[0002] Most parts of an air conditioner's outdoor unit are made of metal, and the entire unit typically weighs over 25 kg. The chassis, as the main load-bearing component, is made of sheet metal. During handling and transportation, the weight of the unit can easily cause deformation of the bottom of the casing and the chassis, leading to customer complaints. During after-sales installation, the chassis needs to be properly secured to the tripod. If the chassis is deformed, it won't fit snugly on the tripod, resulting in excessive vibration and noise from the compressor during operation. Furthermore, if the mounting holes on the chassis and tripod are deformed, they won't align perfectly, making it difficult for the installer to securely fasten the outdoor unit chassis.

[0003] To address the issue of chassis deformation, protective devices such as foam components are added to the top and bottom of the outdoor unit during the encapsulation process. However, existing protective devices only provide protection for the outdoor unit, resulting in limited functionality and low space utilization. Utility Model Content

[0028] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The preferred embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0029] Reference Figures 1 to 5 The diagram illustrates an embodiment of the chassis protection device and air conditioner of this utility model. The chassis protection device includes a main body 1 for protecting the chassis. The main body 1 is provided with two clearance grooves 10 for limiting the chassis and a mounting groove 20. The two clearance grooves 10 are respectively located on both sides of the main body 1 and extend along the width direction of the main body 1. The mounting groove 20 is located on the side of the clearance groove 10 near the edge of the main body 1 and is used to install the insulation strip of the air conditioner.

[0030] Specifically, the chassis protection device is installed at the bottom of the outdoor unit of the air conditioner to protect the chassis of the outdoor unit and prevent deformation of the chassis after impact during handling or transportation. The chassis protection device includes a main body 1, which is used to protect the chassis, that is, the main body 1 covers the chassis to prevent the chassis from being bumped. The shape of the main body 1 is adapted to the shape of the chassis of the outdoor unit of the air conditioner, that is, the main body 1 is rectangular. Since the main body 1 is installed between the packaging box and the chassis, the length and width of the main body 1 are greater than the length and width of the chassis, and the length and width of the main body 1 are less than the length and width of the packaging box, so that the main body 1 can better protect the chassis. The structure of the main body 1 is based on the structural design of the chassis. The thickness of the main body 1 can be determined according to the weight protection requirements of the outdoor unit of the air conditioner to ensure that the entire outdoor unit of the air conditioner will not deform during handling and transportation after installation.

[0031] The upper surface of the main body 1 is fitted to the chassis, and the chassis is embedded in the main body 1 to connect the outdoor unit of the air conditioner to the main body 1. The main body 1 is provided with two clearance grooves 10 and a mounting groove 20. The clearance grooves 10 are used to embed and connect with the fixing block on the lower end surface of the chassis, thereby limiting the position of the chassis and preventing the chassis from separating from the main body 1, so as to facilitate the handling of the outdoor unit of the air conditioner and the main body 1. The two clearance grooves 10 are provided on both sides of the main body 1 to limit the sides of the chassis and improve the stability of the limit. They extend along the width direction of the main body 1, and the clearance grooves 10 are formed by a downward indentation from the upper end surface of the main body 1. The width of the clearance groove 10 is greater than the width of the fixing block on the lower end face of the chassis, and the length of the clearance groove 10 is greater than the length of the fixing block on the lower end face of the chassis. The clearance groove 10 engages with the fixing block, that is, when assembling the outdoor unit of the air conditioner and the chassis protection device, the fixing block on the lower end face of the chassis of the outdoor unit of the air conditioner engages with the clearance groove 10. The clearance groove 10 limits the chassis to the main body 1, thereby realizing the fixed connection between the chassis protection device and the outdoor unit of the air conditioner. At the same time, the depth of the clearance groove 10 is consistent with the height of the chassis, ensuring that the chassis is not suspended after assembly and can be effectively supported by the main body 1.

[0032] The main body 1 is also provided with a mounting groove 20, which is used to install the insulation strip of the air conditioner. The mounting groove 20 is located on one side of the main body 1 and is located on the side of the relief groove 10 near the edge of the main body 1, thereby avoiding the chassis so that the chassis can be connected to the relief groove 10. The mounting groove 20 is formed by the upper end of the main body 1 being recessed downwards. The size of the mounting groove 20 matches the size of the insulation strip so that the insulation strip in the packaging accessories can be installed in the mounting groove 20 before leaving the factory, so as to prevent the insulation strip from rolling away and being lost.

