[0037] like Figures 1 to 12 As shown, an embodiment of the utility model provides a chassis 100 of a heat pump unit, comprising a housing 10 and a top cover assembly, wherein:

[0038] like Fig.10 As shown, the shell 10 has a accommodating cavity 11 for accommodating functional parts of the heat pump unit. The top of the shell 10 is provided with a first opening 12. When the chassis 100 is placed normally, the first opening 12 is formed above the shell 10 in the direction of gravity. The shape and size of the first opening 12 can be determined according to actual needs and are not limited here.

[0039] The top cover assembly is a split structure, including a top cover 20 and a reinforcement member 30. The top cover 20 and the housing 10 are detachably sealed. Figure 4 As shown, when the top cover 20 is assembled with the shell 10, the top cover 20 can cover the first opening 12, the shape of the reinforcement 30 is adapted to the edge shape of the top cover 20, the reinforcement 30 is connected to the top cover 20 and is arranged around the first opening 12, and the reinforcement 30 at least partially overlaps with the top cover 20 in the horizontal direction, so that the top cover 20 can be supported from the inside. The reinforcement 30 can be made of a material with higher strength, and the top cover assembly is connected to the shell 10 through the reinforcement 30. On the one hand, the reinforcement 30 can strengthen the strength of the top cover 20 itself to prevent the top cover 20 from being deformed when impacted by external force, and on the other hand, it can enhance the stability and reliability of the connection between the top cover 20 and the shell 10, thereby improving the structural strength of the heat pump unit chassis 100.

[0040] Furthermore, the reinforcement member 30 and the top cover 20 are detachably connected to facilitate assembly, replacement and maintenance. The reinforcement member 30 can also play a decorative role. Specifically, refer to Figure 3 As shown, when the top cover 20 is covered on the first opening 12, at least part of the outer circumferential surface of the reinforcement 30 is exposed between the shell 10 and the top cover 20. When the user observes the chassis 100, the reinforcement 30 can be observed intuitively. The user can choose reinforcements 30 with different appearances (such as colors or shapes) for replacement according to preference. Alternatively, the reinforcement 30 can serve as an identification. Chassis 100 of different types or uses use reinforcements 30 with different appearances.

[0041] In the embodiments provided by the present utility model, refer to Figure 4 as well as Figure 5As shown, the top cover 20 includes a top wall 21 and a first side wall 22 arranged around the top wall 21, one end of the first side wall 22 is connected to the top wall 21, and the other end of the first side wall 22 extends toward the direction of the top wall 21 facing the first opening 12, and the top wall 21 and the first side wall 22 together form an installation cavity. In a feasible embodiment, the top cover 20 and the first side wall 22 are integrally formed sheet metal parts, the top cover 20 extends in a horizontal direction, and the first side wall 22 is formed by bending the edge of the top cover 20 downward, and the contour surface of the first side wall 22 is adapted to the contour surface of the top cover 20.

[0042] Reference Figure 6 as well as Figure 7 As shown, the reinforcement member 30 includes a second side wall 31 disposed around the first opening 12 and a first matching portion 32 located on a side of the second side wall 31 close to the top wall 21. The second side wall 31 is fitted with the first side wall 22. Figure 4 As shown, at least a portion of the second side wall 31 extends into the installation cavity, the second side wall 31 can be embedded inside the first side wall 22, and the first matching portion 32 is detachably connected to the supporting portion 23.

[0043] On the one hand, the support portion 23 can increase the structural strength of the top cover 20. Under the joint action of the support portion 23 and the reinforcement 30, the structural strength of the top cover 20 is improved. On the other hand, it is convenient to disassemble the top cover 20 and the shell 10, thereby improving the assembly efficiency of the top cover 20 and the shell 10.

