DETAILED DESCRIPTION

[0026] In order to make the technical problems, technical solutions and beneficial effects solved by the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0027] like Figure 1 and Figure 2 As shown, an embodiment of the utility model provides a vehicle, in which only the roof portion of the vehicle is shown. The vehicle includes an air conditioner 4 and a body structure, and the body structure includes a vehicle air conditioner installation structure.

[0028] The vehicle air conditioner mounting structure includes an air conditioner bracket 3 and a first fastener. The air conditioner bracket 3 includes an air conditioner mounting portion 31 and a roof fastening portion 32 . The roof fastening portion 32 is fixedly connected to the air conditioner mounting portion 31 . The air conditioner mounting portion 31 is connected to the air conditioner 4 .

[0029] The roof fastening portion 32 extends vertically, and the first fastener is arranged transversely and connected to the roof fastening portion 32 to fix the roof fastening portion 32 and the roof.

[0030] like Figure 4 and Figure 5As shown, during the driving process of the vehicle, especially during the turning process of the vehicle, since the air conditioner 4 is installed on the roof and the weight of the air conditioner 4 is large, the air conditioner 4 will have a relatively obvious lateral movement trend, and this movement trend will cause the air conditioner 4 to transmit a large lateral force to the roof. In the vehicle air conditioner installation structure of the utility model, the first fastener connecting the roof and the roof fastening part 32 is arranged horizontally, and the lateral force generated when the air conditioner 4 vibrates horizontally will act on the first fastener along the axial direction of the first fastener, and then be transmitted horizontally to the roof, so as to avoid the situation in the prior art that the installation part is subjected to lateral shear force and is easy to break and deform when the air conditioner 4 and the roof are connected by vertical bolts.

[0031] In the vehicle of the utility model, the roof fastening portion 32 of the air conditioner bracket 3 extends vertically, the first fastener is arranged transversely and connects the roof fastening portion 32 and the roof, and the air conditioner mounting portion 31 of the air conditioner bracket 3 is connected to the air conditioner 4. Since the first fastener connecting the roof fastening portion 32 of the air conditioner bracket 3 and the roof is arranged transversely, the transverse force generated when the air conditioner 4 vibrates transversely will act on the mounting portion along the axial direction of the first fastener, so as to avoid the situation in the prior art that the mounting portion is subjected to transverse shear force and is easily broken and deformed when the air conditioner 4 and the roof are connected by vertical bolts.

[0032] In one embodiment, a blocking portion (not shown) is further included, which is mounted on the bottom surface of the air conditioner 4. The air conditioner mounting portion 31 extends transversely, and the opposite surface of the position where the air conditioner mounting portion 31 is connected to the roof fastening portion 32 abuts against the blocking portion. The transverse extension of the air conditioner mounting portion 31 means that the air conditioner mounting portion 31 extends along the bottom surface of the air conditioner 4. Figure 4 The air conditioner mounting portion 31 extends in the width direction of the vehicle, and supports the bottom surface of the air conditioner 4 and is fixedly connected to the air conditioner 4 through vertical fasteners.

[0033] The laterally extending air-conditioning mounting portion 31 is usually fixedly connected to the air-conditioning 4 by means of vertically arranged fasteners. Since the opposite surface of the air-conditioning mounting portion 31 adjacent to the roof fastening portion 32 abuts against the blocking portion, when the air-conditioning 4 vibrates laterally relative to the roof, the blocking portion can withstand the lateral force transmitted to the air-conditioning mounting portion 31 to avoid the vertically arranged fasteners connecting the air-conditioning mounting portion 31 and the air-conditioning 4 from being subjected to lateral shear force, and at the same time, it can also avoid the fasteners connecting the air-conditioning mounting portion 31 and the air-conditioning 4 from loosening.

[0034] In one embodiment, the blocking portion is fixed on the bottom surface of the air conditioner 4 and protrudes from the bottom surface of the air conditioner 4 .

