Description

Technical Field

[0001] This utility model relates to the field of heat pump technology, and in particular to a fixing buckle, chassis assembly and heat pump equipment. Background Technology

[0002] Heat pump equipment is mainly used to absorb heat from the outdoor ambient air to circulate and heat water in heating devices or water heaters. A heat pump unit generally consists of a chassis and a heat exchanger. The heat exchanger is connected to the chassis via a fixed bracket, and the heat exchanger is secured to the bracket with screws or bolts. However, during installation, installers typically install the heat exchanger onto the fixed bracket from top to bottom. Inaccurate positioning of the heat exchanger by the fixed bracket necessitates continuous adjustment of the heat exchanger's position to align the connection holes on the heat exchanger with those on the fixed bracket. This process is time-consuming, inefficient, and prone to positional deviations, which can damage the heat exchanger. Utility Model Content

[0003] This invention aims to solve at least one of the technical problems existing in the prior art. To this end, this invention proposes a fixing buckle that can quickly position the heat exchanger and align the heat exchanger's connection holes with the fixing holes, thereby shortening installation time, improving installation efficiency, and effectively avoiding the drawback of heat exchanger damage caused by installation position deviations.

[0004] This utility model also provides a chassis assembly and a heat pump device having the above-mentioned fixing buckle.

This allows the connecting hole on the side plate to be quickly aligned with the fixing hole on the first positioning plate, so that the side plate can be tightly connected to the first positioning plate, thereby realizing the fixed installation of the heat exchanger on the chassis body. The alignment time is short, effectively shortening the installation time and improving the installation efficiency. In addition, the installation position of the heat exchanger is highly accurate, effectively avoiding the disadvantage of damage to the heat exchanger due to deviation in the installation position.

[0012] According to some embodiments of the present invention, the first connecting part further includes a fourth positioning plate, which is connected to one end of the first fixing plate and bent downwards. The fourth positioning plate is used to be inserted into the positioning hole of the chassis body.

[0013] According to some embodiments of the present invention, the second connecting part includes a second fixing plate, a transition plate, and a second positioning plate. The second fixing plate is used to connect with the chassis body. One end of the transition plate is connected to the end of the second fixing plate facing the first positioning plate and extends upward. The second positioning plate is connected to the other end of the transition plate and extends towards the first positioning plate. The first positioning groove is located between the first positioning plate and the second positioning plate. A second positioning groove is formed below the second positioning plate. The second positioning groove and the first positioning groove are located on the same side of the third positioning plate and communicate with each other.

[0014] According to some embodiments of the present invention, the second connecting part further includes a second guide plate, which is connected to the end of the second positioning plate away from the third positioning plate and is arranged at an upward inclination. The end of the second guide plate away from the third positioning plate is higher than the end of the second guide plate that is close to the third positioning plate.

[0015] According to some embodiments of the present invention, the second connecting part is provided with a guide surface on the side facing the first positioning groove.

The two fixing buckles are fixedly connected to the chassis body and are arranged at intervals along a first direction. The first slot of the two fixing buckles faces one end of a second direction. Both the first direction and the second direction are perpendicular to the height direction of the heat exchanger.

[0022] The chassis assembly according to the second aspect of the present invention has at least the following beneficial effects: Because the chassis assembly uses the aforementioned fixing buckle, which is connected to the chassis body, when the heat exchanger is installed onto the chassis body, the side plate of the heat exchanger is inserted into the first positioning groove of the fixing buckle through the first slot in a direction parallel to the first fixing plate, until the side plate abuts against the first positioning plate and the third positioning plate of the fixing buckle. This achieves rapid positioning of the heat exchanger, allowing the connecting holes on the side plate to quickly align with the fixing holes on the first positioning plate, so that the side plate can be securely connected to the first positioning plate. This achieves fixed installation of the heat exchanger onto the chassis body, reducing the time required for alignment, effectively shortening installation time, improving installation efficiency, and ensuring high accuracy in the heat exchanger's installation position, effectively avoiding the drawback of heat exchanger damage due to installation position deviations.

[0028] Fasteners are inserted through the fixing holes and securely connected to the side plate and the first positioning plate.