[0033] This application provides a chassis protection device installed under the chassis of the outdoor unit of the air conditioner. The main body 1 is connected to the chassis by engaging with the chassis through the clearance groove 10. The main body 1 protects the chassis and prevents the chassis from deforming under stress. Furthermore, an installation groove 20 is provided at the edge of the main body 1 for installing insulation tape, thereby improving the space utilization of the main body 1 and avoiding waste. The main body 1 has both protective and storage functions, making it versatile.

[0034] More specifically, the main body 1 uses EPS foam material, which takes advantage of the plasticity and economy of foam. The foam material is lightweight, has good cushioning performance, is moisture-resistant and high-temperature resistant, and will not affect the chassis even in harsh storage environments.

[0035] In one embodiment, referring to Figures 1 to 3 As shown, the mounting groove 20 is formed by a downward-facing indentation on the upper end of the main body 1, and the mounting groove 20 has an arc structure. Specifically, the mounting groove 20 is formed by a downward-facing indentation on the upper end of the main body 1 to facilitate the installation of the insulation strip. The insulation strip is fixed in the mounting groove 20 by embedding. Since the insulation strip is cylindrical, the mounting groove 20 is set as an arc structure, especially a semi-circular arc structure, so that the mounting groove 20 fits the shape of the insulation strip better and better embeds the insulation strip into the mounting groove 20. The outer surface of the insulation strip is tightly attached to the mounting groove 20, so that the insulation strip is more firmly fixed in the mounting groove 20, preventing the insulation strip from detaching from the mounting groove 20 and affecting the handling or transportation of the outdoor unit of the air conditioner.

[0036] In a specific embodiment, refer to Figures 1 to 3 As shown, there are two mounting slots 20, which are arranged side by side and spaced apart on the same side of the main body 1. Specifically, the main body 1 has two mounting slots 20, both located on the same side of the main body 1, and arranged side by side near the edge of the main body 1. The two mounting slots 20 are spaced apart, with one slot serving as a spare. That is, one mounting slot 20 is used to accommodate the insulation strip, while the other is kept as a backup. This improves the utilization rate of the main body 1 and avoids the situation where the main body 1 is unusable if one mounting slot 20 cracks. Furthermore, when installing the insulation strip into the mounting slot 20, workers can freely choose one of the mounting slots 20 to embed the insulation strip, improving installation efficiency.

[0037] In one embodiment, referring to Figures 1 to 3As shown, the main body 1 is further provided with a boss 30, which protrudes upward from the bottom wall of the relief groove 10. Specifically, the main body 1 is further provided with a boss 30, which is used to further fix the chassis; the boss 30 is located in the relief groove 10, and the boss 30 protrudes upward from the bottom wall of the relief groove 10. The boss 30 is used to cooperate with the hollow structure of the fixing block of the chassis for fixation, that is, the boss 30 corresponds to the hollow structure of the fixing block. When assembling the chassis and the main body 1, the boss 30 is embedded in the hollow structure of the fixing block, thereby further limiting the chassis and improving the stability of the chassis and the main body 1. At the same time, the boss 30 can better support the chassis.

[0038] More specifically, the main body 1 is provided with a plurality of protrusions 30, which are spaced apart on the relief groove 10 along the extending direction of the relief groove 10 to better fix the chassis.

[0039] In a specific embodiment, refer to Figures 1 to 3 As shown, the main body 1 also has a mounting hole 40, which is located on the upper surface of the main body 1 near its corner, for installing the drain connector of the air conditioner. Specifically, the main body 1 also has a mounting hole 40 for installing the drain connector of the air conditioner. The mounting hole 40 is formed by a downward recess on the upper surface of the main body 1 and is located near its corner. The diameter of the mounting hole 40 is the same as the diameter of the drain connector in the packaging accessories. Before the air conditioner leaves the factory, the drain connector is inserted into the mounting hole 40 to accommodate it, making it easy to retrieve the drain connector when installing the air conditioner for the user, improving assembly efficiency; at the same time, it improves the space utilization of the chassis protection device.

