[0002] like Figure 1 As shown, the installation method of the existing passenger car roof air conditioner is usually: the bolt is passed upward through the roof cover, and the head of the bolt is fixed under the roof cover by using a bent plate for welding, and the threaded part of the bolt is located outside the roof cover for installing the air conditioner.

[0003] However, since the threaded portion of the bolt is located outside the roof cover, even if sealant is applied to the threaded portion of the bolt, a large amount of sealant cannot be accumulated at the position where the bolt of the roof cover is penetrated, and water leakage in the car is still likely to occur.

[0004] In addition, there are many types of air conditioners, and the positions of the holes for the bolts on the roof cover need to be adjusted according to the type of air conditioner, which leads to a wide variety of bus roof covers and poor commonality of the roof covers.

[0005] It can be seen that the existing technology still needs to be improved and developed. Utility Model Content

[0006] In view of the above-mentioned defects of the prior art, the utility model provides a passenger car roof air conditioner installation structure and a passenger car, aiming to solve the problem that the existing passenger car roof air conditioner installation method leads to poor universality of the roof cover.

[0007] The technical solution adopted by the utility model to solve the technical problem is as follows:

[0008] A mounting structure for a passenger car top air conditioner comprises a roof cover; and further comprises:

[0009] at least two mounting plates, the mounting plates being fixed to the upper portion of the roof cover;

[0010] studs, the studs are vertically welded to the mounting plate;

[0011] a first sealant layer, the first sealant layer being located between the roof cover and the mounting plate;

[0033] In order to make the purpose, technical solution and advantages of the utility model clearer and more specific, the utility model is further described in detail with reference to the accompanying drawings and examples. 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.

[0034] In the description of the present utility model, it should be understood that the terms "upper", "lower", "left", "right", etc. indicating directions or positional relationships are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, and a specific direction structure and operation, and therefore, cannot be understood as a limitation on the present utility model. In addition, "first" and "second" are only used for descriptive purposes, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present utility model, unless otherwise specified, "multiple" means more than two.

[0035] See also Figures 2 to 6 The utility model provides a mounting structure for a passenger car top air conditioner, comprising a roof cover 3. The roof cover 3 is a part of the passenger car body and is located on the top of the passenger car body. Further, it also comprises a mounting plate 4, a stud 5, a first sealing adhesive layer and a fixing bolt 6.

[0036] There are at least two mounting plates 4 , which are fixed to both sides of the upper part of the roof cover 3 to ensure that the air conditioner can be installed firmly.

[0037] The stud 5 is vertically welded on the mounting plate 4, and is a rod body with threads, and does not have the same structure as the head of the fixing bolt 6. In the utility model, the stud 5 is used to install and fix the roof air conditioner.

[0038] The first sealant layer is located between the roof cover 3 and the mounting plate 4, and plays the role of bonding the roof cover 3 and the mounting plate 4, and also can achieve a sealing effect. When water accumulates on the roof cover 3, it is not easy for the water to enter the gap between the roof cover 3 and the mounting plate 4, and then will not drip down from the bolt holes on the roof cover 3 into the vehicle.

[0039] The head of the fixing bolt 6 is located on the upper part of the mounting plate 4, and the fixing bolt 6 passes through the mounting plate 4 and the roof cover 3 in sequence. The fixing bolt 6 plays the role of fixing the mounting plate 4 on the roof cover 3.

[0040] It can be seen that the utility model replaces the bolts used for installing and fixing the roof air conditioner with studs 5, and welds the screws directly to the mounting plate 4 instead of the roof cover 3. In this way, when replacing other types of roof air conditioners, the construction personnel only need to replace the mounting plate 4 with another screw layout, and the bolt fixing position of the mounting plate 4 on the roof cover 3 can remain unchanged. Therefore, when installing different types of roof air conditioners, the roof cover 3 does not need to make any structural changes, so that it can adapt to the installation of different types of roof air conditioners, and the roof cover 3 is also more universal.