[0029] The heat pump equipment according to the third aspect embodiment of this utility model has at least the following beneficial effects: Since the heat pump equipment uses the aforementioned chassis assembly, with the fixing buckle connected to the chassis body, when the heat exchanger is installed onto the chassis body, the side plate of the heat exchanger is inserted into the first positioning groove of the fixing buckle through the first slot in a direction parallel to the first fixing plate, until the side plate abuts against the first positioning plate and the third positioning plate of the fixing buckle, thereby achieving rapid positioning of the heat exchanger. This allows the connecting holes on the side plate to be quickly aligned with the fixing holes on the first positioning plate, so that the side plate can be securely connected to the first positioning plate, thus achieving fixed installation of the heat exchanger onto the chassis body. The alignment time is short, effectively shortening the installation time and improving installation efficiency.

[0054] Reference Figures 1 to 9 As shown, the first aspect of this utility model provides a fixing buckle 300, which is applied in a heat pump device. The heat pump device includes at least a chassis body 100 and a heat exchanger 200. The fixing buckle 300 is used to connect the chassis body 100 and the heat exchanger 200 so that the heat exchanger 200 is fixedly installed to the chassis body 100.

[0055] The chassis body 100 serves as a support platform for the installation and positioning of components such as the heat exchanger 200, pipes, pump body, and fan of the heat pump equipment. At the same time, the chassis body 100 is also used to receive the condensate generated by the heat pump equipment during operation.

[0056] The following section uses a heat pump device as the main example to explain in detail the specific structural form of the fixing buckle 300 and the connection relationship between the chassis body 100, the fixing buckle 300 and the heat exchanger 200.

[0057] Reference Figure 1As shown, the heat pump unit includes a chassis body 100 and a heat exchanger 200, with the heat exchanger 200 mounted on the upper side of the chassis body 100. Generally, the length of the heat exchanger 200 is parallel to the front-back direction of the heat pump unit, the width of the heat exchanger 200 is parallel to the left-right direction of the heat pump unit, and the height of the heat exchanger 200 is the same as the height of the heat pump unit, which is the vertical direction. The front-back direction is the first direction, which is perpendicular to the height direction of the heat exchanger 200. The left-right direction is the second direction, which is also perpendicular to the height direction of the heat exchanger 200.

[0058] Reference Figure 1 and Figure 3 As shown, it can be understood that the heat exchanger 200 is installed at the center of the chassis body 100 in the left-right direction. Of course, the relative position of the heat exchanger 200 on the chassis body 100 is allowed to have some error; the heat exchanger 200 can deviate from the center of the chassis body 100 in the left-right direction, depending on the installation position of other components inside the heat pump equipment. Specifically, a cavity 110 is provided at the center of the chassis body 100 in the left-right direction, and the cavity 110 is recessed downwards. If the chassis body 100 is a sheet metal part, the cavity 110 can be formed by downward stamping with a punch during machining. That is, a downwardly protruding bulge structure is machined at the center of the chassis body 100 in the left-right direction, and the upper side of the bulge forms the cavity 110.

[0059] For chassis body 100 which is a plastic part, cavity 110 can be obtained by injection molding.

[0060] The heat exchanger 200 is installed in the cavity 110 of the chassis body 100. The bottom wall of the cavity 110 is flat, and the bottom wall of the cavity 110 serves as the main mounting plane of the heat exchanger 200. That is, the cavity 110 is the initial positioning area of ​​the heat exchanger 200, which can provide the assembly personnel with an indication of the installation position for installing the heat exchanger 200, thus facilitating assembly.

[0061] Reference Figure 8 and Figure 9 As shown, it can be understood that the heat exchanger 200 generally includes heat exchange tubes 220 and two side plates 210. The two side plates 210 are located on the front and rear sides of the heat exchanger 200, respectively. The heat exchange tubes 220 are arranged in a serpentine pattern and pass through the two side plates 210. Generally speaking, the bend at the front side of the heat exchange tubes 220 protrudes forward beyond the front side plate 210, and the bend at the rear side of the heat exchange tubes 220 protrudes backward beyond the rear side plate 210.

[0062] In a cross-section perpendicular to the left-right direction, the side plate 210 has an L-shaped cross-section. Specifically, the side plate 210 includes a first plate 211 and a second plate 212. The first plate 211 is arranged in the vertical direction, and the second plate 212 is connected to the lower end of the first plate 211 and is perpendicular to the vertical direction; that is, the second plate 212 is the bent portion at the lower end of the side plate 210. In the two side plates 210 of the heat exchanger 200, the two second plates 212 are located on opposite sides of the two first plates 211 in the front-back direction. Each of the two first plates 211 is provided with a connecting hole 213, which is used for fasteners such as screws, bolts, and rivets to pass through and fix the heat exchanger 200.