[0035] In other embodiments, a groove can be opened at the bottom of the air conditioner 4, and the air conditioner mounting part 31 is placed in the groove. The opposite surface of the position on the air conditioner mounting part 31 connected to the roof fastening part 32 can abut the side wall of the groove, and the side wall of the groove constitutes a blocking part.

[0036] In one embodiment, a first connecting hole 13 extending transversely therethrough is provided on the roof, a second connecting hole 33 extending transversely therethrough is provided on the roof fastening portion 32 , and the first fastener is transversely inserted into the second connecting hole 33 and the first connecting hole 13 .

[0037] In one embodiment, if Figure 4 and Figure 5 As shown, the first fastener includes a first bolt 5 and a first nut 6. One end of the rod of the first bolt 5 passes through the second connection hole 33 and the first connection hole 13 and is fastened by the first nut 6 to fix the air conditioner bracket 3 on the roof. At this time, the lateral arrangement direction of the first fastener refers to the insertion direction of the rod of the first bolt 5.

[0038] In one embodiment, a second fastener is further included, the air conditioner 4 is provided with a first mounting hole, the air conditioner mounting portion 31 is provided with a second mounting hole 34 which is vertically penetrated, and the second mounting hole 34 is a long hole extending in the left-right direction of the vehicle. The second fastener fixes the air conditioner mounting portion 31 to the air conditioner 4 through the second mounting hole 34 and the first mounting hole on the air conditioner 4.

[0039] When installing the second fastener, the second fastener can be moved in the second mounting hole 34 along the left-right direction of the vehicle to adjust its position, so that the second fastener is inserted into the first mounting hole.

[0040] In one embodiment, the second fastener includes a second bolt 7 and a second nut, the second nut is fixed on the air conditioner 4 and located at the edge of the first mounting hole, and the second bolt 7 can pass through the second mounting hole 34 and be connected to the second nut.

[0041] In one embodiment, two first mounting holes are provided, and the two first mounting holes are spaced apart along the front-rear direction of the vehicle. Two corresponding second mounting holes 34 are provided at positions corresponding to the two first mounting holes on the air-conditioning mounting plate, and each second bolt 7 passes through the corresponding second mounting hole 34 and is connected to the corresponding second nut.

[0042] In one embodiment, it further includes a support frame 1, one side of which is connected to the top of the vehicle side wall or the roof, and the air conditioner bracket 3 is fixedly connected to the support frame 1. During installation, the air conditioner bracket 3 and the first fastener can be first installed on the support frame 1 to form a module, and then the support frame 1 in the module is connected to the top of the vehicle side wall or the roof. Compared with installing multiple air conditioner brackets 3 and first fasteners on the roof separately, this design is easy to install and improves installation efficiency.

[0043] In one embodiment, a boss is further included, which is fixed on the support frame 1 and protrudes from the top surface of the support frame 1, and the first fastener fixes and connects the roof fastening portion 32 and the boss. Since the boss connected to the first fastener protrudes from the top surface of the support frame 1, there is no interference structure around the boss on the support frame 1, which facilitates the operation of installing the first fastener on the boss.

[0044] In one embodiment, the boss includes a first boss 11, which is in a long strip shape extending in the front-rear direction of the vehicle, and the air conditioner bracket 3 and the first fastener are both arranged in a plurality of intervals along the length direction of the first boss 11, and the plurality of first fasteners connect the first boss 11 and the roof fastening parts 32 of the plurality of air conditioner brackets 3. The long strip-shaped first boss 11 has a high structural strength, and the continuously extending boss can better prevent rainwater from entering the bottom of the air conditioner 4.

