Description

Technical Field

[0001] This utility model relates to the field of vehicle air compressor technology, specifically, to a hybrid mining car and its electric air compressor air intake arrangement structure. Background Technology

[0002] Currently, most hybrid mining trucks on the market use electric air compressor intake systems that provide the necessary compressed air to the entire vehicle by separately installing air filters, mufflers, and connecting pipelines. However, the layout of a hybrid mining truck is already quite complex due to the involvement of the engine. Adding the installation of related components for the electric air compressor intake system further complicates the process, and the various connecting pipelines can easily lead to installation errors and interference. Reducing the number of related components would greatly benefit the overall vehicle layout. Utility Model Content

[0003] To address the aforementioned technical problems, the present invention aims to provide a hybrid mining truck and its electric air compressor air intake arrangement structure, which utilizes the engine air filter as the air source for the electric air compressor, directly drawing air from behind the engine air filter to provide compressed air for the entire vehicle; thereby reducing the types of vehicle parts and optimizing the overall vehicle layout.

[0004] The present invention solves the above problems through the following technical solution:

[0005] A hybrid mining truck electric air compressor air intake arrangement structure includes: an electric air compressor, the air compressor inlet of the electric air compressor being connected to an air intake port on the side of an air intake steel pipe via a connecting hose III; the two ends of the air intake steel pipe are respectively connected to an engine air filter and an engine turbocharger, so that the engine air filter is used as the compressed air source for the electric air compressor.

[0006] As a further improvement, the air intake is formed by a circular hole on the side of the air intake steel pipe and a straight steel pipe welded at the position of the circular hole.

[0007] As a further improvement, the two ends of the connecting hose III are respectively fitted onto the air intake port of the air inlet steel pipe and the air inlet of the air compressor, and are fixed and locked with clamps.

[0008] As a further improvement, the intake steel pipe is L-shaped, and each end is connected to an intake steel pipe connecting hose, so that the other ends of the two intake steel pipe connecting hoses can be connected to the engine air filter and the engine turbocharger respectively.

[0009] As a further improvement, the intake steel pipe connecting hose is fixed and locked to the intake steel pipe and / or the engine air filter and / or the engine turbocharger by clamps.

[0010] As a further improvement, the intake steel pipe is provided with a fixed bracket for installing and fixing the intake steel pipe.

[0011] As a further improvement, the electric air compressor air intake arrangement structure also includes: an electric air compressor, a connecting hose IV, a condenser, and a dryer. The connecting hose IV is used to connect the air compressor outlet on the side of the electric air compressor away from the air compressor inlet to the condenser. The condenser is connected to the dryer so that the gas compressed by the electric air compressor is cooled by the condenser and then dried by the dryer so that the dried gas can then provide an air source for the vehicle.

[0012] As a further improvement, the connecting hose IV is connected to the condenser via a connecting steel pipe, so that the connecting steel pipe can perform preliminary cooling on the gas compressed by the electric air compressor.

[0013] As a further improvement, the connecting steel pipe is spiral-shaped.

[0014] Furthermore, this utility model also solves the above problems through the following technical solutions:

[0015] A hybrid mining car is equipped with the air intake arrangement structure of the electric air compressor of the hybrid mining car as described above.

[0016] Compared with the prior art, this utility model has the following advantages and beneficial effects:

[0017] This utility model's electric air compressor draws air directly from behind the engine air filter, eliminating the need for an additional air filter, muffler, and piping previously required. This design allows the electric air compressor to directly draw clean air filtered by the engine air filter to provide the vehicle with the necessary compressed air. Furthermore, the air filtered by the engine air filter is more effective at removing impurities and moisture compared to the air filter previously installed in air compressors, resulting in cleaner air. This extends the service life of related components and significantly improves their reliability. Attached Figure Description

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Example 1:

[0025] See attached document Figure 1 A hybrid mining truck electric air compressor air intake arrangement structure includes: an electric air compressor 1, an air compressor inlet 2 of the electric air compressor connected to a connecting hose I 3, and a muffler 4, a connecting hose II 5 and an air compressor air filter 6 connected in sequence through the connecting hose I 3, and the air compressor air filter 6 provides the required compressed air to the whole vehicle.

[0026] Specifically, the electric air compressor 1 provides compressed air to the entire vehicle, ensuring the gas pressure in the air tank and meeting the vehicle's usage requirements. The air compressor inlet 2 is used to obtain clean gas from the outside. Connecting hose I 3 is used to connect the air compressor inlet 2 and the muffler 4, which helps reduce air noise; connecting hose II 5 connects the muffler 4 and the air filter 6, which is used to filter air impurities and moisture.

