Description

Technical Field

[0001] This utility model belongs to the field of loader technology, specifically relating to a cab air conditioner cover. Background Technology

[0002] Loaders, as an important component of construction machinery, are widely used in construction sites such as building construction, mining, port terminals, and highway construction. They are characterized by high operating efficiency, good maneuverability, strong adaptability, and ease of operation. Furthermore, with the continuous development of construction machinery, the market has placed higher demands on the comfort of loader cabs, and air conditioning systems have become standard equipment. At the same time, the ease of assembly, high reliability, and timely and convenient maintenance of air conditioning systems and related components have become increasingly important.

[0003] At present, there are three main types of air conditioning evaporator installation locations in the loader field: (1) Evaporator is installed inside the cab, using the cab interior system or the entire cab as a protective cover; (2) Evaporator is installed on the top of the rear side of the cab and protected by an external protective cover; (3) Evaporator is distributed on the right side of the cab and protected by a special air conditioning cover.

[0004] When using dedicated air conditioner covers for protective installation, to ensure the maintainability of the cab's air conditioning system, existing dedicated air conditioner covers mostly adopt an external structure for installation. Furthermore, the manufacturing processes and materials for these covers are mostly sheet metal stamping and fiberglass molding. However, both of these processes exhibit certain drawbacks in practical applications: 1. Sheet metal stamping external air conditioner covers typically connect to the cab body using bushings or hinges. This connection method often leads to welding deformation and insufficient rigidity of the air conditioner cover after welding, resulting in low assembly efficiency, difficulty in closing the cover, and consequently affecting the sealing performance. Moreover, the significant weight of sheet metal stamping air conditioner covers increases the difficulty of installation. 2. Fiberglass air conditioner covers, due to the inherent strength and hardness of the material, are prone to cracking during installation and disassembly if torque is not properly controlled. Additionally, the vibrations generated by the loader during prolonged operation due to the working environment and the physical properties of fiberglass can easily cause the air conditioner cover to tear, adversely affecting the loader's normal operation. Utility Model Content

[0005] The purpose of this utility model is to address the shortcomings of existing air conditioner covers, such as high installation difficulty, poor installation quality, and short service life, by proposing and designing a new type of cab air conditioner cover that can reduce the overall weight of the air conditioner cover, reduce the assembly difficulty, improve assembly efficiency, and increase the overall service life of the air conditioner cover.

[0006] To achieve the above objectives, the technical solution provided by this utility model is as follows: a cab air conditioner cover, comprising an injection-molded cover body, a cab connection portion provided on the rear side of the injection-molded cover body, a maintenance window provided on the side of the injection-molded cover body, a maintenance door hinged to the maintenance window, and a latch provided between the maintenance door and the injection-molded cover body. Since the cover body in this utility model is manufactured using an integral injection molding process, it not only has the characteristics of being lightweight and having a long service life, but also reduces the assembly difficulty of the air conditioner cover, improves assembly efficiency, and minimizes welding errors. Furthermore, since this utility model designs maintenance windows and doors at frequently maintained locations and uses hinges and latches for fixation, it avoids problems with the cover lock opening and closing, improves maintenance convenience, reduces unnecessary maintenance time, and increases the overall working time of the loader.

[0007] Furthermore, a sealing strip is provided on the edge of the maintenance window and / or maintenance door, and the mating area between the maintenance window and the maintenance door is sealed by the sealing strip.

[0008] Furthermore, a drainage channel is recessed along the inner edge of the maintenance window, and a drain outlet is located at the bottom of the maintenance door. When the maintenance door is closed, the drainage channel is located inside the door, and the drain outlet connects the drainage channel to the outside. If liquid enters the injection-molded housing through the gap between the maintenance window and the maintenance door, it will be collected through the drainage channel to prevent contamination of the air conditioner evaporator inside the injection-molded housing; simultaneously, the collected liquid can be discharged from the injection-molded housing through the drain outlet.

[0009] Furthermore, the maintenance window includes an upper window located on the upper side of the injection-molded cover, and the maintenance door includes an upper side door hinged to the upper window. A latch is provided between the upper side door and the injection-molded cover, and the upper side door is locked using this latch. This allows the present invention to facilitate maintenance and upkeep of the frequently maintained area on the upper part of the air conditioner evaporator inside the injection-molded cover by the workers through the upper side door.

