The invention relates to the technical field of vehicle-mounted heat pump air conditioners, and particularly discloses a vehicle-mounted heat pump air conditioner based on a carbon dioxide refrigerant, which comprises a base, the base is arranged in a square frame shape, and a buffer device is matched with a buffer mechanism, so that when a vehicle is bumped and vibrated during running, the buffer mechanism can buffer the carbon dioxide refrigerant. When the heat pump air conditioner is in use, the mounting seat in the base shakes to drive the main body of the heat pump air conditioner to shake, at the moment, the second buffer springs and the second dampers on the connecting strips are pulled, the comprehensive damping and buffering effect is achieved, and the second buffer springs are borne by the inner side slopes of the middle base plate and the side base plates, so that elastic force in all directions is concentrated on the main body; a first buffer spring in the buffer mechanism is matched with a first damper to assist in enhancing the buffer performance, a first hinge ball and a second hinge ball are linked to enable buffer stress to act on the main body, the buffer function in any direction can be achieved, the comprehensive buffer performance is improved through the overall design, and the service life of the heat pump air conditioner main body is prolonged; and the stable running of the vehicle during running is ensured.

    本发明涉及车载热泵空调技术领域,具体公开了一种基于二氧化碳制冷剂的车载热泵空调,包括基座,所述基座呈口字型方框状设置,采用缓冲装置和缓冲机构相配合,使得车辆行驶中遇颠簸振动时,基座内安装座晃动带动热泵空调主体晃动,此时连接条上的第二缓冲弹簧及第二阻尼器被拉扯,发挥综合阻尼缓冲效果,中基板和侧基板内侧斜面承接第二缓冲弹簧,使各方向弹力集中于主体,缓冲机构中的第一缓冲弹簧配合第一阻尼器辅助增强缓冲性能,第一铰接球和第二铰接球联动使缓冲应力作用于主体,能够具有任意方向缓冲功能,整体设计提高了综合缓冲性能,延长了热泵空调主体使用寿命,确保其在车辆行驶中稳定运行。