[0045] In one embodiment, if Figure 2 As shown, the first boss 11 is provided with a plurality of first connection holes 13 spaced apart along the front-rear direction of the vehicle, the first connection holes 13 penetrate the first boss 11 along the left-right direction of the vehicle, a plurality of air-conditioning brackets 3 correspond one-to-one to the plurality of first connection holes 13, and correspondingly, the roof fastening portion 32 is provided with a second connection hole 33 penetrating along the left-right direction of the vehicle, the rod portion of the first bolt 5 passes through the corresponding second connection hole 33 and the first connection hole 13 and is fastened by the first nut 6.

[0046] Specifically, before installing the air conditioner 4, first fix the first nut 6 on the inner wall of the first boss 11 in the left and right directions of the vehicle, and the first nut 6 is located at the edge of the corresponding first connecting hole 13, and then adjust the position of the air conditioner 4 until the second connecting hole 33 on the roof fastening part 32 is aligned with the first connecting hole 13, and finally, pass the rod of the first bolt 5 through the second mounting hole 34 and threadedly connected with the first nut 6.

[0047] In one embodiment, if Figure 3 As shown, the air conditioner bracket 3 includes an air conditioner mounting plate and a roof fastening plate, the roof fastening plate is formed by bending one side of the air conditioner mounting plate toward the bottom, the air conditioner mounting portion 31 is formed on the air conditioner mounting plate, and the roof fastening portion 32 is formed on the roof fastening plate. The air conditioner bracket 3 has a simple structure and is easy to process.

[0048] In one embodiment, if Figures 3 to 5 As shown, the roof fastening plate extends in the front-to-rear direction of the vehicle, the first fastener is arranged in a direction perpendicular to the side surface in the thickness direction of the roof fastening plate, and the side surface in the thickness direction of the roof fastening plate is attached to the first boss 11 on the roof, so that the roof fastening plate is in surface contact with the first boss 11, increasing the contact area, so that the lateral force generated by the lateral vibration of the air conditioner 4 can be transmitted to the first boss 11 through the first contact surface 17, and then transmitted to the roof, which is beneficial to the transmission of force.

[0049] Moreover, the first contact surface 17 between the roof fastening plate and the first boss 11 is perpendicular to the lateral arrangement direction of the first fastener, thereby avoiding the generation of a vertical component when the lateral force is transmitted to the first boss 11 through the first contact surface 17, thereby causing sliding between the air conditioning bracket 3 and the first boss 11.

[0050] In one embodiment, the roof fastening plate is attached to the outer side wall of the first boss 11 in the left-right direction of the vehicle, one end of the rod of the first bolt 5 passes through the second connecting hole 33 and the first connecting hole 13 in sequence, and the head of the first bolt 5 is pressed on the roof fastening plate.

[0051] In one embodiment, the air conditioning mounting plate extends in a horizontal direction, and the top surface of the air conditioning mounting plate is suitable for being attached to the bottom surface of the air conditioner 4 to increase the contact area between the air conditioning mounting plate and the bottom of the air conditioner 4 and improve the stability of the air conditioning mounting plate in supporting the air conditioner 4.

[0052] Moreover, the contact surface between the air-conditioning mounting plate extending in the horizontal direction and the bottom of the air-conditioning 4 is a horizontal surface. When the air-conditioning 4 pressed on the air-conditioning mounting plate transmits pressure to the air-conditioning mounting plate through the contact surface, the direction of the contact surface is perpendicular to the direction of the pressure to avoid the generation of component forces in other directions when the pressure transmits the force to the air-conditioning mounting plate through the contact surface, thereby affecting the stability of the connection between the air-conditioning 4 and the air-conditioning mounting plate.

[0053] In one embodiment, if Figure 4 and Figure 5 As shown, it also includes a first sealing gasket 8, which is arranged between the support frame 1 and the bottom surface of the air conditioner 4, and is spaced apart from the side of the first boss 11 connected to the roof fastening part 32. The first sealing gasket 8 extends along the length direction of the first boss 11 to both ends of the first boss 11 to form a sealing area with the first boss 11, thereby improving the sealing between the support frame 1 and the bottom surface of the air conditioner 4 and preventing water from entering the air conditioner 4. The first sealing gasket 8 also performs waterproof sealing on the first fastener to prevent corrosion risks. Moreover, since the first connecting hole 13 is arranged on the first boss 11 protruding upward, the height of the first fastener is higher than the height of the bottom surface of the first sealing gasket 8. Even if the first sealing gasket 8 fails, the first fastener will not be soaked in water.

