[0042] Combination Figures 1 to 5 As shown in the drawings, the utility model provides a chassis assembly, including bottom plate 100, water hitting piece 200, driving part 300 and protective cover 400.

[0043] The bottom plate 100 is provided with a water hitting groove 110 and a mounting groove 120 which are independent of each other. The water hitting piece 200 is arranged in the water hitting groove 110. The driving part 300 is arranged in the mounting groove 120, and the output shaft of the driving part 300 extends out of the mounting groove 120 and extends into the water hitting groove 110, and is drivingly connected with the water hitting piece 200. The protective cover 400 is buckled on the mounting groove 120 and covers the driving part 300, and the protective cover 400 is configured as a cover body with a circular arc top surface and is clamped with the mounting groove 120.

[0044] Optionally, the bottom plate 100 is configured as a flat plate, and a circumferential edge portion 101 extending upward is arranged around the circumference of the bottom plate 100. The outdoor heat exchanger is arranged on the bottom plate 100, and a large amount of heat is released from the outdoor heat exchanger when the mobile air conditioner operates in the cooling mode. The outdoor heat exchanger needs to be cooled to absorb the heat of the outdoor heat exchanger, so as to ensure the normal circulation of the refrigerant. A water striking groove 110 is arranged on the bottom plate 100 corresponding to the outdoor heat exchanger, and a water striking member 200 is arranged in the water striking groove 110. The condensate water in the water striking groove 110 is stirred by the water striking member, so that the condensate water is thrown to the surface of the outdoor heat exchanger, thereby achieving the cooling of the outdoor heat exchanger.

[0045] Optionally, the water striking member 200 can be a water striking wheel. Specifically, the outdoor heat exchanger is configured with a plurality of heat exchange fin groups arranged at intervals along the width direction of the outdoor heat exchanger. A plurality of water striking wheel blades are arranged coaxially between two adjacent heat exchange fin groups. That is, the plurality of water striking wheel blades rotate synchronously. Optionally, the water striking member 200 can also be rod-shaped, or can be other structures capable of stirring the condensate water to throw the condensate water to the surface of the outdoor heat exchanger.

[0046] Optionally, the driving member 300 is arranged in the mounting groove 120. By arranging the driving member 300 and the water striking member 200 in the mutually independent mounting groove 120 and water striking groove 110 respectively, the driving member 300 and the water striking member 200 are separated to avoid water entering the driving member 300. Optionally, the driving member 300 is a driving motor, and the output shaft of the driving motor is arranged coaxially with the water striking wheel. The output shaft extends out of the mounting groove 120 and extends into the water striking groove 110, thereby achieving the driving connection between the driving member 300 and the water striking member 200, so as to achieve the driving of the water striking wheel 200.

[0047] Optionally, in order to facilitate the installation of the driving member 300, the upper end of the mounting groove 120 is open. In this way, during the movement of the water striking member 200 driven by the driving member 300, the stirred condensate water will splash out of the water striking groove 110 and splash onto the driving member 300. In order to avoid failure of the driving member 300, a protective cover 400 is arranged at the top end of the mounting groove 120. The protective cover 400 covers the driving member 300 and is buckled at the top end of the mounting groove 120. The protective cover 400 is clamped with the mounting groove 120, so as to facilitate the installation, maintenance or replacement of the driving member.

[0048] Optionally, the protective cover 400 is configured as a semicircular cover. In this way, if the condensate water splashes onto the outer surface of the protective cover 400, it can slide downward along the arc surface under the action of gravity, thereby avoiding the accumulation of condensate water on the surface of the protective cover 400. In addition, such arrangement can also match the shape of the driving motor as much as possible, thereby reducing the occupied space.

[0049] Optionally, the outer surface of the protective cover 400 is coated with a hydrophobic coating to accelerate the sliding of the condensate water.

[0050] Alternatively, the outer surface of the protective cover 400 is not coated with a hydrophobic coating.

[0051] Optionally, the lower end of the protective cover 400 is at least matched in shape with the upper end of the mounting groove 120 to avoid condensate water from flowing in.

[0052] Optionally, the bottom groove wall of the mounting groove 120 is matched in shape with the driving motor.

[0053] In the above technical solution, by buckling the semicircular protective cover 400 above the water splashing groove 110, in the case of condensate water splashing onto the protective cover 400, it can drip down to the bottom plate 100 along the protective cover 400, thereby achieving the protection of the driving member 300, avoiding the safety problems such as short circuit of the driving member 300 during driving the water splashing member 200 to run. The protective cover 400 not only shields the driving member 300, but also guides the condensate water, thereby improving the safety of the driving member 300 and ensuring the normal operation of the water splashing member 200. The protective cover 400 is clamped with the mounting groove 120, which can quickly realize the maintenance or replacement of the driving member 300 when the driving member 300 fails, thereby ensuring the use of the mobile air conditioner.

[0055] By making the height of the lower end of the side wall of the protective cover 400 lower than the height of the upper end of the groove side wall of the mounting groove 120, the condensate water can be prevented from entering the mounting groove 120 through the gap therebetween, thereby reducing the corrosion of the driving member 300.

[0056] Specifically, the lower end of the side wall of the protective cover 400 is sleeved on the outer surface of the mounting groove 120, i.e., the inner surface of the lower end of the side wall of the protective cover 400 abuts against the outer surface of the groove side wall of the mounting groove 120. In this way, the condensate water can be prevented from penetrating into the mounting groove 120 through the gap therebetween, thereby ensuring the dryness of the space in the mounting groove 120.

[0059] Through the arrangement of the heat dissipation opening, the heat dissipation effect of the driving member 300 can be improved, and the overheating of the driving member 300 in the closed space can be avoided.

[0060] Optionally, a stop piece is arranged around the circumference of the heat dissipation opening, and the included angle between the stop piece and the outer surface of the protective cover 400 is less than 180°, that is, the stop piece is bent upward, so as to avoid the condensed water on the outer surface of the protective cover 400 from entering the mounting groove 120 through the heat dissipation opening.

[0061] Alternatively, the heat dissipation opening is not arranged.

[0064] Through the clamping cooperation of the first clamping member 510 and the second clamping member, the detachable connection of the protective cover 400 and the mounting groove 120 can be realized, and the quick installation or disassembly of the protective cover 400 can be realized, so as to facilitate the maintenance and replacement of the driving member 300.
