With the development of economy, people's pursuit of travel and tourism quality of life is increasing day by day, and RVs have gradually become the permanent living place for residents to travel. Therefore, people have put forward higher environmental requirements for RVs, and RV air conditioners have come into being. RV air conditioners, as the main electrical equipment to improve the internal environment of RVs, have gradually become the standard of modern RVs.

RV air conditioners are generally installed on the top 2000 of the vehicle, so RV air conditioners are also called roof-mounted air conditioners. The roof-mounted air conditioners are connected downward to the internal environment of the RV through the installation port 2100 on the top 2000 of the vehicle to provide air conditioning for it. Since the roof-mounted air conditioner is installed on the RV, it needs to face the continuous vibration of the RV during driving, and the assembly reliability of the roof-mounted air conditioner is particularly important. However, it is difficult to align the traditional roof-mounted air conditioner during installation in the RV. The installer needs to go back and forth between the top 2000 of the vehicle and the interior of the vehicle for multiple adjustments to achieve alignment installation. In addition, the installation accuracy of the roof-mounted air conditioner is difficult to grasp, which affects the connection reliability of the roof-mounted air conditioner, resulting in low installation efficiency and installation accuracy of the roof-mounted air conditioner.

It should be noted that the front and back and up and down directions described in the embodiments of the present disclosure are based on the air-conditioning body 100, and the direction relationship marked in Figures 1 and 2 is used as a reference. The front and back and up and down directions of the roof-mounted air conditioner correspond one-to-one to the direction of the RV.

As shown in FIG. 1 and FIG. 2 , in order to solve the installation problem of the ceiling-mounted air conditioner, the ceiling-mounted air conditioner of an embodiment of the present disclosure includes an air conditioner body 100, a support plate 200, a top plate 300 and a sealing ring 400. The air conditioner body 100 includes a chassis 110 and a top cover 120, and also includes an inner air duct assembly 130 with an indoor heat exchanger 131, an outer air duct assembly 140 with an outdoor heat exchanger 141, and a compressor and an electric control box assembly. The chassis 110 is the main load-bearing component of the air conditioner body 100, and the inner air duct assembly 130, the outer air duct assembly 140, the compressor and the electric control box assembly are directly or indirectly mounted on the chassis 110. The support plate 200 and the top plate 300 are respectively arranged on the outer side and the inner side of the top 2000 of the vehicle, the top plate 300 is located below the support plate 200, and the support plate 200 is fixedly connected to the bottom of the chassis 110. The support plate 200 can be mounted on the chassis 110 by screws or the like. 4 and 6 , the top plate 300 can be fixedly connected to the chassis 110 by bolts 500, and the chassis 110 can be embedded with metal nuts 112 by injection molding so as to match the bolts 500, thereby clamping the air-conditioning body 100 and the top plate 300 to the top 2000 of the vehicle, thereby achieving a stable and reliable connection between the roof-mounted air conditioner and the RV.

As shown in Figure 3, it can be understood that the chassis 110 is provided with positioning ribs 111, which are arranged at the bottom of the chassis 110 and protrude outward. A plurality of positioning ribs 111 can be provided, and the plurality of limiting ribs are positioned and cooperated with the peripheral edge of the support plate 200, thereby facilitating the determination of the installation position of the support plate 200 and achieving a stable connection between the support plate 200 and the chassis 110.

2, 7 and 8, it can be understood that in order to enable the air inlet and the air outlet of the air conditioner body 100 to communicate with the internal environment of the RV, the support plate 200 is provided with a first communication hole 210, and the top plate 300 is provided with a second communication hole 310. When the roof-mounted air conditioner is installed on the top 2000 of the vehicle, the second communication hole 310 is connected to the first communication hole 210 through the mounting port 2100. In order to prevent the air inlet and the air outlet of the air conditioner body 100 from being blown away, the top plate 300 is provided with a partition 320, and the partition 320 separates the mounting port 2100 into an air inlet channel and an air outlet channel.

