DETAILED DESCRIPTION

[0032] The following describes the specific embodiments of the present disclosure in detail with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only used to illustrate and explain the present disclosure and are not intended to limit the present disclosure.

[0033] In this disclosure, unless otherwise indicated, "inside" and "outside" refer to the inside and outside relative to the outline of a component or structure. Furthermore, it should be noted that the use of terms such as "first" and "second" is intended to distinguish one element from another and does not imply order or importance. Furthermore, in the description with reference to the accompanying drawings, the same reference numerals in different drawings represent the same element.

[0034] According to a first aspect of the present disclosure, there is provided a chassis of an outdoor unit, Figures 1 to 7 As shown, the chassis of the outdoor unit includes a chassis body 1 and a fixing member 2, the chassis body 1 has a plurality of mounting positions 110; the plurality of mounting positions 110 and the fixing member 2 are constructed to selectively and detachably connect the fixing member 2 to any one or more mounting positions 110, and the fixing member 2 has a fixing portion 210 for fixing the chassis body 1 to an external base.

[0035] Through the above-mentioned technical solution, that is, the chassis of the outdoor unit provided by the present invention, by constructing the chassis body 1 to have multiple installation positions 110, and constructing the fixing parts 2 used to fix the chassis body 1 to the external base to be selectively detachably connected to any one or more installation positions 110 of the chassis body 1, in this way, when the chassis of the outdoor unit is fixedly installed on site, for example, it is convenient for on-site personnel to adaptively arrange the installation position of the fixing parts 2 relative to the chassis body 1 according to different installation and use scenarios, so that the installation direction of the fixing parts 2 can be freely switched according to installation needs during the installation process, which helps to improve the installation adaptability of the chassis of the outdoor unit and has the advantages of convenient and efficient installation.

[0036] It should be noted that the external base (not shown) can be any installation location such as the ground or a load-bearing wall that can be used for stable installation and support of the outdoor unit and the chassis, and the present disclosure does not specifically limit this. In addition, the fixing portion 210 of the fixing member 2 can be, for example, Figure 3 The fixing holes or fixing grooves shown as an example are structures such as fasteners (not shown) such as bolts or screws to pass through and then fix the chassis body 1 and the fixing member 2 to the external substrate through the fasteners, thereby facilitating on-site installation operations.

[0037] In order to improve the installation adaptability of the chassis of the outdoor unit so as to meet different installation and use requirements on site, in some embodiments, reference is made to Figures 1 to 5 As shown, the plurality of mounting positions 110 may include at least two first mounting positions 111 located on opposite sides of the chassis body 1 in the transverse direction and at least two second mounting positions 112 located on opposite sides of the chassis body 1 in the longitudinal direction. In this way, when performing a chassis fixing and installation operation of the outdoor unit on site, for example, it is convenient for on-site personnel to adaptively connect the fixing member 2 to the first mounting position 111 and / or the second mounting position 112 according to different installation and use scenarios. For example, Figure 1 As shown, the fixing member 2 can be completely installed in the second installation position 112, or, as shown, Figure 5 As shown, all the fixing members 2 can also be installed in the first installation position 111, or, in some embodiments not shown in the figures, some of the multiple fixing members 2 can also be installed in the first installation position 111, and the remaining fixing members 2 can be installed in the second installation position 112. The present disclosure does not make specific limitations on this, and those skilled in the art can adaptively arrange the position of the fixing members 2 relative to the chassis body 1 according to actual installation needs.

[0038] Optionally, in some embodiments, reference Figure 1 As shown, the number of the fixing member 2, the first mounting position 111 and the second mounting position 112 can be the same, so that, for example, when the installation in the longitudinal direction is limited, the operator can adaptively remove the fixing member 2 on the second mounting position 112 and adaptively install it on, for example, the first mounting position 111, so as to achieve the purpose of freely switching the installation direction of the fixing member 2 according to installation needs during the installation operation, which helps to improve the installation adaptability of the chassis of the outdoor unit and has the advantages of convenient and efficient installation.