[0010] Furthermore, the maintenance window includes a right window located on the right side of the injection-molded cover, and the maintenance door includes a right door hinged to the right window. A latch is provided between the right door and the injection-molded cover, and the right door is locked using this latch. This allows the present invention to facilitate maintenance and upkeep of the frequently maintained area on the right side of the air conditioner evaporator inside the injection-molded cover by the workers through the right door.

[0011] Furthermore, a second sealing strip is provided on the side of the cab connection that is in contact with the cab, and the sealing performance of the connection between the injection molded cover and the cab is enhanced by the second sealing strip.

[0012] Furthermore, the second sealing strip is a sponge strip, which can be directly adhered to the cab connection using adhesives such as glue.

[0013] Furthermore, reinforcing ribs are provided on the inner side of the injection-molded cover, and these reinforcing ribs ensure the overall strength of the injection-molded cover.

[0014] Furthermore, the latch is a spring-loaded latch, so that when it is in the closed state, it can tightly lock the corresponding maintenance door and maintenance window together under the action of the spring.

[0015] Furthermore, the hook of the spring-loaded latch has a bending depth of 6-9mm, thereby preventing the spring-loaded latch from opening due to bumps and jolting during the complex working conditions of the loader.

[0016] As can be seen from the above technical solutions, this utility model has the following advantages:

[0017] 1. The cover and maintenance door of the cab air conditioner cover provided by this utility model are both made of injection molding in one piece, and can be directly assembled with the cab body using bolts and washers. Therefore, it has the characteristics of simple assembly and installation. Compared with the hinge bushing installation method, it avoids the existence of welding errors to the greatest extent and improves assembly efficiency. At the same time, the use of mold injection molding process can also ensure manufacturing precision to the greatest extent and ensure the interchangeability of different batches of the same product.

[0018] 2. Since the cab air conditioner cover provided by this utility model is manufactured using injection molding, when it uses conventional injection molding materials such as ABS, it not only reduces the weight of the air conditioner cover itself and improves assembly and personnel usage efficiency, but also allows the color of the air conditioner cover to be changed directly by adjusting the material itself, eliminating the need for painting, thereby further reducing production costs, avoiding the disadvantage of poor paint adhesion of plastic materials, and preventing paint peeling caused by prolonged exposure to sunlight; at the same time, this technology has good adaptability and can be promoted in similar products, with broad applicability and easy to achieve significant results.

[0019] 3. Because the cab air conditioner cover provided by this utility model is designed with maintenance windows and maintenance doors in frequently maintained locations, and is fixed by the cooperation of hinges and buckles, it can avoid the problem of the cover lock opening and closing not being smooth, while improving the convenience of maintenance, reducing unnecessary maintenance time, and increasing the working time of the loader.

[0020] 4. Because the cab air conditioner cover provided by this utility model is designed with water guide grooves, sealing strips and other structures, it can improve the overall sealing performance of the air conditioner cover and prevent water from flowing into the interior of the cover.

[0021] 5. Because the buckle in this utility model adopts a spring-type buckle structure and its hook is designed with an extended length, it not only ensures that the buckle has a certain force when closed, but also prevents the buckle from opening actively under the bumps of complex working conditions through the extended hook.

[0036] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0037] like Figures 1 to 12 As shown, this utility model provides a cab air conditioner cover, which includes an injection-molded cover body 1 integrally injection molded using an injection molding process. The rear side of the injection-molded cover body 1 is configured as a cab connection part. The cab connection part preferably adopts a flange structure, and a ring of mounting holes runs through the surface of the cab connection part. This allows it to be directly installed on the cab side door via gaskets and bolts passing through the mounting holes, eliminating the need for welding and minimizing welding errors, thereby improving overall assembly efficiency. Furthermore, as a preferred embodiment, this utility model can also provide a thickened boss at the location of the mounting holes on the inner side of the cab connection part to prevent cracking of the cover body due to improper torque control during assembly; and reinforcing ribs can be provided on the inner side of the cab connection part to improve overall strength; simultaneously, a bonding space can be reserved on the inner side of the cab connection part, and conventional sealing strips such as sponge strips can be adhered within this bonding space to ensure a tight seal when the injection-molded cover body 1 is connected to the cab body.

