[0030] Please refer to Figures 1 to 4 , the present utility model discloses a car structure, which includes a car chamber 1, a car door 2 and a car door driving assembly 3. The car chamber 1 is a cubic structure provided with a ventilation device, and an opening is provided on one surface of the car chamber 1. The car door 2 is cooperatively arranged at the opening of the car chamber 1. The car door driving assembly 3 is arranged on the outer wall surface of the top side of the car chamber 1, and the car door driving assembly 3 is drivingly connected to the car door 2 to drive the car door 2 to perform opening and closing movements relative to the car chamber 1.

[0031] Specifically, the car door driving assembly 3 includes a microswitch group 31, and the microswitch group 31 is arranged on the outer wall surface of the top side of the car chamber 1 corresponding to the closing state position and the opening state position of the car door 2. Thus, when the car door driving assembly 3 drives the car door 2 to perform opening and closing movements relative to the opening of the car chamber 1, the microswitch group 31 can mark and limit the starting and ending positions of the movement of the car door 2, so as to ensure the sealing effectiveness of the car door 2 to the car chamber 1.

[0032] Furthermore, the car door 2 includes a first door leaf 21 and a second door leaf 22. The first door leaf 21 and the second door leaf 22 are correspondingly matched with the opening of the car chamber 1 in a split-opening manner. That is, the first door leaf 21 and the second door leaf 22 are respectively arranged on both sides of the opening of the car chamber 1 and perform opposite and away movements in actual application. When the first door leaf 21 and the second door leaf 22 perform opposite movements and join at the opening of the car chamber 1, at this time, the car door 2 touches the microswitch group 31 at the end position of the closing movement of the car door 2, and the car chamber 1 and the car door 2 are in a cooperative closing state; when the first door leaf 21 and the second door leaf 22 perform away movements and move to the end position of the opening movement of the car door 2 preset by the microswitch group 31, the microswitch group 31 controls the first door leaf 21 and the second door leaf 22 to stop moving, and at this time, the car chamber 1 and the car door 2 are in a cooperative opening state.

[0033] Furthermore, the microswitch group 31 includes a first microswitch 311 and a second microswitch 312. The first microswitch 311 is correspondingly arranged at the end position of the opening movement of the car door 2. When the car door 2 opens relative to the car chamber 1, until the first microswitch 311 is touched, the car door 2 stops moving, thereby maintaining the open state of the car chamber 1; the second microswitch 312 is correspondingly arranged at the end position of the closing movement of the car door 2. When the car door 2 closes relative to the car chamber 1, until the second microswitch 312 is touched, the car door 2 stops moving, thereby maintaining the closed state of the car chamber 1.

[0034] Furthermore, the door drive assembly 3 also includes a drive motor 32, a first synchronous pulley 33, a second synchronous pulley 34 and an annular toothed belt 35. The first synchronous pulley 33 is arranged on the side of the first door leaf 21 facing away from the second door leaf 22; the second synchronous pulley 34 is arranged on the side of the second door leaf 22 facing away from the first door leaf 21; the annular toothed belt 35 is sleeved on the outside of the first synchronous pulley 33 and the second synchronous pulley 34, so that the first synchronous pulley 33 and the second synchronous pulley 34 are connected through the annular toothed belt 35; the drive motor 32 is installed on the top side outer wall surface of the cabin chamber 1, and the output end of the drive motor 32 is driven and connected to the first synchronous pulley 33, so that the drive motor 32 can drive the annular toothed belt 35 to roll.

[0035] Specifically, the first door leaf 21 is connected to the bottom section of the annular toothed belt 35, and the second door leaf 22 is connected to the top section of the annular toothed belt 35, so that when the drive motor 32 drives the annular toothed belt 35 to roll, it can synchronously drive the first door leaf 21 and the second door leaf 22 to perform reciprocating motion toward and away from each other, thereby realizing the opening and closing functions of the first door leaf 21 and the second door leaf 22.

[0036] Furthermore, the first microswitch 311 is arranged at a preset position on the side of the first door leaf 21 facing away from the second door leaf 22. When the car door 2 is opened, the first door leaf 21 and the second door leaf 22 move away from each other to the end position of the opening movement. At this time, the first door leaf 21 touches the first microswitch 311, thereby controlling the drive motor 32 to stop running, thereby maintaining the open state of the first door leaf 21 and the second door leaf 22.

[0037] Furthermore, the second microswitch 312 is arranged at a preset position on the top side of the first door leaf 21. When the car door 2 is closed, the first door leaf 21 and the second door leaf 22 move toward each other to the end position of the closing movement. At this time, the first door leaf 21 touches the second microswitch 312, thereby controlling the drive motor 32 to stop running, thereby maintaining the open state of the first door leaf 21 and the second door leaf 22.

[0038] Furthermore, the car door drive assembly 3 further includes a mounting plate 36 which is arranged on the top side of the car door 2 and supports the first microswitch 311, the second microswitch 312, the drive motor 32, the first synchronous pulley 33 and the second synchronous pulley 34. Specifically, the first microswitch 311 is arranged at the end of the mounting plate 36 corresponding to the first door leaf 21; the second microswitch 312 is arranged on the top surface of the mounting plate 36 corresponding to the first door leaf 21; the first synchronous pulley 33 and the second synchronous pulley 34 are respectively rotatably mounted at both ends of the mounting plate 36; the drive motor 32 is mounted on one side surface of the mounting plate 36 corresponding to the first synchronous pulley 33 and is drivingly connected to the first synchronous pulley 33.

[0039] Furthermore, the first door leaf 21 is provided with a first connecting plate 211 which is arranged at the top end of the first door leaf 21, and the top end of the first connecting plate 211 is cooperatively connected to the bottom side section of the endless toothed belt 35. Specifically, the first connecting plate 211 is provided with a trigger plate 2111 which is arranged on one side surface of the first connecting plate 211 and extends a preset distance in the top side direction. When the first door leaf 21 is in the closed state, the trigger plate 2111 touches the second microswitch 312.

[0040] Furthermore, the second door leaf 22 is provided with a second connecting plate 221 which is arranged at the top end of the second door leaf 22, and the top end of the second connecting plate 221 is cooperatively connected to the top side section of the endless toothed belt 35.

[0041] Furthermore, a chute 361 is arranged on the side of the mounting plate 36 facing the car door 2; correspondingly, a plurality of first pulleys 2112 are rotatably mounted on the first connecting plate 211; a plurality of second pulleys 2211 are rotatably mounted on the second connecting plate 221; the plurality of first pulleys 2112 and the plurality of second pulleys 2211 are respectively cooperatively connected to the chute 361, thereby further improving the sliding stability between the first door leaf 21 and the second door leaf 22 and the mounting plate 36.

[0042] In summary, the car structure disclosed by the present utility model drives the car door to perform opening and closing movements relative to the car chamber through the car door drive assembly, thereby improving the stability of the opening and closing of the car door. Among them, the microswitch group is arranged on the outer wall surface of the top side of the car chamber corresponding to the closing state position point and the opening state position point of the car door, so that when the car door drive assembly drives the car door to perform opening and closing movements relative to the opening of the car chamber, the microswitch group can mark and limit the starting and ending position points of the movement of the car door, thereby ensuring the sealing effectiveness of the car door to the car chamber.

[0043] The technical features of the above-described embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as within the scope described in this specification.