[0063] Reference Figures 1 to 3 As shown, it can be understood that the heat pump equipment also includes a fixing clip 300, which is used to connect the chassis body 100 and the heat exchanger 200. There are two fixing clips 300, both of which are installed on the chassis body 100 and connected to the two side plates 210 of the heat exchanger 200 respectively.

[0064] Two retaining clips 300 are fixedly installed on the bottom wall of the cavity 110. The two retaining clips 300 are spaced apart in the front-to-back direction and are symmetrically arranged in the front-to-back direction. In this way, the cavity 110 can also serve as a preliminary positioning area for the retaining clips 300, providing assembly personnel with an indication of the installation position for installing the retaining clips 300, facilitating assembly. The retaining clips 300 and the chassis body 100 can be connected by welding, snap-fitting, or fasteners such as screws, as long as the retaining clips 300 are fixed to the chassis body 100.

[0065] In this embodiment, the fixing buckle 300 is welded and fixed to the bottom wall of the cavity 110 of the chassis body 100. The process is simple and the connection is stable and reliable.

[0066] It is easy to understand that the chassis body 100 and the two fixing clips 300 are part of the chassis assembly of the heat pump equipment.

[0067] To accurately illustrate the relative positions of the components of the fixing buckle 300, the following detailed description of the specific structure of the fixing buckle 300 will be based on the example of the fixing buckle 300 located at the rear of the chassis body 100.

[0068] Reference Figure 6 and Figure 7 As shown, it can be understood that the fixing buckle 300 includes a first connecting part 310, a second connecting part 320 and a third positioning plate 330. The first connecting part 310 and the second connecting part 320 are arranged at intervals in the front-back direction, and the third positioning plate 330 is connected between the first connecting part 310 and the second connecting part 320.

[0069] The first connecting part 310 includes a first fixing plate 311 and a first positioning plate 312. The first fixing plate 311 is perpendicular to the vertical direction, and the first positioning plate 312 is connected to the front end of the first fixing plate 311 and extends upward. Generally, the first positioning plate 312 is perpendicular to the first fixing plate 311. The upper end of the first fixing plate 311 is provided with a fixing hole 3122, which is used for fasteners such as screws or bolts to pass through, so as to connect with the side plate 210 of the heat exchanger 200 through the fasteners.

[0070] The second connecting portion 320 is located on the side of the first positioning plate 312 opposite to the first fixing plate 311 and is spaced apart from the first positioning plate 312, that is, the second connecting portion 320 is located in front of the first connecting portion 310. Specifically, the second connecting portion 320 includes a second fixing plate 321, which is perpendicular to the vertical direction, and the second fixing plate 321 and the first fixing plate 311 are located on the same plane.

[0071] The third positioning plate 330 is connected between the first positioning plate 312 and the second connecting part 320. Specifically, the third positioning plate 330 is arranged in the vertical direction. Generally, the third positioning plate 330 is perpendicular to the first fixing plate 311 and also perpendicular to the first positioning plate 312. One end of the third positioning plate 330 is connected to the right end of the first positioning plate 312, and the other end is connected to the right end of the second fixing plate 321.

[0072] Therefore, a first positioning groove 340 is defined between the first positioning plate 312, the second connecting part 320 and the third positioning plate 330, and the first positioning groove 340 has a first slot 341 facing to the left, that is, the first slot 341 faces away from the third positioning plate 330.

[0073] The fixing buckle 300 is welded to the chassis body 100. Specifically, the first fixing plate 311 and the second fixing plate 321 both abut against the bottom wall of the cavity 110 and are welded to the bottom wall of the cavity 110, so that the fixing buckle 300 is firmly connected to the chassis body 100.

[0074] Since the two fixing buckles 300 are arranged symmetrically in the front-back direction, the first slots 341 of the two fixing buckles 300 are both facing the left side, that is, the first slots 341 of the two fixing buckles 300 are both facing one end in the second direction, that is, facing the same side of the chassis body 100 in the horizontal direction.

