[0025] The present invention will be further described below in conjunction with embodiments, but it is not limited to the content in the specification.

[0026] As shown Figures 1 to 6 in the figure, the present invention discloses an outer cover structure applied to an outdoor unit of a vehicle air conditioner, including: a housing 1, the housing 1 covers the outdoor unit of the vehicle air conditioner, and an air inlet 11 is provided on the housing 1; a baffle 2, the baffle 2 is movably arranged at the air inlet 11, and the baffle 2 has a first state of closing the air inlet 11 and a second state of retracting into the housing 1 to open the air inlet 11; a reset mechanism 3, the reset mechanism 3 is arranged between the housing 1 and the baffle 2, and the reset mechanism 3 can switch the baffle 2 from the second state to the first state. The reset mechanism 3 can keep the baffle 2 closed to the air inlet 11, open the air inlet 11 during the operation of the outdoor unit of the vehicle air conditioner, enable the outside air to enter the fuselage, and the outdoor unit of the vehicle air conditioner operates normally; close the air inlet 11 during the shutdown state of the outdoor unit of the vehicle air conditioner, effectively avoiding the situation that impurities such as insects and rainwater enter the fuselage and cause damage to the circuits and components.

[0027] In order to switch the baffle 2 to the second state, as an implementation manner, the outdoor unit of the vehicle air conditioner includes a blower, the blower is arranged in the housing 1, and the blower can generate negative pressure in the housing 1 to switch the baffle 2 from the first state to the second state. When the outdoor unit of the vehicle air conditioner works, the blower rotates and blows the gas in the outdoor unit of the vehicle air conditioner to the outside, so that negative pressure is generated inside the outdoor unit of the vehicle air conditioner. Since the baffle 2 is movable, under the action of this negative pressure, the baffle 2 starts to move towards the inside of the housing 1 to open the air inlet 11, realizing the automatic opening of the air inlet 11. When the blower stops working, the negative pressure inside the outdoor unit of the vehicle air conditioner gradually decreases, and the baffle 2 gradually switches to the first state under the action of the reset mechanism 3, and finally closes the air inlet 11, effectively avoiding the situation that impurities such as insects and rainwater enter the fuselage and cause damage to the circuits and components.

[0028] Moreover, with the magnitude of the negative pressure generated by the blower, the position of the baffle 2 can be adjusted to adjust the opening degree of the air inlet 11, so as to ensure the normal operation of the outdoor unit of the vehicle air conditioner.

[0029] Preferably, an air outlet 12 is provided on the housing 1, and the blower is located near the air outlet 12.

[0030] Preferably, when the baffle 2 is in the first state, the baffle 2 is flush with the side surface of the housing having the air inlet 11, improving the appearance beauty of the outer cover structure.

[0031] The outer cover structure further includes an abutting member 4, the abutting member 4 is arranged inside the housing 1, one end of the reset mechanism 3 is arranged on the abutting member 4, and the other end is arranged on the baffle 2. The abutting member 4 facilitates the installation of the reset mechanism 3 and ensures the reliable movement of the baffle 2.

[0032] Specifically, a through hole 41 is arranged on the abutting member 4, an installation post 21 is arranged on the baffle 2, the installation post 21 is movably arranged inside the through hole 41, and the reset mechanism 3 is sleeved on the installation post 21. Taking the reset mechanism 3 as a spring for example, the spring is sleeved inside the installation post 21. When the baffle 2 moves to open the air inlet 11, the installation post 21 moves inside the through hole 41, and at the same time the spring is compressed in the defined direction of the installation post 21 to prepare for the baffle 2 to close the air inlet 11.

[0033] A first guiding and mating part 13 is arranged on the housing 1, a second guiding and mating part 22 is arranged on the baffle 2, and the first guiding and mating part 13 and the second guiding and mating part 22 cooperate with each other. As Figure 4 shown, the first guiding and mating part 13 is a guiding groove, the second guiding and mating part 22 is a guiding post, and the guiding post is movably arranged inside the guiding groove.

[0034] To avoid the need for a large negative pressure to drive due to the too large area of the baffle 2, the outer cover structure further includes grid ribs 5, the grid ribs 5 divide the air inlet 11 into multiple air inlet parts, the baffle 2 includes multiple blocking blocks 23, the blocking blocks 23 correspond to the air inlet parts one by one, and when the baffle 2 is in the second state, the baffle 2 can open the corresponding air inlet part.

[0035] The baffle 2 further includes a frame 24, all the blocking blocks 23 are arranged on the frame 24, and the reset mechanism 3 is arranged between the housing 1 and the frame 24. Ensure the synchronous movement of all the blocking blocks 23 and improve the closing reliability of the blocking blocks 23 for the air outlet.

[0036] There is a spacing between the blocking block 23 and the edge of the air inlet part, and the range of the spacing is 0.1 mm to 0.5 mm. Avoid interference between the blocking block 23 and the air inlet part and affect the reliability of the outer cover structure.

[0037] The number of the air inlets 11 is at least two, and the air inlets 11 correspond to the baffle 2 one by one.

[0038] Another aspect of the present invention provides a recreational vehicle air conditioner, including the above-mentioned outer cover structure.

[0039] As an implementation manner, the RV air conditioner includes a housing, and the outer cover structure is disposed outside the housing. That is, an outer cover structure can be directly provided on the existing RV air conditioner to prevent insects and foreign objects.

[0040] As another implementation manner, the RV air conditioner includes a housing, and the housing is constituted by the outer cover structure. The housing of the existing RV air conditioner can also be replaced with an outer cover structure.

[0041] Obviously, the above-mentioned implementation manners of the present invention are only examples for clearly explaining the present invention, rather than limitations on the implementation manners of the present invention. For those of ordinary skill in the art, other different forms of changes or variations can be made based on the above description. It is impossible to enumerate all the implementation manners here. Any obvious changes or variations derived from the technical solutions of the present invention are still within the protection scope of the present invention.