[0039] Of course, the specific embodiment in which the numbers of the above-mentioned fixing parts 2, the first mounting position 111 and the second mounting position 112 can be the same is exemplary. In order to better meet different installation and use requirements on site, the numbers of the above-mentioned fixing parts 2, the first mounting position 111 and the second mounting position 112 can also be different. The specific number is not specifically limited in this disclosure. Those skilled in the art can adaptably design it according to actual application requirements. The purpose is to facilitate on-site installation operations and ensure that the outdoor unit and the chassis are stably fixed to the external base.

[0040] In addition, it should be noted that the specific embodiment in which the plurality of mounting positions 110 are arranged longitudinally and transversely is exemplary, and those skilled in the art can adaptively adjust the arrangement of the plurality of mounting positions 110 in combination with the external structure of the chassis body 1, for example, Figure 1 As shown, when the outer structure of the chassis body 1 is, for example, rectangular, the multiple mounting positions 110 may include at least two first mounting positions 110 located on opposite sides of the chassis body 1 in the transverse direction and at least two second mounting positions 112 located on opposite sides of the chassis body 1 in the longitudinal direction, so as to achieve the purpose of arranging the multiple mounting positions 110 around the four sides of the chassis body 1, for example, in a rectangular shape.

[0041] Of course, in some embodiments not shown in the figures, when the outer structure of the chassis body 1 is, for example, circular, a plurality of mounting positions 110 may also be arranged on the chassis body 1 at equal intervals around the circumference of the circular chassis body 1. The present disclosure does not specifically limit such deformation methods, and those skilled in the art may adaptively design according to actual application requirements, with the aim of ensuring that the outdoor unit and the chassis are stably fixedly connected to the external base.

[0042] Considering that in order to improve the stability of the outdoor unit and the chassis connected to the external base, in some embodiments, reference Figures 1 to 5As shown, the chassis body 1 may include a base plate 120 and a support member 130 connected to the base plate 120, and a first mounting position 111 and / or a second mounting position 112 is provided on the support member 130. In this way, by setting at least one of the first mounting position 111 and the second mounting position 112 on the support member 130 (that is, it can be understood that the above-mentioned first mounting position 111 can be set on the support member 130, and the second mounting position 112 can be set on the base plate 120, or the above-mentioned first mounting position 111 can be set on the base plate 120, and the second mounting position 112 can be set on the support member 130, or the first mounting position 111 and the second mounting position 112 can be set on the support member 130 at the same time), the difficulty of on-site processing and preparation of the chassis body 1 can be reduced, and on-site processing and preparation of the chassis body 1 is facilitated. In addition, by providing the support member 130, it is also easy to improve the stability of the outdoor unit and the chassis connected to the external substrate, which is beneficial to ensure, for example, stable operation of the outdoor unit.

[0043] It should be noted that the connection and fixing method between the base plate 120 and the support member 130 can be, for example, welding or assembly connection using fasteners such as bolts or screws. This disclosure does not specifically limit such deformation methods. Those skilled in the art can adapt the design according to actual application requirements. The purpose is to ensure a high connection reliability between the base plate 120 and the support member 130. In addition, this disclosure does not specifically limit the specific structure of the base plate 120. Those skilled in the art can adapt the specific structure of the base plate 120 according to, for example, the outdoor unit. This disclosure does not elaborate on this in detail.

[0044] For example, in some embodiments, Figure 1 As shown, the number of support members 130 can be two, and the two support members 130 are arranged at intervals along the horizontal or vertical direction, and a first mounting position 111 and a second mounting position 112 are provided on the support member 130. In this way, while the above-mentioned multiple mounting positions 110 can be formed on the chassis body 1, a supporting role can also be played by the two support members 130 arranged at intervals along the horizontal or vertical direction, which is beneficial to improving the operating reliability of the outdoor unit.

[0045] In order to ensure that the support member 130 can be stably supported on the outdoor unit, in some embodiments, reference is made to Figure 1 and Figure 4 As shown, the support member 130 may include a longitudinal beam 131 extending in the longitudinal direction and a transverse beam 132 extending in the transverse direction. The opposite ends of the longitudinal beam 131 are provided with a second mounting position 112. One end of the transverse beam 132 is connected to the longitudinal beam 131, and the other end is provided with a first mounting position 111, which helps to improve the supporting effect of the support member 130, has high reliability and has the advantages of simple structure and easy installation and preparation.

