Description

Technical Field

[0001] This invention relates to the field of air conditioning technology, and more specifically to chassis components for air conditioning, air conditioners, and motorhomes. Background Technology

[0002] As living standards continue to improve, people have increasingly higher requirements for their living environment. To achieve a comfortable temperature and humidity environment, air conditioning has become an indispensable appliance in people's lives. Based on their structure, air conditioners can be divided into two types: integrated air conditioners and split-type air conditioners. Integrated air conditioners house the compressor, condenser, expansion unit, and evaporator in a single, separate casing. Split-type air conditioners consist of indoor and outdoor units separated from each other. The indoor heat exchanger and its corresponding indoor fan are located in the indoor unit, while the compressor, outdoor heat exchanger, outdoor fan, and expansion unit are located in the outdoor unit.

[0003] Whether it's a one-piece or split-type air conditioner, the compressor is its core component. The compressor is typically mounted on a chassis. This chassis can be the chassis of the one-piece air conditioner's casing or the chassis of the outdoor unit's casing in a split-type air conditioner. When a one-piece air conditioner or its outdoor unit is transported for an extended period or dropped, the chassis is prone to deformation due to the weight of the compressor, thus affecting the stability of the casing. If the chassis deformation is severe, the compressor is easily damaged, significantly impacting the normal operation of the air conditioner.

[0004] Therefore, a new technical solution is needed in this field to solve the above problems. Summary of the Invention

[0005] To address the technical problem of poor chassis structural strength and easy deformation in existing technologies, this invention provides a chassis assembly for an air conditioner. The chassis assembly includes: a chassis, comprising a chassis body and a chassis flange extending vertically upward along the circumferential edge of the chassis body; a back plate, fixed to the rear of the chassis body, and including a back plate body and a back plate flange extending vertically towards the front of the chassis body along the circumferential edge of the back plate body; and a tie rod, positioned on the left and / or right side of the chassis body, and having a lower end fixed to the chassis flange and an upper end fixed to the back plate flange.

[0006] This invention relates to a chassis assembly for an air conditioner, comprising a chassis, a back plate, and diagonal braces. The chassis includes a chassis body and a chassis flange extending vertically upwards along the circumferential edge of the chassis body. The chassis body is used to mount components such as the air conditioner compressor, providing necessary fixing space and reliable support. The chassis flange not only strengthens the structural strength and bending resistance of the chassis body but also facilitates connection with the back plate and diagonal braces. The back plate is fixed to the rear of the chassis body and includes a back plate body and a back plate flange extending vertically towards the front of the chassis body along the circumferential edge of the back plate body. The back plate body provides protection for components such as the compressor mounted on the chassis. Correspondingly, the back plate flange also improves the structural strength and bending resistance of the back plate body and facilitates connection with the chassis and diagonal braces. Diagonal braces are provided on the left and / or right sides of the chassis body, and the diagonal braces have a lower end fixed to the chassis flange and an upper end fixed to the back plate flange. The installation of diagonal braces enhances the reliability of the connection between the chassis and the back plate, makes the chassis more evenly stressed, improves the structural strength of the chassis, prevents deformation during transportation or use, and thus improves the effectiveness of protecting components such as compressors installed on the chassis.

[0007] In the preferred embodiment of the chassis assembly for an air conditioner described above, the chassis body is provided with a plurality of mounting protrusions spaced apart from each other. Each mounting protrusion is configured to extend vertically upward from the chassis body, and each mounting protrusion is provided with a mounting hole for fixing the compressor of the air conditioner. The installation of the mounting protrusions improves the structural strength of the chassis body, allowing the compressor of the air conditioner to be more firmly and stably fixed to the chassis.

[0008] In the preferred embodiment of the chassis assembly for an air conditioner described above, a reinforcing flange extending in a direction away from the chassis body is formed on the chassis flange near the front portion, and the reinforcing flange is adapted to be positioned near the compressor. The reinforcement flange allows for targeted enhancement of the height of the chassis flange near the compressor, further improving the structural strength and bending resistance of the chassis body.