[0075] When installing the heat exchanger 200, place the heat exchanger 200 in the initial positioning area, i.e., the cavity 110, and push the heat exchanger 200 in the left and right direction (i.e., the horizontal direction or the direction perpendicular to the height of the heat exchanger 200). This causes the first plates 211 of the two side plates 210 of the heat exchanger 200 to be inserted into the first positioning grooves 340 through the first slots 341 respectively, until the first plates 211 abut against the third positioning plate 330, thereby positioning the heat exchanger 200 in the left and right direction. It is easy to understand that at this time, the first plate 211 also abuts against the first positioning plate 312, which in turn positions the heat exchanger 200 in the front-rear direction. This allows the heat exchanger 200 to be quickly positioned on the chassis body 100, aligning the connecting hole 213 on the first plate 211 with the fixing hole 3122 on the first positioning plate 312. Then, fasteners such as screws, bolts, or rivets are inserted into the connecting hole 213 and fixing hole 3122 to securely connect the first plate 211 and the first positioning plate 312, thus fixing the heat exchanger 200 to the chassis body 100. During the installation of the heat exchanger 200, the assembly personnel can quickly position the heat exchanger 200 without spending a lot of time and effort aligning the connecting hole 213 with the fixing hole 3122, effectively shortening the installation time and improving installation efficiency. Meanwhile, the first positioning plate 312 positions the heat exchanger 200 in the front-to-back direction, and the third positioning plate 330 positions the heat exchanger 200 in the left-to-right direction. This improves the accuracy of the heat exchanger 200's installation position, thereby avoiding the drawback of damage to the heat exchanger 200 due to deviations in its installation position and effectively protecting the heat exchanger 200.

[0076] As can be seen, the heat exchanger 200 is installed horizontally, that is, the heat exchanger 200 is installed from left to right to the fixing clip 300. This avoids the disadvantage of having to lift the heat exchanger 200 for a long time because the heat exchanger 200 needs to be installed from top to bottom. This can reduce the workload of assembly workers and improve assembly efficiency.

[0077] Reference Figure 6 and Figure 7 As shown, the second connecting portion 320 also includes a transition plate 322 and a second positioning plate 323. The transition plate 322 is connected to one end of the second fixed plate 321 facing the first positioning plate 312, that is, one end of the transition plate 322 is connected to the rear end of the second fixed plate 321, and the transition plate 322 extends upward at an angle towards the first positioning plate 312. The second positioning plate 323 is connected to the other end of the transition plate 322, that is, the second positioning plate 323 is connected to the end of the transition plate 322 facing the first positioning plate 312. The second positioning plate 323 and the first positioning plate 312 are arranged at intervals in the front-rear direction, and the first positioning groove 340 is located between the second positioning plate 323 and the first positioning plate 312.

[0078] The second positioning plate 323 is perpendicular to the vertical direction; therefore, it is located above the plane containing the bottom wall of the second fixing plate 321. When the fixing buckle 300 is fixedly installed on the chassis body 100, the second fixing plate 321 abuts against the bottom wall of the cavity 110, and the second positioning plate 323 is located above and spaced apart from the bottom wall of the cavity 110. Therefore, a second positioning groove 350 is formed between the second positioning plate 323 and the bottom wall of the cavity 110; that is, the second positioning groove 350 is located below the second positioning plate 323. In other words, the second positioning groove 350 is the space between the second positioning plate 323 and the chassis body 100.

[0079] It is easy to understand that the second positioning groove 350 and the first positioning groove 340 are located on the same side of the third positioning plate 330, that is, both the second positioning groove 350 and the first positioning groove 340 are located on the left side of the third positioning plate 330, and the second positioning groove 350 is connected to the first positioning groove 340. Similarly, the second positioning groove 350 has a second slot 351 with its opening facing to the left, that is, the second slot 351 faces away from the third positioning plate 330.

[0080] Therefore, when the heat exchanger 200 moves toward the fixing buckle 300 and the first plate 211 of the side plate 210 is inserted into the first positioning groove 340, the second plates 212 of the two side plates 210 are respectively inserted into the second positioning grooves 350 through the second slots 351, so that the second positioning plate 323 abuts against the upper side of the second plate 212, thereby positioning the heat exchanger 200 in the vertical direction and preventing the heat exchanger 200 from shifting upward. That is, the side plate 210 is engaged with the fixing buckle 300. In this way, the fixing buckle 300 positions the heat exchanger 200 in the front-back direction, left-right direction, and vertical direction, which helps to further improve the installation position accuracy of the heat exchanger 200 and reduce the risk of damage to the heat exchanger 200. At the same time, it helps to further improve the alignment accuracy of the connecting hole 213 and the fixing hole 3122, making it easier for assembly personnel to insert fasteners and facilitating assembly.

[0081] When the heat exchanger 200 is positioned by the fixing clip 300, the second positioning plate 323 needs to abut against the second plate 212 of the side plate 210. Therefore, the opening of the second slot 351 is usually small. During the process of inserting the second plate 212 into the second positioning slot 350 through the second slot 351, the second plate 212 may get stuck at the left end of the second positioning plate 323, preventing it from being smoothly inserted into the second positioning slot 350. This requires the assembly personnel to readjust the position of the heat exchanger 200, sometimes requiring multiple adjustments, which affects assembly efficiency.