[0038] A maintenance window is provided on the front side of the injection-molded cover 1. This maintenance window corresponds to the frequently maintained position of the air conditioner evaporator. A maintenance door is hinged to the maintenance window via hinges 4 and other connecting components. The maintenance door is locked to the injection-molded cover 1 via latches 5, facilitating maintenance and repair of the air conditioner evaporator by personnel. Specifically, in this embodiment, as... Figure 2 , Figure 4As shown, the maintenance window in this utility model includes an upper window on the upper side of the injection-molded cover 1 and a right window on the right side of the injection-molded cover 1. The maintenance door in this utility model includes an upper door 2 hinged to the upper window and a right door 3 hinged to the right window. The upper door 2 is installed on the upper side of the injection-molded cover 1 via a latch 5, and the right door 3 is installed on the right side of the injection-molded cover 1 via a latch 5. The hinge 4 is preferably made of anodized aluminum alloy to prevent rusting after long-term use under complex working conditions. The latch 5 is preferably made of stainless steel, and the type of latch 5 is preferably a spring-loaded latch with a spring 502, providing a certain force when closed. The hook 501 of the latch 5 can be extended, meaning the bending depth of the hook 501 can be set to 6-9mm to prevent the latch 5 from opening actively during bumpy conditions.

[0039] Moreover, as a preferred embodiment, this utility model not only has reinforcing ribs designed on the inner side of the upper door 2 and the inner side of the right door 3, but also has thickened the positions on the upper door 2, the right door 3 and the injection molded cover 1 where the hinges 4 and buckles 5 are installed, in order to ensure the overall strength and prevent cracking when the buckles 5 and hinges 4 are riveted and installed.

[0040] In addition, the present invention also provides a sealing strip at the upper side and the edge of the right door 3 of the injection molded cover 1, and seals the joint between the upper side and the upper window, and the joint between the right door 3 and the right window, thereby improving the overall sealing performance of the cover and preventing external debris from entering the injection molded cover 1.

[0041] Meanwhile, to prevent water ingress after the sealing strip fails, this invention also features a drainage groove 101 recessed at the edge of the upper window and a water outlet 201 at the bottom of the upper door 2. When the upper door 2 is closed, the drainage groove 101 is located below the upper door 2, and the water outlet 201 connects to the drainage groove 101 to communicate with the outside. If liquid enters the injection-molded housing 1 through the gap between the upper window and the upper door 2, it is collected through the drainage groove 101, preventing contamination of the air conditioner evaporator inside the injection-molded housing 1. Simultaneously, the collected liquid can be discharged from the injection-molded housing 1 through the water outlet 201. A flow guide groove 102 is recessed to the left and inward from the edge of the right window. A water outlet 301 is located at the bottom of the right door 3. When the right door 3 is closed, the flow guide groove 102 is located to the left of the right door 3, and the water outlet 301 connects to the flow guide groove 102 and communicates with the outside. If liquid enters the injection-molded housing 1 through the gap between the right window and the right door 3, it will be collected through the flow guide groove 102, preventing contamination of the air conditioner evaporator inside the injection-molded housing 1. Simultaneously, the liquid can be guided through the flow guide groove 102 to the water outlet 301, and the collected liquid will be discharged from the injection-molded housing 1 through the water outlet 301, preventing water ingress into the air conditioner evaporator inside the injection-molded housing 1.

[0042] Based on this, on the one hand, since the core part of the air conditioner cover in this utility model is made of ABS material and manufactured using injection molding, it not only reduces the weight of the injection-molded cover 1 itself, improving assembly and worker efficiency, but also minimizes manufacturing errors by using a mold-in-one molding process, ensuring interchangeability between different batches of the same product, which is beneficial to improving market after-sales efficiency. Simultaneously, it can be pre-mixed in color, eliminating the need for painting, thereby reducing production costs and effectively solving the problem of poor paint adhesion on plastic materials, preventing paint peeling after long-term exposure to sunlight. Furthermore, the use of reinforcing ribs inside the injection-molded cover 1 increases strength and improves its stability, effectively reducing cracking. On the other hand, it not only improves maintenance convenience by designing maintenance windows and doors at frequently maintained locations, reducing unnecessary maintenance time and increasing the overall working time of the loader; it also improves the overall sealing performance of the air conditioner cover through sealing strip and guide channel structures, and avoids problems with the cover lock opening and closing due to manufacturing errors by using a latch switch structure, while simultaneously improving maintenance efficiency.
