A self-adaptive cabin air conditioning system, a control method therefor, and a mobile vehicle having the system. The mobile vehicle (3, 3&#39;, and 3&#34;) having the self-adaptive cabin air conditioning system comprises: a mobile vehicle body (31), accommodating at least one mobile vehicle cabin (33, 33&#39;, and 33&#34;); and at least one self-adaptive cabin air conditioning system (1, 1&#39;, and 1&#34;). The self-adaptive cabin air conditioning system further comprises: a temperature collecting device (11, 11&#39;, and 11&#34;); a temperature control device (13, 13&#39;, and 13&#34;); and a microprocessor (15 and 15&#34;) for receiving a temperature signal.
A: An automatic displacement device for a movable vehicle. The movable vehicle is used for carrying at least one weight. The movable vehicle comprises a body. The automatic displacement device comprises: at least one weight fixer, used for carrying the weight; at least one actuator, disposed on the body, and mechanically connected to the weight fixer and used for moving the weight fixer; at least one stabilization controller, in signal connection with the actuator, and comprising at least one sensing assembly used for sensing the inclination state of the body and sending at least one inclination state signal; and at least one control assembly, used for computing the inclination state and driving the actuator to move the weight fixer so as to perform compensation according to the inclination state signal.
B: A freely movable apparatus (3) and an ultrasonic apparatus. The freely movable apparatus (3) has a first moving element (33) and a second moving element (34). The first moving element (33) and the second moving element (34) are disposed to be rotatable on a support element (31). When a user applies a force on a connecting base (39) or connecting arms (35, 36), the positions of the first moving element (33) and the second moving element (34) on the support element (31) can be changed, such that the first moving element (33) and the second moving element (34) can rotate, according to the applied force, by different angles or move away from each other or move towards each other on the support element (31) The angles between the connecting arms (35, 36) and the connecting base (39) and between the connecting arms (35, 36) and the moving elements (33, 34) can vary according to the applied force, such that the connecting base (39) can move and rotate to multiple positions in a plane. The structure can realize free multidirectional movement in a horizontal plane and is simple, such that the compactness and linkage flexibility of an apparatus are improved.
C: Disclosed is an intelligent in-vehicle air conditioning system. The intelligent in-vehicle air conditioning system comprises a vehicle body (1) and an in-vehicle air conditioner (2). An interior of the vehicle body (1) is provided with multiple air outlets (10) in communication with air outlets of the in-vehicle air conditioner (2) and arranged symmetrically on two sides of a top portion of the vehicle body (1). Bladeless fans (11) are provided on two sides of the interior of the vehicle body under the air outlets (10). The system further comprises a solar cell panel (12) on an upper end of the vehicle body (1), a control module (3) used to control operation of the in-vehicle air conditioner (2) and the bladeless fans (11), a flow speed detection module (4) used to detect an airflow speed in the vehicle body (1), a temperature detection module (5), a micro-processor (6) used to process data from the flow speed detection module (4) and the temperature detection module (5) and send a result to the control module (3), and a power supply switching module (7). The system rapidly distributes cool air by means of the bladeless fans (11), and increases the airflow speed in the vehicle to bring superior comfort. In addition, after the flow speed detection module (4) and the temperature detection module (5) perform detection, the micro-processor (6) processes the detected information and transmit a result to the control module (3) to perform intelligent adjustment on the in-vehicle air conditioner (2) and the bladeless fans (11), thus realizing a highly intelligent system.
D: A floating apparatus (3) and an ultrasonic device. A first moving member (33) and a second moving member (34) are configured to reciprocate in an arc-shaped or circular trajectory on a support member (31). Meanwhile, both ends of lift arms (35, 36) are hingedly connected to moving members (33, 34) and a connection base (39), respectively. When a user applies force to the connection base (39) or the lift arms (35, 36), the positions of the first moving member (33) and the second moving member (34) on the support member (31) can be changed, so that the first moving member (33) and the second moving member (34) are distant from and get close to each other on the support member (31) according to the stress in the arc-shaped or circular trajectory. Meanwhile, the angle between the lift arms (35, 36) and the connection base (39), and the moving members (33, 34) can also be changed according to the stress, so that multi-position movement and rotation is achieved for the connection base (39) in a plane. Meanwhile, the lift arms (35, 36) have the lift function, so that the spatial floating in horizontal and vertical directions can be achieved by combining other components. The structure is more simplified while achieving multi-azimuth floating in horizontal and vertical directions, and improves the compactness of the apparatus, and the linkage flexibility is better.