[0044] In a feasible implementation mode, referring to Figure 5 , Figure 6 as well as Figure 7As shown, a plurality of first mounting holes 321 are provided on the first matching portion 32, and a plurality of second mounting holes 231 are provided on each supporting portion 23, each first mounting hole 321 corresponds to each second mounting hole 231 one by one, and the axes of the first mounting hole 321 and the corresponding second mounting hole 231 coincide with each other, so as to allow the bolt member to pass through the first mounting hole 321 and the second mounting hole 231 in sequence and then be threadedly connected. Preferably, a support portion 23 is provided on each wall surface of the first side wall 22. In the embodiment provided by the utility model, the cross-section of the first side wall 22 is a square structure. A total of four support portions 23 are provided on the first side wall 22. Each support portion 23 is provided with at least two second mounting holes 231. The four support portions 23 are respectively connected to the four sides of the reinforcement 30. A corresponding number of first mounting holes 321 are provided at the connection between the reinforcement 30 and the support portion 23. Each first mounting hole 321 is threadedly connected with each second mounting hole 231 after a bolt passes through it, so that the reinforcement 30 is connected to the top cover 20 through the connection with the support portion 23. The bolt connection of multiple first mounting holes 321 and multiple second mounting holes 231 can improve the connection strength between the top cover 20 and the reinforcement 30 and improve the assembly efficiency.

[0045] In the embodiment provided by the utility model, a snap-fit ​​is formed between the shell 10 and the reinforcement 30, wherein one of the shell 10 and the reinforcement 30 is provided with a slot 13, and the other is provided with a hook 33, and the hook 33 at least partially extends into the slot 13 and snap-fits with the slot 13, so that the reinforcement 30 is preliminarily connected to the shell 10.

[0046] In a feasible implementation mode, referring to Figure 6 , Figure 7 , Fig.10 as well as Fig.11 As shown, the hook 33 is provided on the side of the reinforcement member 30 facing the housing 10, and the slot 13 is provided at the outer circumferential edge of the housing 10 at the first opening 12. Preferably, the hooks 33 are evenly distributed around the reinforcement member 30, and the slots 13 are evenly distributed at the edge of the first opening 12, and the positions of the hooks 33 and the slots 13 correspond one to one. Each hook 33 is connected to each slot 13 in a snap-fit ​​manner to achieve a detachable connection between the reinforcement member 30 and the housing 10.

[0047] Reference Figure 8 as well as Fig. 9 As shown, the hook 33 includes a first plate 331 and a second plate 332. The first end of the first plate 331 is connected to the reinforcement 30, and the second end of the first plate 331 is connected to the first end of the second plate 332. The first plate 331 and the second plate 332 are connected to form an "L"-shaped structure.

[0048] The card slot 13 is a through slot provided on the shell 10. When connecting the reinforcement 30 to the shell 10, the second plate 332 is first inserted into the card slot 13, and then the first plate 331 is pushed in the direction close to the card slot 13 until the reinforcement 30 abuts against the surface of the shell 10. At this time, the second plate 332 passes through the card slot 13 and extends into the inside of the card slot 13. Then, the reinforcement 30 is pushed to make the second plate 332 move along the extension direction of the card slot 13 until the first plate 331 abuts against the end of the card slot 13, thereby realizing the snap connection between the buckle and the card slot 13.

[0049] Further, refer to Figure 8 as well as Fig. 9 As shown, a guiding slope 333 is provided at the second end of the second plate 332, and the guiding slope 333 is provided at a side of the second end of the second plate 332 away from the housing 10. The guiding slope 333 plays a guiding role, and the second plate 332 can be inserted more accurately and smoothly during the insertion of the card slot 13 under the action of the guiding slope 333, thereby making the connection between the first reinforcement member 30 and the housing 10 more convenient and quick.

[0050] After all the hooks 33 and the slots 13 are engaged, the positions of the reinforcement member 30 and the housing 10 need to be fixed to ensure the structural stability of the chassis 100. Figure 6 , Figure 7 as well as Fig.12 As shown, the shell 10 is provided with a first locking portion 15, and the top cover assembly is provided with a second locking portion 34. When the top cover assembly is covered on the first opening 12, the second locking portion 34 is connected to the first locking portion 15, so that the top cover assembly is locked on the shell 10.