[0082] Therefore, referring to Figure 6 and Figure 7As shown, the second connecting portion 320 also includes a second guide plate 324, which is connected to the left end of the second positioning plate 323, i.e., the end of the second positioning plate 323 facing away from the third positioning plate 330. In this case, the second guide plate 324 is located above the second slot 351. The second guide plate 324 is arranged at an upward inclination, and the end of the second guide plate 324 facing away from the third positioning plate 330 is higher than the end of the second guide plate 324 closest to the third positioning plate 330. In other words, the left end of the second guide plate 324 is higher than the right end, and the second guide plate 324 extends upward at an inclination from the second positioning plate 323. Therefore, the distance between the left end of the second guide plate 324 and the bottom wall of the cavity 110 is relatively large and greater than the thickness of the second plate 212 of the side plate 210. During the insertion of the second plate 212 into the second positioning groove 350, the second plate 212 can be easily inserted into the space between the second guide plate 324 and the bottom wall of the cavity 110. As the second plate 212 moves further into the second positioning groove 350, the second guide plate 324 can accurately guide the second plate 212 to the second slot 351 of the second positioning groove 350, allowing the second plate 212 to be easily inserted into the second positioning groove 350 without jamming. This ensures that the second plate 212 can be smoothly inserted into the second positioning groove 350, eliminating the need for assembly personnel to repeatedly adjust the position of the heat exchanger 200, reducing assembly difficulty, facilitating assembly, and improving assembly efficiency.

[0083] Similarly, the opening of the first slot 341 is relatively small. During the process of inserting the first plate 211 into the first positioning slot 340 through the first slot 341, the first plate 211 may get stuck at the left end of the first positioning plate 312 or the left end of the second positioning plate 323 (or the second guide plate 324), which may prevent the first plate 211 from being inserted smoothly into the first positioning slot 340. This will require the assembly personnel to readjust the position of the heat exchanger 200, and may even require multiple adjustments, affecting the assembly efficiency.

[0084] Reference Figure 6 and Figure 7As shown, the first connecting portion 310 also includes a first guide plate 313. The first guide plate 313 is connected to the left end of the first positioning plate 312, that is, the first guide plate 313 is connected to the end of the first positioning plate 312 (or the first positioning groove 340) away from the third positioning plate 330. At this time, the first guide plate 313 is located behind the first groove 341, that is, the first guide plate 313 is located behind the second guide plate 324 and is spaced apart from the second guide plate 324. The first guide plate 313 is bent relative to the first positioning plate 312 in a direction away from the second connecting portion 320, that is, the first guide plate 313 is bent backward. Therefore, the space between the first guide plate 313 and the second guide plate 324 is relatively large. During the insertion of the first plate 211 into the first positioning groove 340, the first plate 211 can be easily inserted into the space between the first guide plate 313 and the second guide plate 324. As the first plate 211 moves further into the first positioning groove 340, the first guide plate 313 can accurately guide the first plate 211 to the opening of the first positioning groove 340, allowing the first plate 211 to be easily inserted into the first positioning groove 340 without jamming. This ensures that the first plate 211 can be smoothly inserted into the first positioning groove 340, eliminating the need for assembly personnel to repeatedly adjust the position of the heat exchanger 200, reducing assembly difficulty, facilitating assembly, and improving assembly efficiency.

[0085] Reference Figure 7 As shown, it can be understood that the second connecting portion 320 has a guide surface 325 on the side facing the first positioning groove 340, and the guide surface 325 is located at the end of the first positioning groove 340 away from the third positioning plate 330. Specifically, the guide surface 325 is disposed on the rear side of the second guide plate 324 and the rear side of the second positioning plate 323, and close to one end of the second guide plate 324. The guide surface 325 can be an inclined surface or an arc surface, and from right to left, the guide surface 325 gradually moves away from the first positioning plate 312 and the first guide plate 313. Therefore, the space between the first guide plate 313 and the second guide plate 324 can be further increased. During the insertion of the first plate 211 into the first positioning groove 340, the first plate 211 can be easily inserted into the space between the first guide plate 313 and the second guide plate 324. As the first plate 211 moves further into the first positioning groove 340, the first guide plate 313 and the guide surface 325 can accurately guide the first plate 211 to the opening of the first positioning groove 340, resulting in better guidance and higher accuracy. This allows the first plate 211 to be easily inserted into the first positioning groove 340, avoiding jamming. This ensures that the first plate 211 can be smoothly inserted into the first positioning groove 340, eliminating the need for assembly personnel to repeatedly adjust the position of the heat exchanger 200, reducing assembly difficulty, facilitating assembly, and improving assembly efficiency.

