  • Publication number: 20250171066
    Abstract: A collapsible wagon is provided. The collapsible wagon includes: a support assembly including a first support and a second support that are spaced apart in a first direction; and a chassis assembly arranged between the first support and the second support and including a first chassis hinged to the first support and a second chassis hinged to the second support. The first chassis is configured to comprise a first parallel-bars structure vertically arranged, and the second chassis is configured to comprise a second parallel-bars structure vertically arranged. The first parallel-bars structure and the second parallel-bars structure are hinged to a groove connector, and are configured to respectively drive the first chassis and the second chassis to move synchronously in response to movement of the groove connector in a vertical direction. The present disclosure adopts a chassis assembly having parallel-bars structures, which improves support strength.

  • Publication number: 20250085007
    Abstract: The present disclosure discloses a method for determining parameters of an HVAC system, a computer-readable storage medium, and an electronic device. The method includes: determining a region area of a target indoor region; obtaining an object number and an activity intensity of at least one object in the target indoor region by a UWB radar sensor; determining an overall demand of the HVAC system for outdoor ventilation based on the region area and the object number and the activity intensity of the at least one object; and determining operational parameters of the HVAC system based on the overall demand. The present disclosure solves the technical problem of inaccuracy when the HVAC system obtains indoor control requirements of a building in related art.

  • Patent number: 11014584
    Abstract: A coupler telescopic apparatus comprises a housing and a drawbar capable of extending and retracting along the housing, the housing is sleeved outside the drawbar, a limiting block is fixed arranged on an outer side face of the drawbar, a locking ring capable of coming into contact with the limiting block is sleeved inside the housing, and the locking ring is coaxial with the housing and rotatably connected to the housing; a through groove is axially formed on an inner surface of the locking ring, and the through groove correspond to the limiting block in shape, so that the limiting block passes through the through groove when the through groove is aligned with the limiting block, and then an extension of the drawbar is locked by rotating the locking ring to block the limiting block after the extension of the drawbar is completed. The present application can reduce space occupation and has simple structure.
