 and a first transmission chain 1223, the first gear 1221 is installed at the output end of the door closing drive element 121 and is driven by the door closing drive element 121; the second gear 1222 is installed on the bottom door mechanism 110; the first transmission chain 1223 is connected to the first gear 1221 and the second gear 1222.

With this design, the door closing driving element 121 drives the first gear 1221 to rotate, driving the first transmission chain 1223 to rotate, thereby driving the second gear 1222 to rotate counterclockwise, so that the main shaft 1111 of the bottom door mechanism 110 rotates counterclockwise, thereby causing the door panel assembly 112 of the bottom door mechanism 110 to rotate, so that the door panel assembly 112 shields the leakage port of the box body 200.

[0100] In some embodiments, the funnel box bottom door unit 100 includes two bottom door mechanisms 110, the second gear 1222 is installed on one of the bottom door mechanisms 110, and the door closing transmission mechanism 122 also includes a third gear 1224, a fourth gear 1225 and a second transmission chain 1226, the third gear 1224 is installed on the bottom door mechanism 110 where the second gear 1222 is located; the fourth gear 1225 is installed on the other bottom door mechanism 110; the second transmission chain 1226 is connected to the third gear 1224 and the fourth gear 1225.

[0101] The third gear 1224 is fixedly connected to the main shaft 1111 where the second gear 1222 is located, the fourth gear 1225 is fixedly connected to another main shaft 1111, and the second transmission chain 1226 is sleeved outside the third gear 1224 and the fourth gear 1225 and meshes with the third gear 1224 and the fourth gear 1225. With this design, the door closing drive element 121 drives the first gear 1221 to rotate counterclockwise, driving the first transmission chain 1223 and the second transmission chain 1226 to rotate counterclockwise synchronously, thereby causing the second gear 1222 and the fourth gear 1225 to rotate counterclockwise, causing the two main shafts 1111 to rotate counterclockwise, causing the door panels 112 of the two bottom door mechanisms 110 to rotate synchronously to cover the material leakage port, thereby improving the closing efficiency of the bottom door mechanism 110. It should be noted that when the main shaft 1111 rotates clockwise, the main shaft 1111 drives the second gear 1222 and the fourth gear 1225 to rotate clockwise, thereby driving the first transmission chain 1223 and the second transmission chain 1226 to rotate clockwise synchronously, and the output end of the door closing drive element 121 rotates clockwise.

[0102] In some embodiments, the door closing drive element 121 is a motor.
