Description

Technical Field

[0001] The invention relates to the technical field of brakes, and in particular to a roof-mounted bus air conditioner snowproof structure, a bus air conditioner and a bus. Background Art

[0002] The automobile air conditioning system is a device that realizes cooling, heating, ventilation and air purification of the air in the car. It can provide a comfortable riding environment for passengers, reduce the fatigue intensity of the driver, and improve driving safety. For buses, the air conditioner is generally installed on the top of the bus. In the snowy environment in cold areas, the air conditioner on the bus often cannot be turned on due to snow accumulation and ice. When the demand is high, the air conditioner cannot be used for heating in the car. At present, the snow prevention measures in low temperature environments are mainly in the system and control logic. When the air conditioner is started, the defrosting program is used to melt the snow or ice on the exposed heat exchanger through the heat emitted by the fin-tube heat exchanger itself. This method has a certain effect on solving the problem of snow accumulation and ice on the heat exchanger, but the external fan of the bus air conditioner is also exposed to the outside of the whole machine. When the temperature is lower or the snowing time is long, it is very likely that snow and ice will enter the external fan, causing the fan to be unable to rotate, so it cannot be turned on for heating. Therefore, an effective snow prevention structure is needed. Summary of the invention

[0003] In order to solve the above problems, the present invention provides a roof-mounted bus air conditioner snow-proof structure, and a bus air conditioner including the aforementioned roof-mounted bus air conditioner snow-proof structure, and also provides a bus including the aforementioned bus air conditioner.

[0004] The present invention is implemented by the following scheme:

[0005] A roof-mounted bus air conditioner snowproof structure is arranged on the top panel of the bus air conditioner and is used to prevent snow from the external fan of the bus air conditioner. The roof-mounted bus air conditioner snowproof structure includes a first support plate and a second support plate arranged in parallel on the top panel of the bus air conditioner, a first snowproof mechanism movably connected to the top of the first support plate and the second support plate, and a second snowproof mechanism movably connected to the top of the first support plate and the second support plate. The height of the top end surface of the first support plate and the height of the top end surface of the second support plate both gradually decrease from the middle to the two ends; the first snowproof mechanism and the second snowproof mechanism are symmetrically arranged with the center line of the top end surface of the first support plate as a reference.

[0006] Furthermore, the first snow protection mechanism and the second snow protection mechanism both include a snow protection plate and a driving assembly for driving the snow protection plate to move.

[0007] Furthermore, the driving assembly includes a rotating shaft arranged on the bottom surface of the snow-proof plate, two gears arranged at both ends of the rotating shaft, and a driving member arranged on one side of the snow-proof plate for driving the rotating shaft to rotate, and the two gears are both located between the first support plate and the second support plate, and the side of the first support plate facing the second support plate and the side of the second support plate facing the first support plate are both provided with racks corresponding to the gears.

[0008] Furthermore, the driving member is a motor, and the rotating shaft of the motor is connected to the rotating shaft through a coupling.

[0009] Furthermore, the roof-mounted bus air conditioner snow protection structure also includes a first wind shield and a second wind shield arranged on the top panel of the bus air conditioner, and the first wind shield, the second wind shield, the first support plate, and the second support plate form a rectangular space.

DETAILED DESCRIPTION

[0025] To facilitate those skilled in the art to understand the present invention, the present invention will be further described in detail below in conjunction with specific embodiments and drawings.

[0026] Reference Figures 1 to 6 The present invention provides a roof-mounted passenger air conditioner snowproof structure, which is arranged on the top panel of the passenger air conditioner and is used to prevent snow from the external fan of the passenger air conditioner. The roof-mounted passenger air conditioner snowproof structure includes a first support plate 1 and a second support plate 2 arranged in parallel on the top panel of the passenger air conditioner, a first snowproof mechanism 3 movably connected to the top of the first support plate 1 and the second support plate 2, and a second snowproof mechanism 4 movably connected to the top of the first support plate 1 and the second support plate 2. The height of the top end surface of the first support plate 1 and the height of the top end surface of the second support plate 2 are gradually reduced from the middle to the two ends; the first snowproof mechanism 3 and the second snowproof mechanism 4 are symmetrically arranged with the center line of the top end surface of the first support plate 1 as the reference, which is equivalent to taking the connecting line of the middle position of the first support plate 1 and the second support plate 2 as the reference. The height of the top end surface of the first support plate 1 and the height of the top end surface of the second support plate 2 are gradually reduced from the middle to the two ends, that is, a two-side slope structure is formed, the first snowproof mechanism 3 is arranged on one side of the slope, and the second snowproof mechanism 4 is arranged on the other side of the slope.

