Description

Technical Field

[0001] The present invention belongs to the technical field of vehicle air conditioners, and in particular relates to a roof-mounted vehicle air conditioner structure. Background Art

[0002] A roof-mounted car air conditioner, also known as a parking air conditioner, is a new type of car air conditioning system that can maintain a stable temperature inside the car when the car is stopped, providing passengers with a comfortable environment. When installing a parking air conditioner, first, you need to open a skylight on the roof and fix the sealing strip. Then, extend the indoor unit of the air conditioner into the car through the skylight. Then, install the outdoor unit of the air conditioner through the studs 2 and the crossbeam 3 (such as Figure 1 Then go back into the car, put the interior panel on the indoor unit and fix it to the roof panel. Finally, connect the power supply to complete the installation of the parking air conditioner.

[0003] Due to the limited space inside the vehicle, currently only two parallel beams 3 are generally used to fix the outdoor unit to the roof. This has the following disadvantages: since the roof material is flexible, if the position of the roof between the two beams 3 is hit by external force (such as falling stones, etc.), the roof at this position will be dented or cracked, which may cause a gap between the sealing strip and the roof. On rainy days, rainwater will flow into the vehicle along the dented or cracked position of the roof, causing unnecessary trouble to the car owner. Summary of the Invention

[0004] The purpose of the present invention is to address the shortcomings of the existing technology and provide a roof-mounted vehicle air-conditioning structure to solve the technical problem in the existing technology that the parking air-conditioning cannot ensure the sealing between the outdoor unit and the roof when the roof is hit, deformed or cracked after installation.

[0007] As a preferred embodiment of the above technical solution, a right-angle plate is retractably installed on the top of the ear plate, the top of the right-angle plate is against the top of the movable plate, the top of the right-angle plate is against the inner side of the roof, and a card block is inserted through the right-angle plate, and the card block is against the top of the ear plate.

[0008] As a preferred embodiment of the above technical solution, a card seat is provided in the card plate, a straight plate is provided on the top of the card seat, an extrusion cavity is formed between the straight plate and the inner wall of the card plate, a top plate and a bottom plate are slidably installed in the extrusion cavity, a rubber ball is installed between the top plate and the bottom plate, an elastic member three is connected between the bottom plate and the card seat, an extrusion plate is installed on the top of the card plate inner cavity through the elastic member two, the extrusion plate is located above the top plate, a connecting plate is fixed at one end of the pressure rod located inside the ear plate, a rotating drum is also installed on the top of the connecting plate, a limiting plate is provided on the periphery of the rotating drum, the limiting plate is against the bottom of the extrusion plate and the elastic member two is in a compressed state, a discharge hole is provided on the side of the card plate close to the ear plate, and the discharge hole is located above the right-angle plate.

[0009] As a preferred embodiment of the above technical solution, a fixed shaft is fixed on the top of the connecting plate, the rotating drum is rotatably installed on the periphery of the fixed shaft, a guide groove is opened on the periphery of the rotating drum, a guide rod is fixed on the inner wall of the clamping plate, and the guide rod is sleeved in the guide groove.

[0010] As a preferred embodiment of the above technical solution, there is a partition between the top plate and the bottom plate, and the partition divides the top plate and the bottom plate into two storage spaces, the upper storage space is for placing rubber balls, and the lower storage space is for placing air balls.

[0011] As a preferred embodiment of the above technical solution, the partition and the bottom plate are both provided with through holes, the through holes are close to the discharge hole, and a needle is provided on the side of the inner wall of the card plate close to the discharge hole. The needle is located above the discharge hole, and the needle passes through the through hole when the partition and the bottom plate move downward.

[0012] As a preferred embodiment of the above technical solution, a water inlet hole is provided on the top of the ear plate, and a circle of surrounding plates is provided on the outer periphery of the top of the connecting plate.