As shown in FIG. 1 and FIG. 2 , it can be understood that when the roof-mounted air conditioner is installed on the top 2000 of the vehicle, the sealing ring 400 can be fixed to the outer side of the top 2000 of the vehicle by gluing or other methods, and the sealing ring 400 is arranged around the periphery of the mounting opening 2100, so as to achieve the alignment installation with the mounting opening 2100. As shown in FIG. 4 , FIG. 5 and FIG. 7 , the end of the support plate 200 facing the mounting opening 2100 abuts against the sealing ring 400, and the support plate 200 is further provided with an outer skirt 220, which is located at the end of the support plate 200 facing downward, that is, the end facing the mounting opening 2100, and the outer skirt 220 is arranged along the outer periphery of the support plate 200. The outer skirt 220 can be integrally manufactured and formed with the support plate 200, that is, formed by folding the outer periphery of the support plate 200 downward; or fixedly connected to the support plate 200 by welding or other methods. In addition, the provision of the outer skirt 220 can also enhance the structural strength of the support plate 200, thereby improving the installation stability of the ceiling-mounted air conditioner.

It is understandable that the support plate 200 can be positioned and matched with the outer wall of the sealing ring 400 through the outer skirt 220. Therefore, after the installer aligns the sealing ring 400 with the installation opening 2100, the air conditioner body 100 can be quickly and accurately aligned with the installation opening 2100 through the positioning relationship between the outer skirt 220 and the sealing ring 400, avoiding the installer to repeatedly go back and forth between the top 2000 of the vehicle and the inside of the vehicle for adjustment, thereby improving the installation efficiency and installation accuracy, and improving the safety of the installer. In addition, the positioning and matching of the outer skirt 220 and the sealing ring 400 can effectively prevent the installer from shaking or shifting the air conditioner body 100 during the installation of the top plate 300, making it more efficient and convenient for the installer to tighten the bolts 500, while preventing the air conditioner body 100 from slipping and being damaged, thereby improving the safety of the installation.

As shown in FIG. 2 and FIG. 5 , it can be understood that the top plate 300 and the bottom plate 110 can be fixed by a plurality of bolts 500. The number of bolts 500 can be selected according to the size of the air conditioner body 100 and the size of the mounting opening 2100, such as four, six or more bolts, which are not specifically limited here. The plurality of bolts 500 are arranged close to the inner wall of the mounting opening 2100 and are arranged at intervals along the circumference of the mounting opening 2100, thereby reducing the influence of the bolts 500 on the air inlet and outlet of the top-mounted air conditioner.

Moreover, compared with the installation structure of a traditional ceiling-mounted air conditioner, the installation of the ceiling-mounted air conditioner of the embodiment of the present disclosure involves fewer parts and fewer installation operation steps, which is conducive to improving installation efficiency.

As shown in FIG. 5 , it can be understood that the sealing ring 400 is arranged between the support plate 200 and the top 2000 of the vehicle, and plays an effective sealing role, so that the air inlet and the air outlet of the air conditioner main body 100 are sealed and communicated with the internal environment of the RV through the installation port 2100. The sealing ring 400 of the disclosed embodiment is made of elastic material with compressible properties, such as sponge, pearl cotton, EVA (also known as ethylene-vinyl acetate copolymer), etc., so the sealing ring 400 can also achieve a better buffering effect, buffer the vibration between the air conditioner main body 100 and the top 2000 of the vehicle, effectively reduce the vibration generated by the RV during bumpy driving to the air conditioner main body 100, reduce the shaking of the air conditioner main body 100, and improve the installation stability of the roof-mounted air conditioner and the RV.

As shown in FIG. 1 and FIG. 3 , it can be understood that the roof-mounted air conditioner further includes a shock-absorbing pad 600, which can play a buffering role. When the roof-mounted air conditioner is installed on the top 2000 of the vehicle, the shock-absorbing pad 600 is arranged between the air conditioner body 100 and the top 2000 of the vehicle, and the shock-absorbing pad 600 and the sealing ring 400 are arranged at intervals along the front and rear direction of the air conditioner body 100. It can be understood that the shock-absorbing pad 600 is arranged at the rear of the chassis 110, and the sealing ring 400 is arranged at the front of the chassis 110, so that the force of the air conditioner body 100 is more uniform, further reducing the vibration generated by the RV during bumpy driving to the air conditioner body 100, reducing the shaking of the air conditioner body 100, and improving the installation stability of the roof-mounted air conditioner and the RV.