[0009] In the preferred embodiment of the chassis assembly for an air conditioner described above, a plurality of spaced-apart support protrusions are formed on the circumferential edge of the chassis body near the rear. Each support protrusion is configured to extend vertically upward from the chassis body and abut against the back plate flange to support the back plate. The provision of support protrusions strengthens the rear region of the chassis body. Furthermore, the back plate flange is configured to abut against the support protrusions, rather than directly against the chassis body, reducing the contact area between the back plate and the chassis and preventing excessive vibration and noise from the compressor during operation.

[0010] In the preferred embodiment of the chassis assembly for an air conditioner described above, a plurality of backplate fixing holes spaced apart from each other are formed on the rear chassis flange, each backplate fixing hole being positioned above a corresponding support protrusion. This arrangement allows the support protrusion to further strengthen the chassis flange near the corresponding backplate fixing hole.

[0011] In the preferred embodiment of the chassis assembly for an air conditioner described above, the tie rod includes: a tie rod body having a lateral edge at the lower end and a vertical edge at the upper end; a lower mounting plate configured to extend vertically along the lateral edge in a direction away from the tie rod body and abut against the lower surface of the chassis body; and an upper mounting plate configured to extend vertically along the vertical edge in a direction away from the tie rod body and abut against the rear surface of the back panel body. The provision of the upper and lower mounting plates facilitates the fixed installation of the tie rod to the chassis and back panel. Furthermore, the fact that the upper and lower mounting plates abut against the chassis body and back panel body respectively improves the reliability of the tie rod assembly.

[0012] In the preferred embodiment of the chassis assembly for an air conditioner described above, a vertically upward extending limiting protrusion is formed on the chassis body to create a limiting cavity on the lower surface that can receive the lower mounting plate. The limiting protrusion enhances the structural strength at the connection between the chassis body and the lower mounting plate. Furthermore, the limiting cavity facilitates the positioning and installation of the lower mounting plate, improving assembly efficiency and accuracy.

[0013] In the preferred embodiment of the chassis assembly for an air conditioner described above, a vertically downward extending positioning flange is formed on the limiting protrusion, and the positioning flange is configured to abut against a circumferential edge of the lower mounting plate. The positioning flange facilitates the positioning and installation of the lower mounting plate, further improving assembly efficiency and accuracy.

[0014] In the preferred embodiment of the chassis assembly for the air conditioner described above, a snap-fit ​​flange is formed on the upper mounting plate facing the front, and a snap-fit ​​hole is formed on the back plate body to receive the snap-fit ​​flange. The cooperation between the snap-fit ​​flange and the snap-fit ​​hole facilitates the positioning and installation between the upper mounting plate and the back plate, improves the assembly efficiency and accuracy of the upper mounting plate, and makes the two form a more stable connection.

[0015] To address the technical problem of poor chassis structural strength and easy deformation in existing technologies, this invention provides an air conditioner. The air conditioner includes a chassis assembly as described in any of the above-mentioned claims. By employing the chassis assembly described in any of the above-mentioned claims, the air conditioner of this invention can ensure high structural strength of the chassis, improve the reliability of protection for components such as the compressor mounted on the chassis, and thus extend the service life of the air conditioner.

[0016] To address the technical problem of poor chassis structural strength and deformation in existing technologies, this invention provides a motorhome. The motorhome includes the air conditioner described above. By employing the air conditioner, this invention ensures high chassis structural strength, extends the lifespan of the air conditioner, and improves the user experience. Attached Figure Description

[0034] To address the technical problem of poor chassis structural strength and easy deformation in existing technologies, this invention provides a chassis assembly 2 for an air conditioner 1. The chassis assembly includes: a chassis 20, comprising a chassis body 21 and a chassis flange 22 extending vertically upward along the circumferential edge of the chassis body 21; a back plate 30, fixed to the rear of the chassis body 21, and including a back plate body 31 and a back plate flange 32 extending vertically towards the front of the chassis body 21 along the circumferential edge of the back plate body 31; and a tie rod 40, positioned on the left and / or right side of the chassis body 21, and having a lower end fixed to the chassis flange 22 and an upper end fixed to the back plate flange 32.

