Description

Technical Field

[0001] This application relates to the field of HVAC installation technology, and in particular to a positioning device for installing an indoor unit of an HVAC system. Background Technology

[0002] Currently, HVAC systems are air conditioners that provide heating, ventilation, and air conditioning. HVAC systems can control air temperature and humidity, improving indoor comfort and are widely used in various locations. When installing indoor units, their positions need to be fixed to ensure operational stability.

[0003] In related technologies, multiple slots are provided on the back of the indoor unit. Multiple fasteners are then fixed to the wall according to the positions of these slots. These fasteners can be expansion bolts, steel nails, etc. During the installation of the HVAC indoor unit, the slots are aligned with the fasteners one by one. After the fasteners are inserted into the slots, the indoor unit is moved downwards to achieve a locking connection between the indoor unit and the fasteners, thus completing the installation.

[0004] Regarding the aforementioned technologies, when aligning the slots and fasteners one by one, the HVAC system needs to be repeatedly moved and adjusted under its own weight to find the position of the fasteners so that they can extend into the slots to achieve the snap-fit ​​and fixation between the indoor unit and the fasteners. The entire installation process is time-consuming and labor-intensive, resulting in low installation efficiency. Summary of the Invention

[0005] To improve the installation efficiency of air conditioning indoor units, this invention provides a positioning device for installing HVAC indoor units.

[0006] The positioning device for installing an indoor unit of a heating, ventilation, and air conditioning system provided by this invention adopts the following technical solution:

[0007] A positioning device for installing an indoor unit of a heating, ventilation, and air conditioning system includes a base plate connected to a wall and a fixing member semi-embedded in the base plate. A slot is provided on the back of the indoor unit body, including an insertion part for the fixing member to extend into and a engagement part for engaging the fixing member with the indoor unit body. The base plate is connected to a first positioning component for vertically positioning the indoor unit body and a second positioning component for horizontally positioning the indoor unit body. The base plate has a first sliding groove and a third sliding groove. The first positioning component is placed in the first sliding groove, and the second positioning component is placed in the third sliding groove. The base plate is connected to a first limiting component that restricts the first positioning component from entering the first sliding groove, and a second limiting component that restricts the second positioning component from entering the third sliding groove.

[0008] By adopting the above technical solution, when the indoor unit body needs to be installed, the indoor unit body is placed between the first positioning component and the second positioning component. At this time, the insertion part of the slot is directly opposite the fixing component. Then, the indoor unit body is pressed, and the first and second components are subjected to force from the indoor unit body. Both the second positioning component and the second component move. The movement of the first positioning component causes the first limiting component to move. After the first limiting component moves, it can no longer limit the first positioning component, and the first positioning component enters the first slide groove. At the same time, the second positioning component causes the second limiting component to move. After the second limiting component moves, it can no longer limit the second positioning component, and the second positioning component enters the second slide groove until the fixing component extends into the slot and engages. Then, the indoor unit body is moved again to allow the fixing component to enter the engaging part, thus fixing the indoor unit body and improving the installation efficiency of the air conditioner indoor unit body.

[0009] Preferably, at least two first positioning components are provided, with the at least two first positioning components respectively located on both sides of the base plate along its length direction, and at least two second positioning components are provided, with the at least two first positioning components respectively located at both ends of the base plate along its length direction.

[0010] By adopting the above technical solution, at least two first positioning components are respectively disposed at the top and bottom of the indoor unit body, limiting the top and bottom of the indoor unit body respectively. At least two second positioning components are respectively disposed on both sides of the indoor unit body, limiting the sides of the indoor unit body respectively. The cooperation of the first positioning components and the second positioning components ensures that the slot span of the indoor unit body is aligned with the fixing bracket, improving the installation efficiency of the air conditioner indoor unit body.

