As shown in fig. 1, the casing 10 has a key panel 11, and the key panel 11 is provided with a key hole 12.

Fig. 2 is a schematic view of a key panel 11 according to an embodiment of the disclosure. As shown in fig. 1 and 2, the key hole 12 penetrates the key panel 11, the flexible key 2 is provided in the key hole 12, and at least a part of the flexible key 2 is connected to an inner wall of the key hole 12.

As shown in fig. 1, the circuit board 30 has a mechanical switch 31 thereon, the mechanical switch 31 faces the key panel 11, and the mechanical switch 31 is opposite to the flexible key 2.

The disclosed embodiment provides a controller of a parking air conditioner including: the key comprises a shell 10 and a circuit board 30, wherein the circuit board 30 is arranged in the shell 10, a key hole 12 is arranged on a key panel 11 of the shell 10, a flexible key 2 is arranged in the key hole 12, and the flexible key 2 is connected with the inner wall of the key hole 12. The circuit board 30 is also provided with a mechanical switch 31, and the mechanical switch 31 faces the key panel 11. Thus, when a user presses the flexible key 2 on the key panel 11, the flexible key 2 is elastically deformed, and after moving a certain distance, the flexible key 2 abuts against the mechanical switch 31, so that the mechanical switch 31 is triggered to act, and the parking air conditioner is controlled to be started. Because the flexible key 2 has a certain flexibility, the flexible key 2 can automatically reset under the action of elasticity after the user presses the flexible key. Compared with the scheme that the elastic components such as springs are adopted to realize the key resetting in the related technology, partial parts in the controller are removed, the key structure of the controller is simplified, the problem that the keys are prone to failure is solved, and the parking air conditioner can stably work.

Optionally, the flexible key 2 is made of polyvinyl chloride. Among them, Polyvinyl chloride (PVC for short) is a high molecular material, and has good toughness and stability. The flexible key 2 made of polyvinyl chloride can be elastically deformed after being pressed, and automatically recovers under the action of elastic force after the pressing is finished, so that the aim of braking and resetting the flexible key 2 is fulfilled.

Alternatively, as shown in fig. 2, the flexible key 2 and the key panel 11 are integrally formed.

Illustratively, the flexible key 2 and the key panel 11 are integrally injection molded. That is, the entire key panel 11 is of a unitary structure. The flexible key 2 is connected in the key hole 12 by cutting off a part of the area surrounding the flexible key 2 on the key panel 11, so that the flexible key 2 can have the function of pressing deformation, and the mechanical switch 31 can be triggered to act when being pressed.

Illustratively, the housing 10 and the key panel 11 may also be integrally formed, i.e. the entire housing 10 is integrally injection molded.

In the embodiment of the present disclosure, the Circuit Board 30 may be a PCBA (Printed Circuit Board Assembly). The mechanical switch 31 is welded on the circuit board 30, and the mechanical switch 31 is electrically connected with the electronic device on the circuit board 30, so that after the mechanical switch 31 is triggered and actuated by the flexible key 2, the circuit board 30 can transmit signals to control the parking air conditioner to be started or closed.

Alternatively, as shown in fig. 1, the flexible key 2 includes a touch plate 21 and a touch protrusion 22, the touch plate 21 is connected to the inner wall of the key hole 12, the touch protrusion 22 is located on the plate surface of the touch plate 21, and the touch protrusion 22 is located between the touch plate 21 and the mechanical switch 31 and opposite to the mechanical switch 31.

The touch panel 21 is connected to an inner wall of the key hole 12, so that the touch panel 21 can be elastically deformed relative to the inner wall of the key hole 12 after being pressed by a user. And set up the touching projection 22 between touch panel 21 and mechanical switch 31, set up touching projection 22 as and opposite to mechanical switch 31, in order to guarantee while pressing the touch panel 21, can support the mechanical switch 31 action through touching projection 22, improve the reliability of the tough key set 2.

Wherein, the area of the touch part 211 is larger than that of the connection part 212, i.e. the size of the connection part 212 is smaller. Thus, when the touch portion 211 is pressed, the user can touch the connection portion 212 to generate elastic deformation without applying a large force, so as to push the touch plate 21 to act against the mechanical switch 31.

Fig. 3 is a schematic view of another key panel 11 provided in the embodiment of the present disclosure. The key panel 11 shown in fig. 3 and the key panel 11 shown in fig. 2 are opposite plate surfaces of the key panel 11. Fig. 3 schematically shows a plate surface of the key panel 11 facing the mechanical switch 31.

As shown in fig. 1 and 3, the flexible key 2 further includes an isolation pillar 23, a first end of the isolation pillar 23 is connected to the connecting portion 212, and a second end of the isolation pillar 23 is connected to the circuit board 30.

Only after the flexible key 2 is pressed and the flexible key 2 is pushed to move for a certain distance, the mechanical switch 31 is triggered to operate, so that the accidental touch is prevented, and the reliability is improved.

Alternatively, as shown in fig. 1, the second end of the isolation column 23 has an insertion projection 231, the circuit board 30 is provided with an insertion slot 32, and the insertion projection 231 is inserted into the insertion slot 32.

In one implementation, as shown in fig. 1, the screw hole 232 of the isolation column 23 is disposed at the end of the insertion protrusion 231, and the insertion slot 32 on the circuit board 30 is a through hole penetrating through the circuit board 30. The screw 4 is threaded into the screw hole 232 of the insertion protrusion 231 after passing through the through hole, so as to fix the spacer 23 to the circuit board 30.