As shown in Fig. 8 and Fig. 9, it can be understood that the top plate 300 includes a positioning boss 330 and a mounting edge 340, and the mounting edge 340 is arranged around the periphery of the positioning boss 330. The top plate 300 can be formed by integral stamping, so that the strength of the positioning boss 330 and the mounting edge 340 is higher. As shown in Fig. 5, the positioning boss 330 protrudes toward the mounting opening 2100, and the positioning boss 330 is positioned and matched with the inner wall of the mounting opening 2100. It can be understood that the positioning boss 330 includes an end plate 331 and a side plate 332, and the end plate 331 is located at one end of the positioning boss 330 facing the support plate 200, and the side plate 332 is arranged around the end plate 331 and connected to the mounting edge 340. The side plate 332 abuts against the inner wall of the mounting opening 2100 to limit the displacement of the top plate 300 in the horizontal direction on the top 2000 of the vehicle, and the mounting edge 340 abuts against the inner side of the top 2000 of the vehicle to limit the displacement of the top plate 300 in the thickness direction of the top 2000 of the vehicle, thereby achieving accurate alignment of the top plate 300. The disclosed embodiment can effectively prevent the top plate 300 from shaking inside the mounting opening 2100, prevent the air conditioner body 100 from shaking accordingly, improve the installation accuracy of the top plate 300, and facilitate the installer to tighten the bolts 500 between the top plate 300 and the chassis 110.

As shown in FIG8 , it can be understood that the end of the positioning boss 330 facing the support plate 200 is provided with an end plate 331, the second communication hole 310 is opened in the end plate 331, and the end plate 331 is provided with a fixing hole 333, and the fixing hole 333 is used for the bolt 500 to pass through and be fixed to the end plate 331. It can be understood that the fixing hole 333 is provided on the periphery of the second communication hole 310, so as to avoid the bolt 500 passing through the fixing hole 333 and affecting the air inlet channel and the air outlet channel.

In the disclosed embodiment, the cross section of the mounting opening 2100 is rectangular, and the positioning boss 330 matches the shape of the mounting opening 2100 and is rectangular. It should be noted that there are four fixing holes 333, which are respectively located at the four corners of the end plate 331, that is, located on one side of the inner wall close to the mounting opening 2100. Correspondingly, there are four bolts 500, which are respectively fixed to the four fixing holes 333, and the four bolts 500 are fixedly connected to the chassis 110, thereby realizing a stable connection between the top plate 300 and the chassis 110, and further realizing a stable connection between the roof-mounted air conditioner and the top 2000 of the vehicle. It should be noted that the lower end of the mounting opening 2100 is closely attached to the mounting edge 340. Since the positioning boss 330 and the mounting edge 340 are integrally stamped, the mounting edge 340 transmits the locking force on the positioning boss 330 when the bolt 500 is tightened upward, so that the mounting edge 340 can lock the vehicle top 2000 upward, evenly distribute the locking force of the four bolts 500, and form a surface contact clamp with the vehicle top 2000, making the installation more stable and reliable.

7 , it can be understood that the outer skirt 220 is formed by folding the outer peripheral edge of the support plate 200 downward, so that the outer skirt 220 has higher strength, and the outer skirt 220 can also enhance the structural strength of the support plate 200, thereby improving the installation stability of the ceiling-mounted air conditioner.

Referring to FIG. 10 , another embodiment of the roof-mounted air conditioner disclosed herein, in order to facilitate the installation of the top plate 300 by the installer, the top plate 300 of one embodiment of the disclosure adopts a design that can be pre-fixed with the support plate 200, for example, by movable buckles, clips, magnets, etc., so that the top plate 300 and the support plate 200 are pre-fixed and connected. Therefore, after the air conditioner body 100 is positioned by the support plate 200, the installer can pre-fix the top plate 300 with the support plate 200 in the RV, and can directly tighten the bolts 500 by operating with both hands to achieve the fastening of the top plate 300, without the need for one person to hold the top plate 300 with one hand and tighten the bolts 500 with the other hand, nor the need for one person to hold the top plate 300 and another person to tighten the bolts 500, thereby improving the installation efficiency and reducing the installation cost.