[0035] In this article, unless explicitly stated otherwise, the terms "left," "right," "front," "back," "up," and "down" are based on... Figure 1 Regarding the directions shown.

[0036] Figure 1 This is a front view of a partial structure of an embodiment of the air conditioner of the present invention. (See attached image.) Figure 1 As shown, in one or more embodiments, the air conditioner 1 of the present invention includes a chassis assembly 2 and a compressor 11 mounted on the chassis assembly 2. The air conditioner 1 can be an integrated air conditioner, a split air conditioner, or other suitable air conditioner. The air conditioner 1 also includes, but is not limited to, components such as a condenser, an expansion device, and an evaporator (all not shown in the figure). The compressor 11 is sequentially connected to the condenser, the expansion device, and the evaporator via refrigerant piping, forming a refrigeration circuit that allows the refrigerant to circulate within it. In one or more embodiments, the air conditioner 1 also includes a four-way valve (not shown in the figure) that can control the refrigerant reversal, allowing the air conditioner 1 to perform cooling and heating according to actual needs.

[0037] See also Figure 1In one or more embodiments, the compressor 11 is a rotary compressor. Alternatively, the compressor 11 may also be a reciprocating compressor, an axial compressor, a centrifugal compressor, or other suitable compressor. In one or more embodiments, three mounting feet 111 are formed at evenly spaced intervals on the bottom of the compressor 11. Each mounting foot 111 is configured to be secured to the chassis assembly 2 by suitable fasteners (e.g., bolts, nuts, etc.). Alternatively, the number of mounting feet 111 may be set to other suitable numbers, more or less than three, such as two, four, etc.

[0038] Below, in conjunction with Figures 1-11 This invention provides a detailed description of embodiments of the chassis assembly 2 used in an air conditioner 1.

[0039] like Figure 1 As shown, in one or more embodiments, the chassis assembly 2 includes components such as a chassis 20, a back plate 30, and a tie rod 40. The chassis 20 is used to mount components such as a compressor 11. The back plate 30 is fixed to the rear of the chassis 20 and is used to cover and protect the components. In one or more embodiments, the tie rod 40 includes a left tie rod 40a located on the left side of the chassis 20 and a right tie rod 40b located on the right side of the chassis 20. In one or more embodiments, the left tie rod 40a and the right tie rod 40b are arranged symmetrically with respect to the chassis 20, so that the chassis 20 is subjected to more even force. Each of the left tie rod 40a and the right tie rod 40b has an upper end and a lower end. The lower end is connected to the chassis 20, while the upper end is connected to the back plate 30. Alternatively, the tie rod 40 may also include only one of the left tie rod 40a and the right tie rod 40b, for example, only the left tie rod 40a or only the right tie rod 40b.

[0040] Figure 6 This is a front structural schematic diagram of an embodiment of the chassis of the chassis assembly for an air conditioner according to the present invention; Figure 7 This is a schematic diagram of the rear structure of an embodiment of the chassis assembly for an air conditioner according to the present invention; Figure 8 yes Figure 7 The diagram shows a partial enlarged view of section C of an embodiment of the chassis assembly for an air conditioner according to the present invention. (See diagram for reference.) Figures 6-8 As shown, in one or more embodiments, the chassis 20 includes a chassis body 21 and a chassis flange 22 formed on the chassis body 21. The chassis body 21 and the chassis flange 22 can be manufactured from a suitable metal material (e.g., stainless steel) through machining processes. The chassis body 21 is a generally rectangular plate structure to provide suitable installation space and strong support for components such as the compressor 11, heat exchanger (not shown), and heat exchanger fan (not shown).

