Description

Warm air core assembly structure of automobile air conditioner Technical Field The utility model relates to the technical field of installation of warm air cores of automobile air conditioners, in particular to an assembly structure of a warm air core of an automobile air conditioner. Background A warm air core in an automotive air conditioning system is an important component for achieving air heating and conditioning, and is typically assembled in an air conditioning distribution box housing. In the prior art, the warm air core is usually installed by adopting a side insertion mode, namely, the warm air core is installed from the side surface of the distribution box shell along the Y direction, and the fixing and sealing are realized through the sealing structure and the pressing structure. The structure has certain universality and is widely applied to vehicle models with wide space. For example, chinese patent CN202322397971.1 discloses a mounting structure for a warm air core of an automotive air conditioner, which comprises a distribution box shell and a warm air core, wherein the warm air core is mounted through the side of the distribution box, a mounting groove is formed in the distribution box shell, the warm air core is embedded into the mounting groove, sealing foam is arranged at the bottom, a pressing plate fixed by a screw is arranged above the sealing foam, and a limit rib is arranged on the pressing plate for limiting the position of the warm air core. The scheme has simple structure and is suitable for conventional space layout, but has certain limitation in practical application. First, such side mounting structures are difficult to implement in the case of limited vehicle construction space, particularly when the instrument panel, wiring harness, or other components are near the side of the distribution box, the warm air core cannot be inserted smoothly, affecting the mounting efficiency and feasibility. Secondly, because the warm air core is inserted from the side, whether the core is inserted to the bottom is difficult to observe in the installation process, and particularly when the sealing foam has compression deformation, whether the core is completely attached to a positioning area is difficult to confirm, and the problems of incomplete sealing, unstable assembly and the like are easily caused. In addition, the existing structure relies on an additional pressing plate piece to limit and fix, so that the number of parts is increased, and the assembly process and the manufacturing cost are improved. Therefore, the existing side-mounting structure of the warm air core still has room for improvement in terms of assembly flexibility, operation visibility and part optimization, and a novel warm air core assembly structure which can be simply assembled under the condition of limited space and has good sealing and positioning effects is needed. Disclosure of utility model The utility model aims to overcome the existing defects, and provides an assembly structure of a warm air core of an automobile air conditioner, which adopts a mode of installing the warm air core from the lower part of a distribution box to replace the traditional lateral insertion mode, is suitable for a narrow space limited by an instrument board or a side wall structure, effectively expands the installation application range, improves the flexibility of the whole automobile arrangement, and can effectively solve the problems in the background art. The utility model provides a warm air core assembly structure of an automobile air conditioner, which comprises a warm air core, a lower shell and a distribution box, wherein the traditional distribution box shell is divided into two parts of the distribution box and the lower shell, the lower shell and the distribution box are arranged into an open structure for installing the warm air core, the lower shell and the distribution box are fixed through screws, a cavity for fixing the warm air core is formed between the lower shell and the distribution box, a mounting groove is formed in one side surface of the distribution box, a fixing groove corresponding to the mounting groove is formed in the lower shell, a core limiting structure is formed by the mounting groove and the fixing groove, the warm air core is assembled from the lower side of the distribution box, and after the warm air core is confirmed to be installed in place, the lower shell and the distribution box are buckled, so that the warm air core is fixed. Because the lower part of the distribution box is of an open structure, the position of the warm air core body can be easily seen in the installation process of the warm air core body, whether the warm air core body is inserted into the bottom and whether the sealing sponge is pressed can be clearly confirmed through a bottom inserting mode, and the confirmation process is difficult to realize through a traditional side inserting structure.
