[0037] The embodiments of the utility model will be described in detail below with reference to the drawings.

[0038] Embodiment:

[0039] Referring to Figure 1 , Figure 2 , Figure 3 and Figure 4 , the embodiment discloses a fresh air system in an elevator car, comprising a partition plate 10, a cover plate 20, a baffle 30, a driving assembly 40 and a fan 50, wherein the fan 50 is arranged on the top of the outside of the car 60 and delivers airflow into the car 60. The partition plate 10 is located in the car 60 and is arranged on the top of the car 60 and keeps a certain distance with the top of the car 60, the cover plate 20, the baffle 30 and the driving assembly 40 are all arranged on the partition plate 10, and the position of the cover plate 20 and the baffle 30 is controlled through the driving assembly 40, so as to realize the direction of the airflow of the cover plate 20.

[0040] Specifically, a hole is formed on the top of the car 60, and the fan 50 is installed on the hole, so that the fan 50 delivers airflow into the car 60 from the hole.

[0041] The partition plate 10 is arranged in the car 60, and the two sides of the plate are connected with the inner wall of the car 60 respectively, and there is a gap between the two ends of the partition plate 10 and the two sides of the car 60, the gap is an air duct 11, so that there is an air duct 11 on each side of the car 60. Two groups of air grooves 12 are arranged on the partition plate 10, each group of air grooves 12 comprises a plurality of strip-shaped grooves, the two groups of air grooves 12 are respectively symmetrical along the length direction of the partition plate 10 and are close to the middle part of the partition plate 10, so that the two groups of air grooves 12 are located in the middle part of the car 60.

[0042] The cover plate 20 has two, and the two cover plates 20 correspond to a group of air grooves 12 respectively, the area of the cover plate 20 is greater than the area of the air groove 12, the two cover plates 20 are power-connected with the driving assembly 40 and are driven by the driving assembly 40 to move close to or away from each other, when the two cover plates 20 move close to each other, the two groups of air grooves 12 on the partition plate 10 are opened, when the two cover plates 20 move away from each other, the air groove 12 is closed.

[0043] The baffle 30 also has two, and the two baffles 30 are rotationally arranged on the two ends of the partition plate 10 respectively, so that the two baffles 30 can completely close the two air ducts 11. In addition, the two baffles 30 are also power-connected with the driving assembly 40, and when the driving assembly 40 drives the two cover plates 20 to move close to each other (i.e. when the air groove 12 is opened), the two baffles 30 close the two air ducts 11 (i.e. the air duct 11 is closed), when the driving assembly 40 drives the two cover plates 20 to move away from each other (i.e. when the air groove 12 is closed), the two baffles 30 open the two air ducts 11.

[0044] Therefore, the driving assembly 40 has two outputs, and the two outputs are used to drive the synchronous movement of the two cover plates 20 and the two baffle plates 30.

[0045] In this embodiment, first, a partition plate 10 is arranged on the top of the car 60, and a gap is kept between the partition plate 10 and the top of the car 60, so that the airflow output by the fan 50 on the top of the car 60 flows into the gap. Then, a plurality of air grooves 12 are designed on the partition plate 10, and gaps are kept between the two ends of the partition plate 10 and the two sides of the car 60 to form air ducts 11, so that the airflow output by the fan 50 can flow out of the air grooves 12 or the air ducts 11.

[0046] Then, the baffle plate 30 and the cover plate 20 are designed, and the driving assembly 40 is used to drive the baffle plate 30 and the cover plate 20, so that only one of the air grooves 12 and the air ducts 11 is in an open state, thereby selectively making the airflow of the fan 50 output from the air grooves 12 or the air ducts 11.

[0047] In this embodiment, the air grooves 12 are designed near the middle of the car 60, and the air ducts 11 are on the two sides of the car 60, so that by controlling the path of the airflow, the airflow is made to flow out of the air ducts 11 or the air grooves 12 in different seasons, and the system has the advantage of meeting the needs of different seasons.

[0048] In one specific embodiment:

[0049] A guide pipe 51 is arranged on the air inlet of the fan 50, and the end of the guide pipe 51 away from the fan 50 is arranged in a horizontal direction. Through this design, the air inlet of the fan 50 is distributed in a horizontal direction, thereby avoiding the influence of the airflow generated by the movement of the car 60 on the fan 50 during the ascending or descending process of the elevator car 60.

[0050] In another specific embodiment:

[0051] Referring to Figure 3 and Figure 4 , the driving assembly 40 includes a motor 41, a screw rod 42, a connecting piece 43, a connecting ring 44, a connecting rod 45, a pull rod 46, and a hinged column 47.

[0052] Specifically, the motor 41 is fixedly arranged in the middle of the partition plate 10, the screw rod 42 has two, and the two screw rods 42 are respectively arranged along the length direction of the partition plate 10, and the screw rod 42 is rotatably arranged on the partition plate 10. The two screw rods 42 are coaxially distributed, one end of the two screw rods 42 is close to each other, and the output shaft of the motor 41 is connected to the one end of the two screw rods 42 through a set of bevel gears.

[0053] The motor 41 output shaft and the screw rod 42 are perpendicular, the bevel gear has three, which are respectively arranged at the motor 41 output shaft and the two screw rod 42 end parts.

[0054] The two screw rods 42 respectively pass above the two cover plates 20, and one connecting piece 43 is arranged on each cover plate 20, the connecting piece 43 has a threaded hole which matches the screw rod 42. Thus, when the screw rod 42 is driven to rotate by the motor 41 output shaft and the bevel gear, the cover plate 20 can be directly driven to slide on the partition plate 10 through the connecting piece 43, thereby realizing opening or closing the air slot 12.

[0055] In addition, the screw rod 42 end part is matched with a connecting ring 44, and the connecting ring 44 interior is also a threaded hole. A connecting rod 45 which is perpendicular to the screw rod 42 is arranged on each side of the connecting ring 44, the connecting rod 45 is rotationally connected with one end of a pull rod 46, and the connecting rod 45 is perpendicular to the pull rod 46.

[0056] A hinge post 47 is vertically arranged on the side of the baffle 30, and the hinge post 47 top end is rotationally connected with the other end of the pull rod 46.

[0057] In the embodiment, the screw rod 42 has two threads with opposite screw directions, one of which matches the connecting ring 44, and the other of which matches the connecting piece 43.

[0058] The working principle of the embodiment is that when the motor 41 drives the screw rod 42 to rotate, the moving direction of the connecting rod 45 and the moving direction of the connecting ring 44 are opposite, so that the moving directions of the cover plate 20 and the baffle 30 on the same side of the motor 41 are opposite, thereby realizing that when the air duct 11 is opened, the air slot 12 is in a closed state, and when the air slot 12 is opened, the air duct 11 is in a closed state.

[0059] The above-described embodiments only express the specific implementation of the present application, and the description is more specific and detailed, but it cannot be understood as limiting the patent scope of the present application. It should be pointed out that for ordinary skilled in the art, without departing from the concept of the present application, a number of modifications and improvements can be made, which all belong to the protection scope of the present application.