[0040] In one embodiment, referring to Figures 1 to 3As shown, the main body 1 is also provided with a clearance groove 50. The clearance groove 50 is located on one side of the main body 1 and is set close to the edge of the main body 1. The clearance groove 50 is formed by the upper end of the main body 1 being recessed downward, and is used to avoid the valve cover of the air conditioner. Specifically, the main body 1 is also provided with a clearance groove 50, which is used to avoid the valve cover of the outdoor unit of the air conditioner, so as to prevent the valve cover from colliding with the main body 1. The clearance groove 50 is located on one side of the main body 1 and is set near the edge of the main body 1. Since the valve cover is located in the middle of one side of the outdoor unit of the air conditioner, the clearance groove 50 is set in the middle of one side of the main body 1, and the clearance groove 50 is formed by the upper end of the main body 1 being recessed downward. When the outdoor unit of the air conditioner is assembled onto the main body 1, the valve cover and the clearance groove 50 are arranged opposite each other, and the clearance groove 50 is located below the valve cover to make room for it, so as to avoid interference between the main body 1 and the valve cover, improve assembly efficiency and protect the main body 1.

[0041] More specifically, the clearance groove 50 is located between the two mounting grooves 20, that is, the mounting grooves 20 are respectively provided on both sides of the clearance groove 50, thereby improving the structural stability of the main body 1.

[0042] In a specific embodiment, refer to Figures 1 to 3 As shown, the main body 1 is also provided with a plurality of limiting blocks 60. The plurality of limiting blocks 60 are arranged along the circumference of the main body 1 at the edge of the main body 1, and the limiting blocks 60 are arranged to protrude upward from the upper end surface of the main body 1. Specifically, a plurality of limiting blocks 60 are also provided at the edge of the main body 1. The limiting blocks 60 are arranged to protrude upward from the upper end surface of the main body 1, so that the limiting blocks 60 are higher than the upper end surface of the main body 1, thereby limiting the outdoor unit of the air conditioner to achieve better protection for the outdoor unit of the air conditioner and preventing the outdoor unit of the air conditioner from shifting. Moreover, the plurality of limiting blocks 60 are arranged at intervals along the circumference of the main body 1 at the edge of the main body 1, thereby limiting the outdoor unit of the air conditioner around its perimeter, thereby improving the limiting effect of the limiting blocks 60 on the outdoor unit of the air conditioner and preventing the outdoor unit of the air conditioner from shaking.

[0043] The thickness and height of the limiting block 60 can be determined according to the outer shell and bottom shell structure dimensions and protective effect of the outdoor unit of the air conditioner.

[0044] More specifically, refer to Figures 1 to 3As shown, the main body 1 is also provided with a plurality of material reduction holes 80, which are located between the two relief grooves 10 and penetrate the upper and lower end faces of the main body 1. The material reduction holes 80 are mainly concentrated in the middle of the main body 1, and are opened in the part of the main body 1 where the stress is not great. Material reduction is achieved in the part of the main body 1 where the stress is not great, i.e., a hollow design is adopted, which can reduce the production cost of the main body 1.

[0045] More specifically, the actual casing and chassis structure of the outdoor unit of the air conditioner can be adjusted to allow for additional space or to add bulges to improve its load-bearing capacity.

[0046] In one embodiment, referring to Figure 6 As shown, a layer of composite paperboard 70 is fixed on the outer surface of the main body 1. Specifically, composite paperboard 70 refers to paperboard made of two or more types of paperboard through a specific process; composite paperboard 70 has several characteristics, including high strength, able to withstand greater pressure and weight; good moisture resistance, effectively protecting the contents from moisture; and environmentally friendly and biodegradable: not only is it environmentally friendly during use, but it can also naturally degrade after disposal, reducing pollution.

[0047] Since the main body 1 is located at the bottom of the outdoor unit of the air conditioner, it is in direct contact with the ground when subjected to force. Under the influence of friction and other forces, the main body 1 is prone to cracking. Therefore, in order to protect the main body 1, a layer of composite cardboard 70 is fixed on the outer surface of the main body 1. The outer surface of the main body 1 refers to the lower end face of the main body 1 and the four sides connecting the upper end face and the lower end face of the main body 1, thereby improving the structural strength and durability of the main body 1, avoiding the easy cracking of the main body 1, and increasing the service life of the main body 1.