[0011] Preferably, the first positioning component includes a first positioning block and a first spring. One end of the first positioning block extends into the first sliding groove. The first positioning block is slidably connected to the base plate. The first spring is located in the first sliding groove. One end of the first spring is connected to the base plate and the other end is connected to the first positioning block. First positioning grooves are provided on the side walls of the first positioning blocks on both sides that are close to each other. The inner unit body is placed in the first positioning groove and abuts against the first positioning block. The bottom of the first positioning block is connected to the first limiting component.

[0012] By adopting the above technical solution, the indoor unit body is placed in the first positioning grooves located at the top and bottom of the indoor unit body, and the first positioning blocks located at the top and bottom of the indoor unit body together limit the position of the indoor unit body. Before installing the indoor unit body, the first positioning block protrudes from the base plate, and the first spring is stretched, and the first limiting component restricts the position of the first positioning block. When installing the indoor unit body, the indoor unit body is placed in the first positioning groove, and then the indoor unit body is pressed, causing the first positioning block to move towards the wall. The first positioning block drives the first limiting component to move until the fixing member is inserted into the extension part of the slot. At the same time, the bottom of the first positioning block disengages from the first limiting component, and the first spring pulls the first positioning block completely into the first sliding groove. Then the indoor unit body is moved so that the fixing member enters the snap-fit ​​part, fixing the position of the indoor unit body, thus improving the installation efficiency of the air conditioner indoor unit body.

[0013] Preferably, the base plate has a first movable cavity for placing the first limiting component. The first movable cavity is correspondingly arranged with and communicates with the first sliding groove. The first limiting component includes a first limiting block and a first compression spring. One end of the first limiting block extends into the first movable cavity and the other end extends into the first sliding groove. The first compression spring is located in the first movable cavity. One end of the first compression spring is connected to the base plate and the other end is connected to the first limiting block.

[0014] The first limiting block is slidably connected to the base plate, the bottom of the first positioning block slides against the top of the first limiting block, and the top of the first limiting block is inclined and tilted from one end near the first compression spring to the other end towards the wall.

[0015] By adopting the above technical solution, before installing the indoor unit body, the first compression spring is compressed, which keeps the first limiting block inserted into the first slide groove. The first limiting block abuts against the first positioning block, preventing the first positioning block from fully entering the first slide groove. When installing the indoor unit body, the first positioning block is pressed, causing the first limiting block to move towards the first compression spring until the first limiting block disengages from the bottom of the first positioning block, allowing the first positioning block to fully enter the first slide groove.

[0016] Preferably, the base plate has two second sliding grooves, and the base plate is connected to two fixing plates for further fixing the indoor unit body. The fixing plates are correspondingly arranged with the second sliding grooves and are located in the second sliding grooves. The base plate is connected to a control device for controlling whether the fixing plates abut against the back of the indoor unit body. The control device is connected to a first limiting block located on the same side of the base plate.

[0017] By adopting the above technical solution, when the protruding length of the fixing component is large, the first limiting component moves while driving the control component to move, and the control component makes the fixing plate abut against the indoor unit body, further restricting the position of the indoor unit body.

[0018] Preferably, the base plate has a second movable cavity, which communicates with the second sliding groove. The control component is located in the second movable cavity. The control device includes a control component for controlling the fixed plate to abut against the back of the indoor unit body and a drive component for driving the control component to move. The control component and the drive component are both connected to the base plate. The control component is connected to both the drive component and the fixed plate. The drive component is connected to the first limiting block.

[0019] By adopting the above technical solution, as the first limiting block gradually separates from the first positioning block, the first limiting block drives the drive component to move, the drive component drives the control component to move, and the control component drives the fixed plate to move, so that the fixed plate abuts against the indoor unit body.

[0020] Preferably, the control component includes a rotating shaft, a cam, and a connecting rod. Both ends of the rotating shaft are rotatably connected to the base plate. The rotating shaft is connected to the drive component, which drives the rotating shaft to rotate. The cam is sleeved on the rotating shaft and fixedly connected to it. The end wall of the cam abuts against the fixed plate. A sliding groove with the same movement trajectory as the end wall of the cam is formed on the cam. One end of the connecting rod extends into the sliding groove, and the other end is fixedly connected to the fixed plate. The connecting rod is slidably connected to the cam.