[0046] Optionally, each support member 130 may have multiple cross beams 132 arranged side by side in the longitudinal direction. For example, Figure 1 and Figure 4 As shown, the number of cross beams 132 can be, for example, two and arranged side by side in the longitudinal direction. In this way, the above arrangement can make the support member 130, for example, π-shaped, which can not only ensure that the outdoor unit and the chassis are stably supported by the π-shaped support member 130, but also, when the two π-shaped support members 130 are arranged, for example, in the transverse direction, multiple mounting positions 110 can be formed on the chassis body 1, which facilitates the installation process. The installation direction of the fixing member 2 can be freely switched according to the installation needs, which helps to improve the installation adaptability of the chassis of the outdoor unit. The present disclosure is not limited to this. Those skilled in the art can adaptively design the number of cross beams 132 and longitudinal beams 131 according to actual application needs.

[0047] In addition, in order to facilitate the positioning and installation of the support member 130, in some embodiments, reference is made to Figure 1 、 Figure 4 、 Figure 6 as well as Figure 7 As shown, one of the first positioning portion 3 and the first positioning matching portion 4 can be provided on the support member 130, and the other of the first positioning portion 3 and the first positioning matching portion 4 can be adaptively provided on the base plate 120. In this way, when the support member 130 is installed on the base plate 120, the first positioning portion 3 and the first positioning matching portion 4 are used for positioning and matching, which facilitates the positioning and installation of the support member 130, helps to reduce the difficulty of assembly and improve assembly efficiency.

[0048] Among them, for example, Figure 1 、 Figure 4 、 Figure 6 as well as Figure 7 As shown, the first positioning portion 3 can be a first positioning protrusion 310, and the first positioning mating portion 4 can be a first positioning socket 410 (e.g., a slot or jack structure) that plugs and mates with the first positioning protrusion 310. This structure is simple and facilitates installation. It should be noted that the first positioning mating portion 4 can also be, for example, a positioning protrusion structure, and accordingly, the first positioning portion 3 can be a positioning socket structure. This disclosure does not specifically limit such variations. Those skilled in the art can adapt the design based on actual application requirements, as long as the purpose is to facilitate the positioning and installation of the support member 130.

[0049] In addition, the first positioning portion 3 and the first positioning matching portion 4 may also be adaptively arranged into multiple groups to improve the connection reliability between the support member 130 and the base plate 120 , while helping to reduce assembly difficulty and improve assembly efficiency.

[0050] In addition, it should be noted that the above-mentioned chassis body 1 may include a base plate 120 and a support member 130, and the specific embodiment of setting at least one of the first mounting position 111 and the second mounting position 112 on the support member 130 is exemplary. For example, in some embodiments not shown in the figures, the chassis body 1 can also be constructed as, for example, an integrally molded structural member, and the above-mentioned multiple mounting positions 110 can be directly processed and prepared on the integrally molded chassis body 1. The present disclosure does not specifically limit such deformation methods, and those skilled in the art can design it adaptively according to actual application requirements.

[0051] In order to facilitate the installation of the fixing member 2 and to ensure a high connection reliability between the fixing member 2 and the installation position 110, in some embodiments, reference Figures 1 to 4 As shown, a connection structure 5 can be provided on the installation position 110, and the fixing member 2 can be detachably connected to the connection structure 5, which facilitates the installation operation and has high reliability.

[0052] The connection structure 5 can be designed adaptively according to actual application requirements. For example, in some embodiments, Figure 3 and Figure 4 As shown, the connecting structure 5 may include a first through hole 510 and a connecting member 520 arranged in the first through hole 510, and a second through hole 220 is provided on the fixing member 2, for passing a fastener through the second through hole 220 and then connecting to the connecting member 520, so as to connect the fixing member 2 to the connecting structure 5. For example, the connecting member 520 may be, for example, a rivet nut, and correspondingly, the fastener may be, for example, a rivet, so as to connect the fixing member 2 to the connecting structure 5 by riveting the rivet nut and the rivet, or, alternatively, the connecting member 520 may also be, for example, a nut, and correspondingly, the fastener may be, for example, a bolt, so as to connect the fixing member 2 to the connecting structure 5 by threaded connection of the bolt and the nut. The present disclosure does not specifically limit such deformation methods, and those skilled in the art may design it adaptively according to actual application requirements, with the purpose of being able to stably connect the fixing member 2 to the connecting structure 5.