[0013] The beneficial effects of the present invention are: 1. In the present invention, the outer housing can be fixed to the roof on all sides by means of the clamping plate and the ear plate against the inner side of the roof, and in conjunction with the two cross beams, thereby effectively preventing the roof from being sunken, deformed, or cracked at the position between the two cross beams when impacted by external force, thereby effectively preventing rainwater from flowing into the vehicle through the sunken, deformed, or cracked position of the roof, thereby improving the sealing between the outer housing and the roof after installation. The two clamping plates, the two ear plates, and the two cross beams can not only ensure the fixation of the outer housing to the roof, but also effectively prevent the outer housing from being displaced relative to the roof. This can, on the one hand, improve the stability of the outer housing after installation, and on the other hand, effectively prevent the outer housing from being deformed due to displacement, thereby preventing the outer housing from being deformed due to displacement, thereby preventing rainwater or dust from entering the vehicle. 2. In the present invention, the movable panel abuts against the roof. In this way, when the roof is hit, the movable panel, the pressure rod, and the elastic member can effectively cushion the roof, thereby effectively preventing the roof from sinking and deforming, preventing gaps from forming between the sealing strip and the roof, and preventing rainwater from flowing into the vehicle through the sunken, deformed, or cracked areas of the roof, thereby improving the sealing between the outer casing and the roof after installation. 3. In the present invention, when the roof is subjected to a large impact, the movable plate is squeezed and moved downward by the roof, and the movable plate drives the connecting plate to move the rotating drum downward. When the rotating drum moves downward, due to the restriction of the guide groove and the guide rod, the rotating drum rotates, thereby causing the limit plate to separate from the extrusion plate. The extrusion plate is now released from restriction, and the elasticity of the elastic member 2 causes the extrusion plate to move downward rapidly. After the extrusion plate moves downward, it squeezes the top plate, causing the top plate to move downward, and the top plate squeezes the rubber ball and the bottom plate to move downward. At this time, the elastic member 3 is compressed, and the rubber ball will break under the pressure of the top plate. When the space between the top plate and the bottom plate moves to the discharge hole, the sealant is sprayed from the discharge hole, so that the sealant will block the gap between the sealing strip and the roof, thereby effectively preventing rainwater from flowing into the car through the gap between the sealing strip and the roof, thereby improving the sealing performance of the outer casing and the roof after installation; 4. In the present invention, when the extrusion plate moves downward to extrude the top plate, the top plate squeezes the rubber balls and balloons below. After the rubber balls and balloons are broken, the balloons first eject high-pressure gas through the discharge hole, thereby cleaning the gap between the sealing strip and the roof and blowing water or dust to the outside. In this way, after the sealant is ejected, the sealant will not be contaminated by water or dust, thereby ensuring the sealing performance of the sealant and effectively preventing rainwater from flowing into the vehicle through the gap between the sealing strip and the roof, thereby improving the sealing performance of the outer casing and the roof after installation.

[0016] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts shall fall within the scope of protection of the present invention.

[0017] like Figure 1-Figure 3 As shown, a roof-mounted vehicle air conditioner structure includes an outer casing 1, studs 2 and a crossbeam 3, and the structure also includes: The outer housing 1 is provided with two fixing plates 5 at the bottom, and a plurality of mounting seats 18 are provided on the inner sides of the fixing plates 5 and the inner sides of the fixing plates 4. The fixing plates 4 and the fixing plates 5 are fixed to the plurality of mounting seats 18 by bolts 19. The fixing plates 4 are perpendicular to the beams 3, and the length of the fixing plates 4 is equal to the distance between the two beams 3. A lug plate 41 is provided on the side of the clamping plate 4 away from the fixing plate 5 , and the lug plate 41 is against the inner side of the roof.

[0018] In actual use of this embodiment, the clamping plate 4 and the ear plate 41 are pressed against the inner side of the roof, and the two cross beams 3 are used to fix the outer housing 1 to the roof on all sides. This effectively prevents the roof from being sunken or cracked at the position between the two cross beams 3 when impacted by external forces, thereby effectively preventing rainwater from flowing into the vehicle through the sunken or cracked position of the roof, thereby improving the sealing performance of the outer housing 1 and the roof after installation. The two clamping plates 4, the two ear plates 41 and the two cross beams 3 can ensure that the outer housing 1 is fixed to the roof while effectively preventing the outer housing 1 from being displaced relative to the roof. This can improve the stability of the outer housing 1 after installation and effectively prevent deformation of the outer housing 1 after displacement, thereby preventing rain or dust from entering the vehicle.

[0019] Furthermore, a plurality of pressure rods 61 are installed through the top of the ear plate 41 , a movable plate 6 is provided on the top of the pressure rod 61 , and an elastic member 62 is connected between the movable plate 6 and the ear plate 41 .

[0020] A plurality of right-angle plates 7 are installed telescopically on the top of the ear plate 41. The top of the right-angle plate 7 abuts against the top of the movable plate 6, and the top of the right-angle plate 7 abuts against the inner side of the roof. A card block 71 is inserted through the right-angle plate 7, and the card block 71 abuts against the top of the ear plate 41.

