Description

Technical Field

[0001] The present application belongs to the technical field of evaporator covers, and in particular relates to an evaporator cover for an automobile air conditioner that is easy to install. Background Art

[0002] The car air conditioning evaporator cover refers to the component used to cover and protect the car air conditioning evaporator. The air conditioning evaporator is one of the main components in the air conditioning system. It is located inside the vehicle and is responsible for evaporating the refrigerant and absorbing the heat of the air inside the car, thereby achieving a cooling effect. The evaporator cover is usually located behind the dashboard of the vehicle and is used to cover and protect the evaporator from dust, dirt and other debris. At the same time, the evaporator cover also reduces noise, prevents water vapor condensation and improves the efficiency of the air conditioning system.

[0003] The evaporator cover is usually composed of two upper and lower shells. The upper and lower shells are responsible for fixing the internal components of the evaporator, and can also play the role of isolation, protection and sealing. The upper and lower shells are usually fixed together by multiple screws to form a complete evaporator structure. The design and manufacture of the upper and lower shells are intended to ensure that the evaporator can effectively evaporate the refrigerant and exchange heat with the air, thereby achieving cooling of the air in the car. In addition, the upper and lower shells can also reduce noise and vibration transmission, and improve the efficiency and comfort of the air conditioning system;

[0004] However, the existing upper and lower shells are fixed together by multiple screws, so that personnel need additional tools and tighten the screws one by one when disassembling or assembling the upper and lower shells. Such operation is not only labor-intensive, but also easily causes damage to other components, increasing the complexity and time cost of disassembly or installation. Therefore, an easy-to-install automobile air-conditioning evaporator cover is provided. Utility Model Content

[0007] In a preferred embodiment, the inner side wall of the arc-shaped sealing frame is symmetrically provided with a plurality of positioning grooves, and the side of the upper end cover shell is symmetrically fixed with a plurality of positioning blocks corresponding to the positioning grooves, and the positioning blocks are inserted into the interior of the positioning grooves.

[0008] In a preferred embodiment, an evaporator body is fixedly installed inside the lower end cover shell.

[0009] In a preferred embodiment, a connecting rod is fixedly mounted on one end of the connecting column extending to the outside of the mounting protrusion.

[0010] In a preferred embodiment, air guide covers are fixedly mounted on the front sides of the lower end cover shell and the upper end cover shell respectively.

[0011] In a preferred embodiment, the top and bottom ends of the front-facing surface of the fixed inclined plate are both arc-shaped.

[0024] refer to Figure 1 , Figure 4 and Figure 5 A plurality of positioning grooves 11 are symmetrically provided on the inner side wall of the arc-shaped sealing frame 2, and a plurality of positioning plugs 12 corresponding to the positioning grooves 11 are symmetrically fixedly installed on the sides of the upper end cover shell 3, and the positioning plugs 12 are inserted into the interior of the positioning grooves 11; by inserting the positioning plugs 12 into the interior of the positioning grooves 11, it is convenient to position and install the upper end cover shell 3, so that it will not be offset during installation, thereby improving the installation efficiency.

[0025] refer to Figure 1 , Figure 2 and Figure 3 A plurality of mounting protrusions 4 are symmetrically installed on the left and right sides of the arc-shaped sealing frame 2, and a movable plate 5 is movably connected inside the plurality of mounting protrusions 4; a total of four mounting protrusions 4 are installed, with two mounting protrusions in each group, and the two groups of mounting protrusions 4 are respectively installed on the left and right sides of the arc-shaped sealing frame 2. The setting of the mounting protrusions 4 facilitates the internal movement and adjustment of the movable plate 5.

[0026] refer to Figure 1 , Figure 2 and Figure 3A spring 6 is fixedly installed on one side of the movable plate 5, and one end of the spring 6 away from the movable plate 5 is fixed to the inner side wall of the mounting protrusion 4. A connecting column 7 is fixedly installed on one side of the movable plate 5, and one end of the connecting column 7 passes through the middle of the spring 6 and extends to the outside of the mounting protrusion 4. A connecting rod 14 is fixedly installed on the end of the connecting column 7 extending to the outside of the mounting protrusion 4; through the setting of the connecting rod 14, it is convenient to drive the connecting column 7 and the movable plate 5 to move toward the inside of the mounting protrusion 4, and through the setting of the spring 6, it is convenient to drive the movable plate 5 to reset.

[0027] refer to Figure 1 , Figure 2 and Figure 3 A push rod 8 is fixedly installed on the side of the moving plate 5 away from the spring 6, and a fixed inclined plate 9 is fixedly installed on one end of the push rod 8. The top and bottom of the fixed inclined plate 9 facing the front are both arc-shaped, and a rectangular groove 10 corresponding to the fixed inclined plate 9 is opened on the side of the upper end cover shell 3, and the fixed inclined plate 9 is inserted into the inside of the rectangular groove 10; by setting the fixed inclined plate 9 to be inserted into the inside of the rectangular groove 10, it is convenient to fix the upper end cover shell 3 that is positioned and installed, thereby improving the convenience of installation.

[0028] The implementation principle of an embodiment of an automobile air-conditioning evaporator cover that is easy to install in the present application is as follows: the user first installs the evaporator body 13 inside the lower end cover shell 1. When the personnel need to install the upper end cover shell 3, first pick up the upper end cover shell 3 and make the positioning plug 12 correspond to the positioning groove 11. At this time, the personnel press the upper end cover shell 3 downward to make the positioning plug 12 plug into the inside of the positioning groove 11, which is convenient for positioning and installing the upper end cover shell 3. When the upper end cover shell 3 continues to move downward and makes the rectangular groove 10 correspond to the fixed inclined plate 9, the fixed inclined plate 9 is plugged into the inside of the rectangular groove 10 under the action of the spring 6 releasing the rebound force. This makes it easy to install and fix the upper end cover shell 3, so that the lower end cover shell 1 and the upper end cover shell 3 form an integral protective shell to isolate, protect and seal the evaporator body 13;

[0029] When it is necessary to disassemble the upper end cover shell 3, the user first pulls the connecting rod 14 outwards, and the connecting rod 14 drives the movable plate 5 and the fixed inclined plate 9 to move toward the inside of the mounting protrusion 4, so that it is convenient for the fixed inclined plate 9 to release the internal restriction of the upper end cover shell 3, so that it is convenient for personnel to disassemble the upper end cover shell 3 from the top of the lower end cover shell 1. The device has a simple structure and is easy to operate. Since the top and bottom ends of the fixed inclined plate 9 are both arc-shaped, when the bottom of the positioned upper end cover shell 3 contacts the fixed inclined plate 9, the fixed inclined plate 9 will enter the inside of the mounting protrusion 4 under the left and right of the extrusion force. When the fixed inclined plate 9 corresponds to the rectangular groove 10, the fixed inclined plate 9 will enter the inside of the rectangular groove 10 driven by the spring 6, so it is convenient to install the upper end cover shell 3. The overall installation and disassembly of the upper end cover shell 3 is relatively convenient, which is convenient for personnel to inspect and maintain the evaporator body 13 in the protective shell, thereby improving work efficiency.