As shown in FIG. 10 , as one embodiment, the support plate 200 is provided with an inner skirt 230, and the inner skirt 230 is located at the downward end of the support plate 200, that is, the end facing the installation port 2100. The mechanism for achieving pre-fixation can be an adsorption member 350, and the adsorption member 350 can be provided on the top plate 300, or on the inner skirt 230, or on both the top plate 300 and the inner skirt 230. The adsorption member 350 adsorbs and connects the top plate 300 and the inner skirt 230, thereby achieving pre-fixation between the two. For example, the adsorption member 350 can be a magnet, or can be adhesive, or other materials that can achieve adsorption of the top plate 300 and the inner skirt 230.

As shown in FIG. 10 , it can be understood that, in order to facilitate production and manufacturing, the adsorption member 350 of the embodiment of the present disclosure is a magnet, and the adsorption member 350 is arranged on the top plate 300. The inner skirt 230 is made of metal material, and the adsorption member 350 is adsorbed and connected to the inner skirt 230, thereby realizing the pre-fixation of the top plate 300, and its production cost is lower and the structure is more stable. There can be multiple adsorption members 350, and multiple adsorption members 350 are arranged at intervals along the circumference of the top plate 300. Each adsorption member 350 is fixed to the corresponding position of the top plate 300, so that the pre-fixed connection of the top plate 300 is more stable, and the risk of the top plate 300 falling off is effectively prevented.

It is understood that, as another embodiment, the top plate 300 is provided with a first fastener, and the support plate 200 is provided with a second fastener. It is understood that the first fastener can be one of the matching active buckle and buckle ring, and correspondingly, the second fastener can be the other of the matching active buckle and buckle ring. After the active buckle is connected to the buckle ring, the top plate 300 and the support plate 200 can be pre-fixed, so that the installer can directly tighten the bolts 500 by both hands to achieve the fastening of the top plate 300, thereby improving the installation efficiency.

It is understandable that, as another embodiment, the top plate 300 is provided with a first adhesive member, and the first adhesive member is used to bond the vehicle top 2000. It is understandable that the first adhesive member is set at a suitable position of the top plate 300. When the installer installs the top plate 300, the top plate 300 can be pre-fixed to the inner side of the vehicle top 2000 or the inner wall of the installation opening 2100 by the first adhesive member, so that the top plate 300 and the support plate 200 are pre-fixed, so that the installer can directly tighten the bolts 500 by both hands to achieve the fastening of the top plate 300, thereby improving the installation efficiency.

It is understood that, as another embodiment, the top plate 300 or the inner skirt 230 is provided with a second adhesive, or both the top plate 300 and the inner skirt 230 are provided with a second adhesive. When the roof-mounted air conditioner is installed on the top 2000 of the vehicle, the second adhesive is used to bond the top plate 300 and the inner skirt 230. It is understood that the second adhesive can be a material such as a double-sided adhesive. The second adhesive is set at a suitable position of the top plate 300 and/or the inner skirt. When the installer installs the top plate 300, the top plate 300 and the inner skirt 230 can be bonded by the second adhesive to achieve pre-fixation, so that the installer can directly tighten the bolts 500 by both hands to achieve the fastening of the top plate 300, thereby improving the installation efficiency.

As shown in FIG. 10 , it can be understood that when the bolt 500 is in a loose state, that is, when the bolt 500 is not tightened on the top plate 300, the gap between the outer skirt 220 and the upper end surface of the installation opening 2100 is D; as shown in FIG. 11 , it can be understood that when the bolt 500 is in a locked state, that is, after the top-mounted air conditioner and the vehicle top 2000 are installed, the gap between the outer skirt 220 and the upper end surface of the installation opening 2100 is H, which satisfies: 0＜H≤0.5D. It should be noted that when the above parameter range is met, the sealing ring 400 can achieve a certain compression after the bolt 500 is tightened, thereby forming a sealing fit with the vehicle top 2000, and at the same time, the cushioning and vibration reduction effect of the sealing ring 400 is also guaranteed.

Referring to FIG. 1 and FIG. 12 , in order to solve the installation problem of the ceiling-mounted air conditioner, a ceiling-mounted air conditioner according to another embodiment of the present disclosure includes an air conditioner body 100, a support plate 200 and a top plate 300.

In order to prevent the air inlet and the air outlet of the air conditioner body 100 from blowing, the top plate 300 is provided with a partition 320, and the partition 320 separates the mounting port 2100 into an air inlet channel and an air outlet channel.

