Description

Technical Field

[0001] This utility model relates to the field of automotive engine brackets, specifically to a front exhaust side bracket for a dual-air conditioning engine and an automobile. Background Technology

[0002] With the continuous development and increasing demand in the cold chain logistics market, the need to convert cargo trucks into refrigerated trucks is also growing. Currently, to meet the requirements of refrigerated transportation, a series of modifications to cargo trucks are necessary, mainly including adjustments to the chassis, air conditioning compressor, and their installation methods. However, these modifications face some challenges and shortcomings.

[0003] Current technical solutions typically employ larger chassis for refrigerated trucks to accommodate the installation of refrigeration systems. However, this alters the original chassis configuration of the cargo truck, resulting in lower standardization. Furthermore, adjusting the number and location of the air conditioning compressors necessitates changes to the existing piping routes, often requiring damage to the original air intake pipes, potentially impacting vehicle performance. Additionally, the installation of the superstructure compressor often involves hoisting and fixing, which not only increases the risk of malfunctions but also raises the difficulty and cost of maintenance.

[0004] In summary, under current technological conditions, the modification of refrigerated trucks faces challenges such as changes in chassis condition, alterations to pipeline routes, and complex installation of the superstructure compressor. These issues directly affect the modification efficiency and performance of refrigerated trucks. Utility Model Content

[0039] The following detailed description, in conjunction with the accompanying drawings, outlines some embodiments of the present invention. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0040] Example 1

[0041] Reference Figures 1-3 This embodiment provides a front exhaust side bracket 1 for a dual-air conditioning engine, comprising:

[0042] Cylinder block connecting part 5, wherein a plurality of cylinder block connecting holes 501 for connecting the engine cylinder block are provided on the cylinder block connecting part 5;

[0043] Support part 7, the support part 7 having a rubber support mounting hole 701, the support part 7 being used to support the engine and the rubber support mounting hole 701 being used to assemble the engine's rubber support;

[0044] The air conditioning compressor mounting part 15 has an air conditioning compressor bracket mounting surface 10 for mounting the air conditioning compressor mounting bracket 3, and the air conditioning compressor mounting bracket 3 is used to mount the cab air conditioning compressor 4.

[0045] The idler wheel mounting part 12 is located on the side of the air conditioning compressor. The idler wheel mounting part 12 has an idler wheel mounting hole 1201 for mounting the idler wheel 2 of the front wheel system of the car. It can be adapted to the optimization of the wheel system structure and reduce the risk of interference.

[0046] Reinforcing ribs are used to improve the overall structural strength.

[0047] The first plate 13, the cylinder body connecting part 5 and the support part 7 are connected through the first plate 13;

[0048] The cylinder body connecting part 5 and the support part 7 are connected through the first plate 13.

[0049] The reinforcing rib structure includes an upper rib 6, which connects the cylinder body connecting part 5, the support part 7, and the first plate 13, thereby strengthening the connection between the cylinder body connecting part 5, the support part 7, and the first plate 13.

[0050] The reinforcing rib structure also includes a lower rib 9 and an oblique rib 8. The first side of the first plate 13 and the first side of the second plate 14 are on the same side, and the first side of the first plate 13 and the first side of the second plate 14 are connected and fixed through the lower rib 9. The second side of the first plate 13 and the second side of the second plate 14 are on the same side, and the second side of the first plate 13 and the second side of the second plate 14 are connected and fixed through the oblique rib 8. A hollow structure is formed between the lower rib 9 and the oblique rib 8. This hollow structure enables the lightweight design of the bracket and reduces the overall weight of the bracket. Combined with the design of the reinforcing rib structure, the overall structural strength of the bracket is guaranteed or improved on the basis of lightweight design.

[0051] By reinforcing the rib structure, the main stress-bearing positions of the engine support are strengthened, thereby improving the structural strength.

[0052] It is important to note that the engine cylinder block is one of the core components of the engine. It is a metal main structure with multiple cylinder bores (or cylinder liners). Each cylinder bore contains a piston, which moves up and down within the cylinder bore. The main functions of the cylinder block include:

[0053] 1. To accommodate piston movement: The piston moves up and down within the cylinder bore to complete the energy conversion generated by burning fuel.

[0054] 2. Cooling and lubrication: The cylinder body usually has cooling water channels and lubricating oil passages to maintain a suitable temperature and lubricate the piston and cylinder walls.

[0055] 3. Connecting other components: The cylinder block is tightly connected to other engine components (such as the crankcase, cylinder head, etc.) to form a complete engine structure.

[0056] Engine rubber mounts are devices used to reduce the transmission of engine vibrations to the chassis and other body components. They are typically made of rubber and sometimes have embedded metal plates to enhance their strength and stability. Here are some key characteristics and functions of engine rubber mounts:

[0057] 1. Vibration damping: The engine generates vibrations when it is running. If these vibrations are not controlled, they may be transmitted to the frame and body, causing noise and discomfort. Rubber supports can absorb and isolate these vibrations, improving ride comfort.

[0058] 2. Sound insulation effect: Rubber has good sound insulation properties, which can effectively reduce the transmission of engine noise and further enhance the driving experience.