[0021] By adopting the above technical solution, the drive component drives the rotating shaft to rotate, the rotating shaft drives the cam to rotate, and the connecting rod is in the sliding groove. Because the cam rotates and the cam abuts against the fixed plate, the fixed plate will extend out of the second sliding groove or completely enter the second sliding groove.

[0022] Preferably, the second movable cavity is connected to the first movable cavity located on the same side of the base plate. The driving assembly includes a gear and a rack. The gear is sleeved on the rotating shaft and fixedly connected to the rotating shaft. The rack meshes with the gear, and one end of the rack is fixedly connected to the first limiting block.

[0023] By adopting the above technical solution, when the first limiting block moves, the first limiting block drives the rack to move, the rack drives the gear to move, and the gear drives the rotating shaft to rotate.

[0024] Preferably, the second positioning component includes a second positioning block and a second spring second positioning block. One end of the second positioning block extends into the third sliding groove. The second positioning block is slidably connected to the base plate. The second spring is located in the third sliding groove. One end of the second spring is connected to the base plate and the other end is connected to the second positioning block. Second positioning grooves are provided on the side walls of the two second positioning blocks that are close to each other. The inner unit body is placed in the second positioning groove and abuts against the second positioning block. The bottom of the second positioning block is connected to the second limiting component.

[0025] By adopting the above technical solution, the indoor unit body is placed in the second positioning grooves located at the top and bottom of the indoor unit body. The second positioning blocks located at the top and bottom of the indoor unit body together limit the position of the indoor unit body. Before installing the indoor unit body, the second positioning block protrudes from the base plate, and the second spring is stretched, with the second limiting component restricting the position of the second positioning block. When installing the indoor unit body, the indoor unit body is placed in the second positioning groove, and then the indoor unit body is pressed, causing the second positioning block to move towards the wall. The second positioning block drives the second limiting component to move until the fixing member is inserted into the extension part of the slot. At the same time, the bottom of the second positioning block disengages from the second limiting component, and the second spring pulls the second positioning block completely into the second sliding groove. Then, the indoor unit body is moved so that the fixing member enters the snap-fit ​​part, fixing the position of the indoor unit body and improving the installation efficiency of the air conditioner indoor unit body.

[0026] Preferably, the base plate has a third movable cavity for placing the second limiting component. The third movable cavity is connected to the third sliding groove. The second limiting component includes a second limiting block and a second compression spring. One end of the second limiting block extends into the third movable cavity and is slidably connected to the base plate. The second compression spring is located in the third movable cavity. One end of the second compression spring is connected to the base plate and the other end is connected to the second limiting block.

[0027] The second limiting block extends into the third sliding groove, the bottom of the second positioning block abuts against the top of the second limiting block, and the top of the second limiting block is inclined and tilted from one end near the second compression spring to the other end towards the wall.

[0028] By adopting the above technical solution, before installing the indoor unit body, the second compression spring is compressed, causing the second limiting block to extend into the second slide groove. The second limiting block abuts against the second positioning block, preventing the second positioning block from fully entering the second slide groove. When installing the indoor unit body, the second positioning block is pressed, causing the second limiting block to move towards the second compression spring until the second limiting block disengages from the bottom of the second positioning block, allowing the second positioning block to fully enter the second slide groove.

[0029] In summary, the present invention has the following beneficial effects:

[0030] 1. By limiting the indoor unit body with the first positioning block and the second positioning block, the slot and the fastener are aligned, and the fastener can be quickly inserted into the slot, which improves the installation efficiency of the indoor unit body.

[0031] 2. When the first positioning block is retracted into the first sliding groove, the first limiting block slides into the first movable cavity. The first limiting block drives the rack to move, the rack drives the gear to rotate, the gear drives the rotating shaft to rotate, the rotating shaft drives the cam to rotate, and the cam rotation causes the connecting rod to move in the sliding groove and causes the fixing plate to protrude from the bottom plate. The fixing plate further restricts the position of the indoor unit body, making the indoor unit body installed stably. The fixing plate also leaves space between the indoor unit body and the bottom plate, which can be used for heat dissipation of the indoor unit body. Attached Figure Description

[0042] The present invention will be further described in detail below with reference to the accompanying drawings.