As shown in Figures 12, 14 and 15, it can be understood that the support plate 200 is provided with an inner skirt 230, and the inner skirt 230 is located at the end of the support plate 200 facing downward, that is, the end facing the installation port 2100. The inner skirt 230 can be arranged along the periphery of the first communication hole 210, so as to maximize the cross-sectional area of the first communication hole 210. The inner skirt 230 can be formed by stamping the support plate 200, so that the inner skirt 230 is formed at the edge of the first communication hole 210. The inner skirt 230 can also be fixed to the support plate 200 by welding or the like. It should be noted that when the roof-mounted air conditioner is installed on the top 2000 of the vehicle, the inner skirt 230 is positioned and matched with the inner wall of the installation port 2100, for example, the inner skirt 230 abuts against the inner wall of the installation port 2100, so that the installation port 2100 can limit the displacement of the support plate 200 in the horizontal direction. In one embodiment of the present disclosure, the cross-section of the mounting opening 2100 is rectangular. In this case, the inner skirt 230 is composed of four skirt units, which respectively correspond to the front, back, left and right inner wall surfaces of the mounting opening 2100, thereby achieving a more stable positioning connection between the air-conditioning body 100 and the mounting opening 2100.

It is understood that the top plate 300 and the bottom plate 110 can be fixed by a plurality of bolts 500. The number of bolts 500 can be selected according to the size of the air conditioner body 100 and the size of the mounting opening 2100, such as four, six or more bolts, which are not specifically limited here. The plurality of bolts 500 are all arranged close to the inner wall of the mounting opening 2100 and are arranged at intervals along the circumference of the mounting opening 2100, thereby reducing the influence of the bolts 500 on the air inlet and outlet of the top-mounted air conditioner.

The ceiling-mounted air conditioner of the disclosed embodiment is provided with a support plate 200 installed at the bottom of the air conditioner main body 100, and a top plate 300 installed on the inner side of the vehicle top 2000 and connected to the air conditioner main body 100 by bolts 500. The support plate 200 is provided with an inner skirt 230 at one end facing the installation opening 2100. The inner skirt 230 is positioned and matched with the inner wall of the installation opening 2100 of the vehicle top 2000, so that the installer can quickly and accurately align the air conditioner main body 100 with the installation opening 2100, avoiding the installer to repeatedly go back and forth between the vehicle top 2000 and the vehicle interior for adjustment, thereby improving the installation efficiency and installation accuracy, and improving the safety of the installer. In addition, during the process of the installer installing the top plate 300, the design of the inner skirt 230 can also effectively prevent the air conditioner main body 100 from shaking or shifting, making it more efficient and convenient for the installer to tighten the bolts 500, while avoiding the air conditioner main body 100 from sliding and being damaged, thereby improving the safety of the installation.

Referring to Fig. 1, Fig. 14 and Fig. 15, it can be understood that the top-mounted air conditioner also includes a sealing ring 400. When the top-mounted air conditioner is installed on the top 2000 of the vehicle, the sealing ring 400 is arranged between the support plate 200 and the top 2000 of the vehicle. The sealing ring 400 is located between the mounting support plate 200 and the top 2000 of the vehicle, and plays an effective sealing role, so that the air inlet and the air outlet of the air conditioner body 100 are sealed and communicated with the internal environment of the RV through the mounting port 2100. The sealing ring 400 of the disclosed embodiment is made of an elastic material with compressible properties, such as sponge, pearl cotton, EVA (also known as ethylene-vinyl acetate copolymer), etc., so the sealing ring 400 can also achieve a better buffering effect, buffer the vibration between the air conditioner body 100 and the top 2000 of the vehicle, effectively reduce the vibration generated by the RV during bumpy driving to the air conditioner body 100, reduce the shaking of the air conditioner body 100, and improve the installation stability of the top-mounted air conditioner and the RV.

As shown in FIG. 13 and FIG. 19 , it can be understood that the support plate 200 is further provided with an outer skirt 220, which is located at the end of the support plate 200 facing downward, that is, the end facing the installation opening 2100, and the outer skirt 220 is arranged along the outer periphery of the support plate 200. The outer skirt 220 can be integrally manufactured and formed with the support plate 200, that is, formed by folding the outer periphery of the support plate 200 downward; or fixedly connected to the support plate 200 by welding or the like. The support plate 200 is positioned and matched with the outer wall of the sealing ring 400 through the outer skirt 220, so as to limit the position of the sealing ring 400 and make the installation of the sealing ring 400 more stable. In addition, the arrangement of the outer skirt 220 can also enhance the structural strength of the support plate 200, thereby improving the installation stability of the ceiling-mounted air conditioner.