[0027] Example 2:

[0028] See attached document Figure 2 An improved air intake arrangement structure for a hybrid mining truck electric air compressor, based on Embodiment 1, includes: an electric air compressor 1, with its air inlet 2 connected to an opening on the side of an intake steel pipe 8 via a connecting hose III 9; the intake steel pipe 8 is connected at both ends to an engine air filter 7 and an engine turbocharger, respectively, so that the engine air filter 7 serves as the compressed air source for the electric air compressor 1. Since the engine air filter element of the engine air filter can filter impurities, moisture, and reduce noise, when the engine air filter 7 is used as the compressed air source for the electric air compressor, there is no need to install a muffler 4 or other structures on the connecting hose III, thus further reducing the number of components in the electric air compressor air intake arrangement structure.

[0029] In one alternative, the intake steel pipe 8 has an opening on its side; that is, a round hole on the side of the intake steel pipe 8, and a straight steel pipe with an outer diameter of 25mm is welded at the position of the round hole, which serves as the air intake port for the electric air compressor to take air from the engine air filter 7.

[0030] As a preferred option, the connecting hose Ⅲ9 connects the air intake steel pipe 8 and the air compressor inlet 2; both ends of the connecting hose Ⅲ are respectively fitted onto the air intake port of the air intake steel pipe and the air compressor inlet, and after installation, they are fixed and locked with clamps.

[0031] In another alternative, considering the height difference between the engine air filter 7 and the engine turbocharger, refer to the appendix. Figure 2 Since the engine air filter 7 is generally located on the right platform of the mine car, and the air intake of the engine turbocharger is located below the cab, the engine air filter 7 and the engine turbocharger cannot be connected with a right-angle pipe. Usually, a special-shaped hose is required for connection. At the same time, since the hose is too long after connection, it is easy to deform when the engine is intakeing air. Therefore, in this embodiment, an intake steel pipe 8 is used for transition connection. The intake steel pipe 8 is L-shaped, and both ends are connected to intake steel pipe connecting hoses 81, so that the other end of the intake steel pipe connecting hose 81 is connected to the air intake of the engine air filter 7 and the engine turbocharger respectively, so as to utilize the deformation of the intake steel pipe connecting hose 81 to adapt to the installation.

[0032] Preferably, the connection between the intake steel pipe connecting hose 81 and the mating component can be reinforced and fixed by clamps.

[0033] Furthermore, a fixed bracket can be installed at the intake steel pipe 8 to install and fix the intake steel pipe 8, and to fix and lock the entire connecting pipeline.

[0034] Example 3:

[0035] See attached document Figure 3An improved air intake arrangement structure for an electric air compressor in a hybrid mining truck, based on Embodiment 2, further includes: an electric air compressor 1, a connecting hose IV 10, a connecting steel pipe 11, a condenser 12, and a dryer 13. One end of the connecting hose IV 10 is connected to the air outlet of the electric air compressor 1 on the side away from the air compressor inlet 2, and the other end is connected to one end of the connecting steel pipe 11. The other end of the connecting steel pipe is connected to the condenser 12, which is also connected to the dryer 13 via a pipeline. The condenser 12 cools the gas compressed by the electric air compressor, and the dryer 13 dries the cooled gas, so that the dried gas can then provide an air source for the entire vehicle. Because the air is compressed into a high-temperature, high-pressure gas after passing through the electric air compressor, the condenser is needed to cool the gas. After the high-temperature, high-pressure gas is cooled by the condenser, water vapor is generated in the gas, which is then dried by the dryer, and the dried gas then provides an air source for the entire vehicle.

[0036] In this embodiment, the connecting steel pipe 11 is spiral-shaped so that the connecting steel pipe 11 can initially cool the gas compressed by the electric air compressor; the high-temperature and high-pressure gas passes through the inside of the connecting steel pipe and dissipates heat through convection with the air.

[0037] Example 4:

[0038] A hybrid mining car is provided with an air intake arrangement structure for an electric air compressor, as described in any of Embodiments 1, 2, or 3.

[0039] Although the present invention has been described herein with reference to illustrative embodiments, the above embodiments are merely preferred embodiments of the present invention, and the implementation of the present invention is not limited to the above embodiments. It should be understood that those skilled in the art can design many other modifications and implementations, which will fall within the scope and spirit of the principles disclosed in this application.