[0043] A positioning device for installing an indoor unit of a heating, ventilation, and air conditioning system, referring to Figure 1 and Figure 2 The unit includes a base plate 1, a fastener 2, a first positioning component 4, and a second positioning component 8. The base plate 1 is fixedly connected to the wall. The fastener 2 is partially embedded in the base plate 1. The first positioning component 4 is connected to the base plate 1 and is used to position the indoor unit body 3 in the vertical direction. The second positioning component 8 is connected to the base plate 1 and is used to position the indoor unit body 3 in the horizontal direction. A slot 31 is provided on the back of the indoor unit body 3. The first positioning component 4 and the second positioning component 8 cooperate to align the slot 31 with the fastener 2, thereby improving the installation efficiency of the indoor unit body 3.

[0044] Reference Figure 1 and Figure 2 At least one fixing member 2 is provided. In this embodiment, four fixing members 2 are provided. The four fixing members 2 are divided into two groups. The two groups of fixing members 2 are distributed in the vertical direction. The fixing members 2 in the same group are distributed along the length direction of the base plate 1. The fixing member 2 includes a connecting part and a fixing part. The connecting part is fixedly connected to the base plate 1, and the fixing part is fixedly connected to the connecting part. Four slots 31 are provided corresponding to the fixing members 2. The slots 31 include an insertion part and a snap-fit ​​part. The insertion part matches the fixing part, the snap-fit ​​part matches the connecting part, and the insertion part communicates with the snap-fit ​​part.

[0045] Reference Figure 1 and Figure 3Four first positioning components 4 are provided, symmetrically arranged on both sides of the base plate 1 along its length. At least two first sliding grooves 11 are provided on the base plate 1, each corresponding to one of the four first positioning components 4. The four sets of first positioning components 4 cooperate to limit the top and bottom of the indoor unit body 3.

[0046] Reference Figure 4 The first positioning component 4 includes a first positioning block 41 and a first spring 42. One end of the first positioning block 41 extends into the first sliding groove 11 and is slidably connected to the base plate 1. First positioning grooves 411 are formed on the side walls of the first positioning blocks 41 located on both sides of the base plate 1 that are close to each other. The first spring 42 is located in the first sliding groove 11. One end of the first spring 42 is fixedly connected to the base plate 1, and the other end is fixedly connected to the first positioning block 41.

[0047] When installing the indoor unit body 3, place the indoor unit body 3 in the first positioning groove 411, then press the indoor unit body 3 to move the first positioning block 41 towards the wall until the fixing member 2 is inserted into the extension part of the slot 31. The first spring 42 pulls the first positioning block 41 into the first sliding groove 11, and then moves the indoor unit body 3 to make the fixing member 2 enter the snap-fit ​​part, thereby fixing the position of the indoor unit body 3 and improving the installation efficiency of the air conditioner indoor unit body 3.

[0048] Reference Figure 4 The base plate 1 has four first movable cavities 14, each corresponding to a first sliding groove 11, and the first movable cavities 14 are connected to the first sliding groove 11. The base plate 1 is connected to four first limiting components 5, each corresponding to a first positioning block 41, and the first limiting components 5 are located within the first movable cavities 14.

[0049] Reference Figure 4 The first limiting component 5 includes a first limiting block 51 and a first compression spring 52. One end of the first limiting block 51 extends into the first movable cavity 14, and the other end extends into the first sliding groove 11. The first limiting block 51 matches the first movable cavity 14 and is slidably connected to the base plate 1. The first compression spring 52 is located in the first movable cavity 14. Multiple first compression springs 52 are provided. One end of the first compression spring 52 is fixedly connected to the base plate 1, and the other end is fixedly connected to the first limiting block 51.