Referring to FIG. 16 and FIG. 18 , it can be understood that when the bolt 500 is in a loose state, that is, when the bolt 500 is not fastened to the top plate 300, the gap between the outer skirt 220 and the upper end surface of the mounting opening 2100 is defined as D, and when the bolt 500 is in a locked state, that is, after the top-mounted air conditioner and the vehicle top 2000 are installed, the gap between the outer skirt 220 and the upper end surface of the mounting opening 2100 is H, which satisfies: 0＜H≤0.5D. It should be noted that when the above parameter range is met, the sealing ring 400 can achieve a certain compression after the bolt 500 is fastened, thereby forming a sealing fit with the vehicle top 2000, and at the same time, the cushioning and vibration reduction effect of the sealing ring 400 is also guaranteed.

As shown in FIG. 1 , FIG. 13 and FIG. 15 , it can be understood that the ceiling-mounted air conditioner further includes a shock-absorbing pad 600, which can play a buffering role. When the ceiling-mounted air conditioner is installed on the top 2000 of the vehicle, the shock-absorbing pad 600 is arranged between the air conditioner body 100 and the top 2000 of the vehicle, and the shock-absorbing pad 600 and the sealing ring 400 are arranged at intervals along the front and rear direction of the air conditioner body 100. It can be understood that the shock-absorbing pad 600 is arranged at the rear of the chassis 110, and the sealing ring 400 is arranged at the front of the chassis 110, so that the force of the air conditioner body 100 is more uniform, further reducing the vibration generated by the RV during bumpy driving to the air conditioner body 100, reducing the shaking of the air conditioner body 100, and improving the installation stability of the ceiling-mounted air conditioner and the RV.

Referring to FIG. 15 and FIG. 16 , it can be understood that, in order to facilitate the installation of the top plate 300 by the installer, the top plate 300 of an embodiment of the present disclosure adopts a design that can be pre-fixed with the support plate 200, for example, by movable buckles, clips, magnets, etc., so that the top plate 300 and the support plate 200 are pre-fixed and connected. Therefore, after the air conditioner body 100 is positioned by the support plate 200, the installer can pre-fix the top plate 300 with the support plate 200 in the RV, and can directly tighten the bolts 500 by operating with both hands to achieve the fastening of the top plate 300, without the need for one person to hold the top plate 300 with one hand and tighten the bolts 500 with the other hand, nor the need for one person to hold the top plate 300 and another person to tighten the bolts 500, thereby improving the installation efficiency and reducing the installation cost.

Referring to FIG. 15 and FIG. 20 , as one embodiment, the mechanism for achieving pre-fixation can be an adsorption member 350, which can be provided on the top plate 300, or on the inner skirt 230, or on both the top plate 300 and the inner skirt 230. The adsorption member 350 adsorbs and connects the top plate 300 and the inner skirt 230, thereby achieving pre-fixation between the two. For example, the adsorption member 350 can be a magnet, or can be adhesive, or other materials that can achieve adsorption of the top plate 300 and the inner skirt 230.

Referring to Figures 19 and 20, it can be understood that, in order to facilitate production and manufacturing, the adsorption member 350 of the embodiment of the present disclosure is a magnet, and the adsorption member 350 is arranged on the top plate 300. The inner skirt 230 is made of metal material, and the adsorption member 350 is adsorbed and connected to the inner skirt 230, thereby realizing the pre-fixation of the top plate 300, and its production cost is lower and the structure is more stable. There can be multiple adsorption members 350, and multiple adsorption members 350 are arranged at intervals along the circumference of the top plate 300. Each adsorption member 350 is fixed to the corresponding position of the top plate 300, so that the pre-fixed connection of the top plate 300 is more stable, and the risk of the top plate 300 falling off is effectively prevented.