[0041] Furthermore, the second sealant is piled around the head of the fixing bolt 6. Since the head of the fixing bolt 6 has more contact surface than the threaded portion of the fixing bolt 6, when the second sealant is piled on the head of the fixing bolt 6, more second sealant can be piled, and even if the second sealant is aged and cracked, the probability of water leakage is very low.

[0042] In addition, since the first sealant layer can also play a sealing role, the utility model has a double-layer sealing structure, which can enhance the sealing performance of the vehicle body.

[0043] Furthermore, a first gasket 7 is sleeved on the fixing bolt 6; the first gasket 7 is located on the upper part of the roof cover 3, and the head of the fixing bolt 6 is pressed tightly. The first gasket 7 can not only absorb the stress generated by the impact and vibration at the bolt connection, but also has a sealing function, which can enhance the dustproof and waterproof properties of the bolt connection.

[0044] like Figure 5 and Figure 6 As shown, further, a nut 8 and a second gasket 9 are also sleeved on the fixing bolt 6; the nut 8 and the second gasket 9 are both located at the lower part of the roof cover 3; wherein, the nut 8 is used to prevent the fixing bolt 6 from loosening; the second gasket 9 is located between the nut 8 and the second gasket 9, and its function is the same as that of the first gasket 7, both of which are used to absorb the stress generated by impact and vibration at the bolt connection, and at the same time enhance the dustproof and waterproof performance of the bolt connection.

[0045] like Figure 5 and Figure 6 As shown, further, an elastic washer 10 is sleeved on the fixing bolt 6; the elastic washer 10 is located between the nut 8 and the second gasket 9. The elastic washer 10 can absorb vibration and impact at the bolt connection, reduce noise, and also prevent the fixing bolt 6 from loosening.

[0046] Furthermore, the roof cover 3 is a carbon fiber composite board. The carbon fiber composite board can be doped with carbon fiber and glass fiber, and the carbon fiber and glass fiber can enhance the mechanical properties of the composite board, so that the strength and rigidity of the roof cover 3 can be improved.

[0047] In addition, since the specific gravity of carbon fiber composite plates is lower than that of steel plates, the use of carbon fiber composite plates can further reduce the weight of the bus body. Without affecting the strength and rigidity of the body, the lightweight degree of the entire vehicle can be further improved.

[0048] like Figure 5 As shown, further, a sandwich layer 31 is provided in the roof cover 3, and a PVC foam board is provided in the sandwich layer 31. The PVC foam board can prevent the noise and vibration generated during the driving of the vehicle from propagating into the vehicle body, and the NVH performance (noise, vibration and harshness) can be improved compared with the traditional structure of the bus body.

[0049] Furthermore, the mounting plate 4 may be a steel plate. The steel plate has a high tensile strength and can withstand the tensile stress generated by the vehicle during driving, thereby maintaining the stability of the air conditioner installation position.

[0050] like Figure 2 As shown, further, a plurality of weight-reducing holes 41 are distributed on the mounting plate 4, which can not only improve the lightweight degree of the whole vehicle, but also reduce the material cost.

[0051] The utility model also provides a bus, comprising the above-mentioned installation structure of the bus top air conditioner.

[0052] To sum up, the utility model replaces the bolts used for installing and fixing the roof air conditioner with studs, and welds the screws directly to the mounting plate instead of the roof cover. In this way, when replacing other models of roof air conditioners, the construction personnel only need to replace the mounting plate with another screw layout, and the bolt fixing position of the mounting plate on the roof cover can remain unchanged. Therefore, when installing different models of roof air conditioners, the roof cover does not need to make any structural changes, so that it can adapt to the installation of different types of roof air conditioners, and the roof cover is also more universal.

[0053] It should be understood that the application of the present invention is not limited to the above examples. For ordinary technicians in this field, improvements or changes can be made according to the above description. All these improvements and changes should fall within the scope of protection of the claims attached to the present invention.