[0053] In addition, in some embodiments, reference Figure 3 and Figure 4 As shown, the connecting structure 5 may include one of the second positioning portion 530 and the second positioning matching portion 540, and the fixing member 2 is provided with the other of the second positioning portion 530 and the second positioning matching portion 540. In this way, when the fixing member 2 is connected to the connecting structure 5, the second positioning portion 530 and the second positioning matching portion 540 are used for positioning and matching, which facilitates the positioning and installation of the fixing member 2, helps to reduce the difficulty of assembly and improve assembly efficiency.

[0054] Among them, for example, Figure 3 and Figure 4 As shown, the second positioning portion 530 can be a second positioning protrusion 531, and the second positioning mating portion 540 can be a second positioning socket 541 (e.g., a slot or jack structure) that plugs and mates with the second positioning protrusion 531. This structure is simple and facilitates installation. It should be noted that the second positioning mating portion 540 can also be, for example, a positioning protrusion structure, and accordingly, the second positioning portion 530 can be a positioning socket structure. This disclosure does not specifically limit such variations. Those skilled in the art can adapt the design based on actual application requirements, as long as the purpose is to facilitate the positioning and installation of the fixing member 2.

[0055] In addition, in order to improve the connection reliability between the fixing member 2 and the connection structure 5, for example, in some embodiments, reference is made to Figure 3 As shown, the number of the first through holes 510 of the above-mentioned connecting structure 5 can be two, and the two first through holes 510 are symmetrically arranged on both sides of the mounting position 110, for example, the second positioning matching portion 540, which facilitates installation and helps to improve the connection reliability between the fixing member 2 and the connecting structure 5.

[0056] In some embodiments, reference Figures 1 to 5 As shown, the fixing member 2 may include a first plate 230 and a second plate 240 arranged in an L-shape, and the connecting structure 5 may include a fitting surface 550 (the fitting surface 550 is formed as the above-mentioned mounting position 110), the first plate 230 is fitted to the fitting surface 550 and is detachably connected to the connecting structure 5, and a fixing portion 210 is provided on the second plate 240 to enable the fixing member 2 to be stably installed on the connecting structure 5. At the same time, the L-shaped arrangement of the fixing member 2 also facilitates on-site connection of the first plate 230 of the fixing member 2 to the connecting structure 5, and connection of the second plate 240 of the fixing member 2 to the external substrate, which makes installation convenient and efficient, and makes the overall structure of the fixing member 2 relatively simple and convenient for installation and manufacturing.

[0057] In addition, in order to improve the structural strength of the fixing member 2, in some embodiments, reference Figure 3 As shown, the first plate 230 and / or the second plate 240 may be provided with a reinforcement structure 250 , which helps to improve the structural strength of the fixing member 2 and ensures that the chassis body 1 is stably fixed to the external substrate through the fixing member 2 .

[0058] The reinforcement structure 250 may be arranged in any suitable manner. For example, in some embodiments, Figure 3 As shown, the reinforcement structure 250 may include flanges 251 provided on the first plate 230 and the second plate 240 , so as to achieve the purpose of improving the structural strength of the fixing member 2 .

[0059] Alternatively, in some embodiments, Figure 3As shown, the reinforcement structure 250 may also include reinforcement ribs 252 connected between the first plate 230 and the second plate 240 , so as to improve the overall structural strength of the fixing member 2 through the arrangement of the reinforcement ribs 252 .

[0060] Alternatively, in some embodiments, Figure 3 As shown, the reinforcing structure 250 may also include a raised portion 253 arranged on the second plate 240, the raised portion 253 is bent and raised from the second plate 240 toward the side where the first plate 230 is located, and the fixing portion 210 is located on the raised portion 253, which can also achieve the purpose of improving the structural strength of the fixing member 2.

[0061] It should be noted that the specific embodiments of the above-mentioned reinforcement structure 250 can be arranged simultaneously or one of them can be adaptively set. The present disclosure does not make specific limitations here. Its purpose is to improve the overall structural strength of the fixing part 2 by setting the reinforcement structure 250.