It is understood that, as another embodiment, the top plate 300 is provided with a first adhesive component, and when the roof-mounted air conditioner is installed on the top of the vehicle 2000, the first adhesive component is used to bond the inner skirt 230. It is understood that the first adhesive component can be a material such as a double-sided adhesive tape, and the first adhesive component is set at a suitable position of the top plate 300. When the installer installs the top plate 300, the top plate 300 can be pre-fixed to the inner skirt 230 by the first adhesive component, so that the top plate 300 and the support plate 200 are pre-fixed, so that the installer can directly tighten the bolts 500 by both hands to achieve the fastening of the top plate 300, thereby improving the installation efficiency.

It is understandable that, as another embodiment, the first adhesive can also be used to bond the vehicle roof 2000. It is understandable that the first adhesive is set at a suitable position of the top plate 300. When the installer installs the top plate 300, the top plate 300 can be pre-fixed to the inner side of the vehicle roof 2000 or the inner wall of the installation opening 2100 by the first adhesive, so that the top plate 300 and the support plate 200 are pre-fixed, so that the installer can directly tighten the bolts 500 by both hands to achieve the fastening of the top plate 300, thereby improving the installation efficiency.

It is understandable that, as another embodiment, the inner skirt 230 is provided with a second adhesive member for bonding the top plate 300. It is understandable that the second adhesive member is arranged at a suitable position of the inner skirt 230, and when the installer installs the top plate 300, the top plate 300 and the support plate 200 can be pre-fixed by the adhesion of the second adhesive member to the top plate 300, so that the installer can directly tighten the bolts 500 by both hands to achieve the fastening of the top plate 300, thereby improving the installation efficiency.

As shown in FIG. 15 , FIG. 16 and FIG. 20 , it can be understood that the top plate 300 includes a positioning boss 330 and a mounting edge 340, and the mounting edge 340 is arranged around the periphery of the positioning boss 330. The top plate 300 can be formed by integral stamping, so that the strength of the positioning boss 330 and the mounting edge 340 is higher. The positioning boss 330 protrudes upward, and the positioning boss 330 is positioned and matched with the inner skirt 230. It can be understood that the positioning boss 330 includes an end plate 331 and a side plate 332, and the end plate 331 is located at one end of the positioning boss 330 facing the support plate 200, and the side plate 332 is arranged around the end plate 331 and connected to the mounting edge 340. The positioning boss 330 can be positioned and connected with the inner skirt 230 through the side plate 332 or the end plate 331. When the side plate 332 is used to abut against the inner skirt 230, the inner skirt 230 can limit the displacement of the top plate 300 in the horizontal direction of the vehicle top 2000, and the mounting edge 340 abuts against the inner side of the vehicle top 2000 to limit the displacement of the top plate 300 in the thickness direction of the vehicle top 2000, thereby achieving accurate alignment of the top plate 300. When the end plate 331 is used to abut against the inner skirt 230, the inner skirt 230 can limit the displacement of the top plate 300 in the thickness direction of the vehicle top 2000, and the mounting edge 340 abuts against the inner side of the vehicle top 2000 to limit the displacement of the top plate 300 in the thickness direction of the vehicle top 2000, while the side plate 332 can abut against the inner wall of the mounting opening 2100 to limit the displacement of the top plate 300 in the horizontal direction of the vehicle top 2000. The disclosed embodiment can effectively prevent the top plate 300 from shaking inside the installation opening 2100 , thereby preventing the air conditioner body 100 from shaking therewith, thereby improving the installation accuracy of the top plate 300 and making it easier for installers to tighten the bolts 500 between the top plate 300 and the chassis 110 .

As shown in FIG. 17 and FIG. 18 , in one embodiment of the present disclosure, the side plate 332 of the positioning boss 330 is positioned and connected with the inner skirt 230, and one end of the inner skirt 230 facing the top plate 300 abuts against the mounting edge 340. Therefore, when the installer installs the top plate 300 and tightens the bolt 500, the installer cannot further apply the tightening force of tightening the bolt 500 when the inner skirt 230 abuts against the mounting edge 340. At this time, it indicates that the bolt 500 has been tightened in place, and the locking force meets the design standard, avoiding excessive prestress damage to the chassis 110 due to excessive locking force. Therefore, when tightening and installing the top plate 300, it is not necessary to use a torque wrench to determine whether the locking force is appropriate, which improves the convenience of installation and improves the reliability of the installation of the roof-mounted air conditioner.