[0041] See also Figure 6In one or more embodiments, three spaced-apart mounting protrusions 211 are provided on the right side of the chassis body 21. Alternatively, the mounting protrusions 211 may also be provided on the left side of the chassis body 21 or at other suitable locations. Each mounting protrusion 211 is configured to extend vertically upward from the chassis body 21. The mounting protrusion 211 may be manufactured by stamping. Each mounting protrusion 211 also has a corresponding mounting hole 2112 to mate with suitable fasteners (e.g., bolts, nuts, etc.) to securely fix the mounting base 111 of the compressor 11 to the chassis body 21. Alternatively, the number of mounting protrusions 211 may be set to other suitable numbers, such as two or four, as long as they can mate with the mounting base 111 of the compressor 11. The provision of mounting protrusions 211 can enhance the strength of the area of ​​the chassis body 21 used for mounting the compressor 11, ensuring the reliability of the compressor 11 installation. It should be noted that during long-term transportation or use, the chassis body 21 is prone to deformation due to the weight of the compressor 11. The installation protrusion 211 effectively improves the bending resistance of the chassis body 21 in the area where the compressor 11 is installed, preventing deformation. In one or more embodiments, a vertically extending reinforcing mounting protrusion 2111 is further provided on the mounting protrusion 211, and a mounting hole 2112 is provided on the reinforcing mounting protrusion 2111. Through the above-mentioned design, the strength and bending resistance of the chassis body 21 can be further improved.

[0042] See also Figure 6 In one or more embodiments, a bracket mounting protrusion 212 is provided in the middle of the chassis body 21. The bracket mounting protrusion 212 is configured to extend vertically upward from the chassis body 21. The bracket mounting protrusion 212 may be manufactured by a stamping process. A bracket mounting hole 2121 is formed on the bracket mounting protrusion 212 to mate with suitable fasteners (e.g., bolts, nuts, etc.) to mount the bracket 50 (see...). Figure 1 The bracket is fixed to the chassis body 21. The bracket mounting protrusion 212 strengthens the structural strength of the chassis body 21 and prevents deformation caused by excessive pressure on the chassis body 21 in the area where the bracket is mounted. In one or more embodiments, a vertically extending reinforcing bracket mounting protrusion 2122 is also formed on the bracket mounting protrusion 212 to further strengthen the structural strength and bending resistance of the chassis body 211 in the area where the bracket is mounted.

[0043] See also Figure 6In one or more embodiments, four spaced-apart support protrusions 213 are provided at the rear of the chassis body 21 near its circumferential edge. Each support protrusion 213 is configured to extend vertically upward from the chassis body 21. The support protrusions 213 may be manufactured by stamping. Each support protrusion 213 is configured to abut against the back flange 32 of the back plate 30 to support the back plate 30. The provision of support protrusions 213 can reduce the contact area between the chassis 20 and the back plate 30, preventing the compressor 11 from generating excessive vibration and noise during operation. Alternatively, the number of support protrusions 213 may be set to other suitable numbers, such as more or less than four, for example, three, five, etc.

[0044] See also Figures 6-8 In one or more embodiments, symmetrically arranged limiting protrusions 214 are formed on the left and right sides of the chassis body 21. The limiting protrusions 214 are positioned near the circumferential edge of the chassis body 21 and are configured to extend vertically upwards from the chassis body 21. That is, the lower surface 215 of the chassis body 21 is the lower surface of the limiting protrusions 214. The limiting protrusions 214 can be manufactured using a stamping process. The provision of the limiting protrusions 214 can enhance the structural strength and bending resistance at the connection between the chassis body 21 and the tie rod 40. Furthermore, the limiting protrusions 214 can also form a limiting cavity 2141 on the downward-facing lower surface 215 of the chassis body 21, serving to receive the lower mounting plate 43 of the tie rod 40, thereby improving the assembly efficiency and accuracy of the lower mounting plate 43. That is, the downward-facing lower surface of the limiting protrusions 214 forms the bottom surface of the limiting cavity 2141. In one or more embodiments, a generally rectangular through hole 2142 is formed on the limiting protrusion 214, and a positioning flange 2143 extending vertically downward from the limiting protrusion 214 is formed on one edge of the through hole 2142. During assembly, the positioning flange 2143 can easily abut against the lower mounting plate 43, thereby further improving the assembly efficiency and assembly accuracy of the lower mounting plate 43. Alternatively, the positioning flange 2143 can also adopt other suitable structures, such as being directly welded to the lower surface of the limiting protrusion 214.