[0048] More specifically, the thickness of the composite paperboard 70 is 0.88mm. Setting the thickness of the composite paperboard 70 to 0.8mm can improve the strength and durability of the main body 1, ensuring the strength of the paperboard without making it too thick and heavy, facilitating its use and transportation, and ensuring that the cost is not too high.

[0049] In this embodiment, the composite paperboard 70 and the main body 1 are fixed by adhesive application, and multiple adhesive application points are spaced apart circumferentially along the main body 1. This method is low-cost and simple to operate. For example, hot melt adhesive is used to apply the composite paperboard 70 to the foam, ensuring that all four sides are firmly adhered.

[0050] In this embodiment, the composite paperboard 70 is made of yarn tube paperboard, and both sides of the yarn tube paperboard are covered with kraft paper. The yarn tube paperboard is a type of paperboard with strong pressure resistance and good tensile strength. Kraft paperboard has high burst strength, ring crush strength, and tear resistance, making it very suitable for increasing the strength and toughness of paperboard. At the same time, the basis weight of the kraft paperboard is greater than or equal to 120 g / m³. 2 This ensures that the paperboard has sufficient strength, thereby guaranteeing that the composite paperboard 70 enhances the strength of the main body 1.

[0051] In a specific embodiment, refer to Figure 6 As shown, the outer surface of the composite paperboard 70 is further provided with a film layer of PE or PP material. Specifically, to solve the problem of corrosion and softening of the composite paperboard 70 in humid environments, in this embodiment, a film layer of PE or PP material is further provided on the outer surface of the composite paperboard 70. PE material is polyethylene, a thermoplastic resin obtained by polymerizing ethylene. It is odorless, tasteless, and non-toxic, with a waxy feel. It is a particularly high-molecular-weight material with good chemical stability, resisting the erosion of most acids and alkalis, and has low water absorption and excellent electrical insulation. Due to these properties, PE material is widely used in industry, agriculture, packaging, and daily life. PP material, or polypropylene, is also a very common thermoplastic plastic with a stable molecular structure, thus possessing excellent durability. PP material is lightweight, chemically resistant, and heat-resistant. The outer surface of the composite paperboard 70 refers to the side away from the main body 1. The PE and PP materials are common plastic materials with good waterproof, moisture-proof and wear-resistant properties, making them very suitable as outer surface films for paperboard. By coating or laminating the outer surface of the composite paperboard 70, the moisture resistance, wear resistance and aesthetics of the composite paperboard 70 can be effectively improved.

[0052] Meanwhile, if the thickness of the film layer is greater than or equal to 0.018 mm, it ensures that the film layer on the outer surface of the composite paperboard 70 is thick enough, thereby providing better protection. A film layer that is too thin may not be able to effectively resist external abrasion and moisture, while a film layer with sufficient thickness can better protect the items inside the paperboard.

[0053] Furthermore, the bursting strength of the film layer is greater than or equal to 550 kPa. Bursting strength is an important indicator for measuring the strength of the composite paperboard 70. It refers to the maximum pressure that the composite paperboard 70 can withstand per unit area under specific test conditions. The bursting strength of 550 kPa specified in this embodiment means that the composite paperboard 70 can still remain intact and will not break when subjected to greater pressure, thus improving the strength of the main body 1.

[0054] This embodiment also provides an air conditioner (not shown in the figure), which includes a chassis and a chassis protection device. The chassis protection device can be any kind of chassis protection device provided by this utility model. Since the specific structure and working principle of the chassis protection device have been described in detail in the previous description, they will not be repeated here for the sake of brevity. The chassis protection device is installed under the chassis.

[0055] Specifically, the air conditioner includes a chassis and a chassis protection device. The fixing block of the chassis is embedded in the relief groove 10, thereby achieving a fixed connection between the chassis and the chassis protection device and preventing the chassis from detaching from the chassis protection device.

[0056] The air conditioner in this embodiment uses the chassis protection device provided by this utility model. The chassis protection device can prevent the chassis from deforming due to stress. In addition, the chassis protection device has a high space utilization rate, thereby improving the service life of the air conditioner chassis and facilitating the installation of the air conditioner by the installer, thus improving the installation efficiency.

[0057] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any person skilled in the art can easily conceive of various equivalent modifications or substitutions within the technical scope disclosed in this utility model, and these modifications or substitutions should all be covered within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