[0086] Of course, the guide surface 325 can be provided only on the rear side of the second guide plate 324, which will not be elaborated here.

[0087] When inserting the side plate 210 into the first positioning slot 340 and the second positioning slot 350, the assembler needs to adjust the position of the heat exchanger 200 in the front-rear direction so that the first plate 211 of the side plate 210 on the front and rear sides of the heat exchanger 200 can be aligned with the first positioning slots 340 of the two fixing clips 300, which is cumbersome. Furthermore, during the insertion process, the heat exchanger 200 may deflect in the horizontal direction, causing jamming and preventing successful assembly.

[0088] Therefore, referring to Figure 3 As shown, the chassis body 100 includes two guide bars 120. Both guide bars 120 are disposed on the bottom wall of the cavity 110 and correspondingly arranged on the side where the two fixing buckles 300 have the first slots 341. Specifically, the guide bars 120 protrude upwards from the bottom wall of the cavity 110. The guide bars 120 are located on the left side of the fixing buckles 300 and arranged in the left-right direction; that is, the guiding direction of the guide bars 120 is parallel to the left-right direction. The length direction of the first positioning groove 340 is also parallel to the left-right direction. Therefore, the guiding direction of the guide bars 120 is parallel to the length direction of the first positioning groove 340. The two guide bars 120 are parallel. Two guide bars 120 are located on opposite sides of the two first positioning grooves 340 in the front-rear direction. When the heat exchanger 200 is installed into the cavity 110, the second plates 212 of the two side plates 210 of the heat exchanger 200 can respectively abut against the opposite sides of the two guide bars 120 in the front-rear direction, and at this time, the first plates 211 of the two side plates 210 can be aligned with the two first positioning grooves 340 in the left-right direction. Therefore, the two guide bars 120 can limit the heat exchanger 200 in the front-rear direction, and the two guide bars 120 can accurately guide the heat exchanger 200 in the left-right direction, so that the heat exchanger 200 moves in the left-right direction and avoids deflection or deviation.

[0089] Therefore, during the process of installing the heat exchanger 200 onto the fixing clip 300, under the guidance of the guide bar 120, the heat exchanger 200 can move precisely toward the fixing clip 300, and the first plate 211 of the side plate 210 can be accurately inserted into the first positioning groove 340. At the same time, the second plate 212 of the side plate 210 can be accurately inserted into the second positioning groove 350, reducing alignment operations, lowering assembly difficulty, and avoiding jamming, thus effectively improving assembly efficiency.

[0090] Of course, in other embodiments, the two guide bars 120 can be respectively disposed on opposite sides of the two first positioning grooves 340 in the front-back direction. When the heat exchanger 200 is installed into the cavity 110, the second plates 212 of the two side plates 210 of the heat exchanger 200 can respectively abut against the opposite sides of the two guide bars 120 in the front-back direction, and at this time, the first plates 211 of the two side plates 210 can be respectively aligned with the two first positioning grooves 340 in the left-right direction. The two guide bars 120 can also limit the heat exchanger 200 in the front-back direction, and the two guide bars 120 can accurately guide the heat exchanger 200 in the left-right direction, so that the heat exchanger 200 moves in the left-right direction and avoids deflection or deviation.

[0091] Reference Figure 3 As shown, it can be understood that, for a chassis body 100 that is a sheet metal part, the guide strip 120 can be an upwardly protruding convex structure, obtained by punching and forming with a punch, that is, the guide strip 120 is integrally formed into the chassis body 100, which is convenient for processing. Alternatively, the guide strip 120 can be a long strip structure and welded to the bottom wall of the cavity 110. For a chassis body 100 that is a plastic part, the guide strip 120 is integrally formed with the chassis body 100 and is an upwardly protruding convex structure, which can be obtained by injection molding.

[0092] The fixing clips 300 are welded to the chassis body 100, specifically, the fixing clips 300 are welded to the bottom wall of the cavity 110. Since the two side plates 210 of the heat exchanger 200 need to be inserted into the two fixing clips 300 respectively, if the positions of the two fixing clips 300 are misaligned, even under the guidance of the guide strip 120, the side plates 210 cannot be inserted into the first positioning groove 340 and the second positioning groove 350 of the fixing clips 300, resulting in the inability to install the heat exchanger 200. The positions of the fixing clips 300 need to be readjusted and re-welded, affecting the assembly efficiency.