[0045] like Figure 6 As shown, in one or more embodiments, the chassis flange 22 is configured to extend vertically upward along the circumferential edge of the chassis body 21 to enhance the structural strength and bending resistance of the chassis body 21, while also facilitating a fixed connection with the tie rod 40. Chassis connection grooves 221 for mounting the left tie rod 40a and the right tie rod 40b are formed on the left and right sides of the chassis flange 22, respectively. Figure 8As shown, the chassis connecting groove 221 is formed by bending inward from the chassis flange 22, allowing the tie rod body 41 of the tie rod 40 to easily abut against the chassis connecting groove 221, facilitating the positioning and installation of the tie rod 40. Two chassis connecting holes 2211 are formed in the chassis connecting groove 221, spaced apart from each other. Each chassis connecting hole 2211 has a generally hexagonal shape. Alternatively, the chassis connecting holes 2211 can also be circular or other suitable shapes. Each chassis connecting hole 2211 can be fitted with a suitable fastener (e.g., bolt, nut, etc.) to secure the tie rod 40 to the chassis flange 22. Alternatively, the number of chassis connecting holes 2211 can be set to more or less than two, such as one, three, etc.

[0046] See also Figure 6 In one or more embodiments, a reinforcing flange 222 is further provided at the front of the chassis flange 22. This reinforcing flange 222 is formed near the compressor 11 and is configured to extend vertically upwards (in a direction away from the chassis body 21) from the chassis flange 22. In other words, the height of the chassis flange 22 near the compressor 11 (i.e., the reinforcing flange 222) is higher than that of the chassis flange 22 at other locations. This arrangement further enhances the structural strength and bending resistance of the chassis flange 22 in the region near the compressor 11.

[0047] See also Figure 6 In one or more embodiments, four backplate fixing holes 223 are formed at evenly spaced intervals on the rear of the chassis flange 22. Each backplate fixing hole 223 has a generally circular shape. Alternatively, the backplate fixing holes 223 may also be hexagonal or other suitable shapes. Each backplate fixing hole 223 is configured to mate with a suitable fastener (e.g., bolt, nut, etc.) so that the chassis flange 22 can be easily fixedly connected to the backplate 30. Alternatively, the number of backplate fixing holes 223 may be set to more or less than four, such as three, five, etc. In one or more embodiments, each backplate fixing hole 223 is positioned above a corresponding support protrusion 213, so that the support protrusion 213 can correspondingly enhance the structural strength of the chassis flange 22 and mitigate the strength reduction caused by the through holes in the chassis flange 22.

[0048] Figure 9 This is a schematic diagram of the rear structure of an embodiment of the back panel of the chassis assembly for an air conditioner according to the present invention. Figure 9 As shown, in one or more embodiments, the backplate 30 includes a backplate body 31 and a backplate flange 32 formed on the backplate body 31. The backplate body 31 and the backplate flange 32 can be manufactured from a suitable metal material (e.g., stainless steel) using machining processes. The backplate body 31 is a generally rectangular plate structure. Based on Figure 1 As shown, the backplate flange 32 is configured to extend vertically from the circumferential edge of the backplate body 31 toward the front of the chassis 20. (As indicated...) Figure 1 As shown, in the assembled state, the back plate 30 is fixed to the rear of the chassis 20, and the back plate body 31 is substantially perpendicular to the chassis body 21. The back plate flange 32 abuts against the chassis body 21. In one or more embodiments, the back plate flange 32 abuts against the support protrusion 213 of the chassis body 21 to prevent the compressor 111 fixed to the chassis body 21 from causing excessive vibration and noise during operation.

