A roof-mounted bus air conditioner base and an air conditioner base including replacement parts

Abstract

This application relates to a roof-mounted bus air conditioner base and an air conditioner base including a replacement component. The connecting support is a replacement component. By providing connecting supports of various specifications and preset angles, one can be selected to connect the fixed frame to the first evaporator module or the second evaporator module. Because the second fixing surface, the first fixing surface, and the fixed frame form a preset angle, the relative angle between the first and second evaporator modules and the fixed frame after fixation conforms to the preset angle. Therefore, when the roof-mounted bus air conditioner base of this utility model needs to be installed on the roof of different types of buses, different connecting supports can be selected according to the specific bus size to change the angle formed between the first and second fixing parts and the fixed frame after fixation. This allows for a close fit with different types of bus roofs, ensuring necessary sealing performance, improving versatility, and reducing design and modification costs.

[0053] Example

[0054] This embodiment provides a roof-mounted bus air conditioner base, such as Figure 1 As shown, it includes: a fixed frame 1, a connecting support 2, a first evaporation chamber module 3 and a second evaporation chamber module 4. The first evaporation chamber module 3 and the second evaporation chamber module 4 are respectively arranged on both sides of the fixed frame 1. The fixed frame 1 is fixed to the first evaporation chamber module 3 or the second evaporation chamber module 4 by the detachable connecting support 2.

[0055] like Figure 2 , Figure 3 As shown, the first evaporation chamber module 3 and the second evaporation chamber module 4 both have a first fixing part 31 and a second fixing part 32 for connection; the connecting support 2 has a first fixing surface 21 for the first fixing part 31 to be attached and fixed, and a second fixing surface 22 for the second fixing part 32 to be attached and fixed, and the second fixing surface 22, the first fixing surface 21 and the fixing frame 1 are at a preset angle.

[0056] The roof-mounted bus air conditioner base provided in this embodiment first modularizes the main body of the air conditioner base into a fixed frame 1, a first evaporator module 3, and a second evaporator module 4. The first evaporator module 3 and the second evaporator module 4 are respectively arranged on both sides of the fixed frame 1 (e.g., the left and right sides). The fixed frame 1 is fixed to the first evaporator module 3 or the second evaporator module 4 by a detachable and replaceable connecting support 2. Both the first evaporator module 3 and the second evaporator module 4 have a first fixing part 31 and a second fixing part 32 for connection; the connecting support 2 has a first fixing surface 21 for the first fixing part 31 to be attached and fixed, and a second fixing surface 22 for the second fixing part 32 to be attached and fixed.

[0057] The roof-mounted bus air conditioner base provided in this embodiment uses a replacement connecting support 2. This embodiment provides three types of connecting supports 2 with preset angles, one of which is used to connect the fixing frame 1 to the first evaporator module 3 or the second evaporator module 4. Because the second fixing surface 22, the first fixing surface 21, and the fixing frame 1 form a preset angle, the relative angle between the first evaporator module 3 and the second evaporator module 4 and the fixing frame 1 after fixation conforms to the preset angle. Therefore, when the roof-mounted bus air conditioner base of this utility model needs to be installed on the roof of different types of buses, different connecting supports 2 can be selected to change the angle formed between the first fixing part 31 and the second fixing part 32 and the fixing frame 1 after fixation, enabling it to fit snugly on the roof of different types of buses, ensuring necessary sealing performance, improving versatility, and reducing design and modification costs.

[0058] Understandably, in other embodiments, the specifications of the connecting support 2 may be two, four, five or more.

[0059] like Figure 4 As shown, taking the connecting support 2 with two preset angle specifications as an example, one is a preset angle of 2.5° and the other is a preset angle of 4.1°. When the same parts of the two are overlapped, it can be seen that most of the positions of the two are completely consistent. The difference lies in the angle difference between the first fixing surface 21 and the second fixing surface 22 of the two.

[0060] like Figures 5-7 As shown, the main beam 11 of the fixed frame 1 and the second evaporation chamber module 4 are connected by connecting supports 2 with preset tilt angles of 2.5°, 4.1° and 5.5° respectively. After fixing, the second evaporation chamber module 4 and the main beam 11 are tilted at 2.5°, 4.1° and 5.5° respectively.

[0061] In an alternative embodiment, such as Figure 1 , Figure 8As shown, the roof-mounted bus air conditioner base also includes an inner body connecting beam 6 and an outer body connecting beam 7. The inner body connecting beam 6 is detachably fixed to the side of the first evaporator module 3 and the second evaporator module 4 near the fixing frame 1, for connection to the inner side of the bus roof; the outer body connecting beam 7 is detachably fixed to the side of the first evaporator module 3 and the second evaporator module 4 away from the fixing frame 1, for connection to the outer side of the bus roof. In this embodiment, the arrangement of the inner body connecting beam 6 and the outer body connecting beam 7 facilitates the fixing of the first evaporator module 3 and the second evaporator module 4 to the roof and promotes a tighter contact with the roof. The inner body connecting beam 6 and the outer body connecting beam 7 can be assembled and fixed to the first evaporator module 3 or the second evaporator module 4 via connectors 9.