[0093] Therefore, referring to Figures 3 to 6As shown, the first connecting portion 310 also includes a fourth positioning plate 314, which is connected to the end of the first fixing plate 311 and bent downwards. For example, the fourth positioning plate 314 is connected to the left end of the first fixing plate 311 and is bent downwards and perpendicular to the first fixing plate 311. Correspondingly, the chassis body 100 is provided with a first positioning hole 130 corresponding to the fourth positioning plate 314, which is located at one end of the guide strip 120 in the left-right direction. In this embodiment, the first positioning hole 130 is located at the right end of the guide strip 120. When installing the fixing buckle 300, the fourth positioning plate 314 is inserted into the first positioning hole 130 until the first fixing plate 311 abuts against the bottom wall of the cavity 110, and then the first fixing plate 311 is welded to the bottom wall of the cavity 110. The positioning of the fixing buckle 300 can be achieved by the cooperation of the first positioning hole 130 and the fourth positioning plate 314, which restricts the degree of freedom of the fixing buckle 300 in the horizontal direction of the chassis body 100. This helps to improve the accuracy of the installation position of the fixing buckle 300, thereby ensuring that the two side plates 210 of the heat exchanger 200 can be inserted into the two fixing buckles 300 respectively, reducing the error rate and effectively improving the assembly efficiency.

[0094] Of course, the fourth positioning plate 314 can also be connected to the rear end, right end, etc. of the first fixing plate 311, which will not be elaborated here.

[0095] Reference Figures 3 to 6As shown, it can be understood that, similarly, the second connecting portion 320 also includes a fifth positioning plate 326 connected to the end of the second fixing plate 321 and bent downwards. For example, the fifth positioning plate 326 is connected to the left end of the second fixing plate 321, and the fifth positioning plate 326 is bent downwards and perpendicular to the second fixing plate 321. Correspondingly, the chassis body 100 is provided with a second positioning hole 140 corresponding to the fifth positioning plate 326. The second positioning hole 140 is located at one end of the guide strip 120 in the left-right direction, and the second positioning hole 140 and the first positioning hole 130 are located at the same end of the guide strip 120. In this embodiment, the second positioning hole 140 is also located at the right end of the guide strip 120. When installing the fixing clip 300, while the fourth positioning plate 314 is inserted into the first positioning hole 130, the fifth positioning plate 326 is inserted into the second positioning hole 140 until both the first fixing plate 311 and the second fixing plate 321 abut against the bottom wall of the cavity 110. Then, the first fixing plate 311 and the second fixing plate 321 are welded to the bottom wall of the cavity 110. Thus, the fixing clip 300 is positioned by the cooperation of the first positioning hole 130 and the fourth positioning plate 314, and the second positioning hole 140 and the fifth positioning plate 326, restricting the horizontal freedom of the fixing clip 300 on the chassis body 100. This further improves the accuracy of the fixing clip 300's installation position, ensuring that the two side plates 210 of the heat exchanger 200 can be inserted into the two fixing clips 300 respectively, reducing the error rate and effectively improving assembly efficiency.

[0096] Similarly, the fifth positioning plate 326 can also be connected to the front end, right end, etc. of the second fixing plate 321, which will not be described in detail here.

[0097] It is easy to understand that, since the guide strip 120 is located on one side of the first positioning hole 130 and the second positioning hole 140, the guide strip 120 can, to a certain extent, provide the assembler with an indication of the installation direction of the fixing buckle 300 in the left-right direction. That is to say, when installing the fixing buckle 300, simply align the first slot 341 with the side where the guide strip 120 is located for easy assembly.

[0098] Reference Figure 2 and Figure 6As shown, it can be understood that the first positioning plate 312 includes a fixed wing plate 3121, which is located above the third positioning plate 330 and extends from one side of the third positioning plate 330 to the other. A fixing hole 3122 is provided in the fixed wing plate 3121. Specifically, the fixed wing plate 3121 is the upper structure of the first positioning plate 312, extending from the left side to the right side of the third positioning plate 330, so that the fixed wing plate 3121 protrudes from the right side wall of the third positioning plate 330. Correspondingly, the first plate 211 of the side plate 210 includes a plate structure protruding to the right, and a connecting hole 213 is provided in this plate structure. Thus, the distance between the connecting hole 213 and the right side of the heat exchanger 200 is relatively large. After the heat exchanger 200 is installed in place, that is, the connecting hole 213 and the fixing hole 3122 are aligned, the right side of the heat exchanger 200 has a large operating space to pass fasteners through the connecting hole 213 and the fixing hole 3122, which is convenient for assembly personnel to operate.