[0049] See also Figure 9 In one or more embodiments, a grille (not shown) with vent holes is formed on the back panel body 31. The grille is positioned opposite to a heat exchanger mounted on the chassis body 21 so that the heat exchanger can easily exchange heat with the external environment, thereby improving the heat exchange efficiency of the air conditioner 1.

[0050] See also Figure 9 In one or more embodiments, two bracket mounting points 312 for fixing the bracket 50 are further provided in the middle of the back plate body 31. These two bracket mounting points 312 are spaced apart from each other in the vertical direction. Three fixing holes (not shown in the figure) are formed in each bracket mounting point 312. Each fixing hole 313 is configured to mate with a suitable fastener (e.g., bolt, screw, etc.) to fix the back plate mounting part 52 of the bracket 50 to the back plate body 31. Alternatively, the fixing holes may be provided in other suitable numbers, more or less than three, such as two, four, etc.

[0051] See also Figure 9 In one or more embodiments, four chassis mounting holes 313 spaced apart from each other in the left-right direction are formed on the bottom of the backplate body 31. Each chassis mounting hole 313 can be opposite to a corresponding backplate mounting hole 223 on the chassis flange 22, so that the backplate body 31 can be easily fixed to the chassis flange 22 by suitable fasteners (e.g., bolts, nuts, etc.). Alternatively, the number of chassis mounting holes 313 can also be set to other suitable numbers, more or less than four.

[0052] Figure 10 yes Figure 9 The image shown is a partial enlarged view of section D of an embodiment of the back panel of the chassis assembly for an air conditioner according to the present invention. (See attached image.) Figure 9 and Figure 10As shown, in one or more embodiments, symmetrically arranged snap-fit ​​protrusions 311 are provided on the left and right sides of the backplate body 31. Each snap-fit ​​protrusion 311 is configured to extend vertically from the backplate body 31 toward the front of the chassis body 21. The snap-fit ​​protrusions 311 are positioned near the circumferential edge of the backplate body 31 to mate with the upper mounting plate 42 of the tie rod 40. The snap-fit ​​protrusions 311 can be manufactured by stamping. The snap-fit ​​protrusions 311 can enhance the structural strength and bending resistance at the connection between the backplate body 31 and the tie rod 40. In addition, the snap-fit ​​protrusions 311 can also form a snap-fit ​​cavity 3111 on the rear surface 314 of the backplate body 31 for receiving the upper mounting plate 42, thereby improving the assembly efficiency and assembly accuracy of the upper mounting plate 42. That is, the rear surface 314 of the backplate body 31 forms the rear surface of the snap-fit ​​protrusion 311, and the rear surface of the snap-fit ​​protrusion 311 forms the bottom surface of the snap-fit ​​cavity 3111. In one or more embodiments, a generally rectangular snap-fit ​​hole 3112 is also formed on the snap-fit ​​protrusion 311. The snap-fit ​​hole 3112 is configured to receive the snap-fit ​​flange 421 on the upper mounting plate 42, so as to further improve the assembly efficiency and connection reliability of the upper mounting plate 42 and the backplate body 31.

[0053] like Figure 9 and Figure 10 As shown, in one or more embodiments, symmetrically arranged backplate connecting grooves 321 are provided on the left and right sides of the backplate flange 32 to facilitate the installation of corresponding left diagonal tie rods 40a and right diagonal tie rods 40b. Figure 10 As shown, the backplate connecting groove 321 is configured to recess from the left (or right) side of the backplate flange 32 toward the center of the backplate body 31 to form a cavity (not shown) that can receive the corresponding tie rod 40, thereby improving the assembly efficiency of the tie rod 40. In one or more embodiments, two backplate connecting holes 3211 spaced apart from each other are formed on the backplate connecting groove 321. Each backplate connecting hole 3211 has a generally hexagonal shape. Alternatively, the backplate connecting holes 3211 may also be circular or other suitable shapes. Each backplate connecting hole 3211 is configured to mate with a suitable fastener (e.g., bolt, nut, etc.) to secure the tie plate 40 to the backplate flange 32.