As shown in Figure 20, it can be understood that the magnet can be arranged on the outer peripheral edge of the positioning boss 330, so that the top plate 300 can be pre-fixed and connected while taking into account the positioning of the top plate 300 and the inner skirt 230, thereby further improving the installation efficiency of the roof-mounted air conditioner and the RV.

As shown in FIG. 20 , it can be understood that the end of the positioning boss 330 facing the support plate 200 is provided with an end plate 331, the second communication hole 310 is opened in the end plate 331, and the end plate 331 is provided with a fixing hole 333, and the fixing hole 333 is used for the bolt 500 to pass through and be fixed to the end plate 331. It can be understood that the fixing hole 333 is provided on the periphery of the second communication hole 310, so as to avoid the bolt 500 passing through the fixing hole 333 to affect the air inlet channel and the air outlet channel.

Referring to Figures 21, 22, 23 and 24, another embodiment of the roof-mounted air conditioner disclosed herein has a structure similar to that of the previous embodiment, wherein the inner skirt 230 is positioned and matched with the side plate 332 of the positioning boss 330, thereby limiting the displacement of the top plate 300 in the horizontal direction of the vehicle top 2000. However, the inner skirt 230 of the disclosed embodiment is provided with a position indicating convex edge 240, which is provided at the end of the inner skirt 230 away from the support plate 200 and extends toward the top plate 300, and correspondingly, the mounting edge 340 is provided with a through hole 360, which is used for the position indicating convex edge 240 to pass through. It is understandable that when the installer installs the top plate 300 and tightens the bolts 500, the position-indicating convex edge 240 penetrates the lower surface of the installation edge 340, so that the installer can observe the protruding position-indicating convex edge 240, and prompts the installer that the bolt 500 has been installed in place, the locking force meets the design standard, and there is no need to continue tightening the bolt 500, so that the locking force can meet the design requirements. The position-indicating convex edge 240 can better feedback to the installer whether the locking force of the bolt 500 is appropriate, and can give the installer effective indicative feedback to avoid the top plate 300 being not installed in place due to insufficient locking force, or the chassis 110 being damaged by excessive prestress due to excessive locking force. Therefore, when tightening the top plate 300 for installation, it is not necessary to use a torque wrench to determine whether the locking force is appropriate, which improves the convenience of installation and improves the reliability of the installation of the roof-mounted air conditioner.

As shown in FIG. 22 , it can be understood that the height of the through hole 360 exposed by the position-indicating convex edge 240 is defined as S, and the height S satisfies being greater than or equal to 0 and less than or equal to 2 mm. It should be noted that the height S is the size of the through hole 360 exposed by the position-indicating convex edge 240 along the up and down direction of the air conditioner body 100. When the height S satisfies the above parameter range, the locking force can meet the design requirements and can avoid the problem caused by excessive locking force. When the height S is greater than the above parameter range, even if the installer ignores that the position-indicating convex edge 240 has protruded from the lower surface of the installation edge 340 and continues to lock, after the installer completes the positioning and installation of the air conditioner body 100, when installing the indoor air outlet component 700, the indoor air outlet component 700 cannot be installed because the position-indicating convex edge 240 protrudes too much. At this time, in order to avoid the position-indicating convex edge 240 from supporting the indoor air outlet component 700, the installer can only loosen the bolt 500 to make the position-indicating convex edge 240 shrink back a part upward until the height S of the protruding position-indicating convex edge 240 meets the design requirements before the indoor air outlet component 700 can be installed. Therefore, the locking force of the top plate 300 can be controlled by designing the positioning convex edge 240 to meet the design requirements, thereby ensuring that the overall fixing force of the ceiling-mounted air conditioner is within a suitable range.

The disclosed embodiment also provides a vehicle, including the roof-mounted air conditioner of the above embodiment. The vehicle may be a motorhome or other types of vehicles. Since the vehicle adopts all the technical solutions of the roof-mounted air conditioner of the above embodiment, it at least has all the beneficial effects brought by the technical solutions of the above embodiment, which will not be described in detail here.

The embodiments of the present disclosure are described in detail above in conjunction with the accompanying drawings, but the present disclosure is not limited to the above embodiments, and various changes can be made within the knowledge scope of ordinary technicians in the relevant technical field without departing from the purpose of the present disclosure.