[0051] In a feasible implementation mode, referring to Figure 6 , Figure 7 as well as Fig.10 As shown, the first locking portion 15 is a threaded hole 151 arranged on the side wall of the shell 10, and the second locking portion 34 includes a locking plate arranged on the reinforcement 30 and extending to the accommodating cavity 11, and the locking plate is provided with a through hole 341. When the top cover assembly is covered on the first opening 12, the axis of the through hole 341 coincides with the axis of the threaded hole 151, and the bolt can pass through the through hole 341 and be threadedly connected with the threaded hole 151 to achieve assembly and fixation, so that the first reinforcement 30 will not be offset, thereby ensuring the stability of the overall structure of the chassis 100. When disassembling, it is only necessary to unscrew the bolts, which is convenient and quick. The number and position of the first locking portion 15 and the second locking portion 34 can be determined according to actual needs and are not limited here.

[0052] In order to make the chassis 100 better adapt to the outdoor environment and prevent rain from damaging the functional components in the chassis 100, refer to Figures 10 to 12As shown, at least one waterproof member 14 is provided in the housing 10, and the waterproof member 14 is arranged corresponding to the position of the card slot 13. In a feasible implementation, the housing 10 where the card slot 13 is located is a support platform 16 extending in the horizontal direction, and the support platform 16 is a plate structure, and the card slot 13 passes through this plate structure. The waterproof member 14 is connected to this plate structure and is located below the gravity direction of the card slot 13. Each waterproof member 14 is provided with a liquid collecting chamber 141, and the liquid collecting chamber 141 is connected to the card slot 13. Rainwater falling on the chassis 100 can enter the waterproof member 14 through the card slot 13 to collect water, thereby effectively preventing rainwater from damaging the functional parts inside the chassis 100.

[0053] In the embodiments provided by the present utility model, refer to Figure 4 , Figure 6 as well as Figure 7 As shown, the reinforcement member 30 also includes a second matching portion 35, which also extends in the horizontal direction. The second matching portion 35 is closer to the shell 10 than the first matching portion 32. When the top cover assembly is covered on the first opening 12, the second matching portion 35 abuts against the support platform 16. The second matching portion 35 and the support platform 16 are both horizontally extended plate structures, so that the contact portion between the reinforcement member 30 and the shell 10 is surface contact, thereby providing stable support for the reinforcement member 30 and improving the structural strength of the chassis 100. When installing the top cover assembly, after the hook 33 is inserted into the slot 13, the second matching portion 35 abuts against the support platform 16, so that the operator can know that it has been installed in place, and the first locking portion 15 and the second locking portion 34 can be connected at this time.

[0054] Further, refer to Figure 4 as well as Fig.10 As shown, the shell 10 also includes a shielding portion 17, which is connected to the inner peripheral side of the supporting platform 16 and extends toward the top cover 20. The shielding portion 17 is arranged around the first opening 12. After the top cover assembly is assembled on the shell 10, there is an overlapping area between the shielding portion 17 and the reinforcement 30 in the horizontal direction. On the one hand, the shielding portion 17 can play a limiting role to limit the movement of the top cover assembly in the horizontal direction. On the other hand, after external rainwater invades from the gap between the reinforcement 30 and the supporting platform 16, the shielding portion 17 can block rainwater from entering the interior of the chassis 100, which can effectively prevent rainwater from damaging the functional parts inside the chassis 100.

[0055] Based on the chassis 100 provided in the above embodiments, the utility model also provides a heat pump unit, including the chassis 100 of the aforementioned heat pump unit, wherein the accommodating cavity 11 of the chassis 100 is provided with functional parts such as a compressor and a heat exchanger. Since the chassis 100 connects the shell 10 with the top cover assembly by setting a reinforcement member 30, and the reinforcement member 30 is arranged around the first opening 12, the reinforcement member 30 can, on the one hand, strengthen the strength of the top cover 20 itself to prevent the top cover 20 from deforming, and on the other hand, can enhance the stability and reliability of the connection between the top cover 20 and the shell 10, thereby improving the structural strength of the chassis 100.

[0056] The above describes in detail the structure, features and effects of the utility model based on the embodiments shown in the drawings. The above is only a preferred embodiment of the utility model, but the utility model is not limited to the scope of implementation shown in the drawings.