[0050] Reference Figure 4 The bottom of the first positioning block 41 is fixedly connected to the first roller 412, the top surface of the first limiting block 51 slides against the first roller 412, the top surface of the first limiting block 51 is inclined, and it is inclined from one end near the first compression spring 52 to the other end towards the wall.

[0051] Before installing the indoor unit body 3, the first compression spring 52 is compressed, causing the first limiting block 51 to extend into the first slide groove 11. The first limiting block 51 restricts the position of the first positioning block 41. When installing the indoor unit body 3, the first positioning block 41 is pressed, causing the first limiting block 51 to move closer to the first compression spring 52 until the first limiting block 51 disengages from its bottom, allowing the first positioning block 41 to fully enter the first slide groove 11. The rollers reduce wear between the first positioning block 41 and the first limiting block 51, increasing their service life.

[0052] Reference Figure 4 The base plate 1 has two second sliding grooves 12. A fixing plate 6 is installed within each second sliding groove 12, and the fixing plate 6 slides against the base plate 1. One fixing plate 6 is fitted onto multiple fixing members 2 within the same group, and the connection between the fixing plate 6 and the fixing members 2 is slidably connected. The fixing plate 6 extends out of the base plate 1 and abuts against the indoor unit body 3, further restricting the position of the indoor unit body 3, and the reserved space allows for heat dissipation of the indoor unit body 3.

[0053] Reference Figure 4 and Figure 5 The base plate 1 is connected to a control device 7. Two control devices 7 are provided, each corresponding to a fixed plate 6, and are connected to the fixed plate 6. Two second movable cavities 15 are provided on the base plate 1, and the two control devices 7 are respectively located within the two second movable cavities 15. The second movable cavities 15 communicate with multiple first movable cavities 14 and with the second sliding groove 12.

[0054] Reference Figure 5 and Figure 6 The control device 7 includes a drive assembly 71 and a control assembly 72. Four drive assemblies 71 are arranged in two groups. Each drive assembly 71 in the same group corresponds to two first limiting blocks 51 located on the same side of the base plate 1 along its length. Each drive assembly 71 includes a gear 711 and a rack 712. The gear 711 is sleeved on and fixedly connected to the rotating shaft 721. The rack 712 meshes with the gear 711, and one end of the rack 712 is fixedly connected to the first limiting block 51. The rack 712 is slidably connected to the base plate 1.

[0055] When the first limit block 51 moves, the first limit block 51 drives the rack 712 to move, the rack 712 drives the gear 711 to move, and the gear 711 drives the rotating shaft 721 to rotate.

[0056] Reference Figure 5 and Figure 7The control component 72 includes a rotating shaft 721, a cam 722, and a connecting rod 723. The length direction of the rotating shaft 721 is parallel to the length direction of the base plate 1. At least one cam 722 is provided, which is sleeved on the rotating shaft 721 and fixedly connected to it. A sliding groove 7221 is formed on the cam 722, which matches one end of the connecting rod 723. One end of the connecting rod 723 extends into the sliding groove 7221, and the other end is fixedly connected to the fixing plate 6. The connecting rod 723 is slidably connected to the cam 722, and the cam 722 abuts against the fixing plate 6.

[0057] As the first limiting block 51 gradually disengages from the first positioning block 41, the first limiting block 51 drives the drive assembly 71 to move. The drive assembly 71 drives the rotating shaft 721 to rotate. The rotating shaft 721 drives the cam 722 to rotate. The connecting rod 723 is in the sliding groove 7221. Because the cam 722 rotates and abuts against the fixed plate 6, the fixed plate 6 will extend out of the second sliding groove 12 or completely enter the second sliding groove 12.

[0058] Reference Figure 8 There are two second positioning components 8, which are symmetrically arranged at both ends of the base plate 1 along its length. Two third sliding grooves 13 are provided on the base plate 1, each corresponding to one of the two second positioning components 8. The two second positioning components 8 respectively limit the movement of both ends of the indoor unit body 3.

