Abstract
Description
Technical Field
[0001] The utility model relates to an electric control box component of an air conditioner. Background Art
[0002] Air conditioner outdoor units typically have an electrical control box located on the top right or left side of the housing. This access allows for easy access to the electronic control circuit board by opening the top panel. Traditional electrical control boxes still use screws to secure the cover, which is designed to protect against dust and water. Using screws to secure the cover reduces installation and removal efficiency, and can easily cause screws to fall into the housing during installation and removal.
[0003] Therefore, it is necessary to make further improvements. Utility Model Content
[0004] In order to solve the above problem, the present invention provides an air conditioner electric control box assembly, which solves the problem that the above screws are prone to falling into the interior of the casing.
[0005] The utility model proposes an air-conditioning electric control box assembly, which includes a base box and a cover body. The base box has an installation space with a lower opening. The installation space is used to store and install a circuit board. The circuit board is fixed to the base box by screws. An outwardly protruding connecting step is provided on the left side wall of the opening. An elastic buckle is provided on the right side wall of the opening. The cover body is covered on the opening, and the cover body has a connecting hole connected to the connecting step and a bayonet connected to the elastic buckle.
[0006] In one or more embodiments, convex steps are provided on the inner wall of the installation space, and the convex steps are horizontally distributed around the inner wall of the installation space. Screw holes are provided at the corners of the convex steps in the installation space.
[0007] In one or more embodiments, the outer side wall of the bottom box is provided with a supporting step for abutting against the cover body, and when the cover body is covered on the bottom box, the supporting step abuts against the bottom box.
[0008] In one or more embodiments, a radiator is provided on the bottom box, the bottom of the radiator is located inside the installation space, and an escape opening is opened on the bottom box for the heat sink of the radiator to extend out.
[0009] In one or more embodiments, the bottom box and the cover are both integrally formed by injection molding.
[0010] In one or more embodiments, a plurality of open wire clamping parts are provided on the bottom box, a wire clamping space is formed in the wire clamping parts, and the wire clamping parts have elastic wire passing openings.
[0011] The beneficial effects of the present invention are as follows: the bottom box and the cover body are installed together by adopting a combined connection structure of docking and buckling. When disassembling, it is only necessary to disassemble and unhook one end of the elastic buckle, and then move the cover body so that the connecting hole is out of the connecting step to complete the disassembly of the cover body. It has the advantages of easy installation and disassembly, and no screws are used, so the installation and disassembly efficiency is extremely high. BRIEF DESCRIPTION OF THE DRAWINGS

[0016] In order to deepen the understanding of the present invention, the present invention will be further described in detail below with reference to embodiments and drawings. The embodiments are only used to explain the present invention and do not constitute a limitation on the scope of protection of the present invention.
[0017] See attached Figure 1-4 The utility model provides an air-conditioning electric control box assembly, which includes a base box 1 and a cover body 2. The base box has an installation space with an opening at the bottom, and the installation space is used to store and install a circuit board. The circuit board is fixed to the base box 1 by screws. An outward-convex connecting step 3 is provided on the left wall of the opening, and an elastic hook 4 is provided on the right wall of the opening. The cover body 2 is covered on the opening, and the cover body has a connecting hole 5 connected to the connecting step 3 and a bayonet 6 connected to the elastic hook 4. When installing, connect the connecting hole on the cover body with the connecting step, and then align the side of the cover body at the bayonet and press down so that the bayonet is engaged with the elastic hook; when disassembling, pull out the elastic hook, lift the cover body, and then move the cover body horizontally to separate the connecting hole from the connecting step.
[0018] A convex step 7 is provided on the inner wall of the installation space, and the convex steps are horizontally distributed around the inner wall of the installation space. The convex steps are provided with screw holes 8 at the corners of the installation space. The convex steps support and position the edges of the circuit board. The reserved holes on the circuit board are connected by screws and screwed into the screw holes to complete the installation process of the circuit board.
[0019] The outer side wall of the bottom box is provided with a supporting step 9 for abutting against the cover body 2. When the cover body is placed on the bottom box, the supporting step abuts against the bottom box and the supporting step abuts against the cover body, which can limit the cover body and protect the edge position of the cover body.
[0020] A radiator 10 is provided on the base box, the bottom of the radiator is located inside the installation space, and a relief opening is provided on the base box for the radiator's fins to extend out. The radiator contacts the heating elements on the circuit board to conduct away the heat, thereby achieving a physical cooling effect on the circuit board.
[0021] The base box 1 and the cover 2 are both integrally formed by injection molding. The injection-molded base box and cover are lightweight and inexpensive.
[0022] The base box 1 is provided with a plurality of open wire clamping parts 11, a wire clamping space is formed in the wire clamping part, and the wire clamping part has an elastic wire passing opening, through which the wire harness external to the circuit board can be fixed in the wire clamping space to prevent the wire harness from being pulled and released at will.
[0023] The above description is only a preferred embodiment of the present invention. The protection scope of the present invention is not limited to the above embodiment. Any equivalent modifications or changes made by ordinary technicians in this field based on the content disclosed in the present invention should be included in the protection scope recorded in the claims.