[0021] In one case of this embodiment, the elastic member 62 can be a spring or other elastically retractable component; the snap-on retractable installation of the right-angle plate 7 can make the top of the right-angle plate 7 move downward when squeezed.

[0022] In actual use of this embodiment, the movable plate 6 abuts against the roof. In this way, when the roof is hit, the movable plate 6, the pressure rod 61 and the elastic member 1 62 can effectively cushion the roof, thereby effectively preventing the roof from sinking and deforming, preventing a gap from forming between the sealing strip and the roof, and preventing rainwater from flowing into the vehicle along the sunken, deformed or cracked parts of the roof, thereby improving the sealing performance between the outer housing 1 and the roof after installation. When installing the card plate 4, since the card plate 4 needs to be moved upward and close to the inner side of the roof, if the movable plate 6 is in an active state, the elastic member 62 may be compressed after the card plate 4 moves upward, resulting in a smaller movable space for the movable plate 6, thereby reducing the buffering capacity of the movable plate 6 on the roof. At this time, the right-angle plate 7 with the card block 71 inserted is abutted against the inner side of the roof, avoiding direct contact between the movable plate 6 and the inner side of the roof, thereby ensuring that the movable plate 6 has enough space to move downward; when the card plate 4 is installed, the top of the right-angle plate 7 is abutted against the inner side of the roof. At this time, the card block 71 can be removed from the right-angle plate 7, so that when the roof is subjected to external force, the roof will squeeze the movable plate 6 through the right-angle plate 7.

[0023] like Figure 1-Figure 5As shown, a card seat 42 is provided in the card plate 4, and a straight plate 43 is provided on the top of the card seat 42. An extrusion cavity 44 is formed between the straight plate 43 and the inner wall of the card plate 4. A top plate 11 and a bottom plate 13 are slidably installed in the extrusion cavity 44. A rubber ball 15 is installed between the top plate 11 and the bottom plate 13. An elastic member three 14 is connected between the bottom plate 13 and the card seat 42. An extrusion plate 10 is installed on the top of the inner cavity of the card plate 4 through an elastic member two 101. The extrusion plate 10 is located above the top plate 11. A connecting plate 8 is fixed to one end of the pressure rod 61 located inside the ear plate 41. A rotating drum 9 is also installed on the top of the connecting plate 8. A limiting plate 93 is provided on the periphery of the rotating drum 9. The limiting plate 93 abuts against the bottom of the extrusion plate 10 and makes the elastic member two 101 in a compressed state. A discharge hole 47 is provided on the side of the card plate 4 close to the ear plate 41. The discharge hole 47 is located above the right-angle plate 7.

[0024] A fixed shaft 91 is fixed on the top of the connecting plate 8 , and the rotating drum 9 is rotatably mounted on the periphery of the fixed shaft 91 . A guide groove 92 is opened on the periphery of the rotating drum 9 , and a guide rod 45 is fixed on the inner wall of the clamping plate 4 , and the guide rod 45 is sleeved in the guide groove 92 .

[0025] In one case of this embodiment, the elastic member 2 101 and the elastic member 3 14 can both be springs or other elastically expandable and contractible components; the rubber ball 15 is an elastic sphere with sealant inside; each movable plate 6 corresponds to a set of connecting plates 8, rotating drum 9, extrusion plate 10, top plate 11, bottom plate 13 and rubber ball 15.

[0026] In actual application of this embodiment, when the roof is hit hard, the movable plate 6 cannot buffer the roof, and the roof will still be concave and deformed. At this time, since the movable plate 6 is squeezed and moved downward by the roof, the movable plate 6 will drive the connecting plate 8 to move the drum 9 downward. When the drum 9 moves downward, due to the restriction of the guide groove 92 and the guide rod 45, the drum 9 rotates, thereby causing the limit plate 93 to break away from the extrusion plate 10. The extrusion plate 10 is now released from the restriction, and the elasticity of the elastic member 101 causes the extrusion plate 10 to move downward quickly. The extrusion plate 10 moves downward. After the movement, the top plate 11 is pressed, causing the top plate 11 to move downward, and the top plate 11 presses the rubber ball 15 and the bottom plate 13 downward. At this time, the elastic member 3 14 is compressed, and the rubber ball 15 is broken under the pressure of the top plate 11. When the space between the top plate 11 and the bottom plate 13 moves to the discharge hole 47, the sealant is sprayed out from the discharge hole 47. In this way, the sealant will block the gap between the sealing strip and the roof, thereby effectively preventing rainwater from flowing into the vehicle through the gap between the sealing strip and the roof, thereby improving the sealing performance of the outer housing 1 and the roof after installation. By arranging a plurality of movable plates 6, a plurality of connecting plates 8, a plurality of rotating drums 9, a plurality of extrusion plates 10, a plurality of top plates 11, a plurality of bottom plates 13 and a plurality of rubber balls 15, the roof is located between the two cross beams 3, and no matter where it is hit by external force, the above structure can achieve precise glue repairing operation, thereby further effectively preventing rainwater from flowing into the vehicle through the gap between the sealing strip and the roof, and further improving the sealing performance of the outer casing 1 and the roof after installation.