[0062] In this embodiment, replacement parts for the inner body connecting beam 6 and the outer body connecting beam 7 are also provided, including three different specifications. When replacing the connecting support 2, in order to make the inner body connecting beam 6 and the outer body connecting beam 7 fit the roof better, the inner body connecting beam 6 and the outer body connecting beam 7 can be replaced with other specifications at the same time.

[0063] In an alternative embodiment, such as Figure 1 , Figure 8 , Figure 9 As shown, the roof-mounted bus air conditioner base also includes a sealing strip 5. The sealing strip 5 is arranged around the edges of the first evaporator module 3 and the second evaporator module 4 to seal the gaps between the first evaporator module 3 and the second evaporator module 4 and the bus roof. In this embodiment, by using the sealing strip 5 around the edges of the first evaporator module 3 and the second evaporator module 4, it is possible to ensure that there is no leakage between the edges of the first evaporator module 3 and the second evaporator module 4 and the bus roof. Since the sealing strip 5 has a certain deformation capacity, when the connecting support 2 of this embodiment is replaced, the sealing strip 5 can adapt completely without replacement.

[0064] In an alternative embodiment, such as Figure 9 As shown, the fixed frame 1 includes a main crossbeam 11 and a condenser frame 12. The condenser frame 12 is at least partially located above the main crossbeam 11, and serves as the frame for the condenser module, providing a certain degree of support. After the roof-mounted bus air conditioning base of this embodiment is installed on the roof of the bus, the main crossbeam 11 extends horizontally; as shown... Figure 2 As shown, both the main crossbeam 11 and the condenser frame 12 are fixed to the connecting support 2 via detachable connectors 9. In this embodiment, the connecting support 2 is fixed to both the main crossbeam 11 and the condenser frame 12 simultaneously to ensure the stability of the connecting support 2 during fixing and to prevent loosening or shaking after assembly.

[0065] In an alternative embodiment, such as Figure 3As shown, the connecting support 2 includes: a support body 20, a horizontal connecting hole 23, and a vertical connecting hole 24. The horizontal connecting hole 23 is opened horizontally in the support body 20 for the main crossbeam 11 to be fixed by the connector 9; the vertical connecting hole 24 is opened vertically in the support body 20 for the condenser frame 12 to be fixed by the connector 9. In this embodiment, by staggering the horizontal connecting hole 23 and the vertical connecting hole 24, the space of the support body 20 is fully utilized, the force on the support body 20 is distributed, and the stability during fixing is improved.

[0066] In an alternative embodiment, such as Figure 3 As shown, the connecting support 2 has a first fixing hole 211 for the connecting member 9 to pass through at the location of the first fixing surface 21, and a second fixing hole 221 for the connecting member 9 to pass through at the location of the second fixing surface 22. Figure 2 As shown, the first fixing part 31 and the second fixing part 32 have corresponding mounting holes at the positions of the first fixing hole 211 and the second fixing hole 221, and the connector 9 is connected and fixed through these mounting holes. In this embodiment, by opening fixing holes at the positions of the first fixing surface 21 and the second fixing surface 22, it can be ensured that when the connector 9 is locked, the first fixing part 31 and the second fixing part 32 are tightly attached to the first fixing surface 21 and the second fixing surface 22, thus avoiding the installation angle not reaching the expected value.

[0067] In an alternative embodiment, such as Figure 3 As shown, the connecting support 2 has several hollow areas 25 to reduce the weight of the connecting support 2.

[0068] In an alternative embodiment, such as Figure 8 As shown, the cross-section of the inner body connecting beam 6 or the outer body connecting beam 7 is U-shaped, which can improve the structural strength and facilitate close contact with the roof of the bus.

[0069] In an alternative embodiment, such as Figures 5-7 As shown, the support body 20 extends along the side wall of the first evaporation chamber module 3 or the second evaporation chamber module 4 near the fixed frame 1, thereby ensuring sufficient cross-sectional area within a limited space and improving structural strength.

[0070] This embodiment provides a method for selecting the connecting support 2, inner body connecting beam 6, and outer body connecting beam 7 for bus roofs of different sizes, such as... Figure 10As shown, a selection form is established for the bus roof bending radius, the design curvature of the connecting support 2, the height of the inner body connecting beam 6, and the height of the outer body connecting beam 7. Based on the required bus roof bending radius, the necessary connecting support 2, inner body connecting beam 6, and outer body connecting beam 7 are selected according to the form to ensure a proper fit when the roof-mounted bus air conditioner base provided in this embodiment is installed on the target bus roof. Optionally, connecting supports 2 of different specifications can be painted in different colors for easy identification by operators.

[0071] Based on the above-described preferred embodiments according to this application, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the technical concept of this application. The technical scope of this application is not limited to the contents of the specification, but must be determined according to the scope of the claims.