[0054] In one embodiment, two first bosses 11 are arranged at intervals, and the boss also includes a second boss 18. The support frame 1 is provided with a first boss 11 on both sides of the left and right directions of the vehicle, and two second bosses 18 are arranged at intervals. The two second bosses 18 are respectively located at both ends of the first boss 11 and extend to connect with the two first bosses 11 to form a frame for supporting the bottom surface of the air conditioner 4.

[0055] After the bottom surface of the air conditioner 4 is pressed onto the frame, it can be sealed with the top surface of the frame to prevent external rainwater from entering the bottom of the air conditioner 4 through the gap between the air conditioner 4 and the top surface of the support frame 1, further improving the waterproof performance of the air conditioner 4. Moreover, the closed frame has a higher structural strength and better stability in carrying the air conditioner 4.

[0056] In one embodiment, a mounting opening 100 communicating with the interior space of the vehicle is provided on the roof, and a closed frame is provided around the mounting opening 100. The boss in the form of a closed frame supports the bottom surface of the air conditioner, preventing rainwater from outside from entering the bottom of the air conditioner, and further preventing rainwater from entering the interior of the vehicle through the mounting opening 100.

[0057] In the vehicles of the prior art, an air conditioning base plate is installed on the roof, the roof air conditioner 4 is installed on the air conditioning base plate, and interior decorations such as interior lights and middle roof plates are installed under the air conditioning base plate. This structural form causes a high occupation of the upper space of the vehicle. In order to maintain the net height inside the vehicle, the height of the entire vehicle is increased, which in turn leads to higher requirements for the height limit of the vehicle and the stability of the entire vehicle. In the vehicle of the utility model, the air conditioning base plate is cancelled, the air conditioner is installed on the support frame 1, and the bottom of the air conditioner 4 is connected to the interior of the vehicle through the installation port 100. Therefore, this space can be fully utilized, and the interior decorations such as interior lights and middle roof plates are arranged within the space range of the installation port 100 to compress the upper space occupied and reduce the height of the entire vehicle. At the same time, the original air conditioning base plate is nearly 100 kilograms. Cancelling the air conditioning base plate can effectively reduce the weight of the entire vehicle and save the material cost of the entire vehicle.

[0058] In one embodiment, a second sealing gasket 9 is further included, and the second sealing gasket 9 is arranged between the top surface of the boss and the bottom surface of the air conditioner 4. The installation position of the second sealing gasket 9 is higher than the bottom surface of the first sealing gasket 8. Even if the first sealing gasket 8 fails, the second sealing gasket 9 can prevent rainwater from entering the bottom of the air conditioner 4, thereby improving the sealing effect of the air conditioner 4 and reducing the risk of water ingress.

[0059] The specific installation method is: firstly, the second sealing gasket 9 is pasted on the first boss 11 and the second boss 18, and then the air conditioner 4 is installed from top to bottom. At this time, the second sealing gasket 9 is in a compressed state. Then, the lateral position of the air conditioner bracket 3 is adjusted so that the roof fastening part 32 of the air conditioner bracket 3 is close to the first boss 11, and then the first fastener fastens the air conditioner bracket 3. Finally, the first sealing gasket 8 is inserted into the gap between the bottom surface of the air conditioner 4 and the roof for sealing.

[0060] In addition, the second sealing gasket 9 can be a frame-shaped frame having the same size as the frame surrounded by the first boss 11 and the second boss 18 , so that the second sealing gasket 9 can be laid on the first boss 11 and the second boss 18 as a whole.