[0027] The first snow protection mechanism 3 and the second snow protection mechanism 4 each include a snow protection plate 31 and a driving assembly 32 for driving the snow protection plate 31 to move. Driven by the driving assembly 32, the snow protection plate 31 of the first snow protection mechanism 3 and the snow protection plate 31 of the second snow protection mechanism 4 can be opened to both sides or closed to the middle.

[0028] The driving assembly 32 includes a rotating shaft 321 disposed on the bottom surface of the snow-proof plate 31, two gears 322 disposed at both ends of the rotating shaft 321, and a driving member 323 disposed on one side of the snow-proof plate 31 for driving the rotating shaft 321 to rotate, and the two gears 322 are both located between the first support plate 1 and the second support plate 2, and the side of the first support plate 1 facing the second support plate 2 and the side of the second support plate 2 facing the first support plate 1 are both provided with a rack 5 corresponding to the gear 322. In specific implementation, the rotating shaft 321 and the driving member 323 can be connected to the snow-proof plate 31 through a connecting member. At the same time, a limiting structure (such as a limiting groove, etc.) can be provided between the snow-proof plate 31 and the first support plate 1, and between the snow-proof plate 31 and the second support plate 2 to prevent the snow-proof plate 31 from falling out.

[0029] In this embodiment, four racks 5 are provided, of which two are provided on the side of the first support plate 1 facing the second support plate 2, and both are provided along the edge close to the top end face of the first support plate 1, that is, they are provided at an angle. Two racks are provided on the side of the second support plate 2 facing the first support plate 1, and both are provided along the edge close to the top end face of the second support plate 2, that is, they are provided at an angle. Thus, the snow protection plate 31 of the first snow protection mechanism 3 and the snow protection plate 31 of the second snow protection mechanism 4 can realize opening and closing actions.

[0030] like Figure 6 In order to ensure the smooth opening of the snowboard 31, the size and inclination of the structure have certain requirements, such as Figure 6 As shown, L×tanθ≦H must be satisfied, where L represents the maximum horizontal distance that the single-side snow guard 31 can be opened, θ is the tilt angle, and H is the distance between the bottom of the snow guard 31 and the bottom of the entire device when the snow guard 31 is closed. The height of the snow guard 31 descending along the rack 5 during the opening process must be less than or equal to H, so that the snow guard 31 does not hit the surface of the air conditioner panel and the snow guard 31 can be fully opened.

[0031] The driving member 323 is a motor, and the rotating shaft 321 of the motor is connected to the rotating shaft 321 through a coupling 324 .

[0032] The roof-mounted bus air conditioner snowproof structure also includes a first windshield 6 and a second windshield 7 arranged on the top panel of the bus air conditioner, and the first windshield 6, the second windshield 7, the first support plate 1, and the second support plate 2 form a rectangular space to surround the external fan. The first windshield 6 and the second windshield 7 can effectively prevent wind and snow from blowing in when the vehicle is moving.

[0033] The roof-mounted bus air conditioner snow protection structure also includes a plurality of first limit blocks 8 for limiting the snow protection plate 31 of the first snow protection mechanism 3, and a plurality of second limit blocks 9 for limiting the snow protection plate 31 of the second snow protection mechanism 4. The first limit blocks 8 are arranged on the side of the bus air conditioner top panel close to the first snow protection mechanism 3, and the second limit blocks 9 are arranged on the side of the bus air conditioner top panel close to the second snow protection mechanism 4.

[0034] The first support plate 1 and the second support plate 2 are arranged along the traveling direction of the bus.

[0035] In actual use, the motor drives the shaft 321 to rotate, and the gear 322 on the shaft 321 cooperates with the rack 5, so that the snow guard 31 can move along the inclined rack 5 to achieve the opening and closing action. When the bus air conditioner is turned off, the snow guard 31 of the first snow guard mechanism 3 and the snow guard 31 of the second snow guard mechanism 4 are closed to prevent snow from falling into the air outlet from top to bottom, and the top tilt helps to reduce the accumulation of snow on the baffle.

[0036] The present invention also provides a bus air conditioner, comprising the aforementioned roof-mounted bus air conditioner snow protection structure.

[0037] The present invention also provides a bus, comprising the aforementioned bus air conditioner.

When the air conditioner is turned off, the snow protection plate of the first snow protection mechanism and the snow protection plate of the second snow protection mechanism can be closed under the drive of the driving assembly, thereby effectively solving the problem that the bus air conditioner cannot be used due to snowfall. On the other hand, the two-sided slope structure allows snowfall to slide naturally, which helps to reduce the accumulation of snow on the baffle.