[0059] Reference Figure 8 The second positioning component 8 includes a second positioning block 81 and a second spring 82. One end of the second positioning block 81 extends into the third sliding groove 13 and is slidably connected to the base plate 1. Second positioning grooves 811 are formed on the side walls of the second positioning blocks 81 located on both sides of the base plate 1 that are close to each other. The second spring 82 is located in the third sliding groove 13. One end of the second spring 82 is fixedly connected to the base plate 1, and the other end is fixedly connected to the second positioning block 81.

[0060] Before installing the indoor unit body 3, the second positioning block 81 protrudes from the base plate 1, and the second spring 82 is stretched, with the second limiting component 9 restricting the position of the second positioning block 81. When installing the indoor unit body 3, the indoor unit body 3 is placed in the second positioning groove 811 and pressed down, causing the second positioning block 81 to move towards the wall. The second positioning block 81 is fully pulled into the second sliding groove 12 by the second spring 82. Then, the indoor unit body 3 is moved so that the fixing part 2 enters the snap-fit ​​part, fixing the position of the indoor unit body 3 and improving the installation efficiency of the air conditioner indoor unit body 3.

[0061] Reference Figure 8The base plate 1 has two third movable cavities 16, which correspond one-to-one with the third sliding grooves 13 and are connected to each other. The base plate 1 is connected to two second limiting components 9, which correspond one-to-one with the second positioning blocks 81 and are located within the third movable cavities 16.

[0062] Reference Figure 8 The second limiting component 9 includes a second limiting block 91 and a second compression spring 92. One end of the second limiting block 91 extends into the third movable cavity 16, and the other end extends into the third sliding groove 13. The second limiting block 91 matches the third movable cavity 16 and is slidably connected to the base plate 1. The second compression spring 92 is located in the third movable cavity 16. Multiple second compression springs 92 are provided. One end of the second compression spring 92 is fixedly connected to the base plate 1, and the other end is fixedly connected to the second limiting block 91.

[0063] Reference Figure 8 The bottom of the second positioning block 81 is fixedly connected to the second roller 812, the top surface of the second limiting block 91 slides against the second roller 812, the top surface of the second limiting block 91 is inclined, and it is inclined from one end near the second compression spring 92 towards the wall.

[0064] Before installing the indoor unit body 3, the second compression spring 92 is compressed, which causes the second limiting block 91 to restrict the second positioning block 81 from fully entering the second slide groove 12. When installing the indoor unit body 3, the second positioning block 81 is pressed, which causes the second limiting block 91 to move closer to the second compression spring 92 until the second limiting block 91 disengages from the bottom of the second positioning block 81, allowing the second positioning block 81 to fully enter the second slide groove 12.

[0065] The working principle of this application is as follows: When installing the indoor unit body 3, the indoor unit body 3 is placed in the first positioning groove 411 and the second positioning groove 811, so that the extension part of the slot 31 is aligned with the fixing member 2. Then, the indoor unit body 3 is pressed, and the first positioning block 41 and the second positioning block 81 move towards the wall. The fixing member 2 extends into the extension part of the slot 31, which improves the installation efficiency of the indoor unit body 3.

[0066] When the fixing member 2 extends into the insertion part of the slot 31, the first roller 412 disengages from the first limiting block 51, the second roller 812 disengages from the second limiting block 91, the first positioning block 41 is pulled back into the first sliding groove 11 by the first spring 42, the second positioning block 81 is pulled back into the third sliding groove 13 by the second spring 82, the first limiting block 51 retracts into the first movable cavity 14, the second limiting block 91 retracts into the third movable cavity 16, the movement of the first limiting block 51 drives the rack 712 to move, the gear 711 drives the rotating shaft 721 to rotate, the rotating shaft 721 drives the cam 722 to rotate, the rotation of the cam 722 causes the connecting rod 723 to move in the sliding groove 7221, and causes the fixing plate 6 to protrude from the bottom plate 1, the fixing plate 6 abuts against the indoor unit body 3, fixing the position of the indoor unit body 3, improving the installation speed of the indoor unit body 3, and at the same time improving the stability of the indoor unit body 3 installation.