[0059] 3. Position Fixation: The rubber support secures the engine to the correct position on the chassis through specific mounting holes (i.e., the rubber support mounting holes 701). These rubber support mounting holes 701 are located at the bottom of the engine, ensuring smooth engine operation.

[0060] 4. Durability: Rubber materials have good elasticity and durability, and can maintain their performance for a long time under various working conditions, ensuring the long-term stable operation of the engine.

[0061] In this embodiment, the air conditioner compressor mounting part 15 adopts a plate-like structure. The height of the air conditioner compressor mounting part 15 ranges from 160 to 180 mm. The air conditioner compressor mounting part 15 and the idler wheel mounting part 12 are integrally formed, and the thickness of the idler wheel mounting part 12 ranges from 22 to 26 mm. Four bracket mounting holes 11 are provided on the air conditioner compressor mounting part 15 for assembling the air conditioner compressor bracket. The four bracket mounting holes 11 are rectangularly distributed. It should be noted that in the prior art, the overall height of the air conditioner compressor mounting part 15 is 241 mm, the thickness of the idler wheel mounting part 12 is 12 mm, and the existing air conditioner compressor mounting part 15 also has four rectangularly distributed bracket mounting holes 11. However, the solution provided in this application, by shortening the overall height of the air conditioner compressor mounting part 15, raises the height of the four bracket mounting holes 11 simultaneously. This increases the compressor's ground clearance after installation, reducing the risk of impact from ground debris and thus lowering the failure rate. Furthermore, since the connection between the idler wheel mounting part 12 and the inclined rib part 8 is a weak point in the support structure, this solution increases the thickness of the idler wheel mounting part 12 to improve the strength of the support structure and ensure a sufficient safety factor.

[0062] The driver's cab air conditioning compressor 4 is installed in the vehicle's driver's cab and is responsible for regulating the temperature and humidity inside the vehicle. It is an important component of the automotive air conditioning system, and its main functions include:

[0063] 1. Compressing the refrigerant: The air conditioner compressor compresses the refrigerant (such as Freon) to increase its temperature and pressure. The compressed refrigerant then enters the condenser.

[0064] 2. Circulating refrigerant: The compressor drives the refrigerant to circulate between the evaporator and condenser, thereby achieving the heat absorption and release process.

[0065] 3. Providing power: The compressor is usually driven by an engine via a belt, or in an electric vehicle it may be driven directly by an electric motor.

[0066] The "air conditioning compressor mounting bracket 3" mentioned in this solution refers to a structure specifically designed for fixing and installing the cab air conditioning compressor 4. This air conditioning compressor mounting bracket 3 not only provides a fixing point for the compressor but also ensures the correct position and angle of the compressor to ensure the normal operation of the air conditioning system. Specifically:

[0067] - Installation location: The air conditioning compressor mounting bracket 3 provides a fixed position for the compressor in the cab, so that it will not move due to vehicle vibration.

[0068] -Strength and stability: The bracket design enhances the stability of the compressor and reduces vibration and noise.

[0069] - Ground clearance: Increases the compressor's height above the ground, reducing the risk of impact from ground debris and thus lowering the failure rate.

[0070] - Compact structure: This makes the overall structure of the support compact and improves space utilization.

[0071] Example 2

[0072] In this embodiment, the overall height of the air conditioning compressor mounting part 15 of the front exhaust side bracket 1 of the dual air conditioning engine is 174mm, which is 67mm higher than the existing technology (the existing air conditioning compressor mounting part 15 is 241mm high). At the same time, the height of the four bracket mounting holes 11, the air conditioning compressor bracket, and the actual height of the air conditioning compressor after installation are also increased. The thickness of the idler wheel mounting part 12 is 24mm, which is twice as thick as the existing idler wheel mounting part 12, strengthening the weak points and reducing the failure rate.

[0073] This solution reduces the overall volume of the front exhaust side bracket by about 30% through the design of the bracket, doubles the thickness of the idler wheel mounting part 12, reduces the weight by 10%, increases the safety factor by 0.3 under dual air conditioning compressor conditions, and improves the bracket's versatility, ultimately greatly improving the convenience of converting cargo trucks into refrigerated trucks.

[0074] Example 3

[0075] An automobile includes a dual-air conditioning engine and a front exhaust side bracket for the dual-air conditioning engine.

[0076] The beneficial effects of the technical solution of this utility model are:

[0077] This application provides a front exhaust side bracket 1 for a dual-air conditioning engine and an automobile. A cylinder block connection hole 501 is used for the assembly between the entire bracket and the engine cylinder block, and a rubber support mounting hole 701 is used for the assembly between the bracket and the engine rubber support. The main function of this bracket is to provide support for the engine. The air conditioning compressor bracket mounting surface 10 provides an installation position for the air conditioning compressor mounting bracket 3. Compared to existing technologies, the height of the air conditioning compressor mounting part 15 is reduced, resulting in a lower overall height. This increases the compressor's ground clearance during installation, reduces the compressor's failure rate, and makes the engine structure more compact, increasing engine reliability. The idler wheel mounting hole 1201 connects to the idler wheel 2 of the front wheel system of the automobile. This overall bracket design allows for optimization of the wheel system structure, reduces interference risks, improves the bracket's versatility, and ultimately greatly improves the convenience of converting a cargo truck into a refrigerated truck.