[0099] Since the heat exchange tube 220 of the heat exchanger 200 protrudes from the first plate 211 of the side plate 210, in order to avoid interference between the heat exchange tube 220 and the first positioning plate 312, which would affect the installation of the heat exchanger 200, therefore, referring to Figure 1 and Figure 6 As shown, it can be understood that the upper end of the first positioning plate 312 is provided with a notch 3123, and both the upper and left sides of the notch 3123 are open. Therefore, when installing the heat exchanger 200, the heat exchanger 200 moves towards the fixing buckle 300, and the part of the heat exchange tube 220 protruding from the side plate 210 moves into the notch 3123. In other words, the notch 3123 can avoid the heat exchange tube 220, thereby preventing the heat exchange tube 220 from interfering with the first positioning plate 312, ensuring that the heat exchanger 200 can be installed in place, and improving reliability.

[0100] During the assembly of the fixing buckle 300 and the heat exchanger 200 to the chassis body 100, the cavity 110 is used as the initial positioning area. First, the fixing buckle 300 is installed on the bottom wall of the cavity 110, so that the fourth positioning plate 314 is inserted into the first positioning hole 130, and at the same time, the fifth positioning plate 326 is inserted into the second positioning hole 140, until the first fixing plate 311 and the second fixing plate 321 abut against the bottom wall of the cavity 110. At this time, it is necessary to ensure that the first slot 341 faces the side where the guide strip 120 is located. The first fixing plate 311 and the second fixing plate 321 are welded to the bottom wall of the cavity 110, thus completing the fixing of the fixing buckle 300 to the chassis body 100. Next, place the heat exchanger 200 at the two guide bars 120 of the cavity 110, so that the second plates 212 of the two side plates 210 of the heat exchanger 200 respectively abut against the opposite sides or opposite sides of the two guide bars 120. Under the limiting and guiding action of the two guide bars 120, the heat exchanger 200 is pushed and moved towards the fixing buckle 300. The first plate 211 of the side plate 210 passes through the guide surface 325 and the first guide plate 313 under the guidance of the guide surface 325. The first slot 341 is inserted into the first positioning slot 340. Simultaneously, the second plate 212 of the side plate 210, guided by the second guide plate 324, is inserted into the second positioning slot 350 through the second slot 351 until the side plate 210 abuts against the third positioning plate 330. At this point, the connecting hole 213 of the side plate 210 aligns with the fixing hole 3122 of the first positioning plate 312. Finally, fasteners are inserted into the connecting hole 213 and the fixing hole 3122 and locked to complete the assembly. Therefore, the assembly personnel can quickly position the heat exchanger 200 using the fixing buckle 300 without spending a lot of time and effort aligning the connecting hole 213 with the fixing hole 3122, effectively shortening the installation time and improving installation efficiency. Meanwhile, by positioning the heat exchanger 200 in the front-to-back direction using the first positioning plate 312, positioning the heat exchanger 200 in the left-to-right direction using the third positioning plate 330, and positioning the heat exchanger 200 in the up-down direction using the second positioning plate 323, the installation position accuracy of the heat exchanger 200 can be improved. This avoids the drawback of damage to the heat exchanger 200 due to deviations in its installation position, and effectively protects the heat exchanger 200.

[0101] The chassis assembly of the second aspect of this utility model includes a chassis body 100 and a fixing buckle 300 of the first aspect of this utility model. There are two fixing buckles 300. The two fixing buckles 300 are fixedly connected to the chassis body 100 and are arranged at intervals along the first direction. The first slot 341 and the second slot 351 of the two fixing buckles 300 both face one end of the second direction, that is, both face the left side, which will not be described in detail here.

[0102] Since the chassis assembly adopts all the technical solutions of the fixing buckle 300 in the above embodiments, it has at least all the beneficial effects brought about by the technical solutions in the above embodiments.

The heat exchanger 200 is installed on the chassis body 100, and the two side plates 210 of the heat exchanger 200 are respectively inserted into two fixing buckles 300. The side plates 210 and the fixing buckles 300 are fixed by fasteners so that the heat exchanger 200 is fixedly installed on the chassis body 100. Further details are omitted here.