[0027] Furthermore, there is a partition 12 between the top plate 11 and the bottom plate 13. The partition 12 divides the top plate 11 and the bottom plate 13 into two storage spaces. The upper storage space is used to place the rubber balls 15, and the lower storage space is used to place the balloons 16.

[0028] In one aspect of this embodiment, the balloon 16 is an elastic sphere filled with compressed air.

[0029] In actual application of this embodiment, when the extrusion plate 10 moves downward to squeeze the top plate 11, the top plate 11 squeezes the rubber ball 15 and the balloon 16 below. After the rubber ball 15 and the balloon 16 are broken, the balloon 16 first sprays high-pressure gas through the discharge hole 47, so that the gap between the sealing strip and the roof can be cleaned and water or dust can be blown to the outside. In this way, after the sealant is sprayed out, the sealant will not be contaminated by water or dust, thereby ensuring the sealing performance of the sealant and effectively preventing rainwater from flowing into the car through the gap between the sealing strip and the roof, thereby improving the sealing performance of the outer casing 1 and the roof after installation.

[0030] Furthermore, a through hole 17 is provided on both the partition 12 and the bottom plate 13, and the through hole 17 is close to the discharge hole 47. A needle 46 is provided on the side of the inner wall of the card plate 4 close to the discharge hole 47, and the needle 46 is located above the discharge hole 47. When the partition 12 and the bottom plate 13 move downward, the needle 46 passes through the through hole 17.

[0031] In actual application of this embodiment, the pressure of the downward movement of the extrusion plate 10 may not be able to rupture both the rubber ball 15 and the air ball 16. At this time, during the downward movement of the rubber ball 15 and the air ball 16, the rubber ball 16 and the air ball 15 will successively contact the needle 46, and the rubber ball 16 and the air ball 15 will be punctured by the needle 46, thereby ensuring that the rubber ball 16 and the air ball 15 are both ruptured after moving downward, so that the high-pressure gas and sealant can be smoothly ejected from the discharge hole 47, further effectively preventing rainwater from flowing into the car through the gap between the sealing strip and the roof, and further improving the sealing of the outer casing 1 and the roof after installation.

[0032] like Figure 5 As shown, a water inlet hole 411 is provided on the top of the ear plate 41 , and a circle of surrounding plates 81 is provided on the periphery of the top of the connecting plate 8 .

[0033] In one aspect of this embodiment, a water-absorbing cloth or the like may be provided on the top of the connecting plate 8 .

[0034] In actual use of this embodiment, when cracks appear on the roof, the movable panel 6 will not be squeezed. However, rainwater will still flow into the vehicle through the gap between the sealing strip and the roof. By providing the water inlet hole 411, rainwater can flow through the water inlet hole 411 into the space formed by the connecting plate 8 and the surrounding plate 81. When the water volume reaches a certain weight, the connecting plate 8 will move downward, thereby rotating the drum 9, which can also cause the sealant to be sprayed out to block the gap between the sealing strip and the roof, further effectively preventing rainwater from flowing into the vehicle through the gap between the sealing strip and the roof, and further improving the sealing performance of the outer housing 1 and the roof after installation. In order to ensure that water can move the connecting plate 8 downward, the water-absorbing cloth absorbs water so that the space formed by the connecting plate 8 and the surrounding plate 81 can accommodate more water, thereby ensuring that the connecting plate 8 can move downward and the sealant can be sprayed out.

[0035] The basic principles, main features, and advantages of the present invention are shown and described above. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are merely illustrative of the principles of the present invention. Various changes and modifications may be made to the present invention without departing from the spirit and scope of the present invention, and such changes and modifications fall within the scope of the invention as claimed.
